Increased tumor necrosis factor alpha and interleukin-6 serum levels and their correlation with laboratory parameters in patients with imported malaria [PDF]

open access: yesArchives of Biological Sciences, 2012
In malaria, blood concentrations of proinflammatory cytokines, such as tumor necrosis factor alpha (TNF-α) and interleukin (IL)-6, are increased. In a study which included 34 patients, TNF-α and IL-6 were examined in two phases, immediately after the ...

Neuroendocrinology of Lactation

open access: yesJournal of Investigative Dermatology, 1974
Although other hormones influence the quantity of milk secretion, prolactin and adrenal corticosteroids are essential for initiating and maintaining lactation. During pregnancy high levels of estrogen and progesterone inhibit lactation, and elevation of prolactin and ACTH-adrenal corticosteroid levels result in the initiation of lactation at the end of

Respiratory complex I‐mediated NAD+ regeneration regulates cancer cell proliferation through the transcriptional and translational control of p21Cip1 expression by SIRT3 and SIRT7

open access: yesMolecular Oncology, EarlyView.
NAD+ regeneration by mitochondrial complex I NADH dehydrogenase is important for cancer cell proliferation. Specifically, NAD+ is necessary for the activities of NAD+‐dependent deacetylases SIRT3 and SIRT7, which suppress the expression of p21Cip1 cyclin‐dependent kinase inhibitor, an antiproliferative molecule, at the translational and transcriptional

TOMM20 as a driver of cancer aggressiveness via oxidative phosphorylation, maintenance of a reduced state, and resistance to apoptosis

open access: yesMolecular Oncology, EarlyView.
TOMM20 increases cancer aggressiveness by maintaining a reduced state with increased NADH and NADPH levels, oxidative phosphorylation (OXPHOS), and apoptosis resistance while reducing reactive oxygen species (ROS) levels. Conversely, CRISPR‐Cas9 knockdown of TOMM20 alters these cancer‐aggressive traits.

Enantioselectivity of (321) chiral noble metal surfaces: A Density Functional Theory study of lactate adsorption [PDF]

open access: yes, 2013
The adsorption of the chiral molecule lactate on the intrinsically chiral noble metal surfaces Pt(321), Au(321) and Ag(321) is studied by Density Functional Theory calculations. We use the oPBE-vdW functional which includes van der Waals forces on an ab initio level.

Dysoxia and lactate [PDF]

open access: yesArchives of Disease in Childhood, 1999
Disturbances of oxygen supply or cellular oxygen metabolism are common in critically ill patients. An understanding of dysoxia, or oxygen limited energy depletion, requires an understanding of the normal physiology of cell oxygen metabolism, and the compensatory mechanisms that supply high energy molecules under conditions of hypoxia.

Purification and characterization of a thermophilic NAD+‐dependent lactate dehydrogenase from Moorella thermoacetica

open access: yesFEBS Open Bio, EarlyView.
The thermophilic acetogenic model organism Moorella thermoacetica can utilize lactate as substrate. The formation of lactate by reduction of pyruvate is energetically favorable, but the reverse reaction, the oxidation of lactate to pyruvate with NAD+ as electron acceptor is challenging.

Piezo1 channels enhance anabolic signaling activation induced by electrical stimulation of cultured myotubes

open access: yesFEBS Open Bio, EarlyView.
By using an electrical pulse stimulation (EPS)‐based in vitro exercise model and chemical activation/inhibition of mechanosensitive Piezo1 channels, we explored changes in protein synthetic response in cultured C2C12 myotubes. Our data showed that application of Piezo1 activator (Yoda1) during EPS significantly enhances the rate of protein synthesis in

Feasibility of measuring superior mesenteric artery blood flow during cardiac surgery under hypothermic cardiopulmonary bypass using transesophageal echocardiography: An observational study

open access: yesAnnals of Cardiac Anaesthesia, 2016
Background: Abdominal complications being rare but results in high mortality, commonly due to splanchnic organ hypoperfusion during the perioperative period of cardiac surgery.

Bioengineering facets of the tumor microenvironment in 3D tumor models: insights into cellular, biophysical and biochemical interactions

open access: yesFEBS Open Bio, EarlyView.
The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.
