Background: One of the most common causes of infertility in women is ovulatory dysfunction (PCOS) and the choice of treatment is clomiphene citrate. One of the mechanism of dichotomy between the rate of ovulation and pregnancy is anti estrogenic effects of clomiphene citrate on endometrium. According to its long half life, the anti estrogenic effects probably exacerbate in consecutive cycles. W...

Background The endometrial echopattern on the day of human chorionic gonadotropin (HCG) administration and its relationship to the outcome of pregnancy after assisted reproductive treatment (ART) cycles was analyzed, prospectively. MaterialsAndMethods This study conducted between 2013 to 2014. The endometrial pattern was evaluated prospectively on the day of administration of HCG in 280 ART cyc...

The exact relationship between ultrasonograms and histological findings of the pancreas was investigated in 24 postmortem materials consisting of II cases of normal pancreas, 9 of pancreatic tumor and 4 of chronic pancreatitis, Normal pancreas showed a smooth contour and a homogeneous echo pattern with uniform echo intensity which was 10 dB higher than that of the normal liver. Pancreatic tumor...

International guidelines suggest ultrasound surveillance for hepatocellular carcinoma (HCC) early diagnosis in liver cirrhosis (LC) patients, but 40% of nodules <2 cm escape detection. We investigated the existence of an ultrasound pattern indicating a higher risk of developing HCC in patients under surveillance. 359 patients with LC (Child-Pugh A-B8) underwent ultrasound screening (median foll...

gestational choriocarcinoma usually occurs following an intrauterine pregnancy. we report a case of metastatic choriocarcinoma to the left kidney and lungs with long term intermittent amenorrhea and vaginal bleeding after a normal vaginal delivery. a 43 year old rural woman presented with three years intermittent amenorrhea and vaginal bleeding following normal vaginal delivery. she also compla...

To clarify the determinants of pulmonary valve (PV) motion in pulmonary hypertension, we examined the correlations among PV echo patterns, the pulmonary artery (PA) flow curve just above the PA orifice and the pulmonary artery-right ventricle (PA-RV) pressure gradient. By constricting the PA, we could produce a variety of PV echo patterns, including midsystolic semiclosure in open-chest dogs. T...

Recurrent neural networks capable of sequential pattern generation could facilitate new types of applications like music generation. Here, we explore the capability of echo state networks for parameterized pattern generation and present a new approach utilizing regression in the model space. The goal of the learning is a system that can generate patterns for previously unseen parameterizations....
