Opis:
The article analyses the vodka names containing numbers written in words or digits. The numerical names have long been used by naming specialists as a successful marketing trick. Combining words or letters with digits results in creating interesting names that not only arouse curiosity but also are easily remembered or written down. This is particularly important nowadays, when we are given the fast growing number of chrematonyms. The names with number components are also a source of information about the product, describing its characteristics or even some technological details in a more interesting way than it is done in traditional names. What is more, thanks to such names, invoking cultural, historical or geographical aspects, the product can be associated with a particular region, thus influencing the consumer’s decision. The article also examines the names with the measure components.

Opis:
This study was undertaken to evaluate whether a link exists between the activation of protein kinase C (PKC), operation of Na+/H+ exchanger (NHE), cell swelling and serotonin (5-HT) secretion in porcine platelets. Activation of platelets by thrombin or phorbol 12-myristate 13-acetate (PMA), a PKC activator, initiated a rapid rise in the activity of Na+/H+ exchanger and secretion of 5-HT. Both thrombin- and PMA-evoked activation of Na+/H+ exchanger was less pronounced in the presence of ethyl-isopropyl-amiloride (EIPA), an NHE inhibitor, and by GF 109203X, a PKC inhibitor. Monensin (simulating the action of NHE) caused a dose-dependent release of 5-HT that was not abolished by GF 109203X or EGTA. Lack of Na+ in the suspending medium reduced thrombin-, PMA-, and monensin-evoked 5-HT secretion. GF 109203X nearly completely inhibited 5-HT release induced by PMA-, partly that induced by thrombin, and had no effect on 5-HT release induced by monensin. EIPA partly inhibited 5-HT release induced by thrombin and nearly totally that evoked by PMA. Electronic cell sizing measurements showed an increase in mean platelet volume upon treatment of cells with monensin, PMA or thrombin. The PMA- and thrombin-evoked rise in mean platelet volume was strongly reduced in the presence of EIPA. As judged by optical swelling assay monensin and PMA produced a rapid rise in platelet volume. The swelling elicited by PMA was inhibited by EIPA and its kinetics was similar to that observed in the presence of monensin. Hypoosmotically evoked platelet swelling did not affect platelet aggregation but significantly potentiated thrombin-evoked release of 5-HT and ATP. Taken together, these results show that in porcine platelets PKC may promote 5-HT secretion through the activation of NHE. It is hypothesized that enhanced Na+/H+ antiport may result in a rise in cell membrane tension (due to cell swelling) which in turn facilitates fusion of secretory granules with the plasma membrane leading to 5-HT secretion.

Opis:
This study was undertaken to determine whether nitric oxide (NO) can affect platelet responses through the inhibition of energy production. It was found that NO donors: S-nitroso-N-acetylpenicyllamine, SNAP, (5-50 μM) and sodium nitroprusside, SNP, (5-100 μM) inhibited collagen- and ADP-induced aggregation of porcine platelets. The corresponding IC50 values for SNAP and SNP varied from 5 to 30 μM and from 9 to 75 μM, respectively. Collagen- and thrombin-induced platelet secretion was inhibited by SNAP (IC50 = 50 μM) and by SNP (IC50 = 100 μM). SNAP (20-100 μM), SNP (10-200 μM) and collagen (20 μg/ml) stimulated glycolysis in intact platelets. The degree of glycolysis stimulation exerted by NO donors was similar to that produced by respiratory chain inhibitors (cyanide and antimycin A) or uncouplers (2,4-dinitrophenol). Neither the NO donors nor the respiratory chain blockers affected glycolysis in platelet homogenate. SNAP (20-100 μM) and SNP (50-200 μM) inhibited oxygen consumption by platelets. The effect of SNP and SNAP on glycolysis and respiration was not reduced by 1H-[1,2,4]oxadiazolo-[4,3-a]quinoxalin-1-one, a selective inhibitor of NO-stimulated guanylate cyclase. SNAP (5-100 μM) and SNP (10-300 μM) inhibited the activity of platelet cytochrome oxidase and had no effect on NADH:ubiquinone oxidoreductase and succinate dehydrogenase. Blocking of the mitochondrial energy production by antimycin A slightly affected collagen-evoked aggregation and strongly inhibited platelet secretion. The results indicate that: 1) in porcine platelets NO is able to diminish mitochondrial energy production through the inhibition of cytochrome oxidase, 2) the inhibitory effect of NO on platelet secretion (but not aggregation) can be attributed to the reduction of mitochondrial energy production.

Opis:
Desmopressin (DDAVP) action on platelets is associated with the development of procoagulant response but the underlying mechanism of this phenomenon is not known. We investigated whether this effect of DDAVP might be due to activation of plasma membrane Na+/H+ exchanger. The DDAVP-induced platelet procoagulant response, measured as phospholipid-dependent thrombin generation, was dose dependent and significantly weaker than that produced by collagen or monensin (mimics Na+/H+ antiport). Both the DDAVP- and collagen-produced procoagulant responses were less pronounced in the presence of EIPA, an Na+/H+ exchanger inhibitor. Flow cytometry studies revealed that in vitro treatment of platelets with DDAVP or collagen was associated with the appearance of both degranulated (and fragmented) and swollen cells. The DDAVP-evoked rise in size and granularity heterogeneity was similar to that produced by collagen or monensin and was not observed in the presence of EIPA. Using flow cytometry and annexin V-FITC as a probe for phosphatidylserine (PS) we demonstrated increased and uniform binding of this marker to all subsets of DDAVP-treated platelet population. The DDAVP-evoked PS expression was dose dependent, strongly reduced by EIPA and weaker than that caused by monensin or collagen. As judged by optical swelling assay, DDAVP in a dose dependent manner produced a rise in platelet volume. The swelling was inhibited by EIPA and its kinetics was similar to that observed in the presence of monensin. Electronic cell-sizing measurements showed an increase in mean platelet volume and a decrease in platelet count and platelet crit upon treatment with DDAVP. DDAVP elicited a slow (much slower than collagen) alkalinization of platelet cytosol. Altogether the data indicate an involvement of Na+/H+ exchanger in the generation of procoagulant activity in DDAVP-treated platelets.

Opis:
ε-Aminocaproic acid (EACA) is a synthetic low molecular drug with antifibrinolytic activity. However, treatment with this drug can be incidentally associated with an increased thrombotic tendency. The aim of the present work was to test synthetic EACA derivatives for their antiplatelet activities. We investigated the effect of three EACA derivatives with antifibrinolytic activity: I. ε-aminocaproyl-L-leucine hydrochloride (HClH-EACA-L-Leu-OH), II. ε-aminocaproyl-L-(S-benzyl)-cysteine hydrochloride (HClH-EACA-L-Cys(S-Bzl)-OH) and III. ε-aminocaproyl-L-norleucine (H-EACA-L-Nle-OH) on platelet responses (aggregation and adhesion) and on their integrity. It was found that: 1. as judged by LDH release test, none of the tested compounds, up to 20 mM, was toxic to platelets, 2. in comparison with EACA, all the synthetic derivatives inhibited much stronger the ADP- and collagen-induced aggregation of platelets suspended in plasma (platelet rich plasma) and aggregation of these cells in whole blood, 3. EACA and its derivatives exerted a similar inhibitory effect on the thrombin-induced adhesion of platelets to fibrinogen-coated surfaces. Since platelet activation and blood coagulation are tightly associated processes, the antiplatelet properties of EACA derivatives are expected to indicate reduced thrombotic properties of these derivatives compared to EACA.

Opis:
In circulation, platelets may come into contact with both exogenous (cardiac glycoside treatment) and endogenously produced inhibitors of Na+/K+-ATPase. We examined whether blocking of platelet Na+/K+-ATPase by ouabain results in generation of procoagulant activity. It was shown that an in vitro treatment of platelets with ouabain (20-200 µM for 20 to 60 min) is associated with an intracellular accumulation of sodium ([Na+]i), generation of a weak calcium signal, and expression of procoagulant activity. The ouabain-induced procoagulant response was dose- and time-related, less pronounced than that evoked by collagen and similar to that produced by gramicidin, not affected by EDTA or aspirin, and strongly reduced in the absence of extracellular Na+ or by hyperosmolality. Flow cytometry studies revealed that ouabain treatment results in a unimodal left shift in the forward and side scatter of the entire platelet population indicating morphological changes of the plasma membrane. The shift was dose related, weaker than that evoked by collagen and similar to that produced by gramicidin. Ouabain-treated platelets express phosphatidylserine (PS). The ouabain-evoked PS expression was dose- and time-dependent, weaker than that produced by collagen and similar to that evoked by gramicidin. Electronic cell sizing measurements showed a dose-dependent increase in mean platelet volume upon treatment with ouabain. Hypoosmotically-evoked platelet swelling resulted in the appearance of procoagulant activity. Thromboelastography measurements indicate that, in whole blood, nanomolar (50-1000 nM, 15 min) concentrations of ouabain significantly accelerate the rate of clot formation initiated by contact and high extracellular concentration of calcium. We conclude that inefficiently operating platelet Na+/K+-ATPase results in a rise in [Na+]i. An increase in [Na+]i and the swelling associated with it may produce PS exposure and a rise in membrane curvature leading to the generation of a procoagulant activity.
