Findings of present investigation contribute to knowledge of curcumin mediated chemosensitization and its mechanism. Cell adhesion molecule 4 (CADM4) is downregulated in many human cancers. However, CADM4 expression levels in human non-small cell lung cancer (NSCLC) tissues and its roles in NSCLC progression remain unknown. Our study aims to address these issues. We examined CADM4 levels in NSCLC tissues using real-time PCR and western blot. A549 and NCI-H1299 cells were then transfected with pcDNA3.1-CADM4 plasmid or siCADM4 to overexpress or knock down CADM4. Cell proliferation, cell cycle distribution, migration, and invasion were evaluated. NSCLC cells transfected with pcDNA3.1-CADM4 plasmid or siCADM4 were treated with SC79 or LY294002, respectively, to investigate the involvement of the Akt signaling pathway. Male nude mice were subcutaneously injected with stably transfected cells (1 × 106 cells/mice) to observe tumor growth. Stable transfectants were injected into nude mice (1 × 106 cells/mice) via tail vein to observe tumor metastasis. The results showed that CADM4 gene and protein levels in NSCLC tissues were signarget for NSCLC. Single-molecule localisation microscopy (SMLM) gives access to biological information below the diffraction limit, allowing nanoscale cellular structures to be probed. The data output is unlike that of conventional microscopy images, instead consisting of an array of molecular coordinates. These represent a spatial point pattern that attempts to approximate, as closely as possible, the underlying positions of the molecules of interest. Here, we review the analysis methods that can be used to extract biological insight from SMLM data, in particular for the application of quantifying nanoscale molecular clustering. We review how some of the common artefacts inherent in SMLM can corrupt the acquired data, and therefore, how the output of SMLM cluster analysis should be interpreted. Functional comparisons of cortical bone strength properties between hominoid hallucal and pollical metapodials (Mt1 and Mc1, respectively) are lacking. Determining which of these two elements is stronger, and by how much, could be informative because the hallux and pollex are used differently both within and among extant hominoids during locomotion and manipulation (i.e., functional differentiation between autopod pairs). Here, we compare Mt1 and Mc1 midshaft cortical area, polar section modulus, and polar second moment of area, calculated from high-resolution computed tomography images in humans (n = 21), chimpanzees (n = 47), gorillas (n = 24), orangutans (n = 20), siamangs (n = 8), and gibbons (n = 21). Intraindividual comparisons between bones within species were made using paired t-tests. Log10-transformed Mt1Mc1 ratios were created to assess relative strength asymmetry between bones, and interspecific comparisons of these proportions were made using analyses of variance. Absolute strength differences between the Mt1 and Mc1 for all variables were significantly larger in the Mt1 for all species (p  less then  0.05). Significant differences across species in Mt1Mc1 proportions were also found, thereby demonstrating that strength asymmetry between bones differs among taxa (p  less then  0.05); asymmetry was lowest in orangutans, intermediate in gorillas, and greatest in humans, chimpanzees, siamangs, and gibbons. These findings support the hypothesis that the Mt1 is better adapted structurally than the Mc1 for bearing mechanical loads during weight support of locomotion in all extant hominoids and that pedal hallucal grasping likely engenders higher loads than manual pollical grasping in nonhuman hominoids. Thus, functional differentiation in autopod use within and among hominoids is reflected in hallucal and pollical metapodial strength properties. Autism symptomology has a profound impact on cognitive and affective functioning, yet we know relatively little about how it shapes patterns of ongoing thought. In an exploratory study in a large population of neurotypical individuals, we used experience sampling to characterise the relationship between ongoing cognition and self-reported autistic traits. We found that with increasing autistic symptom score, cognition was characterised by thinking more in words than images. Analysis of structural neuroimaging data found that autistic traits linked to social interaction were associated with greater cortical thickness in a region of lingual gyrus (LG) within the occipital cortex. Analysis of resting state functional neuroimaging data found autistic traits were associated with stronger connectivity between the LG and a region of motor cortex. Importantly, the strength of connectivity between the LG and motor cortex moderated the link between autistic symptoms and thinking in words individuals showing higher connectivity showed a stronger association between autistic traits and thinking in words. Together we provide behavioural and neural evidence linking autistic traits to the tendency to think in words which may be rooted in underlying cortical organisation. These observations lay the groundwork for research into the form and content of self-generated thoughts in individuals with the established diagnosis of autism. click here AIMS & BACKGROUND The COVID-19 outbreak spread in China and is a threat to the world. The aims of this study to help health workers better understand the epidemic of the COVID-19 and provide different control strategies toward Hubei Province and other regions in China. METHODS A comprehensive search of the Chinese Center for Disease Control and Prevention official websites and announcements was performed between 20 Jan 2019 and 29 Feb 2020. The relevant data of the distribution of the infection on each reported day were obtained. RESULTS& FINDINGS Up to 29 Feb 2020, 79,824 confirmed cases with the COVID-19 including 66,907 in Hubei Province and 12,377 in other administrative regions were reported. The SARS-COV-2 showed faster epidemic trends compared with the 2003-SARS-CoV. A total of 2,870 deaths have been reported nationwide among 79,824 confirmed cases, with a mortality of 3.6%. The mortality of the COVID-19 was significantly higher in Hubei Province than that in other regions(4.1% versus 0.84%). Since 1 Feb 2020 the number of discharged cases exceeded the number of the dead. By 29 Feb 2020, the number of discharged patients was 41,625, which exceeded the number of hospitalized patients, and the trend has further increased. CONCLUSIONS The infection of the SARS-COV-2 is spreading and increasing nationwide, and Hubei Province is the main epidemic area, with higher mortality. The outbreak is now under initial control especially in other regions outside of Hubei Province. Due to the different epidemic characteristics between Hubei Province and other regions, we should focus on different prevention and control strategies. AIM OF THE STUDY The current study aimed to evaluate the efficacy of different DAAs regimens in the treatment of chronic hepatitis C (CHC) Egyptian patients who failed to achieve SVR after their treatment with SOF-based regimens. METHODS This was a retrospective observational multicenter study that included CHC patients that failed to achieve cure on SOF-based regimens who were re-treated using different DAAs regimen and were allocated according to national guidelines for the treatment of hepatitis C. Primary outcome was to assess the SVR12 rate among prior non-responders after retreatment with a second course of DAAs. RESULTS Our study included 172 patients who failed to achieve SVR after treatment with SOF-based treatment regimen [ age 51.2 ± 11.3, 58.7% men]. Included patients were retreated using SOF/DCV/RBV, SOF/ r/PAR /OMB /RBV, SOF/DCV/SIM, SOF/LDV ± RBV or SIM/SOF. SVR12 was successfully attained in 95.35% (164/172) of the included non-responders. CONCLUSION The current multicenter study proved the efficacy of various DAAs regimens issued by the National Committee for Control of Viral Hepatitis for retreatment of relapsed CHC Egyptian patients. BACKGROUND Pre-eclampsia is a major contributor to pregnancy-associated morbidity and mortality and the management of this complex syndrome needs to be improved. Recently serum collectrin has emerged as a new member of the renin-angiotensin system that regulates the blood pressure through nitric oxide -endothelial nitric oxide synthase pathway. OBJECTIVE To evaluate the correlation of serum collectrin level and preeclampsia onset. STUDY DESIGN A prospective case control study. PATIENTS AND METHODS Ninety pregnant women attended the outpatient clinic Al-Yarmook Teaching Hospital in Baghdad / Iraq along the period from April 2018 until December 2018 had been divided into three groups. Group A included 30 pregnant women presented with early onset pre-eclampsia (before 34 weeks of gestation), group B included 30 pregnant women presented with late onset pre-eclampsia (at or after 34 weeks of gestation) and group C included 30 apparently healthy term pregnant women. Serum collectrin levels were measured for each pregnant woman by using enzyme-linked immunosorbent assay analyzer. RESULTS The mean serum collectrin was the lowest in pregnant women with early onset pre-eclampsia (61.65 ± 3.62 pg/ml) while it was (82.61 ± 6.41 pg/ml) for pregnant women with late onset pre-eclampsia and (101.11 ± 8.27 pg/ml) for healthy term pregnant women. These differences were found to be significant (p value = 0.001). This significant decrement was inversely correlated with the systolic blood pressure (r = -0.565, p-value = 0.001) and diastolic blood pressure and (r = -0.748, p-value = 0.001). CONCLUSION Serum collectrin levels had a significant role in controlling the blood pressure in pregnant women with a significant inverse correlation between serum collectrin concentrations and blood pressure. OBJECTIVE This study aims to evaluate the accuracy of frozen section (FS) in mucinous borderline ovarian tumors (BOTs) and to examine the factors associated with misdiagnosis. METHODS In this retrospective study, cases diagnosed as mucinous BOTs by FS or final pathologic (FP) results were studied. The results of FS and FP were compared, and the factors associated with misdiagnosis were analyzed. RESULTS Seventy-nine cases were examined. The median tumor diameter was 16 (6-50) cm, and 89.9 % of cases had tumors ≥10 cm. The overall agreement ratio between FS and FP was 79.7 %. Over-diagnosis and under-diagnosis rates were 3.8 % and 16.5 %, respectively. The sensitivity and positive predictive values were both 88.7 %. None of the underdiagnosed patients (13 cases) had recurrence during the 100-month median follow-up (9-222). Misdiagnosis was more common in tumors less then 10 cm (p = 0.025). The under-diagnosis rate for tumors less then 10 cm was 30.8 %. Tumor size less then 10 cm was significantly associated with misdiagnosis in univariate and multivariate analyses (Odds ratio OR 4.92, 95 % Confidence Interval CI (1.08-22.45) p = 0.040; OR 5.17, 95 % CI (1.07-25.05) p = 0.041, respectively). Laterality and preoperative CA 125 levels were not associated with misdiagnosis. CONCLUSION Tumor size less then 10 cm is associated with misdiagnosis in mucinous BOTs. Laterality and CA 125 levels do not affect diagnostic accuracy. The evaluation of FS by gynecologic pathologists can help to increase the accuracy of FS.
