Education Research: The Neurohumanities in Training: Integrating a Humanities Curriculum Within Neurology Residency Programs.

Background And Objectives: Perhaps stemming from the central role of detailed examinations and a focus on the subjective sphere that grounds their clinical practice, neurologists have frequently opined on experiences traditionally a province of humanities. The increasingly technological focus on medical education and care can be seen to devalue the subjective aspects of medicine. As a counter to this, we report on the existence of neurohumanities curricula within neurology residency training.

Folic Acid-Functionalized Albumin/Graphene Oxide Nanocomposite to Simultaneously Deliver Curcumin and 5-Fluorouracil into Human Colorectal Cancer Cells: An Study.

Background: Nowadays, due to various inherent properties, graphene-based nanoparticles are widely used in drug delivery research. On the other hand, folate receptors are highly expressed on the surface of human tumor cells. In this work, to enhance the 5-fluorouracil (5FU) and curcumin (Cur) effects on colon cancer, we constructed a folic acid- (FA-) modified codelivery carrier based on graphene nanoparticles (GO-Alb-Cur-FA-5FU).

Mediation of arsenic mobility by organic matter in mining-impacted sediment from sub-Arctic lakes: implications for environmental monitoring in a warming climate.

Unlabelled: Arsenic (As) is commonly sequestered at the sediment-water interface (SWI) in mining-impacted lakes through adsorption and/or co-precipitation with authigenic iron (Fe)-(oxy)hydroxides or sulfides. The results of this study demonstrate that the accumulation of organic matter (OM) in near-surface sediments also influences the mobility and fate of As in sub-Arctic lakes. Sediment gravity cores, sediment grab samples, and porewaters were collected from three lakes downstream of the former Tundra gold mine, Northwest Territories, Canada.

Assessment of sexual hormones in foundry workers exposed to heat stress and electromagnetic fields.

The presence of hazardous agents in workplaces has raised concerns regarding their possible impacts on male reproductive system. The present study investigated the individual and combined effects of exposure to heat stress and electromagnetic fields with low-frequency characteristics on the levels of sex hormones in two foundry sections (Aluminum and Cast Iron) of an automobile parts manufacturing plant. The level of workers' exposure (n = 110) to each of the mentioned stressors, was measured through standard methods and for each person and the time-weighted average (TWA) of exposure was calculated.

Relationship between exposure to Extremely Low-Frequency (ELF) magnetic field and the level of some reproductive hormones among power plant workers.

Background And Aims: Today, human beings are exposed to the ELF magnetic field of electrical equipment and power lines, which can damage Leydig cells and alter the secretion of reproductive hormones. The purpose of this study was to investigate the relationship between exposure to ELF magnetic field and the level of some reproductive hormones in male power plant workers.

Materials And Methods: The present cross-sectional study was carried out among all male employees of different units of the selected power plant around Tehran, Iran.

Tunable strong circular dichroism in a non-chiral metallic metasurface integrated with graphene.

In this paper, we propose a non-chiral metasurface using an array of V-shaped silver nanostructures surrounded by two graphene sheets to obtain a tunable strong circular dichroism. The position of peaks and dips in the dichroism spectrum depends on the Fermi energy of graphene and can be tuned by changing Fermi energy. For Fermi energies larger than a specific value, stronger tunable circular dichroism is observed.

Extramedullary hematopoiesis associated with organizing peritoneal hemorrhage: a report of 5 cases in patients presenting with primary gynecologic disorders.

Extramedullary hematopoiesis (EMH) usually occurs in patients with severe anemia or myelofibrosis, and involvement of the serous cavities is uncommon. A total of 5 cases of peritoneal EMH are presented in patients presenting with primary gynecologic pathology including endometrial adenosarcoma (n=2), ovarian leiomyosarcoma, and ovarian endometrioid adenocarcinoma (each n=1), all of which were associated with peritoneal metastases; the remaining patient had a hemorrhagic benign ovarian cyst. All cases were associated with organizing peritoneal hemorrhage, and EMH was localized to the reactive granulation tissue.

Determination of MDMA and its three metabolites in the rat perfused liver.

3,4-Methylenedioxymethamphetamine (MDMA) is one of the most commonly abused illicit drugs in the world. We developed a rapid and simple high-performance liquid chromatography with a fluorescence (FL) detector method to determine MDMA and its metabolites, such as 3,4-methylenedioxyamphetamine (MDA), 4-hydroxy-3-methoxyamphetamine (HMA) and its main unstable metabolite 3,4-dihydroxymethamphetamine (HHMA) besides the internal standards, in a perfusion medium. The separation of analytes was performed at 25°C on a Chromolith® C18 (100 × 4.

Production of chlorogenic acid in Varthemia persica DC (var. persica) callus cultures.

Chlorogenic acid, a pharmacologically important compound, is a phenolic compound that occurs in certain commonly used medicinal herbs. We looked for the presence of this compound in the callus cultures of Varthemia persica DC (var. persica).

Mutation spectra of the AAAS gene in Iranian families with Allgrove Syndrome.

Background And Aims: Allgrove (OMIM#231550) or Triple-A syndrome is a rare, autosomal recessive disorder characterized by the triad of familial adrenal insufficiency, achalasia, and alacrima. Approximately one-half of all patients with Triple-A syndrome have been shown to have mutations in the AAAS gene on chromosome 12q13, which results in loss or non-function of the encoded protein.

Methods: Five unrelated families clinically diagnosed with Allgrove Syndrome were evaluated for sequence variations in the AAAS gene.
