There is an interest in developing materials with bioactive potential that could block exposed dentinal tubules. This study compared the effects of eggshell and seashell nanoparticles individually or combined with ND:YAG laser on dentinal tubules occlusion and remineralization. Fifty radicular dentin discs were prepared from freshly extracted human premolars.

Cancer continues to be the most dangerous disease around the world; it causes electrolyte imbalance as well as metabolic changes. There is a complicated relationship between electrolyte disorder and cancer. Cancer patients commonly pass with abnormalities in serum electrolyte levels such as hypokalemia, hyperkalemia, hyponatremia, and hypercalcemia.

Cardiovascular complications in ST-segment-elevation myocardial infarction survivors remain substantial despite advances in the management of STEMI. We aimed to determine effect of AH on the area at risk (AAR), final infarct size (FIS), and salvage index (SI) in STEMI patients using cardiac magnetic resonance (CMR). 43 successfully reperfused STEMI patients were recruited.

Introduction: To assess if the apparent diffusion coefficient (ADC) value of magnetic resonance imaging (MRI) can discriminate between the cell type, histological grade and improve staging of urinary bladder cancer (BC).

Material And Methods: 102 patients with urinary bladder masses underwent MRI using a 1.5 T machine.

Article Synopsis
  • This study presents a unique case of an isolated renal hydatid cyst in a 54-year-old woman, initially misidentified as a possible tumor due to her symptoms and imaging results.
  • The patient underwent radical nephrectomy after the imaging indicated a cystic lesion with a double-layer wall, which was later found to be the germinative membrane of the hydatid cyst during histopathological examination.
  • The findings suggest that isolated renal hydatid cysts can easily be mistaken for renal tumors, emphasizing the need to include them in the differential diagnosis of renal cystic conditions.

Analysis of trace elements in mammalian hair has the potential to reveal retrospective information about an individual's nutritional status and exposure. As trace elements are incorporated into the hair during the growth process, longitudinal segments of the hair may reflect the body burden during growth. Using LIBS technique, Na, K, Ca, Mg, Si, Fe, Pb and Zn were detected in a single strand of horse hair.

Release of heavy metals into waterways without treatment can cause a significant threat to the environment. In this paper, we present a method of improving the removal of heavy metals by using Eichhornia crassipes roots (ECR) supported on a polymethyl methacrylate (PMMA) thin film. The functional groups of the synthesized PMMA sample were identified by Fourier transform infrared spectroscopy.

Objective: To monitor femoral artery blood flow by Doppler velocimetry in women treated for postpartum hemorrhage (PPH) with and without the adjunction of the External Aortic Compression Device (EACD), and to assess the possible adverse effects of the device.

Methods: Blood flow velocity in the femoral artery, as well as skin color and sensory or motor changes in the lower limbs, were assessed in 120 women with primary PHH of any cause, quasi randomized to either treatment group. Pulse rate, oxygen saturation, respiratory rate, urinary output, and gastrointestinal symptoms were checked in the study group.

Background: A prediction formula for mean pulmonary artery pressure (MPAP) using standard lung function measurement has been recently validated to screen for pulmonary hypertension (PH) in idiopathic pulmonary fibrosis (IPF) patients.

Objective: To test the usefulness of this formula as a new non invasive screening tool for PH in IPF patients. Also, to study its correlation with patients' clinical data, pulmonary function tests, arterial blood gases (ABGs) and other commonly used screening methods for PH including electrocardiogram (ECG), chest X ray (CXR), trans-thoracic echocardiography (TTE) and computerized tomography pulmonary angiography (CTPA).

Objective: To present our experience with repairing penile fracture, based on clinical and magnetic resonance imaging (MRI) findings.

Patients And Methods: Between December 2002 and October 2004, 14 men (19-64 years old) presented to our centre with a penile fracture. Two patients had urethral bleeding.

The purpose of this paper is to provide the reader with comparative information about two new commercial echelle spectrometers equipped with intensified CCD (ICCD) detectors for laser-induced breakdown spectroscopy analysis. We carried out a performance comparison between two commercial ICCD/echelle spectrometers [ESA 3000 (LLA Instruments GmbH, Berlin-Adlershof, Germany) and a Mechelle 7500 (Multichannel Instruments, Stockholm, Sweden)] for the determination of the concentrations of Be, Mg, Si, Mn, Fe, and Cu in the same Al alloy samples adopting the same experimental conditions. The results show that both systems, despite their differences in terms of resolution, have similar performance in terms of sensitivity and precision of measurements for these elements in an Al alloy matrix at least for the range of wavelength 280-400 nm studied in this work.
