Tomas AM, van der Wel AM, Thomas AW, Janse CJ, Waters AP.
PMID: 17040769
Parasitol Today. 1998 Dec;14(6):245-9. doi: 10.1016/s0169-4758(98)01248-4.

Transfection of malaria parasites is a rapidly emerging technology that offers great promise for the investigation of many aspects of infection. Animal models of malaria have always played an important role in the investigation of the disease. In this...

A pea mutant for the study of hydrotropism in roots.

Science (New York, N.Y.)

Jaffe MJ, Takahashi H, Biro RL.
PMID: 17816077
Science. 1985 Oct 25;230(4724):445-7. doi: 10.1126/science.230.4724.445.

Plant roots grow in the direction of increasing soil moisture, but studies of hydrotropism have always been difficult to interpret because of the effect of gravity. In this study it was found that roots of the mutant pea ;Ageotropum'...

Cholinesterases from Plant Tissues: II. Inhibition of Bean Cholinesterase by 2-Isopropyl-4-dimethylamino-5-methylphenyl-1-piperidine Carboxylate Methyl Chloride (AMO-1618).

PMID: 16658537
Plant Physiol. 1973 Sep;52(3):233-5. doi: 10.1104/pp.52.3.233.

2-Isopropyl-4-dimethylamino-5-methylphenyl-1-piperidine carboxylate methyl chloride (AMO-1618) inhibits the activity of a cholinesterase isolated from mung bean (Phaseolus aureus) roots at concentrations comparable to those which retard growth and inhibit development of secondary roots of bean seedlings. Fifty per cent inhibition...

Cholinesterases from plant tissue: v. Cholinesterase is not pectin esterase.

Plant physiology

Fluck RA, Jaffe MJ.
PMID: 16658976
Plant Physiol. 1974 Nov;54(5):797-8. doi: 10.1104/pp.54.5.797.

Several properties of the cholinesterase from Phaseolus aureus Roxb. and of pectin (methyl) esterases from both Phaseolus aureus and Lycopersicon esculentum (L.) Mill. are contrasted. Cholinesterase activity is inhibited by all of the concentrations of NaCl tested, from 0.05...

Computer-Assisted Image Analysis of Tissues of Ethrel-Treated Pinus taeda Seedlings.

Plant physiology

Telewski FW, Wakefield AH, Jaffe MJ.
PMID: 16662955
Plant Physiol. 1983 May;72(1):177-81. doi: 10.1104/pp.72.1.177.

A microcomputer based video image analyzer is described and demonstrated in the analysis and comparison of tissue types of 6-month-old Ethrel-treated and control seedlings of loblolly pine (Pinus taeda L.). Two different programs were employed. ;Topographer I' sought, identified,...

Physiological Studies on Pea Tendrils: VI. The Characteristics of Sensory Perception and Transduction.

Plant physiology

Jaffe MJ.
PMID: 16657387
Plant Physiol. 1970 Jun;45(6):756-60. doi: 10.1104/pp.45.6.756.

Tendrils may be said to possess a sense of touch, and the direction and amplitude of the coiling response can be used to define the characteristics of this sense. These characteristics are, first, that the tendril will coil only...

Cholinesterases from Plant Tissues: III. Distribution and Subcellular Localization in Phaseolus aureus Roxb.

Plant physiology

Fluck RA, Jaffe MJ.
PMID: 16658783
Plant Physiol. 1974 May;53(5):752-8. doi: 10.1104/pp.53.5.752.

The distribution and localization of cholinesterase in Phaseolus aureus, Glycine max, and Pisum sativum is described. The enzyme is present in roots, leaves, stems, root callus tissue, root cells suspension cultures, and root nodules. Cholinesterase in roots is found...

Location, acid strength, and mobility of the acidic protons in Keggin 12-H3PW12O40: a combined solid-state NMR spectroscopy and DFT quantum chemical calculation study.

Journal of the American Chemical Society

Yang J, Janik MJ, Ma D, Zheng A, Zhang M, Neurock M, Davis RJ, Ye C, Deng F.
PMID: 16366582
J Am Chem Soc. 2005 Dec 28;127(51):18274-80. doi: 10.1021/ja055925z.

Solid-state 13C NMR experiments and quantum chemical Density Functional Theory (DFT) calculations of acetone adsorption were used to study the location of protons in anhydrous 12-tungstophosphoric acid (HPW), the mobility of the isolated and hydrated acidic protons, and the...

Retraction: An effective vaccine strategy protective against antigenically distinct tumor variants.

Cancer research

Pavelko KD, Hansen MJ, Pease LR, Heckman KL.
PMID: 21045159

Pt promotion and spill-over processes during deposition and desorption of upd-H(ad) and OH(ad) on Pt(x)Ru(1-x)/Ru(0001) surface alloys.

Physical chemistry chemical physics : PCCP

Hoster HE, Janik MJ, Neurock M, Behm RJ.
PMID: 20596565
Phys Chem Chem Phys. 2010 Sep 21;12(35):10388-97. doi: 10.1039/c003635h. Epub 2010 Jul 01.

The electrochemical adsorption of underpotential deposited hydrogen (upd-H(ad)) and OH(ad) on structurally well-defined Pt(x)Ru(1-x)/Ru(0001) surface alloys was investigated by cyclic voltammetry and density functional theory (DFT) calculations. The adsorption energies of both upd-H(ad) and OH(ad) decrease with increasing Pt...

Carbonate-H₂O₂ leaching for sequestering uranium from seawater.

Dalton transactions (Cambridge, England : 2003)

Pan HB, Liao W, Wai CM, Oyola Y, Janke CJ, Tian G, Rao L.

Dalton Trans. 2014 Jul 28;43(28):10713-8. doi: 10.1039/c3dt53404a.

Uranium adsorbed on amidoxime-based polyethylene fiber in simulated seawater can be quantitatively eluted at room temperature using 1 M Na2CO3 containing 0.1 M H2O2. This efficient elution process is probably due to the formation of an extremely stable uranyl-peroxo-carbonato...
