The paper deals with the problem of the establishment of capitalism in Russia in the late 19 - early 20th centuries. Using a wide array of historical research and documents the author argues that the thesis on the advanced state of capitalism in Russia in the beginning of the 20th century does not stand up to historical scrutiny, and the role of the famous Emancipation reform of 1861 appears to be of limited importance.

Even though the role of lipids in pandemic diseases such as obesity and diabetes is a focus of increasing research, the role of lipids during organogenesis, when diverse diseases may be triggered, is unexplored. Also, pig embryonic tissues represent an attractive option for organ transplantation. This study introduces a detailed morphological analysis of swine fetal tissues with matching location of lipids acquired by desorption electrospray ionization mass spectrometry (DESI-MS) imaging for the study of differential distribution of free fatty acids (FFA) and phospholipids (PL) in specific organs during fetal development. Samples from a pig fetuses around Day 50 of pregnancy were sectioned at a cryotome and mounted onto glass slides. Fixative agents were not used. DESI-MS images were run with a step size of 300 µm using a morphologically friendly (non-destructive) solvent combination, namely dimethylformamide/acetonitrile 1 : 1 (v/v). Data were acquired in the negative ion mode in the m/z range of 150 to 1000 from different sections representing the whole swine fetus body. Ion images were constructed using BioMAP software. After imaging, the whole-body tissue samples were stained with hematoxylin and eosin (H&E) and were overlaid to the DESI-MS lipid images. Differential distribution of FFA, phosphatidylcholines (PC), phosphatidylserines (PS), sulphatides (ST), and phosphatidylinositols (PI) was observed among organs, especially on nervous and circulatory systems, and digestive glands. Most lipids concentrated in the brain, spinal cord, and digestive glands such as the liver. For example, arachidonic acid was most abundant in neuronal tissue, whereas docosahexaenoic acid predominated in the liver and digestive glands. Distribution of PS (36 : 1) of m/z 788 was observed in all tissues except for the digestive system, but PS (40 : 6) of m/z 834.7 was exclusive of brain and spinal cord. Lipids related to brain and spinal cord were mostly polyunsaturated fatty acids as well as specific PS lipids. Arachidonic and eicosatrienoic acids are more concentrated in hindbrain and spinal cord, whereas PS was more abundant in the brain than in the spinal cord. There is no information on PS chemical composition during brain and spinal cord development, but PS concentration in the nervous tissue membranes varies with age, brain areas, cell type, and subcellular components. Several reports indicate that alteration in PS synthesis might participate in the mechanism of brain damage. Also, PS has been found to be altered in brain tumours. Oleic acid, fatty acid dimers, and the signalling lipid PI (38 : 3) were most significant for the digestive system and liver. Liver is one of the main organs involved in fatty acid metabolism (besides adipose tissue and muscle). By overlying morphological and molecular information, lipids seem to be a major player in the organogenesis process.

The Riga Latvian Society (RLS) is the oldest Latvian organization in the world, where students, graduates and academic staff from oldest universities in the territory of Latvia – the Riga Polytechnicum (RP), from 1896 – the Riga Polytechnic Institute (RPI), had worked. The activities of the Society and its members have been diverse and varied, and their results are different, too. The heritage preserved for the future is books compiled and translated by Latvians that are well-known folk historical and cultural values, and new educated, patriotic generations of Latvians. Poor students were supported as much as possible, enabling them to achieve their chosen goals and contribute to Latvia’s economic and national development, culture and education. The 150th anniversary of the RLS, the collaboration of the Society with the RP / RPI students, graduates and academic staff until 1919, has been studied.

Cardiac arrhythmias occur frequently in patients with acute stroke, with atrial fibrillation (AF) being the most common. Newly detected AF may lead to increased risk of ischemic stroke, which in turn generates stroke recurrence and adverse outcomes. Currently, most studies are focusing on the role of AF in ischemic stroke and attributing cryptogenic ischemic stroke to previously undetected AF. However, in these studies, subjects used to have neither symptoms of palpitation nor evidence of AF. A better understanding of this association will contribute to the management and therapy for patients after clinical decisions regarding stroke patients. Currently, the definition of newly detected AF has not come to an agreement, and the pathophysiology remains incompletely understood, possibly involving complex alterations in both the autonomic network and humoral regulation. Therefore, this review aims to introduce the definition and epidemiology of newly detected AF after stroke with updated information and elucidate the potential pathophysi­ology, such as autonomic imbalance, catecholamine surge, poststroke systematic inflammation, and microvesicles and microRNAs.

Highlights The findings of this original study ensure the detection of violations in the humoral regulation of the maternal immune interactions with semiallogeneic fetus, considered as a risk factor for developing sporadic conotruncal heart malformations in the next generation.Aim To study the role of female autoserum blood in limiting allogeneic interactions in short-term lymphocyte cultures of parents having children with conotruncal heart malformations.Methods 21 married couples (the study group) with children suffering from conotrucnal heart malformations (Tetralogy of Fallot) without chromosomal diseases were examined. The control group consisted of 21 families with three or more healthy children. The immune response in a mixed lymphocyte culture of parents was assessed by the increase in HLA-DR expression in the mixed culture with respect to spontaneous lymphocyte cultures. Primary staining of female and male lymphocytes with monoclonal antibodies to CD45, conjugated with various fluorescent dyes (PC-5 and PC-7), allowed assessing the immune response of female lymphocytes to male and vice versa.Results The effects of female autoserum on the mixed lymphocyte culture of parents were assessed. The obtained results reported that the birth of children with conotruncal heart malformations is associated with the interfering effect of female autoserum on HLA-DR expression on subpopulations of female lymphocytes (CD3+, HLA-DR+) and the activating effect on subpopulations of female lymphocytes (CD3-, HLA-DR+). The observed role of female autoserum in the study group may be associated with the absence of HLA-DR-blocking autoantibodies and high synthesis of cytokines by T2 and T3 helper lymphocytes.Conclusion The effects of female autoserum on allogeneic lymphocyte interactions of parents may be observed in short-term mixed lymphocyte cultures. The evaluation of the activating and interfering effects ensures timely identification of any violations in the humoral regulation of the maternal immune interactions with the HLA semiallogenic fetus, considered as a risk factor for developing sporadic conotruncal heart malformations in the next generation.
