Relationship of bisphenol A substitutes bisphenol F and bisphenol S with adiponectin/leptin ratio among children from the environment and development of children cohort. ENVIRONMENT INTERNATIONAL 2024; 185:108564. [PMID: 38467088 DOI: 10.1016/j.envint.2024.108564] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 02/28/2024] [Accepted: 03/04/2024] [Indexed: 03/13/2024]
Abstract
BACKGROUND Bisphenol A (BPA) is known as an obesogenic endocrine disruptor. Bisphenol S (BPS) and F (BPF) are substitutes that have recently replaced BPA. OBJECTIVES To investigate the relationships of urinary bisphenols (BPA, BPS and BPF) with adiposity measurements (obesity, BMI z-score, and fat mass), serum adipokine levels (adiponectin and leptin), and adiponectin/leptin ratio (A/L ratio) in 6- and 8-year-old children. METHODS A total of 561 children who participated in the Environment and Development of Children cohort (482 and 516 children visited at age 6 and 8, respectively) at Seoul National University Children's Hospital during 2015-2019 were included. Urinary BPA levels were log-transformed. BPS levels were categorized into three groups (non-detected, lower-half, and higher-half of detected), and BPF levels were classified into two groups (non-detected and detected). RESULTS The urinary BPS higher-half group had a higher BMI z-score (β = 0.160, P= 0.044), higher fat mass (β = 0.104, P< 0.001), lower adiponectin concentration (β =- 0.069, P< 0.001), higher leptin concentration (β = 0.360, P< 0.001), and lower A/L ratio (β =- 0.428, P< 0.001) compared with the non-detected group. The urinary BPF-detected group had a higher fat mass (β = 0.074, P< 0.001), lower adiponectin concentration (β =- 0.069, P< 0.001), higher leptin concentration (β = 0.360, P< 0.001), and lower A/L ratio (β =- 0.428, P< 0.001) compared with the non-detected group. The BPA levels showed no consistent associations with outcomes, except for isolated associations of BPA at age 6 with a higher BMI z-score at age 6 (P= 0.016) and leptin at age 8 (P= 0.021). CONCLUSIONS Increased exposure to BPS and BPF is associated with higher fat mass and leptin concentration, lower serum adiponectin, and lower A/L ratio in children. These findings suggest potential adverse effects of BPA substitutes on adiposity and adipokines. No consistent association of BPA exposure with outcomes could be partly explained by the decreasing BPA levels over time.

Abstract
Maternal obesity is associated with metabolic changes in mothers and higher risk of obesity in the offspring. Obesity in breastfeeding mothers appears to influence human milk production as well as the quality of human milk. Maternal obesity is associated with alteration of immunological factors concentrations in the human milk, such as C-reactive protein (CRP), leptin, IL-6, insulin, TNF-Alpha, ghrelin, adiponectin, and obestatin. Human milk is considered a first choice for infant nutrition due to the complete profile of macro nutrients, micro nutrients, and immunological properties. It is essential to understand how maternal obesity influences immunological properties of human milk because alterations could impact the nutrition status and health of the infant. This review summarizes the literature regarding the impact of maternal obesity on the concentration of particular immunological properties in the human milk.

Does breast milk adiponectin affect BMI and cardio-metabolic markers in childhood? Br J Nutr 2019; 121:905-913.

Abstract
Observational studies suggest that breast-feeding is associated with a more favourable BMI and cardio-metabolic markers, but potential underlying mechanisms are unclear. As serum adiponectin has an important function in adults for glucose and lipid metabolism, we assessed 251 participants of the Prevention and Incidence of Asthma and Mite Allergy birth cohort whether breast milk adiponectin is associated with childhood BMI and cardio-metabolic markers. We measured adiponectin levels in breast milk collected around 3 months after birth of the child and subsequently obtained weight and height repeatedly up to the age of 17 years. A medical examination (including blood pressure, glycated Hb and cholesterol) was performed at the age of 8, 12 and 16 years. We used multivariable mixed models to assess the association between breast milk adiponectin and BMI and cardio-metabolic markers at these ages. In models adjusted for exact age of breast milk collection, maternal age, presence of siblings, maternal BMI, pregnancy weight gain and child's birth weight, each unit increase in log breast milk adiponectin (in ng/ml) was associated with a 0·28 lower BMI z score (95 % CI -0·56, 0·00) at 3 months. After the age of 1 year, there was a tendency towards a higher BMI z score with increased breast milk adiponectin at some ages, but this pattern was not consistent throughout childhood. There were no associations between breast milk adiponectin and any of the cardio-metabolic markers in childhood. We conclude that in our study with follow-up until 17 years of age, breast milk adiponectin has no long-term effect on BMI and cardio-metabolic health during childhood.

Abstract
Acute lymphoblastic leukemia (ALL) is the most common pediatric malignancy. Dysregulation of adipokine pathways is implicated in the carcinogenesis and ALL. The aim of this study is to present the most recent data available regarding the role of leptin, adiponectin and ghrelin in the pathogenesis and prognosis of ALL. The PubMed database was searched using 'Leptin', 'Adiponectin', 'Ghrelin', 'Cancer', 'Children' and 'Acute Lymphoblastic Leukemia' as keywords. The majority of the studies indicated that leptin levels are increased and adiponectin levels are decreased in ALL children at diagnosis, as well as in ALL survivors. Ghrelin levels were found to be lower at diagnosis and progressively increased during treatment. Further research is warranted, as the heterogeneity of the current studies, various treatment protocols and differences in sample sizes make it difficult to deduce solid conclusions regarding the role of adipokines in ALL.

Abstract
BACKGROUND/AIMS Exposure to obesity during pregnancy may lead to adverse changes in the offspring's metabolic profile. We compared appetite- and growth-related hormones in a cohort of infants born to obese mothers (SKOT-II) with infants born mainly to nonobese mothers (SKOT-I). METHODS Infants from SKOT-I (n = 273) and SKOT-II (n = 132) were examined including anthropometric measurements and blood samples analyzed for glucose, insulin, insulin-like growth factor-I (IGF-I), adiponectin, and leptin. Information on breastfeeding and parental characteristics were also collected. RESULTS At 9 months of age, SKOT-II infants were 3.6% heavier and 1.2% longer than SKOT-I infants even though their mothers were shorter. There was no difference in body mass index (BMI). SKOT-II infants had higher levels of insulin, adiponectin, and leptin but lower levels of IGF-I compared to SKOT-I infants (all p ≤ 0.015). These differences remained, except for leptin, when adjusted for current weight. Breastfeeding versus nonbreastfeeding at 9 months was associated with lower concentrations of all hormones (all p ≤ 0.003). In adjusted models, maternal BMI at 9 months was positively associated with insulin and adiponectin and negatively with IGF-I. CONCLUSIONS Pre-pregnancy obesity confers symmetrically larger infant body size and higher levels of most growth- and appetite-related hormones but surprisingly lower levels of IGF-I, suggesting other possible infant growth-promoting effects through insulin.

Abstract
OBJECTIVE This cross-sectional study aimed to evaluate the association between leptin, insulin and adiponectin levels and anthropometric measurements of term newborns of adolescent and adult mothers. STUDY DESIGN Umbilical cord plasma samples were obtained from 80 healthy term neonates (40 from teenagers and 40 from adult mothers) and adiponectin, insulin and leptin concentrations were measured. RESULTS Cord plasma adiponectin levels were higher in the boys from adult mothers than in the boys of the adolescent (p < 0.05), while plasma leptin levels in the boys of the adults were significantly lower (p < 0.05) than those of girls from both groups. Univariate correlation analysis showed that leptin umbilical cord plasma levels were positively associated with birth weight in neonates from adolescents and adults. Multiple linear regression analysis revealed that leptin levels showed significant positive predictor for birth weight specifically in the adult mother. CONCLUSION Gestational age, but not adipokines, showed to be a significant positive predictor factor of birth weight in adolescent pregnancy.

Abstract
BACKGROUND Breast milk adiponectin could play a role in the regulation of infants' growth during lactation. AIM OF WORK The aim is to evaluate adiponectin concentration in human milk and to investigate its relationship with serum adiponectin concentration in lactating mothers and their breastfed infants and with anthropometric parameters of infants and mothers. MATERIALS AND METHODS Sixty healthy term infants and their healthy lactating mothers are included at infant age of 1 month then repeated again at the age of 4 months. All subjects included in this study were subjected to history, clinical examination, investigations including serum level of adiponectin of infants and their mothers by RIA test, human milk level of adiponectin by ELISA test. RESULTS There was a significant decrease in serum adiponectin of infant and mothers and maternal breast milk at the age of 4 months when compared to them at the age of 1 month. There was a significant positive correlation between infant serum adiponection, maternal serum adiponectin and breast milk adiponectin at infant's age of 1 month and at infant's age of 4 months. There was a significant negative correlation between maternal serum adiponectin and BMI of mothers. There was a significant negative correlation between infant serum adiponectin and their weight and length of infants at the age of 1 month and at the age of 4 months. CONCLUSIONS There's a metabolic link between mothers and their infants through breast milk during the first 6 months of life. A gradual decline in adiponectin level in maternal breast milk is associated with a gradual increase in infant growth up to 6 months of age.

Adiponectin profile and Irisin expression in Italian obese children: Association with insulin-resistance. Cytokine 2017; 94:8-13.

Abstract
Adiponectin (Acrp30), its high molecular weight (HMW) oligomers, and Irisin are molecules involved in several metabolic processes. To investigate if these cytokines could represent new metabolic markers, we evaluated the expression of Acrp30 and Irisin in serum of obese children from South Italy affected by different degrees of insulin resistance (IR). The anthropometric and metabolic features were evaluated in 27 obese children versus 13 age-matched controls. The expression of Acrp30, its pattern and Irisin were investigated by ELISA, western blotting and fast protein liquid chromatography. The HOMA index was significantly higher in obese children versus controls, and metabolic syndrome was more prevalent in obese children with elevated IR versus those with normal HOMA (38% vs 16%). Total Acrp30 and HMW oligomers were significantly lower in obese than in control children, and the difference was more pronounced in children with HOMA >3.4. In control and obese children, total Acrp30 and HMW oligomers were inversely related to HOMA (r-0.38, p 0.02; r-0.35, p 0.03). Irisin was significantly higher in obese than in control children, and was inversely correlated with Acrp30 and HMW (r-0.32, p 0.04; r-0.39, p 0.01). The inverse correlation of Acpr30 and HMW oligomers with HOMA indicates that Acpr30 is directly involved in IR status. Moreover, the inverse correlation between Irisin and Acrp30 and, more significantly, between Irisin and HMW oligomers suggests that the two cytokines are closely connected. The use of Acrp30, HMW oligomers and Irisin as predictive factors of IR in obese children remains to be further elucidated.

Abstract
SCOPE We studied in rats whether the expected detrimental effects in offspring associated to maternal dietary obesity may be reverted by obesogenic diet removal 1 month before mating. METHODS AND RESULTS Female rats were fed a cafeteria diet (CD) from days 10 to 100 and then a standard diet (SD) (postcafeteria rats). One month after CD removal, postcafeteria rats and a group of SD-fed female rats (controls) were mated with males. At weaning, offspring were fed SD and followed until 4 months old. CD was effective at inducing obesity in dams. Its removal led to a reduction in body weight, although, after 30 days, rats retained excess body weight and fat than controls. During lactation, postcafeteria dams showed greater body fat, and higher leptin and adiponectin levels in milk than controls. From 2 months of life, offspring of postcafeteria dams displayed lower body weight than controls, with no differences in the percentage of fat, homeostatic model assessment for insulin resistance, or circulating parameters. CONCLUSION Removal of CD in obese rats before gestation, although without complete reversion of body weight excess, may prevent the expected detrimental effects in offspring associated to an excess fat accumulation in adulthood and the related metabolic disturbances.

Cord Blood Adiponectin and Visfatin Concentrations in relation to Oxidative Stress Markers in Neonates Exposed and Nonexposed In Utero to Tobacco Smoke. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2016; 2016:4569108. [PMID: 27525051 PMCID: PMC4971318 DOI: 10.1155/2016/4569108] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/24/2016] [Revised: 06/06/2016] [Accepted: 06/16/2016] [Indexed: 12/17/2022]
Abstract
Aims. Maternal smoking is considered as a source of oxidative stress, which has been implicated to disrupted adipokines expression in adipose tissue. We examined the relationship between selected adipokines and markers of oxidative stress/antioxidant defence in the umbilical cord of neonates exposed and nonexposed in utero to tobacco smoke. Methods. Subjects including 85 healthy neonates (born to 41 smokers and 44 nonsmokers) were tested for adiponectin, visfatin, oxidized low density lipoprotein (ox-LDL), total oxidant capacity (TOC), and total antioxidant capacity (TAC). Results. Cord serum visfatin, ox-LDL, and TOC were significantly higher (p < 0.001) but adiponectin and TAC were lower (p < 0.001 and p < 0.05, resp.) in smoking group than in tobacco abstinents. In whole group of children (adjusted for smoking status, gender, and birth weight) adiponectin showed negative and visfatin positive correlations with ox-LDL. In the model estimated separately for smokers ox-LDL explained 36% of adiponectin and 35.5% of visfatin variance, while in the model of nonsmokers it explained 36.8% and 69.4%, respectively. Conclusion. Maternal smoking enhances oxidative status and depletes antioxidant potential in newborns. Lower level of adiponectin and higher visfatin concentration seem to be related with a less beneficial oxidative stress profile and higher level of lipid peroxidation in neonates exposed and nonexposed in utero to tobacco smoke.

Abstract
Prior studies have reported a significant, inverse association between adiponectin in human milk and offspring growth velocity. Less is known about this association in populations characterised by a loss of weight for age z-scores (WAZs) in early life. We investigated the association between maternal body composition and milk adiponectin in a sample of Filipino mothers. We then tested for an association between milk adiponectin and size for age in their infants. A total of 117 Filipino mothers nursing infants from 0 to 24 months were recruited from Cebu, Philippines. Anthropometrics, interviews and milk samples were collected and analysed using standard protocols. Mean milk adiponectin in this sample was 7.47 ± 5.75 ng mL(-1) . Mean infant WAZ and weight for length (WLZ) decreased with age. Maternal body composition was not associated with milk adiponectin content. Milk adiponectin had a significant, positive association with infant WAZ and WLZ. Prior reports have found an inverse association between milk adiponectin and infant WAZ. Here, we report that in lean populations with lower milk adiponectin, there is a positive association with infant WAZ, possibly reflecting pleiotropic biological functions of adiponectin for post-natal growth. This study increases the understanding of normal biological variation in milk adiponectin and the consequences of low levels of milk adiponectin for offspring growth.

Abstract
BACKGROUND AND AIMS New biomarkers potentially improve clinical management of cardiovascular disease, but there are gaps in understanding their role during childhood. Adiponectin regulates metabolism and exerts anti-inflammatory/anti-atherogenic effects. The aim of the study was to evaluate circulating levels of adiponectin during postnatal growth and its relationship with Brain Natriuretic Peptide (BNP) in healthy children, a marker of cardiac function known to be increased in childhood. METHODS AND RESULTS Plasma adiponectin and BNP were measured in 131 healthy children divided into: 43 newborns (0-3 days), 29 neonates (4-30 days), 25 infants (1-12 months) and 34 children (1-12 years). A group of 33 healthy adult subjects (25-60 years) was also studied. Plasma adiponectin in the 131 children resulted significantly higher compared to adult subjects (p < 0.0001). The time-course of adiponectin suggests the design of three age-based intervals: the first until 1 month of age (median 29.07 μg/mL, 11.61-47.01 μg/mL 5°-95° percentiles), the second between 1 and 12 months of age (21.66 μg/mL, 8.83-59.81 μg/mL) and the third for age up to 12 years (13.81 μg/mL, 4.10-28.57 μg/mL). Both adiponectin and BNP exhibited the same trend of a progressive decrease during growth, showing a significant relationship (Spearman's rho = 0.403, p < 0.0001). CONCLUSION Adiponectin plasma levels in a healthy pediatric population vary as a function of age. Three reference intervals for adiponectin in pediatric subjects have been indicated. The relationship between adiponectin and BNP suggests that the age-dependent profile of circulating adiponectin could also be due to BNP.

Abstract
AIMS The aims of the study were to determine human breast milk adiponectin concentration and to investigate its relationship with serum adiponectin concentration in lactating mothers and their infants and also to evaluate the relationship between serum adiponectin concentration and anthropometric parameters in nurses and infants. METHODS We enrolled 60 healthy term breastfed (BF) infants and their lactating mothers. Adiponectin was determined by radioimmunoassay test in serum and by enzyme-linked immunosorbent assay test in human milk (HM). Infants' and mothers' anthropometric parameters were measured. RESULTS Median (25‰, 75‰) adiponectin concentration in HM was 9.99 (3.59, 20.52) ng/mL. Serum adiponectin concentration in infants was 60.49 (45.76, 74.24) μg/mL and in lactating mothers 21.14 (12.61, 29.66) μg/mL. Adiponectin concentration in HM correlated positively with adiponectin in mothers' serum; r = 0.60 (p < 0.001) and in infants' serum r = 0.37 (p = 0.015). Adiponectin in HM correlated negatively with infants' age r = -0.3 (p = 0.04). Infants' serum adiponectin correlated negatively with their weight r = -0.35 (p = 0.005), length r = -0.35 (p = 0.006) and age r = -0.46 (p < 0.001) and mothers' serum adiponectin with their weight r = -0.37 (p = 0.02) and body mass index r = -0.45 (p = 0.004). CONCLUSIONS The observed correlations between adiponectin in mothers, HM and BF infants may be suggestive for a metabolic link between nurses and infants through milk.

Abstract
OBJECTIVE Adiponectin is a protein secreted by adipose tissue and involved in inflammatory process as well as in metabolic regulation. The aim of this study was to examine the response of plasma adiponectin to cardiac surgery in children with congenital defects to determine whether its measurement is associated to the response to injury. DESIGN AND METHODS Twenty-five pediatric patients undergoing heart surgery for correction of congenital defects were studied. Adiponectin plasma levels, obtained pre- and three times postoperatively, were determined by dedicated ELISA. Brain natriuretic peptide (BNP) plasma levels were also determined. RESULTS Adiponectin levels are highest in the first month of life (p=0.004 newborns vs. children) with a progressive fall in the next few years. After surgery, adiponectin increased slowly over a 1-month period, following an initial decrease in the first 3 days. CONCLUSIONS Adiponectin could be involved in the acute response to injury although further investigation into the relationship between adiponectin, glucose regulation and inflammatory process is necessary to examine the issue of the adiponectin decrease after surgery from a more integrated prospective.

Abstract
Mammalian studies report that methionine restriction (MR) as a dietary regimen extends life span, delays the onset of age-related diseases and enhances fat oxidation in obese subjects with metabolic syndromes. However, the underlying cellular signalling pathways are poorly understood. Rainbow trout (Oncorhynchus mykiss) is a glucose-intolerant species, providing an excellent model for the study of carbohydrate metabolism. MR diets in combination with 12 % (+/-) and 22 % (+/-) carbohydrate-rich meals were fed to rainbow trout for a period of 8 weeks and phenotypic and transcript expression changes in the liver and white muscle were assessed. Fish fed MR diets, irrespective of carbohydrate load, were shown to abolish the glucose-intolerant phenotype 6 h post-feeding. There was a distinct switch in glucose and glycogen content in the liver of fish fed MR diets, with a significantly higher concentration of glycogen, suggesting reduced glycolytic capacity. Transcriptional responses to MR demonstrated decreased expression of hepatic fatty acid synthase, sterol regulatory binding protein 1, PPARγ coactivator 1-α and PPARα, indicative of a reduction in the de novo synthesis of fatty acids and cholesterol, and a potential decrease in hepatic fat oxidative capacity. Muscle adenylate charge was depressed under MR, and increased expression of AMP-activated protein kinase α1 was detected, indicative of reduced energy availability. Total DNA methylation showed that carbohydrate load, rather than MR, dictated hypomethylation of genomic DNA. This is the first study which demonstrates that MR can abolish a glucose-intolerant phenotype in trout, and identifies trout as a suitable model for studying metabolic syndromes.

Abstract
Ghrelin and adiponectin have been found in breast milk and are considered to take part in the regulation of growth and energy metabolism of infants. Our aims were to determine ghrelin and adiponectin levels in breast milk and serum samples of mothers and their infants, and to investigate the relationship between their levels and anthropometry of newborn infants during early postnatal life. Total and active ghrelin and adiponectin levels were studied in breast milk, and the serum samples of 25 healthy lactating women and their healthy fullterm infants were taken at the 1st and 4th months of life. Anthropometric measurements of infants were also performed during the study period. Breast milk and infant serum active ghrelin levels were found to be significantly increased at the 4th month of life compared with 1st month levels (p < 0.05). Maternal serum total ghrelin and infant serum adiponectin levels were found to be significantly reduced at the 4th month of life (p < 0.05). Breast milk active ghrelin levels were higher than the infant and maternal serum active ghrelin at the 1st and 4th months (p < 0.05). There was a negative significant correlation between the level of infant serum active ghrelin levels and BMI of infants at the 1st month. A positive significant correlation was found between the level of 1st month infant serum adiponectin levels and weight gain of infants during the study period. Fourth month infant serum adiponectin were also positively correlated with weight and BMI of infants at the 4th month and the weight gain during study period. There was a positive significant correlation between the level of 4th month breast milk active ghrelin and weight gain of infants during the study period. Ghrelin and adiponectin are involved in postnatal growth of infants. Ghrelin in breast milk also seems to be related to the growth of infants during early postnatal life. The sources of these peptides in breast milk are probably both maternal serum and breast tissue itself.

Abstract
OBJECTIVE Serum adiponectin (APN) is associated with lower childhood obesity, and APN concentration in human milk is associated with slower growth during active breast-feeding. We examined infant weight gain in the second year of life after exposure to high or low levels of mother's milk APN. METHODS Breast-feeding mother-infant pairs were recruited in Mexico City and studied for 2 years; 192 infants with at least 12 months' follow-up were analyzed. Monthly milk samples were assayed for APN; mothers were classified as producing high or low levels of milk APN. Infant and maternal serum APN were assessed during year 1. Infant anthropometry was measured monthly (year 1) or bimonthly (year 2), and World Health Organization z scores were calculated. Longitudinal adjusted models assessed weight-for-age and weight-for-length z score trajectories from 1 to 2 years. RESULTS Maternal serum APN modestly correlated with milk APN (r=0.37, P<0.0001) and infant serum APN (r=0.29, P=0.01). Infants exposed to high milk APN experienced increasing weight-for-age and weight-for-length z scores between age 1 and 2 years in contrast to low milk APN exposure (P for group × time=0.02 and 0.054, respectively), adjusting for growth in the first 6 months and other covariates. In contrast, infant serum APN in year 1 was not associated with the rate of weight gain in year 2. CONCLUSIONS High human milk APN exposure was associated with accelerated weight trajectory during the second year of life, suggesting its role in catch-up growth after slower weight gain during the first year of life.

Abstract
OBJECTIVES The aims of this study were to determine interrelationships between serum leptin, adiponectin and resistin, insulin-like growth factor-1 (IGF-1), total antioxidant capacity (TAC), non-esterified fatty acids (NEFA) and phospholipids concentrations in infants. DESIGN AND METHODS A cross-sectional study was conducted to assess serum levels of leptin, adiponectin, resistin, IGF-1, TAC, NEFA and phospholipids in 45 breast-fed infants enrolled at 4-30 days after birth. RESULTS Serum leptin and adiponectin concentrations were positively correlated. Serum resistin concentrations were inversely correlated to serum leptin and adiponectin concentrations. Serum TAC was positively correlated to serum leptin and adiponectin, and inversely to serum resistin concentrations. Serum adiponectin concentrations were positively related to serum NEFA and phospholipid concentrations. Serum resistin concentrations were inversely related to serum NEFA, and phospholipid concentrations. CONCLUSION These data show that circulatory levels of leptin, adiponectin and resistin are interrelated and they apparently interact with the anti-oxidant system of infants.

Abstract
OBJECTIVES Adiponectin, adipocyte fatty acid-binding protein (AFABP), and leptin have been shown to be present in human breast milk (BM). We determined intraindividual changes of BM levels of these proteins during 12 months of lactation. SUBJECTS AND METHODS Proteins were measured using a high-sensitivity enzyme-linked immunosorbent assay method in 72 healthy mothers after delivery (day 0, D0) and after 1, 3, 6, and 12 months of lactation. RESULTS Adiponectin levels in BM on D0 were 22.8 ± 0.8 (mean ± standard error of the mean), in 1 month (M1) 22.0 ± 0.6, in 3 months (M3) 20.5 ± 0.6, in 6 months (M6) 21.4 ± 0.8, and in 12 months (M12) 25.7 ± 1.4 ng/mL. AFABP levels were 12.3 ± 2.0, 6.2 ± 1.3, 1.3 ± 0.2, 2.5 ± 1.0, and 4.6 ± 1.9 ng/mL, respectively. Leptin levels were 0.3 ± 0.04, 0.2 ± 0.03, 0.1 ± 0.01, 0.1 ± 0.02, and 0.2 ± 0.04 ng/mL, respectively. We found significantly higher levels of adiponectin in M12 in comparison to M3 and M6 (P = 0.0026), higher levels of AFABP in D0 and M1 when compared with M3, M6, and M12 (P < 0.0001), and higher levels of leptin on D0 than in M1, M3, M6, and M12 (P < 0.0001). AFABP levels correlated negatively with infants' body weight in M1, but there was no correlation throughout the lactation period between body weight and other proteins. We found positive correlation between adiponectin, AFABP, and leptin throughout the lactation. CONCLUSIONS All of the hormones were detectable in BM up to 12 months of lactation, with decreasing trend until M3 and subsequent increase till M12. We speculate that higher levels in M6 and M12 may be caused by longer intervals between breast-feeding due to the introduction of complementary food.

Abstract
OBJECTIVE The aim of the study was to characterize early nutritional and microbiological environments (maternal colostrum adiponectin concentration and early gut microbiota composition) in children subsequently becoming normal weight versus overweight. PATIENTS AND METHODS Fifteen overweight children at 10 years of age were identified from an ongoing prospective nutrition, allergy, mucosal immunology and intestinal microbiota project. Normal-weight children (n = 15), matched for sex, gestational age and body mass index at birth, mode of delivery, probiotic intervention, and duration of breast-feeding, were identified from the same cohort as controls. To characterize the early dietary environment we analyzed the adiponectin concentration in the maternal colostrum. With an aim to assess the initial microbiological environment, we analyzed the gut microbiota composition by fluorescent in situ hybridization in these children at the age of 3 months. Additionally, putative early markers of low-grade inflammation, such as serum-soluble innate microbial receptor sCD14, were analyzed at the age of 3 months. RESULTS The colostrum adiponectin concentration was significantly higher in mothers whose children were normal weight than in those whose children were overweight at the age of 10 years (P = 0.001). In parallel, the normal-weight children had significantly higher sCD14 concentrations in the serum (P = 0.049) and tended to have higher bifidobacterial numbers in the gut microbiota (P = 0.087) at the age of 3 months. CONCLUSIONS The results of the present study suggest that early dietary and gut microbiological environments have a more complex effect on the metabolic programming of a child than previously anticipated.

Abstract
We have developed a multi-channel 3D microfluidic cell culture system (multi-channel 3D-microFCCS) with compartmentalized microenvironments for potential application in human drug screening. To this end, the multi-channel 3D-microFCCS was designed for culturing different 3D cellular aggregates simultaneously to mimic multiple organs in the body. Four human cell types (C3A, A549, HK-2 and HPA) were chosen to represent the liver, lung, kidney and the adipose tissue, respectively. Cellular functions were optimized by supplementing the common medium with growth factors. However, TGF-beta1 was found to enhance A549 functions but inhibit C3A functions. Therefore, TGF-beta1 was specifically controlled-released inside the A549 compartment by means of gelatin microspheres mixed with cells, thus creating a cell-specific microenvironment. The function of A549 cells was enhanced while the functions of C3A, HK-2 and HPA cells were uncompromised, demonstrating the limited cross-talk between cell culture compartments similar to the in vivo situation. Such a multi-channel 3D-microFCCS could be potentially used to supplement or even replace animal models in drug screening.

Abstract
This study examined the association of insulin resistance with single-nucleotide polymorphism (SNP) 276G>T at adiponectin gene and the plasma long-chain polyunsaturated fatty acids (LCPUFAs) profile in obese children. One hundred thirty-one normolipidaemic obese children aged 8-13 y (53 girls and 68 boys) entered the study. The prevalence of T allele carriers at SNP276 was 48.8%. Mean [SD] values of fasting insulin and homeostasis model assessment-insulin resistance (HOMA-IR) index in noncarriers versus carriers of T allele were 12.4 [6.4] versus 20.6 [6.3] muU/mL (p = 0.039) and 2.6 [1.4] versus 4.5 [1.7] (p = 0.032). Mean [SD] values of plasma C18:3n - 3, C20:5n - 3/C20:4n - 6, and n - 6/n - 3 LCPUFA in phospholipids in noncarriers versus carriers of T allele were 0.10 [0.04] versus 0.08 [0.03] % (p = 0.013), 0.04 [0.01] versus 0.03 [0.01] % (p = 0.045), and 4.4 [0.7] versus 4.9 [0.9] % (p = 0.005), respectively. Insulin resistance was independently associated with SNP 276G>T (p = 0.002) and n - 6/n - 3 LCPUFA (p = 0.042) in plasma phospholipids, and interaction was found between SNP 276G>T and n - 6/n - 3 LCPUFA (p = 0.046). These findings suggest that obese children carriers of the SNP 276G>T may be at increased risk of metabolic complications compared with noncarriers, possibly due in part to a different plasma phospholipids profile.

Abstract
BACKGROUND/AIMS Steatosis may trigger hepatocytes to up-regulate CD95/Fas thereby increasing susceptibility to apoptosis, inflammation and fibrosis. We investigated this concept and potential roles of adiponectin and its receptors (AdipoR1; AdipoR2) in chronically HCV-infected patients. METHODS In 98 HCV+ patients and 20 controls, sera were tested for HCV genotypes, FFAs, adiponectin and the M30 apoptosis indicator, and biopsies were evaluated for steatosis/inflammation/fibrosis, CD95/Fas (mRNA/protein), adiponectin (mRNA/protein), AdipoR1/-R2 (mRNA) and M30 (protein). We also questioned whether adiponectin protects HepG2 hepatoblastoma cells from FFA-triggered CD95/Fas up-regulation and apoptosis. RESULTS Patients [HCV clades 1 (78%), 2 (3%) and 3 (19%)] revealed increased FFA and adiponectin serum levels (p = .005). Hepatocyte CD95/Fas up-regulation correlated with steatosis, inflammation and fibrosis (p = .004). Advanced fibrosis correlated significantly (p = .05) with serum M30. Liver adiponectin correlated with steatosis (p = .016), CD95/Fas (p < .001) and inflammation/fibrosis. Hepatocyte AdipoR2 mRNA specifically correlated with serum adiponectin and steatosis (p = .003), while hepatocyte AdipoR1 mRNA dropped in pronounced fibrosis (p = .060). Finally, adiponectin protected HepG2 cells from FFA-triggered CD95/Fas expression and induction of apoptosis (p = .0396). CONCLUSIONS In chronic HCV infection, steatosis up-regulates hepatocyte CD95/Fas and thus increases apoptosis, which facilitates inflammation and fibrosis. The physiologic countermeasure of adiponectin up-regulation may offer clues for future therapeutic intervention.
