The effect of dried-ground Urtica dioica L. on microbiological characteristics of Turkish dry-fermented sausage (sucuk) were investigated. Dried-ground Urtica dioica L. was added to sucuk batters by the rate of 0%, 1%, 3% and 5%, and microbiological analysis were made on the 0, 3, 7, 10 and 14 days of ripening period.
According to the results, both the level of Urtica dioica L. and ripening time had a significant effects on the total aerobic mesophylic bacteria, lactic acid bacteria, Micrococcus/Staphylococcus, yeast-mould and Enterobacteriaceae counts (p<0.01). It was determined that the interactions ripening time × the levels of Urtica dioica L. had a significant effects on the counts of total aerobic mesophylic bacteria, lactic acid bacteria, Micrococcus/Staphylococcus, yeast-mould and Enterobacteriaceae (p<0.01). Enterobacteriaceae count were also found to be under the detectable level (<100 cfu/g) in sucuks (in day 14 of ripening) containing 3% and 5% Urtica dioica L. 相似文献
Transgenic 3.L2 T cells are stimulated by Hb(64-76)/I-Ek and are positively selected on I-Ek plus self-peptides. To this pool of self-peptides we have added a single, well-defined 3.L2 TCR antagonist (A72) in vivo. We find that mice expressing both the 3.L2 TCR and A72 have a minimal loss of T cells expressing the clonotypic TCR in the thymus and spleen. Importantly, the proliferative response of 3.L2 x A72 splenocytes is significantly reduced compared with splenocytes from 3.L2 mice. This reduced response can be attributed to peripheral antagonism. Thus we have identified a new class of self-ligands whose predominant effect is constitutive peripheral antagonism rather than negative selection. The net effect of these ligands is to avoid potential self-reactivity while maintaining as large a repertoire as possible. 相似文献
Climacterium is characterized by symptoms that occur as a result of the differentiation of hormonal equilibrium. It begins around the age of 40 and continues up to the age of 60. In this period cycles are usually anovulatory. This paper presents a case which may be diagnosed as abortus incompletus despite the patient being in menopause for five years previously. 相似文献
BACKGROUND: To examine the effect of endothelin-1 (ET-1) on spontaneous contractile activity and the effects of nimodipine and isradipine on ET-1-induced contractile responses in myometrial strips isolated from normal pregnant and preeclamptic women. MATERIAL AND METHODS:. Isolated myometrial strips were obtained from seven normal pregnant and seven preeclamptic women undergoing elective cesarean section and the strips were mounted in organ baths for recording of isometric tension. The effect of increasing concentration of ET-1 on spontaneous contractions and effects of increasing concentration of nimodipine and isradipine on ET-1-induced contractions were recorded. RESULTS: ET-1 dose-dependently (10(-11)-10(-8) M) increased the amplitude and frequency of spontaneous contractions in all myometrial strips obtained from normal pregnant and preeclamptic women. The increase in the amplitude of contractions in preeclamptic strips was significantly higher than that of normal strips. The increase in amplitude of contractions in normal and preeclamptic strips reached statistical significance beginning from the concentrations of 10(-9) M and 10(-11) M, respectively. ET-1 (10(-8) M) also increased the basal tone of all myometrial strips isolated from normal pregnant and preeclamptic women. When ET-1 (10(-8) M)-contracted myoinetrial strips were exposed to increasing concentrations of nimodipine (10(-6)-3x10(-5)M) and isradipine (10(-5)-3x10(-4) M), nimodipine and isradipine dose-dependently decreased the amplitude and frequency of contractions. CONCLUSIONS: The increase in contractile response with ET-1 was significantly higher in myometrial strips isolated from preeclamptic women compared to those of myometrial strips isolated from normal pregnant women. These increases in contractile response are at least in part mediated by dihydropyridine-sensitive calcium channels, since they were significantly reduced in the presence of increasing concentrations of nimodipine and isradipine. 相似文献
Loyalty to one's extended family, a well-known Japanese tradition, has broken down following World War II. Child rearing in Japan, therefore, has been changing gradually and clearly. Traditionally, child rearing was taught to young mothers by the grandmothers. However, recently young couples are no longer living with their parents. Therefore, there are no advisers nor consultants available at home for their child rearing. Commercialism has certainly invaded the field of child rearing, including too many guidebooks and even baby-sitting companies. Children's lives have become much more competitive, busy and unnatural in comparison with those of 20-30 years ago. This might be one cause of the increased incidence of bullying, school phobia and psychological disorders in children. 相似文献
We solve for the optimum signature sequence and power allocation policies that maximize the information-theoretic ergodic sum capacity of a code-division multiple-access (CDMA) system subject to fading. We show that at most N users may transmit at any given channel state, where N is the processing gain; and those users who are transmitting should be assigned orthogonal signature sequences. We also show that the power allocation policy that maximizes the capacity together with the choice of these signature sequences is single-user water-filling over sets of channel states that are favorable to each user. That is, the capacity maximizing signaling scheme is shown to dictate that the users allocate their powers and signature sequences in such a way that they always avoid interference from each other. 相似文献
