Background: Abnormalities of functional connectivity (FC) in certain brain regions are closely related to the pathophysiology of major depressive disorder (MDD). Findings are inconsistent with different presuppositions in regions of interest. Our research focused on voxel-wise brain-wide FC changes in patients with MDD in an unbiased manner.
Method: We examined resting-state functional MRI in 23 patients with MDD and 26 healthy controls. Imaging data were analyzed by using global-brain FC (GFC) and used to explore the correlation of abnormal GFC values with clinical variables.
Results: Increased GFC values in the left medial superior frontal gyrus (SFGmed) and decreased GFC values in the right supplementary motor area (SMA) were observed in the patients with MDD compared with the controls. The decreased GFC values in the right SMA had a positive correlation with vitamin D and Hamilton Anxiety Scale (HAM-A) scores.
Conclusion: Abnormal GFC in the hate circuit, particularly increased GFC in the left SFGmed and decreased GFC in the right SMA, appears to be a new sight for comprehending the pathological alterations in MDD.

Amidst global sustainability imperatives, this study pioneers a solid-state regeneration strategy that transforms spent LiCoO (LCO) cathodes into high-performance materials via amorphous lithium iron phosphate glass (LFPg)-driven structural reconfiguration. Unlike conventional recycling that decomposes cathodes, our approach leverages LFPg's defect-rich framework, high ionic conductivity, and dynamic interfacial activity to directly reconstruct degraded LCO crystals. The LFPg acts as a multifunctional repair agent: creating Li diffusion channels through disorder engineering, eliminating oxygen vacancies via atomic oxygen transfer, scavenging impurities (e.

With improved living standards and increased health awareness among Chinese residents, carbohydrate antigen 19-9 (CA 19-9) has become a routine marker in health examinations. Elevated CA 19-9 levels are frequently observed in clinical practice. Although chemiluminescence technology is widely recognized for its high sensitivity and specificity, it cannot eliminate interference, which may lead to deviations and misdiagnoses.

Objectives: To evaluate the influence of aging on color and optical properties of 3D printing resin-based dental restorative materials.
Methods: Four 3D printing resin-based dental restorative materials (DFT- Detax Freeprint Temp; FT- Formlabs Temporary CB; FP- Formlabs Permanent Crown; and GCT- GC TempPrint) were evaluated. The structures were printed using digital light processing (DLP) (DFT and GCT groups) and stereolithography (SLA) (FT and FP groups) technologies.

Objectives: The aim of this study is to conduct a linguistic-cultural validation for the French context, of the original Australian version of the Oral Health Assessment Tool (OHAT) scale.
Methods: The study design is a mixed retrospective-prospective psychometric and linguistic translation/validation/study of the Oral Health Assessment Tool. This validation involved two samples: a retrospective convenience sample of 1319 patients from the "Geriatric Frailty Clinic (GFC) for Assessment of Frailty and Prevention of Disability" and a prospective sample included 50 patients (34 from the long-term care unit and 16 from the neuro-locomotive follow-up care and rehabilitation unit).
