The aggressive face of melasma: unveiling the influence of upper lip pigmentation on social perception.

Introduction: Although melasma leads to emotional distress and quality-of-life reduction, indigenous cultures practice female facial tattooing. Facial cues influence personality trait inferences and attractiveness ratings. Skin lesions have been shown to alter gaze patterns, emotion perception, and social evaluations.

Anatomical variants of acne differ in their impact on social perception.

Background: Acne negatively affects quality of life, however quality-of-life scores poorly correlate with disease severity scores. Previous research demonstrated existence of facial areas in which skin lesions have greater impact on gaze patterns. Therefore, we hypothesized that anatomical variants of acne may be perceived differently.

Perceptive Hierarchy of Facial Skin Lesions: An Eye-tracking Study.

Equal importance is given to every skin lesion in treatment guidelines and severity grading systems for facial lesions. Face recognition studies suggest differentially perceived areas of the human face. The aims of this study were to quantify the visual attention given to facial skin lesions and to explore their hierarchy.

The Dynamics of Changes in the Concentration of IgG against the S1 Subunit in Polish Healthcare Workers in the Period from 1 to 12 Months after Injection, Including Four COVID-19 Vaccines.

Background: The presented research made it possible to obtain the characteristics of changes in anti-SARS-CoV-2 IgG within one year of vaccination in healthcare workers.

Materials And Methods: The research group consisted of 18,610 participants represented by medical and administration staff. IgG antibody concentrations were determined by ELISA.

Anti-SARS-CoV-2 IgG against the S Protein: A Comparison of BNT162b2, mRNA-1273, ChAdOx1 nCoV-2019 and Ad26.COV2.S Vaccines.

Background: COVID-19 vaccines induce a differentiated humoral and cellular response, and one of the comparable parameters of the vaccine response is the determination of IgG antibodies.

Materials And Methods: Concentrations of IgG anti-SARS-CoV-2 antibodies were analyzed at three time points (at the beginning of May, at the end of June and at the end of September). Serum samples were obtained from 954 employees of the Nicolaus Copernicus University in Toruń (a total of three samples each were obtained from 511 vaccinated participants).

Influence of the Spectral Quality of Light on Daytime Alertness Levels in Humans.

Exposure to light is very important for human health. However, the characteristics of the light stimulus and the appropriate timing of such exposure are essential. Studies that have used monochromatic light exposure have shown no systematic patterns for the effects of blue light compared to longer wavelengths.
