We investigated the role of muscarinic receptor subtypes in calcium sensitization and their contribution to rho-kinase (ROK) and protein kinase C (PKC) pathways in carbachol (CCh)-induced contraction of human detrusor smooth muscle (DSM). α-toxin-permeabilized human DSM strips were prepared and mounted horizontally to record isometric force. The roles of M(2) ...

Ra-223, an α-particle emitting bone-seeking radionuclide, has recently been used in clinical trials for osseous metastases of prostate cancer. We investigated the relationship between absorbed fraction-based red marrow dosimetry and cell level-dosimetry using a model that accounts for the expected localization of this agent relative to marrow cavity architecture. We ...

L: -Serine is usually produced from glycine. We have genetically engineered Escherichia coli to produce L: -serine from glucose intracellularly. D: -3-Phosphoglycerate dehydrogenase (PGDH, EC 1.1.1.95) in E. coli catalyzes the first committed step in L: -serine formation but is inhibited by L: -serine. To overcome this feedback inhibition, both ...

Induced pluripotent stem cells (iPSCs) are rapidly evolving into an important research tool due to their close resemblance with pluripotent embryonic stem cells (ESCs). Of particular interest at this point are iPSC applications in disease modeling and drug discovery/testing. The high mobility group AT-hook 2 (HMGA2) protein is a nonhistone ...

Endometriosis is a chronic disease caused by the presence of endometrial tissue in ectopic locations outside the uterus. Chronic exposure to the environmental pollutant dioxin has been correlated with an increased incidence in the development of endometriosis in non-human primates. We have therefore examined whether there is an association between ...

Nitric oxide (NO) is a short-lived, diatomic, lipophilic gas that plays an integral role in defending against pathogens. Among its many functions are involvement in immune cell signaling and in the biochemical reactions by which immune cells defend against bacteria, fungi, viruses and parasites. NO signaling directs a broad spectrum ...

Psoriasis is a common, relapsing inflammatory skin disease characterized by erythematous scaly plaques. Histological manifestations of psoriasis include keratinocyte dysregulation and hyperproliferation, elongated rete ridges, and inflammatory infiltrates consisting of T cells, macrophages, dendritic cells, and neutrophils. Despite the availability of new effective drugs to treat psoriasis, the underlying mechanisms ...

The importance of early identification and intervention for children with autism spectrum conditions (ASC) has been established. However, there are often considerable delays from initial concern (by parent or professional) to diagnosis. Little is known about parents' experiences of primary care in the pre-diagnosis period. To identify feasible improvements to ...

Sodium-glucose co-transporters (SGLTs) have a key role in the re-absorption of glucose in the kidneys. Therefore, inhibition of SGLTs may provide a novel therapeutic strategy for diabetes mellitus. SGLT2 inhibitors enhance renal glucose excretion by inhibiting renal glucose re-absorption and reduce plasma glucose level, as well as they decrease the ...

A total of twelve novel enantiomerically pure tetra-carbohydrazide cyclophane macrocycles have been synthesised in quantitative yields by reacting chiral (4R,5R)- and (4S,5S)-1,3-dioxolane-4,5-dicarbohydrazides with aromatic bis-aldehydes in a [2 + 2]-cyclocondensation reaction. The compounds show a dynamic behaviour in solution, which has been rationalized in terms of an unprecedented conformational interconversion between two ...

Hodgkin lymphoma (HL) is one of the most common types of non-AIDS-defining tumors in the HIV-infected. Its incidence however seems to have increased under highly active anti-retroviral therapy (HAART). HIV-HL is a different entity from HL in HIV-negative subjects with a poorer prognosis that is associated with tumor-subtype, EBV-infection, and ...

Noles and Gelman (2012) attempt to critically reevaluate the claim that linguistic labels affect children's judgments of visual similarity. They report results of an experiment that used a modified version of Sloutsky and Fisher's (2004) task and conclude that "labels do not generally affect children's perceptual similarity judgments; rather, children's ...

Some observational studies have established an association between exposure to nonsteroidal anti-inflammatory drugs (NSAIDs) and a decreased risk of subsequently developing Alzheimer's disease (AD). Mild cognitive impairment or cognitive impairment, not dementia (CIND) is more likely to convert to AD, and no specific preventive method is currently available. The objective ...

Among other mechanisms, behavioral and cognitive development entail, on the one hand, contextual scaffolding and, on the other hand, neuromodulation of adaptive neurocognitive representations across the life span. Key brain networks underlying cognition, emotion, and motivation are innervated by major transmitter systems (e.g., the catecholamines and acetylcholine). Thus, the maturation ...

Nicotinic acetylcholine receptor (AChR) channels at neuromuscular synapses rarely open in the absence of agonists, but many different mutations increase the unliganded gating equilibrium constant (E0) to generate AChRs that are active constitutively. We measured E0 for two different sets of mutant combinations and by extrapolation estimated E0 for wild-type ...

RATIONALE: Previously, we showed that pioglitazone exerts its antidepressant-like effect through peroxisome proliferator-activated receptor gamma receptors and demonstrated the possible involvement of calcium-dependent nitric oxide synthase inhibitors. Based upon the in vitro results, pioglitazone reduces N-methyl-D: -aspartate (NMDA)-mediated calcium currents in hippocampal neurons. OBJECTIVE: In this study, we evaluated the ...

Transcatheter aortic valve implantation (TAVI) is increasingly used to treat patients with aortic stenosis who are considered to be too high-risk for surgical replacement of the aortic valve. Although the procedural risks are decreasing, the occurrence of new conduction abnormalities remains a vexing issue. Both left bundle branch block and ...

As a peroxisome proliferator-activated receptor alpha (PPARα) agonist, fenofibrate favorably modulates dyslipidemia and inflammation markers, which are associated with cardiovascular risk. To determine whether variation in the PPARα receptor gene was associated with lipid and inflammatory marker response, we conducted a 3-week trial of fenofibrate in 861 men and women. ...

Koen and Yonelinas (2010; K&Y) reported that mixing classes of targets that had short (weak) or long (strong) study times had no impact on ʐROC slope, contradicting the predictions of the encoding variability hypothesis. We show that they actually derived their predictions from a mixture unequal-variance signal detection (UVSD) model, ...

T lymphocyte arrest within microvasculature is an essential process in immune surveillance and the adaptive immune response. Integrins and chemokines coordinately regulate when and where T cells stop under flow via chemokine-triggered inside-out activation of integrins. Diacylglycerol kinases (DGKs) regulate the levels of diacylglycerol (DAG) which in turn determine the ...

Abstract Objective. A maxillary complete denture has been a common prosthetic treatment for people with edentulous maxillas. The fracture and deformation of dentures are recurrent and common problems for denture-wearers. Consequently, reinforcement materials are embedded in the denture base to prevent fracture and deformation. The purpose of this study was ...
