Vivek Labhishetty, William R Bobier
Children with a progressing myopia exhibit an abnormal pattern of high accommodative lags coupled with high accommodative convergence (AC/A) and high accommodative adaptation. This is not predicted by the current models of accommodation and vergence. Reduced accommodative plant gain and reduced sensitivity to blur have been suggested as potential causes for this abnormal behavior. These etiologies were tested by altering parameters (sensory, controller and plant gains) in the Simulink model of accommodation...

BACKGROUND AND AIMS: Endoscopic enteral stenting (ES) in malignant gastric outlet obstruction (GOO) is limited by high rates of stent obstruction. EUS-guided gastroenterostomy (EUS-GE) is a novel procedure that potentially offers sustained patency without tumor ingrowth/overgrowth. The aim of this study is to compare EUS-GE with ES in terms of (1) symptom recurrence and need for re-intervention, (2) technical success (proper stent positioning as determined via endoscopy and fluoroscopy), (3) clinical success (ability to tolerate oral intake without vomiting), and (4) procedure-related adverse events (AEs)...

OBJECTIVE: Acid digestion of animal tissues yields two fractions of glycogen, acid soluble (ASG) and insoluble (AIG). The current study was performed to improve the assay method for glycogen fractions in rat liver in different physiological states. MATERIALS AND METHODS: All steps of the assay were manipulated and optimized to measure the content of ASG and AIG in fed and starved rat liver. RESULTS: In postmortem liver tissue, total glycogen was decreased slowly at 4°C and rapidly at 25°C but was well stabilized at -20°C and -70°C...

Tetramethylpyrazine (TMP) and astragaloside IV (AGS-IV) are herbal ingredients that have been demonstrated in animal models to limit infarct size and protect cardiomyocytes in the acute phase of myocardial infarction (MI), yet their long-term cardio-protective effects have not been evaluated. In the present study, TMP and/or ASG-IV were administrated to rats for 14 days after MI. Echocardiography revealed that the left ventricular (LV) dimensions and cardiac function was preserved in the MI rats with TMP and ASG-IV treatment, compared to untreated MI rats...

The American Society for Gastrointestinal Endoscopy (ASGE)/American College of Gastroenterology Task Force (ACGTF) on Quality in Endoscopy released updated quality benchmarks for colonoscopy in 2015. Our initial study concluded that surgery residents could perform safe and competent screening colonoscopy within a structured endoscopy curriculum. In this follow-up study, we sought to determine whether surgery residents could achieve the increased adenoma detection rate (ADR) benchmarks endorsed by the ASGE/ACGTF...

This study was aimed at evaluation of the contribution of acid-soluble glycoproteins (ASG)/mucins and extracellular vesicles (EVs), yet unexplored components of human seminal plasma (hSP) to the complexity of its glycome. Gaining insight into the native presentation and distribution of glycans across hSP could help establish molecular environments supporting specific biological activities based on unique ligand capacities. Soluble and particulate fractions of hSP from healthy subjects were analyzed by gel filtration, electrophoresis, ion-exchange chromatography and a solid phase assay with immobilized charge-resolved glycospecies to test their reactivity with plant lectins, carbohydrate-binding antibodies and selected human lectins...

Juvenile hormone (JH) regulates the insect growth and development. JH appears in the hemolymph bound by a specific glycoprotein, juvenile hormone-binding protein (JHBP), which serves as a carrier to release the hormone to target tissues and cells. However, JHBP family candidates, expression patterns, and functional implications are still unclear. In this study, we identified 41 genes-containing conserved JHBP domains distributed across eight chromosomes of the silkworm Bombyx mori. A phylogenetic tree showed that the silkworm JHBP (BmJHBP) genes could be classified into two major branches and four subfamilies...

BACKGROUND AND AIM: Total aphagia from complete esophageal obstruction (CEO) can be seen in patients with head-neck or thoracic malignancies undergoing chemoradiation or surgery. Combined antegrade and retrograde endoscopy (via G-tube tract) is often performed for esophageal reconstruction but is limited by the length of the obstructed esophagus. We describe per-oral endoscopic tunneling for restoration of the esophagus (POETRE), for patients with longer segments of esophageal obstruction...

Here we report the development of an antibody-drug conjugate, ASG-5ME, which targets the solute carrier receptor SLC44A4. SLC44A4 is a member of a family of putative choline transporters which we show to be markedly upregulated in a variety of epithelial tumors, most notably prostate and pancreatic cancer. SLC44A4 is normally expressed on the apical surface of secretory epithelial cells but in cancer we show expression is not restricted to the luminal surface in advanced and undifferentiated tumors. ASG-5ME consists of a human IgG2 anti-SLC44A4 antibody conjugated through a cleavable linker to the microtubule-disrupting agent, monomethylauristatin E...

Xiou Cao, Alejandro Aballay
The innate immune system is the front line of host defense against microbial infections, but its rapid and uncontrolled activation elicits microbicidal mechanisms that have deleterious effects [1, 2]. Increasing evidence indicates that the metazoan nervous system, which responds to stimuli originating from both the internal and the external environment, functions as a modulatory apparatus that controls not only microbial killing pathways but also cellular homeostatic mechanisms [3-5]. Here we report that dopamine signaling controls innate immune responses through a D1-like dopamine receptor, DOP-4, in Caenorhabditis elegans...

The silk gland of silkworm is the organ of silk protein synthesis and secretion. According to the morphological and functional differences, silk gland can be divided into anterior silk gland (ASG), middle silk gland (MSG) and posterior silk gland (PSG). ASG is the place for silk proteins conformation changes although it cannot synthetize silk proteins. ASG has narrow luminal structures and rigid wall which consists of chitin and cuticle proteins so that it can provide the shearing force which plays an important role in the silk protein conformation changes...
