Abstract:Background: Aquaculture have developed more and more strongly in many countries around the world. However, a intensive shrimp or fish farming model always have issues in pond water pollution. NH3 and NO2 toxic gases are two direct threats to survival rate and growth of aquatic animals. It is necessary to find out a economical and environmentally friendly solution in order to control NH3 and NO2 in aquaculture ponds. Therefore, this study was carried out to get an effective approach based on the combination of Bacillus sp. and Yucca schidigera extract in NH3 and NO2 control. Materials and Methods: Bacillus sp. is isolated on NA medium from sludge samples collected in Can Gio Mangrove Forest. Screening Bacillus strains and dilution......

Abstract: After sprouting of onions, the shoots are used as vegetables and bulbs discarded. These usually discarded onion bulbs may have improved antioxidant potentials resulting from sprouting. These improved properties could be harnessed to combat or manage some degenerative and non-communicable diseases. This study was therefore conducted to determine the effects of sprouting and boiling on the antioxidant potentials of onions (Allium cepa L.). Samples were either sprouted for 0 – 10 days or boiled for 0 – 8 minutes. Phytochemical (total phenols, flavonoids, ascorbic acid) analyses and antioxidant activities such as reducing power, DPPH and ABTS radicals scavenging activities were used to assess antioxidant potentials using standard methods.The results show that regardless of the nature of solvent, boiling resulted in significant reduction in total phenols (P<0.05). The least reduction (36%) was observed......

Abstract: Physical mutagens as X rays, γ rays induce fatality on living system as chromosomal aberrations that eventually lead to cancer. Chromosomal Aberration Test (CAT) is employed as an index of cancer. In the present study, the author has investigated the effect of two different radiations i.e. X rays and γ-rays (1.2 Gy dose) on bone marrow cells of house musk shrew, Suncus murinus. The experimental animals were exposed to whole body irradiations in two different sets. Seven different types of chromosomal aberrations were observed in bone marrow cells of the shrew, after four different time intervals post exposure, as 1 hr, 16 hr, 48 hr and 1 week (168 hr.) As a result, for both the exposures, the maximum percentage of aberration had been obtained after 48 hr of exposure for both the radiations.....
