Homeostasis is the ability of physiological systems to regain functional balance following environment or experimental insults and synaptic homeostasis has been demonstrated in various species following genetic or pharmacological disruptions. Among environmental challenges, homeostatic responses to temperature extremes are critical to animal survival under natural conditions. We previously repo...

Urotensin II (UII), which acts on the G protein-coupled urotensin (UT) receptor, elicits long-lasting vasoconstriction. The role of UT receptor internalization and intracellular trafficking in vasoconstriction has yet not been analyzed. Therefore, UII-mediated contractile responses of aortic ring preparations in wire myography and rat UT (rUT) receptor internalization and intracellular traffick...

Evodiamine (EVO) and rutaecarpine (RUT) are promising anti-tumor drug candidates. The evaluation of the anti-proliferative activity and cellular uptake of EVO and RUT in 3D multicellular spheroids of cancer cells would better recapitulate the native situation and thus better reflect an in vivo response to the treatment. Herein, we employed the 3D culture of MCF-7 and SMMC-7721 cells based on ha...

Helicobacter pylori (H. pylori) remains a prevalent chronic infection in the developing countries. H.pylori is an important agent associated with peptic ulcer disease, chronic gastritis and gastric malignancies. It can be detected by various invasive (rapid urease test and histology) and non-invasive tests (stool antigen test, urea breath test and serology). The aim of this study was to compare...

Background: Helicobacter pylori (H. pylori) is considered as one of the most prevalent gastric infections which cause chronic gastritis and predispose to cancer stomach. So, diagnosis and eradication should be rapid to decrease the risk of gastric cancer. Aim of the study: To evaluate the role of rapid urease test (RUT) and faecal antigen test (FAT) added to serological test for rapid diagnosis...

ABSTRACT: A model is developed to minimize the sum of road construction plus forwarding costs with the constraint that rut depth caused by the forwarder cannot exceed a maximum depth during the anticipated season of operation. Road spacing, forwarder trail spacing, and forwarder capacity are used as decision variables in developing the transportation plan. The total cost was minimized using the...

BACKGROUND Rut-C30 is a cellulase-hyperproducing Trichoderma reesei strain and, consequently, became the ancestor of most industry strains used in the production of plant cell wall-degrading enzymes, in particular cellulases. Due to three rounds of undirected mutagenesis its genetic background differs from the wild-type QM6a in many ways, of which two are the lack of a 83 kb large sequence in s...

Complexes between oxovanadium (IV) cation and flavonoid derivatives were developed recently in order to increase the intestinal absorption and to reduce the toxicity of vanadium compounds. For these reasons, is interesting to investigate the complexation process between flavonoid rutin (Rut) and vanadyl cation in order to isolate new complexes. Two new complexes [VO(Rut)(H2O)2](SO4)0.5 x 2 H2O ...

Selecting the appropriate tyre configuration and settings for heavy farm vehicles is important to ensure that soil compaction power loss in rolling resistance are minimised traction optimised. This study investigated effect of front-wheel assist (FWA, ≈75 kN) four-wheel drive (4 WD, ≈100 tractors fitted with different configurations (single, dual), sizes inflation pressures on strength (a proxy...

Flavonoid-containing food supplements are widely used as antioxidants, and the continuous use of these with other drugs can lead to clinically significant interactions between drugs. The medications in systemic circulation mainly transported by serum albumin, a major transport protein. This study evaluated rutin (RUT), naringenin (NAR), sinapic acid (SIN) most abundant protein, bovine albumin (...
