Enamel matrix derivative expedites osteogenic differentiation of BMSCs via Wnt/β-catenin pathway in high glucose microenvironment.

Introduction: The influence of enamel matrix derivative (EMD) on proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) was explored in high glucose (HG) microenvironment with interaction of Wnt/β-catenin pathway.

Materials And Methods: Extraction of BMSCs from Sprague-Dawley rats, culture, and identification were manifested. The cells were treated with different concentration of EMD in HG to figure out the most available concentration for proliferation and osteogenic differentiation.

The Systemic Immune-Inflammation Index and Albumin as Prognostic Predictors in Laryngeal Carcinoma.

The local corrosion behavior and mechanism of Ni-P coatings in a 3.5 wt% sodium chloride solution with different flow speeds (0 m s, 0.5 m s, 1 m s) were investigated through a wire beam electrode (WBE) with morphological, elemental and electrochemical analyses as well as numerical simulations.

Basal cell adenoma in the parapharyngeal space resected via trans-oral approach aided by endoscopy: Case series and a review of the literature.

Rationale: Basal cell adenoma (BCA) is a rare benign salivary gland tumor. It is difficult to be completely resected when arising in parapharyngeal space. A contemporary trend is to develop minimally invasive approaches on the premises of safety and complete resection.

Background: Nasal-type natural killer T-cell lymphoma involving the larynx is uncommon. Our search revealed only 12 cases reported previously in the English-language literature.

Case Report: We report a case of laryngeal NKTCL.

Metastatic squamous cell carcinoma of the gingiva appearing as a solitary branchial cyst carcinoma: diagnostic role of PET/CT.

We herein present a case of a left cervical cystic mass, for which the initial pathological diagnosis was branchial cleft cyst carcinoma (following complete mass excision). Thorough postoperative examinations, including with FDG positron emission tomography/computed tomography (PET/CT), revealed a primary tumor in the retromolar region of the left mandible. A 52-year-old female presented with a 2-month history of a painless, progressively enlarged left-sided neck mass.

Spindle cell rhabdomyosarcoma in the hypopharynx of an adult.

We herein present the first-reported case in the English-language literature of a spindle cell rhabdomyosarcoma in the hypopharynx of an adult. A 58-year-old male presented with a progressive, 7-month history of discomfort during swallowing, accompanied by hoarseness for 1 month. Computed tomography and magnetic resonance imaging revealed a tumor in the left pyriform sinus; frozen section evaluation suggested that it was rhabdomyosarcoma.

Apigenin suppresses GLUT-1 and p-AKT expression to enhance the chemosensitivity to cisplatin of laryngeal carcinoma Hep-2 cells: an in vitro study.

Glucose transporter-1 (GLUT-1) and PI3K/Akt are known to be closely involved in resistance to chemotherapy. Co-targeted therapy reducing GLUT-1 expression and PI3K/Akt pathway activity may overcome the chemoresistance of human cancers. Apigenin may inhibit the expression of GLUT-1 and the PI3K/Akt pathway.

Lanthanum ions intervened in enzymatic production and elimination of reactive oxygen species in leaves of rice seedlings under cadmium stress.

Rare earth elements at proper concentrations were observed to alleviate heavy metal stress. However, the potential mechanisms of alleviation are not clear. Thus, the present study focused on the mechanisms of lanthanum (La) ions on the generation and elimination of reactive oxygen species (ROS) production in leaves of rice seedlings hydroponically cultivated in 30 µM cadmium chloride (CdCl2) for 2 d.

The effects of temperature on the development of the moth Athetis lepigone, and a prediction of field occurrence.

Athetis lepigone (Möschler) (Lepidoptera: Noctuidae) is an important insect pest of corn crops in China. To determine the effect of temperature on A. lepigone growth, and to provide a forecasting model for this pest, the development and fecundity of A.

Laryngo-tracheobronchial amyloidosis: a case report and review of literature.

AMYLOIDOSIS is a benign process which can have systemic involvement. Though larynx is the common site of localized amyloidosis in the head and neck region,1 it was seldom reported with heterochronous implication of bilateral ventricles. Here we report a case of laryngeal amyloidosis heterochronously localized at bilateral ventricles with tracheobronchial involvement.

Glucose transporter-1 expression in CD133+ laryngeal carcinoma Hep-2 cells.

CD133 is a useful putative marker of cancer stem cells (CSCs) in human laryngeal tumors. Numerous studies have demonstrated that CD133+ CSCs possess higher clonogenicity, invasiveness and tumorigenesis compared with CD133- cells. Recently, interest in the Warburg effect in the microenvironment of CSCs has escalated.

Detection of minimum activity fragment of a novel Cry7Ab3 protein specific to Henosepilachna vigintioctomaculata (Coleopteran: Coccinellidae).

Bacillus thuringiensis Cry7Ab3 toxin has insecticidal activity against larvae of Henosepilachna vigintioctomaculata. Cry7Ab3 toxin is solubilized under alkaline condition and activated by proteases within the larval gut. In order to assess the functions of the N- and C-terminal regions, several N- and C-terminal truncated forms of Cry7Ab3 were constructed.

Effect of antisense oligodeoxynucleotides glucose transporter-1 on enhancement of radiosensitivity of laryngeal carcinoma.

Purpose: Laryngeal carcinomas always resist to radiotherapy. Hypoxia is an important factor in radioresistance of laryngeal carcinoma. Glucose transporter-1 (GLUT-1) is considered to be a possible intrinsic marker of hypoxia in malignant tumors.
