Prostaglandin E and Akt promote stemness in Apc mutant Dclk1+ cells to give rise to colitis-associated cancer.

Background And Aims: Loss of the tumor suppressor gene Apc in Lgr5+ intestinal stem cells results in aberrant Wnt signaling and colonic tumorigenesis. In the setting of injury, however, we and others have also shown that non-stem cells can also give rise to colonic tumors. The mechanism by which inflammation leads to cellular plasticity and cancer, however, remains largely unknown.

A review of clinical applications of pharmacokinetic simulations for a 2-month long-acting injectable formulation of aripiprazole.

Aripiprazole 2-month ready-to-use (Ari 2MRTU) is a long-acting injectable antipsychotic that was approved for use in Europe in March 2024, for the maintenance treatment of schizophrenia in adult patients stabilized with aripiprazole; it is administered via gluteal intramuscular injection once every two months. This review examines population pharmacokinetic model-based simulations relevant to the use of Ari 2MRTU in Europe, accompanied by expert commentary that contextualizes the simulations and highlights the potential implications of the availability of Ari 2MRTU for patients, caregivers, and clinicians. Various simulations conducted across 8 weeks (representing the first dosing interval), or 32 weeks (representing maintenance dosing) demonstrated an aripiprazole exposure profile for Ari 2MRTU that was similar to aripiprazole once-monthly (AOM), but with an extended dosing interval.

Perceived stress across population segments characterized by differing stressor profiles-A latent class analysis.

Objective: We aimed to 1) identify distinct segments within the general population characterized by various combinations of stressors (stressor profiles) and to 2) examine the socio-demographic composition of these segments and their associations with perceived stress levels.

Methods: Segmentation was carried out by latent class analysis of nine self-reported stressors in a representative sample of Danish adults (N = 32,417) aged 16+ years. Perceived stress level was measured by the Perceived Stress Scale (PSS).

Field vaccination of locally-owned cattle against malignant catarrhal fever under environmentally challenging conditions in Tanzania.

Malignant catarrhal fever (MCF), caused by alcelaphine herpesvirus-1 (AIHV-1) transmitted from wildebeest, is a lethal cattle disease with significant impacts on East African pastoralists. Development of a live attenuated MCF vaccine has prompted research into its use in communities at risk. This study reports results from the first utilisation of the MCF vaccine in locally-owned cattle under field conditions.

Characterization of human melanoma skin cancer models: A step towards model-based melanoma research.

Advancing 3D in vitro human tissue models is crucial for biomedical research and drug development to address the ethical and biological limitations of animal testing. Recently, 3D skin models have proven to be effective for studying serious skin conditions, such as melanoma. For these advanced models to be applicable in preclinical studies, thorough characterization is essential to understand their applicability and limitations.
