We undertook a systematic evaluation of the prognostic value of numerous histologic factors in 165 radical cystectomies (RC) of patients with invasive urothelial carcinoma who underwent surgery after neoadjuvant chemotherapy (NAC). Tumor regression grade (TRG) and therapy-related stromal and epithelial changes were also recorded. Locally advanced disease (≥pT2 and/or pN+) was present in 64% of patients, 22% had no evidence of residual carcinoma (pT0+pN0) and 28% had no evidence of residual muscle invasive carcinoma (≤pT1+N0)...

Switchgrass (Panicum virgatum L.) is a sustainable cellulosic energy crop with high biomass yield on marginal soils. Tillering, an important agronomic characteristic related to biomass production in gramineous plants, is regulated by complex interacting factors, such as plant hormones. Strigolactones (SLs) comprise a novel class of plant hormones that inhibit shoot branching. The MORE AXILLARY GROWTH2 (MAX2)/DWARF 3 (D3)/RAMOSUS (RMS4) genes encode proteins involved in the SL signaling pathway in various plants...

Leaves are essential organs for plants. We previously identified a functional gene possibly encoding a component of the SWI/SNF complex named LFR (Leaf and Flower Related) in Arabidopsis thaliana. Loss-of-function mutants of LFR displayed obvious defects in leaf morphogenesis, indicating its vital role in leaf development. Here an allelic null mutant of ASYMMETRIC LEAVES2 (AS2), as2-6, was isolated as an enhancer of lfr-1 in petiole length, vasculature pattern and leaf margin development. The lfr as2 double mutants showed enhanced ectopic expression of BP than each of the single mutant, which is consistent with their synergistic genetic enhancement in multiple BP-dependent development processes...

The genus Circovirus includes one of the most relevant infectious agents affecting domestic pigs, Porcine circovirus type 2 (PCV-2). The wild boar susceptibility to this pathogen has also been demonstrated although the actual epidemiological role of wild populations is still debated. In recent times, a new circovirus, Porcine circovirus type 3 (PCV-3), has been discovered and reported in the presence of several clinical conditions. However, no information is currently available about PCV-3 circulation and prevalence in wild boar...

Animal models of mild traumatic brain injury (mTBI) provide opportunity to examine the extent to which dietary interventions can be used to improve recovery after injury. Animal studies also suggest that matrix metalloproteinases (MMPs) play a role in tissue remodeling post-TBI. Because dietary zinc (Zn) improved recovery in non-blast mTBI models, and the MMPs are Zn-requiring enzymes, we evaluated the effects of low- and adequate Zn diets on MMP expression and behavioral responses, following exposure to a single blast...

Partial nephrectomy (PN) is the preferred surgical treatment for T1 renal tumors whenever technically feasible. When properly performed, it allows preservation of nephron mass without compromising oncologic outcomes. This reduces the postoperative risk of renal insufficiency, which translates into better overall survival for the patients. PN can be technically challenging, because it requires the surgeon to complete the tasks of tumor excision, hemostasis and renorrhaphy, all within an ischemic time of preferably below 30 minutes...
