Arch Oral Biol 2014; 59:800-7. [PMID: 24859767 DOI: 10.1016/j.archoralbio.2014.04.009] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2014] [Revised: 03/19/2014] [Accepted: 04/13/2014] [Indexed: 02/01/2023]
Abstract
BACKGROUND Plasma levels of polyunsaturated fatty acids (PUFAs) are different before and after periodontal treatment. Asians and Westerners have significantly different baseline levels of plasma PUFAs. However, no Asian study has reported the effects of nonsurgical treatment on the correlation between periodontal condition and plasma levels of PUFAs. We analyzed whether recovery from periodontitis was correlated with the elevation of plasma fatty acids 3 months after the nonsurgical intervention and with no recommended supplements. DESIGN Thirty-five Taiwanese patients with periodontitis were recruited. Probing pocket depths (PPDs) and clinical attachment levels (CALs) were measured at baseline and 3 months after the nonsurgical treatment. Plasma levels of fatty acids were determined using gas chromatography. Differences and correlations between plasma fatty acid composition and periodontitis severity at baseline and 3 months after treatment were determined. RESULTS Twenty-six patients completed the study. At the baseline, PPDs were negatively correlated with plasma n-3 PUFAs (r=-0.52, p<0.01), but at 3 months post intervention, periodontitis severity had declined and the weight percentages of n-3 PUFAs, DPA, and DHA were significantly (p=0.019, 0.005, and 0.037, respectively) higher. The recovery percentages of CALs were positively and significantly correlated with plasma ΔPUFAs and the percentage of Δn-3 PUFAs in ΔPUFAs (r=0.42 and 0.45, respectively; p<0.05 for both). CONCLUSIONS We conclude that a higher weight percentage of n-3 PUFAs in total PUFAs was related to the recovery of CALs 3 months after the nonsurgical periodontal treatment. However, no such relationship was found for PPDs.

Association of n-3 polyunsaturated fatty acids and inflammatory indicators with renal function decline in type 2 diabetes. Clin Nutr 2014; 34:229-34. [PMID: 24721145 DOI: 10.1016/j.clnu.2014.02.009] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2013] [Revised: 02/15/2014] [Accepted: 02/26/2014] [Indexed: 11/16/2022]
Abstract
BACKGROUND & AIMS The n-3 polyunsaturated fatty acids (PUFAs) and the inflammatory indicator, interleukin-6 (IL-6), have been implied in the development of renal dysfunction. This longitudinal study examined the effect of n-3 PUFAs and IL-6 on the risk of renal function decline and explored whether n-3 PUFAs modify the effect of inflammatory indicators on renal dysfunction risk in type 2 diabetes. METHODS Studying 676 type 2 diabetic patients, we analyzed erythrocyte fatty acids and inflammatory markers in 2008 and estimated glomerular filtration rate (eGFR) in 2008 and 2012. Renal function decline was defined as an eGFR decline of ≥25% over a 4-year period. RESULTS Multivariable logistic regression revealed erythrocyte total PUFAs, n-3 PUFAs, and n-3/n-6 PUFA ratio correlated negatively with risk of renal function decline (OR = 0.75, 0.78, and 0.61, respectively, all p < 0.01), while n-6 PUFAs did not. IL-6 independently predicted risk of renal dysfunction (OR = 1.18, p = 0.015). Stratifying erythrocyte PUFAs into low (<50(th) percentile) or high group (≥50(th) percentile), we found a positive association between IL-6 and risk of renal dysfunction only in the low n-3 PUFA (OR = 1.27, p = 0.035), low n-3/n-6 PUFA (OR = 1.27, p = 0.034), and low total PUFA groups (OR = 1.36, p = 0.005), but not in the high groups. CONCLUSIONS High PUFA concentrations, especially n-3 or higher n-3/n-6 PUFA ratio, may exert protective effects against renal function impairment in type 2 diabetic patients. Whether the effect is mediated via modification of inflammatory biomarker such as IL-6 by high n-3 PUFA status warrants further investigation.

Abstract
Background The metabolic effect of fructose in sugar-sweetened beverages (SSB) has been linked to de novo lipogenesis and uric acid (UA) production. Objectives This study investigated the biological effects of SSB consumption on serum lipid profiles and retinol-binding protein 4 (RBP4) among Taiwanese adolescents. Methods We evaluated the anthropometric parameters and biochemical outcomes of 200 representative adolescents (98 boys and 102 girls) who were randomly selected from a large-scale cross-sectional study. Data were analyzed using multiple regression models adjusted for covariates. Results Increased SSB consumption was associated with increased waist and hip circumferences, body mass index (BMI) values and serum UA, triglyceride (TG) and RBP4 levels. Adolescents who consumed >500 ml/day of beverages half-to-heavily sweetened with high-fructose corn syrup (HFCS) exhibited TG and RBP4 levels 22.7 mg/dl and 13.92 ng/ml higher than non-drinkers, respectively. HFCS drinkers with hyperuricemia had higher TG levels than HFCS drinkers with normal UA levels (98.6 vs. 81.6 mg/dl). The intake of HFCS-rich SSBs and high value of BMI (≥24) interactively reinforced RBP4 levels among overweight/obese adolescents. Circulating RBP4 levels were significantly correlated with weight-related outcomes and TG and UA concentration among HFCS drinkers (r = 0.253 to 0.404), but not among non-drinkers. Conclusions High-quantity HFCS-rich beverage consumption is associated with higher TG and RBP4 levels. Hyperuricemia is likely to intensify the influence of HFCS-rich SSB intake on elevated TG levels, and in overweight and obese adolescents, high BMI may modify the action of fructose on higher circulating levels of RBP4.

Abstract
AIMS Serum ferritin has been found closely related with diabetes and glucose metabolism, but its impact on diabetic nephropathy remains unknown. This study aimed to explore the association between serum ferritin and microalbuminuria in Type 2 diabetes. METHODS Eight hundred and fifty-one subjects with Type 2 diabetes were selected from a cohort participating in a glycaemic control study in Taiwan in 2008. We used urine albumin:creatinine ratio to define microalbuminuria; serum ferritin was divided into quartiles for analysis. Logistic regression and trend tests were used to delineate the association between serum ferritin and microalbuminuria. RESULTS Subjects with diabetes with higher ferritin tended to have more metabolic disorders, higher high-sensitivity C-reactive protein and higher prevalence of microalbuminuria. Compared with those in the lowest quartile, subjects with diabetes in the highest ferritin quartile were 55% (P = 0.029) more likely to have microalbuminuria. After controlling for demographics, metabolic profiles and other inflammatory markers, the association between serum ferritin levels and microalbuminuria remained significant (P for trend < 0.001). This independent relationship was not changed either for those who had better glycaemic control or those who had not used an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker. CONCLUSIONS The current study shows hyperferritinemia may be an independent risk factor of nephropathy in patients with Type 2 diabetes.

Abstract
Severe early childhood caries (SECC) is a public health problem among preschool children. Malnutrition is a condition commonly prevalent in children with SECC. This study investigated the nutritional status among preschool children with SECC. Children with SECC (n = 101) aged 2-5 years from the Division of Pediatric Dentistry in an academic hospital in Southern Taiwan were recruited for our cross-sectional study. The nutritional status of the children was assessed based on anthropometric measurements and clinical tests. By applying the criteria established by the World Health Organization, we found that 9% and 46% of the children with SECC were diagnosed as being anemic and iron deficient, respectively. Using national standards for the body mass index, 30% of children with SECC were classified as underweight. The relationship between the caries status of the children and anemia was examined using multivariable logistic regression analysis (p < 0.05). Our results show that SECC is strongly associated with anemia (7.25-fold), indicating that clinicians and dentists should provide treatment to improve both the oral hygiene and the nutritional status of children with SECC.

Abstract
AIMS/HYPOTHESIS HbA(1c) variability has been shown to be an independent risk factor for nephropathy in patients with type 1 diabetes. In this study, we aimed to explore the association between HbA(1c) variability and microalbuminuria development in patients with type 2 diabetes. We also intended to test the applicability of serially measured HbA(1c) over 2 years for this risk assessment. METHODS Between 2003 and 2005, we recruited 821 middle-aged normoalbuminuric individuals with type 2 diabetes and followed them through to the end of 2010. The average follow-up time was 6.2 years. We defined microalbuminuria as a urine albumin to creatinine ratio of 30 mg/g (3.4 mg/mmol) or higher. HbA(1c) variability was calculated by the SD of serially measured HbA(1c). The Cox proportional hazards model was used to evaluate the association between HbA(1c) SD quartile and development of microalbuminuria. RESULTS The incidence of microalbuminuria for the overall population was 58.4, 58.6, 60.8 and 91.9 per 1,000 person-years for Q1- to Q4-adjusted HbA(1c) SD, respectively (p for trend = 0.042). Compared with patients in Q1, those in Q4 were about 37% more likely to develop microalbuminuria. The HR derived from a series of 2 year HbA(1c) measurements was similar to that from data collection for longer than 4 years. CONCLUSIONS/INTERPRETATION In addition to mean HbA(1c) values, HbA(1c) variability, even measured as early as 2 years, is independently associated with the development of microalbuminuria in patients with type 2 diabetes.

Abstract
Long chain polyunsaturated fatty acids (LC-PUFA), ARA (arachidonic acid, 20:4n-6) and DHA (docosahexaenoic acid, 22:6n-3) have positive effects and environment pollutants, polychlorinated dibenzo-p-dioxins/dibenzofurans(PCDD/F) and polychlorinated biphenyls (PCB) have negative effects on neural development during early life. Placental dioxin/PCB serves as markers for cumulative exposure to fetus. Fatty acid composition of placenta depends on nutrient supply during pregnancy, serving as indicators for fetal ARA and DHA accretion. This study investigated correlation between placental PCDD/F and PCB toxic equivalent (TEQ) and LC-PUFA in 34 pregnant women from Taiwan. Placental PCDF TEQ were inversely correlated with placental ARA (p=0.020), C20:3n-6 (p=0.01), C22:4n-6 (p=0.04), C22:5n-6 (p<0.01) and with DHA (p=0.03), but ARA and DHA did not vary with PCDD, dioxin-like and indicator PCB. After adjustment for age and body mass index, a one-unit PCDF TEQ increase was associated with 1.021%w/w and 0.312%w/w decreases in ARA (β=-1.021, p=0.03) and DHA (β=-0.312, p=0.03). Since ARA and DHA were unrelated to three classes of toxins, and a weak negative association was found with PCDF, these data provide no basis for discouraging marine fish consumption during pregnancy for Taiwan women on the basis of these organics. Pregnant women should consume fish for its unique package of nutrients while avoiding few species with high organic pollutant or mercury contamination.

Abstract
OBJECTIVE An association between insulin resistance and microalbuminuria in type 2 diabetes has often been found in cross-sectional studies. We aimed to reassess this relationship in a prospective Taiwanese cohort of type 2 diabetic subjects. RESEARCH DESIGN AND METHODS We enrolled 738 normoalbuminuric type 2 diabetic subjects, aged 56.6 ± 9.0 years, between 2003 and 2005 and followed them through the end of 2009. Average follow-up time was 5.2 ± 0.8 years. We used urine albumin-to-creatinine ratio to define microalbuminuria and the homeostasis model assessment of insulin resistance (HOMA-IR) to assess insulin resistance. The incidence rate ratio and Cox proportional hazards model were used to evaluate the association between HOMA-IR and development of microalbuminuria. RESULTS We found incidences of microalbuminuria of 64.8, 83.5, 93.3, and 99.0 per 1,000 person-years for the lowest to highest quartiles of HOMA-IR. Compared with those in the lowest quartile of HOMA-IR, the incidence rate ratios for those in the 2nd, 3rd, and highest quartiles were 1.28 (95% CI 0.88-1.87), 1.44 (0.99-2.08), and 1.52 (1.06-2.20), respectively (trend test: P < 0.001). By comparison with those in the lowest quartile, the adjusted hazard ratios were 1.37 (0.93-2.02), 1.66 (1.12-2.47), and 1.76 (1.20-2.59) for those in the 2nd, 3rd, and highest HOMA-IR quartiles, respectively. CONCLUSIONS According to the dose-response effects of HOMA-IR shown in this prospective study, we conclude that insulin resistance could significantly predict development of microalbuminuria in type 2 diabetic patients.

Abstract
AIMS Cigarette smoking is a well-known risk factor associated with diabetic nephropathy. The objective of this study was to further investigate the dose-response effect of tobacco exposure on proteinuria in males with Type 2 diabetes. METHODS Five hundred and nine males with Type 2 diabetes were selected from a cohort participating in a glucose control study in Taiwan. Pack-years of cigarette smoking were calculated to define tobacco exposure. Proteinuria was identified if albumin-to-creatinine ratio was > or = 30 mg/g in at least two of three consecutive urine tests. Logistic regression and trend tests were used to delineate the association between smoking status and proteinuria. RESULTS Compared with non-smokers, those who had smoked 15-30 or more than 30 pack-years were respectively 2.78 (95% CI 1.34-5.76, P < 0.01) and 3.20 (95% CI 1.74-5.86, P < 0.001) times more likely to develop proteinuria. The dose-response effect of tobacco exposure on the development of proteinuria is highly significant in all subjects (P = 0.001) and in subgroups with relatively short duration of diabetes mellitus (P < 0.001), good blood pressure control (P = 0.001) and those of young age (P = 0.007). CONCLUSIONS The current study shows a clear dose-response effect of cigarette smoking on development of proteinuria in male Type 2 diabetic patients. These findings reinforce the urgent need to encourage diabetic patients to stop smoking regardless of age, duration of diabetes mellitus or status of blood pressure control.

Abstract
OBJECTIVE In this randomized controlled trial we evaluated the effect of registered dietitian-led management of diabetes on glycemic control and macronutrient intake in type 2 diabetic patients in primary care clinics in Taiwan and studied the association between changes in macronutrient intake and glycemic measures. RESEARCH DESIGN AND METHODS We recruited 154 adult patients with type 2 diabetes and randomly assigned them to a routine care control group (n = 79) or a registered dietitian-led intervention group (n = 75) who received on-site diabetic self-management education every 3 months over 12 months. RESULTS Over the 1-year period, neither the intervention group (n = 75) nor the control group (n = 79) had significant changes in A1C, whereas the intervention patients with poorly controlled baseline A1C (> or =7%) (n = 56) had significantly greater improvements in A1C and fasting plasma glucose than the control subjects (n = 60) (-0.7 vs. -0.2%, P = 0.034; -13.4 vs. 16.9 mg/dl, P = 0.007) during the same period. We also found significant net intervention-control group differences in overall energy intake (-229.06 +/- 309.16 vs. 56.10 +/- 309.41 kcal/day) and carbohydrate intake (-31.24 +/- 61.53 vs. 7.15 +/- 54.09 g/day) (P < 0.001) in patients with poorly controlled A1C. Multivariable adjusted modeling revealed an independent association between changes in carbohydrate intake and A1C in the intervention group (n = 56; beta = 0.10, SEM = 0.033, P = 0.004). CONCLUSIONS On-site registered dietitian-led management of diabetes can improve glycemic control in patients with poorly managed type 2 diabetes in primary care clinics in Taiwan. A reduction in carbohydrate intake may improve glycemic status.

Abstract
Genetic variants in alcohol dehydrogenase-1B (ADH1B) and aldehyde dehydrogenase-2 (ALDH2) genes modulate acetaldehyde removal upon alcohol ingestion. Although these genetic vulnerabilities have been linked to higher esophageal squamous cell carcinoma (ESCC) risks, it is unclear whether they also determine the time of malignancy presentation. The purpose of this investigation was to unravel genotoxic effects of the two alcohol-metabolizing genes with regard to alcohol and tobacco consumption on the age at ESCC diagnosis and tumor dissemination. ADH1B/ALDH2 genotyping was performed on lymphocyte DNA specimens taken from 406 consecutively registered incident patients with pathology-proven ESCC. To fully utilize individual genetic and survival information, survival analyses and gene-longevity applied approaches were introduced. Among heavy drinkers, the ADH1B Arg/Arg (55 years) and ALDH2 Glu/Lys genotypes (54 years) were found to confer a 15 and 16 years earlier carcinoma diagnosed age than His/His and Glu/Glu nondrinkers (both 70 years), respectively. For drinkers, 1-year age advancement was, separately, associated with a 0.977 and 0.953-fold stepwise reduced likelihood of being ADH1B Arg homozygote and ALDH2 Lys variant. Noticeably elevated hazard-ratio (HR) for drinkers of ADH1B slow-form genotype and ALDH2 inactive-form allele were identified in smokers (HR = 2.3-2.6), but no in nonsmokers. In smokers, appreciably higher cumulative cancer onset risks were correspondingly recognized from the age of 45 and 49 upward among any + Lys allele and Arg/Arg + Glu/Glu combined-ADH1B/ALDH2-genotype drinkers than nondrinkers. In conclusion, consumption of tobacco and alcohol, coupled with genetic susceptibilities associated with acetaldehyde elimination, as modulated by ADH1B and ALDH2 genotypes, determines a substantial magnitude of tumorigenetic effect on earlier age ESCC diagnosis.

Abstract
BACKGROUND/PURPOSE The outcome analysis of obese patients undergoing laparoscopic cholecystectomy (LC) in Asia-Pacific countries is rarely reported. This study examined associations between body mass index (BMI) and clinical outcomes of elective LC in Taiwan. METHODS A total of 627 patients with gallbladder disease due to gallstones undergoing LC were divided into three groups based on BMI: <25.0 kg/m2 (normal, NO; n = 310), 25.0-29.9 kg/m2 (overweight, OW; n = 252), and >30 kg/m2 (obese, OB; n = 65). RESULTS Both overweight and obesity were not associated with conversion and complication rates. The conversion rates of the three groups were 5.5 (NO), 6.0 (OW), and 4.6% (OB), and the complication rates were 3.2 (NO), 2.4% (OW), and 4.6% (OB), respectively. However, overweight and obesity were related to a trend toward longer operating time (NO 67.4 +/- 31.8; OW 77.8 +/- 35.6; OB 79.0 +/- 37.9 min) (P trend <0.001). One death (BMI 40.6 kg/m2) was due to septic complications. In the multivariable logistic analysis, only acute cholecystitis, but not BMI, was a predictor for conversion and complications. CONCLUSIONS Based on these results, it appears that BMI was not associated with clinical outcomes and that LC is a safe procedure in obese patients with uncomplicated gallstone disease in Taiwan.

Abstract
The prevalence of hypertriglyceridemia, considered to be an independent risk factor for the development of cardiovascular disease, is high in Taiwanese aborigines. This study was undertaken to examine the effect of the -1131T>C polymorphism in the apolipoprotein A5 gene on serum triglyceride levels in female Taiwanese aborigines. This was a cross-sectional study, and a total of 316 unrelated female Taiwanese aborigines were genotyped at the -1131T>C polymorphism in apolipoprotein A5 using the polymerase chain reaction-restriction fragment length polymorphism method. Serum triglyceride > or = 150 mg/dL was defined as the hypertriglyceridemia group and triglyceride < 150 mg/dL was considered to be the control group. The frequency of the minor C allele was significantly higher in the hypertriglyceridemia group (0.53) than in the control group (0.35) (p < 0.001). The frequency of this rare allele was comparable to that in Japanese and Han Chinese, but was higher than that in Caucasians. In a multiple logistic model adjusted for possible confounders, C allele-containing variants were independently associated with greater risks (CT genotype: OR = 3.28, 95% CI = 1.43-7.56; CC genotype: OR = 5.86, 95% CI = 2.15-15.99) of hypertriglyceridemia than the TT genotype (p < 0.01), notably with the CC homozygote exhibiting the greatest risks. The genotype polymorphisms were also associated with serum triglyceride concentrations in a linear fashion (for trend, p < 0.05). Our results indicate that the -1131T>C polymorphism of the Apo A5 gene influences serum triglyceride levels in female Taiwanese aborigines, and that differences exist in the frequency of the C allele among people of various ethnicities.

Abstract
The consumption of alcohol, tobacco and betel quid has been found to be an important contributor to esophageal squamous cell carcinoma (ESCC) in Taiwan. The genotoxic effect of the ADH1B and ALDH2 genes modulating an individual's alcohol-metabolizing capacity on ESCC may be linked to drinking behavior, intake pattern and other exogenous factors. To investigate the interplay of these genetic and environmental factors in determining the risk of ESCC, a multicenter case-control study was conducted. Here, 406 patients with pathology-proven ESCC, as well as 656 gender, age and study hospital matched controls were recruited. Genetic polymorphisms of ADH1B and ALDH2 appeared to correlate with the abstinence of alcohol, though not with tobacco and betel quid. Within the same levels of alcohol consumption, carcinoma risks increased along with an increase in the numbers of ADH1B*1 and ALDH2*2 alleles. The inactive ALDH2*1/*2 genotype was found to multiplicatively interact with a low-to-moderate (0.1-30 g/day) and a heavy (>30 g/day) ethanol intake to increase the ESCC risk (the joint aOR = 14.5 and 102.6, respectively). Among low-to-moderate drinkers, a smoking-dependent carcinogenetic effect for the ADH1B*1/*1 and ALDH2*1/*2+*2/*2 genotypes was recognized, with significant risks found in smokers, but not in nonsmokers. Further, a supra-multiplicative combined risk of ESCC for alcohol and tobacco use was identified among carriers of the ADH1B*1/*1 genotype (p for interaction = 0.042). In conclusion, the interplay of the ADH1B and ALDH2 genotypes, in conjunction with a behaved drinking habit and a practiced drinking pattern, along with continued tobacco consumption, plays an important pathogenic role in modulating ESCC risk.

Abstract
OBJECTIVES Dietary energy and protein play important roles in chronic kidney disease (CKD). This study investigates the relationship between energy/protein intake status and renal function in CKD. DESIGN AND STUDY POPULATION This cross-sectional study included 599 adult patients diagnosed with stage 3 to 5 CKD in nephrology and nutrition outpatient clinics in Taiwan. MAIN OUTCOME MEASURE Energy and protein intakes were assessed using 24-h dietary recall. We recorded recommended calorie/protein amounts and renal function indices, glomerular filtration rate (GFR), creatinine, and blood urea nitrogen (BUN). Patients were categorized into three intake calorie/protein groups by a ratio of actual intake vs. recommended intake. High intake was defined as a ratio of actual intake/recommended intake > or = 110%, moderate intake as > or = 90% to <110%, and low intake as <90%. Data were analyzed by paired t test, one-way analysis of variance, least significant differences, and multiple linear regression. RESULTS The energy and protein intakes in CKD patients were significantly higher and lower than recommended levels (P < .001). Low energy intake was significantly related to worsening GFR at increments of -4.41 mL/min/1.73 m(2), compared with moderate and high energy intake (P = .008); high protein intake was also associated with worsening GFR at increments of -3.50 mL/min/1.73m(2), compared with moderate and low protein intake (P < .001). Low energy intake and high protein intake were significantly positively correlated with elevations in creatinine and BUN. CONCLUSION Lower energy and higher protein intakes than recommended may be associated with deteriorating renal function.

Abstract
Docosahexaenoic acid (DHA) and arachidonic acid (ARA) are commonly added to infant formula worldwide; however, dietary concentrations needed to obtain optimal tissue levels have not been established. Hence, we studied tissue responses in piglets fed various doses of DHA and ARA. Doses were 0, 1, 2, and 5 times those used in U.S. infant formulas and DHA/ARA in Diet 0, Diet 1, Diet 2, and Diet 5 were 0, 4.1/8.1, 8.1/16.2, and 20.3/40.6 mg/100 kJ formula, respectively. Supplementation of dietary DHA and ARA increased DHA in brain, retina, liver, adipose tissue, plasma, and erythrocyte by 1.1- to 25.8-fold of Diet 0 (P-trend < 0.01). Tissue ARA (1.1- to 6.0-fold of Diet 0) responded to dietary ARA in liver, adipose tissue, plasma, and erythrocytes (P-trend < 0.05); brain and retina ARA was, however, unresponsive to dietary DHA and ARA. Plasma and erythrocyte DHA were positively associated with DHA in neural (brain and retina) and visceral (liver and adipose) tissues (r(2) = 0.11-0.56; P < 0.001-P = 0.042). Plasma and erythrocyte ARA did not correlate with neural ARA. Only plasma ARA was associated with liver ARA (r(2) = 0.222; P = 0.02) and adipose ARA (r(2) = 0.867; P < 0.001) and erythrocyte ARA correlated with adipose ARA (r(2) = 0.470; P < 0.001). We conclude that dietary DHA supplementation affords an effective strategy for enhancing tissue DHA, ARA in visceral but not neural tissues is sensitive to dietary ARA, and erythrocyte and plasma DHA can be used as proxies for tissue DHA, although blood-borne ARA is not an indicator of neural ARA.

Abstract
The purpose of this study was to characterize differentially expressed transcripts associated with varying rates of egg production in Taiwan country chickens. Ovarian follicles were isolated from two strains of chicken which showed low (B) or high (L2) rates of egg production, then processed for RNA extraction and cDNA library construction. Three thousand and eight forty clones were randomly selected from the cDNA library and amplified by PCR, then used in microarray analysis. Differentially expressed transcripts (P<0.05, log(2)> or = 1.75) were sequenced, and aligned using GenBank. This analysis revealed 20 non-redundant sequences which corresponded to known transcripts. Eight transcripts were expressed at a higher level in ovarian tissue prepared from chicken strain B, and 12 transcripts were expressed at a higher level in L2 birds. These differential patterns of expression were confirmed by semi-quantitative RT-PCR. We show that transcripts of cyclin B2 (cycB2), ferritin heavy polypeptide 1 (FTH1), Gag-Pol polyprotein, thymosin beta4 (TB4) and elongation factor 1 alpha1 (EEF1A1) were enriched in B strain ovarian follicles. In contrast, thioredoxin (TXN), acetyl-CoA dehydrogenase long chain (ACADL), inhibitor of growth family member 4 (ING4) and annexin II (ANXA2) were expressed in at higher levels in the L2 strain. We suggest that our approach may lead to the isolation of effective molecular markers that can be used in selection programs in Taiwan country chickens.

Abstract
OBJECTIVE Human uncoupling proteins 2 and 3 (UCP2 and UCP3) are two mitochondrial proteins that are involved in the control of metabolism of fatty acid and possibly protect against oxidative damage. The aim of this study was to analyze genetic associations of four polymorphisms of the UCP2 and UCP3 genes with insulin, leptin concentration and obesity in Taiwan aborigines. RESEARCH METHODS Four polymorphisms were compared in 324 obese (body mass index (BMI) > or =30 kg/m(2)) and overweight (30>BMI > or =25 kg/m(2)) subjects, and 114 normal weight subjects (BMI <25 kg/m(2)) in an aboriginal community of southern Taiwan. Anthropometric characteristics and fasting levels of insulin, leptin, triglycerides and cholesterol were measured. RESULTS Before and after adjusting for age distribution, only the Val55 allele in exon 4 of the UCP2 gene increased the risk of overweight and obesity (adjusted odds ratio (OR)=2.02, P=0.004) in comparison with Ala55. UCP2 V55V is also associated with higher fasting insulin levels than A55V (P=0.01) and A55A (P=0.04) in the obese/overweight group. Using the COCAPHASE program of the UNPHASED software, haplotype analysis of three single nucleotide polymorphisms (A55V-G866A-C-55T) revealed that A-G-C (73% in obese subjects and 77% in controls) was the most common haplotype and that the haplotype V-A-T (13% in obese subjects and 5% in controls) was significantly increased in obese and overweight subjects (BMI > or =25 kg/m(2)) (OR=2.62, P<0.001). DISCUSSIONS UCP2 A55V variant might predispose to obesity and Val55 allele to confer population-attributable risk for 9.5% of obese disorders and increase insulin concentrations. The V-A-T haplotype within UCP2-UCP3 gene cluster is also significantly associated with obesity in Paiwan aborigines.
