Drug Testing and Analysis, EarlyView.Sensitive LC‐HRMS methods were established for the detection of kisspeptin and its analogues in serum and urine, alongside their analytical and metabolic characterization. Stability studies were conducted in serum, plasma, and urine, highlighting the importance of appropriate sample handling for reliable anti‐doping analysis.

Developmental Dynamics, EarlyView.Abstract Background Integrin is an αβ heterodimeric receptor to the extracellular matrix; its binding to the matrix recruits focal adhesions to two NPxY motifs, the tyrosine phosphorylation sites in the cytoplasmic domain. Studies found that replacing tyrosines (Y) with phenylalanines (F) in the motif of β1 integrin displayed little developmental or ...

A small population of hypothalamic neurons govern fertility: the critical role of VAX1 in GnRH neuron development and fertility maintenance. [PDF]
, 2016 Fertility depends on the correct maturation and function of approximately 800 gonadotropin-releasing hormone (GnRH) neurons in the brain. GnRH neurons are at the apex of the hypothalamic-pituitary-gonadal axis that regulates fertility. In adulthood, GnRH

Role of SoxE transcription factors in development and disease
Developmental Dynamics, EarlyView.Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

Embryonic development of the Mediterranean starfish Hacelia attenuata
Developmental Dynamics, EarlyView.Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

European Eating Disorders Review, EarlyView.ABSTRACT Objective The albumin‐globulin ratio (AGR) is a biochemical marker reflecting nutritional and inflammatory status, with significant prognostic value in chronic conditions. This study examined its association with clinical/biochemical markers in adolescents with anorexia nervosa (AN) and atypical AN (AAN).
