Labisia pumila (Myrsinaceae), is a popular herb among the women in Malaysia known locally as "Kacip Fatimah". Recently many nutraceutical products containing the powdered or extracted parts of the plant have become available for women's health care. However no evaluation of the effect of the repeated dosing of any herbal product of this plant had been undertaken prior to a 28-day sub-acute study presented in this report. The results showed that a dose of 50mg/kg of an aqueous extract of L. pumila corresponded to no-adverse-effect-level (NOAEL), whereas higher doses were associated with some toxicity concerns.

Schistosomiasis, caused by Schistosoma worms, is a major neglected tropical disease in Africa, this disease is ranked as second after malaria. Nanotechnology is important for treating schistosomiasis while minimizing chemotherapy side effects. The current investigate aimed to assess the effectiveness of biosynthesized zinc oxide nanoparticles (ZnO NPs), which were used for the first time in an attempt to find alternative treatment for schistosomiasis and synthesized by Origanum majorana, and to compare them with praziquantel (PZQ), the only chemical treatment approved by the World Health Organization.

Eurema mandarina is a pierid butterfly that primarily feeds on plants in the family Fabaceae. In mainland Japan, adult females preferentially lay eggs on Albizia julibrissin and Lespedeza cuneata. In the field, females may oviposit on non-fabaceous plants, although rarely.

In this study, copper nanoparticles with an average particle size of 2-4 nm were synthesized using the green extract of Thunb. The catalytic activity and dye degradation efficiency of Cu NPs were evaluated using ultraviolet spectroscopy. To confirm that Cu NPs can continuously remove organic dyes, this study used Cu/Lj-C composite material adsorbed on cotton balls as a simulated bed to study the cyclic catalytic activity of Cu NPs for the reduction of methylene blue by sodium borohydride (NaBH).

Zirconium dioxide nanoparticles (ZrO NPs) have gained significant attention due to their excellent bioavailability, low toxicity, and diverse applications in the medical and industrial fields. In this study, ZrO NPs were synthesized using zirconyl oxychloride and the aqueous leaf extract of as a stabilizing agent. Analytical techniques, including various spectroscopy methods and electron microscopy, confirmed the formation of aggregated spherical ZrO NPs, ranging from 15 to 30 nm in size, with mixed-phase structure composed of tetragonal and monoclinic structures.
