Modulation of plasma levels and percentages of incorporation of ω-3 PUFAs in egg yolk under the influence of supplementation sources rich in omega 3 to diet of laying

Hundred forty-four Shaver White laying hens were used over a 4 week experimental period to investigate the effect of 3% of soybean oil, corn oil (MIL), canola oil, flaxseed oil (LIN), salmon oil (SAL) or tuna and sardine oil (SR/AT) added to the diets, upon the fatty acid egg yolk composition, blood plasma levels and incorporation time of each fatty acid into the egg yolk. Hens were allocated into 72 cages and the experimental design was a 6 x 6 randomized factorial model. Hens fed 3% of different oils, responded with increased polyunsaturated fatty acids omega 3 (ω-3 PUFAs), except for corn oil. The addition of flaxseed, soybean or corn oil into the diet increased the PUFAs levels into the egg yolk and in the blood plasma. Adding tuna and sardine oil into the diet increased the concentration of yolk saturated fatty acids. The levels of ω-3 PUFAs were increased in the tuna and sardine oil treatment, while the flaxseed oil increased the plasma fatty acids. The deposition of 349.28 mg/yolk of a-linolenic fatty acids (ALA) was higher in the group fed LIN, while the higher equal to 157.13 mg DHA/yolk was observed in group SR/AT. In the plasma, deposition increased from 0.33% (MIL) for 6.29% ALA (LIN), while that of DHA increase of 0.47% (MIL) for 4.24% (SAL) and 4.48% (SR/AT) and of 0.98% (MIL) for 6.14% (SR/AT) and 8.44% (LIN) of ω-3 PUFAs. The percentage of EPA into the yolk and plasma was higher for the hens fed 3% tuna and sardine oil diet, as well as the levels of yolk DHA. The concentration of DHA into the plasma was higher for the salmon and tuna/sardine oil treatments. The PUFAs yolk decreased during the first eight days of experiment, while the ω-3 PUFAs increased during the same period. The concentration of ALA increased until ten days of experiment, while the percentage of EPA and DHA increased up to the eighth experimental day

Efeitos da oxigenoterapia hiperbárica e do sulfato de condroitina-A associado ao sulfato de glucosamina na reparação óssea de coelhos

Objetivo: Estudar o hemograma e avaliar radiológica e morfológicamente a reparação do calo ósseo após a lesão na diáfise femural de coelhos. Métodos: foram utilizados 48 coelhos independentes do sexo, Nova Zelândia, onde estes foram anestesiados e submetidos à ostectomia do côndilo femoral medial direito e osteossíntese, randomizados e distribuídos em 4 grupos (n = 12 em cada): Grupo Controle (I), Grupo Sulfato de Condroitina-A associado ao Sulfato de Glucosamina (II), sendo que a aplicação de Sulfato de Condroitina-A associado ao Sulfato de Glucosamina (2mL.10Kg -1 ) iniciou no pós-operatório imediato seguido de aplicações a cada 3 dias; Grupo Oxigenoterapia Hiperbárica (III): com sessões diárias (3 ATA durante 130 minutos, sendo 90 minutos de pressão absoluta) iniciadas no primeiro dia de pós-operatório; Grupo Sulfato de Condroitina-A associado ao Sulfato de Glucosamina e Oxigenoterapia Hiperbárica (IV). Os animais foram eutanasiados após 2 (n=6 de cada grupo) e 6 semanas (n=6 de cada grupo) de pós-operatório. Resultados: Diferenças significantes foram encontradas entre os grupos de 2 e 6 semanas de pós-operatório, quanto à média do comprimento do calo ósseo nos grupos: I (p = 0,001), II (p = 0,012) e IV (p = 0,001). A comparação entre os quatro grupos após 2 semanas mostrou diferença significante (p < 0,001), onde o grupo I apresentou média de comprimento caloso menor que os grupos II (p = 0,001), III (p = 0,001) e IV (p = 0,008), de maneira significante. Os demais grupos não se diferenciaram de forma significante (p > 0,05) nas demais comparações. Entretanto, após 6 semanas a comparação entre os quatro grupos mostrou diferença significante onde: o grupo I apresentou média de comprimento menor que os grupos III (p = 0,006) e IV (p < 0,001); o grupo II apresentou média de comprimento menor que os grupos III (p = 0,001) e IV (p < 0,001). Os demais grupos não se diferenciaram de forma significante (p > 0,05) nas demais comparações. Nos achados radiológicos de até duas semanas encontramos uma formação calosa rápida nos grupos que receberam oxigenoterapia hiperbárica (83% dos animais do grupo III) isoladamente ou em associação com o sulfato de condroitina-a associado ao sulfato de glucosamina (33% dos animais do grupo IV) quando comparados ao grupo controle. Já com seis semanas esta diferença diminui, mas ainda o grupo III (83%) apresenta um maior número de animais com formação calosa do que no grupo IV (67%). Sendo que os resultados radiológicos mostram a possibilidade de uma melhor ação da oxigenoterapia hiperbárica (83% dos animais) de forma isolada, pois quando comparada com o grupo II isolado (67% dos animais) ainda sugere uma superioridade na formação calosa mais rápida ao término do período precoce. Não foram encontradas alterações nos parâmetros hematológicos com as intervenções utilizadas. Conclusões: A oxigenoterapia hiperbárica e o sulfato de condroitina-a associado ao sulfato de glucosamina, isoladas ou em associação promovem aumento do calo ósseo e não promovem alterações nos parâmetros hematológicos dos animais nos tempos estudados.

Proposta di sottotitolaggio del social movie italy in a day

The aim of this thesis is to analyse the main translating issues related to the subtitling of the Italian social movie Italy in a day into English: Italy in a day is a crowdsourced film, comprising a selection of video clips sent by ordinary people, showing occurrences of everyday life on a single day, October 26th, 2013. My dissertation consists of four chapters. The first provides a general overview of audiovisual translation, from the description of the characteristics of filmic products to a summary of the most important audiovisual translation modes; a theoretical framework of the discipline is also provided, through the analysis of the major contributions of Translations Studies and the multidisciplinary approach proposed by the scholar Frederic Chaume. The second chapter offers insight into the subtitling practice, examining its technical parameters, the spatial and temporal constraints, together with the advantages and pitfalls of this translation mode. The main criteria for quality assessment are also outlined, as well as the procedures carried out in the creation of subtitles within a professional environment, with a particular focus on the production of subtitles for the DVD industry. In the third chapter a definition of social movie is provided and the audiovisual material is accurately described, both in form and content. The creation of the subtitling project is here illustrated: after giving some information about the software employed, every step of the process is explained. In the final chapter the main translation challenges are highlighted. In the first part some text reduction techniques in the shift from oral to written are presented; then the culture-specific references and the linguistic variation in the film are analysed and the compensating strategies adopted to fill the linguistic and cultural gap are commented on and justified taking into account the needs and expectations of the target audience.

Rapid induction of remission in large vessel vasculitis by IL-6 blockade. A case series

OBJECTIVE: To evaluate the effect of IL-6 blockade using tocilizumab in inducing remission of arterial large vessel vasculitides (LVV). METHODS: Five consecutive patients with giant-cell arteritis (GCA) and two with Takayasu’s arteritis (TA) were treated by tocilizumab infusions (8 mg/kg). Tocilizumab was given every other week for the first month and once monthly thereafter. Clinical symptoms of disease activity, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level and glucocorticoid (GC) dosage necessary to maintain remission were prospectively assessed. MR angiography was performed to monitor local inflammation. RESULTS: Of the seven patients three were newly diagnosed and four showed GC resistance, i.e. GC could not be lowered to less than 7.5 mg/day. The mean follow-up time was 4.3 months (range 3–7 months). All patients achieved a rapid and complete clinical response and normalisation of the acute phase proteins. Remarkably, prednisone dosage could be reduced within 12 weeks to a mean of 2.5 mg/day (range 0–10 mg/day). No relapse and no drug-related side effects were noted. CONCLUSION: Collectively the data suggest that IL-6 blockade using tocilizumab qualifies as a therapeutic option to induce rapid remission in large vessel vasculitides.

Effect of the prolactin-release inhibitor quinagolide on lactating dairy cows

In most mammals, prolactin (PRL) is essential for maintaining lactation, and yet the short-term suppression of PRL during established lactation by bromocriptine has produced inconsistent effects on milk yield in cows and goats. To assess the effect of the long-term inhibition of PRL release in lactating dairy cows, 5 Holstein cows in early lactation received daily intramuscular injections of 1mg of the PRL-release inhibitor quinagolide for 9 wk. Four control cows received the vehicle (water) only. During the last week of the treatments, one udder half was milked once a day (1x) and the other twice a day (2x). Blood samples were harvested at milking in wk -1, 1, 4, and 8. The daily injections of quinagolide reduced milking-induced PRL release but not the basal PRL concentration. Quinagolide induced a faster decline in milk production, which was about 5.3 kg/d lower in the quinagolide-treated cows during the last 4 wk of treatment. During wk 9, the inhibition of milk production by quinagolide was maintained in the udder half that was milked 2x but not in the half milked 1x. Milk production was significantly correlated with the quantity of PRL released at milking. Quinagolide did not affect the release of oxytocin at milking. Serum concentration of insulin-like growth factor-1 was not affected by treatment or correlated with milk production. Serum concentrations of leptin and the calciotropic hormone stanniocalcin were not affected by the treatment. In conclusion, the chronic administration of the PRL-release inhibitor quinagolide decreases milk production in dairy cows. The effect is likely the result of the reduced release of milking-induced PRL and is modulated at the level of the gland by milking frequency.

Effects of dietary supplementation with synthetic vitamin D-3 and 25-hydroxycholecalciferol on blood calcium and phosphate levels and performance in laying hens

We investigated the effects of different dietary vitamin D regimen on selected blood parameters in laying hens. Supplementation with vitamin D-3 only was compared with a combination of vitamin D-3 and its metabolite 25-hydroxy-cholecalciferol (25(OH)D-3). Blood concentrations of total calcium, phosphate and 25 (OH)D-3 were determined. Four thousand one-day-old LSL chicks were split in two treatment groups and distributed to eight pens. The control group was given a commercial animal diet containing 2800 IU synthetic vitamin D-3 in the starter feed and 2000 IU synthetic vitamin D-3 in the pullet feed. The experimental group was fed the same commercial diet in which half the synthetic vitamin D-3 content had been substituted with 25(OH)D-3 (Hy center dot D (R)). At 18 weeks of age, pullets were transferred to the layer house. At the ages of 11, 18 and 34 weeks, between 120 and 160 blood samples were collected from both the control and the experimental groups, respectively. The experimental group had higher levels of 25 (OH)D-3 than the control group at all three ages. Serum calcium levels did not differ between the treatment groups at any age. With the onset of laying, calcium levels rose significantly. Whereas blood serum concentration at 18 weeks was 3 mmol/L in both treatment groups, it increased to 8.32 mmol/L in the control group and to 8.66 mmol/L in the experimental group at week 34. At weeks 11 and 34, phosphate was significantly lower in the experimental group. In conclusion, HyD (R) significantly affected serum phosphate and 25(OH)D-3 levels. No effects of (25(OH)D-3 supplementation on performance, shell quality and fractures of keelbones were found.

Effects of acupuncture and Chinese herbal medicine (Zhi Mu 14) on hot flushes and quality of life in postmenopausal women: results of a four-arm randomized controlled pilot trial

OBJECTIVE: The aim of this study was to evaluate the feasibility of a clinical trial investigating the effects of acupuncture (AP) and Chinese herbal medicine (CHM) on hot flushes and quality of life in postmenopausal women. METHODS: Forty postmenopausal women reporting at least 20 hot flushes per week were enrolled in a randomized controlled trial. They were randomly allocated to receive traditional Chinese medicine (TCM) AP, sham AP, verum CHM, or placebo CHM for 12 weeks. Follow-up assessment was conducted 12 weeks after intervention. Primary outcome measures included hot flush frequency and severity. As a secondary outcome measure, the severity of menopausal symptoms was assessed using the Menopause Rating Scale (MRS) II. RESULTS: TCM AP induced a significant decline in all outcome measures from pretreatment to posttreatment compared with sham AP (hot flush frequency, P = 0.016; hot flush severity, P = 0.013; MRS, P < 0.001). In the TCM AP group, a larger decrease in MRS scores persisted from pretreatment to follow-up (P = 0.048). No significant differences were noted between the verum CHM group and the placebo CHM group. Compared with the verum CHM group, there was a significant decrease in MRS scores (P = 0.002) and a trend toward a stronger decrease in hot flush severity (P = 0.06) in the TCM AP group from pretreatment to posttreatment. CONCLUSIONS: TCM AP is superior to sham AP and verum CHM in reducing menopausal symptoms, whereas verum CHM shows no significant improvements when compared with placebo CHM.

Effects of high-dose heroin versus morphine in intravenous drug users: a randomised double-blind crossover study

The purpose of this study is to evaluate the effects of high doses of injected opiates as prescribed maintenance in intravenous drugs users. This was accomplished via a randomised double-blind study with crossover at an outpatient clinic in Bern, Switzerland. The subjects were 39 patients with a long history of intravenous opioid use and persistent abuse despite treatment; they were randomly allocated to two groups. Group A was started on controlled injection of graduated doses of morphine up to a satisfying individual dose and was then switched as a double blind to heroin at a randomly determined day between week three and four. Subsequently this group was given heroin for the remaining two to three weeks of the study. Group B was started on heroin and was then switched to morphine in the same manner. Equipotent solutions of 3% morphine and 2% heroin were administered. The main outcome measures were clinical observations, structural interviews and self report of subjective experiences to assess the effects of the drugs. In 16 cases, the study had to be discontinued owing to severe morphine-induced histamine reactions. Thirteen participants in Group B presented these adverse reactions on the day of the switch-over. Full data were thus only obtainable for 17 participants. Average daily doses were 491 mg for heroin and 597 mg for morphine. The findings indicate that heroin significantly produced a lower grade of itching, flushing, urticaria and pain/nausea. A negative correlation between dose and euphoria was observed for both heroin and morphine. The authors concluded that as heroin produces fewer side effects it is the preferred high-dose maintenance prescription to morphine. The perceived euphoric effects are limited in both substances.

Comparative in vivo study on the healing qualities of four different presealed vascular prostheses

PURPOSE: The purpose of this article is to assess the healing qualities of presealed knitted polyester prostheses. METHODS: Thoracic aortic replacement was performed with grafts with four different coating materials-collagen (CP), albumin (AP), and two with gelatin (GP1/GP2)-in four groups of 15 pigs each. Two weeks, 6 weeks, and 6 months after operation, five pigs of each group were killed. Healing quality was assessed by morphometric analysis of the remaining coating, the extent of tissue ingrowth, and the thickness of the inner layer. RESULTS: The sealant was rapidly absorbed in all prostheses except for the AP (remaining coating at 2 weeks: GP1 22.1%, GP2 34.7%, and CP 68.0% vs AP 97.1% [p < 0.05]), remaining coating at 6 weeks: GP1/GP2 0% and CP 2.5% vs AP 76.7% (p < .01). At 6 months, remaining coating was only detectable in AP (21.5%). At 2 weeks the extent of tissue ingrowth ranged from 65.7% in GP1 and 75.3% in CP to 80% in GP2 versus 8.9% in AP (p < 0.05). There was a slow increase of tissue ingrowth until the sixth postoperative week (GP1 74.4%, GP2 85.0%, and CP 91.3% versus AP 19.6% [p < 0.01]). Thickness of the internal layer varied from 0.11 to 0.21 mm at 2 weeks in all grafts studied and from 1.02 mm (AP) and 1.28 mm (GP2) to 1.39 mm (GP1), versus 0.41 mm in the CP (p < 0.01) after 6 months of implantation. CONCLUSIONS: The type of coating significantly influences the healing properties of knitted polyester prostheses. When used for thoracic aortic replacement in pigs, AP coating clearly results in inferior healing compared with GP1/GP2 or CP impregnation, with digestion of the coating material and tissue ingrowth used as parameters. The thinnest internal layer was found in the CP prostheses, reflecting superior healing properties of this coating in the model studied.

Effects of intensive arm training with the rehabilitation robot ARMin II in chronic stroke patients: four single-cases

BACKGROUND: Robot-assisted therapy offers a promising approach to neurorehabilitation, particularly for severely to moderately impaired stroke patients. The objective of this study was to investigate the effects of intensive arm training on motor performance in four chronic stroke patients using the robot ARMin II. METHODS: ARMin II is an exoskeleton robot with six degrees of freedom (DOF) moving shoulder, elbow and wrist joints. Four volunteers with chronic (>or= 12 months post-stroke) left side hemi-paresis and different levels of motor severity were enrolled in the study. They received robot-assisted therapy over a period of eight weeks, three to four therapy sessions per week, each session of one hour.Patients 1 and 4 had four one-hour training sessions per week and patients 2 and 3 had three one-hour training sessions per week. Primary outcome variable was the Fugl-Meyer Score of the upper extremity Assessment (FMA), secondary outcomes were the Wolf Motor Function Test (WMFT), the Catherine Bergego Scale (CBS), the Maximal Voluntary Torques (MVTs) and a questionnaire about ADL-tasks, progress, changes, motivation etc. RESULTS: Three out of four patients showed significant improvements (p < 0.05) in the main outcome. The improvements in the FMA scores were aligned with the objective results of MVTs. Most improvements were maintained or even increased from discharge to the six-month follow-up. CONCLUSION: Data clearly indicate that intensive arm therapy with the robot ARMin II can significantly improve motor function of the paretic arm in some stroke patients, even those in a chronic state. The findings of the study provide a basis for a subsequent controlled randomized clinical trial.

Incidence, etiology and risk factors of neonatal seizures Harris County, Texas, 1992--1994

This study was conducted to determine the incidence and etiology of neonatal seizures, and evaluate risk factors for this condition in Harris County, Texas, between 1992 and 1994. Potential cases were ascertained from four sources: discharge diagnoses at local hospitals, birth certificates, death certificates, and a clinical study of neonatal seizures conducted concurrent with this study at a large tertiary care center in Houston, Texas. The neonatal period was defined as the first 28 days of life for term infants, and up to 44 weeks gestation for preterm infants.^ There were 207 cases of neonatal seizures ascertained among 116,048 live births, yielding and incidence of 1.8 per 1000. Half of the seizures occurred by the third day of life, 70% within the first week, and 93% within the first 28 days of life. Among 48 preterm infants with seizures 15 had their initial seizure after the 28th day of life. About 25% of all seizures occurred after discharge from the hospital of birth.^ Idiopathic seizures occurred most frequently (0.5/1000 births), followed by seizures attributed to perinatal hypoxia/ischemia (0.4/1000 births), intracranial hemorrhage (0.2/1000 births), infection of the central nervous system (0.2/1000 births), and metabolic abnormalities (0.1/1000 births).^ Risk factors were evaluated based on birth certificate information, using univariate and multivariate analysis (logistic regression). Factors considered included birth weight, gender, ethnicity, place of birth, mother's age, method of delivery, parity, multiple birth and, among term infants, small birth weight for gestational age (SGA). Among preterm infants, very low birth weight (VLBW, $<$1500 grams) was the strongest risk factor, followed by birth in private/university hospitals with a Level III nursery compared with hospitals with a Level II nursery (RR = 2.9), and male sex (RR = 1.8). The effect of very low birth weight varied according to ethnicity. Compared to preterm infants weighing 2000-2999 grams, non-white VLBW infants were 12.0 times as likely to have seizures; whereas white VLBW infants were 2.5 times as likely. Among term infants, significant risk factors included SGA (RR = 1.8), birth in Level III nursery private/university hospitals versus hospitals with Level II nursery (RR = 2.0), and birth by cesarean section (RR = 2.2). ^

Plasminogen activator inhibitor-1, monocyte chemoattractant protein-1, e-selectin and C-reactive protein levels in response to 4-week very-high-fructose or -glucose diets.

BACKGROUND/OBJECTIVES High intake of added sweeteners is considered to have a causal role in the pathogenesis of cardiometabolic disorders. Especially, high-fructose intake is regarded as potentially harmful to cardiometabolic health. It may cause not only weight gain but also low-grade inflammation, which represents an independent risk factor for developing type 2 diabetes and cardiovascular disease. In particular, fructose has been suggested to induce plasminogen activator inhibitor-1 (PAI-1) expression in the liver and to increase circulating inflammatory cytokines. We therefore aimed to investigate, whether high-fructose diet has an impact on PAI-1, monocyte chemoattractant protein-1 (MCP-1), e-selectin and C-reactive protein (CRP) concentrations in healthy humans. SUBJECTS/METHODS We studied 20 participants (12 males and 8 females) of the TUebingen FRuctose Or Glucose study. This is an exploratory, parallel, prospective, randomized, single-blinded, outpatient, hypercaloric, intervention study. The participants had a mean age of 30.9 ± 2.1 years and a mean body mass index of 26.0 ± 0.5 kg/m(2) and they received 150 g of either fructose or glucose per day for 4 weeks.Results:There were neither significant changes of PAI-1, MCP-1, e-selectin and CRP after fructose (n=10) and glucose (n=10) intervention nor treatment effects (all P>0.2). Moreover, we did not observe longitudinal associations of the inflammatory parameters with triglycerides, liver fat, visceral fat and body weight in the fructose group. CONCLUSIONS Temporary high-fructose intake does not seem to cause inflammation in apparently healthy people in this secondary analysis of a small feeding trial.

Efficacy of lead-in silibinin and subsequent triple therapy in difficult-to-treat HIV/hepatitis C virus-coinfected patients

OBJECTIVES: The efficacy of current hepatitis C virus (HCV) triple therapy, including a protease inhibitor, is limited in HIV/HCV-coinfected patients with advanced liver fibrosis and nonresponse to previous peginterferon-ribavirin. These patients have a low chance (only 30%) of achieving a sustained virological response (SVR) during triple therapy and cannot wait for next-generation anti-HCV drugs. In a pilot study, we investigated the efficacy of a lead-in therapy with silibinin before triple therapy in difficult-to-treat patients. METHODS: Inclusion criteria were HIV/HCV coinfection with advanced liver fibrosis and documented failure of previous peginterferon-ribavirin treatment. Intervention was lead-in therapy with intravenous silibinin 20 mg/kg/day for 14 days. Subsequently, peginterferon-ribavirin combined with telaprevir was initiated for 12 weeks, followed by peginterferon-ribavirin dual therapy until week 48 after initiation of triple therapy. The outcome measurements were HCV RNA after silibinin lead-in, at weeks 2, 4 and 12 of triple therapy, and SVR at week 24 after the end of treatment. RESULTS: We examined six HIV/HCV-coinfected patients (four infected with genotype 1a). All had fibrosis grade METAVIR ≥F3 and were on fully suppressive antiretroviral therapy. Mean HCV RNA decline after silibinin therapy was 2.6 log10 IU/mL (range 2-3 log10 IU/mL). Five of the six patients were virologically suppressed at weeks 2 and 4, and all six at week 12 of triple therapy. One experienced a viral breakthrough thereafter. Four of five patients (80%) showed an SVR 24. One patient had an SVR 12 but has not yet reached week 24. CONCLUSIONS: A lead-in with silibinin before triple therapy is highly effective and increases the probability of HCV treatment success in difficult-to-treat HIV/HCV-coinfected patients with advanced liver fibrosis and previous failure of peginterferon-ribavirin.
