Selected LAB were identified as Lactococcus lactis (cam 12), Enterococcus lactis (cam 14) and Lactobacillus plantarum (cam 15) and their potential were tested by tolerance & de-conjugation of bile salts, antimicrobial activity, surface hydrophobicity and adhesion potential) along with this of probiotics were evaluated for curd formation and assessed for sensory properties and syneresis. Selected LABs showed antimicrobial activity against wide range of pathogenic bacteria (Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus cereus and Escherchiaia. coli). LAB (cam 12, cam 14 and cam15) were highly sceptible to chloramphenicol, vancomycin, and tetracyclin. In vitro adhesion studies with Caco-2 cells demonstrated strong adhesion activity with hydrophobicity (99%) was observed. Acute oral toxicity of E. lactis and L. plantarum showed non-toxic, non-virulent and safe for industrial application. The study provides potential LAB which may act as a substitute of functional food, synthetic feed and industrial curd formulation with in the shortest span (240 min at 28-32 °C).This study aimed to investigate the antibiofilm activity of alpha-mangostin (AMG) loaded nanoparticles (nanoAMG) against Staphylococcus aureus, including the methicillin-resistant strain MRSA252. The results indicated that treatment with 24 μmol/L nanoAMG inhibited the formation of biofilm biomass by 53-62%, compared to 40-44% for free AMG (p 50%. In contrast, activity of nanoAMG was limited on preformed mature biofilms, which at a concentration of 48 µmol/L were reduced only by 27% and 22% for NCTC6571 and MRSA252, respectively. The effects of AMG or nanoAMG on the expression of biofilm-related genes showed some noticeable differences between the two strains. For instance, the expression level of ebpS was downregulated in MRSA252 and upregulated in NCTC6571 when those strains were treated with either AMG or nanoAMG. In contrast, the expression of fnbB was down regulated in NCTC6571, while it was up-regulated in the MRSA252. The expression of other biofilm-related genes (icaC, clfB and fnbA) was down regulated in both strains. In conclusion, our results suggest that AMG coated nanoparticles had enhanced biological activity as compared to free AMG, indicating that nanoAMG could be a new and promising inhibitor of biofilm formation to tackle S. aureus, including strains that are resistant to multiple antibiotics.The formation of inflammasome complexes contributes inactivation of inflammatory caspases viz caspase 1, which is generally considered essential for the innate response. Three proteins constituted this inflammasome complex, such as Nod-like receptors (NLRP or AIM2), ASC possessing caspase-recruiting domain, and caspase-1. The ASC proteins comprise two domains, the N-terminal PYD domain responsible for the interaction of various proteins, including PYD only protein 3 (POP3), and the CARD domain for association with other proteins. see more The PYRIN Domain-Only Protein POP3 negatively regulates responses to DNA virus infection by preventing the ALR inflammasome formation. POP3 directly interacts with ASC, therefore inhibiting ASC recruitment to AIM2-like receptors (ALRs). In the current study, we designed various constructs of the PYRIN Domain-Only Protein 3 (POP3) and ASC PYD domain to find the best-overexpressed construct for biochemical characterization as well as our complex studies. We cloned, purified, and characth ASC PYD domain because of oligomerization mediated by the PYD domain.Traditional medicine is becoming a primary source of health care in many countries in recent years. The current study proposes a new dimension of understanding a traditional origin treatment, using herbo-mineral preparations in nanoform. The herbo-mineral preparation, Linga chenduram [HMLC], was prepared according to the ancient palm script protocol dates back to 1000 years. In search of alternative therapy for the coronavirus, an attempt was made to determine this ethnic medicine formulation's therapeutic potential for viral hepatitis infection. The Hepatitis C virus [HCV] has several genomic similarities with SARS-CoV-2 viruses. The herbo-mineral formulation (HMLC) were analyzed using UV-vis, EDAX, FTIR, XRD, SEM, and TEM studies. SEM images confirmed the ' presence of nanoparticles with agglomerated conditions having an average grain size of 18 to 25 nm. EDAX studies showed the presence of metallic components in oxide or sulfide form in HMLC. The HCV inhibitory effects of HMLC indicated a good response. The cytotoxicity of this preparation against the Huh-7 human hepatoma cell line was significant. The HMLC showed a strong inhibitory effect on HCV replication in a dose-dependent manner. The genomic component of HCV is similar to COVID -19 virus. The Hepatitis C virus (HCV) NS3/4A protease has a striking three-dimensional structural similarity to the SARS-CoV2 Mpro protease, particularly in the arrangement of key active site residues. So HMLC can be tried to treat coronavirus infection. At higher concentrations, HMLC exhibited over 100-fold inhibition. In the MTT assay, HMLC did not show any apparent cytotoxic effect on cell viability at the concentrations 1-100 µg. Histological studies indicated that the liver and kidney did not experience any toxicity by 7 and 15 consecutive days of administration of HMLC on experimental Wistar rats. Hence, the HMLC can be tried as a therapy for COVID -19 infections using the preparations strictly according to ethnopharmacological protocol and optimum doses.Venom of Conus inscriptus, a vermivorous cone snail found abundantly in the southern coastal waters was studied to yield conotoxins through proteomic analysis. A total of 37 conotoxins (4 with single disulfide bonds, 20 with two disulfide bonds and 11 three disulfide-bonded peptides) were identified using mass spectrometric analysis. Among them, amino acid sequences of 11 novel conopeptides with one, two and three disulfides belonging to different classes were derived through manual de novo sequencing. Based on the established primary sequence, they were pharmacologically classified into α conotoxins, µ conotoxins and contryphans. Except In1696 all other conopeptides have undergone C-terminal amidation. The natural venom exhibited 50% lethality at 304.82 µg/mL against zebrafish embryo and 130.31 µg/mL against brine shrimp nauplii. The anticonvulsant study of natural venom effectively reduced the locomotor activity against pentylenetetrazole (PTZ) treated zebrafish. This concludes that the venom peptides from Conus inscriptus exhibit potential anticonvulsant function, which leads to the discovery of lead molecules against seizures.
