Four experiments were conducted to characterize the interactions between fumaric (FA), malic (MA), or citric acid (CA) and NaHCO3. In two experiments, seven diets were formulated containing 2.5% FA, MA, and CA, with or without 2.3, 1.9, or 1.4% NaHCO3, respectively, as well as a control diet (no addition of organic acids or NaHCO3) for 28-d-old pigs (Exp. 1, corn-soy protein concentrate-based d...

Ingestion of sodium bicarbonate (NaHCO3) is known to enhance athletic performance, probably via increased extracellular buffering capacity. At present, little is known about the direct effects of NaHCO3 on myogenesis, especially in vitro. Here, we examined the effects of NaHCO3 and the combined effects of NaHCO3 and continuous mild heat stress (CMHS) at 39°C on the differentiation of human skel...

EVOLVING EVIDENCE supports that deviation from normal toward the acid spectrum of the acid-base balance is associated with premature death compared with patients with a normal acidbase status. Patients with nondialysis-dependent chronic kidney disease (CKD) and metabolic acidosis have increased mortality compared with CKD patients without metabolic acidosis (5, 9). Furthermore, the risk for mor...

In this research sodium bicarbonate (NaHCO3) was introduced to generate carbon dioxide gas (CO2) to the existing nitrogen gas (N2) of elastomeric foam, to lower thermal conductivity (K). Various loadings of NaHCO3 (0 to 60 phr) were added into the azodicarbonamide (AZC)-containing compound and its properties were then determined. Two vulcanization methods, i.e., hot air and infrared (IR), were ...

Two experiments were conducted to determine effects of sodium bicarbonate (NaHCO3) on nitrogen (N) balance, ruminal N metabolism and site and extent of nutrient digestion in sheep fed 75% concentrate diets. A 2 X 2 factorial arrangement of treatments was employed in both trials with experimental diets balanced for 10.5 or 12.0% crude protein and containing 0 or 3.5% NaHCO3. In experiment 1, 12 ...

Few studies have investigated the alkali-based salt resistance aspect of plants. Here, we used 2 pumpkin cultivars (‘Cucurbita ficifolia Bouch.’ and ‘Chuandilong’) to study the growth and physiological response mechanisms of pumpkin to different levels of NaHCO3 stress. After second true leaf development, pumpkin seedlings were treated with varying levels of NaHCO3 stress (0, 30, 60 and 90 mmol...

This investigation examined the effects of NaHCO3 loading on lactate concentration ([La]), acid-base balance, and performance for a 603. 5-m sprint task. Ten greyhounds completed a NaHCO3 (300 mg/kg body weight) and control trial in a crossover design. Results are expressed as means +/- SE. Presprint differences (P < 0.05) were found for NaHCO3 vs. control, respectively, for blood pH (7.47 +/- ...

Carbicarb is a mixture of Na2CO3/NaHCO3 that buffers similarly to NaHCO3, but without net generation of CO2. We studied the effects of carbicarb in an animal preparation of hypoxic lactic acidosis (HLA). HLA was induced by ventilating dogs with an hypoxic gas mixture (8% O2/92% N2). Dogs with HLA (n = 28) were then treated with 2.5 meq/kg of either NaHCO3 or carbicarb over 1 hr. Measurements we...

abstract in order to assess the availability of phosphorous (p), different methods have been proposed in the last decades. the results of these methods in soils with various ph, calcium carbonate, organic matter, al and fe oxides and hydroxides and other properties especially in iranian soils can not be used. in addition, knowledge about transformation of p forms is necessary for perception of ...
