Vaccinations and the controversy around them always go in parallel. We identified four categories blending in various amounts of truth and imagination: history, myths, shams and frauds. Over the years, they have alternated and sometimes transformed into one another. This sharp separation into categories is certainly academic and forced. In fact, the line between these aspects is not clear enough to allow a rigid and well-defined division. Our work starts from the category containing the most truthfulness: history, and goes on to analyze two categories that add fantasy to facts: myths and shams (or better, "old wives' tales")...

Costa Rica is a tropical country with one of the highest biodiversity on Earth. It also has an intensive agriculture, and pesticide runoff from banana and pineapple plantations may cause a high toxicity risk to non-target species in rivers downstream the plantations. We performed a first tier risk assessment of the maximum measured concentrations of 32 pesticides detected over 4 years in the River Madre de Dios (RMD) and its coastal lagoon on the Caribbean coast of Costa Rica. Species sensitivity distributions (SSDs) were plotted in order to derive HC5 values for each pesticide, i...

OBJECTIVES: To explore systemic effects of mutations in the UDP-N-acetylmuramoylalanyl-D-glutamate 2,6-diaminopimelate ligase (MurE) of Corynebacterium glutamicum, that leads to extracellular L-lysine accumulation by this bacterium. RESULTS: The analysis of a mutant cohort of C. glutamicum strains carrying all possible 20 amino acids at position 81 of MurE revealed unexpected effects on cellular properties. With increasing L-lysine accumulation the growth rate of the producing strain is reduced...

BACKGROUND: This is an update of a Cochrane review first published in 2003. Cervical dystonia is the most common form of focal dystonia and is a disabling disorder characterised by painful involuntary head posturing. There are two available formulations of botulinum toxin, with botulinum toxin type A (BtA) usually considered the first line therapy for this condition. Botulinum toxin type B (BtB) is an alternative option, with no compelling theoretical reason why it might not be as- or even more effective - than BtA...

Matrix metalloproteinases (MMPs) are an important family of zinc-containing enzymes with a central role in many physiological and pathological processes. Although several MMP inhibitors have been synthesized over the years, none reached the market because of off-target effects, due to the presence of a zinc binding group in the inhibitor structure. To overcome this problem non-zinc-binding inhibitors (NZIs) have been recently designed. In a previous article, a virtual screening campaign identified some hydroxynaphtyridine and hydroxyquinoline as MMP-2 non-zinc-binding inhibitors...

There has been growing interest in dynamic changes in the lexical processing system across trials, which have typically been assessed via linear mixed effect modelling. In the current study, we explore the influence of previous trial lexicality and previous trial perceptual degradation on the effect of lexicality and degradation on the current trial. The results of analyses of three datasets (two previously published studies and a new study) provide evidence for a robust four-way interaction among previous trial lexicality and degradation and current trial lexicality and degradation effects...

BACKGROUND: The effects of backpack load on young adults' gait parameters have received little attention. This author group previously reported that with a backpack load within 15% body weight, young adults maintain their gait parameters at the expense of increased exertion during a 6-minute walk at self-selected normal walking speed. However, the effect of backpack strap pattern on gait parameters during faster walking or longer stride length has not been evaluated. OBJECTIVE: To determine the effect of different backpack strap patterns on gait parameters during 12 minute duration walk test in young adults at self-selected normal and fast walking speeds...

PURPOSE: We aimed to evaluate the effects of preoperative urinary catheterization in nephrolithiasis treatment with extracorporeal shock wave lithotripsy (SWL). METHODS: Patients admitted to the Department of Pediatric Surgery for renal stones between June 2012 and June 2014 were evaluated retrospectively. Patients were divided into 2 groups based on JJ stent placements. Group 1 did not receive JJ stents, while group 2 did. The recorded demographic data for each group included age, gender, stone size, location, sessions, and complications...

This present study was aimed to investigate the molecular mechanisms involved in sevoflurane protection of hepatic ischemia-reperfusion (I/R) injury. Firstly, we investigated the protective effects of sevoflurane against hepatic I/R injury. Biochemical analysis results showed that sevoflurane preconditioning significantly protected against hepatic I/R injury by reducing liver enzymes and improving antioxidant defense markers. We also found that sevoflurane attenuates I/R-induced hepatic cell death, by TUNEL staining, DNA fragmentation ELISA and PARP activity determination...

Substantial attention has recently been devoted to G protein-biased agonism of the µ-opioid receptor (MOR) as an ideal new mechanism for the design of analgesics devoid of serious side effects. However, designing opioids with appropriate efficacy and bias is challenging because it requires an understanding of the ligand binding process and of the allosteric modulation of the receptor. Here, we investigated these phenomena for TRV-130, a G protein-biased MOR small-molecule agonist that has been shown to exert analgesia with less respiratory depression and constipation than morphine, and that it is currently being evaluated in human clinical trials for acute pain management...

PURPOSE: High-flow nasal cannula (HFNC) oxygen therapy is attracting increasing interest in acute medicine as an alternative to standard oxygen therapy; however, its use to prevent hypoxaemia after major abdominal surgery has not been evaluated. Our trial was designed to close this evidence gap. METHODS: A multicentre randomised controlled trial was carried out at three university hospitals in France. Adult patients at moderate to high risk of postoperative pulmonary complications who had undergone major abdominal surgery using lung-protective ventilation were randomly assigned using a computer-generated sequence to receive either HFNC oxygen therapy or standard oxygen therapy (low-flow oxygen delivered via nasal prongs or facemask) directly after extubation...

BACKGROUND: A large number of caregivers in Uganda rely on the private drug delivery sector to manage childhood illnesses such as malaria. In rural settings where the formal private sector is scarce, unlicensed retail drug outlets are an important initial source of care for households. Despite their abundance, little is known about them. This study explores unlicensed retail drug outlet vendors' perceptions of their practice and social environment in one rural district of Uganda. MATERIALS AND METHODS: A qualitative design using semi-structured interviews was conducted with vendors from unlicensed retail drug outlets across all 10 sub-counties of Butaleja District...

BACKGROUND: Although evidence points to a strong link between illicit drug use and crime, robust evidence for temporal order in the relationship is scant. We carried out a systematic review to assess the evidence for pathways through opiate/crack cocaine use and offending to determine temporal order. METHODS: A systematic review sourced five databases, three online sources, bibliographies and citation mapping. Inclusion criteria were: focus on opiate/crack use, and offending; pre-drug use information; longitudinal design; corroborative official crime records...

Lipid binders have traditionally been determined in paintings by using gas chromatography/mass spectrometry (GC/MS) to identify the characteristic profiles and ratios of fatty acids . However, the presence of mixtures in contemporary and modern oil paints makes the GC/MS determination of fatty acids insufficient to fully characterize the lipid binding media. In this study we prove that triacylglycerol (TAG) profiling by high-performance liquid chromatography with high-resolution tandem mass spectrometry, using ESI in positive and negative ionization modes is highly effective...

BACKGROUND: Little is known about the effectiveness of Housing First (HF) among ethnic minority groups, despite its growing popularity for homeless adults experiencing mental illness. This randomized controlled trial tests the effectiveness of a HF program using rent supplements and intensive case management, enhanced by anti-racism and anti-oppression practices for homeless adults with mental illness from diverse ethnic minority backgrounds. METHODS: This unblinded pragmatic field trial was carried out in community settings in Toronto, Canada...

OBJECTIVE Achondroplasia (ACH) is the most common short-limbed skeletal dysplasia caused by gain-of-function mutations in the fibroblast growth factor receptor 3 (FGFR3) gene. Foramen magnum stenosis (FMS) is one of the serious neurological complications in ACH. Through comprehensive drug screening, the authors identified that meclozine, an over-the-counter drug for motion sickness, inhibited activation of FGFR3 signaling. Oral administration of meclozine to the growing ACH mice promoted longitudinal bone growth, but it did not prevent FMS...
