The important role of microfilaria (worms) in human and animal disease remains an area of key disagreement between the naturopathic and allopathic physicians. While microfilaria infections are rampart in undeveloped countries, they rarely rise to identification as a cause of disease in Western countries. New research studies in the diagnosis and treatment of SIBO (Small Intestinal Bacterial Overgrowth) and (IBD) Inflammatory Bowel Diseases of ulcerative colitis, Crohn's Disease and microcytic colitis may make both sides equally correct...

Following an oil spill in the marine environment, chemical dispersants, which increase oil droplet formation and distribution into the water column, are assumed to provide a net benefit to seabirds by reducing the risk of exposure to oil on the water surface. However, few data are available regarding acute, external impacts of exposure to dispersed oil. We evaluated the effects of known concentrations of dispersant and crude oil in artificial seawater on live Common Murres (Uria aalge). Waterproofing and microscopic feather geometry were evaluated over time and compared to pre-exposure values...

More than two billion people are latently infected with Mycobacterium tuberculosis. Most tuberculosis (TB)-subunit vaccines currently in various stages of clinical trials are designed for prevention of active TB, but not to prevent reactivation of latent TB-infection. Thus, there is an urgent need for an effective multi-stage vaccine based on early-expressed and latently-expressed antigens that prevents both acute and latent infections. Areas covered: Here, we reviewed the published pre-clinical and clinical studies of multi-stage subunit vaccines against TB, and the protective capacities of the vaccines were compared with BCG, either alone or in combination with different vaccine delivery systems/adjuvants...

Vaginal rings for pre-exposure prophylaxis are a female-initiated HIV prevention method that does not require daily or coitally-dependent dosing. As part of a randomized placebo-controlled trial of a tenofovir disoproxil fumarate intravaginal ring, we assessed product acceptability through in-depth interviews with 18 women during and after 14 days of continuous use. Women reported that the ring was comfortable with few side effects, regardless of experimental arm. However, interest in future use by this cohort was modest for several reasons including: low self-perceived HIV risk; concern that use implied promiscuity; potential for interference with relationship formation and trust; concern for interference with menstruation and cleanliness; and worries about partners' acceptability and sexual pleasure...

Phthalates are widely used as plasticizers that influence sexual and reproductive development. Here, we investigated whether di-(2-ethylhexyl) phthalate (DEHP) affects macrophage polarization that are associated with tumor initiation and progression. No changes were observed in LPS- or ConA-stimulated in vitro spleen B or T cell proliferation for 48 h, respectively. In contrast, macrophage functions were inhibited in response to DEHP for 12 h as judged by LPS-induced H2O2 and NO production and zymosan A-mediated phagocytosis...

The associations between environmental lead exposure and high school educational outcomes in four communities located in New South Wales, Australia, were examined in this ecological study. A mixed model analysis was performed to account for each school's results being more similar than results for other schools. The effect of environmental lead exposure on mean results for five educational outcomes was examined. 'Leaded' schools with more than five per cent of students living in the highest lead risk areas were tested against non-leaded 'comparison' schools that were matched by a pre-defined socio-educational advantage rating...

BACKGROUND AND AIMS: Take-home naloxone can prevent death from heroin/opioid overdose, but pre-provision is difficult because naloxone is usually given by injection. Non-injectable alternatives, including naloxone nasal sprays, are currently being developed. To be effective, the intranasal (i.n.) spray dose must be adequate but not excessive, and early absorption must be comparable to intramuscular (i.m.) injection. We report on the pharmacokinetics (PK) of a specially produced concentrated novel nasal spray...

Occupational lung diseases are an important public health issue and are avoidable through preventive interventions in the workplace. Up-to-date knowledge about changes in exposure to occupational hazards as a result of technological and industrial developments is essential to the design and implementation of efficient and effective workplace preventive measures. New occupational agents with unknown respiratory health effects are constantly introduced to the market and require periodic health surveillance among exposed workers to detect early signs of adverse respiratory effects...

OBJECTIVE: While pre-exposure prophylaxis with oral tenofovir (TFV) disoproxil fumarate/emtricitabine reduces HIV acquisition rates, poor adherence to and acceptability of daily vaginal gels has led to development of vaginal film formulations to improve adherence and, potentially, enable episodic use. STUDY DESIGN: In this two-arm, cross-over study of a fast-dissolving tenofovir film (40 mg) compared to a previously studied semisolid tenofovir 1% gel (40 mg), 10 healthy women received a single vaginal dose of each study product...

Background Selective serotonin reuptake inhibitors (SSRI) may interfere with platelet function, and pre-stroke SSRI treatment has been associated with increased hematoma volumes and mortality in hemorrhagic stroke patients. The effects of SSRI on the risk of hemorrhagic complications after thrombolysis in ischemic stroke patients are unclear. Aims To examine the effects of pre-stroke SSRI exposure on bleeding complications, functional outcome, and mortality following thrombolysis in ischemic stroke. Methods Data including standard demographic and clinical variables as well as baseline and follow-up stroke severity (measured by National Institutes of Health Stroke Score), functional outcome (measured by modified Rankin Scale) at 3 months, and mortality at 7 and 90 days were extracted from the Virtual International Stroke Trials Archive...

Frost and heat events can be challenging for sessile organisms that cannot escape thermal extremes. However, adverse effects of thermal stress on fitness may be reduced by pre-exposure to cold or heat, a process known as acclimation. To understand the ecological and evolutionary implications of acclimation, we investigated (1) the reduction in performance due to stress pre-exposure, (2) the magnitude of increased leaf resistance to subsequent stress, (3) the costs of acclimation, and (4) the genes differing in expression due to stress pre-exposure...

PURPOSE: Triple-negative breast cancers (TNBC) lack expression of three common cell surface receptors, i.e., estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER2). Accordingly, TNBCs are associated with fewer treatment options and a relatively poor prognosis. Having screened a National Cancer Institute natural compound library, the purpose of this study was to investigate the bioactivity of compound C4 (Crassin) in TNBC cells. METHODS: Cell viability assays were performed in two TNBC cell lines, MDA-MB-231 and 4T1, following C4 treatment in the presence or absence of the antioxidant N-acetyl-L-cysteine (NAC)...

Studies examining student motivation levels suggest that this is a significant factor in students' engagement in physical education and may be positively affected when teachers employ alternative pedagogical models such as game-centered approaches (GCAs). The aim of this study was to investigate changes in self-determined motivation of students as they participated in a GCA-basketball unit taught using the Tactical Games Model (TGM). Participants were 173 students (84 girls), 79 middle school (45 girls) and 94 (39 girls) elementary school students from four seventh and five fourth/fifth grade co-educational classes...

There is no antiviral treatment available once clinical disease following rabies virus infection has initiated. Considered a neglected tropical disease, >60,000 human rabies deaths are estimated each year despite the availability of pre- and post-exposure prophylaxis for pre-immunisation or administration following a potential exposure before the onset of clinical disease. Such post-exposure treatments include administration of rabies immunoglobulin (RIG) and vaccination at a distant site to prime a humoral immune response...

Trichloroethylene (TCE), a prevalent environmental contaminant, is a potent renal and hepatic toxicant through metabolites such as S-(1, 2-dichlorovinyl)-l-cysteine (DCVC). However, effects of TCE on other target organs such as the placenta have been minimally explored. Because elevated apoptosis and lipid peroxidation in placenta have been observed in pregnancy morbidities involving poor placentation, we evaluated the effects of DCVC exposure on apoptosis and lipid peroxidation in a human extravillous trophoblast cell line, HTR-8/SVneo...

RATIONALE: Reinforcement-enhancing effects of nicotine occur in human subjects and laboratory rats. However, the doses used in animal studies typically exceed smoking-associated levels of exposure, and generalized behavioral activation by nicotine can potentially confound data interpretation. METHODS: During daily 60-min sessions, male adult rats pressed an "active" lever to illuminate a brief cue light. Pressing on either the active or inactive lever retracted both levers for 60 s...
