Precise conversion electron intensities of low energy gamma transitions for efficiency calibration of electron detectors.

Precise energies and relative intensities of gamma transitions and conversion electrons in the electron capture decay of Gd have been determined independently with our well-tested and optimized gamma and electron spectrometers - a large-volume (60 cc) HPGe detector and a mini-orange electron transporter paired to a Si(Li) detector, respectively. The experimental internal conversion coefficients of the gamma transitions in Eu have been determined using Normalized Peak to Gamma method and compared with the theoretical values adopted by Nuclear Data Sheets to assign multipolarities of all the transitions. The precise internal conversion electron intensities of the low energy transitions can be used as standards for calibration purposes of electron detectors and spectrometers.

Non-invasive technique to detect diabetic retinopathy based on Electrooculography signal using machine learning classifiers.

Single-channel Electrooculogram (EOG) is proposed for detecting diabetic retinopathy. The Corneal-retinal potential of the eyes plays a vital role in the acquisition of Electrooculography. Diabetes is the most prevalent disease and for one out of three people with diabetes above 40 years, diabetic retinopathy occurs.

Non-invasive thyroid detection based on electroglottogram signal using machine learning classifiers.

Thyroid is a butterfly shaped gland located in the neck region. Hormones are secreted by the thyroid gland that is responsible for various functions that maintain metabolism of the body. The variance in secretion of the hormones causes disorders such as Hyperthyroidism or Hypothyroidism.

Spontaneous psoas hematoma in a case of acute myocardial infarction following streptokinase infusion.

Introduction: Cardiovascular disorders are the major cause of mortality and morbidity globally as well as in India. In India, where resources are limited and majority of patients pay out of their own pocket, thrombolysis is still done for majority of STEMI cases.

Case Scenario: A 48-year-old male patient, nonhypertensive and nondiabetic, came to the ER with history of retrosternal chest pain suggestive of angina at rest.

Precision electron-gamma spectroscopic measurements in the decay of 177Lu.

Complete precision electron and gamma spectroscopy measurements were undertaken for the 6.647 day decay of (177)Lu. Precision measurements of the K, L, and M internal conversion coefficients (ICCs) were made using a high transmission Mini Orange Electron Spectrometer coupled to a Si(Li) detector.

Concurrent diagnosis of rheumatic mitral stenosis & aortoarteritis: a rare combination.

A 21-year-old lady was initially diagnosed with rheumatic mitral stenosis and then 18 months later with asymptomatic aortoarteritis. She was treated with percutaneous interventions for both problems. This is a very rare combination of conditions, which has previously been reported in a few autopsy specimens.

Giant single left coronary artery with right ventricular fistula diagnosed in early childhood.

We present an unusual case of an 18-month-old boy, who presented with dyspnea and recurrent respiratory tract infections. Echocardiography and subsequent angiography were suggestive of a fistula from a coronary artery to the right ventricle. Finally, only on table could the actual diagnosis of a single left coronary artery with right ventricular fistula be made.

Aortopulmonary window in adults: diagnosis and treatment of late-presenting patients.

Objectives: Aortopulmonary window is an uncommon condition, particularly so in adulthood because it is usually fatal in infancy or childhood if untreated. Very few cases of those who have survived to adulthood and been operated on successfully have been described. Our study aimed to provide clinical, investigative, surgical, and outcome details of such patients.

Mixed supra- and infradiaphragmatic totally anomalous pulmonary venous connection in an adolescent.

An unusual type of mixed totally anomalous pulmonary venous drainage in an 11-year-old boy was diagnosed on angiography. The left-side veins drained via a vertical vein into the portal venous system, while the right-side veins drained high into the superior vena cava. Surgical correction of this abnormality was successfully performed.

Imaging features of aorto-right atrial tunnel: a report of two cases.

Aorto-right atrial tunnel is a rare congenital anomaly with very few cases described in the literature. It has been classified into anterior and posterior types and we present two operated cases, one of each type. The radiologic, echocardiographic, and angiographic features of the condition are highlighted.

Clinical presentation and investigation findings in cardiac myxomas: new insights from the developing world.

Background: Cardiac myxomas are an uncommon condition and most of the available information on their clinical features comes from smaller series of patients from developed countries. Our aim was to quantify and correlate the clinical and investigation findings in cardiac myxomas in a developing country and compare them with existing data.

Methods: A retrospective study of case notes, electrocardiograms, and x-rays of 171 patients treated for cardiac myxoma from February 1992 to October 2006 at a large charitable institution in South India was conducted.

Electron-gamma spectroscopic measurements in 131 Cs.

The decay of 131 Ba to levels of 131 Cs has been studied using an HPGe detector for gamma-ray and a mini-orange electron spectrometer for conversion electron measurements. Our experiment identifies 76 gamma transitions in this decay, including 15 new gamma rays and 6 new K-conversion electron lines. The results also include M2 multipolarity assignment for the 269 keV transition, E2 assignment to two newly observed transitions, M1 + E2 for the 406 and 417 keV transitions and M3 for the 533.

Ruptured sinus of valsalva: unexpected finding in a patient diagnosed with ventricular septal defect with aortic regurgitation.

Ruptured sinus of Valsalva aneurysm is an uncommon condition which has a good prognosis if surgically corrected. However, sometimes making the diagnosis on echocardiography and even cardiac catheterization can be difficult. We describe a case which was diagnosed as ventricular septal defect with aortic regurgitation but, on the table, was found to be a ruptured sinus of Valsalva aneurysm.

Giant ruptured sinus of Valsalva aneurysm: diagnosis on echocardiography.

A giant ruptured sinus of Valsalva aneurysm was diagnosed on transthoracic and subsequent transesophageal echocardiography, in a 45-year-old man who presented with gradual onset shortness of breath. Although the initial presentation was insidious, he later rapidly deteriorated. We discuss the unusual clinical course in a patient with such a large aneurysm and discuss the likely reasons.

Precision measurements in 124Te following the decay of 124Sb.

The decay of 124Sb (60 d half-life) to levels of 124Te has been studied using two HPGe detectors in singles and coincidence mode. We identify 75 transitions in this decay, including 14 gamma rays, the emission of which are being reported here for the first time. In confirming the existence of 26 well-established levels below 2900 keV excitation, we also introduce 5 other levels at 2490.
