Impact of repeated intranasal gentamicin irrigation on auditory brainstem evoked potentials in rats.

Gentamicin is a bactericidal aminoglycoside antibiotic that broadly targets Gram-negative microbes. Both human and animal studies have shown that administration of gentamicin is ototoxic by several routes of administration and results in sensorineural hearing loss due to damaged hair cell at the base of the cochlea. However, gentamicin is also administered intranasally to treat sinusitis in humans, but no animal studies have examined ototoxicity of gentamicin administered via this route.

Chemical characterization, neuroprotective effect, and evaluation of the petroleum ether extract of three palm tree species against glutamate-induced excitotoxicity in rats.

The burden of neurological disorders is growing substantially with limited therapeutic options, urging the consideration and assessment of alternative strategies. In this regard, we aimed to elucidate the phytochemical profile of the petroleum ether extract (PEE) of three palm tree species: Burret, H. Wendl.

Successful Vascular Graft Reconstruction of Short Renal Artery Using Polytetrafluoroethylene (PTFE) in Living Donor Kidney Transplantation-A Case Report and Review of Literature.

Short donor renal artery during nephrectomy poses a technical challenge. We present a main renal artery (RA) reconstruction case in Living-donor kidney transplantation (LDKT) using an extension polytetrafluoroethylene vascular graft(PTFE). A 57-year-old man received LDKT from his son.

Novel pyrimidine derivatives and black cumin as xanthine oxidase inhibitors: Synthesis, docking study and formulation.

In this work, to attempt discovery of novel xanthine oxidase (XO) inhibitors, we developed a method for optimizing the Nigella sativa oil extraction by considering the seed size particles, the liquid seed ratio, the duration of the extraction procedure and the temperature of extraction. On the other hand, new pyrimidine and triazolopyrimidine derivatives were prepared in an attempt to mimic the pyrazolpyrimidine structure of allopurinol (a well-known xanthine oxidase inhibitor drug). Most of the developed compounds were shown to have strong xanthine oxidase inhibitory activities, while Nigella sative extract and compound 6b ranked as the most effective inhibitors (IC=1.

Obliteration of a glycinergic projection to the medial geniculate in an animal model of autism.

Auditory dysfunction affects the vast majority of people with autism spectrum disorder (ASD) and can range from deafness to hypersensitivity. exposure to the antiepileptic valproic acid (VPA) is associated with significant risk of an ASD diagnosis in humans and timed exposure to VPA is utilized as an animal model of ASD. VPA-exposed rats have significantly fewer neurons in their auditory brainstem, thalamus and cortex, reduced ascending projections to the midbrain and thalamus and reduced descending projections from the cortex to the auditory midbrain.
