The Gulf of Mexico is considered one of the world's major marine ecosystems, supporting important fisheries and habitats such as barrier islands, mangrove forests, seagrass beds, coral reefs etc. It also hosts a range of complex offshore petroleum exploration, extraction, and refining industries, which may have chronic or acute impacts on ecosystem functioning. Previous work on the marine effects of this activity is geographically incomplete, and has tended to focus on direct hydrocarbon impacts, while impacts from other related contaminants (e...

BACKGROUND: Each year it is estimated in the United States an approximate of 8 million fractures; 5 to 10% develop delayed union or absence of periosteal new bone. There are several factors that can cause delay in fracture healing, among the well known, is the use of prophylactic antithrombotic therapy for deep vein thrombosis (DVT). DVT appears in 40 to 60% of the patients undergoing orthopedic surgery without prophylactic antithrombotic therapy. The goal of this study was to assess whether there is a difference in time of bone healing in lower limb fractures (femur and tibia) comparing rivaroxaban to enoxaparin as the prophylactic antithrombotic management...

Background and Aims: To investigate the behaviour of miR-19a and miR-20a, two microRNAs involved in posttranscriptional modulation of TF expression in peripheral blood mononuclear cells (PBMCs) exposed to high glucose (HG) and lipopolysaccharide (LPS), and to evaluate the involvement of angiotensin II in that process. Methods: TF Procoagulant Activity (PCA, one-stage clotting assay), antigen (Ag, ELISA), and miR-19a and miR-20a levels (specific TaqMan® MicroRNA Assays) were evaluated in PBMCs exposed to high glucose (HG, 50 mM), LPS (100 ng/mL), and Olmesartan (OLM, 10-6 M), an angiotensin II type 1 receptor antagonist...

Beans of the species Theobroma cacao L., also known as cacao, are the raw material to produce chocolate. Colombian cacao has been classified as a fine flavor cacao that represents the 5% of cacao world's production. Colombian genetic resources from this species are conserved in ex situ and in-field germplasm banks, since T. cacao has recalcitrant seeds to desication and long-term storage. Currently, the collection of T. cacao of the Colombian Corporation of Agricultural Research (CORPOICA) has approximately 700 germplasm accessions...

Mycosis fungoides (MF) is the most frequent form of cutaneous T-cell lymphoma. The disease often takes an indolent course, but in approximately one third of the patients, the disease progresses to an aggressive malignancy with a poor prognosis. At the time of diagnosis, it is impossible to predict which patients develop severe disease and are in need of aggressive treatment. Accordingly, we investigated the prognostic potential of microRNAs (miRNAs) at the time of diagnosis in MF. Using a qRT-PCR platform, we analysed miRNA expression in diagnostic skin biopsies from 154 Danish patients with early-stage MF...

Although molecular rectifiers were proposed over four decades ago 1,2 , until recently reported rectification ratios (RR) were rather moderate 2-11 (RR ~ 101). This ceiling was convincingly broken using a eutectic GaIn top contact 12 to probe molecular monolayers of coupled ferrocene groups (RR ~ 105), as well as using scanning tunnelling microscopy-break junctions 13-16 and mechanically controlled break junctions 17 to probe single molecules (RR ~ 102-103). Here, we demonstrate a device based on a molecular monolayer in which the RR can be switched by more than three orders of magnitude (between RR ~ 100 and RR ≥ 103) in response to humidity...

ZTI-01 (fosfomycin for injection) is a broad spectrum antibiotic with a novel mechanism of action and is currently under development in the USA for treatment of complicated urinary tract infections. Globally, fosfomycin and polymyxin B are increasingly being used to treat multi-drug resistant Gram-negative infections. The objectives were to evaluate the pharmacodynamic activity of polymyxin B and fosfomycin alone and in combination against KPC-producing K. pneumoniae and to assess the rate and extent of emergence of resistance to different antibiotic regimens...

OBJECTIVE: To investigate whether the association between type 2 diabetes (T2D) and family history of diabetes is modified by the levels of physical activity in the Chilean population. METHOD: In this study were included 5129 participants from the cross-sectional 2009-2010 National Health Survey. Physical activity level was assessed using the Global Physical Activity Questionnaire and family history of T2D, through self-reporting. The association between diabetes, family history of diabetes and physical activity was determined using logistic regression...

The objective of this study was to evaluate the safety of 25-OH-D3 addition to the diet of bovine calves. The investigation was conducted as a feeding experiment for 90 days. 40 calves were allotted to four groups: T1 - control group which received 30 IU vitamin D3/kg feed, and three experimental groups, which received 25-OH-D3 in increasing dosages: T2 - 25-OH-D3 at 1.7 μg/kg, T3 - 25-OH-D3 at 5.1 μg/kg and T4 - 25-OH-D3 at 8.5 μg/kg. All calves in the four groups gained weight continually: no growth depression was observed...

OBJECTIVE: Severity of illness scores rest on the assumption that patients have normal physiologic values at baseline and that patients with similar severity of illness scores have the same degree of deviation from their usual state. Prior studies have reported differences in baseline physiology, including laboratory markers, between obese and normal weight individuals, but these differences have not been analyzed in the ICU. We compared deviation from baseline of pertinent ICU laboratory test results between obese and normal weight patients, adjusted for the severity of illness...

A retrospective cohort study, were evaluated: polymyxin B plus aminoglycosides or polymyxin B plus other antibiotics. Any degree of acute kidney injury occurred in 26 (86.6%) patients. The median time to acute kidney injury was 6.0 (95% CI 3-14) days in the polymyxin-aminoglycoside containing regimen group, against 27.0 (95% CI 6-42) days in the polymyxin with other antimicrobial combinations group (p=0.03). Polymyxin B with aminoglycosides group progressed faster to any degree of renal dysfunction.

Irisin, a novel myokine produced in response to physical exercise by skeletal muscle, displays anabolic effect on bone and can improve the bone-loss-induced osteoporosis in hind limb suspended mice. It is well known that muscles positively impact the skeleton and in different sports, including soccer, total body bone mineral density (TB-BMD) is elevated. Therefore, we have investigated the correlation between irisin serum levels and total and bone sub-regional BMD in soccer players never studied before. In this study, Caucasian football players of Bari team have been enrolled...

AIMS: Studies show that white men have a higher prevalence of Type 2 diabetes mellitus than women at a given age and BMI, but equivalent standardized data for other ethnic groups in the UK are sparse. METHODS: This cross-sectional study analysed UK Biobank data from 489 079 participants to compare the prevalence of diabetes mellitus across four major ethnic groups including: 471 700 (96.4%) white, 7871 (1.6%) South Asian, 7974 (1.6%) black and 1534 (0.3%) Chinese participants, before and after standardizing for age, socio-economic status (SES), BMI and lifestyle factors including physical activity, TV viewing, fruit and vegetable intake, processed meat, red meat, oily fish, alcohol intake and smoking...

OBJECTIVE: To report the use of virtual reality (VR) in pain intensity during dressing change of two burned children hospitalized in a Burn Treatment Center (BTC) in Southern Brazil. METHOD: Case report on the use of VR during dressing change of two burned children hospitalized in a BTC, from May to July 2016. For assessing pain, a facial pain rating scale was applied at four times: just before the dressing, during the dressing without the use of VR, during the dressing with the VR, and after the use of VR...
