OBJECTIVE: To assess the effects of socio-economic status (SES) on BMI, waist:hip ratio (WHR) and waist circumference (WC) in a group of Iranian women. METHODS: A cross-sectional study was conducted on 888 women in Sistan and Baluchestan Province. SES was measured using level of education. In addition, parity, marital status and physical activity were assessed. Standardized measurements were taken, BMI and WHR were calculated. RESULTS: Low education level was a strong determinant of overweight and obesity among Iranian women. After controlling for age, women with higher education level had significantly lower BMI, WC and parity. Multiple linear regression analysis found a significant negative association of BMI and WC with education level and a significant positive association of BMI and WC with parity. Significant factors associated with obesity by a logistic regression model were education level (OR for university graduates v. illiterate or low literacy levels: 1.00 v. 3.70; P = 0.01), living with spouse (OR for married v. single subjects: 1.00 v. 0.15; P = 0.05), parity (OR for more than five v. less than two pregnancies: 1.00 v. 0.34; P = 0.03) and WC (OR for < 0.88 cm v. > or = 0.88 cm: 1.00 v. 11.20; P = 0.001). CONCLUSION: The present study revealed that educational level, multiple pregnancies, marital status and lack of exercise are some possible explanations for the obesity among Sistan and Baluchestan women.  相似文献   

吸收剂量、贮藏时间及贮藏温度对辐照牛肉中2-十二烷基环丁酮的影响   总被引：2，自引：1，他引：1  

张海伟  王锋  周洪杰  张庆芳  哈益明 《核农学报》2008,22(6):816-819

分析了辐照牛肉中辐解产物2-十二烷基环丁酮在不同的吸收剂量(0.5~10.0kGy)、贮藏时间(0-40d)及贮藏温度(-20℃~4℃)下的变化规律。采用硅胶层析柱-气相色谱/质谱联用技术萃取分离并检测。结果表明,2-十二烷基环丁酮的浓度与吸收剂量呈线性正相关,随着贮藏时间延长其含量减少,贮藏温度对其没有显著影响。利用2-十二烷基环丁酮可鉴定牛肉是否经过辐照,在已知贮藏温度和时间的条件下,可评估辐照牛肉的大约吸收剂量范围。  相似文献

1/25 translocations in Blonde d'Aquitaine cattle in New Zealand     

Pearce PD  Ansari HA  Maher DW  Amarante MR  Monro TL  Hendrikse WL 《New Zealand veterinary journal》1997,45(2):69-71

A Robertsonian centric fusion between chromosomes 1 and 25 in Blonde d'Aquitaine cattle in New Zealand is reported. This fused chromosome is the same as the widely reported 1/29 translocation chromosome with the difference in the numbering arising from inconsistencies in the G and R-banded cattle karyotypes of the International System for Cytogenetic Nomenclature of Domestic Animals, 1989.  相似文献

Expression of natural killer cell stimulatory receptor NKG2D and its ligand MICA in Tibetan patients with gastric cancer at Qinghai plateau     

YANG Sheng-xi  ZHANG Xiao-yan  LUTong-de  HA Xiao-qin  WANG Hai-yan  GENG Pai-li 《园艺学报》2008,24(5):1002-1006

AIM: To investigate the expression of natural killer cell stimulation receptor D(NKG2D) in peripheral blood and the expression of major histocompatibility complex class I chain-related protein A(MICA) on the gastric carcinoma tissue and the neighboring non-cancerous tissue in Tibetan patients with gastric cancer at Qinghai plateau. METHODS: Samples of 33 patients and 20 healthy persons were collected to detect NKG2D in peripheral blood by Flow cytometry analysis. The expressions of MICA in part of the correspondent tissues were examined by RT-PCR and immunohistochemistry.RESULTS: The expression of NKG2D in the plateau of Tibetan patients with gastric cancer group (13.47 ±5.26)% was significantly lower than that in healthy groups (32.62±10.08)%. The mRNA level of MICA in gastric cancer was significantly higher than that in neighboring non-cancerous tissue (P<0.05). The expressions of MICA proteins showed a significant difference between the neighboring non-cancerous tissue (21.21%, 7/33) and the gastric carcinoma tissue (78.79%, 26/33), between the high differentiation (60.00%, 3/5) and the moderate (72.73%, 8/11), low differentiation (88.24%, 15/17). The expressions of MICA were not correlated with tumor size, sex, age, lymph node metastasis of the patients (P>0.05). Spearman rank correlation displayed that the expressions of MICA mRNA were positively correlated with the MICA protein level (r=0.903, P<0.01).CONCLUSION: The immune escape in Tibetan patients with gastric cancer at Qinghai plateau probably relates to the down-regulation of NKG2D and the up-regulation of its ligand MICA. The activity of NK cells and the anti-cancer cellular immunity level are descending in the plateau of Tibetan patients with gastric cancer. The decrease in the receptor NKG2D is a reason for the activity of NK cell descending.  相似文献   

Unrecognized diversity in New Guinean crayfish species (Decapoda,Parastacidae): The evidence from molecular data          下载免费PDF全文

Martin BLÁHA  Jiří PATOKA  Pavel KOZÁK  Antonín KOUBA 《Integrative zoology》2016,11(6):457-468

The phylogenetic relationships among imported ornamental crayfish belonging to the genus Cherax were inferred from a combined dataset of 3 mitochondrial genes (COI, 16S and 12S) and by comparison with available GenBank sequences of 14 Cherax species. Furthermore, the concordance of previously described species obtained from a wholesaler (Cherax boesemani, C. holthuisi and C. peknyi) with available GenBank sequences was verified based on COI with special respect to comparison with sequences assigned as Cherax species. Recently described species C. gherardiae, C. pulcher and C. subterigneus belong to the northern group of Cherax species. Comparison and analysis with other GenBank COI sequences show previously unreported diversity of New Guinean species, suggesting 5 putative new species. Surprisingly, species assigned to the subgenus Astaconephrops do not form a monophyletic clade; this subgenus should be reappraised relative to the purported typical morphological characteristic of the uncalcified patch on male chelae. Increasing importation of crayfish underscores the importance of accurate species identification. Use of basic molecular methods is a necessary requisite for documenting occurrence, abundance and population trends of target species. Consequently, it helps to support eventual conservation decision‐making by stakeholders.  相似文献   

Adventitious rooting in shoot cuttings of Azadirachta indica and Pongamia pinnata     

Palanisamy  K.  Ansari  S. A.  Kumar  Pramod  Gupta  B. N. 《New Forests》1998,16(1):81-88

Adventitious rooting in shoot cuttings of neem (Azadirachta indica) and karanj (Pongamia pinnata) was investigated in different seasons. The influence of auxins and B-vitamins (neem only) was evaluated. Maximum rhizogenesis coincided with the emergence of new sprouts i.e. February (neem) and March (karanj). Considering both rooting percentage and root biomass, IBA was the most effective auxin tested. Compared to auxin free controls, IBA (1000 ppm in neem and 800 ppm in karanj) significantly increased adventitious rooting percentage (80 to 100 % respectively), the numbers of roots and root biomass for both species. In neem, B-vitamin treatment yielded 40–50% rooting for cuttings. This was significantly greater than rooting for controls but equivalent to IAA treatments. In neem, some of the cuttings treated with 2000–3000 ppm IBA had well developed root systems without any sprouts. In karanj, all auxin treatments promoted sprouting. The level of total soluble sugars in the rooting zone of neem and karanj was higher in non-rooted than rooted cuttings.  相似文献   

Effect of Gibberellic Acid Spray during Ontogeny of Mustard on Growth, Nutrient Uptake and Yield Characteristics   总被引：2，自引：0，他引：2  

N. A. Khan  H. R. Ansari  Samiullah 《Journal of Agronomy and Crop Science》1998,181(1):61-63

In a field trial conducted during 1993–1994, mustard ( Brassica juncea L. Czern & Coss.) cv. Varuna was sprayed with either deionised water or 10⁻⁵ M GA₃ at 40 (vegetative stage), 60 (flowering stage) or 80 (pod fill stage) days after sowing (DAS) to select the suitable growth stage for spray for augmenting productivity of the crop. Shoot length per plant, leaf number per plant, leaf area per plant, dry weight per plant and leaf area index and accumulation of N, P and K were recorded at 100 DAS. Pods per plant, seeds per pod, 1000 seed weight, seed yield, biological yield, harvest index and seed yield merit were computed at harvest. Growth, NPK accumulation and yield were maximal when spraying was done at 40 DAS. However, spraying at 40 and 60 DAS gave at par values for most of the growth and yield parameters. It was also noted that there was a significant difference in spray treatment at different growth stages only when G A, was sprayed and not when water was sprayed.  相似文献
