Intraoperative Performance and Early Postoperative Outcomes Following Phacoemulsification With Three Fluidic Systems: A Randomized Trial.

Purpose: To compare intraoperative performance and early postoperative outcomes following phacoemulsification with two systems using active fluidics and one using gravity-based fluidics.

Methods: In this prospective randomized trial, 200 eyes were randomized to the traditional and Active Sentry groups (n = 80 eyes each) where the Centurion Vision System was used with traditional or Active Sentry (Alcon Laboratories, Inc) hand-pieces, respectively, or the Infinit group (n = 40 eyes) where the Infiniti Vision System (Alcon Laboratories, Inc) was used. Within the traditional and Active Sentry groups, there were two subgroups with low (30 mm Hg) or high (55 mm Hg) intraocular pressure (IOP) used.

Bone Health Status in Indian Overweight/Obese Children.

This cross-sectional study, to assess bone health in Indian overweight, obese children in comparison with healthy controls was conducted in 245 (126 girls) children and adolescents aged 6-17 y in Pune, India. It was found that total body bone mineral content, bone area and bone mineral density adjusted for Tanner stage and weight were significantly lower in obese children as compared to overweight children, which in turn, was significantly lower than normal weight children (p < 0.05).

Association of CYP1A1, GSTM1, and GSTT1 gene polymorphism with risk of oral submucous fibrosis in a section of North Indian population.

Genetic alterations in the genes expressing drug metabolizing enzymes can make an individual susceptible to various cancers. This study detects the polymorphisms at CYP1A1, GSTM1, and GSTT1 genes in a section of North Indian population and determines the susceptibility to oral submucous fibrosis (OSF). In this case-control study one hundred and two OSF patients were genotyped to detect the GSTM1, GSTT1, CYP1A1 polymorphism.

Glutathione-S-transferase M1 and T1 genes and gastric cancer: a case control study in North Indian population.

Background: Difference in the capacity of xenobiotic metabolising enzymes might be an important factor in genetic susceptibility to cancer.

Methods: A case control study involving forty one gastric cancer patients and one hundred and thirty controls was carried out to determine the frequency of GSTM1 and GSTT1 null genotypes. The frequency of GSTM1 and GSTT1 null genotype was observed by carrying out multiplex PCR.

An estimation and evaluation of total antioxidant capacity of saliva in children with severe early childhood caries.

BACKGROUND. The available evidence implicating the involvement of oxidative stress in the caries process suggests that local antioxidant status may be of importance in determining the susceptibility to the caries process. AIM.

Glutathione S-transferase M1 and T1 polymorphism and response to neoadjuvant chemotherapy (CAF) in breast cancer patients.

Purpose: Response to neoadjuvant chemotherapy (NACT) for breast cancer patients cannot be predicted; however, polymorphism of the glutathione S-transferase genes GSTM1 and GSTT1 can modify the response to chemotherapy. The aim of this study was to establish whether there is an association between the polymorphism of GSTM1 and GSTT1 and response to NACT.

Methods: The subjects of this study were 45 patients with locally advanced breast cancer (LABC), who received the cyclophosphamide, adriamycin, and 5-fluorouracil (CAF) regimen as NACT.

Role of GSTM1 and GSTT1 polymorphism: susceptibility to oral submucous fibrosis in the North Indian population.

Molecular epidemiological studies have provided evidence that individual susceptibility to cancer is mediated by both genetic and environmental factors. Several allelic variants of polymorphic glutathione s-transferases (GSTs) show impaired enzyme activity and are suspected to increase the host's susceptibility to various cancers. To determine the association of GST variants with the risk of oral submucous fibrosis (OSF), the distribution of polymorphisms in GSTM1 and GSTT1 was studied in 90 OSF patients and 130 healthy controls.

Genetic polymorphism of CYP3A5 in Indian chronic myeloid leukemia patients.

CYP3A5 is an important genetic contributor to inter-individual differences in CYP3A-dependent clinically important drugs of metabolism and also of various endogenous compounds and environmental contaminants. The CYP3A5*3 allele results in a truncated protein with loss of CYP3A5 expression and CYP3A5*6 is associated with lower CYP3A5 catalytic activity. The polymorphism analysis was performed by PCR-RFLP and some representative cases by direct sequencing.

Increased frequencies of glutathione-S-transferase (GSTM1 and GSTT1) null genotypes in Indian patients with chronic myeloid leukemia.

Inherited differences in the capacity of xenobiotic metabolizing enzymes might be an important factor in genetic susceptibility to cancer. Null genotypes of glutathione-S-transferases (GSTs) exhibit absence of enzymatic activity and are hypothesized to be at increased risk of developing cancers. The aim of the study was to examine whether null genotypes of GSTM1 and GSTT1 confer susceptibility to chronic myeloid leukemia (CML).
