A.

Role of levan extracted from bacterial honey isolates in curing peptic ulcer: In vivo.

Peptic ulcer is one of the worldwide diseases where 10% of adults are affected by peptic ulcers at least once in their lifetime. The goal of this study was to evaluate the effect of levan in treating peptic ulcer. The bacterial honey isolates called Bacillus sp.

Characterization of a new efficient low molecular weight Bacillus subtilis NRC levansucrase and its levan.

Screening of 18 bacterial honey isolates revealed that all the isolates were levansucrase producers. The most potent isolate that achieved the highest activity (45.66 U/ml) was identified as Bacillus subtilis NRC based on morphological examination and 16S rRNA.

Screening of Cervical Cancer: Visual Inspection with Acetic Acid (VIA) and Site of Lesion Verified by Multiple Punch Biopsies.

Background: Cervical cancer is the tenth most frequent cancer in Egyptian women. The Papanicolaou screening test is not suitable for rural area as most follow-up consultations never take place.

Aim: To evaluate visual inspection of the cervix with acetic acid as a screening test.

New applied pharmacological approach/trend on utilization of agro-industrial wastes.

This study aimed to transform the locally available lignocellulosic residual palm frond (PF) and rice straw (RS) wastes into multifunction added products like methylated cellulose and sulfated and phosphorylated hemicelluloses by simple processes. Hydrolysis with 2 N sulfuric acid was the most suitable reaction for microcrystalline cellulose production. The characteristics of the prepared products were studied to obtain the optimum reaction conditions.

Improvement of saponin hydrolase thermal stability and productivity immobilization on a novel carrier based on sugarcane bagasse.
