ABSTRACT:
Nanotechnology is the technology of nanoparticles which are made of polymers of synthetic or natural origin. Nanoparticle is a collective name for nanospheres and nanocapsules of size from 10-1000nm. Nanocapsules are vesicular systems in which drug is confined to a cavity surrounded by a unique polymer membrane. Nanospheres are matrix systems in the drug are physically and uniformly dispersed. Nanotechnology is the design, characterization, production on and application of structures, devices and systems by controlling shape and size on the nanoscale. Nanotechnology in medicine is referred to as nanomedicine and involves the implementation of technologies that exist or function at the cellular and levels medical use.

I. INTRODUCTION

1.1.            WHAT IS PROSTATE CANCER?
Prostate cancer is the most common type of cancer in men and is the second leading cause of cancer-related deaths in men worldwide. It is a disease of the prostate gland in which malignant cells form in the tissues of the prostate and multiply out of control. These cells often metastasize to other parts of the body, like the rectum, the bladder and especially, the bones and the lymph nodes. It generally arises near the surface of the gland so that it can be diagnosed easily by digital rectal examination (DRE). Depending on the extent of metastasis, the prostate cancer tissue has been graded using the Gleason System into a score of 2 to 10 or into four stages I-IV (or, A-D), indicating the likelihood of spreading of the disease to other parts of the body.

Although several types of cells are found in the prostate, over 99% of the cancers occur in the gland cells only (cells which make the prostate fluid which is added to the semen). Such type of cancer is termed as adenocarcinoma. The region of prostate gland where the adenocarcinoma is most common is the peripheral zone.  Other types of cancer can also start in the prostate gland, including sarcomas (like leiomyosarcoma and rhabdomyosarcoma), small cell carcinomas, and transitional cell carcinomas, although they are extremely rare. Generally, the cancer grows and spreads very slowly. Early prostate cancer most often causes no symptoms. Sometimes, however there are signs and symptoms very close to those of benign prostatic hyperplasia (BPH).

ABSTRACT:
Brugada syndrome is a genetic cause of sudden cardiac arrest characterized by abnormal electrocardiographic (ECG) pattern in the right precordial leads either at rest or after provocation. In this condition, sudden death may occur due to polymorphic ventricular tachycardia or ventricular fibrillation. In approximately 30% of patients, sudden cardiac arrest is the initial clinical manifestation of Brugada syndrome.

ABSTRACT:
This is an inherited arrhythmia that causes the bottom chambers of the heart (the ventricles) to beat so fast that they can prevent the blood from circulating efficiently in the body. When this situation occurs (called ventricular fibrillation), the individual will faint and may die in a few minutes if the heart is not reset. While this is a disease that usually affects people in their 30's, it has actually been described at all ages. So it is important to screen everybody in a family. Not everybody who has the disease will have arrhythmias. However, we cannot know yet who will be OK and who will have problems. If you have had fainting spells related to Brugada syndrome, our experience indicates that you are at very high risk of having them again.

ABSTRACT:
Many different types of laboratory fermentors and bioreactors are used worldwide. The selection of a good quality bioreactor is not easy. Some advantageous parameters found in one product are cancelled out by other draw backs in the same system. Good high quality bioreactors are very expensive. Even then ease of use is not assured. The question arises, whether it is possible to construct a bioreactor, which would satisfy most requirements. The most important are high quality and easy to use, perfect sterility, precise measurement, control and recording of all important culture parameters and lasts but not lasts, and the bioreactor shouldn’t expensive!
