Technical Problems of Splenectomy in Hematological Diseases

The article focuses on the technical aspects of splenectomy (SE) in 1628 patients using two main techniques: laparoscopy (885 SEs) and laparotomy (743 SEs), with a description of various factors that influence the invasiveness and the success of the surgery. The fact is that in addition to the shape and size of an enlarged spleen, the technical complexity of the SE, especially in laparoscopic access depends on the following factors: perisplenitis, close presentation and fusion of the tail of the pancreas to the spleen, tumor infiltration of splenic vascular pedicle, branchy type of its structure, visceral obesity, compression of the splenic pedicle with enlarged and united lymph nodes. In most cases (60 %), there is a combination of several risk factors, thus making the surgery even more difficult. The indications for splenectomy, as well as its influence on the course of the main hematological disease are not considered in this paper

Biopsy of Lungs and Pleura in Hematologic Center

Background & Aims. Morphological, immunohistochemical, immunophenotypic, cytogenetic, molecular and genetic and other examinations of tissues affected by oncohematological diseases are obligatory. The aim of this paper is to evaluate findings of lung and pleura biopsies in different medical conditions using two basic techniques: thoracoscopy and diagnostic thoracotomy. Methods. Results of morphological examination of lung lesions in patients hospitalized in the Hematology Research Center under the Ministry of Health of the Russian Federation are presented. From 2004 till 2014, 76 biopsies of lung and/or parietal pleura were performed in 73 patients aged 19–77 years via thoracoscopic (48) and/or thoracotomic (28) approach. Results. No thoracoscopy- and thoracotomy-related complications were observed. Bioptate examinations proved to be informative in 66 (86.7%) patients. Lung lesions were most common in lymphoproliferative diseases. Lung involvement in cancer or metastases was twice as common as it has been expected before the biopsy. On the contrary, expected tuberculosis nature of lung lesions in 5 patients was confirmed only in 2 of them. In 18 cases (23.7 %), the cause of lung lesion was other than the expected one, and appropriate adjustments of the therapy were made. Conclusion. New less invasive methods of biopsy combined with complex laboratory diagnosing comply with current requirements and permit making a correct diagnosis of a pathological process located in lungs

The unique biosynthetic route from Lupinus Beta-conglutin gene to blad

Background: During seed germination, b-conglutin undergoes a major cycle of limited proteolysis in which many of its constituent subunits are processed into a 20 kDa polypeptide termed blad. Blad is the main component of a glycooligomer, accumulating exclusively in the cotyledons of Lupinus species, between days 4 and 12 after the onset of germination. Principal Findings: The sequence of the gene encoding b-conglutin precursor (1791 nucleotides) is reported. This gene, which shares 44 to 57% similarity and 20 to 37% identity with other vicilin-like protein genes, includes several features in common with these globulins, but also specific hallmarks. Most notable is the presence of an ubiquitin interacting motif (UIM), which possibly links the unique catabolic route of b-conglutin to the ubiquitin/proteasome proteolytic pathway. Significance: Blad forms through a unique route from and is a stable intermediary product of its precursor, b-conglutin, the major Lupinus seed storage protein. It is composed of 173 amino acid residues, is encoded by an intron-containing, internal fragment of the gene that codes for b-conglutin precursor (nucleotides 394 to 913) and exhibits an isoelectric point of 9.6 and a molecular mass of 20,404.85 Da. Consistent with its role as a storage protein, blad contains an extremely high proportion of the nitrogen-rich amino acidsinfo:eu-repo/semantics/publishedVersio

The ATLAS experiment at the CERN Large Hadron Collider: a description of the detector configuration for Run 3

Abstract The ATLAS detector is installed in its experimental cavern at Point 1 of the CERN Large Hadron Collider. During Run 2 of the LHC, a luminosity of  ℒ = 2 × 1034 cm-2 s-1 was routinely achieved at the start of fills, twice the design luminosity. For Run 3, accelerator improvements, notably luminosity levelling, allow sustained running at an instantaneous luminosity of  ℒ = 2 × 1034 cm-2 s-1, with an average of up to 60 interactions per bunch crossing. The ATLAS detector has been upgraded to recover Run 1 single-lepton trigger thresholds while operating comfortably under Run 3 sustained pileup conditions. A fourth pixel layer 3.3 cm from the beam axis was added before Run 2 to improve vertex reconstruction and b-tagging performance. New Liquid Argon Calorimeter digital trigger electronics, with corresponding upgrades to the Trigger and Data Acquisition system, take advantage of a factor of 10 finer granularity to improve triggering on electrons, photons, taus, and hadronic signatures through increased pileup rejection. The inner muon endcap wheels were replaced by New Small Wheels with Micromegas and small-strip Thin Gap Chamber detectors, providing both precision tracking and Level-1 Muon trigger functionality. Trigger coverage of the inner barrel muon layer near one endcap region was augmented with modules integrating new thin-gap resistive plate chambers and smaller-diameter drift-tube chambers. Tile Calorimeter scintillation counters were added to improve electron energy resolution and background rejection. Upgrades to Minimum Bias Trigger Scintillators and Forward Detectors improve luminosity monitoring and enable total proton-proton cross section, diffractive physics, and heavy ion measurements. These upgrades are all compatible with operation in the much harsher environment anticipated after the High-Luminosity upgrade of the LHC and are the first steps towards preparing ATLAS for the High-Luminosity upgrade of the LHC. This paper describes the Run 3 configuration of the ATLAS detector.</jats:p
