Germline pathogenic variants in HIC1 DNA binding domains are associated with familial serrated polyposis syndrome

International Journal of Cancer, EarlyView.
What's New? Serrated polyposis syndrome has been associated with an increased risk of colorectal cancer. HIC1 is a tumor suppressor gene commonly silenced in serrated polyps and several cancers. This study suggests HIC1 as a novel germline predisposition factor to serrated polyposis syndrome, with variants altering gene transcriptional regulation and ...

Disrupting the Chain of Displaced Aggression: A Review and Agenda for Future Research

Journal of Organizational Behavior, EarlyView.
ABSTRACT Displaced aggression refers to instances in which a person redirects their harm‐doing behavior from a primary to a secondary, substitute target. Since the publication of the first empirical article in 1948, there has been a noticeable surge in research referencing this theory in both management and psychology journals.

The Influence of Atmospheric Overvoltages on High-Voltage SF6 Substations [PDF]

, 2011
Very fast overvoltages are characteristic of high-voltage metal-enclosed SF6 insulated substations. During the transient phenomenon, on the SF6 substation enclosure an undesired, short-lasting induced overvoltage may appear, which cannot be prevented ...

AO/AAP consensus on prevention and management of peri‐implant diseases and conditions: Summary report

Journal of Periodontology, EarlyView.
Abstract Background The exponential increase in dental implant use has led to a parallel rise in peri‐implant diseases (PID), adversely affecting implant therapy success and patient quality of life. Efforts have been made by the dental community to understand systemic, behavioral, and site‐level risk factors involved in the etiologies and pathogenesis ...

A comprehensive review on adaptive plasticity and recovery mechanisms post‐acquired brain injury

Neuroprotection, EarlyView.
This figure illustrates the dynamic process of neurogenesis following brain injury, focusing on the roles of neural stem and progenitor cells at the injury site. Key mechanisms include axonal sprouting, synaptogenesis, dendritic remodeling, and brain‐derived neurotrophic factor signaling via TrkB receptors.
