In the past, finding out the chemical resistance of the barrier materials designated for the production of individual protective equipment ofthe protection forces (policemen, firefighters, soldiers) was based on the need to respond to protection against weapons of mass destruction. Simple chemical methods based on indicating the colorimetric reactions were used. It was necessary to switch to more universal methods due to a change in the security of the environment and the need to focus on toxic industrial materials. The universality is due to using sensitive QCM sensors equipped with a special detection layer and some special carbon electrodes. The paper deals with new methods that are used to determine the chemical resistance of the barrier materials against the permeation of toxic substances, primarily in field conditions. However, they can also be used in stationary chemical laboratory conditions.
Background and aim. Adverse drug reactions (ADRs) are common events in medical practice, representing a matter of concern for both outpatient and in hospital care. Understanding and management of ADRs depend on their mechanism and clinical picture, which are complex and highly heterogeneous. Drug hypersensitivity reactions (DHRs) are immunologically-mediated ADRs, which are considered allergies after demonstrating evidence of either drug-specific antibodies or T-cells. The correct diagnosis of a drug allergy in hospital setting is essential for the outcome of treated disease and for the patient future in terms of therapeutic needs. Patients may be labeled as being drug allergic, based on their history and vague symptoms that do not correspond to a true allergic reaction. The aim of our study was to evaluate consequences of drug allergy labelling of female patients hospitalized in the department of obstetrics and gynecology from a university hospital during one year, in terms of medical attitude and therapeutic approach. Method and Results. We found that 159 out of 2395 patients hospitalized in the obstetrics-gynecology department declared a history of drug allergy on admission, but only 3 patients had medical documents and adequate recommendations from the allergist. Hospital medical attitude was significantly influenced in all declared allergic patients, mainly in terms of antimicrobial and anti-inflammatory therapy. Conclusion. We concluded that overestimation of drug allergies in hospital care has important consequences in terms of current and future recommended therapy that should be based on standardized allergist evaluation.
Background: Gait analysis is receiving increasing attention due to various applications in athletic performance, man-machine interfaces and especially in military services. This analysis involves the analysis of human locomotion augmented by body movements and biomechanics of joints. The kinematic motion of the body during a gait cycle capturing by cameras is then used as the desired target for modelling the motion of body segments. By taking advantage of gait analysis concept, this study aims to model the military marching, using anthropometric data with the focus on lower limbs while introducing top candidates with better healthy conditions in lower limb joints during a cycle of marching. Methods: Using 100 anthropometric data from military soldiers, equations of motion for the model are derived by applying Lagrangian methods in an inverse dynamic approach. In this model, the joints are simulated using springs and dampers while the actuators, simulated the muscles, acted like motors and applied enough torque on joints so that the model motion replicates normal military marching. Finally, all the springs and dampers coefficients are driven from optimization process. Results: Hip, knee and ankle torques were calculated after the optimization process for all 100 soldiers and then 5 candidates among them were established with less suffering forces and torques in their joints. Conclusions: In this study using biomechanics basics and anthropometry data at the same time, a standard could be evaluated to select the soldiers based on healthy condition of lower organs.
The increasing of the modern technologies requires the setting up of multiple factories and industries that produce smokes and chemicals, which polluted the air, water, and the environment resulting in putting lives in dreaded conditions. In fact, the coming of the modern era and the modern lifestyle gives birth to numerous deadly diseases like cancer and its related diseases, which increasingly takes the lives of many in the country. The cold-blooded killer ‘cancer’ becomes the major public health concern in India as a whole. Among all the problems existed across the world, the problems or the issues associated with cancer or terminal illness becomes the worldwide phenomenon that produces several unwanted worst experiences. Human polluting the water, soil, and the air continued, and the global burden of cancer affected populations rapidly increasing year after year. Unfortunately, India turns out to be the world most densely cancer populated regions and a cancer hub. The reason behind the rapidly increasing of cancer illness and its mortality rates in India is mainly due to people lack awareness on cancerous factors, no proper preventive measures, and the late detection of the symptoms at the advanced stages when cure is not possible.Thus, concerning the helplessness conditions of the cancer effected people of in general, the current analytical study has been forms with an aim to spread awareness on the cold-blooded killer cancer across the country.

Background and Aim: The CCHF (Crimean-Congo hemorrhagic fever) virus causes a severe disease in human with a case fatality rate of up to 50%. Since, there is no specific treatment or approved vaccine against CCHF viral infections, an accurate and early detection as well as a reliable surveillance and quantitative determination of viral load is necessary for patient improvement and case management. In this research, our aim was to develop a probe based one-step real- time reverse-transcription polymerase chain reaction (rRT-PCR) assay for in-house quantitative detection of CCHF virus. Methods: At first, the highly conserved S-fragment sequence of CCHF virus genome was adapted from GenBank and the specific probe and primers targeting this region were designed. Then, viral RNAs were extracted from 37 blood samples of different patients from east of Iran (Zahedan). The specificity and sensitivity of the probe and primers were also evaluated in positive blood samples, confirmed to have CCHF virus. A standard (PTG19-T vector containing S-fragment) for quantization was also constructed and the viral load was determined in some of positive samples. Results: From a total of 37 suspicious blood samples, 15 samples were confirmed to be positive for CCHF virus by this probe based one-step rRT-PCR assay and no false-positive result was detected according to sequencing data. The predicted fragment of 176 bp was also confirmed in all positive samples by gel-based electrophoresis analysis. The assay was linear between 10 to 103 copy numbers per each microliter of extracted plasmid for this technique and the viral load determined in one of patient blood samples was 55,000 viral particles per each milliliter, for example. Bioinformatics and experimental evaluations approved the specificity of this assay. The LOD of the assay was 10 (or fewer) copy numbers of viral genome per each microliter of the extracted genome. Conclusions: This research showed that the developed probe based one-step rRT-PCR assay is a specific, rapid, sensitive and the simple tool for detection and viral load determination of the CCHF virus.

Introduction – With increasing life expectancy and changing trends in diseases, lifestyle diseases come forward and become a major concern. Ischemic stroke is an emerging public health issue leading to significant morbidity and mortality. To improvise positive outcome in acute ischemic stroke (AIS) and optimizing healthcare resources, accurate and timed prognostication of functional outcome is important. Various studies implied derangement of Hypothalamo- pituitary-thyroid (HPT) axis in AIS, thereby advocates neuroprotective properties to these hormones. This is, still, an open field for active research. Thyroid hormones can, therefore, be used as a surrogate tool for outcome predilection in AIS. This prospective observational cohort study aimed to investigate the alteration of levels of thyroid hormones in AIS and simultaneously correlate their levels in assessment of clinical severity and predicting the functional outcome. Materials and methods – We had collected data from 60 patients of, radiologically confirmed new cases of AIS who sought medical help within 72 hours of initiation of stroke symptom and had no previous history of thyroid disease. Blood samples for thyroid function test [TSH, FreeT3 (FT3), and FreeT4 (FT4)] were collected within 24 hours after admission and subsequently at 7th and 30th day of discharge .On admission neurological clinical severity was assessed by using National Institute of Health Stroke Scale (NIHSS). Functional outcome was assessed by Modified Rankin Scale (mRS) at 7th and 30th day of discharge. Result – Out of 60 AIS patients, 40 were having Non thyroidal illness Syndrome (NTIS). Low T3 was most common NTIS observed. Negative correlation was observed between FT3 levels and on admission NIHSS score and mRS score on follow up. Conclusion – This study thereby concludes that low T3 levels were associated with clinical severity and poor functional outcome in AIS.
Of the major threats to contemporary mankind, is the use of very dangerous and lethal biological agents as the biological weapons. The first step in confronting with this serious threat after prevention, is the accurate and rapid detection of this agents and neutralization of them. In this article, the role of molecules known as aptamer, has been studied in biological defense against these menacing biological agents. Traditional methods for detection of these agents are based primarily on immuno-affinity assays and the use of antibody molecules. While the modern methods, based on aptamer-affinity assays, are being replaced with traditional methods, due to the abundant advantages of them. The selection and preparation method of specific aptamer with high binding affinity to these biological agents is known as SELEX and the use of magnetic nanoparticles to perform this procedure (Mag-SELEX) is very common. The isolated aptamers with high specificity can also be used in neutralization and inhibition of menacing agents function, in addition to, quick and accurate diagnosis of these agents, utilizing them in nano-biosensors, based on aptamers (as the nano- aptasensors).
Background Left ventricular ejection fraction (LVEF), the single most important metric in cardiology, is the cornerstone on which prognosis is estimated and costly decisions such as whether to implant an ICD are based. LVEF is most often assessed by 2D echocardiography (2DE), although 3D echocardiography (3DE) has been shown repeatedly to be more accurate. Aim of the study. We set out to assess whether using 3DE would reclassify the severity of LV impairment in patients with LVEF < 35% by 2DE. Setting. Tertiary cardiac centre serving a population of one million, and performing approximately 100 ICD implants/year. Methods. Successive patients in sinus rhythm, with good endocardial border definition and LVEF<35% by 2D Simpson’s method, had scans according to the BSE protocol. 3D loops were acquired from the apical 4-chamber view and were analysed off-line using for regional wall motion abnormalities (RWMAs) and LVEF. The patients were classified in subgroups according to EF value: less than 20%, 20-25%, 25-30%, 35% and more than 35%. Moderate LV systolic was defined as LVEF between 35% and 45% and severe as LVEF ≤35%. Results. We studied 100 patients (78 M, mean age (SD) 69.94 (13.54) years). 2DE had been requested for decision-making regarding ICD implantation in 86 patients (86%) and for LVEF measurement after acute coronary syndromes in 14 patients (14%). Regional wall motion abnormalities (RWMAs) were present in half of patients (55%, 51 pts – 56% in LAD territory, 31% in RCA/CX territory and 12% multiple territories). 3D LVEF regrouped 67% of patients: 10% to a lower EF and 57% to a higher EF subgroup. Twenty nine patients (29%) were reclassified from severe LV systolic dysfunction by to 2DE to moderate LV systolic dysfunction by 3DE. Patients with RWMAs were more often reclassified than patients without RWMAs (p=0.006). The LV dimensions were lower for the reclassified patients. The image quality had no effect on reclassification. Conclusion Measuring LVEF by 3DE reclassifies the severity of LV systolic impairment in a substantial proportion of patients with 2D LVEF<35% and RWMAs, which may have important clinical and financial implications by resetting thresholds for costly interventions such as ICD implants.
