1. Regulation of renal amino acid transporters during metabolic acidosis.
Match Strength: 6.504
The kidney plays a major role in acid-base homeostasis by adapting the excretion of acid equivalents to dietary intake and metabolism. Urinary acid excretion is mediated by the secretion of protons and titratable acids, particularly ammonia. NH(3) is synthesized in proximal tubule cells from glutamine taken up via specific amino acid transporters. We tested whether kidney amino acid transporters are regulated in mice in which metabolic acidosis was induced with NH(4)Cl. Blood gas and urine analysis confirmed metabolic acidosis. Real-time RT-PCR was performed to quantify the mRNAs of 16 amino ... Read More »

2. Optimizing rumen functions in the close-up transition period and early lactation to drive dry matter intake and energy balance in cows.
Match Strength: 6.038
The large deficit in energy intake in relation to energy requirements during the transition and early lactation periods means that high-producing cows need energy-dense rations. High-starch diets are intensively fermented by the microbial ecosystem in the rumen, giving rise to a high production of VFAs and resulting in a drop in pH and the accumulation of lactic acid, which exacerbates the decline in pH and is considered as the major cause of rumen acidosis. This rumen dysfunction affects rumen microbes and results in less efficient digestion, thereby decreasing feed intake and exacerbating ... Read More »

3. Erythrocytes with T-state-stabilized hemoglobin as a therapeutic tool for postischemic liver dysfunction.
Match Strength: 5.602
This study aimed to examine if T-state stabilization of hemoglobin in erythrocytes could protect against postischemic organ injury. Human erythrocytes containing three different states of Hb allostery were prepared: control Hb (hRBC), CO-Hb that is stabilized under R-state with the 6-coordinated prosthetic heme (CO-hRBC), and alpha-NO-deoxyHb stabilized under T-state (alpha-NO-hRBC). To prepare alpha-NO-RBC, deoxygenated RBC was treated with FK409, a thiol-free NO donor, at its half molar concentration to that of Hb; this procedure resulted in the 5-coordinated NO binding on the alpha-subunit ...

4. Key issues in advanced bleeding care in trauma.
Match Strength: 4.939
The incidence of hemostatic abnormalities in the early hours after traumatic incident is high and represents an independent predictor of mortality. Key factors in the development of traumatic coagulopathy include the severity of injury, hypothermia, acidosis, hemorrhagic shock, hemodilution, clotting factor consumption, and fibrinolysis. Assessment of bleeding includes evaluation of the mechanism of injury, vital signs, biochemistry, detection of external and internal bleeding sources, injuries found upon secondary investigation, and response to treatment. Priority in treating the bleeding ... Read More »

5. Volume Expansion with Albumin Compared to Gelofusine in Children with Severe Malaria: Results of a Controlled Trial.
Match Strength: 4.701
OBJECTIVES: Previous studies have shown that in children with severe malaria, resuscitation with albumin infusion results in a lower mortality than resuscitation with saline infusion. Whether the apparent benefit of albumin is due solely to its colloidal properties, and thus might also be achieved with other synthetic colloids, or due to the many other unique physiological properties of albumin is unknown. As albumin is costly and not readily available in Africa, examination of more affordable colloids is warranted. In order to inform the design of definitive phase III trials we compared ...

6. The immediate response to severe shock in a canine model with a combination of hypertonic-hyperoncotic solution with naloxone.
Match Strength: 4.333
To evaluate the acute hemodynamic and acid-base balance effects of hypertonic-hyperoncotic solution (HHS) combined with naloxone in the treatment of hemorrhagic shock in 45 male splenectomized adult mongrel dogs, a severe controlled hemorrhagic shock (20 mmHg mean arterial pressure during 30 min) was established in the groups (n=6) no treatment, shed blood reinfusion, hypertonic-hyperoncotic (saline-dextran) solution alone, naloxone alone (NX), or combination. Interventions included propiopromazine-pentobarbital anesthesia and installation of Swan-Ganz, femoral arterial, and urethral catheters ... Read More »

7. Renal tubular acidosis type 2 with Fanconi's syndrome, osteomalacia, osteoporosis, and secondary hyperaldosteronism in an adult consequent to vitamin D and calcium deficiency: effect of vitamin D and calcium citrate therapy.
Match Strength: 3.944
OBJECTIVE: To describe a unique example of renal tubular acidosis type 2 (RTA 2) in conjunction with Fanconi's syndrome and osteomalacia consequent to vitamin D and calcium deficiency in an adult without underlying gastrointestinal disease. METHODS: We review the clinical, hormonal, histomorphometric, and micro-computed tomographic findings and the response to therapy with vitamin D and calcium in our patient. RESULTS: On admission, a 33-year-old African American woman had the following laboratory findings: serum ionized calcium 3.8 mg/dL (0.95 mmol/L), venous pH 7.26, bicarbonate 20 mEq/L, ... Read More »

8. The effect of nutritional management of the dairy cow on reproductive efficiency.
Match Strength: 3.484
The cause of low fertility in dairy cows is multifactorial. Poor nutrition during the dry and early postpartum periods results in reduced glucose, insulin, insulin-like growth factor (IGF-I) and low LH pulse frequency with concomitant increases in beta-hydroxy butyrate, non-esterified fatty acids (NEFA) and triacylglycerol. Cows must mobilize large lipid, but also some protein reserves, with a consequent increased incidence of such metabolic disorders as hypocalcaemia, acidosis, ketosis, fatty liver and displaced abomasums. The occurrence of milk fever and ketosis affects uterine contractions, ... Read More »

9. Using physiological models and decision theory for selecting appropriate ventilator settings.
Match Strength: 3.213
OBJECTIVE: To present a decision support system for optimising mechanical ventilation in patients residing in the intensive care unit. METHODS: Mathematical models of oxygen transport, carbon dioxide transport and lung mechanics are combined with penalty functions describing clinical preference toward the goals and side-effects of mechanical ventilation in a decision theoretic approach. Penalties are quantified for risk of lung barotrauma, acidosis or alkalosis, oxygen toxicity or absorption atelectasis, and hypoxaemia. RESULTS: The system is presented with an example of its use in a post ... Read More »

DESIGN: Case report. SETTING: Pediatric cardiac intensive care unit of a tertiary care hospital. PATIENT: An 11-wk-old boy. INTERVENTIONS: Intratracheal instillation of 4 mL (100 mg) of surfactant (Survanta) per kilogram of body weight to treat profound and refractory hypoxia and hypercapnia despite high-ventilation pressures, high respiratory rate, and the use of nitric oxide ...

11. Effect of a metabolically created systemic acidosis on calcium homeostasis and the diurnal variation in urine pH in the non-lactating pregnant dairy cow.
Match Strength: 2.628
Reducing the dietary cation-anion difference (DCAD) has been shown to be an effective means of preventing parturient paresis in confinement systems where cows are offered a total mixed ration containing DCAD-reducing mineral compounds (anionic salts). Such a supplementation strategy is not possible in cows being group fed forages precalving, and little is known about the effect of supplementing these cows with large amounts of anionic salts twice daily.Eight non-lactating, pregnant Holstein-Friesian cows were allocated to two levels of DCAD (-20 and +18 meq/100 g DM) for 24 d, with an ...
