This study observed that using ultra-high-frequency ultrasound with 70 MHz probes effectively assessed the distribution of hyaluronic acid fillers and improvements in nasolabial fold wrinkles, with significant changes in dermal thickness and wrinkle scores maintained 24 weeks after treatment.

This study utilized 3D ultra-high frequency ultrasound to effectively detect different disease phases of alopecia areata by visualizing hair follicle structures and identifying unique pathological signs, offering a promising non-invasive diagnostic tool that surpasses conventional methods.

3D ultrasound can detect hair follicle changes and disease phases in alopecia areata.

This study found that during dialysis, lower plasma-potassium levels were associated with hyperglycemia, suggesting potassium correction is vital when using glucose-rich dialysate.

This review discusses various non-invasive methods for diagnosing alopecia areata, highlighting that trichoscopy signs like short vellus hairs and yellow dots are sensitive indicators of the condition, while advanced imaging techniques provide valuable information on hair follicle status and scalp inflammation.

This study found that testosterone therapy increased bone mineral density in older men with low testosterone, and combining it with finasteride may reduce prostate enlargement associated with testosterone treatment.

Wnt/β-catenin signaling is crucial for cell fusion in placental development.

This case report describes a male patient with aromatase deficiency, revealing that a c.628G>A mutation can lead to varied clinical features, such as low bone mass and normal metabolic profiles.

This review discusses the integration of ultrasound in dermatology for improved lesion visualization and diagnosis, highlighting recent technological advancements like handheld devices and high-frequency probes, and reports no clinical results.

This review examines the impact of biotin, vitamin B12, and zinc on male reproduction, emphasizing their role in spermatogenic failure, but reports no new clinical results.

This study suggests that the testosterone analogs 7α-Methyltestosterone and 7α-Ethyltestosterone may offer promising androgenic, progestogenic, and anabolic properties for development as male contraceptives.

This abstract introduces the concept of follicular units (FUs) in the human scalp but presents no new research findings.

This study reports that high-frequency ultrasound can characterize frontal fibrosing alopecia by assessing dermal atrophy, hair follicle changes, and subclinical inflammation.

This article reviews the use of high-frequency ultrasonography to visualize nail units and scalps in dermatology, highlighting its potential benefits for disease assessment and treatment monitoring, but reports no new clinical results.

The document concludes that hair restoration has improved with follicular unit transplantation, making it more scientific and precise.

This review highlights the increasing clinical applications of high-frequency ultrasonography in dermatology, particularly for assessing the depth of skin tumors and monitoring inflammatory skin diseases, but reports no new clinical results.

This study found that combining high-frequency ultrasound with clinical examination significantly improved the diagnostic accuracy of invisible subcutaneous lesions from 47.3% to 80.8%, especially for conditions like epidermoid cysts and lipomas, although it was less effective for rarer lesions such as dermatofibromas.

This study found that high-frequency ultrasound was effective in localizing deep tumor margins in basal cell carcinoma, suggesting its utility in selecting therapeutic approaches.

In this study, researchers found that using the FUE method, performed by surgeons instead of technicians, allows for more precise follicular unit extraction than the traditional FUT method, potentially improving outcomes and donor area utilization in hair transplantation.

In this study, the Instant Follicular Hair Unit Transplant technique demonstrated superior hair growth compared to conventional FUE in patients with androgenetic alopecia, although it requires a steeper learning curve for surgeons.

In this rodent model study, the researchers reported that using low-intensity focused ultrasound with phenytoin enhanced its anti-epileptic efficacy by disrupting plasma protein binding in a region-specific manner, reducing seizure frequency and duration.

This case study observed that high-intensity focused ultrasound treatment significantly improved hair density and reduced hair loss in a female patient with androgenetic alopecia, with no adverse events reported.

This study found that a new three-dimensional high-frequency ultrasound (3D-HFUS) can successfully visualize skin tumors and inflammatory hair diseases, offering promising noninvasive diagnostic and evaluation capabilities compared to traditional two-dimensional methods.

This report describes benefits of advanced hair transplant techniques, micro-FUE and U-FUE, which may result in natural, undetectable hair restoration and discrete post-procedure appearance.

This study found that using an ultrasound hollow microneedle array enhanced transdermal delivery of finasteride, accelerating hair regrowth in mice with androgenetic alopecia compared to other delivery methods.

A 4-year-old girl had a rare hair disorder affecting only part of her scalp.

In this study, mozuku-derived ultra-high-molecular-weight fucoidan was found to inhibit the growth of skin bacteria like Staphylococcus aureus but not other tested bacteria such as Cutibacterium acnes.

This article discusses the establishment and global adoption of standardized terminology for follicular unit excision (FUE) by the ISHRS, which aids effective communication among hair restoration practitioners.

FUE hair transplants have improved to give more natural results with less scarring and pain.

This study suggests that fusaric acid at nontoxic concentrations may activate signal transduction in plants which could aid in the plant-defense responses against Fusarium spp.
