13. Garlic supplemented diet attenuates gentamicin nephrotoxicity ın rats
Purpose To demonstrate the effect of a 4% pulverized garlic supplemented diet on the nephrotoxicity induced by gentamicin in rats. Materials and Methods Twenty four healthy male Wistar rats, weighing between 220 - 260grams, were divided into three groups. The rats were randomly assigned to either the gentamicin injection without garlic supplementation g

14. Glucosamine and chondroitin sulfate association increases tibial epiphyseal growth plate proliferation and bone formation in ovariectomized rats
OBJECTIVE: The growth plate consists of organized hyaline cartilage and serves as a scaffold for endochondral ossification, a process that mediates longitudinal bone growth. Based on evidence showing that the oral administration of glucosamine sul

15. Efeito do sulfato de condroitina e glucosamina na reparação de defeitos osteocondrais experimentais no côndilo femoral de cão / Effect of chondroitin sulfate and glucosamine to repair experimental osteochondral defects in the femoral condyle of dog
The aim of this research was to evaluate the influence of chondroprotective veterinary supplement (nutraceutic) composed of glucosamine and chondroitin sulfate in the repair of osteochondral defects induced in femoral lateral condyle of dogs, by clinical, radiographic, macroscopic, histologic and morfometric analysis. We also aimed to test the safety of the

16. Participation of N-acetyl-D-glucosamine carbohydrate moieties in the recognition of Schistosoma mansoni sporocysts by haemocytes of Biomphalaria tenagophila
Lectin-carbohydrate binding may be involved in the recognition of Schistosoma mansoni sporocysts by haemocytes of Biomphalaria; therefore, we tested if this interaction is associated with snail resistance against Schistosoma infection. In vitro data showed that most of the S. mansoni sporocysts cultured with haemocytes from Biomphalaria glabrata BH, a highly

17. Design, synthesis and In Vitro evaluation on glucosamine-6P synthase of aromatic analogs of 2-Aminohexitols-6P
A glicosamina-6-fosfato sintase (GlmS) catalisa a formação de glicosamina-6-fosfato a partir de frutose-6-fosfato. Esta é a primeira etapa da via biossintética de aminoaçúcares, componentes estruturais importantes da parede celular de fungos e bactérias. Este trabalho descreve o planejamento, a síntese e a avaliação da atividade inibitória da GlmS

18. Produção e composição dos polissacarídeos extracelulares de Planktothrix agardhii (Cyanobacteria) e suas relações com bactérias no reservatório de Barra Bonita
The organism Planktothrix agardhii belongs to one of the two most abundant genera in the world among the phytoplankton (the other is Microcystis sp.). Nevertheless, the genus Planktothrix is potentially toxic, producing microcystins and anotoxinas, which makes relevant knowledge of the biology of species that produce large biomass, as the case of P. agardhii

19. Efeito de características estruturais da quitosana sobre sua interação com filmes de Langmuir como modelo de biomembrana / Effects from the structural characteristics of chitosan on its interaction in Langmuir films as biomembrane models.
Chitosans are polysaccharides used in medicine, pharmacy, dentistry and in the inhibition of microorganisms growth (eg. as bactericidal agent). In these applications their action should depend on the interaction with cell membranes, which is difficult to verify because isolating a membrane is not easy. An alternative is to investigate the interaction with me

20. Análise de glicosaminoglicanos e proteoglicanos em linhagens tumorais de próstata / Analysis of glycosaminoglycans and proteoglycans in prostate cancer cell lines
Proteoglycans (PG) are cell surface, extracellular matrix and citoplasmatic granule macromolecules, that play an important role in cellcell and cell-matrix interactions. Several studies indicated that significant changes in PG content occur in the tumor stroma of epithelial neoplasms and that these alterations influence tumor growth and invasion. In this stu

21. Resistance of melanized yeast cells of Paracoccidioides brasiliensis to antimicrobial oxidants and inhibition of phagocytosis using carbohydrates and monoclonal antibody to CD18
Paracoccidioides brasiliensis, a thermal dimorphic fungal pathogen, produces a melanin-like pigment in vitro and in vivo. We investigated the involvement of carbohydrates and monoclonal antibody to CD18, on phagocytosis inhibition, involving macrophage receptors and the resistance of melanized fungal cells to chemically generated nitric oxide (NO), reactive

22. Evaluating conditions for the formation of chitosan/gelatin microparticles
Chitosan/gelatin microparticles were prepared by complex coacervation. Three chitosan (CH) samples, with different acetylation degrees and intrinsic viscosities, were used together with commercial gelatin (G) samples. Microparticles formation was investigated at various CH/G ratios, within the pH range of 3.5 to 6.0. Reactions were carried out at 40 and 60 �

23. Síntese de potenciais agentes antifúngicos inibidores de glicosamina-6-fosfato síntase.
The aminosugars are very important structural components of bacteria and fungi cell walls. Glucosamine-6-phosphate synthase (GlmS), which catalyses the first step of the aminosugar biosynthetic pathway i.e. the formation of D-glucosamine-6-phosphate from D-fructose-6-phosphate, is therefore an interesting target in the fight against microorganisms. In this w

24. Computational analysis suggests that virulence of Chromobacterium violaceum might be linked to biofilm formation and poly-NAG biosynthesis
Groups of genes that produce exopolysaccharide with a N-acetyl-D-glucosamine monomer are in the genome of several pathogenic bacteria. Chromobacterium violaceum, an opportunistic pathogen, has the operon hmsHFR-CV2940, whose proteins can synthesize such polysaccharide. In this work, multiple alignments among proteins from bacteria that synthesize such polysa
