Бухтарминские старообрядцы как этноконфессиональная группа в СССР в постосоветской русскоязычной историографии
Authors: Латышев Кирилл А. 
Published: May 2024

In the study, using the comparative historical method, the post-Soviet historiography of the history of the Bukhtarma Old Believers is studied. The author studies Russian post-Soviet historiography and Qazaq post-Soviet Russian-language historiography. The most important scientific problems and approaches to the study of the history of the Old Believers are highlighted and compared. The article contributes to the discussion of why it is necessary to jointly study the achievements of both Russian and Qazaq post-Soviet historiography. The author reveals the expansion of the modern ethnographic framework in the study of the Bukhtarma Old Believers. The problem of the identification of the Bukhtarma Old Believers in modern historical literature is revealed. The author notes that in the last decade, new studies have appeared in which the Bukhtarma Old Believers are identified with the Old Believers of Altai. Modern Russian and Qazaq historians systematically turn to Soviet historiography. Soviet historical studies written in the 1920s and 1930s act as a historical source. The author analyzes the historiography of the most important problems in the history of the Bukhtarma Old Believers. The most significant problems are Soviet repression, preservation of identity, and preservation of traditionalism. The historiography presents case studies on selected issues related to common scientific problems. The author concludes that the historiography of modern Bukhtarma Old Believers can successfully develop as a single “post-Soviet Russian-language historiography.” National historiography is inferior in depth to scientific analysis.

Background
Ageing is a key risk factor for cardiovascular disease and is linked to several alterations in cardiac structure and function, including left ventricular hypertrophy and increased cardiomyocyte volume, as well as a decline in the number of cardiomyocytes and ventricular dysfunction, emphasizing the pathological impacts of cardiomyocyte ageing. Dental pulp stem cells (DPSCs) are promising as a cellular therapeutic source due to their minimally invasive surgical approach and remarkable proliferative ability.

Aim
This study is the first to investigate the outcomes of the systemic transplantation of DPSCs in a D-galactose (D-gal)-induced rat model of cardiac ageing. Methods. Thirty 9-week-old Sprague-Dawley male rats were randomly assigned into three groups: control, ageing (D-gal), and transplanted groups (D-gal + DPSCs). D-gal (300 mg/kg/day) was administered intraperitoneally daily for 8 weeks. The rats in the transplantation group were intravenously injected with DPSCs at a dose of 1 × 106 once every 2 weeks.

Results
The transplanted cells migrated to the heart, differentiated into cardiomyocytes, improved cardiac function, upregulated Sirt1 expression, exerted antioxidative effects, modulated connexin-43 expression, attenuated cardiac histopathological alterations, and had anti-senescent and anti-apoptotic effects.

Conclusion
Our results reveal the beneficial effects of DPSC transplantation in a cardiac ageing rat model, suggesting their potential as a viable cell therapy for ageing hearts.
Audit Committee, Firm Size on Tax Avoidance: Profitability as a Mediator
Authors: Putri Octa Ramadina , Rochayatun Sulis 
Published: May 2024

Aims: This study investigates tax avoidance strategies in Indonesia's property and real estate industry, considering firm size, profitability, and audit committee as variables.
Study Design: A quantitative study is used to collect data that can be measured in numbers and analysed statistically.
Place and Duration of Study: Engaging 15 businesses in the property and real estate industry that has maintained a presence on the Indonesia Stock Exchange for a decade.
Methodology: In the study, an empirical analysis was conducted using data contained in the company's financial statements to test tax avoidance in Indonesia. This study used a sample of 150 selected through a purposive sampling approach. The sample was then analysed by testing the direct effects and indirect effects using Path Analysis. In this study, the analysis technique used was SPSS 24 software.
Results: The results show a strong relationship between tax evasion, firm size, profitability, and the audit committee. Furthermore, it has been demonstrated that the audit committee, firm size, and tax avoidance can all be mediated by profitability. It is important to remember that when profitability is strong, there is a greater chance of tax avoidance.
Conclusion: Further research is expected to expand the coverage by using more companies from different sectors, as well as adding additional variables as part of the analysis. This is important because the research focuses only on one sector and uses a limited number of samples. For investors, assessing the profitability of companies and compliance with tax regulations becomes crucial to identifying potential investment risks.

Published: May 2024

Aims: This experiment was conducted to assess the effect of different chemical preservative in vase life and quality of gerbera cut flowers.
Study Design: Completely Randomized Design (CRD).
Place and Duration of Study: Department of Horticulture, Prithvi Secondary School, Nawalparsi (East), Nepal, between June 2023 and September 2023.
Methodology: Eight different preservative solutions of different concentrations (i.e. 4% sucrose, 200 ppm citric acid, 200 ppm salicylic acid and 1% CaCl2) and their combinations including control treatment i.e. sole application of distilled water were replicated thrice. And, the parameters like water solution uptake, flower weight, flower diameter, stem bending and vase life was observed.
Results: The study revealed that among seven different vase solutions, the combination of 4% sucrose + 200 ppm citric acid was found superior for all the parameters observed and supposed to be the most effective vase solutions for prolonging the vase life and reducing the postharvest losses in gerbera.
Conclusion: For achieving better quality of gerbera cut flowers, they are better to be treated with sucrose in combination with citric acid or CaCl2, thus can satisfactorily be recommended for commercial growers, wholesalers and retailers.

Authors: Harry Nkechinyere Mary , Folorunsho Ibrahim , Anona Kenechukwu , Okafor Nnenna , Anugwom Gibson O. 
Published: May 2024

Background: Pseudocyesis (or pseudocyesis vera) also known as “phantom pregnancy” was previously described according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a false belief of being pregnant that is associated with objective signs and reported symptoms of pregnancy. The exact etiology and management of this rare disorder are not known but certain factors have been associated with this including the presence of certain psychiatric conditions.
Objective: This study aims to provide a better understanding of the factors associated with pseudocyesis including psychiatric disorders and available treatment modalities.
Materials and Methods: A comprehensive review of literature on pseudocyesis in humans and its association with various psychiatric conditions. Available articles published from 1970 to January 2021 were included. Using the following keywords- “pseudocyesis, false pregnancy, psychiatric disorders, schizophrenia, phantom pregnancy”, relevant articles from Google Scholar, PubMed, ScienceDirect, and Web of Science were searched and reviewed. Our initial search yielded 871 articles, out of which 14 were deemed fully eligible.
Results: According to our review, it has been found that various social and cultural factors such as strong cultural views on the need for childbearing as prerequisite for womanhood have led to the manifestation of this condition. The etiology of pseudocyesis is associated with various psychological and endocrine disturbances sometimes mediated by psychosomatic disorders.
Conclusion: Pseudocyesis could be associated with psychiatric conditions such as major depression, schizophrenia, bipolar disorder, hypomania, and post-traumatic stress disorder. The treatment options may vary according to the presence of co-morbidities in different patients. Adopting a multidisciplinary approach encompassing gynecologists, psychologists and psychiatrists, is important in providing holistic care for this group of patients.

Published: May 2024

Aims: The current investigation was to ascertain the most efficient sporicidal treatment for germinated finger millet in order to inactivate the spores that could interfere with the fermentation process by acting as a competing microflora for starter culture during the manufacturing of probiotic millet food.
Study Design: By applying different dry and wet sporicidal treatments to the finger millet, the study attempted to inactivate the spores and create germinated finger millet. Following each treatment, the number of aerobic spores was enumerated by the pour plate technique.
Place and Duration of Study: Department of Dairy Microbiology, Dairy Science College, Hebbal, Bengaluru, Karnataka, India between June 2023 and April 2024.
Methodology: Both wet and dry sporicidal treatments were used. It comprised of blanching, autoclaving, hot air oven treatment and the combined treatment of hot air oven and autoclaving.
Results: Aerobic spore count were reduced from 3.86 to 1.00 log10 cfu/g after autoclaving finger millet for 30 min at 121℃. Considering that the autoclaving procedure did not encourage germination, sporicidal and fungicidal treatments were followed for 48 h germinated finger millet. After autoclaving germinated finger millet flour, the initial counts of spores and fungus which were 4.98 and 3.56 log10 cfu/g were completely eliminated. Statistically significant (P=.05) difference was found between the treatment sample and the control.
Conclusion: Autoclaving the germinated finger millet flour at 121℃ for 15 min resulted in a complete reduction of spores and fungus count. Hence, this treatment was followed during the preparation of probiotic millet food.

In Situ ATR‐FTIR Spectroscopy on the Deposition and Protein Interaction of Polycation/Alginate Multilayers
Authors: Müller Martin , Torger Bernhard , Keßler Bernd 
Published: November 2010

AbstractWe report in situ ATR‐FTIR spectroscopy studies of the deposition of biocompatible polyelectrolyte multilayers (PEMs) consisting of the polycation chitosan (CHT) or poly(ethyleneimine) (PEI) and the polyanion sodium alginate (ALG) and their interactions with model‐protein human serum albumin (HSA). HSA‐adsorption data for PEI/ALG and CHT/ALG PEMs show the importance of the outermost polyelectrolyte (PEL) layer for protein interactions: CHT‐ or PEI‐terminated PEMs are highly attractive to HSA, while ALG‐terminated PEMs are repulsive, relevant for the generation of protein‐active or protein‐inert biomedical surfaces. The bound HSA is found to be located at the surface rather than the inner region of the PEM.

AbstractCHD6 is an ATP‐dependent chromatin‐remodeling enzyme, which has been implicated as a crucial component for maintaining and regulating chromatin structure. CHD6 belongs to the largest subfamily, subfamily III (CHD6–9), of the chromodomain helicase DNA (CHD‐binding protein) family of enzymes (CHD1–9). Here we report on a female patient with a balanced translocation t(4;20)(q33;q12) presenting with severe mental retardation and brachydactyly of the toes. We identified the translocation breakpoint in intron 27 of CHD6 at 20q12, while the 4q33 breakpoint was intergenic. Northern blot analysis demonstrated the CHD6 mRNA in the patient's lymphoblastoid cells was decreased to ∼50% of the control cells. To investigate the cellular mechanism of diseases resulting from decreased CHD subfamily III proteins, we knocked down CHD6 or CHD7 by RNA interference in HeLa cells and analyzed chromosome alignment. The both CHD6‐ and CHD7‐knockdown cells showed increased frequency of misaligned chromosomes on metaphase plates. Moreover, an elevated frequency of aneuploidy, the major cause of miscarriages and mental retardation, was observed in patients with CHD6 and CHD7 haploinsufficiency. These results suggest that CHD6 and CHD7 play important roles in chromatin assembly during mitosis and that mitotic delay and/or impaired cell proliferation may be associated with pathogenesis of the diseases caused by CHD6 or CHD7 mutations. © 2010 Wiley‐Liss, Inc.
Neocortical and hippocampal volume loss in a human ciliopathy: A quantitative MRI study in Bardet–Biedl syndrome

Published: November 2010

AbstractCilia are ubiquitous cell surface organelles with diverse roles from embryogenesis to adult life. The neurodevelopmental functions of the cilium are currently under investigation in animal systems, but relevance to human brain development remains uncertain. We present the first systematic investigation of structural neuroanatomy in a ciliopathy—Bardet–Biedl syndrome (BBS). Qualitative and quantitative aspects of brain structure were evaluated via magnetic resonance imaging in 10 patients with BBS (ages 14–28 years). In comparison to age and gender‐matched healthy controls, BBS patients had significantly reduced total gray matter (GM) volume but no total white matter (WM) or cerebrospinal fluid volume changes. Voxel‐based morphometric analysis indicated regional GM volume loss bilaterally in the anterior temporal lobes and in the medial orbitofrontal cortex, and WM volume loss in the right inferior longitudinal fasciculus. Region‐of‐interest measurements revealed reduced volume of the hippocampus. Two patients were found to have ventriculomegaly. Global GM reduction and regional volume reductions in the temporal lobe may underlie the learning disabilities and behavioral problems experienced by some patients with BBS. These findings are consistent with previous observations in mouse models of BBS, and further implicate the cilium in neurodevelopmental processes relevant to human cognitive function. © 2010 Wiley‐Liss, Inc.

AbstractTourette Syndrome (TS) is diagnosed based upon clinical criteria including motor and vocal tics. We hypothesized that differences in exon expression and splicing might be useful for pathophysiology and diagnosis. To demonstrate exon expression and alternatively spliced gene differences in blood of individuals with TS compared to healthy controls (HC), RNA was isolated from the blood of 26 un‐medicated TS subjects and 23 HC. Each sample was run on Affymetrix Human Exon 1.0 ST (HuExon) arrays and on 3′ biased U133 Plus 2.0 (HuU133) arrays. To investigate the differentially expressed exons and transcripts, analyses of covariance (ANCOVA) were performed, controlling for age, gender, and batch. Differential alternative splicing patterns between TS and HC were identified using analyses of variance (ANOVA) models in Partek. Three hundred and seventy‐six exon probe sets were differentially expressed between TS and HC (rawP < 0.005, fold change >|1.2|) that separated TS and HC subjects using hierarchical clustering and Principal Components Analysis. The probe sets predicted TS compared to HC with a >90% sensitivity and specificity using a 10‐fold cross‐validation. Ninety genes (transcripts) had differential expression of a single exon (rawP < 0.005) and were predicted to be alternatively spliced (rawP < 0.05) in TS compared to HC. These preliminary findings might provide insight into the pathophysiology of TS and potentially provide prognostic and diagnostic biomarkers. However, the findings are tempered by the small sample size and multiple comparisons and require confirmation using PCR or deep RNA sequencing and a much larger patient population. © 2010 Wiley‐Liss, Inc.
Infantile muscular dystrophy in Canadian aboriginals is an αB‐crystallinopathy

Published: November 2010

AbstractObjective:A recessively transmitted fatal hypertonic infantile muscular dystrophy has been described in Canadian aboriginals. The affected infants present with progressive limb and axial muscle stiffness and develop severe respiratory insufficiency, and most die in the first year of life. We sought to determine the genetic basis of this disease.Methods:We performed histochemical, immunocytochemical, electron microscopy, and molecular genetic studies in a cohort of 12 patients affected by this disease.Results:Conventional histochemical and electron microscopy studies suggested myofibrillar myopathy (MFM). Therefore, we searched for ectopic expression of multiple proteins typical of MFM. Alpha B‐crystallin (αBC) expression was absent from all fibers using a monoclonal antibody raised against the entire protein. However, a monoclonal antibody directed against the first 10 residues of αBC immunostained portions of abnormal fibers. Pursuing this clue, we searched for mutations in the gene for αBC (CRYAB) in available DNA samples of 8 patients. All harbored a homozygous deletion, c.60C, predicting a Ser to Ala change at codon 21 and a stop codon after 23 missense residues (p.Ser21AlafsX24). Clinically unaffected parents were heterozygous for this mutation.Interpretation:The homozygous c.60delC in CRYAB pinpoints the genetic basis of the fatal infantile hypertonic muscular dystrophy of Canadian aboriginals. MFMs are typically transmitted by dominant inheritance, but in this disease the parental phenotype is rescued by limited expression of the highly truncated nonfunctional mutant gene product. The severe patient phenotype is due to homozygosity for the markedly hypomorphic allele. Ann Neurol, 2011

AbstractThe aim of this study was to investigate whether a moderate‐intensity static magnetic field (SMF) can enhance the killing effect of adriamycin (ADM) on K562 cells, and to explore the effects of SMF combined with ADM on K562 cells. We analyzed the metabolic activity of cells, cell cycle distribution, DNA damage, change in cell ultrastructure, and P‐glycoprotein (P‐gp) expression after K562 cells were exposed continuously to a uniform 8.8 mT SMF for 12 h, with or without ADM. Our results showed that the SMF combined with ADM (25 ng/ml) significantly inhibited the metabolic activity of K562 cells (P < 0.05), while neither ADM nor the SMF alone affected the metabolic activity of these cells. Cell ultrastructure was altered in the SMF + ADM group. For example, cell membrane was depressed, some protuberances were observable, and vacuoles in the cytoplasm became larger. Cells were arrested at the G2/M phase and DNA damage increased after cells were treated with the SMF plus ADM. ADM also induced the P‐gp expression. In contrast, in the SMF group and SMF + ADM group, the P‐gp expression was decreased compared with the ADM group. Taken together, our results showed that the 8.8 mT SMF enhanced the cytotoxity potency of ADM on K562 cells, and the decrease in P‐gp expression may be one reason underlying this effect.
