Borrelia are fastidious bacteria some of which are difficult to grow in vitro. Here, we report a method for successful continuous in vitro cultivation of the emerging pathogen Borrelia miyamotoi. The type and quantity of serum as well as the atmosphere were critical for successful in vitro cultivation. Optimal growth was achieved using 50% pooled human serum and an atmosphere of 6% CO2.

Infertility has emerged as a significant global health concern. Assisted reproductive technology (ART) assists numerous infertile couples in conceiving, yet some experience repeated, unsuccessful cycles. This study aims to identify the pivotal clinical factors influencing the success of fresh embryo transfer of in vitro fertilization (IVF).

Cultivated Chinese cordyceps, an optimal substitute for the endangered wild resource, has recently been produced on a large scale. This work sought to explore the structural features and immunomodulatory activity of a novel low-molecular-weight polysaccharide (CSP1a, 15.7 kDa) isolated from cultivated Chinese cordyceps.

Background: Shell and pearl formation in bivalves is a sophisticated biomineralization process that encompasses immunological and mineralization aspects, particularly during shell repair and the initial stages of pearl cultivation when a nucleus is inserted. Here, we describe a novel C-type lectin, HcLec1, isolated and characterized from the freshwater pearl mussel Lea.
Methods: Immune challenge, RNA interference (RNAi) experiments, ELISA, and antibacterial assays were employed to investigate the role of HcLec1 in innate immunity.

Sages and their beneficial secondary metabolites have been used in conventional and traditional medicine in many countries, and are extensively studied for their health effects. However, to achieve high production levels, it is crucial to optimize the cultivation conditions. The aim of our study was to determine the optimal light-emitting diode (LED) treatment strategy for promoting plant growth and polyphenol biosynthesis in S.

Aspartate (Asp) metabolism-mediated antioxidant functions have important implications for neonatal growth and intestinal health; however, the antioxidant mechanisms through which Asp regulates the gut microbiota and influences RIP activation remain elusive. This study reports that chronic oxidative stress disrupts gut microbiota and metabolite balance and that such imbalance is intricately tied to the perturbation of Asp metabolism. Under normal conditions, in vivo and in vitro studies reveal that exogenous Asp improves intestinal health by regulating epithelial cell proliferation, nutrient uptake, and apoptosis.
