Conventional wastewater treatment technologies are ineffective for remediation of old LandFill Leachate (LFL), and innovative approaches to achieve satisfactory removal of this recalcitrant fraction are needed. This study focused on old LFL treatment with a selected fungal strain, Bjerkandera adusta MUT 2295, through batch and continuous tests, using packed-bed bioreactors under non-sterile conditions. To optimize the process performance, diverse types of co-substrates were used, including milled cellulose from beverage cups waste material...

PURPOSE OF REVIEW: This review summarizes current knowledge of the role of the lung microbiome in interstitial lung disease and poses considerations of the microbiome as a therapeutic target. RECENT FINDINGS: Although historically considered sterile, bacterial communities have now been well documented in lungs in health and disease. Studies in idiopathic pulmonary fibrosis (IPF) suggest that increased bacterial burden and/or abundance of potentially pathogenic bacteria may drive disease progression, acute exacerbations, and mortality...

Dental Personnel (DP) may be exposed to pathogens during dental treatment, either through contact contaminated equipment, or with blood and respiratory secretion. On the other hand, health care professionals are constantly exposed to pathogens and opportunists in their work environment. Consequently, the dental healthcare environment is connected with the risk of exposure to biological agents both for patients and dental workers, and involves a wide number of microorganisms that can be present in biological matrices (gingival fluids, saliva, blood), contaminated and/or non-sanitized surfaces, water used in the dental unit, or emitted by patients suffering or carrier of a transmissible disease...

In this study we tested a new approach to facilitate the application of white rot fungi (WRF) under non-sterile conditions, by introducing grain sorghum as carrier and sole carbon and nutrient source for WRF. To this end, Trametes versicolor was immobilized on sorghum, and its ability to remove humic acid (HA) from synthetic and real industrial wastewater was studied. HA removal was measured as colour reduction and also analysed via size exclusion chromatography (SEC). Under sterile conditions, 80% colour removal was achieved for both synthetic and real wastewater using immobilized WRF on sorghum, without adding any additional carbon or nutrient sources...

BACKGROUND AND AIMS: Mucoid structures that coat the epithelium play an essential role in keeping the intestinal microbiota at a safe distance from host cells. Encroachment of bacteria into the normally almost-sterile inner mucus layer has been observed in inflammatory bowel disease and in mouse models of colitis. Moreover, such microbiota encroachment has also been observed in mouse models of metabolic syndrome, which are associated low-grade intestinal inflammation. Hence, we investigated if microbiota encroachment might correlate with indices of metabolic syndrome in humans...

A 83-year-old healthy female with no past medical history presented with persistent hemoptysis and respiratory failure. She was found to have a tracheal bronchus on bronchoscopy. Patient underwent pulmonary lavage and sterile irrigation. Patient was stable, but developed excessive hemoptysis which prompted a repeat, emergent, bronchoscopy was performed to advance the ET tube to isolate the left lung from the bleeding right lung. Despite the effort taken, the patient became pulseless from the hypoxia caused by blood spillover into the entire tracheobronchial field...

Understanding the earliest events in speciation remains a major challenge in evolutionary biology. Thus identifying species whose populations are beginning to diverge can provide useful systems to study the process of speciation. Drosophila aldrichi, a cactophilic fruit fly species with a broad distribution in North America, has long been assumed to be a single species owing to its morphological uniformity. While previous reports either of genetic divergence or reproductive isolation among different D. aldrichi strains have hinted at the existence of cryptic species, the evolutionary relationships of this species across its range have not been thoroughly investigated...

Heritable variation is essential for evolution by natural selection. In Neotropical army ants, the ecological role of a given species is linked intimately to the morphological variation within the sterile worker caste. Furthermore, the army ant Eciton burchellii is highly polyandrous, presenting a unique opportunity to explore heritability of morphological traits among related workers sharing the same colonial environment. In order to exploit the features of this organismal system, we generated a large genetic and morphological dataset and applied our new method that employs geometric morphometrics (GM) to detect the heritability of complex morphological traits...

CONTEXT: Postpartum family planning is a compelling concern of global significance due to its salience to unplanned pregnancies, and to maternal and infant health in developing countries. Yet, women face the highest level of unmet need for contraception in the year following a birth. A cost-effective way to inform women about their risk of becoming pregnant after the birth of a child is to integrate family planning counseling and services with maternal and infant health services. METHODS: We use recently collected survey data from 2733 women from six cities in Uttar Pradesh, India who had a recent birth (since 2011) to examine the role of exposure to family planning information at maternal and infant health visits on (1) any contraceptive use in the postpartum period, and (2) choice of modern method in the postpartum period...

Disorders of the central nervous system (CNS) represent increasing social and economic problems all over the world which makes the effective transport of drugs to the brain a crucial need. In the last decade, many strategies were introduced to deliver drugs to the brain trying to overcome the challenge of the blood brain barrier (BBB) using both invasive and non-invasive methods. Non-invasive strategy represented in the application of nanocarriers became very common. One of the most hopeful nanoscopic carriers for brain delivery is core-shell nanocarriers or polymeric micelles (PMs)...

Reuse of medical device is accepted worldwide. Benefits of reuse include not only cost saving but a favorable impact on environment. However, certain requirements should be met for reuse to be safe and effective. The devices, which can be reused, should be clearly defined, a meticulous process for dis-infection and sterilization followed and its functionality ascertained before use. Further, an appropriate consent should be obtained where necessary and the cost saving entailed should be directly passed on to the patient...

INTRODUCTION: Invasive pneumococcal disease (IPD) typically presents as bacterial pneumonia, meningitis or primary bacteraemia. However, Streptococcus pneumoniae can produce infection at any level of the body (endocarditis, arthritis, spontaneous bacterial peritonitis, etc.), which is also known as unusual IPD (uIPD). There are very limited data available about the clinical and microbiological profile of these uncommon manifestations of pneumococcal disease. Our aim was to analyse clinical forms, microbiological profile, epidemiology and prognosis of a cohort of patients with unusual invasive pneumococcal disease (uIPD)...

BACKGROUND: During functionality testing and packaging of reusable surgical instruments (RSI) for sterilisation, instruments are frequently touched. Considering the lack of standards relating to hand hygiene frequency and use of gloves in the sterilising service unit packing area, we aimed to determine the effect of hand hygiene and glove use on maintenance of RSI cleanliness. METHODS: Following manual and automated cleaning, Halsted-mosquito forceps were assessed for adenosine triphosphate (ATP), protein and microbial contamination after handling with gloved and ungloved but washed hands utilising an ATP surface swab test, bicinchoninic acid assay, and standard culture plate/broth, respectively...

Inhibitor of Apoptosis Proteins (IAPs) are critical regulators of cell death and survival pathways. Mice lacking cellular IAP (cIAP) 1 and either cIAP2 or X-linked IAP (XIAP) die in utero, and myeloid lineage-specific deletion of all IAPs causes sterile inflammation, but their role in the skin is unknown. We generated epidermal-specific IAPs deficient mice and found that combined genetic deletion of cIAP1 in keratinocytes and ubiquitous cIAP2 deletion (cIap1(EKO/EKO).cIap2(-/-)) caused profound skin inflammation and keratinocyte death, lethal by post-partum day 10...

Bovine mastitis is an important disease in the dairy industry, causing economic losses as a result of withheld milk and treatment costs. Several studies have suggested milk amyloid A (MAA) as a promising biomarker in the diagnosis of mastitis. In the absence of a gold standard for diagnosis of subclinical mastitis, we estimated the diagnostic test accuracy of a commercial MAA-ELISA, somatic cell count (SCC), and bacteriological culture using Bayesian latent class modeling. We divided intramammary infections into 2 classes: those caused by major pathogens (e...

The pesticide atrazine, its degradation products, and 2,6-dichlorobenzamide (BAM) are persistent in groundwater environment. We studied whether their dissipation can be enhanced with a mixture of a complex carbon source and zero-valent iron (ZVI) called EHC®. The application rates were 1.0% and 2.0% (by weight) in subsurface sediments slurries (atrazine 30mg/L), and 2.0% in 1.5m pilot-scale sediment columns with groundwater flowing through (atrazine 0.08, desethylatrazine DEA 0.03, BAM 0.02μg/L). In the slurries under aerobic conditions, atrazine of 0...
