In modern agriculture, control of insect pests is achieved by using insecticides that can also have lethal and sublethal effects on beneficial non-target organisms. Here, we investigate acute toxicity and sublethal effects of four insecticides on the males' sex pheromone response and the female host finding ability of the Drosophila parasitoid Leptopilina heterotoma. The nicotinic acetylcholine receptor antagonists acetamiprid, flupyradifurone and sulfoxaflor, as well as the acetylcholinesterase inhibitor dimethoate were applied topically as acetone solutions.

Background: Erectile dysfunction (ED) is a prevalent male sexual disorder, commonly associated with hypertension, though the underlying mechanisms remain poorly understood.
Objective: This study aims to explore the role of Fatty acid synthase (Fasn) in hypertension-induced ED and evaluate the therapeutic potential of the Fasn inhibitor C75.
Materials And Methods: Erectile function was assessed by determining the intracavernous pressure/mean arterial pressure (ICP/MAP) ratio, followed by the collection of cavernous tissue for transcriptomic and non-targeted metabolomic analyses.

Ligustilide, a phthalide compound extracted from Umbelliferae plants such as Angelica sinensis and Ligusticum chuanxiong, has been proven to possess various pharmacological activities, such as anti-inflammatory, anti-tumor, anti-atherosclerosis, anti-ischemic stroke injury, and anti-Alzheimer's disease properties. In recent years, it has shown great potential, particularly in the treatment of locomotor system diseases. Studies have shown that ligustilide has significant therapeutic effects on various locomotor system diseases, including osteoporosis, osteoarthritis, femoral head necrosis, osteosarcoma, and muscle aging and injury.

The industrial advancement of downstream products resulting from the directed hydrogenation of maleic anhydride is hindered by the limitations related to the activity and stability of catalysts. The development of nonprecious metal intermetallic compounds, in which active sites are adjustable in the local structures and electronic properties embedded within a distinct framework, holds immense potential in enhancing catalytic efficacy and stability. Herein, we report that nickel-based silicides catalysts, RNiSi (R = Ca, La, and Y), afford high efficiency in the selective hydrogenation of maleic anhydride.

Emerging evidence indicates that intratumor bacteria exist as an active and specific tumor component in many tumor types beyond digestive and respiratory tumors. However, the biological impact and responsible molecules of such local bacteria-tumor direct interaction on cancer therapeutic response remain poorly understood. Trastuzumab is among the most commonly used drugs targeting the receptor tyrosine-protein kinase erbB-2 (ErbB2) in breast cancer, but its resistance is inevitable, severely limiting its clinical effectiveness.
