Purpose: To evaluate the suitability of Nanoskin, a biomaterial derived from bacterial cellulose, as an alternate material for repairing the posterior lamellae of the eyelids.
Methods: Forty guinea pigs received a fragment of Nanoskin subcutaneously in the dorsal region. The animals received Nanoskin (group 1) or Nanoskin coated with a gelatin layer (group 2). The animals were observed daily for over 7, 30, 90, or 180 days with the subcutaneous implants in place. The animals were euthanized at a designated time and the Nanoskin was removed for histologic, morphometric, and transmission electron microscopy evaluation.
Results: The results were similar for both groups. The subcutaneously implanted Nanoskin resulted in good tissue integration, induced mild inflammation, and was surrounded by a delicate pseudocapsule.
Conclusion: The good tissue integration of Nanoskin in study indicates that it may be a potential material for application as a substitute of posterior eyelid lamellar tissue. Further clinical studies are required to confirm the preliminary outcomes of this experimental study.

This study investigates the gross morphological and morphometric characteristics of thoracic and lumbar intervertebral discs (IVDs) in guinea pigs, utilising micro-CT imaging and anatomical dissection. The findings reveal 13 thoracic and six lumbar IVDs were identified, with thoracic discs transitioning from rounded forms at T1-T3 to triangular and heart-shaped structures at T4-T13, while lumbar IVDs exhibited a consistently flattened heart shape. Morphometric analysis revealed statistically significant differences, with lumbar IVDs being larger in lateral and dorsoventral width, disc area, annulus fibrosus (AF) area and nucleus pulposus (NP) area, and ventral height compared to thoracic discs.

Neurosteroid replacement therapy using tiagabine and zuranolone restores cerebellar neurodevelopment and reduces hyperactive behaviour following preterm birth.

Preterm birth exposes the neonate to hypoxic-ischaemic and excitotoxic insults that impair neurodevelopment and are magnified by the premature loss of placentally supplied, inhibitory neurosteroids. The cerebellum is a neuronally dense brain region, which undergoes critical periods of development during late gestation, when preterm births frequently occur. We propose that neurosteroid replacement therapy using tiagabine and zuranolone will protect the cerebellum against preterm-associated insults.

The research conducted in this preclinical study assesses QazCovid-live, a live attenuated COVID-19 vaccine created in Kazakhstan, by conducting preclinical evaluations of safety, immunogenicity, and allergenicity in various animal models, including mice, rats, hamsters, and guinea pigs. The vaccine, developed by attenuating SARS-CoV-2 via numerous Vero cell passages, had no significant adverse effects in acute and subacute toxicity assessments, even at elevated dosages. Allergenicity testing indicated the absence of both immediate and delayed hypersensitivity reactions.
