Abstract Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of disease 19 (COVID-19) that was emerged as a new member coronaviruses since December 2019 in Wuhan, China and then after spread all continentals. Since SARS-CoV-2 has shown about 77.5% similarity to SARS-CoV, transcriptome immunological regulations expected have high percentage overlap with SARS-CoV. Results In this study, we applied single cell transcriptomics data human bronchial...
In this study, we show the synthesis of reduced graphene oxide/hydroxyapatite (rGO/HA) composites using a hydrothermal autoclave with argon-15% hydrogen gas injection. This both increases pressure and uses as reductive agent in process. The synthesized powders were then consolidated spark plasma sintering method. analysis samples included Vickers Indentation technique cell viability. results showed that injected gases produced higher crystallinity compared to without gases. Also, led...
Abstract Background Ataxia telangiectasia mutated (ATM) kinase plays a critical role in DNA double-strand break (DSB) repair. (A-T) patients exhibit abnormalities immunoglobulin isotype expression and class switch recombination (CSR). This study investigates the of residual ATM activity severity A-T disease. Methods with defined genetic diagnoses were classified based on CSR their medical complications. Isolated peripheral blood mononuclear cells from any patient evaluated before after...
<title>Abstract</title> In traffic crashes, mechanical loads are applied within milliseconds, resembling frequency sweeps in dynamic testing. While brain mechanics have been widely studied, the effect of temperature on tissue’s response remains unclear, with limited and inconsistent findings. Additionally, few studies examined how affects tissue model parameters, which could provide a more detailed analysis such effects. To address this, we conducted shear experiments bovine linear...
Introduction: Dicalcium phosphate dihydrate (DCPD) is a member of the family calcium phosphates (CP), which has many uses in bone cement. Recently, graphene and its derivatives have been studied to increase biological mechanical properties CP structures their results satisfactory. Objective: In this study, main objective investigate physical GO/DCPD powders, synthesized via simple precipitation method. Material Methods: Calcium nitrate tetrahydrate diammonium hydrogen were used as precursor...
Abstract Background Coronavirus disease 2019 (COVID-19) is an emerging zoonotic viral infection, which was started in Wuhan, China, December and transmitted to other countries worldwide as a pandemic outbreak. Iran one of the top ranked tables COVID-19-infected -mortality cases that make Iranian patients potential targets for diversity studies including epidemiology, biomedical, biodata, proteins computational modelling studies. Results In this study, we applied bioinformatic biodata mining...
Since recent research indicates that the addition of graphene increases mechanical and biological properties calcium phosphates simultaneously, oxide (GO) was used in this to enhance brushite cement. The main objective study is investigate mechanism nucleation growth crystals on GO sheets. Calcium nitrate tetrahydrate diammonium hydrogenphosphate were as phosphate precursors. chemical precipitation method sheets computer-assisted modeling understand process. results showed hybrid powders...
In this study, the two-state solvothermal method (180 °C) was used for synthesis of hydroxyapatite nanoparticles. The former is traditional (2, 4 h), and latter, with argon gas injection (10 bar). To synthesize powders, a solvent containing dimethylformamide, anhydrous ethanol, diethylene glycol, water used. Calcium nitrate tetrahydrate diammonium hydrogen phosphate were as calcium precursors, respectively. synthesized powders consolidated by high-frequency induction heat sintering method....
This study describes the occurrence of a silent mutation in RNA binding domain nucleocapsid phosphoprotein (N protein) coding gene from SARS-CoV-2 that may consequence to missense by onset another single nucleotide mutation.In DNA sequence isolated severe acute respiratory syndrome (SARS-CoV-2) Iran, for N protein was detected. The comparison Chinese and Iranian sequences displayed thymine (T) mutated cytosine (C), so "TTG" China changed "CTG" Iran. Both Iran have been encoded leucine. In...
The synthesis of nanocomposites containing hydroxyapatite and graphene sheets has received much attention recently. Therefore, strategies that improve their properties will be useful. aim this study was to investigate the effect diethylene glycol on characteristics hydroxyapatite-reduced oxide powders synthesized by a hydrothermal method (180 °C, 5 h) obtained spark plasma sintering (950 50 MPa). Graphene oxide, calcium nitrate tetrahydrate diammonium hydrogenphosphate were used as...
In order to investigate the effect of graphene nanoribbons on final properties hydroxyapatite-based nanocomposites, a solvothermal method was used at 180 °C and 5 h for synthesis nanoribbons–hydroxyapatite nanopowders by employing hydrogen gas injection. Calcium nitrate tetrahydrate diammonium hydrogenphosphate were as calcium phosphate precursors, respectively. To synthesize powders, solvent containing diethylene glycol, anhydrous ethanol, dimethylformamide, water used. Graphene oxide...

Objective: The main objective this study successfully synthesize uniform one dimensional HA nano-structures using a gram-scale hydrothermal batch process. Material Methods: Brushite used as precursor...
Abstract Background The inaccuracy of DNA sequence data is becoming a serious problem, as the amount molecular multiplying rapidly and expectations are high for big to revolutionize life sciences health care. In this study, we investigated accuracy from commonly used databases using carbonic anhydrase ( CA ) gene sequences generic targets. CAs ancient metalloenzymes that present in all unicellular multicellular living organisms. Among eight distinct families CAs, including α, β, γ, δ, ζ, η,...
An apparatus for measuring the wicking rise of water in fabrics has been developed and several types were examined. The method is based on electromagnetic field induction due to penetration into capillary spaces fabric samples. system coupled with a personal computer, distance as function time determined. Plain woven samples different weft yarn counts, density, type fiber blend results obtained by measurement compared vapor permeability index data test wettability textile same average...
Lipopolysaccharide-responsive, beige-like anchor protein (LRBA) deficiency is an autosomal recessive primary immunodeficiency disease characterized by a CVID-like phenotype, particularly severe autoimmunity and inflammatory bowel disease. This study was undertaken to evaluate radiation sensitivity in 11 LRBA-deficient patients. Therefore, stimulated lymphocytes of the studied subjects were exposed low dose γ-radiation (100 cGy) G2 phase cell cycle chromosomal aberrations scored. Lymphocytes...
Bolus is a material applied to the surface of patient for purposes such as compensating irregular contour, negating skin sparing, extra attenuating and etc. Unfortunately, because high cost super Flab (standard bolus material) in some clinics wet gauze, towel or other materials are used substitute superFlab bolus. In order survey function different dose distribution when bolus, TLD dosimetry was done on under (superFlab, gauze towel) at depths 6 MV, 18 MV ⁶⁰Co photon beams. showed that dis-...
