Int Arch Allergy Immunol 2021 May 5:1-14. Epub 2021 May 5.

Cancer Research Center, Semnan University of Medical Sciences, Semnan, Iran.

Coronaviruses (CoVs) were first discovered in the 1960s. Severe acute respiratory syndrome CoV-2 (SARS-CoV-2) has been identified as the cause of COVID-19, which spread throughout China and subsequently, across the world. As COVID-19 causes serious public health concerns across the world, investigating the characteristics of SARS-CoV-2 and its interaction with the host immune responses may provide a clearer picture of how the pathogen causes disease in some individuals.

Association between metabolic syndrome and resting-state functional brain connectivity.

Neurobiol Aging 2021 Apr 1;104:1-9. Epub 2021 Apr 1.

Neuroimaging Research for Veterans Center (NeRVe), Geriatric Research Education and Clinical Center (GRECC), VA Boston Healthcare System, Boston, MA, USA; Harvard Medical School, Boston, MA, USA.

The objective of this study is to examine whether metabolic syndrome (MetS), the clustering of 3 or more cardiovascular risk factors, disrupts the resting-state functional connectivity (FC) of the large-scale cortical brain networks. Resting-state functional magnetic resonance imaging data were collected from seventy-eight middle-aged and older adults living with and without MetS (27 MetS; 51 non-MetS). FC maps were derived from the time series of intrinsic activity in the large-scale brain networks by correlating the spatially averaged time series with all brain voxels using a whole-brain seed-based FC approach.

A 4-year Longitudinal Neuroimaging Study of Cognitive Control using Latent Growth Modeling: Developmental Changes and Brain-Behavior Associations.

Neuroimage 2021 May 2:118134. Epub 2021 May 2.

Department of Psychology, Virginia Tech, Blacksburg, VA 24061, U.S.A.; Fralin Biomedical Research Institute at VTC, Roanoke, VA 24016, U.S.A.

Despite theoretical models suggesting developmental changes in neural substrates of cognitive control in adolescence, empirical research has rarely examined intraindividual changes in cognitive control-related brain activation using multi-wave multivariate longitudinal data. We used longitudinal repeated measures of brain activation and behavioral performance during the multi-source interference task (MSIT) from 167 adolescents (53% male) who were assessed annually over four years from ages 13 to 17 years. We applied latent growth modeling to delineate the pattern of brain activation changes over time and to examine longitudinal associations between brain activation and behavioral performance.

J Cachexia Sarcopenia Muscle 2021 May 5. Epub 2021 May 5.

Department of Orthopedics, Xiangya Hospital, Central South University, Changsha, Hunan, China.

Sarcopenia is a progressive and widespread skeletal muscle disease that is related to an increased possibility of adverse consequences such as falls, fractures, physical disabilities and death, and its risk increases with age. With the deepening of the understanding of sarcopenia, the disease has become a major clinical disease of the elderly and a key challenge of healthy ageing. However, the exact molecular mechanism of this disease is still unclear, and the selection of treatment strategies and the evaluation of its effect are not the same. Read More

Hum Brain Mapp 2021 May 5. Epub 2021 May 5.

Cognitive Science, Department of Digital Humanities, Faculty of Arts, University of Helsinki, Helsinki, Finland.

Confidence in our retrieved memories, that is, retrospective confidence, is a metamemory process we perform daily. There is an abundance of applied research focusing on the metamemory judgments and very diverse studies including a wide range of clinical populations. However, the neural correlates that support its functioning are not well defined impeding the implementation of noninvasive neuromodulatory clinical interventions. Read More

Perfusion image guided mechanical thrombectomy combined with tirofiban successfully revascularize systemic lupus erythematosus related acute large vessel occlusion: A case report.

Medicine (Baltimore) 2021 May;100(18):e25779

Department of Neurological Surgery, the Second Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou, Zhejiang Province, China.

Associations of language-based bedtime routines with early cognitive skills and academic achievement: A follow-up from kindergarten to middle school.

Br J Dev Psychol 2021 May 5. Epub 2021 May 5.

Sorbonne Université, GRC 24 Handicap Moteur Cognitif et Réadaptation (HaMCre), Paris, France.

Objective: This study aimed to investigate the extent to which language-based bedtime routines (LBR) reported by parents before kindergarten were associated with early cognitive skills at kindergarten and subsequent academic achievement in typically developing children.
