#1
Sang In Lee, In Ho Kim
The gastrointestinal tract (GIT) is critical for nutrient absorption and is an important barrier against harmful pathogens and antigens. Difructose anhydrides (DFA)-IVs are nondigestible disaccharides that enhance calcium and iron absorption by affecting the intestinal epithelial tissue. However, their effects on intestinal functions are not fully understood. In this study, we performed a feeding trial and found that dietary DFA-IVs improved growth performance, relative breast muscle and liver weight, and digestibility and blood calcium and iron concentrations in broilers...

BACKGROUND: The 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) together with parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF23) regulates calcium (Ca2+) and phosphate (Pi) homeostasis, 1,25(OH)2D3 synthesis is mediated by hydroxylases of the cytochrome P450 (Cyp) family. Vitamin D is first modified in the liver by the 25-hydroxylases CYP2R1 and CYP27A1 and further activated in the kidney by the 1α-hydroxylase CYP27B1, while the renal 24-hydroxylase CYP24A1 catalyzes the first step of its inactivation...

BACKGROUND: Alpha-1-antitrypsin (AAT) deficiency (AATD) of Z, Mmalton, Siiyama type is associated with liver storage of the mutant proteins and liver disease. The Z variant can be diagnosed on isoelectric focusing (IEF) while Mmalton and Siiyama may be missed or misdiagnosed with this technique. Therefore, molecular analysis is mandatory for their characterization. In particular, that holds true for the Mmalton variant as on IEF profile it resembles the wild M2 subtype. METHODS: This is a retrospective analysis involving review of medical records and of liver biopsy specimens from a series of Mmalton, Z and Siiyama Alpha-1-antitrypsin deficiency patients...

Mitochondria are the energy-producing organelles within a cell. Furthermore, mitochondria have a role in maintaining cellular homeostasis and proper calcium concentrations, building critical components of hormones and other signaling molecules, and controlling apoptosis. Structurally, mitochondria are unique because they have 2 membranes that allow for compartmentalization. The composition and molecular organization of these membranes are crucial to the maintenance and function of mitochondria. In this review, we first present a general overview of mitochondrial membrane biochemistry and biophysics followed by the role of different dietary saturated and unsaturated fatty acids in modulating mitochondrial membrane structure-function...

Ca2+ handling by mitochondria is a critical function regulating both physiological and pathophysiological processes in a broad spectrum of cells. The ability to accurately measure the influx and efflux of Ca2+ from mitochondria is important for determining the role of mitochondrial Ca2+ handling in these processes. In this report, we present two methods for the measurement of mitochondrial Ca2+ handling in both isolated mitochondria and cultured cells. We first detail a plate reader-based platform for measuring mitochondrial Ca2+ uptake using the Ca2+ sensitive dye calcium green-5N...

To address issues such as transportation and the time-consuming nature of tissue-engineered liver for use as an effective drug metabolism and toxicity testing model, "ready-to-use" cryogenic tissue-engineered liver needs to be studied. The research developed a cryogenic tissue-engineered liver slice (TELS), which comprised of HepG2 cells and calcium alginate gel. Cell viability and liver-specific functions were examined after different cryopreservation and recovery culture times. Then, cryogenic TELSs were used as a drug-testing model and treated with Gefitinib...

Severely burned patients who are morbidly obese have poor clinical outcomes with aggravated metabolic consequences, a higher incidence of multiple organ dysfunction/failure, and significantly increased morbidity and mortality. The underlying mechanisms of these adverse outcomes are essentially unknown. Since the liver is one of the central metabolic organs, we hypothesized that thermal injury in obese patients leads to substantially increased lipolysis, hepatic fat infiltration, resulting in profound hepatic cellular and organellar alterations, consequently causing liver damage and severely augmented metabolic dysfunction...

BACKGROUND: Vitamin K (VK) is a co-factor of the γ-glutamyl carboxylase that catalyzes the conversion of glutamate residues to γ-carboxyglutamate in VK-dependent proteins. The carboxylation reaction imparts the essential calcium-binding residues for the biological function of several proteins involved in the process of coagulation and bone metabolism. VK deficiency is frequently encountered in newborns and can lead to fatal hemorrhagic complications. This review describes and discusses the clinical application of VK deficiency testing...

Zinc content in blood plasma and brain tissue of rats was studied by analytic mass-spectrometry with inductively coupled plasma. In control (saline-treated animal) zinc content in plasma was 3.6±1.4 mg/ml, in the liver - 12.5±2.5 mg/mg, in the spleen - 10.9±4.1 mg/mg, in the brain - 8.7±3.0 mg/mg. After a single intraperitoneal injection of zinc donator acizolum (24 mg/kg) zinc content decreased in all examined tissues, especially in brain. After a course of sequential acizolum injections (seven administrations during two weeks) essential elevation of zinc content in blood plasma and tissues investigated was detected...

Previously we have demonstrated that stromal interacting molecule-1 (STIM1) was involved in ethanol induced liver injury. However, the exact pathogenic mechanism of STIM1 in alcoholic liver disease (ALD) is still unknown. We constructed plasmid vectors encoding short-hairpin RNA against STIM1 to investigate its role in ALD in the rat liver cell line BRL and in Sprague-Dawley rats. The results showed that STIM1 targeted sh-RNA (Sh-STIM1) significantly ameliorated ethanol-induced BRL cells injury and liver injury in rats with 20 weeks-induced alcoholic liver disease...

Arsenic trioxide (As2 O3 ) is a promising new regimen for the treatment of acute promyelocytic leukemia (APL). The induction of oxidative stress mediated by reactive oxygen species (ROS) and excessive intracellular calcium influx are the main reasons behind As2 O3 toxicity. Since liver is the major organ for xenobiotic metabolism, it is always under stress. Antioxidant vitamins such as L-Ascorbic acid (L-AA) and α-Tocopherol (α-TOC) have been proposed to have beneficial effects against a variety of pathological conditions and are known by their free radical scavenging properties...

Hypercalcemia can be hazardous during pregnancy, most cases being due to primary hyperparathyroidism. We report a case of hypercalcemia with suppressed PTH levels necessitating treatment with bisphosphonates during pregnancy. A 38-year-old woman at the 26th week gestation was admitted because of symptomatic hypercalcemia. She did not take any medication that could influence her calcium levels. Physical examination was unremarkable. Laboratory tests on admission were: calcium 12.7 mg/dL (8.5-10.5 mg/dL), phosphorus 1...

Point-of-care ultrasound (POCUS) in the diagnoses of postoperative complications is discussed. POCUS is useful in many situations such as abdominal distension, elevated liver enzymes, abdominal pain, and fever, which are the common complications encountered after surgical operations. In the patients with abdominal distention, bowel distention or ascites can be easily detected by POCUS. Occasionally, congestive liver and milk of calcium bile caused by the administration of antibiotics cause elevated liver enzymes, and both of these can also be detected by POCUS...

Formation water (FoW) is a by-product from oil and gas production and usually has high concentrations of soluble salts and metals. Calcium (Ca) and magnesium (Mg) have been shown to reduce the toxicity of metals to aquatic animals, and previous study showed that high waterborne Ca exerts mild effect against disturbances on Na+ regulation in Amazonian armored catfish tamoatá (Hoplosternum littorale) acutely exposed to high Fe, Mn, and Ba levels. Here, we hypothesized that high Mg levels might also reduce the toxic effects of these metals on Na+ regulation of tamoatá...
