Review of the family Bochicidae : with new species and records (Arachnida: Pseudoscorpionida)

A history of the family is presented. All of the genera and species previously assigned to the family are reviewed, and 4 new species are described: Leucohya par va from Venezuela and Guyana, Mexobisium venii from Belize and Guatemala, M. dominicanum from the Dominican Republic, and Paravachonium sprousei from Mexico. Two subfamilies are established: Bochicinae (including the genera Antillobisium, Bochica, Troglobochica, Troglohya, and Vachonium) and Leucohyinae (including Apohya, Leucohya, Mexobisium, and Paravachonium)

New Terrestrial Isopods of the Genus Miktoniscus from Eastern United States (Crustacea: Isopoda: Oniscoidea)

Author Institution: Department of Biology, University of Rochester, Rochester, New Yor

The genus Tyrannochthonius in the eastern United States (Pseudoscorpionida: Chthoniidae). Part I. The historical taxa

All available material pertaining to Tyrannochthonius Chamberlin from the United States east of the Mississippi River has been examined. The range of the single species already described from this area, T. floridensis Malcolm and Muchmore, is extended. Ten new species are described here; all are troglobites from caves in Alabama

The genus Tyrannochthonius in the eastern United States (Pseudoscorpionida: Chthoniidae). Part II. More recently discovered species

Twenty-five new species of Tyrannochthonius, mostly cavernicolous, are described from Alabama, Florida, Kentucky, and Tennessee. Their relations are discussed, and a key is given for all species of the genus known from the United States east of the Mississippi River

Detection of Water Vapor in the Photosphere of Arcturus

We report detections of pure rotation lines of OH and H2O in the K1.5 III red-giant star Arcturus (alpha Bootis) using high-resolution, infrared spectra covering the regions 806-822 cm-1 (12.2-12.4 um) and 884-923 cm-1 (10.8-11.3 um). Arcturus is the hottest star yet to show water-vapor features in its disk-averaged spectrum. We argue that the water vapor lines originate from the photosphere, albeit in the outer layers. We are able to predict the observed strengths of OH and H2O lines satisfactorily after lowering the temperature structure of the very outer parts of the photosphere (log tau_500=-3.8 and beyond) compared to a flux-constant, hydrostatic, standard MARCS model photosphere. Our new model is consistently calculated including chemical equilibrium and radiative transfer from the given temperature structure. Possible reasons for a temperature decrease in the outer-most parts of the photosphere and the assumed break-down of the assumptions made in classical model-atmosphere codes are discussed.Comment: To appear in ApJ.

Progressive Acceleration of Insulin Exposure Over 7 Days of Infusion Set Wear

Insulin exposure varies over 3 days of insulin infusion set (IIS) wear making day-to-day insulin dosing challenging for people with diabetes (PWD). Here we report insulin pharmacodynamic (PD) and pharmacokinetic (PK) data extending these observations to 7 days of IIS wear. PWD (A1C ≤8.5%, C-peptide tmax (P \u3c 0.001), Cmax (P \u3c 0.05), and mean residence time (P \u3c 0.0001). Area under the insulin concentration curve (AUC0–300) declined by ∼24% from days 0 to 7 (P \u3c 0.05). These results confirm/extend previous observations showing progressive acceleration of insulin exposure over IIS wear time. This may have implications for PWD and designers of closed-loop algorithms, although larger studies are necessary to confirm this. The study was registered in clinicaltrials.gov (NCT04398030)

Bcl-2 protein family: Implications in vascular apoptosis and atherosclerosis

Apoptosis has been recognized as a central component in the pathogenesis of atherosclerosis, in addition to the other human pathologies such as cancer and diabetes. The pathophysiology of atherosclerosis is complex, involving both apoptosis and proliferation at different phases of its progression. Oxidative modification of lipids and inflammation differentially regulate the apoptotic and proliferative responses of vascular cells during progression of the atherosclerotic lesion. Bcl-2 proteins act as the major regulators of extrinsic and intrinsic apoptosis signalling pathways and more recently it has become evident that they mediate the apoptotic response of vascular cells in response to oxidation and inflammation either in a provocative or an inhibitory mode of action. Here we address Bcl-2 proteins as major therapeutic targets for the treatment of atherosclerosis and underscore the need for the novel preventive and therapeutic interventions against atherosclerosis, which should be designed in the light of molecular mechanisms regulating apoptosis of vascular cells in atherosclerotic lesions

What are the basic self-monitoring components for cardiovascular risk management?

<p>Abstract</p> <p>Background</p> <p>Self-monitoring is increasingly recommended as a method of managing cardiovascular disease. However, the design, implementation and reproducibility of the self-monitoring interventions appear to vary considerably. We examined the interventions included in systematic reviews of self-monitoring for four clinical problems that increase cardiovascular disease risk.</p> <p>Methods</p> <p>We searched Medline and Cochrane databases for systematic reviews of self-monitoring for: heart failure, oral anticoagulation therapy, hypertension and type 2 diabetes. We extracted data using a pre-specified template for the identifiable components of the interventions for each disease. Data was also extracted on the theoretical basis of the education provided, the rationale given for the self-monitoring regime adopted and the compliance with the self-monitoring regime by the patients.</p> <p>Results</p> <p>From 52 randomized controlled trials (10,388 patients) we identified four main components in self-monitoring interventions: education, self-measurement, adjustment/adherence and contact with health professionals. Considerable variation in these components occurred across trials and conditions, and often components were poorly described. Few trials gave evidence-based rationales for the components included and self-measurement regimes adopted.</p> <p>Conclusions</p> <p>The components of self-monitoring interventions are not well defined despite current guidelines for self-monitoring in cardiovascular disease management. Few trials gave evidence-based rationales for the components included and self-measurement regimes adopted. We propose a checklist of factors to be considered in the design of self-monitoring interventions which may aid in the provision of an evidence-based rationale for each component as well as increase the reproducibility of effective interventions for clinicians and researchers.</p

The MCL-1 BH3 helix is an exclusive MCL-1 inhibitor and apoptosis sensitizer

available in PMC 2011 February 3.MCL-1 has emerged as a major oncogenic and chemoresistance factor. A screen of stapled peptide helices identified the MCL-1 BH3 domain as selectively inhibiting MCL-1 among the related anti-apoptotic Bcl-2 family members, providing insights into the molecular determinants of binding specificity and a new approach for sensitizing cancer cells to apoptosis.National Institutes of Health (U.S.) (NIH award 5RO1GM084181)National Institutes of Health (U.S.) (NIH grant 5P01CA92625)National Institutes of Health (U.S.) (Ruth L.
