BACKGROUND/AIM: Diabetes mellitus inhibits wound-induced angiogenesis, impairs the wound healing process, and leads to the development of chronic wounds. Ankaferd BloodStopper (ABS) is a new and promising local haemostatic agent. Although the mechanism of ABS-mediated haemostasis is well established, little is known about the associated histological and biochemical tissue reactions. The aim of this study was to evaluate the effects of this new-generation local haemostatic agent on short-term soft-tissue healing in streptozotocin (STZ)-treated rats...

Our goal was to evaluate the role of ultrasound (US) imaging in an experimental 2-hit steatofibrosis rat model. Nineteen female Sprague-Dawley rats were divided into 2 groups: control group (n = 6) and high-fat diet carbontetrachloride (HFD-CCl4) group (n = 13) that was fed with HFD for 14 weeks. Ultrasound was performed to evaluate liver steatosis. The HFD-CCl4 group rats were divided further into 2 subgroups: HFD rats with liver steatosis [US (+) group; n = 6] and without steatosis [US (-) group; n = 7]. All rats in the subgroups were administered with CCl4...

Occurrence of stroke cases displays a time-of-day variation in human. However, the mechanism linking circadian rhythm to the internal response mechanisms against pathophysiological events after ischemic stroke remained largely unknown. To this end, temporal changes in the susceptibility to ischemia/reperfusion (I/R) injury were investigated in mice in which the ischemic stroke induced at four different Zeitgeber time points with 6-h intervals (ZT0, ZT6, ZT12, and ZT18). Besides infarct volume and brain swelling, neuronal survival, apoptosis, ischemia, and circadian rhythm related proteins were examined using immunohistochemistry, Western blot, planar surface immune assay, and liquid chromatography-mass spectrometry tools...

Sepsis is a complex condition characterized by the simultaneous activation of inflammation and coagulation in response to microbial insult. These events manifest as systemic inflammatory response syndrome or sepsis symptoms through the release of proinflammatory cytokines, procoagulants, and adhesion molecules from immune cells and/or damaged endothelium. Today, sepsis is a severe multisystem disease with difficult treatments for its manifestations and high mortality rates. In the last two decades in particular, many studies have been conducted on sepsis that cause shock, multiorgan dysfunction, and organ failure by especially leading to hemodynamic changes...

MFN2 encodes mitofusin 2, a membrane-bound mediator of mitochondrial membrane fusion and inter-organelle communication. MFN2 mutations cause axonal neuropathy, with associated lipodystrophy only occasionally noted, however homozygosity for the p.Arg707Trp mutation was recently associated with upper body adipose overgrowth. We describe similar massive adipose overgrowth with suppressed leptin expression in four further patients with biallelic MFN2 mutations and at least one p.Arg707Trp allele. Overgrown tissue was composed of normal-sized, UCP1-negative unilocular adipocytes, with mitochondrial network fragmentation, disorganised cristae, and increased autophagosomes...

The gasotransmitter nitric oxide (NO) has an important role in vascular function and a decrease in its bioavailability is accepted as a main pathological mechanism for cardiovascular diseases. However, other gasotransmitters such as hydrogen sulfide (H2S) are also generated by the endothelium and can also affect vascular tone and a crosstalk may exist between H2S and NO. We therefore investigated the consequences of deficiency, replacement or overexpression of endothelial nitric oxide synthase (eNOS) on H2S-induced vascular responses in murine carotid arteries...

Influenza A (H1N1) caused its first pandemic in 2009 in USA and Mexico. Since then, clinicians have exercised great care in order to make an early diagnosis of viral pneumonias. This is due in part to pandemic influenza A infection having greater impact on populations <65 years old than other viral strains, including seasonal influenza. Chest radiographies of those affected displayed a rapid progression of patchy infiltrates, and a large proportion of individuals required admission to intensive care units (ICU)...

PURPOSE: A correlation between breast cancer and thyroid disorders has been described in previous studies. Degraded thyroid hormones are referred to as trace amines. These endogenous amines have the ability to bind to the G-protein-coupled receptor TAAR1 (trace amine-associated receptor) and thereby activate it. TAAR1 is able to modulate the serotonergic and dopaminergic system in the brain and has so far been studied in the neurological field. The following study represents the first investigation of the regulation of TAAR1 in primary breast cancer (no metastases, M0)...
