TL;DR: The present study identifies the specific contribution of each COX isoenzyme in hypothalamic, pituitary, and ovarian function and establishes the pathology and rescue of the anovulatory syndrome in the COX-2-deficient mouse.
Abstract: Mice carrying a null mutation for either of the two cyclooxygenase (COX) isoenzymes, necessary for prostanoid production, exhibit several isotype-specific reproductive abnormalities. Mice deficient in COX-1 are fertile but have decreased pup viability, whereas mice deficient in COX-2 fail to ovulate and have abnormal implantation and decidualization responses. The present study identifies the specific contribution of each COX isoenzyme in hypothalamic, pituitary, and ovarian function and establishes the pathology and rescue of the anovulatory syndrome in the COX-2-deficient mouse. In both COX-1- and COX-2-deficient mice, pituitary gonadotropins were selectively increased, whereas hypothalamic LHRH and serum gonadotropin levels were similar to those in wild-type animals (+/+). No significant differences in serum estrogen or progesterone were noted among the three genotypes. Exogenous gonadotropin stimulation with PMSG and hCG produced a comparable 4-fold increase in ovarian PGE2 levels in wild-type and COX...

13 Oct 1999TL;DR: In this paper, the use of passive stopping means acting as passive valves allows the flow of fluids through microchannels to be regulated so as to allow fluids to be mixed or diluted after being introduced via a single channel, or to be split into multiple channels without the need for individual pipetting.
Abstract: Methods of controlling fluid flow through microchannels by use of passive valves or stopping means in the microchannels is presented. The passive valves act as pressure barriers impeding flow of solution past the stopping means until enough force is built up to overcome the force of the pressure barrier. Well planned use of such stopping means acting as passive valves allows the flow of fluids through microchannels to be regulated so as to allow fluids to be mixed or diluted after being introduced via a single channel, or to be split into multiple channels without the need for individual pipetting. Flow through the multiple channels can be regulated to allow a series of sister wells or chambers to all fill prior to the fluid flowing beyond any one of the sister wells or chambers. The filling of sister wells or chambers in this manner allows all wells or chambers to undergo reactions in unison. The use of air ducts to prevent trapping of air in the microchannels is also presented.

TL;DR: Examination of the prevalence of BRCA1 andBRCA2 mutations in an ethnically diverse group of women who were referred for genetic testing found that these mutations were common in women at increased risk for breast and ovarian cancer.
Abstract: Background
In women at increased risk for breast and ovarian cancer, the identification of a BRCA1/2 mutation has important implications for screening and prevention counseling. Uncertainty regarding the role of BRCA1/2 testing in high-risk women from diverse ancestral backgrounds exists due to variability in prevalence estimates of deleterious (disease-associated) mutations in non-White populations. We examined the prevalence of BRCA1/2 mutations in an ethnically diverse group of women referred for genetic testing.

TL;DR: This article identified BRCA1 mutations in 12 of 30 (40%) Canadian families with breast and/or ovarian cancer, including six of the eight families (75%) that contained two cases of early-onset breast cancer.
Abstract: Women who carry mutations in the BRCA1 gene on chromosome 17q have an 85% lifetime risk of breast cancer, and a 60% risk of ovarian cancer. We have identified BRCA1 mutations in 12 of 30 (40%) Canadian families with breast and/or ovarian cancer, including six of the eight families (75%) that contained two cases of early-onset breast cancer and two cases of ovarian cancer. Six frameshift mutations account for all 12 mutant alleles, including nucleotide insertions (two mutations) and deletions (four mutations). Four independent families carried the same 1 basepair (bp) insertion mutation in codon 1755 and four other families shared a 2 bp deletion mutation in codons 22-23. These families were not known to be related, but haplotype analysis suggests that the carriers of each of these mutations have common ancestors.

TL;DR: The CCP score was validated to have significant prognostic accuracy after controlling for all available clinical and pathologic data, and may improve accuracy of risk stratification for men with clinically localized prostate cancer, including those with low-risk disease.
Abstract: Purpose We aimed to validate a previously described genetic risk score, denoted the cell-cycle progression (CCP) score, in predicting contemporary radical prostatectomy (RP) outcomes. Methods RNA was quantified from paraffin-embedded RP specimens. The CCP score was calculated as average expression of 31 CCP genes, normalized to 15 housekeeper genes. Recurrence was defined as two prostate-specific antigen levels ≥ 0.2 ng/mL or any salvage treatment. Associations between CCP score and recurrence were examined, with adjustment for clinical and pathologic variables using Cox proportional hazards regression and partial likelihood ratio tests. The CCP score was assessed for independent prognostic utility beyond a standard postoperative risk assessment (Cancer of the Prostate Risk Assessment post-Surgical [CAPRA-S] score), and a score combining CAPRA-S and CCP was validated. Results Eighty-two (19.9%) of 413 men experienced recurrence. The hazard ratio (HR) for each unit increase in CCP score (range, −1.62 to 2....
