Late-onset pompe’s disease (acid maltase deficiency, glycogen storage diseas e type II) is a slowly progressive myopathy caused by deficiency of acid α-glu cosidase. Current developments in enzyme replacement therapy require detailed kn owledge of the kind and severity of symptoms and the natural course of the disea se in the patient population.A detailed questionnaire covering the patients’med ical history and current situation was developed and information was gathered fr om 54 Dutch patients. The mean age of the participants was 48.6 ±15.6 *** first complaints started at a mean age of 28.1±14.3 years and were mostly rela ted to mobility problems and limb-girdle weakness. Fifty-eight percent of the adult patients indicated the presence of mild muscular symptoms during childhood . Twenty-eight percent of the patients waited > 5 years for the final diagnosis after the first visit to a physician for disease related complaints. At the tim e of questionnaire completion,48%of the study population used a wheelchair and 37%used artificial *** such as rising from an armchair,taking stairs or getting upright after bending over were difficult or impossible for m ore than two-thirds of the *** age at onset, the rate of disease pr ogression and the sequence of respiratory and skeletal muscle involvement varied substantially between patients. Seventy-six percent of the participants indica ted being troubled by fatigue and 46%by pain. This survey has mapped the age at onset, presenting symptoms, heterogeneity in progression and range of disease s everity in a large group of Dutch patients. We conclude that early manifestation s in childhood require proper attention to prevent unnecessary delay of the diag nosis. The follow-up of patients with late-onset pompe’s disease should focus on respiratory and limb-girdle muscle function, the capacity to perform daily activities, and the presentation of fatigue and pain.

The influence of supplementation with soybean hulls, wheat starch or pectin on fibre degradation of barley straw was studied in Rusitec when urea was the sole nitrogen supplement as the control. Supplementation with soybean hulls or pectin resulted in higher degradability of DM, om, NDF or ADF in which the values for soybean hull compared with urea was 61.1vs. 59.2％, 60.3vs. 58.3％, 57.3vs. 54.7％ and 54.9vs. 52.5％, successively (ppplementation with wheat starch did not show the stimulatory effect after 48h incubation. With the species of rumen microbes in the straw fibre observed under scanning electron microscope, the one of the stimulatory effects from soybean hull was the interaction of anaerobic fungi and cellulolytic bacteria and the effect from.pectin was the increase of cellulolytic bacterial number in straw fibre. That the urea and supplementation with soybean hull resulted in the high NH-N production might be attributed to the anaerobic fungi. Total VFA and acetic productionsupported the stimulatory effect of soybean hull and pectin. Although supplementation with the three carbohydrates increased the total outflow of amino acids and the amount of microbial N synthesis, their efficiency of microbial N on kg Dom was lower than that of urea. Supplementation with soybean hull or pectin increased the number of total microbes but did not increase the number of cellulytic bacteria in the effluent from their own fermenter using most-probable-number procedures. The lower N degradability of barley straw resulted from the supplementation with the three carbohydrates indicates the adhesion of cellulolytic bacteria to the straw fibre.

Objective To compare a short and long interval between hCG administra tion and IUI after superovulation for the treatment of infertility. Design prospective, r andomized clinical trial. Setting University hospital-based fertility clinic. p atient(s) patients planning superovulation and IUI for the treatment of infertil ity. Intervention(s) patients with ≥2 years of infertility enrolled for superov ulation and IUI treatment were randomized to IUI after a short (32-34-hour) or long (38-40-hour) interval after hCG injection. Superovulation was accomplish ed with hMG or recombinant FSH, with dose adjustment until the maturation of two to five follicles, at which time hCG was given. Sperm was prepared with a gradi ent centrifugation technique, with IUI performed high up in the uterine fundus. Main outcome measure(s) pregnancy rates. Result(s) Of the 348 patient cycles randomized, 270 treatment cycles were initiated. Eighty -one initiated cycles were canceled, leaving 189 completed randomized cycles fr om 75 patients for analysis. pregnancy rates were not significantly different be tween groups. There were pregnancies in 20 of the 96 short hCG-IUI interval cyc les (21%) and in 14 of the 93 long hCG-IUI interval cycles (15%) (odds ratio = 0.673, 95%confidence interval 0.297-1.518). Conclusion( s) pregnancy rates a re the same after superovulation therapy whether IUI is done after a short or a long interval after hCG injection.

To develop an improved method of reusing poly(ethylene terephthalate) (pET) waste in the production chain, it was chemically modified with pentaerythritol (pENTE), resulting in pET/pENTE (60/40) oligomer. This was added to petroleum asphalt cement (CAp) in different proportions—5, 10 and 20 wt%—as a modifier of bitumen characteristics. The mixture was evaluated by thermogravimetry (TG/DTG), differential scanning calorimetry (DSC), infrared spectroscopy (FT-IR), optical microscopy (om) and the adhesion-peel test. The oligomer enhanced substantially the asphalt thermal stability-Tonset. om images showed strong compatibility between components and pET’s amorphization. pET oligomer increased CAp’s wettability and the mixture presented cohesive fracture through the peel test. The mixture has excellent potential as paving material.

The objective of this work was to develop a more and better understanding of the strength developing in clay-andesite fired brick. The purpose was to improve the quality of the clay bricks that are handmade in the southern region of Ecuador to make them suitable for more widespread use in the local construction industry. To achieve our goal, we first physically, chemically, and mechanically characterized the “clayey” and “sandy” materials used in the fabrication of handmade bricks in the region. Second, the optimal mixture (om): the optimal proportion between the amounts of “clayey” and “sandy” material was sought. Third, clay bricks were prepared using the om, baked at 950°C, and characterized. In addition, bricks produced by regional artisans were characterized, and the results were compared with the results obtained for the bricks prepared using the om. Our data reveal that the optimal mixture is 50% “clayey” material and 50% “sandy” material and that with this mixture, an average improvement in brick quality of 300% can be achieved;thus, the use of the om makes it possible to expand the use of these bricks in the local construction industry and enables an environmentally friendly production process by reducing the intensive exploitation of regional clay deposits. This improvement is achieved by virtue of the anorthite enrichment that occurs in the solid solution, which results from the evolution of andesine. The anorthite contributes to the formation of a stronger matrix among the different grains of the material. Conditions are favorable for this enrichment process to occur when “sandy” materials with high contents of andesite, which is common in Ecuadorian soils, are used.

Objective: To study whole-brain MR measures derived from diffusion tensor i maging and magnetization transfer imaging(MTI) for the in vivo assessment of cum ulative neuropathologic changes in HIV and to evaluate the quantitative imaging strategies with respect to cognitive status measures including the severity of d ementia and the degree of impairment in specific cognitive domains including att ention, memory, constructional abilities, and motor speed. Methods: Quantitative whole-brain measurements, including fractional anisotropy (FA), apparent diff usion coefficient (ADC), and magnetization transfer ratio (MTR), were derived fr om histograms and compared in HIV and control participants. Relationships betwee n the MR and cognitive status measures were examined. Results: Wholebrain FA and MTR were reduced in patients with HIV and correlated with dementia severity. Wh ole-brain MTR and ADC were correlated with psychomotor deficits. Evaluation of relationships between the studied MR measures indicated a correlation between A DC and MTR; FA was not correlated with either ADC or MTR. Conclusions: Findings from this investigation support the use of quantitative whole-brain MR measure s for evaluation of disease burden in HIV. Reductions in whole-brain fractiona l anisotropy and magnetization transfer ratio (MTR) distinguished HIV and contro l subjects, and these measures were associated with dementia severity. Relations hips were identified between whole-brain MTR and apparent diffusion coefficien t and psychomotor deficits. Combining these quantitative strategies in neuroimag ing examinations may provide more comprehensive information concerning ongoing c hanges in the brains of HIV patients.
