Carboxylic acids and their derivatives are ubiquitous compounds in organic chemistry, and are widely commercially available in a large structural variety. Recently, carboxylic acids have been frequently used as non-toxic and environmentally benign alternatives to traditional organohalide coupling partners in various carbon-carbon and carbon-heteroatom cross-coupling reactions. Along this line, several methods have been reported for the synthesis of nitrogen-containing organic compounds through decarboxylative cross-coupling reactions between carboxylic acids and N-H compounds. This review focuses on recent advances and discoveries on these reactions with special attention on the mechanistic aspects of the reactions.

The present study was conducted to evaluate the effect of humic substances on performance and selected blood biochemical parameters in turkeys. A total of twenty 6-week-old turkey hybrids (Big 6) were divided into two groups. The first group of turkeys was fed the basal diet without any supplementation of humic substances as a control group.

Over the last decades, human infertility has become a major concern in public health, with severe societal and health consequences. Growing evidence shows that endocrine disruptors chemicals (EDCs) have been considered as risk factors of infertility. Their presence in our everyday life has become ubiquitous because of their universal use in food and beverage containers, personal care products, cosmetics, phytosanitary products.

Background: The prognostic significance of the chemokine receptor CCR7 in diffuse large B-cell lymphoma (DLBCL) has been reported previously. However, the detailed mechanisms of CCR7 in DLBCL, particularly regarding its interaction with lenalidomide treatment, are not fully understood.
Methods: Our study utilized bioinformatics approaches to identify hub genes in SU-DHL-2 cell lines treated with lenalidomide compared to control groups.

Background: Intestinal parasitic infections (IPIs) are a major health problem among the Karen hill tribe in Thailand. This study aimed to evaluate the effect of an integrated intervention program of drug therapy combined with water, sanitation, and hygiene (WASH) education on reinfection with IPIs among the Karen hill tribe in an endemic area of northern Thailand.
Methods: A quasi-experimental study was conducted in two Karen villages, involving 691 residents, in Omkoi District, Chiang Mai Province; one village was designated as the intervention group and the other as the control group.

Objectives: To evaluate the self-etch bonding potential of universal adhesive systems with varying acidic compositions by analyzing the wettability properties, topographical change, and microshear bond strength (µSBS) to enamel.
Methods: Eight universal adhesives were tested: All-Bond Universal (Bisco), Ambar Universal (FGM), Gluma Bond Universal (Kulzer), OptiBond Universal (Kerr), Peak Universal Bond (Ultradent), Prime&Bond Universal (Dentsply), Singlebond Universal (3 M ESPE), and Tetric N-Bond Universal (Ivoclar). Bovine incisors were prepared and treated with each adhesive according to the manufacturer's instructions.
