BACKGROUND Cell-to-cell HIV spread through virological synapses proceeds in two steps, first HIV particles are rapidly transferred to target cells in a CD4-dependent manner and then coreceptor-dependent events allow for infection or death of single target cells and cell-to-cell fusion. METHODS 293T or MOLT cells producing HIV particles were cocultured(More)
OBJECTIVES To compare the results of treatment of peyronie's disease with propoleum, laser, and simultaneous propoleum-laser. METHODS Prospective research. Twenty-eight patients with Peyronie's disease from the hospitals Freyre de Andrade,Fajardo, Clinico Quirúrgico y Habana Campo were studied between May 2002 and August 2003. They were divided into three(More)
The purpose of the present study was to analyze the long-term regulation of renal bumetanide-sensitive Na+-K+-2Cl- cotransporter and thiazide-sensitive Na+-Cl- cotransporter gene expression during changes in NaCl and water metabolism. Male Wistar rats exposed to high or low NaCl intake, saline loading, dehydration, water loading, and furosemide(More)
Nephron tubular epithelium possesses the capacity of adaptation to any salt ingestion condition. The mechanism of adaptation is due in part to an increase in the activity of Na(+):K(+):ATPase at the basolateral membrane. The goal of the present study was to analyze the long-term regulation of the Na(+):K(+):ATPase alpha(1)-subunit mRNA expression during(More)
Some specific functions are often localized to unique cellular types or structures in organs such as kidney, brain, blood, and endocrine glands. As a result, it is not uncommon that gene products, although heavily expressed in some cell types within these organs, ultimately appear as low abundance products when total RNA is probed, resulting in decreased(More)
