This review discusses the progress in identifying stem cells responsible for tissue regeneration and highlights technological advances in tracking their behavior, but reports no new clinical results.

Polarized microscopy is a quick and free method to correctly identify types of hair loss.

This case report describes a 3-year-old male with X-linked ichthyosis and associated neurologic abnormalities, identifying an unusual cortical development malformation and suggesting that abnormal hair banding may assist diagnosis.

This study found that the yellow dot pattern observed in dermoscopy of alopecia areata corresponds to inefficient follicular structures containing hair remnants, as corroborated by reflectance confocal microscopy and pathological findings.

This review discusses the role of hair microscopy in diagnosing alopecia, stating that while it excludes diagnoses related to hair breakage, it only confirms nonspecific short anagen in alopecia cases.

Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.

This study introduced a new adaptive microrhizotron for non-destructive observation of pepper root traits, finding that specific installation patterns significantly enhanced root interception probability while effectively measuring root architecture for plant research.

This study found that scanning electron microscopy can identify four specific hair morphology patterns in alopecia areata patients, offering a less invasive diagnostic option compared to punch biopsy.

This study examined the microscopic characteristics of hair or feather in five animal drug components of the Shenrongbian pill, identifying distinctive medulla cell shapes and hair cuticle patterns for each component.

This paper discusses the use of Digital Volumetric Imaging with fluorescent dyes to visualize and compare the interior structures of six different virgin hair types, reporting no new clinical results.

This study found that using a microscope can effectively distinguish between human and animal hair based on microscopic characteristics, making it a critical tool in forensic investigations.

This study concludes that elastic tissue staining is the most reliable method for identifying scarring patterns in alopecia biopsy specimens, and polarized microscopy may provide specific insights for nonscarring alopecia.

This study documented that dermatophytosis was highly prevalent in Basra's cats, particularly affecting males and cats under nine months, with lesions most frequent on ears, face, and abdomen.

This study found that microfibrils play a crucial role in shaping permanent waves by thioglycolic acid, and treating damaged hair with hydrolyzed keratin improved both waving efficiency and hair damage.

This study found that epithelial components of calcifying epithelioma of Malherbe showed lectin binding and keratin staining patterns similar to normal hair follicles, with prominent Con A staining in tumor giant cells.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

This review discusses the development and application of multiphoton microscopy in dermatology, highlighting its advantages and potential future research directions without reporting new clinical results.

This case study describes a 14-year-old girl with pili annulati who had fragile hair, which may be due to cavities within the hair shafts as seen in electron microscopic examinations.

This study reports that Elvitegravir, a drug currently approved for other uses, shows potential as a neuro- and mitoprotective agent by attenuating mitochondrial damage caused by NMDA receptors in primary mouse cortical neurons.

This study undertook powder microscopy and preliminary phytochemical analysis of Buxus wallichiana's stem bark and leaves, identifying steroids, alkaloids, saponins, and glycosides without reporting clinical outcomes.

This review provides guidance on using two-photon microscopy for real-time and long-term visualization of stem cell activity in live mice skin, focusing on its application in researching skin and stem cell biology.

This study used in vivo confocal microscopy and a ResNet34 deep learning model to classify meibomian gland images with an AUROC greater than 0.95, indicating its potential for automatic diagnosis and screening of meibomian gland dysfunction.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.

This study reports that generalized discoid lupus erythematosus is a recognized canine variant of cutaneous lupus erythematosus, resembling its human counterpart, with varied treatment responses and common relapses.

Hair transplant complications were likely due to deep graft placement and rough handling.

This study proposes an innovative treatment for stretch marks by combining skinbooster and microneedling techniques, which induce tissue remodeling and collagen synthesis, and suggests using confocal microscopy as a valuable tool for monitoring skin changes in aesthetic dermatology.

Among maize plants, this study observed that root hairs tend to grow in air-filled pores at the root-soil interface, but their growth into the soil matrix is limited, posing potential constraints on nutrient uptake, anchorage, and rhizosheath formation.

This study found that hair transplantation using the follicular unit extraction method significantly improved hair density and patient satisfaction in males with androgenetic alopecia, especially those younger than 33 and with less severe hair loss.

This study investigated the tensile response and morphological changes of different ethnic hair types using AFM, showing variations between virgin, chemically damaged, and conditioner-treated Caucasian hair under different conditions.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.
