Boyi Hu, Chong Kim, Xiaopeng Ning, Xu Xu
Low back pain remains one of the most prevalent musculoskeletal disorders, while algorithms that able to recognize low back pain patients from healthy population using balance performance data are rarely seen. In this study, human balance and body sway performance during standing trials were utilized to recognize chronic low back pain populations using deep neural networks. To be specific, forty-four chronic LBP and healthy individuals performed static standing tasks while their spine kinematics and center of pressure were recorded...

The dominant paradigm for understanding working memory, or the combination of the perceptual, attentional, and mnemonic processes needed for thinking, subdivides short-term memory (STM) according to whether memoranda are encoded in aural-verbal or visual formats. This traditional dissociation has been supported by examples of neuropsychological patients who seem to selectively lack STM for either aural-verbal, visual, or spatial memoranda, and by experimental research using dual-task methods. Though this evidence is the foundation of assumptions of modular STM systems, the case it makes for a specialized visual STM system is surprisingly weak...

BACKGROUND: Tata Memorial Centre (TMC) is a high-volume centre for pancreatic tumour resections. We found a continually increasing referral of pancreatic tumours for re-evaluation for surgery, after an initial unsuccessful attempt at resection. AIM: To evaluate reasons of initial in-operability, the feasibility of re-operative pancreatico-duodenectomy (R-PD) and short- and long-term outcomes after R-PD. METHODS: Data was collected from a prospective database of GI and hepato-pancreato-biliary service, TMC, Mumbai from January 2008 to December 2016...

Waterpipe tobacco smoking (WTS) was previously shown to be associated with memory deficits, which were related to oxidative stress. Vitamin C (VitC) has established antioxidant properties against memory deficits associated with several diseases and conditions. In this study, the potential protective effect of VitC on memory impairment induced by WTS exposure was evaluated in a rat model. VitC was administered to animals via oral gavage (100 mg/kg/day, 6 days a week for 4 weeks). At the same period, animals were exposed to WTS for one hour/day, 6 days a week for 4 weeks...

Objective: Psychiatric symptoms, including depression and apathy, may significantly impede functional and cognitive capabilities following a cerebrovascular event. This study examined the role of apathy and depression on learning and memory performance in stroke patients. Method: Stroke patients (n = 140 [119 ischemic, 21 hemorrhagic], mean age = 60.6 [SD = 15.1]) completed the Apathy Evaluation Scale (AES), the Center for Epidemiologic Studies Depression Scale (CES-D), and the California Verbal Learning Test-Second Edition (CVLT-II)...

The leading cause of death in the juvenile population is trauma, and in particular neurotrauma. The juvenile brain response to neurotrauma is not completely understood. Endoplasmic reticulum (ER) stress has been shown to contribute to injury expansion and behavioral deficits in adult rodents and furthermore has been seen in adult postmortem human brains diagnosed with chronic traumatic encephalopathy. Whether endoplasmic reticulum stress is increased in juveniles with traumatic brain injury (TBI) is poorly delineated...

Apathy is frequently reported in individuals with Parkinson's disease (PD) and is hypothesized to be associated with frontal-striatal related cognitive functions. Available data, however, do not provide univocal results. Moreover, this relationship has been poorly investigated in PD patients with mild cognitive impairment (MCI). This study was aimed at investigating the association between severity of apathy of PD patients and their performance on neuropsychological tests investigating executive abilities. Individuals with PD (i...

Early detection of high fall risk is an essential component of fall prevention in older adults. Wearable sensors can provide valuable insight into daily-life activities; biomechanical features extracted from such inertial data have been shown to be of added value for the assessment of fall risk. Body-worn sensors such as accelerometers can provide valuable insight into fall risk. Currently, biomechanical features derived from accelerometer data are used for the assessment of fall risk. Here, we studied whether deep learning methods from machine learning are suited to automatically derive features from raw accelerometer data that assess fall risk...

Fish in schooling formations navigate complex flow fields replete with mechanical energy in the vortex wakes of their companions. Their schooling behavior has been associated with evolutionary advantages including energy savings, yet the underlying physical mechanisms remain unknown. We show that fish can improve their sustained propulsive efficiency by placing themselves in appropriate locations in the wake of other swimmers and intercepting judiciously their shed vortices. This swimming strategy leads to collective energy savings and is revealed through a combination of high-fidelity flow simulations with a deep reinforcement learning (RL) algorithm...

Treatments for metabolic diseases, such as diet and therapeutics, often provide short-term therapy for metabolic stressors, but relapse is common. Repeated bouts of exposure to, and relief from, metabolic stimuli results in a phenomenon we call "metabolic cycling." Recent human and rodent data suggest metabolic cycling promotes an exaggerated response and ultimately worsened metabolic health. This is particularly evident with cycling of body weight and hypertension. The innate and adaptive immune systems have a profound impact on development of metabolic disease, and current data suggest that immunologic memory may partially explain this association, especially in the context of metabolic cycling...

Due to the near-field coupling effect, non-close-packed nanoparticle (NP) assemblies with tunable interparticle distance (d) attract great attention and show huge potential applications in various functional devices, e.g., organic nano-floating-gate memory (NFGM) devices. Unfortunately, the fabrication of device-scale non-close-packed 2D NPs material still remains a challenge, limiting its practical applications. Here, a facile yet robust "rapid liquid-liquid interface assembly" strategy is reported to generate a non-close-packed AuNP superlattice monolayer (SM) on a centimeter scale for high-performance pentacene-based NFGM...

The aim of this study was to evaluate the accuracy of neuropsychological assessment in predicting conversion from subjective cognitive decline (SCD) and mild cognitive impairment (MCI) to Alzheimer's disease (AD) and the effect of personality traits and cognitive reserve in progression from SCD to MCI. As part of a longitudinal, clinical-neuropsychological-genetic survey on SCD and MCI, 284 patients referred to our hospital between 1990 and 2017 were included. All patients underwent clinical-extensive neuropsychological evaluation and Apolipoprotein E genotyping; personality traits were assessed in a subgroup...

Information from preceding trials of cognitive tasks can bias performance in the current trial, a phenomenon referred to as interference. Subjects performing visual working memory tasks exhibit interference in their responses: the recalled target location is biased in the direction of the target presented on the previous trial. We present modeling work that develops a probabilistic inference model of this history-dependent bias, and links our probabilistic model to computations of a recurrent network wherein short-term facilitation accounts for the observed bias...

It has been suggested that the concreteness effect in short-term memory (STM) is a consequence of concrete words having more distinctive and richer semantic representations. The generation and storage of visual codes in STM could also play a crucial role on the effect because concrete words are more imaginable than abstract words. If this were the case, the introduction of a visual interference task would be expected to disrupt recall of concrete words. A Dynamic Visual Noise (DVN) display, which has been proven to eliminate the concreteness effect on long-term memory (LTM), was presented along encoding of concrete and abstract words in a STM serial recall task...

Sleep deprivation (SD) influences physiological processes such as cognitive function. The balance of oxidant and antioxidant markers, neurotrophic factors and magnesium are affected by sleep deprivation but there is no difference between pre and post training sleep deprivation. This study was designed to investigate memory retrieval and biochemical factors such as oxidant and antioxidant enzyme, brain-derived neurotrophic factor (BDNF) and magnesium levels in the hippocampus following pre and post-training sleep deprivation...

Stimulation of the immune system during pregnancy, known as maternal immune activation (MIA), can cause long-lasting neurobiological and behavioral changes in the offspring. This phenomenon has been implicated in the etiology of developmental psychiatric disorders, such as autism and schizophrenia. Much of this evidence is predicated on animal models using bacterial agents such as LPS and/or viral mimics such as Poly I:C, both of which act through toll-like receptors. However, fewer studies have examined the role of direct activation of maternal T-cells during pregnancy using microbial agents...

In a rapidly changing environment, we often know when to do something before we have to do it. This preparation in the temporal domain is based on a 'perception' of elapsed time and short-term memory of previous stimulation in a similar context. These functions could be perturbed in Parkinson's disease. Therefore, we investigated their role in eye movement preparation in sporadic Parkinson's disease and in a very infrequent variant affecting the Parkin gene. We used a simple oculomotor task where subjects had to orient to a visual target and movement latency was measured...

EphB2 is involved in enhancing synaptic transmission and gene expression. To explore the roles of EphB2 in memory formation and enhancement, we used a photoactivatable EphB2 (optoEphB2) to activate EphB2 forward signaling in pyramidal neurons in lateral amygdala (LA). Photoactivation of optoEphB2 during fear conditioning, but not minutes afterward, enhanced long-term, but not short-term, auditory fear conditioning. Photoactivation of optoEphB2 during fear conditioning led to activation of the cAMP/Ca2+ responsive element binding (CREB) protein...

OBJECTIVE: Patients with amnestic Mild Cognitive Impairment (aMCI), usually considered an early stage of Alzheimer's disease, have deficits not only in retrospective memory (RM), that is, recalling of past events, words or people, but also on prospective memory (PM), the cognitive ability of remembering to execute delayed intentions in the future. This study investigated whether patients with aMCI refer more PM complaints as compared with RM complaints, and whether this might depend upon short-term vs long-term items or time-based vs event-based tasks...
