The novel antiepileptic drug levetiracetam (keppra, 80 mg/kg, i.p.) produces a pronounced anticonvulsant effect on all parameters of the audiogenic locomotion response in Wistar rats, leading to the prevention of acoustic seizures approximately in 50% animals. Keppra injection also led to a decrease in the intensity of single audiogenic convulsive episode, a twofold prolongation of the latency of motor reaction, and a change in the pattern of seizure reaction toward increasing number of rats with "one-wave" response. In contrast, a lack of sound resistant animals and the change from one- to two-wave audiogenic response were observed in Krushinsky-Molodkina strain rats.

Formulation Design, Optimization, and Evaluation of Solid Lipid Nanoparticles Loaded With an Antiviral Drug Tenofovir Using Box-Behnken Design for Boosting Oral Bioavailability.

The current study aimed to improve the oral bioavailability of tenofovir (TNF), an antihuman immunodeficiency viral (HIV) drug, by integrating it into solid lipid nanoparticles (SLNs), an emerging lipid formulation. The suggested SLNs were generated utilizing the microemulsion process, using Compritol 888 ATO. A Box-Behnken experimental design was attempted to analyze the impact of critical quality attributes (CQAs), such as lipid and surfactant content and homogenization duration on response metrics such as particle size (PS) and percentage entrapment.

Objectives: To investigate in vivo whether myofibroblasts formed in the PDL after exposure to short-term high experimental orthodontic forces in rats survive. To study in vitro whether human PDL fibroblasts can differentiate into myofibroblasts and survive when chemical or mechanical stimuli are removed.
Design: Nine 6-week-old male Wistar rats were used in this experiment.

Objective: To observe the effects of (transforming stasis and unblocking collaterals) moxibustion on learning-memory ability and hippocampal mammalian sterile 20-like kinase 1 (Mst1)/nuclear factor κB (NF-κB) p65 pathway related to inflammatory response in rats with vascular dementia (VD).
Methods: A total of 60 male Wistar rats of SPF grade were randomly divided into a sham operation group (12 rats) and a modeling group (48 rats). VD model was established by the method of modified bilateral common carotid artery permanent ligation in the modeling group.

Empagliflozin (EMPA) is one of the sodium/glucose cotransporter 2 (SGLT2) inhibitors that has been recently approved for the treatment of diabetes mellitus type II. Recently, EMPA has shown protective effects in different neurological disorders, besides its antidiabetic activity. Kindling is a relevant model to study epilepsy and neuroplasticity.

Purpose: To evaluate the peritoneal histopathological changes and culture after the use of intravenous meropenem and intra-abdominal inoculation of 10% aqueous extract of anacardiaceae, in elderly rat model after autogenous fecal peritonitis induced.
Methods: Thirty 18-month-old Wistar rats received induction of autogenous fecal peritonitis and then were stratified into two groups: study I, treated with meropenem (40 mg/kg); and study II, treated with meropenem (40 mg/kg) and intraperitoneal 10% aqueous extract of anacardiaceae. Animals were monitored for 15 days until euthanasia.
