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.

Design of the paper is on the line of combining different knowledge in one space and separating the communicative aspects. The goal of the article is to present a multilevel spacetime model to combine uncertainties to the form of information that gives new possibilities for social interaction and personal growth and development. The study limited itself with studies in three fields-mathematics (AI, number enneagram structures), sociology and world development (interactions visualized with graphs).

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.

Objective: To evaluate the functional mobility of chronic hemiparesis sufferers who undergo 12 weeks of GPCT. IntroductionMethod: We selected 10 chronic hemiparetic patients, aged 21 or over with a medical referral and one-sided hemiparesis with an injury time of ≥12months, capable of walking with or without help and having the ability to perform walking tests. Interviews to collect personal data were conducted, which were then evaluated by Time up & go (TUG) which recorded the time taken for the patient to stand up from a chair, walk 3 meters, return and sit constituting the initial assessment (AV1) and after 12 weeks of intervention with GPCT the final evaluations were taken (AV2).

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.

We investigated the histopathological changes observed in the brains, organs, and apoptotic changes in the brain of young rats born from rats with torsio uteri that survive. We divided 10 Sprague-Dawley rats with a gestational age of 18-19 days into two groups. The rats in group 1 (i.e., the control group; n=5) were given anesthesia only; the rats in group 2 (study group; n=5) underwent a 360-degree clockwise torsion in their uterus, and the torsion was corrected after 6 hours. The births of the offspring were followed, and 7 female and male offspring 1 month of age were selected in each group. The vaginal openings of the young female offspring were checked to determine the time to reach puberty. The 1-month-old male offspring and the mature young female rats were then decapitated. Tissue samples, including visceral organs, genital organs, and brains, were evaluated by histapathologically; we also investigated apoptosis via the TUNEL method. Although no abortion was observed in any of the pregnant rats in the control group, two abortions were observed in the study group after torsion/detorsion.

A cross- sectional study was conducted to assess the nutritional status of the children with rickets aged <5 years at District Headquarter Hospital, Upper Dir in which 50 children were included 33 (66%) male and 17 (34%) female. The study included anthropometric measurement (weight, height and head circumference), clinical presentation, radiographic findings, biochemical assessments, dietary status and information about exposure to sun. clinical results reveal that all children were having one or more clinical signs and symptoms of nutritional rickets including rachitic rosary (14%), widely open anterior fontanel (22%), widening of wrist (14%), bowing of legs (14%), chest infection (22%), diarrhea (10%), delayed eruption of teeth (24%), failure to thrive (10%), fits (4%), sweating (26%) and irritability (20%).

In their first full report on the analysis of GSR by SEM-EDS, Wolten and colleagues stated that the great majority of the gunshot residue particles (GSR), between 70 to 100%, have a characteristic morphology thus providing a detection criterion holding significance equal to that provided by the elemental composition. In fact, the particles must have a spherical or spheroidal shape and their surface should appear amorphous, devoid of any crystalline characteristic.

Autonomic nervous system involvement in subjects practicing Yoga has rarely been studied and has shown conflicting results. Our main purpose was to assess the effect of Yoga on autonomic function of group of subjects practicing Yoga regularly in comparison with another group with normal control subjects by measuring the frequency gain response of the two groups. Other aim of this study was to determine wither the duration of Yoga practicing correlated with measures of heart rate variability signal (HRV) using approximate entropy index (ApEn).

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.

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 aluminum oxide doped with vanadyl citrate chelate complex anions was formed by a two-step self-organized anodization in 2 wt. % sulfuric acid containing 0.04 M V2O5 and 0.08 M citric acid at voltage range 13-23 V, and at 0 and 15 oC. The combination of two temperatures and at least four voltages (depending on the applied temperature) was applied as the operating conditions of anodization.
