We next develop an iterative co-design process for the systematic design of more hardware-friendly CNNs whilst considering hardware constraints, such as core sizes. A python wrapper, developed for the mapping process, is also useful for validating hardware design and studies on traffic volume and energy consumption. Finally, a new neural network dubbed HFNet is proposed using the above co-design process; it achieves a classification accuracy of 71.3% on the IMAGENET dataset (comparable to the VGG-16) but uses 11 times less cores for neuromorphic hardware with core size of 1,024 × 1,024. Selleckchem Nirogacestat We also modified the HFNet to fit onto different core sizes and report on the corresponding classification accuracies. Various aspects of the paper are patent pending.Methods Alzheimer's disease and Frontotemporal dementia are the first and third most common forms of dementia. Due to their similar clinical symptoms, they are easily misdiagnosed as each other even with sophisticated clinical guidelines. For disease-specific intervention and treatment, it is essential to develop a computer-aided system to improve the accuracy of their differential diagnosis. Recent advances in deep learning have delivered some of the best performance for medical image recognition tasks. However, its application to the differential diagnosis of AD and FTD pathology has not been explored. Approach In this study, we proposed a novel deep learning based framework to distinguish between brain images of normal aging individuals and subjects with AD and FTD. Specifically, we combined the multi-scale and multi-type MRI-base image features with Generative Adversarial Network data augmentation technique to improve the differential diagnosis accuracy. Results Each of the multi-scale, multitype, and data augmentation methods improved the ability for differential diagnosis for both AD and FTD. A 10-fold cross validation experiment performed on a large sample of 1,954 images using the proposed framework achieved a high overall accuracy of 88.28%. Conclusions The salient contributions of this study are three-fold (1) our experiments demonstrate that the combination of multiple structural features extracted at different scales with our proposed deep neural network yields superior performance than individual features; (2) we show that the use of Generative Adversarial Network for data augmentation could further improve the discriminant ability of the network regarding challenging tasks such as differentiating dementia sub-types; (3) and finally, we show that ensemble classifier strategy could make the network more robust and stable.Functional MRI (fMRI) utilizes changes in metabolic and hemodynamic signals to indirectly infer the underlying local changes in neuronal activity. To investigate the mechanisms of fMRI responses, spontaneous fluctuations, and functional connectivity in the resting-state, it is important to pursue fMRI in animal models. Animal studies commonly use dexmedetomidine sedation. It has been demonstrated that potent sensory stimuli administered under dexmedetomidine are prone to inducing seizures in Sprague-Dawley (SD) rats. Here we combined optical imaging of intrinsic signals and cerebral blood flow with neurophysiological recordings to measure responses in rat area S1FL to electrical forepaw stimulation administered at 8 Hz. We show that the increased susceptibility to seizures starts no later than 1 h and ends no sooner than 3 h after initiating a continuous administration of dexmedetomidine. By administering different combinations of anesthetic and sedative agents, we demonstrate that dexmedetomidine is the soleedetomidine are possibly due to the induction of epileptic activity. Therefore, caution should be practiced in experiments that combine the administration of potent stimuli with dexmedetomidine sedation. We propose stimulation paradigms that elicit seizure-free, well detectable neurophysiological and hemodynamic responses in rats. We further conclude that the increased susceptibility to seizures under dexmedetomidine sedation is species dependent.Acute esophageal necrosis (AEN) is a rare and often fatal pathology of unclear etiology affecting the distal two-thirds of the esophagus. Typically, elderly patients with multiple comorbidities present with signs of upper gastrointestinal (GI) hemorrhage. On endoscopy, the mucosa is black due to ischemic necrosis, resulting in the commonly used term "black esophagus." We present a rare case of a 61-year-old male presenting with shortness of breath and hematemesis diagnosed as AEN through endoscopy. This case illustrates the importance of considering AEN as part of differential diagnoses in a rising elderly population with multiple comorbidities that present with upper GI hemorrhage. Treatment should be aimed at maintaining hemodynamic stability with high-dose proton pump inhibitors.
The study aimed to review the literature on the use of ultraviolet-C (UV-C) sterilization to assess its clinical efficacy in reducing risk and transmission of nosocomial infections as well as its associated health safety or hazards.

Four main search engines were used to identify potential studies which included (1) Google Scholar, (2) ScienceDirect, (3) PubMed, and (4) Cochrane. Studies in English and published from 2010 to 2020 were considered. Studies on efficacy were limited to those in unseeded hospital environments, examining environmental disinfection, and with true experimental, randomized controlled trial, or quasi-experimental study designs. No additional criterion was used for safety studies due to the scarcity of literature. In the end, a total of 17 studies were selected. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Risk of bias assessment and manual data extraction and tabulation were done.

Twelve eligible efficacy studies were identified togesafe exposure dose, especially for 222 nm germicidal lamps. Direct evidence is needed for any targeted implementation of UV-C during Coronavirus Disease 2019 (COVID-19) pandemic.
Acute kidney injury (AKI) is a major cause of morbidity and mortality. Whether aminophylline administration can prevent or treat AKI among pediatric patients are not clear. This meta-analysis aimed to assess the efficacy and effectiveness of aminophylline for pediatric AKI.

We carried out a systematic search of six databases PubMed, EMBASE/Excerpta Medica, Scopus, Cochrane library, and Google Scholar from January 1995 up till May 2019. Summary measures of risk ratios and standard mean difference were calculated using the random effects model.

We identified seven papers containing data on aminophylline use in children with AKI. Meta-analysis of single-arm studies indicated no statistically significant difference in mean rate of serum creatinine clearance (-0.39 [-0.80-1.58],
= 0.52), mean urine output (1.99 [-1.43-5.42];
= 0.25), or mean blood urea nitrogen levels (0.83 [-1.86-3.03],
= 0.54) before and after aminophylline administration. However, among double-arm studies, aminophylline administration in the intervention arm significantly reduced the serum creatinine level as compared to control arm (mean diff = -34 [-55.
