FAM83A-AS1 predicts severe development of non-small cell lung cancer and adverse postoperative prognosis of thoracotomy.

Background: Thoracotomy is a common treatment for non-small cell lung cancer (NSCLC). However, the significant trauma from this procedure can limit patients' postoperative prognosis. Therefore, it's crucial to find an easily detected indicator that can predict the prognosis of NSCLC patients undergoing thoracotomy.

NRG1-ErbB4 signaling in the cerebrospinal fluid-contacting nucleus regulates thermal pain in mice.

The cerebrospinal fluid-contacting nucleus(CSF-contacting nucleus) is a pair of unique nuclei in the brain parenchyma which has long been demonstrated to play an important role in pain signal processing. However, the mechanisms by which the CSF-contacting nucleus intervenes in pain is unclear. The NRG1-ErbB4 signaling plays an important role in the nervous system and has been shown to be involved in the regulation of pain.

[mA RNA methylation is a potential biological target for neuropathic pain].

N6-methyladenosine (mA) is the most common type of RNA modification in eukaryotes, which affects intracellular RNA metabolism and controls gene expression of related pathophysiological processes through dynamic reversible regulation of methyltransferases, demethylases and mA-binding proteins. In recent years, the involvement of mA methylation in the study of neuropathic pain has become a hot topic, some new understandings have been emerging, and mA methylation has become a potential biological target for the treatment of neuropathic pain. Therefore, this article reviews the role and regulation of mA methylation in neuropathic pain, in order to provide new enlightenment for the drug development and treatment of neuropathic pain.

A longitudinal evaluation of oxidative stress - mitochondrial dysfunction - ferroptosis genes in anthracycline-induced cardiotoxicity.

Background: Antineoplastic medications, including doxorubicin, idarubicin, and epirubicin, have been found to adversely affect the heart due to oxidative stress - mitochondrial dysfunction - ferroptosis (ORMFs), which act as contributing attributes to anthracycline-induced cardiotoxicity. To better understand this phenomenon, the time-resolved measurements of ORMFS genes were analyzed in this study.

Methods: The effect of three anthracycline drugs on ORMFs genes was studied using a human 3D cardiac microtissue cell model.

Improved EfficientNet for corn disease identification.

Introduction: Corn is one of the world's essential crops, and the presence of corn diseases significantly affects both the yield and quality of corn. Accurate identification of corn diseases in real time is crucial to increasing crop yield and improving farmers' income. However, in real-world environments, the complexity of the background, irregularity of the disease region, large intraclass variation, and small interclass variation make it difficult for most convolutional neural network models to achieve disease recognition under such conditions.

In the first part of the experiment, rats with CIP were divided into the immunofluorescence group and the coimmunoprecipitation (Co-IP) group (n = 6).

Activation of P2X4 receptors in midbrain cerebrospinal fluid-contacting nucleus leads to mechanical hyperalgesia in chronic constriction injury rats.

Neuropathic pain is a refractory pain state, and its mechanism is still not clear. Previous studies have shown that the purine receptor P2X4R expressed on hyperactive microglia in the spinal cord is essential for the occurrence and development of neuropathic pain. The cerebrospinal fluid-contacting nucleus (CSF-contacting nucleus) in the midbrain has been found to play an important role in the descending inhibition system of modulation.

Cerebrospinal fluid contacting nucleus and its 5-HT: A new insight into the regulation mechanism of general intravenous anesthesia.
