Shellfish harvesting in intertidal areas is a widespread and economically important activity in many countries across West Africa. However, in some areas, there is virtually no information concerning the levels of contaminants (and other elements related to nutritional aspects) in the harvested species. We collected sediments and several individuals of the West African bloody cockle Senilia senilis and of the razor clam Tagelus adansoni during the dry season of 2015 nearby three islands in the Bijagós archipelago, Guinea-Bissau...

It is well known that high fluoride results in low fertility. Epididymis is the important place for spermatozoa maturation, which is essential for successful fertilization. In the previous studies, fluoride was reported to damage the epididymal structure of mouse and rabbit. However, the mechanism underlying sodium fluoride (NaF)-induced epididymal toxicity has not yet been well elucidated. The aim of this study is to explore the global protein alterations in epididymis of mice exposed to NaF using the iTRAQ technique...

OBJECTIVE: Pharmaceutical treatment of latent tuberculosis infection (LTBI) reduces the risk of progression to active tuberculosis (TB); however, poor adherence tempers the protective effect. We aimed to estimate the health burden of non-adherence, the maximum allowable cost of hypothetical new adherence interventions to be cost-effective and the potential value of existing adherence interventions for patients with low-risk LTBI in Canada. DESIGN: A microsimulation model of LTBI progression over 25 years...

Human SMOOTHENED (SMO) was identified by expression cloning as a new host factor that inhibits HIV-1 infection. Forced expression of SMO inhibited HIV-1 replication and infection with a single-round lentiviral vector, but not infection with a murine leukemia virus-based retroviral vector in human MT-4 T cells. Quantitative PCR analyses revealed that stable expression of SMO impaired formation of the integrated form of lentiviral DNA, but did not interrupt reverse transcription. This inhibition was evident in MT-4 and HUT102 human T cell lines expressing low levels of SMO mRNA, but not in SupT1 or Jurkat T cell lines expressing higher levels of SMO mRNA...

The WHO annually reports an increasing abuse of new psychoactive substances (NPS), which are a heterogeneous group of synthetic drugs and are consumed as substitute for controlled drugs of abuse. In this work, we focused on highly potent derivatives such those of phenethylamine (2C), N-2-methoxybenzyl phenethylamine (NBOMes), lysergic acid diethylamide (LSD), and fentanyl. Severe to fatal intoxications were described due to their high potency. Therefore, they have to be taken at very low doses resulting in low blood concentration in the low ng/mL range, which is a challenge for reliable analytical detection and quantification...

INTRODUCTION: Impingement between the acetabular component and the iliopsoas tendon is a cause of anterior pain after total hip replacement (THR). Treatment can be non-operative, endoscopic or arthroscopic, or by open revision of the acetabular component. Few studies have assessed these options. The present study hypothesis was that endo/arthroscopic treatment provides rapid pain relief with a low rate of complications. METHODS: A prospective multicenter study included 64 endoscopic or arthroscopic tenotomies for impingement between the acetabular component and the iliopsoas tendon, performed in 8 centers...

INTRODUCTION: Emerging studies have implicated air pollution in the neurodegenerative processes. Less is known about the influence of air pollution, especially at the relatively low levels, on developing dementia. We conducted a population-based cohort study in Ontario, Canada, where the concentrations of pollutants are among the lowest in the world, to assess whether air pollution exposure is associated with incident dementia. METHODS: The study population comprised all Ontario residents who, on 1 April 2001, were 55-85years old, Canadian-born, and free of physician-diagnosed dementia (~2...

BACKGROUND: Hospital length of stay after acute myocardial infarction (AMI) treated with primary percutaneous coronary intervention (pPCI) has reduced, resulting in more limited patient education during admission. Therefore, systematic participation in cardiac rehabilitation (CR) has become more essential. We aimed to identify patient-related factors that are associated with participation in and completion of a CR programme. METHODS: We identified 3,871 consecutive AMI patients who underwent pPCI between 2003 and 2011...

BACKGROUND: Opioid abuse is a major problem around the world. Identifying environmental factors that contribute to opioid abuse and addiction is necessary for decreasing this epidemic. In rodents, environmental enrichment protects against the development of low dose stimulant self-administration, but studies examining the effect of enrichment and isolation (compared to standard housing) on the development of intravenous opioid self-administration have not been conducted. The present study investigated the role of environmental enrichment on self-administration of the short-acting μ-opioid remifentanil...

BACKGROUND: In the current era, trainees frequently use unvetted online resources for their own education, including viewing surgical videos on YouTube. While operative videos are an important resource in surgical education, YouTube content is not selected or organized by quality but instead is ranked by popularity and other factors. This creates a potential for videos that feature poor technique or critical safety violations to become the most viewed for a given procedure. METHODS: A YouTube search for "Laparoscopic cholecystectomy" was performed...

Osteogenesis imperfecta (OI) is typically characterized by low bone mass and increased bone fragility caused by heterozygous mutations in the type I procollagen genes (COL1A1/COL1A2). We report two cases of a 56-year-old woman and her 80-year-old mother who suffered from multiple vertebral and non-vertebral fractures with onset in early childhood. A full osteologic assessment including dual-energy X-ray absorptiometry (DXA), high-resolution peripheral quantitative computed tomography (HR-pQCT), and serum analyses pointed to a high bone mineral density (BMD) in the hip (DXA Z-score + 3...
