In this case–control study, the researchers in Ukraine found no significant link between VDR rs2228570 polymorphism and decreased serum BDNF levels, though they observed a moderate correlation between serum BDNF and 25-OH Vitamin D levels in patients with thyroid disorders.

This narrative review summarizes evidence on NAD⁺ biosynthesis and turnover, highlighting that while NAD⁺ precursors like NR and NMN consistently boost NAD⁺ levels in preclinical and human studies, clinical outcome results remain varied, indicating a need for more standardized human trials.

This study presents a method using liquid chromatography tandem mass spectrometry to quantify biotin in plasma and serum, and explores how high biotin intake can interfere with diagnostic immunoassays that utilize biotin-streptavidin technology, potentially leading to misdiagnosis of endocrine disorders.

This review discusses the potential of polydeoxyribonucleotide (PDRN) for various dermatological treatments and highlights its significant effects on wound healing, anti-aging, acne scars, and hair loss, but emphasizes the need for further clinical studies.

This study observed that acanthosis nigricans is highly prevalent in Latin American youths, especially at the knuckles, and may indicate early insulin resistance even in those with a normal BMI.

Some people have a genetic variation that makes them less effective at breaking down drugs.

This study confirms the presence of large structural variations in the genome of Nellore cattle, which may contribute to their environmental adaptation to tropical regions.

This study found significantly higher levels of the protein ULBP3 in patients with alopecia areata incognita compared to other hair loss conditions and healthy controls, suggesting ULBP3's potential as a diagnostic marker for AAI.

This study found that a school-based nutritional program improved adolescents' waist measurements, blood counts, and reduced rates of certain skin and mucosal conditions associated with vitamin deficiency.

This study found that in patients with elevated fibrinogen levels undergoing revision rhinoplasty, PDRN decreased M1 cytokines and increased M2 cytokines, potentially offering a new therapeutic approach, but further research is needed to understand its mechanisms and effects fully.

This study reports that the Swedish newborn screening program for phenylketonuria, galactosaemia, and biotinidase deficiency is effective, with high sensitivity and specificity, and lower false positive rates compared to other countries, while genetic variants impact detection and incidence patterns in Sweden.

This study suggests that PLA2R1 overexpression in PMN affects the podocyte cycle and may involve an additional immune response, which could provide new directions for PMN treatment development.

This study suggests that hair loss disorders like Marie Unna hereditary hypotrichosis may result from mutations that disrupt post-transcriptional regulation of HR protein expression by PCPB2 interacting with Hr mRNA.

Researchers created a simple tool to predict bladder blockage from prostate enlargement using urine flow rate and prostate volume.

This study found that BDNF gene polymorphism was significantly associated with depression in patients with autoimmune thyroiditis and hypothyroidism in the Western Ukrainian population, unlike VDR and NMDA polymorphisms.

This phase II trial found that BI 2536 demonstrated limited antitumor activity across five solid tumor types, with no confirmed objective responses observed.

This study found that blood and milk somatic cells show promise as matrices for monitoring illicit recombinant bovine somatotropin use in dairy cattle through gene-expression assays.

In this study, researchers found a significant association between the rs13405699 SNP at 2q31.1 and male pattern baldness among Han Chinese men, suggesting genetic influence on this condition in this population.

This study found that overexpressing the BMP inhibitor Noggin in transgenic mice led to a significant loss of nontylotrich hair follicles, suggesting a critical role for BMP signaling in hair follicle morphogenesis and cycling.

This study found that BMP6 and Wnt10b competitively regulate the transition between hair follicle growth phases, offering new insights into hair follicle cycling and potential hair loss treatments.

This study reported that using plain bottles instead of commercial kits for extracting platelet-rich plasma may be an effective method for treating hair loss.

In this study, the authors observed that controlled microflora in gnotobionts leads to delayed maturation of T-dependent lymphocytes in the thymus, affecting cellular immunity reactions.

This review discusses biotinidase deficiency, noting that biotin treatment from birth can prevent symptoms, but acknowledges the complexity and need for further understanding due to late-onset cases with varied clinical findings.

This study found that Bnip3L and caspase-12 were differentially expressed during the first catagen stage of mouse hair follicle development under normal physiological conditions.

In this study, researchers found that using regional nerve blocks (STN and SON blocks) for anesthesia in platelet-rich plasma treatment for hair regrowth resulted in significantly less pain and better analgesia compared to the more common ring block technique.

This study found differential expression of growth factors and cytokines in umbilical cord blood-derived platelet-rich plasma, with the highest concentrations observed in the B blood type, but also noted weak correlations with ABO blood groups, suggesting other influencing factors.

This study identified altered mRNA and lncRNA profiles in NS scalp tissues, highlighting CDKN2AIP as a downregulated gene involved in a ceRNA network.

In this study, a 54-year-old woman with short bowel syndrome developed biotin deficiency and associated symptoms while on home parenteral nutrition lacking biotin, which improved significantly after supplementation.

This study highlighted knuckle hyperpigmentation as an early sign of vitamin B12 deficiency, indicating a potential link to megaloblastic anemia in the vegetarian population in India.
