Trocarless laparoscopic pyloromyotomy with conventional instruments: Our experience
Journal of Minimal Access Surgery, 2013 Background: The incidence of hypertrophic pyloric stenosis is approximately 1-3 per 1,000 live births. Hypertrophic pyloric stenosis is seen more often in males, with a male-to female ratio of 4:1.

StenUNet: Automatic Stenosis Detection from X-ray Coronary Angiography [PDF]
arXiv, 2023 Coronary angiography continues to serve as the primary method for diagnosing coronary artery disease (CAD), which is the leading global cause of mortality. The severity of CAD is quantified by the location, degree of narrowing (stenosis), and number of arteries involved.

SSASS: Semi-Supervised Approach for Stenosis Segmentation [PDF]
arXiv, 2023 Coronary artery stenosis is a critical health risk, and its precise identification in Coronary Angiography (CAG) can significantly aid medical practitioners in accurately evaluating the severity of a patient's condition. The complexity of coronary artery structures combined with the inherent noise in X-ray images poses a considerable challenge to this ...

A Recurrent CNN for Automatic Detection and Classification of Coronary Artery Plaque and Stenosis in Coronary CT Angiography [PDF]
, 2018 Various types of atherosclerotic plaque and varying grades of stenosis could lead to different management of patients with coronary artery disease. Therefore, it is crucial to detect and classify the type of coronary artery plaque, as well as to detect and determine the degree of coronary artery stenosis.

Comorbid CAD and Ventricular Hypertrophy Compromise The Perfusion of Myocardial Tissue at Subcritical Stenosis of Epicardial Coronaries [PDF]
, 2018 BACKGROUND: Most studies of CAD revascularization have been based on and reported according to angiographic criteria which don't consider the relation between the resulting effective flow distal to the stenosis and the demand of a hypertrophied myocardial tissue.

Two New Stenosis Detection Methods of Coronary Angiograms [PDF]
arXiv, 2021 Coronary angiography is the "gold standard" for diagnosing coronary artery disease (CAD). At present, the methods for detecting and evaluating coronary artery stenosis cannot satisfy the clinical needs, e.g., there is no prior study of detecting stenoses in prespecified vessel segments, which is necessary in clinical practice.

Adult idiopathic hypertrophic pyloric stenosis
Journal of the Formosan Medical Association, 2015 Idiopathic hypertrophic pyloric stenosis (IHPS) is a predominantly infantile disease. The adult type of IHPS is extremely rare but it has been well recognized since the 19th century.

Journal of Pediatric Surgery Case Reports, 2021 A case of “Recurrent Pyloric Stenosis” is presented. From the perspective of a senior pediatric surgeon, this is a new entity. Why? Perhaps it is because improvements in ultrasound technology have enabled earlier detection of pyloric hypertrophy.

A rare case of recurrent hypertrophic pyloric stenosis
Journal of Pediatric Surgery Case Reports, 2014 Hypertrophic pyloric stenosis (HPS) is perhaps the most commonly encountered gastrointestinal disease process in the pediatric surgical patient. While the etiology remains unclear, progression of the disease is well described and uniformly results in non-

Ca2+ release via IP3 receptors shapes the cytosolic Ca2+ transient for hypertrophic signalling in ventricular cardiomyocytes [PDF]
, 2019 Calcium (Ca2+) plays a central role in mediating both contractile function and hypertrophic signalling in ventricular cardiomyocytes. L-type Ca2+ channels trigger release of Ca2+ from ryanodine receptors (RyRs) for cellular contraction, while signalling downstream of Gq coupled receptors stimulates Ca2+ release via inositol 1,4,5-trisphosphate ...
