Purpose: overexpression/amplification in wild-type (WT) metastatic colorectal cancer (mCRC; human epidermal growth factor receptor 2 [HER2]-positive mCRC) appears to be associated with limited benefit from anti-EGFR antibodies and promising responses to dual-HER2 inhibition; however, comparative efficacy has not been investigated. We conducted a randomized phase II trial to evaluate efficacy and safety of dual-HER2 inhibition against standard-of-care anti-EGFR antibody-based therapy as second/third-line treatment in HER2-positive mCRC.

Methods: Patients with -WT mCRC after central confirmation of HER2 positivity (immunohistochemistry 3+ or 2+ and in situ hybridization amplified [HER2/CEP17 ratio >2.

The physiological and clinical importance of motile cilia in reproduction is well recognized, however, the specific role they play in transport through the oviduct and how ciliopathies lead to subfertility and infertility is still unclear. The contribution of cilia beating, fluid flow, and smooth muscle contraction to overall progressive transport within the oviduct remains under debate. Therefore, we investigated the role of cilia in the oviduct transport of preimplantation eggs and embryos using a combination of genetic and advanced imaging approaches.

Article Synopsis
  • The study investigates how high glucose levels in diabetes lead to kidney cell damage through the activation of a signaling pathway involving DJ-1 and PTEN.
  • DJ-1 is found to be upregulated in kidney cells under high glucose conditions, which triggers the Akt/mTORC1 signaling pathway, resulting in cell growth and fibrosis.
  • The research indicates that inhibiting DJ-1 can prevent glucose-induced cell growth and damage, while overexpressing DJ-1 replicates the harmful effects, highlighting its role in renal injury related to diabetes.

Article Synopsis
  • A new method for C-H functionalization of heteroaryl compounds is introduced, which involves a process called dearomative addition followed by hydrogen autotransfer.
  • This process starts with the hydroruthenation of dienes to create allylruthenium nucleophiles, leading to branched C-C coupling products through addition and β-hydride elimination.
  • The study also details the formation of enantiomerically enriched heteroarylethyl alcohols and amines through oxidative cleavage and dynamic kinetic asymmetric reduction, supported by density functional theory calculations linking regioselectivities to molecular factors.

The error-related negativity (ERN) has been called a putative neural marker of anxiety risk in children, with smaller ERN amplitudes denoting greater risk in early childhood. Children of anxious mothers are at elevated risk for anxiety problems compared to children of non-anxious mothers. Still unknown is whether discrete maternal symptoms interact with child ERN to predict different forms of child anxiety risk, knowledge of which could increase our understanding of the specificity of known conditions and pathways for transgenerational effects.
