The moose (Alces alces) is a ruminant that harvests energy from fiber-rich lignocellulose material through carbohydrate-active enzymes (CAZymes) produced by its rumen microbes. We applied shotgun metagenomics to rumen contents from six moose to obtain insights into this microbiome. Following binning, 99 metagenome-assembled genomes (MAGs) belonging to 11 prokaryotic phyla were reconstructed and characterized based on phylogeny and CAZyme profile. The taxonomy of these MAGs reflected the overall composition of the metagenome, with dominance of the phyla Bacteroidetes and Firmicutes...

Wildlife conservation and management approaches typically focus on demographic measurements to assess population viability over both short and long periods. However, genetic diversity is an important predictor of long term population vitality. We investigated the pattern of change in genetic diversity in a large and likely isolated moose (Alces alces) population on Isle Royale (Lake Superior) from 1960-2005. We characterized samples, partitioned into five different 5-year periods, using nine microsatellite loci and a portion of the mtDNA control region...

The present study investigated the genetic contribution to alcohol dependence (AD) using genome-wide association data from three German samples. These comprised patients with: (i) AD; (ii) chronic alcoholic pancreatitis (ACP); and (iii) alcohol-related liver cirrhosis (ALC). Single marker, gene-based, and pathway analyses were conducted. A significant association was detected for the ADH1B locus in a gene-based approach (puncorrected = 1.2 × 10(-6); pcorrected = 0.020). This was driven by the AD subsample...

BACKGROUND: Torque Teno virus (TTV) plasma DNA load directly correlate with the level of immunosuppresion in different clinical settings. It is uncertain whether this may be the case in allogeneic hematopoietic stem cell transplant recipients (allo-HSCT). OBJECTIVES: We characterized the dynamics of TTV DNAemia in patients undergoing T-cell replete allo-SCT. STUDY DESIGN: Retrospective single-center observational study including 72 allo-HSCT patients...

Adult Leydig cells (ALCs) are the steroidogenic cells in the testes that produce testosterone. ALCs develop postnatally from a pool of stem cells, referred to as stem Leydig cells (SLCs). SLCs are spindle-shaped cells that lack steroidogenic cell markers, including luteinizing hormone (LH) receptor and 3β-hydroxysteroid dehydrogenase. The commitment of SLCs into the progenitor Leydig cells (PLCs), the first stage in the lineage, requires growth factors, including Dessert Hedgehog (DHH) and platelet-derived growth factor-AA...

BACKGROUND: Pretreatment neutrophil-to-lymphocyte ratio (NLR) and absolute lymphocyte count (ALC) recovery have been shown to be associated with prognosis in several types of cancer in adults. However, evidence in pediatric cancer is scarce. The aim of our study was to evaluate whether pretreatment NLR and lymphocyte recovery are prognostic factors in pediatric sarcomas. MATERIALS AND METHODS: Study participants were identified from a retrospective cohort of 100 children with osteosarcoma (n=55), rhabdomyosarcoma (n=22), and Ewing sarcoma (n=23)...

Several reports have shown that patients with rheumatoid arthritis (RA) are at increased risk of developing lymphoproliferative disorders (LPD). Methotrexate (MTX) has been recognized as a major cause of LPD. Sometimes spontaneous regression (SR) occurs after withdrawal of MTX. Recent studies suggest that the early recovery of the absolute lymphocyte count (ALC) after withdrawal of MTX is associated with the spontaneous regression of MTX-LPD. We retrospectively analyzed 26 patients with MTX-LPD to identify predictive factors for spontaneous regression...

Alterations in body composition (BC) as loss of fat and muscle mass (sarcopenia) are associated with poor outcome in alcoholic liver cirrhosis (ALC). Prevalence of sarcopenia depends upon the method of assessment. Computed Tomography (CT) is a gold standard tool for assessing BC AIM: To characterize BC and define sarcopenia in ALC patients using CT METHODS: Single slice CT images at L3 vertebrae of healthy controls (HC) - organ transplant donors and ALC patients were analysed to give cross-sectional area of five skeletal muscles normalized for height -skeletal muscle index (SMI; cm(2) /m(2) ), area of subcutaneous (SAT;cm(2) ) and visceral adipose tissue (VAT;cm(2) )...

BACKGROUND: Currently, most patients undergoing laparoscopic cholecystectomy (LC) in Switzerland are inpatients for 2-3 days. Due to a lack of available hospital beds, we asked whether day-case surgery would be an option for patients in central Switzerland. The questions of acceptability of outpatient LC and factors contributing to the acceptability thus arose. METHODS: Hundred patients suffering from symptomatic cholecystolithiasis, capable of communicating in German, and between 18 and 65 years old, were included...

Progressive anthropogenic disturbance can alter ecosystem organization potentially causing shifts from one stable state to another. This potential for ecosystem shifts must be considered when establishing targets and objectives for conservation. We ask whether a predator-prey system response to incremental anthropogenic disturbance might shift along a disturbance gradient and, if it does, whether any disturbance thresholds are evident for this system. Development of linear corridors in forested areas increases wolf predation effectiveness, while high density of development provides a safe-haven for their prey...

Decreased absolute lymphocyte counts (ALCs) following frontline therapy for chronic lymphocytic leukemia may be associated with disease control, even in patients without evidence of minimal residual disease. We studied the prognostic significance of ALCs during the first year following treatment with fludarabine, cyclophosphamide, and rituximab (FCR). We evaluated 99 patients who achieved a partial response without lymphocytosis (<4.0 × 10(3) cells/μL) or better after FCR. Absolute lymphocyte counts were recorded at 3-, 6-, 9-, and 12-month posttreatment and correlated with overall survival (OS) and event-free survival (EFS)...

BACKGROUND: Substance abuse in nonpregnant adults has been associated with increased intake in calories and decreased intake of nutrient-dense foods; however, studies examining dietary intake in opioid-using and alcohol-using pregnant women are lacking. OBJECTIVE: The objective of this study was to evaluate dietary intake in opioid-using pregnant women with or without concurrent light-to-moderate alcohol use as compared to abstaining controls. METHODS: This prospective birth cohort included 102 pregnant women classified into four study groups: controls (n = 27), medication-assisted treatment (MAT; n = 26), alcohol (ALC; n = 22), and concurrent use of both substances (MAT + ALC; n = 27)...

The purpose of this study is to develop a method for quantifying the fluidity of flowable resin composites using determinations of yield stress. Five commercially available composites (AliteFlo LV, Flow-it ALC, Venus flow, Tetric N-flow, Revolution Formula2) were investigated. Yield stress values were obtained by plotting shear stresses for a range of shear rates, followed by fitting of Casson fluid models to flow curve data and extrapolation to the stress axis. To confirm that yield stress reflected fluidity, apparent viscosity at the lower shear rate (0...

Little is known about the impact of multiple myeloma (MM) treatment on uninvolved immunoglobulins (Ig). We identified 448 patients who received high-dose dexamethasone (HD-DEX), lenalidomide and dexamethasone (RD), bortezomib and dexamethasone (VD), bortezomib, cyclophosphamide and dexamethasone (VCD) or bortezomib, lenalidomide and dexamethasone (VRD) for newly diagnosed MM at our institution between 2000 and 2013, and who had available data on absolute lymphocyte count (ALC) and quantitative uninvolved Ig at baseline and at the end of four cycles of therapy...

BACKGROUND: Human food subsidies can provide predictable food sources in large quantities for wildlife species worldwide. In the boreal forest of Fennoscandia, gut piles from moose (Alces alces) harvest provide a potentially important food source for a range of opportunistically scavenging predators. Increased populations of predators can negatively affect threatened or important game species. As a response to this, restrictions on field dressing of moose are under consideration in parts of Norway...

BACKGROUND: β-lactoglobulin hydrolysates (BLGH) have shown antioxidant, antihypertensive, antimicrobial, and opioid activity. In the current study, an innovative combination of high hydrostatic pressure and enzymatic hydrolysis (HHP-EH) was used to increase the yield of short bioactive peptides, and evaluate the anti-inflammatory and antioxidant properties of the BLGH produced by the HHP-EH process. METHOD: BLG was enzymatically hydrolyzed by different proteases at an enzyme-to-substrate ratio of 1:100 under HHP (100 MPa) and compared with hydrolysates obtained under atmospheric pressure (AP-EH at 0...

In polyploid species, altering a trait by random mutagenesis is highly inefficient due to gene redundancy. We have stably transformed tetraploid oilseed rape (Brassica napus) with a CRISPR-Cas9 construct targeting two ALCATRAZ (ALC) homoeologs. ALC is involved in valve margin development and, thus, contributes to seed shattering from mature fruits. Knocking out ALC would increase shatter resistance to avoid seed loss during mechanical harvest. We obtained a transgenic T1 plant with four alc mutant alleles by the use of a single target sequence...

It is well known that acetyl-l-carnitine (ALC) has various neuroprotective effects against neurodegenerative diseases. In addition, it has been reported that ALC facilitates myelination of regenerated axons after peripheral nerve injuries. We previously reported that spontaneous regeneration of the lateral olfactory tract (LOT), the main fiber tract of the central olfactory system, consistently occurred in newborn rats and a majority of these regenerated fibers were unmyelinated in neonatally LOT-transected young adult rats...

Several studies reported that stress can enhance the consumption of alcohol in humans and animals. However, the combinatorial effect of stress and alcohol on cognitive function and neurochemical alterations is quite understudied. In the present study, we have elucidated the involvement of oxidative stress-PARP cascade in alcohol and restraint stress (RS)-exposed animals using a PARP inhibitor, 1,5-isoquinolinediol (3mg/kg for 14days). Male Swiss albino mice were given alcohol (ALC) or RS (2h per day) or both in ALC+RS group for 28days...
