AIM: To inquire into a question of an overestimation of arterial involvement in patients with pancreatic cancer (PC). METHODS: radiology data were compared with the findings from 51 standard, 58 extended and 17 total pancreaticoduodenectomies; 9 distal resections with celiac artery (CA) excision; and 28 palliations for PC. The survival of 11 patients with controversial computed tomography (CT) and endoscopic ultrasound data with regard to arterial invasion, after r0/r1 procedures (false-positive CT results, Group A), was compared to survival after eight r2 resections (false-negative CT results, Group B) and after 12 bypass procedures for locally advanced cancer (true-positive CT results, Group C).rESULTS: In all of the cases in group A, operative exploration revealed no arterial invasion, which was predicted by CT. The one-year survival in Group A was 88.9%, and the two-year survival was 26.7%, with a median follow-up of 22 mo. One-year survival was not attained in groups B and C, with a significant difference in survival (P a-b = 0.0029, P b-c = 0.003).CONCLUSION: Arterial encasement on CT does not necessarily indicate arterial invasion. Whenever PC is considered unresectable, endoUS should be used. In patients with controversial CT an EUS data for peripan-creatic arteries involvement radical resection might be possible, providing survival benefits as compared to r2-resections or palliative surgery.

We present a study of the inclusive photon spectra from 5.9 million J/ψ decays collected with the KEDr detector at the vEPP-4M e＋e collider. We measure the branching fraction of radiative decay J/ψ→ηcγ, ηc width and mass. Our preliminary results are： M（ηc） = 2979.4± 1.5 ± 1.9 Mev/c^2, Г（ηc） = 27.8±5.1 ±3.3 Mev, B（Jψ→ηcγ） = （2.34±0.15±0.40）%.

Present article discusses the physiological mechanisms of the state employees adaptation during active training in temporary groups. It is suggested that adaptive mechanisms to adverse effects may be studied basing on the concept of functional isomorphism of the psychic and immune systems. Adaptive mechanisms were studied through the monitoring of the stress factors’ impact upon the law enforcement officers when training outside the places of permanent deployment. The specific purpose of present study was to evaluate the physiological indicators of the psychic, immune and endocrine systems dynamics at different stages of adaptation of the live organism to a stressful situation, hoping to get better insight into possible relations between psychic and immune domains. Through monitoring of the dynamics of the endocrine and immune responses to the psychic stimuli, it was possible to correlate the stages of the stress onset to the phases of specific immune reactions. Strong correlations between the parameters characterizing activation of the psychic and immune responses support the hypothesis of the presence of “strong cooperation” between psychic and immune domains. It supports earlier hypothesis that we are monitoring different manifestations of the functioning of a complex inseparable psycho-immune meta-system.

Juvenile myoclonic epilepsy (JME) is characterised by myoclonia during awakening, generalised tonic-clonic seizures, typical absences and usually presents for the first time at the age of 12 to 18 years old. This article describes the results of a clinical study into JME phenotypes in patients living in the Siberian Federal District. We have shown that the incidence of JME among males was lower than among females (1:1.9) and JME debut age for males was higher than in those women. Classical phenotype of JME (Type I) was dominant and more common in males compared to females—70.4% vs. 58.5%, respectively. The JME phenotype with worse prognosis in terms of achieving stable clinical remission (Type II) occurred 3.5 times more frequently among female patients compared to male (13.2% vs. 3.7% respectively). The findings resulting from this study give a deeper insight into the diagnosis and prognosis of this form of idiopathic generalised epilepsy in predisposed families.

研究表明,在诸多生产过程中可以优化输入的断裂能量,使加工能耗最小.以一个简单的中心断裂为例,当加截脉冲具有某种特定形态时,施加到样品上引发破裂的能量可以取一个显著的最小值.研究结果显示,优化各种与断裂有关的生产过程,使得能量消耗最小是可能的.这种优化的可能应用包括钻孔或岩石粉碎过程,此时能耗成本通常占生产成本的最大部分.上述方法可以预测钻孔或研磨机等的最优参数,从而大大降低生产成本.文章第二部分研究了接触作用条件下引发断裂的能量输入行为.考虑一个球型粒子冲击一个半空间靶的情形,接触导致的应力场可用赫兹解来估计.定义了断裂判据之后,即可确定引发断裂的球粒临界速度及相应的临界动能.该动能的大小依赖于加载的持续时间,并十分明显地存在一个最小值.据此可断定,存在一个动态冲击的能量最优模式.

宽带平衡放大器用的混合集成电路(HIC)在超高频范围内已广泛地用于各种收发机上,因为它能使我们在输入和输出端获得低电压驻波比、线性更好的相位-频率特性以及比单级放大器更大的动态范围。在宽带平衡放大器的研制中要解决的主要问题是选择晶体管的输入和输出端的匹配电路,用以提供均匀的振幅-频率性能和在宽带内使源和负载之间匹配。本文中我们讨论采用具有不同Q因子的短线定向耦合器(SDC)作为耦合器的微带平衡超高频放大器混合集成电路(HIC)的研究,并考虑到晶体管的稳定性。
