The cannabinoid 1 receptor (CB1) is highly expressed in the central nervous system, where its physiological functions include the regulation of energy balance, pain, and addiction. Herein, we develop and validate a technique to use magnetic resonance imaging (MRI) to investigate the distribution of CB1 across mouse brains with high spatial resolution, expanding previously described in vitro studies and in vivo studies with positron emission tomography (PET). To support the MRI investigations, we developed a ligand that is specific for in vivo neuroimaging of CB1.

Communication between sympathetic nerves and the immune system is a crucial and active process during myocardial ischemia (MI), as myocardial damage and inflammatory stimuli concurrently occur. Sympathetic nerves undergo structural and functional changes after MI, leading to adverse left ventricular (LV) remodeling and heart failure (HF). The complex inflammatory response to MI, including local myocardial anti-inflammatory repair and systemic immune reactions, plays a key role in adverse LV remodeling.

Neutrophil extracellular traps (NETs) have been shown to promote the metastatic potential of many kinds of tumors. Our study aimed to investigate the role and mechanisms of NETs in lymph node metastasis (LNM) of cervical cancer (CCa), and evaluated the therapeutic value of targeting NETs in CCa. Immunohistochemistry demonstrated that neutrophil infiltration and NETs formation were increased in CCa patients with LNM, as well as confirming a positive correlation between S100A7 expression and neutrophil infiltration in CCa.

Article Synopsis
  • The study investigates the feasibility of local excision as a fertility-sparing surgery option for young women with early-stage cervical cancer, mainly focusing on patients aged 15-39 years.
  • Analyzing data from the SEER database, the research compares outcomes between local excision and hysterectomy across different types of cervical cancer and tumor characteristics.
  • Results indicate that local excision may offer better long-term survival for certain types of cervical cancer (like squamous cell carcinoma) compared to hysterectomy, particularly for patients with well-differentiated tumors, while being a viable option for stage IA and some stage IB patients.

Colony-stimulating factor 1 receptor (CSF1R) is a type III receptor tyrosine kinase that is crucial for immune cell activation, survival, proliferation, and differentiation. Its expression significantly increases in macrophages during inflammation, playing a crucial role in regulating inflammation resolution and termination. Consequently, CSF1R has emerged as a critical target for both therapeutic intervention and imaging of inflammatory diseases.

A technique is described for surgically exposing the dorsal root ganglion (DRG) of the lumbar-6 in a live, anesthetized laboratory mouse, along with the protocol for in vivo calcium imaging of the exposed DRG in response to various visceral and somatic stimuli. Pirt-GCaMP6s mice or C57BL6 mice intrathecally injected with AAV viruses packaged with GCaMP6s were utilized to capture Ca2+ transients. The amplitude of these transients indicates sensitivity to specific sensory modalities.

In the past 20 years, the acupuncture-moxibustion discipline has made a great progress in clinical research, method construction, standard formulation, guideline promotion, basic theory and key scientific issue research. Internationally, the development of acupuncture and moxibustion has gradually begun to pay more attention to the basic issues of the discipline itself from focusing on clinical evidence. The National Institute of Health of USA pays close attention to the construction of acupoint knowledge base and database and to the transformation of peripheral nerve stimulation techniques, which brings forth opportunities and challenges for the development of acupuncture-moxibustion discipline.
