This review discusses the challenges of interpreting observational studies on COVID-19 due to biases from non-representative samples, such as collider bias, and suggests better sampling methods to mitigate these issues.

This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.

Mouse Scube3 affects teeth, tongue, vibrissae, and eye development, but not facial structure or limb growth.

This study found that a ceria nanozyme-integrated microneedles patch accelerated hair regeneration in an androgenetic alopecia mouse model more effectively than minoxidil, with reduced application frequency and minimal skin damage.

This review reports that tinea capitis is uncommon in adults, with postmenopausal African American or Black women at higher risk, and emphasizes the importance of prompt antifungal treatment to prevent complications.

This study identified associations between alopecia areata and posttraumatic stress disorder, obesity, and alcohol use, reinforcing the need for psychiatric and alcohol use screening in these patients.

This study demonstrates a method using intravital imaging to observe sensory hair-cell development and regeneration in zebrafish, which may facilitate assays for drug discovery related to aural function preservation.

This review evaluates recent advances from 2016 to 2022 in the use of microbubbles and nanobubbles, highlighting their potential for safer diagnostic and therapeutic applications in radiology and medicine without the side effects associated with traditional methods.

This study found that maternal early-pregnancy serum ferritin concentrations were associated with lower DNA methylation levels at specific CpG sites in cord blood, with some associations persisting into childhood.

Regulatory T cells help prevent autoimmunity and have potential for treating autoimmune diseases.

This article discusses the need for rational strategies in developing hair loss drugs targeting specific events in hair follicle cycling, reporting no clinical findings but emphasizing the importance of understanding molecular controls.

The book is a valuable, comprehensive guide on hair transplantation, recommended for surgeons and students, with minor areas for improvement.

This study found that finasteride significantly reduced serum dihydrotestosterone levels, confirming its efficacy as a 5a-reductase inhibitor, while Permixon showed no effect in healthy male volunteers.

This case report presents the first successful treatment of perifolliculitis capitis abscedens et suffodiens using a regimen of adalimumab and baricitinib, resulting in almost complete healing after nine months.

This review discusses the evolution and current practices of Follicular Unit Extraction (FUE) in hair restoration surgery, reporting comparable patient outcomes to Follicular Unit Transplantation (FUT), though noting controversies in its adoption.

This article discusses hair angle manipulation using the Mega FUE® device but reports no clinical results; disclosure of the author's ownership of the manufacturing company is noted.

This article discusses the importance of artistic hairline design and clear outlining in planning the recipient area for hair transplants but reports no clinical results.

This case report describes a 65-year-old man diagnosed with atraumatic splenic rupture, which is rare and can occur without trauma, following sudden-onset left-sided abdominal pain.

This abstract discusses the uncertain role of the vascular system in hair loss and highlights the unexplained aspects of various types of alopecias; it reports no new research findings.

This study found that topical minoxidil can be effective in preventing flap necrosis during latissimus dorsi flap reconstruction in patients who have undergone neoadjuvant chemoradiation.

This study observed that a wearable electric stimulation device significantly promoted hair regeneration in rats and mice, outperforming conventional pharmacological treatments and enhancing growth factor secretion.

This study found that cultured dental papilla cells from various mammals can induce hair follicle regeneration and influence tissue formation, with outcomes dependent on donor age, tooth type, and host environment.

This review discusses neutrophil-associated and infiltrative scarring alopecias, as well as promising new treatments, but reports no new clinical results.

This case report describes a 4-year-old girl in Singapore with inflammatory tinea capitis, which improved with oral griseofulvin and selenium sulfide shampoo.

Doctors use their experience to choose treatments for scarring hair loss because it's hard to diagnose and treat.

This study developed a composite hydrogel that delivered multiple proteins, enhancing skin wound healing by accelerating closure and promoting hair follicle regeneration.

This study found that scalp medical tattooing effectively improved cosmetic appearance and concealed bifid parietal whorls without complications in the patients evaluated.

In this study, researchers used Mendelian randomization to find a significant genetic association between rheumatoid arthritis and an increased risk of alopecia areata, suggesting RA patients should be vigilant for potential AA development.

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.

This study found that hair from the vertex posterior is a reliable sampling region for detecting zolpidem intake, showing consistent drug concentration and peak position compared to other scalp regions.
