The Effect of Asymmetrical Occlusion on Surface Electromyographic Activity in Subjects with a Chewing Side Preference: A Preliminary Study.

The relationship between asymmetrical occlusion and surface electromyographic activity (sEMG) in people with different chewing preferences is not clear. In this study, the 5 s sEMG changes in the masseter muscle (MM), sternocleidomastoid (SCM), lateral (LGA), and medial (MGA) gastrocnemius muscles were recorded in controls, and subjects with chewing side preference (CSP) during clench with bilateral (BCR), left (LCR), and right (RCR) posterior teeth placement of cotton rolls. The images of the middle 3 s were selected and expressed as the root mean square (unit: μV/s).

[Periodontal health survey and analysis of influencing factors in 916 patients with type 2 diabetes].

Purpose: To investigate the periodontal health status of type 2 diabetes patients in the Endocrinology Department of Shanghai Sixth People's Hospital, to explore relevant influencing factors of chronic periodontitis, so as to provide epidemiological basis for targeted prevention and treatment of periodontal diseases in patients with type 2 diabetes.

Methods: Periodontal examination and questionnaire survey of patients with type 2 diabetes who visited the Endocrinology Department of Shanghai Sixth People's Hospital from November 2018 to December 2018 were conducted. Criteria in "Basic Methods for Oral Health Survey" recommended by WHO was referred to check and score the relevant periodontal indicators, including probing depth, bleeding on probing, attachment loss, calculus index, plaque index, etc.

Genome-Wide Identification and Expression Analysis of the MADS-Box Gene Family in Sweet Potato [ (L.) Lam].

MADS-box gene, one of the largest transcription factor families in plants, is a class of transcription factors widely present in eukaryotes. It plays an important role in plant growth and development and participates in the growth and development of flowers and fruits. Sweet potato is the seventh most important food crop in the world.

An Injectable Fibrin Scaffold Rich in Growth Factors for Skin Repair.

Platelet aggregates, such as PRP, PRF, and CGF, have been used alone or in combination with other grafting materials to enhance restoration outcomes. The process for preparing these autografting materials requires two-step centrifugation or specific centrifuges. In this study, we obtained an injectable fibrin scaffold (IFS) rich in growth factors by one-step centrifugation of whole blood from rabbits.

Ridge Alterations following Socket Preservation Using a Collagen Membrane in Dogs.

Background: The healing process following tooth extraction results in alveolar ridge resorption. The dimensional changes may complicate the subsequent implant procedure. Socket preservation using absorbable collagen membranes or a combination of membranes with calcium phosphate cement (CPC) particles might ensure that the alveolar ridge retains a suitable morphology for implant placement.

Masticatory efficiency in patients with partially dentate dentitions.

Objectives: To assess associations amongst masticatory performance, dental functional status, and perceived chewing problems with common soft and hard foods.

Materials And Methods: 387 adult participants with reduced natural dentitions were included and underwent an oral examination, completed a written structured questionnaire and performed a two-color chewing gum test for masticatory efficiency. A multivariate regression model was used to analyze associations between masticatory efficiency and a number of dental conditions, with age, gender and perceived chewing difficulties as background variables.

RNA-Seq investigation and in vivo study the effect of strontium ranelate on ovariectomized rat via the involvement of ROCK1.

Strontium ranelate (SrR) is an anti-osteoporosis drug with excellent osteogenic and angiogenic capacity. In this study, we aimed to investigate the osteogenesis and angiogenesis effects of SrR and the underlying mechanism involved. RNA-Seq was conducted to examine the effects of SrR on gene expression in ovariectomy rat bone marrow mesenchymal stem cells (OVX-rBMSCs).

Dose-dependent Effects of Strontium Ranelate on Ovariectomy Rat Bone Marrow Mesenchymal Stem Cells and Human Umbilical Vein Endothelial Cells.

In clinic, strontium ranelate (SrR) is a useful drug to treat osteoporosis by orally taken method, but some side effect appeared in recent years. The aim of this study is to evaluate the effectiveness and safety of SrR on cells by direct application, to study the possibility of local application of this drug. Qualitative ALP staining, quantitative ALP activity assay, alizarin red staining, realtime PCR and westernblot assay were used to evaluate the osteogenesis ability of SrR under normal or osteogenic induction environment of ovariectomy bone marrow mesenchymal stem cells (OVX-BMSCs).

[Influences of quercetin on contraction of small intestine smooth muscle of rabbits in vitro and its mechanism].

Objective: To observe the influences of quercetin (Que) on the contraction of small intestine smooth muscle of rabbits in vitro and explore the mechanism.

Methods: With the isothermal perfusion of small intestine in vitro. The influences of quercetin on the spontaneous contraction of small intestine and contraction induced by Ach, histamine and Bacl2 were observed and the mechanism of quercetin was studied.
