Authors: Li Ruihan , Han Aojing , Hu Qilin , Liang Wei
Published: August 2023

We aimed to explore the associations of neonatal hypocalcemia with neonatal vitamin D deficiency and maternal vitamin D deficiency. A comprehensive systematic literature search using PubMed and web of science was performed for relevant articles from inception to February 17th, 2023. We used odds ratio (OR) and 95 % confidence interval (CI) as effect sizes for our meta-analysis. Publication bias was evaluated using funnel plot, Begg’s test, and Egger regression test. All the statistical analyses were performed using Stata 14.0. A total of 11 studies were included and analyzed, including 452 newborns with hypocalcemia and 2,599 newborns with normal serum calcium level. Our research results revealed that vitamin D deficiency in newborns may be related to the higher prevalence of hypocalcemia (OR: 2.87, 95 % CI: 1.17–7.04). In addition, maternal vitamin D deficiency might also be a risk factor for neonatal hypocalcemia (OR: 7.83, 95 % CI: 3.62–16.92). There was a significant correlation between vitamin D deficiency and neonatal hypocalcemia.This meta-analysis indicates that newborns with vitamin D deficiency have a higher risk of hypocalcemia, and maternal vitamin D level play a crucial role in this association. Vitamin D supplementation may have a positive effect in reducing the prevalence of neonatal hypocalcemia.

Authors: Wierenga Michiel , Bogers Marion , Beeres Robert , Bollen Myriame
Published: August 2023

By offering a comprehensive insight into the burden sharing behavior of states contributing to the MINUSMA peacekeeping mission, this paper contributes to the growing literature on burden sharing during specific crisis response operations. Three fairness principles (i.e. equality, equity and exemption) are applied to present an inclusive view on how burden sharing evolves. We find proximity to serve as a paramount motivation to contribute to the mission. As compared to advanced states, low income developing countries both deployed most troops to MINUSMA and were overrepresented in Mali’s most dangerous areas. The highest troop contributing countries have been compensated financially and advanced economies provided the financial and technical means.
Chaotic dynamics of an extended Duffing-van der Pol system with a non-smooth perturbation and parametric excitation
Authors: Hu Sengen , Zhou Liangqiang
Published: August 2023

Chaotic dynamics of a fifth-order extended Duffing-van der Pol system with a non-smooth periodic perturbation and parametric excitation are investigated both analytically and numerically in this paper. With the Fourier series, the system is expanded to the equivalent smooth system. The Melnikov perturbation method is used to derive the horseshoe chaos condition in the cases of homoclinic and heteroclinic intersections. The chaotic features for different system parameters are investigated in detail. The monotonic variation of the coefficients of parametric excitation and non-smooth periodic disturbance is found. With numerical methods, we validate the analytical results obtained by Melnikov’s method. The impact of initial conditions is carefully analyzed by basins of attraction and the effect of non-smooth periodic disturbance on the basin of attraction is also investigated. Besides, the effect of different parameters on the bifurcation pathway into chaotic attractors is examined.

Authors: Othero Marilia Bense
Published: August 2023

An orthosis is a rehabilitation device applied to a body segment (with one or more joints), whose function is to stabilize, immobilize, prevent, or correct deformities, and maximize patient functionality.However, in end-of-life care and palliative rehabilitation, changes are needed for orthosis prescription, once the main objective is comfort and symptom management. The aim of this article is to present a specific model of high-density foam orthosis developed in a Brazilian hospice for terminally ill patients, and discuss about the roles and strategies in palliative rehabilitation. This orthosis model is proposed for patients with advanced disease and no prognosis of functional recovery. It is manually made with high-density foam, cotton fabric, board velcro, EVA (ethylene vinyl acetate), hot glue, folding or electric knife. The foam is cut with the folding knife according to the required orthosis model, then covered with fabric and EVA. Board velcro is added to place the device on the patient. Positive results can be described: adherence to the use of the orthosis, minimal discomfort reported, muscular relaxation/tonus regulation, pain management and reduction of edema. Rehabilitation is an integral part of Palliative Care, and in case of terminally ill patients, comfort is the main objective of the care plan. The intervention of Occupational Therapy and the use of foam orthosis is an important strategy to achieve this goal.

Published: August 2023

The face is arguably the most important factor in a person's physical appearance, including the smile. In facial aesthetics, the initial objective is to determine the facial type, in order to promote balance and harmony between the hard tissues (teeth and bones) and soft tissues that make up the face. the lateral teleradiographs and the tracings on the teleradiographs performed, the so-called cephalometric analysis, are the most used to study the contour, the relationship between the hard tissues and the soft tissues, and thus, determine the best treatment. Currently, for the aesthetic improvement of the nose, improving its dimensions and proportions, we have the Perfect Nose® technique, a registered, promising and exclusive technique, which, in addition to improving the aesthetics of the nose, can also promote functional improvement. Thus, the objective of this work was to subjectively evaluate, through a comparative study between Subjective Facial Analysis (by means of photography) and Cephalometric Analysis of Soft Tissues (ACTM), the lip repositioning resulting from the Perfect Nose® technique.
The “Magic Neck Lifting”- a new technique for neck rejuvenation with barbed tensor thread
Authors: Fechine Feitosa Roney Gonçalves
Published: August 2023

In recent years, the utilization of barbed tensor threads has surged in popularity as a means of rejuvenating the face, particularly in cheek rejuvenation. However, when it comes to neck rejuvenation, there is a scarcity of comprehensive techniques and explanations regarding the use of barbed sutures. This innovative approach employs minimally invasive methods to elevate and tighten the neck skin by employing barbed threads. These threads are equipped with small barbs that securely grip and uplift the tissue. Through the careful insertion of these threads using tiny needles and strategic placement, the desired lifting effect is achieved. Due to its minimal invasiveness, minimal downtime, and absence of scarring, it has become a favored option for individuals seeking a non-surgical alternative to traditional neck lifts.

Implementability of the intervention model: microbiota-gut-brain axis in Colombia
Authors: Igua Ropero Diana María
Published: August 2023

According to the World Health Organization (WHO), worldwide, the most prevalent pathologies that urgently need intervention are cardiovascular diseases (CVD), mental disease and, due to their health burden, neoplasms. These pathologies share a common origin associated with dysfunction of the gut-brain-nutrients-microbiota-metabolism (GBNM2) axis. Therefore, it is necessary to develop effective health care models that prevent GBNM2 axis dysfunction based on strategies such as primary health care (PHC), to promote and maintain health, intervene in risk factors that limit capital in health and prevent the appearance of chronic non-communicable diseases, which lead to these outcomes. However, countries have social determinants of health that limit its implementation, such as globalization, cultural conditions, low income, low coverage in public health policies and human talent. In this sense, the model of the GBNM2 axis and the intervention of the 7 zones proposed by Camacho is a reference to address some risk factors that lead to this problem and an alternative to encourage its applicability. This article explores the facilitators, barriers, and implementation of the model based on the theory of social determinants in the Colombian health system, led by specialties such as family medicine.
Can gene expression delay aging and increase longevity?
Authors: Sofra Xanya
Published: August 2023

The reality of interacting genes and proteins is vastly complex and intricate with many unknowns which currently prevent us from solving the anti-ageing equation in terms of gene expression. Molecular studies involving genome modification should take into consideration the importance of apparently opposing genes and proteins which when seen as a whole, can orchestrate an optimal systemic balance. Gene expression is often a double-edged sword with positive effects turning negative when a particular gene is overexpressed. For this reason, the US National Academy of Sciences and the National Academy of Medicine have placed stringent restrictions on the promising genome editing methods to be used only for the specific DNA sequence associated with a transmissible genetic disease. Rejuvenation as a result of gene expression is still an open area of research with studies that have either been limited to in vitro research or clinical studies claiming success based on a limited perspective that selectively emphasises the benefits of certain genes while leaving the negative outcomes in the shadows of their silence. For example, some investigators relate the presence of ZMPSTE24, IGF1R, NGF4, EEF2, EIF4FBP1 CCL18, and other genes with “rejuvenation,” selectively focusing on potential benefits while ignoring the involvement of some of these genes in malignancies and inflammation. Well-controlled gene expression molecular experimental studies with mechanotherapy and effortless exercise have limited themselves to the observation of increased slow skeletal genes associated with muscle growth that do not present any adverse side effects. Overall, exercise and nutrition are still the safest and most ethical methods of gene expression at least until genome editing can be extended to delaying ageing, in the near or distant future. As observed in the research analysing gene expression as the result of different types of exercise, inflammatory events are counterbalanced by antagonizing anti-inflammatory ones. This signifies optimal biological homeostasis because health depends on the harmonious interaction of opposite processes levelling and stabilizing each other. Exercise modalities and lifestyle are still representing the cornerstone of delaying ageing and the most riskless method of increasing longevity by triggering processes that balance each other.
Curcumin nanosystems as prospective antiviral alternatives: their stability in an aqueous ChitosanTergitol-15-S-7 system

Published: August 2023

Curcumin, the primary curcuminoid component of turmeric (Curcuma longa L), has been shown to have powerful antibacterial properties, inhibiting the growth of a wide range of infections. The research presented here focuses on current Curcumin nanosystems investigations to aid in the progress of curcumin and its derivatives as comprehensive antiviral therapies. The breakdown rates of curcumin were determined using spectrophotometry, which allowed the compound's stability to be determined using chitosan and Tergitol-15-S-7. Tergentole 5 was also utilised as a surfactant. Hydrophobic contacts, hydrogen bond formation, and electrostatic interactions are examples of exothermic interactions between curcumin and chitosan. Tergitol-15-S-7 impacts the interaction between curcumin and chitosan in large doses, according to an examination of absorption and fluorescence patterns at a physiological pH (7.4). The apparent binding constants and distribution of curcumin within the interior of chitosan have been demonstrated using the fluorescence quenching method. Fluorescence quenching techniques revealed that curcumin distribution in colloidal chitosan solution is not uniform. The hydrophobic interior of chitosan is mostly constrained to its cationic centres, which contain curcumin. Nano curcumin supplementation decreased inflammation, respiratory function, clinical symptoms, and sequelae in people with COVID 19 and other viral infections.

Authors: Cheepsattayakorn Attapon
Published: August 2023

A comprehensive search was carried out in mainstream bibliographic databases or Medical Subject Headings, including ScienDirect, PubMed, Scopus, and ISI Web of Science. The search was applied to the articles that were published between 2021 and mid-2023. With strict literature search and screening processes, it yielded 8 articles from 349 articles of initial literature database. A number of previous studies demonstrated that KTRs or non-KTRs with renal failure markedly reduced vaccine response, whereas adaptive protocols of mRNA COVID-19 vaccination or alternative adjuvant vaccines is now not known yet. A recent study revealed that acute kidney injury and mortality could be caused by SARS-CoV-2 (COVID-19) around 50 % and 23 % of the infected KTRs. No different post-V4-T-cell response and anti-S antibody levels were detected by vaccine type combination (ChAdOx1 plus BNT162b2) among participants, whereas post-V3 seropositivity demonstrated more anti-S antibody levels if administered with BNT162b2, in comparison with ChAdOx1. In conclusion, among the immunocompromised population, including KTRs, DPs, PDs, at least three doses of mRNA-COVID-19 vaccination was recommended to be the preparation of choice. Withdrawal of the immunosuppressants in KTRs and immunocompromised individual’s prior COVID-19 vaccination and at least third dose of mRNA-COVID-19 vaccination should be performed.

Gums Arabic (GA) and Xanthan (GX) are natural polysaccharides that can be extracted by natural means for applications, such adsorption of pollutants. Structural modifications such as carboxymethylation on bio-adsorbent materials, can be performed to improve its adsorptive properties. Development of polymeric nanoparticles is an economical and favorable option for the adsorption of Congo red dye, which has high toxicity and is resistant to traditional removal processes. In this work, it was developed nanoparticles (NPs) of natural GA (NPGA) and GX (NPGX) and their carboxymethylated forms (NPCMGA and NPCMGX) aiming to evaluate the adsorption of Congo red (CR) dye. NPs are sized from 133 to 1099 nm at an average zeta potential of -13 mV, suggesting stability to absorb dyes. NPGX and NPCMGX absorbed a substantially higher amount of dye than the other NPs. The kinetic studies showed that adsorption process follow pseudo-second order model, suggesting that chemisorption control the process, and the isotherm test revealed that samples fit Langmuir model, with a homogeneous adsorption profile for the two carboxymethylated samples with a maximum adsorption capacity of 182,82 mg/g for NPCMGX and 757,58 mg/g for NPGX. These findings indicate that NPs from Xanthan Gum can be used for removal CR in contaminated water and wastewater.

Objective: It aimed to determine the incidence of different pathology among the hysterectomy specimens and to correlate that with the clinical picture of patients’ presentation. Design: A retrospective study, it is the first audit of histopathological findings of laparoscopic hysterectomy specimens at Noble’s Hospital. Methods: It included 101 consequent specimens of laparoscopic hysterectomies done at the department of Obstetrics and Gynaecology, Noble’s hospital between 2017 and 2020. The clinical picture of patients and the histopathological findings of samples were recorded and analysed. The histopathological diagnosis divided the specimens into seven groups, no pathology, adenomyosis, adenomyosis and leiomyoma, leiomyoma, adenomyosis and endometriosis, endometriosis and malignancy. The clinical picture included all types of bleeding as menorrhagia, post coital bleeding, intermenstrual bleeding and perimenopausal bleeding, all types of pain as dyspareunia, dysmenorrhea, lower abdominal pain and colicky pain. Histopathological findings include gross picture and microscopic analysis of endometrium and myometrium as well as the uterine weight. Results: Adenomyosis alone or with other pathology was the commonest finding (54.5%) while adenomyosis as a sole pathology was found in 22.8%. It was significantly higher than figures reported from the UK and worldwide. Incidence of fibroid as a sole pathology or in combination with other pathology was 44.6%, this was compatible with results reported before. The pain was not associated with adenomyosis in this study. The bleeding was the presenting symptom of both adenomyosis and fibroids. Conclusion: The higher incidence of adenomyosis among this specimen and the absence of pain as a presenting symptom may be a genuine finding but most probably indicate the specimen included a larger number of mild and early presentations. It will be useful to do a prospective study of a larger number to correlate the degree of the invasion of the adenomyosis to the myometrium to the clinical picture.

The unique temperature-induced color changing properties of thermochromic materials make them of significant interest for applications in aerospace, anti-counterfeiting technology, construction, defense, drugs & pharmaceuticals, electronics, energy, food & agriculture, maintenance of infrastructure, materials processing & storage, military technology, optoelectronics, packaging, sensors, smart displays, textiles, thermal storage and transportation. Thermochromism occurs due to the following characteristics: (a) phase transitions in a compound (e.g. leuco dyes); (b) changes in ligand geometry or the number of solvent molecules in the coordination sphere (e.g. transition metal complex that derives its color from crystal field effects) and (c) complex factors in multicomponent mixtures. Thermochromic materials can be divided into several categories depending on their material properties and operating conditions. In recent years, numerous techniques have been used to synthesize thermochromic materials for a variety of purposes and applications. This review summarizes the various mechanisms of thermochromism, their classification, preparation and applications and discusses future development trends.

Propagation of solar disturbances and heliospheric storms
Authors: Akasofu Syun-Ichi
Published: August 2023

In this paper, we review solar disturbances (solar flares) and their propagation towards the earth and to the heliosphere. For solar flares, we consider that a photospheric dynamo supplies the power and that high speed streams are caused by the basic solar wind (modified by the solar magnetic field), not from coronal holes. These new views allow us to predict the occurrence of solar flares and the 27-day recurrent storms more accurately than in the past. It is suggested that the explosive aspect of solar flares, the phenomenon, called ‘diparition brusques (DB)’, is the source of coronal mass ejections (CMEs)/magnetic clouds (MCs) and of heliospheric disturbances, namely heliospheric storms. It is also suggested that some CMEs have a magnetically helical structure, which are rooted at the sun. For the inner heliospheric storms, a simple method, called the HAF method, is used to study the propagation of solar disturbances and tested by various simultaneous space probes, such as IMP, HELIOS A, and B for the inner heliosphere. For the middle heliosphere, the same method is tested at a distance 7 au with the Pioneer 11 data; the result is satisfactory. The method is further extended to 100 au in an early 2004; thus, it is possible to envisage the whole heliospheric disturbances over 200 days.

Published: August 2023

In this paper we study rotational dynamics of a ball lightning. Cases of deceleration and acceleration of rotation are described, which suggests that the cause of rotation may be the internal movement of elements of the ball lightning core. A model for particles separation from the surface of a rotating ball lightning is presented. It is also shown a qualitative explanation of the interaction of rotational moments of the ball lightning core elements, causing a change in the rotation speed of the ball.

Mesenchymal stem cells (MSCs) have become an effective tool for treating immune-related diseases due to their multilineage potential and immunomodulatory capabilities. One of the main factors contributing to their immunomodulatory capabilities is the IDO cascade, which was chosen as the main subject in this research. The IDO-Kyn-AHR-CYP cascade was chosen to evaluate the immunomodulatory properties of treated MSCs, with expression levels of the key gene IDO (indoleamine 2,3-dioxygenase) selected as the screening criterion. Cultured human umbilical cord MSCs (hUC-MSCs) were treated with different natural bioactive compounds. Preliminary results indicated that Rubiadin-3-methyl ether, an anthraquinone derivative isolated from the roots of Morinda longissima, was able to significantly induce IDO2 expression in UC-MSCs but not CYPs. This is the first study to show a link between Rubiadin-3-methyl ether and IDO2 in hUC-MSC. More research is needed to determine whether human UC-MSCs primed with Rubiadin-3-methyl ether have any significant benefits for treating immune-related diseases and disorders.

Drought stress is one of the most detrimental abiotic stresses that has undeniably negative impacts on the growth and development of soybean plants. According to previous studies, cytokinin-related genes have been proposed to play vital roles in plant response and adaptation to drought stress. From a report, the soybean gene GmCKX13 encoding cytokinin oxidases/dehydrogenase was shown to be upregulated under drought condition. In this study, GmCKX13-overexpressing soybeans were used to evaluate the involvement of GmCKX13 in plant adaptation to water scarcity condition. According to the results, the introduction of GmCKX13 transgene conferred the transgenic plants enhanced drought tolerance capacity, which was featured with higher drought-tolerant index and better water retaining in the tissue under water deficit condition in comparison with the wild-type plants. Additionally, the transgenic soybean plants also showed lower level of intracellular hydrogen peroxide content, which was in agreement with the stronger activities of hydrogen peroxide-scavenging enzymes - catalase and peroxidase. These results indicate a promising application of GmCKX13 in enhancing antioxidant defense system against oxidative damage caused by drought stress in plants. Taken together, therefore, it is suggested that GmCKX13 may contribute to soybean adaptability to drought stress, which would result in crop yield improvement.

Drug-Loaded Albumin Nanoparticles: A Short Review
Authors: Samaddar Soma , Chakraborty Ankshumita
Published: August 2023

Albumin is derived from plasma and it is the most abundant protein in plasma, which is an ideal material for the preparation of nanoparticles because of its good biocompatibility, noncytotoxicity, nonimmunogenicity, biodegradability, and so on. Albumin amplifies the targeting of drugs,
brings down the deadliness of free drugs, and amplifies water solubility of free drugs. The methods of preparation of albumin nanoparticles exhibit benefits and drawbacks due to contrasts in principles and preparation conditions.

Resumo Objetivo: Analisar os efeitos da resiliência psicológica e das atitudes gerenciais (envolvimento no trabalho e comprometimento com as metas orçamentárias) na relação entre participação orçamentária e desempenho gerencial. Originalidade/valor: A pesquisa inova ao fornecer evidências dos efeitos cognitivos da resiliência psicológica, dos efeitos afetivos do envolvimento no trabalho e do comprometimento com as metas orçamentárias na relação entre participação orçamentária e desempenho gerencial, sendo essa a lacuna teórica explorada. Design/metodologia/abordagem: Realizou-se uma pesquisa descritiva, de levantamento e quantitativa por meio de modelagem de equações estruturais (MEE), em uma amostra composta por 251 profissionais controllers de empresas da Região Sul do Brasil. Resultados: Os resultados revelam que as variáveis intervenientes (resiliência psicológica e atitudes gerenciais) exercem influência positiva na relação testada. Os achados demonstram que a participação orçamentária influencia o desempenho gerencial por meio dos efeitos cognitivos da resiliência psicológica somados aos efeitos afetivos do comprometimento com as metas orçamentárias. O envolvimento no trabalho potencializa os níveis de resiliência psicológica e apresenta efeitos positivos no desempenho gerencial. Assim, pode-se concluir que a configuração orçamentária exerce influência nos níveis de resiliência dos controllers e contribui para o seu comprometimento com as metas orçamentárias, uma vez que desencadeia reações cognitivas e afetivas que elevam o desempenho gerencial.
L’ethnogenèse d’un État-nation
Authors: Borsi-Kálmán Béla
Published: August 2023

Le présent ouvrage se propose de mettre en lumière deux phénomènes historiques, lesquels, avantageusement complémentaires, ont contribué au succès de l’Etat roumain moderne.

D’une part, du point de vue de l’élite, l’histoire des Phanariotes (leur parcours triomphant aux XVIIe-XVIIIe siècles, dans le cadre de l’Empire ottoman – y compris dans les principautés de Valachie et Moldavie –, jusqu’à la chute brutale de 1821) est à l’origine des mentalités du milieu social et culturel où plongent les racines de la pensée politique roumaine, cette “façon politique” à la fois souple et pragmatique, et surtout formidablement efficace. Le berceau de la fabrique politique et diplomatique roumaine a été promené dans les jardins de Constantinople, où les contraintes du système turco-phanariote ont développé les capacités intuitives d’une future élite particulièrement apte à la manoeuvre et à la survie.

D’autre part, d’un point de vue social plus étendu, de larges vagues de migrations aroumaines – pour partie bulgares, macédo-slaves, albanaises –, en provenance d’une péninsule balkanique baignant dans la culture grecque moderne, se sont intégrées, sans encombre, à la bourgeoisie en cours de formation dans les Principautés, et cela en raison même d’une osmose familière entre la parenté ethnique-linguistique roumaine et le substrat culturel grec, fondement de leur future assimilation à l’identité roumaine.

L’optimisation réciproque des deux phénomènes repose sur leur commune combinaison d’éléments roumains et grecs, favorisée par les conditions historiques prévalant au sommet de l’Empire ottoman et dans la vie des populations de la péninsule balkanique. À ces circonstances favorables, ajoutons encore l’excellente capacité d’accueil des Principautés, encouragée par la thèse de l’origine daco-romaine embrassée par l’intelligentsia roumaine de Transylvanie et diffusée au-delà des Carpathes.
