A new heterocyclic azo dye ligand (L) was synthesized by the combination of 4-amino antipyrine with 4-aminophenol. The Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), and Cd(II) complexes were in excellent yields. metal chelate structures elucidated using elemental analyses, FT-IR, 1H-NMR, mass, magnetic moment, diffused reflectance spectral thermal analysis (TG-DTG), molar conductivity measurement. According to FT-IR study, exhibited neutral tri-dentate behavior, binding ions N,...
Spatiotemporal changes in land surface temperature (LST) over South Asia were estimated using MODIS (moderate resolution imaging spectroradiometer) data from 2000 to 2021. We calculated the monthly and annual LST trends magnitudes by applying Mann–Kendall test Sen's slope estimator at both ecoregion pixel level. More ecoregions experienced daytime cooling than warming. Central west showed highest December compared nighttime warming central northwest July September. Nineteen demonstrated 99%...
Digital Elevation Models (DEMs) contribute to geomorphological and hydrological applications. DEMs can be derived using different remote sensing-based datasets, such as Interferometric Synthetic Aperture Radar (InSAR) (e.g., Advanced Land Observing Satellite (ALOS) Phased Array type L-band SAR (PALSAR) Shuttle Topography Mission (SRTM) DEMs). In addition, there is also the Surface Model (DSM) from optical tri-stereo ALOS Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM)...
Abstract Background Facial resorption of maxillary alveolar ridges is a challenging situation for implant rehabilitation, which mandates preparatory surgery bone augmentation. Guided regeneration using 1:1 mixture autogenous particulate and anorganic bovine mineral (ABBM) showed reliable outcomes in treating horizontally deficient ridges. Methods Twenty‐eight patients were randomly assigned into two groups; the control group, ABBM was covered with native collagen membrane, while study it...
Precipitation is a critical variable for comprehending various climate-related research, such as water resources management, flash flood monitoring and forecasting, climatic analyses, hydrogeological studies, etc. Here, our objective was to evaluate the rainfall estimates obtained from Global Mission (GPM), Satellite Mapping of (GSMaP) constellation over an arid environment like Sultanate Oman that characterized by complex topography extremely patterns. Satellite-based Estimates (GSPEs) can...
A novel azo dye ligand was created by diazotizing 4‐aminoantipyrine and then coupling it with 2‐aminophenol as part of a methodical investigation physiologically active compounds, 4‐aminoantipyrine. The complexes containing Cr(III), Fe(III), Mn(II), Co(II), Ni(II), Zn(II), Cu(II), Cd(II) were from the target (L). structures metal verified elemental analyses, thermogravimetric analysis–difference thermogravimetry (TGA‐DTG), conductivity measurements, infrared (IR), UV–Vis, 1 H‐nuclear...
ABSTRACT Background The horizontally insufficient posterior mandibular ridge frequently restrains dental implant insertion. Patients and Methods A modified split procedure was innovated to separate, convey laterally, fix the buccal cortical plate in 20 patients with horizontal alveolar deficiency. Meanwhile, intercancellous space obliterated autogenous bone particulates for test group Anorganic bovine mineral (ABBM) those of control group. Following a comparison gain histomorphometric area...
The aim of the study was to evaluate bone quality and quantity after threedimensional augmentation vertically horizontally atrophied maxillary ridges using marrow aspirate concentrate (BMAC) xenograft versus autograft xenograft, both pre-bent titanium mesh over a virtually augmented model. 10 fully edentulous patients with severe vertical horizontal loss were recruited. Virtual done for deficient ridge produce models pre-bending meshes preoperatively. In side, loaded mix BMAC from anterior...
Abstract Background Several biomaterials have been suggested to augment the jumping gap during immediate implant placement. Purpose The aim of this study was compare effect xenograft or platelet derived growth factor (PRF) graft in placement maxillary premolar region. Materials and methods Twenty patients underwent atraumatic extraction followed by were equally divided into two groups. first group received as a filling material. second PRF gap. All preoperative, postoperative, 6 months...
Using the sandwich osteotomy technique in posterior mandible is delicate. This study aimed to assess safety and amount of bone gain using a full digital workflow versus conventional procedure.
Abstract Background Calvarial bone grafts have been one of the grafting options that provides predictable results for three‐dimensional reconstruction severely atrophied ridges owing to their low resorption and rapid revascularization, thus providing adequate volume implant insertion. The aim this study was introduce a computer‐guided technique calvarial graft harvest minimize complications known with from donor site. Materials Methods Eight patients, suffering atrophied, completely...
The objective was to compare Cobb angle measurements performed using an Oxford Cobbmeter and digital computer software (Surgimap) in a series of 83 adolescent idiopathic scoliosis (AIS) patients.Two independent observers measured the angles for 123 curves on consecutive long radiographs patients with AIS both (Surgimap). were repeated week. Curves classified according severity into mild, moderate, severe. results statistically analyzed intraobserver interobserver reliability.The mean 48.12°...
New technologies look for practical applications and complex clinical problems search innovations able to address them.This convergent course of needs technological innovation laid foundation progress success modern health care.Our review looks at the present status future concepts parathyroid surgery in relation important developments last few decades.We focus on describing how operations have been transformed by more accurate imaging discuss impact intra-operative PTH monitoring, a...
The primary goal of maxillary alveolar cleft reconstruction in patients with lip/palate at the phase mixed dentition is to build bone area which turn allows closure oronasal fistula, establishes arch continuity, and improve stability. This study aimed evaluate double iliac corticocancellous plates grafting technique for initial grafting.This prospective was conducted on 12 consecutive unilateral complete previous lip palate corrective surgery.For all patients, crest graft harvested cut into...
The brain is a particularly rare site of metastasis from papillary microcarcinoma, with only few cases described in the literature. We present case 59-year-old man who presented seizures and dysphasia due to left frontal lobe cystic mass, which was excised turned out on histopathology be thyroid origin. Total thyroidectomy performed histology showed multifocal microcarcinoma largest focus 3mm no other adverse features. patient had ablative radioactive iodine postoperatively, subsequent exit...
Abstract Background The overlying maxillary sinus frequently restrains the height of posterior bones. Purpose Evaluating effect downsizing antrostomy side‐window on stability installed implants and vertical bone gain, after employing a graftless antral membrane balloon elevation (AMBE). Materials methods study is randomized controlled clinical trial conducted 20 patients with 30 deficient alveolar ridges underwent (AMBE) being allocated into (5 mm) entry group (the test group) (10 control...
North Sinai environment is currently subjected to changes due the major agricultural development project of El-Salam canal which brings Nile water arid deserts Sinai. Therefore, intensive efforts are made record biodiversity natural microflora and diazotrophs associated plant-soil system areas around canal. Fourteen soil profiles were made, during seasons 1997-2000, representing sites area investigated (South Qantara, Rabaa-Bir El-Abd El-Ser Al-Quarir). Physico-chemical microbiological...
