Clinical relevance of distolingual roots and periodontal status in mandibular first molars: a cross-sectional study employing CBCT analysis.

: Distolingual root of the permanent mandibular first molar (PMFM-DLR) has been frequently reported, which may complicate the treatment of periodontitis. This study aimed to assess the morphological features of PMFM-DLR and investigate the correlation between the morphological features of PMFM-DLR and periodontal status in patients with Eastern Chinese ethnic background. : A total of 836 cone beam computed tomography (CBCT) images with 1497 mandibular first molars were analyzed to observe the prevalence of PMFM-DLR at the patients and tooth levels in Eastern China.

miR-378 associated with proliferation, migration and apoptosis properties in A549 cells and targeted NPNT in COPD.

Background: microRNAs contribute to the development and progression of chronic obstructive pulmonary disease (COPD). However, the underlying molecular mechanisms are largely unclear. The goal of this study was to investigate the roles of miR-378 in alveolar epithelial type II cells and identify molecular mechanisms which contribute to the pathogenesis of COPD.

Molecular targets of primary cilia defects in cancer (Review).

Primary cilia are hair‑like organelles that are present on the majority of mammalian cells. They are regarded as the regulatory 'hub' of cell functions due to their indispensable roles for several signaling pathways, such as Hh and Wnt pathways. Originally, cilia defects were found to cause a panoply of human diseases commonly referred to as 'ciliopathies'.

Activation of EGFR-Aurora A induces loss of primary cilia in oral squamous cell carcinoma.

Objective: Primary cilia, evolutionally conserved organelles involving multiple cell functions, are frequently lost in various cancers. However, little is known about the role of primary cilia in oral squamous cell carcinoma (OSCC).

Methods: Immunofluorescence staining was applied to detect primary cilia in normal, oral leukoplakia (OLK) and OSCC tissues.

Associations of PER3 polymorphisms with clopidogrel resistance among Chinese Han people treated with clopidogrel.

Background: Changes in circadian rhythm are related to various diseases, such as immune system diseases and cardiovascular diseases. The PERIOD3 (PER3) clock gene is one of the most important genes in the rhythm regulation system. Our goal was to evaluate the possible association between the PER3 rs228729 (T/C) polymorphism or PER3 rs2797685(T/C) polymorphism and clopidogrel resistance (CR) and to study the impact of clinical baseline data on clopidogrel resistance.

RACK1 promotes cancer progression by increasing the M2/M1 macrophage ratio via the NF-κB pathway in oral squamous cell carcinoma.

Receptor for activated C kinase 1 (RACK1) has been shown to promote oral squamous cell carcinoma (OSCC) progression, and RACK1 expression levels have been negatively correlated with prognosis in patients with OSCC. Here, we investigated the impact of RACK1 OSCC expression on the recruitment and differentiation of tumor-associated macrophages. High RACK1 expression in OSCC cells correlated with increased M2 macrophage infiltration in tumor samples from a clinical cohort study.

Exosomal miRNAs as potential biomarkers for acute myocardial infarction.

microRNAs (miRNAs) can be used as biomarkers for acute myocardial infarction (AMI). However, few reports have focused on the value of exosomal miRNAs in the mechanism of the pathophysiological process from stable coronary artery disease (SCAD) to AMI. Exosomes were isolated via ultracentrifugation after serum samples were collected.

The significance of PA28γ and U2AF1 in oral mucosal carcinogenesis.

Objective: Proteasome activator 28γ (PA28γ) upregulation plays a critical role in the carcinogenesis of many malignancies, including oral cancer. We aim to screen the related genes of PA28γ and investigate their function in oral mucosa carcinogenesis.

Materials And Methods: Bioinformatics analysis was performed to screen the related genes of PA28γ.

Hypomethylation of the Toll-like receptor-2 gene increases the risk of essential hypertension.

Studies on the etiology of essential hypertension (EH) have demonstrated that chronic inflammation contributes to the onset and development of elevated blood pressure. Toll‑like receptors (TLRs), important immune receptors, serve a role in chronic inflammation and are associated with EH. In the present study, 96 patients with EH, and 96 age‑ and sex‑matched healthy controls were recruited, and eight cytosine‑phosphate‑guanine (CpG) dinucleotides (CpG1‑8) were analyzed using bisulfite pyrosequencing technology.

Folate receptor-targeted ultrasonic PFOB nanoparticles: Synthesis, characterization and application in tumor-targeted imaging.

In this study, we aimed to determine an effective strategy for the synthesis of folate receptor (FR) targeted-nanoparticles (FRNPs). The nanoparticles used as ultrasound contrast agents (UCAs) were composed of a liquid core of perfluorooctyl bromide (PFOB) liposome and a targeted shell chemically conjugated with folic acid (FA) and polyethylene glycol (PEG). This was done in order to avoid recognition and clearance by the mononuclear phagocyte system [also known as the reticuloendothelial system (RES)] and enhance the targeting capability of the nanoparticles to tumors overexpressing folate receptor (FR).

Preliminary analysis of the association between methylation of the ACE2 promoter and essential hypertension.

The aim of the present study was to investigate whether methylation of the angiotensin I converting enzyme 2 (ACE2) promoter increases the risk of essential hypertension (EH). A total of 96 patients with EH were recruited and 96 sex‑ and age‑matched healthy controls. Methylation of 5 CpG dinucleotides in the ACE2 promoter was quantified using bisulfite pyrosequencing.

Interactions between Promoter Methylation and Smoking Increase Risk of Essential Hypertension.

Aldosterone synthase (CYP11B2) is closely linked to essential hypertension (EH). However, it remains unclear whether the methylation of the promoter is involved in the development of EH in humans. Our study is aimed at evaluating the contribution of promoter methylation to the risk of EH.

Association of SCNN1B promoter methylation with essential hypertension.

The amiloride-sensitive sodium channel beta subunit (SCNN1B) gene encodes the beta subunit of the epithelial sodium channel, which is involved in blood pressure homeostasis. The aim of the present study was to investigate the association between SCNN1B gene promoter methylation and essential hypertension (EH), and to explore whether SCNN1B methylation was altered by antihypertensive therapy. The present study recruited 282 individuals: 94 controls, 94 incident cases and 94 prevalent cases.

Association of AGTR1 Promoter Methylation Levels with Essential Hypertension Risk: A Matched Case-Control Study.

Unlabelled: The purpose of the present study was to investigate whether methylation of the angiotensin II type 1 receptor (AGTR1) promoter contributed to the risk of essential hypertension (EH). A total of 96 EH cases and 96 gender- and age-matched healthy controls were recruited. Methylation of 8 CpG dinucleotides (CpG1-8) in the AGTR1 promoter was examined using the bisulphite pyrosequencing technology.

The effects of Er:YAG on the treatment of peri-implantitis: a meta-analysis of randomized controlled trials.

A systematic electronic literature search was conducted to identify randomized clinical trials (RCTs), followed by a manual search.

Paeoniflorin inhibits pulmonary artery smooth muscle cells proliferation via upregulating A2B adenosine receptor in rat.

Paeoniflorin (PF), which is the main active ingredient in the root of Paeonia Radix, has many pharmacological effects. Here, we investigated the effect of PF on rat pulmonary artery smooth muscle cells (PASMCs) under hypoxic conditions and explored the mechanisms of the effects. The anti-proliferative effect of PF increased in a dose dependent manner.
