This literature watch compiles recent studies on photobiomodulation therapy across various applications, offering no new empirical findings.

In this case report, a male patient with hair loss showed unusually high testosterone levels without other symptoms or supplement use; follow-up testing revealed normal levels, showcasing the importance of considering testosterone-protein binding differences and using equilibrium dialysis for accurate assessment.

In this study, only Vdr-knockout rats showed both abnormal skin formation and alopecia, which may provide insights into vitamin D receptor function and its role in the hair growth cycle.

This article discusses a new device for visualizing and quantifying skin distribution of a radioactively labelled compound, but reports no new clinical results.

This study found that in male mouse pancreatic islet β cells, testosterone enhances glucose-stimulated insulin secretion by being locally converted into dihydrotestosterone and estradiol.

This study explains that while trichothiodystrophy and xeroderma pigmentosum share genetic defects, TTD patients primarily exhibit issues in transcription initiation, not the increased skin cancer risk seen in XP.

This case study describes a 15-year-old girl with a Sertoli–Leydig cell tumor who showed high androgen levels and steroidogenic responses similar to patients with polycystic ovary syndrome before surgery.

In this study, researchers observed that phospholipid-calcium carbonate hybrid nanoparticles effectively delivered Tofacitinib citrate topically, which significantly inhibited hair follicle apoptosis and promoted hair growth in a mouse model of chemotherapy-induced alopecia, compared to a traditional Tofacitinib solution.

In this study, researchers reported telocytes in the dermis of silky fowl embryos at different developmental stages, highlighting their immunophenotypes and interactions with other cells.

In this case study, a 15-year-old girl with multiple trichoepitheliomas on her face saw a 90% reduction in lesions after combined cryotherapy and topical tretinoin treatment, with no scarring or recurrence over four years.

This study found that TET2 plays a tumor-suppressive role in preventing squamous cell carcinomas by regulating 5-hydroxymethylcytosine levels, suggesting therapeutic potential for DNA methylation dynamics.

This study found that the yeast androgen screen (YAS) could detect the activity of methyltestosterone in urine for a longer period than classical GC/MS, potentially identifying long-lasting metabolites.

The FDA approved a new breast cancer treatment, found flu shots may reduce heart risks, questioned the safety of fast-tracked drug approvals, showed statins don't help with certain pneumonia, and approved a new dementia imaging agent.

This source reports that thymosin beta 4 accelerated dermal wound repair in phase 2 clinical trials for pressure ulcers, stasis ulcers, and epidermolysis bullosa wounds and was well tolerated.

New treatments for vitiligo, including the first FDA-approved option, are improving patient care and quality of life.

Entadfi, a mix of finasteride and tadalafil, is used for BPH.

This study observed nestin-GFP expressing stem cells in the hair follicle bulge of living mice using high-resolution in-vivo multiphoton tomography, allowing migration tracking within their natural skin environment.

This letter to the editor discusses data from a study on troglitazone for lipodystrophy, noting significant increases in subcutaneous fat without dietary changes.

This study observed that using ex vivo gene therapy to modify skin cells in a pre-graft model improved dermal-epidermal junction adhesion strength and maintained collagen production over time, suggesting a potential treatment approach for recessive dystrophic epidermolysis bullosa skin wounds.

This study found that monitoring endogenous steroid metabolites in serum may improve the detection of testosterone doping by highlighting promising biomarkers.

This review discusses the experimental strategies and technological challenges of proton minibeam radiotherapy (pMBRT) and reports no clinical results; it highlights the potential of using a 3 GHz linear accelerator for precision therapy research.

This study found that using urine tenofovir monitoring for PrEP adherence is well-accepted and may help overcome adherence barriers among participants at a U.S. urban clinical center.

This review outlines various 3D bioprinting techniques and bioinks used for creating artificial tissues and organs, emphasizing their potential in addressing organ transplant shortages and advancing drug testing, while acknowledging existing challenges and future prospects.

This article discusses the range of skin-related side effects caused by chemotherapy and radiotherapy, including novel patterns emerging with targeted therapies, but does not report new clinical results.

In this study, Tithonia diversifolia extract was found to improve certain digestive parameters in crossbred sheep but did not enhance growth performance, as the improvements in digestion did not translate into increased body weight or feed conversion.

In this study, researchers developed de novo designed hetero-bifunctional proteins as an alternative approach for targeted protein degradation, successfully targeting BCL-xL for degradation in cells and inducing apoptosis, which may expand the range of addressable E3 ligases and disease targets.
