Sustanon is a well-known anabolic drug that is used to treat hypogonadism and restore muscle mass and bone density. As research to date has been limited to its effects in glycolytic fibers, this study aimed to investigate the dose-related effects of Sustanon on the oxidative fibers of avian skeletal muscle. Adult female chickens were randomly divided into 4 groups: control (C), received a dose of 100 μl normal saline per injection; and Sustanon-1, -2, and -3 (S1, S2, and S3), that received a dose of 12.5, 25, or 50 mg/kg Sustanon per injection, respectively...

Traumatic brain injury (TBI) is the predominant cause of mortality in young adults and children living in China. TBI induces inflammatory responses; in addition, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-6 are important pro-inflammatory cytokines. Considering the observation that Hsp-70 overexpression can exert neuroprotection, identifying a drug that is able to induce the upregulation of Hsp70 has the potential to be a promising therapy for the treatment of neurological diseases. Thus, the present study assessed the clinical effectiveness of an anticancer drug and Hsp70 activator, 17-allylamino-demethoxygeldanamycin (17-AAG), to evaluate its potential as a treatment for patients with TBI...

In the development of a drug for intra-articular administration, a sustained-release formulation is desirable since it is difficult to sustain the effects of conventional injections due to fast drug leakage from the joint cavity. In this study, we prepared sustained release gel formulations for intra-articular administration containing indocyanine green (ICG) as a model drug to follow its fate after intra-articular administration in rats with IVIS. ICG administered as an aqueous solution leaked from the joint cavity in a short time and was excreted out of the body within a day...

Aurora kinase B, playing a vital, important role in mitosis, is frequently detected to be overexpressed in many cancer cell lines and various tumor tissues, including prostatic carcinoma. Given the essential function of Aurora kinase B in mitosis and its association with tumorigenesis, it might be a drug target for prostatic carcinoma treatment. In our study, short hairpin RNA targeting Aurora kinase B was cloned into a pGPU6 plasmid vector and then transfected into human prostatic carcinoma cells. The expression level of Aurora kinase B was verified by reverse transcription-polymerase chain reaction and Western blot...

Ankylosing spondylitis (AS) and axial spondyloarthritis (ax SpA) are chronic inflammatory diseases mainly involving the axial skeleton. Pharmacological treatments for AS and ax SpA usually include local glucocorticoid injections, NSAIDs and anti-TNFa agents. Since around 30% to 40% of patients are non responders or intolerant to anti-TNFa agents, we need new therapeutic options for AS and ax SpA. Areas covered: This review describes the new biological agents that can be used or are in development for AS or ax SpA as well as emerging synthetic targeted drugs...

People who inject drugs (PWID) in India are at high risk for HIV, with women being at elevated risk. Using a socio-ecological framework, this study assessed whether factors associated with HIV transmission risk behaviors differed across men and women PWID. Data for this cross-sectional study were collected from 6449 PWID in 7 cities in Northeast India. Men (n = 5653) and women (n = 796) PWID were recruited using respondent-driven sampling (RDS). We assessed sex differences in two recent HIV transmission risk behaviors: multiple sex partners and needle/syringe sharing...

BACKGROUND: Promoting arousal by manipulating certain brain regions and/or neurotransmitters has been a recent research focus, with the goal of trying to improve recovery from general anesthesia. The current study tested the hypothesis that a single subanesthetic dose of ketamine during isoflurane anesthesia would increase cholinergic tone in the prefrontal cortex and accelerate recovery. METHODS: Adult male rats were implanted with electroencephalography electrodes (frontal, parietal, and occipital cortex) and a microdialysis guide cannula targeted for the prefrontal cortex...

Nicolau syndrome, also known as embolia cutis medicamentosa or livedo-like dermatitis, is a sudden tissue necrosis, a rare complication of intramuscular injection of some drugs. We report a case of a 6-month-old girl who received intramuscularly the third dose of hexavalent vaccine (DTaP- HVB-IPV/HIb), and immediately presented a livedoid lesion around the injection site, progressing to necrosis. We reinforce the importance of early diagnosis to perform a suitable treatment and clinical follow-up to avoid ischemic secondary complications...

Scott D McVicar, Kempaiah Rayavara, Darrell H Carney
TP508 is a synthetically derived tissue repair peptide that has previously demonstrated safety and potential efficacy in phase I/II clinical trials for the treatment of diabetic foot ulcers. Recent studies show that a single injection of TP508 administered 24 h after irradiation significantly increases survival and delays mortality in murine models of acute radiation mortality. Thus, TP508 is being developed as a potential nuclear countermeasure. Because of the short plasma half-life of TP508, we hypothesize that increasing the peptide bioavailability would increase TP508 efficacy or reduce the dosage required for therapeutic effects...

The study examined trends in injection risk behaviors among people who inject drugs (PWIDs) and assessed the impact of harm reduction programs in Ukraine during 2007-2013. We performed a secondary analysis of the data collected in serial cross-sectional bio-behavioral surveillance surveys administered with PWIDs in Ukraine in 2007, 2008, 2011, and 2013. Using data from 14 Ukrainian cities, we assessed short-term trends in injection risk behaviors with the Cochran-Armitage test for trend and multivariable logistic regression models, adjusted for age, sex, region, marital status, education level, occupation, age at injection drug use initiation, experience of overdose, and self-reported HIV status...

PURPOSE: Sprays from pressurised metered-dose inhalers are produced by a transient discharge of a multiphase mixture. Small length and short time scales have made the investigation of the governing processes difficult. Consequently, a deep understanding of the physical processes that govern atomisation and drug particle formation has been elusive. METHODS: X-ray phase contrast imaging and quantitative radiography were used to reveal the internal flow structure and measure the time-variant nozzle exit mass density of 50 µL metered sprays of HFA134a, with and without ethanol cosolvent...

BACKGROUND: Local drug delivery devices offer a promising method for delivering vancomycin and amikacin for musculoskeletal wounds. However, current local delivery devices such as beads and sponges do not necessarily allow for full coverage of a wound surface with eluted antibiotics and do not address the need for reducing the antibiotic diffusion distance to help prevent contamination by bacteria or other microorganisms. We blended chitosan/polyethylene glycol (PEG) pastes/sponges to increase biocompatibility and improve antibiotic coverage within the wound...
