In this study, cyclic ADP-ribose (cADPR) treatment in human hair follicle dermal papilla cells was associated with increased intracellular calcium retention and activated anagen-related signaling without causing significant cytotoxicity, indicating its potential impact on hair growth processes.

In this study, researchers identified a three-step process underlying age-related curved hair from cyclical extension: surface lipid transfer, specific disulfide bond cleavage, and unraveling of α-helices into β-structures, which may inform care strategies to manage hair curvature.

This paper discusses the ongoing debate around megasession hair restoration surgery techniques and notes the standard practice of performing procedures with approximately 600 grafts, but it reports no specific clinical outcomes.

This study explored the diversity of melanocyte stem cell subpopulations in the hair follicles of adult female mice and identified novel groups with distinct immune privilege regulation, suggesting a heterogeneous landscape that future research should consider.

This study found that treatment with the synbiotic SIM01 significantly alleviated multiple symptoms of post-acute COVID-19 syndrome compared to placebo, suggesting potential management benefits through gut microbiome modulation.

This study mapped a detailed genetic profile of goat hair follicle apoptosis, identifying key genes and regulatory factors involved in the hair cycle, offering new insights into programmed cell death.

This review discusses immunohistological and immunofluorescent methods for studying the human hair follicle cell cycle, reporting no new results, and suggests its potential for advancing cell cycle research.

This study identified 2884 long non-coding RNAs (lncRNAs) associated with hair follicle cycling in yaks and highlighted sequence conservation with cashmere goats, suggesting potential pathways for hair growth regulation.

This study used cashmere goats to reveal distinct intermediate states of dermal papilla cells, each with specific roles in hair growth, shedding, and regeneration.

This study developed a new method for analyzing multivariate time-series data that successfully predicts website competition dynamics and outperforms conventional methods in identifying and predicting competitive structures.

This study introduced a new computational method for simulating vibrational frequencies, finding that the multi-molecular fragment model showed the best agreement with experimental data for Finasteride, Lamivudine, and Repaglinide, outperforming traditional models in accuracy.

This study used a 3D live imaging system to map cell dynamics in human hair follicles, revealing patterns of cell movement and division that help explain hair fiber extrusion during hair growth.

Telogen effluvium is hair loss caused by disruption of the normal hair cycle.

This study found that CNGC 6, CNGC 9, and CNGC 14 are crucial for maintaining calcium oscillations necessary for normal root hair growth in plants, with mutations leading to defects like swelling and bursting.

In the Ovulation and Menstruation Health Pilot Study, multimodal recruitment strategies effectively increased racial diversity and survey completion rates for studying menstrual disorders like PCOS.

This review examines the molecular mechanisms of the circadian clock and its effects on cardiovascular functions, proposing a novel non-invasive method using hair follicle cells to assess circadian regulation in humans, but reports no new clinical results.

This study observed that testosterone combined with hormonal contraceptives elevated hormones like estrone and testosterone, altered coagulation factors, and increased sexual behavior frequency in female capuchin monkeys.

In this case study, the researchers reported a rare incidence of bilateral hyperpigmented macules on a patient's lower legs, possibly due to cyclophosphamide, suggesting that this chemotherapy drug may directly stimulate hair follicles to cause skin discoloration.

In this animal study, topical diazoxide treatment led to increased hair thickness and follicle growth in bald stumptailed macaques without causing notable systemic side effects.

This study developed an advanced HPLC-ESI-ion trap MS(n) method for the structural identification of cyclosporin A analogs CyA and CyC and reported the first MS(n)-aided identification of a new CyA analog.

This study demonstrated that the Turing bifurcation, typically a pitchfork bifurcation under zero-flux conditions, becomes transcritical under fixed boundary conditions, highlighting the importance of considering boundary condition variations in morphogenetic analyses.

Mice with extra sheep genes had hair that fell out and regrew in cycles.

In this study, researchers found that coordinated intercellular Ca2+ signaling among basal stem cells in mice is crucial for cell cycle progression and tissue-wide communication during epidermal regeneration.

This study suggests that D2O increases hair length in nude mice by extending the hair cycle duration, particularly the hair-existing phase, which is associated with increased mast cell density.

This review discusses the genetic and molecular factors involved in human hair follicle development and cycling, highlighting identified genes and pathways associated with hair diseases but reports no new results.

This study identified and described a new form of alopecia termed "macular alopecia," predominantly affecting young Hispanic/Latinx females, characterized by small macules on the scalp with a high rate (63%) of spontaneous resolution in about five months.

This review discusses how stem and progenitor cells communicate to synchronize their differentiation responses, highlighting the challenges in identifying these mechanisms and surveying new technologies that may overcome these obstacles.

In this study, researchers found that cyclophosphamide treatment unexpectedly reduced splenic melanin deposition in a murine model, whereas this effect was down-regulated more by the normal and dystrophic catagen phase of the hair cycle.

Hair growth and pigmentation in mice involve specific stages crucial for research.

This study found that mechanical skin stretching can stimulate hair stem cell proliferation and hair regeneration by activating a complex pathway involving WNT, BMP-2, and M2 macrophages.
