The impact of the fostering of European industry and Victorian national feeling on African music knowledge systems: Considering possible positive implications
Authors: Gibson Dylan Lawrence
Published: November 2019

The European (Victorian) missionary influence on traditional African music in South Africa is largely seen in a negative light and not much focus is placed on possible positive implications. This article therefore serves to explore how external European influences, harnessed by some African musicians, partially aided in preserving and generating conceivably ‘new’ Euro-African hybrid traditional music genres – while at the same time preserving some fragmented forms of indigenous music knowledge for future generations. In general, the ultimate aim for the European missionaries was to allow Africans to, in effect, colonize ‘themselves’ by using their influence of Victorian (British nationalist) religion, education, technology, music and language as a means to socially ‘improve’ and ‘tame’ the ‘wild’ Africans. However, specifically with reference to music, African composers and arrangers – despite this colonizing influence – occasionally retained a musical ‘uniqueness’. John Knox Bokwe, an important figure in what can be termed the ‘Black Intellect’ movement, displays this sense of African musical uniqueness. His arrangement of ‘Ntsikana’s Bell’, preserved for future generations in the Victorian style of notation (or a version thereof), best illustrates the remnants of a popular cultural African indigenous musical quality that has been combined with the European cultural tonic sol-fa influence. Furthermore, the establishment of the popular cultural ‘Cape coloured voices’ also serves to illustrate one dimension of the positive implications that the fostering of European industry (industrialized developments) and Victorian national feeling/nationalism left behind. This is largely because this choral genre can be termed as a distinctly ‘new’ African style that contains missionary influence but that still retains an exclusive African quality.
Temporal tapestries: Transforming cityscapes in Berlin pop music videos
Authors: Stehle Maria
Published: November 2019

This article analyses a selection of pop music videos released between 2012 and 2014 that rescript Berlin’s Zeitlichkeit (temporality), the relationship between city spaces, history, and time. Examples include videos by German and non-German artists, ranging from David Bowie to Miss Platnum, Lilly Wood & the Prick, Alanis Morissette and Andreas Bourani. Striking synergies between the different sound-image-texts emerge around questions of historic memory, time, and time passing. Close analyses show how these Berlin music videos released between 2012 and 2014 challenge linear narratives of pasts and progress. In the non-linear conceptions of time suggested in these videos and songs, new and old agents can coexist and create images and narratives of a different temporal tapestry of the city.
Nostalgia, community and resistance: Counter-cultural politics in a Finnish skinzine
Authors: Kotonen Tommi
Published: November 2019

Culture and community building are an essential part of the appeal of the far-right and fascist movements. Studying their cultural products is therefore important for a deeper understanding of the movement and their modus operandi. One elemental part of their culture are the so-called zines, small-scale do-it-yourself magazines intended for scene members. In certain respects, the far-right zines, skinzines, follow the forms and trends of other underground publications, especially punk-zines, with which they also share the resistance identity as stigmatized and marginalized actors. However, the political visions in skinzines are more or less opposite to ‘democratic zines’, creating certain tension between their political goals and the general media logic. In this article, I will explore a Finnish skinzine Ukonvasama and their community, analysing the efforts to build a nationalist movement and to mobilize support in relation to a retreat to nostalgic counter-culture they also promote. Ukonvasama is both a nostalgic project of former skinheads and a political project of far-right activists.
A növekedési hormon és az inzulinszerű növekedési faktorok élettani szerepe

Abstract:

The existence of insulin-like growth factors (IGFs) was recognized in connection with the stimulation of sulfate incorporation into cartilage. IGFs take part in the embryonal development and postnatal growth, in interaction with the growth hormone (GH). The physiological effects of IGF1 are promotion of tissue growth and development, stimulation of cell proliferation, effects on lipid and carbohydrate metabolism, anti-aging, anti-inflammatory, anabolic, anti-oxidant, neuro- and hepatoprotective properties. Our knowledge about the GH/IGF axis is diverse, partly contradictory, their research is continued intensively nowadays. We considered it worthwhile to review and interpret this information. Study on GH/IGF medical reports, with particular reference to the less known metabolic control. 75% of the growth factors are produced in the liver by GH and insulin stimulation; their effects are expressed on specific receptors, and modified by specific binding proteins. IGF1 directly increases the muscle mass, bone density, and the structure of the bones. Intestinal microbiota induces secretion of IGF1, which promotes the development and remodeling of the bones. Short-chain fatty acids, produced in microbial fermented fibers, induce secretion of IGF1, suggesting that microbial activity also affects bone health via IGF1. IGF1 also has a direct and indirect glucose-lowering effect, enhances free fatty acid oxidation in the muscle, reducing the flow of free fatty acid into the liver, improving insulin signaling, resulting in the reduction of hepatic glucose output, and improves insulin sensitivity. IGF1 directly influences the expression of circadian BMAL1 in hypothalamic cells: this refers to the newly recognized ’zeitgeber’ role of IGF1. The bioactivity of insulin-like peptides in the brain is characterized by neuronal survival, excitatory and inhibitory neurotransmission, maintenance of normal free fatty acid levels, improvement of cognitive function, protection against cell damage, neurogenesis and angiogenesis. The effects of IGF2 are less outlined, however, it has a relevant role in the development of the fetus, and acts protectively on the brain. Lack or over-expression of IGF1 can be detected or may causally associated in many pathological conditions. According to these collected data, insulin sensitivity may be improved by different pathways. The role of IGFs in these processes should be a task of future research.

Abstract:

Introduction: It is known that lactate concentration is increased in diabetic ketoacidosis (DKA), however, the pathophysiology and kinetics of lactate changes are still unclear. Normally, L-lactate is the major form in the human body. According to previous data, also D- and L-lactate might be increased in hyperglycaemic disorders. Aim: We aimed to describe the kinetics and mechanisms of lactate concentration changes in ketoacidosis and newly diagnosed diabetes. Method: We performed a prospective study, including 5–18-year-old children with ketoacidosis (DKA, n = 13) and with newly diagnosed type 1 diabetes without ketoacidosis (T1DM, n = 6). We performed routine blood gas analysis 0–12–24–48 hours after admission, which also measured L-lactate levels. We also determined total venous serum lactate level by gas chromatography–mass spectrometry. Results: Initial plasma lactate concentration was increased in ketoacidosis as compared to the newly diagnosed diabetes group (p<0.05). After 12 h of rehydration, lactate levels were greatly reduced in ketoacidotic patients but after 24–48 h it was repeatedly increased (all p<0.01). In the 0–12 h phase, total serum lactate level was higher than L-lactate level, referring to D-lactate production. Conclusion: We described two L-lactate peaks in ketoacidosis. In the first 12 hours anaerobic glycolysis seems to have major role in hyperlactataemia. We assume that stimulated aerobic glycolysis leads to the second lactate peak. However, D-lactate is not routinely measured, it may contribute to the initial hyperlactataemia in both groups and is comparable to L-lactate production in ketoacidosis.

Abstract:

Introduction: There are conflicting data on the prevalence and prognosis of AMI patients with non-obstructive coronary artery disease (MINOCA). Aim: We studied the prevalence and prognosis of MINOCA patients. Method: In the Hungarian Myocardial Infarction Registry (HUMIR) 45,223 patients (pts) with acute myocardial infarction (AMI) were found who were treated between Jan 1, 2014, and June 30, 2018, and coronary arteriography was performed. ST-elevation myocardial infarction was diagnosed in 22,469 pts (49.7%). Patients without obstructive coronary artery disease who had no previous myocardial infarction, heart failure, PCI and CABG procedure were selected to the MINOCA group (n = 2003). Patients with obstructive coronary artery disease belonged to the MICAD group (n = 43,220). We investigated clinical characteristics of the patients, overall survival and reinfarction. Survival curves were estimated with the Kaplan–Meier method and were modeled with the Cox proportional hazards model. Results: The proportion of MINOCA pts among all myocardial infarction was by 4.4% higher in the STEMI pts compared to the NSTEMI group (2.0% vs. 6.8%). The MINOCA pts were younger (age 64.0 ± 14.4 vs. 65.5 ± 12.2 years), and the proportion of women was higher (55.7% vs. 36.5%). Hypertension, diabetes mellitus and peripheral artery disease were more common in the MICAD group (79.1% vs. 73.7%, 33.0% vs. 21.2%, and 12% vs. 8%). The mortality was higher among the MICAD pts. In the MINOCA group, the mortality of men did not differ between STEMI and NSTEMI, as opposed to women: women with STEMI had higher mortality than women with NSTEMI. The risk of reinfarction was higher in the MICAD group, especially in NSTEMI, the risk in the MINOCA group was lower, and there was no substantial difference between types. Conclusion: In this real word, retrospective, observational study, we found a significant difference in the prevalence of MINOCA pts according to different types of myocardial infarction. In the MINOCA group, the mortality of women with STEMI was substantially higher. Orv Hetil. 2019; 160(45): 1791–1797.
Mit tudunk az e-cigaretta káros hatásairól?

Abstract:

Electronic cigarettes are becoming increasingly popular with smokers worldwide. This has created an entirely new public health dilemma. The central issue in the debate is the disease risk imposed by e-cigarettes. It is generally acknowledged that e-cigarettes are unlikely to be as harmful as conventional cigarettes, but there are little data that quantify their relative harms. Experiments in cell cultures and animal studies show that e-cigarettes can have multiple negative effects. Scientific evidence regarding their human acute health effects is limited. The long term effects in humans are unknown, and there is no evidence that e-cigarettes are safer than tobacco in the long term. This review higlights the recent data regarding e-cigarettes toxicity impact on lung and cardiovascular system. Orv Hetil. 2019; 160(45): 1767–1773.

Aim.To study the association of T715P (rs6136), M62I (rs2228315), S290N (rs6131), V640L (rs6133) polymorphisms in the P-selectin gene with resistance to acetylsalicylic acid (ASA) in patients with coronary artery disease after coronary artery bypass grafting (CABG).

Material and methods. The study included 90 patients aged 61,5±6,9 years (70 men and 20 women) with II-IV functional class (FC) angina pectoris, according to the Canadian Cardiovascular Society grading. The atherosclerotic nature of coronary artery disease is confirmed by coronary angiography. Patients stopped taking antiplatelet agents before CABG for at least 5 days. The aggregation study was carried out with an optical aggregometer using ADP inducers (5 pM) and arachidonic acid (1 µМ) before CABG, on 1-3 and 8-10 days after surgical treatment.

DNA samples were examined for the presence of T715P (rs6136), M62I (rs2228315), S290N (rs6131), V640L (rs6133) polymorphisms in the P-selectin gene using realtime PCR with allele-specific primers.

Results.When comparing aPTT, fibrinogen level, platelet aggregation activity with ADP inducers (5 µМ) and arachidonic acid (1 µМ), no differences were found among groups of patients with homozygous and heterozygous variants of the studied polymorphisms genotypes, both before and on 1-3, 8 -10 days after CABG. Regarding presence of ASA resistance, patient groups with homozygous variants of genotypes (T715P (rs6136), M62I (rs2228315), S290N (rs6131), V640L (rs6133)) did not statistically differ in prevailing or rare alleles from the corresponding groups with heterozygous genotypes. In the first 10 days of the postoperative period, thrombotic events (4,4%) were observed in 4 patients in the study group: acute myocardial infarction, acute cerebrovascular accident. Regarding frequency of adverse events in the first 10 days after CABG, between groups of patients with homozygous variants of the studied genotypes (T715P (rs6136), M62I (rs2228315), S290N (rs6131), V640L (rs6133) in prevailing allele and groups with heterozygous variants of the corresponding genotypes there were also no statistically significant differences.

Conclusion.Rs6133, rs6163, rs2228315, rs6131 polymorphisms in the platelet P-selectin gene are not associated with ASA resistance and are not associated with increased platelet aggregation activity in patients with coronary artery disease. The rare T, C, G, A alleles of the studied polymorphisms do not lead to an increase in the risks of adverse events in the first 10 days after CABG.

Aim. To confirm the association between sudden cardiac death (SCD) and single nucleotide polymorphisms rs7164665, rs71461059, rs74765750, rs6762529, identified in own genome-wide associative study as new molecular genetic markers of SCD.

Material and methods. As design we used case-control study. The SCD group was formed using the SCD criteria of the European Society of Cardiology (n=438, average age 53,2±9,1 years, male — 72,7%, women — 28,3%). The control group (n=435, average age 53,2±8,9 years, men — 70,0%, women — 30,0%) was selected by gender and age for the SCD group from the DNA bank of the international projects MONICA and HAPIEE. DNA was isolated by phenol-chloroform extraction from myocardial tissue in the SCD group and venous blood in the control group. Genotyping was performed by polymerase chain reaction followed by analysis of estriction fragment length polymorphism. The results are statistically processed using the SPSS 16.0 software package.

Results. No carriers of the rare allele A of the single nucleotide polymorphism rs74765750 were found in the SCD group and the control group. No statistically significant differences were found between the SCD group and the control group relating to frequencies of genotypes and alleles of single nucleotide polymorphisms rs7164665 and rs71461059. In the age group older than 50 years, the proportion of carriers of the heterozygous CT genotype of the single nucleotide polymorphism rs6762529 in the SCD group is statistically significantly lower compared to the control group (CT vs CC+TT: OR=0,686, 95% CI 0,483-0,967 p=0,035).

Conclusion. The CT genotype of the single nucleotide polymorphism rs6762529 is associated with a protective effect on SCD for people over 50 years of age. The association with single nucleotide polymorphisms rs7164665, rs71461059, rs74765750 with SCD has not been confirmed.

Authors: Rai Sunil , Das Saurav , Narayan Shankar
Published: November 2019

Background: Vitamin D deficiency during pregnancy and in newborn period is common in this country. Vitamin D status of the mother is known to influence the vitamin D levels in the neonate, however how closely the maternal vitamin D level correlates with the cord blood Vitamin D is not clearly understood. To study the correlation between maternal and neonatal serum Vitamin D3 levels by as indicated by cord blood 25(OH)D levels and find out if there is a significant variation of cord blood 25(OH)D levels in Vitamin D sufficient and insufficient mothers.Methods: Healthy pregnant women between 18-45 years of age with no known history of chronic disease or long-term medication, consenting for the study were enrolled. Maternal blood sample was collected in peripartum period, cord blood sample was obtained after delivery from the umbilical cord after clamping. Vitamin D3 levels were measured by RIA and paired maternal and cord blood levels were statistically analyzed.Results: 569 paired samples of maternal and cord blood were analyzed. The mean maternal serum 25(OH)D level was 35.63ng/ml (sd 6.18, range 9.2-39.8) as compared to 13.52ng/ml (sd 3.79, range 7.9-27) for the neonates. 457 of the mothers were found to have sufficient, 101(18%) insufficient and 11(2%) deficient Vitamin D levels as per Endocrinological Society guidelines. In comparison, 535(94%) of the neonates had deficient levels, none of the neonates had sufficient Vitamin D levels, 34(5.99%) had insufficient levels. No significant correlation was found between maternal and neonatal serum vitamin 25(OH)D levels (r=0.007, P=0.85).Conclusions: Maternal and Cord blood serum Vitamin D3 levels were found to be poorly correlated in this study.

Published: November 2019

Purpose of Study: The paper aims to assess the new face of retailing after demonetization with specific focus to the role of financial intermediaries and it also focuses on Long term solutions to drive the digital cash enabled retailing in India.

Methodology: This study used a questionnaire for data collection among 250 retailers in Uttarakhand, India. The questionnaire was later on analyzed using SPSS. Qualitative data was gathered from the interview with the officials from 100 financial intermediaries from banks.

Findings: The Indian retail market has been fostered by the cash dealings. The step of demonetization caught the black marketers, retailers and common people by surprise. The move was supported by the majority of people despite facing difficulties.  After the demonetization, people started using the adoption of different forms of digital payment options. The trade in the market was affected and the retail sales witnessed a severe dip. The market is recovering but the actual recovery will depend on devising the substitute for the cash payments at all levels of retailers.

Social implications: Financial inclusion is important for inclusive growth and bank to have a crucial role to play in financial literacy campaigns and should ensure that those deprived sections that come to exchange their old notes are properly taken care of. Banks could make unbanked people aware about the financial instruments available with banks and the importance of saving and putting their money in these instruments. This step would further help the economy move from unorganized to organized sector.

The originality of Study: This study is original and first of its kind conducted in Uttarakhand, India.

Estimating Biomechanical Time-Series with Wearable Sensors: A Systematic Review of Machine Learning Techniques
Authors: Gurchiek Reed D. , Cheney Nicholas , McGinnis Ryan S.
Published: November 2019

Wearable sensors have the potential to enable comprehensive patient characterization and optimized clinical intervention. Critical to realizing this vision is accurate estimation of biomechanical time-series in daily-life, including joint, segment, and muscle kinetics and kinematics, from wearable sensor data. The use of physical models for estimation of these quantities often requires many wearable devices making practical implementation more difficult. However, regression techniques may provide a viable alternative by allowing the use of a reduced number of sensors for estimating biomechanical time-series. Herein, we review 46 articles that used regression algorithms to estimate joint, segment, and muscle kinematics and kinetics. We present a high-level comparison of the many different techniques identified and discuss the implications of our findings concerning practical implementation and further improving estimation accuracy. In particular, we found that several studies report the incorporation of domain knowledge often yielded superior performance. Further, most models were trained on small datasets in which case nonparametric regression often performed best. No models were open-sourced, and most were subject-specific and not validated on impaired populations. Future research should focus on developing open-source algorithms using complementary physics-based and machine learning techniques that are validated in clinically impaired populations. This approach may further improve estimation performance and reduce barriers to clinical adoption.
