Mycobacterial infections, including multidrug and extreme drug-resistant (MDR and XDR) infections, are a severe challenge and create a virtual antibiotic-deficient era. Bacterial transcription is an established antimicrobial drug target. In mycobacteria, efficient transcription termination relies on the ATP-dependent RNA helicase factor Rho. Rho factor is essential for Mycobacterium tuberculosis (Mtb) survival, and is a valid antibacterial drug target with no homolog in eukaryotes. Rho maintains genomic stability and virulence and prevents pervasive transcription in Mtb. In this review, we provide an overview of the essentiality of Rho in Mtb, which makes it an attractive drug target for inhibitor discovery.

Interventions to Maintain HIV/AIDS, Tuberculosis, and Malaria Service Delivery During Public Health Emergencies in Low- and Middle-Income Countries: Protocol for a Systematic Review.

Background: Although existing disease preparedness and response frameworks provide guidance about strengthening emergency response capacity, little attention is paid to health service continuity during emergency responses. During the 2014 Ebola outbreak, there were 11,325 reported deaths due to the Ebola virus and yet disruption in access to care caused more than 10,000 additional deaths due to measles, HIV/AIDS, tuberculosis, and malaria. Low- and middle-income countries account for the largest disease burden due to HIV, tuberculosis, and malaria and yet previous responses to health emergencies showed that HIV, tuberculosis, and malaria service delivery can be significantly disrupted.

We developed a reversed-phased high-performance liquid chromatographic method combining ultraviolet detection and integrated pulsed amperometric detection for the simultaneous quantification of dopamine, 5-hydroxyindolacetic acid, homovanillic acid, serotonin, 3,4-dihydroxyphenylacetic acid, norepinephrine and epinephrine. All target components were completely separated in a C18 column with isocratic elution of 5% acetonitrile solution containing 8 mM HClO4 and 0.20 mM 1-octanesulfonic acid as an ion pairing reagent.

As a traditional Chinese medicine, Sanao decoction (SAD) has been used to treat chronic obstructive pulmonary disease (COPD) for multi-years. However, the potential mechanism and targets for its effects of SAD remain unknown. The 94 components of SAD were identified by UPLC-LTQ-Orbitrap MS.

Background: Iliopsoas injuries are a common cause of anterior hip and groin pain and can be successfully managed with conservative treatment. Corticosteroid and local anesthetic injections can also be offered in conjunction with nonoperative management. Given the variability in reported injection guidelines, composition, and techniques, the purpose of this study was to systematically review the literature to assess progression to surgery and patient outcomes following iliopsoas injections.

Arthritis leads to bone erosion due to an imbalance between osteoclast and osteoblast function. Our prior investigations revealed that the Ca-selective ion channel, Orai1, is critical for osteoclast maturation. Here, we show that the small-molecule ELP-004 preferentially inhibits transient receptor potential canonical (TRPC) channels.
