Antioxidants are a wide group of chemical compounds characterized by high bioactivity. They affect human health by inhibiting the activity of reactive oxygen species. Thus, they limit their harmful effect and reduce the risk of many diseases, including cardiovascular diseases, cancers, and neurodegenerative diseases. Antioxidants are also widely used in the food industry. They prevent the occurrence of unfavourable changes in food products during storage. They inhibit fat oxidation and limit the loss of colour. For this reason, they are often added to meat products. Many diet components exhibit an antioxidative activity. A high antioxidative capacity is attributed to fruit, vegetables, spices, herbs, tea, and red wine. So far, the antioxidative properties of various plant materials have been tested. However, the antioxidative activity of some products has not been thoroughly investigated yet. To date, there have been only a few studies on the antioxidative activity of the pumpkin, including pumpkin seeds, flowers, and leaves, but not the pulp. The main focus of our experiment was to optimize the extraction so as to increase the antioxidative activity of the pumpkin pulp. Variable extraction conditions were used for this purpose, i.e., the type and concentration of the solvent, as well as the time and temperature of the process. In addition, the experiment involved a comparative analysis of the antioxidative potential of 14 pumpkin cultivars of the Cucurbita maxima species. The study showed considerable diversification of the antioxidative activity of different pumpkin cultivars.

Infection on plant caused by Aspergillus niger leads to the destruction of quantity and quality of crop yields. Normally, this disease is solved by the chemical fungicides. Therefore, this study was carried out to seek a potential natural fungicide from fruit waste which is safer and economical to inhibit Aspergillus niger. Cucurbita maxima (pumpkin) seeds and Punica granatum (pomegaranate) peels were extracted using maceration method with 80 % ethanol. Brine Shrimp Lethality Assay (BLSA) was used to test the presence of bioactive components in the extracts at concentration of 10 µg/mL, 100 µg/mL and 1000 µg/mL and they are expressed in terms of LC50 (Median Lethal Concentration) respectively. The study revealed that Cucurbita maxima extract was inactive, while Punica granatum extract and the mixture of both extracts at ratio 1:1 were active at 1000 µg/mL. Furthermore, the antifungal activity of Cucurbita maxima extract, Punica granatum extract, and mixture of both extracts were further tested using well-diffusion method against A. niger at 25 mg/mL, 50 mg/mL, 75 mg/mL and 100 mg/mL respectively. The findings revealed the mixture of both extracts were exerted effectively against A. niger at the lowest concentration with 20.67±2.52 mm and this gave significant zone of inhibition. The result of the study indicates that the mixture extraction of pomegranate peels and pumpkin seeds at 25 mg/mL has a great potential to be formulated as commercial bio-fungicide.

Pumpkin (Cucurbita maxima) seeds are important food materials used by most Nigerian families due to their delicious taste, aroma and appeal. In this study, changes between chemical composition of processed and unprocessed pumpkin seeds (Cucurbita maxima) was investigated. The nutritional compositions were analyzed by standard methods. The vitamin A contents 36.83 μg/100g and 33.72 μg/100g respectively. The copper, zinc, magnesium,phosphorus and iron contents of processed seeds were; 0.063, 0.43, 47.67, 58.19 and 610.77 ppm respectively while the values for unprocessed were; 0.047, 0.41, 36.73, 58.45 and 211.19 ppm respectively with significant difference between the processed and unprocessed. The finding suggests that pumpkin seed is rich in this vitamin and minerals. If utilized efficiently. It can also ameliorate micronutrients deficiency problem in population of all age groups.

Pumpkin (Cucurbita maxima) seeds are a rich source of ingredients such as aminoacids, fatty acids, minerals, and phytochemicals exhibiting nutraceutical effects on human health. In this work, partially defatted pumpkin seeds flour, a by-product obtained during the manufacture of pumpkin seeds oil, was studied as an additive for common wheat flour. We explored the physico-chemical properties as well the content in amino acids of the partially defatted pumpkin seeds. The obtained results revealed that partially defatted pumpkin seeds are a good source of protein (42.75% d.m.), lipids (12.28% d.m.), total carbohydrates (37.4% d.m.), from which crude fiber (26.64% d.m.). This by-product presents a high mineral content (mg/100g): potassium (1290), magnesium (693), iron (87.8), zinc (11.5) and copper (2.49).The partially defatted pumpkin seeds proteins contain significant amounts of essential amino acids such as valine, histidine, isoleucine, leucine, threonine and methionine.

Abstract. Background: Here, we update an earlier systematic review on the preventive efficacy of active compression stockings in patients with diagnosed proximal deep venous thrombosis (DVT) by including the results of recently published trials. The aims are to synthesize the results of the original studies, and to identify details to explain heterogeneous results. Methods: We searched the Cochrane Library, PubMed, Scopus, and Medline for original studies that compared the preventive efficacy of active compression stockings with placebo or no compression stockings in patients with diagnosed proximal DVT. Only randomized controlled trials (RCTs) were included. Results: Five eligible RCTs with a total of 1393 patients (sample sizes ranged from 47 to 803 patients) were included. In three RCTs, patients started to wear compression stockings, placebo stockings or no stockings within the first three weeks after the diagnosis of DVT. The results of two RCTs indicate a statistically significant reduction in post-thrombotic syndrome (PTS) of 50% or more after two or more years. The result of one RCT shows no preventive effect of compression stockings at all. Due to the heterogeneity of the study results, we refrained from pooling the results of the RCTs. In a further RCT, randomization to groups with and without compression stockings took place six months after the diagnosis of DVT, and in another RCT, only patients with the absence of PTS one year after the diagnosis of DVT were analyzed. One RCT revealed a significant reduction in symptoms, whereas another RCT failed to show any benefit of using compression stockings. Conclusions: At this time, it does not seem to be justifiable to entirely abandon the recommendations regarding compression stockings to prevent PTS in patients with DVT. There is evidence favoring compression stockings, but there is also evidence showing no benefit of compression stockings.
