This observational study found that endoscopic subcutaneous midface elevation with vertical SMAS plication safely and effectively rejuvenates the mid and lower face in patients under 45 with early facial soft-tissue ptosis, reporting no facial nerve injuries and minor complications like localized cicatricial alopecia and hematomas.

This study observed that PAD type III and trichohyalin are expressed earlier than their deiminated form during the first and second hair cycles in rat hair follicles, indicating a potential additional factor is involved in triggering deimination.

Human growth factor 20 can boost mouse whisker growth.

This study investigated the interdigital glands in sheep, highlighting their apocrine sweat glands' ultrastructural characteristics and positive lectin reaction, but reported no new clinical results.

This article discusses the mini-lift as a cosmetic procedure for minor cheek and neck laxity, emphasizing its benefits like quicker recovery and minimal incisions, but provides no new clinical data.

This study found that a high-fat diet in rats led to obesity, insulin resistance, and structural changes in the parotid salivary glands, with associated negative impacts on general health.

In this study, the authors reported that while deoxycholic acid effectively reduces submental fat, it can cause adverse effects such as edema, numbness, and skin necrosis, making knowledge of possible complications essential for clinicians.

The document recommends a multidisciplinary approach and experience sharing to advance facial feminization surgery as a medical field.

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, high-resolution ultrasound imaging revealed that DHT administration in male C57BL/6 mice leads to increased epidermal and dermal thicknesses and decreased skin elasticity, simulating structural changes associated with Androgenetic Alopecia.

This study found that BBS7 downregulation in occlusal hypofunctional periodontal ligament tissue is associated with reduced Sonic hedgehog signaling activity, potentially playing a key role in maintaining PDL homeostasis.

This study found that the transcription factor Trps1 acts as a novel regulator of the Wnt signaling pathway and early hair follicle progenitors in developing vibrissa follicles in mice.

This study found that the absence of Sostdc1 in mice alters mammary gland and hair follicle development, particularly by increasing vibrissae numbers and causing unusual nipple-like structures.

This study observed that cultured dermal papilla cells showed distinct functional properties from dermal fibroblasts, including lower proliferation rates, higher adhesion to collagen type IV, and different cell-matrix interactions.

This study proposes that the terminal tuft structure in sensory nerve endings, involving Schwann cell processes and axon fingers, potentially plays a role in mechano-electric transduction in rats.

This study found that prostaglandin D2 promotes androgen receptor and AKT signaling in human dermal papilla cells through the DP2 receptor, potentially contributing to androgenetic alopecia.

This study identified a large deletion in the desmoglein 4 gene as the genetic basis of the Iffa Credo "hairless" rat's skin phenotype, linking it to lanceolate hair mutations.

In this study, researchers developed a three-dimensional ultrastructural analysis tool using serial block-face scanning electron microscopy to reveal detailed nerve networks and muscle structures in human skin tissues, demonstrating the technique's potential to study structural changes in aging or disease.

This study found that dihydromyricetin may reduce fibrosis features in hypertrophic scars by affecting PI3K/AKT/mTOR signaling, but further research is needed to confirm causality.

In this study, the researchers found that constitutive activation of the EGFR in mice led to increased sebum production, enlarged sebaceous glands, and altered gene expression related to sebocyte proliferation and lipogenesis.

In this study, the researchers found that cholinergic signaling via M4 muscarinic receptors influences hair growth, with enhanced elongation observed upon activation with bethanechol, highlighting its potential role in hair biology using mouse models.

This study suggests that the C-terminal of AHF is crucial for its binding to keratin bundles and modulating the keratin meshwork in hair follicles.

Merkel cells are abundant in facial vellus hair follicles, especially during the anagen phase.

This review discusses nonsurgical techniques for facial masculinization and feminization in transgender patients and reports no new clinical findings, utilizing data from analogous procedures in cisgender individuals.

In this research, the author hypothesizes that curly hair is influenced by the contraction of the Arrector Pili muscle, suggesting that its relaxation through specific treatments could potentially modulate hair follicle curvature, but further studies are needed to confirm this mechanism.

In this review, the authors evaluated the potential of using the second to fourth digit ratio (2D:4D) as a predictor for androgenetic alopecia, suggesting future research directions but not reporting definitive results.

This study on mice found that activating TRPML channels with MLSA1 promoted hair regeneration, accelerated hair cycle transition, and influenced human dermal papilla cells to secrete hair growth promoting factors while reducing hair growth inhibitors and oxidative damage.

A 4kb fragment of the desmocollin 3 promoter targets gene expression to specific skin and hair follicle areas.

This study found that the unique crest feather formation in Polish chickens is driven by a 195-bp duplication in the HoxC10 gene region, which alters gene expression by modifying the genomic structure, suggesting a mechanism for diverse integumentary appendages in birds.
