Extracellular vesicles (EVs) are cell-derived vesicles present in body fluids that play an essential role in various cellular processes, such as intercellular communication, inflammation, cellular homeostasis, survival, transport, and regeneration. Their isolation and analysis from body fluids have a great clinical potential to provide information on a variety of disease states such as cancer, cardiovascular complications and inflammatory disorders. Despite increasing scientific and clinical interest in this field, there are still no standardized procedures available for the purification, detection, and characterization of EVs...

In this paper, silver nanoparticles (Ag NPs) are synthesized using Achillea millefolium L. extract as reducing and stabilizing agents and peach kernel shell as an environmentally benign support. FT-IR spectroscopy, UV-Vis spectroscopy, X-ray Diffraction (XRD), Field emission scanning electron microscopy (FESEM), Energy Dispersive X-ray Spectroscopy (EDS), Thermo gravimetric-differential thermal analysis (TG-DTA) and Transmission Electron Microscopy (TEM) were used to characterize peach kernel shell, Ag NPs, and Ag NPs/peach kernel shell...

BACKGROUND AND PURPOSE: Astroglia contributes to the pathophysiology of major depression and the action of antidepressant drugs through modulating synaptic plasticity; therefore, present study investigated whether fast antidepressant action of ketamine is reflected in the rapid alteration of the astrocytes morphology in a genetic animal model of depression. EXPERIMENTAL APPROACH: S-Ketamine (15 mg/kg) or saline was administered as a single injection to Flinders Line (FSL/FRL) rats...

The magnitude of lymphocytosis following exercise is directly related to exercise intensity. Infection with cytomegalovirus (CMV) also augments lymphocytosis after exercise. It is not known if the enhanced T-cell response to exercise due to CMV depends on exercise intensity. Furthermore, exercise-induced changes in T-cell expression of type I and type II cytokines are thought to be intensity dependent, but direct comparisons are lacking. The aim of this experiment was to determine if CMV affects the exercise-induced redistribution of T-cell subsets at varying intensities, and determine the effect of exercise intensity on CD8(+) T-cell cytokine expression...

Most cases of atrial myxoma are sporadic, and the exact etiology is unknown. We examined if herpes simplex virus (HSV)-1 and HSV-2 antigens and/or DNA could be detected in a cohort of Iranian patients with cardiac myxomas. From July 2004 to June 2014, among a total of 36,703 patients undergoing open heart surgeries, consecutive patients with cardiac myxoma who were treated by surgical excision at our center included in this study. Of 73 patients studied, 56% were female with a mean age of 54 years (ranging from 23 to 77 years)...

BACKGROUND/AIM: The purpose of this study was to examine steroid pretreatment in order to decrease postoperative coagulopathy disorders and bleeding. MATERIALS AND METHODS: In this randomized double-blinded study, the efficacy of low versus high doses of methylprednisolone on the coagulation system and postoperative bleeding was compared in patients who were undergoing cardiac surgery with cardiopulmonary bypass (CPB). The platelet response to agonists, D-dimer concentration, tissue plasminogen activator (tPA), plasminogen activator inhibitor (PAI-1) antigens, and platelet receptors CD42b, CD62P, and CD41a were evaluated...

BACKGROUND/AIM: The basolateral amygdala (BLA) modulates memory for emotional events and is involved in both stress and memory. This study investigated different durations of stress and the role of BLA on serum corticosterone level and spatial and cognitive memory. MATERIALS AND METHODS: Different durations of stress (acute, mid, and chronic stress), with and without BLA lesion were induced in rats by 6 h/day restraint stress for 1, 7, and 21 days. Memory functions were evaluated by novel object recognition (NOR) and object location test (OLT)...

Sleep, as one of the most important requirements of our brain, has a mystical nature. Despite long-standing studies, the molecular mechanisms and physiological properties of sleep have not been defined well as the complexity of the mammals' brain make it difficult to investigate the mechanisms and properties of sleep. Although some features of sleep have changed during evolution, its existence in such a simple animal, Caenorhabditis elegans, not only signifies the importance of sleep in even simple animals, but also allows the scientist to assess the core mechanism and biological events in an uncomplicated organism...

Prenatal diagnosis of critical congenital heart disease (CHD) is associated with decreased morbidity. It is also associated with lower birth weights and earlier gestational age at delivery. The University of California Fetal Consortium (UCfC) comprises five tertiary medical centers, and was created to define treatment practices. We utilized this consortium to assess delivery patterns and outcomes in subjects with prenatal and postnatal diagnosis of CHD. A retrospective cohort study was conducted on maternal-neonatal pairs diagnosed with complex CHD prenatally (n = 186) and postnatally (n = 110) from 2011 to 2013...

OBJECTIVE: Biebersteinia (Geraniaceae) has a history of use in traditional medicine in some countries including Iran. In the present study, cytotoxic and apoptogenic properties of hydro-ethanol extract of B. multifidi was investigated on human prostate cancer cell lines (PC3 and DU 145) and human embryonic kidney 293 (HEK293) cells. MATERIALS AND METHODS: Cells were cultured in RPMI-1640 medium supplemented with 10% FBS at 37ºC in a humidified atmosphere of 95% air and 5% CO2...

Saffron is one of the highly exotic spices known for traditional values and antiquity. It is used for home décor besides serving as a colorant flavor and is widely known for medicinal value. Over the last few years, saffron has garnered a lot of interest due to its anti-cancer, anti-mutagenic, anti-oxidant and immunomodulatory properties. Integration of systems biology approaches with wide applications of saffron remains a growing challenge as new techniques and methods advance. Keeping in view of the dearth of a review summarizing the omics and systems biology of saffron, we bring an outline on advancements in integrating omic technologies, the medicinal plant has seen in recent times...

INTRODUCTION: Diabetes, hypertension, and obesity increase risk of chronic kidney disease and associated mortality. Race and SES differences in the effects of these risk factors are, however, still unknown. Current study aimed to investigate whether or not race and SES alter the effects of diabetes, hypertension, and obesity on mortality due to renal diseases. MATERIALS AND METHODS: Data came from the Americans' Changing Lives Study (ACL), 1986 to 2011, a nationally representative prospective cohort of adults with 25 years of follow up...

AIM: Anterior-oblique (AO) proton beams can form an attractive option for prostate patients receiving external beam radiotherapy (EBRT) as they avoid the femoral heads. For a cohort with hydrogel prostate-rectum spacers, we asked whether it was possible to generate AO proton plans robust to end-of-range elevations in linear energy transfer (LET) and modeled relative biological effectiveness (RBE). Additionally we considered how rectal spacers influenced planned dose distributions for AO and standard bilateral (SB) proton beams versus intensity-modulated radiotherapy (IMRT)...

BACKGROUND: Elimination of rosiglitazone in humans is via hepatic metabolism. The existing studies suggest that CYP2C8 is the major enzyme responsible, with a minor contribution from CYP2C9; however, other studies suggest the involvement of additional cytochrome P450 enzymes and metabolic pathways. Thus a full picture of rosiglitazone metabolism is unclear. OBJECTIVE: This study aimed to improve the current understanding of potential drug-drug interactions and implications for therapy by evaluating the kinetics of rosiglitazone metabolism and examining the impact of specific inhibitors on its metabolism using the substrate depletion method...

A new series of quinoline analogues was designed and synthesized as Hsp90 inhibitors. The cytotoxic activity of the synthesized compounds was evaluated against three human cancer cell lines including MCF-7 (human breast cancer cells), DU145 (human prostate cancer cell lines), and A549 (adenocarcinomic human alveolar basal epithelial cells). Some of our compounds (13a-13f) showed significant cytotoxic activity on MCF-7 cells. The most potent anti-proliferative compounds were also tested against Her2, a client protein of Hsp90...
