In this study, we investigated in vitro the potential of to produce bioactive secondary metabolites that can be used as alternatives to synthetic compounds. The study focused on analyzing two extracts of using ethyl acetate and -butanol solvents with different polarities. The extracts were examined using phytochemical analysis to determine the content of polyphenols, flavonoids, tannins, and alkaloids. Thin-layer chromatography (TLC) and Gas chromatography-mass spectroscopy (GC-MS) analysis were used to profile volatile organic metabolites (VOCs) present in the extracts. Furthermore, the extracts were tested for their antifungal ability using the poison food technique. For measuring antioxidant activity, the 1,1-diphenyl-2-picryl-hydrazyl (DPPH) test was used. was shown to have a significantly high content of tannins and alkaloids, with a noticeable difference between the two extracts. GC-MS analysis identified 33 potential compounds with numerous benefits that could be used in agriculture and the medicinal industry. Moreover, strong antifungal activity was identified against by 94.44%, sp. by 77.04%, and by 51.48; similarly, the IC of antioxidant activity was estimated for ethyl acetate extract by 71.47% and -butanol extract by 56.01%. This leads to the conclusion that VOCs play a significant role as an antifungal and antioxidant agent when taking into account the advantageous bioactive chemicals noted in the extracts. However, to our knowledge, this is the first study in Algeria presenting detailed phytochemical analysis and GC-MS profiling of for two extracts, ethyl acetate and -butanol.

Introduction: Exposure to environmental factors ( air pollution and second-hand tobacco smoke) have been associated with impaired lung function. However, the impact of environmental factors on lung health is usually evaluated separately and not with an exposomic framework. In this regard, breath analysis could be a noninvasive tool for biomonitoring of global human environmental exposure.

Cassava is a starchy staple typically consumed in tropical countries; however, its high moisture content renders it susceptible to post-harvest deterioration. Fermentation has been used to improve shelf-life, functional properties, nutrient bioavailability, minimize toxic compounds, and alter aroma. In this study, the effect of added salt (5-25 %) on the pH, titratable acidity (TTA), and volatile compounds (VOCs) in cassava fermented was investigated.

Background: Inflammation is the body's innate reaction to foreign pathogens and serves as a self-regulating mechanism. However, the immune system can mistakenly target the body's own tissues, triggering unnecessary inflammation. For millennia, medicinal plants have been employed for the treatment of diseases.

Background: Iduronate-2-sulfatase (IDS) deficiency (MPS II; Hunter syndrome) is a disorder that exhibits peripheral and CNS pathology. The blood brain barrier (BBB) prevents systemic enzyme replacement therapy (ERT) from alleviating CNS pathology. We aimed to enable brain delivery of systemic ERT by using molecular BBB-Trojans targeting endothelial transcytosis receptors.

Speechreading-gathering speech information from talkers' faces-supports speech perception when speech acoustics are degraded. Benefitting from speechreading, however, requires listeners to visually fixate talkers during face-to-face interactions. The purpose of this study is to test the hypothesis that preschool-aged children allocate their eye gaze to a talker when speech acoustics are degraded.
