It was recently shown that fasting alters the composition of microbial communities residing in the distal intestinal tract of animals representing five classes of vertebrates [i.e., fishes (tilapia), amphibians (toads), reptiles (leopard geckos), birds (quail), and mammals (mice)]. In the current study, we tested the hypothesis that the extent of tissue reorganization in the fasted distal intestine was correlated with the observed changes in enteric microbial diversity. Segments of intestine adjacent to those used for the microbiota study were examined histologically to quantify cross-sectional and mucosal surface areas as well as thicknesses of mucosa, submucosa, and tunica muscularis...

A total of 720 straight-run Heritage 56 M × fast feathering Cobb 500F broiler chickens was fed from 11 to 13 d of age to determine the impacts of dietary calcium (Ca), phytate phosphorus (PP), and phytase concentrations on inositol phosphate (IP3-6) profile in different digestive tract (GI) segments. The experiment was a 2 × 2 × 3 randomized block design with 2 Ca (0.7 and 1.0%) and 2 PP (0.23 and 0.34%) concentrations and 3 doses of Buttiauxella sp. phytase (0, 500, and 1,000 FTU/kg). The experiment was replicated in time (block) with 3 replicates per treatment (Trt) of 10 birds per block...

During the course of a QTL study involving an intercross between White Plymouth Rock chickens and Red Jungle Fowl, certain reproductive anomalies such as atresia and double ovary-oviduct became evident. Observed in reciprocal pedigreed F1 crosses were 2 full-sib pullets with dual functioning ovaries. One also had complete functioning left and right oviducts. The other had asymmetrical reproductive tracts with a typical left oviduct and a rudimentary right oviduct. In addition, there were 3 females with atresia...

There are inconsistent conclusions in the association between circulating tumor cells (CTCs) and urothelial cancer (UC). We performed a meta-analysis to assess the prognostic and diagnostic value of CTCs in UC. We search Medline, Embase and Web of science for relevant studies. The study was set up according to the inclusion/exclusion criteria. 30 published studies with a total of 2161 urothelial cancer patients were included. Meta-analysis showed that CTC-positive was significantly associated with tumor stage (≤ II vs III, IV) (OR = 4...

Circulating tumor DNA (ctDNA), extracted from plasma, is a non-invasive surrogate biomarker. However, the distribution of ctDNA in the body still remains to be elucidated. In this study, resected lung tumors, with simultaneous blood and bone marrow samples, were analyzed to elucidate the distribution of ctDNA. Rib bone marrow, pulmonary venous blood (Pul.V) and peripheral blood (Peri.B) were obtained from 30 patients. The liquid samples were divided into cell pellets and supernatant by centrifugation; a total of 212 DNA samples were subjected to massively parallel sequencing...

BACKGROUND: Schizophrenia is associated with diverse white matter (WM) brain abnormalities. In this study, we sought to examine the WM microstructural findings which underlie clinical psychopathology clusters in schizophrenia and hypothesized that these symptom clusters are associated with common and unique WM tracts. METHODS: Overall, 76 healthy controls (HC), and 148 patients with schizophrenia (SZ) were recruited and severity of symptomatology in schizophrenia was assessed using the Positive and Negative Syndrome Scale...

BACKGROUND: Air pollution is thought to raise the risk of neurological disease by promoting neuroinflammation, oxidative stress, glial activation and cerebrovascular damage. Multiple Sclerosis is a common auto-immune disorder, primarily affecting young women. We conducted, to a large prospective study of particulate matter (PM) exposure and multiple sclerosis (MS) risk in two prospective cohorts of women: the Nurses Health Study (NHS) and the Nurses Health Study II (NHS II). METHODS: Cumulative average exposure to different size fractions of PM up to the onset of MS was estimated using spatio-temporal models...

Inflammatory bowel diseases (IBD) are chronic inflammatory disorders of the gastrointestinal tract, strongly associated with an increased risk of colorectal cancer development. Parasitic infections caused by helminths have been shown to modulate the host's immune response by releasing immunomodulatory molecules and inducing regulatory T cells (Tregs). This immunosuppressive state provoked in the host has been considered as a novel and promising approach to treat IBD patients and alleviate acute intestinal inflammation...

Sociodemographic correlates of engagement in human immunodeficiency virus (HIV) care are well studied, however the association with accessing drug resistance testing (DRT) and the development of drug resistance have not been characterized. Between 1996-2014, 11 801 HIV patients accessing therapy in British Columbia were observed longitudinally. A subset of 9456 patients had testable viral load; of these 8398 were linked to census data. Sociodemographic (census tract-level) and clinical (individual-level) correlates of DRT were assessed using multivariable General Estimating Equation logistic regression adjusted odds ratios (aOR)...

The authors describe the case of a patient with the classic clinical presentation and radiographic features of a nasal dermal sinus with an associated intracranial cyst; however, histopathology revealed that the intracranial cyst was neurenteric instead of the typical epidermoid or dermoid cyst. Preoperative assessment included CT and MRI, which revealed a direct communication between the patient's nasal polypoid lesion and the anterior skull base via the foramen cecum. At the hands of a multidisciplinary plastic surgery and neurosurgery team, the patient underwent concurrent gross-total resection of the nasal polypoid lesion, the intracranial intradural cystic lesion, and their interconnecting tract...

Lower urinary tract symptoms (LUTS), including urinary incontinence, urgency and nocturia, affect approximately half of women worldwide. Current diagnostic methods for LUTS are invasive and costly, while available treatments are limited by side effects leading to poor patient compliance. In this study, we aimed to identify urine metabolic signatures associated with LUTS using proton nuclear magnetic resonance ((1)H-NMR) spectroscopy. A total of 214 urine samples were collected from women attending tertiary urogynaecology clinics (cases; n=176) and healthy control women attending general gynecology clinics (n=36)...

Hodgkin lymphoma (HL) commonly presents as nodal disease, but in a subset of cases, the disease primarily develops in extranodal sites. Primary classical HL of the gastrointestinal (GI) tract is an extremely rare occurrence. Primary nature of the disease is confirmed after a complete lymphoma work up including chest radiograph, computed tomography scan, peripheral blood, and bone marrow studies. Only a few cases of primary GI lymphomas with limited immunohistochemical or molecular confirmation have been reported in literature...

We report a case of intrapulmonary ectopic liver associated with Scimitar syndrome. A two month old male child who presented with features of congestive cardiac failure underwent extensive cardiac and radiological investigations and was diagnosed with Scimitar syndrome. He was also found to have a mass in the lower lobe of the right lung, the possibilities being either a pulmonary sequestration or a diaphragmatic hernia. As his dyspnea progressively worsened, a right lower lobectomy was performed at the age of two years...

Neuroendocrine tumors (NETs) are neoplasms arising from dispersed neuroendocrine cells, localized to the gastrointestinal tract (GIT), lungs, adrenal medulla, and other sites. The term "carcinoid tumor" is usually limited to NETs of the lung and GIT. Ovarian carcinoids are uncommon, accounting for 0.1% of ovarian malignancies and 5% of all NETs. Primary ovarian tumors arise in pure form or as a component of teratomas, while ovarian NET metastases are predominantly from gastrointestinal primaries. To the best of our knowledge, there are only two previous reports of bronchopulmonary carcinoids (PCs) metastasizing to the ovaries...

Neurotrophins are present in the gastrointestinal tract where they participate in the survival and growth of enteric neurons, augmentation of enteric circuits, elevation of colonic myoelectrical activity and also in different aspects of colitis. Previous studies largely focused on the role of neural and mucosal neurotrophins in gut inflammation. The expression of neurotrophins in colonic smooth muscle cells (SMCs) and the interactions of this potential source with colitis has not been studied in the gut. The expression of NGF, BDNF, NT-3 and TN-4 in SMCs from longitudinal and circular muscle layers of rat colon from normal and Dextran sodium sulphate (DSS)-induced colitis rats was measured by ELISA...

PURPOSE: In vivo drug dissolution in the gastrointestinal (GI) tract is largely unmeasured. The purpose of this clinical study was to evaluate the in vivo drug dissolution and systemic absorption of the BCS Class IIa drug ibuprofen under fed and fasted conditions by direct sampling of stomach and small intestinal luminal content. Expanding current knowledge of drug dissolution in vivo will help to establish physiologically relevant in vitro models predictive of drug dissolution. METHODS: A multi-lumen GI catheter was orally inserted into the GI tract of healthy human subjects...
