Lipopolysaccharide (LPS) derived from Gram-negative bacteria activates plasma membrane signaling via Toll-like receptor 4 (TLR4) on host cells and triggers innate inflammatory responses, but the underlying mechanisms remain to be fully elucidated. Here we reveal a role for annexin A2 (AnxA2) in host defense against infection as anxa2(-/-) mice were highly susceptible to Gram-negative bacteria-i...

MateRials and Methods: 35 male Sprauge Dawley rats were divided into 5 groups; each group consisted of 7 rats. Reverse abdominoplasty model was used in all groups except group 1(Only TRAM flap). Right inferior epigastric artery pedicled, 5x2.5 cm sized TRAM flap was performed 2 weeks after abdominoplasty in groups 2 and 4 and 4 weeks after in groups 3 and 5. ASVF cells were injected locally dur...

An experimental survey of CH absorption near the QojC?) and Qlc(7) lines of the {A2A (v=0) ♦ XZn (v=0» band was obtained at 2840°K, 0.2 atm using a remotely located cw ring dye laser source and a shock tube. Mixtures of methane and argon were shock heated to provide reproducible peak concentrations of CH, and narrow-line absorption was measured in repeated experiments with the laser set at diff...

The analysis of the stress-strain state which occurs in the wheel-railtrack assembly of the common mean of urban passenger transportation (tram) represents an issue of high interest due to the fact that the mentioned assembly is subjected to high level of wear resulting in high costs for maintenance and operation at optimum parameters. The high level of wear represents an important source of vi...

PURPOSE To investigate the experimental model for obtaining adipose tissue, isolation, characterization of mesenchymal stem cells and evaluation of their distribution in the tram flap in rats. METHODS Five rats of Wistar were randomly assigned to two groups. In group I, three animals underwent removal of adipose tissue in the groin procedure to establish the experimental model and obtain a ce...

The Zagreb 2020 earthquake severely damaged the historic centre of city. Most damage occurred on masonry residential buildings, many which are situated very close to tram track. Although traffic-induced vibrations generally do not affect surrounding they can be harmful buildings by a previous earthquake. Vibrations could contribute further propagation existing cracks. effect depends factors, on...
