Opis:: Sida hermaphrodita as a crop plant could be used as raw material for the production of forage. The aim of this study was to evaluate the overall nutritional value of fresh and ensiled biomass of Sida hermaphrodita, harvested in the bud formation stage. The chemical and amino acid composition, fatty acid profile, concentrations of minerals and polyphenols of herbage and silage were determined. Additionally fermentation products were assessed in silage. Herbage contained crude protein (CP) of 182 g kg-1 dry matter (DM), neutral detergent fiber (NDF) of 375 g kg-1 DM and lignin content in NDF (L/NDF) was 8.88. Nitrogen fractions changed as a result of ensiling (P<0.010), non-protein nitrogen (NPN) from 274 g kg-1 total nitrogen (TN) in herbage to 683 g kg-1 TN in silage, and neutral detergent-insoluble nitrogen (NDIN) from 74.6 g kg-1 TN in herbage to 79.5 g kg-1 TN in silage. Silage was characterized by intensive lactic fermentation (114 g kg-1 DM) and pH of 4.30. It contained CP of 176 g kg-1 DM, NDF of 378 g kg-1 DM, and L/NDF (11.3) was higher than in the herbage. The CP of Sida hermaphrodita silage had a high content of essential amino acids (AAs) Lys, Thr, Val, Leu and Phe (3.98, 4.19, 4.55, 7.14 and 4.00 g 100 g-1 CP, respectively). Sida hermaphrodita silage was characterized by the highest K (6.262 g kg-1DM) content among macronutrients, and the highest content of Fe (40.88 mg kg-1 DM) and Mn (33.01 mg kg-1 DM) among micronutrients. Polyunsaturated fatty acids (PUFAs) predominated in the ether extract herbage and silage, and their proportion was three-fold and seven-fold higher than the proportion of monounsaturated fatty acids (MUFAs), respectively. Herbage had high quercetin content (652 µg g-1 DM), which decreased by 45% during the ensiling. Changes in the chemical composition suggest that this crop plant can be preserved by ensiling. The results of this study indicate that Sida hermaphrodita can be used for producing high-quality silage for ruminants.

Opis:: A field experiment was carried out in 2008−2010 at the Agricultural Experimental Farm of the University of Natural Sciences and Humanities in Siedlce, located in Zawady. The experiment was established on light loamy soil which belonged to a very good rye complex. The experiment was designed in a two-factor split-plot pattern with three replicates. The factors examined in the experiment included three cultivars of edible potatoes: Cekin, Satina, Tajfun, and five weed control methods: application of the following herbicides (mixed or alone) Command 480 EC, Command 480 EC and Dispersive Afalon 450 SC, Stomp 400 SC, Stomp 400 SC and Dispersive Afalon 450 SC, while the control consisted of mechanical weeding without chemical protection. The aim was to determine the influence of selected herbicides and their combinations (Command 480 EC, Command 480 EC and Dispersive Afalon 450 SC, Stomp 400 SC, Stomp 400 SC and Dispersive Afalon 450 SC) on the content of copper, zinc and manganese in three potato cultivars. Potato tubers were harvested at full maturity. Samples of potato tubers for chemical analyses were taken from plots during harvest. Microelements in the dry matter of potato tubers were determined by the AAS method. The content of copper was significantly dependent on the cultivars, weed control methods and weather conditions during the growing season. In contrast, concentrations of depended on the cultivars and meteorological conditions, whereas the content of manganese in potato tubers was strongly conditioned by genetic traits of the cultivars.

Opis:: One of the major functions of magnesium is the maintenance of proper electric potential of neurons. Pathological conditions associated with systemic magnesium deficiencies may be associated with disturbance of numerous neurophysiological processes. These may include neuron function, transmission of nerve impulses, neuromuscular transmission, muscle contraction and vasomotor reflex. Therefore, magnesium deficiencies, particularly those associated with hypomagnesemia, are a source of problems for neurologists. Migraine is one of the most common neurological disorders. Despite many years of research, pathophysiology of migraine has not been elucidated. The predominant opinion is that the onset of migraine headaches is associated with cerebral vascular spasms. Based on the available knowledge of biological functions of magnesium, at least several feasible mechanisms for prevention or reduction of the intensity of migraine attacks by magnesium ions have been proposed. The goal of this review is to summarize the literature reports on magnesium in the pathogenesis of migraine and to identify the potential uses for magnesium compounds in prevention and treatment of migraine headaches.
Jedną z najważniejszych funkcji magnezu jest utrzymywanie odpowiedniego potencjału elektrycznego komórek nerwowych. W stanach patologii związanych z ogólnoustrojowymi niedoborami magnezu może dochodzić do zakłócenia rozmaitych procesów neurofizjologicznych. Należą do nich m.in.: funkcjonowanie neuronów, przewodzenie impulsu nerwowego, przekaźnictwo nerwowo-mięśniowe i skurcz mięśni oraz odruch wazomotoryczny. Z powyższych względów stany niedoborów magnezu, zwłaszcza te przebiegające z hipomagnezemi ą, stały się problemem w praktyce klinicznej lekarza neurologa. Migrena jest jednym z najczęściej występujących schorzeń neurologicznych. Pomimo wielu lat badań, jej patofizjologia nie została jednoznacznie wyjaśniona. Aktualnie dominuje pogląd, iż pojawianie się migrenowych bólów głowy ma związek ze skurczem naczyń mózgowych. Na podstawie dostępnej wiedzy dotyczącej biologicznych funkcji magnezu zasugerowano istnienie przynajmniej kilku możliwych mechanizmów, za których pośrednictwem jony magnezu mogłyby zapobiegać pojawianiu się ataków migreny lub ograniczać ich nasilenie. Celem pracy było podsumowanie dostępnych w piśmiennictwie doniesień dotyczących roli magnezu w patogenezie migreny, a także wskazanie możliwości wykorzystania preparatów magnezu w profilaktyce i leczeniu migrenowych bólów głowy.

Opis:: Immunosuppressive therapy is necessary to prevent transplant rejection, also in the case of pregnant transplant recipients, which means that the medications may influence foetal development. An ideal immunosuppressive regimen should provide for excellent immunosuppression with minimal or no side effects. Yet, current immunosuppressive therapy regimens commonly used in clinical applications fail to meet this criterion. One of the complications caused by immunosuppressive drugs are mineralisation disorders in hard tissues. Therefore, in this study, we evaluated the impact of three regimens of immunosuppressive therapy used after renal transplantation, containing medications which are indicated (prednisone, cyclosporine A (CsA), tacrolimus (Tc)) and contraindicated (mycophenolate mofetil (MMF), everolimus) during pregnancy on the concentrations of essential minerals, calcium (Ca), phosphorus (P) and magnesium (Mg), affecting normal bone formation. The samples were analysed using inductively coupled plasma optical emission spectrometry (ICP-OES, ICAP 7400 Duo, Thermo Scientific) equipped with a concentric nebuliser and a cyclonic spray chamber. The immunosuppressive regimens under study had no effect on the levels of Mg and P, but they did contribute to increased bone Ca levels in the mothers in the group receiving Tc, MMF and prednisone and group receiving CsA, everolimus and prednisone. In the offspring of tested mother rats, immunosuppressive therapies may affect Mg levels in hard tissues. The immunosuppressive regimens administered at therapeutic doses are harmful to rat foetuses as evidenced by the small number or lack of offspring in the tested groups.

Opis:: The permissible threshold level of lead in blood (Pb-B) is currently established at 5 mg dL-1, but evidence suggests that it is impossible to determine the safety threshold for lead (Pb) and any exposure, especially in children, must be considered as potentially harmful. Methods used to reduce the concentration of Pb in blood (e.g. EDTA, penicillamine) are not always effective and are associated with serious side effects. One of the proposed dietary supplements in the case of exposure to Pb and low blood Pb concentrations is zinc (Zn), but the published literature on its effectiveness is limited. Therefore, the aim of this study was to clarify whether Zn supplementation may help reduce the concentration of Pb in the blood and tissues of rats, at the Pb-B level previously recognized as safe. Tests were performed on 6-8 week old male Wistar rats. Rats were divided into control and experimental groups: Group C – rats receiving drinking water ad libitum for 4 weeks; Group Pb – rats receiving Pb acetate 0.1% (PbAc) in drinking water ad libitum for 4 weeks; Group Zn – rats receiving ZnCO3 300 mg kg-1 diet for 4 weeks; Group Pb+Zn – rats receiving PbAc in drinking water ad libitum plus 300 mg ZnCO3 kg-1 diet for 4 weeks. The applied dose of 300 mg of ZnCO3 kg-1 diet results in a high but non-toxic Zn level. The concentrations of Pb and Zn in blood, plasma, liver and bone were determined by emission spectrometry in inductively coupled argon plasma (ICP OES). Incidental exposure of adult rats to Pb at doses resulting in the level of Pb in blood below the previously recognized as safe one caused: (i) increased Pb concentration in the bones and plasma and its reduction in the whole blood and liver (ii) simultaneous supplementation of rats exposed to Pb with a high but non-toxic dose of zinc did not result in the reduction of the Pb concentration in the blood and tissues of rats, nor did it induce any changes in the distribution of Pb in the examined tissues (iii) supplementation of diets with a high but non-toxic dose of Zn is not an effective method of reducing the concentration of Pb in blood at Pb-B previously recognized as safe. However, the therapy consisting of zinc supplementation to support the action of chelators could be crucial for the elimination of Pb from the body.
