Acid–Base Parameters and Steroid Concentrations in Pre‐Ovulatory Follicles and Plasma of Lactating Dairy Cows with Spontaneous and Synchronized Oestrus or Follicular Cyst     

HA Hussein  Z Boryczko  H Bostedt 《Reproduction in domestic animals》2013,48(5):833-839

The study aimed to compare the acid–base balance and steroid concentrations between follicular fluids (FF) of pre‐ovulatory follicles derived from a spontaneous oestrus (SO), synchronized or induced oestrus (IO) and follicular cysts (CYS) and between FF and blood in dairy cows. Forty‐two dairy cows were included in this study. The animals were allocated to three groups: SO (n = 23); IO (n = 11) using GnRH at day 0 and day 9 and PGF₂α at day 7; and animals with CYS (n = 10). The follicular fluids (FF) were aspirated from the cyst/pre‐ovulatory follicles (? ≥ 15 mm) after SO and after second GnRH dose in IO by transvaginal ultrasound‐guided ovum pick‐up technique. Blood samples (BL) were collected in heparinized vacutainer tubes. The oxygen tension (pO2) in FF of IO was higher (p < 0.05) than in SO and CYS groups. There were negative correlations (p < 0.001, r = ?0.89) between FF and blood pO2. The carbon dioxide tension (pCO2) and lactate level in FF of CYS group were higher (p < 0.05) than in SO and IO groups. There were negative correlations (p < 0.01, r = ?0.73) between blood and FF pO2. Oestradiol‐17β concentration in pre‐ovulatory follicles and plasma of the SO group was higher (p < 0.001) than in IO and CYS groups. Progesterone concentration in pre‐ovulatory follicles and plasma of the SO and IO groups was lower (p < 0.01) than in CYS group. Plasma androstenedione concentration in SO and IO groups was higher (p < 0.05) than in CYS group. In conclusion, acid–base parameters, E2 and P4 levels in the follicular fluid of both IO and CYS groups were deviated greatly from the physiological level (disturbances of intrafollicular/intracystic environment), which may affect the quality of both the oocyte and the granulosa cells.  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

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   

The influence of diel period on fish assemblage in the unstructured littoral of reservoirs     

M. ŘÍHA  J. KUBEČKA  M. PRCHALOVÁ  T. MRKVIČKA  M. ČECH  V. DRAŠTÍK  J. FROUZOVÁ  E. HOHAUSOVÁ  T. JŮZA  M. KRATOCHVÍL  J. PETERKA  M. TUŠER  M. VAŠEK 《Fisheries Management and Ecology》2011,18(4):339-347

Abstract Diel changes in littoral fish assemblage were studied in four reservoirs in the Czech Republic (Central Europe). The sampling was performed by beach seining in an unstructured littoral zone. Perch, Perca fluviatilis L., roach, Rutilus rutilus (L.), bream, Abramis brama (L.), carp, Cyprinus carpio L., ruffe, Gymnocephalus cernua (L.), pikeperch, Sander lucioperca (L.), eel, Anguilla anguilla (L.) and A. brama × R. rutilus hybrids exhibited higher densities at night. Only bleak, Alburnus alburnus (L.) exhibited higher densities during the day. The number of species was higher in night hauls, and mean body size of roach and bleak was also higher at night. Diel changes in fish densities resulted in the change in species composition between day and night. The study has implication for the sampling design to assess littoral fish assemblages using beach seine netting and recommends night sampling for a representative assessment or sampling during both diel periods for a robust assessment.  相似文献

对高pH养殖水体中"黄海1号"中国对虾(Fenneropenaeus chinensis)群体和野生群体的存活率,血清中的溶菌酶(LSZ)、酚氧化酶(PO)、超氧化物歧化酶(SOD)、碱性磷酸酶(AKP)及酸性磷酸酶(ACP)活力变化进行了测定.经高pH胁迫72 h后检测发现,在pH8.2～8.6,"黄海1号"和野生群体存活率均高于90%,两群体机体表现出一定的应激能力;在pH8.8～9.0时,"黄海1号"及野生群体死亡率都急剧增加,几种免疫相关酶类较在pH 8.6时都有较高幅度的变化,"黄海1号"的死亡率及酶突变程度均小于野生群体;在pH 9.2时,2群体的死亡率及体内的几种免疫相关酶活性变化幅度继续增大,但2群体间差异减弱;在pH 9.4时,两群体中国对虾全部死亡.比较发现,当海水pH在一定的范围内升高时,"黄海1号"免疫能力要高于野生群体.  相似文献
