Impact of allogeneic dental pulp stem cell injection on tissue regeneration in periodontitis: a multicenter randomized clinical trial.

Periodontitis causes the destruction of tooth-supporting tissues, and current therapies for periodontal regeneration are invasive. In this study, a human dental pulp stem cell (DPSC; hDP-MSC) injection was developed to promote periodontal regeneration through a non-invasive procedure. A total of 132 patients with chronic periodontitis (158 teeth) from two centers in China were included.

Genetic analysis and identification of candidate genes for a narrow and long grain mutant () in rice.

Grain size is one of the components that determine the rice yield. Exploring more key genes that regulating grain size and analyzing their molecular mechanisms are of great importance for precision breeding of rice. In this study, we screened a mutant (narrow and long rain 1) with narrow and long grains by mutagenizing the japonica rice variety ZH11 with EMS.

A molecular framework for the GS2-SUG1 module-mediated control of grain size and weight in rice.

Grain size is a key agronomic traits that influence grain yield in crops. The transcription factor GS2/OsGRF4 can improve grain size and yield, but its underlying mechanism remains unclear. Here we report a suppressor of the gain-of-function allele GS2 (SUG1) that encodes a plant-specific protein DEP2/SRS1/EP2/OsRELA and acts as a transcriptional regulator.

Electronic vascular conduit for in situ identification of hemadostenosis and thrombosis in small animals and nonhuman primates.

Patients suffering from coronary artery disease (CAD) or peripheral arterial disease (PAD) can benefit from bypass graft surgery. For this surgery, arterial vascular grafts have become promising alternatives when autologous grafts are inaccessible but suffer from numerous postimplantation challenges, particularly delayed endothelialization, intimal hyperplasia, high risk of thrombogenicity and restenosis, and difficulty in timely detection of these subtle pathological changes. We present an electronic vascular conduit that integrates flexible electronics into bionic vascular grafts for in situ, real-time and long-term monitoring for hemadostenosis and thrombosis concurrent with postoperative vascular repair.

Cortical perforation promotes bone regeneration by enhancing nerve growth factor secretion.

Adequate blood supply around bone grafts is crucial in periodontal regenerative surgery. Research suggests that cortical perforation during surgery can stimulate angiogenesis and cell migration, increase blood supply to the surgical site, and promote local tissue regeneration. However, the effects of perforation on the local tissue microenvironment and the molecular mechanisms by which corticotomy promotes bone regeneration remain unclear.

Dopamine D receptors in the lateral habenula regulate anxiety-related behaviors in a rat model of Parkinson's disease.

Although the output of the lateral habenula (LHb) controls the activity of midbrain dopamine (DA) and 5-hydroxytryptamine (5-HT) containing systems, which are implicated in the pathophysiology of anxiety, it is not clear how activation and blockade of LHb D receptors affects anxiety-like behaviors, particularly in Parkinson's disease related anxiety. In this study, unilateral 6-hydroxydopamine lesions of the substantia nigra pars compacta (SNc) in rats induced anxiety-like behaviors, which attribute to hyperactivity of LHb neurons and decrease in the level of DA in the medial prefrontal cortex (mPFC), amygdala and ventral hippocampus (vHip) compared to sham-operated rats. Intra-LHb injection of D receptor agonist A412997 induced or increased the expression of anxiety-like behaviors, while injection of D receptor antagonist L741742 showed anxiolytic effects in sham-operated and the SNc-lesioned rats.

Association Between Blood-Brain Barrier Disruption and Stroke-Associated Pneumonia in Acute Ischemic Stroke Patients After Endovascular Therapy: A Retrospective Cohort Study.

Background: Stroke, particularly due to large vessel occlusion (LVO), is a major cause of mortality and disability globally. Endovascular therapy (ET) significantly improves outcomes for acute ischemic stroke (AIS) patients, but complications such as stroke-associated pneumonia (SAP) increase mortality and healthcare costs. This study investigates the association between blood-brain barrier (BBB) disruption and the increased risk of SAP and explores the relationship between BBB disruption and medium-term functional outcomes.

Robust topological insulating property in CX-functionalized III-V monolayers.

Two-dimensional topological insulators (TIs) show great potential applications in low-power quantum computing and spintronics due to the spin-polarized gapless edge states. However, the small bandgap limits their room-temperature applications. Based on first-principles calculations, a series of CX (X = H, F, Cl, Br and I) functionalized III-V monolayers are investigated.

High-pressure effects on the electronic properties and photoluminescence of Ag-doped CsCuI.

A giant intrinsic photovoltaic effect in atomically thin ReS.

The photovoltaic (PV) effect in non-centrosymmetric materials consisting of a single component under homogeneous illumination can exceed the fundamental Shockley-Queisser limit compared to the traditional p-n junctions. Two-dimensional (2D) materials with a reduced dimensionality and smaller bandgap were predicated to be better candidates for the PV effect with high efficiency exceeding that of traditional ferroelectric perovskite oxides. Here, we report the giant intrinsic PV effect in atomically thin rhenium disulfide (ReS) with centrosymmetry breaking.

The impacts of oral and gut microbiota on alveolar bone loss in periodontitis.

Periodontitis, a chronic infectious disease, primarily arises from infections and the invasion of periodontal pathogens. This condition is typified by alveolar bone loss resulting from host immune responses and inflammatory reactions. Periodontal pathogens trigger aberrant inflammatory reactions within periodontal tissues, thereby exacerbating the progression of periodontitis.
