When acute myocardial infarction occurs in patients with hypertension and left ventricular hypertrophy (LVH), the incidence of sudden cardiac death increases markedly. Possible explanations include increased size of the occluded vascular bed secondary to more extensive atherosclerotic coronary vascular disease in the presence of hypertension, decreased coronary reserve secondary to LVH, and int...

OBJECTIVE A randomized controlled selective cross-over trial was performed to compare the diagnostic yield and efficacy of ExEm foam (HyFoSy) with saline medium (HyCoSy) as a contrast agent for hysterosalping-contrast sonography in subfertile patients. STUDY DESIGN 40 patients were randomized into HyCoSy with saline medium and HyFoSy with ExEm foam. Tubal patency were assessed according to pr...

INTRODUCTION This study was carried out to investigate the effect of 808nm diode laser irradiation on dentinal tubules of root canal wall. MATERIALS AND METHODS Twelve single-rooted teeth were used. After cleaning and shaping with rotary instruments by the crown down technique, the smear layer was removed by alternating irrigation with EDTA and sodium hypochlorite. The teeth were then randoml...

BACKGROUND Collateral flow to the infarct artery territory after acute myocardial infarction may be associated with improved clinical outcomes and may also impact the benefit of subsequent recanalization of an occluded infarct-related artery. METHODS AND RESULTS To understand the association between baseline collateral flow to the infarct territory on clinical outcomes and its interaction wit...

This study was designed to examine the functional properties of myocardium subjected to acute coronary occlusion but surviving the ischemic insult. Ten conscious mongrel dogs underwent mild-circumflex coronary occlusion and were treated for 6 hours with prostacyclin, 540 ng/kg/min, and ibuprofen, 110 micrograms/kg/min, or dipyridamole (7-9.7 micrograms/kg/min). At 7 days, each dog was anestheti...

OBJECTIVE To assess the frequency of systemic venous collaterals to the atria, which may cause desaturation, after stage II reconstructive surgery for hypoplastic left heart syndrome (HLHS) and to determine whether coil occlusion prevents the need for surgical ligation. DESIGN Prospective interventional study. SETTING Tertiary referral centre. PATIENTS 27 children with HLHS undergoing car...

This study was designed to examine the functional properties of myocardium subjected to acute coronary occlusion but surviving the ischemic insult. Ten conscious mongrel dogs underwent midcircumflex coronary occlusion and were treated for 6 hours with prostacyclin, 540 ng/kg/min, and ibuprofen, 110 puglkg/min, or dipyridamole (7-9.7 gg/kg/min). At 7 days, each dog was anesthetized, the chest wa...

OBJECTIVES To study the prevalence of arterial diseases in the arteries supplying the lumbar spine and their relation to other vascular diseases, as well as to chronic low back pain. METHODS Five pairs of the lumbar arteries and the middle sacral artery were evaluated from 140 postmortem aortograms, performed in connection with routine medicolegal necropsies on subjects ranging from 16 to 89 ...

BACKGROUND To examine histomorphometrically the parapapillary region in human eyes. METHODOLOGY/PRINCIPAL FINDINGS The histomorphometric study included 65 human globes (axial length:21-37 mm). On anterior-posterior histological sections, we measured the distance Bruch's membrane end (BME)-optic nerve margin ("Gamma zone"), BME-retinal pigment epithelium (RPE) ("Beta zone"), BME-beginning of n...

The rapid and accurate detection of cherry tomatoes is great significance to realizing automatic picking by robots. However, so far, are detected as only one class for picking. Fruits occluded branches or leaves pickable objects, which may cause damage the plant robot end-effector during This study proposed Feature Enhancement Network Block (FENB) based on YOLOv4-Tiny solve above problem. First...
