In light of the mitochondrial biogenic capacity of SB

In AIS women, autonomic nerous program activity was reported to be higher than con trols. The double neuro osseous concept for AIS pathogenesis in girls postulates developmental disharmony between somatic BAY 11-7082 and autonomic nervous systems exaggerated by hor mones providing endemic skeletal overgrowth and expressed in the back and start. The theory predicates AIS pathogenesis in girls on dysfunction in one or both of two putative normal mechanisms involved with trunk growth, each acquired in evolution and unique to humans, specifically, Physiological trunk thickness skeletal growth influenced hor monally and supplemented by the sympathetic nerous system acting symmetrically. Physical trunk postural mechanisms of the somatic nervous system establishing commonly to the growing and biomechanically changing keletal ramework. There's preliminary evidence suggesting the hypoth alamus of some standard juvenile girls, but not boys, func tions with central leptin resistance of the somatotropic axis. This Metastatic carcinoma procedure may reduce the energy dedicated to female skeletal progress thus conserving energy for reproductive growth. AIS in girls is viewed here as generally caused by improved central leptin sensitivity of hypothalamic sympathetic functions and, in certain girls, of the somatotropic neuroendocrine axis. These concepts provide an evolutionary and biological perspective of energy homeostasis, specifically involving white adipose tissue as triglycerides, where the double neuro osseous theory is formulated storing surplus energy. At the molecular level, disharmony between genes is set up. Gene versions that could influence the biology of AIS pathogenesis are believed OC000459 in relation to body mass index, timing of puberty, leptin, leptin receptor defi ciency, changes in hypothalamic resistancesensitivity to leptin, some hormones regarded as linked to AIS pathogenesis, and certain genetically modified mice. The double neuro osseous concept fits evidence that AIS might not be an individual condition. That it explains by different relative contributions towards the start disability by the somatic and autonomic nervous systems, which can vary between subjects. The goals of this paper are to, outline some anthropometric findings for AIS girls not explained by prevailing theories of pathogenesis, give a new theoretical framework for AIS patho genesis in girls to describe the findings and connect knowledge from a few biological areas, suggest tests of the theory including hormonal stud ies, concentrate on therapeutic implications and some possible manipulatable triggers, consider an evolutionary perspective for the pathogenesis of AIS in girls stemming from female fat deposition in puberty, and foster new thinking and research to enhance causal knowledge of AIS pathogenesis.
