Testosterone declines with aging, so most midlife women have "low" testosterone levels. Because libido also declines with aging, and distressing sexual problems peak at midlife, should midlife women with low libido and associated distress be treated with testosterone? This Practice Pearl reports clinical trial evidence, reviews the risks, and explains how testosterone might be used in a clinica...

Phagocytosis and intracellular killing of Staphylococcus aureus by granulocytes were examined in diabetic patients. There was no significant difference in the phagocytic activity of granulocytes between control and diabetic-subjects. However, intracellular killing by granulocytes was significantly reduced in insulin-treated diabetic patients compared with control subjects. No significant differ...

Although quantum dots (QDs) have provided invaluable information regarding the diffusive behaviors of postsynaptic receptors, their application in presynaptic terminals has been rather limited. In addition, the diffraction-limited nature of the presynaptic bouton has hampered detailed analyses of the behaviors of synaptic vesicles (SVs) at synapses. Here, we created a quantum-dot based presynap...

This study was conducted to identify the characteristics and mobility of debris flows analyze performance a berm as flow mitigation measure. The velocity, depth, Froude number, resistance coefficients, ratio were accordingly determined using results flume tests. To influence berm, for straight channel test without compared with those single-berm test. velocity observed increase increasing slope...

nonenzymatic glycation of low density lipoprotein (ldl) is a reaction of glucose and other reducing sugars with apolipoprotein b100 (apo-b100) lysine residues. in diabetes, this reaction is greatly accelerated and is important in the pathogenesis of diabetic complications. the objective of this study was to investigate in vitro effects of ?-tocopherol, ascorbic acid and lycopene on ldl glycatio...

C60-based organic thin film transistors (OTFTs) with high electron mobility and high operational stability are achieved with (111) oriented C60 films grown by using template effects of diindenoperylene (DIP) under layer on the SiO2 gate insulator. The electron mobility of the C60 transistor is significantly increased from 0.21 cm V 1 s 1 to 2.92 cm V 1 s 1 by inserting the template-DIP layer. M...

1. Oxidized glutathione reacts or interacts with some erythrocytic enzymes (glucose 6-phosphate dehydrogenase, EC 1.1.1.49, aspartate aminotransferase, EC 2.6.1.10) but not with some others (lactate dehydrogenase, EC 1.1.1.27). 2. GSSG does not diminish the activity of any of these enzymes and is therefore not responsible for the decreased enzyme activities associated with older erythrocytes. 3...

A primary focus of longevity research is to identify prognostic risk factors that can be mediated by early treatment efforts. To date, much of this work has focused on understanding the biological processes that may contribute to aging process and age-related disease conditions. Although such processes are undoubtedly important, no current biological intervention aimed at increasing health and ...

Upon cold and drought stress, sucrose and trehalose protect membrane structures from fusion and leakage. Similarly, these sugars protect membrane proteins from inactivation during dehydration. We studied the interactions between sugars and phospholipid membranes in giant unilamellar vesicles with the fluorescent lipid analog 3,3'-dioctadecyloxacarbocyanine perchlorate incorporated. Using fluore...
