Alcohol consumption and prostate cancer: a mini review.

Prostate cancer has become a major public health problem worldwide although the etiology of prostate cancer remains largely unknown. Dietary factors, dietary supplements, and physical activity might be important in the prevention of the disease. In the majority of studies published, it was observed that high consumption of meat, alcohol and dairy products has been linked to a greater risk.

Amplification and co-regulators of androgen receptor gene in prostate cancer.

Prostate cancer is the second most common malignancy among males after lung cancer. The growth of prostate cancer cells depends on the presence of androgens, a group of steroid hormones that include testosterone and its more active metabolite dihydrotestoste-rone. Most prostate cancers are androgen-dependent and respond to the antiandrogens or androgen-deprivation therapy.

Molecular profiling and genomic microarrays in prostate cancer.

In the present review article a global approach regarding the usefulness of genomic microarrays in prostate cancer management, is attempted. Cancer is a multistep process of mutations in key regulatory genes and epigenetic alterations that result in loss of balanced gene expression. A complete knowledge of the interaction between the genetic variability of the neoformation (tumor profiling) and the genetic variability of the host (inherited genome profiling), will be able to determine the better strategy against the cancer and the less toxicity for the patient.

The kinin system--bradykinin: biological effects and clinical implications. Multiple role of the kinin system--bradykinin.

The present review article regarding the kinin system-bradykinin is dealing with the biological effects of the abovementioned entity mediated by specific B1 and B2 receptors as well as with its clinical implications known nowadays. The activation of the kinin system-bradykinin is particularly important in blood pressure regulation and in inflammatory reactions, through bradykinin ability to elevate vascular permeability and to cause vasodilatation in some arteries and veins. Recent data on bradykinin formation and release, synergy with ligands, receptors for bradykinin as well as on bradykinin participation in the mitogenesis process, are given in detail.

Genetic models of human cancer as a multistep process. Paradigm models of colorectal cancer, breast cancer, and chronic myelogenous and acute lymphoblastic leukaemia.

Tumour formations arise as a consequence of alterations in the control of cell proliferation as well as with disorders in interactions between cells and their environment that result in invasion and metastasis. Recent advances in understanding the genetic basis of malignant diseases have been dominated by research in colorectal cancer. Genetic alterations of several proto-oncogenes and tumor-suppressor genes (e.

Giant simple renal cyst complicated with hypertension.

Solitary renal cysts are a common and usually asymptomatic occurrence in older patients. They may be associated with hypertension or abdominal disturbances, as they can be responsible for compression of surrounding tissues and distortion of renal vessels. This report presents an interesting case of a hypertensive patient with a solitary renal cyst of a marked size.

Cell proliferation and cell cycle control: a mini review.

Tumourigenesis is the result of cell cycle disorganisation, leading to an uncontrolled cellular proliferation. Specific cellular processes-mechanisms that control cell cycle progression and checkpoint traversation through the intermitotic phases are deregulated. Normally, these events are highly conserved due to the existence of conservatory mechanisms and molecules such as cell cycle genes and their products: cyclins, cyclin dependent kinases (Cdks), Cdk inhibitors (CKI) and extra cellular factors (i.
