Abstract

The ability of nitrendipine to control blood pressure (BP) over a 12- or 24-h period was assessed in patients greater than 65 years of age who had a systolic BP (SBP) greater than 170 mm Hg and a diastolic BP (DBP) greater than 100-130 mm Hg. Thirty patients were randomized equally into two groups: Group 1 received the drug once daily and Group 2 received it twice daily after a 2-week run-in on placebo. The study was double blind. BP was recorded 24 h (Group 1) or 12 h (Group 2) postnitrendipine. The study design permitted one dose titration if BP exceeded 170/100 mm Hg after 3 weeks of active therapy when the dose was doubled. Patients received 6 weeks of therapy at the preferred dosage. Patients underwent measurements of cerebral blood flow (CBF) initially and on three further occasions: after the final dose of placebo, and after the first and last doses of nitrendipine. With active therapy, mean SBP and DBP fell in both groups when subjects were in the sitting and standing postures, except that in Group 1 at Week 5 only, standing SBP and DBP were not significantly reduced on the 10 mg once daily regimen. At the preferred dose, eight of the 15 patients in Group 1 and 13 of the 15 patients in Group 2 responded with a reduction...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.
