Tissue renewal is an ongoing process in the epithelium of the skin. We have begun to examine the genetic mechanisms that control stem/progenitor cell activation in the postnatal epidermis. The conserved Hippo pathway regulates stem cell turnover in arthropods through to vertebrates. Here we show that its downstream effector, yes-associated ...

Antihypertensive therapy is aimed at improving vascular and cardiac health, as well as lowering blood pressure (BP). The benefit of such drugs in untreated patients with borderline BP has not been demonstrated. Subjects with BPs 130 mm Hg systolic or 85 mm Hg diastolic and at least one additional risk factor were randomly assigned ...

ABSTRACT: BACKGROUND: Chemoradiation is the standard treatment for anal cancer. 3D conformal radiotherapy (3D-CRT) is usually split in 2 sequences with a therapeutic break (gap) in between. Intensity-modulated radiation therapy (IMRT) makes it possible to reduce treatment time by abandoning this gap. The purpose of this study was to compare ...

BACKGROUND: Altered cerebral vasomotor reactivity leading to vasospasm can be seen both in patients with primary headache disorders (PHD) and in patients with subarachnoid hemorrhage (SAH). The pathogenesis of vasospasm in post-SAH patients and in headache disorder sufferers may be related. To address this hypothesis, we analyzed a large cohort ...

In two experiments, we investigated emergent conditional relations in pigeons using a symbolic matching-to-sample task with temporal stimuli as the samples and hues as the comparisons. Both experiments comprised three phases. In Phase I, pigeons learned to choose a red keylight (R) but not a green keylight (G) after a ...

Computational models of diseased arteries are advancing rapidly, and a need exists to develop more accurate material models of human atherosclerotic plaques. However, intact samples for in vitro mechanical testing are not readily available. Most plaque samples are harvested from carotid endarterectomies where the geometries are not suitable for the ...

Abstract Conclusion: Nasal polyposis (NP) is frequently found to run in families. Earlier onset of the condition strongly suggested the genetic basis for the development of NP and implied that it might be a genetic disease involving multiple genes. Objective: The etiology and pathogenesis of NP remain largely unknown, although ...

In the last few years, the treatment of castration-resistant prostate carcinoma (CRPC) has changed completely. The approval of docetaxel and subsequent investigation in this field have led to development of new agents that have demonstrated an improvement in overall survival in the post-docetaxel setting, such as cabazitaxel and abiraterone. Radium-223 ...

Stroke is a leading cause of disability, and the number of stroke survivors continues to rise. Traditional neurorehabilitation strategies aimed at restoring function to weakened limbs provide only modest benefit. New brain stimulation techniques designed to augment traditional neurorehabilitation hold promise for reducing the burden of stroke-related disability. Investigators discovered ...

Water and nutrient availability are the major limiting factors of biological activity in arid and semiarid ecosystems. Therefore, perennial plants have developed different ecophysiological adaptations to cope with harsh conditions. The chemical profile of the root exudates varies among plant species and this can induce variability in associated microbial populations. ...

Most gibbons dwell in the tropical forests of Southeastern Asia, but eastern hoolock gibbons (Hoolock leuconedys) survive in high montane forest ranging from 1,600 to 2,700 m a.s.l. in Gaoligongshan (>24°30'N), Yunnan, China. To assess the behavioral adaptations of hoolock gibbons to the montane forest, we related temperature and food availability ...

Clinical laboratory tests have no value if clinicians cannot quickly order and obtain the results they need. We found that efforts to obtain even the most commonly ordered tests are often derailed by excessively complex nomenclature. Ordering the right laboratory tests is critical to diagnosis and treatment, but existing mechanisms ...

Streptococcal throat infection is associated with a specific variant of psoriasis and with HLA-Cw6 expression. In this study, activation of circulating psoriatic cutaneous lymphocyte-associated antigen (CLA)(+) memory T cells cultured together with epidermal cells occurred only when streptococcal throat extracts were added. This triggered the production of Th1, Th17, and ...

Although chloroplast transcriptional and translational mechanisms were derived originally from prokaryote endosymbionts, chloroplasts retain comparatively few genes as a consequence of the overall transfer to the nucleus of functions associated formerly with prokaryotic genomes. Various modifications reflect other evolutionary shifts toward eukaryotic regulation such as posttranscriptional transcript cleavage with individually ...

Invariant natural killer T (iNKT) cells expressing a CD1d-restricted invariant αβTCR have key regulatory roles in autoimmunity, pathogen immunity, and tumor surveillance, but their function in the control of allergic skin diseases remains poorly documented. Using a model of contact hypersensitivity (CHS) to the hapten DNFB, we show here that ...

The ducts associated with sperm transport from the testicular lobules to the Wolffian ducts in Ambystoma maculatum were examined with transmission electron microscopy. Based on the ultrastructure and historical precedence, new terminology for this network of ducts is proposed that better represents primary hypotheses of homology. Furthermore, the terminology proposed ...
