BACKGROUND: Renal ischemia-reperfusion (IR) leads to alterations of tubular epithelial cells, interstitial microvasculopathy and endothelial cell dysfunction in peritubular capillaries. Although dextrans have deteriorative effects on healthy kidney, their favorable effects on post-ischemic microvascular disturbances have been demonstrated. Therefore, we aimed to investigate in vivo effects of systemic Dextran 70 administration in kidney tissue with ischemia-reperfusion injury. METHODS: Twenty-one rats were allocated as sham, IR and IR+ Dextran 70 treatment groups...

REVIEW
Jae Youn Cheong
Cirrhotic patients have bleeding tendencies due to the lack of coagulation factors and thrombocytopenia. However, decreased levels of procoagulants are also accompanied by decreased levels of natural anticoagulants. However, there have been contrasting reports. It has been reported that patients with cirrhosis are at risk for thrombotic complications, including portal vein thrombosis and venous thromboembolism. Physicians consider active anticoagulation for prophylaxis and treatment of portal vein thrombosis and/or venous thromboembolism in cirrhotic patients with high risk of thrombosis...

The cellular and molecular events that take place during brain development play an important role in governing function of the mature brain. Lipid signalling molecules such as prostaglandin E2 (PGE2 ) play an important role in healthy brain development. Abnormalities along the COX/PGE2 signalling pathway due to genetic or environmental causes have been linked to Autism Spectrum Disorders (ASDs). This study aims to evaluate the effect of altered COX/PGE2 signalling on development and function of the prenatal brain using male mice lacking cyclooxygenase-1 and -2 (COX-1(-/-) and COX-2(-/-) ) as potential model systems of ASD...

BACKGROUND AND PURPOSE: Neuronal regeneration from endogenous precursors is an attractive strategy for the treatment of ischemic stroke; however, most stroke-generated new born neurons die over time. Therefore, a drug that is both neuroprotective and pro-neurogenic may be promising. In this study, we assessed the neurogenic and oligodendrogenic effects of tetramethylpyrazine nitrone (TBN), a neuroprotective drug candidate for stroke, in a rat model of ischemic stroke. EXPERIMENTAL APPROACH: Sprague Dawley (SD) rats were subjected to middle cerebral artery occlusion (MCAO)...

BACKGROUND AND PURPOSE: Several anti-angiogenic cancer drugs that inhibit VEGF receptor (VEGFR) signalling for efficacy are associated with a 15-60% incidence of hypertension. Tyrosine kinase inhibitors (TKIs) that have off-target activity at VEGFR-2 may also cause blood pressure elevation as an undesirable side effect. Therefore, the ability to translate VEGFR-2 off-target potency into blood pressure elevation would be useful in development of novel TKIs. EXPERIMENTAL APPROACH: We sought to quantify the relationship between VEGFR-2 inhibition and blood pressure elevation for a range of kinase inhibitors...

An indicator of movement quality and potential injury risk during Functional Movement Screen (FMS) testing is the presence of asymmetry when comparing the left and right sides of the body. The aim of the study was to investigate the reproducibility of the injury risk model proposed in our previous research (Chalmers et al. 2017; derivation study) that showed an increased injury risk for elite junior Australian football players demonstrating ≥2 asymmetrical FMS sub-tests. We used a direct replication design...

The single leg supine bridge (SLB) is a commonly employed strengthening exercise and is used as a clinical test for hamstring function in sports, however, little is known about the patterns of muscle activation in this task. To explore these activation patterns, nine healthy, recreationally active males underwent functional magnetic resonance imaging (fMRI) of their thighs at rest and immediately after 5 sets of 10 repetitions of the SLB exercise. Exercise-induced increases in the transverse (T2) relaxation time of the biceps femoris long and short heads, semitendinosus and semimembranosus, were determined via signal intensity changes in pre- and post-exercise images and used as an index of muscle activation...

Autonomic dysfunction appears to be prevalent in people living with HIV/AIDS (PLWHA). However, there are limited data on the resting autonomic responses to exercise in active and insufficiently active PLWHA. We aimed to determine whether active PLWHA have better autonomic responses compared with insufficiently active PLWHA. Active PLWHA receiving anti-retroviral therapy (n=13) and insufficiently active PLWHA (n=10) were recruited. A 10-min recording of the supine electrocardiogram was taken. Resting heart rate variability was analyzed from this electrocardiogram...

BACKGROUND/AIMS: The generation of reactive oxygen species (ROS) caused by amyloid-β (Aβ) is considered to be one of mechanisms underlying the development of Alzheimer's disease. Curcumin can attenuate Aβ-induced neurotoxicity through ROS scavenging, but the protective effect of intracellular curcumin on neurocyte membranes against extracellular Aβ may be compromised. To address this issue, we synthesized a palmitic acid curcumin ester (P-curcumin) which can be cultivated on the cell membrane and investigated the neuroprotective effect of P-curcumin and its interaction with Aβ...

Stable and sustainable spermatogenesis is supported by the strict regulation of self-renewal and differentiation of spermatogonial stem cells (SSC), which are a rare population of undifferentiated spermatogonia. It has been revealed that some signaling factors regulate the self-renewal of SSC; however, the molecular mechanism of SSC maintenance is still not completely understood. Notch signaling is an evolutionarily conserved juxtacrine signaling that plays important roles in the cell fate determination of various tissue stem cells...

BACKGROUND: Excessive daytime sleepiness (EDS) is a common and significant problem encountered in affective illness, however, the biological underpinnings of EDS in persons with psychiatric disorders are not clear. This study evaluated the associations between thalamic connectivity with cortical and subcortical brain regions with EDS in persons with and without depressive disorders (DD). METHODS: Resting-state functional connectivity magnetic resonance imaging scans from 67 unmedicated young to middle-aged women with current DD (n = 30), remitted DD (n = 13), and healthy controls (n = 24) were utilized to examine the associations between thalamic connectivity with cortical/subcortical structures and EDS...
