Anomalous coronary origin: From suspicion to surgical revascularization

Congenital anomalies of the coronary arteries are uncommon and can present a diagnostic challenge. The authors present the case of a patient with recurrent chest pain during exertion admitted for acute coronary syndrome. Coronary angiography revealed no coronary lesions but showed that the right coronary artery originated from the anterolateral aortic wall, above the sinuses of Valsalva, leading to suspicion of...

Diagnóstico Pré-Natal das Anomalias do Tracto Urinário e Valor da Cistografia M...

A utilização sistemática da cistouretrografia miccional, no âmbito da investigação pós-natal das anomalias fetais do aparelho urinário, é controversa. A possibilidade de diagnosticar refluxo vesico-ureteral (RVU) antes de surgir infecção urinária é aliciante pela influência que pode ter na história natural da nefropatia do refluxo. Neste artigo, partindo de uma série de 116 casos de anomalia fetal do aparelho u...

Human spermatogenic failure purges deleterious mutation load from the autosomes...

Gonadal failure, along with early pregnancy loss and perinatal death, may be an important filter that limits the propagation of harmful mutations in the human population. We hypothesized that men with spermatogenic impairment, a disease with unknown genetic architecture and a common cause of male infertility, are enriched for rare deleterious mutations compared to men with normal spermatogenesis. After assaying...

Neudesin is involved in anxiety behavior : structural and neurochemical correlates

Neudesin (also known as neuron derived neurotrophic factor, Nenf) is a scarcely studied putative non-canonical neurotrophic factor. In order to understand its function in the brain, we performed an extensive behavioral characterization (motor, emotional, and cognitive dimensions) of neudesin-null mice. The absence of neudesin leads to an anxious-like behavior as assessed in the elevated plus maze (EPM), light/d...

Quality Management practices, absorptive capacity and innovation performance

Quality Management practices (QMP) are a potentially useful tool for increasing a company’s innovation performance. However, the empirical evidence regarding the impact of QMP on innovation performance has been mixed. The purpose of this study is to extend understanding of the impact of QMP on innovation performance by investigating the mediating effect of absorptive capacity on this relationship. A proposed re...

Experimental characterization of the structural response of adobe arches

Earth was one of the first construction materials used by mankind and has been used as a building material since ancient times until the present days. Its qualities related to thermal comfort, low cost or simple construction techniques have contributed to such a long tradition throughout the world with several different architectural expressions, integrating the culture and history of each region. With the wide...

Acute Bivalvular Left-Sided Methicillin-Resistant Staphylococcus Aureus Endocar...

Infective endocarditis (IE) is now rare in developed countries, but its prevalence is higher in elderly patients with prosthetic valves, diabetes, renal impairment, or heart failure. An increase in health-care associated IE (HCAIE) has been observed due to invasive maneuvers (30% of cases). Methicillin-resistant Staphylococcus aureus (MRSA) and Enterococcus are the most common agents in HCAIE, causing high mort...
