CONTEXT AND OBJECTIVE There is controversy regarding which imaging method is best for identifying early degenerative alterations in intervertebral discs. No correlations between such methods and histological finds are presented in the literature. The aim of this study was to correlate the thickness of intervertebral discs measured on simple radiographs with the degree of degeneration seen on ma...

In vitro the antibacterial activity of the Acetone, Methanol and Ethanol extracts of three marine algae from Ennore beach near Chennai (coast of Tamil Nadu) were tested. The test organism includes Gram negative bacteria such as Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Gram positive bacteria such as Staphylococcus aureus. In this study, agar well diffusion test techniq...

Salmonellosis is a common problem in poultry farms of our country. Indiscriminate use of antibiotic to control the disease results drug resistance and limits the therapeutic possibilities in the treatment of the disease. This study was conducted during the period from January to May 2006 at Gobindapur of Dinajpur district. The present study was undertaken to determine the seroprevalence of salm...

INTRODUCTION Enteric fever is caused by Salmonella enterica serovars Typhi and Paratyphi A, B and C. It is a significant public health issue in Pakistan, which is exacerbated by a high level of resistance some isolates display to drugs routinely used in treatment. Azithromycin may be a treatment option for such isolates. METHODOLOGY We determined the minimum inhibitory concentrations (MICs) o...

BACKGROUND Loads acting on scoliotic spines are thought to be asymmetric and involved in progression of the scoliotic deformity; abnormal loading patterns lead to changes in bone and disc cell activity and hence to vertebral body and disc wedging. At present however there are no direct measurements of intradiscal stresses or pressures in scoliotic spines. The aim of this study was to obtain qua...

1. Discs cut from tobacco leaf tissue infected with tobacco mosaic virus and cultured in water contain less non-protein nitrogen than comparable uninfected discs during the time at which TMV is formed. This deficiency disappears when virus formation ceases. Discs cultured in nutrient solution form about twice as much TMV as discs cultured in water. The maximum non-protein nitrogen deficiency is...

Over the last decade, it has become clear that organismal form is largely determined by developmental and evolutionary changes in the growth and pattern formation of tissues. Yet, there is little known about how these two integrated processes respond to environmental cues or how they evolve relative to one another. Here, we present the discovery of vestigial wing imaginal discs in worker larvae...

statement of problem: surface staining of resin composite by dietary factors may be modified by the placement of a low-viscosity surface sealant aimed at reducing surface voids and defects occurring after light-curing and polishing. objectives: the aim of this study was to investigate the staining effect of various drinks and temperatures on the surface sealant (fortify plus™) sealed on a nano-...

Background Urinary Tract Infection (UTI) is a common contagion among men and women with the incidence relatively higher among women due to their differing anatomy. An understanding of the kind of pathogens implicated in urinary tract infections as well as antibiotic susceptibility profiling may help the clinician make rationally correct empirical choice in their treatment. Objective This stud...
