Advances in synthetic biology and microbiology have enabled the creation of engineered bacteria which can sense report on intracellular extracellular signals. When deployed vivo these whole-cell bacterial biosensors act as sentinels to monitor biomolecules interest human health disease settings. This is particularly interesting context gut microbiota, interacts extensively with host throughout ...

Plasma membranes from bovine corpora lutea have been purified by sucrose density gradient centrifugation. The purified membranes, in addition to binding 1251-hCG, also possess hCGstimulated adenylate cyclase and Na-K-ATPase. The relative purification of 1251-hCG binding, adenylate cyclase and Na-KATPase on the basis of the specific activities in the whole homogenate were 7.8, 6.4 and 2.6, respe...

BACKGROUND Intestinal microorganisms affect host physiology, including ageing. Given the difficulty in controlling for human studies of the gut microbiome, mouse models provide an alternative avenue to study such relationships. In this study, we report on the complete genome of "Faecalibaculum rodentium" ALO17, a bacterium that was isolated from the faeces of a 9-month-old female C57BL/6J mouse...

bacteria play an important role in the initiation and progression of diseases (not only in disease but affect health status of individual). populations of digestive microflora in chicken gut change with age and also affected by diet, stressors, and performance enhancers as well as in disease conditions. the aim of the pre-sent study was to know bacterial makeup in chicken gut, using denaturing ...

We examined whether dietary intake of cattle liver-supplemented food induces reproductive effects in dams and developmental effects in embryos in the mouse model. Seven groups of 19 to 35 female mice each were given either powdered food or the food supplemented with crude liver homogenate, its lipophilic component, the defatted liver homogenate or vitamin A (retinol palmitate) during a 25-d per...

The wireless motility/pH capsule (WMC) is an orally ingested, nondigestible, data recording device that enables the simultaneous assessment of regional and whole gut transit. Approved by the US Food and Drug Administration for the evaluation of patients with suspected delayed gastric emptying and the evaluation of colonic transit time in patients with chronic idiopathic constipation, this capsu...

Using digital motion analysis, the ontogeny of the cholinergic, tachykinin and pituitary adenylate cyclase-activating polypeptide (PACAP) control systems was studied in zebrafish Danio rerio larvae, in vivo. For the first time we show that the regular propagating anterograde waves that occur in the zebrafish larval gut before and around the onset [at 5-6 days post fertilization (d.p.f.)] of fee...
