Urinary crystals with various sizes are present in healthy individuals and patients with kidney stone; however, the cellular uptake mechanism of calcium oxalate of various sizes has not been elucidated. This study aims to compare the internalization of nano-/micron-sized (50 nm, 100 nm, and 1 μm) calcium oxalate monohydrate (COM) and dihydrate (COD) crystals in African green monkey renal epithe...

Radiotherapy may compromise the integration of implant and cause implant loss. Implant surface modifications have the possibility of promoting cell attachment, cell growth, and bone formation which ultimately enhance the osseointegration process. The present study aimed to investigate the effects of calcium phosphate nanocrystals on implant osseointegration in irradiated bone. Sixteen rabbits w...

A bioactive composite of nano calcium-deficient apatite (n-CDAP) with an atom molar ratio of calcium to phosphate (Ca/P) of 1.50 and poly(ɛ-caprolactone)-poly(ethylene glycol)-poly(ɛ-caprolactone) (PCL-PEG-PCL) was synthesized, and a composite scaffold was fabricated. The composite scaffolds with 40 wt% n-CDAP contained well interconnected macropores around 400 μm, and exhibited a porosity of 7...

To improve the aging resistance of bioasphalt and explore impact organic nano calcium carbonate (CaCO3) on bioasphalt, thin-film oven test (TFOT), basic property test, rheological four components infrared spectrum were used to study with different nano-CaCO3 contents. The results show that addition increases residual penetration, ductility, softening point bioasphalt. Within range dosage, great...

Multiphasic calcium phosphate powders were synthesized by the acidic route, using lactic acid as a chelating agent that allows production of stable and rich solution ions at room temperature. After pH adjusting, without varying concentrations precursor solution, XRD FTIR analyses showed different CaP phases before after heat treatment 1000 °C. At 5, brushite plate-like particles produced, while...

Background: To evaluate and compare the microhardness of deciduous teeth treated with nano-hydroxyapatite and calcium sucrose phosphate after iron drop exposure. Material and Methods: Twenty healthy anterior deciduous teeth were collected and stored in 0.9% saline solution at room temperature. All the teeth were immersed in artificial saliva in an incubator shaker at 37° for an hour and then su...

Abstract In the spring of 2022, researchers from University Mosul’s Faculty Agriculture and Forestry conducted an experiment on a vegetable field. this experiment, we looked at three variables: first, effects two different potato cultivars (Montreal EL-Beida). For second part, soaked potatoes in solution potassium humate with concentration (0, 0.5, 1 g L -1 ). Therefore, had 18 treatments (2 3 ...
