This study found that dihydrotestosterone (DHT) suppresses prostaglandin E2 and TGF-β induced IGF-I gene promoter activity in osteoblasts, suggesting complex interactions among bone growth regulators and potential complications from anabolic steroid use.

This paper presents a case study of a 21-year-old male with thyroid hemiagenesis, where the left thyroid lobe and isthmus are absent, and discusses the anomaly's potential clinical consequences based on existing literature.

In this study, Epimedii Folium extract was found to enhance melanin production and promote pigmentation through mechanisms involving the MAPK/ERK1/2 pathway in both in vitro and in vivo models.

This study observed that downregulation of laminin-511 plays an important role in hair regression during the catagen stage in mice.

This study identified two distinct VDR gene mutations among Lebanese families with hereditary vitamin D-resistant rickets, noting varied treatment responses and promising outcomes despite severe phenotypes.

In this retrospective study of eight Saudi children with hereditary vitamin D resistant rickets, researchers observed that adjunctive cinacalcet appeared safe and showed initial promise in improving serum PTH levels, though further investigation is needed to confirm its efficacy.

This study explored professionals' insights on eyebrow transplantation, finding that while the procedure can enhance appearance and confidence, it also carries risks such as potential complications and costs, emphasizing the need for thorough pre-operative consultations.

This case study reported on a 3-year-old child with vitamin D-dependent rickets type II treated in the Gaza Strip, whose condition deteriorated despite vitamin D and calcium treatments, leading to recurrent chest infections, respiratory failure, and eventual death.

Hormones significantly affect skin health, with vitamin D playing a key role.

This article discusses the rationale, design, and significant findings of the long-running Rotterdam Study but reports no new clinical results.

This review discusses experimental data, technologies, and genetic factors related to stem cell niches, highlighting their role in tissue regeneration and diseases, but reports no new results.

This study reviews the evolution and modifications of microneedle drug delivery systems, initially designed for percutaneous use, now expanded for targeting a variety of tissues and organs such as ocular, oral mucosal, and gastrointestinal, suggesting widespread future applicability.
