During development, the zebrafish embryo relies on its yolk sac as a nutrient source. Here, we present a protocol for modifying the free fatty acid (FFA) and triacylglycerol (TAG) content of the zebrafish yolk sac by microinjection. We describe steps for needle and injection mold preparation, FFA and TAG solution preparation, and microinjection. This protocol can elucidate how excesses of FFA and TAG affect development and modify the transcriptome of zebrafish embryos. For complete details on the use and execution of this protocol, please refer to Konadu et al. .

Hepatitis C virus (HCV) elimination in the care cascades for patients receiving invasive procedures remains elusive. This study aimed to evaluate the efficacy of HCV-free Endoscope Procedures Project (CEPP) in the effort toward hospital HCV micro-elimination in Taiwan. An electronic medical record (EMR)-based remind system was introduced into gastrointestinal, surgical, urological, and gynecological departments prior to the endoscopy procedures.

Cyanobacteria are widespread, photosynthetic, gram-negative bacteria that generate numerous bioactive secondary metabolites complex biosynthetic enzymatic machinery. The model cyanobacterium sp. strain PCC 7002, hereafter referred to as PCC 7002, contains a type I polyketide synthase (PKS), termed olefin synthase (OlsWT), that synthesizes 1-nonadecene and 1,14-nonadecadiene: α-olefins that are important for growth at low temperatures.

Acetyl coenzyme A (acetyl-CoA), a pivotal regulatory metabolite, is a product of numerous catabolic reactions and a substrate for various anabolic responses. Its role extends to crucial physiological processes, such as glucose homeostasis and free fatty acid utilization. Moreover, acetyl-CoA plays a significant part in reshaping the metabolic microenvironment and influencing the progression of several diseases and conditions, including cancer, insulin resistance, diabetes, heart failure, fear, and neuropathic pain.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a prevalent hepatic disorder worldwide. Arachidonic acid 15-lipoxygenase (ALOX15), an enzyme catalyzing the peroxidation of polyunsaturated fatty acids, plays a crucial role in various diseases. Here, we sought to investigate the involvement of ALOX15 in MASLD.

Lipases are enzymes that have an important role in the industry for their wide use, giving rise to a great interest in industrial bioprocesses due to their versatility. One of the applications is the enzymatic hydrolysis of waste oils. This work consists of evaluating the production of lipases using several concentrations of residual frying oil (RFO) and different pHs, through ANOVA analysis.
