Clinical and Radiographic Evaluation of Soft Tissue and Bone Status in Immediate Loaded Implants Placed Following Their Extraction in the Maxillary Anterior Region.

Introduction: In the maxillary anterior region, teeth extraction leads to significant soft and hard tissue changes. Immediate implant placement following extraction aims to reduce bone loss and overall treatment time. However, it may result in adverse soft tissue changes impacting esthetics.

Impact of Crystallite Size and Phase Boundaries on Magnetic and Thermoelectric Properties of Cu-Added BiFeO.

In this study, bismuth ferrite (BFO) and copper-added BFO were synthesized using the coprecipitation method. The incorporation of copper into the BFO lattice led to a reduction in the phase percentage of BFO due to the early formation of CuBiO. X-ray diffraction analysis revealed a decrease in crystallite size up to 0.

Attribute-Based Adaptive Homomorphic Encryption for Big Data Security.

There is a drastic increase in Internet usage across the globe, thanks to mobile phone penetration. This extreme Internet usage generates huge volumes of data, in other terms, big data. Security and privacy are the main issues to be considered in big data management.

Gene Therapy Options as New Treatment for Inherited Peripheral Neuropathy.

Inherited peripheral neuropathy (IPN) is caused by heterogeneous genetic mutations in more than 100 genes. So far, several treatment options for IPN have been developed and clinically evaluated using small molecules. However, gene therapy-based therapeutic strategies have not been aggressively investigated, likely due to the complexities of inheritance in IPN.

Synthesis of Silica-Coated Magnetic Hydroxyapatite Composites for Drug Delivery Applications.

We have prepared a core-shell magnetic silica-coated hydroxyapatite, Fe₃O₄@SiO₂@HAp composite materials for pH-responsive drug delivery applications. Captopril (Cap) and ibuprofen (Ibu) were chosen as model hydrophilic and hydrophobic drugs, respectively. The drugs were encapsulated into the Fe₃O₄@SiO₂@HAp composite via electrostatic interactions with existing amine and carboxylic acid groups during calcium phosphate shell formation.

Comparative analysis of emm types, superantigen gene profiles and antibiotic resistance genes among Streptococcus pyogenes isolates from ocular infections, pharyngitis and asymptomatic children in south India.

Group A Streptococcus (Streptococcus pyogenes) is responsible for a wide array of infections and incidence is high in developing countries like India. Although distribution of emm types of S. pyogenes in India has been described, its association with the virulence genes and ocular isolates is less concentrated.

Effect of subinhibitory concentrations of fluoroquinolones on biofilm production by clinical isolates of Streptococcus pyogenes.

Background & Objectives: Subinhibitory concentrations (sub-MICs) of antibiotics, although not able to kill bacteria, but influence bacterial virulence significantly. Fluoroquinolones (FQs) which are used against other bacterial pathogens creates resistance in non-targeted Streptococcus pyogenes. This study was undertaken to characterize the effect of sub-MICs of FQs on S.

Emergence of methicillin-resistant, vancomycin-intermediate Staphylococcus aureus among patients associated with group A Streptococcal pharyngitis infection in southern India.

Beyond Staphylococcus aureus being an etiological agent for several serious clinical complications, the foot prints of S. aureus in pharyngitis infection has also been recently recognized. With due response to the fact, a prospective study was conducted between 2009 and 2010 to describe the molecular epidemiology of S.

Virulence and multidrug resistance patterns of Vibrio cholerae O1 isolates from diarrheal outbreaks of South India during 2006-2009.

A total of 31 Vibrio cholerae O1 (4- Inaba and 27- Ogawa serotype) isolates collected during a three-year period (2006-2009) from acute diarrheal cases in Tamil Nadu, India were analyzed for antibiotic resistance profiling, virulence-associated factors, genetic profiling by enterobacterial repetitive intergenic consensus sequence polymerase chain reaction (ERIC PCR), and biofilm-forming ability. Antibiotic resistance profile revealed that most of the strains have become multidrug-resistant strains. All the isolates are resistant to ampicillin and polymyxin B, 97% of the isolates are resistant to nalidixic acid, 90% to co-trimoxazole, 32.

Comparison of bacterial communities in the throat swabs from healthy subjects and pharyngitis patients by terminal restriction fragment length polymorphism.

Terminal restriction fragment length polymorphism (T-RFLP) analysis was applied to characterize bacterial flora present in the throats of healthy subjects and pharyngitis patients. The 16S rRNA genes of bacteria present in throat metagenome were amplified by PCR with 6-carboxy-fluorescein (6-FAM)-labeled universal forward primer (27 F) and a universal reverse primer (1513R). The 16S rDNAs were digested with restriction enzymes with 4-bp recognition sites (MspI or RsaI) and analyzed by using an automated DNA sequencer.

Characterization of biofilms in different clinical M serotypes of Streptococcus pyogenes.

Streptococcus pyogenes is a notorious human pathogen responsible for a wide array of infections. The ability of S. pyogenes to form biofilms is an innate property during the pathogenesis of invasive infections.

Development of species-specific primers for detection of Streptococcus pyogenes from throat swabs.

A species-specific molecular marker has been developed to detect the human pathogen Streptococcus pyogenes from throat swabs. Streptococcus pyogenes is an important pathogen among Gram-positive organisms. A rapid and simple diagnostic tool is of utmost importance for the identification of this pathogen.

Inhibition of Streptococcus pyogenes biofilm formation by coral-associated actinomycetes.

Streptococcus pyogenes biofilms tend to exhibit significant tolerance to antimicrobials during infections. We screened coral-associated actinomycetes (CAA) for antibiofilm activity against different biofilm forming M serotype of Streptococcus pyogenes. Actinomycetes isolated from the mucus of the coral Acropora digitifera were screened for antibiofilm activity against S.

Antibiofilm activity of coral-associated bacteria against different clinical M serotypes of Streptococcus pyogenes.

Streptococcus pyogenes is the frequent cause of purulent infections in humans. Formation of a biofilm is one of the important aspects of its pathogenicity. Streptococcus pyogenes biofilm communities tend to exhibit significant tolerance to antimicrobial challenge during infections.

Occurrence of Gluconacetobacter diazotrophicus in tropical and subtropical plants of Western Ghats, India.

Endophytic bacteria were isolated from the tissues of surface sterilized roots, stems, and leaves of fifty different crop plants. Phenotypic, biochemical tests and species-specific PCR assay permitted identification of four isolates of Gluconacetobacter diazotrophicus from root tissues of carrot (Daucus carota L.), raddish (Raphanus sativus L.
