Natural course of human benign prostatic hyperplasia with relation to urinary disturbance

The Prostate

Abstract

To examine the natural course of human benign prostatic hyperplasia (BPH), cases in health care examination with or without slight urinary symptoms were examined by echography. In comparison with these cases, the size of the prostate was examined in patients who received prostatectomy. Prostatic sizes of health care cases varied widely along with increasing age, but could be divided into two groups: increasing or no-change. According to serial determinations of prostatic sizes in the increasing group, the annual growth rate of the prostate was calculated as 1.65 +/- 1.13 and 0.85 +/- 0.44 g in men < 65 years old and in men > or = 65 years old, respectively. Distribution of prostatic sizes as a function of age in health care cases was similar to that in operated patients, showing that the size was not correlated with urinary symptoms or surgical indication. Since uroflow rates decreased along with increasing age in the no-change group of operated patients, aging was a factor in deterioration of uroflow. Between the increasing and the no-change groups in health care cases, differences were found in total cholesterol and neutral fat in serum, in addition to gamma-seminoprotein; the latter may be due to differences in the size of t...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
