Animals requiring purposeful movement for survival are endowed with mechanoreceptors, called proprioceptors, that provide essential sensory feedback from muscles and joints to spinal cord circuits, which modulates motor output. Despite the essential nature of proprioceptive signaling in daily life, the mechanisms governing proprioceptor activity are poorly understood. Here, we identified nonredundant roles for two voltage-gated sodium channels (Nas), Na1.

Since their original proposal in 2008, a number of broadly distributed flavoprotein systems catalyzing electron bifurcation have been identified that play key roles in the bioenergetics of anaerobic bacteria and archaea. While the overall thermodynamics of flavin-based electron bifurcation are now quite well-understood, the same cannot be said of their kinetic behavior. The present account represents a summary of results obtained with several electron-electron bifurcating systems, shamelessly focusing on work done in the authors' laboratory.

The human lung is confronted daily with thousands of microbial invaders reaching the lower respiratory tract. An efficient response by the resident type 1 and type 2 alveolar epithelial cells (AECs) and alveolar macrophages (AMs) cells during the early hours of innate immunity is a prerequisite to maintain a non-inflammatory state, but foremost to rapidly remove harmful substances. One such human-pathogenic invader is the opportunistic fungus Aspergillus fumigatus.

Cosmetic procedures are a trending topic on social networks. Many users share their experiences and knowledge but also promote procedures whose effectiveness and validity have not been proven, making them seem effective in the collective imagination through the viral effect they generate. Here, we describe a second-surface-degree burn all over the breast print caused by a non-standard aesthetic procedure popularized on social networks: the PlasmaPen Fibroblast (Sefton, United Kingdom).

Germination is the fundamental process whereby fungi transition from the dormant and stress resistant spores into actively replicating cells such as hyphae. Germination is essential for fungal colonization of new environments and pathogenesis, yet this differentiation process remains relatively poorly understood. For filamentous fungi, the study of germination has been limited by the lack of high-throughput, temporal, low cost, and easy-to-use methods of quantifying germination.

Article Synopsis
  • Recent reports suggest some strains of a common bacterium have shown reduced susceptibility to antibiotics, but the significance of this resistance is uncertain due to varying testing methods.
  • The EUCAST has proposed a standardized method for antibiotic susceptibility testing, which this study applied to evaluate the effectiveness of 11 antibiotics on 347 poultry isolates.
  • Findings indicated that all poultry strains were sensitive to most antibiotics, with only one strain showing resistance to benzylpenicillin, confirming previous studies that antibiotic sensitivity in food-related populations remains stable.

Cancer in Mexico is a major public burden for which rates are expected to increase over time. In settings like Mexico, much potential for reduction through cancer prevention efforts remains unrealized, due in part, to a lack of formal cancer prevention and control training and career opportunities. We trained a cadre of instructors to deliver a pilot cancer prevention education program for oncology professionals and leaders.

A serous cystic tumor is a rare entity that has a benign course. Its imaging characteristics, such as the presence of multiple cysts with or without nodular enhancement, can simulate other cystic or solid lesions of the pancreas. Identification of the enhancing scar with punctate calcifications on computed tomography (CT) or magnetic resonance imaging (MRI) may be a distinctive finding suggesting this diagnosis.
