Development of a rapid antigen-based lateral flow assay for tick-borne spotted fever rickettsioses.

Tick-borne spotted fever rickettsioses (SFRs) continue to cause severe illness and death in otherwise-healthy individuals due to lack of a timely and reliable diagnostic laboratory test. We recently identified a diagnostic biomarker for SFRs, the putative N-acetylmuramoyl-l-alanine amidase RC0497. Here, we developed a prototype laboratory test that targets RC0497 for diagnosis of SFRs.

Genome wide landscaping of copy number variations for horse inter-breed variability.

Copy number variations (CNVs) have become widely acknowledged as a significant source of genomic variability and phenotypic variance. To understand the genetic variants in horses, CNVs from six Indian horse breeds, Manipuri, Zanskari, Bhutia, Spiti, Kathiawari and Marwari were discovered using Axiom Equine Genotyping Array. These breeds differed in agro-climatic adaptation with distinct phenotypic characters.

Discovering the Untouched Perspective of Endangered North American Herb Actaea racemosa.

Actaea racemosa (AR), sometimes also known as black cohosh, is a perennial herb that grows in the Ranunculaceae family that effloresces in the middle of summer. This herb is currently present throughout south and west North America despite being endangered in the eastern section of the continent. Certain information about the photochemistry and biological potential of this herb is available.

Rapid Detection of Explicit Volatile Organic Compounds for Early Diagnosis of Lung Cancer Using MoSiN Monolayer.

In this study, we investigate the adsorption and sensing capabilities of pristine (MoSiN) and nitrogen-vacancy induced (MoSiN-V) monolayers towards five potential lung cancer volatile organic compounds (VOCs), such as 2,3,4-trimethylhexane (CH), 4-methyloctane (CH), o-toluidine (CHN), Aniline (CHN), and Ethylbenzene (CH). Spin-polarized density functional theory (DFT) calculations reveal that MoSiN weakly adsorb the mentioned VOCs, whereas the introduction of nitrogen vacancies significantly enhances the adsorption energies ( ), both in gas phase and aqueous medium. The MoSiN-V monolayers exhibit a reduced bandgap and facilitate charge transfer upon VOCs adsorption, resulting in enhanced values of -0.

Antiviral and Cytoprotective Effect of Zinc (Yasad Bhasma) Based Nanoformulations Against Bovine Coronavirus.

Ayurvedic medicine utilizes metal-based preparations, known as bhasmas, to treat various health conditions. Yasad bhasma (YB), a zinc-based ayurvedic preparation, shows promise as a potential candidate for developing zinc-based nanomedicines with anti-inflammatory and antioxidant properties. In this study, we synthesized a formulation combining YB and hydroxychloroquine (HC) as a zinc ionophore (YBHC) and investigated its biocompatibility and antiviral effects against buffalo calf coronavirus (BCoV) in Vero cells.

Effect of isolation protocols and cryoprotectants on freezing of stallion epididymal spermatozoa.

Background: The recovery of spermatozoa from the cauda epididymis may be the only option to obtain genetic material from elite stallions that had undergone castration or sudden death due to colic or severe injury.

Objective: To evaluate two different protocols for retrieval of stallion epididymal spermatozoa and to evaluate different cryoprotectants on the freezability of the epididymal spermatozoa.

Materials And Methods: Six epididymides from three stallions were collected immediately after routine castration under general anesthesia.

Heterologous Seminal Plasma Reduces the Intracellular Calcium and Sperm Viability of Cryopreserved Stallion Spermatozoa.

Despite the vital role of seminal plasma (SP) in maintaining sperm function and aiding gamete interaction in many species, SP is usually removed before cryopreservation of stallion sperm to improve cryosurvival of sperm. The present study assessed if the vital sperm functional parameters of genetically superior stallions producing poor quality semen can be enhanced by the supplementation of heterologous SP from the stallion producing high quality semen. Spermatozoa from poor quality semen producing stallions were divided into three aliquots: two aliquots were supplemented with SP obtained from good quality semen producing stallions at the rate of 20% and 30%, respectively, whereas the third aliquot remained as control (0% SP) and incubated at 37°C for 30 minutes.

Synergistic Effect of Zinc-Chitosan Nanoparticles and Hydroxychloroquine to Inhibit Buffalo Coronavirus.

Zinc ions can hinder the synthesis of proteins required for accomplishing several stages of the viral life cycle. The intracellular zinc concentration can be increased by using zinc ionophores which transport zinc ions into the cells and hinder viral replication. (Hydroxy)chloroquine is an example of a zinc ionophore, but both zinc and (hydroxy)chloroquine can be toxic to the host organism.

Evidence of lumpy skin disease virus infection in camels.

Countries in the Indian subcontinent are currently facing a deadly epidemic of lumpy skin disease (LSD).  LSD is primarily a disease of cattle. Buffaloes may sometimes develop mild illness, however, other domestic animals are considered resistant to LSD.

Evaluation of the safety, immunogenicity and efficacy of a new live-attenuated lumpy skin disease vaccine in India.

Lumpy skin disease (LSD) was reported for the first time in India in 2019 and since then, it has become endemic. Since a homologous (LSD-virus based) vaccine was not available in the country, goatpox virus (GPV)-based heterologous vaccine was authorized for mass immunization to induce protection against LSD in cattle. This study describes the evaluation of safety, immunogenicity and efficacy of a new live-attenuated LSD vaccine developed by using an Indian field strain, isolated in 2019 from cattle.

A comprehensive profiling of vitamins, minerals, and amino acids was also carried out. It was found that the composition of Halari donkey milk was consistent with previously published donkey milk literature and was comparable to that of human milk.

ROCK1/MLC2 inhibition induces decay of viral mRNA in BPXV infected cells.

Rho-associated coiled-coil containing protein kinase 1 (ROCK1) intracellular cell signaling pathway regulates cell morphology, polarity, and cytoskeletal remodeling. We observed the activation of ROCK1/myosin light chain (MLC2) signaling pathway in buffalopox virus (BPXV) infected Vero cells. ROCK1 depletion by siRNA and specific small molecule chemical inhibitors (Thiazovivin and Y27632) resulted in a reduced BPXV replication, as evidenced by reductions in viral mRNA/protein synthesis, genome copy numbers and progeny virus particles.

Resistance Evolution against Host-directed Antiviral Agents: Buffalopox Virus Switches to Use p38-ϒ under Long-term Selective Pressure of an Inhibitor Targeting p38-α.

Host-dependency factors have increasingly been targeted to minimize antiviral drug resistance. In this study, we have demonstrated that inhibition of p38 mitogen-activated protein kinase (a cellular protein) suppresses buffalopox virus (BPXV) protein synthesis by targeting p38-MNK1-eIF4E signaling pathway. In order to provide insights into the evolution of drug resistance, we selected resistant mutants by long-term sequential passages (P; n = 60) in the presence of p38 inhibitor (SB239063).

Uncovering the structure and function of specialist bacterial lineages in environments routinely exposed to explosives.

Environmental contamination by hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), the two most widely used compounds for military operations, is a long-standing problem at the manufacturing and decommissioning plants. Since explosives contamination has previously been shown to favour the growth of specific bacterial communities, the present study attempts to identify the specialist bacterial communities and their potential functional and metabolic roles by using amplicon targeted and whole-metagenome sequencing approaches in samples collected from two distinct explosives manufacturing sites. We hypothesize that the community structure and functional attributes of bacterial population are substantially altered by the concentration of explosives and physicochemical conditions.

A Systematic Review of the Bioactive Components, Nutritional Qualities and Potential Therapeutic Applications of Donkey Milk.

In addition to providing individualized, specific, and ample nutritional compounds, donkey milk (DM) offers immunological modulation during health and disease. Recently, DM has attracted major interest in preparing infant formulas due to its similarity to human milk in terms of high protein and lactose content and low-fat concentration. The antimicrobial, anti-inflammation, antioxidant, and hypo-allergenicity properties of DM in human infants are well-documented.

High throughput deep proteomic analysis of seminal plasma from stallions with contrasting semen quality.

Seminal plasma proteins and pathways associated with sperm motility have not been elucidated in stallions. Therefore, in the current study, using the high throughput LC/MS-MS approach, we profiled stallion seminal plasma proteins and identified the proteins and pathways associated with sperm motility. Seminal plasma from six stallions producing semen with contrasting sperm motility ( = 3 each high-and low-motile group) was utilized for proteomic analysis.
