Crypt density and recruited enhancers underlie intestinal tumour initiation.

Oncogenic mutations that drive colorectal cancer can be present in healthy intestines for long periods without overt consequence. Mutation of Adenomatous polyposis coli (Apc), the most common initiating event in conventional adenomas, activates Wnt signalling, hence conferring fitness on mutant intestinal stem cells (ISCs). Apc mutations may occur in ISCs that arose by routine self-renewal or by dedifferentiation of their progeny.

Social Disengagement in Post-Pandemic China: A Translation, Validation and Cross-Cultural Comparison of the Pandemic Disengagement Syndrome Scale.

Background: In contrast to abundant research on the various acute mental effects of COVID-19, the long-term influences of the pandemic are still underexplored in China owing to the paucity of assessment tools. The Pandemic Disengagement Syndrome Scale (PDSS) assesses people's social disengagement as a lasting psychological consequence in Western countries during the post-COVID-19 pandemic era. However, its generalizability across cultures is untested.

Piezosurgery in Third Molar Extractions: A Systematic Review.

: The aim of this systematic review was to evaluate the clinical efficacy, benefits, and limitations of piezosurgery in tooth extractions compared to conventional methods. Piezosurgery has emerged as a minimally invasive alternative, promoting better preservation of soft tissues and bone structures. Understanding its impact on postoperative outcomes such as pain, swelling, trismus, and bone healing is critical for its application in oral surgery; We restricted our search to English-language articles published between 1 January 2004 and 28 August 2024, in PubMed, Scopus, and Web of Science.

Topical insulin used alone or in combination with drug-depository contact lens for refractory cases of neurotrophic keratopathy.

Purpose: To report the clinical outcomes achieved in refractory cases of neurotrophic keratopathy (NK) through the utilization of insulin eye drops alone or in conjunction with a drug-depository contact lens (DDCL).

Observations: This multicentric prospective open-label uncontrolled case series included consecutive patients with NK refractory to conventional treatment. Insulin eye drops (1 unit/mL) were prescribed 4 times/day in all cases, and a Therapeutic Hyper-CL™ soft contact lens (EyeYon Medical, Ness Ziona, Israel), designed to act as a drug reservoir, was applied in selected patients.

Effectiveness and Personalized Approaches in the Correction of Gummy Smile: A Systematic Review of Orthodontic and Surgical Treatments.

This systematic review seeks to assess the effectiveness of different orthodontic and combined orthodontic-surgical approaches for correcting gummy smile, with a focus on treatment efficacy, duration, and the potential for integrating various techniques. The objective is to offer evidence-based recommendations for the optimal management of gummy smile. A thorough search of the literature was conducted in the PubMed, Cochrane Library, Scopus, and Web of Science databases, covering publications from 1 January 1982 to 4 November 2024.
