Stushnoff Department of Horticulture and Landscape Architecture, Colorado State University, Fort Collins, CO 80523-1173 DDITIONAL INDEX WORDS A . Buchloe dactyloides, cold hardiness, fructose, glucose, raffinose, sucrose, LT50 ABSTRACT. No information is available regarding endogenous soluble carbohydrate accumulation in buffalograss [Buchloe dactyloides (Nutt.) Engelm.] during cold acclimation. The objective of this study was to determine composition of soluble carbohydrates and their relationship to freezing tolerance in two buffalograss cultivars, 609 and NE 91-118, with different freezing tolerances. The experiment was conducted under natural cold acclimation conditions in two consecutive years in Fort Collins, Colo. Based upon average LT50 (subfreezing temperature resulting in 50% mortality) from seven sampling intervals in 1998–99 and six sampling intervals in 1999–2000, ‘NE 91-118’ survived 4.5 °C and 4.9 °C colder temperatures than ‘609’, during the 1998-1999 and 1999–2000 winter seasons, respectively. Glucose, fructose, sucrose, and raffinose were found in both cultivars in both years, and were generally higher in acclimated than pre- and post-acclimated stolons. Stachyose was not present in sufficient quantities for quantification. Cultivar NE 91-118 contained 63% to 77% more glucose and 41% to 51% more raffinose than ‘609’ in the 1998–99 and 1999–2000 winter seasons, respectively. In 1999–2000, fructose content in ‘NE 91-118’ was significantly higher than that of ‘609’. A significant negative correlation was found between LT50 vs. all carbohydrates in 1999–2000, and LT50 vs.

  • Differential Effects of the Poly (ADP-Ribose)Polymerase (PARP
    British Journal of Cancer (2001) 84(1), 106–112 © 2001 Cancer Research Campaign doi: 10.1054/ bjoc.2000.1555, available online at http://www.idealibrary.com on http://www.bjcancer.com Differential effects of the poly (ADP-ribose) polymerase (PARP) inhibitor NU1025 on topoisomerase I and II inhibitor cytotoxicity in L1210 cells in vitro KJ Bowman*, DR Newell, AH Calvert and NJ Curtin Cancer Research Unit, University of Newcastle upon Tyne Medical School, Framlington Place, Newcastle upon Tyne NE2 4HH, UK Summary The potent novel poly(ADP-ribose) polymerase (PARP) inhibitor, NU1025, enhances the cytotoxicity of DNA-methylating agents and ionizing radiation by inhibiting DNA repair. We report here an investigation of the role of PARP in the cellular responses to inhibitors of topoisomerase I and II using NU1025. The cytotoxicity of the topoisomerase I inhibitor, camptothecin, was increased 2.6-fold in L1210 cells by co-incubation with NU1025. Camptothecin-induced DNA strand breaks were also increased 2.5-fold by NU1025 and exposure to camptothecin-activated PARP. In contrast, NU1025 did not increase the DNA strand breakage or cytotoxicity caused by the topoisomerase II inhibitor etoposide. Exposure to etoposide did not activate PARP even at concentrations that caused significant levels of apoptosis. Taken together, these data suggest that potentiation of camptothecin cytotoxicity by NU1025 is a direct result of increased DNA strand breakage, and that activation of PARP by camptothecin-induced DNA damage contributes to its repair and consequently cell survival. However, in L1210 cells at least, it would appear that PARP is not involved in the cellular response to etoposide-mediated DNA damage.

Amis, Jwala Renukuntla, Pradeep Kumar Bolla and Bradley A. Clark * Department of Basic Pharmaceutical Sciences, Fred Wilson School of Pharmacy, High Point University, High Point, NC 27268, USA; [email protected] (T.M.A.); [email protected] (J.R.); [email protected] (P.K.B.) * Correspondence: [email protected]; Tel.: +1-336-841-9665 Received: 18 August 2020; Accepted: 16 September 2020; Published: 19 September 2020 Abstract: Cryoprotectants are often required in lyophilization to reduce or eliminate agglomeration of solute or suspended materials. The aim of this study was to select a cryoprotecting agent and optimize its concentration in a solid lipid nanoparticle formulation. Progesterone-loaded stearic acid solid lipid nanoparticles (SA-P SLNs) were prepared by hot homogenization with high speed mixing and sonication. The stearic acid content was 4.6% w/w and progesterone was 0.46% w/w of the initial formulation. Multiple surfactants were evaluated, and a lecithin and sodium taurocholate system was chosen. Three concentrations of surfactant were then evaluated, and a concentration of 2% w/w was chosen based on particle size, polydispersity, and zeta potential. Agglomeration of SA-P SLNs after lyophilization was observed as measured by increased particle size. Dextran, glycine, mannitol, polyvinylpyrrolidone (PVP), sorbitol, and trehalose were evaluated as cryoprotectants by both an initial freeze–thaw analysis and after lyophilization. Once selected as the cryoprotectant, trehalose was evaluated at 5%, 10%, 15%, and 20% for optimal concentration, with 20% trehalose being finally selected as the level of choice.

  • 2021 Code Changes Reference Guide
    Boston University Medical Group 2021 CPT Code Changes Reference Guide Page 1 of 51 Background Current Procedural Terminology (CPT) was created by the American Medical Association (AMA) in 1966. It is designed to be a means of effective and dependable communication among physicians, patients, and third-party payers. CPT provides a uniform coding scheme that accurately describes medical, surgical, and diagnostic services. CPT is used for public and private reimbursement systems; development of guidelines for medical care review; as a basis for local, regional, and national utilization comparisons; and medical education and research. CPT Category I codes describe procedures and services that are consistent with contemporary medical practice. Category I codes are five-digit numeric codes. CPT Category II codes facilitate data collection for certain services and test results that contribute to positive health outcomes and quality patient care. These codes are optional and used for performance management. They are alphanumeric five-digit codes with the alpha character F in the last position. CPT Category III codes represent emerging technologies. They are alphanumeric five-digit codes with the alpha character T in the last position. The CPT Editorial Panel, appointed by the AMA Board of Trustees, is responsible for maintaining and updating the CPT code set. Purpose The AMA makes annual updates to the CPT code set, effective January 1. These updates include deleted codes, revised codes, and new codes. It’s important for providers to understand the code changes and the impact those changes will have to systems, workflow, reimbursement, and RVUs. This document is meant to assist you with this by providing a summary of the changes; a detailed breakdown of this year’s CPT changes by specialty, and HCPCS Updates for your reference.

  • Sucrose/ Glucose
    www.megazyme.com RAFFINOSE/ SUCROSE/ GLUCOSE ASSAY PROCEDURE K-RAFGL 04/18 (120 Assays per Kit) © Megazyme 2018 INTRODUCTION: Grain legumes are an important component of both human and livestock diets. Galactosyl-sucrose oligosaccharides (raffinose, stachyose and verbascose) are major components in many food legumes,1 and the anti-nutritional activity of grain legumes is frequently associated with the presence of these oligosaccharides.2 Galactosyl-sucrose oligosaccharides are not hydrolysed in the upper gut due to the absence of α-galactosidase. In the lower intestine they are metabolised by bacterial action, producing methane, hydrogen and carbon dioxide, which lead to flatulence and diarrhoea. Galactosyl- sucrose oligosaccharides are thus a factor limiting the use of grain legumes in monogastric diets.3 Several solvents have been employed for the extraction of galactosyl- sucrose oligosaccharides from legume-seed flours. These are generally water/alcohol mixtures. Before (or concurrent with) extraction, it is vital that endogenous α-galactosidase and invertase are inactivated. This can be achieved by refluxing the flour in ethanol or in an aqueous ethanol mixture before the flour is subjected to aqueous extraction. Identification and quantification of the extracted galactosyl- sucrose oligosaccharides have been achieved using an array of chromatographic procedures, however many of these methods are, at best, semi-quantitative. Chromatographic procedures employing high performance liquid chromatography and low pressure liquid chromatography (using Bio-Gel P2) are quantitative, but can be time consuming, particularly in the area of sample preparation. It is well known that raffinose, stachyose and verbascose are hydrolysed by α-galactosidase to D-galactose and sucrose. Biochemical kits for the measurement of raffinose are commercially available.

The mobilities on SDS-gel electrophoresis and the NH2-terminal amino acids (arginine) of the two enzyme species were identical. The COOH- terminal amino acid sequence was found to be -Ser-Gly-Lys. The enzyme was inhibited by carbonyl, reducing and sulfhydryl reagents. The enzyme catalyzed the cross-dismutation reaction between formaldehyde and an aldehyde, such as propionaldehyde, acrolein, butyraldehyde, isobutyraldehyde and crotonaldehyde. The enzyme also catalyzed a coupled oxidoreduction between an alcohol and an aldehyde (RCH2OH+ R CHO^RCHO+R CH2OH) without addition of an electron acceptor. Aliphatic alcohols and aldehydes of C2 to C4 were utilized in this reaction. In the preceding study,1} we found an en- (E; formaldehyde dismutase, X; unknown zyme, which catalyzed dismutation of form- prosthetic group, and XH2; its reduced form.) aldehyde to form equimolar amounts of meth- Furthermore, we have found that the enzyme anol and formic acid, in Pseudomonas putida catalyzes a unique alcohol: aldehyde oxido- F61. The enzyme, given the trivial name of reduction reaction: formaldehyde dismutase, was purified and RCH2OH+R CHO >RCHO+R CH2OH partially characterized.
