Apoptosis repressor with caspase recruitment domain (ARC) is a potent inhibitor of apoptosis. Under physiological conditions, ARC is abundantly expressed in terminally differentiated cells, including cardiomyocytes, skeletal muscles and neurons. ARC serves a key role in determining cell fate, and abnormal ARC expression has been demonstrated to be associated with abnormal cell growth. Previous studies have revealed that ARC was upregulated in several different types of solid tumor, where it suppressed tumor cell apoptosis. Furthermore, the increased expression levels of ARC in cancer cells contributed to the development of therapeutic resistance and adverse clinical outcomes in patients with leukemia. However, the exact role of ARC, as well as the underlying molecular mechanisms involved, remain poorly understood. The present review summarizes the characteristics of ARC and its cytoprotective role under different conditions and describes the potential ARC as a new target for cancer therapy.

Treatment of anterior rim fractures of the distal radius with an anterior rim plate: A retrospective study.

Department of Orthopedics, E-Da Hospital, I-Shou University/School of Medicine, College of Medicine, I-Shou University, Kaohsiung, Taiwan.
Treatment of distal radial fractures that include small anterior rim fragments can be difficult. We retrospectively reviewed 19 patients in whom an anterior rim plate with locking screws was used. After a median follow-up of 18 months (range 6-32; interquartile range (IQR) 14, 26), the median wrist flexion and extension arc was 70° (range 50-80; IQR 60, 70), the median grip strength was 80% of the contralateral side (range 52-104; IQR 77, 88), the median visual analogue scale score for pain was 0 (range 0-5; IQR 0, 1), the median disabilities of the arm, shoulder and hand score was 2 (range 0-59; IQR 0, 11) and the median modified Mayo wrist score was 80 (range 35-100; IQR 75, 85).

Background: Research is needed to improve the performance of primary health care. In Africa, few family physicians conduct research, and therefore an online research training and mentorship programme was developed to build research capacity amongst novice and early career researchers.
Aim: To evaluate the implementation of the AfriWon Research Collaborative (ARC) training and e-mentorship programme in sub-Saharan Africa.
Surgical Outcomes of Lateral Ulnar Collateral Ligament Reconstruction Versus Repair for Posterolateral Rotatory Instability of the Elbow: A Systematic Review and Meta-analysis.
Orthop J Sports Med
January 2025
Department of Orthopaedic Surgery, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea.
Background: The aim of surgical treatment for posterolateral rotatory instability (PLRI) of the elbow is to restore the integrity of the lateral ulnar collateral ligament (LUCL), with ligamentous reconstruction being the preferred option for recurrent symptomatic PLRI. However, there is no clinical evidence demonstrating the superiority of reconstruction versus repair. Treatment options currently depend on the cause of the LUCL injury and surgeon preference.

In processes such as electrodialysis, the applied electrical potential is constrained by concentration polarization at the membrane/solution interface. This polarization, which intensifies at higher current densities, impedes ion transport efficiency and may lead to problems such as salt precipitation, membrane degradation, and increased energy consumption. Therefore, understanding concentration polarization is essential for enhancing membrane performance, improving efficiency, and reducing operational costs.

Human-driven habitat loss is recognized as the greatest cause of the biodiversity crisis, yet to date we lack robust, spatially explicit metrics quantifying the impacts of anthropogenic changes in habitat extent on species' extinctions. Existing metrics either fail to consider species identity or focus solely on recent habitat losses. The persistence score approach developed by Durán .
