This study found a significant shift to the telogen phase in the hair growth of children with classical marasmus compared to normal children, suggesting a connection to the chronicity of the condition.

In this study on mice, intensive stress through methods like resiniferatoxin injections and physical restraint was found to inhibit hair follicle growth, with the mechanism involving the sympathetic nervous system and the cAMP signaling pathway in hair follicle stem cells.

This study observed morphological changes in scalp hair follicles of humans deprived of protein for 15 days, which suggests potential use in diagnosing protein-calorie malnutrition.

This review discusses short anagen syndrome, highlighting its symptom of abnormally short scalp hair without associated systemic diseases, and notes that hair length often improves spontaneously after puberty without treatment.

Lack of protein causes hair root damage, but it can be reversed by eating protein again.

This study found that overexpression of PTHrP in mice chondrocytes led to short-limbed dwarfism and delays in endochondral ossification, highlighting PTHrP's role in inhibiting chondrocyte differentiation.

This report describes two children with congenital hypotrichosis and found their short hair is due to a shortened anagen phase, with the condition resolving spontaneously during puberty.

This case report describes three patients with Netherton syndrome who experienced growth hormone deficiency and improved growth rates following growth hormone therapy.

This study found that specific ATP-competitive TOR inhibitors (asTORis) decrease root growth in Arabidopsis thaliana in a dose-dependent manner, similar to their effects on mammalian cells.

This case report details a 3-year-old girl with short anagen syndrome, characterized by short, sparse hair, where X-ray microanalysis showed her hair's main bioelements were normal.

This article discusses short anagen syndrome, identifying it as a condition with a shorter anagen phase in hair follicles, but reports no new clinical results.

This study reported that stress in early life negatively impacted hair growth in mice at older ages, while Tremella fuciformis Berk extracts partially protected against these effects.

This article reviews the clinicopathologic features of short anagen syndrome in a child and suggests diagnostic methods like clinical examination and scalp hair growth rate measurement, without reporting new clinical results.

This article reviews the normal and delayed maturation of the HPG axis and pubertal development in boys and girls, emphasizing clinical aspects of diagnosing and managing delayed puberty, but it reports no new clinical findings.

This study found that quiescent bulge stem cells, when prevented from contributing to hair follicle and epidermal regeneration, did not affect hair follicle growth or wound healing in the short term.

The researchers reported that silencing the NtNCED3-2 gene in tobacco reduced ABA content and drought tolerance, inhibited root and leaf development, and decreased photosynthetic ability due to altered isoprenoid metabolism.

In this study at King Fahad Hospital's outpatient clinic, researchers found a 44% prevalence of zinc deficiency among 1000 patients, noting a particular concern among women with hair loss and emphasizing the role of dietary factors like phytates that inhibit zinc absorption.

This study reports that the proposed treatment scheme for diffuse and androgenetic hair loss showed high therapeutic efficacy in improving patients' hair condition.

Malnutrition severely harms growth and development in young baboons.

This study found that transdermal DHT treatment increased penile length in boys with 5α-reductase type 2 deficiency, but post-pubertal growth was limited and carried potential prostate complications.

This study found that telomere shortening disrupts BMP/pSmad/P63 signaling, leading to skin atrophy via Follistatin up-regulation, and suggests potential therapeutic targets.

This study found that in wild-type Arabidopsis plants, root hair growth is suppressed with increased nutrient availability, with RHD6 subfamily genes down-regulated and GTL1 and DF1 genes influencing root hair morphology under these conditions.

This study reported that human balding scalp grafted onto nude mice showed reduced linear growth rates of both vellus and terminal hairs.

This study found that conditioned media from SHED stem cells cultured in STK2 media significantly stimulated hair growth in mice more effectively than media from HFSCs.

In this study, phosphorus starvation in Arabidopsis thaliana roots strongly affected stress-induced cytosolic calcium ion modulations, which were reversible with phosphorus resupply.

Monitoring nutrition and health is crucial for the well-being of institutionalized mentally retarded children.

This study found that in mice, chronic stress elevates corticosterone levels, which suppresses hair growth by keeping hair follicles in a prolonged resting phase.

This report describes the second documented case in England of a 14-year-old Asian girl with Rapunzel syndrome, underlining the importance of suspicion to prevent delayed diagnosis in similar patients.

This study found that foot shock stress prolonged the telogen stage and delayed anagen induction in the hair cycle of non-depilated mice, potentially through stress-induced actions of substance P.
