This study aimed to define the smoking status and smoke-related gingival melanin pigmentation in army recruitments and was conducted with army recruitments in Sivas. Nine hundred eight subjects were examined. The oral and dental health of those subjects was checked and recorded. The smoking status of the subjects was self-reported and recorded on questionnaires by researchers. The chi2 test and Kruskal-Wallis test were used for statistical analysis. More than one-half of the subjects (54.3%) were primary school graduates and the mean age was 20.2 +/- 0.95 years. The response rate regarding smoking was 100%. Of the respondents, 596 (65.7%) were current smokers, 12 (1.3%) were former smokers, and 300 (33.0%) were never smokers. The gingival melanin pigmentation rate was 27.5% in current smokers and 8.6% in those who never smoked (p = 0.000). Smoking five to nine cigarettes a day appeared to be sufficient to cause gingival melanin pigmentation. The proportion of smokers who had melanin pigmentation did not change after 10 cigarettes a day. A rehabilitation project on smoking prevention and smoking cessation for army recruitments is urgently needed.

Background: Post-inflammatory hyperpigmentation (PIH) is a common cosmetic concern, often leading to significant psychological distress for the patients. With the widespread application of lasers including ablative fractional resurfacing (AFR) with a 10,600 nm CO laser, PIH caused by lasers is becoming increasingly common. But due to the absence of an appropriate animal research model, our understanding of pathophysiological mechanisms and preventive strategies for PIH remains limited.

Background: Plumage coloration is a distinctive trait in ducks, and the Liancheng duck, characterized by its white plumage and black beak and webbed feet, serves as an excellent subject for such studies. However, academic comprehension of the genetic mechanisms underlying duck plumage coloration remains limited. To this end, the Liancheng duck genome (GCA_039998735.

Bladder melanosis is a rare and poorly understood condition involving melanin pigmentation within the urothelial mucosa. Cases often present with haematuria, urinary obstructive symptoms, or cystitis. While generally considered benign, its potential association with malignancy warrants regular monitoring, as cases have previously been reported of an association with urothelial carcinoma and melanoma, although it is unclear whether there is a causal relationship.

Gingival depigmentation with the help of lasers is known as an effective technique. The aim of this study was to compare the efficiency of 980nm diode and CO2 lasers in the treatment of gingival hyperpigmentation. In this clinical trial study, 14 individuals (8 females and 6 males) with the age range of 19 to 47 years were selected.

Imatinib mesylate is a targeted anti-cancer drug with skin pigmentation as a side effect. The action mechanism of imatinib mesylate on melanogenesis remains unclear. The purpose of this study was to elucidate the mechanism of imatinib mesylate on melanogenesis associated with the microphthalmia-associated transcription factor (MITF) signaling pathway in murine melanoma cells.
