Background: Growth incidents usually progress in a fairly expected sequence; however, their timing and pattern vary across individual subjects. Biochemical biomarkers have an association with bone metabolism and produce signals which stimulate the growth and development of various craniofacial structures. Steroid dehydroepiandrosterone sulfate (DHEA-S) plays a major role in the initiation of growth hormone actions which has a significant role in promoting and accelerating skeletal maturation during puberty. The aim of this study was to investigate the correlation between salivary DHEA-S levels and cervical vertebral maturation (CVM) stages throughout the circumpubertal developmental period.
Methods: One hundred forty-one participants (70 males and 71 females), between 7 and 23years of age, were categorized into six cervical stages (CS) based on lateral cephalograms. Using a passive drooling technique, unstimulated whole saliva samples were collected from all enrolled subjects. DHEA-S levels were analyzed using the enzyme-linked immunosorbent assay (ELISA) and correlated with the six CVM stages.
Results: One-way analysis of variance ANOVA showed that the mean salivary DHEA-S levels at CS 3 and CS 4 were significantly different from the values recorded at other stages, and the two stages were statistically significant from each other. Pearson linear correlation of mean salivary DHEA-S levels from CS 1 to CS 6 showed a significant positive correlation.
Conclusion: Salivary DHEA-S can be used as a non-invasive indicator for detecting the pubertal growth spurt.

Background: Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder in women of reproductive age. Anovulation is one of the most important clinical features of PCOS, and insulin resistance (IR) is one of the critical pathogenic factors. Woxuanzhongzhou (WXZZ) is a traditional herbal formulation that has shown efficacy in treating PCOS combined with IR, but the underlying mechanism is not clear.

Objective: The effects of sex hormones remain largely unexplored in pheochromocytomas and paragangliomas (PPGLs) and gastroenteropancreatic neuroendocrine tumors (GEP-NETs).
Methods: We evaluated the effects of estradiol, progesterone, Dehydroepiandrosterone sulfate (DHEAS), and testosterone on human patient-derived PPGL/GEP-NET primary culture cell viability (n = 38/n = 12), performed next-generation sequencing and immunohistochemical hormone receptor analysis in patient-derived PPGL tumor tissues (n = 36).
Results: In PPGLs, estradiol and progesterone (1 µm) demonstrated overall significant antitumor effects with the strongest efficacy in PPGLs with NF1 (cluster 2) pathogenic variants.

Background: Alcohol intake is associated with a higher risk of estrogen receptor-positive (ER+) breast cancer (BC), presumably through its confirmed ability to increase sex hormone levels. Whether consuming alcohol within the recommended limit of one serving per day increases sex hormone levels among postmenopausal women taking aromatase inhibitors (AI) to inhibit estrogen production remains unknown. Therefore, we compared sex hormone levels following white wine to levels following white grape juice among ER + BC survivors taking AIs.

Cytochrome P450 17A1 (CYP17A1) catalyzes two enzymatic reactions in the biosynthesis of dehydroepiandrosterone (DHEA) from pregnenolone. In pregnant humans, the adrenal gland is responsible for DHEA biosynthesis, which is then sulfated by SULT2A1 and released into the bloodstream. This sulfated DHEA is subsequently taken up by the placenta and deconjugated to serve as a precursor for estrogen biosynthesis.

Backgrounds: Chronic respiratory complications such as asthma, bronchiolitis obliterans, and chronic bronchitis are prevalent among individuals exposed to sulfur mustard (SM). This study investigates the hormonal changes associated with SM-induced respiratory disorders.
Methods: A cross-sectional analysis was conducted involving 276 male participants exposed to SM during the Iraq-Iran war and 64 healthy controls.
