Thiocyanate (SCN(-) ) is a toxic compound that forms when cyanide (CN(-) ), used to recover gold, reacts with sulfur species. SCN(-) -degrading microbial communities have been studied, using bioreactors fed synthetic wastewater. The inclusion of suspended solids in the form of mineral tailings, during the development of the acclimatized microbial consortium, led to the selection of an active planktonic microbial community. Preliminary analysis of the community composition revealed reduced microbial diversity relative to the laboratory-based reactors operated without suspended solids...

Copper (Cu) is an essential metal for all living organisms, although it is toxic in excess. Filamentous fungus must acquire copper from its environment for growth. Despite its essentiality for growth, the mechanisms that maintain copper homeostasis are not fully understood in filamentous fungus. To gain insights into copper homeostasis, we investigated the roles of a copper transcription factor Afmac1 in the life-threatening fungus Aspergillus fumigatus, a homolog of the yeast MAC1. We observed that the Afmac1 deletion mutant exhibited not only significantly slower growth, but also incomplete conidiation including a short chain of conidia and defective melanin...

: Antiphospholipid antibodies (aPLs) are a heterogeneous group of autoantibodies essential for the diagnosis of antiphospholipid syndrome (APS) but do not predict clinical manifestations or disease progression. Hence, the co-presence of other antibodies may prove useful. Autoimmunity directed toward vimentin and other citrullinated peptides was established in rheumatoid arthritis (RA) and in other autoimmune conditions including systemic lupus erythematosus (SLE). We have previously described the presence of autoantibodies directed against vimentin/cardiolipin complex in patients with antiphospholipid syndrome (APS), but there are no data on the role of citrullinated vimentin in APS...

This paper reviews the changing status of goose populations in Scotland since the 1940s, and the changing policies and management activities employed over that time. The size of all goose populations has risen since the 1940s due to protection measures, changes in agriculture and levels of shooting, in the UK and elsewhere. The development of goose policies in response to public interest and pressures is described. Some changes in goose populations since 2000 can be linked to this policy development. Policy is now split between protective measures for some species and adaptive management approaches encompassing control measures for others...

We here review the collision risks posed by large-bodied, flocking geese to aircraft, exacerbated by recent major increases in northern hemisphere goose populations and air traffic volume. Mitigation of goose-aircraft strike risks requires knowledge of local goose movements, global goose population dynamics and ecology. Airports can minimise goose strikes by managing habitats within the airport property, applying deterrents to scare geese away and lethal control, but goose migration and movements at greater spatial scales present greater challenges...

Evolutionary analyses of the critical core promoter interval support a selective advantage for expanding the length of certain short tandem repeats (STRs) in humans. We recently reported genome-wide data on human core promoter STRs that are "exceptionally long" (≥6-repeats). Near the top of the list, the neuron-specific gene, RIT2, contains one of the longest GA-STRs at 11-repeats. In the present study, we analyzed the evolutionary implications of this STR across species. We also studied this STR in a sample of 2,143 Iranian human subjects that encompassed a number of neuropsychiatric disorders and controls...

RATIONALE: Research has shown that alcohol can have both detrimental and facilitating effects on memory: intoxication can lead to poor memory for information encoded after alcohol consumption (anterograde amnesia) and may improve memory for information encoded before consumption (retrograde facilitation). This study examined whether alcohol consumed after witnessing a crime can render individuals less vulnerable to misleading post-event information (misinformation). METHOD: Participants watched a simulated crime video...

The Human Immunodeficiency Virus (HIV) is an infectious agent that attacks the immune system cells. Without a strong immune system, the body becomes very susceptible to serious life threatening opportunistic diseases. In spite of the great progresses on medication and prevention over the last years, HIV infection continues to be a major global public health issue, having claimed more than 36 million lives over the last 35 years since the recognition of the disease. Monitoring, through registries, of HIV-AIDS cases is vital to assess general health care needs and to support long-term health-policy control planning...

Hyperglycemia and mitochondrial ROS overproduction have been identified as key factors involved in the development of diabetic nephropathy. This has encouraged the search for strategies decreasing glucose levels and long-term improvement of redox status of glutathione, the main antioxidant counteracting mitochondrial damage. Previously, we have shown that avocado oil improves redox status of glutathione in liver and brain mitochondria from streptozotocin-induced diabetic rats; however, the long-term effects of avocado oil and its hypoglycemic effect cannot be evaluated because this model displays low survival and insulin depletion...

Surgical re-implantation of the left coronary artery (LCA) is the treatment of choice in anomalous origin of left coronary artery from pulmonary artery (ALCAPA). Despite normalization of left ventricular function after surgery, residual coronary lesions or myocardial fibrosis may be found. The aim of this study was to detect regional left ventricular dysfunction predictive of coronary lesions or residual myocardial fibrosis using speckle tracking. We enrolled ten patients treated with surgical re-implantation of LCA for ALCAPA...

PURPOSE: Toll-like receptor 4 (TLR4) is a transmembrane receptor that mediates immune responses to exogenous and endogenous ligands. Previously, non-coding single nucleotide polymorphisms (SNPs) in the TLR4 gene were related to primary open angle glaucoma (POAG). This study was undertaken to investigate whether coding TLR4 Asp299Gly (rs4986790 A/G) and Thr399Ile (rs4986791 C/T) are associated with POAG in a Mexican population. METHODS: One hundred and eighty-seven unrelated Mexican patients with POAG (94 men and 95 women; mean age 66...

Fiix-prothrombin time (Fiix-PT) differs from traditional PT in being affected by reduced factor (F) II or FX only. In the randomized controlled Fiix-trial, patients on warfarin monitored with Fiix-PT (Fiix-warfarin patients) had fewer thromboembolisms (TE), similar major bleeding (MB) and more stable anticoagulation than patients monitored with PT (PT-warfarin patients). In the current Fiix-trial report we analyzed how reduced anticoagulation variability during Fiix-PT monitoring was reflected in patients with TE or bleeding...

Feather corticosterone (CORT) levels are increasingly employed as biomarkers of environmental stress. However, it is unclear if feather CORT levels reflect stress and/or workload in the wild. We investigated whether feather CORT represents a biomarker of environmental stress and reproductive effort in tree swallows (Tachycineta bicolor). Specifically, we examined whether individual state and investment during reproduction could predict feather CORT levels in subsequently moulted feathers and whether those levels could predict future survival and reproductive success...

What is fascinating in plants (true also in sessile animals such as corals and hydroids) is definitely their open and indeterminate growth, as a result of meristematic activity. Plants as well as animals are characterized by a multicellular organization, with which they share a common set of genes inherited from a common eukaryotic ancestor; nevertheless, circa 1.5 billion years of evolutionary history made the two kingdoms very different in their own developmental biology. Flowering plants, also known as angiosperms, arose during the Cretaceous Period (145-65 million years ago), and up to date, they count around 235,000 species, representing the largest and most diverse group within the plant kingdom...

In the present study, the effects of low-molecular-weight organic acids (OAs) on the toxicity of copper (Cu) to the earthworm Eisenia fetida (E. fetida) were investigated in a simulated soil solution. We exposed E. fetida to soil solution containing Cu and a variety of OAs (acetic acid, oxalic acid, citric acid, and EDTA). We found that the addition of OAs reduced the toxicity of Cu to E. fetida, where the reduction was strongest in EDTA and weakest in acetic acid. These compounds decreased the mortality rate of E...

Immunotherapies emerged as an alternative for cancer treatment, yet their clinical efficacies are still limited, especially in case of solid tumors. Myeloid immune cells, such as macrophages and myeloid-derived suppressor cells (MDSCs), are often hijacked by tumors and become pivotal inhibitors of antitumor immunity. Immunosuppressive functions of tumor-associated myeloid cells result from the activity of Signal Transducer and Activator of Transcription 3 (STAT3), a transcription factor with well-defined tumorigenic and tolerogenic roles in human cancers...

Pregnancy represents a time of rapid bodily change, which includes physical proportions, physiology and responsibility. At this context, maternal vitamin D stores have been the objective of extensive scientific research during the last decades, focusing on their potential effects on maternal an neonatal health. A growing body of observational studies indicated that maternal hypovitaminosis D (as defined by maternal 25-hydroxyvitamin D [25(OH)D] levels <20 ng/ml or <50 nmol/l) is a significant risk factor for adverse neonatal outcomes including asthma, multiple sclerosis and other neurological disorders...
