Bax is a pro-apoptotic member of the Bcl-2 family proteins involved in the release of apoptogenic factors from mitochondria to the cytosol. Recently, it has been shown both in mammals and yeast that Bax insertion in the mitochondrial outer membrane involves at least two distinct mechanisms, one of which uses the TOM complex. Here, we show that in Drosophila, heterozygous loss of function mutations of Tom22 or Tom70, two receptors of the TOM complex, attenuates bax-induced phenotypes in vivo. These results argue that the TOM complex may be used as a mitochondrial Bax receptor in Drosophila.

Late Talkers' Language, Metaphor, Theory of Mind, and Reading Skills at 9 Years of Age.
J Speech Lang Hear Res

Research Unit of Language and Communication, Department of Rehabilitation Sciences, TU Dortmund University, Germany.
Purpose: Prior work has found that "late talkers" (LTs) as a group continue to demonstrate lower language and reading outcomes compared to their typically developing (TD) peers even into young adulthood. Others identified that children diagnosed with developmental language disorder (DLD) show difficulties later with theory of mind (ToM) tasks and metaphor comprehension, but there is a shortage of research specifically investigating these advanced skills in LTs. The current study therefore compared language-related skills of former LTs with their TD peers at school age.

Objectives: Trans and/or gender diverse (T/GD) people in the UK are less likely to access sexual health services (SHS) than cisgender people and are more likely to report negative experiences. The British Association for Sexual Health and HIV (BASHH) developed expert recommendations for T/GD-inclusive SHS, but these lack service user perspectives. This study addressed this gap by asking T/GD people how SHS could be T/GD-inclusive.

Artificial intelligence and robotics are transforming interventional radiology, driven by advancements in computer vision, robotics and procedural automation. Historically focused on diagnostics, AI now also enhances procedural capabilities in IR, enabling future robotic systems to handle complex tasks such as catheter manipulation or needle placement with increasing precision and reliability. Early robotic systems in IR demonstrated improved accuracy in both vascular and percutaneous interventions, though none were equipped with automatic decision-making.

Background: To investigate the role of the translocase of the outer mitochondrial membrane 40 (TOM40) in oral squamous cell carcinoma (OSCC) with the aim of identifying new biomarkers or potential therapeutic targets.
Methods: TOM40 expression level in OSCC was evaluated using datasets downloaded from The Cancer Genome Atlas (TCGA), as well as clinical data. The correlation between TOM40 expression level and the clinicopathological parameters and survival were analyzed in TCGA.
