In this study, we propose a deep convolution neural network for stroke magnetic resonance imaging(MRI) segmentation. The main structure of our network consists of two symmetrical deep sub-networks, in which dense blocks are embedded for extracting effective features from sparse pixels to alleviate the over-fitting problem of deep networks. We use the multi-kernel to divide the network into two sub-networks for acquiring more receptive fields, and the dropout regularization method to achieve an effective feature mapping. For the post-processing of the soft segmentation, we use image median filtering to alleviate noises and ...

Authors: Anlıaçık SÖ, Tokgöz S, Zamani AG, Yıldırım MS, İyisoy MS Abstract Background/aim: We aimed to investigate the associations between endothelial nitric oxide synthase(eNOS) gene polymorphisms [G894T (rs1799983)], intron 4 (27-bpTR) variable number tandem repeat (VNTR) and T786C (rs2070744), and ischemic stroke in the Anatolian population. Materials and methods: This case-control study included 112 patients with “stroke of undetermined etiology” and 160 controls. Real-time polymerase chain reaction (RT-PCR) analysis was used to analyze these polymorphisms. Between-group ...

In this study we used zeranol to protect ovariectomized (OVX) rats against cerebral I/R damage and our target is to identify the mechanism of its protection, in addition to investigating whether this mechanism inhibits inflammation (by preventing glial cell activation) and apoptosis.Main methodsFirst 18 ovariectomized rats were allocated into 3 groups: I/R group, zeranol+ I/R group and U0126, MEK1/2 inhibitor + zeranol+ I/R group. After 24 h reperfusion, protein expression of total extracellular signal-regulated protein kinase (t-ERK1/2), phosphorylated extracellular signal-regulated protein kinase (p-ERK1/2), Bcl-2, and...

All of the published prospective randomized controlled trials (RCTs) comparing carotid artery stenting (CAS, presumably from the transfemoral approach) with carotid endarterectomy (CEA) have made the uniform observation that “older patients” had fewer end points (death and stroke) with CEA compared with CAS. These findings have been criticized by some as not necessarily reflecting everyday clinical practice (often erroneously referred to as “real world”) because the strict inclusion and exclusion parameters nece ssary for a well-defined clinical trial may exclude patients otherwise undergoing treatm...

Authors: Ali A, Dorman Y, Abdullah T, Yasa C, Orhan Sungur M, Akinci IO, Ergin-Ozcan P Abstract BACKGROUND: Pulse pressure variation (PPV) and stroke volume variation (SVV) can predict fluid responsiveness effectively. However, high body mass index (BMI) can restrict their use due to changes in respiratory system compliance (CS), intra-abdominal pressure, and stroke volume (SV) in the prone position. Therefore, we aimed to investigate the effectiveness of mini fluid challenge in predicting fluid responsiveness in obese (BMI ≥30 kg/m2) patients in the prone position. METHODS: A total of 33 patients undergoing...
