渐开线塑料齿轮齿廓偏差影像法测量的不确定度和抽样检验统计特性
Jixie chuandong, 2012 Applying projection method,the involute plastic gear tooth profile deviation is measured.As plastic gear tooth profile is much influenced by mechanical stress and thermal stress in machining,thus causing more tooth profile strain,to reflect precisely the

Two-parameter Envelope Calculation for the Profile of Worm Grinding Wheel and Dressing Method
Jixie chuandong, 2022 A mathematical model for tooth profile curve of cylinder gear with high-order modification gear surface is established. Applying two-parameter envelope theory to determine the meshing relationship between worm grinding wheel and helical gears，the ...

Advanced Science, EarlyView.Schematic diagram showing compressive stress triggers glycolytic reprogramming and lactate accumulation in macrophages. Lactate mediates TRAF6 lactylation at K171/K180 dual sites, which enhances its K63‐linked ubiquitination to activate the NF‑κB pathway and promote M1 polarization. This cascade drives orthodontic tooth movement (OTM) and alveolar bone

Advanced Science, EarlyView.Frontal lobe traumatic brain injury is associated with hyperactivity of an insular–orbitofrontal circuit in both patients and mice. By combination of integrating functional imaging, cell‐type–specific circuit manipulation, single‐cell transcriptomics, and whole‐cell recordings, this work identifies the downregulation of the potassium channel KCNC3 in ...

ATL2 Recruits TRAK1 to Promote Mitochondrial Transport at ER–Mitochondria Contact Sites
Advanced Science, EarlyView.ABSTRACT Mitochondrial transport and distribution are crucial for cellular homeostasis, yet whether and how they are regulated by endoplasmic reticulum (ER)–mitochondria contact sites remains unclear. Here, we demonstrate that the ER protein atlastin‐2 (ATL2) orchestrates mitochondrial transport and distribution by promoting assembly of the transport ...

TH17–Associated Polyamine Metabolism‐Guided Nanozyme Promotes Alveolar Bone Repair in Periodontitis
Advanced Science, EarlyView.A pronounced TH17‐skewed immune response is identified in experimental periodontitis, and enrichment of the polyamine pathway is observed during TH17 differentiation, suggesting its potential as an immunometabolic target. Inspired by these findings, DFMO@Ui‐Mn is developed as a therapeutic platform combining cascade ROS scavenging with immunometabolic ...

Annals of Neurology, EarlyView.Repeat expansion disorders frequently involve peripheral neuropathy, yet mechanisms remain unclear. Using a spinocerebellar ataxia type 3 (SCA3) Knock‐In Atxn3Q300/Q6, we identify progressive sensorimotor deficits, peripheral nerve pathology, and dorsal root ganglia RNA splicing dysregulation.

Modified Titanium Dental Implants: The Current Progress of Soft‐Tissue Integration Methods
Advanced NanoBiomed Research, EarlyView.Dental implants are an established solution for tooth loss, yet achieving soft tissue integration (STI) around the transmucosal region remains a challenge. The natural tooth–gingiva interface is poorly replicated on titanium implants. This review explores surface modification strategies, ranging from surface chemistry and topography to biological ...
