A simple approach for synthesis, characterization and bioactivity of bovine bones to fabricate the polyurethane nanofiber containing hydroxyapatite nanoparticles

In the present study, we had introduced polyurethane (PU) nanofibers that contain hydroxyapatite (HAp) nanoparticles (NPs) as a result of an electrospinning process. A simple method that does not depend on additional foreign chemicals had been employed to synthesize HAp NPs through the calcination of bovine bones. Typically, a colloidal gel consisting of HAp/PU had been electrospun to form nanofibers. In this communication, physiochemical aspects of prepared nanofibers were characterized by FE-SEM, TEM and TEM-EDS, which confirmed that nanofibers were well-oriented and good dispersion of HAp NPs, over the prepared nanofibers. Parameters, affecting the utilization of the prepared nanofibers in various nano-biotechnological fields have been studied; for instance, the bioactivity of the produced nanofiber mats was investigated while incubating in simulated body fluid (SBF). The results from incubation of nanofibers, indicated that incorporation of HAp strongly activates the precipitation of the apatite-like particles, because of the HAp NPs act as seed, that accelerate crystallization of the biological HAp from the utilized SBF

Do the home field, global advantage, and liability of unfamiliarness hypotheses hold? empirical evidence from Malaysia

The study explores the home field, global advantage, and liability of unfamiliarness hypotheses in the Malaysian banking sector. The results indicate that Malaysian banks have exhibited productivity progress mainly attributed to technological progress. The authors find negative relationship between foreign and government ownership and bank productivity. Likewise, the publicly listed banks have been relatively less productive compared to private banks, thus rejecting the market discipline hypothesis. The empirical findings suggest that foreign banks from the North American countries to be the least productive banking group lending support to the home field advantage and the limited form of the global advantage hypotheses

Assessing ethno-veterinary practices in Kashmir Himalayas: Traditional knowledge and its role in animal healthcare

This study was aimed at exploring the ethno-veterinary practices in the District of Kupwara in Jammu and Kashmir Union Territory of India, by examining the traditional knowledge and its application in animal healthcare. The study included qualitative methods, such as interviews with local farmers (n=100) and traditional healers, as well as observation of their practices from February to April 2023. The results revealed a rich knowledge base among the local community regarding the use of medicinal plants for treating a range of animal ailments. 32 plants of pharmaceutical value representing 23 families have been assessed, with the Asteraceae family receiving the greatest attention. Eighty-eight percent of these ethnoveterinary medicinal plant species were herbs. Leaves of these plants were used most often (27%), followed by the entire plant (21%), seeds (21%), roots and fruits (9%), bulbs (6%), and stems and rhizomes (3%). Glycine max (0.91) and Allium sativum (UVi = 0.89) had the highest UVi values, whereas Oryza sativa (0.51), Allium sativum (0.49), and Zea mays (0.43) were the most cited and most often mentioned therapeutic plant species. Traditional veterinary practices were found to be deeply embedded in the local culture and were passed down through generations of farmers and traditional healers. These practices are still widely used today, in combination with modern veterinary medicine, to provide comprehensive care to livestock in the region. This study highlights the importance of preserving and promoting ethno-veterinary knowledge and practices as a valuable resource for animal healthcare in rural communities

Design and characterization of impedance based e. Coli sensor

Foodborne illness has become a concern due to high disease rate and huge losses caused. It is critical to detect and identify the pathogen in food by using sensor. However the conventional methods for pathogen detection are quite time-consuming, costly and label-dependent. This paper presents the design, fabrication and characterization of the impedance based biosensor for the detection of E. coli in water with features of low cost, rapid detection, easy to use and label-free. The interdigital electrodes and microfluidic system based devices were tested in different concentrations of E. coli samples with different structure electrode parameters for sensor characterization. Impedance analyzer was used for monitoring the impedance change to determine the operating frequency. The fabricated interdigital electrodes are also able to discriminate between dry and wet conditions by presenting different impedance outcomes at low frequency. The results depicted in this paper provide a guideline for detection of E. coli contamination level at different concentration with corresponding impedance range
