Chlorin e6 is a tricarboxylic acid degradation product of chlorophyll a. Four chlorin e6 bis(amino acid) conjugates were regioselectively synthesized bearing two aspartate conjugates in the 13(1),17(3)- and 15(2),17(3)-positions, or at the 13(1),15(2)via an ethylene diamine linker. One additional conjugate bearing two different amino acids, lysine at 13(1)via an ethylene diamine linker and an a...

conclusions epidemiological and regional evaluation of mbl-producing p. aeruginosa through simple and inexpensive methods should be considered for effective treatment of carbapenem-resistant p. aeruginosa infections. results amongst all the p. aeruginosa isolates, 58.7% were resistant to imipenem while 31.8%, 13.5% and 74.4% were resistant to meropenem, doripenem and ertapenem, respectively. am...

background: milk fever in cattle, sheep and goats occurs  around the time of parturition and is caused by hypocalcemia. objectives: the aim of this study was to investigate the physiological effects of experimental hypocalcemia on electrocardiography, hematology and serum biochemical changes in markhoz goat breed. methods: ethylene diamine tetra- acetate solution 4.6% was intravenously infused ...

Summii1stary. Low concentrations of indole-3-acetic acid inhibit the growth of pea root sections by indticing the formation of the growth regtilator, ethylene gas. Ethylene is produced within 15 to 30 minutes after inidole-3-acetic acid is applied and roots begin to swell immediately after they are exposed to the gas. Carbon dioxide competitively inhibits ethylene action in roots, impedles thei...

The title compound, [Zn(C(8)H(6)N(5)O(2))(2)(H(2)O)(2)], was synthesized by hydro-thermal reaction of ZnBr(2) with 2-[5-(2-pyrid-yl)-2H-tetra-zol-2-yl]acetic acid. The Zn(II) atom lies on an inversion center in a distorted octa-hedral environment with two planar trans-related N,N'-chelating 2-[5-(2-pyrid-yl)-2H-tetra-zol-2-yl]acetic acid ligands in the equatorial plane and two water mol-ecules ...

The formation of DNA-strand breaks was studied in cultured human lung cells (A 549) subjected to iron, either in the form of iron(III) citrate or in combination with the metal chelators ethylene diamine tetra-acetic acid (EDTA), nitrilo triacetic acid (NTA), or 8-hydroxyquinoline (8HQ). After 15 min exposure to 5 microM iron(III) citrate or iron chelate, the cellular levels of iron were found t...

The most common types of blood protozoa in chickens are from the phylum Apicomplexa, including Plasmodium, Leucocytozoon and Haemoproteus. Blood protozoan diseases can cause decreased egg production, stunting death poultry farms. This study aims to identify calculate prevalence infection casted off laying sold at Wonokromo Market, Surabaya City. One hundred samples were taken by purposive sampl...

The growth-inhibiting effects of indole-3-acetic acid (IAA) at high concentration and the synthetic auxins 7-chloro-3-methyl-8-quinolinecarboxylic acid (quinmerac), 2-methoxy-3,6-dichlorobenzoic acid (dicamba), 4-amino-3,6, 6-trichloropicolinic acid (picloram), and naphthalene acetic acid, were investigated in cleavers (Galium aparine). When plants were root treated with 0.5 mM IAA, shoot epina...
