In the past few years, research has focused on design and development of natural polymers-based hydrogels owing to their inherent features as well numerous application ranges. this context, polysaccharide-based have attracted significant interest mainly due superior physicochemical biological characteristics. However, these types biomaterials 'suffer' from some problems. This review aims give an update diverse optimization strategies used improve properties based polysaccharides for...
Application of wound-healing/dressing biomaterials is amongst the most promising approaches for wound repair through protection from pathogen invasion/contamination, maintaining moisture, absorbing exudates, modulating inflammation, and facilitating healing process. A wide range materials are used to fabricate biomaterials. Active wound-healing/dressings next-generation alternatives passive biomaterials, which provide a physical barrier induce different biological activities, such as...
For bone tissue engineering, stem cell-based therapy has become a promising option. Recently, cell transplantation supported by polymeric carriers been increasingly evaluated. Herein, we encapsulated human olfactory ectomesenchymal cells (OE-MSC) in the collagen hydrogel system, and their osteogenic potential was assessed vitro vivo conditions. Collagen type I composed of four different concentrations (4 mg/mL, 5 6 7 mg/mL). SDS-Page, FTIR, rheologic test, resazurin assay, live/dead SEM were...
Apple pomace (AP) from the food industry is a mixture of different fractions containing bioactive polyphenolic compounds. This study provides systematic approach toward recovery and evaluation physiochemical biological properties compounds AP. We studied subcritical water extraction (SCW) solvent with ethanol four AP pulp, peel, seed, core, stem (A), peel (B), seed core (C), pulp (D). The method at optimum condition resulted in total (TPC) 39.08 ± 1.10 mg GAE per g on dry basis compared to...
Gastric cancer (GC) is a significant global health issue with high incidence rates and poor prognoses, ranking among the top prevalent cancers worldwide. Due to undesirable side effects drug resistance, there pressing need for development of novel therapeutic strategies. Understanding interconnectedness JAK2/STAT3/mTOR/PI3K pathway in tumorigenesis role Astaxanthin (ASX), red ketocarotenoid member xanthophylls potent antioxidant anti-tumor activity, can be effective treatments. This study...
Carotenoids are of great interest in many scientific disciplines because their wide distribution, diverse functions and interesting properties. The present report describes a new natural source for carotenoid production.Halorubrum sp., TBZ126, an extremely halophilic archaeon, was isolated from Urmia Lack following culture water sample on marine agar medium incubation at 30 °C. Then single colonies were cultivated broth media. After that the cells collected carotenoids extracted with...
In the current paper, we fabricated, characterized, and applied nanocomposite hydrogel based on alginate (Alg) nano-hydroxyapatite (nHA) loaded with phenolic purified extracts from aerial part of Linum usitatissimum (LOH) as bone tissue engineering scaffold. nHA was synthesized wet chemical technique/precipitation reaction incorporated into Alg filler via physical cross-linking. The characterizations (SEM, DLS, Zeta potential) revealed that possess a plate-like shape nanometric dimensions....
In a retrospective investigation, the medical files of patients who, between 1992 and 2006, underwent surgery for treatment cystic echinococcosis (CE) in one three university hospitals Hamedan province, western Iran, were explored. Of 179 involved, 44.1% male 55.9% female, giving male/ female ratio 0.79. The mean annual surgical incidence CE catchment areas study was estimated to be 1.33 cases/100,000. Although most Hamedan's population is urban (53.02% at last census, 1997), (57.5%) lived...
Exopolysaccharides (EPSs) are high-value functional biomaterials mainly produced by bacteria and fungi, with nutraceutical, therapeutic industrial potentials.This study sought to characterize assess the biological properties of EPS yeast Papiliotrema terrestris PT22AV.After extracting yeast's DNA its molecular identification, from P. PT22AV strain was extracted physicochemical (structural, morphological, monosaccharide composition weight) were characterized. The EPS's in vitro activities...
Carotenoids are one of the most diverse and broadly distributed classes pigments in nature with a high number biotechnological applications.Carotenoids have broad range functions, especially relation to human health their role as biological antioxidants.The increasing demand for consumption natural carotenoids has raised interest bio-production.The objective present study was analysis environmental factors (temperature, pH salinity) through response surface methodology (RSM) on total...
Purpose: Due to the potential industrial and therapeutic applications of yeast exopolysaccharides (EPSs), there has been an increasing demand assess these biopolymers with improved characteristics. This study aimed characterize EPSs from Rhodosporidium babjevae (ATCC 90942 IBRC-M 30088) as well evaluate their possible antioxidant, emulsifying antiproliferative activities. Methods: was cultured for 5 days following isolation supernatant, precipitated adding cold absolute ethanol freeze-dried....
Loss of skin integrity can lead to serious problems and even death. In this study, for the first time, effect exopolysaccharide (EPS) produced by cold-adapted yeast R. mucilaginosa sp. GUMS16 on a full-thickness wound in rats was evaluated. The strain’s EPS precipitated adding cold ethanol then lyophilized. Afterward, with polycaprolactone (PCL) gelatin fabricated into nanofibers two single-needle double-needle procedures. rats’ wounds were treated Hematoxylin eosin (H&E) Masson’s...
Exopolysaccharides (EPSs) are important biopolymers with diverse applications such as gelling compounds in food and cosmetic industries bio-flocculants pollution remediation bioplastics production. This research focuses on enhancing crude EPS production from Rhodotorula mucilaginosa sp. GUMS16 using the central composite design method which five levels of process variables sucrose, pH, ammonium sulfate were investigated sucrose serving carbon nitrogen sources during microbial incubation.
