    Abstract The present state of diagnostic and therapeutic developmental race for vaccines against the SARS CoV-2 (nCOVID-19) focuses on prevention and control of this global pandemic which also represents a critical challenge to the global health community. Although development of novel vaccines can prevent the SARS CoV-2 infections, it is still impeded by several other factors and therefore novel approaches towards treatment and management of this disease is the urgent need. Passive immunotherapy plays a vital role as a possible alternative to meet this challenge and among various antibody sources, chicken egg yolk antibodies (IgY) can be used as an alternative to mammalian antibodies which have been previously studied against SARS CoV outbreak in China. In this review, we discuss the strategies for the use of chicken egg yolk (IgY) antibodies in the development of rapid diagnosis and immunotherapy against SARS CoV-2. Also, IgY antibodies have previously been used against various respiratory bacterial and viral infections in humans and animals. Compared to mammalian antibodies (IgG), chicken egg yolk antibodies (IgY) have greater binding affinity to specific antigens, ease of extraction and lower production costs, hence possessing remarkable pathogen-neutralizing activity of pathogens in respiratory and lungs. We provide an overall importance for the use of monoclonal chicken egg yolk antibodies (IgY) using phage display method describing their potential passive immunotherapeutic application for the treatment and prevention of SARS CoV-2 infection which is simple, fast and safe way of approach for treating patients effectively.

    Abstract Septal correction is the commonest surgery by rhinologists worldwide. We aimed at studying the comfort level of the patient with standard postoperative nasal packing with Merocel and placing quilting sutures in septum leaving the nose unpacked in the postoperative period. We conducted the study in the tertiary care centre enrolling 82 patients in a quasi-randomised method of odd and even numbers placing them in the nasal packing group and the quilting group respectively. We used analogue scoring method for subjective assessment of comfort level in the postoperative period and the surgeon objectively assessed the patient on follow up. The results were tabulated and analysed. Postoperative pain, headache and sleep disturbance was significantly more in the nasal packing group. We found that the crusting is commonly seen in patients in the nasal packing group. Quilting the nasal septum and leaving the nasal cavity unpacked increases the comfort level of the patient in the postoperative period. The resultant pain, headache and sleep disturbance caused by nasal packing can be significantly avoided by using quilting the septum without nasal packing. We also observed that by avoiding nasal packing postoperatively, the patients were more comfortable and compliant with the treatment regimen and follow-up.

    Abstract Identifying naturally existing abiotic-stress tolerant accessions in cereal crops is central to understanding plant responses towards stress. Salinity is an abiotic stressor that limits crop yields. Salt stress triggers major physiological changes in plants, but individual plants may perform differently under salt stress. In the present study, 112 barley accessions were grown under controlled salt stress conditions (1 Sm−1 salinity) until harvest. The accessions were then analyzed for set of agronomic and physiological traits. Under salt stress, less than 5 % of the assessed accessions (CIHO6969, PI63926, PI295960, and PI531867) displayed early flowering. Only two (< 2 %) of the accessions (PI327671 and PI383011) attained higher fresh and dry weight, and a better yield under salt stress. Higher K+/Na+ ratios were maintained by four accessions PI531999, PI356780, PI452343, and PI532041. These top-performing accessions constitute naturally existing variants within barley’s gene pool that will be instrumental to deepen our understanding of abiotic-stress tolerance in crops.

    Abstract This study employs repeated, large panels of serological surveys to document rapid and substantial waning of SARS-CoV-2 antibodies at the population level and to calculate the extent to which infection and vaccination separately contribute to seroprevalence estimates. Four rounds of serological surveys were conducted, spanning two COVID waves (October 2020 and April-May 2021), in Tamil Nadu (population 72 million) state in India. Each round included representative populations in each district of the state, totaling ≥ 20,000 persons per round. State-level seroprevalence was 31.5% in round 1 (October-November 2020), after India's first COVID wave. Seroprevalence fell to 22.9% in round 2 (April 2021), a roughly one-third decline in 6 months, consistent with dramatic waning of SARS-Cov-2 antibodies from natural infection. Seroprevalence rose to 67.1% by round 3 (June-July 2021), with infections from the Delta-variant induced second COVID wave accounting for 74% of the increase. Seroprevalence rose to 93.1% by round 4 (December 2021-January 2022), with vaccinations accounting for 63% of the increase. Antibodies also appear to wane after vaccination. Seroprevalence in urban areas was higher than in rural areas, but the gap shrunk over time (35.7 v. 25.7% in round 1, 89.8% v. 91.4% in round 4) as the epidemic spread even in low-density rural areas.

    Abstract White Spot Syndrome Virus (WSSV) is one of the most important causative agents of Penaeid shrimps diseases that incur heavy losses to the shrimp aquaculture. It has severe impact on the sustainability and the production of Penaeus monodon. Hence, the present study focussed on the investigation of Poly-β-hydroxybutyrate/biosurfactant as immunostimulants against WSSV infected shrimps. Infection of WSSV was periodically checked in all the experimental shrimps using PCR diagnostic kit. After ensuring all shrimps were free of viral infection, experiments were carried out to analyze the nonspecific immune responses (prophenol oxidase, nitro blue tetrazolium reduction assay and total haemocyte count) both in control and experimental group. Further, gills and muscles of Penaeus monodon were subjected to proteome analysis after treated it with PHB/biosurfactant independently in the concentration of 2% and 5% each. Increase in the level of haemocytes was observed in both PHB (26 ± 2 × 10⁴ cells)/biosurfactant (28 ± 2 × 10

    Abstract Drugs are currently not licensed in specific to pulverize COVID-19. On an emergency basis, vaccines were approved to prevent the further spread of COVID-19. This serves as a potential background for considering the optimization of biologics. In this context, evidence on convalescent plasma and stem cells has shown a beneficial role. Here, we have considered this as plausible therapy, and further hypothesize that their cocktails will synergistically boost the immunogenicity to relegate COVID-19. This warrants a large volume clinical trial on an emergent basis, because the sooner we establish a safe and effective cure, the better.
