Lavender improves sleep through olfactory perception and GABAergic neurons of the central amygdala.

Ethnopharmacological Relevance: The use of lavender as sleep aid or hypnotic agent can be traced back as early as ancient Romans and Greeks. Yet, objective experimental data on whether and how lavender enhances sleep duration or/and sleep quality remain lacking.

Aim Of The Study: We aimed to characterize the sleep-wake regulating effects of lavender in the mouse and to demonstrate the brain targets and neural circuits involved.

An α-hemoglobin-derived peptide (m)VD-hemopressin (α) promotes NREM sleep via the CB cannabinoid receptor.

Hemopressin and related peptides have shown to function as the endogenous ligands or the regulator of cannabinoid receptors. The previous studies demonstrated that the endocannabinoid system played important roles in modulating several physiological functions such as sleep, olfaction, emotion, learning and memory, and reward behaviors. Mouse VD-hemopressin (α) [(m)VD-HPα], an 11-residue peptide derived from the α1 chain of hemoglobin, was recently presumed as a selective agonist of the CB receptor.

[Diagnosis and Treatment Outcomes and Influencing Factors of Multidrug-Resistant Tuberculosis Based on Patient Pathway].

Multidrug-resistant tuberculosis (MDR-TB) has become one of the major challenges in the global tuberculosis (TB) control.Despite years of efforts on MDR-TB control,the treatment success rates in China have increased slowly,which indicates possible deficiencies in the management of prevention and control work.Therefore,it is necessary to analyze the current status of MDR-TB prevention and treatment based on the patient pathway.

Anesthesia management for cesarean section in a pregnant woman with odontogenic infection: A case report.

Background: In recent years, people have paid more attention to oral health with the development of stomatology. Due to the various physiological changes during pregnancy, such as changing hormone levels and immune functions, oral diseases have a high incidence during pregnancy, and the prevention and treatment of oral diseases have also received the attention of both dentists and obstetricians. However, the anesthetic management of pregnant patients with oral disease, especially severe maxillofacial infections, and patients who need surgical treatment or have obstetric emergencies and need to terminate their pregnancy is not clear.

Neuropeptide S Attenuates the Alarm Pheromone-Evoked Defensive and Risk Assessment Behaviors Through Activation of Cognate Receptor-Expressing Neurons in the Posterior Medial Amygdala.

Neuropeptide S (NPS) acts by activating its cognate receptor (NPSR). High level expression of NPSR in the posterior medial amygdala suggests that NPS-NPSR system should be involved in regulation of social behaviors induced by social pheromones. The present study was undertaken to investigate the effects of central administration of NPS or with NPSR antagonist on the alarm pheromone (AP)-evoked defensive and risk assessment behaviors in mice.

Early use of dexamethasone increases Nr4a1 in Kupffer cells ameliorating acute liver failure in mice in a glucocorticoid receptor-dependent manner.

Background And Objective: Acute liver failure (ALF) is a type of disease with high mortality and rapid progression with no specific treatment methods currently available. Glucocorticoids exert beneficial clinical effects on therapy for ALF. However, the mechanism of this effect remains unclear and when to use glucocorticoids in patients with ALF is difficult to determine.

Neuropeptide S Displays as a Key Neuromodulator in Olfactory Spatial Memory.

Neuropeptide S (NPS) is an endogenous peptide recently recognized to be presented in the brainstem and believed to play an important role in maintaining memory. The deletion of NPS or NPS receptor (NPSR) in mice shows a deficit in memory formation. Our recent studies have demonstrated that central administration of NPS facilitates olfactory function and ameliorates olfactory spatial memory impairment induced by muscarinic cholinergic receptor antagonist and N-methyl-D-aspartate receptor antagonist.

Data-Loss resilience video steganography using frame reference and data ensemble reconstruction.

In this paper, we propose a robust video steganographic method, which can efficiently hide confidential messages in video sequences, and ensure that these messages are perfectly reconstructed by recipient. To apply proposed scheme to video sequences, we must be faced with two nontrivial problems: (a) how to effectively minimize the total steganographic distortion for each video frame? (b) how to recover the hidden messages if some frames are lost or damaged? We tackle the first question by designing a new distortion function, which employs two continuous adjacent frames with the same scene as side-information. The second question is addressed by data sharing.

Physiological response and miRNA-mRNA interaction analysis in the head kidney of rainbow trout exposed to acute heat stress.

The rainbow trout is a cold-water fish cultured in China. Heat stress has a serious impact on the summer survival and the yield of rainbow trout. A better understanding of the regulatory response of rainbow trout to heat stress will help in determining the relationship between heat stress signaling pathways and adaption mechanisms and help contribute to breeding new high-temperature tolerant strains of rainbow trout.

Ethical considerations of cellular immunotherapy for cancer.

With the rapid development of immunology, molecular biology, and associated technologies such as next-generation sequencing, cellular immunotherapy has recently become the fourth major cancer treatment. Immunotherapies based on T cells, natural killer cells, and dendritic cells play key roles in cancer immunotherapy. However, their application in clinical practice raises several ethical issues.

Hepatitis B Virus Core Antigen Stimulates IL-6 Expression via p38, ERK and NF-κB Pathways in Hepatocytes.

Background: Hepatitis B virus (HBV) causes both acute and chronic liver injury. Viral proteins are involved in the pathological progress. Hepatitis B core antigen (HBcAg), a component of viral nucleocapsid, is not only essential for HBV lifecycle, but also exhibits strong immunogenicity.

Hepatitis B Virus Middle Protein Enhances IL-6 Production via p38 MAPK/NF-κB Pathways in an ER Stress-Dependent Manner.

During hepatitis B virus (HBV) infection, three viral envelope proteins of HBV are overexpressed in the endoplasmic reticulum (ER). The large S protein (LHBs) and truncated middle S protein (MHBst) have been documented to play roles in regulating host gene expression and contribute to hepatic disease development. As a predominant protein at the ultrastructural level in biopsy samples taken from viremic patients, the role of the middle S protein (MHBs) remains to be understood despite its high immunogenicity.

Phenolic Compounds from Clinopodium chinense (Benth.) O. Kuntze and Their Inhibitory Effects on α-Glucosidase and Vascular Endothelial Cells Injury.

Following an in vitro bioactivity-guided fractionation procedure, 14 compounds including eight flavonoids and six phenylpropanoids were isolated and identified from the AcOEt fraction of Clinopodium chinense (Benth.) O. Kuntze.

[Clinical and imaging features of premature infants with different degrees of bronchopulmonary dysplasia].

Objective: To study the clinical and imaging features of premature infants with different degrees of bronchopulmonary dysplasia (BPD).

Methods: A prospective study was performed on the clinical data of 59 premature infants (gestational age <32 weeks) with BPD. Among the 59 premature infants, 37 cases had mild BPD and the other 22 cases had moderate to severe BPD.

Security of quantum digital signatures for classical messages.

Quantum digital signatures can be used to authenticate classical messages in an information-theoretically secure way. Previously, a novel quantum digital signature for classical messages has been proposed and gave an experimental demonstration of distributing quantum digital signatures from one sender to two receivers. Some improvement versions were subsequently presented, which made it more feasible with present technology.

[Cross reactivity of mimotopes of hepatitis C virus hypervariable region 1].

The cross reactivity of mimotopes of hepatitis C virus (HCV) hypervariable region 1 (HVR1) was investigated to obtain epitopes that have high cross reactivity. Five expression vectors encoding B cell mimotopes fused with Trx were constructed, and the mimotope proteins were purified. The cross reactivity of mimotope proteins with HCV positive sera was determined by ELISA.
