In this task, you are given a abstract of article and corresponding title of an article. Your task is to generate label "yes" if title is right for article, otherwise generate "no".

Input: Consider Input: Abstract: Infection of Sulfolobus islandicus REY15A with mixtures of different Sulfolobus viruses, including STSV2, did not induce spacer acquisition by the host CRISPR immune system. However, coinfection with the tailed fusiform viruses SMV1 and STSV2 generated hyperactive spacer acquisition in both CRISPR loci, exclusively from STSV2, with the resultant loss of STSV2 but not SMV1. SMV1 was shown to activate adaptation while itself being resistant to CRISPR-mediated adaptation and DNA interference. Exceptionally, a single clone S-1 isolated from an SMV1 + STSV2-infected culture, that carried STSV2-specific spacers and had lost STSV2 but not SMV1, acquired spacers from SMV1. This effect was also reproducible on reinfecting wild-type host cells with a variant SMV1 isolated from the S-1 culture. The SMV1 variant lacked a virion protein ORF114 that was shown to bind DNA. This study also provided evidence for: (i) limits on the maximum sizes of CRISPR loci; (ii) spacer uptake strongly retarding growth of infected cultures; (iii) protospacer selection being essentially random and non-directional, and (iv) the reversible uptake of spacers from STSV2 and SMV1. A hypothesis is presented to explain the interactive conflicts between SMV1 and the host CRISPR immune system.. Title: Inter-viral conflicts that exploit host CRISPR immune systems of Sulfolobus.

Input: Consider Input: Abstract: Optogenetic technologies employ light to control biological processes within targeted cells in vivo with high temporal precision. Here, we show that application of molecular trafficking principles can expand the optogenetic repertoire along several long-sought dimensions. Subcellular and transcellular trafficking strategies now permit (1) optical regulation at the far-red/infrared border and extension of optogenetic control across the entire visible spectrum, (2) increased potency of optical inhibition without increased light power requirement (nanoampere-scale chloride-mediated photocurrents that maintain the light sensitivity and reversible, step-like kinetic stability of earlier tools), and (3) generalizable strategies for targeting cells based not only on genetic identity, but also on morphology and tissue topology, to allow versatile targeting when promoters are not known or in genetically intractable organisms. Together, these results illustrate use of cell-biological principles to enable expansion of the versatile fast optogenetic technologies suitable for intact-systems biology and behavior..

Input: Consider Input: Abstract: Background: Reduced brain insulin signaling and low CSF-to-plasma insulin ratios have been observed in patients with Alzheimer disease (AD). Furthermore, intracerebroventricular or IV insulin administration improve memory, alter evoked potentials, and modulate neurotransmitters, possibly by augmenting low brain levels. After intranasal administration, insulin-like peptides follow extracellular pathways to the brain within 15 minutes. Objective: We tested the hypothesis that daily intranasal insulin treatment would facilitate cognition in patients with early AD or its prodrome, amnestic mild cognitive impairment (MCI). The proportion of verbal information retained after a delay period was the planned primary outcome measure. Secondary outcome measures included attention, caregiver rating of functional status, and plasma levels of insulin, glucose, -amyloid, and cortisol. Methods: Twenty-five participants were randomly assigned to receive either placebo (n = 12) or 20 IU BID intranasal insulin treatment (n = 13) using an electronic atomizer, and 24 participants completed the study. Participants, caregivers, and all clinical evaluators were blinded to treatment assignment. Cognitive measures and blood were obtained at baseline and after 21 days of treatment. Results: Fasting plasma glucose and insulin were unchanged with treatment. The insulin-treated group retained more verbal information after a delay compared with the placebo-assigned group ( p = 0.0374). Insulin-treated subjects also showed improved attention ( p = 0.0108) and functional status ( p = 0.0410). Insulin treatment raised fasting plasma concentrations of the short form of the -amyloid peptide (A40; p = 0.0471) without affecting the longer isoform (A42), resulting in an increased A40/42 ratio ( p = 0.0207). Conclusions: The results of this pilot study support further investigation of the benefits of intranasal insulin for patients with Alzheimer disease, and suggest that intranasal peptide administration may be a novel approach to the treatment of neurodegenerative disorders..
