Should the Lateral Chest Radiograph be a Routine Projection in the Diagnosis of Pneumonia in Children: A Narrative Review?
Chest x-rays (CXR) are frequently used in the diagnosis of pneumonia in pediatrics patient. The lateral projection produces more than double the effective patient dose than the frontal (anterior-posterior (AP)/ posterior-anterior (PA)) projection in CXR series, with potentially little assistance in diagnosing disease.
In the conventional XRR analysis, the X-ray reflectivity has been calculated based on the Parratt formalism, accounting for the effect of roughness by the theory of Nevot-Croce conventionally. However, the calculated results have shown often strange behaviour where interference effects would increase at a rough surface.
Recent literature has suggested that junior doctors’ knowledge of ionising radiation is inadequate. Advances in technology and availability have led to of these investigations being readily requested. Exposure is associated with adverse risks especially malignancy; therefore in accordance with the Ionising Radiation (Medical Exposures) Regulation (IR(ME)R), clinicians should be aware of radiation doses and their legal responsibility as referrers.
Preeclampsia is clinically defined by hypertension and proteinuria, with or without pathologic edema that occurs after 20 weeks’ gestation, but can also present up to 4-6 weeks post-partum. Worldwide, incidence of preeclampsia is 5-14 percent of all pregnancies, while severe preeclampsia can develop to about 25 percent of all cases of preeclampsia.
Mesoporous NiO films obtained via screen-printing deposition of a newly formulated paste containing preformed NiO-nanospheres have been employed as nanostructured photocathodes of p-type dye-sensitized solar cells (p-DSCs).
Plasmon Mediated Photocatalysis by Solar Active Ag/ZnO Nanostructures: Degradation of Organic Pollutants in Aqueous Conditions
Present article focuses on the in-situ generated Ag/ZnO nano catalyst for effluent treatment. It is observed that synthesis of the catalyst using starch as environment friendly surfactant resulted in plate like elongated Zinc Oxide nanoparticles.
The Effects of the Special K Challenge on Body Composition and Biomarkers of Metabolic Health in Healthy Adults
The Special K Challenge is a short term (14 day) partial meal replacement diet designed to reduce body mass and motivate long term reduction in body mass.
We report here on new optic and small-angle X-ray scattering (SAXS) measurements concerning the formation of the dispersions from double-stranded (ds) DNA molecules, doped with negatively charged gold nanoparticles (nano-Au). The nano-Au fixation nearby the surfaces of linear ds DNA in solution of high ionic strength (0.3 M NaCl) and subsequent phase exclusion of (ds DNA-nano-Au) complexes from solution containing poly(ethylene glycol) results in decrease in the amplitude of abnormal negative band in the circular dichroism spectra of the formed cholesteric liquid-crystalline dispersions (CLCD).
Persisting Cough as the Single Presenting Symptom of an Intrathoracic Tumor in a Nine-Month-Old Child with Adenovirus Airway Infection
We report on a nine-month-old girl who presented with persisting cough, and diminished ventilation of the left hemithorax. Viral pneumonia was suspected after Adenovirus detection by PCR, but chest X-rays showed a persistent shadowing of the left hemithorax and persistent coughing despite clinical improvement. Because of the discrepancy between clinical and radiological signs further investigations by ultrasound and CT scan were performed, which visualized an intrathroracic tumor. Histopathology confirmed diagnosis of a teratoma.
The Ni(II) Complex of 2-Hydroxy-Pyridine-N-Oxide 2-Isothionate: Synthesis, Characterization, Biological Studies, and X-ray Crystal Structures using (1) Cu Kα Data and (2) Synchrotron Data
C12H20N6NiO6S2 or NiL2(SCN)2](NH4)2.2H2O, where L is 2-hydroxy-pyridine-N-oxide, has been prepared and characterized using elemental analyses, IR, UV and visible spectrometry, magnetic moment measurements, thermal analyses and single crystal X-ray analyis. The results indicate that the complex reacts as a bidentate ligand and is bound to the metal ion via the two oxygen atoms of the ligand (HL).
Legal Medical Age Estimation in Portuguese Adult Cadavers: Evaluation of the Accuracy of Forensic Dental Invasive and Non-Invasive Methods
Age estimation of unknown human cadavers is important in setting a crime investigation, such as homicide, suicide or in mass disaster because it can guide forensic investigators to the correct identity among a large number of possible matches. More and more the courts ask for medico-legal age estimations of unknown human cadavers by forensic dentistry.
Post-mortem imaging in the form of plain X-ray films has been in use for many years as an adjunct or occasionally as a substitute for autopsy. However, in the last two decades there has been increasing interest and investigation into the use of advanced techniques such as Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) in death investigation.
The design of an electrochemical reactor for the preparation of self-supported comparatively thin (up to 10 μm) and large area (up to 50 cm2) anodic alumina membranes is described allowing growth of porous alumina at high applied potential (up to 150 V) without burning.
Fabrication of Vertical Cu2ZnSnS4 Nanowire Arrays by Two-Step Electroplating Method into Anodic Aluminum Oxide Template
Vertical Cu2ZnSnS4 (CZTS) nanowire arrays have been synthesized via two-step electroplating method into anodized aluminum oxide template. For deposition of CZTS nanowires, anodized aluminum oxide (AAO) was used as the growth mask for the growth of the nanowires. AAO templates with hole sizes of 70 nm in diameter were used in the experiments.
