Cucurbita pepo L. is one of the most important crops that belong to the Cucurbitaceae family, an herbaceous, perennial, and polymorphic vegetable that grows also in tropical conditions. Pumpkin fruit contains large amounts of vitamins, minerals, and biologically active substances. The pumpkin seed oil contains high amounts of unsaturated fatty acids and is effective in treating different health conditions. Nevertheless, on the other hand, there have been reports that pumpkin tends to collect small amounts of nitrate or heavy metals. Therefore, our study aimed to investigate the effect of organic matter (humic acid) on the germination and activity of antioxidant enzymes, glycosylate cycle enzymes, and utilization of lipid and protein reserves of pumpkin seeds under cadmium stress conditions.

For thousands of years, medicinal plants have played a pivotal role in maintaining human health and improving the quality of human life. This study was designed to analyze the analgesic, anti-inflammatory, and antibacterial potentials of a hydro-methanolic extract of Cucurbita moschata flowers, along with qualitative and quantitative phytochemical screening. The anti-inflammatory effect was tested using the in vitro membrane stabilizing method for human red blood cells (HRBC), the analgesic effect was tested using the in vivo acetic acid-induced writing method, and the antibacterial effect was tested using the disc diffusion method. In silico ADME/T and molecular docking studies were performed to assess the potential of the stated phytochemicals against Cyclooxygenase-II enzyme. Phytochemical screening confirmed the presence of flavonoids, alkaloids, glycosides, tannins, and carbohydrates. The flower extract demonstrated the maximum protection of human red blood cells at 1000 µg/mL, with a 65.73% reduction in hemolysis in a hypotonic solution. The extract also showed significant (p < 0.05) and dose-dependent analgesic effects at oral doses of 200 and 400 mg/kg on the tested animals. Furthermore, the flower extract exhibited potent antibacterial activity due to the disc diffusion method, which was compared with standard ciprofloxacin. In silico testing revealed that 42 phytochemicals exhibited notable pharmacokinetic properties and passed drug likeness screening tests. Among the six best-selected compounds, 3,4-dihydro-2H-pyran-2-yl)methanamine showed the highest binding affinity (−10.1) with significant non-bonding interactions with the target enzyme. In conclusion, the hydro-methanolic extract of Cucurbita moschata was found to be rich in various phytochemicals that may be associated with therapeutic potential, and this study supports the traditional use of Cucurbita moschata flowers in the management of inflammation and painful conditions.

This study aimed to investigate the use of selected pumpkin varieties as carriers of potassium iodide (KI) and potassium iodate (KIO3) at different concentrations (2.3, 0.23, and 0.023 mg/100 g). It was hypothesized that the concentrations and form of iodine fortification in pumpkins affect the antioxidant activity of pumpkins. The results showed a high recovery of the introduced iodine in all pumpkin varieties after drying, as well as high iodine stability during storage, especially for KIO3. However, statistical analysis confirmed a relationship between the forms and concentration of iodine and the ABTS cation radical and the DPPH cation radical test results. In the systems with iodine concentration at 0.023 and 0.23 mg/100 g, the antioxidant activity did not change. However, for all pumpkin varieties fortified with a KIO3 concentration at 3.9 mg/100 g (2.3 mg/100 g of iodine), a statistically significant decrease in free-radical scavenging was confirmed. Therefore, for maximum effectiveness in pumpkin’s free-radical scavenging indices, it is suggested to introduce iodine in the form of KI and KIO3, but in controlled concentrations. However, KIO3 should be added at a maximum amount of 0.39 mg/100 g.

Incorporation of pumpkin seed meal, pumpkin protein concentrate and isolate and canola protein concentrate and isolate in the production of breads was evaluated. Pumpkin seed meal and protein concentrate and canola protein concentrate and isolate can be added to wheat flour up to 18% protein concentration, while pumpkin protein isolate can be added to wheat flour up to 22% protein concentration without a detrimental effect on dough or loaf quality. Further incorporation larger than 18 and 22% protein concentration yielded dense, compact. unacceptable breads. The addition of pumpkin and canola proteins increased the protein, lysine and mineral (Ca. P, Cu, Fe and Mg) contents of the breads by 11-38%, 90-200% and 70-135%, respectively. Lysine and tyrosine were the first limiting amino acids for control breads and bread enriched with canola protein concentrate, respectively. Valine was the first limiting amino acid in preads enriched with canola protein isolate, pumpkin seed meal, pumpkin protein concentrate and isolate. The chemical scores and essential amino acid indices of breads enriched with pumpkin and canola proteins were increased by 55-80% and 14-27%, respectively, compared to chemical scores and essential amino acid indices of control breads.

To find specific risk factors of gastric cancer (GC) independent of GC family history (GCFH), 2 studies were conducted using the database of the Hospital‐based Epidemiological Research Program at Aichi Cancer Center: (i) a comparison of lifestyles between non‐cancer cases with positive and negative GCFH status and (ii) a case‐reference investigation of subjects with and without GCFH, treated separately. The first showed no significant variation of GCFH status with regard to smoking, drinking and most food habits. Multivariate analyses in the case‐referent studies revealed odds ratios (ORs) for GC associated with habitual smoking of 2.78 (95% CI 1.22–6.28) for those with and 2.74 (95% CI 1.76–4.26) for those without GCFH. In individuals with GCFH, an independently lowered OR (0.52, 95% CI 0.27–0.99) was evident for frequent consumption of raw vegetables, whereas the opposite was noted for pickled vegetables (2.39, 95% CI 1.28–4.45). No statistically significant interaction was found between GCFH and selected lifestyle items. In conclusion, our results suggest a limited influence of GCFH on risk factors for GC. Int. J.

We investigated the effect of pumpkin-seed supplementation on oxalcrystalluria and urinary composition in 20 boys age 2-7 yr from a hyperendemic area of Ubol province in Thailand. The experiment had four periods: control (before treatment), oxalate supplementation 5mg · kg−1 body wt · day−1, pumpkin-seed or orthophosphate supplementation 60 mg · kg body wt−1 · day−1, and posttreatment. Causal morning and 24-h urines were collected analyzed for crystalluria, pH, calcium, phosphorous, oxalate, creatinine, sodium, potassium, citrate glycosaminoglycans, and pyrophosphate. The results demonstrated that the longer the supplementation period of pumpkin seeds, the better were the results. Pumpkin seeds lowered calcium-oxalate crystal occurrence and calcium level but increased phosphorus, pyrophosphate, glycosaminoglycans, and potassium values in urine as compared with orthophosphate supplementation. Pumpkin seeds provide high phosphorus levels and can be used as a potential agent in lowering the risk of bladder-stone disease.

Background: Plumbum (Pb) is a heavy metal widely existed, which would affect the antioxidative enzymic system of the body, and to decrease the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), and thereby to damage liver, kidney and brain, etc. Pumpkin has wide applicable merit in preventing diabetes, against hyperlipemia, preventing cancer and eliminating heavy metal poising, etc. Objective: To investigate the changes of antioxidative enzymic system induced by Pb in mouse as well as the effect of Pumpkin Distillable Subject (PKD) on antioxidation enzymic system. Design: A randomized controlled study. Setting, participants and interventions: Our study was conducted in animal laboratory of the Faculty of Public Health of Harbin Medical University. 60 purebred male healthy Kunming mice were obtained from the Experimental Animal Center of China Pharmaceutical Biological Product Analysis Institute, which were allocated into normal control group (control group), Pb management group (Pb group) and combined management group (PKD group). Mice in control group drank normal water, mice in Pumpkin group drank water that polluted by Pb to establish Plumbism model and then provided with PKD, and mice in Pb group only drank Pb-polluted water without PKD management. All animals were executed after 4 weeks for drawing bloods and taking liver, which would be prepared into homogenate. The activities of SOD, GSH-Px as well as the content of MDA in serum and hepatic homogenate were assayed. Main outcome measures: The activities of SOD, GSH-Px as well as the content of MDA in serum and hepatic homogenate in mice of each group were assayed. Results: The serous and hepatic activities of SOD, GSH-Px in mice of PKD group were significantly higher than that of Pb group (q = 7.83, 6.01, P < 0.01), but the concentrations of MDA were significantly lower that that of Pb group (q = 6.75, 6.51, P < 0.01). The serous and hepatic activities of SOD and GSH-Px in mice of Pb group[(3 746.42 ± 669.30) μkat/L, (702.64 ± 139.36) nkat/g]were significantly lower than that[(6 242.92 ± 940.02) μkat/L, (1 098.05 ± 196.37) nkat/g] of control group (q = 7.90, 5.59, P < 0.01). Conclusion: Plumbism could induce peroxidative injury in mouse. PKD could reduce the lipid peroxidation induced by Pb and increase antioxidative ability in mice.
