Optimization and Standardization of the Extraction Method of Del. Seeds (Zygophyllaceae) Used in the Formulation of an Antiparasitic Phytomedicine.

Del. (Zygophyllaceae) is widely used in traditional medicine, both human and veterinary, throughout Africa for its many properties, including antiparasitic properties. This experimental study aims to optimize the extraction conditions of the seeds of Del.

[Occupational asthma in a laboratory technician].

This observation reports the case of an occupational allergic asthma in a laboratory technician, caused by exposure to formaldehyde. She experienced feelings of discomfort during low exposure, below the regulatory exposure thresholds. Sent to occupational medicine, signs of an asthma attack were noted by the doctor.

HPV vaccine hesitancy among parents and caregivers of adolescents in Northern Nigeria.

Background: The recent introduction of the HPV vaccine into Nigeria's routine immunization schedule has brought parental vaccine hesitancy to the forefront. This cross-sectional study, conducted in Kano State, a region with historically low immunization rates, is crucial in assessing the level of parental hesitancy and uncovering its determinants, potentially informing future public health policies.

Methods: The participants were a representative sample of parents or caregivers of children aged 9-14 years ( = 1071) in Kano State and were selected via a multi-stage sampling method.

In-Depth Study of Ambipolar Charge-Transport Regime through External Triggers and Gas Sensing.

Ambipolar devices are a hot topic in research tables due to their unique advantage in reducing the size of the electrical system and enhancing its efficiency. Here, we report a bilayer heterojunction device constructed using octafluoro-vanadyl-phthalocyanine (VOFPc) and lutetium bisphthalocyanine (LuPc), which exhibits both p- and n-type behaviors under oxidizing (NO and O) and reducing gas (NH) species depending on the humidity level and temperature variations. The initial polarity of the device is identified as n-type by measuring a current decrease under oxygen exposure.
