To assess the effect of the application of hyaluronic acid (HA) in conjunction with free gingival graft (FGG) on postoperative patient discomfort and wound healing.

A total of 24 healthy non-smoker patients requiring FGG were recruited for the study. Subjects were randomly assigned into study groups, local application of HA on both donor and recipient sites and control group, application of normal saline. The FGG dimensions were evaluated using digital photographs. Post-operative pain was evaluated for 14days. Color matching and patient satisfaction were evaluated at 6months.

In this randomized clinical trial, 21 patients (mean age 23years, (15 females and 6 males) completed the study. Baseline characteristics were comparable across treatment groups. Pain scores in donor sites were statistically significant and higher in control group than study group until day 7 (p < 0.05). Mean of the surface area of the graft at baseline in study vs control group were (169 ± 21), (183 ± 22) (2mm), respectively. While at 6months, were (147 ± 30) and (139 ± 32) (2mm), in study and control group, respectively (p > 0.05). Color match showed no statistical significance difference.

Topical application of HA may exhibit significant improvement of postoperative pain and no significant difference in graft dimensions and patients' satisfaction.

Topical application of HA is recommended as a dressing material in FGG surgeries to reduce postoperative pain and accelerate healing.

To assess related studies and discuss the clinical implications of endodontic access cavity (AC) designs.

A systematic review of studies comparing the fracture resistance and/or endodontic outcomes between different AC designs was conducted in two electronic search databases (PubMed and Web of Science) following the PRISMA guidelines. Study selection, data extraction, and quality assessment were performed. Meta-analyses were undertaken for fracture resistance and root canal detection, with the level of significance set at 0.05 (P = 0.05).

A total of 33 articles were included in this systematic review. The global evaluation of the risk of bias in the included studies was assessed as moderate, and the level of evidence was rated as low. Four types of AC designs were categorized traditional (TradAC), conservative (ConsAC), ultraconservative (UltraAC), and truss (TrussAC). Their impact on fracture resistance, cleaning/disinfection, procedural errors, root canal detection, treatment time, apical debris extrue the practitioner for the optimal extent of AC outline form which varies from case to case.
Maintaining the extent of AC design as small as practical without jeopardizing the root canal treatment quality remains a pragmatic recommendation. Different criteria can guide the practitioner for the optimal extent of AC outline form which varies from case to case.
The aim of this paper is to present recommendations from an international workshop which evaluated the methodology and reporting of caries diagnostic studies. As a unique feature, this type of studies is focused on caries lesion detection and assessment, and many of them are carried out in vitro, because of the possibility of histological validation of the whole caries spectrum. This feature is not well covered in the existing reporting STARD guideline within the EQUATOR Network.

An international working group of 13 cariology researchers was formed. The STARD checklist was reviewed and modified for caries detection and diagnosis purposes, in a three-step process of evaluation, consensual modification, and delivery during three 2-day workshops over 18months. Special attention was paid to reporting requirements of caries studies that solely focus on reliability.

The STARD checklist was modified in 14/30 items, with an emphasis on issues of sample selection (tooth selection in in vitro studies), blinding, and detailed reporting of results.

Following STARCARDDS (STAndard Reporting of CAries Detection and Diagnostic Studies) is expected to result in complete reporting of study design and methodology in future caries diagnosis and detection experiments both in vivo and in vitro, thus allowing for better comparability of studies and higher quality of systematic reviews.

Standardization of caries diagnostic studies leads to a better comparability among future studies, both in vivo and in vitro.

This study is novel from the Bangladeshi perspective. In this study, phytoplankton cell density and diversity were studied with particular reference to the functional groups (FGs) approach during pre-monsoon, monsoon, and post-monsoon at four sampling stations in Karatoya River, Bangladesh. A total of 54 phytoplankton species were recorded under four classes, viz. Chlorophyceae (21 species) Cyanophyceae (16 species), Bacillariophyceae (15 species), and Euglenophyceae (2 species). A significantly higher total cell density of phytoplankton was detected during the pre-monsoon season (24.20 × 103 cells/l), while the lowest in monsoon (9.43 × 103 cells/l). The Shannon-Wiener diversity index varied significantly (F = 16.109, P = 000), with the highest value recorded during the post-monsoon season. Analysis of similarity (ANOSIM) identified significant variations among the three seasons (P  less then  0.0001, R = 0.9518). The similarity percentage (SIMPER) analysis pinpointed Ulothrix spp. (Melosira granulate and Cymbella spp.) as the most contributory species are causing such a noticeable difference. Fifty-four phytoplankton species recorded during the study period were classified into 20 functional groups, whereas D/J/M/MP/X1 was considered the most abundant FG in the Karatoya River. FGs of the Karatoya River were influenced mainly by the nutrients (PO4-P and NO3-N) enrichments. As a novel investigation on FGs of phytoplankton in Bangladesh, this study recommends additional surveys in other rivers and floodplains to improve our understanding of phytoplankton diversity and functional groups.Chikungunya virus (CHIKV) is a mosquito-borne emerging pathogen that is transmitted to humans through the bite of female Aedes mosquitoes. CHIKV infection has become a major public health concern worldwide, as it has a significant impact on the healthcare system. Since 2004, the virus has emerged in Africa and subsequently spread to countries located near the Indian Ocean, including India, and to Europe, the Americas, and Asia. In Thailand, a large CHIKV outbreak occurred during 2008-2009 and was caused by a virus originating from the east/central/south African (ECSA) CHIKV genotype. Since then, the ECSA genotype of CHIKV has continued to circulate and has caused sporadic cases in different areas in Thailand. Approximately 20,000 reported cases have been confirmed by the Bureau of Epidemiology, Ministry of Public Health, Thailand, from January 1, 2018 to July 31, 2020. https://www.selleckchem.com/products/gdc-0068.html However, the causes of this CHIKV re-emergence remain unclear. To obtain a better understanding of CHIKV circulation during the recent outbrealonged to the Indian Ocean clade of the ECSA genotype. The results obtained in this study provide detailed information on the molecular characteristics and evolution of currently circulating CHIKV strains in Thailand, which are useful for developing prevention and control strategies.A novel double-stranded RNA virus was isolated and identified from Beauveria bassiana Vuillemin, derived from the muscardine cadaver of an Ostrinia furnacalis larva in China. The virus contains six dsRNAs, and each viral dsRNA contains only one open reading frame (ORF). As in other polymycoviruses, dsRNA1 encodes an RNA-dependent RNA polymerase (RdRp), dsRNA3 encodes a methyltransferase (MTR), and dsRNA4 encodes a proline-alanine-serine-rich protein. A BLASTp search revealed that the viral RdRp domain showed 79.43%, 79.04%, and 59.05% sequence identity to Beauveria bassiana polymycovirus 2 and 3 (BbPmV-2, BbPmV-3) and Magnaporthe oryzae polymycovirus 1 (MoPmV-1), respectively. Phylogenetic analysis based on RdRp sequences showed that the phylogenetically closest relatives of this virus are BbPmV-2, BbPmV-3, and MoPmV-1. This virus, along with previously ill-defined polymycoviruses (BbPmV-2 and BbPmV-3), appears to belong to an as-yet-unestablished species. The findings further suggest that the virus is a new member of the genus Polymycovirus within the family Polymycoviridae, and we have named it "Beauveria bassiana polymycovirus 4" (BbPmV-4). However, the sixth dsRNA is a defective RNA with the same sequence as that of dsRNA4 except for a deletion of 312 bp from nt 185 to nt 496, but it still contains a complete ORF. To our knowledge, this is the first report of the existence of a defective RNA in a polymycovirus.It is not wrong to say that there are no application standards or best practices in balneotherapy considering traditional applications. There is not enough information about how changes in body temperature, duration, and frequency of exposure to heat affect therapeutic outcomes of balneotherapeutic applications. Body core temperature (BCT) is probably the best parameter for expressing the heat load of the body and can be used to describe the causal relationship between heat exposure and its effects. There are several reasons to take BCT changes into account; for example, it can be used for individualized treatment planning, defining the consequences of thermal effects, developing disease-specific approaches, avoiding adverse effects, and designing clinical trials. The reasons why BCT changes should be considered instead of conventional measures will be discussed while explaining the effects of balneotherapy in this article, along with a discussion of BCT measurement in balneotherapy practice.
COVID-19 spreads through aerosols produced in coughing, talking, exhalation, and also in some surgical procedures. Use of CO
laser in laryngeal surgery has been observed to generate aerosols, however, other techniques, such cold dissection and microdebrider, have not been sufficiently investigated. We aimed to assess whether aerosol generation occurs during laryngeal operations and the effect of different instruments on aerosol production.

We measured particle concentration generated during surgeries with an Optical Particle Sizer. Cough data collected from volunteers and aerosol concentration of an empty operating room served as references. Aerosol concentrations when using different techniques and equipment were compared with references as well as with each other.

Thirteen laryngological surgeries were evaluated. The highest total aerosol concentrations were observed when using CO
laser and these were significantly higher than the concentrations when using microdebrider or cold dissection (p < down algorithm from CO2 laser to cold instruments and microdebrider is recommended to lower the risk of airborne infections among medical staff.
