Perceived benefits, motives, and barriers to aqua-based exercise among older adults with and without osteoarthritis.

This study aimed to (a) identify factors that motivate older adults to participate in aqua-based exercise; (b) identify potential barriers; and (c) compare perceptions between older adults with and without osteoarthritis (OA). Fifteen adults above 60 years of age participated in one of three focus groups during which they discussed perceived benefits, motives, and barriers to aqua exercise. Pain reduction was considered a major benefit among those with OA, improved health and fitness was a principal benefit for those without OA.

Relative importance of prenatal and postnatal androgen action in determining growth of the penis and anogenital distance in the rat before, during and after puberty.

Experimental animal studies show that measurement of anogenital distance (AGD) and/or penis length may provide lifelong 'read-outs' of foetal androgen exposure during the masculinization programming window (MPW). However, variation in postnatal androgen exposure may complicate interpretation of such measurements. This is important to clarify if such measurements are to be applied to humans.

Androgen action in the masculinization programming window and development of male reproductive organs.

We have shown previously that deficient androgen action within a masculinization programming window (MPW; e15.5-e18.5 in rats) is important in the origin of male reproductive disorders and in programming male reproductive organ size, but that androgen action postnatally may be important to achieve this size.

Identification in rats of a programming window for reproductive tract masculinization, disruption of which leads to hypospadias and cryptorchidism.

Becoming a phenotypic male is ultimately determined by androgen-induced masculinization. Disorders of fetal masculinization, resulting in hypospadias or cryptorchidism, are common, but their cause remains unclear. Together with the adult-onset disorders low sperm count and testicular cancer, they can constitute a testicular dysgenesis syndrome (TDS).

The prognostic value of early CA125 serum assay in epithelial ovarian carcinoma.

We examined the prognostic value of early serum CA125 assay in 58 patients with advanced epithelial ovarian cancer together with residual disease, age, tumour grade, performance status, and the presence of ascites or adhesions at primary surgery. CA125 was a highly significant predictor of both progression free and overall survival after the first cycle and throughout primary chemotherapy. After the first cycle, CA125 was by far the most significant predictor of progression free survival (P < 0.

The value of the human milk fat globule membrane antigen HMFG2 in epithelial ovarian cancer monitoring: comparison with CA125.

We assayed serum HMFG2 in serial samples from 215 primary epithelial ovarian cancer patients using an 'in-house' single determinant ELISA, 45% of patients with stage I, 54% with stage II, 61% with stage III and 75% with stage IV disease had elevated serum HMFG2. Post-operative levels were significantly related with residual tumour volume (P < 0.005), and fell in the majority of responders, although the association with response to first-line chemotherapy was not significant.

Measurement of placental alkaline phosphatase activity in benign and malignant pleural effusions.

The usefulness of placental alkaline phosphatase (PLAP) as a diagnostic marker of malignancy was assessed in pleural fluid from 60 patients with effusions. Pleural fluid PLAP activities were measured by an enzyme linked immunoassay (ELISA) using the two monoclonal antibodies H17E2 and H317. Similar values were found in groups of patients with primary bronchial tumours (n = 12), secondary malignancies (n = 23), and "benign" conditions (n = 25).

Investigation of the c-neu proto-oncogene related protein, p185, in the serum of primary epithelial ovarian cancer patients.

The relatively high incidence of amplification and overexpression of the neu (c-erb B2/HER-2) oncogene in breast cancer, and its association with poor prognosis, particularly in node negative patients, may allow identification of patients who require aggressive therapy to prevent an early relapse. It's association with ovarian cancer, however, is less well defined than in breast cancer. An ELISA for the c-neu proto-oncogene related protein, p185, has been developed recently using the monoclonal antibodies NB3 and TA1.

Serum placental-like alkaline phosphatase (PLAP): a novel combined enzyme linked immunoassay for monitoring ovarian cancer.

A new combined enzyme linked immunoassay (ELISA) was developed to measure both serum placental-like alkaline phosphatase (PLAP) activity (PLAPA) and concentration (PLAPC) in the same microtitre plate using an Imperial Cancer Research Fund monoclonal antibody, designated H17E2. PLAP A and PLAP C were determined together with an existing marker, CA125 in 397 serial samples from 87 patients with epithelial ovarian cancer. Retrospective assessment showed the sensitivity to increase from 73% with CA125 alone, to 88% using CA125 and PLAP A, and to 93% with all three markers in 261 samples from the patients with known active disease at the time of sampling.
