“…In mammals, SIRT1 can be activated by RSV, a natural polyphenol (Lagouge et al, 2006;Jiang et al, 2020). Previous studies have confirmed the role of RSV on SIRT1 activation in blunt snout bream (Zhang et al, 2018) and largemouth bass (Liu et al, 2021). In the present study, the inclusion of 1.0 and 2.5‰ RSV significantly elevated the protein expression of SIRT1, which was in accordance with its expression in the transcription level (Liu et al, 2021).…”

“…Sequences (5'-3') Primer information 16:00) for 10 weeks. At the end of the feeding experiment, ten fish were randomly selected from each tank, after 24 h of starvation and anaesthetization with eugenol, to separate serum samples as described in Liu et al (2021). Then, liver samples of four fish were separated for proximate composition and enzymatic activity analysis, and liver samples of the remaining six fish were isolated for gene expression and Western blot analysis.…”

Sirtuin 1 (SIRT1) of largemouth bass (Micropterus salmoides) was cloned and characterized in the present study and the influence of SIRT1 activation induced by resveratrol inclusion on the expression of genes related to lipid metabolism and antioxidation was also investigated. The SIRT1 of largemouth bass, with full-length cDNA sequence of 3395bp encoding 695 amino acids, was mainly expressed in gonad, heart and liver. The analysis of multiple sequence alignment revealed that, in accordance with other species, SIRT1 of largemouth bass contained highly conserved substrate-binding site and NAD+ binding site. The result of subcellular localization displayed that SIRT1 of largemouth bass was mainly localized in the nucleus. The inclusion of 1.0 and 2.5‰ dietary RSV, a natural SIRT1 activator, significantly elevated the SIRT1 protein expression. Meanwhile, the phosphorylation of AKT1 and FoxO1 followed similar pattern with that of SIRT1, indicating the activation of insulin pathway, which may result in the inhibition of lipogenesis and activation of lipolysis, and reduced hepatic triglycerides content. Additionally, the activation of SIRT1 induced by dietary RSV elevated the antioxidant capacity at both transcriptional level and enzymatic level, which was probably mediated by the transcription factor Nrf2. In above, SIRT1 was suggested to be involved in improving antioxidant capacity and alleviating hepatic lipid deposition in largemouth bass.

“…Taking the obvious co-linearity of BSA and BMI with height and weight into account, BSA was frequently used to study the relationship between physiological factors and TVOL, since the correlation between BSA and TVOL was relatively strong (28) . Few studies have compared the magnitude of the effect of height and weight on TVOL, like our previous study reported that the effect of height on TVOL may be expressed through factors such as age and weight (29) . In this study, after excluding the interaction between height and weight, the TVOL of heavy weight children was significantly larger than that of light weight children in different age groups across all three height levels, whereas the TVOL of tall height children did not differ from that of short height children in the inferior weight level and superior weight level at age 8.…”

Comparative analysis of five correction methods for thyroid volume by ultrasound and their recommended reference values in Chinese children aged 8–10 years

et al. 2022

Considering the influence of body’s growth and development on thyroid volume (TVOL), whether five existed corrected methods could be applied to correct TVOL remains unclear, in terms of Chinese children’s increased growth and development trends. This study aimed to compare the applicability of five correction methods for TVOL: Body Surface Area corrected Volume (BSAV), Body Mass Indicator corrected Volume (BMIV), Weight and Height corrected Volume Indicator (WHVI), Height corrected Volume Indicator 1 (HVI1) and Height corrected Volume Indicator 2 (HVI2); to establish the reference values for correction methods. The data of Iodine Nutrition and Thyroid Function Survey was used to analyse the differences in TVOL between normal and abnormal thyroid function children. Data of National Iodine Deficiency Disorders Survey were used to compare five correction methods and to establish their reference values. The median urinary iodine concentration of children surveyed were 256.1μg/L in 2009 and 192.6μg/L in 2019, respectively. No significant difference was found in TVOL and thyroid goitre rate between children with normal and abnormal thyroid function. In the determination of goitre, HVI1, HVI2, BSAV and BMIV all showed high agreement with TVOL, while the area under the ROC curve (AUC) of WHVI was relatively low for children aged 8(AUC=0.8993) and 9(AUC=0.8866). Most differences of TVOL between light and heavy weight, short and tall height children can be eliminated by BSAV correction. BSAV was the best method of TVOL correction in this research. Reference values were established for corrected thyroid volumes in Chinese children aged 8-10 years by sex.

“…Zou Y's study found that BSA and age were positively correlated with TVOL (8). A recent study in Liu's showed that TVOL was influenced by age, weight, coverage rate of iodized salt (CRIS), and salt iodine content (SIC) (16). With improved living conditions, children's physical development has improved in China.…”

The purpose of this study was to research the factors influencing thyroid volume (TVOL) in 6∼12-year-old children and update the reference values. A cross-sectional study was carried out in iodine-sufficient areas of four provinces in China. Urine, edible salt, and drinking water samples were collected from children. Children’s height, weight, and TVOL were measured. Ridge regression was used to screen variables for solving the multicollinearity problem. Quantile regression was used to analyze the relationship between the quantiles of TVOL and other variables. In total, 5653 children aged 6∼12 years were enrolled in this study, including 2838 boys and 2815 girls. There was no significant difference in TVOL between boys and girls (P>0.05). Spearman correlation analysis showed that total TVOL was positively correlated with age, height, weight, BSA and BMI, and the correlation coefficients were 0.614, 0.625, 0.646, 0.653 and 0.488 respectively. Among them, the correlation between TVOL and BSA was the strongest. According to the ridge regression results, age and body surface area (BSA) influenced TVOL, and the ridge regression coefficients were 0.13 and 0.94 respectively. Quantile regression further showed that age and BSA had significant influences on the whole TVOL distribution (P<0.001). Therefore, the TVOL of children aged 6∼12 years in China was mainly influenced by age and BSA, and reference values for TVOL of different genders based on age and BSA were established.
