Abstract

Our aim was to report clinical and biochemical outcomes of transperineal interstitial permanent prostate brachytherapy in the treatment of Japanese patients with clinically organ-confined prostate cancer in Hawaii. Ninety-five Japanese patients underwent transperineal interstitial permanent prostate brachytherapy using either iodine-125 or palladium-103 for clinical T1c-T2b N0 M0 prostate cancer. These procedures were carried out between December 1998 and December 2002 at The Queen's Medical Center in Honolulu, Hawaii. Prostate-specific antigen measurements were collected from all patients at follow up. Biochemical failure was defined by three consecutive rises in prostate-specific antigen levels, based on the criteria of the American Society for Therapeutic Radiology and Oncology Consensus panel. The median patient age was 71 years (range, 46-87 years). Thirty-six patients were implanted with either iodine-125 or palladium-103 as monotherapy; 59 patients received moderate-dose external beam irradiation first, followed by a prostate brachytherapy boost. The median follow-up length, calculated from the day of implantation, was 801 days (range, 237-1421 days). During this follow-up period, The Kaplan-Meier estimate of freedom fro...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.
