Clinical and experimental data suggest that androgen receptor (AR) signaling plays a role on body composition, glucose homeostasis and lipid metabolism. The effect of AR disruption on such parameters was not extensively investigated in human people. A group of young to middle-age adult women with complete androgen insensitivity syndrome (CAIS, n = 18, age 32.

We study theoretically the linear Saffman-Taylor instability for non-Newtonian fluids in a Hele-Shaw cell. After introducing the notion of generalized Newtonian fluid we calculate the associated Darcy's law. We derive the relation governing the growth rate of normal modes for a large class of non-Newtonian flows.

Patients And Methods: A total of 235 premenopausal women with pT1mic/pT1a breast cancer (n = 21), or intraepithelial neoplasia (IEN, n = 160), or 5-year Gail risk > or = 1.
A patient with first-degree atrioventricular (AV) block and pulmonary regurgitation underwent a transthoracic echocardiogram. Continuous wave Doppler interrogation of the pulmonic valve displayed a biphasic regurgitation pattern. A discussion of the potential mechanism underlying this pattern is presented.

The Arabidopsis AMT1 proteins mediate uptake of the ionic form of ammonium. AMT transport activity is controlled allosterically via a highly conserved cytosolic C terminus that interacts with neighboring subunits in a trimer.

Methods: QUS measurements of the radius and tibia and dual-energy x-ray absorptiometry (DXA) measurements of the lumbar spine and whole skeleton were obtained in 88 HIV-infected children and adolescents (aged 4.8-22.
Bones undergo intensive modeling during growth, a process involving both formation and resorption processes. Bone formation can be accurately monitored by measurements of bone-specific alkaline phosphatase (BAP) in serum. The lack of appropriate reference values has hampered the use of BAP in pediatric subjects.

Although ERK1/2 has been proposed as a common mediator of antidepressant action in naive rodents, it remains to be determined whether the ERK1/2 pathway plays a role in depressive disorder. Here, we investigated whether chronic restraint stress (14 days) and antidepressant treatment [desipramine (DMI), 10 mg/kg intraperitoneally] induce changes in animal behavior and hippocampal levels of phospho-ERK1/2 and its substrate phospho-cAMP response element-binding protein (CREB).

Methods: In a study of 27 331 healthy women with triglycerides
Objective: Congenital hyperinsulinism is the most common cause of persistent hypoglycemia in infancy (HI), leading to severe neurologic disabilities if not promptly treated. The recent application of positron emission tomography (PET)/computed tomography (CT) scanning with 18-fluoro-l-3,4 dihydroxyphenylalanine improved the ability to distinguish the two histopathologic forms of HI (focal and diffuse), whose differentiation heavily influences the therapeutic management of the patient.
Case Report: We describe the case of a patient presenting with severe hypoglycemia from infancy.
Background: Nuclear magnetic resonance (NMR) spectroscopy measures the number and size of lipoprotein particles instead of their cholesterol or triglyceride content, but its clinical utility is uncertain.
Methods And Results: Baseline lipoproteins were measured by NMR in 27 673 initially healthy women followed up for incident cardiovascular disease (n=1015) over an 11-year period. After adjustment for nonlipid risk factors, hazard ratios and 95% confidence intervals for the top versus the bottom quintile of NMR-measured lipoprotein particle concentration (measured in particles per liter) were 2.
Background/aim: In children with central precocious puberty (CPP), gonadotropin-releasing hormone (GnRH) analogue treatment has been associated with an increase in body mass index (BMI). We evaluated BMI and body composition in adolescents treated with GnRH analogue at their near final height to assess the long-term effects of therapy on these parameters.
Patients And Methods: We studied 20 patients (14.
Background: High-sensitivity C-reactive protein (hsCRP) testing is relatively inexpensive and has been shown to predict the risk of cardiovascular disease (CVD) and diabetes in multiple patient groups, including those treated with statin therapy. JUPITER (Justification for the Use of Statins in Primary Prevention: An Intervention Trial Evaluating Rosuvastatin) is a recently completed large multicenter randomized clinical trial that tested whether statin therapy should be given to apparently healthy individuals with lower LDL cholesterol (LDL-C) concentrations but increased hsCRP concentrations.
Content: This review discusses the literature on hsCRP in asymptomatic populations, analyzes it according to CVD and diabetes, and provides summary recommendations for the use of hsCRP in clinical practice.
Due to deleterious effects on non-target organisms, the use of organotin compounds on boat hulls of small vessels (<25 m) has been widely prohibited. The International Maritime Organisation (IMO) resolved that the complete prohibition on organotin compounds acting as biocides in antifouling systems should commence in 2008. As a result of restrictions on the use of organotin based paints, other antifouling formulations containing organic biocides have been utilised.

High-sensitivity assays that accurately measure levels of the inflammatory biomarker C-reactive protein have been proposed for use in assessments of risk for cardiovascular disease (CVD). A growing body of evidence supports recommendations for these tests in selected asymptomatic individuals deemed to be at intermediate risk of CVD according to traditional risk-factor assessments and who do not already warrant chronic treatment with aspirin and statin therapy. Data suggests that these high-sensitivity assays should be used in combination with measurements of LDL-cholesterol levels to assist risk stratification of selected patients for prevention of CVD.

Whether fasting status alters associations of nontriglyceride lipids with CVD is unclear.
Methods And Results: In a prospective study of 26 330 healthy women (19 983 fasting; 6347 nonfasting), associations of baseline lipids with incident CVD (754 fasting; 207 nonfasting) were examined over an 11-year follow-up.

Aim: To evaluate patient perception of the onset of action and overall satisfaction with a fast-dissolving tablet (FDT) formulation of ebastine in patients with intermittent or persistent allergic rhinitis.
Patients And Methods: This was a cross-sectional, multicenter, pharmacy-based survey involving adult patients (>18 years) with allergic rhinitis who presented with a prescription for ebastine FDT. Via a telephone interview, patients were asked to evaluate the characteristics of ebastine FDT in comparison with their previous experience with other antihistamines.
Neurological deficits in the offspring caused by human maternal hypothyroxinemia are thought to be irreversible. To understand the mechanism responsible for these neurological alterations, we induced maternal hypothyroxinemia in pregnant rats. Behavior and synapse function were evaluated in the offspring of thyroid hormone-deficient rats.

Therefore, the aim of this study was to evaluate whether CuSO4 neurotoxicity in vivo, which was evaluated by determining the contralateral rotation and loss of tyrosine hydroxylase immunostaining, was dependent on DT-diaphorase inhibition by dicoumarol.

A new fast-dissolving tablet (FDT) formulation of ebastine has been developed that dissolves rapidly in the mouth without the need for water. This new formulation of ebastine FDT offers an opportunity to tailor prescribing in a way that meets patient's preferences. The aim of the reported study was to evaluate the preferences of allergic rhinitis patients who were given either a placebo version of ebastine FDT or a placebo version of ebastine regular tablet (RT).
