Wolbachia has deeply shaped the ecology and evolution of many arthropods, and interactions between the two partners are a continuum ranging from parasitism to mutualism. Non-dispersing queens of the termite Cavitermes tuberosus are parthenogenetically produced through gamete duplication, a mode of ploidy restoration generally induced by Wolbachia. These queens display a bacteriome-like structure in the anterior part of the mesenteron. Read More

The interleukin-1 (IL-1) signaling pathway plays a vital role in multiple mechanisms associated with myocardial ischemia-reperfusion (I/R) injury, including inflammation and apoptosis. An IL-1 receptor antagonist (IL-1Ra) can block IL-1 by competitive binding to the IL-1 receptor type I (IL-1RI) and thus may provide a cardioprotective effect. In the present investigation, we determined whether exogenous administration of recombinant human IL-1Ra (rhIL-1Ra) provides a protective role against myocardial I/R injury. Read More

The anterior thalamic nuclei are important for spatial and episodic memory, however, surprisingly little is known about the status of these nuclei in neurological conditions that present with memory impairments, such as Down syndrome. We quantified neurons and glial cells in the anterior thalamic nuclei of four older patients with Down syndrome. There was a striking reduction in the volume of the anterior thalamic nuclei and this appeared to reflect the loss of approximately 70% of neurons. Read More

Reconstruction of the orbital rim and floor following tumor excision is traditionally performed with bone grafts, vascularized grafts, or free flaps. The authors describe a case of an osteosarcoma of the maxillary sinus and a second case of an ossifying fibroma of the orbital floor, both of which required reconstruction of the orbital floor and rim. In both of these cases, reconstruction of the orbital floor and rim was performed with a titanium implant whose anterior portion was bent inferiorly to recreate the orbital rim. Read More

Intracortical bone porosity is a key microstructural parameter that determines bone mechanical properties. While clinical MRI visualizes the cortical bone with a signal void, ultrashort echo time (UTE) MRI can acquire high signal from cortical bone, thus enabling quantitative assessments. Magnetization transfer (MT) imaging combined with UTE-MRI can indirectly assess protons in the bone collagenous matrix, which are inversely related to porosity. Read More

Exudativory, the consumption of gums, is an obligate or a facultative dietary niche for some primates and marsupials. Exudativory has been cited as a dietary niche that may have been present in early primates, so finding a dental signature for exudativory is highly desirable. The present study combines exudativorous lorisoids (galagos and lorises) into one sample to compare to closely related, non-exudativorous lorisoids to search for a consistent dental signature of exudativory.

Intermediate mesoderm (IM) is the strip of tissue lying between the paraxial mesoderm (PAM) and the lateral plate mesoderm that gives rise to the kidneys and gonads. Chick fate mapping studies suggest that IM is specified shortly after cells leave the primitive streak and that these cells do not require external signals to express IM-specific genes (James and Schultheiss, 2003). Surgical manipulations of the chick embryo, however, revealed that PAM-specific signals are required for IM differentiation into pronephros - the first kidney (Mauch et al. Read More

Treatment of coronary artery aneurysms (CAAs) can either take the way of a close regular follow up with antiplatelet and anticoagulation therapy, percutaneous coronary intervention with possible stenting, or reach the extent of doing coronary artery bypass grafting. The severity of coexistent coronary artery stenosis, symptomatology, embolization to distal coronary beds, and increasing measurements over time are key players to decide whether to proceed with surgery in patients with CAAs. < (i) Coronary artery aneurysms (CAAs) are defined as luminal dilation 50% larger than that of the adjacent reference segment.
