[EX Q]: Efavirenz is used for the antiretroviral treatment of HIV/tuberculosis-coinfected patients in developing countries. A switch to nevirapine is regularly carried out because of the cost and side effects of efavirenz. Pharmacokinetic studies suggested that nevirapine should be initiated at full dose when used as a substitute for efavirenz.', 'The aim of this study was to measure the cumulative incidence of adverse events (AEs) related to nevirapine in patients switched from efavirenz to immediate full-dose nevirapine (FDN).', 'In 2001 an antiretroviral treatment programme was initiated with the first-line regimen stavudine, lamivudine and efavirenz. In 2003, the fixed-dose combination of stavudine, lamivudine and nevirapine was recommended. Thus, first-line therapy was changed and FDN was initiated when patients were switched from efavirenz to nevirapine.', 'Between April and December 2004, 394 patients were switched from efavirenz to FDN. The cumulative incidence of AEs related to nevirapine was 13.2% [95% confidence interval (CI) 10.2-16.7] and that of severe AEs was 8.9% (95% CI 6.5-11.9). In women the incidence of AEs was 17.6% (95% CI 12.1-24.3) and that of severe AEs was 12.2% (95% CI 7.7-18.2).

[EX Q]: Phagocytes, especially monocytes, macrophages, and dendritic cells, play a pivotal role in the innate and adaptive immune responses during sepsis. We have shown that inhibition of histone deacetylase 6 improves survival and increases bacterial clearance in a mouse model of cecal ligation and puncture (CLP). The aim of this study was to determine whether this effect was associated with changes in the number and composition of different blood cell types in the circulation.', 'C57BL/6J mice were subjected to CLP, and 1\xa0h later given an intraperitoneal injection of either Tubastatin A dissolved in dimethyl sulfoxide, or dimethyl sulfoxide only. Sham-operated animals were treated in an identical fashion but not subjected to CLP. Forty-eight hours later, peripheral blood was obtained via cardiac puncture and analyzed using a HemaTrue veterinary hematology analyzer.', 'Tubastatin A administration increased the number of circulating monocytes in the sham-operated and the CLP animals. In comparison with the sham, CLP animals displayed an increase in the granulocyte percentage in white blood cells and decrease in the lymphocyte number and percentage, with a resultant increase in the granulocyte-to-lymphocyte ratio. Treatment of CLP animals with Tubastatin A decreased the granulocyte percentage and restored the lymphocyte number and percentage, which decreased the granulocyte-to-lymphocyte ratio. In the sham animals, Tubastatin A increased red blood cell number, hematocrit, and hemoglobin. This effect was not seen in CLP animals.

[EX Q]: The PINK1-Parkin pathway is known to play important roles in regulating mitochondria dynamics, motility, and quality control. Activation of this pathway can be triggered by a variety of cellular stress signals that cause mitochondrial damage. How this pathway senses different levels of mitochondrial damage and mediates cell fate decisions accordingly is incompletely understood.', 'Here, we present evidence that PINK1-Parkin has both cytoprotective and proapoptotic functions. PINK1-Parkin operates as a molecular switch to dictate cell fate decisions in response to different cellular stressors. Cells exposed to severe and irreparable mitochondrial damage agents such as valinomycin can undergo PINK1-Parkin-dependent apoptosis. The proapoptotic response elicited by valinomycin is associated with the degradation of Mcl-1. PINK1 directly phosphorylates Parkin at Ser65 of its Ubl domain and triggers activation of its E3 ligase activity through an autocatalytic mechanism that amplifies its E3 ligase activity toward Mcl-1.
