ANALGESIC EFFECTS OF PREEMPTIVE CELECOXIB OR TRAMADOL/ACETAMINOPHEN ADDED TO STANDARD POSTOPERATIVE PAIN MANAGEMENT IN IMPACTED MANDIBULAR THIRD MOLAR EXTRACTION: A MULTICENTER, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED TRIAL.

Objectives: This study aimed to assess the efficacy and safety of adding single-dose preemptive celecoxib 200 mg (Cc) or tramadol 37.5 mg/acetaminophen 325.0 mg (T/A) to standard postoperative analgesia after impacted mandibular third molar extraction, a design not previously explored.

The effect of Schizophyllan on the differentiation of osteoclasts and osteoblasts.

Schizophyllan (SPG), a β-glucan from Schizophyllum commune, is recognized for its antioxidant, immunoregulatory, and anticancer activities. In this study, its effects on bone cells, particularly osteoclasts and osteoblasts, were examined. We demonstrated that SPG dose-dependently inhibited osteoclastogenesis and reduced gene expression associated with osteoclast differentiation.

Application of sequential multimodal analgesia before and after impacted mandibular third molar extraction: Protocol for a randomized controlled trial.

Background: Several analgesics have been applied under various protocols to control the moderate-to-severe postoperative pain caused by the surgical extraction of an impacted mandibular third molar. However, a consensus on optimal pain management while minimizing side effects is yet to be reached.

Methods: This multi-center, prospective, double-blind, randomized controlled trial aims to evaluate the efficacy and safety of sequential multimodal analgesia combined with postoperative zaltoprofen along with multiple preemptive analgesics.

Risk of acute and chronic coronary syndrome in a population with periodontitis: A cohort study.

Objective: To investigate the role of periodontitis in the risk of acute and chronic coronary syndrome with compounding factors, including sociodemographic factors and medication use.

Methods: This retrospective cohort study used nationwide, population-based data from the Korean National Health Insurance Service-Health Screening Cohort database (514,866 individuals, 40-79 years). Propensity score matching was used for analysis.

Effect of Decompression on Jaw Cystic Lesions Based on Three-Dimensional Volumetric Analysis.

: This study aimed to evaluate the effectiveness of decompression on jaw cysts according to various parameters by volumetric analysis using three-dimensional computed tomography. : Fifty patients who underwent surgical decompression of the jaw cystic lesion were selected, and their preoperative and postoperative computed tomography results between 3 and 27 months were collected. Volumetric analysis was performed to evaluate any differences in the rate of volumetric change according to the sex, age, initial volume of the lesion, duration, location of the lesion, tooth extraction, expansion of the cortical layer, and pathological diagnosis.

Comparison of RECIST 1.0 and RECIST 1.1 in Patients with Metastatic Cancer: A Pooled Analysis.

Background: We conducted this pooled analysis to investigate the impact of RECIST 1.1 on the selection of target lesions and classification of tumor response, in comparison with RECIST 1.0.

Three-dimensional mandibular change after sagittal split ramus osteotomy with a semirigid sliding plate system for fixation of a mandibular setback surgery.

Objective: This study proposes a new plate system, a sliding plate, after sagittal split ramus osteotomy (SSRO). The sliding plate was designed to adjust the spatial relationship between the proximal and distal segments during the postoperative period. This plate was used for mandibular setback surgery to minimize forward early relapse.

A Case of Aggressive NK/T-cell Lymphoma/Leukemia with Cutaneous Involvement in Adolescence.

NK/T-cell lymphoma (NKTCL) is characterized by the expression of the NK-cell antigen CD56. Non-nasal NK/T-cell lymphomas are subdivided into primary cutaneous and 4 subtypes of secondary cutaneous lymphomas; nasal type, aggressive, blastic (blastoid), and other specific NK-like cell lymphoma. Aggressive NK/T-cell lymphoma/leukemia is a rare leukemic variant of nasal type NKTCL.

The fast skeletal muscle myosin light chain is differentially expressed in smooth muscle cells of OVA-challenged mouse trachea.

In a search for new molecular pathways associated with asthma, we performed an mRNA differential display analysis using total RNA extracted from the tracheal tissues of ovalbumin (OVA)-challenged mice and sham controls. cDNAs corresponding to mRNAs for which expression levels were altered by OVA-challenge were isolate and sequenced. Twenty-eight genes differentially expressed in sham and OVA challenged mice were identified.

A Case of Axillary Adenoid Basal Cell Carcinoma.

Basal cell carcinoma (BCC) is the most common skin cancer with a steadily increasing incidence. Ultraviolet radiation is considered the single most important risk factor for BCC, because the tumor occurs most frequently in sun-exposed areas of the body, with approximately four of five BCCs occurring on the face. BCC occurs infrequently in non-sun-exposed skin.

Combined micro-Raman/UV-visible/fluorescence spectrometer for high-throughput analysis of microsamples.

Combined micro-Raman/UV-visible (vis)/fluorescence spectroscopy system, which can evaluate an integrated array of more than 10,000 microsamples with a minimuma size of 5 microm within a few hours, has been developed for the first time. The array of microsamples is positioned on a computer-controlled XY translation microstage with a spatial resolution of 1 mum so that the spectra can be mapped with micron precision. Micro-Raman spectrometers have a high spectral resolution of about 2 cm(-1) over the wave number range of 150-3900 cm(-1), while UV-vis and fluorescence spectrometers have high spectral resolutions of 0.

Production of bioactive human granulocyte-colony stimulating factor in transgenic rice cell suspension cultures.

Human granulocyte-colony stimulating factor (hG-CSF), a human cytokine, was expressed in transgenic rice cell suspension culture. The hG-CSF gene was cloned into the rice expression vector containing the promoter, signal peptide, and terminator derived from a rice alpha-amylase gene Amy3D. Using particle bombardment-mediated transformation, hG-CSF gene was introduced into the calli of rice (Oryza sativa) cultivar Dong-jin.

Titanium dioxide particle-induced goblet cell hyperplasia: association with mast cells and IL-13.

Background: Inhalation of particles aggravates respiratory symptoms including mucus hypersecretion in patients with chronic airway disease and induces goblet cell hyperplasia (GCH) in experimental animal models. However, the underlying mechanisms remain poorly understood.

Methods: To understand this, the numbers of goblet cells, Muc5ac (+) expressing epithelial cells and IL-13 expressing mast cells were measured in the trachea of sham or TiO2 particles-treated rats using periodic acid-Schiff, toluidine blue and immunohistochemical staining.
