Glycemic Control and Oral Health Outcomes in Patients With Diabetes: Insights From a Nationwide Korean Survey.

Background: Diabetes is recognized as a risk factor for various inflammatory conditions, including periodontitis. There exists a bidirectional relationship between glycemic control and oral health in individuals with diabetes. This study aimed to analyze the link between glycemic control and oral health status among Korean patients with diabetes.

Initial treatment response and short-term mortality of spontaneous bacterial peritonitis in cirrhotic patients with hepatocellular carcinoma.

This study aimed to investigate the initial treatment response and short-term mortality of spontaneous bacterial peritonitis (SBP) in cirrhotic patients with hepatocellular carcinoma (HCC) compared with those without HCC. A total of 245 patients with liver cirrhosis diagnosed with SBP between January 2004 and December 2020 were included. Of these, 107 (43.

Assessment of the Aromatase Inhibitory Activity of Ma-Huang-Tang (MHT) and Its Active Compounds.

Aromatase, a cytochrome P450 enzyme that converts androgens into estrogens, is an important drug target for hormone-dependent diseases. The purpose of this study was to elucidate the aromatase inhibitory effects of Ma-Huang-Tang (MHT), a traditional Korean herbal medicine prescription, and to identify its active ingredients. In this study, the inhibitory effect of MHT on aromatase activity was observed using dibenzylfluorescein (DBF) and KGN cells, and the dose-dependent effect of MHT was verified (IC values of 251 g/mL and 246 g/mL as determined by the two methods, respectively).

Tetragonia tetragonioides (Pall.) Kuntze Regulates Androgen Production in a Letrozole-Induced Polycystic Ovary Syndrome Model.

(Pall.) Kuntze (TTK) is a medicinal plant traditionally used to treat various diseases such as diabetic, inflammatory, and female-related disorders. Polycystic ovary syndrome (PCOS) is a common endocrinological disorder in women of reproductive age, and hyperandrogenism is a prominent feature of PCOS resulting in anovulation and infertility.

Lignans from the stems and leaves of Brandisia hancei and their effects on VEGF-induced vascular permeability and migration of HRECs and DLAV formation in zebrafish.

In our continuing search for novel antiangiogenic agents, a new lignan glycoside, (7R,8R)-1-(4-O-β-d-glucopyranosyl-3-methoxyphenyl)-2-{2-methoxy-4-[1-(E)-propene-3-ol]-phenoxyl}-propane-1,3-diol (1), along with three known lignans (2-4), were isolated from the 80% EtOH extract of Brandisia hancei stems and leaves. These isolates (1-4) were subjected to an in vitro bioassay to evaluate their effects on vascular endothelial growth factor (VEGF)-induced vascular permeability and migration of human retinal endothelial cells (HRECs). Of the compounds tested, compound 1 resulted in the greatest reduction in VEGF-induced vascular permeability by about 31.

Caffeoylated phenylpropanoid glycosides from Brandisia hancei inhibit advanced glycation end product formation and aldose reductase in vitro and vessel dilation in larval zebrafish in vivo.

In our continuing efforts to identify effective naturally sourced agents for diabetic complications, five caffeoylated phenylpropanoid glycosides, acteoside (1), isoacteoside (2), poliumoside (3), brandioside (4), and pheliposide (5) were isolated from the 80% EtOH extract of Brandisia hancei stems and leaves. These isolates (1-5) were subjected to an in vitro bioassay evaluating their inhibitory activity on advanced glycation end product formation and rat lens aldose reductase activity. All tested compounds exhibited significant inhibition of advanced glycation end product formation with IC50 values of 4.

Proanthocyanidins from Spenceria ramalana and their effects on AGE formation in vitro and hyaloid-retinal vessel dilation in larval zebrafish in vivo.

Three new A-type proanthocyanidins (1-3), ent-epiafzelechin-(2α→O→7,4α→8)-ent-afzelechin 3'-O-β-D-glycopyranoside (1), ent-epiafzelechin-(2α→O→7,4α→8)-ent-epiafzelechin-(2α→O→7,4α→8)-ent-afzelechin (2), and ent-epiafzelechin-(2α→O→7,4α→8)-ent-epicatechin-(2α→O→7,4α→8)-ent-afzelechin (3), and three known compounds (4-6) were isolated from the whole plant of Spenceria ramalana. The structures of the new proanthocyanidins were established by spectroscopic and chemical studies. The inhibitory effects of compounds 1-6 on the formation of advanced glycation end products were examined in vitro.

Effects of Allium victorialis leaf extracts and its single compounds on aldose reductase, advanced glycation end products and TGF-β1 expression in mesangial cells.

Background: Accumulating evidences suggest that aldose reductase (AR) inhibitors and advanced glycation end product (AGE) formation inhibitors may prevent chronic hyperglycemia-induced long-term complication in diabetes. Transforming growth factor-beta1 (TGF-β1) plays an important role in the development of diabetic nephropathy. Allium species have been utilized in folk medicine throughout the world for the treatment of various physical disorders.
