This study found that while a tip-focused calcium gradient influences localized growth in root hairs and pollen tubes, it is not the primary determinant of growth direction in root hairs of Arabidopsis thaliana.

This study suggests that a tip-focused gradient of intracellular G-actin concentration at the apex is crucial for root hair growth, and maintaining this gradient requires high calcium levels at the root hair tips.

This article presents a practical tip to enhance the efficiency of follicular unit transplant hair restoration surgery, a procedure known for being effective yet time-consuming and laborious.

This essay discusses the role of the nail in mammalian digit tip regeneration and explores whether nail stem cells are solely responsible for this regenerative ability, with no new results presented.

This research describes three neonatal cases of nasal tip injuries resembling hypoxic damage, which healed with significant scarring, and calls for further investigation into the condition's causes and treatment.

This study found that salinity stress in Arabidopsis thaliana root hairs may inhibit hair extension through changes in the tip-focused Ca(2+) gradient, while cytosolic pH remains unaffected.

The researchers reported that in Arabidopsis collet hairs, nuclear positioning near the cell tip is not essential for hair growth, although it correlates with growth dynamics.

This study observed that while calcium influx does not initiate root hairs in Arabidopsis thaliana, it may be crucial for sustaining their elongation through elevated calcium levels at the root hair tip.

This study developed a sensitive method to precisely determine hair lipid composition, demonstrating specific lipid changes from the root to the tip in untreated hair fibers from two women.

This study reports a case of dermatophytosis in an 11-month-old spayed female dog, which exhibited alopecia in the neck and ear tip regions, a condition common in tropical and temperate climates and caused by fungi affecting both animals and humans.

This case report describes a dog suffering from dermatophytosis, a zoonotic fungal infection common in warm and humid climates, with alopecia noted in the neck region and the tip of the ear.

This report describes a case of dermatophytosis, a zoonotic fungal infection common in tropical and temperate climates, affecting a female dog with alopecia on its neck and ear tip.

This thesis explores the role of the actin cytoskeleton in plant cell growth, highlighting its involvement in signal transduction and the regulation of tip growth in cells like root hairs.

This paper discusses the cellular and molecular processes involved in root hair growth in higher plants, focusing on cytological phenomena and the effects of growth regulators and mutations, but reports no new experimental findings.

This study found that the signaling peptide CLE40 and receptor proteins CLV2 and CRN regulate root meristem differentiation through two distinct, antagonistic pathways activated by CLE40 in a dose-dependent manner.

This study reported that a single treatment with a short-pulsed 755-nm alexandrite laser effectively treated trichostasis spinulosa in patients with skin types II to V, providing rapid results with minimal pain and no recurrence during a 3-month follow-up.

This study found that homocysteine-keratin accumulation in human hair increases towards the tips, linked to copper/iron-catalyzed demethylation of methionine, and may contribute to keratin damage.

This study reports an abnormal onion-shaped swelling on the hair shafts of some Abyssinian cats, affecting the appearance of their coat, though skin and hair structures appear normal under the microscope.

This review outlines the current understanding of how pH contributes to root hair development and reports no new experimental findings.

In this study, researchers observed that during zebrafish fin regeneration, osteoblast Erk activity, influenced by Fgf receptor signaling, forms gradients scaling with amputation length, which predicts regenerative tissue growth and skeletal structure size.

This study found that the medulla of Japanese hair contains unsaturated lipids such as squalene and oleic acid, which may contribute to hair glossiness.

This article discusses central trichoptilosis with onycholysis but provides no new clinical results.

This study found that nuclear androgen receptor expression was enhanced by dihydrotestosterone in rat gubernacular mesenchyme, but this did not affect muscle morphology or matrix composition during fetal development.

This case report details a French bulldog with congenital alopecia, featuring reduced hair follicles and epidermal abnormalities, which are typical of the condition.

In this study, forming inclusion complexes of Finasteride and poly (ethylene glycol) resulted in significantly improved solubility and dissolution rates, suggesting a promising new solid form for enhanced drug release.

This study concluded that a triangular flag-shaped incision design in hair transplantation achieved better hair alignment compared to the common elliptical incision, particularly in patients with specific hair directions.

This study found that a positive feedback loop involving RHD2, reactive oxygen species, and calcium ions helps maintain root hair growth sites and influences cell shape in Arabidopsis thaliana.

This review highlights the role of reactive oxygen species in root hair growth and cell expansion in plants but does not report new empirical findings.

This review discusses mammalian models of epimorphic regeneration to define a vertebrate regeneration blastema, concluding that regenerative failure likely stems from cellular responses to the microenvironment after injury, not progenitor cell availability, and calls for targeted modification studies in mammals to advance human regeneration.

This study found that magnesium supply significantly influences root hair development in Arabidopsis, affecting reactive oxygen species, calcium signaling, and the expression of genes associated with root hair growth.
