Glucose,cholesterol,total proteins and insulin-like growth factor typeI values in the follicular fluid of female river buffaloes (Bubalus bubalis)

Twenty six Murrah female river buffaloes, between 45 and 70 d post-partum, empty, multiparae, with an average live weight of 675 ± 56 kg, and average body condition of 3.5 points, in a 1 to 5 scale, were used to determine the concentrations of glucose, cholesterol, total protein and insulin-like growth factor type I(IGF-I) in the follicular fluid. The fluid was collected from dominant follicles, with diameters between 8 and 12 mm, by in vivo follicular aspiration. The oestrous cycle stage was not taken into account. The wave of follicular development was synchronized six days prior to the collection. Biochemical analyses of glucose and cholesterol were performed by the enzymatic colorimetric method with the utilization of commercial kits of Glicose (GOD-PAP) and Cholesterol (CHOD-PAP) (Kovalent), respectively. For the determination of total protein, the commercial kit total Protein (Kovalent), method Biuret, was employed. Readings were carried out through absorption spectrophotometry with visible light. Through the radioimmunoanalysis (RIA) technique the concentration of IGF-I was obtained using commercial kits of IRMA IGF-I (IMMUNOTECH). Descriptive statistics was used, by applying the PROC MEANS procedure of the SAS (2009) statistical package. Glucose concentrations (4.0 ± 0.75 mmol/L) and IGF-I (340 ± 129.83 ng/mL) showed higher values in female river buffaloes and dairy cows regarding those reported in other studies. However, cholesterol levels (0.51 ± 0.12 mmol/L) and total proteins (58.4 ± 4.43 g/L) were lower. Results indicate that there is a relationship between the concentration of biochemical indicators, the nutritional aspects, the diameter of the aspired follicles and the productive period.

Petrogenesis of syntectonic granites emplaced at the transition from thrusting to transcurrent tectonics in post-collisional setting: Whole-rock and Sr-Nd-Pb isotope geochemistry in the Neoproterozoic Quatro Ilhas and Mariscal Granites, Southern Brazil

The Neoproterozoic post-collisional period in southern Brazil (650-580 Ma) is characterized by substantial volumes of magma emplaced along the active shear zones that compose the Southern Brazilian Shear Belt. The early-phase syntectonic magmatism (630-610 Ma) is represented by the porphyritic, high-K, metaluminous to peraluminous Quatro Ilhas Granitoids and the younger heterogranular, slightly peraluminous Mariscal Granite. Quatro II has Granitoids include three main petrographic varieties (muscovite-biotite granodiorite mbg; biotite monzogranite - bmz: and leucogranite - lcg) that, although sharing some significant geochemical characteristics, are not strictly comagmatic, as shown by chemical and Sr-Nd-Pb isotope data. The most primitive muscovite-biotite granodiorite was produced by contamination of more mafic melts (possibly with some mantle component) with peraluminous crustal melts; the biotite monzogranite, although more felsic, has higher Ca, MgO,TiO2 and Ba, and lower K2O, FeOt, Sr and Rb contents, possibly reflecting some mixing with coeval mafic magmas of tholeiitic affinity; the leucogranite may be derived from pure crustal melts. The Mariscal Granite is formed by two main granite types which occur intimately associated in the same pluton, one with higher K (5-6.5 wt.% K2O) high Rb and lower CaO, Na2O, Ba and Zr as compared to the other (3-5 wt.% of K2O). The two Mariscal Granite varieties have compositional correspondence with fine-grained granites (fgg) that occur as tabular bodies which intruded the Quatro Ilhas Granoitoids before they were fully crystallized, and are inferred to correspond to the Mariscal Granite feeders, an interpretation that is reinforced by similar U-Pb zircon crystallization ages. The initial evolution of the post-collisional magmatism, marked by the emplacement of the Quatro Ilhas Granitoids varieties, activated sources that produced mantle and crustal magmas whose emplacement was controlled both by flat-lying and transcurrent structures. The transition from thrust to transcurrent-related tectonics coincides with the increase in the proportion of crustal-derived melts. The transcurrent tectonics seems to have played an essential role in the generation of mantle-derived magmas and may have facilitated their interaction with crustal melts which seem to be to a large extent the products of reworking of orthogneiss protoliths.

Drammatizzazioni devozionali del Venerdì santo a Milano in età post-tridentina: la processione con Misteri dei Barnabiti

La tesi si occupa della «processione con Misteri» organizzata da Carlo Bascapè, preposito generale dei Barnabiti, a Milano, la notte del venerdì santo, a partire dal 1587. Di questo importante rito processionale sono giunte fino a noi diverse testimonianze documentarie, conservate presso l’Archivio Storico dei Barnabiti a Milano, che sono state il cuore di questa ricerca. La processione è una grande meditazione pubblica dove la musica svolge un ruolo molto importante. Il percorso che ho seguito è stato teso a rendere ragione delle motivazioni drammatiche e devozionali della processione, per poi approdare al significativo ruolo che la componente musicale svolgeva nel rito stesso. Nel primo capitolo ho rievocato la figura di Carlo Bascapè (1550-1615), inserendo la sua figura all’interno delle esperienze storiche nelle quali si è formato (la Milano di san Carlo Borromeo e l’Ordine dei Chierici regolari di San Paolo). Nel secondo capitolo ho scandagliato le radici devozionali alla base della processione (i concetti di devozione e orazione) e messo a fuoco il ruolo della musica nell’esperienza religiosa dei Barnabiti e, in particolar modo, di Carlo Bascapè. Il terzo capitolo si concentra sulle principali modalità di rappresentazione e meditazione della passione di Cristo. Nel quarto capitolo ho ricostruito, attraverso una lettura dei documenti, e con approfondimenti tratti dalla letteratura devozionale tardocinquecentesca sulla passione, i vari aspetti della processione e i suoi protagonisti (religiosi, nobili della città di Milano, musicisti), e, infine, ho messo in luce gli aspetti devozionali e drammaturgici. Nel quinto capitolo ho analizzato le musiche superstiti, pervenendo alla conclusione che ogni aspetto musicale era concepito tenendo ben presenti i due aspetti su cui era imperniata la processione: la rappresentazione della passione e l’immedesimazione dei fedeli. L’ultima parte della tesi consiste, infine, nella trascrizione dei documenti archivistici, nella loro parte testuale e musicale.

Il contributo della psicopatologia ansiosa materna prenatale sul temperamento infantile e la relazione precoce madre-bambino

La sintomatologia ansiosa materna nel periodo prenatale risulta influire negativamente non sullo stato materno ma anche sul successivo sviluppo infantile, Tuttavia, sono limitati gli studi che hanno considerato lo specifico contributo dei disturbi d’ansia nel periodo prenatale. L’obiettivo generale dello studio è quello di indagare nel primo periodo post partum la relazione tra psicopatologia ansiosa materna e: temperamento e sviluppo neonatale, qualità del caregiving materno e dei pattern interattivi madre-bambino. 138 donne sono state intervistate utilizzando SCID-I (First et al., 1997) durante il terzo trimestre di gravidanza. 31 donne (22,5%) presentano disturbo d’ansia nel periodo prenatale. A 1 mese post partum il comportamento del neonato è stato valutato mediante NBAS (Brazelton, Nugent, 1995), mentre le madri hanno compilato MBAS (Brazelton, Nugent, 1995). A 3 mesi postpartum, una sequenza interattiva madre-bambino è stata videoregistrata e codificata utilizzando GRS (Murray et al., 1996). La procedura dello Stranger Episode (Murray et al., 2007) è stata utilizzata per osservare i pattern interattivi materni e infantili nell’interazione con una persona estranea. I neonati di madri con disturbo d’ansia manifestano alle NBAS minori capacità a livello di organizzazione di stati comportamentali, minori capacità attentive e di autoregolazione. Le madri ansiose si percepiscono significativamente meno sicure nell’occuparsi di loro, valutando i propri figli maggiormente instabili e irregolari. Nell’interazione face to face, esse mostrano comportamenti significativamente meno sensibilI, risultando meno coinvolte attivamente con il proprio bambino. Durante lo Stranger Episode, le madri con fobia sociale presentano maggiori livelli di ansia e incoraggiando in modo significativamente inferiore l’interazione del bambino con l’estraneo. I risultati sottolineano l’importanza di valutare in epoca prenatale la psicopatologia ansiosa materna. Le evidenze confermano la rilevanza che può assumere un modello multifattoriale di rischio in cui i disturbi d’ansia prenatali e la qualità del caregiving materno possono agire in modo sinergico nell’influire sugli esiti infantili.

Farmacocinetica della buprenorfina, e del suo metabolita norbuprenorfina, somministrata come infusione costante nel periodo post-operatorio in cagne sane sottoposte ad ovariectomia

Il dolore non è solo una conseguenza della malattia ma un fattore patogeno che è di per se stesso in grado di perpetuare il danno all’organismo. Il suo trattamento non è quindi solo un atto di umanità ma un contributo ad arrestare la malattia e restituire la salute al paziente. Tra i farmaci più popolari per la terapia del dolore negli animali da affezione si trova la buprenorfina. Questa molecola viene impiegata con successo da anni nel cane e nel gatto per motivi riconducibili, oltre che alla sua efficacia (la sua potenza è diverse volte quella della morfina), alla lunga durata d’azione e alla scarsità degli effetti collaterali. Nonostante l’ampia diffusione e longevità del suo utilizzo, però, sappiamo poco della farmacocinetica di questa molecola negli animali da affezione; i dosaggi clinicamente impiegati sono di fatto estrapolati dagli studi nell’uomo oppure basati su semplici osservazioni degli effetti; i pochi dati farmacocinetici ottenuti nel cane fanno riferimento a singoli boli di dosi che non sempre corrispondono a quelle clinicamente impiegate. Nonostante la buprenorfina trovi il suo principale impiego nelle somministrazioni protratte a lungo (durante il periodo post-operatorio o la degenza ospedaliera) non è mai stato indagato il profilo farmacocinetico della molecola somministrata a boli ripetuti o come infusione continua. Il nostro studio si pone come obiettivo di indagare la farmacocinetica della buprenorfina somministrata come bolo di carico seguito da un’infusione costante a dosaggi considerati clinici in cani sani nel periodo post operatorio. Lo scopo ultimo è quello di sviluppare un protocollo per la somministrazione di questa molecola in modo prolungato in pazienti degenti ed addolorati per poi, in futuro, confrontare la somministrazione come infusione continua con i tradizionali boli ripetuti. Per lo studio sono state utilizzate giovani cagne adulte di taglia media o grande sottoposte ad intervento di ovariectomia.

Gestione pre, intra e post-operatoria del cane sottoposto ad ipofisectomia transfenoidale

L’approccio chirurgico agli adenomi ipofisari ACTH secernenti è la terapia d’elezione nell’uomo. L’ipofisectomia transfenoidale è invece una tecnica poco diffusa in ambito veterinario. La terapia più diffusa nel cane con ipercortisolismo ipofisi dipendente (PDH) è di tipo medico e prevede la somministrazione di farmaci inibitori della sintesi del cortisolo. Gli adenomi ipofisari possono aumentare di volume e determinare una conseguente sintomatologia neurologica; in questi casi le uniche opzioni terapeutiche sono rappresentate dall’asportazione chirurgica della neoplasia e dalla radioterapia. Nella presente tesi vengono descritti 8 interventi di ipofisectomia transfenoidale effettuati su 7 cani con macroadenoma ipofisario presso il Dipartimento di Scienze Mediche Veterinarie dell’Università di Bologna. La difficoltà maggiore per il chirurgo è rappresentata dalla localizzazione della fossa ipofisaria rispetto ai punti di repere visibile in tomografia computerizzata o in risonanza magnetica nucleare, oltre ai problemi di sanguinamento durante la rimozione della neoplasia. Nel periodo post-operatorio maggiori complicazioni si riscontrano in soggetti con adenomi ipofisari di maggiori dimensioni. Al contrario, in presenza di adenomi di dimensioni più contenute, la ripresa post-operatoria risulta più rapida e il tasso di successo maggiore. Al fine di poter eseguire nel cane l’exeresi mirata della sola neoplasia ipofisaria, al pari di quanto avviene nell’uomo, è stato condotto uno studio sulla tomografia computerizzata (TC) in 86 cani con PDH. Il protocollo TC non ha tuttavia permesso di individuare con precisione la posizione della neoplasia per guidare il chirurgo nella sua rimozione. In due casi riportati nel presente lavoro si è verificata una recidiva della neoplasia ipofisaria. In un soggetto si è optato per il reintervento, mentre nell’altro caso per la radioterapia. Entrambe le opzioni hanno garantito una buona qualità di vita per più di un anno dall’intervento terapeutico. Questi casi clinici dimostrano come il reintervento e la radioterapia possano essere considerate valide opzioni in caso di recidiva.

Coordinated gene expression in adipose tissue and liver differs between cows with high or low NEFA concentrations in early lactation

Dairy cows with high and low plasma non-esterified fatty acid (NEFA) concentrations in early lactation were compared for plasma parameters and mRNA expression of genes in liver and subcutaneous adipose tissue. The study involved 16 multiparous dairy cows with a plasma NEFA concentration of >500 mumol/l [n = 8, high NEFA (HNEFA)] and <140 mumol/l [n = 8, low NEFA (LNEFA)] in the first week post-partum (pp). Blood samples, adipose and liver tissues were collected on day 1 (+1d) and at week 3 pp (+3wk). Blood plasma was assayed for concentrations of metabolites and hormones. Subcutaneous adipose and liver tissues were analysed for mRNA abundance by real-time qRT-PCR encoding parameters related to lipid metabolism. Results showed that mean daily milk yield and milk fat quantity were higher in HNEFA than in LNEFA cows (p < 0.01), and the NEB was more negative in HNEFA than in LNEFA in +3wk too (p < 0.05). HNEFA cows had slightly lower (p < 0.1) insulin concentrations than LNEFA cows across the study period, and the body condition score decreased more from +1d to +3wk in HNEFA than in LNEFA (p = 0.09). The mRNA abundance of genes in the liver related to fatty acid oxidation (carnitine palmitoyltransferase 2 and very long chain acyl-coenzyme A dehydrogenase) and ketogenesis (3-hydroxy-3-methylglutaryl-coenzyme A synthase 2) were lower in HNEFA than in LNEFA cows. No differences between the two groups were observed for mRNA expression of genes in adipose tissue. The number of calculated significant correlation coefficients (moderately strong) between parameters in the liver and in adipose tissue was nearly similar on +1d, and higher for HNEFA compared with LNEFA cows in +3wk. In conclusion, dairy cows with high compared with low plasma NEFA concentrations in early lactation show differentially synchronized mRNA expression of genes in adipose tissue and liver in +3wk that suggests a different orchestrated homeorhetic regulation of lipid metabolism.

Metabolic status and oestrous cycle in dairy cows

A study with 40 multiparous high yielding dairy cows was conducted to investigate the influence of an induced negative energy balance (NEB) on reproductive performance. Energy restriction of 49% was performed for 3 weeks beginning on oestrous cycle day 12 of first oestrous cycle after day 85 post partum (pp). From day 20 to day 150 pp animals were monitored for ovary activity three times weekly using rectal palpation and transrectal ultrasound scanning and were inseminated around day 150 pp. Additionally, milk progesterone and milk hydrocortisone were analyzed twice a week. Body condition score and body weight as well as blood glucose, plasma nonesterified fatty acids and plasma β-hydroxybutyrate were recorded weekly. According to oestrous cycle activity before (Period 1 = natural energy deficiency), during (Period 2) and after (Period 3) induced energy restriction animals were assigned to the following groups: Delayed first ovulation until day 45 pp, normal oestrous cycle, prolonged oestrous cycle and shortened oestrous cycle. Sporadic significances, but no clear effect of the metabolic state on reproductive performance could be found during Periods 1 and 2. Service success and conception rate were also not influenced. Our results demonstrate a remarkable adaptation of reproductive activity to metabolic challenges. Animals were able to compensate natural NEB in Period 1 as well as induced NEB (Period 2) for preventing metabolic disorders and maintaining reproductive activity. Therefore dietary energy availability had no effect on reproductive performance at more than 85 days in milk in the present study. To understand reproductive failures in dairy cows focus should be laid on genetic disposition of high yielding individuals that cope successful with metabolic challenges.

Repression, Anpassung, Neuorientierung: Islamische Bildung im sowjetischen und post- sowjetischen Raum

How did Islam survive in the Soviet Union, and how did it develop since 1991? In four case studies and four longitudinal surveys, senior specialists from the area and two German junior scholars discuss the transformations of Islam in Tatarstan, Azerbaijan, Daghestan, Uzbekistan and Tajikistan. Several chapters analyze the Bolsheviks’ attack on Islam since the 1920s. Altay Göyüşov and Il’nur Minnullin demonstrate how the Soviets first attempted to draw some groups of Muslim scholars and intellectuals to their side, in Azerbaijan and Tatarstan, respectively. In the early 1930s collectivization and outright state terror made a complete end to the Islamic infrastructure, including mosques and pious foundations, Muslim village courts (as shown by Vladimir Bobrovnikov for Dagestan), Islamic educational institutions (as documented by Aširbek Muminov for Uzbekistan), as well as the Muslim press (analyzed by Dilyara Usmanova for Tatarstan); also Sufi brotherhoods became a main target of violent repression (Šamil‘ Šixaliev, for Dagestan). Repression was followed by the establishment of a modus vivendi between state and religion in the post-war period (Muminov, Bobrovnikov, Šixaliev), and by the instrumentalization of religion for patriotic purposes in the post-Soviet Caucasus and Central Asia (Christine Hunner-Kreisel, Manja Stephan, both based on fieldwork). By the early 2000s Islam was almost everywhere back under full state control; the leading role of the state for defining „good“ and „bad“ Islam is largely taken for granted. While similar forms of state pressure in all regions thus allow us to draw an overall picture of how Islamic traditions were repressed and reanimated, the „archival revolution“ of the early 1990s provides fascinating insights into the specific developments in the individual regions, and into the adaptation strategies of the Muslim scholars and intellectuals on the spot. Still, the Soviet heritage is still very palpable; also the attempts to leapfrog the Soviet period and to link up again with the individual local Islamic traditions from before 1917, and even the negation of the Soviet experience in the form of embracing Islamic trends from abroad, are often still couched in largely Soviet mental frameworks.

Continuous milking of dairy cows disrupts timing of peak IgG concentration appearance in mammary secretions

The length of the dry period in commercial dairy production is under close scrutiny. While the main concern is the composition and volume of milk produced, the evaluation of colostrum quality under these new paradigms has suggested a decline in IgG concentrations, while some reports indicate no change. Colostrum quality has been defined as an adequate concentration (>50 mg/ml) of immunoglobulin in the secretions to provide the newborn with maximal disease resistance. We investigated the appearance of IgG in mammary pre- and post partum secretions in cows without a dry period (continuously milked, Dry0) and compared the secretions with cows that experienced a dry period of 60 d (Dry60). Blood was collected during the experimental period and plasma analysed for progesterone (P4) and prolactin (Prl). Approximately -6 d relative to parturition, the Dry0 animals exhibited increased concentration of IgG in their secretions to an average of ∼35 mg/ml that remained rather constant through subsequent pregnancy and following parturition. Dry0 cows were producing an average IgG concentration in parturition colostrum of 44·2±17·6 mg/ml that was not different than that of controls (66·86±16·8 mg/ml). However, Dry0 cows exhibited high variation, different peak times (day) of IgG concentration including times that occurred both pre and post parturition. IgG mass of the Dry0 cows remained rather constant pre- and post partum and did not show the same declining mass following parturition that was shown for the Dry60 cows. The change in plasma P4 and Prl were shown to have no timing effect on colostrum IgG concentration.

Treatment of Retained Fetal Membranes: Comparison of the Postpartum Period after Routine Treatment or Routine Treatment Including an Additional Phytotherapeutic Substance in Dairy Cattle in Switzerland

Background: The therapy of retained fetal membranes (RFM) is a controversial subject. In Switzerland, intrauterine antibiotics are routinely administered although their effect on fertility parameters is questionable. The objective of this study was to compare the post-partal period after a routine treatment of RFM in 2 groups: one group received a placebo additionally (A), whereas the other group received a phytotherapeutic substance (lime bark) (B) additionally. The routine treatment of RFM included an attempt to manually remove the fetal membranes (for a maximum of 5 min), intramuscular administration of oxytetracycline and intrauterine treatment with tetracycline. In case of an elevated rectal temperature (>39.0°C), an additional non-steroidal inflam-matory drug was allowed. Methods: Cows undergoing caesarean section, suffering from prolapse of the uterus, deep cervical or vaginal injuries, hypocalcaemia, and illnesses during the last 14 days before calving were excluded. Cows had to be more than 265 days pregnant. Only cows that were artificially inseminated after RFM were included. Group stratification was done according to the last number on the ear tag (even/uneven) with (n = 50) cows in group A and (n = 55) cows in group B. Results: The number of treatments after the initial treatment of RFM was not significantly different between groups. The median interval from calving to the first insemination was 77 days in group A compared to 82 days in group B (p = 0.72). The number of AI’s until conception was not significantly different between groups. The median number of days open was 89 days in group A compared to 96 days in group B (p = 0.57). The culling rate was not significantly different between groups. Conclusion: There was neither a difference between the groups concerning therapies within the first 50 days after RFM nor concerning the subsequent fertility variables.

Prenatal care programs in a clinic based center in El Paso, Texas: Evaluating outcomes among Hispanic women

Early prenatal care has been found to improve pregnancy and birth outcomes by reducing the risk of low birth weight and preterm births. Statistics point to lower utilization rates of prenatal care in El Paso, Texas and increasing rates of low birth weight. This study was a secondary data analysis, which explored the perceived benefits and barriers known to influence the utilization of prenatal care, and the birth outcomes among participating subjects attending three different prenatal care programs offered at the Centro San Vincent Clinic during the period of December 2006 to February 2008. A survey was used to collect data on demographics and assess perceived benefits and barriers regarding early prenatal care and self-efficacy of the participants. Post-partum birth records were used to gather data about the participant's newborns to include birth weight, gestational age, and the type of delivery (i.e. vaginal versus Cesarean birth). Chi square analysis was conducted to test for significant differences and associations. The sample of women in the study had high risk factors for inadequate utilization of prenatal care. In spite of high demographic risk factors, these women had higher perceived benefits, lower perceived barriers and high self-efficacy associated with prenatal care utilization. The perceived benefits and barriers to prenatal care were associated with place of birth and language preferred, with women from Mexico and who preferred Spanish having higher perceived benefits and lower barriers. There was no significant difference in birth outcomes among the women in different prenatal care programs. The findings of this study suggest that of all participants in the study, those born in Mexico demonstrated higher rates of perceived benefits of early prenatal care. The analysis also suggested that healthy birth outcomes were evenly distributed among women participating in one of the three prenatal care programs. ^

Blunted prolactin response to D-fenfluramine in post-stroke major depression

Background: This study investigated whether patients suffering from post-stroke depressive disorder had a similar disturbance in central serotonergic function to that described in non-brain injured depressed patients. Methods: Twenty-three depressed patients (nine major, 14 minor) and 38 non-depressed patients were examined 4-8 weeks post-stroke with a structured interview, rating scales and MRI brain scans. Patients were administered 30 mg D-fenfluramine orally and plasma prolactin and D-fenfluramine concentrations were measured for 6 h post-dose. Results: The prolactin response was significantly blunted in major depression compared to minor depression and non-depressed patients as measured by both delta prolactin and area under the prolactin versus time curve. There was no significant relationship between prolactin response and lesion lateralization or any of the measured clinical characteristics. Limitations: The major limitation of the study is the relatively small number in each depressive group. Conclusions: Patients suffering from major depression in the post-stroke period have a blunted prolactin response to D-fenfluramine. This indicates a serotonergic abnormality consistent with that found in major depression where neurological disease is not present. (C) 2003 Elsevier B.V. All rights reserved.
