Equol, a metabolite of soybean isoflavone daidzein, has been proven to have various bioactivities related to human health, but little is known on its antifungal activity to plant fungal pathogens. is a phytopathogenic fungus that causes rice blast, a devastating disease on rice. Here, we demonstrated that equol influences the development and pathogenicity of . Equol showed a significant inhibition to the mycelial growth, conidial generation and germination, and appressorial formation of . As a result, equol greatly reduced the virulence of on rice and barley leaves. The antifungal activity of equol was also found in several other plant fungal pathogens. These findings expand our knowledge on the bioactivities of equol.

Multiple endocrine neoplasia type 1 (MEN1) syndrome is an autosomal dominant disorder caused by a germline pathogenic variant in the MEN1 tumor suppressor gene. Patients with MEN1 have a high risk for primary hyperparathyroidism (PHPT) with a penetrance of nearly 100%, pituitary adenomas (PitAd) in 40% of patients, and neuroendocrine neoplasms (NEN) of the pancreas (40% of patients), duodenum, lung, and thymus. Increased MEN1-related mortality is mainly related to duodenal-pancreatic and thymic NEN.

Gut mucosal immunity of teleost is mainly governed by mucosa-associated lymphoid tissues (MALT) and indigenous microbiota on mucosal surfaces of gut tract, which can confer protection against pathogenic invasion. However, the probiotic features of bacterial isolates from gut tract of triploid cyprinid fish (TCF) were largely unclear. In this study, Lysinibacillus and Enterobacter strains were isolated for probiotic identification.

The role of Helicobacter pylori in the pathogenesis of peptic ulcers and gastric adenocarcinoma is widely known; however, it is not entirely understood how bacterial infection is closely related to the genesis of follicular gastritis and some types of gastric lymphoma. Diagnosing and pathogenic mechanisms follicular gastritis remain challenging. Therefore, this article aims to examine the role of H.

The neurobiological mechanisms driving the ictal-interictal fluctuations and the chronification of migraine remain elusive. We aimed to construct a composite genetic-microRNA model that could reflect the dynamic perturbations of the disease course and inform the pathogenesis of migraine. We prospectively recruited four groups of participants, including interictal episodic migraine (i.

Tuberculosis (TB) continues to be a major cause of death worldwide despite having an effective combinatorial therapeutic regimen and vaccine. Being one of the most successful human pathogens, retains the ability to adapt to diverse intracellular and extracellular environments encountered by it during infection, persistence, and transmission. Designing and developing new therapeutic strategies to counter the emergence of multidrug-resistant and extensively drug-resistant TB remains a major task.
