Opis:
Butenolides and their analogues represent a wide range of natural compounds of a medical and biological importance. In the last decades, a great number of compounds of various structures, in general from Alkylidene butenolide, were isolated and showed biological activities. In this work we have studied the reactivity of some alkylidene butenolide and their antibacterial activity. the study is of a scientific interest in terms of the synthesis of new compounds (Butenolide 01: 5-hydroxy-5-(1-methoxypropan-2-yl)-4-methylfuran-2(5H)-one, Butenolide 02: 5-(1-methoxypropan-2-yl)-4-methylfuran-2(5H)-one) that have not been studied before by other researchers; and of an economic importance because of its synthesis process which is easy and inexpensive. Moreover, butenolide showed a positive antimicrobial activity (antibiotic) against pathogenic bacteria (mainly Enterobacter hafniae).

fructose-1,6-bisphosphatase
Opis:
Phosphorylated fructose-1,6-bisphosphatase (FBPase) was isolated from rabbit muscle in an SDS/PAGE homogeneous form. Its dephosphorylation with alkaline phosphatase revealed 2.8 moles of inorganic phosphate per mole of FBPase. The phosphorylated FBPase (P-FBPase) differs from the dephosphorylated enzyme in terms of its kinetic properties like Km and kcat, which are two times higher for the phosphorylated FBPase, and in the affinity for aldolase, which is three times lower for the dephosphorylated enzyme. ephosphorylated FBPase can be a substrate for protein kinase A and the amount of phosphate incorporated per FBPase monomer can reach 2-3 molecules. Since interaction of muscle aldolase with muscle FBPase results in desensitisation of the latter toward AMP inhibition (Rakus & Dzugaj, 2000, Biochem. Biophys. Res. Commun. 275, 611-616), phosphorylation may be considered as a way of muscle FBPase activity regulation.

1Cor 6
Opis:
II testo di 1 Cor 6,17 benchè abbonda di contenuto teologico assai interessante, oltre che ci offra buon esempio di coraggiosa maniera con cui Paolo seppe dall’antitesi inaspettata ricavar utile per far meglio apparire il suo pensiero, nondimeno questo testo non è stato abbastanza spiegato finora. II versicolo 17 fa parte della replica di Paolo sopra dignità e santità del corpo umano, istituita essa a cagione di sbagliata interpretazione della libertà cristiana da parte dei Corinti, chi la applicarono alla vita sessuale. Nei versicoli 16 e 17 insieme, risulta un’antitesi di tipo: σαρξ— πνευμα ο σωμα— πνευμα. Gli esegeti si occupavano già di trovare la ragione per cui Paolo nel v. 16 potè servirsi della citazione di Gen. 2,24, relativamente riguardante il caso del matrimonio legittimo, applicandola all’unione peccaminosa di cristiano con meretrice; cercavano inoltre di determinare il senso proprio delle parole usate nell’antitesi (σαρξ ο σωμα in riguardo a πνευμα).  Questa occasione approfittando è stata sottolineata la vicinanza di signifieazione tra 1’antitesi σαρξ (σωμα) — πνευμα e tra un’altra antitesi, pure essa paolina, cioè σωμα ψυχικον —  σωμα πνευματικον. Aiutandosi dell’ultima aspiravano pervenir alla più profonda spiegazione della prima antitesi (σαρξ — πνευμα nei vv. 16 e 17). Comiciando anche con 1’analisi del significato di verbo κολλασθαι si esaminava presso gli esegeti diverse possibilità per cui il fedele cristiano potesse unirsi con Cristo; così si sperava di venire a stabilire il contenuto dell’espressione „uno spirito”. Il più incompensabile mancamento delle soluzioni finora messe alla luce, segue dalia troppo poca avvertenza all’argomentazione nella pericope di 1 Cor. 6,12—20 in tutto, di cui fa parte il v. 17, che ci interessa specialmente. A questo mancamento appunto si vorrebbe che fosse adempito, perciò nel l’articolo nostro si dà più d’emfasi all’inquadrare bene il v. 17 nel l’argomentazione insieme, di cui ne si trova. Interpretando quel testo non si può mai oltrepassare lo schema di composizione della pericope, siccome l’argomento dell’Apostolo fu stato composto, già cominciare dal v. 13a, simmetricamente, usando Lui degli antitesi. In tale genere di composizione il versicolo 17 fa compito d’indicare meglio quanta diversità esiste tra le consequenze del peccato immondo e tra effetti della unione con Cristo. In ciò che riguardala genesi dell’antitesi σαρξ (σωμα) — πνευμα nei vv. 16 e 17, c’è da accettare con grande probabiltà, che Paolo, secondo il suo costume, già col v. 17 cominciò di preparare i suoi lettori al pensiero sulló Spirito Santo, di cui poco più avanti gli viene a dire. A questo fine volle in antecedenza introdurre il termine πνευμα. Così psycologicamente sviluppa Paolo il suo argomento passando dalle cose più note (le quali di solito introduce con ουκ οιδατε οτι) alle cose meno conosciute, di cui gli occorre dare ancora una spiegazione. Alla stessa conclusione, cioè che al σωμα, con cui vengono unite due persone umane nel v. 16, corrisponde in v. 17 lo spirito di Cristo, che vuol dire le Spirito santo, il fattore del Corpo mistico, ci conduce dalia sua parte anche 1’analisi dell’antitesi nei vv . 16 e 17. Per il contesto remoto, che ci può giovare nel spiegare il carattere dell’unione con Cristo, secondo il v. 17 bisognerebbe scegliere tali testi, in cui l’espressione εν πνευμα significha l’unione assorbente tutta la persona umana, oltre che dovrebbe essere legato alla speranza nella risurrezione corporale, e di più un tale, che potrebbe darsi presentare sotto la metafora di corpo e dei membri. Finalmente dovrebbero venir fuori i testi nel suo insieme riferibili a Cristo. Alle sopra elencate condizioni corrispondono proprio i seguenti testi della stessa lettera paolina: 1 Cor. 12,12.13.27 e 15,42.45, i quali conseguentemente vengono assunti all’approfondire la spiegazione di 1 Cor. 6,17. La concludione dell’analisi di 1 Cor. 6,17 è come segue: Questi s’unisce con Cristo, chi possiede lo spirito divino ossia lo spirito di Cristo, ciò vuol dire quello spirito ch’è proprio di Cristo stesso. L’espressione nel 1 Cor. 6,17: „chi aderisce al Signore forma un solo spirito con Lui” significa che un tale gode dello stesso Spirito santo col Signore per cui gli è permesso d’avere una ben fondata speranza di risurrezione, perchè il Cristo risorto è lo „spirito vivificatore”. Durante la vita terrena il cristiano già è tempio di Spirito santo. L’unione con Cristo, di cui si parla nel v. 17, è niente altro principalmente che 1’effetto del battesimo (allora 1’inserimento al Corpo mistico di Cristo). Non occorre che sia necessariamente 1’unione mistica, strettamente detta, ossia che supponga la coscienza di partecipazione intima nella vita in Dio.

Opis:
Il primo capitolo del Libro del Siracide e dedicato alla Sapienza. Dopo la presentazione della Sapienza, il Saggio invita il suo discepolo/lettore ad acquistarla e a praticarla nella vita. Ben Sira, pero, non e idealista, percio mostra agli adepti della sua scuola le tentazioni, le difficołta e le prove che li aspettano sui sentieri della Sapienza. A questo tema viene dedicato il brano di Sir 2,1-6 che abbiamo intitolato "La fedelta durante la prova".Nella prima parte del suo poema (Sir 2,1-3), il Siracide da al suo discepolo/lettore che vuole avvicinarsi al Signore quattro consigli che riguardano la sua vita spirituale (Sir 2, 1b-2) e poi al tri due che si riferiscono al suo rapporto con Dio (2,3a). Il discepolo potra superare ogni prova soltanto se sara legato al Signore e sara costante. Per incoraggiare il suo discepolo, Ben Sira, in 2,3b, gli presenta il premio per la sua fedelta, cioe la sua crescita nella Sapienza alla fine dei suoi giomi.In Sir 2,4 inizia la seconda parte de l poema, che ha una struttura concentrica, sulla fedelta durante la prova. Ben Sira in modo particolare approfondisce il senso intero della prova. Nel versetto 5 il Maestro introduce un elemento nuovo nel suo insegnamento sulla fedelta durante la prova: una motivazione religiosa delia prova stessa. La metafora dell'oro che viene purificato nel fuoco serve al Siracide a mostrare che come nel fuoco si purifica il metallo, cosi Dio nel crogiuolo delia prova, che viene chiamata umiliazione, monda gli uomini che ama. Il discepolo puo crescere e maturare soltanto superando le prove. Cosi la prova diventa una possibilita di crescita nelia Sapienza.

Opis:
Although both uveal (UM) and cutaneous (CM) melanoma cells derive from the transformed melanocytes, their biology varies significantly in several aspects. Malignant transformation is frequently associated with alternations in cell glycosylation, in particular those concerning branched complex-type N-glycans. These changes occur principally in β1,4-N-acetylglucosaminyltransferase III (GnT-III) that catalyzes the synthesis of glycans with bisected N-acetylglucosamine (GlcNAc) and β1,6-N-acetylglucosaminyltransferase V (GnT-V) that is involved in forming β1,6-branched antenna in complex-type glycans. We searched for the reasons of a different behavior of CM and UM cells in the expression of GnT-III and GnT-V and their oligosaccharide products. Our study showed that UM cells have more β1,6-branched glycans than CM cells, what results from a higher expression of MGAT5 gene encoding GnT-V. The higher β1,6-branching of glycans in UM may contribute to their higher potential to migrate on fibronectin and weaker binding to main extracellular matrix proteins, observed in our previous studies.

Opis:
Diizocyjanian heksano-1,6-diylu (HDI) jest bezbarwną cieczą o ostrym zapachu mającą wszechstronne zastosowanie przemysłowe. Używa się jej do produkcji: poliuretanów, elastomerów, gumy syntetycznej, środków antykorozyjnych, farb i lakierów. Dane na temat toksyczności tej substancji są nieliczne. Z dostępnych informacji wynika, że jest to substancja, która dobrze wchłania się w drogach oddechowych i jest wydalana głównie z moczem. Wywiera działanie drażniące na górne drogi oddechowe i na oczy oraz powoduje nadreaktywność oskrzeli i uczulenia skóry. Diisocyjanian heksano-1,6-diylu nie indukuje mutacji w testowych szczepach Salmonella Typhimurium i nie powoduje wzrostu częstości mikrojąder w erytrocytach myszy. Diisocyjanian heksa-no-1,6-diylu nie zaburzał rozrodu i rozwoju potomstwa zwierząt, a także nie indukował nowo-tworów u szczurów w następstwie 2-letniego narażenia inhalacyjnego. Zespół Ekspertów proponuje przyjęcie następujących normatywów higienicznych diisocyjanianu heksano-1,6-diylu: najwyższe dopuszczalne stężenie (NDS) – 0,04 mg/m3 i najwyższe dopuszczalne stężenie chwilowe (NDSCh) – 0,08 mg/m3 oraz oznakowanie substancji literami „I” – substancja o działaniu drażniącym oraz „A” – substancja o działaniu uczulającym. 1,6-Hexamethylene diisocyanate (HDI)
1,6-Hexamethylene diisocyanate (HDI) is a colourless liquid with a sharp odour. It has universal industrial use; it is used to produce polyurethanes, elastomers, synthetic gum, anticorrosive preparations, paints and varnishes. There are few data on the toxicity of this substance. According to available information, it is absorbed in the respiratory tract and eliminated mainly in urine. HDI is irritating on the upper respiratory tract and on eyes; it also causes hypersensitivity of bronchi. HDI induces an allergic reaction of the skin. 1,6-Hexamethylene diisocyanate does not induce mutation in tests with Salmonella typhimurium and does not increase the frequency of micronuclei in erythrocytes of mice. HDI is not a reproductive and development toxin and is not a carcinogen for rats. The Expert Group for Chemical Agent suggests the following hygienic norms of 1,6- -hexamethylene diisocyanate : TLV – 0.04 mg/m3 and STEL – 0.08 mg/m3, “I”– an irritating sub-stance and "A” – a sensitizating substance.

Opis:
The relevant load case of open thin-walled shells is often wind loading during construction. Because of the missing stabilization effect of the roof they show a very high sensitivity to buckling which results into higher wall thicknesses. As part of the European RFCS research project BiogaSS the Institute for Metal and Lightweight Structures of the University of Duisburg-Essen carried out investigations on open thin-walled tanks made of austenitic and duplex stainless steels under wind load to study a possible economic advantage which might be gained from the consideration of the elastic postbuckling behaviour. This contribution presents not only experimental and numerical results but also first recommendations regarding the range of possible buckling reduction factors which might be incorporated in future revisions of EN 1993-1-6 and EN 1993-4-2.
Najbardziej adekwatnym przypadkiem obciążenia otwartych, cylindrycznych powłok cienkościennych jest obciążenie wiatrem podczas wznoszenia powłoki. Wobec braku stabilizującego efektu dachu, powłoki wykazują bardzo dużą wrażliwość na wyboczenie, która prowadzi do konieczności zwiększenia grubości ścian powłoki. Instytut Konstrukcji Lekkich i Metalowych Uniwersytetu Duisburg-Essen przeprowadził badania stateczności otwartych zbiorników cienkościennych wykonanych z nierdzewnych blach ze stali austenicznej i ze stali duplex poddanych działaniu obciążenia wiatrem. Celem tych badań było określenie możliwych korzyści ekonomicznych wynikających z uwzględnienia sprężystych stanów pokrytycznych. Badania te były częścią Europejskiego Projektu RFCS BiogaSS. Prezentowana praca przedstawia nie tylko wyniki badań eksperymentalnych i analiz numerycznych, lecz także pierwsze propozycje zaleceń dotyczących zakresu redukcyjnych współczynników wyboczeniowych, które w przyszłości mogą być włączone do norm EN 1993-1-6 i EN 1993-4-2.

Opis:
Nuclear reactions, which are very important from the point of view of human health, may occur during the production of the radiation sources, used in radiotherapy. The nuclear reaction data are needed in the radioisotope production procedure. The total cross section is also important in accelerator technology, in view of radiation protection and safety. In general, the significance of the cross section data for nuclear reactions in radionuclide production programs is firmly established. Gamma irradiation tracers can offer a large amount of information about the anatomy of different organs in the human body. The main purpose of this work was to compare the cross section of longer-shorter lived radionuclides. Theoretical excitation functions have been calculated with TALYS 1.6 nuclear reaction simulation code. The calculated results have been discussed and compared with the experimental data.

The warm rolling was performed at a temperature range of its recrystallization temperature, which were 400°C and 560°C, and a feed rate of 10 mm/min. Degradation behaviors of Mg-1.6Gd binary alloy was evaluated by means of potentiodynamic polarization and hydrogen evolution test in modified Kokubo’s SBF solution at temperature of 37 ± 1ºC. The lowest corrosion rate of 0.126 mm/year derived from potentiodynamic polarization test was showed by unidirectional-rolled specimen at temperature of 560°C. Hydrogen evolution test results showed the lowest hydrogen gas formed during 24 hours of immersion was found on unidirectional-rolled specimen at temperature of 560°C with a rate of 0.268 cc/cm2/hours. While cross rolled specimens showed a high corrosion and hydrogen evolution rate of 20 mm/year and 0.28 cc/cm2/hours.

Artykuł analizuje strukturę 1Hen 9,1-3 i jego funkcję w  strukturze mitu o upadłych aniołach (1Hen 6-11). Ten krótki tekst przedstawia czterech aniołów, ich postrzeganie nieszczęśliwego stanu ludzkości i przyjęcie ludzkiej skargi skierowanej do Boga. Pozytywna prezentacja czterech aniołów może zostać skontrastowana przez negatywną prezentację poległych Czuwających w 1Hen 6,2-3,7-8. Z drugiej strony, 1Hen 9,1-3 odnosi się do 1Hen 10, 1-16, gdzie ci sami czterej aniołowie otrzymują od Boga boskie zlecenie. Ponieważ stanowi decydujący zwrot w narracji mitu, 1Hen 9,1-3 dzieli go na dwie części, co implikuje symetryczny układ mitu.
The article analyses the structure of 1 En. 9:1-3 and its function within the larger structure of the myth of the fallen Watchers (1 En. 6–11). The short text introduces the four angels on the scene, their perception of the miserable state of humanity, and the reception of human complaint directed to God. The positive presentation of the four angels can be contrasted by the negative presentation of the fallen Watchers in 6,2-3.7-8. On the other hand, 1 En. 9:1-3 is related to 1 En 10:1-16 where the same four angels receive from God the divine commissioning. Since it introduces the decisive turn in the myth narrative thread, 1 En 9:1-3 divides the myth into two parts, which implies the symmetric disposition of the myth.

Opis:
This experimental study aimed to investigate some hematological and immunological changes as a result of Aeromanas hydrophila infection in Siberian sturgeon (Acipenser baerii Brandt, 1869). Their feeds were supplemented with β-1,3/1,6 glucan at different ratios, 250 mg/kg (βG 250); 500 mg/kg (βG500) and 750 mg/kg (βG750). To create an experimental infection, 4×106 cfu/ml Aeromonas hydrophila inoculum was intraperitoneally injected to fish. 0.1 ml intraperitoneal bacteria injection was given to the fish in 12 of 15 tanks, each consisting of 10 fish (the fish in the control group were not given bacteria). Considering the βG500 and βG750 group fish as positive (C+) and negative control (C−) groups in terms of hematological parameters, it was found that RBC (erythrocyte) and Hb (hemoglobin) values, as well as RBC indices (MCV, MCHC, MCH) significantly increased. The immunological parameters, including WBC (leukocyte), leukocyte cell percentages (lymphocyte, monocyte, neutrophil, eosinophil), as well as cytokines, including IL-1β, IL-6, IL-8, and TNF-α values showed similar increases in the βG500 and βG750 groups. It was found that the addition of 500 and 750 mg/kg doses of β-1,3/1,6 glucan to the feed stimulated non-specific immunity of fish against bacterial agents and/or septicemic diseases and beta glucan at this dosage range was determined to be ideal for fish health and that it may be a herbal immunostimulant that can be an alternative to many medicaments.

Opis:
The objective of this study was to determine the effect of ß-l,3/l,6-D-glucan (Biolex-Beta HP) on the phagocytic activity and oxidative metabolism of peripheral blood granulocytes and monocytes in rats intoxicated by cyclophosphamide. The experimental material comprised 40 adult Wistar rats aged 14 weeks, divided into two equal groups, a control group and an experimental group, each of 20 adult rats, including 10 males and 10 females. In the course of 3 successive days, 20 rats from the experimental group were administered cyclophosphamide intramuscularly at a dose of 50 mg/kg body weight/day. On the 8th day of the experiment, 10 control group (K) rats and 10 experimental group (C) rats were sacrificed. Arterial blood samples were collected and diluted with heparin to determine and compare the phagocytic activity (Phatogest) and oxidative metabolism (Bursttest) of peripheral blood granulocytes and monocytes by flow cytometry. Starting on the 8lh day of the experiment, the feed of the remaining 10 rats from the experimental group (C+G) and 10 rats from the control group (G) was supplemented with Biolex-Beta HP at a dose of 50 mg/kg body weight/day for 14 consecutive days. On day 22, arterial blood samples were collected from all (C+G) and (C) group rats, diluted with heparin to determine and compare the phagocytic activity and oxidative metabolism of peripheral blood granulocytes and monocytes by flow cytometry. The results showed that Biolex-Beta HP modulated the phagocytic activity and oxidative metabolism of blood neutrophils and monocytes suppressed by cyclophosphamide in rats. The immunorestoring activity of Biolex-Beta HP was observed in this study.

Opis:
We report here the protocol for the preparation of 2-amino-N'-(1-(aryl-2-oxo-2H-chromen-3-yl)ethylidene)benzohydrazides compounds in moderate to excellent yields (46–86%) within a short reaction time (10–15 min), through a clean and efficient procedure. Additionally, the method has a wide substrate scope and provides an accessible route for the large-scale direct synthesis of 2-amino-N'-(1-(aryl-2-oxo-2H-chromen-3-yl)ethylidene)benzohydrazides. The products were assayed for their in vitro biological assay antimicrobial evaluation against two Gram-negative bacteria Escherichia coli MTCC 442, Pseudomonas aeruginosa MTCC 441 and antifungal activity against Candida albicans MTCC 227, Aspergillus Niger MTCC 282, Aspergillus clavatus MTCC 1323 at different concentrations which compared with ampicillin, chloramphenicol, ciprofloxacin, norfloxacin, nystatin, and greseofulvin in as standard drugs which are presented.
