T he regulation of metabolism in bacteria is accomplished by a complex array of signal transduction systems, metabolic interactions, and gene regulatory relationships. For example, maintenance of the balance of carbon and nitrogen metabolism involves (as a partial list) ppGpp, cAMP, the NtrBC two-component system and the coupled Nac-controlled regulon, the leucine-responsive protein LRP, the ca...

BACKGROUND Dietary intake is known to influence glucose metabolism, but there is little consensus on the optimal distribution of macronutrient intakes during pregnancy to prevent gestational diabetes (GDM). OBJECTIVE We aimed to investigate whether macronutrient intake distribution during the second trimester of pregnancy was associated with glucose metabolism later in pregnancy. DESIGN Wom...

Folic acid, which provides the transfer of single carbon atoms in synthesis reactions and metabolic cycles metabolism, is very important for metabolism. acid also plays an role nucleotide methylation reactions. There are many disorders caused by defective folic metabolism lack acid. Today, innovative, cost-effective methods needed to develop determination methods. The main objective this study ...

Introduction: Colorectal cancer (CRC) is the second leading cause of death in developed countries, mainly as a consequence metastatic spread. Secreted proteins are essential to communicate cells with tumor- microenvironment, favoring tumor progression and metastasis. The conditioned medium or cellular secretome, including exosomes, has demonstrated be rich source effectors biomarkers metastatiz...

The purpose of this study was to investigate the metabolism of Adenosine triphosphate (ATP) in skeletal muscle resistance arterioles and to determine whether this metabolism is altered during the rapid growth phase of the rat. We attempted to quantify ATP metabolism in gastrocnemius first-order arterioles from 8-, 10-, and 12-week-old rats. We measured ATP metabolism using an ATPase/GTPase assa...

The first step in gonadotropin-releasing hormone (GnRH) action involves the binding of GnRH to a plasma membrane receptor. Calcium has been implicated as a second messenger molecule. More recently, it has been suggested that the products of phosphoinositide metabolism may act as a second messenger for GnRH-stimulated release of luteinizing hormone (LH). To be considered a second messenger, howe...

the study on biochemical changes in brain tissue indicates that there are considerable variations in metabolism of energy in this tissue within the first three weeks of life. this phenomenon coincides with the increase of brain energy during that period of life. there are, indeed, various factors, involved in the changing process. hormones and thyroid hormones in particular are of the most impo...
