Quantitative Analysis of Candida Cell Wall Components by Flow Cytometry with Triple-Fluorescence Staining
Detailed analysis of dynamic fungal cell wall components is crucial to our understanding of fungal systematics and the biology and physiology of fungal growth. In fungal pathogens this is of particular importance in examining their response to stress. However, current methodologies do not permit fast and accurate or quantitative analysis of cell wall carbohydrate components. Here, we provide a novel method permitting simultaneous quantitative analysis of the major cell wall components of Candida species relying on triple-staining with fluorescent labeling of chitin, β-glucans and mannans.
A Study on Perceived Stress among Undergraduate Medical Students of Bahir Dar University, Bahir Bar, North West Ethiopia, 2016: Institutional Based Cross Sectional Study
Tertiary education has always been regarded as highly stressful environment to students. Medical and health science training further add to the already stressful environment. Awareness of the existence of stress in medical students by physicians will help in diminishing student’s experience of stress. Therefore, identifying additional stressors in the clinical context is very crucial for providing measures to minimize students’ stress to a tolerable level and helping them to cope better. And the aim of this study is to assess perceived stress and factors associated with it among Bahir Dar University medical students, North West Ethiopia, 2016.
Validation of an Anti-Protective Antigen ELISA for Quantitative IgG Evaluation in B. anthracis Immunized Horses
The potency test for anthrax vaccines has historically involved the challenge of actively or passively immunized laboratory animals with a fully virulent strain of Bacillus anthracis. Lethal challenge studies with the archetypal virulent strains such as B. anthracis Ames strain present considerable difficulties in laboratory management and handling and are too inefficient for the early evaluation of alternative preventative and therapeutic interventions. An ELISA for the evaluation of antibody response to protective antigen (PA) in horses immunized with the Sterne 34F2 strain spore vaccine was developed. The objective of this work was to study the performance of this assay in terms of the guidelines set forth by the International Conference on Harmonics (ICH) and the Center for Biologics Evaluation and Research (CBER) for analytical procedures. We have demonstrated a working range for this assay (73-1581 EU/ml) on the bases of the following parameters: linearity (25 and 1,662 EU/ml, r2 = 0.9988, p < 0.001), accuracy (94.8 - 105.4 %, recovery within the range of 25 and 1,662 EU/ml), precision (≤ 17.6 % CV, repeatability; ≤ 15.7 and ≤ 13.1 % CV, intermediate precision per day and per analyst, respectively), limit of detection (2.25 EU/ml) and limit of quantitation (25 EU/ml). The assay was also demonstrated to be specific for the evaluation of anti-PA IgG antibodies. Based on the assay performance characteristics it was determined that the assay was adequate for use in B. anthracis immunogenicity testing in horses.
Macrocystis of the Lung in a Preterm Neonate: Case Report
Thoracic ultrasonography has been used to evaluate pulmonary parenchyma and the macrocystis of the lung in a preterm with congenital cystic adenomatoid malformation type I. The images gained have been important for diagnosis and therapeutic strategies in our case. An infant was prematurely born with congenital cystic adenomatoid malformation type I. The chest X-ray and computerized tomography showed a great opaque area in the entire right lung, we considered performing a pneumonectomy. This opaque area hampered the expansion of left lung. After draining the macrocystis by ultrasonography-guided puncture, it was possible considering and performing the lobectomy due to the reduction of the volume of macrocystis. During follow up at 4 months, the infant did not show complications and the chest X-ray revealed the reduction of volume of the dense area in parenchyma of right lung.

Wildlife Forensic: Current Techniques and their limitations
The wildlife includes undomesticated and diverse forms of floral and faunal species, which is essential for ecological balance and human survival. The poaching and illegal trade has resulted in sharp decline of many wild species of flora and fauna around the world. The need of the time therefore is to utterly focus on wildlife protection for the sustainable development of biosphere and future viability of human beings. In this review we have focused on different techniques being utilized in wildlife forensic science for identification of wildlife species as well as their geographical origin. These techniques can be employed to control the wildlife crimes and convict the criminals involved in illegal trade of wildlife flora, fauna and their products. These techniques include footprints analyses, morphological and anatomical studies,
Evaluation of Apolipoprotein E Fragmentation as a Biomarker for Alzheimer’s Disease
Recent studies have supported a role for the proteolytic cleavage of apolipoprotein E4 (APOE4) as a potential mechanism for the enhanced dementia risk associated with Alzheimer’s disease. To determine whether APOE4 fragmentation is correlated with AD, ELISA assays were performed with cerebral spinal fluid (CSF) and plasma samples utilizing an antibody that specifically detects a 17 kDa amino-terminal fragment (p17) of APOE (nApoECF antibody). In CSF samples, levels of APOE fragmentation were minimal in both neuropathological normals (NPNs) and AD cases and there were no significant differences between the two cohorts across APOE genotypes.

Splenic Injury after Screening Colonoscopy; Could that Happen Twice? An Unusual Case Report
Iatrogenic splenic injury is a known but rare complication of colonoscopic procedures. Our department describes a very interesting case of the same complication that occurred twice on the same patient. The patient had an elective colonoscopy for microcytic anemia and shortly after the endoscopic procedure she developed excessive abdominal pain and had a syncope episode. She gradually became hemodynamically unstable and needed proper resuscitation. An abdominal tomography scan performed which surprisingly demonstrated active intra-abdominal bleeding pointing a ruptured spleen as the source of the hemorrhage. This finding surprised us given the fact that her past surgical history included a previous splenectomy for the same complication 14 years ago.

Infective Endocarditis at Tricuspid Valve in CHD: What are its Characteristics? What is the Pathophysiology?
Infective endocarditis (IE) is a serious infectious disease that carries a high mortality rate. We report the case of 74-year-old female who is a chronic hemodialysis patient, and was presented with tricuspid valve endocarditis (TVIE) with central venous catheter, due to an Enterobacter Cloacae, which is a non-HACEK Gram-negative bacilli (GNB) and has been reported to be an extremely rare pathogen of IE. The patient was treated with imipenem and teicoplanin for a four-week period, with negative Blood culture and normal C reactive protein (CRP) levels at the end. The aim of our study is to understand the pathophysiology of the IE in chronic renal failure (CRF) especially at the tricuspid valve (TV), and to determine the clinical, biological characteristics and therapeutic modalities.

Recent Developments in Human Odor Detection Technologies
Human odor detection technologies have drawn attention due to the wide possibility of potential applications they open up in areas such as biometrics, criminal investigation and forensics, search for survivors under rubble, and security checkpoint screening. Gas chromatography/mass spectrometry (GC/MS) has been the most successful and powerful analytical approach developed to date for human odor analysis, and hundreds of human odorants have been identified using this tool.
Electronic-nose Applications in Forensic Science and for Analysis of Volatile Biomarkers in the Human Breath
The application of electronic-nose (E-nose) technologies in forensic science is a recent new development following a long history of progress in the development of diverse applications in the related biomedical and pharmaceutical fields. Data from forensic analyses must satisfy the needs and requirements of both the scientific and legal communities. The type of data collected from electronic-nose devices provides a means of identifying specific types of information about the chemical nature of evidentiary objects and samples under investigation using aroma signature profiles of complex gaseous mixtures containing volatile organic compounds (VOCs) released from manufactured products and parts of the human body. E-nose analyses also provide useful qualitative information about the physicochemical characteristics and metabolic conditions of human subjects without the need for time-consuming analyses to identify all chemical components in human-derived volatile mixtures.

polyester, rayon and wool.
The Effects of the Film Thickness and Roughness in the Anodization Process of Very Thin Aluminum Films
The anodization of aluminum foils having micrometer thickness is a common process and results in hexagonally self-ordered alumina membranes. However, anodic aluminum oxide (AAO) membranes fabricated from nanometer-thin films present new challenges to the anodization process, since aluminum films adheres poorly on supporting substrates and the smoothness of the film is highly related to the kind of substrate.
Anodic Oxidation of Titanium in Sulphuric Acid and Phosphoric Acid Electrolytes
Anodisation of pure titanium has been carried out in sulphuric and in phosphoric acid solutions at potentials ranging from 50 to 150V. The SEM and AFM morphological analysis indicates that, within this potential range, oxidation in sulphuric acid solution produces better developed mesoporous oxide layers.
