New paradigms in the research and development of nanocarbon thin films are providing the bases for new physics, new materials science and chemistry, and their impact in a new generation of multifunctional biomedical devices. This talk will focus on discussing the science and technology of thenew paradigm material named ultrananocrystalline diamond (UNCDTM) in thin film form and integration into a new generation of medical devices and implants as described below: UNCDfilms co-developed and patented by O. Auciello and colleagues are synthesized by novel microwave plasma chemical vapor deposition and hot filament chemical vapor deposition techniques using an Ar-rich/CH4 chemistry that produces films with 2-5 nm grains.The fundamental science underlying the synthesis and properties of the UNCD films and applications to devices will be discussed. The UNCD films exhibit the lowest friction coefficient (0.02-0.04) compared with metals (≥ 0.5) currently used in many prostheses (e.g., hips, knees), electrically conductive UNCD coatings with nitrogen in grain boundaries can enable a new generation of neural electrodes, UNCD coatings are extremely biocompatible. Original Biomedical Implants (OBI-USA) and OBI-México, founded by Auciello and colleagues, are developing new generations of implantable medical devices based on the biocompatible UNCD coatings, namely: a) UNCD-coated silicon based microchip implantable inside the eye as a key component of the artificial retina to return partial vision to blind people by genetically-induced degeneration of photoreceptors; b) new generation of Li-ion batteries with ≥ 10x longer life and safer, using UNCD-based electrodes, membranes and inner wall battery case, enable next generation of defibrillator/pacemakers; c) new generation of implantable prostheses (e.g., dental implants, hips, knees) coated with UNCD eliminates failure of current metal-based implants due to synergistic mechanical wear / chemical corrosion by body fluids; d) UNCD-coated polymer with brain neurons tailored stiffness enables next generation less invasive electrodes for neural stimulation.

Medicine and food have a common origin. A food can be regarded as ‘functional’ If it is satisfactorily able to demonstrate its beneficial effects on one or more target functions in the body thus improving the state of health and strengthening the well being and or participating in reduction of risk of diseases . Such nutriceulicals in broader term must remains as component of food rather than individually as capsule or in other forms. There is increasing evidences that sulfur amino acids (SAA) play an important metabolic and functional role in human health and decease prevention. It is further observed that SAA also provide elemental Sulfur require for growth and development, and in general, it is source of energy and nutrient needs of various life processes. Taurine, chemically; 2 Amino Ethane Sulfonic acid, belongs to glutathione family and is a major sulfur containing amino acid, constitute about 0.1 % of normal human body weight (70 Kg) and has long been placed under such category. To add little more the best-known functional food until now is mother’s milk of which taurine is component but it lacks in cow’s milk on which majority of human survive.. It is possible and feasible to modulate target functions via food supplemented with such agents. Taurine supplemented food and formula have provided long range of beneficial effects, almost covering the entire life activities and even before in embryonic development, a acute taurine deficiency if carry out may come under classification of ‘disease of generation ‘leading to several form of disabilities. The role of taurine is increasing and it is now regarded ‘multiple molecule’ with beneficial link, from vision to brain and smoking to drinking. It has anti diabetic to anti ageing properties .Taurine is also involved in verities of ways to improve the quality of life to make it more happier and healthier .Some of the taurine analogues also exhibit similarly. Hence taurine such potential require further extension and enlargement but with logistic support. The better prophylaxis of several important diseases will not be possible unless the nutritional quality of the diet can be made much better, than it is often the case as of today, unless we bring the concept of “functional food”, in reality such dream ;”Quality of Life” will be remain a dream. Looking the success of Taurine therapy; combination of both dietary and pharmacological intervention is best suited approach, now it is time for,” tailored functional food” with multifunctional therapeutic intervention, is perhaps only hope; not to Homo sapiens but to all others animals.

A new systems approach to diseased states and wellness result in a new branch in the healthcare services, namely, personalized and precision medicine (PPM). To achieve the implementation of PM concept, it is necessary to create a fundamentally new strategy based upon the subclinical recognition of biopredictors of hidden abnormalities long before the disease clinically manifests itself. Each decision-maker values the impact of their decision to use PPM on their own budget and well-being, which may not necessarily be optimal for society as a whole. It would be extremely useful to integrate data harvesting from different databanks for applications such as prediction and personalization of further treatment to thus provide more tailored measures for the patients resulting in improved patient outcomes, reduced adverse events, and more cost effective use of health care resources. A lack of medical guidelines has been identified by the majority of responders as the predominant barrier for adoption, indicating a need for the development of best practices and guidelines to support the implementation of PPM! Implementation of PPM requires a lot before the current model “physician-patient” could be gradually displaced by a new model “medical advisor-healthy person-at-risk”. This is the reason for developing global scientific, clinical, social, and educational projects in the area of PPM to elicit the content of the new branch.

The main goal of Body Area Network,BANs, and Wearable BANs is to provide continuously biofeedback data to the patient and to the medical center.WBANs can record personal information, electrocardiograms, measure body temperature and blood pressure, measure heartbeat rate, arterial blood pressure and other healthcare parameters in an efficient way. For example, accelerometers can be used to sense heartbeat rate, movement or even muscular activity. Efficient small antennas are crucial in the development of wearable 5G communications and medical systems. Low efficiency is the major disadvantage of small antennas. However, design and production of compact efficient wearable antennas is one of the major challenges in production of wearable communication systems. Low profile compact antennas and transceivers are crucial in the development of wearable BANs and systems. Development of wearable antennas and compact transceivers for communication and biomedical systems will be described in this paper. The main goal of Wireless BANs, WBANs, is to provide continuously medical data to the physician. Meta material and fractal technology are used to improve the efficiency and bandwidth of small antennas. Moreover, the dynamic range and the efficiency of communication system may be improved by using active wearable antennas. Amplifiers may be connected to the wearable antenna feed line to increase the system dynamic range. New wideband passive and active efficient wearable antennas for IOT, BAN and 5G applications are presented in this paper. The gain and directivity of the patch antenna with Split-ring resonators, SRR, is higher by 2.5dB than the patch antenna without SRR. The resonant frequency of the antennas with SRR is lower by 5% to 10% than the antennas without SRR.Active small wearable antennas may be used in receiving or transmitting communication, IOT and medical systems. For example, the active slot antenna gain is 12+2dB for frequencies from 1.25GHz to 3.25GHz.

Fibrous structures comprise a large percentage of engineering materials found in both synthetic and biological composite systems. From a multiscale perspective, one must fully understand mechanical properties at both the molecular scale and the microscale in order to understand the mechanical properties at the composite level. In this presentation, I will discuss some computational and mechanical modeling techniques that can be used to study the behavior of fibrin clots that form in response to vascular injury. These techniques can also be used to study fibrin clots that form in cases of undesired and excessive coagulation. In addition, I will highlight mechanical modeling techniques that have been developed to understand multiscale mechanisms that govern the mechanical behavior of fibrin clots under various loading conditions.

Food is any substance which provides nutritional support for an organism. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrate, fats, proteins, vitamins and minerals which is digested and assimilated to provide energy, growth and maintain life. Food safety is defined as the scientific discipline describing handling, preparation, and storage of food in ways that prevent food-borne illness. The occurrence of two or more cases of a similar illnesses resulting from the ingestion of a common food is known as a food-borne disease outbreak. So, it is a very critical issue to the sustainability of human life on the earth. This issue is currently under threat and facing many challenges. The current challenges facing food safety in Egypt will be discussed which include (but not limited to) changes in our food production and supply, changes in the environment leading to food contamination, the increasing use of pesticides and the possible hazards of carcinogenesis, food poisoning, liver failure and renal failure, the application of genetic engineering in food production, new and emerging bacteria, toxins, and antibiotic resistance and the expansion of food industries and readymade foods. On the other hand, the international efforts taken to confront such challenges will be presented which include the use in natural product in agriculture (bio-fertilizers), the use of natural products in food preservation, the use of natural products in controlling agricultural pest as a substitute for pesticides either during plant life or at postharvest stage, the use of bio-control technology in agriculture, organic and bio-agriculture. and clean agriculture.

Biological materials, as well as industrial composite materials, present very complex structures constituted by various compartments at different scales. Materials having the same constituents can differ in microstructural geometrical arrangement, which can have a significant impact on the overall behavior of the heterogeneous structure. Diverse phenomena observed on the macroscopic scale, such as viscoelastic effects or ability of contraction, originate from processes that are associated with the microstructural level. The macroscopic behavior of heterogeneous materials depends strongly on the spatial distribution, shape and material properties of the microstructural constituents and their interactions. There are different approaches that can be used in mathematical modelling of heterogeneous multi-phase materials, especially biological tissues. The mixture theory, based on the constituent volume fractions, or self-consistent methods are well known and commonly used, but they are applicable only for a limited range of problems with a specific geometry. The so-called micro-continuum methods incorporate material microstructural data into the description by introducing additional degrees of freedom that usually reflect some aspects of the underlying microstructure. In this work, the method of asymptotic homogenization (AHM) is applied to describe the mechanical behavior of soft biological tissues. This approach operates with multiple scales and enables to respect the geometrical arrangement and material constitution of the media on different structural levels. The main advantage of this method is that it provides a general framework that can be relatively easily extended; therefore, it is possible to incorporate new features to the current models.

The theory of acoustic and electromagnetic wave scattering by one and many small impedance particles of arbitrary shapes is developed. The basic assumptions are ad, where a is the characteristic size of particles,d is the smallest distance between the neighboring particles is the wavelength. This theory allows one to give a recipe for creating materials with a desired refraction coecient. One can create material with negative refraction: the group velocity in this material is directed opposite to the phase velocity. One can create a material with a desired wave focusing property. Equation is derived for the EM eld in the medium in which many small impedance particles are embedded. Similar results are obtained in for heat transfer in the media in which many small particles are distributed.

The strategy of price liberalisation and privatisation had been implemented in Sudan over the last decade, and has had a positive result on government deficit. The investment law approved recently has good statements and rules on the above strategy in particular to pharmacy regulations. Under the pressure of the new privatisation policy, the government introduced radical changes in the pharmacy regulations. To improve the effectiveness of the public pharmacy, resources should be switched towards areas of need, reducing inequalities and promoting better health conditions. Medicines are financed either through cost sharing or full private. The role of the private services is significant. A review of reform of financing medicines in Sudan is given in this study. Also, it highlights the current drug supply system in the public sector, which is currently responsibility of the Central Medical Supplies Public Corporation (CMS). In Sudan, the researchers did not identify any rigorous evaluations or quantitative studies about the impact of drug regulations on the quality of medicines and how to protect public health against counterfeit or low quality medicines, although it is practically possible. However, the regulations must be continually evaluated to ensure the public health is protected against by marketing high quality medicines rather than commercial interests, and the drug companies are held accountable for their conduct.

Although TMJ is a synovial joint, there are particularities that physiology can explain for its diagnosis and consequently better treatment is proposed. We cannot propose treatment without knowing how TMJ is normally. In this chapter, we will make a brief review of physiology to make clear the adaptive response of TMJ. The stomatognathic system is a functional neuromuscular system that makes TMJ depending on the physical loads and the force vectors involved in jaw motion. The understanding of physics and human physiology makes us understand better the stomatognathic system. From now on, we can discuss several possibilities of functional surgical treatment Possibilities for surgical treatment:Indication and surgical technique Arthrocentesis Video Arthroscopy - Diagnostic Disc supplementation / PRP Stem cells (Discopexy) Anchorage Ablation and radiofrequency Alloplastic reconstructions / Prostheses (stock and customized)

The issue of corrosion is a well-known problem and it causes the weakening of metal and its properties and makes it unfit for use. Corrosion causes enormous economic losses consistently over years in equipment maintenance, repair, and its substitution. In Gulf Cooperation Council (G.C.C) countries, money spent into corrosion control and repair are extremely dependent on production of oil, refining and petrochemicals sector shall be noteworthy as it comprises more than 33% of gross domestic products. Until now, various coatings have been developed to tackle this problem like sacrificial coatings, barrier coatings, noble metal coatings and electrically resistive coatings. In this study, self-healing smart anti-corrosion coatings were synthesized as it is a much lesser investigated area of research. Functionalized particles from mesoporous carbon along with mesoporous silica etc. were used as Nano containers for encapsulation of corrosion inhibitor for self-healing purpose using layer-by layer (lbl) self-assembly method and their effect on performance of coatings were studied after adding in commercially available polymer matrix against the corrosion of mild carbon steel in seawater. A series of tests were conducted on the resultant coatings to investigate their corrosion resistance, self-healing performance etc. This study will evaluate the protection offered by coatings of commercially available porous materials against the corrosion of mild steel in seawater, along with addition of different encapsulated nano containers in the polymer matrix. Benzotriazole (BTA) was used as a corrosion inhibitor in this study for synthesizing Nano containers. Self-healing smart anti-corrosion coatings, is a much lesser explored area of research with the major challenge of low adhesion properties and release of Nano containers to heal the corroded metal substrate. This calls for preparation of substrate surface and treatment of coatings to establish good interfacial interaction of the nano containers with the porous material and their successful release in the medium upon a pH change to avoid delamination/corrosion of coatings in water. The potential of the functionalized carbon materials to further enhance anticorrosion performance of the self-healing coatings was also evaluated. The coatings were prepared by brush coatings as well as dip-coating methods in determined optimal conditions on clean polished mild carbon steel coupons. The coating degradation behavior and corrosion resistance was investigated by the immersion tests (performed in 3.5 wt. % sodium chloride solution) and Potentiostatic Electrochemical Impedance Spectroscopy (PEIS). Brunauer Emmett Teller (BET) testing was done only initially in order to determine the degree of impregnation in the pores of the carbon and silica materials. Corrosion monitoring was performed using Linear Polarization (LP) technique. Other nanocapsules characteristics were studied using techniques such as Fourier Transform Infrared Spectroscopy (FTIR), X Ray Diffraction (XRD) was used to characterize the composition of the multilayers of the Nano capsules, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) were used to analyze the surface morphology of coatings as well as nanocapsules. The visual appearance of coating and corrosion products was studied using Optical Microscopy (OM). Coating thickness measurements were done using a standard PosiTector gauge. Zeta Potential was also analyzed continuously during the synthesis of nanocapsules in order to optimize the layer-by-layer assembly of a self-healing coating. Ultraviolet visible spectroscopy (UV-Vis) was also studied to analyze the release behavior of the synthesized Corrosion Inhibitor encapsulated Nano containers in different pH of water. Self-healing testing of the synthesized coatings based on ASTM D7027-13 standards was also carried out to analyze the coating performance when exposed to corroding conditions. The electrochemical impedance spectroscopy (EIS) results illustrated the improved corrosion resistance of the coating based on carbon materials. The proposed coating also had a rapid self-healing ability in the presence of water. The mesoporous carbon based coatings produced, were highly stable and protective in nature. The self-healing coatings possessed high impedance good barrier characteristics. The mesoporous carbon and functionalized mesoporous carbon coatings were compared with coatings of mesoporous silica and commercially available vinyl acrylate. The SEM analysis also revealed successful release of BTA onto the corroded surface thus verifying the self-healing effect. UV-Vis predicted that the carbon based capsules had more impregnation of the corrosion inhibitor than the silica based nanocontainers. It was observed that carbon based coatings and its 5 wt. % composition in the polymer matrix had better anticorrosive performance and adhesion than the silica coatings and provided much greater substrate protection as explained in the work in detail.

In recent year, many governments on their E-health national strategies have pledged substantial levels of financial investment for Personal health record ePHRs in health care. The National Program for IT in the UK National Health Service (NHS), led by the agency NHS Connecting for Health, was estimated to cost E12.8 bn. In the US, the Obama administration has committed a US$38 billion for E-health investment. A serious concern is to ensuring a cost-efficient, innovative and high-quality personal health record ePHRs or Summary care report SCR still a massive challenge in both developed and developing countries. This motivates a series of initiatives aimed at more integrated care. And the desirability of integrated services for better healthcare: more patient-centered healthcare delivery - improved resource utilization - better management of information. Consequently, many questions still rising of the slowing implementation and adoption of the ePHRs as a nation-regional wide tool to a better healthcare Management. This study aims to provide insights on the factors, which would influence a patients intention to use an ePHRs system. In particular, will consider the changing role of consumers in managing their health, and the implications of such a role change for ePHRs system use. As such, the study introduces a scoping review and examination of the literature pertaining to the potential of ePHRs systems to support a shift towards consumer based health care. Secondly, presents the theoretical underpinnings of our further research study based on both MIS and Psychology theories in conjunction with the theoretical Health Information Systems HIS Evaluation Framework model. The expected findings will provide several contributions to theory and practice. With respect to benefits to theory, findings of this research will open the gateway to apply the significant body of research on patients motivation and self - determination to the context of ePHRs adoption as well as personal health management. With respect to practice, findings of this research study can inform hospital top managers, industrial developers and Ehealth national decision makers on how to more successfully go about their jobs. In addition, the results can inform health care providers on how to support and facilitate the use of PHR systems for their patients.

Changes in the morphology of a skin lesion is indicative of melanoma, a deadlytype of skin cancer. This talk describes a temporal analysis method to monitor thevascularity, pigmentation, size and other critical morphological attributes of the lesion.Digital images of a skin lesion acquired during follow-up imaging sessions serves as inputto the system. The images are preprocessed to normalize variations introduced over time.The vascularity is modelled as the skin images’ red channel information and its changes bythe Kullback-Leibler (KL) divergence of the probability density function approximation ofhistograms. The pigmentation is quantified as textural energy, changes in the energy andpigment coverage in the lesion. An optical flow field and divergence measure indicates themagnitude and direction of global changes in the lesion. Sub-surface change is predictedbased on the surface skin lesion image with a novel approach. Changes in keymorphological features such as lesions’ shape, color, texture, size, and border regularityare also computed. Future trends of the skin lesion are estimatedvia an auto-regressive predictor.Finally, the classification performance with features extracted using deep convolutionalneural networks and the hand-crafted lesion features are compared. An accuracy of 80.5%,specificity of 98.14%, sensitivity of 76.9% with a deep learning neural network and anaccuracy of 25.17%, sensitivity of 92.31%, specificity of 8.9% with the hand-craftedfeature approach is achieved. Experimental results show the potential of the proposedmethod to monitor a skin lesion in real-time during routine skin exams.

There is a growing demand for technological improvement in healthcare. The electro-active features of biological cells inspires researchers to investigate electronic characteristics of molecular species with the application of electrical fields. The application of electrical fields to stimulate cellular reactions and activate bio-cells to recover from a disorder or disease is one such consideration. Electrical stimulation for disease treatment, has long been known to have an important effect on living creatures. It can influence the cell function by inducing various types of responses which may enhance or inhibit various molecular mechanisms. Therefore, the application of electrical fields and cellular reactions becomes fundamental for developing smart Biomedical Integrated Circuit (IC) solutions for a variety of low power and light-weight biomedical treatment devices that are implanted within the body and for non-invasive devices to improve patients’ lives with no risk. Bioelectronics device technology advancements that use the application of an electrical stimulation to treat chronic diseases made the reliable Nanometer CMOS technology (Complementary Metal-Oxide Semiconductor) for biomedical IC design to medical needs more important and challenging. It can be designed for use as alternative treatments to overcome the deficiencies of several conventional medical treatments. It could potentially assist as drug-free relief to treat terminal diseases when therapeutic drugs become ineffective and cannot be replaced. In this review, the initial focus of the research attempts, is to obtain a fundamental understanding of biomedical IC design and the interface between the electronic signal and the biological materials in order to develop the bio-concept and introduce a biomedical treatment device capable of communicating with electro-active biological cells assisting human health.

Glucose is a key energy supplier and nutrient for tumor growth. Inspired by the glucose oxidase (GOx)-assisted conversion of glucose into gluconic acid and toxic H2O2, a novel treatment paradigm of starving-like therapy is developed for significant tumor-killing effects, more effective than conventional starving therapy by only cutting off the energy supply. Furthermore, the generated acidic H2O2 can oxidize L-Arginine (L-Arg) into NO for enhanced gas therapy. By using hollow mesoporous organosilica nanoparticle (HMON) as a biocompatible/biodegradable nanocarrier for the co-delivery of GOx and L-Arg, a novel glucose-responsive nanomedicine (L-Arg-HMON-GOx) has been for the first time constructed for synergistic cancer starving-like/gas therapy without the need of external excitation, which yields a remarkable H2O2-NO cooperative anticancer effect. Furthermore, in order to promote the effective tumor accumulation of HMON for precise cancer theranostics, the sub-50 nm thioether/phenylene dual-hybridized HMON with low hemolytic effect has been successfully synthesized. Particularly, the surface modification with Mo(VI)-based polyoxometalate (POM) clusters drives the selfassembly of HMON in the mild acidic tumor microenvironment (TME) to achieve enhanced tumor retention and accumulation. Moreover, the reducibility-activated Mo(VI)-to-Mo(V) conversion within POM not only endows the POM-anchored HMON with outstanding TME-responsive photothermal therapy (PTT) performance, but also plays an indispensable role in controllably triggering the decomposition of the Mn2(CO)10 payload for CO release, which gives rise to remarkable synergistic PTT-enhanced CO gas therapy for complete tumor eradication. This smart POM-anchored HMON nanoplatform is expected to act as a “magic bomb” to selectively destroy cancer without damaging normal tissues, promising for clinical translation.

Refractory epileptic patiensts, of all ages and conditions, can have seizures anytime, anywhere. Their daly lives will be enormously improved when transportable (and comfortable) devices will warn them of a coming seizure. There has been an intensive and extensive research to buil such devices. However progresses have been insufficient and research goes on in many places. Deep learning is the most successful and promising machine learning approch. Building classification and decision algorithms to make good predictions and avoid false warnings is an interesting challenge addressed in this presentation. Convolutionl Neural Networks (CNN) and Long Short Term Memory Networks (LSTM) are developed for this purpose. The degrees of freedom of these networks are discussed and used to improve performance in sensitivity and specificity. A set of features, based on the energy content of an intracranel electrode placed in the epileptic focus (where the seizure starts), and the spectral distributions in a set on bands, is used for training and testing the predictors. Results for a set of patients show that these machine learning tools have a strong potential to build algrithms for efective seizure prediction. However a more large study is needed, including a large trial with patients in ambulatory, to find a solution that will be accepted by the clinical community.

Premeltons are examples of emergent structures (i.e., structural solitons) that arise spontaneously in DNA due to the presence of nonlinear excitations in its structure. They are of two kinds: B-B (or A-A) premeltons form at specific DNA-regions to nucleate site-specific DNA melting. These are stationary and, being globally nontopological, undergo breather motions that allow drugs and dyes to intercalate into DNA. B-A (or A-B) premeltons, on the other hand, are mobile, and being globally topological, act as phase-boundaries transforming B- into A- DNA during the structural phase-transition. They are not expected to undergo breather-motions. A key feature of both types of premeltons is the presence of an intermediate structural-form in their central regions (proposed as being a transition-state intermediate in DNA-melting and in the B- to A- transition), which differs from either A- or B- DNA. Called beta-DNA, this is both metastable and hyperflexible and contains an alternating sugar-puckering pattern along the polymer-backbone combined with the partial-unstacking (in its lower energy-forms) of every other base-pair. Beta-DNA is connected to either B- or to A- DNA on either side by boundaries possessing a gradation of nonlinear structural-change, these being called the kink and the antikink regions. The presence of premeltons in DNA leads to a unifying theory to understand much of DNA physical-chemistry and molecular-biology. In particular, premeltons are predicted to define the 5 and 3 ends of genes in naked-DNA and DNA in active-chromatin, this having important implications for understanding physical aspects of the initiation, elongation and termination of RNA-synthesis during transcription. For these and other reasons, the model will be of broader interest to the general audience working in these areas. The model explains a wide variety of data, and carries within it a number of experimental predictions all readily testable as will be described in my talk.

There is increasing evidences that favor the prenatal beginning of schizophrenia. These evidences point toward intra-uterine environmental factors that act specifically during the second pregnancy trimester producing a direct damage of the brain of the fetus . The current available technology doesn't allow observing what is happening at cellular level since the human brain is not exposed to a direct analysis in that stage of the life in subjects at high risk of developing schizophrenia. Methods. In 1977 we began a direct electron microscopic research of the brain of fetuses at high risk from schizophrenic mothers in order to finding differences at cellular level in relation to controls. Results. In these studies we have observed within the nuclei of neurons the presence of complete and incomplete viral particles that reacted in positive form with antibodies to herpes simplex hominis type I [HSV1] virus, and mitochondria alterations . Conclusion. The importance of these findings can have practical applications in the prevention of the illness keeping in mind its direct relation to the aetiology and physiopathology of schizophrenia. A study of the gametes or the amniotic fluid cells in women at risk of having a schizophrenic offspring is considered. Of being observed the same alterations that those observed previously in the cells of the brain of the studied foetuses, it would intend to these women in risk of having a schizophrenia descendant, previous information of the results, the voluntary medical interruption of the pregnancy or an early anti HSV1 viral treatment as preventive measure of the later development of the illness.

Cervical cancer is the major cancer affecting men and is growing at a very significant rate. One of the major challenges in treatment of cervical cancer is its detection in early stages. The use of Cervical Specific Antigen (CSA) testing has aided the prediction of cervical cancer. The most widespread techniques for detecting cervical cancer are based on the enzyme-linked immune sorbent assay (ELISA). Recently, bio molecule sensors based on quasi one dimensional semiconductor nanostructures like nanotubes, nanowires and nanobelts have attracted considerable attention because of their distinct electrical, optical and magnetic properties. Hence, here we analyze the device properties of Carbon Nano Tubes (CNT) such as mechanical properties, optical and electrical properties and its relevance as cervical cancer detector or CSA detector. The comparison of MOSFET inverter with CNTFET is also carried out and found that CNTFET has same performance as that of MOSFET with less complexity. Carbon nanotubes have many properties, from their unique dimensions to an unusual current conduction mechanism that make them ideal components of electrical circuits. Currently, there is no reliable way to arrange carbon nanotubes into a circuit. CNTFETs with sub-100 nm channel length could be fabricated by means of electron beam lithography. The precision of the Stanford model can be explained by the several non-idealities assimilated such as scattering, effects of the doped source/drain extension region, Schottky barrier resistance and inter-CNT charge screening effects. The quasi-ID device structure gives better gate electrostatics control over the gate region. Increasing the number of CNTs per device is the most effective way to improve the on current. The cervical cancer cells detection at early stage by this CNTFET bio-sensor is noel approach.

Following the rising cases of high hospitalization versa-vise incessant fatality rates and the close affinity of listeria with HIV/AIDS infection, which often emanates from food-borne pathogens associated with listeriosis monocytogenes infection, this present paper seek and formulated as penultimate model, a set of 8-Dimensional classical mathematical equations that directly accounted for the biological interplay of dual listeriosis virions with dual set of population (human and animals) studied under multiple chemotherapies (trimethoprim-sulphamethoxazole with a combination of either penicillin or ampicillin and/or gentamicin). Using ODEs, the positivity and boundedness of system solution was investigated and model presented as an optimal control problem. In the analysis that follows, the study explored classical Pontryagins Maximum Principle with which the model optimality control system as well as existence and uniqueness of the control system were established. In correlating the derivedmodel with clinical implications, numerical validity of the model was conducted. Results indicated that under cogent and adherent to specify multiple chemotherapies, maximal recovery of both human and animal infected population was tremendously achieved with consequent rapid decline to near zero infection growth. The study therefore suggests further articulation of more chemotherapies and early application at onset of infection for a visible elimination of listeriosis infection.A possibility geared towards the advancement of biomedicalengineering.

A simple and non-invasive medical diagnosis for anemia defect is presented in this paper . Anemia defects is relevant to the deficiency of haemoglobin in human. This approach utilizes photographic images of human nail for the anemia defect diagnosis. This method extracts the nail region in an effective approach by appropriate color conversion, background elimination, segmentation by connected components by fixing the threshold value and finally extraction of nail region is attained. The above procedures ensure the extraction of region of interest accurately instead of cropping the nail region. Then RGB color analysis is applied for the nail region by estimating the statistical parameter of each nail. This values and haemoglobin levels of patients obtained from hospitals are compared with each other for the accuracy of the anemia defects. In this work, the haemoglobin level of patients received from the hospitals matched with the parameter values of the nail image of the person while comparing the results. Hence this method is simple, accurate, non-invasive and cost effective in diagnosing anemic status of patients in an earlier stage which is easy to achieve prevention of disease rather than cure.
