In this study, researchers propose that different vertebrate skin appendages, such as hair, feathers, and scales, evolved in parallel from a shared ancestral cell structure associated with teeth, dating back approximately 420 million years ago.

This study describes the stages of hair follicle development and foetal pelage growth in southern elephant seals, highlighting the formation and shedding processes of the first and subsequent hair generations.

This study described the structure of the hair brush on male Endoclita vietnamensis moths' legs, identifying characteristics such as specialized scales and a pheromone gland, which could facilitate the future development of pheromone-based pest control methods for eucalyptus pests in China.

This study explored the molecular biology of skin adaptations in pangolins, revealing that certain genes for lipid synthesis have inactive patterns, while others related to skin function remain intact, suggesting complex evolutionary changes in their skin physiology.

Keratin gene clusters in humans and marsupials are similarly organized.

The researchers reported a case of a neotropical porcupine co-infected with Brazilian porcupine poxvirus and Toxoplasma gondii, suggesting the need for further investigation into the impact of this interaction.

This perspective highlights the potential of reptile integument as an experimental model to understand the evolution of amniote skin structures, but reports no new research findings.

This review provides an overview of the molecular evolution of corneous beta-proteins in reptiles and birds, highlighting their distinct genetic origin and role in epidermal structures, but reports no new results.

This article discusses how dermoscopy, particularly "entomodermoscopy," aids in diagnosing skin infestations and infectious dermatoses, enhancing clinical evaluations, and monitoring treatment efficacy for conditions like scabies, pediculosis, myiasis, and tungiasis.

This study suggests that Demodex mites might universally inhabit adult humans, with a phylogenetic analysis indicating potential undiscovered lineages of the D. brevis species based on geographic differences.

This study demonstrates a varied distribution of keratins in the epidermis of the Malayan pangolin, suggesting evolutionary adaptations related to their distinctive scales.

This case report highlights the simultaneous presence of white piedra, identified as T. inkin, and pediculosis capitis in one patient to emphasize their clinical distinctions.

This study proposes that seasonal alopecia and reproductive changes in six female fossas at the San Diego Zoo may be linked to hormonal changes associated with reproductive activity.

This study found that Hopx labels a long-lived progenitor population in hair follicles, which contributes to hair follicle stem cell homeostasis and has an alternative origin from previously thought progenitors.

This review highlights the regenerative abilities of *Xenopus laevis*, focusing on how tadpoles regrow complex tail structures and the cellular and molecular mechanisms behind this. It underscores *X. laevis* as a valuable model for understanding regeneration, with insights potentially advancing regenerative medicine.

This study reported a new method enabling the observation of the full leg regeneration process in the crustacean *Parhyale hawaiensis* over 10 days, capturing cellular resolution while minimizing photodamage, through innovative imaging techniques and computer-assisted cell tracking.

This study suggests that mouse lineage specification during pre-implantation development involves distinct timing and mechanisms for trophectoderm and inner cell mass differentiation, challenging existing models.

This study reported intra-familial transmission of Arthroderma benhamiae among Canadian porcupines in a Japanese zoo, with genetic sequences previously undocumented in Japan or the GenBank database.

This study reports that KRTAP-like proteins, which resemble keratin-associated proteins found in mammals, are also present in the cornified teeth of various lamprey species, suggesting these proteins may serve similar functions in skin appendages across different vertebrates despite independent evolutionary origins.

This case report identified cutaneous epitheliotropic T-cell lymphoma in a 3-year-old male sugar glider after skin biopsies, highlighting the need for thorough diagnostic evaluations in exotic pets.

Only Deomyinae rodents can regenerate complex tissues.

This study reported that 39.7% of Amargosa voles had mite-associated lesions, which may severely impact their health and fitness.

Terrestrial vertebrates have balanced keratin gene clusters, unlike teleost fish.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

In this study, the researchers reported extensive gene loss and high pseudogenization rates of α-keratin genes in cetaceans compared to terrestrial mammals, likely linked to hair loss and aquatic adaptations.

In a case study, a 6-year-old Shih Tzu with both demodicosis and babesiosis showed improvement after treatment, which included medications like ivermectin and supportive care such as specialized shampoos and environmental spraying, evaluated up to the 21st day.
