Published: June 2021

Abstract
Organo-magnesium compounds were shown to contribute significantly to the soluble carbon molecular complexity and diversity of meteorites, and their analysis increases our knowledge on carbon stabilization/sequestration processes in the asteroidal parent body. Here we present a new group of sulfur-magnesium-carboxylates detected using ultra–high-resolution mass spectrometry in a variety of meteorites. These novel compounds show increased abundance correlated with the thermal history of the asteroid parent bodies. By comparing the soluble organic extracts of 44 meteorites having experienced variable post-accretion history, we describe distinct organic compound patterns of sulfur-magnesium-carboxylates in relation to their long- and short-duration thermal history. It is shown that the exceptional stability of these molecules enables survival of carbon under harsh thermal extraterrestrial conditions, even in the vitrified fusion crust formed during entry into the Earth's atmosphere. Sulfur-magnesium-carboxylates augment our understanding of parent body proceedings with regard to carbon sequestration and speciation in space.
On the Binary Neutron Star Post-merger Magnetar Origin of XRT 210423
Authors: Ai Shunke , Zhang Bing 
Published: June 2021

Abstract
XRT 201423 is an X-ray transient with a nearly flat plateau lasting 4.1 ks followed by a steep decay. This feature indicates that it might come from a magnetar formed through a binary neutron star (BNS) merger, similar to CDF-S XT2 and as predicted as a type of electromagnetic counterpart of BNS mergers. We test the compliance of the data with this model and use the observed duration and flux of the X-ray signal as well as upper limits of optical emission to pose constraints on the parameters of the underlying putative magnetar. Both the free zone and trapped zone geometric configurations are considered. We find that the data are generally consistent with such a model. The surface dipolar magnetic field and the ellipticity of the magnetar should satisfy B

p
< 7 × 1014G (B

p
< 4.9 × 1014G) and ϵ < 1.5 × 10−3 (ϵ < 1.1 × 10−3) under free zone (trapped zone) configurations, respectively. An upper limit on the distance (e.g., z < 0.55 with η

x
= 10−4 or z < 3.5 with η

x
= 10−2) can be derived from the X-ray data, which depends on the X-ray dissipation efficiency η

x
of the spin-down luminosity. The nondetection of an optical counterpart places a conservative lower limit on the distance of the source, i.e., z > 0.045 regardless of the geometric configuration.

Authors: Wibowo Agus , Hastuti Pramudji , Susanti Vinayanti 
Published: June 2021

AIM: This study aimed to investigate the association between two polymorphisms of thyroid hormone receptor and renin-angiotensin system (THRA C/T and angiotensin-converting enzyme (ACE) I/D) genes with hypertension in childbearing age women with hypertension.

METHODS: This was a case–control study including 35 cases and 40 matched control subjects. The case group was hyperthyroid women with hypertension while the control group was hyperthyroid women with normotension. The polymorphisms were identified by a classical polymerase chain reaction.

RESULTS: The THRA C/T gene and ACE I/D polymorphisms were not associated with the hypertension while the genotype frequencies in hyperthyroid women with hypertension were as follows: CC genotype was 25.71%, CT genotype was 54.29%, and TT genotype was 20.00%. The ACE I/D genotype frequencies in hyperthyroid women with hypertension were as follows: II genotype was 23.53%, whereas in hyperthyroid women without hypertension, the I/D genotype frequencies were CC: 7.50%, CT: 72.50%, and TT: 20.00%. There were no differences in age, thyroid-stimulating hormone, FT4, systolic blood pressure (SBP), diastolic BP between subgroups in ACE I/D, and at THRA rs-939348. There was a significant difference in the levels of FT4 concentrations in THRA rs-939348. Hypertension groups have higher SBP than controls. Genotype II had higher SBP but it was not statistically significant, while individuals with allele I had SBP higher than D allele.

CONCLUSIONS: The I allele of the ACE gene is involved in susceptibility to hypertension and polymorphism in THRA increasing concentration of FT4. There was no statistically significant difference in blood pressure between hyperthyroid women with or without hypertension.

AIM: The study aims to determine the effect of Moringa oleifera teabags on increased Hemoglobin (Hb) in adolescent girls.

METHODS: The research method used in this research was a pre-post-test one group design, a research design to determine the cause and effect or effect of an intervention. The treatment was carried out by giving M. oleifera teabags 2 times. Specifically, one sachet (3 g) in the morning and one sachet (3 g) in the afternoon, dipped in 250 ml hot water, and added two teaspoons granulated sugar. The treatment was given for 30 days.

RESULTS: An increase in the average of Hb (mean) before the intervention was 10.71 g/dl. After 15 days of the intervention, it was 11.03 g/dl. Subsequently, after 30 days of intervention, the average Hb value (mean) was 11.63 g/dl, then the p-value ≤ α, which was 0.000 (p < 0.05), and these results indicated a significant difference between Hb before and after the intervention.

CONCLUSION: There was a significant difference between Hb before and after the intervention, meaning that there was an effect of Moringa leaf teabags on the increase in Hb in adolescent females.

Published: June 2021

Introduction: To investigate the influence of secretomes from native and dexamethasone-treated adipose-derived multipotent mesenchymal stromal cells (MMSC) on the proliferation of mononuclear cells (MNCs) and on their expression of phospho-NF-κB p65 in vitro.
Materials and Methods: MMSCs were isolated from the fat of 5 healthy donors. The cells were grown in culture up to passage four, then treated with dexamethasone for 3 hours, washed off the preparations, and incubated in a serum-free medium for 48 hours. Some of the cells were not treated with dexamethasone. Supernatants from cell cultures were concentrated by ultrafiltration, standardized by the content of galectin-1, sterilized, and added to MNCs from peripheral blood of 8 healthy donors. MNCs were isolated in a Ficoll density gradient according to a standard protocol. The expression of phospho-NF-κB p65 and Ki-67 in MNCs under the influence of MMSC secretomes in isotypic and negative controls was determined on a flow cytometer.
Results and Discussion: The expression of phospho-NF-kκB p65 and Ki-67 is decreased by the MMSC secretome. At the same time, a statistically significant decrease in phospho-NF-κB p65 by 36.2% (p< 0.05) is observed when using a secretome from native cells. Ki-67 expression is reduced by 42.3% (p < 0.05) under the influence of a secretome from dexamethasone-treated MMSCs.
Conclusion: The MMSC secretome, as well as MMSCs themselves, has an anti-inflammatory effect due to the effect on the expression of the active form of NF-κB and the proliferative activity of mononuclear cells. At the same time, pretreatment of cells with dexamethasone reduces the effect on phospho-NF-κB expression and increases the inhibitory effect on MNC proliferation.

Authors: Kumar Shreya , Thiruvenkadam Swarnalaxmi 
Published: June 2021

Feature extraction is an integral part in speech emotion recognition. Some emotions become indistinguishable from others due to high resemblance in their features, which results in low prediction accuracy. This paper analyses the impact of spectral contrast feature in increasing the accuracy for such emotions. The RAVDESS dataset has been chosen for this study. The SAVEE dataset, CREMA-D dataset and JL corpus dataset were also used to test its performance over different English accents. In addition to that, EmoDB dataset has been used to study its performance in the German language. The use of spectral contrast feature has increased the prediction accuracy in speech emotion recognition systems to a good degree as it performs well in distinguishing emotions with significant differences in arousal levels, and it has been discussed in detail.<div> </div>
Early-Derived Murine Macrophages Temporarily Renounce Tissue Identity during Acute Systemic Inflammation

Published: June 2021

Abstract
In mice, a subset of cardiac macrophages and Kupffer cells derive from fetal precursors, seed the developing tissues, self-renew locally, and persist into adulthood. In this study we investigated how these cells survive acute systemic inflammation. In both tissues, early-derived subsets rapidly responded to acute systemic inflammation by assuming a temporary nonclassical activation state featuring upregulation of both proinflammatory (Il1b, Tnf, Nfkb1), and anti-inflammatory (Il10, Il4ra, Nfkbiz) genes. During this process, transcription factor genes associated with myeloid identity (Spi1, Zeb2) were upregulated, whereas those associated with tissue specificity (Nr1h3 for Kupffer cells and Nfatc2 and Irf4 for cardiac macrophages) were downregulated, suggesting that the cells reasserted their myeloid identity but renounced their tissue identity. Most of these changes in gene expression reverted to steady-state levels postresolution. We conclude that these early-derived macrophage subsets are resilient in the face of acute stress by temporary loss of adaptation to local tissue-specific niches while reasserting their generic myeloid identity.

Published: June 2021

Objective:
This observational cohort pilot study aimed to evaluate the effects of the acupuncture methods, Jiu Cang Zhen (JCZ) and Huang Guan (HG), on changes in headache intensity in an inpatient, multimodal Zurzach Headache Programme (ZHP).

Methods:
Study participants consisted of patients diagnosed with chronic headache disorder (headache ds, 30 days per month) or daily persistent headache. All patients received conventional therapies with active and passive approaches. The patient group was treated with JCZ and HG acupuncture methods, receiving a total of six to eight acupuncture sessions of 50 to 60 minutes each, during a 3–4-week multimodal ZHP at the RehaClinic Bad Zurzach. Pain intensity was quantified using a Numerical Rating Scale (NRS) before and after each acupuncture therapy session.

Results:
Ten patients were recruited, six women and four men, with a mean age of 41.7 (standard deviation, [SD] =13.9). A reduction in headache intensity was reported by all patients in each of the sessions. The average NRS for pain was 4.21 (SD = 1.44) before acupuncture and 1.24 (SD = 0.93) after acupuncture (means first by number of sessions, then per n = 10 patients). This resulted in a mean difference of 2.97 (SD = 1.04), corresponding to a standardized response mean of 2.85 (95% confidence interval: 2.11–3.60, one-tailed P < 0.001), meaning there was a large effect.

Conclusions:
This pilot study shows that JCZ and HG are suitable acupuncture methods for reducing headache intensity in the treatment of headaches. A comparison with the conventional classical acupuncture methods from the acupuncture textbook for traditional Chinese medicine students in China, exploration with a larger patient group, and prolonged monitoring of pain behavior could be foci of follow-up investigations.

Dalam dunia penerbangan banyak aspek yang mendukung untuk terjadinya suatu penerbangan yang aman dan lancar hingga dapat menghubungkan perjalanan antar pulau bahkan benua. Jika berbicara mengenai penerbangan pasti yang terlintas adalah peswat yang mengudara secara teratur di udara, namun untuk mengudaranya pesawat tersebut secara teratur perlu seorang pemandu yang memastikan kegiatan penerbangan dalam keadaan lancar dan aman. Pemandu lalu lintas udara atau air traffic controller (ATC) ialah seorang yang memastikan dan memandu pesawat saat berada di daratan maupun saat mengudara, ATC bertugas memberikan informasi yang dibutuhkan pilot, seperti informasi cuaca, navigasi penerbangan, dan lalu lintas udara. Ia juga bertugas memandu pilot untuk menaikan, menurunkan, atau membelokkan pesawat. ATC harus siap memandu pesawat dalam cuaca panas ataupun hujan sekalipun. Keadaaan cuaca dan hujan dapat sangat berpengaruh terhadap kegiatan penerbanngan. Hal ini desebabkan dari runway yang merupakan hal utama dalam suatu bandar udara. Runway tersebut digunakan untuk kegiatan take off dan landingnya pesawat. Jika hujan terjadi maka kondisi runway akan basah dan saat runway basah sangat berisiko terhadap kegiatan pesawat apalagi jika terdapat genangan air yang berada di runway. Hal tersebut dapatmengakibatkan terjadinya musibah tergelincir, maka untuk mencegah terjadinya hal tersebut perlu adanya alat standing water detector yang saat ini belum tersedia di bandar udara El Tari, Kupang. Alat tersebut digunakan untuk memberikan informasi mengenai ketinggian air di runway

Embroidery as a fundamental component of the decor of the Kalmyk costume reflects the traditions of the Mongol-speaking peoples in the Eurasian vector of their development. The study emphasizes the authenticity of the sign system of the Oirat-Kalmyk costume in the conditions of the changed habitat of the ethnic group. The integrity of spiritual and material culture, as the utilitarian and artistic basis of the applied art of Kalmykia — is the basis of the analysis in the interpretation of the material. The results of the study show a developed Central Asian artistic tradition in the processing of textiles. The traditional decoration system of the Kalmyk costume reveals the preservation of the endemic tradition and its transformed development in the new conditions of the people’s resettlement and the expansion of ethnic and cultural contacts.
Статья посвящена рассмотрению калмыцкой вышивки, выявлению предпосылок и факторов ее развития, этнических особенностей исполнения. Опираясь на совокупность художественно-выразительных средств калмыцкой вышивки, автор рассматривает золотное шитье в системе калмыцкого народного костюма сквозь призму пластического мировоззрения этноса. Вышивка как основополагающий компонент декора калмыцкого костюма отражает традиции монголоязычных народов в евразийском векторе их развития. В исследовании подчеркивается аутентичность знаковой системы ойрат-калмыцкого костюма в условиях измененной среды обитания этноса. Целостность духовной и материальной культуры как утилитарно-художественной основы прикладного искусства Калмыкии — основа анализа в трактовке материала. Результаты исследования показывают развитую центральноазиатскую художественную традицию в обработке текстиля. В традиционной системе декора калмыцкого костюма обнаруживается сохранение эндемичной традиции и ее трансформированное развитие в новых условиях расселения народа и расширения его этнокультурных контактов.
