Cellulases are enzymes used in the hydrolysis of lignocellulosic residues for second-generation (2G) bioethanol production, low availability market, and high-cost impacts 40% total cost 2G production. Therefore, it is necessary to look sustainable alternatives its mainly produced by Aspergillus niger, their activity can be affected nitrogen concentration, use surfactants, carbon source, among o...

Episesamin is an isomer of sesamin, resulting from the refining process of non-roasted sesame seed oil. Episesamin has two methylendioxyphenyl groups on exo and endo faces of the bicyclic skeleton. The side methylendioxyphenyl group was metabolized by cytochrome-P450. Seven metabolites of episesamin were found in rat bile after treatment with glucuronidase/arylsulfatase and were identified usin...

Three new steroidal saponins were isolated from the roots of Smilax officinalis Kunth. Their structures were established as (3β,5β,22α,25S)-26-(β-D-glucopyranosyloxy)-22-hydroxyfurostan-3-yl O-α-L-arabinopyranosyl-(1→6)-O-[β-D-glucopyranosyl-(1→4)]-β-D-glucopyranoside, (3β,5α,22α,25S)-26-(β-D-glucopyranosyloxy)-22-hydroxyfurostan-3-yl O-α-L-arabinopyranosyl-(1→6)-O-[β-D-glucopyranosyl-(1→4)]-β-...

Five flavonoid glycosides and two derivatives were isolated from the herbs of Scorzonera austriaca Wild by silica gel column chromatography and preparative HPLC. Their structures were identified, using chemical and spectroscopic methods, as 5,7,4'-trihydroxyflavone 6-C-(2''-O-β-d-glucopyranosyl β-d-glucopyranoside) (1), 5,7,3',4'-tetrahydroxyflavone 6-C-(2''-O-β-d-glucopyranosyl β-d-glucopyrano...

Purpose –  The purpose of this study is to determine the effects perceived threat, severity, and self-isolation intention on impulsive buying during COVID-19 pandemic. Additionally, it aims mediating severity these relationships through serial mediation model. Design/Method/Approach  Online questionnaire form was used as data collection tool, convenience snowball sampling were methods. During ...

The minimal (N = 1) superparticle in three spacetime dimensions (3D) is quantized. For non-zero mass it describes a spin-1/4 semion supermultiplet of “relativistic helicities” (−1/4, 1/4). The addition of a parity-violating Lorentz–Wess–Zumino term shifts this to (β − 1/4, β + 1/4) for arbitrary β. For zero mass, in which case spin is not defined, the quantum superparticle describes a supermult...

OBJECTIVE The aim of the study was to determine the importance of β-hCG level on day 4 following methotrexate (MTX) administration, and the difference between β-hCG levels assessed on day 0 and day 4 in predicting treatment success. MATERIAL AND METHODS A total of 68 women with tubal pregnancy, treated with a single dose of MTX, were selected for this retrospective study. RESULTS The succes...
