Effect of ultrasound on bond strength and penetration of resin and ionomeric cements used for fiberglass post cementation
The objective of this study was to evaluate the bond strength of fiberglass posts (Reforpost ®) cemented with RelyX U200 and RelyX Luting 2, with (A) and without (WA) ultrasonic activation in the root canal of bovine teeth. The penetration of the cements into dentine tubules was also assessed. Methods: Forty bovine incisors were selected and endodontically treated, and then divided into 4 groups (n = 10). Fiberglass posts were cemented with RelyX U200 and RelyX Luting 2
and activated with an ITSMO ultrasound insert in 2 groups; the other two groups received no ultrasonic activation. After 24
hours of cementation, the roots were sectioned into slices of approximately 1 mm each. Confocal microscopy and push-out
test were performed, and all specimens were subjected to 200× magnification optical microscopy for mode of failure evaluation. Statistical analysis was done with three-way ANOVA, followed by the Fisher’s test (α = 0.05)
Arduino Use in Education Systems to Monitor the Noise in Schools Classrooms in Qatar
Many students suffer from the sound of air conditioners and others suffer from light intensity in classroom. The air conditioners and light intensity affect the efficiency and quality of education. Urduino is used a lot in industrial areas because there is a lot of noise pollution. Additionally, it can be used in high traffic regions as well as to monitor noise in different parts of the city. It can also be used in education systems to monitor the noise in classrooms. The purpose of this study was to monitor the noise in classrooms by Arduino Nano that interfaced with a Sound Sensor.
A study was conducted to determine the ambient sound and light intensity of a convenience sample at school during September, October and November 2021. Six classrooms’ samples corresponding to hourly fractions of the average sample broken down into the following periods: from 10:00 am to 2:50 pm. Sound levels were measured to assess acoustic conditions. Light levels were measured to assess light conditions. Each classroom from 1 to 6 was tested the ambient sound intensity and light using an Arduino.
Noise varies with time and place. The sound level varies between 27.5 dB and 65 dB with the average sound level in the classrooms was 43.53 dB greater than recommended sound level limit of 35 dB. The light intensity varies between 62.50 lux and 208.5 lux. The average light levels around the recommended 300 lux. Everyone emphasized the quality of using the device to measure the noise level in the classroom. The use of the device leads to monitor the noise of the air conditioner or replacing it.
The device has the potential to significantly change the noise pollution monitoring system at school. Researchers recommend all students and authorities the importance of the Arduino.
To Evaluate the Efficacy of Ultrasound Guided Distraction Osteogenesis by Evaluating Qualitative Estimation of Bone Fill at Regeneration site and Management of Severe Mandibular Hypoplasia Secondary to Obstructive Sleep Apnoea: A Case Report
Distraction Osteogenesis (DO) is an established method for correction of developmental anomaly of the facial skeleton. The early
beginning of urgent surgical corrections are allowed in smaller age as even small children suffering from bilateral severe mandibular
deficiency who are often associated with breathing and swallowing disorder caused by glossoptosis.
Managing Heterotopic Pregnancy with Ectopic Egg Location from a Hypoplastic Horn: A Case Report

Review of the Diagnostic Value of Ultrasound Imaging in Giant Cell Arteritis
Giant cell arteritis (GCA) requires prompt diagnosis as clinical indicators of GCA are non-specific. Temporal artery biopsy (TAB) can be inconclusive and difficult to arrange timely. MR imaging is accurate for showing vessel thickening. However, the availability of MRI remains an issue in many radiology departments.
Ultrasound Criteria for Expecting Mode of Delivery after Induction of Labour in Primigravida with Postdates
Intrapartum transabdominal US of the positions of the fetal head recorded during labor could be useful indicator for expecting persistent Occipito Posterior position and labor induction failure.
Ultrasound as a New Imaging Tool to Assess Pathological Change of Joints in Preclinical Mouse Models of Osteoarthritis
Murine osteoarthritis (OA) models are important for exploring OA pathology and treatment in the pre-clinical study. Longitudinal in vivo imaging modalities, including X-ray, computed tomography, and magnetic resonance imaging, are commonly used diagnostic tools in OA clinic, while end-point histomorphometry analysis is the major outcome measurement in the pre-clinical study because clinical imaging modalities have limited resolution for small animals.
B-Lines on Chest Ultrasound Predicts Elevated Left Ventricular Diastolic Pressures
Background: Echocardiography and lung ultrasound are important tests for assessing left the ventricular function in patients presented to the emergency department with acute pulmonary edema. Chest ultrasound is becoming an important tool in diagnosing acute pulmonary edema.
Aim: To investigate the relationship between the B profile on ultrasound chest and Spectral tissue Doppler echocardiography (E/e’ratio) in patients presented with the suspicion of acute pulmonary edema.
Methods: This paper reports a prospective observational study of 61 consecutive patients, which was presented with symptoms and signs of pulmonary edema and B - profile detected by echocardiography with a 5 MHz curvilinear probe. Critical care physicians trained in ultrasound examination performed echocardiography and chest ultrasounds.
Osteo-Articular Complications in a Pediatric Sickle Cell Disease Population - Imaging Value
Sickle cell disease (SCD) is the most frequent of a group of conditions known as haemoglobinopathies. The disease is an autosomal recessive genetic disorder, characterized by abnormal haemoglobin (Hemoglobin S) that under certain conditions polymerizes resulting in microvascular occlusions. This pictorial review illustrates the osteo-articular manifestations associated with sickle-cell disease encountered in children in our institution with at least one Haematology appointment in 2013/2014. Osteo-articular manifestations with imaging findings were reported in 28 out of 97 patients. The most frequent complications and those that required hospital care were painful vaso-occlusive crisis and femoral head osteomyelitis.
Case Report of Severe Preeclampsia and Associated Postpartum Complications
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.
Fibromatosis Colli, a Rare Cause of Neck Mass in Infants: A Case Report
Fibromatosis colli is a benign fibrous mass developed from the sternocleidomastoid muscle. The exact etiologies are unknown. It seems that it is due to birth trauma. Ultrasound is the diagnostic tool of choice. The treatment is based on physiotherapy.
Parenteral Nutrition in the Newborn: Associated Disorders and Nutritional Aspects
Severe prematurity at birth is an indicator of additional attention for the multidisciplinary team, since the newborn in this condition did not have the opportunity to develop organic systems under ideal conditions (intrauterine). Several factors may induce premature birth, malformation of organs or metabolic disruptions, however, additional attention has been given to inborn errors of metabolism (IEM) and deficiency/excess of key nutrients.
Ascites Secondary to Compression of the Caudal Vena Cava by Liver Abscesses in a Cow
Ascites due to thrombosis of the caudal vena cava is relatively seldom in cattle. To our knowledge, there have been no reports of ascites secondary to compression of the caudal vena cava by liver abscesses. This case report describes the findings in a 3.7-year-old Brown Swiss cow with this disease.
Spontaneous Coronary Artery Dissection: Efficient Clinical Outcome through Percutaneous Coronary Intervention
Spontaneous coronary artery dissection (SCAD) is a rare myocardial ischemic disease that threatens patients’ life. Various risk factors are associated with SCAD, such as smoking, severe hypertension and psychological reasons. Considering the formation of dissection, SCAD can be divided into intimal tear type or intraluminal hemorrhage type.
