This review discusses recent advancements in the development and use of polymer-based nanohydrogels for topical drug delivery, noting their potential to enhance drug loading, release control, and skin penetration for treating dermatological conditions.

In this study, 32 healthy adults with hair fall complaints applied a hair serum daily for 60 days, resulting in statistically significant improvements in hair growth rate, thickness, and density, without any reported adverse events.

This study found that an ethanolic extract of Ganoderma lucidum, especially at 15mg/kg, may promote hair growth in a rat model of testosterone-induced alopecia, showing effects comparable to minoxidil.

This study found that a specific combination of plant growth regulators effectively enhanced in vitro propagation and rooting of Eclipta alba, potentially enabling commercial-scale plant production.

This study found that septoplasty simulation in rats led to decreased exploratory behavior and anxiety, suggesting a link between postoperative stress and changes in the hippocampal region.

This study found that Chinese participants experiencing anxiety were significantly more likely to worry about the sequelae of Omicron compared to peers in North America and Western Europe.

Alopecia areata causes negative emotions and stress due to hair loss and emotional triggers.

This review highlights that disturbances in neuroimmune communication, particularly between sympathetic nerves and macrophages, may contribute to autoimmune diseases like rheumatoid arthritis and type 1 diabetes, and suggests potential therapeutic avenues by restoring this communication in preclinical and early clinical studies.

This study found that in pregnant rats, the suppression of ACTH responses to IL-1β is linked to the action of endogenous opioids and AP, with AP potentially inducing opioid inhibition through increased pENK-A expression.

This study found that chronic stress may inhibit hair follicle growth and melanogenesis in mice through modulation of the central HPA axis, with C57BL/6 mice appearing most sensitive to these effects.

This study found that combining ASA with conditioned medium from adipose tissue-derived MSCs may offer a promising approach for protecting against hippocampal injuries, suggesting potential synergistic therapeutic benefits that merit further investigation.

This study in mice demonstrated that stress or nerve growth factor injection increases sensory neuron activity related to skin innervation, suggesting a strong connection between stress perception and neurogenic skin inflammation.

This study observed that an 8-session mindfulness-based cognitive therapy reduced social anxiety and improved wellbeing in some individuals with alopecia areata, though effectiveness may depend on regular mindfulness practice.

This study observed that the development of the pars intermedia in long-tailed macaques is closely associated with changes in skin pigmentation during pre- and postnatal periods through melanocyte-stimulating hormone and ACTH activity.

This study found that adolescent girls with anorexia nervosa had lower hair cortisol concentrations compared to healthy and psychiatric controls.

This study utilized a mouse model of traumatic brain injury to reveal that acute neurotrauma triggers widespread lipid metabolism reprogramming and storage lipid accumulation in microglial and monocyte populations, leading to lysosomal dysfunction, inhibited autophagy, and exacerbated inflammation through a pathological feedback loop.

This study suggests that the neurosteroid allopregnanolone contributes to stress resistance in mice, and the ALLO mimetic drug alfaxalone may offer anxiolytic benefits without muscle-relaxant effects.

In this study, researchers identified that keloid fibroblasts respond to neurotransmitters from catecholaminergic nerves by producing bone matrix proteins, mediated by β1-adrenergic receptor activation, leading to fibro-osseous reprogramming; blocking this signaling in a rodent model prevented the development of keloid-like pathology.

This study describes "alarm reaction" histologic changes in pilosebaceous structures, including regression of hair matrix and alterations in sebaceous glands, affecting follicular and sebaceous gland morphology.

This study found that higher levels of cortisol (F) and cortisone (E) in hair before stroke onset were significantly associated with post-stroke depression and anxiety, suggesting they could serve as potential predictors for these mood disorders.

This study found that in males with alopecia areata, adult patients had significantly higher levels of adrenaline and prolactin compared to healthy controls, suggesting these hormones may play roles in the condition's development.

This study found that individuals with androgenetic alopecia experience significantly higher symptoms of anxiety, depression, and stress compared to controls, along with reduced self-esteem and life satisfaction, highlighting the importance of addressing psychological well-being in clinical treatments.

Lowering 3α,5α-THP in the hippocampus increases anxiety and depression in proestrous rats.

This study found that palmitoylethanolamide may stimulate allopregnanolone synthesis and reduce oxidative stress in astrocytes through PPAR-α activation, suggesting a neuroprotective role.

This case report presents a rare instance of recurrent ACTH-independent Cushing’s syndrome due to PBMAH, coinciding with the development of a pheochromocytoma, highlighting the need for thorough reevaluation in similar recurring cases.

This review discusses the role of neuroactive steroids in physiological processes and their potential involvement in neuropsychiatric disorders, but it reports no new experimental findings.

This case report describes a young woman with an adrenal oncocytic tumor of uncertain malignant potential, highlighting the need for ongoing surveillance due to possible malignancy.

This study observed that patients with androgenetic alopecia had higher alexithymia scores and more frequent anxiety compared to control subjects, although no conclusive link to depression was found.
