Simplified Free Gingival Graft Around Implants Using Medical Grade Tissue Cyanoacrylate: A Case Series Report.

The free gingival graft (FGG) procedure using suturing techniques has been widely utilized to effectively increase the amount of attached keratinized gingiva. However, conventional suturing procedures are time-consuming and technique-sensitive. Simplified FGG procedure around teeth and dental implants using medical grade tissue adhesive (cyanoacrylate) is known to overcome drawbacks of traditional suture techniques.

Application of patch stimulator for intraoperative neuromonitoring during thyroid surgery: maximizing surgeon's convenience.

Background: Intraoperative neuromonitoring (IONM) is frequently used in thyroid surgery to reduce recurrent laryngeal nerve (RLN) injury by providing the surgeon with real-time feedback on nerve stimulation during dissection. We applied a disposable adhesive patch electrode to a dissecting instrument to transfer electrical stimulation to the dissecting instrument for IONM during thyroid surgery. This study aimed to evaluate the feasibility of using the patch stimulator approach for IONM during thyroid surgery.

Comparison of immunohistochemical analysis on sinus augmentation using demineralized tooth graft and bovine bone.

Objectives: The purpose of this animal research was to compare bone regeneration in augmented rabbit maxillary sinuses treated with demineralized particulate human-tooth graft and anorganic bovine bone by immunohistochemical analysis.

Materials And Methods: Piezoelectric bilateral sinus augmentation was performed in eight adult rabbits. In the control group, anorganic bovine was grafted in the maxillary sinus following elevation of the sinus membrane.

Decreased Expression of Sphingosine-1-Phosphate Receptor 1 in the Blood Leukocyte of Rheumatoid Arthritis Patients.

Sphingosine-1-phosphate (S1P) plays an important role in trafficking leukocytes and developing immune disorders including autoimmunity. In the synovium of rheumatoid arthritis (RA) patients, increased expression of S1P was reported, and the interaction between S1P and S1P receptor 1 (S1P1) has been suggested to regulate the expression of inflammatory genes and the proliferation of synovial cells. In this study, we investigated the level of S1P1 mRNA expression in the blood leukocytes of RA patients.

Diverse influences of androgen-disrupting chemicals on immune responses mounted by macrophages.

Androgen-disrupting chemicals (ADCs) can alter male sexual development. Although the effects of ADCs on hormone disruption have been studied, their influence on the immune response is not fully understood. To investigate the effects of ADCs on innate immunity, we tested eight candidate ADCs for their influence on macrophages by measuring nitric oxide (NO) production and cell viability.

Cavernous hemangioma of the tympanic membrane.

Cavernous hemangioma seems to most frequently arise in the posterior portion of the external auditory canal. However, they rarely occur in the tympanic membrane. A 49-year-old male patient was referred for evaluation of right-sided pulsatile tinnitus that he'd experienced for the previous 2 years.

Synthesis and evaluation of antitumor activity of novel 2-[Nmethyl-N-(4-methyl-1,3-benzothiazol-2-yl)aminomethyl]-5,8-diacyloxy-1,4-naphthoquinones.

A series of nine new compounds bridged by acyl groups at the 5,8-dihydroxyl group of DHNQ were synthesized and their cytotoxic activity against L1210 and P388 cancer cells was examined. Their antitumor action in mice bearing S-180 cells in the peritoneal cavity was also assessed. Increasing the size of the acyl group (compounds 7-9) up to propyl increased the antitumor activity (T/C value), whereas the cytotoxicity of these compounds was comparable against L1210 (lymphocytic leukemia) and P388 (lymphoid neoplasm) cancer cells.

A common mutation in cholesteryl ester transfer protein gene and plasma HDL cholesterol level before and after hormone replacement therapy in Korean postmenopausal women.

Background: Plasma cholesteryl ester transfer protein (CETP) functions to transfer cholesteryl ester from HDL to triglyceride-rich lipoproteins and regulates plasma HDL cholesterol level. A common mutation, the exon 15 A to G substitution at codon 442 (D442G) results in reduced plasma CETP activity and increased plasma HDL cholesterol level. Meanwhile, hormone replacement therapy (HRT) in postmenopausal women increases plasma HDL cholesterol level.

Pulmonary edema during pregnancy: unilateral presentation is not rare.

Information regarding pulmonary edema in obstetric patients is limited, especially its natural history as most cases are from tertiary care centers. The incidence, etiology, and course of pulmonary edema in all obstetric patients at a primary-secondary care center was studied prospectively among 29,621 obstetric cases in the past 3.5 years.
