Lithium cobalt oxide nanobatteries offer exciting prospects in the field of nonvolatile memories and neuromorphic circuits. However, the precise underlying resistive switching (RS) mechanism remains a matter of debate in two-terminal cells. Herein, intriguing results, obtained by secondary ion mass spectroscopy (SIMS) 3D imaging, clearly demonstrate that the RS mechanism corresponds to lithium migration toward the outside of the Lix CoO2 layer. These observations are very well correlated with the observed insulator-to-metal transition of the oxide...

Srona Sengupta, Robert F Siliciano
Antiretroviral therapy can effectively block HIV-1 replication and prevent or reverse immunodeficiency in HIV-1-infected individuals. However, viral replication resumes within weeks of treatment interruption. The major barrier to a cure is a small pool of resting memory CD4+ T cells that harbor latent HIV-1 proviruses. This latent reservoir is now the focus of an intense international research effort. We describe how the reservoir is established, challenges involved in eliminating it, and pharmacologic and immunologic strategies for targeting this reservoir...

This prospective study tested whether sexual activity and emotional closeness during partnered sexual activity relate to cognitive decline (episodic memory performance) in older adulthood. In total, 6016 adults aged 50 and over (2672 men, 3344 women; M age = 66.0 ± 8.8 years) completed an episodic memory task and self-report questions related to health, sexual activity, and emotional closeness. Two years later, participants again completed the episodic memory task. After controlling for demographic and health-related lifestyle factors, more frequent sexual activity and greater emotional closeness during partnered sexual activity were associated with better memory performance...

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...

Coffee's long-term effect on cognitive function remains unclear with studies suggesting both benefits and adverse effects. We used Mendelian randomization to investigate the causal relationship between habitual coffee consumption and cognitive function in mid- to later life. This included up to 415,530 participants and 300,760 coffee drinkers from 10 meta-analysed European ancestry cohorts. In each cohort, composite cognitive scores that capture global cognition and memory were computed using available tests...

Monitoring the environment for the occurrence of prospective memory (PM) targets is a resource-demanding process that produces cost to ongoing activities. The current study investigated younger and older adults' ability to monitor strategically, which involves the heightening and relaxation of monitoring when it is contextually appropriate thereby affording conservation of limited-capacity attentional resources. Participants performed a lexical-decision task in which words or nonwords were presented in upper or lower locations of the screen...

Dementia is one of the increasing problems of modern societies. The immediate cure is not a possible solution, at least at the moment, but science has found a number of new ways to retard and under specific conditions to halt its development. A potential, and constantly evolving scientific field is the use of Computerized Cognitive Rehabilitation (CCR) and Virtual Environments (Vr.E). According to the existing literature, subjecting patients to various neuro-rehabilitative conditions within 3D virtual environments, allows them to obtain significant therapeutic benefits in which both transferability and durations over time are observed, in relation to the training period of the intervention...

BACKGROUND: Continued care in patients with encephalitis and prolonged status epilepticus (SE) is controversial. Limited data is available on the functional and cognitive outcomes. METHODS: In a prospective cohort study from 2007 to 2016, patients with acute encephalitis and SE were reviewed. Long-term outcomes including motor disability (modified Rankin Scale, mRS), daily living skills (activities of daily living, ADL), cognitive ability (modified Telephone Interview for Cognitive Status, TICS-M) and epilepsy sequelae, were evaluated in those survivors at 12-month follow-up...

OBJECTIVES: To determine the relationship between glycemic status and cognitive performance in men living with (MLWH) and without HIV infection. DESIGN: A prospective HIV/AIDS cohort study in four U.S. cities between 1999 and 2016. METHODS: Glycemic status was categorized as normal glucose (NG), impaired fasting glucose (IFG), controlled diabetes mellitus (DM) and uncontrolled DM at each semi-annual visit. Cognitive performance was evaluated using nine neuropsychological tests which measure attention, constructional ability, verbal learning, executive functioning, memory, and psychomotor speed...

OBJECTIVE: We examined whether greater depressive symptoms were associated with domain-specific cognitive performance, change in cognition, and MRI markers of brain atrophy and subclinical cerebrovascular disease in a diverse sample of older adults from the Northern Manhattan Study. METHODS: Data were analyzed from the Northern Manhattan Study, a prospective cohort study of mostly Caribbean Hispanic, stroke-free, older adults. A total of 1,111 participants had baseline measures of depressive symptoms, measured as the Center of Epidemiological Studies-Depression Scale, MRI markers, and cognitive function...

BACKGROUND: Since last two decades minimally invasive techniques have revolutionized surgical field. In 2003 Pomel first described laparoscopic pelvic exenteration, since then very few reports have described minimally invasive approaches for total pelvic exenteration. METHODS: We report the 10 cases of locally advanced rectal adenocarcinoma which were operated between the periods from March 1, 2017 to November 11, 2017 at the Tata Memorial Hospital, Mumbai. All male patients had lower rectal cancer with prostate involvement on magnetic resonance imaging (MRI)...

The neurodegenerative disorder Alzheimer's disease is characterised by the formation of β-amyloid plaques and neurofibrillary tangles in the brain parenchyma, which cause synapse and neuronal loss. This leads to clinical symptoms, such as progressive memory deficits. Clinically, these pathological changes can be detected in the cerebrospinal fluid and with brain imaging, although reliable blood tests for plaque and tangle pathologies remain to be developed. Plaques and tangles often co-exist with other brain pathologies, including aggregates of transactive response DNA-binding protein 43 and Lewy bodies, but the extent to which these contribute to the severity of Alzheimer's disease is currently unknown...

Increasingly, persons entering the criminal justice system are reporting substance-related concerns. It is therefore essential that interventions appropriately target the needs of substance-using offenders to ensure the rate of reoffending can be reduced. In this context, there is now a substantial literature demonstrating specific neurocognitive deficits among substance-using and offender populations, including, but not limited to, problems with executive function, rational decision making, consequential thinking and prospective memory...

OBJECTIVE: The objective of this study is to determine the impact of intraventricular hemorrhage (IVH) on the cognitive prognosis of subarachnoid hemorrhage (SAH) due to ruptured cerebral aneurysm, independent of the presence of intraparenchymal hemorrhage, hydrocephalus or vasospasm. PATIENT AND METHODS: A Retrospective review of a prospectively collected database of patients with aneurysmal SAH from July 2009 to November 2016 was performed. Patients were included if they had a saccular aneurysm with a Hunt-Hess grade (HHG) 1-3...

OBJECTIVE: Cognitive impairment (CI) has been described in 3-80% of Systemic lupus erythematosus (SLE) patients but only short-term studies evaluated its over-time changes, suggesting that CI is usually a stable finding. We aimed at evaluating the changes of SLE-related CI in a 10-years prospective single center cohort study. METHODS: We evaluated 43 patients (M/F 5/38; mean age = 45.7±10.1 years; mean disease duration = 230.8±74.3 months) at baseline (T0) and after 10 years (T1)...
