Abstract

To find the effect of the fertilizer factory environment on serum prostatic specific antigen (PSA) levels. A cohort comparative study. The study was conducted at Immunoassay Laboratory of MINAR, Multan from June 2002 to January 2004. A total of 205 workers, all male, of Pak Arab Fertilizer Factory, Multan had their prostatic specific antigen (PSA) estimated. The age of the workers varied between 22 to 65 years (mean age = 48.3 +/- 8.5 years). The people belonged to various working groups and most of them were on normal Pakistani diet. They had been residing/working in the factory area for a period varying from 5 to 30 years. PSA levels were also estimated in 118 normal persons to serve as a control group. The age of these persons varied from 19 to 64 years. These were mostly hospital staff and general public not residing in the factory area and had no history of prostatic disease. Sensitive and specific immunoradiometric assay techniques were applied to measure the PSA concentrations in serum. Observed PSA levels in this population were between 0.2 and 11.5 ng/ml. Overall mean PSA level was 1.9 +/- 0.84 ng PSA/ml. Mean PSA level observed in control group was 0.73 +/- 0.64 ng/ml (upper 95% limit was 3.2 ng/ml). Comparison of PSA...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.
