Abstract
The consumption of bovine milk and its derivatives is associated with inflammation, gastrointestinal disorders and the development of diseases in humans. Most studies related to milk effects are based on either clinal trials or experimental models such as mice and cell cultures. In this study we present the nematode Caenorhabditis elegans as an alternative model to evaluate the effects of milk on oxidative stress in other animal models. The toxicological effect of 20% milk exposure for 8 h on C. elegans was evaluated by progeny quantification, body size and pharyngeal pumping rate. Treating the worms with milk did not affect the worms brood size but interfered with their fecundity by delaying the average number of eggs in the first day of oviposition when compared to the control group. The size of worms treated with milk were significantly smaller compared to control. The pharyngeal pumping rate of milk-treated animals was not significantly different compared to untreated animals. Taking together, the results suggest that 20% milk treatment is not toxic for the worms but induces a minor delay achieving its adulthood and therefore its reproduction period. Milk exposure did not reduce the worms' survival under stress conditions and increase endogenous ROS levels. This study contributes to characterize the effects of milk exposure on the C. elegans nematode.

Fortification of Fermented Camel Milk with Salvia officinalis L. or Mentha piperita Leaves Powder and Its Biological Effects on Diabetic Rats. Molecules 2023; 28:5749. [PMID: 37570720 PMCID: PMC10420823 DOI: 10.3390/molecules28155749] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Revised: 07/17/2023] [Accepted: 07/24/2023] [Indexed: 08/13/2023] Open
Abstract
The incorporation of fermented camel milk with natural additives possesses numerous benefits for the treatment of various pathological and metabolic conditions. The present study investigated the impact of fortification of fermented camel milk with sage or mint leaves powder (1 and 1.5%, respectively) on glucose and insulin levels, lipid profile, and liver and kidney functions in alloxan-induced diabetic rats. The gross chemical composition of sage and peppermint leaves powder was studied. The chemical composition of sage and mint extracts was performed using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-MS) of sage and mint extracts. Furthermore, a total of forty-two adult normal male albino rats were included in this study, whereas one group was kept as the healthy control group (n = 6 rats) and diabetes was induced in the remaining animals (n = 36 rats) using alloxan injection (150 mg/kg of body weight). Among diabetic rats groups, a control group (n = 6 rats) was kept as the diabetic control group whereas the other 5 groups (6 rats per group) of diabetic rats were fed fermented camel milk (FCM) or fermented camel milk fortified with 1 and 1.5% of sage or mint leaves powder. Interestingly, the oral administration of fermented camel milk fortified with sage or mint leaves powder, at both concentrations, caused a significant decrease in blood glucose level and lipid profile, and an increase in insulin level compared to the diabetic control and FCM groups. Among others, the best results were observed in the group of animals that received fermented camel milk fortified with 1.5% sage powder. In addition, the results revealed that the fermented camel milk fortified with sage or mint leaves powder improved the liver and kidney functions of diabetic rats. Our study concluded that the use of sage and mint leaves powder (at a ratio of 1.5%) with fermented camel milk produces functional food products with anti-diabetic activity.

Biochemical characterization and insights into the potency of the acidic Aspergillus niger NRC114 purified α-galactosidase in removing raffinose family oligosaccharides from soymilk yogurt. BMC Biotechnol 2023; 23:3. [PMID: 36721204 PMCID: PMC9887927 DOI: 10.1186/s12896-023-00773-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Accepted: 01/20/2023] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Because humans lack α-galactosidase, foods containing certain oligosaccharides from the raffinose family, such as soybeans and other legumes, may disrupt digestion and cause flatulence. RESULTS Aspergillus niger NRC114 α-galactosidase was purified using protein precipitation, gel filtration, and ion exchange chromatography steps, which resulted in a 123-fold purification. The purified enzyme was found to be 64 kDa using the SDS-PAGE approach. The optimum pH and temperature of the purified α-galactosidase were detected at pH 3.5 and 60 ºC, respectively. The pure enzyme exhibited potent acidic pH stability at pH 3.0 and pH 4.0 for 2 h, and it retained its full activity at 50 ºC and 60 ºC for 120 min and 90 min, respectively. The enzyme was activated using 2.5 mM of K+, Mg2+, Co2+, or Zn2+ by 14%, 23%, 28%, and 11%, respectively. The Km and Vmax values of the purified enzyme were calculated to be 0.401 µM and 14.65 μmol min-1, respectively. The soymilk yogurt showed an increase in its total phenolic content and total flavonoids after enzyme treatment, as well as several volatile compounds that were detected and identified using GC-MS analysis. HPLC analysis clarified the enzymatic action in the hydrolysis of raffinose family oligosaccharides. CONCLUSION The findings of this study indicate the importance of A. niger NRC114 α-galactosidase enzyme for future studies, especially its applications in a variety of biological fields.

Abstract
Abstract
Background
Diabetes mellitus is a metabolic disorder that affects the body’s ability to produce or use insulin. There is a continuous rise of this disease particularly in developing countries due to changes in life style and poverty among the people. In this study, antidiabetic activities of aqueous extract of Nelsonia canescens and its partitioned fractions in alloxan-induced diabetic rats were evaluated. Male albino rats were divided into 9 groups (diabetic and non-diabetic) of 5 rats each. Diabetes was induced by single intraperitoneal administration of alloxan (90 mg/kgbwt). The experimental design consists of a diabetic control group (untreated), a normal control group (1 mL saline), a standard diabetic drug (Glibenclamide; 5 mg/kgbwt), two doses (50 and 300 mg/kgbwt) of aqueous extract, ethyl acetate and methanol fractions of Nelsonia canescens were orally administered for a period 21 days. Blood glucose of the rats was monitored at 3-days intervals while biochemical and in vivo antioxidant assays of serum and liver were determined after 21 days.
Results
The hypoglycemic effect of the extract observed was in a dose dependent manner with a significant reduction (p < 0.05) of blood glucose in ethylaceate fraction > aqueous extract > methanol fraction compared with the diabetic control group. A significant difference (p < 0.05) in lipid profiles and serum enzyme activity of rats in the diabetic control group was observed compared with the extract and fraction treated groups.
Conclusion
The results suggest that the aqueous extract and fractions of N. canescens showed hypoglycemic and hypolipidemic potentials and significantly (p < 0.05) reduced the progression of oxidative stress.

Abstract
The global prevalence of diabetes mellitus is rapidly increasing. This disease is associated with many complications including male reproductive dysfunctions and infertility. Seahorse ( Hippocampus kuda) is a marine teleost fish well known for its beneficial effects on the reproductive system in traditional Chinese medicine books. Recently, several studies have been shown that the enzymatic hydrolysate of seahorse has multiple pharmacological activities. This study aimed to investigate the seahorse peptide hydrolysate (SH) ameliorative effects on the diabetic-induced male reproductive dysfunction in rat models. The in vivo studies were carried out with three different doses of SH (4, 8, and 20 mg/kg) and the diabetes condition was induced by administrating with streptozotocin (35 mg/kg) and fed a 40% high-fat diet. Seahorse hydrolysate (20 mg/kg) inhibited lipid peroxidation, increased antioxidant enzyme activity, and restored seminiferous tubules morphology in testis. Moreover, it improved reproductive dysfunction by increasing the level of testosterone, follicle-stimulating hormone, luteinizing hormone, sperm count, and motility. According to these results, we suggested that SH exhibited amelioration effects on the reproductive dysfunction.

Abstract
The replacement of animal with plant proteins in human diets has been increasing in recent years. The impact of blending milk protein concentrate (MPC) with protein isolates from soy (SPI), rice (RPI) and pea (PPI) on the in vitro digestibility and antioxidant activity of the resultant blends was investigated. Different plant protein–MPC blends (i.e., SPI–MPC (25:75), RPI–MPC (50:50) and PPI–MPC (25:75)) were analyzed. The lowest protein digestibility corrected amino acid score (PDCAAS) was associated with RPI (0.70), while the blends had PDCAAS values above 1.00 demonstrating the high digestibility of the proteins in the blends studied. An in vitro simulated gastrointestinal digestion was carried out on the samples. The degree of hydrolysis and gel permeation high performance liquid chromatography profiles showed that the SPI–MPC blend was more extensively digested in the gastric phase compared with the two other blends, while the PPI–MPC and RPI–MPC blends were mainly digested during the intestinal phase. The SPI–MPC digested blend had the highest 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity having a half maximal effective concentration (EC50) of 0.10 ± 0.01 mg/mL. The findings show that blends of plant protein with MPC had higher in vitro digestibility and antioxidant activity compared to the individual plant protein isolates.

Abstract
Bioactive peptides (BPs) are fragments of 2-15 amino acid residues with biological properties. Dietary BPs derived from milk, egg, fish, soybean, corn, rice, quinoa, wheat, oat, potato, common bean, spirulina, and mussel are reported to possess beneficial effects on redox balance and metabolic disorders (obesity, diabetes, hypertension, and inflammatory bowel diseases (IBD)). Peptide length, sequence, and composition significantly affected the bioactive properties of dietary BPs. Numerous studies have demonstrated that various dietary protein-derived BPs exhibited biological activities through the modulation of various molecular mechanisms and signaling pathways, including Kelch-like ECH-associated protein 1/nuclear factor erythroid 2-related factor 2/antioxidant response element in oxidative stress; peroxisome proliferator-activated-γ, CCAAT/enhancer-binding protein-α, and sterol regulatory element binding protein 1 in obesity; insulin receptor substrate-1/phosphatidylinositol 3-kinase/protein kinase B and AMP-activated protein kinase in diabetes; angiotensin-converting enzyme inhibition in hypertension; and mitogen-activated protein kinase and nuclear factor-kappa B in IBD. This review focuses on the action of molecular mechanisms of dietary BPs and provides novel insights in the maintenance of redox balance and metabolic diseases of human.

Abstract
This study explores the inhibitory properties of camel whey protein hydrolysates (CWPH) toward α-amylase (AAM) and α-glucosidase (AG). A general full factorial design (3 × 3) was applied to study the effect of temperature (30, 37, and 45°C), time (120, 240, and 360 min), and enzyme (pepsin) concentration (E%; 0.5, 1, and 2%). The results showed that maximum degree of hydrolysis was obtained when hydrolysis was carried out at higher temperature (45°C; P < 0.05), compared with lower temperatures of 30 and 37°C. Electrophoretic pattern displays degradation of all protein bands upon hydrolysis by pepsin at various hydrolysis conditions applied. All the 27 CWPH generated showed significant AAM and AG inhibitory potential as indicated by their lower IC50 values (mg/mL) compared with intact whey proteins. In total 196 peptides were identified from selected hydrolysates and 15 potential peptides (PepSite score > 0.8; http://pepsite2.russelllab.org/) were explored via in silico approach. Novel peptides PAGNFLMNGLMHR, PAVACCLPPLPCHM, MLPLMLPFTMGY, and PAGNFLPPVAAAPVM were identified as potential inhibitors for both AAM and AG due to their high number of binding sites and highest binding probability toward the target enzymes. CCGM and MFE, as well as FCCLGPVPP were identified as AG and AAM inhibitory peptides, respectively. This is the first study that reports novel AG and AAM inhibitory peptides from camel whey proteins. The future direction for this research involves synthesis of these potential AG and AAM inhibitory peptides in a pure form and investigate their antidiabetic properties in the in vitro, as well as in vivo models. Thus, CWPH can be considered for potential applications in glycaemic regulation.

Abstract
Hyperglycemia-induced oxidative stress can cause liver damage in diabetes, and protein hydrolysates with antidiabetic and antioxidant properties are emerging as a potential therapy. In this study, protective effects of casein hydrolysates against live oxidative damage in streptozotocin/high-fat-induced diabetic rats were studied and potentially bioactive peptides were explored by an integrated approach of differential peptide and in silico analysis. Results showed that different casein hydrolysates significantly alleviated liver oxidative damage (p < 0.05) via different mechanisms. Particularly, casein hydrolyzed by a papain-flavourzyme combination (P-FCH) treatment significantly improved liver antioxidant enzyme activities by enhancing nuclear factor erythroid 2-related factor 2 (Nrf2) transcription (p < 0.05). Furthermore, 18 peptides were screened as potential bioactive peptides by analyzing differential peptides among different hydrolysates combined with in silico prediction. Among them, the dipeptide WM might directly inhibit the Kelch-like ECH-associated protein 1 (Keap1)-Nrf2 interaction as potential Nrf2 activators. These results suggested that P-FCH might be an alternative way to treat liver damage in diabetes.

Abstract
Protein-polysaccharide interactions have been a focus of scientific attention. This study aimed to improve the antioxidant and hepatoprotective effects of buffalo total milk proteins and whey protein hydrolysate (WPH) through noncovalent interactions with Psyllium husk (ispaghula) mucilage (PHM) and Nabq mucilage (NabM). Chemical composition, phenolic content, and antioxidant activities of milk protein-mucilage complexes were explored. The effects of resulting complexes on liver function, hyperlipidemia, and histopathology of the liver in rats fed high-fat diet (HFD) were investigated. The results showed that the complexes exerted significant effect on normalizing tested parameters; WPH-NabM had the most significantly decreased level of malondialdehyde content and the liver histopathological examination proved an improvement in all groups fed with these complexes. These complexes can be used as functional protection elements against the nonalcoholic fatty liver disease. PRACTICAL APPLICATIONS: PHM, NabM, and their complexes with milk proteins were proved to improve liver function, enhancing most of its measurable parameters and also diminishing the risk of cardiovascular disease. Mice with HFD achieved better health circumstances by combining these ingredients in their diet. Knowing how much these diseases proliferate in the western world and its correlation with high-fat consumption and modern lifestyle, its conjugation with PHM/NabM-MP complexes may reduce the negative impact of unhealthy food intake and, on some parameters, even improving the whole liver function. For that reason, the present study supports and pushes forward the dissemination and consumption of ispaghula or Nabq (the polysaccharides sources) or supplements originating from them. Although many interactions concerning milk proteins have already been analyzed, our study also proposes the interaction with bioactive polysaccharides as useful, opening a field of research aimed at the better application of milk proteins.

J Dairy Sci 2019; 103:1884-1893. [PMID: 31837790 DOI: 10.3168/jds.2019-17355] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2019] [Accepted: 10/11/2019] [Indexed: 01/10/2023]
Abstract
Buffalo skim milk retentate was hydrolyzed with papain for 4 h (enzyme:substrate, 1:200), resulting in a retentate hydrolysate (RH) with a degree of hydrolysis of 23%. We then investigated the potential hepatoprotective activity of RH at 250 and 500 mg/kg of body weight per day on carbon tetrachloride (CCl4)-induced oxidative stress in albino rats. Liver biomarkers (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase), kidney biomarkers (urea, creatinine), and serum lipid profile (total lipids and triglycerides) were measured, in addition to histopathological status. Injection of CCl4 significantly increased all liver and kidney biomarkers compared with the negative control. In contrast, CCl4 injection significantly reduced hepatic antioxidant enzyme activities; that is, glutathione peroxidase and superoxide dismutase. Oral administration of RH for 28 d effectively maintained a physiologically normal range of liver and kidney biomarkers compared with the positive control. Furthermore, RH administration significantly increased activities of glutathione peroxidase and superoxide dismutase. Histopathological sections of CCl4-stressed rats treated with RH were different from that of the positive control and were similar to those of the negative control, in a concentration-dependent manner. Our results demonstrated the antihepatotoxic activities of buffalo milk RH and demonstrated that the higher RH concentration (500 mg/kg of body weight per day) could maintain the healthy biological status of the CCl4-injected rats.

[PMID: 31145727 PMCID: PMC6542520 DOI: 10.1371/journal.pone.0216816] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2018] [Accepted: 04/29/2019] [Indexed: 11/25/2022] Open
Abstract
The high heat and mass transfer, and controlled mechanoenergy, in angled vortex fluidics has been applied in chemical and material sciences and allied fields, but its utility in food processing remains largely unexplored. Herein we report three models of food processing incorporating such vortex fluidics, including enzymatic hydrolysis, raw milk pasteurization and encapsulation. The processing times of enzymatic hydrolysis was reduced from about 2–3 hours to 20 minutes, with the processing time of raw milk pasteurization reduced from 30 to 10 minutes, and an encapsulated particle size reduced approximately 10-fold, from micro meters to hundreds of nanometers. These findings highlight exciting possibilities, in exploiting the value of vortex fluidic mediated processing in the food industry.

Birth Defects Res 2018; 110:1001-1015. [PMID: 29851303 DOI: 10.1002/bdr2.1341] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2017] [Revised: 03/05/2018] [Accepted: 03/19/2018] [Indexed: 11/11/2022]
Abstract
BACKGROUND Hyperglycemia-related oxidative stress and hypoxia are important mechanisms responsible for diabetes-induced embryopathy and other complications. High sucrose low copper diet (HSD), but not regular diet (RD), induces type 2 diabetes in the inbred Cohen diabetic sensitive (CDs) rats but not in the Sabra control rats. We recently demonstrated long-term changes of DNA methylation and gene expression in various groups of genes, including genes involved in oxidant-antioxidant activity in the liver of 2-4-week-old CDs offspring of diabetic dams. We now studied the postnatal effects of diabetes and/or HSD on several liver metabolic parameters in these offspring. METHODS we studied lipid peroxidation, activity of the antioxidants enzymes superoxide dismutase (SOD) and Catalase (CAT). By immunohistochemistry: protein oxidation by nitrotyrosine staining, hypoxia inducing factor1α (HIF1α), apoptosis [caspase 3, bcl-2-like protein (BAX)], proliferation [proliferating cell nuclear antigen (PCNA)] and NF-κB. RESULTS In the Sabra rats fed HSD only few, early and transitional changes were observed in lipid peroxidation, SOD and CAT activity. In the CDs fed HSD more significant changes in lipid and protein oxidation, HIF1α, apoptosis and proliferation were observed, persisting for longer. CONCLUSIONS The changes in the Sabra rats HSD were attributed to the pro-oxidant effects of the diet and those in the diabetic CDs to the HSD and maternal diabetes. In light of the DNA methylation changes in the liver of the CDs HSD, we presume that changes in gene expression are responsible for our findings, and that similar changes may lead to the metabolic syndrome at adulthood.
