In this study, photodynamic therapy significantly reduced inflammatory acne lesions and sebum secretion, possibly by inducing apoptosis in sebaceous glands and down-regulating TLR-2 and TLR-4 expression.

This study found that compound 2g inhibits steroid sulfatase effectively without exhibiting estrogenic activity, making it a promising candidate for breast cancer treatment.

This letter to the editor discusses a potential link between new onset alopecia areata and SARS-CoV-2 infection, but reports no new clinical results.

Clinical studies reported that finasteride reduces scalp dihydrotestosterone levels and improves hair growth in men with androgenetic alopecia, supporting its role as a treatment option.

This study concluded that men with benign prostatic hyperplasia receiving steroid 5α-reductase inhibitors, such as dutasteride or finasteride, have a higher risk of developing new onset type 2 diabetes compared to those taking tamsulosin.

This review discusses the complex links between polycystic ovary syndrome, insulin resistance, and potential metabolic risks starting in adolescence, noting the need for early screening and treatment but reports no new clinical results.

This study found that human outer root sheath cells express VEGF receptor-2, and exogenous VEGF165 significantly stimulates their proliferation through activation of the ERK signaling pathway.

This study reported that Sonic hedgehog signaling is crucial for hair follicle development, with its expression being significantly induced in normal embryonic hair germs but inhibited in certain experimental models.

This review discusses the potential of evaluating hair follicle characteristics as early indicators of vascular impairment and organ damage in pre-diabetic individuals, but reports no new clinical results.

This study found that diphlorethohydroxycarmalol significantly increased prostaglandin $E_2$ synthesis in HaCaT human keratinocytes by upregulating COX-1 and COX-2 expression, suggesting potential benefits from elevated $PGE_2$ production.

This study found that COX-2 expression in normal rat skin is linked to the hair cycle, with varying levels observed in different skin structures during anagen, catagen, and telogen phases.

This study improved a hair analysis method to estimate the days of continuous ingestion of hay-fever medicines, with an average error of about 2 days from actual ingestion.

In this study, researchers found that the microRNA miR-1199-5p may reduce the expression of SRD5A2 in benign prostatic hyperplasia tissues, potentially contributing to the failure of 5-α reductase inhibitor therapy in some patients.

This study observed that deleting ARNT in keratinocytes of mice reduced zigzag hair production and altered hair follicle differentiation, likely by affecting the expression of specific cyclin-dependent kinase inhibitors.

In this study, Nrf-2-expressing hair follicle mesenchymal stem cells showed the most significant therapeutic effect in a rat model of ulcerative colitis, suggesting a new potential treatment for the disease.

In this study, itraconazole was shown to accumulate in the deeper skin layers of guinea pigs after oral administration, suggesting this delivery method effectively targets infective organisms there.

This study found that fermented red ginseng marc alleviated skin lesions, reduced inflammation, and demonstrated antioxidant effects in an AD-like mouse model, suggesting potential therapeutic applications for atopic dermatitis.

This study found that 2MbisP increases epidermal thickening more rapidly than atRA in rhino mice, while both compounds similarly reduce utricle size.

This study observed that DDAIP-HCl enhanced the permeation of minoxidil through human cadaver skin, suggesting potential for improved treatment efficacy in male pattern hair loss.

This review discusses low level laser therapy for hair loss but reports no new research findings; it serves as an introduction to understanding existing knowledge before upcoming evaluations of recent studies.

Low-dose Minoxidil combined with Spironolactone helps reduce hair loss and improve hair density in women, with some mild side effects.

In this study, researchers identified two types of potassium channels, BK and Kv4.2, in rat Merkel cells and reported that these channels play important roles in repolarizing action potentials and maintaining resting membrane potentials, potentially influencing tactile encoding in these cells.

This study observed that while hair glucocorticoids were linked to type 2 diabetes, there was no social gradient in glucocorticoid levels among different socioeconomic groups, suggesting these biomarkers may not significantly contribute to understanding socioeconomic health disparities in diabetes.

In this study, researchers identified significant differences in lipid composition between grey and black hair follicles in women with type 2 diabetes and healthy controls, suggesting these lipids may contribute to the production of grey hair and may offer targets for anti-grey-hair treatments.

This study explores potential strategies for targeted drug delivery specifically to pancreatic beta-cells in type 2 diabetes treatment, highlighting methods for inducing drug expression in beta-cells, suitable drug carriers, active targeting peptides, and optimal administration routes.

In this mini-review, recent insights suggest a possible role of type-2-related immunity in diseases like alopecia areata, vitiligo, and localized scleroderma, though whether this immune response benefits or worsens these conditions remains unclear.

In this study, patients with diabetic retinopathy and peripheral occlusive arterial disease had significantly longer diabetes duration, higher HbA1c levels, poorer glycemic control, and were more often smokers compared to those without arterial disease, suggesting these factors contribute to disease development.

The researchers reported that nicotinic acid normalized excessive sebaceous lipogenesis without affecting basal lipogenesis and suggested potential anti-acne benefits.

This study reported that NRP2 expression in melanocytes and melanocyte stem cells is linked to migration inhibition and potentially melanoma progression, suggesting its role as a target for understanding melanoma and hair follicle biology.

This study found significant upregulation of IDO-1 and IDO-2 in human basal cell carcinomas, suggesting that IDO production may confer immune privilege characteristics to the tumors, potentially impacting their growth.
