Dental pulp regeneration strategies: A review of status quo and recent advances.

Microorganisms, physical factors such as temperature or mechanical injury, and chemical factors such as free monomers from composite resin are the main causes of dental pulp diseases. Current clinical treatment methods for pulp diseases include the root canal therapy, vital pulp therapy and regenerative endodontic therapy. Regenerative endodontic therapy serves the purpose of inducing the regeneration of new functional pulp tissues through autologous revascularization or pulp tissue engineering.

[ acupuncture and moxibustion combined with cognitive training in treatment of post-stroke mild cognitive impairment: a randomized controlled trial].

Objective: To compare the clinical effect of (promoting the governor vessel and regaining consciousness) acupuncture and moxibustion combined with cognitive training and the simple cognitive training for post-stroke mild cognitive impairment (PSMCI).

Methods: Eighty-four patients with PSMCI were randomly divided into an observation group and a control group, with 42 cases in each group (3 cases in the observation group and 2 cases in the control group dropped off). The observation group was treated by acupuncture and moxibustion combined with cognitive training, acupuncture was given at Baihui (GV 20), Sishencong (EX-HN 1), Shenting (GV 24), etc.

A novel bee-friendly peptidomimetic insecticide: Synthesis, aphicidal activity and 3D-QSAR study of insect kinin analogs at Phe modification.

Background: As one of the most abundant and destructive pests in agriculture, aphids cause significant damage to crops due to their sap-taking and as virus vectors. Chemical insecticides are the most effective method to control aphids, but they bring insecticide resistance problems and harm nontarget organisms, especially bees, therefore the search for novel eco-friendly aphid control agents with low bee toxicity is urgent. Insect kinins are a class of small neuropeptides that control important functions in insects.

Chemical Composition and Antimicrobial and Antioxidant Activities of Essential Oil of Sunflower ( L.) Receptacle.

Sunflower ( L.) contains active ingredients, such as flavonoids, alkaloids and tannins. Nevertheless, few studies have focused on essential oil from the receptacle of sunflower (SEO).

Lower Expression of Ndfip1 Is Associated With Alzheimer Disease Pathogenesis Through Decreasing DMT1 Degradation and Increasing Iron Influx.

We have previously reported that high expression of divalent metal transporter 1 (DMT1) plays a crucial role in iron dyshomeostasis and β-amyloid (Aβ) peptide generation in the brain of Alzheimer's disease (AD). Recent studies have shown that Nedd4 family interacting protein 1 (Ndfip1) can degrade DMT1 through ubiquitination pathway and reduce the accumulation of intracellular iron. The present study aims to evaluate whether Ndfip1 is involved in AD pathogenesis through mediating DMT1 degradation and iron metabolism.

Suspended hybrid films assembled from thiol-capped gold nanoparticles.

In this work, we explored the formation processes of suspended hybrid thin films of thiol-capped Au nanoparticles (AuNPs) inside metal oxide tubular structures. We found that a balance between in-film interactions of the AuNPs and boundary interactions with metal oxides is a key in making these special organic-inorganic thin films. The hybrid films process many processing advantages and flexibilities, such as controllable film thickness, interfacial shape and inter-AuNPs distance, tuning of particle sizes, thiol population, chain lengths, and other new properties by introducing functional groups to thiol chains.

[CT and MRI in diagnosis of avascular necrosis of the vertebral body].

Objective: To evaluate the value of CT and MRI in the diagnosis of avascular necrosis of the vertebral body (ANV).

Methods: Twelve ANV patients were retrospectively analysed by their medical history, clinic manifestation, CT and MRI. Twelve AVN patients were treated with percutaneous vertebroplasty (PVP).
