In this study, 20 CMT tissue paraffin blocks preserved in the laboratory were used. Slides were prepared for histopathological examination and immunohistochemistry. Hyperimmune serum raised against the canine recombinant MMP-11 (rMMP-11) in mice was used to standardize immunohistochemistry to assess expression of MMP-11 protein in various histotypes of CMT. Based on the histopathological examination of hematoxylin and eosin (H&E)-stained tissue sections, the CMT tissues were classified into complex carcinoma, mixed mammary tumor, papillary carcinoma and anaplastic carcinoma. A strong MMP-11 expression was observed in 75% of the histotypes of CMT under study. The findings suggest that MMP-11 could act as molecular marker for the immunohistochemistry-based diagnosis of mammary tumors in dogs.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"47 4","pages":"433 - 436"},"PeriodicalIF":1.2,"publicationDate":"2024-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140017769","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}

Efavirenz has been classified as a class D drug which means that there have been reports of reproductive toxicity induced by it and should be used only when potential benefits outweigh the risk. Pregnant Swiss albino mice were divided into the following groups: control group (C): mice treated with distilled water (6 mice) and treated group (T): mice treated with EFV (50 mg/kg) (6 mice). All the mice were given the drug and distilled water from gestation days 6–15 by oral route. On the 18th day of gestation, each group’s mice blood was collected from retro-orbital sinus for biochemical assay, and then, they were killed by cervical dislocation. Laparotomy was done to resect out the fetuses which were weighed, and then fixed in 10% formalin. Their liver was processed for histological study under H&E and PAS stain. The microscopic study of the liver showed the reduced density of hepatoblasts and progenitor cells, deficient sinusoid formation and destruction of the central vein in the treated group as compared to the control. A significant reduction in the weight of the fetal liver was observed. The values of SGOT, SGPT and serum bilirubin were found to increase in the treated group, whereas the values of serum albumin and total protein were found to decrease.

Designing a distributed and reliable access control and user authentication scheme for IoMT involves multiple layers of security measures to ensure the integrity, confidentiality, as well as availability of sensitive patient data. However, the major problem with smart healthcare systems is data security and privacy. Blockchain can resolve these issues due to its immutability and transparency features. Most of the existing research enhances security and data privacy but they do not consider the overhead, delay, and scalability. The clustering-based proposed approach adopted the real-world issues of blockchain, i.e., delay, and scalability. It is an efficient access control approach that enables users to establish their desired access control policy to protect their private medical data. It uses a dual chain mechanism in which the access policies are stored in one chain, while the data transactions are stored in another chain. This approach addresses the challenge of access control resolution by enabling data owners to decide their desirable access policies. The experimental results show the efficiency of the proposed scheme in terms of processing time, computational time and its resilience against various security threats.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"47 5","pages":"529 - 537"},"PeriodicalIF":1.2,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139924875","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}

This WL is detrimental to the part produced by decreasing the fatigue life. Also, the surface integrity is deteriorated due to dynamic phase transformations. So, an attempt was made with super hardened AISI D4 steel turned with cubic boron nitride insert under Dry Machining, also gas mixture cooling.
