Mesoporous Lanthanum-Doped Magnesium Phosphate Nanopowders Promote Healing of Critical-Size Bone Defects: An In Vivo Study.

Treating severe bone deformities and abnormalities continues to be a major clinical hurdle, necessitating the adoption of suitable materials that can actively stimulate bone regeneration. Magnesium phosphate (MP) is a material that has the ability to stimulate the growth of bones. The current study involved the synthesis of mesoporous MP and lanthanum (La)-doped nanopowders using a chemical precipitation approach.

Ramadan diurnal intermittent fasting in patients with diabetes: assessment of knowledge, practices, risk of complications, and impact of pre-ramadan education.

Objectives: Evaluate diabetic patients' knowledge, practices, and the prevalence of complications during Ramadan fasting (RF) before and after an education program.

Methods: We conducted a prospective study including 140 consecutive diabetic patients (DP) who intended to observe RF in 2023. Patients underwent a questionnaire and received pre-Ramadan education (PRE) according to the IDF-DAR 2021 recommendations.

The link between BDNF and platelets in neurological disorders.

Platelets are considered one of the most important reservoirs not only of growth factors, but also of neurotrophic factors that could contribute to the repair of vascular lesions and the prevention of neurological deterioration. Among these factors, Brain-Derived Neurotrophic Factor (BDNF) - a protein belonging to the neurotrophin family - is widely expressed both in the hippocampus and in platelets. Platelets constitute an important reservoir of BDNF; however, little is known about the factors modulating its release into the circulation and whether anti-platelet drugs affect this secretion.

Group cohesion and passive dynamics of a pair of inertial swimmers with three-dimensional hydrodynamic interactions.

When swimming animals form cohesive groups, they can reap several benefits. Our understanding of collective animal motion has traditionally been driven by models based on phenomenological behavioral rules, but more recent work has highlighted the critical importance of hydrodynamic interactions among a group of inertial swimmers. To study how hydrodynamic interactions affect group cohesion, we develop a three-dimensional, inviscid, far-field model of a swimmer.
