OBJECTIVES: The common femoral artery is the standard site for immediate vascular access when initiating adult venoarterial extracorporeal membrane oxygenation. However, this approach is fraught with problems such as femoral artery occlusion, distal limb ischemia, reperfusion injury resulting in compartment syndrome, retroperitoneal hemorrhage, thrombosis, embolization, and most importantly, pulmonary edema. Here, we show our preference of using the subclavian artery with a side graft as a different cannulation technique for outflow of extracorporeal membrane oxygenation, which can avoid complications associated with different access techniques...

PURPOSE: Environmental and nutritional disorders during perinatal period cause metabolic dysfunction in the progeny and impair human health. Advanced glycation end products (AGEs) are primarily produced during metabolism of excess blood glucose, which is observed in diabetes. Methylglyoxal (MG) is a precursor for the generation of endogenous AGEs, which disturbs the metabolism. This work aimed to investigate whether the maternal MG treatment during lactation programs the progeny to metabolic dysfunction later in life...

BACKGROUND: Removal of the follicular content by ultrasound-guided transvaginal follicle aspiration (TVFA) may fail to induce immediate atresia and loss of function, resulting in the occurrence of residual follicles (RF). The aims of this study were to characterize the blood flow in RF and to determine the effects of the treatment with estradiol benzoate on RF fate. Lactating, cyclic Holstein-Gir crossbred cows were used. In Experiment 1, follicular wave emergence (D0) was synchronized in cows (n = 10) and follicular growth was then monitored by transrectal ultrasonography from D0 to D8, followed by TVFA of the largest follicle present on the ovaries 24 h later...

In addition to its role as metabolic substrate that can sustain neuronal function and viability, emerging evidence supports a role for l-lactate as an intercellular signaling molecule involved in synaptic plasticity. Clinical and basic research studies have shown that major depression and chronic stress are associated with alterations in structural and functional plasticity. These findings led us to investigate the role of l-lactate as a potential novel antidepressant. Here we show that peripheral administration of l-lactate produces antidepressant-like effects in different animal models of depression that respond to acute and chronic antidepressant treatment...

Nitazoxanide (NTZ) is a broad-spectrum anti-parasitic drug used against a wide variety of protozoans and helminthes. Albendazole, its active metabolite albendazole sulfoxide (ABZSO), is one of the drugs of choice to treat both intestinal and tissue helminth and protozoan infections. However little is known regarding their impact on the metabolism of parasites. The aim of this study was to compare the in vitro effect of NTZ and ABZSO in the glycolysis of Taenia crassiceps cysticerci. The cysticerci were treated with 1...

This study aimed to determine whether heat stress (HS) could induce autophagy in immature boar Sertoli cells (SCs) and test whether HS-induced autophagy could regulate lactate secretion by SCs. Cultured immature boar SCs were incubated at 43 °C for 30 minutes. The ratio of LC3B-II to LC3B-I and the mRNA transcript levels of LC3B showed time-dependent changes 0 to 48 hours after HS treatment, which peaked at 24 hours and increased by 30.25% or 260%, respectively, compared with control SCs. The density of autolysosomes, which were labeled with a red dye, was higher at 24 hours than at any other time point...

Sialic acid (Sia) contents and bioaccessibility (BA) in human milk (HM) and infant formulas (IFs) were determined, and Sia intakes by infants between 0-6 months of age were evaluated. Total Sia contents in HM decreased during lactation from 136.14 to 24.47 mg/100 mL. The total Sia contents in IFs (13.15-25.78 mg/100 mL) were lower than in HM, and were not related to the addition of ingredients acting as sources of Sia in their formulation. The Sia intakes derived from IFs consumption were lower than in HM, and only one IF reached the intakes provided by HM from the age of two months...

BACKGROUND: There is a lack of reliable biomarkers that can identify and grade acute hypoxic-ischemic encephalopathy in newborns. MicroRNAs (miRNA) are short, non-coding strands of RNA that are released into the circulation in response to tissue stress and injury. Some miRNAs are highly tissue specific and thus may potentially be non-invasive biomarkers of neonatal hypoxic-ischemic brain injury. OBJECTIVE: The aim of this study was to characterize the temporal expression of selected circulating miRNAs in a clinically relevant piglet model of neonatal hypoxia-ischemia (HI)...

Hypoxia Inducible Factors (HIFs) are master regulators of glycolytic metabolism. HIFs consist of a constitutive HIFbeta (HIFβ) subunit and a HIFalpha (HIFα) subunit, whose half-life depends on prolyl-hydroxylases activity. Inhibition of prolyl-hydroxylases by hypoxia or transition metals, or augmentation of HIFα subunit levels by hormonal stimuli lead to a higher HIF transcriptional activity. On the other hand, it is well known that lactate produced by Sertoli cells is delivered to and used by germ cells as an energy substrate...

Cow's milk is an important source of proteins in human nutrition. On average, cow's milk contains 3.5% protein. The most abundant proteins in bovine milk are caseins and some of the whey proteins, namely beta-lactoglobulin, alpha-lactalbumin, and serum albumin. A number of allelic variants and post-translationally modified forms of these proteins have been identified. Their occurrence varies with breed, individuality, stage of lactation, and health and nutritional status of the animal. It is therefore essential to have reliable methods of detection and quantitation of these proteins...
