Introduction: The extensive plaque formation on dental restoratives may contribute to secondary caries or periodontal inflammation. Therefore, it is important to know how different types of dental restoratives may prevent or promote the accumulation of microorganisms. Hence, this study aims to evaluate the oral hygiene and microbial adhesion on the titanium (Ti)-coated stainless steel crown (Ti-coated SSC) and conventional SSC on a primary molar.
View Article and Find Full Text PDFIntroduction: Stainless steel crowns (SSCs) are the most durable and effective restorations for primary teeth. Titanium-coated SSCs are newer on the market, and this study was conducted to assess the amount of nickel (Ni) and titanium ions released from titanium-coated SSCs, with and without trim, in artificial saliva.
Materials And Methods: A total of 60 titanium-coated SSCs were divided into two groups-group I ( = 30, without trim) and group II ( = 30, with trim) and were immersed in 5 mL artificial saliva.
mRNA in eukaryotic cells is packaged into highly compacted ribonucleoprotein particles (mRNPs) in the nucleus and exported to the cytoplasm for translation. mRNP packaging and export require the evolutionarily conserved transcription-export (TREX) complex. TREX facilitates loading of various RNA-binding proteins on mRNA through the action of its DDX39B subunit.

Using the Auxin-Induced Degron (AID) system to rapidly degrade proteins, we show that among the nucleoporins localized at the nucleoplasmic side of the NPC, TPR is the key nucleoporin required for nuclear export of influenza virus mRNAs. TPR recruits the TRanscription and EXport complex (TREX)-2 to the NPC for exporting a subset of cellular mRNAs.

The eight genomic viral ribonucleoproteins (vRNPs) segments of IAV are transcribed and two generate viral mRNAs (M and NS) that undergo alternative splicing followed by export from the nucleus. The focus of this review is on viral RNA splicing and nuclear export.

Introduction: There are few reports of nocardial infections among the Indian population. We report this case because of its rarity and unique presentation and to highlight the role of cytology in diagnosis.
Case Details: A 74-year-old woman presented with fever and chest pain of a duration of 15 days.
Introduction: Visualizing the pulp cavity requires adequate knowledge of the size, morphology, and variation of the root canals of primary teeth. The morphology of the root canals in deciduous teeth causes difficulties during endodontic treatment. There have not been many studies on root canal variations in primary teeth in the Indian population.

Vaccines are available but partially effective, and the number of antiviral medications is limited. Thus, it is crucial to develop therapeutic strategies to counteract this major pathogen.

Here, we show that infection of human lung epithelial cells with influenza A virus (IAV) also induces a broad program of alternative splicing of host genes. Although these splicing-regulated genes are not enriched for canonical regulators of viral infection, we find that many of these genes do impact replication of IAV.

This multi-faceted nature and the slow turnover of NPC components complicates investigations of how individual nucleoporins act in these diverse processes. To address this question, we apply an Auxin-Induced Degron (AID) system to distinguish roles of basket nucleoporins NUP153, NUP50 and TPR.

Categorical agreement (CA) between direct disk diffusion (dDD) and reference disk diffusion (rDD) may vary between laboratories.
Aims And Objectives: This study was designed to determine the CA and understand various types of errors associated with antibiotic organism combination, so that caution can be derived while interpreting and reporting dDD results in the earliest meaningful time frame.
Fusobacterium is a gram negative obligate anaerobic bacilli, a normal inhabitant of gastrointestinal tract, oropharynx and female genital tract. Here we report a case of Fourniers gangrene from which Fusobacterium varium has been isolated along with certain other pathogens. There are only a few reported cases of Fusobacterium varium in literature and it has never been reported from Fournier's gangrene.

Previously, we found that host proteins hnRNP K and NS1-BP regulate IAV M segment splicing, but the mechanistic details were unknown. Here we show NS1-BP and hnRNP K bind M mRNA downstream of the M2 5' splice site (5'ss).

Pulpectomy serves such a purpose using various materials and techniques to fill the canals of primary teeth. Aims: The aim of this study was to determine the efficacy of modified disposable syringe technique in root canals of primary molars using digital radiography when obturated with endoflas.

HAIs are mainly transmitted via the hands of healthcare workers (HCWs), and HCW compliance with hand hygiene (HH) practices is reportedly low. Therefore, multimodal interventions are needed to develop effective HH improvement strategies.

Methods: An HH audit was carried out October 2015-September 2016 in 18 locations for a total of 1,080 observation periods and 64,800 minutes of observation.
Chronic hepatitis C virus (HCV) infection represents a major health threat to global population. In India, approximately 15-20% of cases of chronic liver diseases are caused by HCV infection. Although, new drug treatments hold great promise for HCV eradication in infected individuals, the treatments are highly expensive.

The premature loss of second primary molar before the eruption of permanent first molar can create a significant arch space/tooth size discrepancy. Distal shoe space maintainer is a valuable part of the Paediatric Dentist's armamentarium in those cases where the second primary molar is prematurely lost and it helps to guide the first permanent molar into place.
