BACKGROUND: An oral sugar test (OST) using Karo(®) Light Corn Syrup has been developed in the USA as a field test for the assessment of insulin dysregulation in horses but the syrup is not available in Scandinavian grocery stores. The aim of the study was to compare the results of a modified OST between horses with equine metabolic syndrome (EMS) and healthy horses using a Scandinavian commercially available glucose syrup (Dansukker glykossirap). In addition, the effect of breed and the repeatability of the test were evaluated...

OBJECTIVE: To determine if vanishing testis could result from a fault in embryological development as a result of an arrest in endothelial cell migration rather than secondary to just a random physical torsion/twist. .A testicular nubbin or vanishing testis is considered to be secondary to a neonatal torsion and is usually associated with a hemosiderin deposit. METHODS: Cases of vanishing testis excision were compared with age-matched controls from cadaveric testes without known genitourinary pathology...

The endoplasmic reticulum (ER) has the ability to signal organelle dysfunction via a complex signaling network known as the unfolded protein response (UPR). In this work, hamster fibroblast cells exhibiting moderate levels of ER stress were compared to those exhibiting severe ER stress. Inhibition of N-linked glycosylation was accomplished via a temperature-sensitive mutation in the Dad1 subunit of the oligosaccharyltransferase (OST) complex or by direct inhibition with tunicamycin (Tm). Temperature shift (TS) treatment generated weak activation of ER stress signaling when compared to doses of Tm that are typically used in ER stress studies (500-1000 nM)...

Tinnitus is the perception of a sound in the absence of a corresponding external sound source. Research has suggested that functional abnormalities in tinnitus patients involve auditory as well as non-auditory brain areas. Transcranial electrical stimulation (tES), such as transcranial direct current stimulation (tDCS) to the dorsolateral prefrontal cortex and transcranial random noise stimulation (tRNS) to the auditory cortex, has demonstrated modulation of brain activity to transiently suppress tinnitus symptoms...

In recent years, neural stem cell (NSC) transplantation has been widely explored as a treatment for neurodegenerative diseases. NSCs are special cells that have some capacity for self-renewal and the potential to differentiate into multiple cell types. However, the inflammatory environment of diseased tissue is not conducive to the survival of transplanted cells. Osthole (Ost) is a principal bioactive component of Fructus Cnidii, Radix Angelicae Pubescentis and other traditional Chinese medicines. Ost has a wide range of pharmacological activities, such as anti-inflammation, immunomodulation, and neuroprotection...

BACKGROUND: Drug consumption rooms (DCRs) have been implemented worldwide as a harm-reducing strategy. In 2012, Denmark passed legislation allowing establishment of DCRs. The aim of this study was to identify characteristics and gain knowledge of the way service users use the DCRs including bridge building to specialized health care. Associations between nationality, opioid substitution treatment (OST), drug intake method, and response to staff advice on harm-reducing education was investigated, as well as service user's reasons for using the DCRs, and their perceptions of safety and trust in the DCRs...

The presence of aromatic amines in the environment has been in the focus of research, as many of these compounds are known or suspected mutagens and carcinogens. To facilitate the detection of aromatic amines in complex environmental samples by LC-high resolution mass spectrometry, an on-line-post-column and a pre-column derivatization method to label (in an ideal case) all aromatic amines was evaluated by applying different derivatization reagents. 4-Fluoro-7-nitro-2,1,3-benzoxadiazole (NBD-F) was found to be the most promising labeling reagent due to its high reactivity with both primary and secondary amines and its low signal in positive mode electrospray ionization (ESI+)...

Asparagine (N)-linked glycosylation is a protein modification critical for glycoprotein folding, stability, and cellular localization. To identify small molecules that inhibit new targets in this biosynthetic pathway, we initiated a cell-based high-throughput screen and lead-compound-optimization campaign that delivered a cell-permeable inhibitor, NGI-1. NGI-1 targets oligosaccharyltransferase (OST), a hetero-oligomeric enzyme that exists in multiple isoforms and transfers oligosaccharides to recipient proteins...

BACKGROUND AND AIMS: Opioid substitution therapy (OST) is an effective treatment for opioid dependence that is provided in many correctional settings, including New South Wales (NSW), Australia. In 2011, changes to the clinical governance of the NSW prison OST program were implemented, including a more comprehensive assessment, additional specialist nurses, and centralization of program management and planning. This study aimed to document the NSW prison OST program, and assess the impact of the enhanced clinical governance arrangements on retention in treatment until release, the provision of an OST prescription to patients at release, and presentation to a community OST clinic within 48 hours of release from custody...

Age-related bone loss is associated with an increased oxidative stress which is worsened by estrogen fall during menauposis. This observation has drawn attention to autophagy, a major cellular catabolic process, able to alleviate oxidative stress in osteoblasts (OB) and osteocytes (OST), two key bone cell types. Moreover, an autophagy decline can be associated with aging, suggesting that an age-related autophagy deficiency in OB and/or OST could contribute to skeletal aging and osteoporosis onset.In the present work, autophagy activity was analyzed in OST and OB in male and female mice according to their age and hormonal status...

Obsessive-compulsive disorder (OCD) is ranked by the World Health Organization (WHO) among the 10 most debilitating disorders. The treatments which have been found effective are cognitive behavior therapy (CBT) and serotonin reuptake inhibitors (SRI). This meta-analysis includes all RCTs of CBT (25) and SRI (9) for OCD in youth using the Children's Yale-Brown Obsessive Compulsive Scale (C-YBOCS). CBT yielded significantly lower attrition (12.7%) than SRI (23.5%) and placebo (24.7%). The effect sizes for comparisons of CBT with waiting-list (1...

Salmon exposed to waterborne metals can experience olfactory impairment leading to disrupted chemosensation. In the current study, we investigated the effects of cadmium (Cd) on salmon olfactory function by modeling an exposure scenario where juvenile salmon transiently migrate through a polluted waterway. Coho were exposed to environmentally-relevant concentrations of waterborne Cd (2 and 30 μg/L) for 48 hrs and (0.3 and 2 μg/L) for 16 days, followed by a 16-day depuration associated with outmigration. Cadmium exposures inhibited behavioral responses towards L-cysteine and conspecific odorants, with effects persisting following the depuration...

BACKGROUND/PURPOSE: Premature neonates can develop intraabdominal conditions requiring emergent bowel resection and enterostomy. Parenteral nutrition (PN) is often required, but results in cholestasis. Mucous fistula refeeding allows for functional restoration of continuity. We sought to determine the effect of refeeding on nutrition intake, PN dependence, and PN associated hepatotoxicity while evaluating the safety of this practice. METHODS: A retrospective review of neonates who underwent bowel resection and small bowel enterostomy with or without mucous fistula over 2years was undertaken...

PURPOSE: Improved outcome is reported after surgery or external beam radiation therapy (EBRT) plus androgen deprivation therapy (ADT) for patients with lymph node (LN) positive (N1) prostate cancer (PC). Surgical series have shown that pathologic (p)N1 PC does not behave the same in all patients. The aim of this study was to perform a matched-case analysis to compare the outcome of pN1 and pN0 PC after high-dose EBRT plus ADT. METHODS AND MATERIALS: Radiation therapy up to 80 Gy was delivered to the prostate with a minimal dose of 45 Gy to the pelvis for pN1 patients...

In 2013 a 40 year old man came to visit in our Rheumatology Unit because of a recent bilateral shoulder and hip pain. He had been treated from 1990 to 2000 with Cyclosporin A and Sulfasalazyn because of an ulcerative colitis which was completely in remission from 2000 . Glucocorticoids at the mean daily dose of 50 mg were administered only in the first period (1990-92). X-plain rays showed a suspicious multifocal osteonecrosis of both femoral and humeral heads. Magnetic Resonance confirmed the diagnosis (stage III and IV following Ficat and Arlet's criteria)...
