Effects of a Blend of Trisodium Citrate, Creatine Monohydrate, Leucine, and Blueberry Extract on Training-Induced Changes in Leg Extension Strength, Endurance, and Muscle Size.

Although creatine monohydrate (CM), leucine, and polyphenols have been independently researched, there is a lack of research on the effects of a supplementation blend containing trisodium citrate, CM, leucine, and blueberry extract (TCLB) on muscle strength, endurance, and size. This study compared the effects of 8 wk of supplementation with TCLB versus CM and placebo (PLA) combined with resistance training on leg extension strength, endurance, and muscle size. Twenty-eight recreationally active men ingested either TCLB ( = 10), CM ( = 10), or PLA ( = 8) during 8 wk of resistance training.

The effects of phosphocreatine disodium salts plus blueberry extract supplementation on muscular strength, power, and endurance.

Background: Numerous studies have demonstrated the efficacy of creatine supplementation for improvements in exercise performance. Few studies, however, have examined the effects of phosphocreatine supplementation on exercise performance. Furthermore, while polyphenols have antioxidant and anti-inflammatory properties, little is known regarding the influence of polyphenol supplementation on muscular strength, power, and endurance.

Robust suppression of HIV replication by intracellularly expressed reverse transcriptase aptamers is independent of ribozyme processing.

RNA aptamers that bind human immunodeficiency virus 1 (HIV-1) reverse transcriptase (RT) also inhibit viral replication, making them attractive as therapeutic candidates and potential tools for dissecting viral pathogenesis. However, it is not well understood how aptamer-expression context and cellular RNA pathways govern aptamer accumulation and net antiviral bioactivity. Using a previously-described expression cassette in which aptamers were flanked by two "minimal core" hammerhead ribozymes, we observed only weak suppression of pseudotyped HIV.

Bioactive A-type proanthocyanidins from Cinnamomum cassia.

Two trimeric proanthocyanidins, cinnamtannin B-1 (1) and cinnamtannin D-1 (2), have been isolated from the bark of Cinnamomum cassia along with the known tetramer parameritannin A-1 (3) and a previously unreported tetramer, named cassiatannin A (4). The structures of 1-4 were elucidated on the basis of 1D and 2D NMR, MS, and CD analyses and compared to the reported data. Proanthocyanidins (1-4) possess significant in vitro inhibitory activity against cyclooxygenase-2 (COX-2) at micromolar concentrations.

EspR, a key regulator of Mycobacterium tuberculosis virulence, adopts a unique dimeric structure among helix-turn-helix proteins.

EspR is a transcriptional regulator that activates the ESX-1 secretion system during Mycobacterium tuberculosis infection and is critical for pathogenesis. It is unique among DNA-binding proteins as it is secreted as part of a feedback regulatory loop that serves to mitigate transcriptional activity. Here we report the crystal structure of a functional EspR dimer at 2.

The effects of ProAlgaZyme novel algae infusion on metabolic syndrome and markers of cardiovascular health.

Background: Metabolic Syndrome, or Syndrome X, is characterized by a set of metabolic and lipid imbalances that greatly increases the risk of developing diabetes and cardiovascular disease. The syndrome is highly prevalent in the United States and worldwide, and treatments are in high demand. ProAlgaZyme, a novel and proprietary freshwater algae infusion in purified water, has been the subject of several animal studies and has demonstrated low toxicity even with chronic administration at elevated doses.

Can a concentrated cranberry extract prevent recurrent urinary tract infections in women? A pilot study.

Background: Urinary tract infections (UTIs) are extremely prevalent and despite treatment with antibiotics, reoccurrences are common causing frustration in the patient and the potential for developing antibiotic resistance. The use of cranberry products to prevent UTIs has recently become popular and more clinical studies are needed to explore this use.

Objective: This open label pilot study examined the ability of a concentrated cranberry preparation to prevent UTIs in women with a history of recurrent infections.
