Industrial-scale feasibility for textile wastewater treatment via Photocatalysis-adsorption technology using black sand and UV lamp.

Dye-contaminated wastewater is a major environmental problem that requires effective and affordable treatment methods. This study investigates an innovative approach using black sand filtration assisted by UV light to remove methylene blue (MB) dye from wastewater. The motivation is to develop a sustainable low-cost wastewater treatment technology. Black sand's composition of iron oxide and other metal oxides enables the adsorption and photocatalytic degradation of dyes. The effects of operating parameters, including pH, bed height, flow rate, and initial MB concentration, were examined using a fixed-bed column system. The maximum adsorption capacity was 562.43 mg g-1 at optimal pH 10, 15 cm bed height, 50 ppm MB, and 53.33 mL min-1 flow rate. Mathematical models effectively described the experimental breakthrough curves. For real textile wastewater, black sand with a UV lamp removed 50.40% COD, 73.68% TDS, 43.82% TSS, and 98.57% conductivity, significantly outperforming filtration without UV assistance. Characterization via XRD, XRF, FTIR, zeta potential, and SEM revealed black sand's photocatalytic properties and mechanism of MB adsorption. The findings demonstrate black sand filtration plus UV irradiation as a feasible, sustainable technology for removing dyes and organics from wastewater. This method has promise for the scale-up treatment of textiles and other industrial effluents.

Molecular docking and in vivo protective effects of okra (Abelmoschus esculentus) against metabolic dysfunction in high-fat, high-sodium diet-fed rats.

Okra pods (Abelmoschus esculentus L. Moench) have been used as a functional vegetable as they contain polysaccharides, flavonoids, and other bioactive molecules that protect the body from several chronic diseases. The purpose of this study was to look at the involvement of okra constituents (mucilage and flesh) in the prevention of metabolic dysfunctions induced in a rat model by a high-fat, high-salt (HF/NaCl) diet. Okra mucilage was extracted using an ultrasonic method, freeze-dried, characterized using Fourier transform infrared (FTIR) and scanning electron microscopy (SEM), and tested for swelling ratio and radical scavenging activity. Okra flesh (skin and seeds) was separated from pods; characterized using SEM; and tested for dietary fiber content, phenolic profile, and radical scavenging activity. The significance of okra bioactive compounds in inhibiting human salivary amylase, glutamine : fructose-6-phosphate amidotransferase (GFAT), tumor necrosis factor-alpha (TNF-α), and C-reactive protein (CRP) was investigated using molecular docking. Rats were fed an HF/NaCl diet and orally treated daily with freeze-dried okra mucilage or flesh (100 mg per kg body weight) for 8 weeks. Glucose, insulin, inflammatory indicators (CRP, TNF-α, and interleukin 6), oxidative markers (red blood cell lipid peroxidation, glutathione peroxidase, nitric oxide, and superoxide dismutase), lipid profile, estradiol, feces lipids as well as femur and urine calcium were measured. The molecular docking findings showed the interaction of quercetin and chlorogenic acid, which are the most abundant phenolic compounds in okra pods, with the studied proteins, which gives an indication of the mechanism of okra's anti-diabetic, anti-oxidant, and anti-inflammatory effects. Okra mucilage and flesh significantly reduced glucose, insulin, cholesterol, lipid peroxidation, CRP, TNF-α, IL-6, and urine calcium levels while significantly increasing feces lipid and femur calcium levels. The findings suggested that okra mucilage and flesh seem to be promising candidates for protection against metabolic dysfunction.

Development of a functional cake with probiotics and micro-encapsulated essential oils: Evaluation of nutritional properties, liver protection, and immune boosting.

This study used probiotics and micro-encapsulated clove and cinnamon oils to develop a functional cream-stuffed cake based on sweet potatoes flour and rice flour instead of wheat flour. The cake was evaluated for its physical, chemical, and sensory properties and its antioxidant capacity. The protective effect of the cake against liver injury and immunosuppression induced by thioacetamide injection in male rats was also evaluated. The study found that eugenol and cinnamaldehyde were the majority of volatile compounds in the essential oils used in the cake, with values of 78.73 % and 81.57 %, respectively, as determined by GC-MS analysis. The viable counts of added probiotics in the cake ranged from 13.15 to 11.21 log CFU/g and were still above the threshold for health benefits. The cake had an increased dietary fiber and protein content while containing a low-fat percentage compared to a commercial cake sample. The innovative cake also contained higher levels of water-soluble and fat-soluble vitamins and minerals such as iron, calcium, potassium, and zinc. The antioxidant capacity of the cake was evaluated, and it was found to contain 1827.23 mg GAE/100 g of total phenols and 97.13 mg QE/100 g of flavonoids. The cake was also found to have antioxidant activity and was effective in protecting the liver from oxidative stress and inflammation and reducing immunodeficiency associated with liver damage.

Impact of serum IL 10 on prediction of early allograft rejection in liver transplantation.

Tissue transplantation is the preferred treatment for end organ failure such as heart, lung, kidney, and liver. The immune system recognizes the transplant as non self if the donor and recipient are not genetically identical. Multiple cytokines are involved in this process; however, little is known about their predictive role in rejection. Interleukin 10 (IL-10) which exhibits anti-inflammatory activity could be used as early predictor of acute rejection. The current study intended to determine any potential relationship between acute allograft rejection and blood IL-10 levels in liver transplant (LT) recipients. This study included 45 patients with cirrhotic liver diseases planned for transplantation. Patients were followed up for 2 months and then divided into two groups: patients who developed early acute rejection and those who did not develop rejection (as controls). Of the study patients, 38 (84.4%) patients did not develop rejection and 7 (15.6%) patients developed rejection. The levels of IL-10 did not change during rejection of the LT. In conclusion, the findings of the current study indicated no relation of IL-10 levels during LT rejection.

Ameliorative effects of vitamins-loaded flavoured nanophytosomes fortified with star anise volatile oil against CsA-Induced liver and kidney injury in rats: Application in functional ice cream.

This study investigated the effect of flavoured nanophytosomes loaded with vitamins A, E, D, B complex, folic acid, and C, as well as zinc on the immunosuppressive cyclosporin A (CsA)-induced liver and kidney injury in male rats. The vitamins flavoured nanophytosomes (VFnPs) were characterized in terms of particle size, zeta potential, encapsulation efficiency. Ice cream was flavoured with star anise volatile oil to mask the VFnPs' flavour and unacceptable taste. The study found that treatment with CsA alone resulted in increased (P > 0.05) levels of creatinine, urea, and MDA, as well as the activities of AST and ALT, while the levels of SOD, CAT, GST, proteins, CD4, INF-ᵧ, IL-6, IL-1ß, and TLR4 decreased (P > 0.05). However, the group that received CsA simultaneously with VFnPs showed a significant (P > 0.05) decrease in the levels of creatinine, urea, and MDA, as well as the activities of AST and ALT, and increased (P > 0.05) levels of SOD, CAT, GST, proteins, CD4, INF-ᵧ, IL-6, IL-1ß, and TLR4. The increase in the ratio of VFnPs had little effect on the physiochemical and sensory evaluation of the ice cream. Finally, the study suggests that VFnPs could potentially protect against CsA-induced liver and kidney injury and serve as a promising natural therapy for treating such conditions.

Protective effect of tomato pomace extract encapsulated in combination with probiotics against indomethacin induced enterocolitis.

Tomato pomace (TP), an antioxidant-rich byproduct, may be suitable for noble applications. The regulation of ROS generation and the anti-inflammatory response can help to prevent ulceration. The purpose of this study was to examine TP for antioxidants, in silico anti-inflammatory properties, and its potential to protect against ulceration and erosion triggered by indomethacin. Tomato pomace extract (TPE) was encapsulated either alone or with probiotics to maximize its potential effect. These microcapsules were investigated in indomethacin-treated rats. TPE demonstrated antioxidant activity as well as high levels of carotenoids (15 mg/g extract) and polyphenols. Because of their binding affinity as well as hydrophobic and hydrogen bond interactions with the active sites of TNF-α and IL-1ß inflammatory cytokines, ellagic acid and rutin may be implicated in the anti-inflammatory effect of TPE, according to the docking study. TPE microcapsules, either alone or in combination with probiotics, demonstrated a protective effect against enterocolitis by reducing oxidative stress and inflammation, as evidenced by the decrease in stomach and intestinal MDA, NO, IL-1ß, IL-6, and TNF-α levels and the increase in CAT, SOD, and GSH activities. The produced microcapsules are suggested to be promising candidates for protection against gastric ulcers and erosion.

The relationship between ovarian hormones and mast cell distribution in the ovaries of dromedary camel (Camelus dromedaries) during the follicular wave.

Background and Aim: Mast cells (MCs) play an essential role in regulating tissue homeostasis through various non-allergic immune reactions. This study aimed to describe the salient features of MCs during different phases of the estrous cycle and evaluate the relationship between ovarian hormones and the presence of MCs in camel ovaries. Materials and Methods: Genital tracts (n = 28) of healthy, non-pregnant camels were collected from a local slaughterhouse. The follicular wave stage was determined according to structures on the ovaries using an ultrasound device. Stages were classified as "growing" (n = 12, FØ = 0.3-0.8 cm), "mature" (n = 9, FØ = 0.9-2.2 cm), or "regression" phase (n = 7, FØ >2.5). Blood samples were collected at slaughter to determine serum estradiol-17ß and progesterone levels using an immunoassay. Safranin-O, periodic acid/Schiff, alcian blue, or methylene blue stains were used to detect MCs. Results: Follicular numbers at the growing, mature, and regression phases were determined to be 36, 14, and 7 follicles, respectively. Mast cells were widely but sparsely distributed within the ovarian tissue (9.3 MCs in the growing phase, 10.7 in the mature phase, and 7.0 in the regression phase). Typical histological features of MCs were observed in ovarian stromal tissue. Some MCs were found in the interstitial tissue, either near the follicular wall or the interstitial gland. Mast cells were present at a higher density during the mature phase than in the growing and regression phases in the ovarian matrix. A significantly reduced presence of MCs was found in the regression phase than in both the growing and mature phases (p < 0.05). A very strong positive correlation was observed between serum estradiol-17ß concentrations and MC density in the ovaries (r = 0.9; p < 0.001). In addition, a strong negative correlation (r = -0.65; p = 0.03) was observed between the presence of MCs and serum progesterone concentrations. Conclusion: These findings suggest that the follicular wave phase and the associated hormonal concentration induce changes in the number of MCs in the camel ovary.

Characterization of stirred yoghurt enriched with probiotics and beetroot and its therapeutic potential in experimental type 2 diabetes.

BACKGROUND: Type-2 diabetes is the most prevalent metabolic disease, which calls for researchers to find many natural products that are effective in fighting diabetes and its complications. METHODS: Stirred yoghurt samples were prepared, enriched with probiotics, and fortified with either 1% or 2% of the fine powder of beetroots. The chemical, physical, sensorial, and microbial properties of the yoghurt samples were studied over a 15-day storage period. The total phenolic compounds, flavonoids, antioxidant activity as well as the reducing power of the dried beetroot and the yoghurt samples were assessed.The prepared yoghurt samples were evaluated in type 2 diabetic rats. RESULTS: Fortification with beetroot led to an increase of the total phenolic compounds, antioxidant activity, and the probiotic counts in the prepared yoghurt. The intervention with the prepared yoghurt samples resulted in an increase in the number of beneficial bacteria in diabetic rats’ feces, hypoglycemic effect, and suppression in the elevation of C-reactive protein (CRP) and thyroid stimulating hormone (TSH). CONCLUSIONS: This study suggests that stirred yoghurt enriched with probiotics and fortified with beetroot have therapeutic potential for type 2 diabetes.

Investigations on the vaginal temperature, cycle stages, and steroid hormone concentrations during the breeding season in camels (Camelus dromedarius).

BACKGROUND AND AIM: Estrus detection plays a crucial role in the success of animal reproduction. It was previously reported that body temperature changes during estrus. This study aimed to investigate the relationship between vaginal temperatures (VTs) measured by a data logger, ovarian activity, and hormonal cyclic changes in camels. MATERIALS AND METHODS: Six mature, healthy, non-pregnant dromedary, and 10-12-year-old camels were included in the study. The ovarian activity was monitored with ultrasonography, and estrus behavior was evaluated using an active and virile male camel. Animals were inserted with a blank controlled internal drug release device attached with an intravaginal data logger. Every hour, the ambient temperature was recorded by another data logger. Blood samples were collected, and sera were used to measure estradiol and progesterone levels. RESULTS: The whole follicular cycle lasted 25.41±1.36 days, and the maximum sizes of the dominant follicle in the first and second follicular waves were 1.63±0.27 cm and 1.94±0.42 cm, respectively. There was a significant positive correlation between the follicular diameter and estradiol-17b level (p<0.01, r=0.397). There was no correlation between the follicular diameter and progesterone level (p>0.05, r=0.038), which remained low during the whole period of the experiment. The mean daily VT was significantly correlated with the diameter of the dominant follicle (1.7-2.2 cm, p<0.01, r=0.52). CONCLUSION: Measurement of VT will improve the accuracy of estrus prediction. Further studies are recommended to validate VT in camel reproduction.

A study of leptin and its gene 2548 G/A Rs7799039 single-nucleotide polymorphisms in Egyptian children: A single-center experience.

BACKGROUND/OBJECTIVES: The pathophysiology of obesity is multifactorial, including genetic and environmental factors. Previous studies had highlighted the association of the leptin gene/receptor with obesity. We aimed to study the leptin gene rs7799039 single nucleotide polymorphism (SNP) in children, and its association with the children's characteristics. METHODS: A cross-sectional analytic study that included 143 children with obesity (cases) and a comparable group of 86 lean children as controls. The anthropometric measures, blood pressure, and biochemical testing were done for all participants. The real-time polymerase chain reaction was used to detect rs7799039 SNP variant alleles and ELISA for leptin level assessment. RESULTS: The distribution of rs7799039 SNPs genotypes GG/GA/AA was comparable between both groups. Testing children regardless of their body mass index showed that the abnormalities in blood pressure, lipids values, insulin resistance, and hepatic insulin sensitivity were significantly associated with increased leptin levels. Among cases, the abnormal metabolic status was associated with higher leptin levels. CONCLUSIONS: The genotype' distribution of leptin gene rs7799039 SNP was similar in both children with obesity and those with normal-weight. The high blood pressure, abnormal lipid profile, and metabolic disturbances, were significantly associated with higher leptin levels and not with leptin gene rs7799039 SNP.

Reduction of sulfur oxides emissions via adsorptive desulfurization of transportation fuels using novel silica-based adsorbent.

Transportation fuels with high sulfur content are one of the primary contributors to air pollution because they emit massive quantities of sulfur oxides upon combustion. The emitted sulfur oxides undoubtedly contribute to global warming and climate change. Therefore, they should be minimized. The current study accurately describes a novel and direct synthetic pathway for the incorporation of sulfonic acid groups (-SO3H) into mesoporous silica surface. The structure of the prepared materials was confirmed using FTIR, SEM, BET, SA-XRD, TEM, and TGA techniques. The batch adsorption technique was used to carefully evaluate the adsorption efficiency of the prepared adsorbent towards dibenzothiophene (DBT). At optimal adsorption conditions, a maximum adsorption capacity of 75-mg DBT/g adsorbent was achieved. The desulfurization process fitted well to Langmuir and pseudo-second-order models. In addition, the desulfurization process was found to be a spontaneous and exothermic process. As a final point, the practical applicability of the prepared adsorbent, as well as its reusability, was properly investigated, and the results were promising.

Association of Polymorphism in Survivin Gene and the Risk of Liver Cancer Resulting from Hepatitis C Virus Among Egyptian Patients.

BACKGROUND: This study aims to investigate the relation between Survivin gene polymorphisms and the risk of Hepatocellular carcinoma (HCC) resulting from hepatitis C infection among the Egyptian population. METHODS: This prospective study was conducted on 164 patients, 57 patients were diagnosed with hepatitis C, where 57 were diagnosed with HCC in addition to 50 healthy volunteers as controls. Genotyping for Survivin rs1042489 and rs8073069 single nucleotide polymorphisms was carried out by the allelic discrimination Real-Time Polymerase Chain Reaction Single Nucleotide Polymorphisms genotyping technology. RESULTS: The results of Survivin rs1042489 polymorphism revealed that the TC and CC genotypes were significantly different between hepatocellular carcinoma patients (OR=15.5, 95%CI: 3.299-72.825,P<0.001), and controls (OR=44, 95%CI: 8.025-241.254, P<0.001). Furthermore, CC genotype was significantly different between cirrhotic and hepatocellular carcinoma patients (OR=19.2, 95%CI: 3.097-119.049, P=0.002). Moreover, the TC genotype shows a significant difference between controls and cirrhotic patients (OR=5.5, 95%CI: 2.111-14.328, P<0.001). However, when comparing TT genotypes, CC+TC genotypes results showed a significant association with increasing the risk of cirrhosis and hepatocellular carcinoma (OR=4.812, 95%CI: 1.893-12.233, P=0.001), (OR=21.607, 95%CI: 4.738-98.532, P<0.01), respectively. On the other hand, there was no significant difference among all studied groups for all genotypes regarding Survivin rs8073069. Also, the CC+GC genotype showed no significant association with increased risk of hepatocellular carcinoma (P=0.999) compared with the GG genotypes. CONCLUSION: The study indicates that functional Survivin rs1042489 polymorphism may contribute to the risk of hepatocellular carcinoma while Survivin rs8073069 polymorphism has no significant association with increased risk of hepatocellular carcinoma among the studied groups.

A green synthesized recyclable ZnO/MIL-101(Fe) for Rhodamine B dye removal via adsorption and photo-degradation under UV and visible light irradiation.

Metal-organic frameworks (MOFs) have recently debuted as participants and solid supports in catalysts for environmental application in water treatment. Visible light active nanocomposites; ZnO/MIL-101(Fe); were synthesized via a hydrothermal method by loading ZnO; prepared by a green method; on a porous MIL-101(Fe) to be used as a heterogeneous catalyst for Rhodamine B dye (RhB) degradation as a model pollutant. The effect of adding acetic acid during the preparation of MIL-101(Fe) was studied; [A] used for the samples prepared by acetic acid. The prepared catalysts were characterized by XPS, XRD, zeta potential, TGA, FTIR, N2 adsorption-desorption measurements, SEM, EDX, elemental mapping, TEM, and UV-VIS diffuse reflectance spectroscopy. The loading of ZnO on MIL-101(Fe) decreased the band gap from 3.2 eV for ZnO to be 2.85 eV for ZnO/MIL-101(Fe)[A], this low band gap explaining the obtained high activity under visible light irradiation. The mechanism of the photocatalytic degradation of RhB was investigated by introducing different scavengers to compete for the possible reactive species involved in the degradation process. The trapping experiments indicated that h+ and •OH have a vital role in the RhB degradation. The reusability of MIL-101(Fe) was also investigated after three runs. Thus, the synthesized ZnO/MIL-101(Fe)[A] could be used as an alternative catalyst for the photocatalytic degradation of coloured wastewater as it can successfully degrade 97.1% of Rhodamine B (10 mg/L) with high reaction rate (k = 0.0339 min-1) under visible light irradiation for 300 min using 0.5 g/L of the catalyst. The as-prepared ZnO/MIL-101(Fe) and ZnO/MIL-101(Fe)[A] have competitive photocatalytic dye degradation activity.

Fortified vegetarian milk for prevention of metabolic syndrome in rats: impact on hepatic and vascular complications.

Metabolic syndrome (MetS) is characterized as a gathering of various metabolic disorders, for example, hyperglycemia, dyslipidemia, and obesity. The present research was conducted to prepare fortified almond milk as functional beverages and evaluate their protective effect against MetS and associated hepatic and vascular complications. Three beverages (I, II, and III) were prepared by fortification almond milk with carrot juice or powder of quinoa seeds and carrot juice or oat powder and banana juice. The sensory attributes, physicochemical properties, bioactive compounds (total phenolic, beta-carotene, tocopherols) and B-complex vitamins were determined in the beverages. In-vitro antioxidant activity of the beverages was assessed. MetS was induced in rats via feeding on high-fat high-fructose diet (HFHF). The biochemical (lipid profile, oxidative stress, liver, and kidney functions), nutritional and histopathological parameters were assessed in rats. The beverage I recorded the highest sensory attributes' scores. The physicochemical properties of the beverages revealed that acidity and viscosity of all beverages ranged from 4.55 to 4.88 and from 40 to 59, respectively. The beverage I showed the highest content of alpha-tocopherol (14.994 µg/g) and beta-carotene (104.541 µg/g), while the beverage II showed the highest content of gamma-tocopherol (0.557 µg/g), folic acid (0.806 µg/g), and total phenols (147.43 µg GAE/g). The results of animals revealed that the beverage II was the most promising in attenuation levels of total cholesterol, triglycerides, low-density lipoprotein cholesterol, malondialdehyde, and tumor necrosis factor-alpha. Also, the beverage II was the superior in the protection of the liver and heart tissues as reflected by the histopathological examination findings. So, it can be concluded that the newly prepared almond milk with quinoa seeds and carrot juice could be used as an effective functional beverage for the prevention of MetS and its complications.

Anti-inflammatory potential of chia seeds oil and mucilage against adjuvant-induced arthritis in obese and non-obese rats.

Background Natural anti-inflammatory nutraceuticals may be useful in suppressing the incessant aggravation of rheumatoid arthritis. Chia seeds as a natural source of antioxidants help prevent several oxidative stress-mediated diseases. The current study was focused on arthritis combined with obesity and evaluated the validation of oil and mucilage extracted from chia seeds as anti-inflammatory nutraceuticals in obese and non-obese adjuvant arthritic rat model. Methods Chia seeds oil was extracted by pressing method, whereas the mucilage was extracted using water (50 °C for 30 min). Oil and freeze-dried mucilage were tested for their anti-inflammatory effects using 48 male Sprague-Dawley rats. Obesity was developed in rats after 8 weeks of feeding on high-fat high-sucrose diet; on the first day of the ninth week, chia seeds oil and mucilage were administrated for 21 days, and arthritis was induced either in obese or non-obese rats via the injection with Freund's complete adjuvant. Swelling of the paw was then measured. Plasma tumor necrosis factor (TNF-α), lipid profile, liver and kidney functions, serum lipid peroxidation, and erythrocyte catalase activity were determined. Results Results emphasized that arthritis with obesity resulted in the elevation of the swelling of the paw, TNF-α, dyslipidemia, and oxidative stress. Chia seeds oil and mucilage, more promisingly the oil, attenuated TNF-α and the swelling of the paw, improved lipid profile, and diminished the oxidative stress both in obese and non-obese arthritic rats. Conclusions Results showed that chia seeds oil and mucilage exhibited anti-inflammatory effects against adjuvant-induced arthritis in obese and non-obese rats.

Efficiency of newly formulated functional instant soup mixtures as dietary supplements for elderly.

Healthy diet for elderly not only provides them with their needs from macro and micronutrients but also help preventing and treating age-related disorders including non-communicable diseases. So, the present study established to evaluate physical, sensory, chemical and biological characteristics of newly formulated functional instant soup mixtures as dietary supplements for elderly. Lyophilized chickpea, some vegetables and some by-products (at 5% and 10%) were incorporated in the preparation of two instant soup mixtures. The biological effects of the mixtures were studied using a geriatric animal model. The results revealed a reasonable acceptance of the two mixtures even after storage period (4 months) in addition to their contents from protein, fat, crude fiber and carbohydrates (16.62, 6.20, 6.60 and 65.89%, respectively in mixture I; 16.89, 6.30, 6.30 and 54.16%, respectively in mixture II). Mixture II was more promised in flavonoids content and scavenging radical activity than mixture I. Feeding the geriatric rats on the two mixtures did not produce any change in either liver or kidney functions and suggested the ability of these mixtures to prevent the hyperglycemia and hyperlipidemia and improve bone health. A slight decrease in brain lipid peroxidation, although not statistically significant, of rats has been observed upon feeding on these mixtures. Also, the two mixtures increased feces weight of rats which indicates to the beneficial effects of these mixtures in prevention of constipation. In conclusion the formulated instant soup mixtures with high acceptability and antioxidant activity can provide elderly people with high percent of their requirements from macro and micronutrients.

Hepatorenal protective effect of flaxseed protein isolate incorporated in lemon juice against lead toxicity in rats.

Finding renal and hepatoprotective agents preferably with antioxidant activities against environmental pollutants especially lead which can adversely affect liver and kidney is a great demand. In the current study, flaxseed protein isolate (FPI) was extracted from defatted flaxseed meal. Amino acids profile, antioxidant capacity and solubility of the extracted FPI were determined. The solubility of FPI in the acidic media was exploited in preparation of lemon juice with FPI. Twenty four male rats were assigned to four groups; normal control, lead intoxicated (oral daily dose of 60 mg/kg b.w. in distilled water for four weeks), lead intoxicated and orally administrated with daily dose equal 1 ml of lemon juice as well as lead intoxicated and orally administered with FPI (daily dose equal 100 mg/kg) in 1 ml of lemon juice. The oral administration of FPI incorporated in lemon juice suppressed the elevation in kidney functions, lipid peroxidation of kidney tissues, urinary protein and creatinine as well as liver functions caused by lead intoxication. Additionally, lemon juice with FPI combated the reduction of GSH of kidney tissues. It was revealed also that lemon juice without FPI suppressed the elevation in kidney and liver functions caused by lead. It can be concluded that flaxseed protein isolate is a good source of protein with potent antioxidant activity. Additionally, lemon juice and FPI are considered protective sources of kidney and liver against lead toxicity.

Hypoglycemic, hypolipidemic and antioxidant effects of green sprouts juice and functional dairy micronutrients against streptozotocin-induced oxidative stress and diabetes in rats.

Hyperglycemia, the mark normal for diabetes and associated disorders are the main goals of natural diabetes therapies. In this context, the present research was designed to study the effects of fenugreek sprouts juice (FS), barley sprouts juice (BS), cell-free probiotic extract (cell-free PE), whey protein hydrolysate (WPH) and their mixture on diabetic rats. Free radical scavenging activity, total phenolic contents (TPC) and total flavonoid contents (TFC) of each item mentioned were determined. Diabetes was induced through the injection of male rats with a single intraperitoneal dose (45 mg/kg) of streptozotocin. After the development of diabetes, diabetic rats were orally administered daily with 1ml of with fenugreek sprouts juice, barley sprouts juice, cell-free probiotic extract, whey protein hydrolysate or their mixture until the end of the study period (45 day). Oral administration of fenugreek sprouts juice, barley sprouts juice, cell-free probiotic extract, whey protein hydrolysate and their mixture to diabetic rats significantly reduced fasting blood glucose levels and improved the lipid profile. All the studied items limit the reductions of haemoglobin concentrations and plasma α-amylase activities. Also all the studied items suppressed the elevation of malondialdehyde values and the reduction of catalase activities. Histopathological investigation of pancreas, liver and kidneys of the diabetic rats showed histological alterations. On the other hand, supplementations with the tested materials lead to relieving these injuries. Results revealed that fenugreek sprouts juice, barley sprouts juice, cell-free probiotic extract, whey protein hydrolysate and their mixture had promising effects towards hyperglycemia and associated disorders.

In vitro Anticancer Activity of Quinoa and Safflower Seeds and Their Preventive Effects on Non-alcoholic Fatty Liver.

BACKGROUND AND OBJECTIVE: Non-alcoholic fatty liver disease (NAFLD) is not only the most common cause of liver diseases in humans but also it may complicate and become a risk factor for liver cancer. The present work aimed to evaluate the anticancer activity (in vitro) of quinoa and safflower seeds powder and their beneficial effects against NAFLD (in vivo). MATERIALS AND METHODS: Proximate analysis, fatty acids profile, total phenolic and phytic acid of quinoa and safflower seeds were assessed. Also their anticancer activities (in vitro) against liver cancer were evaluated. The preventive effect of both seeds on NAFLD was evaluated using twenty four male rats. NAFLD was induced in rats by high fructose diet (HFD) for 4 weeks. The effects of HFD and HFD supplemented with 20% quinoa or safflower powder on plasma and liver lipids, lipid peroxidation, total protein, albumin as well as liver and kidney functions were determined. RESULTS: Quinoa seeds powder was promising in cytotoxicity against hepatocarcinoma cell line HEPG2 (IC50 was 14.6 µg). Feeding rats on HFD produced dyslipidemia and significant increase in liver functions and lipid peroxidation with significant elevation in liver triglycerides and total cholesterol. Quinoa and safflower seeds powder produced improvement in the biochemical parameters with different degrees. CONCLUSION: Quinoa and safflower seeds powder possessed cytotoxicity against hepatocarcinoma cell line HEPG2 and afford hepato-protection against NAFLD.
