HIV infection affects 37 million people and about 1.7 million are infected annually. Among the phase III clinical trials only the RV144 vaccine trial elicited significant protection against HIV-1 acquisition, but the efficacy and immune memory were inadequate. To boost these vaccine functions we studied T stem cell memory (TSCM) and innate immunity. TSCM cells were identified by phenotypic markers of CD4(+) T cells and they were further characterised into 4 subsets. These expressed the common IL-2/IL-15 receptors and another subset of APOBEC3G anti-viral restriction factors, both of which were upregulated...

BACKGROUND: Pregnant women may have an increased risk of stroke compared with nonpregnant women of similar age, but the magnitude and the timing of such risk are unclear. We examined the risk of a first stroke event in women of childbearing age and compared the risk during pregnancy and in the early postpartum period with the background risk outside these periods. METHODS AND RESULTS: We conducted an open cohort study of 2 046 048 women aged 15 to 49 years between April 1, 1997, and March 31, 2014, using linked primary (Clinical Practice Research Datalink) and secondary (Hospital Episode Statistics) care records in England...

BACKGROUND: In the last decade, Makerere University College of Health Sciences (MakCHS) has taken strides in research and training to improve healthcare through collaborative training and research programs. However, there is limited data on the trends of MakCHS faculty contributions to research and on faculty growth to take leading roles in health research. This paper reviews MakCHS faculty research publications over 15.5 years and outlines possible strategies to enhance faculty research outputs...

OBJECTIVES: Pazopanib received US Food and Drug Administration approval in 2009 for advanced renal cell carcinoma. During clinical development, liver chemistry abnormalities and adverse hepatic events were observed, leading to a boxed warning for hepatotoxicity and detailed label prescriber guidelines for liver monitoring. As part of postapproval regulatory commitments, a cohort study was conducted to assess prescriber compliance with liver monitoring guidelines. METHODS: Over a 4-year period, a distributed network approach was used across 3 databases: US Veterans Affairs Healthcare System, a US outpatient oncology community practice database, and the Dutch PHARMO Database Network...

Orthogonal attachment of polar and nonpolar side-chains to a zinc porphyrin-perylenediimide dyad (ZnP-PDI, 1a) is shown to result in self-assembly of ordered supramolecular ribbons in which the ZnP and PDI molecules form segregated π-stacked columns. Following photoexcitation of the ordered ribbons, ZnP(+•)-PDI(-•) radical ion pairs form in <200 fs and subsequently produce a 30 ± 3% yield of free charge carriers that live for about 100 μs. Elongating the side chains on ZnP and PDI in 1b enhances the order of the films, but does not result in an increase in free charge carrier yield...

Semiconductor compounds are widely used for photocatalytic hydrogen production applications, where photogenerated electron-hole pairs are exploited to induce catalysis. Recently, powders of a metallic oxide (Sr1-xNbO3, 0.03<x<0.20) were reported to show competitive photocatalytic efficiencies under visible light, which was attributed to interband absorption. This discovery expanded the range of materials available for optimized performance as photocatalysts. Here we study epitaxial thin films of SrNbO3+δ and find that their bandgaps are ∼4...

General practitioners (GPs) are increasingly managing patients with class 2 and 3 obesity (body mass index [BMI] > 35 and 40 kg/m(2) , respectively). Bariatric surgery is considered for patients with class 2 obesity and comorbidities or class 3 obesity where sustained weight loss using non-surgical interventions has not been achieved. In Australia, GPs facilitate access to surgery through referral processes, but the nature of GP involvement in bariatric pre- and post-surgery care is currently unclear...

Fontan patients managed with warfarin are at risk not only for thrombotic events, but also for bleeding episodes as a consequence of anticoagulation treatment. The aim of this study was to determine whether time spent in patient specified therapeutic range (TTR), when managed in a cardiology-based pharmacist managed anticoagulation clinic (PMAC), is a useful target metric for monitoring, as well as improving outcomes. A single center retrospective review was conducted evaluating TTR of all Fontan patients (n = 45) on warfarin managed in our outpatient cardiology pharmacist managed anticoagulation clinic (PMAC) during a 19 month time frame...

Purpose This study aims to compare outcomes after pyrolytic carbon implant hemiarthroplasty (PH) versus Thompson suspensionplasty (TS) for trapezial-metacarpal (TM) arthritis. Patients and Methods There were 87 arthritic TM joints in 71 patients treated with PH (n = 47 joints, 37 patients) or TS (n = 40 joints, 34 patients). Patients had significantly longer follow-up in the TS group (86.9 months, 25th-75th percentile = 55.6-103.8) versus the PH group (38.4 months, 25th-75th percentile = 23...

The strict species specificity of Human Cytomegalovirus (HCMV) has impeded our understanding of antiviral adaptive immune responses in the context of a human immune system. We have previously shown that HCMV infection of human hematopoietic progenitor cells engrafted in immune deficient mice (huNSG) results in viral latency that can be reactivated following G-CSF treatment. In this study, we characterized the functional human adaptive immune responses in HCMV latently-infected huBLT (humanized Bone marrow-Liver-Thymus) mice...

BACKGROUND: α-Pyrrolidinopentiophenone (α-PVP) has been reported to be rewarding in a variety of pre-clinical models. Given that a number of drugs of abuse have both rewarding and aversive effects, the balance of which influences addiction potential, the present study examined the aversive properties of α-PVP by assessing its ability to induce taste avoidance. This assessment was made in a combined taste avoidance/place conditioning design that also allowed an evaluation of the relationship between α-PVP's aversive and rewarding effects...

OBJECTIVES: To examine trends in and correlates of fighting and violence among youths from the 3 largest racial/ethnic groups in the United States. METHODS: We derived race/ethnicity-specific prevalence estimates for fighting, group fighting, and attacks with intent to harm from the National Survey on Drug Use and Health, a population-based study of youths aged 12 to 17 years. RESULTS: The prevalence of youth fighting and violence decreased significantly in all racial/ethnic groups over the study period (2002-2014), dropping from a high of 33...

Gastric leiomyosarcoma is a recalcitrant cancer and chemotherapy strategy is controversial. The present study used a patient-derived orthotopic xenograft (PDOX) nude mouse model of gastric leiomyosarcoma to identify an effective therapeutic regimen in order to develop individualized precision medicine for this disease. A gastric leiomyosarcoma obtained from a patient was first grown in transgenic nude mice ubiquitously expressing red fluorescent protein (RFP) in order to stably label the tumor stroma. The RFP-expressing tumor was then passaged orthotopically in the gastric wall of non-transgenic nude mice to establish an imageable PDOX (iPDOX) model...

Maintenance of long-term cultures of yeast cells is central to a broad range of investigations, from metabolic studies to laboratory evolution assays. However, repeated dilutions of batch cultures lead to variations in medium composition, with implications for cell physiology. In S. cerevisiae, powerful miniaturized chemostat setups, or ministat arrays, have been shown to allow for constant dilution of multiple independent cultures. Here we set out to adapt these arrays for continuous culture of a morphologically and physiologically distinct yeast, the fission yeast Schizosaccharomyces pombe, with the goal of maintaining constant population density over time...

p-curves provide a useful window for peeking into the file drawer in a way that might reveal p-hacking (Simonsohn, Nelson, & Simmons, 2014a). The properties of p-curves are commonly investigated by computer simulations. On the basis of these simulations, it has been proposed that the skewness of this curve can be used as a diagnostic tool to decide whether the significant p values within a certain domain of research suggest the presence of p-hacking or actually demonstrate that there is a true effect. Here we introduce a rigorous mathematical approach that allows the properties of p-curves to be examined without simulations...
