Multimodal Strategies in Development.Predictive Value of early simultaneosgesture-speech comination

The present study investigates the predictive value of the early appearance of simultaneous pointing-speech combinations. An experimental task was used to obtain a communicative productive sample from nineteen children at 1;0 and 1;3. Infant’s communicative productions, in combination with gaze joint engagement patterns, were analyzed in relation to different social conditions. The results show a significant effect of age and social condition on infants’ communicative productions. Gesture-speech combinations seem to work as a strong communicative resource to attract the adult’s attention in social demanding communicative contexts. Gaze joint engagement was used in combination with simultaneous pointing-speech combinations to attract adults’ attention during social demanding conditions. Finally, the use of simultaneous pointing-speech combinations at 1;0 in demanding conditions predicted greater expressive vocabulary acquisition at 1;3 and 1;6. These results indicate that the use of gesture-speech combinations may be considered a significant step towards the early integration of language components.

Características do pasto e desempenho de novilhas em sistema silvipastoril e pastagem de braquiária em monocultivo

O objetivo deste trabalho foi avaliar as características do pasto e o desempenho de novilhas oriundas do cruzamento Holandês x Zebu, em sistema silvipastoril (SSP) e em monocultivo de braquiária (Urochloa decumbens). O delineamento experimental foi o de blocos ao acaso, com dois tratamentos: em monocultivo de braquiária; e o SSP, que apresentava faixas de braquiária consorciada com Stylosanthes guianensis, alternadas com faixas arborizadas. Os piquetes foram manejados sob lotação rotacionada, com 7 dias de ocupação e 35 e 49 dias de descanso, nas épocas chuvosa e seca, respectivamente. As características do pasto, o consumo e o ganho de peso não variaram com o sistema; porém, devido às reduções na quantidade e no valor nutritivo da forragem, apresentaram valores maiores na época chuvosa do que na época seca, respectivamente: massa de forragem pré-pastejo, 1.525 e 964 kg ha-1; teores de proteína bruta na gramínea, 9,3 e 8,2%; digestibilidade in vitro da matéria seca, 56,1 e 50,3%; consumo de matéria seca, 2,3 e 1,6% do peso vivo; ganho de peso de 625 e 242 g por dia por novilha. O sombreamento moderado no SSP não interferiu nas características do pasto, nem no consumo de forragem, nem no desempenho de novilhas leiteiras, quando comparado aos valores obtidos na pastagem de braquiária em monocultivo.

Mobilization of hemopoietic stem cells with high-dose methotrexate plus granulocyte-colony-stimulating factor in patients with primary central nervous system lymphoma.

BACKGROUND: High-dose therapy with autologous stem cell support after standard dose induction is a promising approach for therapy of primary central nervous system lymphoma (PCNSL). High-dose methotrexate (HD-MTX) is a standard drug for induction of PCNSL; however, data about the capacity of HD-MTX plus granulocyte-colony-stimulating factor (G-CSF) to mobilize hemopoietic progenitors are lacking. STUDY DESIGN AND METHODS: This investigation describes the data from stem cell mobilization and apheresis procedures after one or two cycles of HD-MTX for induction of PCNSL within the East German Study Group for Haematology and Oncology 053 trial. Eligible patients proceeded to high-dose busulfan/thiotepa after induction therapy and mobilization. RESULTS: Data were available from nine patients with a median age of 58 years. The maximal CD34+ cell count per microL of blood after the first course of HD-MTX was 13.89 (median). Determination was repeated in six patients after the second course with a significantly higher median CD34+ cell count of 33.69 per microL. Five patients required two apheresis procedures and in four patients a single procedure was sufficient. The total yield of CD34+ cells per kg of body weight harvested by one or two leukapheresis procedures was 6.60 x 10(6) (median; range, 2.68 x 10(6)-15.80 x 10(6)). The yield of CD34+ cells exceeded the commonly accepted lower threshold of 3 x 10(6) cells per kg of body weight in eight of nine cases. Even in the ninth, hemopoietic recovery after stem cell reinfusion was rapid and safe. CONCLUSION: HD-MTX plus G-CSF is a powerful combination for stem cell mobilization in patients with PCNSL and permits safe conduction of time-condensed and dose-intense protocols with high-dose therapy followed by stem cell reinfusion after HD-MTX induction.

Some pneumococcal serotypes are more frequently associated with relapses of acute exacerbations in COPD patients

Objectives: To analyze the role of the capsular type in pneumococci causing relapse and reinfection episodes of acute exacerbation in COPD patients. Methods: A total of 79 patients with 116 recurrent episodes of acute exacerbations caused by S. pneumoniae were included into this study (1995–2010). A relapse episode was considered when two consecutive episodes were caused by the same strain (identical serotype and genotype); otherwise it was considered reinfection. Antimicrobial susceptibility testing (microdilution), serotyping (PCR, Quellung) and molecular typing (PFGE/MLST) were performed. Results: Among 116 recurrent episodes, 81 (69.8%) were reinfections, caused by the acquisition of a new pneumococcus,and 35 (30.2%) were relapses, caused by a pre-existing strain. Four serotypes (9V, 19F, 15A and 11A) caused the majority (60.0%) of relapses. When serotypes causing relapses and reinfection were compared, only two serotypes were associatedwith relapses: 9V (OR 8.0; 95% CI, 1.34–85.59) and 19F (OR 16.1; 95% CI, 1.84–767.20). Pneumococci isolated from relapses were more resistant to antimicrobials than those isolated from the reinfection episodes: penicillin (74.3% vs. 34.6%, p,0.001), ciprofloxacin (25.7% vs. 9.9%, p,0.027), levofloxacin (22.9% vs. 7.4%, p = 0.029), and co-trimoxazole (54.3% vs. 25.9%, p,0.001). Conclusions: Although the acquisition of a new S. pneumoniae strain was the most frequent cause of recurrences, a third ofthe recurrent episodes were caused by a pre-existing strain. These relapse episodes were mainly caused by serotypes 9V and 19F, suggesting an important role for capsular type

A need for determination of arsenic species at low levels in cereal-based food and infant cereals. Validation of a method by LC-ICPMS.

The present study arose from the need to determine inorganic arsenic (iAs) at low levels in cereal-based food. Validated methods with a low limit of detection (LOD) are required to analyse these kinds of food. An analytical method for the determination of iAs, methylarsonic acid (MA) and dimethylarsinic acid (DMA) in cereal-based food and infant cereals is reported. The method was optimised and validated to achieve low LODs. Ion chromatography-inductively coupled plasma mass spectrometry (LC-ICPMS) was used for arsenic speciation. The main quality parameters were established. To expand the applicability of the method, different cereal products were analysed: bread, biscuits, breakfast cereals, wheat flour, corn snacks, pasta and infant cereals. The total and inorganic arsenic content of 29 cereal-based food samples ranged between 3.7-35.6 and 3.1-26.0 microg As kg-1, respectively. The present method could be considered a valuable tool for assessing inorganic arsenic contents in cereal-based foods.

Convenient synthesis of C75, an inhibitor of FAS and CPT1

C75 is a synthetic racemic α-methylene-γ-butyrolactone exhibiting anti-tumoral properties in vitro and in vivo as well as inducing hypophagia and weight loss in rodents. These interesting properties are thought to be a consequence of the inhibition of the key enzymes FAS and CPT1 involved in lipid metabolism. The need for larger amounts of this compound for biological evaluation prompted us to develop a convenient and reliable route to multigram quantities of C75 from easily available ethyl penta-3,4-dienoate 6. A recently described protocol for the addition of 6 to a mixture of dicyclohexylborane and nonanal followed by acidic treatment of the crude afforded lactone 8, as a mixture of cis and trans isomers, in good yield. The DBU-catalyzed isomerization of the methyl esters 9 arising from 8 gave a 10:1 trans/cis mixture from which the trans isomer was isolated and easily transformed into C75. The temporary transformation of C75 into a phenylseleno ether derivative makes its purification, manipulation and storage easier.

Field Evaluation of Cold In-Place Recycling of Asphalt Concrete, HR-303, Construction Report, 1990

There are still many vintage portland cement concrete (PCC) pavements, 18 ft wide (5.4 m), dating back to pre-World War II era in use today. Successive overlays have been placed to cover joints and to improve rideability. The average thickness of the existing asphalt cement concrete (ACC) along route E66 in Tama County, Iowa, was 6.13 in. (15.6 cm). The rehabilitation strategy called for widening the base using the top 3 in. (7.6 cm) of the existing ACC by a recycling process involving cold milling and mixing with additional emulsion/rejuvenator. The material was then placed into a widening trench and compacted to match the level of the milled surface. This project was undertaken to develop a rehabilitation methodology to widen these older pavements economically and to have a finished surface capable of carrying traffic with little or no additional work.

Intraoperative cerebral perfusion in geriatric patients

Background: It is unknown whether cerebral perfusion in geriatric and younger patients under general anaesthesia differs. Methods: We compared 2 groups of patients undergoing elective major non-cardiac surgery under standardized general anaesthesia (thiopental, sevoflurane, fentanyl, atracurium). Group 1: 18-40 yrs (n = 20), Group 2: >65 yrs (n = 37). Cerebral perfusion was investigated with transcranial Doppler and near-infrared spectroscopy (NIRS). Arterial blood pressure was monitored continuously with a Finapres device. Mx, an index allowing continuous monitoring of cerebrovascular autoregulation based on the changes in mean arterial blood pressure (MAP) and cerebral blood flow velocity was calculated. Data are shown as mean } SD. Results: MAP (86 } 9.6 vs 79 } 10.9 mm Hg, p = 0.02), end-tidal concentration of sevoflurane (1.9 } 0.3 vs 1.6 } 0.3%, p <0.01), and the cerebral tissue oxygenation index measured by NIRS (72 } 4 vs 68 } 5%, p = 0.01), were significantly lower in Group 2. The end-tidal concentration of O2 was significantly higher in Group 2 (46 } 4 vs 48 } 4% p = 0.04). There were no significant differences between Group 1 and 2 for cerebral blood flow velocity (41 } 10 vs 43 } 18 cm/s), end tidal CO2 (4.7 } 0.3 vs 4.6 } 0.3 kPa) and cerebrovascular autoregulation (Mx 0.42 } 0.2 vs 0.48 } 0.2). In Group 1 35% and in Group 2 43% of the patients had an index of autoregulation suggesting disturbed cerebrovascular autoregulation (p = n.s.). Conclusions: In elderly patients under general anaesthesia with sevoflurane the cerebral tissue oxygenation index was significantly lower than in younger patients despite higher end-tidal oxygen concentrations. Our data suggest subtle differences in cerebral perfusion between geriatric and younger
