The impact of an inherited BRCA2 mutation on the prognosis women with breast cancer has not been well documented. We studied effects oestrogen receptor (ER) status, other prognostic factors and treatments survival in a large cohort carriers. identified 285 patients 999del5 matched them 570 non-carrier patients. Clinical information was abstracted from patient charts pathology records supplemented by evaluation tumour grade ER status using archived tissue specimens. Univariate multivariate...

Reliable, automated, and user-friendly solutions for the identification of sleep stages in home environment are needed various clinical scientific research settings. Previously we have shown that signals recorded with an easily applicable textile electrode headband (FocusBand, T 2 Green Pty Ltd) contain characteristics similar to standard electrooculography (EOG, E1-M2). We hypothesize electroencephalographic (EEG) using enough EOG order develop automatic neural network-based staging method...

Purpose The purpose of this study is to estimate the effects gender composition in workplace on employee job satisfaction and commitment. Design/methodology/approach data were collected both organizational levels at three different points time organizations with more than 70 employees. Multi-level mixed-effects ordered logistics regressions used account for multi-level nature dependent variables. Findings Employees gender-balanced workplaces show higher commitment those female-dominated or...

Loss of surface expression class I major histocompatibility antigens is commonly observed in malignant tumors and has been considered one the mechanisms for escape from cytotoxic T cells. However, natural killer cells kill lacking HLA antigens. In present study, we characterized by immunohistochemistry breast carcinomas 187 patients with TNM stages II, diagnosed 1981-1984, using beta(2)-microglobulin as a marker evaluated effect on survival follow-up up to 14 years. The largest group (48%)...

Fas ligand (FasL) is expressed on some cancers and may play a role in the immune evasion of tumour. We used immuno-histochemistry to study expression FasL tissue samples from breast cancer patients, as well normal tissue. Our results show that are co-expressed both tumours. mRNA were fresh malignant tissue, cultured epithelium cell lines. Flow cytometry analysis live cells failed detect surface or cells; however, stained positive for after permeabilization. was detected T47D MCF-10A lines...

Abstract The present study examined the influence of age and gender on T cell populations in lacrimal gland. Lacrimal (exorbital) glands were obtained from male female rats at 19 days (pre‐puberty), 9 weeks (adult) 14 months (mid‐life) tissues processed for subset identification. In females, density total (W3/13 + OX ), helper/inducer (W3/25 ) suppressor/cytotoxic (OX 8 cells underwent a significant increase before, to after puberty. Following this rise, all decreased young adult midlife...

The Icelandic labor market is flexible and adjusts quickly to adverse circumstances as evidenced in the Great Recession, where wages work hours adjusted with a substantial increase unemployment.With recent exponential growth tourism leading strong economic growth, real wage increases bargained for have been greater than productivity, loss competitive position of country.Immigrants make up growing share market, which poses new challenges now that has again slowed.

A persistent unexplained gender wage gap exists in Iceland and women are still a minority as directors, chairs of boards board members within organizations. Organizations required by law to have equality statement, but addition they may be taking various proactive actions towards equality. However, little knowledge on whether these lead more positive perceptions amongst employees. The main objective this study is therefore the relationship between organizational activity (existence statement...

While half of undergraduate students in business are women, only one five full professors the US female. According to pipeline theory, this discrepancy should correct itself through time and more women join ranks professors. However, seems leak, as adjustment is slow. Student evaluations teaching (SET) measures used evaluate faculty. If there a gender bias student evaluations, where female faculty valued less than male faculty, could contribute leaky by reducing women’s promotion...

Abstract Germline mutations in the BRCA genes are associated with highly increased risk of breast and ovarian cancers to a lesser extent prostate pancreatic cancers. Great number variable impact on cancer progression known these worldwide. A single founder mutation has been detected each Icelandic population, making it feasible study influence at population level. The BRCA2999del5 is more frequent can be found approximately 6-7% female patients 40% male Iceland. leads non-functional protein...
