Revealing neural circuit mechanisms is critical for understanding brain functions. Significant progress in dissecting neural connections has been made using optical imaging with fluorescence labels, especially in dissecting local connections. However, acquiring and tracing brain-wide, long-distance neural circuits at the neurite level remains a substantial(More)
Our recent research demonstrates that the extracellular signal-regulated kinase (ERK) signal pathway is impaired in depressed animals, and such disruption is effectively reversed following antidepressant treatment. These results indicate that the ERK pathway may participate in the molecular mechanism of depression. To provide direct evidence for the(More)
Neural circuits are fundamental for brain functions. However, obtaining long range continuous projections of neurons in the entire brain is still challenging. Here a two-photon fluorescence micro-optical sectioning tomography (2p-fMOST) method is developed for high-throughput, high-resolution visualization of the brain circuits. Two-photon imaging(More)
BACKGROUND Wood is the end product of secondary vascular system development, which begins from the cambium. The wood formation process includes four major stages: cell expansion, secondary wall biosynthesis, lignification, and programmed cell death. Transcriptional profiling is a rapid way to screen for genes involved in these stages and their transitions,(More)
In the present study, 40 Sprague-Dawley rats were divided into forced swim stress group and controls, with 20 rats in each group (10 for behavioral tests, 10 for protein detection). The forced swim stress group received swim stress for 14 consecutive days, and the controls were stress-free. After stress, 20 rats were tested for behavioral observation using(More)
Tobacco addiction is characterized by a negative mood state upon smoking cessation and relapse after periods of abstinence. Clinical studies indicate that negative mood states lead to craving and relapse. The partial α4/α6/β2* nicotinic acetylcholine receptor (nAChR) agonists varenicline and cytisine are widely used as smoking cessation treatments.(More)
The anticonvulsant drug lamotrigine has been shown to produce strong antidepressant effects in the treatment of patients with bipolar disorder. However, to date there are few preclinical reports on its behavioral actions in animal models of depression or its underlying molecular mechanisms. The current study investigated the effects of lamotrigine in the(More)
The anticonvulsant drug lamotrigine has been shown to produce antidepressant effects in patients with bipolar disorder. To date, only a few preclinical studies have been conducted using lamotrigine treatment in the forced swim test (FST), an animal model of depression with low face validity. The underlying mechanisms by which lamotrigine works have not been(More)
Co-expression of a lesquerella fatty acid elongase and the castor fatty acid hydroxylase in camelina results in higher hydroxy fatty acid containing seeds with normal oil content and viability. Producing hydroxy fatty acids (HFA) in oilseed crops has been a long-standing goal to replace castor oil as a renewable source for numerous industrial applications.(More)
When exposed to nonlethal heat stress (i.e., heat shock preconditioning), HSP72 expression increased in the mammalian brain. HSP72 enhance the viability of neurons and decrease TUNEL-positive neurons under several kinds of stress (e.g., ischemic). Chronic psychological stress is a kind of stress that could cause hippocampal neuron apoptosis. But whether(More)
