Fatal Outcome of Multiple Clinical Presentations of Human Herpesvirus 8-related Disease After Solid Organ Transplantation.

Kaposi sarcoma is the most common human herpesvirus 8 (HHV-8)-related disease described after solid organ transplantation. Multicentric Castleman disease and hemophagocytic syndrome are other potential HHV-8-induced entities but are less frequently reported. We describe the case of a liver transplant recipient who presented with an acute febrile illness 1 year after transplantation with a rapidly fatal outcome. Autopsy revealed 3 distinct HHV-8-related entities: Kaposi sarcoma, HHV-8-associated multicentric...


Disturbed Flow Induces Autophagy, but Impairs Autophagic Flux to Perturb Mitochondrial Homeostasis.

Temporal and spatial variations in shear stress are intimately linked with vascular metabolic effects. Autophagy is tightly regulated in intracellular bulk degradation/recycling system for maintaining cellular homeostasis. We postulated that disturbed flow modulates autophagy with an implication in mitochondrial superoxide (mtO2(•-)) production.


Photoredox-Catalyzed Intramolecular Aminodifluoromethylation of Unactivated Alkenes.

A photoredox catalyzed aminodifluoromethylation of unactivated alkenes has been developed in which HCF2SO2Cl is used as the HCF2 radical source. Sulfonamides were active nucleophiles in the final step of a tandem addition/oxidation/cyclization process to form pyrrolidines, and esters were found to cyclize to form lactones. Thus, a variety of pyrrolidines and lactones were obtained in moderate to excellent yield. In order for the cyclization reactions to be efficient, a combination of a copper catalyst (Cu(d...


Blood Conservation Techniques and Platelet Function in Cardiac Surgery: Retraction.


Intraoperative Protective Mechanical Ventilation for Prevention of Postoperative Pulmonary Complications: A Comprehensive Review of the Role of Tidal Volume, Positive End-expiratory Pressure, and Lung Recruitment Maneuvers.

Postoperative pulmonary complications are associated with increased morbidity, length of hospital stay, and mortality after major surgery. Intraoperative lung-protective mechanical ventilation has the potential to reduce the incidence of postoperative pulmonary complications. This review discusses the relevant literature on definition and methods to predict the occurrence of postoperative pulmonary complication, the pathophysiology of ventilator-induced lung injury with emphasis on the noninjured lung, and ...


Halothane Modulates the Type I Interferon Response to Influenza and Minimizes the Risk of Secondary Bacterial Pneumonia through Maintenance of Neutrophil Recruitment in an Animal Model.

To minimize the risk of pneumonia, many anesthesiologists delay anesthesia-requiring procedures when patients exhibit signs of viral upper respiratory tract infection. Postinfluenza secondary bacterial pneumonias (SBPs) are a major cause of morbidity and mortality. An increased host susceptibility to SBP postinfluenza has been attributed to physical damage to the pulmonary epithelium, but flu-induced effects on the immune system are being shown to also play an important role. The authors demonstrate that ha...


Use of the Modified Emotional Stroop Task to Detect Suicidality in College Population.

This cross-sectional study investigated the usefulness of the emotional Stroop task (EST) as a behavioral marker for suicidal behaviors in a college population. Eight hundred twenty college students were asked to perform on the EST and to respond to suicide-related self-report measures. The results indicated that past suicide attempters were slower in responding to the word "suicide" as compared to nonattempters, and female past attempters showed more delayed response when their most recent attempt was made...


When Higher Working Memory Capacity Hinders Insight.

Higher working memory capacity (WMC) improves performance on a range of cognitive and academic tasks. However, a greater ability to control attention sometimes leads individuals with higher WMC to persist in using complex, attention-demanding approaches that are suboptimal for a given task. We examined whether higher WMC would hinder insight problem solving, which is thought to rely on associative processes that operate largely outside of close attentional control. In addition, we examined whether character...


Bridging Gaps in Common Ground: Speakers Design Their Gestures for Their Listeners.

Communication is shaped both by what we are trying to say and by whom we are saying it to. We examined whether and how shared information influences the gestures speakers produce along with their speech. Unlike prior work examining effects of common ground on speech and gesture, we examined a situation in which some speakers have the same amount of mutually shared experience with their listener but the relevance of the information from shared experience is different for listeners in different conditions. Ad...


Carving Executive Control at Its Joints: Working Memory Capacity Predicts Stimulus-Stimulus, But Not Stimulus-Response, Conflict.

Three experiments examined the relation between working memory capacity (WMC) and 2 different forms of cognitive conflict: stimulus-stimulus (S-S) and stimulus-response (S-R) interference. Our goal was to test whether WMC's relation to conflict-task performance is mediated by stimulus-identification processes (captured by S-S conflict), response-selection processes (captured by S-R conflict), or both. In Experiment 1, subjects completed a single task presenting both S-S and S-R conflict trials, plus trials ...


β-Guanidinopropionic acid extends the lifespan of Drosophila melanogaster via an AMP-activated protein kinase-dependent increase in autophagy.

Previous studies have demonstrated that AMP-activated protein kinase (AMPK) controls autophagy through the mammalian target of rapamycin (mTOR) and Unc-51 like kinase 1 (ULK1/Atg1) signaling, which augments the quality of cellular housekeeping, and that β-guanidinopropionic acid (β-GPA), a creatine analog, leads to a chronic activation of AMPK. However, the relationship between β-GPA and aging remains elusive. In this study, we hypothesized that feeding β-GPA to adult Drosophila produces the lifespan ex...


Flavin-protein Complexes: Aromatic Stacking assisted by a Single Hydrogen Bond.

Enzyme catalyzed reactions often rely on a noncovalently bound cofactor whose reactivity is tuned by its immediate environment. Flavin cofactors, the most versatile catalyst encountered in biology, are often maintained within the protein throughout numbers of complex ionic and aromatic interactions. Here, we have investigated the role of pi-pi stacking and hydrogen bond interactions between a tyrosine and the isoalloxazine moiety of the flavin adenine dinucleotide (FAD) in an FAD-dependent RNA methyltransfe...




Are alcohol outlet densities strongly associated with alcohol-related outcomes? A critical review of recent evidence.

There have been reviews on the association between density of alcohol outlets and harm including studies published up to December 2008. Since then the number of publications has increased dramatically. The study reviews the more recent studies with regard to their utility to inform policy.


Long-term outcome of infliximab in severe chronic and refractory systemic sarcoidosis: report of 16 cases.

Infliximab (IFX) appears to be effective in refractory sarcoidosis. However, data are lacking regarding its efficacy in severe sarcoidosis (i.e. with cardiac and/or neurological involvement).


Chemiresistive Sensing Behavior of SnO2 (n)-Cu2O (p) Core-Shell Nanowires.

We report the synthesis of SnO2?Cu2O n?p core?shell nanowires (C?S NWs) and their use as chemiresistive sensors for detecting trace amounts of gas. The n?p C?S NWs were synthesized by a two-step process, in which the core SnO2 nanowires were prepared by the vapor growth technique and subsequently the Cu2O shell layers were deposited by atomic layer deposition. A systematic investigation of the sensing capabilities of the n?p C?S NWs, particularly as a function of shell thickness, revealed the underlying sen...


Comment on "Improved Calibration of Voltammetric Sensors for Studying Pharmacological Effects on Dopamine Transporter Kinetics in Vivo".


A comparison of location of acute symptomatic vs. 'silent' small vessel lesions.

Acute lacunar ischaemic stroke, white matter hyperintensities, and lacunes are all features of cerebral small vessel disease. It is unclear why some small vessel disease lesions present with acute stroke symptoms, whereas others typically do not.


Approaching the limit of Cu(II)/Cu(I) mixed valency in a Cu(I)Br2-N-methylquinoxalinium hybrid compound.

A novel 1D hybrid salt (MQ)[CuBr2]∞ (MQ = N-methylquinoxalinium) is reported. Structural, spectroscopic and magnetic investigations reveal a minimal Cu(II) doping of less than 0.1%. However it is not possible to distinguish Cu(I) and Cu(II). The unusually close packing of the organic moieties and the dark brown colour of the crystals suggest a defect electronic structure.


An ionic liquid facilitates the conjugative transfer of antibiotic resistance genes mediated by plasmid RP4.

The dissemination and propagation of antibiotic resistance genes (ARGs) is an emerging global health concern. In our previous study, an ionic liquid (IL) 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIm][PF6]) had been proven to facilitate the dissemination of ARGs via horizontal gene transfer. In this study, we further confirm that this compound facilitates the horizontal transfer of plasmid RP4 through a conjugation mechanism and not by natural transformation. The mechanisms of [BMIm][PF6] promoting...


Immunization of Mice with Anthrax Protective Antigen Limits Cardiotoxicity but Not Hepatotoxicity Following Lethal Toxin Challenge.

Protective immunity against anthrax is inferred from measurement of vaccine antigen-specific neutralizing antibody titers in serum samples. In animal models, in vivo challenges with toxin and/or spores can also be performed. However, neither of these approaches considers toxin-induced damage to specific organ systems. It is therefore important to determine to what extent anthrax vaccines and existing or candidate adjuvants can provide organ-specific protection against intoxication. We therefore compared the...


Polymer@MOF@MOF: "grafting from" atom transfer radical polymerization for the synthesis of hybrid porous solids.

The application of a core-shell architecture allows the formation of a polymer-coated metal-organic framework (MOF) maintaining high surface area (2289-2857 m(2) g(-1)). The growth of a MOF shell from a MOF core was used to spatially localize initiators by post-synthetic modification. The confinement of initiators ensures that polymerization is restricted to the outer shell of the MOF.


Abdominal fat distribution and cardiovascular risk in men and women with different levels of glucose tolerance.

Regional fat distribution rather than overall obesity has been recognised as important to understand the link between obesity and cardiovascular disease.


ApoE4 determines the reduction in LDL-C after GH replacement therapy in children with an idiopathic GH deficiency.

Growth hormone (GH) activates the expression of low-density lipoprotein (LDL) receptors, leading to decreased LDL-cholesterol (LDL-C). Apolipoprotein E4 (apoE4) carriers suppress LDL-receptor expression, rendering high LDL-C concentrations.


Mean platelet volume is closely associated with serum glucose level, but not with arterial stiffness and carotid atherosclerosis in patients with type 2 diabetes.

Mean platelet volume (MPV) has been suggested as a predictive biomarker for cardiovascular disease.
