Research ArticleOpen accessIn the keywordsInhibitory Effects of Artemisia afra Extracts on the Bio-Activity of Banana TyrosinaseTsholofelo Motshologane, Jacobus Pieter Hough Van WykMelasma, formerly known as chloasma, is an acquired pigmentary condition, occurring most commonly on the face of humans. This disorder, which is more prevalent in females and darker skin types, is predominantly attributed to Ultraviolet (UV) exposure and hormonal influences. This condition is caused by an over-production of melanin, a pigment that gives color to the skin, hair, and eyes … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 18 Jan 2025 · 4,618 accessesView PDFCite

Zepernick and Timler (Rutaceae) Stem and Root BarkLassané Ouédraogo, Aminata Pagnimdebsom Nacoulma et al.Zanthoxylum zanthoxyloides, a medicinal plant overexploited in Burkina Faso due to the use of its roots for therapeutic purposes has been studied and it seems that the profile of the powder from stem and root bark are almost similar. This study aims to compare the botanical, physicochemical, and phytochemical parameters of Z. zanthoxyloides powder from stem and root bark for … …American Journal of Applied Sciences, Vol. 21, Issue 1 · 9 Sep 2024 · 8,733 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntifungal Activity of Jatropha Curcas Linn on Candida Albicans and Candida Tropicalis Associated with Neonatal and Infantile Infections in Yola, NigeriaJames Hamuel Doughari, Martha AbrahamOne hundred and eighty (180) stool samples collected of neonates and infants from three selected health facilities in Yola, Adamawa State Nigeria. The samples were subjected to both microscopic, biochemical test and cultural identification. Bromocresol green agar and Germ tube test was used to identify Candida species. Culture of the stool samples on SDA yielded 32 yeast cells with Candida … …American Journal of Agricultural and Biological Sciences, Vol. 16, Issue 1 · 7 Sep 2021 · 7,533 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoil Organic Carbon Pool and its Storage in Arial Beel Wetland Soils of BangladeshMd. Faruque Hossain, ASM Maksud Kamal, Monera Akhter Eva et al.The actual quantity of Soil Organic Carbon (SOC) stored in wetlands can only be estimated within a broad range of uncertainty. An accurate assessment of the size and distribution of the SOC storages in wetland resources is very difficult to obtain, therefore, the proposed research objective is to measure SOC storage and its pool on wetland soils of Arial beel … …American Journal of Environmental Sciences, Vol. 16, Issue 3 · 17 Aug 2020 · 7,382 accessesView PDFCite
Research ArticleOpen accessIn the abstractFractionation of Organic Carbon in Arial Beel Wetland Soils of BangladeshMonera Akter Eva, Mahmudul Islam Piash, Md. Faruque Hossain, Zakia ParveenA study was conducted to determine the organic carbon fractions in the vertical sections of a benchmark wetland soil of Bangladesh (Arial Beel) and their dynamics that directly affect the biogeochemistry of soil, water and plant biomass ecosystem. Two distinctive soil series viz. Sara and Arial are characterized such as pH, moisture content, textural class, CEC, organic carbon (SOC), bulk … …American Journal of Environmental Sciences, Vol. 14, Issue 2 · 4 May 2018 · 9,134 accessesView PDFCite
