Epigallocatechin gallate (EGCG) is the main bioactive component of green tea. Through screening of a small library of natural compounds, we discovered that EGCG inhibits cystathionine β-synthase (CBS), a major HS-generating enzyme. Here we characterize EGCG's mechanism of action in the context of CBS-derived HS production. Read More

Background: Slow colon transit and visceral hypersensitivity are recognized as major pathophysiological mechanisms in irritable bowel syndrome with constipation (IBS-C). However, there is a lack of therapies targeting both abdominal pain and colonic motility. This study was designed to investigate the long-term effects and possible mechanisms of transcutaneous electrical acustimulation (TEA) in patients with IBS-C. Read More

Aroma extract dilution analysis was performed on volatile fractions extracted from a freshly prepared (DHP) tea infusion using solvent-assisted flavor evaporation, yielding 65 odor-active domains with flavor dilution factors ranging between 32 and 32,768. In addition, six aromatic substances were captured by headspace analysis. Quantitation of 54 compounds by an internal standard method and stable isotope dilution assays revealed that the concentrations of 32 odorants exceeded their respective orthonasal odor threshold values in tea infusion.

In the study, we examined in detail the effect of dehydrating using natural drying in the shade, convection drying, and microwave drying, which are the most widely used techniques, especially for tea and spices, both in practice and in theory, on the protein, and mineral composition of rosemary leaves. Also, we determined the color parameters, which are the reason for the selection because it creates the allure for spices. In microwave drying at 600 W, we obtained results close to fresh rosemary in all color parameters, especially brightness and greenness. Read More

This paper investigates the impact of subcomponents of collaboration: information sharing, connectivity, coordination, integration, and visibility on the tea supply chain resilience of Sri Lanka during the Covid-19 pandemic. This research was carried out with mixed methods. The quantitative approach adopted a systematic random sampling technique to determine the sample size ( = 137), whereas the qualitative study used the purposive sampling technique to determine the sample size ( = 6).
