The behavior of micropollutants in water treatment is an important aspect in terms of water quality. Non-target screening by liquid chromatography coupled to high-resolution mass spectrometry (LC-HRMS) offers the opportunity to comprehensively assess water treatment processes by comparing the signal heights of all detectable compounds before and after treatment. Without preselection of known target compounds, all accessible information is used to describe changes across processes and thus serves as a measure for the treatment efficiency...

Infectious diseases have been found to be a major cause of mortality in fish hatcheries. Probiotics have been introduced to replace antibiotics commonly used for treatment of bacterial infection in aquaculture. This study was conducted to isolate, screen, and evaluate the probiotic Bacillus spp. for potential use as a feed supplement to enhance fish growth, disease resistance and innate immunity of Pla-mong Pangasius bocourti. Bacillus aerius strain B81e was selectively isolated from the intestine of healthy catfish and chosen based on its probiotic properties both in vitro and in vivo...

Background: Childhood diarrheal diseases remain highly endemic in India, but the emergence of extended-spectrum β-lactamase (ESBL)-producing Escherichia coli among children with diarrhea in Bihar remains elusive. In this study, we determine and characterize ESBL-producing E coli pathotypes among hospitalized diarrheal preschool children living in low socioeconomic level communities in Bihar, India. Materials and methods: The stool samples were collected everyday throughout the year for 2 consecutive years...

As the detection of the first outbreak of a novel aetiological agent of rabbit haemorrhagic disease commonly called RHDV2 or RHDVb (Lagovirus europaeus/GI.2, henceforth GI.2) in France in 2010, the virus rapidly spread throughout continental Europe and nearby islands such as Great Britain, Sardinia, Sicily, the Azores and the Canary Islands among others. The outbreaks of this new lagovirus cause important economic losses in rabbitries, and ecological disruptions by affecting the conservation of rabbit-sensitive top predators...

This research set out to identify compounds from marine sponges that can act as bacterial virulence blockers. Extracts from a total of 80 sponges collected from throughout Indonesia were screened in a high-throughput NF-κB-based screen that identifies compounds capable of inhibiting the bacterial type III secretion system (T3SS) in Yersinia pseudotuberculosis. An extract that was shown to inhibit T3SS-driven NF-κB expression was obtained from an Iotrochota cf. iota sponge and was the source of seven new bromo- and iodo-containing compounds, all of which contain a 2-(4-oxyphenyl)ethan-1-amine core...

The NUDIX enzymes are involved in cellular metabolism and homeostasis, as well as mRNA processing. Although highly conserved throughout all organisms, their biological roles and biochemical redundancies remain largely unclear. To address this, we globally resolve their individual properties and inter-relationships. We purify 18 of the human NUDIX proteins and screen 52 substrates, providing a substrate redundancy map. Using crystal structures, we generate sequence alignment analyses revealing four major structural classes...

BACKGROUND: Unconditional cash transfers (UCTs; provided without obligation) for reducing poverty and vulnerabilities (e.g. orphanhood, old age or HIV infection) are a type of social protection intervention that addresses a key social determinant of health (income) in low- and middle-income countries (LMICs). The relative effectiveness of UCTs compared with conditional cash transfers (CCTs; provided so long as the recipient engages in prescribed behaviours such as using a health service or attending school) is unknown...

BACKGROUND: Anaplasma marginale is an important tick-transmitted rickettsial pathogen of cattle, with worldwide distribution and an important economic impact. The genetic diversity of A. marginale strains has been extensively characterized in different geographical regions throughout the world, while information is limited on studies in China. This study was carried out to determine the prevalence and genetic diversity of A. marginale strains in cattle from ten provinces of China. METHODS: A total of 557 blood samples from cattle were collected and screened for the occurrence of A...

The Wisconsin State Laboratory of Hygiene challenged Wisconsin laboratories to examine their biosafety practices and improve their culture of biosafety. 103 clinical and public health laboratories completed a questionnaire-based, microbiology-focused biosafety risk assessment. Greater than 96% of respondents performed activities related to specimen processing, direct microscopic examination, and rapid non-molecular testing, while approximately 60% performed culture interpretation. Although important to assessing risk, data specific to patient occupation, symptoms, and travel history were often unavailable to the laboratory and, therefore, less contributory to microbiology biosafety risk assessment than information relative to specimen source and test requisition...

Background: Alcohol screening and brief intervention (SBI) in trauma patients has been reported in literature to be effective in changing harmful drinking patterns and injury recurrence. Despite good evidence that SBI can benefit patients and provide a more holistic care, it is not routinely implemented in acute medical settings in Australia, in particular emergency departments (EDs). Objective: This paper aims to assess the knowledge, confidence, and practice of alcohol SBI in trauma patients by emergency physicians throughout Australia and New Zealand through an online survey...

PURPOSE: Chemotherapy-induced nausea and vomiting (CINV) causes significant morbidity among colorectal cancer patients, receiving fluorouracil, oxaliplatin, and leucovorin (FOLFOX) chemotherapy even with standard antiemetic prophylaxis. The purpose of this study is to determine if the addition of aprepitant to standard antiemetic therapy improves CINV in these patients. METHODS: Patients receiving FOLFOX for colorectal cancer were given antiemetic prophylaxis with aprepitant 125 mg orally on day 1 and 80 mg on days 2 and 3...

Due to advances in the fields of stem cell biology and cellular engineering, a variety of commercially available human-derived neurons and neural progenitor cells (NPCs) are now available for use in research applications, including small molecule efficacy or toxicity screening. The use of human-derived neural cells is anticipated to address some of the uncertainties associated with the use of nonhuman culture models or transformed cell lines derived from human tissues. Many of the human-derived neurons and NPCs currently available from commercial sources recapitulate critical process of nervous system development including NPC proliferation, neurite outgrowth, synaptogenesis, and calcium signaling, each of which can be evaluated using high content image analysis (HCA)...

Scuticociliatosis is a devastating and intractable protozoal disease in olive flounder, leading to a significant loss throughout the year. This study aimed to investigate a systemically effective antiscuticociliatosis agent for olive flounder for better absorption into the infected internal organs. The in vitro and in vivo antiscuticociliatosis effects of clioquinol (CQ) were examined after screening 30 biocidal agents against the highly pathogenic scuticociliate Miamiensis avidus. CQ was the most potent in vitro drug of those tested against cultured M...

REVIEW
Bradley D Becker
INTRODUCTION: Techniques and armamentarium for intentional replantation have varied throughout the years with no universally accepted clinical treatment guidelines. A wide range of success rates has been reported, and accordingly, this treatment method has often been regarded as a treatment of last resort. However, recent studies have shown more consistent success rates as high as 88% to 95%. In light of these new studies, intentional replantation may now be considered a more commonly accepted treatment modality...
