The effect of low-level diode laser on COX-2 gene expression in chronic periodontitis patients

Abstract

Adjunctive treatments to scaling and root planing (SRP) such as lasers, have been utilized in the treatment of chronic periodontitis, mainly aiming to suppress and eliminate the bacteria, as well as enhancing the healing response. Eighty gingival papilla biopsy samples were obtained from 60 patients diagnosed with chronic advanced periodontitis; randomly assigned to three treatment groups (n = 20), as well as 20 subjects with no periodontal disease [group A]. Group B received SRP on a single quadrant/day for four consecutive days. On day 5, all quadrants were rescaled. Groups C and D received the same treatment as group B plus laser application with the low-level diode laser (630-670 nm, 1.875 J/cm2) for five and ten consecutive days, respectively. Papilla biopsies were obtained from subjects and evaluated by RT-PCR for expression of COX-2. The values in the control group were 0.028 0.014 and baseline values for the examined groups were 0.16 0.18. Significantly decreased level of COX-2 expression for groups C and D was found after treatment, while lowest average expression was found in the group that had the 10 laser treatments supplemental to SRP (0,035 0,014). The results of this study show suppression of COX-2 in gingival tissue after low-level laser treatment as adjunct to SRP.

Copper production landscapes of the South Caucasus

Publication date: September 2017

Studies of metal production frequently show a correlation between scale and organizational complexity. The remarkably rich landscapes of metal-producing sites of late 2nd-early 1st millennium BC Colchis provide an unprecedented opportunity to reexamine this apparent correlation. Investigations of copper smelting sites show that industries with a large aggregate output can be the result of numerous small groups of metalworkers acting independently. Spatial data on site distributions, estimates of productive output, and archaeometric data on ore procurement patterns were integrated to reconstruct the organization of production. Judicious use of a portable X-ray fluorescence spectrometer (pXRF) showed that not only were smelting sites highly dispersed, but also that metalworkers at different sites were using ores from geologically distinct deposits. This innovative approach helped to reconstruct the organization of production in a distinctive metal production landscape, bridging an enduring divide between landscape-scale and microscopic investigations of craft production.

A Case of Involuntary Rhythmic and Characteristic Tapping Sounds during Sleep

Involuntary motor disorders during sleep, such as sleep bruxism (SB) or facio-mandibular myoclonus (FMM), are observed in the oromandibuar area. This feature is repetitive and rhythmic movement produced by short muscle contraction. We report here a case of involuntary repetitive and unusual tapping sounds. The repetitive periodic jaw movement was observed every night but was absent during waking hours. The unusual sounds were confirmed both by audio recorder and the patient's bed partner.Video PSG showed spontaneous myoclonic EMG activity associated with lip movements and characteristic sounds from the patient's mouth.

Abstract
Zika virus (ZIKV) can be sexually transmitted and replicative particles were first detected in a semen sample from a patient during the 2013-14 French Polynesia outbreak. Here we describe the virus isolation from semen of a patient returning to Italy from Brazil.

Abstract
Dermatophytes comprising the genera Trichophyton, Microsporum, and Epidermophyton are important causes of superficial mycoses. The number of infected patients and the distribution of species of these organisms in our hospital were unknown. We therefore aimed to investigate the clinical pattern of dermatophyte infections and to identify the species of these dermatophytes at the Dermatological Clinic of the Hospital for Tropical Medicine, Faculty of Tropical Medicine, Mahidol University, Bangkok in a 1-year period. Twenty-six patients who had typical dermatophytosis lesions were recruited (27 specimens); 17 were female (65.38%) and 9 (34.62%) were male. The age range of the patients was 16-92 years. In total, nine dermatophyte isolates were identified by macroscopic and microscopic morphological characteristics. We found Microsporum canis (four isolates), Trichophyton mentagrophytes complex (one), Trichophyton rubrum (two), Trichophyton verrucosum (one), and Trichophyton tonsurans (one). The in vitro susceptibility profiles of seven antifungal agents against the nine dermatophytes were as follows (minimum inhibitory concentration ranges in μg/ml): The results were as follows (MIC ranges in μg/ml): ciclopirox, ≤0.06-0.5, griseofulvin ≤0.06-0.5, itraconazole ≤0.002-0.06, posaconazole ≤0.015-0.03, voriconazole ≤0.02-≥1, fluconazole ≤0.08-8, and terbinafine ≤0.01-0.125. This study represents the current state of dermatophyte infections in a metropolitan area of Bangkok, Thailand.

ASBA Study Club – Register Now for the Best Non-Vendor Course of the Year

When you decide to attend a dental sleep educational course, where do you begin? You have to know who you're learning from, credentials/experience of the organization and its speakers, and the method of instruction that will provide you with the desired outcome. At the American sleep (ASBA) Study Club you will be educated from A-Z on how to build a million-dollar practice, from experts who are actually doing it in the industry, and who have created successful business models in various markets.

This learning experience is in an elite and non-vendor atmosphere, where practitioners who have built million-dollar practices will offer their combined experience in dental sleep medicine at an up-close, hands-on learning environment. The ASBA Study Club isn't a traditional lecture with speakers and presentations; it is a Q&A with real material, case studies and collaboration at a location where you aren't being bombarded by salesmen. You will return home with skills and knowledge you can apply to your practice, not another piece of equipment or subscription to something you won't be using in a month.

These mini-conferences are unique, very affordable, 100%-nonprofit events designed to help ASBA members and potential members enjoy continued prosperity & growth. Many have left the conference saying that it was the most vital, essential & powerful dental sleep learning event they've ever attended.  We feature Doctors from a wide range of markets who will share insight with you on how to grow your dental sleep practice. Hear accounts from real ASBA members! Learn from their successes at our Study Club! Join us in Phoenix, AZ on August 11-12, 2017 for the next ASBA study club by registering now as spots are limited!
