Mice haploinsufficient for Map2k7, a gene involved in neurodevelopment and risk for schizophrenia, show impaired attention, a vigilance decrement deficit and unstable cognitive processing in an attentional task: impact of minocycline [PDF]

open access: yes, 2016
Rationale: Members of the c-Jun N-terminal kinase (JNK) family of mitogen-activated protein (MAP) kinases, and the upstream kinase MKK7, have all been strongly linked with synaptic plasticity and with the development of the neocortex.

Comparative analysis of choice reaction times with randomly variable foreperiods in normal individuals and schizophrenic patients

open access: yesNational Journal of Physiology, Pharmacy and Pharmacology, 2017
Background: Reaction time (RT) is an index of brain’s biological efficiency. RT can indicate sensorimotor variability with varying foreperiods (FPs) and can indicate mental dysfunction like schizophrenia.

Reaction time on fencing and karate high level athletes [PDF]

open access: yes, 2008
The great speed of the actions in combat sports makes very difficult to react quickJy without mistakes. If the fighter had longer time to react, their reaction would be more accurate.

Efficient path sampling on multiple reaction channels

open access: yes, 2007
Due to the time scale problem, rare events are not accessible by straight forward molecular dynamics. The presence of multiple reaction channels complicates the problem even further.

Learning to search. The importance of eye movements in the decrease of response times during a visual choice reaction time task [PDF]

open access: yes, 2016
Reaction times are often used as an indicator of the efficiency of the processes in thecentral nervous system. While extensive research has been conducted on the possibleresponse time correlates, the role of eye movements in visual tasks is yet unclear ...

Outcomes of Live Virus Vaccination in Patients With Vascular Anomalies Being Treated With Sirolimus

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Live vaccination in patients with vascular anomalies (VA) receiving sirolimus remains controversial due to immunosuppressive effects and theoretical risks. Procedure This single‐center retrospective study included patients with VA less than 4 years old at the start of sirolimus therapy who were incompletely vaccinated.

Pulmonary Dysfunction Is Associated With Sleep Study Abnormalities in Children With Sickle Cell Disease: A Multicenter Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Pulmonary dysfunction and sleep abnormalities are common in children with sickle cell disease (SCD) and are associated with worse clinical outcomes. Whether spirometry abnormalities are associated with polysomnography (PSG) findings remains unclear.
