Pure Red Cell Aplasia with M-Gradient: A Literature Review and Clinical Experience
Background. Pure red cell aplasia (PRCA) is a rare syndrome characterized by a decrease of erythroid progenitor cell count in the bone marrow. M-gradient with both a light and a heavy chain types in PRCA patients is a rare phenomenon which is considered to be a specific form of the disease.
Aim. To review a clinical presentation, diagnostic capabilities, and treatment outcomes of PRCA with M-gradient.
Materials & Methods. The analysis included 10 patients. The most effective empirically established treatment program was 200β400 g of cyclophosphamide 2β3 times a week to a total dose of 6β10 g and loading courses of 100β120 mg of oral and 180β240 mg of intravenous prednisone daily within 5 days. On the 6th day prednisone injections were discontinued, and from the 7th day the oral dose of prednisone was gradually reduced to permanent discontinuation in 2β3 days. This treatment course was repeated 1β3 times at intervals of a week. Targeted enzyme immunoassay of M-gradient was performed in 4 patients in order to determine whether M-gradient is the sum of two antibody types, i.e. erythrokaryocyte antibodies and secondary anti-idiotype antibodies against primary antibodies.
Results. The total of 6 out of 10 PRCA patients reached complete remission within the period from 9 months to 22 years of follow-up, in 4 patients no remission was achieved. M-gradient contained IgG (n = 9) and IgA (n = 1) oligoclones. In typing it consisted of IgGΞ» (n = 4), IgGΞΊ (n = 5) and IgAΞΊ (n = 1). M-gradient enzyme immunoassay showed no primary and secondary anti-idiotype antibodies.
Conclusion. The obtained results allow to regard gammopathy in PRCA as an effect of oligoclonal hyper-immunoglobulin without any pathogenetic connection between M-gradient and PRCA

This paper describes the technique used to create and maintain the Active Faults of Eurasia Database (AFED) based on the uniform format that ensures integrating the materials accumulated by many researchers, incluΒding the authors of the AFED. The AFED includes the data on more than 20 thousand objects: faults, fault zones and associated structural forms that show the signs of latest displacements in the Late Pleistocene and Holocene. The geographical coordinates are given for each object. The AFED scale is 1:500000; the demonstration scale is 1:1000000. For each object, the AFED shows two kinds of characteristics: justification attributes, and estimated attributes. The justification attributes inform the AFED user about an object: the objectβs name; morphology; kinematics; the amplitudes of displacement for different periods of time; displacement rates estimated from the amplitudes; the age of the latest recorded signs of activity, seismicity and paleoseismicity; the relationship of the given objects with the parameters of crustal earthquakes; etc. The sources of information are listed in the AFED appendix. The estimated attributes are represented by the system of indices reflecting the fault kinematics according to the classification of the faults by types, as accepted in structural geology, and includes three ranks of the Late Quaternary movements and four degrees of reliability of identifying the structures as active ones. With reference to the indices, the objects can be compared with each other, considering any of the attributes, or with any other digitized information. The comparison can be performed by any GIS software. The AFED is an efficient tool for obtaining the information on the faults and solving general problems, such as thematic mapping, determining the parameters of modern geodynamic processes, estimaΒting seismic and other geodynamic hazards, identifying the tectonic development trends in the PlioceneβQuaternary stage of the Earth's development, etc. The Active Faults of Eurasia Database is created in the format providing for inputs of new information, as well the database updating and revision.ΠΡΠ΅Π΄ΡΡΠ°Π²Π»ΡΠ΅ΡΡΡ ΠΌΠ΅ΡΠΎΠ΄ΠΈΠΊΠ° ΡΠΎΠ·Π΄Π°Π½ΠΈΡ ΠΈ ΡΠΎΠ΄Π΅ΡΠΆΠ°Π½ΠΈΠ΅ Π½ΠΎΠ²ΠΎΠΉ Π±Π°Π·Ρ Π΄Π°Π½Π½ΡΡ

The article describes principles, methods and tasks of tectonic studies using computer processing of the Active Faults of Eurasia Database. This new database contains more than 30000 objects that are geographically linked, equipped with attributes of the kinematic type, estimated movement rates and activity confidence ranks. As an examβ ple, we consider processing of the data on several tectonic regions of the AlpineβHimalayan mobile belt and construction of roseβdiagrams of faults for a comparative analysis of their Late Cenozoic kinematics. The processed data set also covered the CaucasusβAnatolian region and the entire central part of the mobile belt, and fields of shortening/lengthening and shearing were mapped to assess the patterns of these processes in different areas and to determine the characteristics of the tectonic flow of the upper crust material. Prospects are discussed for the database processing with the use of all the available attributive information for structuralβkinematic and geodynamic analysis, including processing of the database in combination with independent remote and geophysical data.ΠΠΏΠΈΡΡΠ²Π°ΡΡΡΡ ΠΏΡΠΈΠ½ΡΠΈΠΏΡ, ΠΌΠ΅ΡΠΎΠ΄ΠΈΠΊΠΈ ΠΈ Π·Π°Π΄Π°ΡΠΈ ΡΠ΅ΠΊΡΠΎΠ½ΠΈΡΠ΅ΡΠΊΠΈΡ

Composition, crystallization conditions and genesis of sulfide-saturated parental melts of olivine-phyric rocks from Kamchatsky Mys (Kamchatka, Russia)
Highlights
β’ Parental melts of sulfide-bearing KM rocks have near primary MORB-like composition.
β’ Crystallization of these S-saturated melts occurred in near-surface conditions.
β’ Extensive fractionation and crustal assimilation are not the causes of S-saturation.
β’ S content in melts can be restored by accounting for daughter sulfide globules.
Abstract
Sulfide liquids that immiscibly separate from silicate melts in different magmatic processes accumulate chalcophile metals and may represent important sources of the metals in Earth's crust for the formation of ore deposits. Sulfide phases commonly found in some primitive mid-ocean ridge basalts (MORB) may support the occurrence of sulfide immiscibility in the crust without requiring magma contamination and/or extensive fractionation. However, the records of incipient sulfide melts in equilibrium with primitive high-Mg olivine and Cr-spinel are scarce. Sulfide globules in olivine phenocrysts in picritic rocks of MORB-affinity at Kamchatsky Mys (Eastern Kamchatka, Russia) represent a well-documented example of natural immiscibility in primitive oceanic magmas. Our study examines the conditions of silicate-sulfide immiscibility in these magmas by reporting high precision data on the compositions of Cr-spinel and silicate melt inclusions, hosted in Mg-rich olivine (86.9β90β―mol% Fo), which also contain globules of magmatic sulfide melt. Major and trace element contents of reconstructed parental silicate melts, redox conditions (ΞQFMβ―=β―+0.1β―Β±β―0.16 (1Ο) log. units) and crystallization temperature (1200β1285β―Β°C), as well as mantle potential temperatures (~1350β―Β°C), correspond to typical MORB values. We show that nearly 50% of sulfur could be captured in daughter sulfide globules even in reheated melt inclusions, which could lead to a significant underestimation of sulfur content in reconstructed silicate melts. The saturation of these melts in sulfur appears to be unrelated to the effects of melt crystallization and crustal assimilation, so we discuss the reasons for the S variations in reconstructed melts and the influence of pressure and other parameters on the SCSS (Sulfur Content at Sulfide Saturation)
Active Tectonics and Geomorphology of the Kamchatsky Bay Coast in Kamchatka
Kamchatsky Bay is the northernmost bay at the Pacific Kamchatka coast. It is located at the junction between the Kamchatka segment of the Pacific subduction zone and the dextral transform fault of the western Aleutians. The combination of the subduction and collision processes in this region results in the unique set of tectonic controls influencing its geological and geomorphological evolution.
The Kamchatka River estuarine area is located on the northern coast of Kamchatsky Bay. The modern Kamchatka River valley, its estuary, and an aggradation marine terrace some 30 km long and up to 5 km wide were formed in this area during the Holocene. A vast area in the rear part of the terrace and in the Stolbovskaya lowlands is now occupied by the peats deposited directly above lacustrineβlagoonal and fluvial facies. These aggradational landforms record traces of tsunamis and vertical coseismic deformations associated with great subduction earthquakes, as well as strikeslip and thrust faulting associated with the collision.
The results indicate that the average recurrence interval for major tsunamis in the Kamchatsky Bay is 300 years. The recurrence interval on individual fault zones associated with the collision between the western Aleutian and Kamchatka arcs is a few thousand years for earthquakes of magnitude between 7 and 7.5. For the entire region, the recurrence interval for major crustal earthquakes associated with motions along faults may be equal to a few hundred years, which is comparable with that for subductionzone earthquakes
