Abstract

Twenty patients with Turner syndrome (CA 7.3-16.4 years) were treated with growth hormone (GH) alone (12-18 IU/m2/week) for 0.9-2.5 years. Subsequently, all patients received GH 18 IU/m2/week in combination with oxandrolone (Ox) (0.0625 mg/kg/day po) or low dose testosterone (5 mg every 2 weeks, i.m.). Ethinylestradiol (50 ng/kg/day po) was started with a bone age of 12.5 "years", and the dose was increased stepwise to 200 ng/kg/day during the next 18 months. Final height (FH) after 4-7.7 years of therapy was 152.9 +/- 3.5 cm (range 145.0-158.9 cm). When compared to projected adult height (PAH) at start of therapy (143.7 +/- 4.0, range 137.5-151.0 cm), the estimated benefit from therapy (FH minus PAH) is 9.3 +/- 4.9 cm (range 1.4-21.4 cm). The wide range in individual responses may be due to over- or underestimation of PAH before therapy due to variable delay in bone age at start of therapy. FH did not differ between starting therapy before 11.5 years (n = 9; 152.0 +/- 3.4 cm) and after the age of 11.5 years (n = 11; 153.7 +/- 3.6 cm), due to the fact that a better short-term response to therapy in the younger group of patients was compensated for by a faster progression in bone age. The good result in terms of final height may...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.
