The present study includes a total of 40 samples of CMT and 5 samples of apparently healthy canine mammary tissues, which were subjected to histological and immunohistochemical examinations. Hyperimmune serum was generated against recombinant MAM-A (rMAM-A) in rabbits to establish a standardized immunohistochemical protocol for evaluating the expression of MAM-A protein in different histotypes of CMT. The histological study demonstrated a wide array of tumor classifications, predominantly consisting of carcinoma, followed by carcinosarcoma and sarcoma. The immunohistochemical examination demonstrated a pronounced expression of MAM-A in the majority of CMT histotypes. The immunohistochemical expression of MAM-A in CMT indicates its potential as a valuable diagnostic biomarker.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"48 1","pages":"79 - 82"},"PeriodicalIF":1.2,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143423500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fabricated through Friction Stir Processing (FSP), the composite benefited from refined microstructure and enhanced properties. The incorporation of Ni-Fe-Ti-Hf-Nb HEA altered the microstructure of the A356 composite, fostering unique phase formation, grain refinement, and improved homogeneity.

Moreover, the addition of Ni-Fe-Ti-Hf-Nb HEA bolstered the wear resistance of the A356 composite.

The infestation by the pea leaf miner (PLM) is characterized by distinctive linear mines, often assessed by counting the number of infested leaves or visually approximating the infested leaf area. However, conventional estimation methods frequently suffer from inaccuracies. To counter this limitation, digital images of infested leaves were processed using ‘ImageJ’ software to precisely map both the total and infested leaf areas. This methodology was employed to evaluate the susceptibility of twenty different field pea (<i>Pisum sativum</i> L.) genotypes to PLM. The analysis revealed that foliage damage was highest in DPFPD 62 (10.2%) and lowest in Pant P 72 (0.55%). Additionally, three out of the twenty genotypes were categorized as ‘highly resistant’. Results indicated a negative correlation of foliage damage by PLM with leaf thickness (<i>p</i> = 0.008) and SPAD chlorophyll meter readings (<i>p</i> = 0.068). While a significant positive correlation was observed between foliage damage and leaf size/area (<i>p</i> = 0.002). Consequently, the precise estimation of PLM infestation through image analysis could offer a promising approach to gain in-depth insights into characterizing infestation severity in relation to host plant traits.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"48 1","pages":"7 - 11"},"PeriodicalIF":1.2,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143423081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
