Classic concepts about the role of epicardial adipose tissue (EpAT) in heart physiology include its role in cardiac metabolism, mechanical protection of coronaries, innervation and possibly cryoprotection of the heart too. Nevertheless, recent evidence has revealed that epicardial adipose tissue regulates multiple aspects of cardiac biology including myocardial redox state, intracellular Ca(2+) cycling, the electrophysiological and contractile properties of cardiomyocytes, cardiac fibrosis as well as coronary atherosclerosis progression...

In this study we characterize a novel positive and single stranded RNA (ssRNA) mycovirus isolated from the rice field isolate of Magnaporthe oryzae Guy11. The ssRNA contains a single open reading frame (ORF) of 2,373 nucleotides in length and encodes an RNA-dependent RNA polymerase (RdRp) closely related to ourmiaviruses (plant viruses) and ourmia-like mycoviruses. Accordingly, we name this virus Magnaporthe oryzae ourmia-like virus 1 (MOLV1). Although phylogenetic analysis suggests that MOLV1 is closely related to ourmia and ourmia-like viruses, it has some features never reported before within the Ourmiavirus genus...

mRNA regulation by poly(A) tail length variations plays an important role in many developmental processes. Recent advances have shown that, in particular, deadenylation (the shortening of mRNA poly(A) tails) is essential for germ-line stem cell biology in the Drosophila ovary. Therefore, a rapid and accurate method to analyze poly(A) tail lengths of specific mRNAs in this tissue is valuable. Several methods of poly(A) test (PAT) assays have been reported to measure mRNA poly(A) tail lengths in vivo. Here, we describe two of these methods (PAT and ePAT) that we have adapted for Drosophila ovarian germ cells and germ-line stem cells...

The patient was a 31-year-old female with no previous health problems; however, during a health checkup in 2013, a nodule (2.5 cm in diameter) was identified in the S10 area of the left lung. No clinical symptoms were apparent. Positron emission tomography/computed tomography revealed an accumulation in the same region. The patient was suspected of having lung cancer, and video-assisted thoracoscopic surgery was performed. A histopathological examination of the resected specimen revealed epithelioid granulomas accompanied by caseous necrosis in the lesion...

Hepatitis C virus (HCV) is a highly diverse pathogen that is classified into seven distinct genotypes. Simultaneous or sequential reinfection with multiple HCV genotypes is recognized in high-risk populations, such as injecting drug users (IDUs). Multiple infection is of clinical concern as different genotypes have various sensitivities to current antiviral therapies. Therefore, a better understanding of the frequency of multiple infection and of the genotypes currently being transmitted is clinically relevant...

RATIONALE: Adiponectin has anti-inflammatory effects in experimental models, but its role in the regulation of myocardial redox state in humans is unknown. Although adiponectin is released from epicardial adipose tissue (EpAT), it is unclear whether it exerts any paracrine effects on the human myocardium. OBJECTIVE: To explore the cross talk between EpAT-derived adiponectin and myocardial redox state in the human heart. METHODS AND RESULTS: EpAT and atrial myocardium were obtained from 306 patients undergoing coronary artery bypass grafting...

BACKGROUND: β-Adrenergic receptor blockers (BBs) administered after trauma blunt the cascade of immune and inflammatory changes associated with injury. BBs are associated with improved outcomes after traumatic brain injury (TBI). Propranolol may be an ideal BB because of its nonselective inhibition and ability to cross the blood-brain barrier. We determined if early administration of propranolol after TBI is associated with lower mortality. METHODS: All adults (age ≥ 18 years) with moderate-to-severe TBI (head Abbreviated Injury Scale [AIS] score, 3-5) requiring intensive care unit (ICU) admission at a Level I trauma center from January 1, 2013, to May 31, 2015, were prospectively entered into a database...

BACKGROUND: Although beta-adrenergic receptor blockade may improve outcomes after traumatic brain injury (TBI), its early use is not routine. We hypothesize that judicious early low-dose propranolol after TBI (EPAT) will improve outcomes without altering bradycardia or hypotensive events. METHODS: We conducted a prospective, observational study on all patients who presented with moderate-to-severe TBI from March 2010-August 2013. Ten initial patients did not receive propranolol (control)...

An imaging algorithm is implemented for tomographically reconstructing contrast maps of the space variant speed of diffuse photon density wavefronts (DPDWFs) propagating in biological tissue-like diffusing media. This speed serves as a novel contrast not previously exploited in the literature. The algorithm employs early photon arrival times (EPATs) extracted from a set of time domain measurements. A relationship between EPATs and the speed of DPDWFs is exploited as the forward model. The forward model and its use in an inverse problem are supported by experimental results...

PURPOSE: The evaluation of carotid-cavernous fistulas (CCFs) and the intracranial vasculature has been predominantly carried out using conventional digital subtraction angiography (DSA). Recent developments in time-resolved magnetic resonance angiography (MRA) provide the opportunity to assess both multiple arterial and venous phases with high temporal and spatial resolution. Here, we investigated the feasibility of this technique to functionally assess CCF prior to intervention. METHODS: Six consecutive patients with clinical symptoms of a CCF were scheduled for clinically indicated MRA and underwent a protocol that comprised conventional imaging sequences and high resolution time-resolved MRA with interleaved stochastic trajectories (TWIST)...

Poly(A) tail length is a readout of an mRNA's translatability and stability, especially in developmental systems. PolyAdenylation Test (PAT) assays attempt to quickly measure the average poly(A) tail length of RNAs of experimental interest. Here we present sPAT, splint-mediated PAT, a procedure that uses a DNA splint to aid in the ligation of an RNA-tag to the poly(A) tail of an mRNA. In comparison to other PAT methodologies, including ePAT, sPAT is highly sensitive to low-abundance mRNAs, gives a more accurate profile of the poly(A) tail distribution, and requires little starting material...

OBJECTIVES: To determine factors associated with early pancreatic allograft thrombosis (EPAT). Thrombosis is the leading non-immunological cause of early pancreatic allograft failure. Multiple risk factors have been postulated. We hypothesized that recipient perioperative hypotension was a major risk factor and evaluated the correlation of this and other parameters with EPAT. METHODS: We retrospectively reviewed the records of the 118 patients who received a pancreatic allograft at our center between October 1992 and January 2010...
