Magnetic resonance spectroscopy (MRS) is the only biomedical imaging method that can noninvasively detect endogenous signals from the neurotransmitter γ-aminobutyric acid (GABA) in the human brain. Its increasing popularity has been aided by improvements in scanner hardware and acquisition methodology, as well as by broader access to pulse sequences that can selectively detect GABA, in particular J-difference spectral editing sequences. Nevertheless, implementations of GABA-edited MRS remain diverse across research sites, making comparisons between studies challenging...

Mulberry anthocyanins possess many pharmacological effects including liver protection, anti-inflammation, and anticancer. The aim of this study was to evaluate whether mulberry anthocyanin extract (MAE) exerts beneficial effects against oxidative stress damage in HepG2 cells and Caenorhabditis elegans. In vitro, MAE prevented cytotoxicity, increased glucose consumption and uptake, and eliminated excessive intracellular free radicals in H2O2-induced cells. Moreover, MAE pretreatment maintained Nrf2, HO-1, and p38 MAPK stimulation and abolished upregulation of p-JNK, FOXO1, and PGC-1α that were involved in oxidative stress and insulin signalling modulation...

OBJECTIVE: Prior studies have suggested a relationship between operative (Op) time and outcome after major vascular procedures. This study analyzed factors associated with Op time and outcome after carotid endarterectomy (CEA) in the Vascular Quality Initiative (VQI) registry. METHODS: Elective, primary CEAs without high anatomic risk or concomitant procedures from 2012 to 2015 in the VQI were analyzed (N = 26,327, performed by 1188 surgeons from 249 centers). Multivariable analysis was used to identify patient, procedure, and surgeon factors associated with Op time and major adverse events (MAEs), categorized as either technical (ipsilateral stroke, cranial nerve injury, reoperation) or cardiac (myocardial infarction, congestive heart failure, dysrhythmia requiring treatment, surgical site infection, and death)...

Oil pollution in the marine environment is an unavoidable problem due to chronic input from local sources, particularly in urban areas and oil spills. Oil pollution not only causes immediate physical damages to surrounding wildlife but also some components, including higher molecular weight PAHs, can persist in the environment for many years and pose insidious threats to the ecosystem. Long-term and nontargeted monitoring of oil pollution is important. This paper examines the ability of International Pellet Watch (IPW) for initial identification and monitoring of oil pollution by analysing PAHs and hopanes in plastic pellet samples collected globally by volunteers...

Single-walled carbon nanotubes (SWCNTs) are reported to spontaneously align in a rotational pattern by drying a liquid droplet of toluene containing polyfluorene as a dispersant. By situating a droplet of an SWCNT solution around a glass bead, spiral patterns are generated. The parallel alignment of SWCNTs along one stripe of such a pattern is confirmed using scanning electron microscopy and polarized optical microscopy. The orientation order increases toward the outer edge of a stripe. The stripe width in the pattern is proportional to the solute concentration, and the width and position of the stripes follow geometric sequences...

We report our fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography ((18)FFDG PET/CT) findings in a 51 years old female presenting with B symptoms, respectively fever, night sweats and malaise, that underwent an (18)F-FDG PET/CT examination to exclude underlying lymphomatous disease. Whereas (18)F-FDG PET scan findings were negative, CT put to evidence the presence of multiple small lesions suggestive for multifocal hamartoma. On a subsequently performed magnetic resonance imaging (MRI) of the spleen, multiple infracentimetric foci were visualized displaying characteristic findings for hamartoma...

Twin studies show the established relation between bulimic symptoms and problematic alcohol involvement in adult females is partly due to shared familial factors, specifically shared genetic effects. However, it is unclear if similar shared etiological factors exist during adolescence or in males. We examined the familial overlap (i.e., genetic and common environmental correlations) between bulimic symptoms and various levels of alcohol involvement in 16- to 17-year-old female and male same-sex twin pairs using sex-specific biometrical twin modeling...

The etiology of purpura in Sjögren syndrome (SS) includes cryoglobulinemia, hypergammaglobulinemia, and leukocytoclastic vasculitis (LCV). The clinical symptoms of LCV associated with SS comprise palpable or nonpalpable purpura and urticarial vasculitis. Here, we report a case of LCV presenting as erythema gyratum repens (EGR)-like purpura in a 62-year-old woman with rheumatoid arthritis and SS. EGR-like skin lesions, characterized by annular lesions with expanding concentric pattern and coalescing to form a zebra-like pattern or grain of wood pattern, can appear in various autoimmune conditions; however, EGR-like eruption in SS is extremely rare...

With increasing the application of decision support systems in various fields, using such systems in different aspects of medical science has been growing. Drug's dose prediction is one of the most important issues which can be improved using decision support systems. In this paper, a new multi-objective feature approach has been proposed to support warfarin dose prediction decision. Warfarin is an anticoagulant normally used in the prevention of the formation of clots. This research was conducted on 553 patients during 2013-2015 who were candidates for using warfarin and their INR was in the target range...
