Researchers evaluating voice disorder interventions currently have a plethora of voice outcome measurement tools from which to choose. Faced with such a wide choice, it would be beneficial to establish a clear rationale to guide selection. This article reviews the published literature on the three main areas of voice outcome assessment: (1) perceptual rating of voice quality, (2) acoustic measu...

The genus Pyrochlora Warren is revised and three new species are described: P. motilonia, sp. nov. from Costa Rica and Nicaragua, P. kuklase, sp. nov. from mountainous Ecuador, and P. vogli, sp. nov. from Northern Venezuela. Wings pattern and genitalic structures of all five species are described and illustrated.

Syrphidae is one of the most speciose families of true flies, with more than 6,100 described species and worldwide distribution. They are important for humans acting as crucial pollinators, biological control agents, decomposers, and bioindicators. One third of its diversity is found in the Neotropical Region, but the taxonomic knowledge for this region is incomplete. Thus, taxonomic revisions ...

Stable isotope analysis in mysticete skin and baleen plates has been repeatedly used to assess diet and movement patterns. Accurate interpretation of isotope data depends on understanding isotopic incorporation rates for metabolically active tissues and growth rates for metabolically inert tissues. The aim of this research was to estimate isotopic incorporation rates in blue whale skin and bale...

We investigate the importance of the social context for people’s voluntary contributions to a national park in Costa Rica, using a natural field experiment. Some subjects make actual contributions while others state their hypothetical contribution. Both the degree of anonymity and provided information about the contributions of others influence subject contributions in the hypothesized directio...

Chronic necrotizing pulmonary aspergillosis is one of the forms of pulmonary aspergillosis typically found in mildly immunocompromised patients. We report the case of a female patient with complaints of chronic productive cough, fever and asthenia. She reported previous corticosteroid use. Computed tomography of the chest revealed consolidation with interposed cavitation in the right upper lobe...

We present the case of a 70-year-old woman with emphysematous cystitis. She was a diabetic patient and she was on chemotherapy treatment for a breast cancer. She complaint of severe asthenia and pain in her right lower extremity, but no fever or urinary symptoms. A computed tomography (CT) scan was suggestive of severe emphysematous cystitis. Emphysematous cystitis is a rare clinically entity, ...

Adaptation to interval normobaric hypoxia has been demonstrated to provide beneficial results in a wide spectrum of diseases and health-related conditions including: primary hypercholesterolemia, essential hypertension, ischemic heart disease (stable angina of effort and rehabilitation after myocardial infarction), neurocirculatory asthenia, idiopathic stress disorders of cardiac rhythm, bronch...
