Aim: This study aimed to compare the validity and reliability of polarized and non-polarized intraoral photography for the measurement of gingival melanin pigmentation.
Materials And Methods: A case series study was conducted on ten patients scheduled for gingival depigmentation. A total of 976 polarized and non-polarized image samples were collected, capturing two rows above the gingival margin, for analysis. These images were taken both before and one year after the depigmentation procedure. Three independent evaluators assessed the photographs (an orthodontist, a general dentist, and a layperson). The Dummett Oral Pigmentation Index (DOPI) and Gingival Melanosis Record (GMR) indices were used to measure the level of gingival pigmentation.
Results: The study found no significant differences between polarized and non-polarized images taken before and after depigmentation. Both methods of imaging received similar scores from the evaluators. The orthodontist identified more pigmented slides than the layperson and the general dentist.
Conclusion: Both polarized and non-polarized photographic methods may be used for assessing gingival pigmentation. However, further research is warranted to confirm this finding and examine additional factors.

Human nasal epithelium (HNE) organoid models of SARS-CoV-2 infection were adopted globally during the COVID-19 pandemic once it was recognized that the Vero cell line commonly used by virologists did not recapitulate human infection. However, the widespread use of HNE organoid infection models was hindered by the high cost of media and consumables, and the inherent limitation of basal cells as a scalable continuous source of cells. The human Calu-3 cell line, generated from a lung adenocarcinoma, was shown to largely recapitulate infection of the human epithelium and to preserve the SARS-CoV-2 genomic fidelity.

Objective: This study aimed to systematically investigate whether polarized or non-polarized training leads to greater physiological and performance adaptations in cyclists.
Design: A systematic review and meta-analysis were conducted, focusing on interventions categorized as polarized, non-polarized, or unclear. Inclusion criteria required participants to be at least recreationally trained cyclists (VO ≥ 59 ml/kg/min) and interventions lasting > 4 weeks.

Optical information encryption technology has garnered significant attention in currency security, information protection, and personal identification. While optical metasurfaces are considered ideal platforms for information encryption, their high cost and time-intensive fabrication processes have limited their widespread applications. To address this, emergent chiroptical nanomaterials offer new opportunities for information encryption through their polarization capabilities.

One of the features of the model is its ability to predict the results of a photochemical polishing process without the need for time-consuming calculations. The proposed model analyzes the characteristics of the surface evolution during polishing based on the initial roughness parameters and the polarization of the incident radiation.

Membrane proteins are sorted to the plasma membrane via Golgi-dependent trafficking. However, our recent studies challenged the essentiality of Golgi in the biogenesis of specific transporters. Here, we investigate the trafficking mechanisms of membrane proteins by following the localization of the polarized R-SNARE SynA versus the non-polarized transporter UapA, synchronously co-expressed in wild-type or isogenic genetic backgrounds repressible for conventional cargo secretion.
