Interventional human ocular safety experiments for 222‐nm far‐ultraviolet‐C lamp irradiation

Photochemistry and Photobiology, Volume 101, Issue 2, Page 517-526, March/April 2025.
To directly assess the ocular safety of 222‐nm far‐ultraviolet‐C (UVC) irradiation in humans, five subjects were exposed to 222‐nm UVC at doses of 22, 50, and 75 mJ/cm2. The findings indicate that far‐UVC irradiation does not cause “clinically significant photokeratitis” or long‐term ocular damage, though it may induce temporary discomfort.

Human ocular‐discomfort‐free thresholds for 222 nm Far‐UVC irradiation: A prospective interventional study

Photochemistry and Photobiology, EarlyView.
Eye discomfort induced by 222 nm far‐UVC irradiation is significantly correlated with both irradiance and radiant exposure dose. The red circles indicate conditions with significant differences in the number of eye discomfort compared to the control group (blue circles), while the green circles indicate conditions with no difference from the control ...

The oral microbiota and periodontal health in orthodontic patients

Periodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.

Chemical agents to control biofilm formation in step 1 of care—Toothpastes and mouthwashes/concepts and challenges

Periodontology 2000, EarlyView.
Abstract Maintaining optimal oral hygiene is important for overall oral care, ensuring the well‐being of teeth and their surrounding tissues. In addition, it promotes fresh breath and a pleasing smile. A key element of oral self‐care is the daily use of toothpaste during regular brushing.

Population level data on aging in periodontal and peri‐implant health—Aging is not a contraindication for periodontal or peri‐implant therapy

Periodontology 2000, EarlyView.
Abstract Objectives Global population aging is leading to a greater retention of natural teeth into later life and an increasing prevalence of dental implant therapy. Although advanced age has traditionally been regarded as a risk factor for compromised outcomes, population level evidence remains lacking.

Understanding exosomes in facial esthetics and skin aging

Periodontology 2000, EarlyView.
Abstract Background Skin aging is a multifactorial process mediated by intrinsic (genetic and metabolic) and extrinsic (environmental) factors leading to functional and structural deterioration, including wrinkles, loss of collagen and elastin, as well as various pigmentation disorders.

Understanding Exosomes in Hair Regeneration

Periodontology 2000, EarlyView.
Abstract Background Alopecia is a prevalent condition correlated with significant psychosocial challenges, while contemporary treatments exhibit variable efficacy, require extended use, and may cause adverse effects. This review aimed to comprehensively assess exosome‐mediated interventions as a novel cell‐free regenerative approach for hair ...

A Randomised Placebo‐Controlled Study to Evaluate the Efficacy and Safety of a Two‐Dose Topical Terbinafine and Betamethasone Gel for the Treatment of Yeast (Malassezia pachydermatis) Otitis Externa in Dogs

Veterinary Dermatology, EarlyView.
Background: Otitis externa (OE) with Malassezia pachydermatis overgrowth with limited bacterial involvement is common in dogs. Treatment with products containing antibiotics is unnecessary and not consistent with judicious use of antimicrobials.

Mucosal‐Associated Invariant T Cells in Health and Disease

MedComm, Volume 7, Issue 10, October 2026.
The roles of MAIT cells in health and disease and their therapeutic applications. In healthy individuals, riboflavin metabolites secreted by commensal bacteria at mucosal sites are presented by MR1, leading to the activation of MAIT cells. Activated MAIT cells can maintain the barrier integrity of mucosal tissues in a steady state or migrate to the ...

Untreated Hair Dye Effluents Enter the Environment: Are They a Threat to Human Health?

Environmental Toxicology, Volume 41, Issue 10, Page 998-1010, October 2026.
ABSTRACT The effluents generated during the process of hair dyeing exhibit a complex composition, comprising chemical compounds with varying toxicity levels. While the adverse impact of hair dyes on human health is acknowledged, there is a notable absence of studies addressing the toxicity associated with effluents produced during these activities. The
