The outer part of a tree, known as the bark, protects internal tissues from external conditions and attacks microorganisms. Its antifungal activities are due to presence chemicals in this bark. This study aimed at evaluating toxicity triterpenoids steroids bark Pinus merkusii against Phanerochaete chrysosporium (white-rot). were isolated n-hexane extract through column chromatography. Then, act...

Abstract Bio-based and biodegradable plastics such as mulching films are widely used in agricultural field sites. However, there limited studies of their impact on plant development health even though an important soil-borne pathogen F . solani has been reported to associate with various types bio-based plastics, especially polybutylene succinate-co-adipate (PBSA). To evaluate the influence PBS...

In vitro fertilisation (IVF) is the process by which oocytes and sperm are mixed in a petri dish, allowing fertilisation to occur outside the mother's body. Similarly to the genetic advantage obtained using artificial insemination with respect to the paternal parent, IVF affords the ability to more stringently select the maternal parent. Oocytes from one valuable female can be transferred into ...

Background. Streptococcus mutans is the leading cause of dental caries. One many medicinal plants, purple leaf [Graptophyllum pictum (L.) Griff], which contains flavonoids, alkaloids, tannins, steroids, and saponins, a potential antibacterial agent.
 Objective. This study aimed to determine activity extract (Graptophyllum L. Griff) against mutans.
 Methods. were suspended in several G...

Essential oils are a rich source of compounds for botanical pesticides. This study aimed to characterize the chemical composition essential oil from parsley seeds and its phytotoxicity against germination initial growth wheat mustard. The main were α-pinene, β-pinene, apiol. In Petri dish experiment, inhibited both species. However, seedlings species was more inhibited, especially wheat. conclu...

Drosophila melanogaster larvae are model systems for studies of development, synaptic transmission, sensory physiology, locomotion, drug discovery, and learning and memory. A detailed behavioral understanding of larvae can advance all these fields of neuroscience. Automated tracking can expand fine-grained behavioral analysis, yet its full potential remains to be implemented for the larvae. All...
