Characterization of primary pulmonary adenosquamous carcinoma‐associated pleural effusion          下载免费PDF全文

Jennifer Stewart  Andrew Holloway  Roberta Rasotto  Kelly Bowlt 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》2016,45(1):179-183

A 10‐year‐old, female spayed Shih Tzu was presented due to weight loss, increased respiratory effort and lethargy, determined to be secondary to a congenital para‐esophageal diaphragmatic defect with partial herniation of the stomach and spleen. Four days following reduction surgery of the displaced abdominal organs thoracic effusion developed. Thoracic fluid evaluation revealed a cell‐rich, protein‐poor modified transudate with neutrophils, reactive mesothelial cells, and atypical epitheloid cells which occasionally appeared to be keratinizing, consistent with neoplastic exfoliation. Thoracic effusion recurred 2 days later, with similar characteristics as the initial sample. Computed tomography (CT) indicated consolidation and displacement of the right middle and accessory lung lobes. Exploratory thoracic surgery demonstrated a thickened, hyperemic right middle lung lobe, and thickened pericardial diaphragmatic ligament. Histologic evaluation of these tissues identified a primary pulmonary adenosquamous carcinoma with intravascular and pleural invasion. Based on these cytologic, histologic, and clinical findings, we conclude that primary pulmonary carcinomas may involve superficial thoracic structures and exfoliate into a thoracic effusion.  相似文献   

Preliminary Study on the Activity of Phycobiliproteins against Botrytis cinerea     

Hillary Righini  Ornella Francioso  Michele Di Foggia  Antera Martel Quintana  Roberta Roberti 《Marine drugs》2020,18(12)

Phycobiliproteins (PBPs) are proteins of cyanobacteria and some algae such as rhodophytes. They have antimicrobial, antiviral, antitumor, antioxidative, and anti-inflammatory activity at the human level, but there is a lack of knowledge on their antifungal activity against plant pathogens. We studied the activity of PBPs extracted from Arthrospira platensis and Hydropuntia cornea against Botrytis cinerea, one of the most important worldwide plant-pathogenic fungi. PBPs were characterized by using FT-IR and FT-Raman in order to investigate their structures. Their spectra differed in the relative composition in the amide bands, which were particularly strong in A. platensis. PBP activity was tested on tomato fruits against gray mold disease, fungal growth, and spore germination at different concentrations (0.3, 0.6, 1.2, 2.4, and 4.8 mg/mL). Both PBPs reduced fruit gray mold disease. A linear dose–response relationship was observed for both PBPs against disease incidence and H. cornea against disease severity. Pathogen mycelial growth and spore germination were reduced significantly by both PBPs. In conclusion, PBPs have the potential for being also considered as natural compounds for the control of fungal plant pathogens in sustainable agriculture.  相似文献   

Genetic manipulation for enhancing calcium content in potato tuber     

Park S  Kang TS  Kim CK  Han JS  Kim S  Smith RH  Pike LM  Hirschi KD 《Journal of agricultural and food chemistry》2005,53(14):5598-5603

Increased calcium (Ca) in potatoes may increase the production rate by enhancing tuber quality and storability. Additionally, increased Ca levels in important agricultural crops may help ameliorate the incidence of osteoporosis. However, the capacity to alter Ca levels in potato tubers through genetic manipulations has not been previously addressed. Here we demonstrate that potato tubers expressing the Arabidopsis H+/Ca2+ transporter sCAX1 (N-terminal autoinhibitory domain truncated version of CAtion eXchanger 1) contain up to 3-fold more Ca than wild-type tubers. The increased Ca appears to be distributed throughout the tuber. The sCAX1-expressing potatoes have normally undergone the tuber/plant/tuber cycle for three generations; the trait appeared stable through successive generations. The expression of sCAX1 does not appear to alter potato growth and development. Furthermore, increased Ca levels in sCAX1-expressing tubers do not appear to alter tuber morphology or yield. Given the preponderance of potato consumption worldwide, these transgenic plants may be a means of marginally increasing Ca intake levels in the population. To our knowledge, this study represents the first attempts to use biotechnology to increase the Ca content of potatoes.  相似文献

Protective Effect of <Emphasis Type="Italic">Juglans regia</Emphasis> L. Walnut Extract Against Oxidative DNA Damage     

Cinzia Calcabrini  Roberta De Bellis  Umberto Mancini  Luigi Cucchiarini  Vilberto Stocchi  Lucia Potenza 《Plant foods for human nutrition (Dordrecht, Netherlands)》2017,72(2):192-197

Walnuts (Juglans regia L.) are relevant components of the Mediterranean diet providing important macronutrients, micronutrients and other bioactive constituents including unsaturated fatty acids, proteins, fiber, vitamins, minerals, phytosterols and polyphenols. Although the walnut beneficial effects in human health are widely recognized by a lot of epidemiologic studies very little is known regarding its effect on damaged DNA. The aim of the present study was to investigate the effect of Juglans regia L. ethanolic extract from kernel on the induction of DNA strand breaks by thiol/Fe³⁺/O₂ mixed function oxidase, tert-butyl hydroperoxide or UVC radiations in acellular and cellular models. Plasmid DNA cleavage and fast Halo assay were used to monitor oxidative damage to DNA. Both approaches showed protection of oxidatively injured DNA. These results agree with a lot of scientific proofs which recommend walnut as dietary adjunct in health promotion and prevention as well as in treatment of lifestyle-related oxidative diseases.  相似文献   

Erythema multiforme in a spotted hyena (Crocuta crocuta).     

Christopher S Hanley  Heather A Simmons  Roberta S Wallace  Victoria L Clyde 《Journal of zoo and wildlife medicine》2005,36(3):515-519

A 10.5-yr-old male spotted hyena (Crocuta crocuta) developed acute, severe erythematous and ulcerative dermatitis of the hindquarters, feet, face, and ears 19 days after receiving a recombinant canary pox vectored canine distemper vaccine. Biopsies of the lesions supported a diagnosis of erythema multiforme (EM), which is an immune-mediated disorder that can occur days to months after exposure to antigenic stimuli. During the lengthy recovery, esophageal regurgitation and ulceration developed either as complications of the disease or secondary to therapy. The esophageal disease was managed with metoclopramide, sulcrafate, omeprazole, and frequent feedings. The distemper vaccine is postulated to have been the inciting cause of EM in this animal.  相似文献
