Biological interaction of bioactive polymeric membranes in induced bone defects in rabbit tibias.

The study aimed to evaluate bone repair using three osteoinductive polymers in bone defects created in rabbit tibias. Forty-eight adult rabbits were assessed at various time points: three, seven, fourteen, and thirty days. The groups included a control group (without biomaterial), M1 (Poly L Lactide co Polycaprolactone/Polyethylene Glycol), M2 (Poly L Lactide co Polycaprolactone/Polyethylene Glycol/β-Tricalcium Phosphate), and M3 (Poly L Lactide co Polycaprolactone/Polyethylene Glycol/nano hydroxyapatite).

Does Ovariectomy Affect the Mechanics of the Mandibular Alveolar Bone Structure of Wistar Rats Subjected to Tooth Loss and Modified Diet?-A FEA Study.

The aim of this study was to evaluate the mechanical effect of ovariectomy, diet, and tooth extraction on the bone structure of the mandible of Wistar rats. Mandibles from 40 female Wistar rats were used, divided into rats with ovariectomy surgery or surgical simulation. Half of the rats had the right upper incisor extracted and a soft diet was introduced for half of the animals for 30 days.

ReflACTION framework: A proposed model for implementation of clinical pharmacy services.

The implementation of clinical pharmacy services (CPS) has grown worldwide. However, few studies have used models and/or frameworks to facilitate the implementation process, especially in a low and middle-income countries. In addition, there are limitations in the ways that implementation frameworks are used.

Esophageal achalasia: A case report in an adolescent.

Esophageal achalasia is an uncommon disease in pediatrics. With an insidious clinical presentation, diagnosis is delayed. Here we describe a case of esophageal achalasia in a 16-year-old girl, with the typical delay in consultation and diagnosis.

Quantitative Analysis of Glutathione and Carnosine Adducts with 4-Hydroxy-2-nonenal in Muscle in a hSOD1 ALS Rat Model.

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by the dysfunction and death of motor neurons through multifactorial mechanisms that remain unclear. ALS has been recognized as a multisystemic disease, and the potential role of skeletal muscle in disease progression has been investigated. Reactive aldehydes formed as secondary lipid peroxidation products in the redox processes react with biomolecules, such as DNA, proteins, and amino acids, resulting in cytotoxic effects.
