The highly active Ni/Cu bimetallic nanoparticles (NPs) of the different molar ratios of Ni and Cu (1:1, 1:3, 3:1) assisted by dendritic ligand 2,4,6-Tris (di-4-chlorobenzamido)-1,3-diazine were synthesized successfully confirmed by Scanning Electron Microscopy (SEM), Electron Diffraction X-ray (EDX), X-ray fluorescence spectroscopy (XRF), X-ray diffraction (XRD), and Transmission Electron Microscopy (TEM) analysis. These NPs were studied as a heterogeneous catalyst for the chemoselective oxidation of alcohol to the corresponding aldehyde at 30 min and chemoselective reduction of aromatic nitro substituents to the corresponding amino substituents at 20 min, while the Ni/Cu (3:1) NPs were found to be the most effective among other Ni/Cu (1:1) and Ni/Cu (1:3) NPs at room temperature under mild conditions. The Ni/Cu (3:1) NPs can be recycled for at least five successive runs with no perceptible decrease in catalytic activity.

Salmonella is one of the etiological agents of intestinal illness as well as typhoid and paratyphoid feverthroughout the world. While food is known to be a common vehicle for the transmission of typhoidalSalmonella serovars, non-typhoidal Salmonella are mainly known as foodborne pathogens. But recentstudies found water as vehicle for transmission of Salmonella serovars. And several studies have showedthe role of contaminated water in Salmonella foodborne illness. So, this paper provides a brief review ofthe last twenty years of peer reviewed publications on the prevalence of Salmonella in environmental water,and relationship between contaminated water and Salmonella foodborne infections. Salmonella representzoonotic bacteria that are distributed throughout the world. Data relating to Salmonella prevalence in waterindicated a mixed human and animal origin of Salmonella contribution to water contamination. This studyhas also emphasized on the role of these contaminated water in occurring Salmonella foodborne diseasesand its implication on global public health problem.

Objective: This study was undertaken to compare the curative efficacy of marigold leaf paste and turmeric paste on healing the incised wound in sheep. The study also determined the anti¬microbial effects and histopathological changes in a wounds healing process treated with these medicinal herbs. Materials and Methods: Surgical wounds (n = 18) were created aseptically in the skin of the flank region of six healthy sheep dividing them into three experimental groups. Follow-up data were taken up to day 21. Different morphological characteristics of the wound and wound contraction (length and width) were recorded weekly. Samples were collected on days 1, 2, and 3 to test the antimicrobial effects and on days 1, 3, and 7 for histopathological studies. Results: Treatment with marigold leaf paste and turmeric paste resulted in a swelled wound area of 11.78 ± 0.38 mm and 11.52 ± 0.27 mm, respectively. The wound areas were comparatively lower than that of the control group (11.44 ± 0.20 mm). Moreover, the least elevation (2.44 ± 0.12 mm) of the sutured line from the skin surface was noted and compared between the marigold leaf paste and normal saline (2.74 ± 0.13 mm). Bacterial colonies in the nutrient agar medium cultured with swabs from the normal saline-treated groups wound area were found on day 1. On the con¬trary, bacterial colonies were absent on days 2 and 3 of treatment in the groups treated with both the paste of marigold leaves and turmeric. Less intense tissue reactions and higher keratinization of epithelium were shown in the group treated with marigold leaf paste than turmeric paste and saline-treated groups. Conclusion: Marigold leaf paste showed less tissue reaction and healed the wounds effectively. Thus, this paste could be used for the treatment of superficial wounds in sheep.
