A total of 38 new benzohydrazide derivatives bearing the 4-aminoquinazoline moiety were designed and synthesized based on the active subunit combination approach and tested in detail for their inhibition activities against eight agricultural phytopathogenic fungi. The bioassay results indicated that many of the synthesized compounds exhibited extraordinary fungicidal activities in vitro against the tested fungi. For example, compounds , , , and had EC (half-maximal effective concentration) values of 0.

Periodontal diseases afflict 20-50% of the global population and carry serious health and economic burdens. Chronic periodontitis is characterized by inflammation of the periodontal pocket caused by dysbiosis. This dysbiosis is coupled with an increase in the population of Treponema denticola, a spirochete bacterium with high mobility and invasivity mediated by a number of virulence factors.

Seaweeds have been utilized as food, fodder, fertilizer, and medicine since ancient times; nevertheless, they have received only a little attention. In the current work, we extracted the sulfated polysaccharide from a marine source and investigated its anti-arthritic potential . The isolated and freeze-dried polysaccharide was tested for acute oral toxicity based on OECD 423.

Feeding behavior is regulated by a complex network of endogenous neuropeptides. In chordates, this role is suggested to be under the control of diverse factors including thyrotropin-releasing hormone (TRH). However, whether this regulatory activity of TRH is functionally conserved in non-chordate metazoans, and to what extent this process is underpinned by interactions of TRH with other neuropeptides such as cholecystokinin (CCK, known as a satiety signal), remain unclear.

Somatic cell nuclear transfer (SCNT) has been successfully employed across various mammalian species, yet cloned animals consistently exhibit low pregnancy rates, primarily due to placental abnormalities such as hyperplasia and hypertrophy. This study investigated the involvement of the Hippo signaling pathway in aberrant placental development in SCNT-induced bovine pregnancies. SCNT-derived cattle exhibited placental hypertrophy, including enlarged abdominal circumference and altered placental cotyledon morphology.
