This study explains surgical techniques for hair transplantation using the sharp implanter method, emphasizing 11 key principles that optimize efficiency and precision, and reports high graft survival and natural hair density when these principles are followed.

This study observed that boxer and labrador dogs showed seasonal variations in hair follicle cycles linked to temperature and photoperiod, differing from schnauzers.

This study observed that in frizzled 6 null mice, initially uncorrelated hair follicle orientations develop into highly ordered patterns over time, suggesting possible mechanisms for biological structure patterning.

This study found that combining second-harmonic generation with optical coherence tomography may effectively evaluate wound healing by monitoring collagen formation and optical signal changes in regenerated tissue.

This report describes a unique anatomical case featuring a detailed formation of a periaortic venous ring in an organic sample.

In this study, researchers evaluated the binding of keratin-associated proteins and α-keratins to human hair fibers, finding that chemical preactivation significantly enhanced binding to natural hair, while perming altered binding characteristics and increased penetration depth.

In this study, researchers observed that telogen hair was more prevalent than anagen hair in both male and female agoutis over a one-year period in Teresina-PI, regardless of dry or rainy seasons, with no significant differences in dermal follicular volume between the sexes.

This study concluded that combining vertical and transverse sections of scalp biopsy specimens improves diagnostic yield for certain hair disorders without increasing costs.

This study found that significant hair loss in about one-third of patients after vertical gastroplasty was reversed by zinc supplementation.

This study found that vertical sections of alopecia biopsy specimens had a higher concordance rate with the original combined diagnosis compared to transverse sections alone, although both methods have their pros and cons.

This article provides departmental contact information for Dr. Dirk M. Elston at the Geisinger Medical Center and reports no research findings.

This study suggests that for single biopsy specimens, transverse sections may be preferable for diagnosing noncicatricial alopecia, while vertical sections may be better for suspected lichen planopilaris.

This study reports that horizontal sections of scalp biopsies improve the diagnosis of alopecia areata, especially when characteristic inflammatory infiltrates are missing.

This study found that vertical sleeve gastrectomy improved metabolic, behavioral, and reproductive symptoms in a rat model of PCOS, suggesting it may be a potential therapy for specific aspects of PCOS.

In this study, transverse sectioning of scalp biopsy samples showed higher diagnostic accuracy than vertical sectioning for noncicatricial alopecia, although both techniques are important for accurate diagnosis.

This article discusses ideal techniques for harvesting donor tissue in hair restoration surgery but reports no new clinical results.

This study conducted in a hair restoration clinic found that using the vertical scalp mobility method resulted in a significantly greater number of hairs available from the donor strip compared to the horizontal method, with an increase of approximately 970 hairs (P < .05).

Transverse sections are better for non-scarring hair loss, vertical sections are better for lichen planopilaris, and either method works for other scarring hair loss types.

Finasteride may cause gum side effects in some patients.

This study found that scalp involvement in dermatomyositis consistently shows a nonscarring pattern with chronic telogen effluvium, featuring telangiectasia and mucin deposition as universal histologic markers.

This study found that serial vertical sectioning of scalp biopsies significantly increases the histological diagnostic yield for alopecias.

This dissertation reports three findings: vertical mergers can facilitate downstream collusion, advertising for new products may follow an inverted U shape, and incumbents might obscure the quality signals of uncertain new market entrants.

This study found that hair diameter varies significantly within the occipital safe donor area, with thicker hair in the upper sections and thinner hair in the lower sections.

In this study, researchers identified an autosomal dominant mutation (E402K) in exon 7 of the KRT86 gene as a cause of Monilethrix in a large family from Turkey.

This report details a case of right fourth nerve palsy in a 47-year-old man following hair replacement surgery, hypothesized to be due to brainstem instability related to an anatomical variant and postoperative posture-induced cerebrospinal fluid shifts.

Goat hair shows changes in metal levels and stress when goats move from indoors to mountain pastures.

This study concluded that horizontal sections of scalp biopsy specimens provide more diagnostic information for male pattern androgenetic alopecia than vertical sections and can predict hair regrowth potential following topical minoxidil therapy.

This study introduces the "HoVert" technique, which generates both vertical and horizontal sections from a single biopsy to effectively differentiate lichen planopilaris from discoid lupus erythematosus in alopecia cases.

This study found decreased hair density and altered follicular architecture in the balding frontal scalp of patients with androgenic alopecia, with increased vellus hairs noted.

This study reported that dilated follicular infundibula are a highly useful histopathologic criterion for diagnosing alopecia areata, particularly during its recovery stage.
