BACKGROUND: Elevated MYB expression has been documented in adenoid cystic carcinoma (ACC), cylindroma, and spiradenoma, but the specificity of this finding is unknown. CD117 and SOX-10 expression also occurs in some cutaneous adnexal tumors. This study assesses MYB, CD117, and SOX-10 expression in cutaneous adnexal tumors. METHODS: Retrospective analysis of 184 benign adnexal tumors (140 eccrine/apocrine, 40 follicular, and 10 sebaceous), and 30 malignant adnexal tumors was performed with MYB, SOX-10, and CD117 immunostaining...

BACKGROUND: Deep vein thrombosis (DVT) is a common but elusive illness that can result in long-term disability or death. Accurate detection of thrombosis and assessment of its size and distribution are critical for treatment decision-making. In the present study, we sought to develop and evaluate a cardiovascular magnetic resonance (CMR) black-blood thrombus imaging (BTI) technique, based on delay alternating with nutation for tailored excitation black-blood preparation and variable flip angle turbo-spin-echo readout, for the diagnosis of non-acute DVT...

Caregiver maltreatment induces vulnerability to later-life psychopathology. Clinical and preclinical evidence suggest changes in prefrontal and limbic circuitry underlie this susceptibility. We examined this question using a rat model of maternal maltreatment and methods translated from humans, resting-state functional magnetic resonance imaging (R-fMRI). Rat pups were reared by mothers provided with insufficient or abundant bedding for nest building from postnatal (PN) days 8 to 12 and underwent behavioral assessments of affect-related behaviors (forced swim, sucrose preference and social interaction) in adolescence (PN45) and early adulthood (PN60)...

Extract of Salvia miltiorrhiza and Dalbergia Odorifera (SM-DOO) has been traditionally used for the prevention and treatment of cardiovascular diseases. However, information regarding the pharmacodyamic material basis and potential mechanism remain unknown. Male Sprague-Dawley rats were divided into four groups: Sham, Model, Diltiazem and SM-DOO group, n=6. Rats were pretreated with homologous drugs for 7 days, then subjected to 30 min of ischemia followed by 180 min of reperfusion. Cardioprotection effects of SM-DOO on myocardial ischemia/reperfusion (MI/R) injury rats were examined by hemodynamic, infarct area, histopathology, biochemical indicators and western blot analysis...

At present, the mechanisms by which general anesthetics causing loss of consciousness remain unclear. The central medial thalamic nucleus (CMT) is a rarely studied component of the midline thalamic complex, which is deemed to be a part of the nonspecific arousal system. Despite the fact that CMT participates in modulating arousal and receives excitatory noradrenergic projections from locus coeruleus (LC), it remains unknown whether the noradrenergic pathway in the CMT takes part in modulating the arousal system...

REVIEW
Martin Mayer
BACKGROUND: The most recent joint guidelines from the American Heart Association (AHA) and American College of Cardiology (ACC) on the management of non-ST-elevation acute coronary syndromes (NSTE-ACS) are a result of a substantial and considered undertaking, and those involved deserve much recognition for their efforts. However, the handling of anticoagulants seems somewhat inadequate, and this is a highly-relevant matter when managing NSTE-ACS. OBJECTIVE OF THE REVIEW: Among areas of potential uncertainty, emergency medicine professionals might still be left wondering about the particulars of anticoagulant therapy when pursuing ischemia-guided management of NSTE-ACS (that is, managing NSTE-ACS without an intent for early invasive measures, such as coronary angiography and revascularization)...

RTC-1 has recently been identified as a member of a new class of anti-diabetic compounds acting through the inhibition of complex I of the mitochondrial respiratory chain (NADH:ubiquinone oxidoreductase) to improve glucose handling and inhibit weight gain in mice fed a high-fat diet (HFD). The exact mechanism by which the reduced activity of NADH:ubiquinone oxidoreductase, in response to RTC-1, promotes these improved metabolic parameters remains to be established. Through extensive in vitro analysis, new molecular insights into these downstream signalling pathways have been obtained...

Tumor cell proliferation and migration processes are regulated by multiple metabolic pathways including glycolysis and de novo lipogenesis. Since acetyl-CoA carboxylase (ACC) is at the junction of lipids synthesis and oxidative metabolic pathways, we investigated whether use of a dual ACC inhibitor would provide a potential therapy against certain lipogenic cancers. The impact of dual ACC1/ACC2 inhibition was investigated using a dual ACC1/ACC2 inhibitor as well as dual siRNA knock down on the cellular viability and metabolism of two glioblastoma multiform cancer cell lines, U87 and a more aggressive form, U87 EGFRvIII...

Microtubule associated protein tau (tau) deposition is associated with a spectrum of neurodegenerative diseases collectively termed tauopathies. We have previously shown that amyotrophic lateral sclerosis (ALS) with cognitive impairment (ALSci) is associated with tau phosphorylation at Thr(175) and that this leads to activation of GSK3β which then induces phosphorylation at tau Thr(231). This latter step leads to dissociation of tau from microtubules and pathological tau fibril formation. To determine the extent to which this pathway is unique to ALS, we have investigated the expression of pThr(175) tau and pThr(231) tau across a range of frontotemporal degenerations...

Genomic instability is frequently caused by nucleic acid structures termed R-loops that are formed during transcription. Despite their harmful potential, mechanisms that sense, signal, and suppress these structures remain elusive. Here, we report that oscillations in transcription dynamics are a major sensor of R-loops. We show that pausing of RNA polymerase II (RNA Pol II) initiates a signaling cascade whereby the serine/arginine protein kinase 2 (SRPK2) phosphorylates the DDX23 helicase, culminating in the suppression of R-loops...

In human skeletal muscle, PGC-1α is constitutively expressed via the canonical promoter. By contrast, the expression of PGC-1α mRNA via the alternative promoter was found to be highly dependent on the intensity of exercise and to contribute largely to the post-exercise increase of total PGC-1α mRNA. This study investigated the role of AMPK in regulating PGC-1α gene expression via the alternative promoter through a cAMP responsive element-binding protein-1 (CREB1)-dependent mechanism in human skeletal muscle...
