Contaminant profiles in sediment cores represent valuable natural archives of environmental contamination, by which contaminant sources and historical changes in contaminant input and cycling may be recognized. In the present study, we discuss the sedimentary profiles and historical trends of organic contaminants - polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) - in three fjords of the Svalbard archipelago differing in environmental conditions and anthropogenic impact. The obtained results revealed no significant differences between the fjords Hornsund and Kongsfjorden, in the average levels of the analyzed contaminants...

Snehapana i.e. internal administration of fat is the essential step prior to Vamana and Virechana (therapeutic vomiting and purgation). But it was found that 10-15% patients has got reluctance towards Snehapana hence may deprive the benefits of Shodhana. These inconveniences made us think about effective alternative to counter drawbacks of Snehapana. On the basis of literary review and pilot study, it was confirmed that, Anuvasana Basti can be administered as an alternative for Snehapana. To evaluate samyak snigdha lakshana i...

BACKGROUND: Ulcerative colitis patients have been historically treated with standard single, two and three stage operative approaches. We perform a variant two-stage procedure beginning with total abdominal colectomy and end ileostomy followed by completion proctectomy and ileal pouch-anal anastomosis without a diverting loop ileostomy. The present study evaluates the effectiveness of this innovative alternative. STUDY DESIGN: Patients with ulcerative colitis admitted to UNC Hospital between 2003 and 2010 for IPAA were eligible for inclusion...

BACKGROUND: The antenatal diagnosis of a combined esophageal atresia without tracheoesophageal fistula and duodenal atresia with or without gastric perforation is a rare occurrence. These diagnoses are difficult and can be suspected on ultrasound by nonspecific findings including a small stomach and polyhydramnios. Fetal magnetic resonance imaging adds significant anatomical detail and can aid in the diagnosis of these complicated cases. Upon an extensive literature review, there are no reports documenting these combined findings in a twin pregnancy...

INTRODUCTION: One anastomosis gastric bypass (OAGB) demonstrated results similar to traditional Roux-en-Y procedures [1-3], in terms of weight loss and resolution of obesity-related comorbidities. The main controversy regarding OAGB is the concern for an association between biliary alkaline gastritis and esophageal or gastric cancer raised by some studies [4]. METHODS: We present the case of a 51-year-old woman with a BMI of 41 kg/m2 who underwent a laparoscopic OAGB in 2014...

The transsacral approach is not routinely used for treating rectal tumors. We report the case of a 65-year-old man with a large adenoma at the posterior wall of the mid-rectum who was treated via the transsacral approach. The same lesion had been treated using transsacral endoscopic microsurgery 8 years previously. Moreover, 11 years previously he had undergone a laparotomy for bladder cancer, and an Indiana pouch had been constructed. Abdominal computed tomography showed that the pouch was adjacent to the rectum...

BACKGROUND: Our previous study showed that nephrolithiasis is a common complication in ulcerative colitis patients after ileal pouch anal anastomosis (IPAA). However, the pathogenesis of nephrolithiasis in IPAA patients has not been studied. The aim of this study was to compare urine and serum metabolic compositions in IPAA patients with nephrolithiasis and controls with IPAA and no nephrolithiasis. METHODS: Using cross-sectional study design, serum and 24-hour urine metabolic compositions were compared between IPAA patients with nephrolithiasis (the study group) and those without (the control group)...

Angiogenesis is both a physiological and a pathological process of great complexity, which is difficult to measure objectively and automatically. The hamster cheek pouch (HCP) prepared for intravital-microscopy (IVM) has been used to characterize microvascular functions in many studies and was chosen to investigate microvascular characteristics observed in normal non-infected hamsters as compared to those HCPs parasitized by Trypanosoma cruzi. Images of HCPs captured at IVM were subjected to computer based measurements of angiogenesis and histamine-induced macromolecular (FITC-dextran) leakage with an image segmentation approach that has the capacity to discriminate between fluorescence emitted by macromolecular tracers inside the vasculature and in the extravascular space...

Microfluidic cassettes ("chips") for processing and analysis of clinical specimens and other sample types facilitate point-of-care (POC) immunoassays and nucleic acid based amplification tests. These single-use test chips can be self-contained and made amenable to autonomous operation-reducing or eliminating supporting instrumentation-by incorporating laminated, pliable "pouch" and membrane structures for fluid storage, pumping, mixing, and flow control. Materials and methods for integrating flexible pouch compartments and diaphragm valves into hard plastic (e...

BACKGROUND: Clostridium difficile infection (CDI) in patients with the ileal pouch after proctocolectomy has been increasingly recognized. We sought to evaluate the frequency and risk factors of CDI in patients with the primary or secondary discharge diagnosis of pouchitis in the United States. METHODS: We reviewed the National Inpatient Sample of the Healthcare Cost and Utilization Project and identified patients admitted for pouchitis with underlying inflammatory bowel disease (IBD) or familial adenomatous polyposis (FAP), between 2010 and 2012...

OBJECTIVE: Following thermal burn injury, plasma fibronectin degrades within the interstitium; one possible product is epiviosamine-1 (EVA-1, PSHISKYILRWRPK) found within the first type III repeat of plasma fibronectin (FNIII1 ). EVA-1 ameliorates thermal burn injury progression, and binds to and enhances platelet-derived growth factor-BB (PDGF-BB) in promoting cell metabolism, growth and survival; shorter related peptides lose these abilities. Here we study the effect of EVA-1 and shorter peptides for their vasoactivity under quiescent and stress conditions...

Dietary fatty acid patterns have been linked to the prevalence of certain cancers, however in oral carcinoma is limited. Thus, we investigated the chemopreventive effects of various dietary n-6 and n-3 fatty acids in a 9,10-dimethyl-1,2-benz[a]-anthracene (DMBA)- and betel quid extract (BQE) -induced hamster oral cancer model. Thirty 6-week-old adult male hamsters were housed and divided into normal, low, and high dietary n-6 and n-3 fatty acid groups under DMBA + BQE treatment for 16 weeks. The right buccal pouch of all hamsters were evaluated by tumor number, volume, burden and selected inflammatory parameters...

Chemokines promote leukocyte recruitment during inflammation. The oxidative burst is an important effector mechanism, this leads to the generation of reactive nitrogen species (RNS), including peroxynitrite (ONOO). The current study was performed to determine the potential for nitration to alter the chemical and biological properties of the prototypical CC chemokine, CCL2. Immunofluorescence was performed to assess the presence of RNS in kidney biopsies. Co-localisation was observed between RNS-modified tyrosine residues and the chemokine CCL2 in diseased kidneys...

Mei Diao, Long Li, Kao-Ping Guan, Zhen Zhang, Wei Cheng
BACKGROUND: The repair of anorectal malformation (ARM) with low recto-bulbar fistula (bowel-to-skin distance: 1-1.5 cm) is contraindicated for laparoscopy due to the difficulty in exposing the fistulae. Posterior or anterior sagittal anorectoplasty is thus conventionally carried out for low recto-bulbar fistula repair. However, these procedures carry the potential risk of wound infection/dehiscence and incontinence. We have developed a single-incision laparoscopic-assisted perineal anorectoplasty (SILPARP) technique...

Robust lateralization in forelimb use has recently been found in bipedal, but not quadrupedal, marsupial mammals. The link between bipedality and handedness, occurring in both marsupials and primates, remains to be investigated. To shed light on the developmental origins of marsupial manual lateralization, infants of macropod marsupials were examined before and shortly after the acquisition of habitual bipedal posture and locomotion. Forelimb preferences were assessed in natural, not artificially evoked, behaviors of infant red-necked wallaby in the wild and infant eastern gray kangaroo in free-ranging captivity...
