Insights on the Nutritional Profiling of Cantaloupe (Cucumis melo L.) via 1-Naphthalene Acetic Acid.

The nutritional components of cantaloupe, including vitamins, minerals, antioxidants, and dietary fiber, contribute to overall health, improved immunity, hydration, and protection against chronic diseases. This study was conducted to investigate the influence of different concentrations (0 (control), 100, 150, and 200 ppm) of 1-naphthalene acetic acid (1-NAA) on the nutritional components of the cantaloupe (Cucumis melo L. Var. Super White Honey). All the studied treatments were applied twice at the 2nd and 4th leaf stages. The applied concentrations of 1-NAA significantly improved the sex expression and fruit yield attributes. Different nutritional components like proximate contents, minerals, vitamins, selected fatty acids, and amino acids were analyzed. The results showed that the maximum moisture content, proteins, carbohydrates, ash, and energy were recorded with 100 ppm. The higher lipids were recorded during the supplementation of 150 ppm. Significantly greater fibers were recorded using 200 ppm. Regarding minerals, 100 ppm was found to be the best as it increased calcium (Ca), magnesium (Mg), potassium (K), sodium (Na), phosphorous (P), manganese (Mn), copper (Cu), iron (Fe), and zinc (Zn). Vitamins were also found to be the maximum with 100 ppm, including vitamin A, vitamin B, vitamin C, vitamin D, vitamin E, and vitamin K. Total selected fatty acids and amino acids were also found significantly greater in the fruits administered 100 ppm.

In vitro anti-Toxoplasma gondii activity of Ganoderma lucidum extracts.

OBJECTIVE: Ganoderma extracts have the potential to be used as anti-cancer, anti-inflammatory, immunomodulator, and antimicrobial agents, as evaluated in numerous studies. This study was aimed to determine the lethal and inhibitory effects of aqueous, hydroalcoholic, and alcoholic extracts of Ganoderma lucidum on Toxoplasma gondii RH strain tachyzoites, in vitro. RESULTS: All three types of extracts showed toxoplasmacidal effects. The highest percentage of mortality was related to hydroalcoholic extract. The EC50 of Ganoderma extracts for tachyzoites were 76.32, 3.274, and 40.18 for aqueous, hydroalcoholic and alcoholic extracts, respectively. The selectivity index obtained for hydroalcoholic extract was 71.22, showing the highest activity compared to other extracts. According to our findings, the hydroalcoholic part was the most effective substance among the extracts. This basic study showed obvious anti-toxoplasma effect of Ganoderma lucidum extracts. These extracts can be used as candidates for further in-depth and comprehensive studies especially In vivo experiments to prevent toxoplasmosis.

Rescue effect of curcumin against copper toxicity.

Turmeric has long been used not only as an indispensable part of Asian cuisine but as a medicinal herb for dressing wounds, bites, burns, treating eye infections and acne. Curcuminoids are the active substances and their synthetic derivatives (i.e. diacetylcurcumin (DAC) and metal-curcumin complexes) possess an incredibly wide range of medicinal properties that encompass chelation capacity for multiple heavy metals, antioxidant activity, anti-inflammatory properties, cytotoxicity against cancerous cells, antiviral and antibacterial effects, antihypertensive and insulin sensitizing role, and regulatory role on apoptosis. The aforementioned properties have put curcumin on spotlight as a potential treatment for ailments such as, hepatic diseases, neurodegenerative diseases, metabolic syndrome, dyslipidemia, cardiovascular disease, auto-immune diseases, malignancies and conditions associated with metal overload. Copper is essential for major biological functions, however, an excess causes chronic ailments including neurodegenerative disorders. The fascinating approach of curcumin could alleviate such effect by forming a complex. Thus, this review aims to present available data on the effect of copper-curcumin interaction in various in vitro, ex-vivo in vivo, and clinical studies.

Electrocoagulation of palm oil mill effluent as wastewater treatment and hydrogen production using electrode aluminum.

Palm oil mill effluent (POME) is highly polluting wastewater generated from the palm oil milling process. Palm oil mill effluent was used as an electrolyte without any additive or pretreatment to perform electrocoagulation (EC) using electricity (direct current) ranging from 2 to 4 volts in the presence of aluminum electrodes with a reactor volume of 20 L. The production of hydrogen gas, removal of chemical oxygen demand (COD), and turbidity as a result of electrocoagulation of POME were determined. The results show that EC can reduce the COD and turbidity of POME by 57 and 62%, respectively, in addition to the 42% hydrogen production. Hydrogen production was also helpful to remove the lighter suspended solids toward the surface. The production of Al(OH)XHO at the aluminum electrode (anode) was responsible for the flocculation-coagulation process of suspended solids followed by sedimentation under gravity. The production of hydrogen gas from POME during EC was also compared with hydrogen gas production by electrolysis of tap water at pH 4 and tap water without pH adjustment under the same conditions. The main advantage of this study is to produce hydrogen gas while treating POME with EC to reduce COD and turbidity effectively.

Enhancement of lipase catalyzed-fatty acid methyl esters production from waste activated bleaching earth by nullification of lipase inhibitors.

This study sought to identify inhibitory factors of lipase catalyzed-fatty acid methyl esters (FAME) production from waste activated bleaching earth (wABE). During the vegetable oil refinery process, activated bleaching earth (ABE) is used for removing the impure compounds, but adsorbs vegetable oil up to 35-40% as on a weight basis, and then the wABE is discarded as waste material. The impurities were extracted from the wABE with methanol and evaluated by infra-red (IR) spectroscopy, which revealed that some were chlorophyll-plant pigments. The chlorophylls inhibited the lipase during FAME conversion from wABE. The inhibition by a mixture of chlorophyll a and b was found to be competitive. The inhibition of the enzymatic hydrolysis of waste vegetable oil contained in wABE by chlorophyll a alone was competitive, while the inhibition by chlorophyll b alone was non-competitive. Furthermore, the addition of a small amount of alkali nullified this inhibitory effect and accelerated the FAME production rate. When 0.9% KOH (w/w wABE) was added to the transesterification reaction with only 0.05% lipase (w/w wABE), the maximum FAME production rate improved 120-fold, as compared to that without the addition of KOH. The alkali-combined lipase significantly enhanced the FAME production rate from wABE, in spite of the presence of the plant pigments, and even when a lower amount of lipase was used as a catalyst.

Effects of a food supplementation program on the nutritional status of pregnant women in Bangladesh.

BACKGROUND: The Government of Bangladesh implemented a comprehensive nutrition intervention in 1997 to reduce the rates of malnutrition among women and children. The pilot program, the Bangladesh Integrated Nutrition Program (BINP), adopted a multisectoral approach targeting women and children through food supplementation, home gardening, and health and nutrition education. OBJECTIVE: This paper estimates the effectiveness of BINP's food supplementation and nutrition education on the nutritional status of pregnant women. Methods. Three effectiveness measures were considered: target efficiency, improvements in the nutritional status of beneficiaries, and the persistence of nutritional effects. To isolate the effects of the intervention, the nutritional status of participants and nonparticipants was compared after controlling for various demographic and socioeconomic characteristics. Data were collected in 2000 from a random sample of 3262 households in a BINP intervention area. RESULTS: Thirty-nine percent of pregnant women were correctly targeted by the program's food supplementation activities. The nutrition program reduced the prevalence of thinness among participant pregnant women by about 3 percentage points per month of enrollment. The prevalence of thinness among program graduates was 62%, which was much higher than that of the matched (nonparticipant) group (35%). This finding is perplexing but it may simply imply that those who enrolled at the initial phase of the project were severely underweight and they fell back to their original status within a short period of time. CONCLUSIONS: The nutrition program was intended to improve the nutritional status of women in the longer run through the provision of nutrition education during the food supplementation phase. The prevalence of thinness or severe underweight in women who exited the program after completion of the enrollment period was found to be much higher than in women of similar age and socioeconomic status in the community. This apparent lack of persistence of program benefits requires careful re-evaluation of alternative mechanisms for improving the long-term nutritional status of women.
