The abnormal excess of mitotic figures is commonly seen in oral epithelial dysplasia (ED) and oral squamous cell carcinoma (OSCC). In present study, we compared the number of mitotic figures in normal oral mucosa, epithelial dysplasia & OSCC sections with haematoxyline & eosine (H&E) and 1%Crystal Violet & Nuclear Fast Red (CV&NFR) stain, also the efficacy of the CV&NFR stain as compared to H & E stain. We investigated the correlation between the number of mitotic figures & grades of OSCC. Study sample comprised of two serial sections of archival blocks of normal oral mucosa & diagnosed cases of epithelial dysplasia & OSCC. One slide stained with H& E & the other one with 1% CV & NFR. Mitotic figures were counted with the grid eyepiece. There was significant increase in number of MFs in oral ED and OSCC in comparison with normal oral mucosa. There was a highly significant increase in number of MFs in CV&NFR stained tissue sections when compared with H & E stain. Metaphase is the most commonly observed phase of mitosis. In summary, our study proposes the use of Crystal violet & Nuclear fast red stain as a selective stain for better contrast & easy identification MFs.","PeriodicalId":45335,"journal":{"name":"Journal of Experimental Therapeutics and Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34967798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Group 1 (n=211) determined as the patients whose diameter size of the removed fibroids ≤ 5 cm and group 2 (n=146) determined as patients with > 5 cm diameter size.

However, the effect of PM on IL-2 induced activation of T lymphocytes, which play a major role in antitumor immunity has not been studied. The objective of the present study was to evaluate the effect of PM on IL-2 induced proliferation of T cells, generation of lymphokine activated killer cells (LAK cells) and the signaling pathways involved in activation of T cells by IL-2. PM inhibited the IL-2 induced proliferation of mouse splenic T cells and the generation LAK cells at very low concentrations. The suppression of T cell proliferation by PM was associated with the inhibition of IL-2 induced Janus kinase/signal transducers and activators of transcription (Jak/STAT) and extracellular signal-regulated kinase 1 and 2 (Erk1/2) signaling pathways. PM also inhibited the proliferation and differentiation-related immediate early gene products such as p-c-fos, p-c-jun, c-myc and cyclin D1. In addition, antiapoptotic (prosurvival) NF-кB, p-Akt and p-mTOR were also inhibited by PM. These data demonstrated that PM inhibits IL-2 induced T cell activation and generation of LAK cells by disrupting multiple cell signaling pathways induced by IL-2.","PeriodicalId":45335,"journal":{"name":"Journal of Experimental Therapeutics and Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34967799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their incidence during pregnancy is approximately 2 percent and they are associated with some complications such as preterm labor, placental abruption, fetal malpresentation, obstructed labor, cesarean delivery, and postpartum hemorrhage. They may develop anywhere within the muscular wall of the uterus, including submucosal, intramural, or subserosal areas. Some of the submucous myomas may be pedunculated and eventually may protrude through the cervical canal to the vagina. They later become necrotic and sometimes infected. Vaginal myomectomy is recommended as the initial treatment of choice for a prolapsed, pedunculated myoma except when other indications require an abdominal procedure. Inversion is a condition in which the uterus turns inside out with prolapse of the fundus through the cervix. It is seen in acute and chronic forms. Chronic inversion may follow an incomplete obstetric inversion unnoticed or left uncared. Herein, we present, a case of infected non-puerperal uterine inversion due to submucous leiomyoma that was originating from fundus and the diagnostic dilemma it presents in the after puerperal stage.","PeriodicalId":45335,"journal":{"name":"Journal of Experimental Therapeutics and Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34966189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eight patients with lung cancer were recruited, 3 small cell lung cancer, 3 non-small cell lung cancer, 1 adenocarcinoma and 1 squamous cell carcinoma. A median value of extracted RNA and DNA amounts from specimen was 1573 ng (range 367.5 to 8900) and 6700 ng (range 550 to 68000 ng), respectively. We applied amplicon sequencing panels that cover exon regions of 41 genes related to lung tumorigenesis as well as total 61 major variants of ALK, ROS, RET or NTRK1 fusion transcripts. Nineteen of 41 gene mutations were detected in our isolated DNAs of 8 patients. We could detect four to eleven mutations in each specimen; however the mutation combination in each 8 patients were different. The most common genetic alterations were TP53, KMT2D, MET, NOTCH2 and SETD2, which were detected in 4 to 6 patients. We did not detect fusion transcripts of ALK, ROS, RET and NTRK1 in every specimen. In conclusion, multiplex genomic test was performed on small amounts specimen of bronchoscopy biopsy with a 100% success rate.

Diagnosis can be difficult because of this condition's rarity, and other similar appearing mesenchymal lesions should be ruled out.Methods: A 50-year-old postmenopausal woman came to our hospital because of abdominopelvic pain. Ultrasonography revealed a 41x33 mm heterogeneous solid mass in the right ovary. Total blood counts, biochemical parameters, and tumor markers were within normal ranges. Total abdominal hysterectomy, and bilateral salpingo oophorectomy were performed. Examination of a frozen, specimen revealed fibroma; however, the final histopathological diagnosis was low grade fibrosarcoma of the ovary. Microscopic examination demonstrated densely cellular, spindle-shaped tumor cells with increased mitotic activity (5 to 6 mitoses per 10 high-power fields).Results: Immunohistochemical analysis revealed that the tumor cells were positive for vimentin and negative for actin and desmin and that the Ki 67 proliferation index was 30% to 40%. The patient did not receive adjuvant treatment, and remained free of disease after a follow up of 6 months.Conclusions: Although ovarian fibrosarcomas are unusual causes of solid masses in postmenopausal women, they should be considered when adnexal masses are examined in these patients. Mitotic activity and Ki-67 positivity were identified as important diagnostic factors for ovarian fibrosarcoma.","PeriodicalId":45335,"journal":{"name":"Journal of Experimental Therapeutics and Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34966190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
