The inhibitory effects of clove (0.5%) and sodium chloride (1-5%) on the growth and biogenic amine (histamine and cadaverine) production of Enterobacter aerogenes in mackerel muscle broth at 30°C were investigated. At 1% level, sodium chloride was favorable for growth, whereas higher levels slightly reduced the growth in comparison to the control. The maximum population numbers obtained in the presence of sodium chloride were essentially the same as that of the control. Amine production was remarkably enhanced by the presence of 1 % NaCl alone. Only a little increase was observed for higher levels, and sodium chloride at more than 3% had no stimulatory effect on the amine formation. Addition of clove at a level of 0.5% to the broth resulted in a delay in the growth and the amine formation. The presence of NaCl as low as 2% in combination with clove (0.5%) completely inhibited the growth and amine production of E. aerogenes in mackerel broth. Synergistic effects of clove essential oils and sodium chloride could be considered as the probable reason for the inactivation of the bacterium.

Surface water chemistry of the River Ganga at Varanasi was analyzed at 10 locations over 3 years (2019-2021) across pre-monsoon, monsoon, and post-monsoon seasons. The study aimed to assess water parameters using principal component analysis (PCA), calculate the water quality index (WQI), determine processes governing water chemistry, evaluate irrigation suitability, and estimate non-carcinogenic health risks. The physical parameters measured included pH (8.

Objective: The effect of sodium intake on atrial fibrillation (AF)/atrial flutter (AFL), with respect to sex and age, has yet to be elucidated. This study aims to compare long-term trends in AF/AFL death and disability due to high sodium intake in China from 1990 to 2019.
Methods: We utilized data from the Global Burden of Disease study to assess the mortality and disability burden of AF/AFL attributable to high sodium intake (> 5 g/d) in China from 1990 to 2019.

Background And Objectives: Gingivitis and periodontitis are common periodontal diseases that can significantly harm overall oral health, affecting the teeth and their supporting tissues, along with the surrounding anatomical structures, and if left untreated, leading to the total destruction of the alveolar bone and the connective tissues, tooth loss, and other more serious systemic health issues. Numerous studies have shown that propolis can help reduce gum inflammation, inhibit the growth of pathogenic bacteria, and promote tissue regeneration, but with varying degrees of success reported. For this reason, this comprehensive systematic review aims at finding out the truth concerning the efficacy of propolis mouthwashes in treating gingivitis and periodontitis, as its main objective.

In order to solve the problems of long dissolution and preparation time, cumbersome preparation, and easy moisture absorption and deterioration during storage or transportation, acrylamide (AM), acrylic acid (AA), sodium p-styrene sulfonate (SSS), and cetyl dimethylallyl ammonium chloride (DMAAC-16) were selected as raw materials, and the emulsion thickener P(AM/AA/SSS), which can be instantly dissolved in water and rapidly thickened, was prepared by the reversed-phase emulsion polymerization method. DMAAC-16, the influence of emulsifier dosage, oil-water ratio, monomer molar ratio, monomer dosage, aqueous pH, initiator dosage, reaction temperature, reaction time, and other factors on the experiment was explored by a single-factor experiment, and the optimal process was determined as follows: the oil-water volume ratio was 0.4, the emulsifier dosage was 7% of the oil phase mass, the initiator dosage was 0.
