In this study, repeated finasteride administration was associated with decreased social interaction and cognitive deficits in male rats, potentially linked to changes in cholinergic system activity.

This review examines the potential role of odorant receptors in human skin cells responding to flavor compounds and their implications for skin health and disease, without providing new clinical results.

This study suggests that aroma oils categorized by scalp type have similar chemical compositions, potentially enhancing their effectiveness in aromatherapy for scalp issues.

This study observed that electrical stimulation of specific mechanoreceptive afferents in the orofacial region can evoke sensations consistent with their response properties, while others may require multiple afferents to access perceptual levels.

In this study, nucleotide sequence variation in the KRTAP13-3 gene was associated with changes in heterotypic hair fibre diameter variation in Chinese Tan sheep.

This study examined the unique structural features of sinus hair follicles in the shrew Sorex unguiculatus, which suggest a specialization for vibration sensing.

This paper highlights the emerging trend of treating androgenic alopecia with botulinum toxin, despite insufficient scientific evidence supporting its effectiveness.

This study observed that using an aroma shampoo containing essential oils for 4 weeks improved hair density and number in the occipital area, unlike a general shampoo used by the control group, which led to decreased hair number and thickness in the parietal area.

This study found that harp seal vibrissal innervation studies focusing only on lateral vibrissae may overestimate total innervation by about 20%, highlighting the importance of considering the entire snout.

In this study, researchers used synchrotron X-ray imaging to examine rat vibrissa follicles, finding that despite variations in vibrissa length and follicle size, certain sensory structures remain consistent, suggesting specialized roles in sensory processing depending on the vibrissa type.

Rat hair follicle stem cells have functional oxytocin receptors, useful for studying neuropsychiatric disorders.

The researchers reported that lavender shampoo activated alpha brain waves, suggesting calming and memory effects, while geranium shampoo enhanced arousal and memory by stimulating brain waves in the laryngeal lobe.

Using synchrotron X-ray imaging, this study mapped the complex innervation of male rat vibrissa follicles, revealing distinct types of myelinated afferent neurons and patterns of axonal organization that may inform sensory processing in the brainstem.

This study reports that oxytocin receptor expression in keratinocytes shows a potential relationship with touch sensory neurons, suggesting a role in skin sensitivity and the broader function of sensory neurons.

In this study, researchers observed that aroma oil-enhanced scalp scaling significantly improved scalp conditions over 8 weeks, marked by increased water and oil content, reduced keratin and surface value, and higher satisfaction in hair-related outcomes compared to the control group.

This study, involving an international panel of 16 psychodermatology experts, proposed a new classification system for psychodermatology disorders that aims to unify previous classifications and improve their management by systematizing disorders into two main categories: primary mental health disorders and primary skin disorders.

This review synthesizes the diverse roles of the transcription factor LHX2 in development, tissue maintenance, and injury repair across various organ systems, highlighting its potential therapeutic applications and significance in regenerative medicine, particularly in developmental disorders and tissue regeneration.

Aptamers can improve wound healing and promote hair growth.

Crickets have genetically controlled hair plates that help them sense and move their antennae.

This article reviews the use of sodium fluoride in otosclerosis management, finding limited evidence of its efficacy in preventing hearing deterioration and highlighting potential toxicity concerns.

This study described the diverse vibrissal follicle anatomy in fetuses of three cetacean species and observed species-specific differences, supporting further investigation into vibrissal form and function across cetaceans.

This article proposes naming the visual identification of androgenic alopecia in COVID-19 patients as the "Gabrin sign" to indicate higher risk for severe symptoms, but reports no new clinical results.

Fungi-produced compounds can change plant root growth.

In this study, researchers found that human scalp hair, particularly when unwashed, can significantly react with ozone, reducing personal ozone exposure and increasing exposure to volatile reaction products.

This study reports that the differential expression patterns of three retinaldehyde dehydrogenases suggest a regulated need for retinoic acid synthesis in various organs during late mouse organogenesis.

This study found that VDR knockout mice exhibited muscle and motor impairments affecting locomotor behavior, while cognitive functions such as exploration, working memory, and anxiety appeared unaffected.

This review discusses the role of the endocannabinoid system in skin health and disease, highlighting its potential for future research and applications, but reports no new experimental results.

This chapter reviews the potential role of gonadal hormones in sex differences in play and spatial behavior, noting a lack of conclusive evidence but suggesting perinatal androgen exposure might contribute to observed differences. It reports no new research results.
