Janus Nanoparticles for Dual Wavelength Surface Enhanced Raman Scattering Applications

Plasmonic nanostructures have been used to enhance Raman scattering by the virtue of surface plasmon resonances. This method of surface enhanced Raman spectroscopy (SERS) has paved the way for these plasmonic nanostructures to be used as potential SERS substrates in applications like bio-sensing, diagnostics and other applications. In order to optimize the SERS enhancement, the plasmon resonance of the nanostructures needs to be tuned. The usage of alloy nanoparticles has been an efficient method to achieve this. In this paper we study Ag-Cu alloy nanoparticles with Janus morphology and explore the possibility of tuning the plasmon resonance in order to utilize the nanostructures for dual wavelength SERS applications. © 2022 IEEE

Gastroesophageal Reflux Disease: A Review Of Symptomatic Management

Considered as a chronic illness, gastroesophageal reflux disease (GERD) has manifested itself as a widespread condition throughout the adult population. As a growing epidemic, GERD has reached a staggering prevalence of 10% to 20% in the Western world, by affecting up to 30 million people in the United States alone. 1 Sixty percent of individuals in an adult population will experience symptoms and the impact of GERD over a period of 12 months, whereas a remarkable 20% to 30% of individuals will have weekly symptoms. 2 This rapid increase in the prevalence of the disease requires equally rapid management techniques. Although the disease itself has no cure, management of symptoms and certain pharmacological and surgical advancements have allowed for individuals affected by GERD to receive specific treatment options sufficient for them to live a healthy life. In this paper, such management options will be examined and discussed in reference to their effectiveness in treating the symptoms presented in GERD patients

“Oral manifestations of HIV in accordance with CD4 count” – A cross-sectional study

Aims and Objectives: Mouth acts as a mirror for most of the underlying systemic diseases. Very few studies were done in south Indian population to observe the oral manifestations of human immunodeficiency virus (HIV) in relation to the cluster of differentiation 4 (CD4) count, and this study mainly highlights the presenting complaint of HIV patients during their dental visit. The study was aimed to determine the chief complaints of patients along with oral manifestations of HIV and correlate them to CD4 count. Materials and Methods: One hundred consecutive HIV-positive patients were considered for the study. All the oral manifestations and the chief complaints along with the calculated CD4 counts were noted and the results were correlated. Spearman correlation was used for CD4 count and other oral manifestations. Results: The mean CD4 counts were 421 cells/mm3 with a standard deviation (SD) of 404.34 for the most common oral manifestation of burning mouth and 176.5 cells/mm3 for the least common manifestation of malignancies. The CD4 count ranged from 120 to 1100 cells/mm3. The mean age and CD4 count were 38 years and 398.86, respectively. There was a statistically significant correlation with candidiasis and gingivitis, and the rest of the conditions were insignificant. Conclusion: The study results suggest that the chief complaint of presentation of an HIV-positive patient is pain due to carious teeth/abscess followed by burning mouth, with candidiasis being the most common disease
