Placing these issues in a coherent comparative perspective, I argue that although the use of TSR snails may face similar technical, democratic and diplomatic challenges, some of the concerns over gene-drive mosquitoes may not apply to gene-drive snails, proposing a theory that community consent will be no harder and possibly easier to obtain for TSR snails than the experience with GM mosquitoes. In the future, these observations may help public health practitioners and policy makers in effective communication with communities on issues regarding the use of TSR snails to interrupt schistosomiasis transmission, especially in sub-Saharan Africa.TiO2-PILCs and iron-doped TiO2-PILCs were employed in order to destroy toxic microcystin-LR in the presence of H2O2 under the UV light. While less than 5% of the initial microcystin-LR and TOC disappeared in 240 min with the TiO2-PILCs, almost complete conversion of microcystin-LR could be achieved in 180 min on the 10 wt% iron-doped TiO2-PILC-A. On the exterior surface of the iron-doped TiO2-PILCs were mainly located iron particles which had nano-sized diameter and Fe2+/Fe3+ cations together. Through Fenton-type oxidation on iron particles with H2O2, the big microcystin-LR molecules were converted primarily into smaller intermediate organic molecules of hydrocarbons, carboxylic acids and organic amines. The smaller intermediate molecules were believed to be diffused into the pores of the iron-doped TiO2-PILCs and to be further mineralized into CO2 and H2O through the action of photocatalysis on the TiO2 pillars. However, complete conversion of TOC could not be obtained due to the iron particle deactivation. XPS, TPO and TEM studies showed the continuous accumulation of carbonaceous materials onto the surface of iron particles.A captive, adult female Brent goose (Branta bernicla) with a history of severe feather picking by its mate, was presented with 0.5-2.5 cm skin nodules on the head and neck. Histologic examination revealed a well-delineated dermal mass that surrounded an intact feather follicle and was composed of lakes of proteinaceous fluid and fibrin with scattered foamy macrophages and multinucleate giant cells. No bacteria or fungi were identified with histology, microbial culture, or PCR. Sterile panniculitis is an infrequent finding in animals and traumatic panniculitis is rarely sterile.Feline mammary tumors are usually malignant and aggressive carcinomas. Most cases are simple monophasic carcinomas (1 epithelial population), and additional phenotyping is usually not needed. In this study, we describe 10 malignant mammary tumors from 9 female cats that had unusual histomorphology they appeared biphasic, with 2 distinct cell populations. learn more Initially, they were morphologically diagnosed as either carcinosarcoma (1/10) or malignant pleomorphic tumor (9/10) of the mammary gland, as the latter did not match any previously described histological subtype. Immunohistochemistry (IHC) was performed for pancytokeratin, cytokeratins 8 and 18, cytokeratin 14, cytokeratins 5 and 6, vimentin, p63, calponin, alpha-smooth muscle actin, Ki-67, ERBB2, estrogen receptor alpha, and progesterone receptor. In 7 of 10 cases, the biphasic nature was confirmed and, on the basis of the IHC results, they were classified as carcinoma and malignant myoepithelioma (4/10), ductal carcinoma (1/10), and carcinosarcoma (2/10). The other 3 of 10 cases were monophasic based on IHC. In the cases of carcinoma and malignant myoepithelioma, the malignant myoepithelial cells were 100% positive for vimentin (4/4) and variably positive for p63, calponin, and cytokeratins (4/4). These findings show that, although rare, biphasic mammary carcinomas do occur in cats. In dogs and humans, tumors composed of malignant epithelial and myoepithelial cells have a less aggressive behavior than certain simple carcinomas, and therefore, their identification might also be clinically significant in the cat.Older adults' experiences and perspectives have been missing in the quest to develop a unified definition of successful aging. Through an online survey using convenience sampling, respondents (N = 477) were asked to report how important 25 specific attributes of successful aging, originating from published literature that examined successful aging from the perspective of older adults, were to them as they age. Over 90% of respondents reported 11 attributes as important or very important to them as they age, which included "remaining free of chronic diseases" and "feeling good about myself." A factor analysis (N = 462) resulted in four dimensions explaining 57.06% of the variance Adaptation and Coping; Being Healthy; Self-Determination; and Social Relationships and Interactions. The findings revealed older adults' definition of what is important to them as they age is multidimensional, with having access to affordable health care and remaining alert and mentally active as critical elements followed by elements of self-determination, coping, and physical and social health. Future research should replicate the study with diverse populations to continue to refine a definition of successful aging that could influence program development and intervention approaches in health and social services.Objectives Rodent models of optic nerve crush (ONC) have often been used to study degeneration and regeneration of retinal ganglion cells (RGCs) and their axons as well as the underlying molecular mechanisms. However, ONC results from different laboratories exhibit a range of RGC injury with varying degree of axonal damage. We developed instrumented tweezers to measure optic nerve (ON) crush forces in real time and studied the correlation between RGC axon loss and force-impulse, the product of force and duration, applied through the instrumented tweezers in mice.Methods A pair of standard self-closing #N7 tweezers were instrumented with miniature foil strain gauges at optimal locations on both tweezers' arms. The instrumented tweezers were capable of recording the tip closure forces in the form of voltages, which were calibrated through load cells to corresponding tip closure forces over the operating range. Using the instrumented tweezers, the ONs of multiple mice were crushed with varied forces and durations and the axons in the immunostained sections of the crushed ONs were counted.
