Background While electrospun materials have been frequently used in tissue engineering no wound dressings exist that significantly improved wound healing effectively. Methods We succeeded to fabricate three-dimensional (3D) electrospun poly(D,l-lactide) (PLA) fiber mats into which nanospheres, formed from amorphous calcium polyphosphate (polyP) nanoparticles (NP) and encapsulated retinol ("re...

Inorganic polyphosphates (PolyP) are linear polymers of few to several hundred orthophosphate residues, linked by energy-rich phosphoanhydride bonds. Four isolates had been screened from soil sample. By MALDI-TOF analysis, they were identified as Bacillius cereus, Acinetobacter towneri, B. megaterium and B. cereus. The production of PolyP in four isolates was studied in phosph...

background: routine screening colonoscopy is on the rise and pathologists have to deal with the ever larger numbers of excised colonic polyps. it is very important to optimize the patients’ individual treatment and further surveillance. pathologists play a critical role in management, as most of the clinical decisions concerning colonic polyp management are based on pathologic findings. one of ...

A major impediment to understanding the biological roles of inorganic polyphosphate (polyP) has been the lack of sensitive definitive methods to extract and quantitate cellular polyP. We show that polyP recovered in extracts from cells lysed with guanidinium isothiocynate can be bound to silicate glass and quantitatively measured by a two-enzyme assay: polyP is first converted to ATP by polyP k...

background and objectives: nasal polyposis is a diseases resulting from complex pathogenetic mechanisms. some studies showed that tgfβ1 had significant role in this pathogenesis. in this study, we investigated the roe of cytokines and mediators in polyp development. material and methods: in this case- control study, healthy nasal mucosal samples were obtained from 24 people undergoing septoplas...

Sphenochoanal polyp is a rare form of choanal polyp. If unrecognised, they can be mistaken for an antrochoanal polyp. This will result in unnecessary exploration of the maxillary sinus, and a failure to remove the sphenoidal component of the sphenochoanal polyp. Adequate preoperative evaluation with computed tomography or magnetic resonance is mandatory to ascertain the correct diagnosis, and t...

Abstract. One of the important things that must be considered by teacher in learning process is to know advance characteristics students. Learning style modality one how students and recognizes their personality process. The type research used this study was a survey using qualitative descriptive approach. population were all high school class IX, Jeneponto Regency, for 2021/2022 academic year....
