Right time, right place--DNA damage and DNA replication checkpoints collectively safeguard S phase

The DNA replication checkpoint (DRC) and the DNA damage checkpoint (DDC) are two closely linked signaling cascades that adjust S phase to the presence of DNA lesions and other replication impediments. Two recent studies published in The EMBO Journal shed new light on their relationship in budding yeast, collectively showing that the two pathways—while sharing several factors—differ in the location and kinetics of their activation, suggesting that they constitute different branches of an integrated cellular response to impaired DNA replication.

CONCLUSION: The etiology of chronic groin pain post hernia repair is related in part to nerve injury. This is supported by the high frequency of sensory symptoms and numbness in these patients. However other factors including the role of tissue injury and inflammatory postoperative changes need to be considered.

Abstract Regulatory T cells (Tregs) are important for limiting inflammation-dependent damage in neural tissue. However, Tregs have also been shown to inhibit neural repair associated with type 2 (anti-inflammatory/wound healing) immune responses. Recently, it was demonstrated that Sirtuins, a family of proteins that contribute to the control of cellular responses to metabolic stimuli, influence the functions of Tregs. Specifically, SIRT4 was found to suppress the anti-neuroinflammatory activity of Tregs infiltrating the spinal cord following injury; when SIRT4 expression was genetically suppressed, Tregs made more...

Publication date: Available online 16 November 2019Source: Orthopaedics &Traumatology: Surgery &ResearchAuthor(s): Christophe Mathoulin, Mathilde GrasAbstractScapholunate ligament tear is most frequently encountered in the aftermath of trauma in supination and extension of the wrist. It generates chronic instability, leading to osteoarthritis. It may be associated with fracture of the distal epiphysis of the radius or of the scaphoid. These lesions are often difficult to diagnose, especially in early stages. Treatment of chronic scapholunate ligament lesions before onset of osteoarthritis is a challenge for the sur...

Successful closure of gastrointestinal defects is one of the most important goals for therapeutic endoscopy. Historically, surgical repair was the mainstay of treatment for any gastrointestinal defect; however, surgery is associated with high morbidity and mortality. Endoscopic management of gastrointestinal defects has developed rapidly in recent years and has become more effective, reducing the morbidity and mortality rates, and avoiding surgical interventions. Appropriate use of endoscopic techniques requires extensive knowledge of the devices and their advantages and limitations during practical applications.

The objective of this study was to test the hypothesis that comorbid type 2 immune diseases confer protection against morbidity and mortality due to acute infection. Design: Retrospective cohort study of patients hospitalized with an acute infection between November 2008 and January 2016 using electronic health record data. Setting: Single tertiary-care academic medical center. Patients: Admissions to the hospital through the emergency department with likely infection at the time of admission who may or may not have had a type 2 immune-mediated disease, defined as asthma, allergic rhinitis, atopic dermatitis, or f...

This study contributes to a better understanding of the IL-4/13A system in salmon, which as a key axis for Th2 response may be involved not only in pathogen elimination but also in adaptive immune repair that seems critical tolerance to infectious diseases.
