BACKGROUND Oral leukoplakia (OL) is the most typical potentially malignant disorder of the oral mucosa. We aimed to evaluate the clinical outcome of oral leukoplakia treated with several types of lasers and with the use of quantic molecular resonance (QMR) lancet, in terms of recurrence rate. MATERIAL AND METHODS Eighty-seven previously untreated OL (52 occurring in females and 35 in males, m...

Dietary intervention studies suggest that flavan-3-ol intake can improve vascular function and reduce the risk of cardiovascular diseases (CVD). However, results from prospective studies failed to show a consistent beneficial effect. Associations between flavan-3-ol intake and CVD risk in the Norfolk arm of the European Prospective Investigation into Cancer and Nutrition (EPIC-Norfolk) were inv...

The total phenol content and the anti-acetylcholinesterase activity were compared in olive leaf (OL) extracts obtained using both subcritical water extraction (SbWE) conventional solvent (ethanol-water). method proposed by Ellman (in vitro) was used to study inhibitory of acetylcholinesterase (AChE). phenolic compounds AChE activities OL varied depending on method. Thus, extract technique (220 ...

O experimento foi instalado em área renovação canavial, localizada Campina Verde – MG, na safra 2021/22. delineamento experimental utilizado blocos casualizados, quatro repetições. Os tratamentos foram cinco rasteiro, sendo uma cultivar (BRS 423 OL) e linhagens (2717 OL, 2173 2094...

The COVID-19 pandemic has forced universities to make a radical switch from face-to-face traditional teaching (TT) completely online learning (OL). Thus, many studies proposed the proper OL environment for specific subject and evaluated its effectiveness. However, few have empirically compared with TT determine which better More importantly, an self-regulated (SRL) ability of student interactiv...

The biotransformation of partheniol by the fungus Calonectria decora ATCC 14767, produced six metabolites. These metabolites are; aromadendr-1(10)-en-8alpha -ol; 5(9),6-tricyclohumul-1(10)-en-8alpha-ol; 4,15-didehydro-6-bicyclohumulan-8a,10alpha-diol; 5(9),6-tricyclohumulan-4a,8alpha-diol; maalian-la,8alpha-diol and 14-epi-1(4)-epoxymaalian-8alpha-ol. The identities of these metabolites were es...

Three new triterpenoid aglycones named Philinopgenin A (1), B (2), and C (3) were isolated from the acid hydrolysate of the crude glycoside mixture prepared from the whole sea cucumber Pentacta quadrangulasis Lesson. The corresponding structures were determined as 16β-acetoxyholosta-8(9), 24(25)-diene-3β-ol (1), 20, 25-epoxy-lanosta-9(11)-ene-3β-ol 18(16)–lactone (2) and 16β-acetoxyholosta-9(11...

The essential oils from rhizomes of Rhodiola crenulata and R. fastigiata in eastern Tibet were analyzed by using GC-MS. The major constituents were geraniol (53.3%), n-octanol (13.4%), 2-methyl-3-buten-2-ol (10.8%), citronellol (5.3%), 3-methyl-2-buten-1-ol (4.0%), myteol (3.0%), and linalool (2.4%) for R. crenulata and geraniol (45.3%), n-octanol (12.3%), 2-methyl-3-buten-2-ol (8.0%), linalool...

A simplified method is described for the preparation of 14 alpha-hydroxymethyl-4,4-dimethyl-5 alpha-cholest-8-en-e beta-ol, 14 alpha-hydroxymethyl-4,4-dimethyl-5 alpha-cholest-7-en-3 beta-ol, and 14 alpha-hydroxymethyl-4,4-dimethyl-5-alpha-cholest-6-en-3 beta-ol from commercial lanosterol. This method represents a modification of the approach introduced by Fried and co-workers (Fried, J., J. W....
