In the title compound, {[Mn(C(4)H(4)O(6))(H(2)O)]·H(2)O}(n), the Mn(2+) ion is connected to three different tartrate anions and a water mol-ecule, resulting in a distorted MnO(6) octa-hedral geometry. There are two tartrate half-anions in the asymmetric unit, both of which are completed by crystallographic twofold rotation symmetry. The tartrate dianions bridge the Mn(2+) ions to form a wave-li...

Turtles and other reptiles have long been recognized as a source of human Salmonella infections. To prevent turtle-associated Salmonella infections in humans, the sale and distribution of small turtles (i.e., those with a carapace length of less than 4 inches) has been prohibited in the United States since 1975. Despite this prohibition, small turtles remain available to the public from various...

We studied the optimal composition of EDTA-chelated biuret reagent for the determination of protein in serum. A reagent containing 18 mmol of EDTA, 15 mmol of Cu2, and 1 mol of NaOH per liter exhibits a very low blankbut about the same sensitivity as tartrate-chelated reagents. Maximum color intensity is attained within 25 mm at room temperature, and adheres to Beer’s law up to 120 g of protein...

Acid phosphatase levels in pure lymphocytes from normal individuals were determined cytochemically on intact cells and spectrophotometrically on cell extracts. Good correlation was demonstrated between the results obtained with both methods. Biochemical assay showed that a normal range of 7.2 +/- 0.9 and 7.1 +/- 1.0 mMoles per 10(6) lymphocytes was obtained without and with tartrate inhibition,...

BACKGROUND The diastereoselectivity of a vinylogous Mukaiyama aldol reaction of a series of N-substituted 4-oxy-2-trimethylsilyloxypyrroles with a tartrate-based aldehyde has been explored as a model reaction for castanospermine synthesis. RESULTS The study has revealed that the reaction is sensitive to the nature of the combination of N- and 4-oxy substituents. With a N-PMB or N-Bn and 4-met...

The asymmetric unit of the anhydrous title compound, 2Na(+)·C(4)H(4)O(6) (2-), contains two sodium cations and one tartrate anion. Each sodium ion is six coordinate, with bonding to six O atoms from both the carboxyl-ate and hydroxyl groups of the anion. A three-dimensional coordination network is formed with sodium ions stacking in layers along the c-axis direction. This network is supported b...

We describe a simple and rapid method for measuring catecholamine metabolites in urine collected on filter paper. By this method, "high-performance" liquid chromatography, urinary vanillylmandelic acid and homovanillic acid can be measured within 15 min after being eluted from filter paper treated with tartrate buffer. One hundred urine samples can be pretreated within 2 h and 100-120 samples a...

By decoupling the mechanical behaviour of building units for the first time in a wine-rack framework containing two different strut types, we show that lithium l-tartrate exhibits NLC with a maximum value, Kmax = -21 TPa-1, and an overall NLC capacity, χNLC = 5.1%, that are comparable to the most exceptional materials to date. Furthermore, the contributions from molecular strut compression and ...
