A pulsed dynamic light scattering (DLS) system, which would be potentially applied to nonlinear DLS with molecular selectivity, was developed by combining a sub-nanosecond pulsed laser with a software-based detection system. The distortion of the time correlation function due to the clipping effect in the photon counting module, and the resulting underestimation of the particle size, were successfully calibrated based on a theoretical simulation. The effective removal of random noises was also demonstrated via time gating synchronized to the laser pulses.

Objectives: This experimental study compared the accuracy of implant insertion using the free-hand (FH) technique, static computer-aided surgery (S-CAIS), or dynamic computer-assisted surgery (D-CAIS) and to evaluate the correlation of learning curves between surgeons' experience and surgical time.
Materials And Methods: Thirty-six models were randomly assigned to three groups (FH, n = 12; S-CAIS, n = 12; D-CAIS, n = 12). Each model was planned to receive four implants in the maxillary anterior and posterior regions.
A Study of Halide Ion Exchange-Induced Phase Transition in CsPbBr Perovskite Quantum Dots for Detecting Chlorinated Volatile Compounds.

The unique optical properties of perovskite quantum dots (PQDs), particularly the tunable photoluminescence (PL) across the visible spectrum, make them a promising tool for chlorinated detection. However, the correlation between the fluorescence emission shift behavior and the interface of phase transformation in PQDs has not been thoroughly explored. In this study, we synthesized CsPbBr PQDs via the hot-injection method and demonstrated their ability to detect chlorinated volatile compounds such as HCl and NaOCl through a halide exchange process between the PQDs' solid thin film and the chlorinated vapor phase.

Background And Purpose: Prolonged length of stay (LOS) following a stroke is associated with unfavorable clinical outcomes. Factors predicting LOS in medium vessel occlusion (MeVO), impacting up to 40% of acute ischemic stroke (AIS) cases, remain underexplored. This study aims to investigate the predictors of LOS in AIS-MeVO.

Introduction: Enteric pathogens are a leading causes of diarrheal deaths in low-and middle-income countries. The Exposure Assessment of Infections in Rural Ethiopia (EXCAM) project, aims to identify potential sources of bacteria in the genus and, more generally, fecal contamination of infants during the first 1.5 years of life using as indicator.

The first two vaccines administered in the COVID-19 vaccination campaign of India were Covaxin (BBV152) and Covishield (ChAdOx1-nCoV-19). In this study, we evaluate the longevity and sustainability of the humoral immune response after vaccination and various factors influencing it. An observational study was conducted in individuals who received both doses of Covaxin or Covishield vaccine, and their blood samples were analyzed for total-antiRBD-SARS-CoV-2 antibodies.
