A novel and simple method for preparing magnetic biomass activated carbon (BAC) was developed. The BAC was prepared by decomposing fallen leaves, and magnetic nanoparticles were grown in situ on BAC using solvothermal method. The prepared magnetic BAC was characterized with FT-IR, XRD, vibrating sample magnetometer, thermo-gravimetric apparatus, SEM, and high-resolution transmission electron microscope, and results indicate that BAC and magnetic nanoparticles were combined together successfully. To investigate the adsorption ability of the composites, several dyes were selected as sample pollutants, and the sorbent showed high adsorption capacity for the dyes...

The insect juvenile hormone receptor is a basic helix-loop-helix (bHLH), Per-Arnt-Sim (PAS) domain protein, a novel type of hormone receptor. In higher flies like Drosophila, the ancestral receptor germ cell-expressed (gce) gene has duplicated to yield the paralog Methoprene-tolerant (Met). These paralogous receptors share redundant function during development but play unique roles in adults. Some aspects of JH function apparently require one receptor or the other. To provide a foundation for studying JH receptor function, we have recapitulated endogenous JH receptor expression with single cell resolution...

BACKGROUND: Alcohol is a well-known risk factor in unintentional drownings. Whereas psychotropic drugs, like alcohol, may cause psychomotor impairment and affect cognition, no detailed studies have focused on their association with drowning. Finland provides extensive post-mortem toxicological data for studies on drowning because of its high medico-legal autopsy rates. METHODS: Drowning cases, 2000 through 2009, for which post-mortem toxicological analysis was performed, came from the database of the Toxicological Laboratory, Department of Forensic Medicine, University of Helsinki, using the ICD-10 nature-of-injury code T75...

BACKGROUND: Identification of osteoporosis in women in order to prevent its related morbidity and mortality is considered a priority. Routine mammography is performed on all menopausal women as a screening tool. Determination of the relation between breast arterial calcification (BAC) on mammography and the bone density of this high-risk population could help us to determine those with osteoporosis. The aim of this study was to investigate the mentioned probable relation between BAC and osteoporosis...

Glycoprotein B (gB) is the conserved herpesvirus fusion protein, and it is required for the entry of herpesviruses. The structure of the postfusion conformation of gB has been solved for several herpesviruses; however, the gB prefusion crystal structure and the details of how the protein refolds from a prefusion to a postfusion form to mediate fusion have not been determined. Using structure-based mutagenesis, we previously reported that three mutations (I671A, H681A, and F683A) in the C-terminal arm of the gB ectodomain greatly reduced cell-cell fusion...

Children in foster care experience higher levels and rates of psychosocial difficulties than children from the general population. Governments and child welfare services have a responsibility to identify those children in care who have need for therapeutic services. This can be achieved through systematic screening and monitoring of psychosocial difficulties among all children in foster care. However, general screening and assessment measures such as the Strengths and Difficulties Questionnaire (SDQ) and Child Behavior Checklist (CBCL) might not adequately screen for the range of difficulties experienced by foster children...

Respiratory syncytial virus (RSV) is an enveloped, nonsegmented negative-strand RNA virus, which causes lower respiratory tract infections and is a leading cause of mortality in young infants. There is no available RSV vaccine and currently administered prophylactic antibodies are limited to high-risk populations. Current efforts to develop vaccines include development of live-attenuated RSV candidates. We describe here methods for preparation and recovery of recombinant RSV using an efficient bacterial artificial chromosome (BAC)-based system, expansion and plaque purification of recovered virus, and generation of master and working stocks...

OBJECTIVE: To examine the outcomes of trauma patients who tested positive for alcohol at the time of hospital arrival versus those who tested negative. METHODS: Data were pulled from the National Trauma Data Bank (2007-2010). All injured patients who were ≥14 years of age, sustained a "blunt" or "penetrating" injury, had complete systolic blood pressure (SBP) and heart rate (HR) records, were taken to a level 1 or 2 trauma center, and who received a confirmed blood alcohol test were included in the study...

Interspecific hybridization is a powerful tool for improvement of crop species, it has the potential to broaden the genetic base and create new plant forms for breeding programs. Synthetic allopolyploid is a widely-used model for the study of genetic recombination and fixed heterosis in Brassica. In Brassica napus breeding, identification and introgression of new sources of clubroot resistance trait from wild or related species into it by hybridization is a long-term crop management strategy for clubroot disease...

Balanced chromosomal aberrations have been shown to affect fertility in most species studied, often leading to hypoprolificacy (reduced litter size) in domestic animals such as pigs. With an increasing emphasis in modern food production on the use of a small population of high quality males for artificial insemination, the potential economic and environmental costs of hypoprolific boars, bulls, rams etc. are considerable. There is therefore a need for novel tools to facilitate rapid, cost-effective chromosome translocation screening...

Targeted delivery of anti-inflammatory osteoarthritis treatments have the potential to significantly decrease undesirable systemic side effects and reduce required therapeutic dosage. Here we present a targeted, non-invasive drug delivery system to decrease inflammation in an osteoarthritis model. Hollow thermoresponsive poly(N-isopropylacrylamide) (pNIPAM) nanoparticles have been synthesized via degradation of a N,N'-bis(acryloyl)cystamine (BAC) cross-linked core out of a non-degradable pNIPAM shell. Sulfated 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPSA) was copolymerized in the shell to increase passive loading of an anti-inflammatory mitogen-activated protein kinase-activated protein kinase 2 (MK2)-inhibiting cell-penetrating peptide (KAFAK)...

BACKGROUND: Aspects of impulsivity have been implicated in the development, or maintenance, of Alcohol Use Disorder (AUD). The brain dopamine system is implicated in both reward processing/memory (typically subcortical) and in brain inhibitory control mechanisms (typically cortical). Using a validated clinical lab paradigm, the dopamine/serotonin "stabilizing" drug, aripiprazole was evaluated in non-treatment-seeking AUD individuals based on their level of impulsivity/ self-control. METHODS: Ninety-nine individuals (77% male; mean age 27; 7...

Major depressive disorder (MDD), bipolar disorder (BD), and schizophrenia (SZ) are associated with cognitive dysfunction both in adulthood and in later life. In this study, we directly compared neurocognitive function between these three conditions in later life, employing stringent definitions of euthymia and symptomatic remission. Cognitive function in 60 elderly outpatients with MDD, BD, or SZ (20 patients per group) was assessed using the Japanese version of the Brief Assessment of Cognition in Schizophrenia...

This study evaluated the reliability and equivalency of three different potable reuse paradigms: (1) surface water augmentation via de facto reuse with conventional wastewater treatment; (2) surface water augmentation via planned indirect potable reuse (IPR) with ultrafiltration, pre-ozone, biological activated carbon (BAC), and post-ozone; and (3) direct potable reuse (DPR) with ultrafiltration, ozone, BAC, and UV disinfection. A quantitative microbial risk assessment (QMRA) was performed to (1) quantify the risk of infection from Cryptosporidium oocysts; (2) compare the risks associated with different potable reuse systems under optimal and sub-optimal conditions; and (3) identify critical model/operational parameters based on sensitivity analyses...

The striatum is the major component of the basal ganglia and is well known to play a key role in the control of motor function via balanced output from the indirect (iSPNs) and direct pathway striatal projection neurons (dSPNs). Little is known, however, about the molecular genetic mechanisms that control the formation of the iSPNs versus dSPNs. We show here that the SoxE family member, Sox8, is co-expressed with the dSPN marker, Isl1, in the developing striatum. Moreover, dSPNs, as marked by Isl1-cre fate map, express Sox8 in the embryonic striatum and Sox8-EGFP BAC transgenic mice specifically reveal the direct pathway axons during development...

Assembly of complex genomes using short reads remains a major challenge, which usually yields highly fragmented assemblies. Generation of ultra-dense linkage maps is promising for anchoring such assemblies, but traditional linkage mapping methods are hindered by the infrequency and unevenness of meiotic recombination that limit attainable map resolution. Here we develop a sequencing-based "in vitro" linkage mapping approach (called RadMap), where chromosome breakage and segregation are realized by generating hundreds of "subhaploid" fosmid/BAC clone pools, and by restriction site-associated DNA (RAD) sequencing of these clone pools to produce an ultra-dense whole-genome restriction map to facilitate genome scaffolding...

Dichloroacetonitrile (DCAN) is one of nitrogenous disinfection by-products (N-DBPs) with strong cytotoxicity and genotoxicity. In this study, the formation potential (FP) of DCAN was investigated in the samples of six important water sources located in the Yangtze River Delta. The highest formation concentration of DCAN was 9.05 μg/L in the water sample taken from Taihu Lake with the lowest SUVA value. After the NOM fractionation, the conversion rate of hydrophilic fraction to DCAN was found the highest. Subsequently, a waterworks using Taihu Lake as water source was chosen to research the FP variations of DCAN in the treatment process and backwash water...

BACKGROUND: Tilapias are the second most farmed fishes in the world and a sustainable source of food. Like many other fish, tilapias are sexually dimorphic and sex is a commercially important trait in these fish. In this study, we developed a significantly improved assembly of the tilapia genome using the latest genome sequencing methods and show how it improves the characterization of two sex determination regions in two tilapia species. RESULTS: A homozygous clonal XX female Nile tilapia (Oreochromis niloticus) was sequenced to 44X coverage using Pacific Biosciences (PacBio) SMRT sequencing...
