In mice persistently infected with lymphocytic choriomeningitis virus (LCMV), the parenchymatous organs contain infiltrates of mononuclear cells, the sizes and numbers of which vary between strains and become more numerous and extensive when the animals grow older. Histologically, these were found to possess a tissue-like structure, and by use of immunohistologic procedures they were shown to c...
Copulation duration varies considerably across species, but few comparative studies have examined factors that might underlie such variation. We examined the relationship between copulation duration (prior to spermatophore transfer), the complexity of titillators (sclerotized male genital contact structures), spermatophore mass and male body mass across 54 species of bushcricket. Using phylogen...
There has been a recent burst of studies of the function of genitalia, many of which share several important shortcomings. Given that further studies on this topic are likely (there are probably millions of species showing rapid genital divergence), I discuss the studies critically to promote clear formulation of hypotheses and interpretation of results in the future. I also emphasize some poss...
Several signaling pathways work together, via a protein called Amotl2a, to establish the size and shape of a zebrafish sense organ primordium.
We have isolated a Drosophila mutant where the lateral parts of the notum are completely naked, leaving unaffected a median stripe of hairs. This mutation, iroquois (iro), defines a new gene which maps at 69D. We show that, in the presumptive lateral notum of mutant discs, sense organ precursor cells fail to form and the proneural gene scute is not expressed. The expression of a reporter gene i...
Although rare, complications can arise during the establishment of pneumoperitoneum during laparoscopic surgery. These include injury to blood vessels, hollow viscera, solid organs, and CO2 embolism. We report a case of trauma to the liver following the insertion of a Veress needle causing CO2 embolism during laparoscopic adrenalectomy. Opening pressures on insertion were high. Respiratory and ...
Solid organ transplantation is encumbered by an increasing number of waitlisted patients unrequited by the current organ supply. Preclinical models suggest that advances in deceased donor management and treatment can increase the quantity and quality of organs available for transplantation. However, the science of donor intervention and the execution of high quality, prospective, multi-center, ...
Previously we observed that neural cell adhesion molecule (NCAM) deficiency in beta tumor cells facilitates metastasis into distant organs and local lymph nodes. Here, we show that NCAM-deficient beta cell tumors grew leaky blood vessels with perturbed pericyte-endothelial cell-cell interactions and deficient perivascular deposition of ECM components. Conversely, tumor cell expression of NCAM i...
