The use of F. religiosa might be beneficial in inflammatory illnesses and can be used for a variety of health conditions. In this article, we studied the identification of antioxidants using (DPPH) 2, 2-Diphenyl-1-picrylhydrazylradical scavenging activity in Ficus religiosa, as F. religiosa is an important herbal plant, and every part of it has various medicinal properties such as antibacterial properties that can be used by the researchers in the development and design of various new drugs. The 2, 2-Diphenyl-1- picrylhydrazyl (DPPH) is a popular, quick, easy, and affordable approach for the measurement of antioxidant properties that includes the use of the free radicals used for assessing the potential of substances to serve as hydrogen providers or free-radical scavengers (FRS). The technique of DPPH testing is associated with the elimination of DPPH, which would be a stabilized free radical. The free-radical DPPH interacts with an odd electron to yield a strong absorbance at 517 nm, i.e., a purple hue. An FRS antioxidant, for example, reacts to DPPH to form DPPHH, which has a lower absorbance than DPPH because of the lower amount of hydrogen. It is radical in comparison to the DPPH-H form, because it causes decolorization, or a yellow hue, as the number of electrons absorbed increases. Decolorization affects the lowering capacity significantly. As soon as the DPPH solutions are combined with the hydrogen atom source, the lower state of diphenylpicrylhydrazine is formed, shedding its violet color. To explain the processes behind the DPPH tests, as well as their applicability to Ficus religiosa (F. religiosa) in the manufacture of metal oxide nanoparticles, in particular MgO, and their influence on antioxidants, a specimen from the test was chosen for further study. According to our findings, F. religiosa has antioxidant qualities and may be useful in the treatment of disorders caused by free radicals.

Infectious animal diseases caused by pathogenic microorganisms such as bacteria and viruses threaten the health and well-being of wildlife, livestock, and human populations, limit productivity and increase significantly economic losses to each sector. The pathogen detection is an important step for the diagnostics, successful treatment of animal infection diseases and control management in farms and field conditions. Current techniques employed to diagnose pathogens in livestock and poultry include classical plate-based methods and conventional biochemical methods as enzyme-linked immunosorbent assays (ELISA). These methods are time-consuming and frequently incapable to distinguish between low and highly pathogenic strains. Molecular techniques such as polymerase chain reaction (PCR) and real time PCR (RT-PCR) have also been proposed to be used to diagnose and identify relevant infectious disease in animals. However these DNA-based methodologies need isolated genetic materials and sophisticated instruments, being not suitable for in field analysis. Consequently, there is strong interest for developing new swift point-of-care biosensing systems for early detection of animal diseases with high sensitivity and specificity. In this review, we provide an overview of the innovative biosensing systems that can be applied for livestock pathogen detection. Different sensing strategies based on DNA receptors, glycan, aptamers and antibodies are presented. Besides devices still at development level some are validated according to standards of the World Organization for Animal Health and are commercially available. Especially, paper-based platforms proposed as an affordable, rapid and easy to perform sensing systems for implementation in field condition are included in this review.

The production of interleukin-6 (IL-6) has been discovered in a variety of human tumors. Here we report the expression of IL-6, IL-6 receptor a (IL-6Ra), and gp130 in human esophageal carcinoma tissues. We further demonstrate that IL-6 protects an esophageal carcinoma cell line CE48T/VGH from apoptosis induced by staurosporine. IL-6 stimulation induced a rapid phosphorylation of gp130 and STAT3, and a dominant-negative STAT3 completely abolished the antiapoptotic effect. IL-6 also activated ERK 1/2 in CE48T/VGH cells. Inhibition of the ERK activation by PD98059 and transfection of a dominant-negative ERK2 completely blocked the protection of IL-6 against apoptosis. Thus, both STAT and MAP kinase pathways are responsible for the IL-6-delivered survival signal in human esophageal carcinoma cells. In contrast, PI3-K inhibitors only partially attenuated the effect of IL-6, suggesting that PI3-K does not play a major role in the antiapoptotic signal of IL-6 in our system. To investigate whether IL-6 could induce the production of antiapoptotic molecules, proteins of the Bcl-2 family were measured. While Bcl-2, Bcl-x L, , and Bax were not affected, Mcl-1 was induced by IL-6 in human esophageal carcinoma cells. Our results suggest that IL-6 may contribute to the progression of esophageal cancers in an autocrine or paracrine manner.
