Platelet aggregation: Part II Some results from a new method of study.

Journal of clinical pathology

[No authors listed]
PMID: 16810986
J Clin Pathol. 1962 Sep;15(5):452-5. doi: 10.1136/jcp.15.5.452.

The light transmitted through a suspension of platelets increases if the platelets aggregate. A method derived from this observation has been used to study the kinetics of platelet aggregation. Aggregation is more rapid at 37 degrees C., with rapid...

Further observations on platelet aggregation induced by adenosine diphosphate thrombin and tri-ethyl tin.

Journal of clinical pathology

O'brien JR.
PMID: 16811008
J Clin Pathol. 1963 May;16(3):223-6. doi: 10.1136/jcp.16.3.223.

Aggregation induced by adenosine diphosphate is inhibited by adenosine as well as by adenosine mono- and triphosphate. Thrombin-induced aggregation is also inhibited by adenosine and the monophosphate, but the triphosphate at a similar concentration is not inhibitory. Aggregation induced...

Impaired platelet function in endotoxemic pigs analyzed by flow cytometry.

Platelets

Larsson A, Eriksson M, Lundahl T, Lundkvist K, Lindahl T.
PMID: 16793686
Platelets. 1998;9(2):115-9. doi: 10.1080/09537109876898.

Endotoxin or bacterial lipopolysaccharide (LPS) is a structural component of Gram-negative bacteria. It is believed to be the major pathogenic factor of Gram-negative sepsis, and may result in intravascular coagulation and in a shock syndrome that is characterized by...

Respiratory control: loss in mitochondria from diseased plants.

Science (New York, N.Y.)

Wheeler H, Hanchey PJ.
PMID: 17807297
Science. 1966 Dec 23;154(3756):1569-71. doi: 10.1126/science.154.3756.1569.

Mitochondria from healthy oat seedlings oxidized succinate with good respiratory control and high ratios of adenosine diphosphate to oxygen. After treatment with victorin, the pathotoxin responsible for symptoms of Victoria blight of oats, susceptible seedlings yielded mitochondria with little...

Level of photosynthetic intermediates in isolated spinach chloroplasts.

Plant physiology

Latzko E, Gibbs M.
PMID: 16657074
Plant Physiol. 1969 Mar;44(3):396-402. doi: 10.1104/pp.44.3.396.

The level of intermediates of the photosynthetic carbon cycle was measured in intact spinach chloroplasts in an attempt to determine the cause of the induction lag in CO(2) assimilation. In addition, transient changes in the level of the intermediates...

Assay methods for antihepatotoxic activity using peroxide-induced cytotoxicity in primary cultured hepatocytes1.

Planta medica

Kiso Y, Kato O, Hikino H.
PMID: 17340401
Planta Med. 1985 Feb;51(1):50-2. doi: 10.1055/s-2007-969391.

Conditions were investigated to devise IN VITRO assay methods for antihepatotoxic activity using peroxide-induced damage in primary cultured rat liver cells. Utilizing linoleic acid peroxide, benzoyl peroxide, cumene hydroperoxide and adenosine diphosphate/Fe (3+), satisfactory assay procedures were established. Some...

Freezing damage to isolated tomato fruit mitochondria as modified by cryoprotective agents and storage temperature.

Plant physiology

Dickinson DB, Misch MJ, Drury RE.
PMID: 16657434
Plant Physiol. 1970 Aug;46(2):200-3. doi: 10.1104/pp.46.2.200.

Isolated tomato (Lycopersicon esculentum var. Kc 146) fruit mitochondria could be stored successfully in the frozen state without a cryoprotective agent if the mitochondria were frozen quickly by immersion in liquid nitrogen and later thawed quickly at 30 C....

Regulation of the Amount of Starch in Plant Tissues by ADP Glucose Pyrophosphorylase.

Science (New York, N.Y.)

Stark DM, Timmerman KP, Barry GF, Preiss J, Kishore GM.
PMID: 17835129
Science. 1992 Oct 09;258(5080):287-92. doi: 10.1126/science.258.5080.287.

Starch, a major storage metabolite in plants, positively affects the agricultural yield of a number of crops. Its biosynthetic reactions use adenosine diphosphate glucose (ADPGlc) as a substrate; ADPGlc pyrophosphorylase, the enzyme involved in ADPGlc formation, is regulated by...

Anaerobic dormancy quantified in artemia embryos: a calorimetric test of the control mechanism.

Science (New York, N.Y.)

Hand SC, Gnaiger E.
PMID: 17769739
Science. 1988 Mar 18;239(4846):1425-7. doi: 10.1126/science.239.4846.1425.

Continuous measurement of heat dissipation from brine shrimp embryos during reversible transitions from aerobic development to anaerobic dormancy demonstrates a primary role for intracellular pH(pH(i))in this metabolic switching. Artificially elevating the depressed pH(i) during anoxia by adding ammonia markedly...

Comparison of the effects of policosanol and atorvastatin on lipid profile and platelet aggregation in patients with dyslipidaemia and type 2 diabetes mellitus.

Clinical drug investigation

Castaño G, Fernández L, Mas R, Illnait J, Mesa M, Fernández JC.
PMID: 17535079
Clin Drug Investig. 2003;23(10):639-50. doi: 10.2165/00044011-200323100-00003.

BACKGROUND: Diabetes mellitus and hypercholesterolaemia increase the risk for coronary heart disease, with type 2 diabetes mellitus being the most prevalent form of diabetes, frequently accompanied by dyslipidaemia. The main goal of dyslipidaemia control in nondiabetic and diabetic patients...

Energy-linked Adenosine Diphosphate Accumulation by Corn Mitochondria: II. Phosphate and Divalent Cation Requirement.

Plant physiology

Abou-Khalil S, Hanson JB.
PMID: 16660949
Plant Physiol. 1979 Aug;64(2):281-4. doi: 10.1104/pp.64.2.281.

The requirement for phosphate and Mg(2+) in energy-linked [(3)H] ADP accumulation by corn mitochondria has been studied. Arsenate will fully substitute for phosphate; sulfate partially substitutes; acetate, bicarbonate, and pyrophosphate are ineffective. Phosphate is also taken up by the...

Fluorometric determination of adenosine nucleotide derivatives as measures of the microfouling, detrital, and sedimentary microbial biomass and physiological status.

Applied and environmental microbiology

Davis WM, White DC.
PMID: 16345633

Adenosine, adenine, cyclic adenosine monophosphate (AMP), AMP, nicotinamide adenine dinucleotide, adenosine diphosphate, and adenosine triphosphate (ATP) were recovered quantitatively from aqueous portions of lipid extracts of microfouling, detrital, and sedimentary microbial communities. These could be detected quantitatively in the...
