This study was undertaken to examine if glutathione S-transferase (GST) M1, M3, P1, and T1 genotypes affected breast cancer risk in Finnish women. The study population consisted of 483 incident breast cancer cases and 482 healthy population controls. Genotyping analyses were performed by PCR-based methods, and odds ratios (ORs) and 95% confidence intervals(More)
Germline mutations of the putative tumor suppressor gene APC are associated in high frequency with the familial adenomatous polyposis, predisposing the patients to colorectal neoplasia. Similarly, sequence analyses have revealed that in more than half of patients with sporadic colorectal carcinoma or adenoma, the APC gene was mutated. By employing genomic(More)
Clinical follow-up data of 276 colorectal adenocarcinoma patients treated in Kuopio University Hospital between 1976 and 1986 and followed up for a mean of 14 years were analysed. The clinical findings were correlated with tumour-infiltrating lymphocytes (TILs) and with histological and quantitative factors including nuclear parameters and volume-corrected(More)
Apoptotic cells were quantitated by light microscopy in a series of 288 breast carcinomas, and their number (cells/mm2 of neoplastic epithelium, i.e., the apoptotic index, AI) was related to various histopathological features and disease outcome. High AI was associated with tumour necrosis (P = 0.003), lack of tubule formation (P = 0.03), dense stromal(More)
The authors investigated the ability/potencies of 3 microbial volatile organic compounds and a mixture of 5 microbial volatile organic compounds to cause eye and upper respiratory tract irritation (i.e., sensory irritation), with an animal bioassay. The authors estimated potencies by determining the concentration capable of decreasing the respiratory(More)
Superoxide dismutases play a key role in the detoxification of superoxide radicals and thus protect cells from damage induced by free radicals. Within mitochondria manganese superoxide dismutase (MnSOD) provides a major defence against oxidative damage by reactive oxygen species. Polymorphism in the mitochondrial targeting sequence of MnSOD has recently(More)
The increased use of mobile phones has raised the question of possible health effects of such devices, particularly the risk of cancer. It seems unlikely that the low-level radiofrequency (RF) radiation emitted by them would damage DNA directly, but its ability to act as a tumor promoter is less well characterized. In the current study, we evaluated the(More)
Prediction of the clinical outcome of breast cancer is multi-faceted and challenging. There is growing evidence that the complexity of the tumour micro-environment, consisting of several cell types and a complex mixture of proteins, plays an important role in development, progression, and response to therapy. In the current study, we investigated whether(More)
To clarify the existence of a receptor protein for sensory irritants in trigeminal nerve endings, D- [i.e. (+)] and L- [i.e. (-)] enantiomers of alpha- and beta-pinene as models of nonreactive chemicals were evaluated for their potency in outbred OF1 and NIH/S mice using ASTM E981-84 bioassay. All pinenes possess sensory irritation properties and also(More)
Acute effects on the upper and lower respiratory tract due to inhalation exposure to Stachybotrys chartarum (Sc) extract were investigated in mice. In addition, the capacity of the Sc exposure to activate immune system and cause inflammation in the respiratory tract was studied. The inhalation of Sc extract aerosols was observed to provoke sensory(More)
