conclusions in the absence of associated anomalies, the risk of incidence of adverse events does not appear to be increased significantly with isolated sua. therefore, supplementary assessment and invasive tests are not recommended in fetuses with isolated sua, unless fetal abnormalities are detected in routine evaluations. background the umbilical cord normally consists of two arteries and one...

seminal vesicles (svs) are sex accessory organs and part of male genitourinary system. they play a critical role in male fertility. diseases of the svs, usually results in infertility. diseases of the svs are extremely rare and are infrequently reported in the literature. we address the current literature of sv pathologies, symptoms, diagnosis, and treatment options. we review the clinical impo...

background: hemodialysis is a process of removing waste and excess fluid from blood when kidneys cannot function efficiently. it often involves diverting blood to the filter of the dialysis machin to be cleared of toxic substances. fouling of pores in dialysis membrane caused by adhesion of plasma protein and other toxins will reduce the efficacy of the filtre. objective: in this study, the inf...

background: gastroesophageal reflux (ger), defined as passage of gastric contents into the esophagus, and ger disease (gerd), defined as symptoms or complications of ger, are common pediatric problems. the value of commonly used diagnostic tests for ger is examined to define the most sensitive and specific test that is the least invasive as well. materials and methods: we conducted this cross s...

purpose : to compare laser interferometry (li) and ultrasound a-scan in measurement of axial length ( al ) in eyes with asteroid hyalosis methods : twenty three patients with unilateral moderate to severe asteroid hyalosis determined by b-scan ultrasonography images participated in the study. the al measurements were obtained by li and ultrasound a-scan in both asteroid hyalosis and noninvolved...

colloidal nanosilica is currently being produced by various methods which are mainly high energy intensive and/or not environmentally friendly. it is therefore essential to develop new energy-efficient and environmentally friendly technologies. this paper introduces a new ultrasound assisted route based on alkali leaching of silica fume for synthesis of colloidal silica nanoparticles. the ef...

background many multimodal analgesia techniques have been tried to provide adequate analgesia for midline incisions extending above and below the umbilicus aiming at limiting the perioperative use of morphine thus limiting side effects. ultrasound (us) guidance made the anesthesiologist reconsider old techniques for wider clinical use. the rectus sheath block (rsb) is a useful technique under-u...
