Free Amino Acids in Human Amniotic Fluid. a Quantitative Study by Ion-Exchange Chromatography
Pediat. Res. 3: 1 13-120 (1969) Amino acids fetus amniotic fluid pregnancy Free Amino Acids in Human Amniotic Fluid. A Quantitative Study by Ion-Exchange Chromatography HARVEYL. LEVY[^^] and PAULP. MONTAG Department of Neurology, Harvard Medical School; the Joseph P. Kennedy Jr. Memorial Laboratories, Massachusetts General Hospital, Boston, Massachusetts; and the Worcester Hahnemann Hospital, Worcester, Massachusetts, USA Extract Amniotic fluid was collected at inductive amniotomy or just prior to delivery following full-term uncomplicated pregnancies. Table I lists the means, ranges, and standard deviations for the concen- trations of amino acids obtained by ion-exchange chromatography of 16 specimens of amniotic fluid. Each specimen contained the following 22 amino acids: taurine, aspartic acid, threonine, serine, glutamine, proline, glutamic acid, citrulline, glycine, alanine, a-aminobutyric acid, valine, cystine, methionine, isoleucine, tyrosine, phenylalanine, ornithine, lysine, histidine, and arginine. In addition, tryptophan, which could not be detected by the ion-exchange chromatographic method employed, was found in each specimen by paper chromatography. The amino acids present in amniotic fluid were the same as those found in samples of maternal vein, umbilical artery, and umbilical vein serum (table 11). Comparisons were made in the concentrations of several amino acids among amniotic fluid, maternal serum, umbilical artery and vein serum, and perinatal urine (table 11).Taurine was present in considerably greater concentration in amniotic fluid than in maternal serum. This amino acid is also present in large quantities in umbilical artery and vein serum (table 11) and is by far the greatest single contributor to the total free amino acid pool in perinatal urine [I]. -
The Relationship Between Citrulline Accumulation and Salt Tolerance During the Vegetative Growth of Melon (Cucumis Melo L.)
The relationship between citrulline accumulation and salt tolerance during the vegetative growth of melon (Cucumis melo L.) H.Y. Dasgan1, S. Kusvuran1, K. Abak1, L. Leport2, F. Larher2, A. Bouchereau2 1Department of Horticulture, Agricultural Faculty, Cukurova University, Adana, Turkey 2Université de Rennes 1, Campus de Beaulieu, Agrocampus Rennes, Rennes Cedex, France ABSTRACT Citrulline has been recently shown to behave as a novel compatible solute in the Citrullus lanatus (Cucurbitaceae) growing under desert conditions. In the present study we have investigated some aspects of the relationship which might occur in leaves of melon seedlings, also known to produce citrulline, between the capacity to accumulate this ureido amino acid and salt tolerance. With this end in view, salt-induced changes at the citrulline level have been compared in two melon genotypes exhibiting contrasted abilities to withstand the damaging effects of high salinity. Progressive salinization of the growing solution occurred at 23 days after sowing. The final 250 mmol/l external NaCl concentration was reached within 5 days and further maintained for 16 days. In response to this treatment, it was found that the citrulline amount increased in fully expanded leaves of both genotypes according to different ki- netics. The salt tolerant genotype Midyat was induced to accumulate citrulline 4 days before the salt sensitive Yuva and as a consequence the final amount of this amino acid was twice higher in the former than in the latter. Compa- red with citrulline, the free proline level was found to be relatively low and the changes induced in response to the salt treatment exhibited different trends according to the genotypes under study. -

Marketing Research on Dietary Supplements for Periodontitis in Patient Diabetes
Original Study MARKETING RESEARCH ON DIETARY SUPPLEMENTS FOR PERIODONTITIS IN PATIENT DIABETES Galyna Biloklytska, Svitlana Viala, Alina Koval* National Medical Academy of Postgraduate Education named after P. L. Shupyk, Kyiv, Ukraine. ABSTRACT The vast majority of periodontal diseases are inflammatory and can develop under the influence of both local causes and the combined action of common (endogenous) and local factors against the background of changes in the reactivity of the body. In the pathogenesis of the development of periodontal diseases in patients with diabetes, the main role is given to angiopathies. Since periodontitis is characterized by various vascular disorders, which are largely similar to diabetic angiopathy, it is not easy to prove the presence of the latter with periodontitis. So some authors argue this, while, others deny it. The starting point of diabetic microangiopathies is a violation of carbohydrate metabolism, as well as a violation of glycosamine metabolism, which determines the functional and structural integrity of the vascular basement membrane. Key words: producing countries, periodontitis, diabetes mellitus, dietary supplements, medicines, dentistry. Introduction the treatment and prevention of such pathology, as periodontitis in patients with diabetes. Nowadays, the problem of treatment and rehabilitation of patients with periodontitis is quite actual, as there is an The search for modern drugs and perspective combinations increase in morbidity among people of working age, of microelements for treatment, both internally and locally, increasing demands on appearance as a factor that plays an using applications on periodontal tissues in patients with important role in professional and personal success in various types of diabetes, involves marketing analysis of society. -

CHURCHWARD-VENNE, B.A. (HONS); M.Sc. A Thesis Submitted to the School of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy McMaster University © Copyright by Tyler A. Churchward-Venne, 2013 DOCTOR OF PHILOSOPHY (2013) McMaster University (Kinesiology) Hamilton, Ontario TITLE: Nutritional and contractile regulation of human muscle protein synthesis: role of leucine and citrulline. AUTHOR: Tyler A. Churchward-Venne, B.A. (Hons) (York University); M.Sc. (The University of Western Ontario). SUPERVISOR: Dr. Stuart M. Phillips SUPERVISORY COMMITTEE: Dr. Martin J. Gibala Dr. Gianni Parise NUMBER OF PAGES: 203 ii ABSTRACT Amino acids are key nutritional stimuli that are both substrate for muscle protein synthesis (MPS), and signaling molecules that regulate the translational machinery. There is a dose-dependent relationship between protein intake and MPS that differs between young and elderly subjects. The current thesis contains results from three separate studies that were conducted to examine to potential to enhance smaller doses of protein, known to be suboptimal in their capacity to stimulate MPS, through supplementation with specific amino acids, namely leucine and citrulline. The first two studies examined the potential to enhance the muscle protein synthetic capacity of a smaller, suboptimal dose of whey protein with leucine. In study one, we concluded that leucine supplementation of a suboptimal dose of protein could render it as effective at enhancing rates of MPS as ~four times as much protein (25 g) under resting conditions, but not following resistance exercise. -

Furthermore, enterocyte, with either proline or glutamate as the dietary precursor. arginine supplementation was shown to reduce the incidence We have shown several times in piglets that proline is the only of all stages of NEC in moderately at risk infants (10) and a precursor to arginine, although in vitro evidence supports glutamate single bolus infusion of i.v. arginine improved oxygenation in in this role. Because of this uncertainty, we performed a multitracer infants with pulmonary hypertension (11). Therefore, because stable isotope study to determine whether proline, glutamate, or both are dietary precursors for arginine in enterally fed human neonates. arginine is clearly important for metabolism in the neonate, it Labeled arginine (M ϩ 2), proline (M ϩ 1), and glutamate (M ϩ 3) is critical to understand the metabolic pathways involved in its were given enterally to 15 stable, growing preterm infants (GA at synthesis.
