BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery is a safe and effective procedure for patients with severe obesity. One potential complication of LRYGB is the development of marginal ulcers (MUs). Nonsteroidal anti-inflammatory drugs (NSAIDs) are known to significantly increase the likelihood of developing marginal ulcers after surgery. However, the risk associated with low-dose aspirin consumption is not well defined. We examined the impact of daily low-dose aspirin (81 mg) on the development of marginal ulcers following LRYGB...

Distinct populations of D1- and D2-dopamine receptor expressing medium spiny neurons (D1-/D2-MSNs) comprise the nucleus accumbens, and activity in D1-MSNs promotes, while activity in D2-MSNs inhibits motivated behaviors. We used chemogenetics to extend D1-/D2-MSN cell specific regulation to cue-reinstated cocaine seeking in a mouse model of self-administration and relapse, and found that either increasing activity in D1-MSNs or decreasing activity in D2-MSNs augmented cue-induced reinstatement. Both D1- and D2-MSNs provide substantial GABAergic innervation to the ventral pallidum, and chemogenetic inhibition of ventral pallidal neurons blocked the augmented reinstatement elicited by chemogenetic regulation of either D1- or D2-MSNs...

Porcinereproductiveandrespiratorysyndromevirus (PRRSV) causes significant economic losses to the pork industry worldwide. Previously, we demonstrated that heme oxygenase-1 (HO-1) interferes with PRRSV replication. To elucidate the mechanisms involved, here we assess whether the HO-1 downstream metabolites biliverdin (BV) and/or iron mediate the HO-1 antiviral effect. We demonstrate a BV concentration-dependent suppression of PRRSV replication and show that virions are not directly inactivated by BV. Additionally, BV or N-acetyl cysteine (NAC) significantly reduced reactive oxygen species (ROS) in PRRSV-infected MARC-145 cells; however, because NAC did not reduce viral load, the BV antiviral effect is independent of decreased ROS levels...

PURPOSE OF REVIEW: The purpose is to review recent advances concerning the role of nuclear medicine in endocrine oncology. RECENT FINDINGS: For I therapy of thyroid cancer a thyrotropin (TSH) more than 30 mU/l has for many years been deemed a condition sine qua non. However, new data show that patients with lower TSH levels at the time of ablation have the same rate of successful ablation as those with TSH more than 30 mU/l.I-124 combined integrated positron emission tomography and computed X-ray tomography was shown to be highly accurate in predicting findings on posttherapy radioiodine scanning and was shown to have a high prognostic power...

Almost all the deformable mirror (DM) based adaptive optics systems (AOSs) used on large aperture telescopes work at the infrared waveband due to the limitation of the number of actuators. To extend the imaging waveband to the visible, we propose a DM and Liquid crystal wavefront corrector (DM/LCWFC) combination AOS. The LCWFC is used to correct the high frequency aberration corresponding to the visible waveband and the aberrations of the infrared are corrected by the DM. The calculated results show that, to a 10 m telescope, DM/LCWFC AOS which contains a 1538 actuators DM and a 404 × 404 pixels LCWFC is equivalent to a DM based AOS with 4057 actuators...

Glutathione-S-transferases mu 2 (GSTM2), a kind of important Phase II antioxidant enzyme of eukaryotes, is degraded by nonsense mediated mRNA decay due to a C27T substitution in the fifth exon of pigs. As a reproductive performance-related gene, GSTM2 is involved in embryo implantation, whereas, functional deficiency of GSTM2 induces pre- or post-natal death in piglets potentially. To have some insight into the role of GSTM2 in embryo development, high throughput RNA sequencing is performed using the swine testis cells (ST) with the deletion of GSTM2...

The purpose of this study is to test the hypothesis that the mammalian target of rapamycin (mTOR) signaling pathway might mediate neuroprotection in a mouse model of septic encephalopathy and also to identify the role of autophagy. Mice were subjected to cecal ligation and puncture (CLP) or a sham operation, and all 50 mice were randomly assigned to five groups: sham, CLP+ saline, CLP+ rapamycin (1, 5, 10 mg/kg) groups. Two weeks after the operation, Morris water maze was conducted for behavioral test; Nissl staining was used for observing glia infiltration; immunohistochemical staining and biochemical measures in hippocampi were performed to detect mTOR targets and autophagy indicators...

Accumulating evidence suggests that aberrantly expressed microRNAs (miRNAs) contribute to the initiation and progression of human cancers. However, the underlying function of miR-193b in colorectal cancer (CRC) remains largely unexplored. Herein, we demonstrate that miR-193b is significantly down-regulated in CRC tissues compared with their normal counterparts. Kaplan-Meier analysis revealed that decreased miR-193b expression was closely associated with the shorter overall survival of patients with CRC. Through gain-and loss-of-function studies, we showed that miR-193b significantly suppressed CRC cell proliferation and invasion...

The exact roles of copy number alteration (CNA) in initiation, progression and immunotherapy of breast cancer and the genomic alterations behind progression from ductal carcinoma in situ (DCIS) to invasive carcinoma remain unknown. Quantitative multi-gene fluorescence in situ hybridization (QM-FISH) opens a possibility of large scale genomic analysis of specific deletions and amplifications with high-resolution at one cell level. We detected CNAs of 30 genes using QM-FISH and analyzed their association with clinicopathological parameters and patients' outcomes in 66 breast cancers with synchronous invasive carcinoma and DCIS...

BACKGROUND: mu-opioid receptor (OPRM1) and catechol-O-methyltransferase (COMT) contribute to the neurotransmission pathway of pain. COMT affects mu receptor expression and density in the brain. The aim of this study was to explore the OPRM1 and COMT interaction effects on postoperative pain and opioid consumption. METHODS: This cross-sectional exploratory study used genotype and clinical data from 153 postoperative patients. Using multiple regression analyses, four single-nucleotide polymorphisms of COMT (rs6269, rs4633, rs4818, and rs4680), their haplotypes, and diplotypes were considered for their interactions with A118G of OPRM1 regarding postoperative pain and opioid consumption...

Pain is a significant clinical problem and there is a need for more effective treatments with reduced adverse effects that currently limit the use of mu opioid receptor agonists. Synthetic kappa opioid receptor agonists have no abuse liability and well-documented antinociceptive effects; however, adverse effects (diuresis, dysphoria) preclude their use in the clinic. Combining kappa opioids with non-opioid drugs (cannabinoid receptor agonists) allows for smaller doses of each drug to produce antinociception...
