Analysis based on the data mining of Oncomine revealed that the ADAMTSL3 and PTEN genes were expressed at lower levels in HCC cells than they were in normal liver cells, indicating their tumour-suppressive roles. Downregulation of ADAMTSL3 and PTEN displayed poor overall survival (OS) and predicted poor relapse-free survival (RFS), further supporting their tumour-suppressive roles. Moreover, knocking out either the ADAMTSL3 or PTEN genes promoted either the proliferation or metastasis of HCC cells, respectively. CONCLUSIONS Using both in vitro and in vivo approaches, we described the profound role of the ADAMTSL3 and PTEN genes. This study indicates novel candidate targets for use in HCC treatment and therapy.PURPOSE To evaluate the difference in oncologic outcome between vulvar cancer patients with uni- and bilateral inguino-femoral lymph nodal involvement and to identify factors affecting their oncologic outcome MATERIALS AND METHODS Patients who underwent inguino-femoral lymphadenectomy for vulvar cancer were classified into three groups according to their lymph nodal status at the histology analysis (negative, positive one side, positive bilaterally). PFS and OS survival were calculated using the Kaplan-Meier method. Univariate and multivariate analyses were performed to analyze factors predicting overall survival and progression-free survival. Multivariable models were used for variables reporting a p value ≤ 0.1 at the univariate analysis. p values ≤ 0.05 were considered statistically significant. RESULTS One hundred and forty-six patients were considered for the analysis. Patients with bilaterally negative lymph nodes had significantly longer PFS and OS as compared to patients with unilateral and bilateral involvement. Patients with unilateral lymph nodal involvement had better PFS than patients with bilateral lymph nodal involvement. Among these patients, the difference in the OS approached but did not reach statistical significance. At the multivariate analysis, the tumor size affected PFS and lymph nodal involvement affected OS. CONCLUSION Vulvar cancer patients with bilateral positive lymph nodes have worse oncologic outcome as compared to patients with unilateral lymph nodal involvement; similarly, patients with unilateral lymph nodal involvement have worse oncological outcome as compared to patients with bilateral negative lymph nodes. Furthermore, tumor size and lymph nodal status are independent factors predicting recurrence rate and overall survival, respectively.The hairy rove beetle, Creophilus maxillosus (Linnaeus) (Staphylinidae), is recognized for its use in forensic entomology. However, insufficient developmental data exist for the Central European population of this species. Accordingly, we studied the development of C. maxillosus at ten constant temperatures (10-32.5 °C). Based on these results, linear and nonlinear developmental models were created and validated. We also studied the effect of different homogenous diets (third-instar larvae or puparia of Calliphora sp. Robineau-Desvoidy or Lucilia sp. Robineau-Desvoidy (Diptera Calliphoridae) or mix of first- and second-instar larvae of Necrodes littoralis (Linnaeus) (Coleoptera Silphidae)) on the development and mortality of C. maxillosus. Average total development times ranged between 122.21 days at 15 °C and 22.18 days at 30 °C. Beetles reached the adult stage in seven out of ten temperatures (15-30 °C). No beetles reached the adult stage when fed with larvae of N. littoralis; their development times at first and second larval stage were also significantly longer than in other food conditions. When C. maxillosus larvae were fed with blowfly larvae, the highest mortality was observed at the pupal stage, as compared when they were fed with blowfly puparia-at the first larval stage. While validating thermal summation models, the highest age estimation errors were found for beetles bred at 10 and 12.5 °C (between 21 and 43% for all developmental events). Age estimation errors were on average higher for pupation and eclosion than hatching and first and second ecdyses. While validating the models with specimens fed with different diets, the highest errors were recorded for beetles fed with N. littoralis larvae (22% for the first ecdysis and 33% for the second ecdysis) and Lucilia sp. puparia (32% for pupation and 22% for eclosion). Implications for C. maxillosus use in forensic entomology are discussed.Identification of semen and then spermatozoa is essential to verify that sexual activity has occurred in alleged cases of sexual assault. Microscopic examination commonly used for spermatozoa identification is however time-consuming and can often lead to false-negative results for samples with deformed and, or, limited number of spermatozoa. Bersacapavir modulator To address this limitation, we report on a novel 3-plex MSRE-PCR (methylation-sensitive restriction enzyme-PCR) assay to specifically identify spermatozoa. This assay is comprised of 3 markers a digestive control marker (DC), sperm-specific marker (SP), and Y chromosome marker (SRY). A total of 214 samples from 10 body fluids or tissues were analyzed. Specificity testing showed that all the normal semen samples were unambiguously identified as being sperm-positive, and no other body fluid (or tissues) showed a sperm-specific signal in the electropherogram. Testing for sensitivity showed that 0.1 ng of DNA from a semen extract was sufficient to identify the presence of spermatozoa by this assay. Mixture analyses illustrated the sensitivity of the assay when the vaginal/semen DNA ratio (80/0.1) was under 800 or the menstrual blood/semen DNA ratio (5/0.1) was under 50, the trace amounts (approximately 0.1 ng) of DNA from semen can still be identified by this 3-plex MSRE-PCR assay. This assay was also applied to the identification of 31 non-probative forensic samples from 18 sexual assault cases. The case studies showed that the 3-plex MSRE-PCR assay was an improvement in the sensitivity of spermatozoa detection.Factors that are most associated with positive lymph node status in melanoma are Breslow thickness and ulceration. However, there are other factors that have been little explored and could help in the identification of "at risk patients" harbouring occult metastasis. The objective of this study was to determine whether intensity of tumour-infiltrating lymphocytes (TILs) in a cohort study (N = 4133) is an independent predictor of sentinel lymph node (SLN) status in patients with primary cutaneous melanoma. Of the patients with cutaneous melanoma who resulted negative for nodal metastasis, 50.7% had moderate/marked TILs versus 27.7% among those patients who resulted positive for nodal metastasis. In the multivariate analysis, controlling for sex, age, mitotic rate, ulceration and Breslow, high levels of TILs in primary invasive melanoma was associated with a lower risk of developing SLN metastasis (OR 0.46; 95% CI 0.23-0.95, p = 0.037). When the analysis was stratified by sex, the protective effect of moderate/marked TIL remained only for women (OR 0.
