Current studies of human gut microbiome usually do not consider the special functional role of transient microbiota, although some of its members remain in the host for a long time and produce broad spectrum of biologically active substances. Getting into the gastrointestinal tract (GIT) with food, water and probiotic preparations, two representatives of Bacilli class, genera Bacillus and Lactobacillus, colonize epithelium blurring the boundaries between resident and transient microbiota. Despite their minor proportion in the microbiome composition, these bacteria can significantly affect both the intestinal microbiota and the entire body thanks to a wide range of secreted compounds...

The influence of co-ingestion of food emulsions with tomatoes on the bioaccessibility of a model pesticide (chlorpyrifos) was studied. Emulsions were fabricated with different oil contents (0 to 8%), lipid compositions (MCT and corn oil) and particle diameters (d32 = 0.17 and 10 μm). The emulsions were then mixed with chlorpyrifos-contaminated tomato puree, and the mixtures were subjected to a simulated gastrointestinal tract (GIT) consisting of mouth, stomach, and small intestine. The particle size, surface charge, and microstructure of the emulsions was measured as they passed through the GIT, and chlorpyrifos bioaccessibility was determined after digestion...

Cockroaches have been recognized as mechanical vectors of pathogens that can infest humans or animals. A total of 844 adult cockroaches (436 males and 408 females) were caught. In the laboratory, cockroaches were first washed in saturated salt solution to remove ectoparasites and then rinsed with 70% alcohol, dried, and dissected for endoparasites. An overall transport rate of 47.39% was recorded. Six genera of parasites were identified. These were Ascaris (33.76%), Trichuris (11.97%), Capillaria (6.16%), Toxocara (4...

Controlling the rate and extent of protein digestion within different regions of the human gastrointestinal tract (GIT) is important for regulating hormonal responses (such as hunger, satiety, and satiation) and immune responses (such as allergenicity). In this study, hydrogel beads (biopolymer microgels) were fabricated by injecting a solution of anionic alginate molecules into a solution of cationic calcium ions using a vibrating extrusion device. A model food protein (whey protein isolate, WPI) was mixed with the alginate solution prior to bead formation...

BACKGROUND: Patients are seeking out medical information on the Internet and utilizing smartphone health applications ("apps"). Smartphone use has exponentially increased among orthopaedic surgeons and patients. Despite this increase, patients are rarely directed to specific apps by physicians. No study exists querying patient preferences for a patient-centered, orthopaedic smartphone application. OBJECTIVES: The purpose of this study is to 1) determine Internet use patterns amongst orthopaedic patients; 2) ascertain access to and use of smartphones; and 3) elucidate what features orthopaedic patients find most important in a smartphone application...

REVIEW
Michael X Ma, Michael J Bourke
Endoscopic submucosal dissection (ESD) was first conceptually described almost 30 years ago in Japan and is now widely practiced throughout East Asia. ESD expands the boundaries of endoscopic resection (ER) by allowing en bloc resection of large early neoplastic lesions within the gastrointestinal tract (GIT). This offers advantages over other ER techniques by facilitating definitive histological staging and curative treatment of early cancer in selected cases. Indeed the experience of ESD in Eastern countries is significant, and excellent outcomes from high volume centres are reported...

Motivation: The minimizers scheme is a method for selecting k -mers from sequences. It is used in many bioinformatics software tools to bin comparable sequences or to sample a sequence in a deterministic fashion at approximately regular intervals, in order to reduce memory consumption and processing time. Although very useful, the minimizers selection procedure has undesirable behaviors (e.g. too many k -mers are selected when processing certain sequences). Some of these problems were already known to the authors of the minimizers technique, and the natural lexicographic ordering of k -mers used by minimizers was recognized as their origin...

BACKGROUND: Hepatic portal venous gas (HPVG) is rare but potentially serious condition. Main cause of HPVG is bowel ischemia, while detection of HPVG without bowel ischemia may have been increasing possibly due to widespread use of computed tomography. However, little is known about variation in etiologies of HPVG and mortality of HPVG with each etiology. We examined patient backgrounds, underlying diseases, and in-hospital mortality of HPVG patients using a national inpatient database...

BACKGROUND: Early enteral nutrition (EEN) and the continuation of enteral nutrition (EN) are critical factors in burn patients, who typically have higher nutritional needs due to their post-injury hypercatabolic state and their additional need for nutrients to aid in the healing of wounds and skin grafts. In the critically ill patient, EN is the preferred mode of administration; however, controversy exists regarding the concomitant use of EN and intravenous vasopressor agents in the haemodynamically unstable patient...

Pathogenic microorganisms are a potential threat to the agriculture and food industries. Food contamination can be happened in the production levels at any point in the chain by pathogenic microorganisms. Conventional methods, such as those involving antibiotics, disinfectants, and physical methods, are commonly used as microbial control strategies. Owing to the limitations of these methods, such as emergence of resistance, low effectiveness, high cost, and detrimental effects on food, health, and the environment, many countries have adopted laws and regulations restricting their use...

Carefully designed delivery systems are required to encapsulate and protect omega-3 fatty acids in commercial food and beverage products, but then release them at the required site-of-action within the human gastrointestinal tract (GIT). Previously, we showed that the oxidative stability of flaxseed oil (a plant-based source of omega-3 fatty acids) encapsulated in nanoemulsion droplets or calcium alginate microgels (hydrogel beads) was improved using caseinate as a natural antioxidant. In this study, the impact of caseinate on the digestion of flaxseed oil encapsulated in these delivery systems was investigated using a simulated GIT...

Standardized analytical methods, where each B vitamin is extracted from a given sample individually using separate procedures, typically ensure that the extraction conditions provide the maximum recovery of each vitamin. However, in the human gastrointestinal tract (GIT), the extraction conditions are the same for all vitamins. Here, we present an analytically feasible extraction protocol that simulates conditions in the GIT and provides a measure of the content of bioavailable vitamins using LC-MS stable isotope dilution assay...

Intracerebral inoculation of mice with the M1000 strain of mouse-adapted human prions results in the consistent accumulation of PrP(Sc) in the ileum of the gastrointestinal tract (GIT) of mice with clinical signs of prion disease. The accumulation of PrP(Sc) in the ileum is accompanied by caspase activation and loss of immunoreactivity in subpopulations of neurons in the enteric nervous system. This suggests that like neurons in the central nervous system, cells in the enteric nervous system are also susceptible to prion-induced toxicity...

The gastrointestinal tract (GIT) represents the largest interface between the human organism and the external environment. In the lumen and upper part of the mucus layer, this organ hosts an enormous number of microorganisms whose composition affects the functions of the epithelial barrier and the gut immune system. Consequentially, the microorganisms in the GIT influence the health status of the organism. Probiotics are living microorganisms which, in specific conditions, confer a health benefit to the host...

Probiotics are being used as biologic controllers in the prevention of bacterial pathogens as an alternative to antibiotics to improve health and production parameters in fish farming. Fish farming production is severely affected by aflatoxins (AFs) representing a significant problem in aquaculture systems. Aflatoxins exert a substantial impact on production causing disease with high mortality and a gradual decline of reared fish stock quality. Some aspects of aflatoxicosis in fish, particularly its effects on the gastrointestinal tract (GIT), have not been well documented...
