This study explored the possible role of orexin one receptors (Orx1R) in the basolateral amygdala (BLA) on the modulation of nitroglycerin (NTG)-induced migraine-like symptoms. In addition, pain-induced subsequent alteration in learning and memory competence was evaluated in the adult male Wistar rats.

To investigate whether small conductance Ca activated channels; Trigeminal ganglion; Trigeminal neuralgia. (SK3) exists in normal rats' trigeminal ganglions (TG) and its effect on their pain thresholds. In total, 110 healthy adult male Sprague-Dawley (SD) rats were involved in this study. Ten rats were dissected to collect their liver tissues, TG and DRG. The rest of the rats were randomly assigned to either the experimental group or the control group. The animal model of trigeminal neuralgia (TN) was established by infraorbital nerve ligation. The expression of SK3 channels in their livers, TG and dorsal root ganglions (DRG) were detected. And different doses of SK3 channel activator and inhibitor were administered to the rats in both groups 15 days after the operation; meanwhile, their pain thresholds were also measured. The expression of SK3 channel was found in TG. In the experimental group, the pain threshold was significantly decreased and there was a decreased level of SK3 than that in the control group at 15 days after operation. The administration of SK3 channel agonist (CyPPA) could significantly improve the pain threshold, while, the pain threshold decreased after administration of SK3 channel antagonist (Apamin). The SK3 channel may play a pivotal role in the pathogenesis of trigeminal neuralgia, and it may be one of the potential targets for the treatment of trigeminal neuralgia.

Sick building symptoms (SBS) are defined as non-specific symptoms related to indoor exposures, including mucosal symptoms in eye, nose, throat, and skin, and general symptoms as headache and tiredness. Indoor microbial composition is associated with SBS symptoms, but the impact of microbial functional genes and potential metabolic products has not been characterized. We conducted a shotgun microbial metagenomic sequencing for vacuum dust collected in urban and rural schools in Shanxi province, China. SBS symptoms in students were surveyed, and microbial taxa and functional pathways related to the symptoms were identified using a multi-level linear regression model. SBS symptoms were common in students, and the prevalence of ocular and throat symptoms, headache, and tiredness was higher in urban than in rural areas (p < 0.05). A significant higher microbial α-diversity was found in rural areas than in urban areas (Chao1, p = 0.001; ACE, p = 0.002). Also, significant variation in microbial taxonomic and functional composition (β-diversity) was observed between urban and rural areas (p < 0.005). Five potential risk Actinobacteria species were associated with SBS symptoms (p < 0.01); students in the classrooms with a higher abundance of an unclassified Geodermatophilaceae, Geodermatophilus, Fridmanniella luteola, Microlunatus phosphovorus and Mycetocola reported more nasal and throat symptoms and tiredness. Students with a higher abundance of an unclassified flavobacteriaceae reported fewer throat symptoms and tiredness. The abundance of microbial metabolic pathways related to the synthesis of B vitamins (biotin and folate), gamma-aminobutyric acid (GABA), short-chain fatty acids (SCFAs), and peptidoglycan and were protectively (negatively) associated with SBS symptoms (FDR < 0.05). The result is consistent with human microbiota studies, which reported that these microbial products are extensively involved in immunological processes and anti-inflammatory effects. This is the first study to report the functional potential of the indoor microbiome and the occurrence of SBS, providing new insights into the potential etiologic mechanisms in chronic inflammatory diseases.

To compare the outcomes for patients with chronic plantar fasciitis after extracorporeal shockwave therapy (ESWT) or autologous blood injection (ABI).

Pericardial tamponade is a complication of percutaneous coronary intervention (PCI) with extremely high mortality. The rupture of coronary artery causes hypotension and shock, eventually resulting in death due to pericardial tamponade. Because of the complex operation in revascularization of chronic total occlusion (CTO-PCI) lesion, the incidence of pericardial tamponade increases. Usually, we use coronary angiogram to identify the rupture of coronary artery after PCI by the contrast agent. We presented a 67-year-old woman with pericardial tamponade after CTO revascularization. She had chest pain and out of breath for nearly two years. The coronary angiogram showed three branch lesion and CTO lesion of the right coronary artery (RCA). After revascularization of the RCA CTO lesion, the pericardial effusion and low blood pressure occurred, but we didn't find the leak of contrast agents during the final angiography. Then the patient was transferred to cardiac surgery department for emergency thoracotomy. They found the hematoma on the surface of the RCA and finally discharged without any symptoms. Our case approved: (I) there was still the possibility of coronary artery rupture even the coronary angiogram showed no contrast agent leakage from the coronary artery after PCI; (II) the combined use of IVUS and coronary angiogram may improve the accuracy and safety of CTO revascularization procedure.

Macrophages play a key role in inflammation, infection, cancer, and repairing damaged tissues. Thus, modulating macrophages with engineered nanomaterials is an important therapeutic strategy for healing chronic inflammatory injuries. However, designing and manufacturing therapeutic nanomaterials remains challenging. Therefore, in this study, apoptotic-cell-inspired deformable phosphatidylserine (PS)- containing nanoliposomes (D-PSLs) with a Young's modulus (E) of approximately 0.5 kPa were constructed via a facile and scalable method. Compared with similar-sized conventional PSLs with an E of approximately 80 kPa, the D-PSLs had a lower uptake efficacy, a much longer binding time to the cell surface, and induced enhanced anti-inflammatory and pro-healing effects via the synergistic effects of their mechanical stimulus and PS-receptor mediation after recognition by macrophages. In particular, chronic wound healing in diabetic rats showed that D-PSLs can efficiently promote M2-like macrophage polarization, increase the expression of the vascular endothelial marker CD31 and accelerate wound closure. Our findings suggest that soft D-PSLs represent a promising biomimetic nano-therapeutic approach for macrophage immunotherapy for chronic inflammatory injury, and that the mechanical stimulus of nanomaterials significantly affects the receptor-mediated biological responses, which will inspire the design of engineered nanomaterials for biomedical applications. STATEMENT OF SIGNIFICANCE: : Macrophages play a significant role in restoring tissue homeostasis by modulating inflammation and wound healing. Specifically, an M1/M2 macrophage imbalance contributes to various inflammatory disorders. However, modulating macrophages with engineered nanomaterials remains a challenge. In this study, apoptotic-cell-inspired deformable phosphatidylserine (PS)- containing nanoliposomes (D-PSLs) were constructed to explore their interactions with macrophages, and evaluate their anti-inflammatory and pro-healing effects on chronic wounds in diabetic rats. We found that soft D-PSLs can persistently bind to macrophage membranes and enhance the anti-inflammatory and pro-healing responses of macrophages, which not only sheds new light on the design of therapeutic biomaterials based on regulating macrophages but also provide a promising biomimetic nano-therapeutic approach for chronic inflammatory injury.

Nepeta adenophyta Hedge (Lamiaceae) is an endemic therapeutic herb from Astore, Gilgit. This plant species has been reported among the local communities, especially for treating abdominal pain, kidney pain, menstrual pain, headache, and controlling bleeding disorders. Therefore, the scientific basis is provided for the relief of pain as it is used in various pain management among the natives, especially as ethnogynecological herbal remedy.

The Postural Awareness Scale (PAS) was developed among a sample of German speakers to measure self-reported awareness of body posture. The first aim of this study was to conduct an English translation and cross-cultural adaptation of the PAS. The second aim was to assess psychometric properties of the English version of the PAS.
