The transsphenoidal approach presents unique challenges in young, with scanty literature. This study compares the outcome of pituitary tumors among young in our center between endoscopic(EES) and microscopic(MTS) transsphenoidal surgery, with a meta-analysis. Patients within 20 years were studied for their surgical approach to a favorable outcome of endocrine remission (ER) (functioning) or Gross/Near-Total resection (nonfunctioning), besides the need for retreatment. Relevant studies were pooled and analyzed according to PRISMA guidelines. Out of 64 young patients with pituitary tumors, 48 underwent transsphenoidal surgery using MTS(33) or EES(15). Of these, 21, 14, 5, and 8 had Cushing's, somatotropinomas, prolactinomas, and non-secreting tumors, respectively. Mean symptom duration was 28months, with weight gain(50 %) and visual complaints(29 %) most prevalent. Hypogonadism(21 %) was the most frequent endocrinopathy. The mean tumor volume was 3.8 cm . Over mean follow-up of 4.4years, favorable outcompy and associated with symptom duration and tumor volume. The existing evidence of the potential applications and benefits of stem cell transplantation (SCT) in people with epilepsy and also its adverse effects in humans were systematically reviewed. MEDLINE (accessed from PubMed), Google Scholar, and Scopus from inception to August 17, 2020 were systematically reviewed for related published manuscripts. The following key words (in the title) were used "stem cell" AND "epilepsy" OR "seizure". Articles written in English that were human studies on stem cell transplantation in people with epilepsy were all included. We could identify six related articles. Because of their different methodologies, performing a meta-analysis was not feasible; they included 38 adults and 81 pediatric patients together. Five studies were single-arm human studies; there were no serious adverse events in any of the studies. While stem cell transplantation seems like a promising therapeutic option for patients with drug-resistant epilepsy, data on its application is scarce and of low quality. For now, clinical stem cell-based interventions are not justified. Perhaps, in the future, there will be a rigorous and intensely scrutinized clinical trial protocol with informed consent that could provide enough scientific merit and could meet the required ethical standards.

We aimed to investigate the relationship between intracranial arterial dolichoectasia (IADE) and intracranial atherosclerosis (ICAS). Patients with acute ischemic stroke were screened via the Nanjing Stroke Registry Program. Patients were diagnosed with IADE (diameter, height of bifurcation, and laterality of basilar artery) based on magnetic resonance imaging (MRI)/magnetic resonance angiography (MRA) results. Intracranial atherosclerosis was defined as a ≥50 % diameter reduction in internal carotid artery, middle cerebral artery, posterior cerebral artery, or anterior cerebral artery on MRA, computed tomography angiography, or digital subtraction angiography. We also evaluated the presence and degree of white matter changes and lacuna infarctions on MRI. Of the 469 enrolled patients, 61 (13 %) had IADE. Patients with IADE were older (64.1 ± 9.9 vs. 59.6 ± 11.4 years, P = 0.004) and had a higher prevalence of hypertension (78.7 % vs. 61.0 %, P = 0.008) than patients without IADE. Patients with ICAS wered with advanced age, hypertension, multi-lacuna, and white matter changes but was not associated with ICAS. IADE was associated with advanced age, hypertension, multi-lacuna, and white matter changes but was not associated with ICAS. CT angiography (CTA) is not necessarily performed for all acute ischemic strokes due to variations in national guidelines across different regions. It follows that in the absence of CTA, missed identification of large vessel occlusion (LVO) potentially leads to opportunity lost for endovascular thrombectomy. Although the accuracy of CTA is well validated in chronic arterial stenosis, it has not been adequately investigated in acute ischemic stroke. We aimed to investigate the accuracy of CTA compared with digital subtraction angiography (DSA) in detecting LVO in acute ischemic stroke. This was a retrospective study of acute ischemic strokes with large vessel occlusion which underwent endovascular thrombectomy. We included patients who had a CTA prior to DSA and did not receive intravenous thrombolysis. Images were reviewed by 2 blinded assessors. Positive predictive value (PPV), and negative predictive value (NPV) of CTA were calculated against DSA. Seventy-seven patients were included. The median age was 67 (IQR 57-78) and 46 (59.7 %) were male. Median NIHSS was 18 (IQR 12-22). There were 284 arterial segments categorized into 215 anterior arterial segments in 54 patients and 69 posterior arterial segments in 23 patients. The median time between CTA and DSA was 126 min (IQR 91-153 min). https://www.selleckchem.com/products/paeoniflorin.html CTA showed PPV of 91.1 % and NPV of 95.1 % compared with DSA. We showed that CTA was reasonably accurate in identifying large vessel occlusion in acute ischemic stroke. We propose that current regional guidelines should include CTA for all acute ischemic strokes.

It was synthesied by ionic gelation method and characterized by dynamic light scattering (DLS), fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and atomic absorption spectrophotometry (AAS). The developed CS-Si NF exhibited slow release of Si and promoted gowth and yield in maize crop. Seeds primed with different concentrations of CS-Si NF (0.04-0.12%, w/v) exhibited up to 3.7 fold increased seedling vigour index (SVI) as compared with SiO2. Its foliar spray significantly induced antioxidant-defence enzymes' activities and equilibrated cellular redox homeostasis by balancing O2-1 and H2O2 content in leaf as compared with SiO2. Application of nanofertilizer (0.01-0.16%, w/v) stirred total chlorophyll content (21.
