Abstract

Purpose

The purpose of this study is to evaluate the effects of prebiotic, probiotic and synbiotic supplementation on liver histopathology and TLR-4, NFκB and TNF-α gene expression involved in the inflammatory cascade and pathogenesis of experimental nonalcoholic fatty liver disease (NAFLD).

Design/methodology/approach

Wistar male adult rats (n = 40) were submitted to hypercholesterolemic conditions (60 days). On Day 30 of hypercholesterolemic conditions, rats were subdivided in five groups: negative control (NC), positive control (PC), prebiotic (PRE), probiotic (PRO) and synbiotic (SYN). All rats were sacrificed on Day 60. Liver tissue was used to verify histopathological changes and gene expression. Gene expression of TLR-4, TNF-α and NFκB was evaluated in liver tissue using RT-qPCR.

Findings

Histopathological analysis: PC showed more changes than NC, and PRE and SYN showed fewer alterations than PC. Gene expression analysis: PRE showed higher TLR-4, and NFκB and TNF-α compared to PC. Also, PRE showed higher TLR-4 when compared to PRO and SYN. SYN group revealed higher TLR-4 and NFκB expressions compared to PC. PRO group also showed higher NFκB expression compared to PC.

Originality/value

NAFLD is a significant health concern, and it found that prebiotic, probiotic and synbiotic supplementation could have positive effects as a nonpharmacological approach to control this disease.

Abstract

Purpose

This study aims to conduct a systematic literature review to investigate the mental health problems during COVID-19 and the role of nutrition in minimizing mental and health-related issues during COVID-19.

Design/methodology/approach

A literature search was done electronically on April–May 2022 in the databases Google Scholar, PubMed and Cochrane Library, reviewing all the articles published in English. There were no limitations for the study (such as study design, region or any time frame). The quality assessment was done. The beginning database search picked out a total of 654 articles, 47 in PubMed, 575 in Google Scholar, 22 in Cochrane Library and 10 records from other sources. A total of 565 (duplicates found 89) were found after removing the duplicated articles, after reading the title and abstracts were further decreased to 88 full-text articles. These 88 studies went for full-text analysis, which excluded 56 studies and generated a final 32 articles for systemic analysis. The quality of the included study for the systematic review was assessed in two ways: one is evidence-based and another one on the JBI checklist.

Findings

People in social isolation and home quarantine suffer from severe anxiety, stress, depression, loneliness, anger and panic attack. During COVID-19, the vital role of diet and nutrients in mental health has been acknowledged and helps mitigate COVID-19 infection. Many studies showed stress and anxiety due to increased unhealthy eating and lifestyle practices.

Originality/value

This review will explain the interlink between diet and mental health because what we eat and think is interconnected with the gut–brain axis. The dietary elements and psychobiotic help in improving the immune system and psychological distress during the pandemic. This paper describes the role of different nutrients, psychobiotics and phytochemicals, to minimize mental and health issues during the COVID-19 pandemic. This paper also contains a balanced diet plan to withstand COVID-19.

Abstract

Purpose

Renal failure is an end-stage consequence after persistent hyperglycemia during diabetic nephropathy (DN), and the etiology of DN has been linked to oxidative stress. The purpose of this research was to determine the beneficial synergistic effects of S-Allyl Cysteine (SAC) and Taurine (TAU) on oxidative damage in the kidneys of type 2 diabetic rats induced by hyperglycemia.

Design/methodology/approach

Experimental diabetes was developed by administering intraperitoneal single dose of streptozotocin (STZ; 65 mg/kg) with nicotinamide (NA; 230 mg/kg) in adult rats. Diabetic and control rats were treated with SAC (150 mg/kg), TAU (200 mg/kg) or SAC and TAU combination (75 + 100 mg/kg) for four weeks. The estimation of body weight, fasting blood glucose (FBG), oral glucose tolerance test (OGTT), oxidative stress markers along with kidney histopathology was done to investigate the antidiabetic potential of SAC/TAU in the NA/STZ diabetic group.

Findings

The following results were obtained for the therapeutic efficacy of SAC/TAU: decrease in blood glucose level, decreased level of thiobarbituric acid reactive substances (TBARS) and increased levels of GSH, glutathione-s-transferase (GST) and catalase (CAT). SAC/TAU significantly modulated diabetes-induced histological changes in the kidney of rats.

Originality/value

SAC/TAU combination therapy modulated the oxidative stress markers in the kidney in diabetic rat model and also prevented oxidative damage as observed through histopathological findings.
