Abstract

In Poland, food supplements have been popular among consumers for many years. Their sale brings producers huge profits. The interest in these products, especially in vitamin and mineral preparations and in immunity-supporting products increased dramatically due to the COVID-19 pandemic. Self-medication with untested dietary supplements may be health hazardous. Since in Poland and in other countries the procedures of quality control of food supplements are imperfect, this situation raises serious concerns about the risks of their unrestricted use and food fraud. The article briefly presents important problems in the safety of food supplements from the point of view of experts involved in their evaluation.

Abstract

Introduction: The use of dietary supplements has been increasing globally, especially among children. A lot of parents are influenced by advertising. In addition, in Poland a trend to self-medication has been observed. Parents often do not distinguish dietary supplements, medicinal products and non-prescription drugs. These are the most common reasons for the increase in sales of dietary supplements in Poland. Until a few years ago, many products containing vitamins and minerals intended for children were sold as medicines. Today, a product with the same formulation is sold as a dietary supplement. However, a few studies have been conducted to assess the use of dietary supplements among Polish children.

fenugreek (trigonella foenum-graecum l.), metabolic syndrome, fenugreek seeds, Plant culture, SB1-1110
Abstract

Fenugreek has a long tradition of use as a medicine and also has been commonly used as food in many countries. This plant is well known, especially in Asia. In Europe, fenugreek seeds are regarded as a traditional herbal medicine consumed in case of loss of appetite and in confirmed skin inflammations. Trigonella foenum-graecum seeds contain wide spectrum of different biologically active constituents which affect the properties of preparations produced from this plant. Numerous preclinical studies confirm the use of fenu-greek as a hypolipidemic and lowering blood glucose level drug. Unfortunately, there are not many clinical studies on fenugreek seeds in this area. Published studies often significantly differ in the amount and type of fenugreek seed preparation used. However, results of available scientific research are promising and suggest the possibility of using fenugreek seeds in metabolic syndrome therapy. Undoubtedly, further research is required to confirm such properties of Trigonella foenum-graecum.

pelargonium sidoides dc, root extract, clinical studies, children, food, Plant culture, SB1-1110
Abstract

Pelargonium sidoides DC is an interesting plant with various biological properties. Pharmaceutical companies and manufacturers of food supplements are particularly interested in its beneficial effects in upper respiratory tract infections. The search for new therapeutic options is especially important at a time when antibiotics are prescribed too often. However, due to proven clinical effects of extracts from Pelargonium sidoides, their use in diet supplements, especially intended for infants and small children, is highly disputable. The paper presents reports on the use of Pelargonium sidoides extracts in paediatrics and also tries to answer the question whether the pelargonium extract should be qualified as food supplement or medicine.

Abstract

A lot of products from food category specified in Regulation No. 609/2013 may contain herbal substances or their preparations. Definitions of food for infants and toddlers, food for special medical purposes, and total diet replacement for weight control are now clearly regulated by UE food legislation. The concept and definition of foodstuffs for particular nutritional published in Directive 2009/39/EC of the European Parliament and Council of 6 May 2009 do not apply. On 22 February 2019, Commission Delegated Regulation (EU) 2016/128 complementary to Regulation (EU) No. 609/2013, regarding specific compositional and information requirements for food of special medical purposes was applied. Novel foods and novel food ingredients are foods which have not been used for human consumption in UE to a significant degree before 15 May 1997.

Abstract

Food supplements are concentrated sources of nutrients and/or other substances with a nutritional or physiological effect. However, they often contain herbal substances or their preparations. Food supplements belong to category of food and for that reason are regulated by food legislation. European Union regulations and directives established general directions for dietary supplements, dietetic food, which due to their special composition or manufacturing process are prepared for specific groups of people with special nutritional needs, and novel food/novel food ingredients to ensure product safety, suitability and appropriate consumer information.

21. Competitive cAMP antagonists for cAMP-receptor proteins.

Author

Van Haastert, P J, Van Driel, R, Jastorff, B, Baraniak, J, Stec, W J, and De Wit, R J

Abstract

The two exocyclic oxygen atoms at phosphorus of cAMP have been replaced by a sulfur atom or by a dimethylamino group. These substitutions introduce chirality at the phosphorus atom; therefore, two diastereoisomers are known for each derivative: (SP)-cAMPS, (RP)-cAMPS, (SP)-cAMPN(CH3)2, and RP-cAMPN(CH3)2. We have investigated the agonistic and antagonistic activities of these compounds in four cAMP-dependent reactions: activation of the cellular slime mold Dictyostelium discoideum via its cell surface cAMP receptor, and phosphorylation by cAMP-dependent protein kinases type I, type II (both mammalian enzymes), and type D (derived from D. discoideum). The results show that 1) the compounds (SP)-cAMPS and (SP)-cAMPN(CH3)2 are (mostly full) agonists for the four proteins. Half-maximal activation is at micromolar concentrations (0.8-7 microM). 2) (RP)-cAMPS is a full antagonist for the cell surface receptor and protein kinases type I and II, with apparent inhibition constants between 0.8 and 8 microM. This compound is a partial agonist for protein kinase type D, where it induces maximally 50% activation of the enzyme if compared with cAMP. 3) (RP)-cAMPN(CH3)2 is a full antagonist for the cell surface receptor, and for protein kinase type II. This compound is a partial agonist for protein kinase type I (at least 50% activation if compared with cAMP), and inactive for protein kinase type D. This derivative is at least 25-fold less active as an antagonist than (RP)-cAMPS. 4) The activity of mixtures of different concentrations of the antagonist (RP)-cAMPS with different concentrations of cAMP reveals that the compound is a competitive antagonist of cAMP at micromolar concentrations.

22. A stereochemical investigation of the hydrolysis of cyclic AMP and the (Sp)-and (Rp)-diastereoisomers of adenosine cyclic 3′:5′-phosphorothioate by bovine heart and baker's-yeast cyclic AMP phosphodiesterases

Author

Abstract

Bovine heart cyclic AMP phosphodiesterase, which has a requirement for Mg2+, hydrolyses cyclic AMP with inversion of configuration at the phosphorus atom, but only the (Sp)-diastereoisomer of adenosine cyclic 3′:5′-phosphorothioate is hydrolysed by this enzyme. By contrast, the low-affinity yeast cyclic AMP phosphodiesterase, which contains tightly bound Zn2+, hydrolyses both the (Sp)- and the (Rp)-diastereoisomers of adenosine cyclic 3′:5′-phosphorothioate, the (Rp)-diastereoisomer being the preferred substrate under V max. conditions. Both of the diastereoisomers of adenosine cyclic 3′:5′-phosphorothioate, as well as cyclic AMP, are hydrolysed with inversion of configuration at the phosphorus atom by the yeast enzyme. It is proposed that, with both enzymes, the bivalent metal ion co-ordinates with the phosphate residue of the substrate, and that hydrolysis is catalysed by a direct ‘in-line’ mechanism.

23. Lysine 2,3-Aminomutase

Author

Baraniak, J, Moss, M L, and Frey, P A

Abstract

The conversion of L-lysine to L-β-lysine is catalyzed by lysine 2,3-aminomutase. The reaction involves the interchange of the 2-amino group of lysine with a hydrogen at carbon 3. As such the reaction is formally analogous to adenosylcobalamin-dependent rearrangements. However, the enzyme does not contain and is not activated by this coenzyme. Instead it contains iron and pyridoxal phosphate and is activated by S-adenosylmethionine. Earlier experiments implicated adenosyl-C-5′ of S-adenosylmethionine in the hydrogen transfer mechanism, apparently in a role similar or analogous to that of adenosyl moiety of adenosylcobalamin in the B12-dependent rearrangements. The question of whether both hydrogens or only one hydrogen at adenosyl-C-5′ participate in the hydrogen-transfer process has been addressed by carrying out the lysine 2,3-aminomutase reaction with S-[5′-3H] adenosylmethionine in the presence of 10 times its molar concentration of enzyme. Under these conditions allof the tritium appeared in lysine and β-lysine, showing that C-5′-hydrogens participate. To determine whether hydrogen transfer is compulsorily intermolecular and intramolecular, various molar ratios of [3,3-2H2]lysine and unlabeled lysine were submitted to the action of lysine 2,3-aminomutase under conditions in which 10–15% conversion to β-lysine occurred. Mass spectral analysis of the β-lysine for monodeutero and dideutero species showed conclusively that hydrogen transfer is both intramolecular and intermolecular. The results quantitatively support our postulate that activation of the enzyme involves a transformation of S-adenosylmethionine into a form that promotes the generation of an adenosyl-5′ free radical, which abstracts hydrogen from lysine to form 5′-deoxyadenosine as an intermediate.

24. Inhibition of cAMP-dependent protein kinase by adenosine cyclic 3‘-, 5‘-phosphorodithioate, a second cAMP antagonist.

Author

Botelho, L H, Webster, L C, Rothermel, J D, Baraniak, J, and Stec, W J

Abstract

A single sulfur substitution for either the axial or the equatorial exocyclic oxygen of adenosine cyclic 3', 5'-phosphate (cAMP) results in diastereometric phosphorothioate analogs of cAMP with agonist versus antagonist properties towards activation of cAMP-dependent protein kinase. Sulfur substitutions for both of the exocyclic oxygens of cAMP results in a dithioate analog of cAMP, adenosine cyclic 3', 5'-phosphorodithioate (cAMPS2), which has antagonist properties. cAMPS2 displaced [3H]cAMP from the binding sites on bovine heart Type II cAMP-dependent protein kinase as demonstrated by equilibrium dialysis experiments with an apparent Kd of 6.3 microM. The addition of 10, 30, or 100 microM cAMPS2 when measuring cAMP-induced activation of pure porcine heart Type II cAMP-dependent protein kinase resulted in a concentration-dependent increase in the amount of cAMP required to produce half-maximal activation (EC50). A plot of the EC50 values as a function of the cAMPS2 concentration resulted in a straight line from which a KI value of 4 microM was derived. cAMPS2 had no significant effect on the degree of cooperativity (n) of cAMP activation of the holoenzyme. These data suggest that the most important structural requirement for the dissociation of the holoenzyme is an equatorial exocyclic oxygen.

25. Inhibition of glycogenolysis in isolated rat hepatocytes by the Rp diastereomer of adenosine cyclic 3‘,5‘-phosphorothioate.

Author

Rothermel, J D, Stec, W J, Baraniak, J, Jastorff, B, and Botelho, L H

Abstract

The diastereomeric forms of adenosine cyclic 3‘,5‘-phosphorothioate, Rp cAMPS and Sp cAMPS, were studied in isolated hepatocytes from fed rats for their ability to interact with the intracellular cAMP-dependent protein kinase and to affect the phosphorylase kinase-phosphorylase glycogenolytic cascade. Incubation of the cells with increasing concentrations of Sp cAMPS produced a concentration-dependent activation of cAMP-dependent protein kinase with a concomitant increase in the glycogenolytic rate. Half-maximal and maximal velocities of glycogenolysis were reached at 8 X 10(-7) and 1 X 10(-5) M Sp cAMPS, respectively. Incubation of the cells with 10(-9) to 10(-4) M Rp cAMPS had no effect on basal glucose production or on cAMP-dependent protein kinase activity. Incubation of the cells simultaneously with 3 X 10(-6) M Sp cAMPS and increasing concentrations of Rp cAMPS produced half-maximal inhibition of glycogenolysis at 1 X 10(-5) M Rp cAMPS and maximal inhibition at 1 X 10(-4) M. The concentrations of Sp cAMPS required for half-maximal and maximal activation of glycogenolysis were increased 10-fold when 1 X 10(-5) M Rp cAMPS was present. These data imply that Sp cAMPS is a cAMP-agonist while Rp cAMPS is a cAMP-antagonist.

Abstract

Cyclic nucleotide derivatives have been used as a tool to investigate the existence of distinctive activating and hydrolytic sites on the phosphodiesterase from rat liver activated by cGMP (guanosine 3',5'-monophosphate). This positively cooperative enzyme was stimulated up to 30-fold by 3 microM cGMP when 3 microM cAMP (adenosine 3',5'-monophosphate) was used as substrate. All analogues were less potent activators than cGMP. Most cAMP derivatives were inactive, with two exceptions: 7-deazaadenosine 3',5'-monophosphate and 3'-amino-3'-deoxy-adenosine 3',5'-monophosphate. Benzimidazole ribonucleoside 3',5'-monophosphate, where the two atoms of nitrogen of the pyrimidine ring are missing was a better stimulator than the intact purine-related cyclic derivative. When cAMP and cGMP with identical chemical ligands substituted at the same position were compared, the cGMP analogue was always the more potent activator suggesting that the activating site is sensitive to a guanine-type cyclic nucleotide structure. Degradation of the derivatives by the enzyme was measured by high-performance liquid chromatography: no relation could be established between hydrolysis and effectiveness of activation. In addition, there was no parallelism between inhibitory and activating potency for ten cyclic nucleotide derivatives. Since the chemical interactions between the analogues at the activating site on the one hand and at the catalytic site on the other, are different, it is proposed that the sites are distinct. Consequently, it is suggested that the enzyme operates in steps. In the first activating step, cGMP is fixed by at least two hydrogen bonds at a specific binding site of the enzyme. This is followed by a conformational change of the protein and subsequently a change of the kinetic parameters. In a rather unspecific process and in a second hydrolytic step, several purine-related cyclic nucleotides are converted to the corresponding 5' nucleotides., Journal Article, Research Support, Non-U.S. Gov't, info:eu-repo/semantics/published

Abstract

The aim of the study was to investigate the effect of baicalein or Scutellaria baicalensis root extract interaction with methyldopa in pregnant spontaneously hypertensive rats (SHR) at the pharmacodynamic, molecular, and biochemical levels. The rats, after confirming pregnancy, received baicalein (200 mg/kg/day, p.o.) and extract (1000 mg/kg/day, p.o.), in combination with methyldopa (400 mg/kg/day; p.o.), for 14 consecutive days, 1 h before blood pressure and heart rate measurements. In the heart and placenta from mothers after giving birth to their offspring, mRNA expression of factors related to inflammatory processes (TNF-α, Il-1β, IL-6) and vascular diseases (TGF-β, HIF-1α, VEGF, PlGF) was measured. Levels of markers of oxidative stress (superoxide dismutase and malondialdehyde) in the placenta and indicators of myocardial damage (troponin cTnC and cTnI, creatine kinase, myoglobin, and lactate dehydrogenase) in the heart were also assessed. Baicalein co-administered with methyldopa was associated with reduced blood pressure, especially during the first three days. The interactions were more pronounced for such factors as TGF-β, HIF-1α, VEGF, and PlGF than TNF-α, Il-1β, and IL-6. Combined application of baicalein and extract with methyldopa may be of value in the development of a new antihypertensive medication intended for patients suffering from preeclampsia or pregnancy-induced hypertension.

46. Dandelion ( Taraxacum officinale L.) as a Source of Biologically Active Compounds Supporting the Therapy of Co-Existing Diseases in Metabolic Syndrome.

Author

Kania-Dobrowolska M and Baraniak J

Abstract

Nowadays, many people are struggling with obesity, type 2 diabetes, and atherosclerosis, which are called the scourge of the 21st century. These illnesses coexist in metabolic syndrome, which is not a separate disease entity because it includes several clinical conditions such as central (abdominal) obesity, elevated blood pressure, and disorders of carbohydrate and fat metabolism. Lifestyle is considered to have an impact on the development of metabolic syndrome. An unbalanced diet, the lack of sufficient physical activity, and genetic factors result in the development of type 2 diabetes and atherosclerosis, which significantly increase the risk of cardiovascular complications. The treatment of metabolic syndrome is aimed primarily at reducing the risk of the development of coexisting diseases, and the appropriate diet is the key factor in the treatment. Plant raw materials containing compounds that regulate lipid and carbohydrate metabolism in the human body are investigated. Dandelion ( Taraxacum officinale F.H. Wigg.) is a plant, the consumption of which affects the regulation of lipid and sugar metabolism. The growth of this plant is widely spread in Eurasia, both Americas, Africa, New Zealand, and Australia. The use and potential of this plant that is easily accessible in the world in contributing to the treatment of type 2 diabetes and atherosclerosis have been proved by many studies.

Abstract

Background and Objectives : We present a retrospective report on the cardio-hematological care of hematology patients at a university hospital in Poland during the COVID-19 pandemic. Materials and Methods : The number of hospitalizations at the Hematology Department and cardio-hematology consultations throughout 2019 and 2020 was analyzed. The types of cardiac procedures, risk factors, and complications were also assessed. Results : A significant reduction in the number of hospitalizations was observed in 2020 as compared to 2019. However, there were no significant differences in the incidence of hematological diseases between both of the analyzed years. In 2019, 299 cardiac consultations were performed in hematological patients, and there was a total of 352 such consultations performed in 2020 ( p = 0.042). Less high-risk tests (transesophageal and stress echocardiography) were performed in 2020, in favor of the use of cardiac computed tomography in cardiac diagnostics as it was safer during the pandemic. At least one cardiovascular risk factor during cardiac consultation was noted in 42% and 48% of hematological patients in 2019 and 2020, respectively. Among 651 examined hematological patients, the most common findings were mild cardiac complications of hemato-oncological treatment, which were found in 57 patients. Conclusions : This study seems to confirm that during a pandemic there is an increased demand for well-organized cardio-hematology consultations.

Abstract

The study was carried out on alcohol-preferring male Wistar rats. The following drugs were repeatedly (28×) administered: acamprosate (500 mg/kg, p.o.), naltrexone (0.1 mg/kg, i.p), and Pueraria lobata (kudzu) root extract (KU) (500 mg/kg, p.o.) and its isoflavones: daidzin (40 mg/kg, p.o.) and puerarin (150 mg/kg, p.o.). Their effects on a voluntary alcohol intake were assessed. KU and alcohol were also given for 9 days in an experiment on alcohol tolerance development. Finally, total and active ghrelin levels in peripheral blood serum were measured by ELISA method. Acamprosate, naltrexone, daidzin, and puerarin, reducing the alcohol intake, caused an increase in both forms of ghrelin levels. On the contrary, though KU inhibited the alcohol intake and alcohol tolerance development, it reduced ghrelin levels in alcohol-preferring rats. The changes of ghrelin concentration could play a role as an indicator of the currently used drugs. The other effect on the KU-induced shift in ghrelin levels in the presence of alcohol requires further detailed study.
