The notochord is an axial structure required for the development of all chordate embryos, from sea squirts to humans. Over the course of more than half a billion years of chordate evolution, in addition to its structural function, the notochord has acquired increasingly relevant patterning roles for its surrounding tissues. This process has involved the co-option of signaling pathways and the acquisition of novel molecular mechanisms responsible for the precise timing and modalities of their deployment.

Cavitary sarcoidosis is a rare form and represents non-caseating granulomatous diseases of the lungs exhibiting a narrow range of differential diagnoses. The peculiarity of this case lies in the difficulty of distinguishing atypical manifestations of pulmonary sarcoidosis, such as cystic lesions, from cavernous tuberculosis. Both possess similar clinical and radiological features.

Objective: Aim: To study the peculiarities of food tolerance disorders in premature infants, taking into account the risk factors of gestational age and maternal labor, the peculiarities of the course of perinatal pathology, in order to determine pathogenetically sound clinical and laboratory criteria.
Patients And Methods: Materials and Methods: A comprehensive clinical and laboratory evaluation was performed on 67 preterm infants of gestational age 32 to 33/6 weeks with severe food tolerance disorders in perinatal pathology. The comparison group consisted of 31 newborns with gestational age of 34 to 37 weeks.
