S-2 (3-aminopropylamino)ethylphosphorothioate ameliorates hearing losses due to ototoxic doses of kanamycin sulfate in the guinea pig when administered one hour before the antibiotic. Since this radioprotectant is believed to operate as a free-radical scavenger, kanamycin ototoxicity may involve free radicals.

genetic transformation studies were carried out to standardize a protocol for agrobacterium -mediated genetic transformation of three economically important strawberry (fragaria x ananassa duch) cultivars kurdistan’, camarosa’, and ‘paros’. shoot regeneration frequency 72, 65 and 30% was obtained on ms (1) basal medium supplemented with 2% glucose and 4 mg/l tdz for camarosa, kurdistan and paro...

(Fig. 1).3) Butirosin (Fig. 2) has the L-HABA structure as an acylated side chain on its 2-deoxystreptamine molecule. The structural analogies between AMK and BTR suggest that AMK could be formed by feeding KMA to a broth culture of B. circulars. Recent reports on the biosynthesis of BTR4•5) indicate that the coupling of L-HABA to the ribostamycin (RBT) molecule (Fig. 2) could be one of the las...

Aim of the present study was to assess changes in microflora delayed and immediately placed implant. In this study, a total 30 implant areas patients were analyzed. The group consists 14 male 16 female participants age range 20-40 years. randomly divided into two groups (15 each group). Group A: Immediate Implant Placement, B: Delayed Placement. placement done accordingly. materials media used ...
