New proposal for the treatment of coronal split fractures in lumbar vertebrae: the fatigue curve

Coluna/Columna; 20 (2), 2021
ABSTRACT Objective: To evaluate a new treatment for split fractures through fatigue tests on a swine model. Methods: Thirty lumbar spine samples (L2-L3-L4) from swine models were divided into three test groups. The first was the control group (intact vertebrae). In the second group, a bone defect was c...

The Effects of 2100 MHz Radio Frequency Radiation on Thyroid Tissues

West Indian med. j; 69 (1), 2021
ABSTRACT Objective: To reveal the effect of 2100 MHz radio frequency (RF) radiation on thyroid tissues of rats in the 10 days (group E1) and 40 days (group G1) exposure groups. Methods: In this study, 30 healthy female Wistar albino rats, weighing 200−256 g each, were used. The animals were rando...

Pain-related toxins in scorpion and spider venoms: a face to face with ion channels

Pain is a common symptom induced during envenomation by spiders and scorpions. Toxins isolated from their venom have become essential tools for studying the functioning and physiopathological role of ion channels, as they modulate their activity. In particular, toxins that induce pain relief effects can ...

Gold nanoparticles as a promising treatment for diabetes and its complications: Current and future potentials

Diabetes and its complications represent a major cause of morbidity and mortality in diabetes patients. This review is aimed to find the potential of gold nanoparticles (AuNPs) to act as therapeutic agents for diabetes and its complications. Here, we outline the literature related to the self-therapeutic...
