Supplementary Material for: Characterization and Differential Expression Patterns of Conserved microRNAs and mRNAs in Three Genders of the Rice Field Eel (Monopterus albus)

<p>MicroRNAs (miRNAs) are endogenous small RNAs that can regulate target mRNAs by binding to their sequences in the 3′ untranslated region. The expression of miRNAs and their biogenetic pathway are involved in sexual differentiation and in the regulation of the development of germ cells and gonadal somatic cells. The rice field eel <i>(Monopterus albus)</i> undergoes a natural sexual transformation from female to male via an intersex stage during its life cycle. To investigate the molecular mechanisms of this sexual transformation, miRNAs present in the different sexual stages of the rice field eel were identified by high-throughput sequencing technology. A significantly differential expression among the 3 genders (p < 0.001) was observed for 48 unique miRNAs and 3 miRNAs*. Only 9 unique miRNAs showed a more than 8-fold change in their expression among the 3 genders, including mal-miR-430a and mal-miR-430c which were higher in females than in males. However, mal-miR-430b was only detected in males. Several potential miRNA target genes <i>(cyp19a, cyp19b, nr5a1b, foxl2 amh</i>, and<i> vasa)</i> were also investigated. Real-time RT-PCR demonstrated highly specific expression patterns of these genes in the 3 genders of the rice field eel. Many of these genes are targets of mal-miR-430b according to the TargetScan and miRTarBase. These results suggest that the miR-430 family may be involved in the sexual transformation of the rice field eel.</p

Supplementary Material for: Higher risk of sarcopenia in older adults with type 2 diabetes: NHANES 1999-2018

Introduction: Recent studies suggested that sarcopenia may be a significant comorbidity of diabetes mellitus (DM). Nonetheless, studies with nationally representative data are scarce, and the changing trend of sarcopenia prevalence over time is largely unknown. Therefore, we aimed to estimate and compare the prevalence of sarcopenia in diabetic and non-diabetic United States (US) older population, and to explore the potential predictors of sarcopenia as well as the trend of sarcopenia prevalent in the past decades. Methods: Data was retrieved from the National Health and Nutrition Examination Survey (NHANES). Sarcopenia and DM were defined according to corresponding diagnosis criteria. Weighted prevalence was calculated and compared between diabetic and non-diabetic participants. The differences among age and ethnicity groups were explored. Results: A total of 6381 US adults (>50 years) were involved. The overall prevalence of sarcopenia was 17.8% for US elders, and the prevalence was higher (27.9% vs. 15.7%) in those with diabetes ones than those without. Stepwise regression revealed that sarcopenia was significantly associated with DM (Adjusted odds ratio=1.37, 95%CI: 1.08-1.22; P<0.05) after controlling for potential confounders including gender, age, ethnicity, educational level, BMI and muscle strengthening activity. A slightly fluctuate but overall increasing trend of sarcopenia prevalence was observed among diabetic elders while no obvious changing trend was observed in their counterparts in recent decades. Conclusion: Diabetic US older adults face significantly higher risk of sarcopenia when compared with their non-diabetic counterparts. Gender, age, ethnicity, educational level and obesity were important influencing factors of sarcopenia development

Erratum: Development and Validation of a New Dry Weight Estimation Method Using Single Frequency Bioimpedance in Hemodialysis Patients

<i>Background:</i> We proposed a new method to estimate dry weight (DW) using single frequency bioimpedance. <i>Methods:</i> We hypothesized that the change in whole body resistance at 50 kHz (R₅₀) was proportional to the ultrafiltration volume (UFV) during a hemodialysis (HD) session. When the targeted resistance estimated in healthy subjects was reached, the patient achieved his/her DW. UFV and R₅₀ were monitored in 40 HD patients. Another 43 HD patients were stratified into 2 groups to validate this method. <i>Results:</i> The change in whole body resistance was proportional to UFV in each of the 40 HD patients. In the DW_decrease group, pre-dialysis systolic blood pressure (n = 29, 154.5 ± 22.8 vs. 146.9 ± 22.3, p < 0.05) and antihypertensive medicine (4.7 ± 3.6 vs. 3.3 ± 2.2, p < 0.05) decreased without adverse symptoms change. In the DW_increase group, the number of adverse symptoms in 1 week (n = 14, 26 vs. 6, p < 0.05) decreased without a change in systolic blood pressure. <i>Conclusion:</i> This method may become a convenient and cheaper way to estimate DW in HD patients

Supplementary Material for: Association between Triglyceride-Glucose Index and 1-year Recurrent Stroke after Acute Ischemic Stroke: Results from the Xi’an Stroke Registry Study of China

Introduction: The triglyceride-glucose (TyG) index is reported to be related to poor functional outcomes and all-cause mortality post-stroke. However, the association between TyG index and recurrent stroke after acute ischemic stroke (AIS) has not been well described. We aimed to identify whether the TyG index was associated with 1-year recurrent stroke after AIS. Methods: Baseline patient information was collected at admission, and the TyG index was calculated. Recurrent stroke events were followed up at 1, 3, 6, and 12 months after diagnosis. We then examined the association between the TyG index and risk of 1-year recurrent stroke using multivariable Cox regression models and restricted cubic spline analyses. Results: Among 2,288 participants, the mean TyG index was 8.8 0.7. Those in the fourth quartile (Q4) demonstrated higher recurrent stroke risk than those in Q1 (adjusted hazard ratio [HR] = 1.63; 95% confidence interval [CI], 0.98–2.72; p = 0.059). Subgroup analysis revealed a sex-specific association between TyG index and recurrent stroke (p for interaction = 0.022). Additionally, restricted cubic splines analyses showed a non-linear association between the TyG index and 1-year recurrent stroke. In females, patients in the Q4 had a 2.95-fold increased recurrent stroke risk than did patients in the Q1 (adjusted HR =2.95; 95% CI, 1.09–7.94; p = 0.032); the risk increased when the TyG index was > 8.73. However, no significant correlation was observed in males. Conclusion: A non-linear association was found between the TyG index and 1-year recurrent stroke risk. Subsequently, a high TyG index could predict an increased 1-year recurrent stroke risk in female AIS patients
