Methods Male SD rats were divided into six groups and fed respectively with a conventional diet and the YT diet （one of the five experimental diets） supplemented with two vitamin mixtures （Mix.1： vitamins A, E, and folic acid; Mix.2：mix.1 plus riboflavin and vitamin C） at two different doses. On the 30th day, sera were collected from the rats and added into a medium for cell culture, with 10% FBS used as a serum control. The effects were assessed by MTT assay, DNA synthesis and flow cytometry assays. Results Compared with the control, the sera from rats fed with the YT diet significantly promoted the proliferation of Eca-109 cells, which was, however, reversed by the supplementation with two vitamin mixtures at high doses. Surprisingly, the same treatment produced contrary effects on HL7702 cells as compared with Eca-109 cells. Conclusion The sera from rats fed with the YT diet could promote the proliferation of human esophageal cancer cell line Eca-109, whereas the sera from those fed with the YT diet supplemented with vitamin mixtures might have inhibitory effects on the proliferation of Eca-109 ceils.展开更多

To convey this concept more appropriately, partial endocrine deficiency in the aging male (PEDAM) was introduced as a term for the phenomenon of hormonal alterations in the aging male. Hormones responsible for some of the manifestations associated with male aging are testosterone, growth hormone, dehydroepiansdrosterone (DHEA), melatonin, thyroid hormones and leptin. Of these, testosterone has been widely investigated and its beneficial and adverse effects on male bodily systems are relatively well established. However, a serious body of confusion and misunderstandings surrounding the diagnosis, treatment and monitoring of men suspected of having androgen deficiency has been raised. Therefore, it is timely to provide practical criteria for diagnosis and treatment to avoid misconception about the use of testosterone in the aging male. To provide an understanding and information of the issues, the following headings are summarized: (1) Important clinical consideration on testosterone supplementation in the aging male; (2) Asian practical recommendations on testosterone supplementation in the aging male.展开更多

Methods A total of 40 subjects with the same Fokl VDR genotype were randomly divided into two groups： one received calcium tablet （600 mg once daily as CaCO3） and the other placebo tablet once daily for 1 year. At baseline, BMD was measured by dual-energy X-ray absorptiometry at lumbar spine （L2-L4） and at left hip whereas serum PICP, serum OC, and urinary CTX, serum 25（OH）VitD3, and serum estradiol were measured at weaning and I year thereafter. Results After the intervention, BMD at lumbar spine and at left hip increased significantly in all these women with a trend among different Fokl VDR genotypes such as FF 〉 Ff 〉 ff （P〈O.05, 〈0.01, and 〈0.001, respectively）. BMD at lumbar spine in women with FF VDR genotype increased much more rapidly than in those with ff VDR genotype （P〈0.05）. Compared with the control group women with the FF genotype regained more BMD after calcium supplementation （P〈0.05）. Conclusion Daily calcium 600 mg supplementation has beneficial effect on the bone health of women with FF VDR genotype.展开更多

Methods Ninety-four pubertal girls were recruited in the study and divided into two groups and three sub-groups according to the ER-α PvulI polymorphisms. One year before and after calcium supplementation, bone mineral density （BMD） was measured by DEXA, while BGP, BAP, TRACP5b, and 25-OH-VitD3, as well as estrogen were detected by ELISA. Analysis of covariance was used to examine the effect of ER-ct polymorphisms on bone development. Results The absolute increase and percentage change of BGP were significantly higher in the supplemented group than in the control group （P〈0.05）. In the intervened group, The increase and percentage change of the total body and radio distal 1/3 BMD were higher in PP than in PP genotype （P〈0.05）, and the increase of BAP in Pp was also higher than PP in the same group （P〈0.05）. Conclusion PP genotype shows a better response to calcium supplementation than the other Pvull polymorphisms.展开更多

Bread was prepared from varying proportions of 100%, 99%, 98%, 97%, 96% and 95% wheat flour supplemented with 0%, 1%, 2%, 3%, 4% and 5% Moringa oleifera leaf powder respectively. The bread samples were allowed to cool at ambient temperature (30℃± 1℃) and analysed for some physical properties, proximate composition, and sensory attributes. Moringa leaf powder addition significantly (p % to 3.28%), ash (1.10% to 1.65%), protein (9.07% to 13.97%), and ether extract (1.51% to 2.59%), while decreasing moisture content (35.20% to 27.65%). Moringa leaf powder supplementation also significantly (p cm3, 32.32 to 25.65 g, 7.00 to 5.83 cm and 4.70 to 2.65 cm3/g respectively, while the loaf weight increased from 169.20 to 185.86 g. There was a significant (p mg/100g and 0.02 to 3.27 mg/100g respectively, while Iron (Fe) and Cupper (Cu) contents decreased from 2.74 to 1.25 mg/100g and 2.26 to 0.03 mg/100g respectively. Sensory evaluation showed that although there was significant (p Moringa supplementation. This implies that despite the high nutrient content of Moringa oleifera powder, it is not a good substitute for wheat in bread production due to its physical characteristics and sensory attributes.展开更多

Total 40 sheep, allowed free consumption of MUS after grazing, served as a treatment group, while 30 sheep, fed only by pasture grazing, served as a control group. Ruminal fermentation parameters, consisted of pH, Bacterial Crude Protein （BCP） and ammonia nitrogen （NH3-N） were measured. In addition, numbers of five symbiotic bacteria were investigated. The results showed as follows： the average daily weight gain, concentration of NH3-N and numbers of protozoa were significantly higher （p〈0.05） in the treatment group than those in the control group. Contrastingly, no significant difference was found in BCP concentration and pH between the two groups. At the end of the experiment, the populations of Selenomonas ruminantium, Anaerovibrio lipolytica, Fibrobacter succinogenes, Ruminococcus flaveciens and Ruminococcus albus in the treatment group were significantly higher than those of the control group （p〈0.05）. These results demonstrated that greater weight gain could be induced during winter in Inner Mongolia by improved nutritional status through promotion of microbial populations using urea and sugar.展开更多

文摘Synthesis of zinc oxide nanoparticles(ZnO-NPs)via green method is an outstanding alternative to conventional/regular methods;however,the safety or toxicity of the biosynthesized ZnO-NPs in vivo is not fully explored.This study was conducted to evaluate the protective efficiency of cinnamaldehyde-loaded chitosan nanoparticles(Cin@CSNPs)against oxidative damage and genotoxicity of ZnO-NPs in mice.ZnO-NPs were biosynthesized using the extract of fresh leaves of Mentha pulegium L.Cin was extracted from cinnamon essential oil,and was loaded into chitosan nanoparticle(Cin@CSNPs).Both ZnO-NPs,Cin@CSNPs and CSNPs were characterized.The in vitro release of Cin@CSNPs was determined.In the biological study,6 groups of male BALB/c mice were treated by gavage for 3 weeks as follows,control group,the group received ZnO-NPs(25 mg/kg b.w),the groups received Cin@CSNPs at low dose(50 mg/kg b.w)or high dose(100 mg/kg b.w),and the groups received ZnO-NPs plus Cin@CSNPs at the 2 tested doses.Blood and tissue samples were collected for different biochemical,genetical and histological studies.The particle size of ZnO-NPs,CSNPs,and Cin@CSNPs were(20.78±2.60),(170.0±3.7),and(218.23±2.90)nm,andξ-potential were(32.7±4.6),(8.32±0.27)and(4.80±0.21)mV,respectively.ZnO-NPs disturbed the biochemical and oxidative stress indices,AFP,CEA,TNF-α,chromosomal aberrations in somatic and germ cells,and sperm abnormality along with severe pathological changes in the hepatic,renal,and testicular tissues.Cin@CSNPs improved significantly all the parameters tested and the histological picture in a dose-dependent.Therefore,the biosynthesized ZnO-NPs exhibit oxidative damage and genotoxicity,and Cin@CSNPs have potential protective effects against the risks of ZnO-NPs and may be a promising tool to overcome the challenges of using Cin in food and pharmaceuticals applications.
文摘Objective Epidemiological studies have shown that vitamin D status affects glycemic control in individuals with type 2 diabetes mellitus(T2DM).However,findings from intervention studies remain inconsistent.Therefore,a network meta-analysis was conducted to evaluate the comparative efficacy of various vitamin D supplementation strategies on glucose indicators in adults with T2DM.Methods Eligible studies published before September 12,2024,were retrieved from PubMed,EMBASE,Cochrane Library,and Web of Science.A network meta-analysis of multiple dosage strategies—low(<1,000 IU/day,LDS),medium(1,000–2,000 IU/day,MDS),high(2,000–4,000 IU/day,HDS),and extremely high(≥4,000 IU/day,EHDS)—was performed.Results The network meta-analysis of 40 RCTs indicated that,compared with placebo,vitamin D_(3)supplementation increased 25-hydroxyvitamin D[25-(OH)-D]levels,with pooled mean difference(MD)showing a stepwise increase from LDS to EHDS.Ranking probabilities showed a corresponding rise in 25-(OH)-D levels from LDS(46.7%)to EHDS(91.2%).EHDS reduced fasting blood glucose(FBG)relative to no treatment.LDS significantly decreased hemoglobin A1c(HbA1c),and vitamin D_(2) significantly affected FBG levels.MDS led to a significant change in fasting insulin(FIN)compared to both placebo(MD:-4.76;95%CI-8.91 to-0.61)and no treatment(MD:-7.30;95%CI-14.44 to-0.17).Conclusion The findings suggest that vitamin D supplementation may be a viable approach for improving glycemic control in adults with T2DM,with lower doses potentially offering benefit.The analysis also showed a dose-dependent increase in 25-(OH)-D levels.
文摘BACKGROUND Perinatal depression affects 10%-20%of pregnant women and subsequently influences maternal health and fetal development.Concerns over the safety of antidepressants during pregnancy have prompted the exploration of nutritional interventions as adjunct therapies.This study evaluated the impact of combining preconception and prenatal supplementation with myo-inositol,probiotics,and trace elements on mood,quality of life,and fetal development in depressed mothers.This retrospective cohort study included 314 pregnant women who were diag-nosed with mild to moderate depression,as determined by a Zung self-rating depression scale score of less than 69.The participants were divided into an intervention group(n=161)receiving myo-inositol,probiotics,and trace elements and a control group(n=153)without supplementation.Supplementation comm-enced 3 months before conception and continued through pregnancy.Psychiatric symptoms and quality of life were evaluated using the positive and negative affect schedule-now,state-trait anxiety inventory,Patient Health Ques-tionnaire-8,and World Health Organization Quality of life Assessment:Brief Version scales preconception and postpartum.Fetal development metrics were assessed via ultrasound,and neonatal outcomes were recorded.RESULTS The intervention group presented significant reductions in gestational diabetes mellitus(13.04%vs 23.53%,P=0.016)and gestational hypertension(3.73%vs 9.15%,P=0.049).Higher levels of inositol,iron,zinc,and probiotics were observed near term in the intervention group.Postpartum mood assessments indicated lower anxiety and depression scores for the intervention group,with significant improvements in the positive and negative affect schedule-now(P=0.002),trait anxiety(P=0.002),and Patient Health Questionnaire-8(P=0.018)scores.The World Health Organization Quality of life Assessment:Brief Version scores improved in the psychological(P=0.041)and environmental(P=0.009)domains postpartum.Fetal biparietal diameter and femoral length were greater in the intervention group alongside better neonatal body length and reduced neonatal unit admissions(2.48%vs 7.84%,P=0.031).CONCLUSION Combined supplementation with myo-inositol,probiotics,and trace elements from preconception through pregnancy may reduce pregnancy-related complications,enhance mood and quality of life,and improve fetal growth metrics.

文摘Objective To study the effects of a local diet popular in Yanling region （YT diet） on the proliferation of two human cell lines （Eca-109 esophageal squamous cell carcinoma line and HL7702 normal liver epithelial cell line） in rats by a sero-physiological approach. Methods Male SD rats were divided into six groups and fed respectively with a conventional diet and the YT diet （one of the five experimental diets） supplemented with two vitamin mixtures （Mix.1： vitamins A, E, and folic acid; Mix.2：mix.1 plus riboflavin and vitamin C） at two different doses. On the 30th day, sera were collected from the rats and added into a medium for cell culture, with 10% FBS used as a serum control. The effects were assessed by MTT assay, DNA synthesis and flow cytometry assays. Results Compared with the control, the sera from rats fed with the YT diet significantly promoted the proliferation of Eca-109 cells, which was, however, reversed by the supplementation with two vitamin mixtures at high doses. Surprisingly, the same treatment produced contrary effects on HL7702 cells as compared with Eca-109 cells. Conclusion The sera from rats fed with the YT diet could promote the proliferation of human esophageal cancer cell line Eca-109, whereas the sera from those fed with the YT diet supplemented with vitamin mixtures might have inhibitory effects on the proliferation of Eca-109 ceils.
文摘<abstract>Profound and diffuse alterations in the production of gonadal and adrenal androgens as well as growth hormone are associated with aging. To convey this concept more appropriately, partial endocrine deficiency in the aging male (PEDAM) was introduced as a term for the phenomenon of hormonal alterations in the aging male. Hormones responsible for some of the manifestations associated with male aging are testosterone, growth hormone, dehydroepiansdrosterone (DHEA), melatonin, thyroid hormones and leptin. Of these, testosterone has been widely investigated and its beneficial and adverse effects on male bodily systems are relatively well established. However, a serious body of confusion and misunderstandings surrounding the diagnosis, treatment and monitoring of men suspected of having androgen deficiency has been raised. Therefore, it is timely to provide practical criteria for diagnosis and treatment to avoid misconception about the use of testosterone in the aging male. To provide an understanding and information of the issues, the following headings are summarized: (1) Important clinical consideration on testosterone supplementation in the aging male; (2) Asian practical recommendations on testosterone supplementation in the aging male.

文摘Objective To investigate the effect of calcium supplementation on bone mineral density （BMD） in Chinese women with different Fokl vitamin D receptor （VDR） genotypes （FF, Ff, and ff） after weaning or resumption of menstruation during lactation. Methods A total of 40 subjects with the same Fokl VDR genotype were randomly divided into two groups： one received calcium tablet （600 mg once daily as CaCO3） and the other placebo tablet once daily for 1 year. At baseline, BMD was measured by dual-energy X-ray absorptiometry at lumbar spine （L2-L4） and at left hip whereas serum PICP, serum OC, and urinary CTX, serum 25（OH）VitD3, and serum estradiol were measured at weaning and I year thereafter. Results After the intervention, BMD at lumbar spine and at left hip increased significantly in all these women with a trend among different Fokl VDR genotypes such as FF 〉 Ff 〉 ff （P〈O.05, 〈0.01, and 〈0.001, respectively）. BMD at lumbar spine in women with FF VDR genotype increased much more rapidly than in those with ff VDR genotype （P〈0.05）. Compared with the control group women with the FF genotype regained more BMD after calcium supplementation （P〈0.05）. Conclusion Daily calcium 600 mg supplementation has beneficial effect on the bone health of women with FF VDR genotype.

文摘Microalgae has been consumed in human diet for thousands of years.It is an under-exploited crop for production of dietary foods.Microalgae cultivation does not compete with land and resources required for traditional crops and has a superior yield compared to terrestrial crops.Its high protein content has exhibited a huge potential to meet the dietary requirements of growing population.Apart from being a source of protein,presence of various bio-active components in microalgae provide an added health benefit.This review describes various microalgal sources of proteins and other bio-active components.One of the heavily studied group of bio-active components are pigments due to their anticarcenogenic,antioxidative and antihypertensive properties.Compared to various plant and floral species,microalgae contain higher amounts of pigments.Microalgal derived proteins have complete Essential Amino Acids(EAA)profiles and their protein content is higher than conventional sources such as meat,poultry and dairy products.However,microalgal based functional foods have not flooded the market.The lack of awareness coupled with scarce incentives for producers result in under-exploitation of microalgal potential.Application of microalgal derived components as dietary and nutraceutical supplements is discussed comprehensively.

文摘Objective To investigate the association of estrogen receptor alpha （ER-c0 PvulI polymorphisms with the effect of calcium supplementation on bone development in Chinese pubertal girls, and to study the importance of calcium supplementation by maximizing the peak bone mass at their pubertal stage for bone development and osteoporosis prevention and the role of estrogen in regulating bone mass. Methods Ninety-four pubertal girls were recruited in the study and divided into two groups and three sub-groups according to the ER-α PvulI polymorphisms. One year before and after calcium supplementation, bone mineral density （BMD） was measured by DEXA, while BGP, BAP, TRACP5b, and 25-OH-VitD3, as well as estrogen were detected by ELISA. Analysis of covariance was used to examine the effect of ER-ct polymorphisms on bone development. Results The absolute increase and percentage change of BGP were significantly higher in the supplemented group than in the control group （P〈0.05）. In the intervened group, The increase and percentage change of the total body and radio distal 1/3 BMD were higher in PP than in PP genotype （P〈0.05）, and the increase of BAP in Pp was also higher than PP in the same group （P〈0.05）. Conclusion PP genotype shows a better response to calcium supplementation than the other Pvull polymorphisms.

文摘To investigate the cembranoid diterpenes from the soft coral Sarcophyton sp. collected in the South China Sea. Repeatedly column chromatography was performed for the isolation and purification. The structures were elucidated on the basis of extensive spectral data （IR, MS, 1 D- and 2D-NMR） analysis by comparing with literature data. A new cembranoid diterpene namely sarcophyolide A （1）, together with 7a, 8β-dihydroxydeepoxysarcophine （2） were isolated from this species. The cembranoid diterpenes with 7-1actone could be chemotaxonomic markers of Sarcophyton sp.
文摘The effect of Moringa oleifera leaf powder supplementation on some physico-chemical and sensory properties of wheat bread was determined. Bread was prepared from varying proportions of 100%, 99%, 98%, 97%, 96% and 95% wheat flour supplemented with 0%, 1%, 2%, 3%, 4% and 5% Moringa oleifera leaf powder respectively. The bread samples were allowed to cool at ambient temperature (30℃± 1℃) and analysed for some physical properties, proximate composition, and sensory attributes. Moringa leaf powder addition significantly (p % to 3.28%), ash (1.10% to 1.65%), protein (9.07% to 13.97%), and ether extract (1.51% to 2.59%), while decreasing moisture content (35.20% to 27.65%). Moringa leaf powder supplementation also significantly (p cm3, 32.32 to 25.65 g, 7.00 to 5.83 cm and 4.70 to 2.65 cm3/g respectively, while the loaf weight increased from 169.20 to 185.86 g. There was a significant (p mg/100g and 0.02 to 3.27 mg/100g respectively, while Iron (Fe) and Cupper (Cu) contents decreased from 2.74 to 1.25 mg/100g and 2.26 to 0.03 mg/100g respectively. Sensory evaluation showed that although there was significant (p Moringa supplementation. This implies that despite the high nutrient content of Moringa oleifera powder, it is not a good substitute for wheat in bread production due to its physical characteristics and sensory attributes.

文摘The present experiment was conducted to determine the effects of Molasses-Urea Supplementation （MUS） on weight gain, ruminal fermentation and major microbial populations in sheep on a winter grazing regime in Inner Mongolia. Total 40 sheep, allowed free consumption of MUS after grazing, served as a treatment group, while 30 sheep, fed only by pasture grazing, served as a control group. Ruminal fermentation parameters, consisted of pH, Bacterial Crude Protein （BCP） and ammonia nitrogen （NH3-N） were measured. In addition, numbers of five symbiotic bacteria were investigated. The results showed as follows： the average daily weight gain, concentration of NH3-N and numbers of protozoa were significantly higher （p〈0.05） in the treatment group than those in the control group. Contrastingly, no significant difference was found in BCP concentration and pH between the two groups. At the end of the experiment, the populations of Selenomonas ruminantium, Anaerovibrio lipolytica, Fibrobacter succinogenes, Ruminococcus flaveciens and Ruminococcus albus in the treatment group were significantly higher than those of the control group （p〈0.05）. These results demonstrated that greater weight gain could be induced during winter in Inner Mongolia by improved nutritional status through promotion of microbial populations using urea and sugar.

文摘BACKGROUND：Alcoholic liver disease（ALD）is one of the main causes of liver disease worldwide.Although the pathogenesis of ALD has not yet been well elucidated,the oxidative metabolites of ethanol such as acetaldehyde and reactive oxygen species play a pivotal role in the clinical and pathological spectrum of the disease.This review summarizes the existing evidences on dietary supplements considered to have antioxidant,and/or anti-inflammatory properties,and their role in the management of ALD and the proposed mechanisms.DATA SOURCES：The present study reviewed all studies published in Pub Med,Science Direct and Scopus,from 1959 to2015,indicating the role of different dietary supplementation in attenuation of many pathophysiological processes involved in development and progression of ALD.Full-texts of citations were used except for those that were published in languages other than English.RESULTS：Significant progress has been made to understand the key events and molecular players for the onset and progression of ALD from both experimental and clinical studies;however,there is no successful treatment currently available.The present review discussed the role of a variety of dietary supplements（e.g.vitamin A,carotenoids,vitamins B3,C and E,in addition to antioxidants and anti-inflammatory agents）in treating ALD.It has been shown that supplementation with some carotenoids,vitamin B3,vitamin C,silymarin,curcumin,probiotics,zinc,S-adenosylmethionine and garlic may havepotential beneficial effects in animal models of ALD;however,the number of clinical studies is very limited.In addition,supplementation should be accompanied with alcohol cessation.CONCLUSIONS：Since oxidative stress and inflammation are involved in the pathogenesis of ALD,dietary supplements that can modulate these pathologies could be useful in the treatment of ALD.In addition to alcohol cessation,these supplements have shown beneficial effects on animal models of ALD.Clinical trials are needed to validate the beneficiary role of these supplements in patients with ALD.
