Incidence and Outcomes of Infectious Keratitis After Corneal Collagen Cross-Linking Over 10 years From a Tertiary Care Center in South India.

Purpose: The purpose of this study was to report the incidence and outcomes of infectious keratitis after corneal collagen cross-linking (CXL) over 10 years in South India.

Methods: Patients who underwent CXL for progressive keratoconus between January 2011 and December 2020 and those with infectious keratitis were identified from an electronic database system. The clinical and microbiological profiles of those affected were extracted from the case files and included in the analysis, whereas viral keratitis was excluded.

Biomimetic Approach to Counter Streptococcus mutans Biofilm: An In Vitro Study on Seashells.

Aim This study aimed to investigate the anti-adherent property of the seashell surface and periostracum to prevent the formation of biofilm Materials and methods The seashells were initially collected from the natural urban beach, and an antibiofilm assay of the shells with and without periostracum was performed against . Furthermore, the seashells were analyzed with a stylus profilometer (Mitutoyo Surftest SJ-301, Mitutoyo America Corporation, Illinois, USA), atomic force microscope (AFM; Nanosurf Easyscan 2, Nanosurf Inc., USA), contact angle assessment, Fourier-transform infrared (FTIR) spectroscopy analysis, and scanning electron microscopy (SEM; JEOL USA, Inc.

Clinico-microbiological Profile of Nontuberculous Mycobacterial Keratitis.

Purpose: To assess the clinical and microbiological characteristics of nontuberculous mycobacterial (NTM) keratitis and to evaluate their response to medical therapy.

Methods: Sixteen patients of NTM keratitis were retrospectively reviewed from May 2014 to May 2019. Laboratory diagnosis were made using Ziehl-Nielsen acid-fast staining, routine culture method of isolation of nontuberculous mycobacteria and further identification of species by PCR (polymerase chain reaction)-based DNA sequencing targeting the heat shock protein-65 () gene.

Enhanced Adsorption of Lead (II) Ions from Aqueous Solution by a Chemically Modified Polyurethane.

Heavy metal pollution is a major threat to living systems due to increase in the industrial development worldwide. In this study, the adsorption of lead (II) ions by chemically modified polyurethane was reported. Polyurethane (PU) was chemically modified by sulphonation and chlorination to obtain sulphonated PU (SPU) and chlorinated PU (CPU).
