Aliesterase no sôro de alguns animais de laboratório

A esterase, aliesterase, foi determinada no sôro de 38 ratos de ambos os sexos, 6 hamsters, 34 cobaias e S coelhos, pela técnica de Huggins e Lapides. Os resultados obtidos para os machos e fêmeas foram tabelados em separado. As fêmeas apresentaram uma esterasemia maior que os machos, com uma média global de 11.6 U/ml ± 4.01 e um erro padrão de 0.83 enquanto que para os machos a média foi de 6.9 U ml ± 0.99 com um erro padrão de 0.26. A significância calculada pclo t foi de 4.4 Isto demonstra a interferência da aliesterase na produção ou no metabolismo dos estrogênios. Os valores médios encontrados para as cobaias foram 4.50 U/ ml ± 0.15, com um êrro padrão de 0.036 para as fêmeas e 4.28 U / ml ± 0.30 com um êrro padrão de 0.073 para os machos, sendo a significância (t) de 2.6. Para os coelhos (machos) a média foi de 4.41 U / ml ± 0.16, com um erro padrão de 0.058 enquanto para os hamsters os valores foram de 4.01 U/l ± 0.085, êrro padrão de 0.049 para os machos e 3.81 U/ml ± 0.227, êrro padrão de 0.133 para as fêmeas. Os animais castrados mostram uma diminuição progressiva da esterase no sôro, enquanto que nos castrados e tratados com estrogênios, êstes valores atingem o teôr normal. Os resultados obtidos nestes casos serão objeto de publicação ulterior.

Alzinar amb marfull o pineda?: estudi comparatiu de 6 zones geobotàniques del parc del Castell de l'Oreneta

S’ha estudiat la vegetació actual del parc de l'Oreneta, l’únic de Barcelona en el qual es conserva en part la vegetació natural que hi havia abans de la seva destinació com a parc. L’objectiu és veure com l'impacte antròpic ha modificat la que segurament era la vegetació natural de la zona - un alzinar amb marfull empobrit- per una pineda de pi blanc. A més, s’analitza les diferents adaptacions de la vegetació del parc als factors del biòtop, i molt en particular del marfull i l'aladern. S’ha començat estudiant els factors ambientals propis del parc. Posteriorment, s’ha dividit el biòtop del parc de l'Oreneta en sis zones de vegetació amb característiques específiques estudiant-ne les espècies existents, els índexs de diversitat de cada zona, l'abundància de les espècies, etc.

Full Tècnic. Conreus Extensius. Comarques de Girona, núm. 6 (2007)

Es presenta un resum dels resultats dels assaigs d’avaluació de varietats de blat de moro de cicle 700 i 600, obtinguts en la zona litoral de Girona, en el marc de la Xarxa d’Experimentació de Varietats de l’IRTA. S’han assajat híbrids convencionals i transgènics derivats del MON810, que incorporen resistència als barrinadors. Amb els resultats de quatre anys d’assaig han destacat principalment les varietats HELEN, ELEONORA, TIETAR, PR32R42, ASTURIAL i PR33P66, sense diferències significatives entre elles. Les varietats transgèniques s’han assajat un màxim de tres anys havent mostrat algunes d’elles una alta productivitat. Entre aquestes han destacat PR32P76, DKC6575, PR33P67 i HELEN Bt, si bé sense diferències significatives amb el testimoni ELEONORA. També amb els resultats de tres anys d’assaig cal remarcar la varietat de blat de moro convencional PR32W86, que ha mostrat un nivell productiu similar a les millors transgèniques. Amb només dos anys d’assaig ha destacat principalment la varietat transgènica BELES SUR.

Pelvic floor dysfunction 6 years post-anal sphincter tear at the time of vaginal delivery.

INTRODUCTION AND HYPOTHESIS: This study aims to estimate fecal, urinary incontinence, and sexual function 6 years after an obstetrical anal sphincter tear. METHODS: Among 13,213 women who had a vaginal delivery of a cephalic singleton at term, 196 women sustained an anal sphincter tear. They were matched to 588 controls. Validated questionnaires grading fecal and urinary incontinence, and sexual dysfunction were completed by the participants. RESULTS: Severe fecal incontinence was more frequently reported by women who had sustained an anal sphincter tear compared to the controls. Women with an anal sphincter tear had no increased risk of urinary incontinence, but reported significantly more pain, difficulty with vaginal lubrication, and difficulty achieving orgasm compared to the controls. A fetal occiput posterior position during childbirth was an independent risk factor for both severe urinary incontinence and severe sexual dysfunction. CONCLUSIONS: Fecal incontinence is strongly associated with an anal sphincter tear. A fetal occiput posterior position represents a risk factor for urinary incontinence and sexual dysfunction.

Compartmentalized Cerebral Metabolism of [1,6-(13)C]Glucose Determined by in vivo (13)C NMR Spectroscopy at 14.1 T.

Cerebral metabolism is compartmentalized between neurons and glia. Although glial glycolysis is thought to largely sustain the energetic requirements of neurotransmission while oxidative metabolism takes place mainly in neurons, this hypothesis is matter of debate. The compartmentalization of cerebral metabolic fluxes can be determined by (13)C nuclear magnetic resonance (NMR) spectroscopy upon infusion of (13)C-enriched compounds, especially glucose. Rats under light α-chloralose anesthesia were infused with [1,6-(13)C]glucose and (13)C enrichment in the brain metabolites was measured by (13)C NMR spectroscopy with high sensitivity and spectral resolution at 14.1 T. This allowed determining (13)C enrichment curves of amino acid carbons with high reproducibility and to reliably estimate cerebral metabolic fluxes (mean error of 8%). We further found that TCA cycle intermediates are not required for flux determination in mathematical models of brain metabolism. Neuronal tricarboxylic acid cycle rate (V(TCA)) and neurotransmission rate (V(NT)) were 0.45 ± 0.01 and 0.11 ± 0.01 μmol/g/min, respectively. Glial V(TCA) was found to be 38 ± 3% of total cerebral oxidative metabolism, accounting for more than half of neuronal oxidative metabolism. Furthermore, glial anaplerotic pyruvate carboxylation rate (V(PC)) was 0.069 ± 0.004 μmol/g/min, i.e., 25 ± 1% of the glial TCA cycle rate. These results support a role of glial cells as active partners of neurons during synaptic transmission beyond glycolytic metabolism.
