The skin mucus in lower vertebrates such as fish with strong innate immune system has many unique and valuable bioactive compounds that can be used for inducing apoptosis in cancer cells. This study was looking for the cytotoxic potential of mucus from the two fish species, including round goby (Neogobius melanostomus) and common carp (Cyprinus carpio), and inducing apoptosis in MCF7 and LNCaP cancer cell lines via influencing P53 gene expression and cell cycle arrest. Results showed that the both mucus types have cytotoxic effects on the both cancer cell lines whereas they have no severe effect on normal primary fibroblast cells. In addition, round goby mucus and common carp mucus selectively induced apoptosis in the LNCaP and MCF7 cells, respectively, through up-regulating P53 gene and arresting cell cycle at the G1 phase. Taken together, this study suggested that the both mucus types can selectively influence P53 pathway and induce apoptosis in especial cancer cells. The skin mucus derived from round Goby and common Carp can be a promising candidate for investigation about apoptosis and molecular targeting therapy in cancer.Mexican American adolescents have an increased risk for obesity compared to non-Hispanic whites (NHWs), especially as their degree of acculturation increases. Snack intakes can impact diet quality and may affect obesity risk, yet little is known about differences in snack intakes among NHW and Mexican American adolescents from different acculturation groups. This study compared diet quality and snack intakes among NHW and Mexican American adolescents from different acculturation groups. This study used cross-sectional data from 3636 Mexican American and NHW adolescents in the 2005-2014 National Health and Nutrition Examination Survey. Acculturation was defined based on generational status and language use. Outcomes were Healthy Eating Index-2015 (HEI-2015) score, daily energy intake from snacks, snack frequency, energy value of snacks, and percent contribution of snacks to total daily energy. Analysis of covariance was used to compare outcomes across groups, after adjustment for sex and income. In the full sample, mean HEI-2015 score was 45 ± 0.4. Non-Hispanic white adolescents had modestly poorer diet quality compared to US-born adolescents with a foreign-born parent and Mexican-born adolescents (P  less then  0.001). Mean daily snack intake was 583 ± 16 kcal. Items in the Snacks and Sweets and Beverages categories contributed more than half of the energy provided by snacks. Non-Hispanic white adolescents had a greater total snack intake compared to all language use at home groups, except equal Spanish and English use. Improving the types of foods consumed as snacks has the potential to partially mitigate differences in snack intakes and diet quality among non-Hispanic white and Mexican American adolescents.Neuroendocrine neoplasms comprise a heterogeneous group of tumors, categorized into neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs) depending on tumor differentiation. NECs and high-grade NETs (G3) confer a poor prognosis, demanding novel treatment strategies such as immune checkpoint inhibition in tumors with microsatellite instability (MSI). To study any possible intratumoral heterogeneity of MSI, a tissue microarray (TMA) containing 199 NETs and 40 NECs was constructed to screen for MSI using immunohistochemistry (IHC) for the mismatch repair (MMR) proteins MLH1, PMS2, MSH2, and MSH6. Four cases suspicious for MSI were identified. Validation of MSI by repeated IHC on large sections and polymerase chain reaction (PCR)-based analysis using the "Bethesda Panel" confirmed MSI in 3 cecal NECs. One pancreatic NET G3 with MSI-compatible TMA results was MMR intact on large section IHC and microsatellite stable (MSS). The remaining 235 tumors exhibited intact MMR. Protein loss of MLH1/PMS2 was found in two and MSH6 loss in one cancer with MSI. Deucravacitinib Large section IHC on all available tumor-containing tissue blocks in NECs with MSI did not identify aberrant tumor areas with intact MMR. Our data indicate that MSI is common in colorectal NECs (3 out of 10) but highly infrequent in neuroendocrine neoplasms from many other sites. The lack of intratumoral heterogeneity of MMR deficiency suggests early development of MSI during tumorigenesis in a subset of colorectal NECs and indicates that microsatellite status obtained from small biopsies may be representative for the entire cancer mass.PURPOSE Structured light scanning is a promising inexpensive and accurate intraoperative imaging modality. Integration of these scanners in surgical workflows has the potential to enable rapid registration and augment preoperative imaging, in a practical and timely manner in the operating theatre. Previously, we have demonstrated the intraoperative feasibility of such scanners to capture anatomical surface information with high accuracy. The purpose of this study was to investigate the feasibility of automatically characterizing anatomical tissues from textural and spatial information captured by such scanners using machine learning. Assisted or automatic identification of relevant components of a captured scan is essential for effective integration of the technology in surgical workflow. METHODS During a clinical study, 3D surface scans for seven total knee arthroplasty patients were collected, and textural and spatial features for cartilage, bone, and ligament tissue were collected and annotated. These feattiple types of anatomical tissue. The ability to automatically characterize tissues in intraoperatively collected surface models would streamline the surgical workflow of using structured light scanners-paving the way to applications such as 3D documentation of surgery in addition to rapid registration and augmentation of preoperative imaging.The recent development of multiband functional magnetic resonance imaging (MB-fMRI) allows for the reduction of sampling period by simultaneously exciting multiple slices-the number of which is referred to as the multiband factor. Simultaneously recorded electroencephalography (EEG)/MB-fMRI has yet to be validated for data quality against conventional single band (SB)-fMRI. Pilot scans were conducted on phantoms twice and on a healthy volunteer to ensure no heating effects. In the main study, two thermometer probes were attached to 16 healthy individuals (ages 20-39, 9 females) whilst they completed two sets of 16-min resting-state and two sets of 9-min n-back task scans-each set consisting of one MB4 and one SB pulse sequence. No heating effects were reported and thermometer data showed mean increases of  less then  1.0 °C. Minimal differences between the two scan types were found in EEG channel variance and spectra. Expected decreases in MB4-fMRI tSNR were observed. In n-back task scans, little to no differences were detected in both EEG source analyses and fMRI local analyses for mixed effects.
