Reconstruction of craniomaxillofacial defects is a challenge for surgeons and has psychological and functional burdens for patients. Undoubtedly, there is a need for improved biomaterials and techniques for craniomaxillofacial reconstruction. We assessed the potential regeneration of bone using three modifications of a novel composite and explored the validity of a new measurement using microcomputed tomography (micro-CT). We placed three different composite samples in calvarial defects in rats and analysed healing with micro-CT. The results showed that polycaprolactone (PCL) with phosphate glass fibre is promising for non-load bearing applications in the craniomaxillofacial region. Also, the new micro-CT measurement of the temporal characterisation of the mineralisation of bone (TCBM) has the potential to evolve into a reliable predictor of bony healing and its quality.

Unlabelled: Nonalcoholic fatty liver disease (NAFLD) is a rising global health problem. The antidiabetic canagliflozin (CANA) has been proposed to ameliorate the metabolic abnormalities in NAFLD.
Aim: This study aimed to explore the possible anti-NAFLD effects of CANA in rats and HepG2 cells, focusing on AMPK/SIRT1-mediated lipophagy.

Autism spectrum disorder (ASD) is marked by neurobehavioral developmental deficits, potentially linked to disrupted neuron-glia interactions. The astroglia Kir4.1 channel plays a vital role in regulating potassium levels during neuronal activation, and mutations in this channel have been associated with ASD.

Poly (lactic-co-glycolic acid) (PLGA) is an important biomaterial for tissue defect repair, but its application in replacing missing brain tissue needs improvement. Mesenchymal stem cells (MSCs) have been used to treat various neurological diseases, but they face challenges when filling large tissue defects. The purpose of this study was to investigate the effects of PLGA combined with MSCs transplantation on brain structure and neural function in rats with traumatic brain injury (TBI), and explore its possible mechanism.

Cisplatin is a widely used chemotherapeutic agent, but its clinical utility is limited by side effects affecting different systems and organs, including hepatotoxicity in some cases. Baicalin, a flavonoid isolated from Scutellaria baicalensis, possesses antioxidant, anti-inflammatory and hepatoprotective properties, but its low bioavailability limits its therapeutic use. This study aimed to investigate whether a nanoemulsion formulation of baicalin could enhance its efficacy against cisplatin-induced hepatic injury in rats.

Aging women experience a significant decline of ovarian hormones, particularly estrogen, following menopause, and become susceptible to cognitive and psychomotor deficits. Although the effects of estrogen depletion had been documented in the prefrontal and somatosensory cortices, its impact on somatomotor cortex, a region crucial for motor and cognitive functions, remains unclear. To explore this, we ovariectomized young adult female rats and fed subsequently with phytoestrogen-free diet and studied the effects of estrogen depletion on the somato-sensory and motor cortices.
