Delayed tooth extraction socket (TES) healing can cause failure of subsequent oral implantation and increase socioeconomic burden on patients. Excessive amounts of M1 macrophages, apoptotic neutrophils (ANs), and neutrophil extracellular traps (NETs) impair alveolar bone regeneration during TES healing. In the present study, we first discovered that conditioned medium (CM) collected from berberine-treated human bone marrow mesenchymal stem cells (BBR-HB-CM) accelerated TES healing.

Neurite degeneration (ND) precedes cell death in many neurodegenerative diseases. However, it remains unclear how this compartmentalized cell death process is orchestrated in the central nervous system (CNS). The establishment of a CNS axotomy model (using modified 3D LUHMES cultures) allowed us to study metabolic control of ND in human midbrain-derived neurons without the use of toxicants or other direct disturbance of cellular metabolism.

Chemoprevention is one of the accessible strategies for preventing, delaying or reversing cancer processing utilizing chemical intervention of carcinogenesis. NAD(P)H quinone oxidoreductase 1 (NQO1) is a xenobiotic metabolizing cytosolic enzyme/protein with important functional properties towards oxidation stress, supporting its ability in detoxification/chemoprotective role. A set of 3,5-diylidene-4-piperidones (as curcumin mimics) bearing alkyl sulfonyl group were synthesized with potential NQO1 induction properties.

Background: Glucagon-like peptide-1 receptor agonist (GLP-1RA) therapies are increasingly used for the treatment of type 2 diabetes mellitus and obesity. Despite growing awareness of potentially increased risk of pulmonary aspiration due to delayed gastric emptying, the risks and benefits of their perioperative use in patients undergoing cardiac procedures remains unexplored. A scoping review was performed to investigate the perioperative GLP-1RA use in patients undergoing cardiac procedures and recommendations.

Repeat expansions in the fibroblast growth factor 14 gene (FGF14), associated with spinocerebellar ataxia type 27B (SCA27B), have emerged as a prevalent cause of previously unexplained late-onset cerebellar ataxia. Here, we present a patient with residual symptom of gait ataxia after complicated meningioma surgery, who presented with progressive symptoms of oculomotor disturbances, speech difficulties, vertigo and worsening of gait imbalance, twelve years post-resection. Neuroimaging revealed a surgical resection cavity in the dorsolateral side of the left cerebellar hemisphere, accompanied by gliosis in left cerebellar hemisphere extending into the vermis, extensive non-specific supratentorial periventricular white matter abnormalities, and mild atrophy of the cerebellar vermis.
