A sixty-year-old woman with no remarkable systemic disease came to our clinic due to blurred vision of right eye for one month. The best corrected visual acuity (BCVA) was 0.2 in the right eye, while intraocular pressure, anterior segment, and optic disc of right eye were all normal. Optical coherence tomography (OCT) was arranged, which showed VMT in right eye.

Bioavailability in different formulations of desvenlafaxine100 mg prolonged-release tablets was compared in two bioequivalence studies, one under fasting conditions and the other after a standard breakfast. Both studies were a single dose, randomized, open-label, two-period crossover, with Brazilian male and female healthy subjects. Blood samples were taken during 48 h and plasmatic concentrations were determined using a validated UPLC-MS/MS method.

The de-extinction of the dinosaur is a dubious possibility but its consideration brings forth some issues that are at least worthy of scientific discussion. In this review, we discuss two distinct issues that have implications for a de-extinct species such as a dinosaur: the ability, or lack thereof, to safely sedate a rare and potentially fractious animal capable of harming the veterinary staff tasked with its care; and, disease risks associated with a species that has been extinct for millions of years. To identify potential sedatives, comparative pharmacology will be needed to uncover the links between receptor pharmacology and the desired clinical outcomes of activating established alpha-2 adrenergic, opioid, and benzodiazepine receptors. Specific to disease control, it will be necessary to understand the unique susceptibility of the new species to current diseases as well as predicting their reservoir capacity for potential human and veterinary pandemic diseases. While the topics presented herein are not exhaustive, this review highlights some of the foremost research that should be conducted in order to serve the unique veterinary needs of a de-extinct species using the dinosaur as a paradigm. Addressing these issues should be considered if an intact dinosaur genome becomes available, regardless of the feasibility of dinosaur resurrection.

Pressure head was gained from the distribution of pores to characterize the sandstones of the Shajara reservoirs of the permo-Carboniferous Shajara Formation. The attained values of pressure head were employed to calculate the pressure head fractal dimension. Based on field observations in addition to the acquired values of the pressure head fractal dimension, the sandstones of Shajara reservoirs were divided here into three units. The obtained units from base to top are: Lower Shajara Pressure Head Fractal Dimension Unit, Middle Shajara Pressure Head Fractal Dimension Unit and Upper Shajara Pressure Head Fractal Dimension Unit.

Cerebral amyloid angiopathy (CAA) is frequently associated to Alzheimer’s disease (AD) but can also occur in Lewy body dementia (LBD). The present post-mortem study compares the incidence and the topographic distribution of small cerebrovascular lesions in LBD brains without and with severe CAA (LBD-CAA).

A field experiment was conducted at Farmer’s field in Banepa, Kavreplanchowk District during the spring season, 2015 to find out the optimum plant spacing on cauliflower production. Four plant spacing viz. (i) 45×45 cm in single row spacing, (ii) 52.5×45 cm in double row spacing, (iii) 52.5×30 cm single row spacing and iv) 52.5×30 cm in double row spacing were included in the study

The side effects of spinal anesthesia have been the focus of many researchers. These complications can affect patients’ satisfaction following surgery and duration of hospitalization. Therefore, factors that lead to increased risk of side effects must be identified, one of these factors is gender. This study evaluated the relationship between gender and adverse effects after spinal anesthesia.

Gemcitabine is a pyrimidine analog and cisplatin is a platinum agent, they are usually combined to form a chemotherapeutic doublet used to treat different types of oncological cancers, including non-small cell lung cancer (NSCLC). Although these agents are not known to cause such events, few cases related to possible cardiotoxicity side effects have been reported ; including angina, chronic heart failure, arrhythmias, and cardiac ischemia. A 52-year-old African male presented with Stage IV lung adenocarcinoma metastatic to the bone, pleura and lymph node, EGFR wild type. Patient has a history of hypertension, diabetes, and atrial fibrillation and on rate control medications. He was treated initially with cisplatin-gemcitabine, after which he developed cardiomyopathy.

MicroRNAs (miRNA) are potent regulators, controlling multiple biological processes, including cell growth, differentiation, cell death, development and immune responses. With emerging data supporting that miRNAs play a central role in gene dysregulation in human malignancies, unraveling the miRNA genetic variations in cancer is essential and critical if we want to develop better diagnostic and prognostic system for our patients.

Joint endoprosthesis are standard treatment in orthopedic surgery, but the risk of infection represents a major drawback for elderly patients with comorbidities. Therefore, we investigated joint endoprosthesis infections in Germany (2005-2012) focusing on elderly patients. We extrapolated infection related costs to estimate the burden for the health care system.

The removal of pesticides in the environment mainly depends on natural degradation, especially on microbial degradation. Biodegradation has many advantages, such as complete degradation, no secondary pollution, quick effect and wide spectrum. Based on the single-factor experiments and Box-Benhnken design, the effect of four factors on the degradation of chlorpyrifos by P. stutzeri ZH-1 was investigated.

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.

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.
