In this research project, we measured and analyzed the spatial distribution of neutron beam Bragg diffracted from the front- and back-faces of thin Si single crystal undergoing on ultrasound excitation. For the perfect crystal, it is shown that when the acoustic wave amplitude is increased, the front-face peak position remains unchanged and its value grows linearly. the values of ultrasound wave amplitude were determined. the back-face peak becomes asymmetric and tends to disappear. New types of Pendellosung fringes in the center of the diffraction profiles were observed at the first time. It is supposed that in the perfect crystal this effect may be due to the appearance of the new “sonic” extinction length, depending on the amplitude of the ultrasonic wave. thus, it leads to the new interference interactions between neutron wave and ultrasonic phonons. It is established that within the framework of the dynamical theory of the neutron scattering, some asymptotic models valid for the case of Laue geometry as well as kato’s quasi-classical approximation can be applied in the case of Bragg geometry also. Good agreement between experimental data and the theory has been obtained.

研究了青花菜采收预冷后置于20℃下早期乙烯生成特性和乙烯受体基因的表达。结果表明，乙烯生成速率在茎切面第一层0-6h明显上升，在小花中明显下降。ACC合成酶活性与乙烯生成速率的变化一致。ACC含量在各组织中先上升后下降，以小花中最低。MACC含量以花头基部最低，小花中较高，变化平稳。各组织中ACC氧化酶活性在0-12h呈增加趋势，但小花明显高于茎组织，与乙烯生成速率变化不一致。Northern杂交分析表明，茎切面第一层的BO-ACS1和BO-ACO2的mRNA水平在0h时高于小花，12h时低于0h。小花中BO-ACS1 mRNA在12h增加不明显，BO-ACO2 mRNA增加明显。BO-EtR1、BO-ERS和BO-EtR2在茎切面第一层，BO-ERS在小花中，转录物12h时均比0h有不同程度的增加，BO-EtR2 mRNA仅在茎组织中检测到。

After the first observation of the immunosuppressive effects of ultraviolet(UV) irradiation was reported in 1974, therapeutic modification of immune responses by UV irradiation began to be investigated in the context immunization. UV-induced immunosuppression is via the action of regulatory t cells(tregs). Antigen-specific tregs were induced by high-dose UV-B irradiation before antigen immunization in many studies, as it was considered that functional alteration and/or modulation of antigen-presenting cells by UV irradiation was required for the induction of antigen-specific immunosuppression. However, it is also reported that UV irradiation after immunization induces antigen-specific tregs. UV-induced tregs are also dominantly transferable, with interleukin-10 being important for UV-induced immunosuppression. Currently, various possible mechanisms involving treg phenotype and cytokine profile have been suggested. UV irradiation accompanied by alloantigen immunization induces alloantigen-specific transferable tregs, which have potential therapeutic applications in the transplantation field. Here we review the current status of UV-induced antigen-specific immunosuppression on the 40th anniversary of its discovery.

BACKGROUND: Although non-thyroidal illness syndrome(NtIS) is considered a negative prognostic factor, the alterations in free triiodothyronine(f t3) levels in trauma patients requiring massive transfusion have not been ***: A prospective observational study comparing 2 groups of trauma patients was conducted. Group M comprised trauma patients requiring massive transfusions(>10 units of packed red blood cells) within 24 hours of emergency admission. Group C comprised patients with an injury severity score >9 but not requiring massive transfusions. Levels of f t3, free thyroxine(f t4), and thyroidstimulating hormone(tSH) were evaluated on admission and on days 1, 2, and 7 after admission. the clinical backgrounds and variables measured including total transfusion amounts were compared and the inter-group prognosis was evaluated. Results are presented as mean±standard ***: Nineteen patients were enrolled in each group. In both groups, 32 were men, and the mean age was 50±24 years. In group C one patient died from respiratory failure. the initial f t3 levels in group M(1.95±0.37 pg/m L) were signifi cantly lower than those in group C(2.49±0.72 pg/m L; Ptil 1 week after admission. Initial inter-group f t4 and tSH levels were not significantly different. tSH levels at 1 week(1.99±1.64 μIU/m L) were higher than at admission(1.48±0.5 μIU/m L) in group C(Ptypical NtIS was observed in trauma patients requiring massive transfusions. When initial resuscitation achieved circulatory stabilization, prognosis was not strongly associated with NtIS.

Cytogenetic analysis was performed on a specimen from a pulmonary metastasis of clear cell sarcoma originated on the right ankle of a 53- year-old Japanese woman. It revealed neartriploid with several numerical changes in cluding abnormalities in the copy number of chromosomes 7, 8, and 22, and structural abnormalities of chromosome 22 and others. this is a minor case which showed the multiple abnormalities of chromosomes in the absence of a t (12;22) translocation.
