The ruminant gastrointestinal tract (GIT) faces the challenge of protecting the host from luminal contents and pathogens, while supporting the absorption and metabolism of nutrients for growth and maintenance. The GIT of the calf in early life undergoes some of the most rapid microbial and structural changes documented in nature, and these adaptations in GIT function make the young calf susceptible to GIT diseases and disorders. Despite these challenges, the calf's GIT has a certain degree of plasticity and can sense nutrient supply and respond to bioactive ingredients...

BACKGROUND: Helicobacter pylori infection has become more and more resistant to conventional first-line treatment regimens. So, there is a considerable interest in evaluating new antibiotic combinations and regimens. Nitazoxanide is an anti-infective drug with demonstrated activity against protozoa and anaerobic bacteria including H. pylori. This work is designed to evaluate the efficacy and safety of a unique triple nitazoxanide-containing regimen as a treatment regimen in Egyptian patients with H...

AIM: To investigate the clinical and pathogenetic features of the non-acidic types of gastroesophageal reflux disease (GERD) and to evaluate the impact of combined therapy versus monotherapy on the course of this disease. SUBJECTS AND METHODS: The investigation enrolled 62 patients with non-acidic GERD. The follow-up period was 6 weeks. The patients were divided into 2 groups: 1) weakly acidic gastroesophageal refluxes (GER); 2) weakly alkaline GER. Then each group was distributed, thus making up 4 groups: 1) 19 patients with weakly acidic GER who received monotherapy with rabeprazole 20 mg/day; 2) 21 patients with weakly acidic GER had combined therapy with rabeprazole 20 mg and itopride; 3) 8 patients with weakly alkaline GER who received ursodeoxycholic acid (UDCA) monotherapy; and 4) 14 patients with weakly alkaline GER who had combined therapy with UDCA and itopride, The clinical symptoms of the disease, the endoscopic pattern of the upper gastrointestinal tract (GIT) mucosa, histological changes in the esophageal and gastric mucosa, and the results of 24-hour impedance pH monitoring were assessed over time...

Primary urinary Bladder Adenocarcinoma (PBA) is an uncommon neoplasm and can cause diagnostic difficulties due to histologic similarities with adenocarcinomas of adjacent structures like Gastrointestinal Tract (GIT) and prostate, since involvement of the bladder by metastasis or direct spread can occur. Seven cases of bladder adenocarcinomas were diagnosed during a period of four years in a tertiary care hospital. Patient's age ranged from 26-78 years with a male predilection. Three cases were signet ring type adenocarcinomas, two cases were subtyped as enteric variant, one as mucinous variant and one as adenocarcinoma Not Otherwise Specified (NOS) variant...

Imaging and analyzing the locomotion behavior of small animals such as Drosophila larvae or C. elegans worms has become an integral subject of biological research. In the past we have introduced FIM, a novel imaging system feasible to extract high contrast images. This system in combination with the associated tracking software FIMTrack is already used by many groups all over the world. However, so far there has not been an in-depth discussion of the technical aspects. Here we elaborate on the implementation details of FIMTrack and give an in-depth explanation of the used algorithms...

Pneumocystis jirovecii pneumonia (PCP) is a life-threatening infection in hematology. Although occasionally reported, the role of interhuman transmission of P. jirovecii in PCP, compared to that of reactivation, remains an unresolved question; the recommendation to isolate PCP patients in the hematology ward are not well evidence-based. Following an unexpected increase in the number of febrile pneumonia patients with P. jirovecii DNA detected in respiratory samples in our hematology ward, we explored 12 consecutive patients from November 2015 to May 2016...

The aim of this review is to summarize the effect in host energy metabolism of the production of B group vitamins and short chain fatty acids (SCFA) by commensal, food-grade and probiotic bacteria, which are also actors of the mammalian nutrition. The mechanisms of how these microbial end products, produced by these bacterial strains, act on energy metabolism will be discussed. We will show that these vitamins and SCFA producing bacteria could be used as tools to recover energy intakes by either optimizing ATP production from foods or by the fermentation of certain fibers in the gastrointestinal tract (GIT)...

BACKGROUND: Recent advances in high-throughput sequencing allow for much deeper exploitation of natural and engineered microbial communities, and to unravel so-called "microbial dark matter" (microbes that until now have evaded cultivation). Metagenomic analyses result in a large number of genomic fragments (contigs) that need to be grouped (binned) in order to reconstruct draft microbial genomes. While several contig binning algorithms have been developed in the past 2 years, they often lack consensus...

Recent sequencing revolution driven by high-throughput technologies has led to rapid accumulation of 16S rRNA sequences for microbial communities. Clustering short sequences into operational taxonomic units (OTUs) is an initial crucial process in analyzing metagenomic data. Although many heuristic methods have been proposed for OTU inferences with low computational complexity, they just select one sequence as the seed for each cluster and the results are sensitive to the selected sequences that represent the clusters...

The relatively non-toxic family of cucurbit[n]uril, Q[n], have shown considerable potential in vitro as drug delivery agents, with only a few examples of pharmacokinetic (PK) studies for drug⊂Q[n]. Drug-free Q[n] PK studies are the next step in determining the pharmacological applicability in their drug delivery potential. The results for the first PK and bio-distribution of drug-free (14)C-Q[7] are described for administration via intravenous (i.v.) and intraperitoneal (i.p.) dosing. A study of oral administration of drug-free (14)C-Q[8] has also been undertaken to determine the time course for the gastrointestinal tract (GIT), absorption and subsequent bio-distribution...
