Radiofrequency ablation: mechanisms and clinical applications.

Radiofrequency ablation (RFA), a form of thermal ablation, employs localized heat to induce protein denaturation in tissue cells, resulting in cell death. It has emerged as a viable treatment option for patients who are ineligible for surgery in various diseases, particularly liver cancer and other tumor-related conditions. In addition to directly eliminating tumor cells, RFA also induces alterations in the infiltrating cells within the tumor microenvironment (TME), which can significantly impact treatment outcomes.

Music emotion recognition based on temporal convolutional attention network using EEG.

Music is one of the primary ways to evoke human emotions. However, the feeling of music is subjective, making it difficult to determine which emotions music triggers in a given individual. In order to correctly identify emotional problems caused by different types of music, we first created an electroencephalogram (EEG) data set stimulated by four different types of music (fear, happiness, calm, and sadness).

Exosomes Derived by SIRT1-Overexpressing Bone Marrow Mesenchymal Stem Cells Improve Pubococcygeus Muscle Injury in Rats.

Background And Objectives: To evaluate the effect of exosomes (Exos) derived from silent mating type information regulation 2 homolog 1 (SIRT1)-overexpressing human bone marrow mesenchymal stem cells (BMSCs) on the recovery of pubococcygeus muscle Injury.

Methods And Results: Exos isolated from SIRT1-overexpressing BMSCs (SIRT1/exos) were injected into a vaginal dilation-induced rat model of Stress urinary incontinence (SUI). The efficacy of Exos treatment on SUI was evaluated by determining the values of urodynamic parameters.

Spatial-seasonal variation of soil denitrification under three riparian vegetation types around the Dianchi Lake in Yunnan, China.

Outbreaks of nuisance cyanobacterial bloom are predicted to occur frequently under the effect of severe eutrophication in the water body of Lake Dianchi since the 1990s. Riparian buffers are now well recognized for their roles in the removal of inorganic nitrogen mainly via denitrification. Little is known, however, about the mechanisms of nitrate removal in the riparian buffers of Lake Dianchi.
