本文回顾了在重离子引起的深度非弹性反应中,N/Z完全弛豫的实验结果。报道了关于非常不对称反应体系40Ar（E_实=263 MeV）+238U,实验测得的反应产物之同位素分布。反应产物的鉴定是通过两个独立的飞行时间测量和两个（△E-E）测量的信息相结合,进行质量和电荷的双重鉴定来实现的。为了解释40Ar+238U以及另外四个非常不对称反应体系(40Ar+197Au,32S+238U,63Cu+232Th和40Ar+232Th)的实验所得同位素分布,本文提出了一个简单的经典模型,计算结果与所有实验的符合是十分令人满意的。

Protein-Repairing Methionine Sulfox.de Reductases in Photosynthetic Organisms： Gene Organization, Reduction Mechanisms, and Physiological Roles

引用

Molecular Plant 2009年第2期2卷 202-217页

作者： Lionel tarrago Edith Laugier Pascal Rey CEA DSV IBEB Laboratoire d'Ecophysiologie Moleculaire des Plantes B~timent 161 SBVME CEA-Cadarache 13108 Saint-Paul-lez-Durance Cedex France

Methionine ox.dation to methionine sulfox.de （MetSO） is reversed by two types of methionine sulfox.de reducrases （MSRs）, A and B, specific to the S- and R-diastereomers of MetSO, respectively. MSR genes are found in most organisms from bacteria to human. In the current review, we first compare the organization of the MSR gene families in photosynthetic organisms from cyanobacteria to higher plants. The analysis reveals that MSRs constitute complex.families in higher plants, bryophytes, and algae compared to cyanobacteria and all non-photosynthetic organisms. We also perform a classification, based on gene number and structure, position of redox.active cysteines and predicted sub-cellular localization. The various catalytic mechanisms and potential physiological electron donors involved in the regeneration of MSR activity are then de- scribed. Data available from higher plants reveal that MSRs fulfill an essential physiological function during environmental constraints through a role in protein repair and in protection against ox.dative damage. Taking into consideration the ex. pression patterns of MSR genes in plants and the known roles of these genes in non-photosynthetic cells, other functions of MSRs are discussed during specific developmental stages and ageing in photosynthetic organisms.

Transanal endoscopic surgery in rectal cancer

World Journal of Gastroenterology 2014年第33期20卷 11538-11545页

Total mesorectal ex.ision(TME) is the standard treatment for rectal cancer, but complications are frequent and rates of morbidity, mortality and genitourinary alterations are high. Transanal endoscopic microsurgery(TEM) allows preservation of the anal sphincters and, via its vision system through a rectoscope, allows access to rectal tumors located as far as 20 cm from the anal verge. The capacity of local surgery to cure rectal cancer depends on the risk of lymph node invasion. This means that correct preoperative staging of the rectal tumor is necessary. Currently, local surgery is indicated for rectal adenomas and adenocarcinomas invading the submucosa, but not beyond(T1). Here we describe the standard technique for TEM, the different types of equipment used, and the technical limitations of this approach. TEM to remove rectal adenoma should be performed in the same way as if the lesion were an adenocarcinoma, due to the high percentageof infiltrating adenocarcinomas in these lesions. In spite of the generally good results with T1, some authors have published surprisingly high recurrence rates; this is due to the ex.stence of two types of lesions, tumors with good and poor prognosis, divided according to histological and surgical factors. The standard treatment for rectal adenocarcinoma T2N0M0 is TME without adjuvant therapy. In this type of adenocarcinoma, local surgery obtains the best results when complete pathological response has been achieved with previous chemoradiotherapy. The results with chemoradiotherapy and TEM are encouraging, but the scientific evidence remains limited at present.

Sleep Deprivation Affects Working Memory in Low but Not in High Complex.ty for the N-Back Test

Sleep clearly influences learning and memory since sleep deprivation and stress impairs both cognitive processes. Working memory is an essential cognitive process and refers to a short-term holding of incoming information required to update the long-term mnemonic storage and to manipulate new elements in order to solve problems and make decisions. Nevertheless, the influence of sleep deprivation on working memory has scarcely been studied. In this study we evaluated working memory using the N-back test after increasing periods of wakefulness. Healthy young males were kept awake for 36 hours and the two N-back tasks with low (1-Back) and high (3-Back) levels of complex.ty were applied every 6 hours. Additionally, salivary cortisol was determined along the study. Unlike the control non-deprived participants, the sleep deprived volunteers showed a significant decrease in their efficiency to solve the 1-Back task after 24 hours of sleep deprivation. However, no differences were observed after 30 and 36 hours of sleep deprivation. Concerning the 3-Back task no differences were observed after sleep deprivation. Regarding reaction time, the deprived group manifested slower responses for the 1-Back task and for the 3-Back task after 30 hours and 36 hours of sleep deprivation, respectively. Cortisol levels presented the normal daily oscillation and no differences were observed between groups. This data suggests that sleep deprivation affects basal states of attention instead of working memory while performing simple tasks. The impact of sleep deprivation on the cognitive performance depends on the moment of day when the task is applied and the complex.ty of the tests used to assess these mnemonic skills.
