Point-of-Care Diagnosis of Tuberculosis Using a Portable Nucleic Acid Test with Distance-Based Readout.

Rapid and accurate diagnosis of tuberculosis (TB) infection in resource-limited settings is critically needed to stop the spread of the disease but remains difficult to achieve. Herein, we report a fast, inexpensive nucleic acid test with distance-based readout (FINDR) for TB. Based on the unique chromatographic behavior of DNA intercalating dye on unmodified cellulose paper, our FINDR platform converted the amplicons of loop-mediated isothermal amplification (LAMP) into the migration distance on a paper-based analytical device.

Downregulation of salusins alleviates hypertrophic cardiomyopathy via attenuating oxidative stress and autophagy.

Introduction: Salusins, which are translated from the alternatively spliced mRNA of torsin family 2 member A (TOR2A), play a vital role in regulation of various cardiovascular diseases. However, it remains unclear precisely regarding their roles in hypertrophic cardiomyopathy (HCM). Therefore, this study was conducted to explore therapeutic effect and the underlying mechanisms of salusins on HCM.

Icariin-loaded 3D-printed porous Ti6Al4V reconstruction rods for the treatment of necrotic femoral heads.

Avascular necrosis of the femoral head is a prevalent hip joint disease. Due to the damage and destruction of the blood supply of the femoral head, the ischemic necrosis of bone cells and bone marrow leads to the structural changes and the collapse of the femoral head. In this study, an icariin-loaded 3D-printed porous Ti6Al4V reconstruction rod (referred to as reconstruction rod) was prepared by 3D printing technology.

New insights into the role of long non-coding RNAs in osteoporosis.

Osteoporosis is a common disease in elderly individuals, and osteoporosis can easily lead to bone and hip fractures that seriously endanger the health of elderly individuals. At present, the treatment of osteoporosis is mainly anti-osteoporosis drugs, but there are side effects associated with anti-osteoporosis drugs. Therefore, it is very important to develop early diagnostic indicators and new therapeutic drugs for the prevention and treatment of osteoporosis.
