Abstract

The aim of review. To discuss issues of diagnostics of choledocholithiasis at the present time.Original positions. The relevance of early recognition of choledocholithiasis is determined by high frequency at patients with cholelithiasis and risk of development of life-threatening complications. Diagnostics of choledocholithiasis is based on clinical data, laboratory and instrumental tests. Instrumental methods of investigation differ by their information value and invasiveness. So, it is important to define prognostic criteria (clinical, biochemical and ultrasound), determining necessity of additional more invasive and expensive investigation of bile ducts. However estimation of diagnostic criteria suggested by different authors and their threshold values is ambiguous. Discordant opinions frequently lead both to underestimation of the role of clinical and laboratory data, and to unjustified application of invasive diagnostic methods.Conclusion. Further studies are necessary to develop more rational and objective systems of diagnostics of choledocholithiasis.

Abstract

We review the status of the Lake Baikal Neutrino Experiment. The Neutrino Telescope NT200 has been operating since 1998 and has been upgraded to the 10 Mton detector NT200+ in 2005. We present selected astroparticle physics results from long-term operation of NT200. Also discussed are activities towards acoustic detection of UHE-energy neutrinos, and results of associated science activities. Preparation towards a km3-scale (Gigaton volume) detector in Lake Baikal is currently a central activity. As an important milestone, a km3-prototype string, based on completely new technology, has been installed and is operating together with NT200+ since April, 2008., Comment: 8 pages, 12 figures; presented at VLVNT08 (Very Large Volume Neutrino Telescope) Workshop, Toulon, France, April, 2008; to appear in NIM-A

Abstract

A project of the NT1000 deep-water neutrino telescope with an effective volume of ∼1 km3 is currently being developed by the BAIKAL collaboration. The telescope will be located in Lake Baikal in close vicinity of the NT200+ detector, which is currently in operation. The telescope will be composed of 12 clusters with 8 similar strings of optical modules in each (each string has two sections of the NT1000 optical modules). The section of the NT1000 optical modules has been developed using higher-efficiency photomultiplier tubes and state-of-the-art electronics. The field tests of the experimental string consisting of two sections with six optical modules in each have been performed. The results of these investigations are used in the project of the NT1000 neutrino telescope and in the hydrological study of Lake Baikal.

As an important milestone, a km3-prototype string comprising 6 optical modules and based on a completely new technology, has been installed and was put into operation together with NT200+ in April, 2008. An upgraded version of the prototype string, which comprises 12 optical modules, was put into operation in April 2009. We also present new results from the long-term operation of NT200, including an improved limit on the diffuse astrophysical neutrino flux.

Abstract

We review the status of the Baikal Neutrino Telescope, which has recently been upgraded to the 5 Mton detector NT200+. We present results on searches for upward going atmospheric neutrinos and relativistic magnetic monopoles, obtained from 1998-2002 with the predecessor detector NT200. A search for very high energy neutrinos yields an upper limit on the extraterrestrial diffuse neutrino flux for 20 TeV < E < 50 PeV. We describe the strategy of upgrading NT200 to NT200+ and creating a detector on the Gigaton (km3) scale at lake Baikal. R&D activities on that next stage detector have been started.

Abstract

High-frequency noise of Lake Baikal is investigated using a submersible self-contained instrument to determine the noise background for the acoustic detection of superhigh-energy neutrinos. It is found that, under stationary and uniform meteorological conditions, the integral noise power in the frequency band 1–50 kHz is virtually independent of depth and is 10–200 mPa or more, depending on the specific conditions. The noise itself contains multiple short pulses of different amplitudes and shapes.

Abstract

We review the present status of the Baikal Neutrino Experiment. On April 9th, 2005 the 10 Mton scale detector NT200+ was put into operation in Lake Baikal. We describe the configuration and physics potential of this detector. Selected results obtained during 1998-2002 with the neutrino telescope NT200 are presented.

Abstract

We review the ongoing work of the Baikal Collaboration on acoustic detection of super high energy neutrinos. Some results of the study of high frequency acoustic noise in Lake Baikal are presented. A lot of short impulses with different amplitudes and shapes were detected, which should be considered as a background for acoustic neutrino detection. However, most of the short impulses appear to be due to noise sound waves interference and can be eliminated by a correlation analysis. Only a few detected bipolar impulses probably were produced by quasi local sources.

Abstract

We present the results of a search for high energy extraterrestrial neutrinos with the Baikal underwater Cherenkov detector NT200, based on data taken in 1998 - 2002. Upper limits on the diffuse fluxes of $\nu_e+\nu_{\mu}+\nu_{\tau}$, predicted by several models of AGN-like neutrino sources, are derived. For an $E^{-2}$ behavior of the neutrino spectrum, our limit is $E^2 \Phi_{\nu}(E), Comment: 19 pages, 23 figures, submitted to Astroparticle Physics

Abstract

The article is based on an analysis of observation of 853 patients with complicated forms of cholelithiasis. The average age of patients was 73.5 years, two thirds of them had critical coexistent diseases. The system of treatment proposed by the authors allowed achievement of good results (lethality is less than 5%) while the methods of treatment generally accepted in surgical practice is followed by higher lethality achieving 40%. The work analyzes errors and complications of endoscopic decompressing operations and gives recommendations for their prevention.
