Hypothyroidism induces several metabolic changes that allow understanding some physiopathological mechanisms. Under experimental hypothyroid conditions in rats, heart and kidney are protected against oxidative damage induced by ischemia reperfusion. An increased resistance to opening of the permeability transition pore seems to be at the basis of such protection. Moreover, glomerular filtration rate of hypothyroid kidney is low as a result of adenosine receptors-induced renal vasoconstriction. The ...

Acceptance of oral baits by dogs was evaluated in Guatemala. Eight bait matrix/attractant combinations were produced using commercial materials available in the United States. Two baits were produced using local materials in Guatemala. All baits included a plastic sachet that contained a placebo vaccine (water). Bait trials were conducted February-April, 2002, at five sites using 261 dogs. Bait acceptance ranged from 50.0% to 87.1%, and the combined proportion of sachets either swallowed or punctured ...

The present study demonstrates that when Acanthamoeba castellanii trophozoites are co-cultivated with isolated human corneas, the amoeba can be invasive and cause damage to the intact corneal epithelium without the requirement of previous corneal abrasion. After adhesion, A. castellanii trophozoites migrate between cells forming bumps on the corneal cell layers and reaching Bowman´s membrane in 3 h, although no evidence of cell damage was observed until the phagocytic process was detected. Likewise, ...

Thirteen patients with neurocysticercosis were studied and treated with flubendazole. Diagnostic procedures included computerized tomography (CT) and enzyme-linked immunosorbent assay. In 12 cases treatment with the drug led to clinical improvement. CT showed that some cysts regressed in size, and in two patients they disappeared. The treatment also lowered the antibody levels. The drug was well tolerated and no allergic reaction or other side effects were observed.

The biological component of soil is important for the maintenance and functioning of ecosystems. Currently there have been some studies on the diversity of soil biota and their role in key soil processes. Microorganisms are critical to the functioning of biological systems and the maintenance of life on the planet, since they participate in metabolic, ecological and biotechnological processes on which we depend for survival and for facing future challenges. Soil organisms maintain soil processes ...

The energy system in the Region of Aysén, Chile, is characterized by a strong dependence on fossil fuels, which account for up to 51% of the installed capacity. Although the implementation of waste-to-energy concepts in municipal waste management systems could support the establishment of a more fossil-independent energy system for the region, previous studies have concluded that energy recovery systems are not suitable from an economic perspective in Chile. Therefore, this work intends to evaluate ...

The purpose of this study was to estimate the prevalence of erectile dysfunction (ED) in Colombia, Ecuador, and Venezuela. A 49-item questionnaire was completed by 1946 men aged 40 years and older. The age-adjusted combined prevalence of minimal, moderate, and complete ED for all three countries was 53.4%, with 19.8% of all men reporting moderate to complete ED. Age was the variable most strongly linked to ED; the prevalence of complete ED increased markedly in men older than 79 y of age (31.9%) and ...

Non-cystic fibrosis bronchiectasis is a chronic structural lung condition that courses with recurrent infectious exacerbations that lead to frequent antibiotic treatment making this population more susceptible to acquire pathogens with antibiotic resistance. We aimed to investigate risk factors associated with isolation of multidrug-resistant pathogens in bronchiectasis exacerbations.A prospective observational study was conducted in two tertiary-care hospitals, enrolling patients when first exacerbation ...

Bronchiectasis (BE) is a chronic structural lung disease with frequent exacerbations, some of which require hospital admission though no clear associated factors have been identified. We aimed to evaluate factors associated with hospitalization due to exacerbations during a 1-year follow-up period. A prospective observational study was performed in patients recruited from specialized BE clinics. We considered all exacerbations diagnosed and treated with antibiotics during a follow-up period of 1 ...

We characterized the thermal behavior of a 65 nm bulk CMOS transistor, by measuring the self-heating effect (SHE) as a function of bias condition. We demonstrated that at a base temperature of 6.5 K the channel temperature of the transistor can increase up to several tens of kelvins due to power dissipation. The thermal behavior of the transistor is determined not only by the thermal response of the transistor itself but also by the thermal properties of the surroundings, i.e., source, drain, bulk, ...

We introduce experimental results of the I-V degradation characteristics of a Silicon SOI technology for RF applications when stressed under both; a 28 GHz and a DC stress input signals. Then we compare the effect of DC and RF stress on threshold voltage, transconductance, and drain current capability. We observe that reliability under RF stress is gate voltage dependent, and in some cases an improvement (“healing”) of the I-V characteristics is observed. A hypothetical explanation for the degradation/ ...
