The potential of industrial sludge and textile solid wastes for biomass briquettes with avocado peels as a binder
Environ Sci Pollut Res Int. 2023 Jul 4. doi: 10.1007/s11356-023-28493-x. Online ahead of print.ABSTRACTProducing biomass briquettes from industrial solid wastes is a more environmentally friendly way to provide alternative energy and is essential for Ethiopia to satisfy its growing energy needs while also ensuring efficient waste management in the expansion of industrial parks. The main objective of this study is to produce biomass briquettes from a mixture of textile sludge and cotton residue using avocado peels as a binder. Textile solid waste, avocado peels, and sludge were dried, carbonized, and turned into powder to m...

The impact of dual- versus single-dosing and fatty food co-administration on albendazole efficacy against hookworm among children in Mayuge district, Uganda: Results from a 2x2 factorial randomised controlled trial
Conclusions/SignificanceIn Ugandan school children, dual-dose albendazole improves the cure rate of hookworm compared to single-dose albendazole. However, there was no significant improvement in cure rate or egg reduction rate of hookworm with fatty-food co-administration. Dual-dose albendazole is a feasible alternative for improving drug effectiveness against hookworm infection and minimising drug resistance. Trial registrationPACTR202202738940158.

Microwave-assisted autohydrolysis of avocado seed for the recovery of antioxidant phenolics and glucose
This study describes the valorization of avocado seed (AS) within a green biorefinery concept using microwave-assisted autohydrolysis. After the treatment at temperatures of 150-230 °C for 5 min, the resulting solid and liquor were characterized. The temperature of 220 °C led to the simultaneous optimal values of antioxidant phenolics/flavonoids (42.15 mg GAE/g AS, 31, 89 RE/g AS, respectively) and glucose + glucooligosaccharides (38.82 g/L) in the liquor. Extraction with ethyl acetate allowed the recovery of the bioactive compounds while maintaining the polysaccharides in the liquor. The extract was rich in vanillin (99...

Molecules, Vol. 28, Pages 4393: Endogenous n-Alkanes in Vegetable Oils: Validation of a Rapid Offline SPE-GC-FID, Comparison with Online LC-GC-FID and Potential for Olive Oil Quality Control
p
Moret
The potential of endogenous n-alkane profiling for the assessment of extra virgin olive oils (EVOO) adulteration (blends with cheaper vegetable oils) has been studied by relatively few authors. Analytical methods used for this purpose often involve tedious and solvent-intensive sample preparation prior to analytical determination, making them unattractive. A rapid and solvent-sparing offline solid phase extraction (SPE) gas chromatography (GC) flame ionization detection (FID) method for the determination of endogenous n-alkanes in vegetable oils was, therefore, optimized and validated. The optimized method d...

Health risk assessment of potentially toxic elements (PTEs) concentrations in soil and fruits of selected perennial economic trees growing naturally in the vicinity of the abandoned mining ponds in Kuba, Bokkos Local Government Area (LGA) Plateau State, Nigeria
In conclusion, the results and risk assessment provided by this study indicate that human exposure to fruits from abandoned mines suggests a high vulnerability of the local community to PTE toxicity. Long-term preventive measures to safeguard the health of the residents need to be put in place. (Source: Environmental Geochemistry and Health)

Natural Anticancer Agents: Their Therapeutic Potential, Challenges,s and Promising Outcomes
Curr Med Chem. 2023 May 2. doi: 10.2174/0929867330666230502113150. Online ahead of print.ABSTRACTCancer, the second leading cause of death worldwide, is a major health problem. Chemotherapy, radiation therapy and surgery are current treatments for cancer. Most anticancer drugs have severe toxic effects and are required to be administered in cycles to reduce toxicity and prevent resistance. Plant-based drugs have shown a potential for treatment of cancer, and various plant secondary metabolites have shown promising antitumor activity against several cancer cell lines, such as leukemia, colon cancer, prostate cancer, breast ...

Biocontrol and plant growth promoting traits of two avocado rhizobacteria are orchestrated by the emission of diffusible and volatile compounds
Avocado (Persea americana Mill.) is a tree crop of great social and economic importance. However, the crop productivity is hindered by fast-spreading diseases, which calls for the search of new biocontrol alternatives to mitigate the impact of avocado phytopathogens. Our objectives were to evaluate the antimicrobial activity of diffusible and volatile organic compounds (VOCs) produced by two avocado rhizobacteria (Bacillus A8a and HA) against phytopathogens Fusarium solani, Fusarium kuroshium, and Phytophthora cinnamomi, and assess their plant growth promoting effect in Arabidopsis thaliana. We found that, in vitro, VOCs e...

The impact of avocado intake on anthropometric measures among Hispanic/Latino children and adolescents: a cluster randomized controlled trial
/Objective: While the association between avocado consumption and low metabolic risk has been shown in some studies conducted in adults, little is known about the potential effects of avocado consumption on health outcomes in children and adolescents. Thus, we investigated the impact of two levels of avocado allotment, plus a standard nutrition education, on measures of adiposity in children and adolescents ( (Source: Clinical Nutrition ESPEN)

Evaluating how avocado residue addition affects the properties of cassava starch-based foam trays
Int J Biol Macromol. 2023 Apr 5:124348. doi: 10.1016/j.ijbiomac.2023.124348. Online ahead of print.ABSTRACTAvocado seed (AS) is an interesting residue for biopackaging because it has high starch content (41 %). We have prepared composite foam trays based on cassava starch containing different AS concentrations (0, 5, 10 and 15 % w/w) by thermopressing. Composite foam trays with AS were colorful because this residue contains phenolic compounds. The composite foam trays 10AS and 15AS were thicker (2.1-2.3 mm) and denser (0.8-0.9 g/cm3), but less porous (25.6-35.2 %) than cassava starch foam (Control). High AS concentrations ...

Avocado seed waste bioconversion into poly(3-hydroxybutyrate) by using Cobetia amphilecti and ethyl levulinate as a green extractant
Int J Biol Macromol. 2023 Apr 5:124371. doi: 10.1016/j.ijbiomac.2023.124371. Online ahead of print.ABSTRACTThe avocado processing industry produces up to 1.3M tons of agro-waste annually. Chemical analysis of avocado seed waste (ASW) revealed that it is rich in carbohydrates (464.7 ± 21.4 g kg-1) and proteins (37.2 ± 1.5 g kg-1). Optimized microbial cultivation of Cobetia amphilecti using an acid hydrolysate of ASW, generated poly(3-hydroxybutyrate) (PHB) in a 2.1 ± 0.1 g L-1 concentration. The PHB productivity of C. amphilecti cultivated on ASW extract was 17.5 mg L-1 h-1. The process in which a novel ASW substrate was...
