The passive electrical properties of synthetic strands of cardiac muscle, grown in tissue culture, were studied using two intracellular microelectrodes: one to inject a rectangular pulse of current and the other to record the resultant displacement of membrane potential at various distances from the current source. In all preparations, the potential displacement, instead of approaching a steady...

The current interpretation of the controversial and dynamic nature literature reports in this area leads me to lean towards preference a standard DNa+ upper range (138 mEq/L) international utilization clinical directors Brazil. My opinion individualize (plus minus 2 mmol/L prescription) would be based on clinically relevant signals excessive interdialytic weight gain uncontrolled hypertension (...

The rate of unidirectional uptake, v, of L-[4,5-3H]leucine was studied in 17 isolated dog brains by means of an indicator-dilution technique using 22Na as the intravascular reference. The arterial leucine concentration was varied in increments by adding unlabeled leucine to the blood and v was determined after each change. The valine and isoleucine concentrations were varied independently to pe...

On examination she had densely fused labia minora extending anteriorly from posterior fourchette and partially occluding the introitus (Figure 1). The following new surgical technique was used to treat her. She was prescribed oestrogen cream for local application. During the follow up of two years there was no recurrence. A new method of surgical treatment for recurrent labial adhesions in a pr...

The functional significance of water channels in wheat (Triticum aestivum L.) root membranes was assessed using light scattering to measure vesicle shrinking in response to osmotic gradients rapidly imposed in a stopped flow apparatus. Vesicles were obtained from both a plasma membrane fraction and a plasma membrane-depleted endomembrane fraction including tonoplast vesicles. Osmotic water perm...

Increasing numbers of girls and young women are seeking medical attention due to concerns about the appearance of their external genitalia. One particular area of concern is hypertrophic labia minora, which remains a poorly defined clinical diagnosis. Once it was considered a variant of normal anatomy, but in recent times, increasing numbers of health care providers are being consulted for labi...
