We examined the availability and components of internet-based cognitive-behavioral therapies (iCBTs) for depression tested in randomized-controlled trials (RCTs). The objectives of this literature review were to determine the extent to which research-validated iCBTs were available to the public, as well as to determine their therapeutic content. A literature review of RCTs for iCBTs was conducted on July 30, 2021.

Background: and are pivotal genes driving increased risk for age-related macular degeneration (AMD) among several populations. Here, we performed a hospital-based case-control study to evaluate the effects of three single nucleotide polymorphisms (SNPs) among Hispanics from Mexico.

Materials And Methods: 122 cases and 249 controls were genotyped using Taqman probes.

and genes are traditional markers of increased risk of age-related macular degeneration (AMD) across populations. Recent findings suggest that additional genes-for instance, in the dystrophin-associated protein complex-might be promising markers for AMD. Here, we performed a case-control study to assess the effect of single nucleotide polymorphisms (SNPs), a member of this protein family, on AMD diagnosis and phenotype.

Mouse cardiac fibroblasts have been widely used as an in vitro model for studying fundamental biological processes and mechanisms underlying cardiac pathologies, as well as identifying potential therapeutic targets. Cardiac FBs are relatively easy to culture in a dish and can be manipulated using molecular and pharmacological tools. Because FBs rapidly decrease cell cycle division and proliferative rate after birth, they are prone to phenotypic changes and senescence in cell culture soon after a few passages.

Locally advanced breast cancer (LABC) cases have a varying five-year survival rate, mainly influenced by the tumor response to chemotherapy. Paclitaxel activity (response rate) varies across populations from 21.5% to 84%.

Several in vitro studies show that in animals and isolated cells, 17 beta-estradiol induces cardiovascular protective effects and it has also been observed that it reduces coronary heart disease risk. However, the use of estrogens to improve or protect cardiovascular function in humans has been controversial, this might be explained by the wide variety of effects, because estrogen receptors (ER) are expressed ubiquitously. Therefore, a cell-specific targeting therapeutic approach might be necessary.

It has been postulated that in blood vessels under alpha(1)-related stimulation, the endothelial intracellular calcium concentration ([Ca(2+)](i)) increases, which is necessary to induce nitric oxide synthesis, is the result of an increase in vascular smooth muscle, which subsequently, flows into the endothelial cells through gap junctions and it is not the result of a direct adrenergic stimulation of endothelial receptors. Others, however, postulate that endothelial alpha(1D)-adrenoceptors, have a direct effect on nitric oxide synthesis. In order to clarify this phenomena, in this work we analyzed the presence of alpha(1)receptor subtypes and their functional association with nitric oxide synthesis in rat coronary microvascular endothelial cells in culture, with pharmacological, immunological and reverse transcriptase polymerase chain reaction approaches.
