Abstract. Background: Hypovitaminosis D is a vitamin deficiency that has been increasing in developed countries; it was also suggested as an emerging risk factor for developing of atherosclerosis and acute myocardial infarction. The primary source of vitamin D is its cutaneous synthesis under exposure to sunlight. It has been suggested that 30 min of sun exposure twice weekly leads to sufficient vitamin D synthesis. The residents of Trieste (Italy) are well-known for their high exposure to sunlight in all seasons. We aimed to investigate the vitamin D status in subjects with acute myocardial infarction living in this area. Methods: Vitamin D status was identified in 478 subjects diagnosed with acute myocardial infarction. Results: The median serum 25-hydroxyvitamin D concentration was 14.5 [7.8 - 22.7] ng/mL. Vitamin D deficiency and insufficiency were present in 324 (68 %) and 107 (22 %) subjects, respectively. Vitamin D deficiency was less frequent among subjects enrolled in the period from July to the end of September (p < 0.001). In a multivariate analysis vitamin D deficiency was predicted by older age (p = 0.02), female gender (p = 0.002), higher body mass index (p = 0.05), autumn/winter sampling (p < 0.001), increased parathyroid hormone (p = 0.03) and alkaline phosphatase (p = 0.003). Conclusions: We observed very high prevalence of vitamin D deficiency among subjects with myocardial infarction in all seasons of enrollment. However, it was lower in the summer when sun exposure is higher. The exposure to sunlight may be a cost-saving therapeutic strategy for the management of vitamin D deficiency.

SummaryThe use of plasma thrombospondin (TSP) concentration was investigated as an indicator of intravascular platelet activation. Patients (n = 20) with diseases that have known vasculitis were included in the study. The range and the mean of plasma TSP concentrations of patients with vasculitis were 117 ng/ml to 6500 ng/ml and 791±1412 ng/ml (mean ± SD); the range and the mean of plasma TSP concentrations of control individuals (n = 33) were 13 ng/ml to 137 ng/ml and 59±29 ng/ml. When plasma TSP concentrations were correlated with plasma concentrations of another platelet activation marker, β-thromboglobulin (P-TG), it was found that the TSP concentration inei eased exponentially as the plasma β-TG level rose. A positive correlation between plasma levels of plasma TSP and serum fibrin degradation products was also observed. The results suggest that platelets are the primary source of plasma TSP in patients with various vasculitis and that plasma TSP can be a better indicator than β-TG to assess intravascular platelet activation due to its longer circulation half life.

SummarySeveral “in vitro” and “in vivo” studies indicate that heparin administration may affect platelet function. In this study we investigated the effects of prophylactic heparin on thromboxane (Tx)A2 biosynthesis “in vivo”, as assessed by the urinary excretion of major enzymatic metabolites 11-dehydro-TxB2 and 2,3-dinor-TxB2. Twenty-four patients who were candidates for cholecystectomy because of uncomplicated lithiasis were randomly assigned to receive placebo, unfractionated heparin, low molecular weight heparin or unfractionaed heparin plus 100 mg aspirin. Measurements of daily excretion of Tx metabolites were performed before and during the treatment. In the groups assigned to placebo and to low molecular weight heparin there was no statistically significant modification of Tx metabolite excretion while patients receiving unfractionated heparin had a significant increase of both metabolites (11-dehydro-TxB2: 3844 ± 1388 vs 2092 ±777, p <0.05; 2,3-dinor-TxB2: 2737 ± 808 vs 1535 ± 771 pg/mg creatinine, p <0.05). In patients randomized to receive low-dose aspirin plus unfractionated heparin the excretion of the two metabolites was largely suppressed thus suggesting that platelets are the primary source of enhanced thromboxane biosynthesis associated with heparin administration. These data indicate that unfractionated heparin causes platelet activation “in vivo” and suggest that the use of low molecular weight heparin may avoid this complication.

This paper discusses the content of Q.S. al-Baqarah ([2]: 67-73). The data used in the preparation of this paper is the data that is primary and secondary. The primary source is data obtained from the core source. In conducting a study of a verse, it is clear that the primary data source is derived from the Qur'an,precisely on Q.S. al-Baqarah ([2]: 67-73). Secondary data is dataobtained from other sources that are still related to the problemand provide interpretation of the primary source. The method usedin analyzing this paper is the tahlili method. This method describesthe meaning contained by the Qur'an, verse by verse, and letterafter letter according to the order in the Mushaf. The descriptionincludes the various aspects which the interpreted verses contain,such as the meaning of the vocabulary, the connotation of thesentence, the background of the verse down, its relation to otherverses, both before and after. And do not miss the opinion that hasbeen given regarding the interpretation of these verses, whetherdelivered by the Prophet, companions, the tabi'in, as well as othercommentators. This study shows that in Q.S. (2): 67-73) there arevalues of moral education which include: 1) morals in asking, (2)morals to parents, (3) patience of educators, (4) educator honesty,and (5) obedience of learners.

English for Academic Purposes course focusing on the academic language needs of students is a subfield of English for Specific Purposes (ESP). It is a type of specialized course to integrate specific subject matter, language content, and material based on learners’ needs. The study aims to evaluate the British Council’s English for Academic Purposes (EAP) coursebook in terms of content, sequencing, learners’ autonomy, motivation, feedback and focus on language skills. Furthermore, the study tries to provide a general perception of the usefulness and effectiveness of the coursebook for undergraduate students. The EAP Students’ Manual coursebook is used as a primary source for the data collection. The researcher has chosen Nation & Macalister (2010) model of language teaching principles to analyze and discuss the data. The study found the coursebook a useful, effective and an appropriate source of English language learning in terms of the investigated aspects of the book. The findings report that the coursebook provides practice and practical usage in all domains of the academically required English language skills. It helps the students to build language competency and to be more independent learners. In addition, it provides an opportunity to the learners to think in the target language, use the language more practically and learn it in a natural type of environment. The study concludes and suggests that the content needs to be supplemented with English language audios and videos presenting the students relevant documentaries and helping material in order to make the coursebook and the learning process more useful, effective, interesting and motivating. Furthermore, the study recommends that while choosing /designing a coursebook for a certain course, it needs to be evaluated following the various criteria and language-teaching-principles suggested by different language researchers.

The Impact

Arnold Schoenberg and Thomas Mann, two towering figures of twentieth-century music and literature, both found refuge in the German-exile community in Los Angeles during the Nazi era. This complete edition of their correspondence provides a glimpse inside their private and public lives and culminates in the famous dispute over Mann's novel Doctor Faustus. In the thick of the controversy was Theodor Adorno, then a budding philosopher, whose contribution to the Faustus affair would make him an enemy of both families. Gathered here for the first time in English, the letters are complemented by diary entries, related articles, and other primary source materials, as well as an introduction that contextualizes the impact that these two great artists had on twentieth-century thought and culture.
