Abstract The prevention of implant-associated infections has been increasing clinically in orthopedic surgery. Hydroxyapatite with antibacterial properties was synthesized using a microwave-assisted combustion method. High crystallinity at low temperature can be achieved this hydroxyapatite exhibited superior clear zone for both Gram-positive and Gram-negative bacteria. Electron spin resonance (ESR) X-ray photoelectron spectroscopy (XPS) were used the radical investigation. application...

Porous hydroxyapatite (HAp) ceramics have been widely used in several biomedical applications. However, efforts to enhance the porous structure HAp often lead a decline their mechanical properties. In present study, by adding small amount of aluminum nitride (AlN) nanoparticles ceramics, we achieved formation with slight change grain size and The starting powder was obtained from natural source bovine bone. HAp/xAlN nanocomposites were fabricated simple conventional technique. 0.06 mol%...

Purple rice flour was modified using heat–moisture treatment (HMT) in three cycles an oven (OHMT) and autoclave (AHMT) at temperatures of 100 °C 120 °C, with moisture levels 20%, 25%, 30%. X-ray diffraction used to analyze the changes molecular structure. The swelling capacity, solubility, starch digestibility, including rapidly digestible (RDS), slowly (SDS), resistant (RS), were studied both native purple flour. bioactive compounds antioxidant activities also evaluated. Both OHMT AHMT...

Bioethanol is one of the most significant renewable fuels. The major sources bioethanol production are food crops such as corn, sugarcane, rice, wheat and sugar beet. However, utilization to produce could affect disrupt population ratio. To overcome these issues, lignocellulosic materials straw, grass crop residues has been developed for second-generation fuel, since those resources abundant, cheap renewable. Napier Pakchong 1 (NPG) residue a waste obtained from process biogas that can be...

Colored ZBP glasses with multiple catalytic properties have been successfully synthesized using a one-step melt-quenching technique.

The ethanolic rhizome extracts of Kaempferia species (K. angustiflora, K. elegans, galanga-1, galanga-2, galanga-3, marginata, parviflora, pulchra, and rotunda) were evaluated for their UV protective antioxidant properties. effective parviflora further isolated 18 pure compounds obtained. Flavokawain B (1), a chalcone found in exhibited the most UVA UVB protection, more potent than commercial sunscreens. Compound 1 demonstrated highest activities ABTS, DPPH, FRAP assays.Abbreviations: ABTS:...

Essential oils from the aerial parts of four Elsholtzia species; stachyodes, communis, griffithii and beddomei were obtained by steam distillation their chemical components analysed gas chromatography-mass spectrometry (GC-MS). Principle Component Analysis was used to identify variations in essential these plants, which could be categorised into two groups according main are acylfuran derivatives oxygenated monoterpenes. Additionally, anti-acne inducing bacterial activity against...

Four types of traditional Thai rice—polished, black fragrant, glutinous and rice—were separately used as raw material for vinegar production. During alcohol fermentation, using enriched baker’s dried yeast (S. cerevisiae) a starter culture gave the highest ethanol content over 7 days fermentation. The conversion to acetic acid production by Acetobacter pasteurianus TISTR 102 was performed 25 days. amount detected with rice fermentation (6.68% w/v). biological properties vinegars were...

The CSO additive enhanced the electrical and mechanical properties of 0.99BNKT–0.01BMN ceramics. Biological tests on x = 0.02CSO samples showed moderate apatite formation in SBF test good cell viability cytotoxicity test.

Biotransformations of stemofoline (1a), (2′S)-hydroxystemofoline (2a), (11Z)-1′,2′-didehydrostemofoline (3a) and stemocurtisine (4) were studied through fermentation with Cunninghamella elegans TISTR 3370. Three new derivatives; (6 R)-hydroxystemofoline (1b), (2′S, 6 R)-dihydroxystemofoline (2b) (11Z,6R)-1′,2′-didehydro-6-hydroxystemofoline (3b), together the known compound 1′,2′-didehydrostemofoline-N-oxide (3c), produced by C-hydroxylation N-oxidation reactions. Stemocurtisine was not...

This research study was conducted with the greater aim of understanding potentially efficient fungal cellulase production from low cost lignocellulosic substrate.  has attempted to use pretreated corn cobs as a substrate for via solid-state fermentation (SSF) by white rot fungus, Pycnoporus coccineus . The effects moisture content, incubation temperature, initial pH value and nitrogen source on  biosynthesis were observed optimal in flask fermentors. filter paper activity (FPase;...

This research evaluated the role and feasibility of granular nanocellulose particles (GNC) from sugarcane bagasse obtained enzymatic hydrolysis in reducing lipid digestibility permeability vitro simulated gastrointestinal (GI) system. GNC concentration (0.02%, w/v) had significantly affected released free fatty acid (FFA) reduction approximately 20%. The Pick-ring emulsion olive oil simulation mixture revealed higher droplet size distribution stability initial stage than vortexed formation....

In the present work, characteristic of β-tricalcium phosphate (β-TCP) powder was investigated for its film coating on a Ti6Al4V metallic biomaterial. The β-TCP synthesized by solid-state reaction technique at different temperatures. formed temperatures 900-1000 oC, while α-tricalcium (α-TCP) occurred higher (≥1000 oC). Crystallite size increased with increasing temperature, but it decreased than 1000 oC due to formation α-TCP. Furthermore, amount α-TCP phase temperature. However, maximum...
