Published: March 2020

Abstract
Background: the emergence of new drugs for cancer treatment has reflected on increasing patient survival. However, these drugs bring side effects, such as dry mouth sensation and hyposalivation. This study aimed to evaluating the relationship between patients with cancer and xerostomia and hyposalivation. Method : cross-sectional study with 114 patients diagnosed with cancer treated with anastrozole and / or bicalutamide. Age, type of neoplasia, gender, xerostomia, and type of medicine were obtained through questionnaire. Resting and stimulated salivary flow were collected by the researcher. After collection, using a 10 mL disposable syringe, salivary flow was quantified in millimeters and divided into 6 (collection period). A Descriptive statistical analysis, Chi-square test and T-test were carried out through Statistical Package for Social Science® (SSPS) version 21, considering p<0.05. Results : results showed that 67 (55.8%) patients who use hormone therapy presented hyposalivation and 73 (64. 0%) patients presented xerostomia. Conclusion : According to the results from this study, there is statistically significant association between stimulated hyposalivation and hormone therapy usage (p = 0.015). Statistically significant association was also observed among hyposalivation and xerostomia and hormone therapy usage (p=0.049 and p = 0.001).

Abstract
Background: One of the health risks posed to astronauts during deep space flights is exposure to high charge, high-energy (HZE) ions (Z>13), which can lead to induction of hepatocellular carcinoma (HCC). However, little is known on the molecular mechanisms of HZE irradiation induced HCC.Results: We performed comparative RNA-Seq transcriptomic analyses to assess the carcinogenic effects of 600 MeV/n 56 Fe (0.2 Gy), 1 GeV/n 16 O (0.2 Gy), and 350 MeV/n 28 Si (0.2 Gy) ions in a mouse model for irradiation-induced HCC. C3H/HeNCrl mice were subjected to total body irradiation to simulate space environment HZE-irradiation, and liver tissues were extracted at five different time points post-irradiation to investigate the time-dependent carcinogenic response at the transcriptomic level. Our data demonstrated a clear difference in the biological effects of these HZE ions, particularly immunological, such as Acute Phase Response Signaling, B Cell Receptor Signaling, IL-8 Signaling, and ROS Production in Macrophages. Also seen in this study were novel unannotated transcripts that were significantly affected by HZE. To investigate the biological functions of these novel transcripts, we used a machine learning technique known as self-organizing maps (SOMs) to characterize the transcriptome expression profiles of 60 samples (45 HZE-irradiated, 15 non-irradiated control) from liver tissues. A handful of localized modules in the maps emerged as groups of co-regulated and co-expressed transcripts. The functional context of these modules was discovered using overrepresentation analysis. We found that these spots typically contained enriched populations of transcripts related to specific immunological molecular processes (e.g., Acute Phase Response Signaling, B Cell Receptor Signaling, IL-3 Signaling), and RNA Transcription/Expression.Conclusions: A large number of transcripts were found differentially expressed post-HZE irradiation. These results provide valuable information for uncovering the differences in molecular mechanisms underlying HZE specific induced HCC carcinogenesis. Additionally, a handful of novel differentially expressed unannotated transcripts were discovered for each HZE ion. Taken together, these findings may provide a better understanding of biological mechanisms underlying risks for HCC after HZE irradiation, and may also have important implications for discovery of potential countermeasures against and identification of biomarkers for HZE-induced HCC.

Abstract
Purpose: To investigate the associations between morphological blastocyst parameters and the sex ratio (male:female) of singleton live births resulting from single-blastocyst frozen embryo transfer (FET) cycles. Methods: This retrospective analysis included 1210 couples who underwent single-blastocyst FET of warmed day 5 or 6 blastocysts and achieved a singleton live birth between January 2015 and February 2019. The sex ratios in the different blastocyst groups were compared using the chi-square test. The associations of morphological blastocyst parameters, including the blastocoel expansion, inner cell mass and trophectoderm grades, with the sex ratios of live births were analyzed using multiple regression models. Results: The included female patients had an average age and body mass index of 30.5±4.5 years and 23.6±3.2 kg/m2, respectively. blastocyst transfers occurred on day 5 in 783 cases (64.7%) and day 6 in 427 cases (35.3%). Among the day 5 FET cycles, 55.4% of resulting infants were male and 44.6% were female, while among the day 6 cycles, 54.6% of infants were male and 45.4% were female ( P =0.074). Blastocysts quality was assessed according to morphological parameters, which was divided into high-quality (AA,AB,BB,BC) and poor-quality(AC,BC). High-quality blastocyst transfer was associated with a significantly higher sex ratio (60%, 383/638) relative to poor-quality transfer (49.7%, 284/572) ( P< 0.001). The sex ratio of births resulting from blastocyst transfer differed significantly with respect to the trophectoderm grade ( P <0.001). After adjusting for confounders, a grade B trophectoderm was significantly associated with a higher sex ratio among singleton live births (odds ratio: 0.591, 95% confidence interval: 0.463–0.756, P <0.001; reference: grade C trophectoderm). In contrast, the characteristics of blastocoel expansion and the score of the inner cell mass were not significantly associated with the sex ratio among singleton live births. Conclusions: The sex ratio among singleton live births is affected by the quality of blastocysts. A grade B trophectoderm is associated with a higher probability that a single-blastocyst FET cycle will result in a male infant.

Abstract
Background: Chinese perch, a carnivorous fish, can accept artificial diet after domestication nowadays, and this farm way will gain high economic interest and sustainability. However, the high content and high quality requirement of dietary protein make it need the high cost in Chinese perch. Therefore, the aim of this study was to explore the effect of fish meal replacement by low- or high-rapeseed meal on growth performance, feeding, lipid and glucose metabolism. Methods: Three experimental diets were formulated with 0, 10% and 30% rapeseed meal, named as control, RSL and RSH, groups respectively. After the 8-week of feeding trial, growth performance, lipid metabolism and AMPK-mTOR-signal pathways were measured. Results: Chinese perch fed with RSH and RSL diets showed significantly decreased WG, SGR, BFR, VSI, MSI and the whole-body crude lipid compared to those fed with the control diet (P < 0.05). Fish in RSL group decreased feed intake, serum LDL-C, hepatic mRNA expression of LPL, PEPCK and phosphorylated Grb10 (P < 0.05). In visceral adipose tissue, mRNA expression of FAS, SREBP1, ACC1, HL, CPT1 and PEPCK were all significantly down-regulated (P < 0.05). Fish in RSH group showed phosphorylated AMPK, hepatic mRNA expression of SREBP1, ACC1, FAS, PPARα and CPT1 were down-regulated, while HSL, G6PD and PC were up-regulated (P < 0.05). In visceral adipose tissue, mRNA expressions of SREBP1, LPL, CPT1 and PEPCK were down-regulated, while mRNA expression of HSL was up-regulated (P < 0.05). Conclusions: Chinese perch fed with RSL and RSH diets showed decreased fat deposition in viscera. Fish fed with low level of rapeseed meal diet ate less diet, which caused inhibited lipid metabolism in the liver and visceral adipose tissues.Fish fed with high level of rapeseed meal diet inhibited hepatic FA synthesis, activated lipolysis, hence reducing Acetyl-CoA pool. In turn, β-oxidation were inhibited, glycolysis was activated, thus lipid accumulation was decreased. In visceral adipose tissue, lipid uptake was inhibited, caused inhibited FA synthesis, β-oxidation, glycerol synthesis, and improved lipolysis.

Abstract
Background We analyzed the feasibility and outcomes of early surgical ligation in very low birth weight infants (VLBWIs) with hemodynamically significant patent ductus arteriosus (HSPDA) and investigated predictors for surgical treatment after unsuccessful medical management. Methods Medical records from the neonatal intensive care unit of Hanyang University Seoul Hospital from January 2010 to December 2018 were retrospectively reviewed. 233 VLBWIs with HSPDA were enrolled in our study. Of these infants, 134 underwent surgical ligation and were subdivided into the early ligation group (n = 49; within 10 days of age) and the late ligation group (n = 85; after 10 days of age). Results The mean gestational age and birth weight were significantly lower in the patent ductus arteriosus (PDA) ligation group than in the Non-ligation group (p < 0.001). PDA ductal diameter > 2.0 mm (p < 0.001), low Apgar score at 5 minutes (p = 0.033), and chorioamnionitis (p = 0.037) were the predictors for receiving surgical treatment for PDA. Early ligation was significantly associated with a low incidence of culture-proven sepsis (p = 0.004), mechanical ventilator time > 4 weeks (p = 0.007), necrotizing enterocolitis stage (NEC) ≥ III (p = 0.022), and intraventricular hemorrhage (IVH) grade ≥ III (p = 0.035). Conclusions Early surgical ligation minimizes adverse effects of HSPDA in predicted infants who subsequently require surgical treatment for PDA. We suggest that predicted VLBWIs with HSPDA that is unresponsive to medical treatment should avoid delayed ductal closure to reduce severe NEC, severe IVH, culture-proven sepsis, and facilitate earlier endotracheal extubation.

Abstract
Background: ‘Ca. Aenigmarchaeota’ represents an evolutionary branch within the DPANN superphylum. However, their ecological roles and potential host-symbiont interactions are poorly understood.Results: Here, we analyze eight metagenomic-assembled genomes from hot spring habitats and reveal their functional potentials. Although they have limited metabolic capacities, they harbor substantial carbohydrate metabolizing abilities. Further investigation suggests that horizontal gene transfer might be the main driver that endows these abilities to ‘Ca. Aenigmarchaeota’, including enzymes involved in glycolysis. Additionally, members from the TACK superphylum and Euryarchaeota contribute substantially to the niche expansion of ‘Ca. Aenigmarchaeota’, especially genes related to carbohydrate metabolism and stress responses. Based on co-occurrence network analysis, we conjecture that ‘Ca. Aenigmarchaeota’ may be symbionts associated with TACK archaea and Euryarchaeota, though host-specificity might be wide and variable across different ‘Ca. Aenigmarchaeota’ genomes. Conclusion: This study provides significant insights into possible host-symbiont interactions and ecological roles of ‘Ca. Aenigmarchaeota’.

Abstract
Background. We performed the first clinical trial in China in which kidney transplantation was combined with donor hematopoietic stem cell (DHSC) infusion for tolerance induction. This study summarizes the 10-year follow-up results. Methods. From 2009 to 2017, 11 cases of living-related kidney transplantation combined with DHSC infusion were performed. Two of them were HLA-matched, and nine were HLA-mismatched. The DHSCs were mobilized using granulocyte colony-stimulating factor and harvested one day before transplantation. The recipients received consecutive total lymphoid irradiation for 3 days before kidney transplantation. The induction drug was anti-thymocyte globulin. DHSCs were infused on the 2 nd , 4 th and 6 th postoperative days. Results. One HLA-matched recipient induced 30-50% chimerism, and the others only induced less than 1% chimerism. Recipients had a low immune response to their donors while sustaining normal reactivity to non-donors in mixed lymphocyte reactions. All recipients were followed up for 717~3,918 days. One recipient lost allograft function, and 10 recipients had stable renal function. None of the 11 recipients had myelosuppression or graft-versus-host disease post transplantation. Our protocol did not increase the risk of infection. Allograft biopsy confirmed that one patient had mild acute rejection, and the other 10 recipients did not develop rejection. Five patients reduced the dose of immunosuppression. Conclusions. This study shows that long-term stable kidney allograft survival may be achieved with low-dose immunosuppression maintenance using our protocol.

Abstract
Background Intracranial aneurysms (IAs) are dangerous because of their potential to rupture. We previously found significant RNA expression differences in circulating neutrophils between patients with and without unruptured IAs and trained machine learning models to predict presence of IA using 40 neutrophil transcriptomes. Here, we aim to develop a predictive model for unruptured IA using neutrophil transcriptomes from a larger population and more robust machine learning methods. Methods Neutrophil RNA extracted from the blood of 134 patients (55 with IA, 79 IA-free controls) was subjected to next-generation RNA sequencing. In a randomly-selected training cohort (n=94), the Least Absolute Shrinkage and Selection Operator (LASSO) selected transcripts, from which we constructed prediction models via 4 well-established supervised machine-learning algorithms (K-Nearest Neighbors, Random Forest, and Support Vector Machines with Gaussian and cubic kernels). We tested the models in the remaining samples (n=40) and assessed model performance by receiver-operating-characteristic (ROC) curves. Real-time quantitative polymerase chain reaction (RT-qPCR) of 10 IA-associated genes was used to verify gene expression in a subset of 50 neutrophil RNA samples. We also examined the potential influence of demographics and comorbidities on model prediction. Results Feature selection using LASSO in the training cohort identified 37 IA-associated transcripts. Models trained using these transcripts had a maximum accuracy of 90% in the testing cohort. The testing performance across all methods had an average area under ROC curve (AUC)=0.97, an improvement over our previous models. The Random Forest model performed best across both training and testing cohorts. RT-qPCR confirmed expression differences in 8 of 10 genes tested. Gene ontology and IPA network analyses performed on the 37 model genes reflected dysregulated inflammation, cell signaling, and apoptosis processes. In our data, demographics and comorbidities did not affect model performance. Conclusions We improved upon our previous IA prediction models based on circulating neutrophil transcriptomes by increasing sample size and by implementing LASSO and more robust machine learning methods. Future studies are needed to validate these models in larger cohorts and further investigate effect of covariates.

Published: March 2020

Abstract
Background Mitofusin 2 (MFN2) is localized on the outer membrane of mitochondria and is closely related to the migration of malignant tumor cells. Estrogen receptor β (ERβ) plays an anticancer role in breast cancer. Our previous experiments showed that ERβ can induce MFN2 expression, which then inhibits breast cancer cell migration. However, the exact mechanism by which ERβ-induced MFN2 inhibits breast cancer cell migration is unknown. Methods In this study, immunohistochemistry was first used to detect the expression of MFN2 in breast cancer tissues, and its relationship with the clinicopathological characteristics and prognosis of breast cancer patients was analyzed. MCF-7 and MDA-MB-231 cells were transfected with ERβ and MFN2 knockdown or expression plasmids. Western blot was used to detect the effects of ERβ on MFN2 and MFN2 on P-AKT473 and MMP2; the P-AKT pathway inhibitor LY294002 was administered to cells transfected with MFN2 knockdown plasmids, Western blot, immunocytofluorescence, and a wound healing assay revealed the effect of MFN2 on its downstream signaling pathway and the migration of breast cancer cells. Results This study found that the expression of MFN2 is related to the molecular type and prognosis of breast cancer patients ( P <0.05). The positive expression rate of MFN2 in triple-negative breast cancer was significantly lower than that in the HER2 + and luminal types. However, MFN2 expression was unrelated to age, tumor size, lymph node metastasis, TNM stage, histological type and grade ( P >0.05); ERβ positively regulated MFN2 expression and reduced the migration of both MCF-7 and MDA-MB-231 cells, while MFN2 knockdown increased the expression of P-AKT473 and MMP2. In contrast, the overexpression of MFN2 inhibited the expression of P-AKT473 and MMP2. These results showed that in MFN2 knockdown cells treated with LY294002, P-AKT473 and MMP2 expression levels were reversed. The reversal of P-AKT473 and MMP2 expression levels inhibits the invasiveness of human breast cancer cells. Conclusion MFN2 is related to the molecular subtype and prognosis of breast cancer. In human breast cancer MCF-7 and MDA-MB-231 cells, ERβ-induced MFN2 can inhibit the P-AKT pathway, which inhibits the invasiveness and migration of both breast cancer cell lines.

Abstract
Background: Few studies have examined how maternal body mass index (BMI), mode of delivery and ethnicity affect the microbial composition of human milk and none have examined associations with maternal metabolic status. Given the high prevalence of maternal adiposity and impaired glucose metabolism, and the importance of human milk in the colonization of the infant gut, we systematically investigated the associations between these maternal factors and milk microbial composition and functionality. Methods: Women ≥20 years were recruited during pregnancy and milk samples were collected at 3 months post-partum (NCT01405547). Demographic data, weight, height, and a 3-hour oral glucose tolerance test were conducted at 30 (95% CI: 25-33) weeks gestation. Metagenomic DNA extraction and 16S ribosomal RNA gene sequencing of the V4 hypervariable region (Illumina MiSeq) was carried out on 113 milk samples. Results: Multivariable linear regression analyses demonstrated no significant associations between maternal characteristics (maternal BMI [pre-pregnancy, 3 months post-partum], glucose tolerance, mode of delivery and ethnicity) and microbiota alpha-diversity; however, pre-pregnancy BMI was associated with human milk beta-diversity (Bray-Curtis p=0.040). Women with a pre-pregnancy BMI >30 kg/m2 (obese) had a greater incidence of Bacteroidetes (incidence rate ratio [IRR]: 3.70 [95% CI: 1.61-8.48]) and a reduced incidence of Proteobacteria (0.62 [0.43-0.90]), compared to overweight women (BMI 25.0-29.9 kg/m2) as assessed by multivariable Poisson regression. Increased incidence of Gemella was observed among overweight (versus healthy) mothers with gestational diabetes (5.96 [1.85-19.21]) and obese (versus healthy) mothers with impaired glucose tolerance (4.04 [1.63-10.01]). An increased incidence of Brevundimonas (16.70 [5.99-46.57]) was found in the milk of women who underwent an unscheduled C-section versus vaginal delivery. Lastly, functional gene inference demonstrated that obesity was associated with increased abundance of genes encoding for the biosynthesis of secondary metabolites in milk (coefficient=0.00028, p=0.0070). Conclusions: Mother’s milk has a diverse microbiota of which its diversity and differential abundance appear associated with maternal body size, glucose tolerance status, mode of delivery, and ethnicity. Further research is warranted to determine whether this variability in the milk microbiota impacts colonization of the infant gut.
