two peroxidases (ec. 1.11.1.7), pod i and pod ii were purified from the roots of cultivatedraphanus sativus l. var. cicil by one step ion-exchange chromatography after fractionation by acetone. the molecular weight of these enzymes were 43000 and 41000 daltons and rz 1.2 and 2.0 for pod i and pod ii, respectively. both enzymes consisted of a single polypeptide chain on sds-page. the maximum act...

Introduction: Recently Cerium oxide nanoparticles (CONPs) are being checked as interventional treatments in biological systems. The scavenging of free radicals by nanoparticles performance is the inhibition of Reactive Oxygen Species (ROS). Ionizing radiations can prevent the proliferation and differentiation of cells and even cause apoptosis. CONPs, as radioprotection, can pro...

Back Cover In article number 2200325, Wang and coworkers present a camera-free intrinsic mechanical cytometry (CFIMC) for high-throughput single-cell characterization. The strategy of CFIMC adopts framework that couples the impedance electrodes with constriction channel spatially, so signals contain dynamic deformation cell squeezing through channel.

in this work, we report high biological performance of silicon substituted nano hydroxyapatite (nha) prepared by immersion of calcium phosphate and sodium silicate as precursors in simulated body fluid (sbf) solution for 24, 36, 48 and 72 hrs at 37°c. characterization and chemical analysis of the synthesized powders were performed by fourier transform, infrared spectroscopy (ft-ir), x-ray powde...

background: lectins the multivalent carbohydrate binding proteins are also employed to ascertain differentiation and characterization of the specific cell surface carbohydrate ligands/ receptors of different cell types including spermatozoa and posses novel biomedical importance. objective: sf50 the sialic acid specific lectin was employed on goat cauda epididymal spermatozoa to investigate its...

Abstract Cell-aware test (CAT) explicitly targets faults caused by defects inside library cells to improve quality, compared with conventional automatic pattern generation (ATPG) approaches, which target only at the boundaries of cells. The CAT methodology consists two stages. Stage 1, based on dedicated analog simulation, characterization per cell identifies cell-level detects cell-internal de...

A standardized microstructure characterization tool for solid oxide cell (SOC) electrodes is presented, allowing the automatic determination of a large number characteristics relevant performance.

brucellosis, produced by brucella species, is a disease that causes severe economic losses for livestock farms worldwide due to serious economic and medical consequences of this disease, many efforts have been made to prevent the infection through the use of recombinant vaccines based on brucella outer membrane protein (omp) antigens. in the present study, a wide range of on-line prediction sof...

introduction: as the ability to repair cartilage tissue in body is limited, finding a suitable method for cartilage regeneration has gained the attention of many scholars. for this purpose, scaffold structure and morphology, along with cell culture on it, can be a novel method to treat cartilage injuries, osteoarthritis. methods: in this study, polyhydroxybutyrate (phb) is selected as the scaff...

Cell Chirality Assays In article 2101088, Wan and co-workers review the characterization of cellular chirality or handedness which can be used for cytotoxicity assessment. The cells display directional alignment within well-confined geometric boundaries in normal conditions, such as ring-shaped micropatterns. toxic environments, cell may exhibit a reversed bias become randomized. This new type ...
