Abstract

The purpose of this study was to examine the effects of 24 wk of functional impact training (FIT) that consisted of resistance and high-impact exercises in comparison with yin yoga on body composition, bone mineral density (BMD), blood biomarkers for bone metabolism, and strength in breast cancer survivors (BCS). Forty-four BCS (60.3 ± 8.3 yr) were randomly assigned to the FIT or yin yoga group. Body composition and BMD were measured via dual energy x-ray absorptiometry. Blood biomarkers for bone metabolism were analyzed via enzyme-linked immunosorbent assays. Upper and lower body strength was assessed using a one-repetition maximum chest press and isokinetic knee extension/flexion using the Biodex System 3, respectively. Participants completed 45-min FIT or yin yoga sessions twice weekly for 24 wk. Changes in dependent variables over time were analyzed using repeated-measures ANOVA. Significance was accepted at P ≤ 0.05. There were no group-time effects for body composition, BMD, or blood biomarkers. Main effects were observed for left femoral neck (0.883 ± 0.138 to 0.870 ± 0.131 g·cm) and left forearm (0.465 ± 0.078 to 0.457 ± 0.069 g·cm) BMD. The FIT group improved upper body strength (73.2 ± 18.1 to 83.2 ± 22.3 kg), whereas...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.
