Calcitonin gene-related peptide and brain-derived serotonin are related to bone loss in ovariectomized rats.

Objectives: Postmenopausal osteoporosis (PMO) and osteoporotic fracture seriously impair human health in developed countries. The present study aims to explore whether sensory nerves, calcitonin gene-related peptide (CGRP), and brain-derived serotonin are related to bone loss in ovariectomized (OVX) rats.

Methods: Female rats were grouped into the ovariectomized (OVX) and sham surgery (SHAM) groups.

Targeted therapy for intervertebral disc degeneration: inhibiting apoptosis is a promising treatment strategy.

Intervertebral disc (IVD) degeneration (IDD) is a multifactorial pathological process associated with low back pain (LBP). The pathogenesis is complicated, and the main pathological changes are IVD cell apoptosis and extracellular matrix (ECM) degradation. Apoptotic cell loss leads to ECM degradation, which plays an essential role in IDD pathogenesis.

Comparison between zero-profile and cage plate devices in the treatment of single-level cervical spondylopathy.

Objective: To compare the new zero-profile (Zero-P) fusion cage with regular cage and plate (CP) in the treatment of anterior cervical single-level cervical degenerative diseases.

Methods: Patients operated from January 2013 to August 2018 were enrolled. They were divided into the Zero-P group ( = 74 cases) and CP groups ( = 116 cases).

Exosomes in osteosarcoma research and preclinical practice.

Osteosarcoma (OS) is a rare soft-tissue malignant tumor with high lung metastasis and mortality rates. Preoperative chemotherapy, surgical resection of the lesion and postoperative chemotherapy are still the main treatments for osteosarcoma. The prognosis, however, is poor for patients with nonresectable, primary metastatic or relapsed disease.

Screening of osteoarthritis diagnostic markers based on immune-related genes and immune infiltration.

Osteoarthritis (OA) is a chronic degenerative disease of the bone and joints. Immune-related genes and immune cell infiltration are important in OA development. We analyzed immune-related genes and immune infiltrates to identify OA diagnostic markers.

Self-encapsulation liquid metal materials for flexible and stretchable electrical conductors.

A one-step strategy for fabricating flexible conductors phase separation is proposed, wherein, the liquid metal was implanted into polydimethylsiloxane, whose viscosity was changed using hexane. Such self-encapsulating composite exhibited good electronic and mechanical stability under mechanical cycles with no significant leaking of droplets during the testing process.
