The ups and downs of amphioxus biology: a history.

The ups and downs of amphioxus biology: a history. Int J Dev Biol. 2017;61(10-11-12):575-583 Authors: Holland ND, Holland LZ Abstract Humans (at least a select few) have long known about the cephalochordate amphioxus, first as something to eat and later as a subject for scientific study. The rate of publication on these animals has waxed and waned several times. The first big surge, in the late nineteenth century, was stimulated by Darwin's evolutionary ideas and by Kowalevsky's embryologic findings suggesting that an amphioxus-like creature might have bridged the gap between the invertebrates and the vertebrates. Interest declined sharply in the early twentieth century and remained low for the next 50 years. An important contributing factor (in addition to inhibition by two world wars and the Great Depression) was the indifference of the new evolutionary synthesis toward broad phylogenetic problems like the origin of the vertebrates. Then, during the 1960s and 1970s, interest in amphioxus resurged, driven especially by increased government support for basic science as well as opportunities presented by electron microscopy. After faltering briefly in the 1980s (electron microscopists were running out of amphioxus tissues to study), a third and still-continuing period of intensive amphioxus research began in the early 1990s, stimulated by the advent of evolutionary developmental biology (evo-devo) and genomics. The volume of studies peaked in 2008 with the...

The thing about smoking cigarettes is that the behavior is something we wanted to stigmatize, in order to decrease its frequency in people. At its height in the 1950s and 1960s, 2 out of every 5 people smoked in the U.S. It’s a huge health hazard, decreasing lifespan and increasing health problems in smokers. But smoking doesn’t just impact the person who smokes. Through decades’ worth of research findings, we now understand the smoking also affects the people around smokers, causing health problems and decreasing lifespans through secondhand smoke. Secondhand smoke, therefore, is also something people se...

Publication date: Available online 8 December 2018Source: NeuroscienceAuthor(s): Jiayi Shou, Angelica Tran, Natasha Snyder, Eric Bleem, Seonil KimAbstractDopaminergic signaling in the central nervous system regulates several aspects of animal behavior. In the dopaminergic circuits, there are two classes of neurons that can be differentiated by their expression of dopamine receptors, D1 or D2 receptors (D1Rs or D2Rs). Notably, Ca2+-permeable GluA2-lacking glutamate AMPA receptors (CP-AMPARs) are important for gating synaptic plasticity and gene expression in neurons, and their expression particularly in the striatum affects...

PitychoutisAbstractPreclinical evidence suggests that ketamine’s rapid and sustained antidepressant actions are due to the induction of synaptogenesis in the medial prefrontal cortex (mPFC) and the hippocampus (HIPP), two brain regions implicated in the pathophysiology of major depression. However, research on the neurobiological effects of ketamine has focused almost exclusively on males. Findings from our group and others indicate that female rodent...

Authors: Yu W, Zhao H, Zong X, Ji X, Han X, Wang Y, Zhang Y, Ma K, Cui N, Wang S Abstract Radix Astragali (RA) herb with warm property and significant "tonifying qi" effects is indicated for the syndrome of internal cold due to Yang deficiency. The purpose of this research was to explore effects of Radix Astragali (RA) through PPAR signaling pathway on gene expression profiles related to energy metabolism in rats with the Yang-deficiency cold (YDC) syndrome, for identifying the pathological mechanism of Yang-deficiency cold (YDC) syndrome and the effects mechanism of RA. The results indicated that RA coul...

Conclusion: Targeted interventions aimed at eliminating victimization behaviours within the school context are therefore proposed, as well as interventions to promote healthy parenting styles for the parents of schoolchildren. Moreover, school healthcare professionals should screen students involved in bullying for self-injury, and vice versa. PMID: 30519578 [PubMed - in process]

However, it is unclear whether psychological dependency on social media and social media use behavior have beneficial offline effects. We conducted an online survey of 1391 valid LGBT recruited in China and also interviewed five LGBT Weibo users to better explain some results. We found LGBT with higher levels of de...

In this study, we explored microRNAs as predictive markers of drug response to duloxetine, a serotonin-norepinephrine reuptake inhibiter, using peripheral blood samples from 3 independent clinical trials (NCT00635219; NCT0059991; NCT01140906) comparing 6-8 weeks of treatment with duloxetine to placebo treatment in patients with MDD. Plasma microRNA was extracted and sequenced using the Ion Proton Sequencer. Rank feature selection analysis was used to identify microRNAs in the top 10th percentile for their differentiating ability between patients who remitted and did not remit with duloxetine treatment. The results were the...
