Evaluation of antibiotic susceptibility of Lactobacillus plantarum isolated fro...

Nowadays the use of fermentative microbiota in food products is researched in order to confer protection to the products and furnish health benefits to consumers The aim of this work was to evaluate antibiotics susceptibility of Lactobacillus plantarum isolated from fermented traditional meat products in order to select them to be used as starters or protective bacteria on fermented meat products. The susceptib...

Biomechanical and physicochemical characterization of the rat’s osteoporotic bone

Com o apoio RAADRI. ; Abstract de apresentação de poster em conferência. ; Osteoporosis is a clinical condition characterized by an increased risk of bone fracture. Structural fragility seems to result from a reduction in bone mass due to a decreased mineral content and impaired/altered protein synthesis. Despite the established knowledge on osteoporosis, little is known on how these compositional changes may...

Antimicrobial susceptibility assessment of Campylobacter on outdoor iberian pig...

Both Campylobacter and Salmonella are considered the most frequent bacterial causes of human enteritis in industrialized countries. The consumption of raw or undercooked poultry and pork contaminated meat products are the main sources of human infection. The prevalence of Campylobacter and Salmonella was determined in the present work for extensive production Iberian pig sows, Sus mediterraneus. Samples were co...

The behavior of novel hydrophilic composite bone cements in simulated body fluids

Composite bone cements were formulated with bioactive glass (MgOOSiO2O3CaO ! P2O5) as the filler and hydrophilic matrix. The matrix was composed of a starch/cellulose acetate blend (SCA) as the solid component and a mixture of methylmethacrylate/acrylic acid (MMA/AA) as the liquid component. The curing parameters, mechanical properties, and bioactive behavior of these composite cements were determined. The addi...

Regulation mechanisms of bone metabolism.

The bone is continuously in a remodelling process. Bone mass is maintained in a continuous balance between its destruction and formation. Bone remodelling proceeds in a highly regulated cycle in which osteoclasts adhere to bone and subsequently remove it by acidification and proteolytic digestion and the osteoblasts secrete a organic matrix which is calcified into new bone. Bone remodelling is the cellular basi...
