S-ketamine alleviates depression-like behavior and hippocampal neuroplasticity in the offspring of mice that experience prenatal stress.

Prenatal stress exerts long-term impact on neurodevelopment in the offspring, with consequences such as increasing the offspring's risk of depression in adolescence and early adulthood. S-ketamine can produce rapid and robust antidepressant effects, but it is not clear yet whether and how S-ketamine alleviates depression in prenatally stressed offspring. The current study incestigated the preliminary anti-depression mechanism of S-ketamine in prenatally stressed offspring, particularly with regard to neuroplasticity.

AZGP1 as a potential biomarker of IgA vasculitis with nephritis in a children‑based urinary proteomics study by diaPASEF.

The present study aimed to screen for potential biomarkers in the urine of immunoglobulin A vasculitis with nephritis (IgAVN) using parallel accumulation‑serial fragmentation combined with data‑independent acquisition (diaPASEF) proteomic approach. Urine proteomes of eight children with IgAVN and eight healthy children were identified by diaPASEF and all differential proteins were analyzed by Gene Ontology and Kyoto Encyclopedia of Gene and Genome. Then, the specific biomarkers of urine samples from 10 children with IgAVN, 10 children with IgAV and 10 healthy children were verified by ELISA.

Association of Bone Morphogenetic Protein (BMP)/Smad Signaling Pathway with Fracture Healing and Osteogenic Ability in Senile Osteoporotic Fracture in Humans and Rats.

BACKGROUND To investigate the effect of the BMP/Smad signaling pathway on fracture healing and osteogenic ability in senile osteoporotic fracture on humans and rats. MATERIAL AND METHODS Sixty-two patients and well-matched normal controls were enrolled for clinical observation. A rat model of senile osteoporotic fracture was established.

Characterizing the induction of diabetes in juvenile cynomolgus monkeys with different doses of streptozotocin.

Juvenile (2-23 years old) cynomolgus monkeys are frequently used as recipients in non-human primate islet transplantation studies. The aim of this study was to examine the effects of different doses of streptozotocin (STZ), and find the optimal dose for inducing diabetes in these monkeys. Fifteen juvenile (2-3 years old) cynomolgus monkeys were separated into three groups and administered with different doses of STZ (100, 68 or 60 mg kg(-1)).

Labeling of cynomolgus monkey bone marrow-derived mesenchymal stem cells for cell tracking by multimodality imaging.

Recently, transplantation of allogeneic and autologous cells has been used for regenerative medicine. A critical issue is monitoring migration and homing of transplanted cells, as well as engraftment efficiency and functional capability in vivo. Monitoring of superparamagnetic iron oxide (SPIO) particles by magnetic resonance imaging (MRI) has been used in animal models and clinical settings to track labeled cells.

Cells therapy for Parkinson's disease--so close and so far away.

One of the strategies of treating Parkinson's disease (PD) is the replacement of lost neurons in the substantia nigra with healthy dapamingergic cells. Potential sources for cells range from autologous grafts of dopamine secreting cells, fetal ventral mesencephalon tissue, to various stem cell types. Over the past quarter century, many experimental replacement therapies have been tried on PD animal models as well as human patients, yet none resulted in satisfactory outcomes that warrant wide applications.
