The standard cryopreservation process previously developed for oil palm clones using shiny white, finger-like somatic embryos could be applied in some cases to standard cultures. Its efficiency was markedly improved by completing the 7-day pregrowth period on 0.75 M sucrose by an additional dehydration period carried out either by placing the embryos in the air current of the laminar flow cabinet or in an air tight box containing silica gel. This improved process was successfully applied to 7 different clones. It will facilitate the routine uof cryopreservation for oil palm cultures.

: Alcohol-induced osteoporosis is a significant health concern, impairing bone formation and enhancing resorption, thereby weakening skeletal integrity. This study examines the effects of palm vitamin E on bone histomorphometry in a male rat model of alcohol-induced osteoporosis. : Three-month-old Sprague-Dawley rats were randomized into seven groups, with one baseline control group (BC) and six experimental groups undergoing a two-phase treatment.

This review provides an overview of the main vegetable oils of different botanical origin and composition that can be used for frying worldwide (olive and extra-virgin olive oil, high-oleic sunflower oil, rapeseed oil, peanut oil, rice bran oil, sunflower oil, corn oil, soybean oil, cottonseed oil, palm oil, palm kernel oil and coconut oil) and their degradation during this process. It is well known that during this culinary technique, oil's major and minor components degrade throughout different reactions, mainly thermoxidation, polymerization and, to a lesser extent, hydrolysis. If severe high temperatures are employed, isomerization to fatty acyl chains and cyclization are also possible.

Oil palm () yield is impacted by abiotic stresses, leading to significant economic losses. To understand the core abiotic stress transcriptome (CAST) of oil palm, we performed RNA-Seq analyses of oil palm leaves subjected to drought, salinity, waterlogging, heat, and cold stresses. A total of 19,834 differentially expressed genes (DEGs) were identified.

African eggplant (Solanum aethiopicum gilo group) is a nutritious vegetable widely commercialized in Ghana. In the 2021 planting season (May-July), collar rot symptoms were observed on African eggplant on a farm at Domeabra, Legon, and Okumaning in the Central (N5° 48' 11″, W1° 26' 48″), Greater Accra (N5° 39' 34″, W0° 11' 34″) and Eastern (N6° 8' 34″, W0° 55' 59″) regions of Ghana, respectively. Disease incidence was 8-15% in the different farms.
