Aim: To investigate the effects of Hwangryunhaedok-tang (HHT) on gastrointestinal (GI) motility in mice.
Methods: The effects of a boiling water extract of HHT (HHTE) on GI motility were investigated by calculating percent intestinal transit rates (ITR%) and gastric emptying (GE) values using Evans Blue and phenol red, respectively, in normal mice and in mice with experimentally induced GI motility dysfunction (GMD). In addition, the effects of the four components of HHT, that is, Gardeniae Fructus (GF), Scutellariae Radix (SR), Coptidis Rhizoma (CR), and Phellodendri Cortex (PC), on GI motility were also investigated.
Results: In normal ICR mice, ITR% and GE values were significantly and dose-dependently increased by the intragastric administration of HHTE (0.1-1 g/kg). The ITR% values of GMD mice were significantly lower than those of normal mice, and these reductions were significantly and dose-dependently inhibited by HHTE (0.1-1 g/kg). Additionally, GF, CR, and PC dose-dependently increased ITR% and GE values in normal and GMD mice.
Conclusion: These results suggest that HHT is a novel candidate for the development of a gastroprokinetic agent for the GI tract.

Background/objective: There is limited knowledge on how diet affects the epigenome of children. Ultra-processed food (UPF) consumption is emerging as an important factor impacting health, but mechanisms need to be uncovered. We therefore aimed to assess the association between UPF consumption and DNA methylation in children.

Cyanobacteria strains have the potential to produce bioactive compounds that can be used in therapeutics and bioremediation. Therefore, compiling all information about these compounds to consider their value as bioresources for industrial and research applications is essential. In this study, a searchable, updated, curated, and downloadable database of cyanobacteria bioactive compounds was designed, along with a machine-learning model to predict the compounds' targets of newly discovered molecules.

Background: Sepsis is a significant cause of neonatal mortality. Both clinical and laboratory markers are often non- specific, and a blood culture contaminant may confuse management of the infant. This study aims to use an existing, inexpensive test, the neutrophil-to-lymphocyte ratio (NLR), to predict culture positivity and thus optimise antibiotic management.

Vulvovaginal candidiasis (VVC) is a common fungal infection caused primarily by Candida albicans, characterized by inflammation and discomfort, often requiring effective therapeutic strategies to reduce fungal load and inflammation. This study aimed to explore the therapeutic effects and underlying mechanisms of combining aspirin (ASP) and itraconazole (ITR) in treating vulvovaginal candidiasis (VVC) through activation of the NF-κB signaling pathway. Clinical isolates of Candida albicans were selected, and the M27-A4 microbroth dilution method was used for in vitro drug sensitivity testing.

Warfarin is used as anticoagulation for children for a wide range of cardiac indications but carries the disadvantage of requiring international normalised ratio monitoring and dose adjustment. Management of warfarin therapy is challenging due to its narrow therapeutic window and is further complicated in children by dietary changes, frequent illnesses, and developing systems of metabolism and haemostasis.A retrospective review was performed of patients' medical records to assess the indication for warfarin use, percentage of international normalised ratio values in target range (%ITR), and frequency of phlebotomy.
