#1
Hamid Dadkhahi, Benjamin M Marlin
In this paper, we present a new approach to learning cascaded classifiers for use in computing environments that involve networks of heterogeneous and resource-constrained, low-power embedded compute and sensing nodes. We present a generalization of the classical linear detection cascade to the case of tree-structured cascades where different branches of the tree execute on different physical compute nodes in the network. Different nodes have access to different features, as well as access to potentially different computation and energy resources...

BACKGROUND: Candesartan is one of the standard antihypertensive drug belonging to AT1R angiotensin receptor blockers (ARBs) group. Beneficial effects of this drug in the treatment of hypertension are well recognized. In this study we tested a hypothesis that candesartan could alleviate age-related memory decline. METHODS: Aged and young rats have been treated with candesartan (0.1 mg kg-1) for 21 days and then underwent a battery of behavioral tests: for assessment of long-term memory (Passive avoidance test - PA), recognition memory (Object recognition test - OR), locomotor functions (Open field - OF) and anxiety behavior (Elevated plus maze - EPM)...

Although Parkinson's disease (PD) is well known with its motor deficits, the patients often suffer from cognitive dysfunction. Apelin, as the endogenous ligand of the APJ receptor, is found in several brain regions such as substantia nigra and mesolimbic pathway. However, the role of apelin in cognition and cognitive disorders has not been fully clarified. In this study the effects of apelin-13 were investigated on cognitive disorders in rat Parkinsonism experimental model. 6-hydroxydopamine (6-OHDA) was administrated into the substantia nigra...

Previous studies have shown that spike-timing-dependent plasticity (STDP) can be used in spiking neural networks (SNN) to extract visual features of low or intermediate complexity in an unsupervised manner. These studies, however, used relatively shallow architectures, and only one layer was trainable. Another line of research has demonstrated - using rate-based neural networks trained with back-propagation - that having many layers increases the recognition robustness, an approach known as deep learning. We thus designed a deep SNN, comprising several convolutional (trainable with STDP) and pooling layers...

PURPOSE: Whether intermittent fasting (IF) treatment after stroke can prevent its long-term detrimental effects remains unknown. Here, we investigate the effects of postoperative IF on cognitive deficits and its underlying mechanisms in a permanent two-vessel occlusion (2VO) vascular dementia rat model. METHODS: Rats were subjected to either IF or ad libitum feeding 1 week after 2VO surgery. The cognition of rats was assessed using the novel object recognition (NOR) task and Morris water maze (MWM) 8 weeks after surgery...

In Alzheimer's disease, there are numerous amyloid plaques, neurofibrillary tangles, and neuronal loss in several brain areas. Oxidative stress is involved in the mechanisms of Aβ-peptide induced neurotoxicity by the generation of free radical oxidative stress that may lead to neurodegeneration. Tabernaemontana divaricata has various medical properties in Thai folklore medicine including prevent forgetfulness or improve memory. The present study aimed to investigate the effects of T. divaricata root extract (TDE) on Aβ25-35 peptides induced neuronal loss and oxidative stress in mice...

Forty years ago David Navon tried to tackle a central problem in psychology concerning the time course of perceptual processing: Do we first see the details (local level) followed by the overall outlay (global level) or is it rather the other way around? He did this by developing a now classical paradigm involving the presentation of compound stimuli; large letters composed of smaller letters. Despite the usefulness of this paradigm it remains uncertain whether effects found with compound stimuli relate directly to visual object recognition...

BACKGROUND: Due to high IgE recognition frequency and high allergenic activity, Der p 5 and Der p 21 are clinically important house dust mite (HDM) allergens. The objective of this study was to characterise the immunodominant IgE epitopes of Der p 5 and Der p 21 responsible for their high allergenic activity. METHODS: A panel of 12 overlapping peptides spanning the Der p 5 and Der p 21 sequence were synthesized to search for sequential IgE epitopes by direct testing for allergic patients ' IgE reactivity...

Hearing and cognition are commonly involved in both normal and pathological aging. Current clinical interest lies in whether peripheral hearing loss promotes cognitive decline. In our previous publication, the authors have shown a causal relationship between hearing and cognitive impairments in C57BL/6 mice. Here we extended the follow-up to 12 months to determine the long-term effects of hearing loss on cognition and to observe hippocampal p-tau and lipofuscin. One month old male mice were randomly allocated into two groups, the control (n = 12) and noise-induced hearing loss (NIHL) (n = 12)...

AIMS: Metabolic disease increases risk of Alzheimer's disease and cognitive dysfunction. Chronic high fat diet (HFD) feeding leads to cognitive impairment and neuroinflammation. This study demarcated pathological events in brain as a result of short-term to chronic HFD feeding. Efficacy of Xenin-25[Lys(13)PAL] was assessed in chronic HFD-fed mice. METHODS: C57BL/6 mice were fed HFD or normal diet for 18 days, 34 days, 10 and 21 weeks. Cognition was assessed using novel object recognition and Morris water maze...

Adverse events (AEs) of epidermal growth factor inhibitors (EGFRi) influence well-being with a risk to dose modifications (DMs). Hereby, clinical benefit of treatment might be affected. This retrospective cohort study was set up to gain insight into the suitability and added value of a patient-reported outcome measurement tool (PROM), together with a stepwise intervention management plan for EGFRi-related AEs in daily practice. The primary objective was to gain insight into total treatment duration and DMs, and the secondary objective to gain insight into patient-reported symptoms and well-being as well as healthcare professional-reported AEs...

Context • Increasing numbers of people worldwide live with a long-term health condition (LTC). Finding new ways to support people diagnosed with LTCs is important, both to improve their health-related quality of life and to manage the demands on health services that their conditions present. This effort includes a recognition of the importance of interventions to promote self-care. A growing number of systematic reviews of mindfulness meditation-based interventions (MMIs) for people with LTCs have been published but are diverse in scope and quality...

Recent findings suggest that soluble forms of amyloid-β (sAß) peptide contribute to synaptic and cognitive dysfunctions in early stages of Alzheimer's disease (AD). On the other hand, neuroinflammation and cyclooxygenase-2 (COX-2) enzyme have gained increased interest as key factors involved early in AD, although the signaling pathways and pathophysiologic mechanisms underlying a link between sAß-induced neurotoxicity and inflammation are still unclear. Here, we investigated the effects of selective COX-2 enzyme inhibition on neuropathological alterations induced by sAβ administration in rats...

Systemic inflammation is emerging as a significant driver of cognitive decline in the aged and vulnerable brain. In sepsis survivors animals low-grade brain inflammation occurs, suggesting that sepsis is able to induce in microglia a primed-like state. The purpose of this study is to analyze the role of sepsis-induced brain inflammation in the progression of the physiological process of brain aging. Wistar rats 2month-old were subjected to sepsis and 60 and 90days after were submitted to the new object recognition test and brain was removed to the determination of cytokines, myeloperoxidase (MPO) activity, amyloid-beta peptide (Aβ) and immunohistochemistry markers of microglial activation...
