Unlocking sustainable solutions: Nanocellulose innovations for enhancing the shelf life of fruits and vegetables - A comprehensive review.

Regarding food security and waste reduction, preserving fruits and vegetables is a vital problem. This comprehensive study examines the innovative potential of coatings and packaging made of nanocellulose to extend the shelf life of perishable foods. The distinctive merits of nanocellulose, which is prepared from renewable sources, include exceptional gas barrier performance, moisture retention, and antibacterial activity.

Preparation and Characterization of Magnetite-Polyvinyl Alcohol Hybrid Nanoparticles (As-PVA-MNPs) Using Acanthophora spicifera Marine Algae Extract for Enhanced Antimicrobial Activity Against Pathogenic Microorganisms.

The present study focused on preparing and characterizing magnetite-polyvinyl alcohol (PVA) hybrid nanoparticles using Acanthophora spicifera marine algae extract as a reducing agent. Various analytical techniques, including UV-Visible spectrometry, Fourier-transform infrared (FTIR) analysis, energy-dispersive X-ray (EDX), scanning electron microscopy (SEM), and X-ray diffraction (XRD) analysis, were used to characterize the nanoparticles. The results showed the successful synthesis of nanoparticles with a characteristic color change and absorption peak at 400 nm in UV-Visible spectrometry.

Temporal pattern and risk factors for occurrence of Canine Rabies in Chennai.

Rabies is one of the most important zoonoses resulting in a high case fatality rate in humans. Most of the human Rabies cases are due to dog bites which can be prevented by effective vaccination in dogs. Globally, epidemiological studies on understanding the seasonality and risk factors for occurrence in canines are limited.

Incidence of Dental Caries in Relation to Sweet Taste Perception and Dietary Habits among Students - A Cross Sectional Study.

Aim: The aim of the study was to evaluate the impact of sweet taste perception on dietary habits among students. Furthermore, the relationship between dietary habits and caries was studied.

Methodology: cross-sectional study was conducted among 200 college-going students aged 18-23 years from the Asan Memorial Institutions.

Design and Characterisation of Inhibitory Peptides against Bleg1_2478, an Evolutionary Divergent B3 Metallo-β-lactamase.

Previously, a hypothetical protein (HP) termed Bleg1_2437 (currently named Bleg1_2478) from G1 was discovered to be an evolutionary divergent B3 subclass metallo-β-lactamase (MBL). Due to the scarcity of clinical inhibitors for B3 MBLs and the divergent nature of Bleg1_2478, this study aimed to design and characterise peptides as inhibitors against Bleg1_2478. Through in silico docking, RSWPWH and SSWWDR peptides with comparable binding energy to ampicillin were obtained.

Herd-level risk factors for bovine viral diarrhea infection in cattle of Tamil Nadu.

A cross-sectional study was carried out to identify risk factors for bovine viral diarrhea virus (BVDV) infection in 62 randomly selected dairy herds which were tested for BVD serum antibodies by using an indirect ELISA kit (IDEXX). Results from the chi-square test analysis were interpreted by analyzing by chi-square test. A sum of 500 sera samples were screened and 66 animals (13.

Development of indirect enzyme-linked immunosorbent assay for diagnosis of canine leptospirosis.

Aim: This study was taken up to develop an indirect enzyme-linked immunosorbent assay (i-ELISA) for screening antibodies against spp. in canines.

Materials And Methods: An i-ELISA was developed using outer membrane protein extracted from serovar used for coating the well with concentration of 0.

Shade selection of primary maxillary anterior teeth in children using Vitapan classical shade guide.

Aim: The purpose of this study was to determine the closest matching shade for primary maxillary anterior teeth from the most widely used Vitapan classical shade guide available for permanent teeth.

Materials And Methods: A total of 313 children aged between 3 and 5 years were evaluated. Vitapan classical shade guide was used to determine the shade of six primary maxillary anterior teeth.

Effectiveness of new vibration delivery system on pain associated with injection of local anesthesia in children.

Aim: Pain is highly subjective and it is neurologically proven that stimulation of larger diameter fibers - e.g., using appropriate coldness, warmth, rubbing, pressure or vibration - can close the neural "gate" so that the central perception of itch and pain is reduced.

Comparative evaluation of fluoride release and recharge of pre-reacted glass ionomer composite and nano-ionomeric glass ionomer with daily fluoride exposure: an in vitro study.

Aim: This in vitro study was designed to investigate the effects of daily fluoride exposures on fluoride release and recharge by prereacted glass ionomer (PRG) composite and nano-ionomeric glass ionomer.

Materials And Methods: Seventy-two specimens (36 of each material) were prepared and by placing the restorative materials into Teflon mold. Each specimen was subjected to one of three daily treatments (n = 12): (1) No fluoride treatment (control); (2) application of a fluoride dentifrice (1,000 ppm) once daily; and (3) the same regimen as (2), plus immersion in a 0.

Child's dental fear: cause related factors and the influence of audiovisual modeling.

Background: Delivery of effective dental treatment to a child patient requires thorough knowledge to recognize dental fear and its management by the application of behavioral management techniques. Children's Fear Survey Schedule - Dental Subscale (CFSS-DS) helps in identification of specific stimuli which provoke fear in children with regard to dental situation. Audiovisual modeling can be successfully used in pediatric dental practice.

Doxycycline propylaxis for human scrub typhus.

The use of doxycycline, as a prophylactic antibiotic against scrub typhus was investigated in a prospective, randomized, double-blind study. Twenty volunteers were divided into two similar groups. Beginning three days before exposure to Leptotrombidium fletcheri chiggers infected with Rickettsia tsutsugamushi, and continuing for six weeks after exposure, one group received weekly 200-mg oral doses of doxycycline and the other group received a placebo.
