The actin cytoskeleton executes a broad range of essential functions within a living cell. The dynamic nature of the actin polymer is modulated to facilitate specific cellular processes at discrete locations by actin-binding proteins (ABPs), including the formins and tropomyosins (Tms). Formins nucleate actin polymers, while Tms are conserved dimeric… (More)
One major limitation in the expression of eukaryotic proteins in bacteria is an inability to post-translationally modify the expressed protein. Amino-terminal acetylation is one such modification that can be essential for protein function. By co-expressing the fission yeast NatB complex with the target protein in E.coli, we report a simple and widely… (More)
BACKGROUND Approximately 28.5 million people living with HIV are eligible for treatment (CD4<500), but currently have no access to antiretroviral therapy. Reduced serum level of micronutrients is common in HIV disease. Micronutrient supplementation (MNS) may mitigate disease progression and mortality. OBJECTIVES We synthesized evidence on the effect of… (More)

People living with human immunodeficiency virus frequently use dietary supplements, including probiotics, but concern exists about ingesting live organisms. We performed a systematic review of the benefits of probiotics and a meta-analysis of sepsis risk. We undertook a protocol-driven, comprehensive review to identify all relevant studies, assess their… (More)
Fentanyl iontophoretic transdermal system (ITS) [IONSYS®, The Medicines Company, Parsippany, NJ, USA] is a needle-free, patient-controlled, postoperative opioid pain management treatment. It is indicated for the short-term management of acute postoperative pain in adults requiring opioid analgesia in the hospital. The safety and effectiveness of fentanyl… (More)
