Yoshikazu Ohno, Akira Iguchi, Chuya Shinzato, Mayuri Inoue, Atsushi Suzuki, Kazuhiko Sakai, Takashi Nakamura
Corals build their skeletons using extracellular calcifying fluid located in the tissue-skeleton interface. However, the mechanism by which corals control the transport of calcium and other ions from seawater and the mechanism of constant alkalization of calcifying fluid are largely unknown. To address these questions, we performed direct pH imaging at calcification sites (subcalicoblastic medium, SCM) to visualize active pH upregulation in live aposymbiotic primary coral polyps treated with HCl-acidified seawater...

BACKGROUND: Whilst polyp size has been traditionally used as a predictor of the complexity of endoscopic resection, the influence of other factors is increasingly recognised. The SMSA grading system takes into account polyp Site, Morphology, Size and Access, with higher scores correlating with increased technical difficulty. AIMS: To evaluate whether the SMSA grading tool correlates with endoscopic and clinical outcomes. METHODS: This retrospective study was conducted at two high volume centres in the United Kingdom and Italy...

(no author information available yet)
Decamethylcyclopentasiloxane (D5; CAS No. 541-02-6) is a precursor in the production of siloxane polymers for industry and medicine and is a carrier ingredient in many toiletries and cosmetics. D5 has a relatively low order of toxicity following acute administration via the oral, dermal, and inhalation routes of exposure. It is not considered to be a dermal or eye irritant or a dermal sensitizer. There is no appreciable dermal absorption of D5 based on results from in vivo and in vitro studies. It has not been shown to be genotoxic/mutagenic when tested in a number of short-term in vitro and in vivo assays and did not cause reproductive or developmental toxicity in rats...

Near-infrared fluorescent cholangiography (NIRFC) is an emerging technique for easy intraoperative recognition of biliary anatomy. We present a case of cystic duct variation detected by NIRFC which had a potential risk for biliary injury if not detected. A 32-year-old female was admitted to the Seoul St. Mary's Hospital for surgery for an incidental gallbladder polyp. We performed laparoscopic cholecystectomy with NIRFC. In fluorescence mode, a long cystic duct and an accessory short hepatic duct joining to the cystic duct were found and the operation was completed safely...

We examine the expression of tight junction and adherence junction proteins in the colorectal mucosa of miniature dachshunds (MDs) with inflammatory colorectal polyps (ICRPs). Colorectal mucosa samples were endoscopically obtained from 8 MDs with ICRPs and 8 control dogs for immunoblotting. Paraffin-embedded tissues of surgically resected inflamed lesions from another 5 MDs with ICRPs and full-thickness colorectal specimens from 5 healthy beagles were obtained for immunohistochemistry. The expression patterns of claudin-1, -2, -3, -4, -5, -7 and -8, E-cadherin and β-catenin were analyzed in the non-inflamed mucosa and inflamed mucosa of ICRPs and colorectal mucosa of control dogs by immunoblotting...

BACKGROUND: Sleeve gastrectomy (SG) is quickly becoming the preferred procedure for bariatric surgery. According to the American Society for Metabolic and Bariatric Surgery guidelines, routine preoperative upper gastrointestinal endoscopies are not recommended universally for bariatric surgery. Some studies have shown that the histologic examination of SG specimens is insignificant and not a cost-effective practice. However, some speculate SG examination may unveil pertinent findings and prevent further progression of precursor lesions...

Inflammatory colorectal polyps (ICRPs) are characterized by the formation of multiple or solitary polyps with marked neutrophil infiltration in the colorectal area, and are speculated to be a novel form of breed-specific canine idiopathic inflammatory bowel disease (IBD). In human IBD, toll-like receptor (TLR) 2 and TLR4 have been reported to be involved in the pathogenesis of the disease. The aim of this study was to evaluate the expression of TLR2 and TLR4 mRNA in the colorectal mucosa of dogs with ICRPs by in-situ hybridization using an RNAscope assay...

Holly J Holman, Katherine Gailbreath
An 8-yr-old nulliparous, female rock hyrax ( Procavia capensis ) had intermittent mucoid to bloody discharge late winter-early spring for two consecutive years. Fragments of necrotic tissue, suspected to be vaginal or rectal in origin, were passed on two occasions. Physical examination, radiographs, and ultrasound did not identify the source of the tissue. Exploratory laparotomy and ovariohysterectomy were performed. On histopathology, a diagnosis of adenomyosis with a uterine polyp was made. Postsurgical complications included incisional infection and renal compromise that were medically managed and resolved...

BACKGROUND: The overall incidence of colorectal cancer (CRC) in the United States has steadily decreased. However, the incidence of right-sided CRC remains unchanged for the past two decades. The serrated neoplastic pathway (sessile serrated adenoma/polyp, SSA/P) has been considered an important pathway of colorectal carcinogenesis, especially in the right-sided CRC. The aim of this study was to compare CRC anatomic distribution patterns in a 9-year interval in the general population before and after SSA/P was recognized and treated as a CRC precursor...

REVIEW
Shu-Yi Yang, Teng-Kuei Huang, Hui-Fen Kuo, Tzyy-Jen Chiou
Vacuoles play a fundamental role in storage and remobilization of various nutrients, including phosphorus (P), an essential element for cell growth and development. Cells acquire P primarily in the form of inorganic orthophosphate (Pi). However, the form of P stored in vacuoles varies by organism and tissue. Algae and yeast store polyphosphates (polyPs), whereas plants store Pi and inositol phosphates (InsPs) in vegetative tissues and seeds, respectively. In this review, we summarize how vacuolar P molecules are stored and reallocated and how these processes are regulated and co-ordinated...

The real cause of intussusception is not fully understood and a variety of conditions have been associated with it (Meckel diverticulum, polyps, duplication cysts, parasites, Henoch-Schönlein purpura, cystic fibrosis, hemolytic-uremic syndrome and infectious gastroenteritis). Furthermore few European countries, following WHO recommendation to monitor baseline incidence of intussusception before implementation of immunization program for rotavirus, used intussusception rate as a baseline value to compare the same figures in the period before and after introduction of vaccination...

Babi Ramesh Reddy Nallamilli, Madhuri Hegde
Hereditary forms of colorectal cancer (CRC) account for up to 5% of total cases. Familial adenomatous polyposis (FAP) is an autosomal dominant condition affecting nearly 1 in 5000 people and accounts for only about 1% of all CRCs. It is characterized by the progressive development of hundreds to thousands of adenomatous colon polyps. The gene associated with FAP (APC) contains 15 coding exons. The mutation spectrum of the APC gene is broad in that 87% of causative mutations are point mutations (including other sequence variants) and around 10% to 15% are intragenic deletions and duplications...

Resveratrol (RSV) has been shown to effectively suppress chronic rhinosinusitis with nasal polyps in a mouse model; however, when locally administered to the sinonasal cavity, bolus RSV is limited by low drug bioavailability owing to its low aqueous solubility and relatively rapid clearance from the administration site. To address this limitation, we propose mucoadhesive nanostructured microparticles (PLGA/PEG NM) as a potential carrier for the sinonasal delivery of RSV. In this study, PLGA/PEG NM released RSV in a sustained manner...
