Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Regulation of the cytoskeleton is a central feature of cell migration. The formin family of proteins controls the rate of actin nucleation at its barbed end. Thus, formins are predicted to contribute to several important cell processes such as locomotion, membrane ruffling, vesicle endocytosis, and stress fiber formation and disassociation.', 'In this study we investigated the functional role of Formin1-isoform4 (Fmn1-IV) by using genetically null primary cells that displayed augmented protrusive behaviour during wound healing and delayed cell spreading. Cells deficient of Fmn1-IV also showed reduced efficiency of focal adhesion formation. Additionally, we generated an enhanced green fluorescence protein (EGFP)-fused Fmn1-IV knock-in mouse to monitor the endogenous subcellular localization of Fmn1-IV. Its localization was found within the cytoplasm and along microtubules, yet it was largely excluded from adherens junctions.

Observational studies suggest that dietary isoflavones reduce breast cancer risk, and this may be caused in part by effects on endogenous hormone concentrations. Because intestinal bacteria metabolize isoflavones, it was hypothesized that consumption of probiotic bacteria would enhance the biologic effects of isoflavones, including effects on endogenous hormones.', 'Twenty (20) postmenopausal breast cancer survivors and 20 healthy postmenopausal women completed four 42-day diet periods in a randomized, crossover design. They received one of the following: isolated soy protein; isolated milk protein; soy + probiotic capsules; or milk + probiotic capsules. Each protein supplement provided 0.38 g protein/(kg body weight/day) (26.6 +/- 4.5 g protein/day) and soy protein provided 0.64 mg isoflavones/(kg body weight/day) (44.4 +/- 7.5 mg isoflavones/day). Probiotic capsules provided 10(9) colony-forming units Lactobacillus acidophilus (strain DDS-1), Bifidobacterium longum, and 15-20 mg fructo-oligosaccharide.', 'Plasma samples were collected at baseline and after each diet for analysis of estrogens, follicle-stimulating hormone (FSH), androgens, and sex hormone?binding globulin (SHBG).', 'Hormone levels were not affected by soy, probiotic supplements, or equol producer status, and neither cancer status nor equol producer status altered the effects of soy or probiotics. Furthermore probiotics did not alter the effects of soy consumption. Soy protein tended to decrease SHBG compared to milk protein diets (p = 0.05), although both proteins significantly decreased SHBG relative to baseline (p = 0.0001 and p = 0.03).

The oral cavity has been considered a potential reservoir for Helicobacter pylori (H pylori) , from where the organism causes recurrent gastric infections.', 'With this case-control study we tried to evaluate the role of H pylori in the etiology of mucosal inflammation, a condition that compounds the morbid state associated with oral submucous fibrosis (OSF).', 'Subjects ( n = 150) were selected following institutional regulations on sample collection and grouped into test cases and positive and negative controls based on the presence of mucosal fibrosis and inflammation. The negative controls had none of the clinical signs. All patients underwent an oral examination as well as tests to assess oral hygiene/periodontal disease status; a rapid urease test (RUT) of plaque samples was also done to estimate the H pylori bacterial load. We used univariate and mutivariate logistic regression for statistical analysis of the data and calculated the odds ratios to assess the risk posed by the different variables.', 'The RUT results differed significantly between the groups, reflecting the variations in the bacterial loads in each category. The test was positive in 52% in the positive controls (where nonspecific inflammation of oral mucosa was seen unassociated with fibrosis), in 46% of the test cases, and in 18% of the negative controls (healthy volunteers) (chi2 = 13.887; P < 0.01). A positive correlation was seen between the oral hygiene/periodontal disease indices and RUT reactivity in all the three groups.
