In animal studies, both seizures and interictal spikes induce synaptic potentiation. Recent evidence suggests that electroencephalogram slow wave activity during sleep reflects synaptic potentiation during wake, and that its homeostatic decrease during the night is associated with synaptic renormalization and its beneficial effects. Here we asked whether epileptic activity induces plastic changes that can be revealed by high-density electroencephalography recordings during sleep in 15 patients with focal epilepsy and 15 control subjects...

Background: Evidence has shown neurocognitive problems often exist among human immunodeficiency virus (HIV)-infected children. There are limited data for children in Nigeria. Methods: This was a cross-sectional study of 100 school-aged perinatally HIV-infected children seen in the paediatric HIV clinic and age/sex-matched controls from the general paediatric clinic. Neuro-cognitive functioning was assessed using the Raven's progressive matrices (RPM) that has been adapted for the Nigerian population...

OBJECTIVES: According to the technical intelligence hypothesis, humans are superior to all other animal species in understanding and using tools. However, the vast majority of comparative studies between humans and chimpanzees, both proficient tool users, have not controlled for the effects of age, prior knowledge, past experience, rearing conditions, or differences in experimental procedures. We tested whether humans are superior to chimpanzees in selecting better tools, using them more dexteriously, achieving higher performance and gaining access to more resource as predicted under the technical intelligence hypothesis...

We developed a 3D vision-based semi-autonomous control interface for assistive robotic manipulators. It was implemented based on one of the most popular commercially available assistive robotic manipulator combined with a low-cost depth-sensing camera mounted on the robot base. To perform a manipulation task with the 3D vision-based semi-autonomous control interface, a user starts operating with a manual control method available to him/her. When detecting objects within a set range, the control interface automatically stops the robot, and provides the user with possible manipulation options through audible text output, based on the detected object characteristics...

BACKGROUND AND OBJECTIVE: A high percentage of medical errors, committed because of physician's lack of experience, huge volume of data to be analyzed, and inaccessibility to medical records of previous patients, can be reduced using computer-aided techniques. Therefore, designing more efficient medical decision-support systems (MDSSs) to assist physicians in decision-making is crucially important. Through combining the properties of fuzzy logic and neural networks, fuzzy cognitive maps (FCMs) are among the latest, most efficient, and strongest artificial intelligence techniques for modeling complex systems...

Wearable devices, such as smart glasses and watches, allow for continuous recording of everyday life in a real world over an extended period of time or lifelong. This possibility helps better understand the cognitive behavior of humans in real life as well as build human-aware intelligent agents for practical purposes. However, modeling the human cognitive activity from wearable-sensor data stream is challenging because learning new information often results in loss of previously acquired information, causing a problem known as catastrophic forgetting...

In 2010 in an article in these pages I argued that declassified documents implicated Central Intelligence Agency physicians in the conduct of unethical research on enhanced interrogation using detainee subjects. The focus, then as now, is upon physicians at the Office of Medical Services. The 2010 article highlighted the heavily redacted DRAFT OMS GUIDELINES ON MEDICAL AND PSYCHOLOGICAL SUPPORT TO DETAINEE INTERROGATIONS. This commentary focuses upon the recently declassified final version of that document revealing further culpable evidence of unethical human subject research...

Sensors can be installed on various body parts to provide information for computer diagnosis to identify the current body state. However, as human posture is subject to gravity, the direction of the force on each limb differs. For example, the directions of gravitational force on legs and trunk differ. In addition, each person's height and structure of limbs differs, hence, the acceleration and rotation resulted from such differences on force and length of the limbs of a person in motion would be different, and be presented by cases of different postures...

Enabling touch-sensing capability would help appliances understand interaction behaviors with their surroundings. Many recent studies are focusing on the development of electronic skin because of its necessity in various application domains, namely autonomous artificial intelligence (e.g., robots), biomedical instrumentation, and replacement prosthetic devices. An essential task of the electronic skin system is to locally process the tactile data and send structured information either to mimic human skin or to respond to the application demands...

Critical building blocks for the response to HIV were made until 2012 despite a series of political, social and financial challenges. A rapid increase of HIV service coverage was observed from 2012 to 2015 through collaborative efforts of government and non-governmental organisations (NGOs). Government facilities, in particular, demonstrated their capacity to expand services for antiretroviral therapy (ART), prevention of mother-to-child transmission (PMTCT) of HIV, tuberculosis and HIV co-infection and methadone-maintenance therapy (MMT)...

The arrival of modern brain imaging technologies has provided new opportunities for examining the biological essence of human intelligence as well as the relationship between brain size and cognition. Thanks to these advances, we can now state that the relationship between brain size and intelligence has never been well understood. This view is supported by findings showing that cognition is correlated more with brain tissues than sheer brain size. The complexity of cellular and molecular organization of neural connections actually determines the computational capacity of the brain...

Understanding the effect of exogenous substances on human skin is critical for toxicology assessment. To address this, numerous artificial models of the topmost layer of human skin, so-called reconstructed human epidermis (RhE), have been created in an attempt to produce a clear analogue for testing. Unfortunately, current testing modalities still rely on endpoint assays and are not capable of monitoring time-resolved changes in barrier function without using numerous redundant samples. In this work, a novel, time-resolved approach is realized by monitoring the transepithelial electrical resistance (TEER) of MatTek EpiDerm® reconstructed human epidermis model, utilizing an automated protocol with the Intelligent Mobile Lab for in vitro diagnostics (IMOLA-IVD)...

Neurotransmitter release in chemical synapses is fundamental to diverse brain functions like motor action, learning, cognition, emotion, perception and consciousness. Moreover, improper functioning or abnormal release of neurotransmitter is associated with numerous neurological disorders like epilepsy, sclerosis, schizophrenia, Alzheimer's disease and Parkinson's disease. We have utilized hysteresis engineering in a back gated MoS2 field effect transistor (FETs) in order to mimic such neurotransmitter release dynamics in chemical synapses...

Today, there is considerable interest in personal healthcare. The pervasiveness of technology allows to precisely track human behavior; however, when dealing with the development of an intelligent assistant exploiting data acquired through such technologies, a critical issue has to be taken into account; namely, that of supporting the user in the event of any transgression with respect to the optimal behavior. In this paper we present a reasoning framework based on Simple Temporal Problems that can be applied to a general class of problems,, which we called "cake&carrot problems", to support reasoning in presence of human transgression...
