ROAR-CAT: Rapid Online Assessment of Reading ability with Computerized Adaptive Testing.

The Rapid Online Assessment of Reading (ROAR) is a web-based lexical decision task that measures single-word reading abilities in children and adults without a proctor. Here we study whether item response theory (IRT) and computerized adaptive testing (CAT) can be used to create a more efficient online measure of word recognition. To construct an item bank, we first analyzed data taken from four groups of students (N = 1960) who differed in age, socioeconomic status, and language-based learning disabilities.

Correcting mitochondrial loss mitigates NOTCH1-related aortopathy in mice.

Loss-of-function mutations in NOTCH1 were previously linked to thoracic aortopathy, a condition for which non-surgical treatment options are limited. Based on clinical proteome analysis, we hypothesized that mitochondrial fusion and biogenesis in aortic smooth muscle cells (SMCs) are crucial for regulating the progression of NOTCH1-related aortopathy. Here we demonstrate that SMC-specific Notch1 knockout mice develop aortic pathology, including stiffening, dilation and focal dissection.

A phase I study of the CDK4/6 inhibitor ribociclib combined with gemcitabine in patients with advanced solid tumors.

Background: Based on preclinical data showing addition of CDK4/6 inhibitors to gemcitabine was synergistic, ribociclib was evaluated in combination with gemcitabine to determine the maximum tolerated dose (MTD) and dose limiting toxicities (DLT).

Methods: In this single arm multicohort phase I trial, we evaluated the safety and efficacy of ribociclib plus gemcitabine in patients with advanced solid tumors. Patients received gemcitabine intravenously on days 1 and 8 followed by ribociclib days 8-14, with treatment repeated every 3 weeks.

Apoptosis in polycystic ovary syndrome: Mechanisms and therapeutic implications.

Polycystic ovary syndrome (PCOS) is a common disorder that affects the female reproductive system, with an incidence of 8 % to 15 %. It is characterized by irregular menstruation, hyperandrogenemia, and polycystic abnormalities in the ovaries. Nevertheless, there is still much to learn about the molecular pathways underlying PCOS.

Effects of bright light therapy on cingulate cortex dynamic functional connectivity and neurotransmitter activity in young adults with subthreshold depression.

Background: The neurobiological mechanisms behind the antidepressant effect of bright light therapy (BLT) are unclear. We aimed to explore the dynamic functional connectivity (dFC) changes of the cingulate cortex (CC) in subthreshold depression (StD).

Methods: The StD participants (38 BLT and 39 placebo) underwent resting-state functional magnetic resonance imaging (rs-fMRI) and mood assessment before and after eight-week BLT.
