Authors: Bayat Amir-Hossein , Pownall Madelleine , Falahati Mohsen
Published: March 2023

Background: Hypertension (HTN) is one of the most dangerous chronic diseases, and it is always considered one of the most common causes of mortality and disability all over the world.
Methods: In this research, 3147 files of periodic examinations were studied. They were from various industries located in Iranian Kaveh Industrial Zone in 2018. The principal aim of this cross-sectional study was to elucidate the prevalence of HTN on a great number of people working in this industrial zone. The plan was to predict the exact effect of demographic factors, such as income, work experience, age, sex, BMI, etc. on blood pressure and, elucidate whether these variables make people vulnerable to HTN.
Results: According to this research, around 5% of the subjects were hypertensive. Results showed that there was a significant relationship between HTN demographic characteristics (p< 0.001). Fisher test demonstrated a significant relationship between age and HTN (p< 0.001). The lowest percentage of accidents belongs to workers with 25-30 years of experience. Chi-square test showed no significant relationship between hypertension, and marital status and sex. Based on linear regression analysis, it was shown that the factors identified in this study, 23.3% predict HTN (r: 0.233). Moreover, BMI factor is the most important predictive variable (B=0.148) among the variables.
Conclusions: Dramatic role of predictive factors and bringing out the new strategy to deal with HTN in the industrial workplace should be seriously considered. It will improve health level of workers as they spend a lot of time in factories.

Authors: Hasanah Noor , Jannah Raudatul
Published: March 2023

Gender discrimination has been around for a long time. Interestingly in Banjar, at the elite level, women are actually entrusted to play an active role in the public sphere. Such as an intellectual actor in the development of Islamic knowledge and as a leader. This role was played by Fatimah, Putri Mayang Sari, Nyai Kumala Sari, and Ratu Zaleha. Everyone has their own role in their era. The writing of this article uses the library method, by applying 4 steps, that are heuristics, verification or source criticism, interpretation, and historiography. The results of the study indicate that historically Banjar women, at the elite level, have had opportunities and open roles to be able to contribute to the public sphere. The implementation of this role relies on clarity of thought, flexibility of knowledge, courage to take risks, and the ability to read situations and understand social conditions. Thus, the role and contribution of women in various fields cannot be denied and underestimated. The role and contribution of Banjar women needs to be disclosed more broadly, because studies related to this matter are still limited.
Membangun Super Enkripsi untuk Mengamankan Pesan
Authors: Agustina Laura , Sujarwo Imam , Khudzaifah Muhammad
Published: March 2023

The issue of message security or an information is very important. A science that studies about securing the confidentiality of messages using passwords is called cryptography. To enhance security, two algorithms are combined to secure messages. Super encryption is a concept that uses a combination of two or more substitution and permutation (transposition) cryptography techniques to obtain an algorithm that is more difficult to crack. The first thing to do is to encrypt the message using a substitution technique (Cipher Substitution), then re-encrypt it using a permutation technique (Cipher Transposition). In this study, two cryptographic algorithms will be combined to build super encryption using the Vigenere Cipher and Bifid Cipher algorithms to secure messages. The message encryption process is using the Vigenere Cipher algorithm for the first encryption process, then continued using the Bifid Cipher algorithm for the second encryption process. The encryption process is done the other way around, starting from the back of the encryption process. The combination of these two algorithms results in more secure message security.
Asymmetric Pass-through Effects of Oil Price Shocks and Exchange Rates on Inflation in Nigeria: Evidence from a Nonlinear ARDL Model
Authors: Sa’ad Suleiman , Usman Ali Baba , Omaye Solomon Ochada , Yau Hamisu
Published: March 2023

This paper employs the linear autoregressive distributed lag (ARDL) model, the asymmetric nonlinear ARDL (NARDL) model developed by Shin, et al (2014) to examine  the asymmetric effect of oil price and exchange rates pass-through on inflation in Nigeria over a period of 1970 to 2020. The result of the asymmetric test revealed the existence of asymmetries among the variables of the study, suggesting that there is a nonlinear interaction among the variables used in the study. This validates the choice of a non-linear ARDL model for the study. Results of the long-run estimates show that rising (Positive) oil price shocks have a greater impact on inflation than falling (negative) oil price shocks. Furthermore, it is evident from the result that the depreciation of the exchange rate has a much and significant effect on inflation than the appreciation of the exchange rate in Nigeria. However, a rising interest rate increases inflation by 0.84 per cent while a falling interest rate increases inflation by 0.85 per cent. This implies that the effect of negative interest rate on inflation is higher than its positive effect on inflation, though, by a smaller amount of about 0.01 per cent. Again, the short-run dynamic model revealed a high speed of convergence of more than 90% from the short-run disequilibrium. During the study period, the oil price fluctuations showed a significant and incomplete pass-through to both exchange rates and inflation in Nigeria. Moreover, the results suggest that positive oil price changes have a larger impact than the negative ones, that the effect of an oil price shock on inflation and exchange rates is larger in the long-run than in the short-run, and that there is incomplete pass-through effect of oil price on domestic inflation and exchange rates. Based on the findings, the study recommends policies that set oil prices and exchange rates within reasonable limits to check inflation in Nigeria and should diversify its economy as well as withdraw the current subsidy regime completely.

Published: March 2023

The high catabolism and inflammatory responses due to the burn injury can affect the increase of free radicals resulting in oxidative stress condition that delays the healing process of wounds. Providing protein can help to improve protein loss during catabolism, as for antioxidants, they prevent the occurrence of oxidative stress situation. One product of protein and antioxidants source that have been developed is a liquid food formula made from Catfish and Moringa flour which were processed using nanotechnology. This study aims to analyze the effect of liquid food formula made from Catfish and Moringa flour processed using nanotechnology on Sprague Dawley rats with burn injury, especially on malondialdehyde levels and reduction in wound area. The design of this study was an experimental study with 6 experimental groups, namely rats with aquadest intervention (K), 15% liquid food formula (MCB 15), 30% liquid food formula (MCB 30), 15% nano liquid food (MCN 15), and 30% nano liquid food (MCN 30) that given for 14 days. The One Way ANOVA test indicated that there was no significant difference in malondialdehyde levels among all experimental groups. However, the highest decrease in malondialdehyde levels occurred in the MCN 30 group. Moreover, the MCN 30 group also showed the highest reduction in the wound area and was significantly different from the control group, MCB 15, MCN 15, and MCK 30, but didn’t show a significant difference from the MCB 30 group based on the One Way ANOVA test and a further test of Duncan.

Stunting in rural areas tends to be higher than in urban areas. This study aims to determine the risk factors for stunting in rural areas in Bali. The analysis carried out is a further analysis of the 2018 basic health research (RISKESDAS 2018). The independent variable was the stunting status of children, which was determined based on the height-for-age index (HAZ). The independent variables consist of socio-demographic; the environment; and health services factors. The relationship between variables was analyzed by logistic regression method. Estimation of the proportion of stunting that can be prevented using Population Attributable Fraction (PAF) analysis. RISKESDAS 2018 data shows that the percentage of stunting in rural Bali is 29.3% higher than urban areas which is only 19.1%. The results of logistic regression analysis showed that under-fives weighing less than 8 times/year were at risk of stunting by 2.02 times compared to the other. PAF analysis shows that 3.5 percent of stunting under five in rural areas can be prevented by Monthly Weighing for children under five years old. Monthly Weighing in rural Bali through the Integrated Service Care (POSYANDU) is one of the efforts to prevent stunting children and monitor their the growth and development early.

‘Please Don’t Go Yet’: The Voice and Texture of Indian Women’s Campaign Rhetoric
Authors: Chakravarty Subhasree
Published: March 2023

724 women candidates from India campaigned for their parties in the lead up to the parliamentary elections of 2019, and yet none of them were appraised for their oratorical skills. The absence of attention on how and what women say during their political campaigns is in keeping with a widespread apathy towards women’s rhetoric in public discourses in India. Could that be the reason why electoral participation of women in India is alarmingly low and uninspiring? This article explores the gendered life of political speeches in India and the specific conditions within which the speeches of women candidates are assessed and promoted. To that end, the speeches of three political candidates are analysed, revealing an exhilarating battle of campaign rhetorics fraught with language restrictions and gender dynamics. Each of these speakers showcase a personal, idiosyncratic yet nifty tradition of political speeches through their use of domestic idioms, imagery, satire, and other feisty rhetorical claims. Most significantly, their speeches were covered by many media, catapulting to the forefront the so far neglected genre of women’s political speeches. Although refreshing, it is still an uphill battle for the candidates, as they establish themselves as rhetors on their own terms.
Shaheen Bagh (2021): Gender, Affects, and Ita Mehrotra’s Graphic Narrative of Protest
Authors: Mitra Pujarinee
Published: March 2023

Ita Mehrotra’s journalistic memoir, Shaheen Bagh: A Graphic Recollection (2021), through the graphic narrative medium, facilitates a reading of the Shaheen Bagh protests in India, particularly those in Delhi, as pivoting on affective strategies. This article argues how the women of Shaheen Bagh in Delhi mobilised affects primarily through the following activities – sharing food, singing songs and the display of artwork. The article explores: What role does the graphic narrative genre of Mehrotra’s book play in the representation of affective strategies used in the Shaheen Bagh protests? And since Shaheen Bagh was considered remarkable because the organisers were Muslim women (Verde and Kumar, 2020, n. p.), how does the study of gender and ethnicity in relation to affective strategies contribute to this proposed reading? This article is situated within the intersecting discourses of South Asian Feminisms, Contemporary South Asian literature, and Affect Theory.
Dance, Gender, and Activism in Pakistan: Interview with Performer-Activist Sheema Kermani
Authors: Basu Priyanka , Kermani Sheema
Published: March 2023

Sheema Kermani (1951-) is a performer and activist based in Karachi, Pakistan. Through her organisation, Tehrik-e-Niswan she has worked towards raising awareness of violence against women and women’s empowerment. Tehrik-e-Niswan is a cultural organisation invested in social justice through the arts. As a dancer and theatre actor, Sheema Kermani uses her training, choreography, and pedagogy to foreground the activist potential of performing arts. Scholarship on dance and political activism within the larger global context (for example in South Africa and New Zealand) have focussed on dance’s potential ‘to further social justice and compassionate communities’ (Shapiro, 2013: 15) and its power ‘to envision, move and create change.’ (Shapiro, 2016: 3) Within the contexts of the UK and USA, scholarship on dance and protest have encompassed historical enquiries (Mills, 2021), politics of representation, place, and identity (Prickett, 2013) and embodied choreographies of protest (Foster, 2003). In the South Asian context, dance as counter-hegemonic to communal politics have informed the works of artist-activist, Mallika Sarabhai in India (Grau, 2007). This interview with Sheema Kermani follows the existing strands of research on global dance and activism by focussing specifically on Pakistan. Sheema Kermani talks about her own dance pedagogy in dance and art history, her formative years in the UK and the influences of feminist and Marxist movements, and her continuing work for social justice in Pakistan in the wake of rising religious fundamentalism, gender atrocities, forced migrations and climate crisis.

Published: March 2023

Soil-borne beneficial microbes establish symbioses with plant hosts, and play key roles during growth and development therein. In this study, two fungal strains, FLP7 and B9, were isolated from the rhizosphere microbiome associated with Choy Sum (Brassica rapa var. parachinensis) and barley (Hordeum vulgare), respectively. Sequence analyses of the internal transcribed spacer and 18S ribosomal RNA genes combined with colony and conidial morphology identified FLP7 and B9 to be Penicillium citrinum strains/isolates. Plant-fungus interaction assays revealed that isolate B9 showed significant growth promotion effects in Choy Sum plants cultivated in normal soil, as well as under phosphate-limiting conditions. In comparison to the mock control, B9-inoculated plants showed a 34% increase in growth in aerial parts, and an 85% upsurge in the fresh weight of roots when cultivated in sterilized soil. The dry biomass of such fungus-inoculated Choy Sum increased by 39% and 74% for the shoots and roots, respectively. Root colonization assays showed that P. citrinum associates directly with the root surface but does not enter or invade the root cortex of the inoculated Choy Sum plants. Preliminary results also indicated that P. citrinum can promote growth in Choy Sum via volatile metabolites too. Interestingly, we detected relatively higher amounts of gibberellins and cytokinins in axenic P. citrinum culture filtrates through liquid-chromatography mass-spectrometry analyses. This could plausibly explain the overall growth induction in P. citrinum-inoculated Choy Sum plants. Furthermore, the phenotypic growth defects associated with the Arabidopsis ga1 mutant could be chemically complemented by the exogenous application of P. citrinum culture filtrate, which also showed accumulation of fungus-derived active gibberellins. Our study underscores the importance of transkingdom beneficial effects of such mycobiome-assisted nutrient assimilation, and beneficial fungus-derived phytohormone-like metabolites in induction of robust growth in urban farmed crops.

Published: March 2023

To prolong the fatigue life of a product handled by machine, parametric accelerated life testing (ALT) is mentioned as an organized technique to pinpoint design flaws and minimize fatigue-connected failures. It requires (1) an ALT procedure, (2) fatigue model, (3) parametric ALTs with adjustment, and (4) an approximate of whether present product complete the BX life. The use of a quantum-transported time-to-failure archetype and a sample size are advised. The improvements in the reliability of a refrigerator ice-maker, comprising an auger motor with bearing, were utilized as a case investigation. In the 1st ALT, a steel rolling bearing cracked due to repeated loads under cold circumstances (below −20 C) in the freezer compartment. The bearing was altered by adjusting the matter from AISI 52100 alloy steel with 1.30-1.60% chromium to lubricated sliding bearing with sintered and hardened steel (FLC 4608-110HT) because of its high fatigue strength at lower temperatures. In the 2nd ALT, a helix made of polycarbonates (PCs) fractured. As an adjustment, a reinforced rib of the helix was thickened. As no troubles in the 3rd ALT occur, the lifetime of an ice-maker was proved to be B1 life 10 years.

Authors: Yao Yikun , Chen Jiajun , Niu Rong , Zhao Zhenxin , Wang Xiaomin
Published: March 2023

The emergence of various electronic devices and equipment such as electric vehicles and drones requires higher energy density energy storage devices. Lithium-sulfur batteries (LSBs) are considered as the most promising new generation energy storage system owing to high theoretical specific capacity and energy density. However, the severe shuttle behaviors of soluble lithium polysulfides (LiPSs) and the slow redox kinetics lead to low sulfur utilization and poor cycling stability, which seriously hinder the commercial application of LSBs. Therefore, various catalytic materials have been employed to solve these troublesome problems. High entropy materials (HEMs), as advanced materials, can provide unique surface and electronic structures that expose plentiful catalytic active sites, which opens new ideas for the regulation of LiPSs redox kinetics. Notwithstanding many instructive reviews in the land of LSBs, while this review aims to offer a complete and shrewd summary of the current progresses in HEMs-based LSBs, including in-depth interpretation of design principles and mechanistic electrocatalysis functions as well as pragmatic perspectives.

Authors: Iliadou Eleftheria , Giannopoulou Joanna , Bousi Vasiliki , Papathanasiou Ilias , Bibas Athanasios
Published: March 2023

OBJECTIVE: This study aimed to investigate the vocal health literacy level and attitudes of professional and amateur performing artists in Greece and identify possible gaps and limitations that should be addressed in the future. METHODS: This mixed-methods study took place in two successive
stages. The first stage involved 4 focus groups with professional and amateur actors and singers. The focused discussions of this stage, which were moderated by one otolaryngologist and one speech and language therapist, provided necessary information for the design of the structured questionnaire
used during the second stage of the study (online survey). The online questionnaire included questions about responders’ knowledge and attitudes of vocal health. Although not compulsory, the Greek version of the Singing Voice Handicap Index (SVHI) was also part of the online survey.
RESULTS: The online questionnaire was validly answered by 305 respondents during a 10-month period (May 2020 to March 2021). Considerable knowledge gaps were observed regarding anatomy, physiology, and vocal disorders management. The vast majority of participants (94.1%) had at some point
experienced problems with their voice. Gastroesophageal reflux (21.6%), vocal nodules (12.5%), and vocal polyps (3.9%) were the most frequently mentioned diagnoses in our sample. A small proportion of participants (9.5%) stated that they have never visited an ENT, while 84.3% have never seen
a speech and language therapist. The total scores on the SVHI in our sample were compatible to the ones in previous studies targeting healthy professional and amateur artists (range 0–116, mean 32, SD 24.7). CONCLUSIONS: This study provides insights into Greek performing artists’
knowledge and attitudes regarding vocal health and may pave the way towards improving vocal health awareness among performing artists.

Objective: To describe the annual medical direct costs per hemophilia A (HA) patient in the Brazilian public healthcare system (SUS) and to understand and describe the patients’ hospital journey, demographical characteristics, and the procedures in the. Methods: This retrospective analysis of DataSUS databases. Data from individuals with registries of HA treatment were gathered between January 1st, 2018, and June 30th, 2021. Besides the D66 ICD-10th code (HA), were also considered the occurrence of some procedures like factor VIII dosage and by-pass therapy dispensation or administration as inclusion criteria. Exclusion criteria were occurrence of factor IX dispensation and female patients were excluded, among others. A record linkage using sociodemographic characteristics was conducted to identify unique patients. Results: Were identified 2,298 individuals underwent ambulatory and 1,018 underwent hospital treatments. The results show that most patients are from the Southeast region of the country, white and middle-aged individuals. The median cost of HA treatment per patient-year was BRL 90.36 for ambulatory care and BRL 1,015.31 for hospital care procedures. The costs were significantly higher for more severe patients and for those between 12 and 18 years old (BRL 1,974.75 and BRL 1,049.09, respectively). Conclusion: The evidence demonstrated encourages the implementation of policies aiming to improve the quality of care provided to patients with HA. Providing referral centers for hemophiliac patients is primordial for the success of the treatment and can result in efficiency.

Published: March 2023

After Zadeh introduced the concept of z-number scientists in various fields have shown keen interest in applying this concept in various applications. In applications of z-numbers, to compare two z-numbers, a ranking procedure is essential.  While a few ranking functions have been already proposed in the literature there is a need to evolve some more good ranking functions.  In this paper, a novel ranking function for z-numbers is proposed- "the Momentum Ranking Function"(MRF). Also, game theoretic problems where the payoff matrix elements are z-numbers are considered and the application of the momentum ranking function in such problems is demonstrated.

First a rectangular microstrip patch antenna is designed which operates at 9.97 GHz. Microstrip patch antenna has several disadvantages like low gain, low bandwidth and low directivity. A metamaterial inspired superstrate layer above the microstrip patch antenna is inserted to increase these parameters. The metamaterial inspired superstrate layer consists of array (5x5) of two rectangular split ring resonators on the top of that layer. The split rings resonator works a metamaterial which improves the performances of conventional antenna. The superstrate acts as a lens which convergences all the electromagnetic radiation coming from the patch and increases the radiations. The metamaterial properties are verified. This antenna is design in HFSS.
Pilot Allocation Technique for Massive MIMO Systems Based on Clustering
Authors: Dey Abhinaba , Pattanayak Prabina
Published: March 2023

Pilot contamination has been identified as one of the major bottlenecks for the functioning of massive multiple-input-multiple-output (MIMO) cellular network. It is caused by the reuse of similar pilot signals by various users present in the cellular network required for channel estimation. In this paper, a cluster-based pilot reuse technique has been proposed where users present in different cluster reuse the same pilot signal. The technique is inspired from co-channel frequency reuse and allocates similar pilots to users which are at a considerable distance from each other. The simulation results presented substantiate the profficiency of the technique in eliminating the resisting effects of pilot contamination on system sum-rate in inter-cluster network.
An Efficient PAPR Reduction Scheme for Delta Sigma Modulated Hybrid NOMA System
Authors: Mathur Harshita , Deepa T.
Published: March 2023

System based on orthogonal frequency division multiplexing with non-orthogonal multiple access represents one of the most promising technology for the next generation of broadcasting and communication systems. One of the main challenges in OFDM-based systems is achieving a high peak-to-average power ratio (PAPR). This paper proposes a novel precoding method, namely Zadoff-Chu matrix transform, for PAPR reduction in OFDM NOMA systems. On top of that, continuous-magnitude OFDM signals require an expensive mixed-signal DAC, and LED drivers need to be modified. Using delta-sigma modulators (DSM), we propose that continuous magnitude OFDM symbols can be converted into signals of LED driver using visible light OFDM systems by introducing ZCT precoded DSM based OFDM NOMA system in this work. This can reduce nonlinear distortion in the DAC and driving circuits due to a high PAPR. We demonstrate that the developed scheme successfully reduces PAPR in a remarkably better way.

Published: March 2023

Pleuroparenchymal fibroelastosis is a recently recognized clinical entity characterized by interstitial pneumonia that has pathological characteristics with proliferating elastin in the upper lung regions. Pleuroparenchymal fibroelastosis is categorized as idiopathic or nonidiopathicdepending on coexistent initiating factors; however, congenital contractural arachnodactyly, which is caused by abnormal production of elastin based on a mutation in the fibrillin-2 gene, rarely reports lung lesion especially features resembling pleuroparenchymal fibroelastosis. We present a case of nonidiopathicpleuroparenchymal fibroelastosis in a patient with a novel mutation in the fibrillin-2 gene, which encodes the prenatal fibrillin-2 protein as a scaffold for elastin.
Distinct effects of Fgf7 and Fgf10 on the terminal differentiation of murine bladder urothelium revealed using an organoid culture system
Authors: Suda Kazuto , Matsumoto Yuka , Ochi Takanori , Koga Hiroyuki , Hattori Nobutaka , Yamataka Atsuyuki , Nakamura Tetsuya
Published: March 2023

Background
Dysregulation of the terminal differentiation of bladder urothelium is associated with the pathogenesis of urinary tract disorders. Fibroblast growth factor (Fgf)7 and Fgf10 stimulate urothelial proliferation; however, their roles in cellular differentiation remain unclear. In this study, we used an organoid system to investigate the roles of these Fgfs in regulating bladder urothelium differentiation and identify their distribution patterns in the mouse bladder.
Methods
Adult bladder epithelia (AdBE) isolated from adult mouse bladder tissues (AdBTs) were used to culture adult bladder organoids (AdBOs) in the presence of Fgf7 and Fgf10. The differentiation status of the cells in AdBTs, AdBEs, AdBOs, and neonatal bladder tissues (NeoBTs) was analyzed via quantitative real-time-PCR for the presence of undifferentiated cell markers (Krt5, Trp63, and Krt14) and differentiated cell markers (Krt20, Upk1a, Upk2, and Upk3a). Organoid cell proliferation was assessed by counting cell numbers using the trypan blue method. The effects of Fgf7 and Fgf10 on organoid differentiation were assessed using different doses of Fgfs, and the involvement of peroxisome proliferator-activated receptor γ (PPARγ) signaling in these processes was tested by introducing a PPARγ agonist (Rosiglitazone) and antagonist (T0070907) to the culture. The expression patterns of Fgf7 and Fgf10 were examinedvia in situ hybridization of AdBTs.
Results
AdBOs showed higher expression of undifferentiated cell markers and lower expression of differentiated cell markers than AdBTs, NeoBTs, and AdBEs, indicating the relatively immature state of AdBOs. Differentiation of AdBOs was enhanced by Rosiglitazone and Fgf7, suggesting an interplay of intracellular signals between Fgf7 and PPARγ. Co-addition of T0070907 suppressed Fgf7-mediated differentiation, demonstrating that PPARγ is activated downstream of Fgf7 to promote cellular differentiation into umbrella cells. Furthermore, we found that Fgf7 is predominantly expressed in the umbrella cells of the urothelium, whereas Fgf10 is predominantly expressed in the urothelium and stroma of AdBTs.
Conclusions
We demonstrated that unlike Fgf10, Fgf7 induces cellular differentiation via PPARγ activity and has a unique tissue distribution pattern in the adult bladder. Further studies on the Fgf7-PPARγsignaling axis would provide insights into the differentiation mechanisms toward functional umbrella cells and the pathogenesis of several urinary tract diseases.

Published: March 2023

Background

The optimal nutritional treatment for gestational diabetes (GDM) is still a matter of debate. With increasing rates of GDM and potential negative consequences for the health of mother and child, the best treatment should be established. The Nordic diet with emphasis on plant-based protein shows promising health outcomes in other populations but has yet to be investigated in GDM population. The aim of the eMOM pilot study was to compare the short-term effects of healthy Nordic diet (HND) and the currently recommended moderate restriction of carbohydrates diet (MCRD) on glucose and lipid metabolism in women with GDM.

Methods

This was a 14-day randomized crossover diet intervention. In total, 42 pregnant women diagnosed with GDM (< 29 + 0 gestational week) were randomized. The run-in to the crossover was three days of the participants’ regular diet, followed by the first allocated three-day intervention diet. This was followed by the second three-day intervention diet. The intervention diets were separated by a three-day wash-out period consisting of the participants’ regular diet. All participants wore a continuous glucose monitor (CGM, Freestyle Libre®, Abbott, USA) for 14 days, and gave blood samples four times during the crossover. The primary outcome was time spent in glucose target range (TIR, < 7.8 mmol/L). TIR, 3-day mean tissue glucose as well as changes in fasting glucose, homeostatic model of insulin resistance (HOMA-IR) and blood lipids were analyzed with paired samples statistical analyses.

Results

36 women with complete 14 days CGM data were analyzed. Both diet interventions produced a high degree of TIR (98% SD 1.8), without a difference between the diets (p = 0.727). The 3-day mean glucose was significantly lower in HND than in MCRD (p = 0.049). Fasting insulin (p = 0.034), insulin resistance (p = 0.03), total and LDL cholesterol (p = 0.023 and 0.008) reduced more in the MCRD diet than the HND. NS differences in any other measure of CGM or blood tests.

Conclusions

HND and MCRD did not differ in terms of their short-term effect on TIR. A larger study with sufficient power is needed to confirm the differences in short-term mean glucose, insulin resistance and lipid metabolism.

Extensive consumption, toxicity, and bioaccumulation of malathion (MLT) and lindane (γ-HCH) pesticides collectively attract the world’s attention. Herein, the nanocomposite of chitosan wrapped NiO@ZnO was synthesized by a green methodology using Azadirachta indica leaves extract. Structural and morphological analysis of chitosan-NiO@ZnO showed hollow sphere-flake shaped image adsorbed on a solid chitosan surface with a large surface area of 73 m2g-1. A decrease in values of lattice strain, dislocation density and crystallite size described the imperfection in crystal geometry and new peaks in FT-IR spectra at 698 cm-1 and 448 cm-1 of Ni-N and Zn-N, respectively confirms the coupling. The chitosan- NiO@ZnO nanocomposite with a reduced band gap due to the generation of new energy levels in the vicinity of of conduction and valence band. Chitosan-NiO@ZnO and individuals nanoparticles (NiO and ZnO) were well-characterized and utilized for degradation MLT and γ- HCH under direct sunlight and dark conditions. The highest degradation of pesticides (above 94%) resulted with 2 mg L-1 and 10 mg L-1 of MLT (π_π) and γ- HCH, respectively with a 20 mg catalyst dose, and pH of ~7 under daylight exposure (5 h). Chitosan-NiO@ZnO substantially suppressed the half-life of the targeted pesticides (MLT: 0.48 h; HCH 0.51 h) and demonstrated the first- order kinetics with a high adsorption capacity, Xm (MLT: 14.5 mg g-1 and γ- HCH 20.7 mg g-1), which also confirmed the strong binding with the pesticides, followed by their conversion into safer and smaller metabolites. The charge separation mechanism was elucidated by UV reflectance and photoluminescence data. Hydroxyl radicals were most frequently responsible for the degradation of pesticides as confirmed by scavenger analysis. The synthesized green-nano photocatalyst showed high reusability (up to 10th cycles), sensitivity, and stability within the degradation process, presumably making it suitable for industrial applications.

Fatigue is a complex physiological phenomenon that reflects worsening physical function and can lead to poor work performance, safety and health conditions. The research targets to obtain the degree of eye fatigue of college students in fixed sitting posture. An eye movement detection method was proposed in this paper. Using the wireless transmission eye tracker and its supporting software from the American Laboratory of Applied Sciences (ASL), three basic types of eye movements were examined, including blink, gaze, and saccade. The results show that with the increase of fatigue, participants’ blink time increased first and then decreased. During fatigue, the pupil diameter increased by about 91% and the percentage of fixation time decreased by about 31.31%. Compared with waking state, the average fixation time increased by about 9%, saccade distance decreased by about 40%. The research results can provide reference for fatigue monitoring and accident prevention.

The implementation of green credits has become an important engine for China's high-quality energy development (HQED). On the basis of constructing an index of HQED and the panel data of thirty provinces in China from 2008 to 2019, this study empirically investigated the effects of green credits on HQED and the action mechanisms behind it in a multi-dimensional manner using a panel fixed-effects model, mediating-effects model, and spatial Durbin model. The results indicated that green credits had significantly contributed to China's HQED, and that conclusion still held true after a series of robustness tests were conducted. It was found that industrial structures and human capital were important channels through which green credits influenced China’s HQED. Moreover, the spatial spillover effects of green credits on HQED were also confirmed. Finally, in terms of temporal heterogeneity, the positive effects of green credits on HQED were found to have increased significantly after 2012. Also, in terms of regional heterogeneity, this study observed that the positive influence of green credits on HQED was more significantly in central and western China than in eastern China, and in southern China than in northern China. The results obtained in this research investigation will potentially provide some important insights for energy planners and policymakers to further the understanding of the drivers of HQED, and the corresponding transmission mechanisms and regional differences.

Bovine mastitis is one of the most economically important diseases in cattle. Infectious mastitis has a viral or bacterial origin. The most common bacterial agents are Staphylococcus, Streptococcus, coliforms, and Bacillus species. These are opportunistic microorganisms that can switch to a pathogenic form, using various virulence factors with follow various pathologies, both animal and human. Three stable microbial consortia, each composed of Bacillus paranthracis and Staphylococcus haemolyticus strains, were isolated from milk of cows diagnosed with mastitis in three geographically remote regions of Russia. The composition of these consortia remained stable following multiple passages on culture media. Apparently, this stability is due to the structure of the microbial biofilms formed by the communities. The virulence of the consortia depended on the B. paranthracis strains. It seems plausible that the ability of the consortia to cause mastitis in cattle was affected by mutations of the cytK gene of B. paranthracis.

Background
We investigated the toxicity and biocompatibility of a novel Mg-3Nd-1Gd-0.3Sr-0.2Zn-0.4Zr (abbreviated to Mg-Nd-Gd-Sr) alloy in the osteoblastic cell line MC3T3-E1 as osteoblasts play an important role in bone repair and remodeling. Methods: We used cytotoxicity tests and evaluation of cell damage and apoptosis to investigate the effects of the Mg-Nd-Gd-Sr alloy on osteoblastic cells. Cell bioactivity, cell adhesion, cell proliferation, mineralization, ALP activity, and expression of BMP-2 and OPG by osteoblastic cells were also used to investigate the biocompatibility of Mg-Nd-Gd-Sr alloy.
Results
The results showed that the Mg-Nd-Gd-Sr alloy had no obvious cytotoxicity, and did not induce apoptosis or cause damage to MC3T3-E1 cells. Compared with the control group, the number of adherent cells within 12 hours was increased significantly in each experimental group (P < 0.05); the OD value of MC3T3-E1 cells was increased significantly in each experimental group on days 1 and 3 of culture (P < 0.05); the number of mineralized nodules formed in each experimental group was significantly increased (P < 0.05), and ALP activity was significantly increased in each experimental group (P < 0.05). RT-PCR results showed that the mRNA expression of BMP-2 and OPG was significantly higher in each experimental group compared with the control group (P < 0.05). Western blotting showed that the Mg-Nd-Gd-Sr alloy extract significantly increased the protein expression of BMP-2 and OPG compared with the control group (P < 0.05).
Conclusions
Our data indicated that the novel Mg-Nd-Gd-Sr-Zn-Zr alloy had no obvious cytotoxic effects, and did not cause apoptosis or damage to MC3T3-E1 cells; meanwhile it promoted cell adhesion, cell proliferation, mineralization, and ALP activity of osteoblasts. During this process, there was an increase in the expressions of BMP-2 and OPG mRNAs and proteins.

There are no data comparing the real-world, long-term clinical outcomes of drug-eluting balloon (DEB) angioplasty and drug-eluting stent (DES) implantation in DES-in-stent restenosis (ISR) lesions. We aimed to compare the real-world, long-term data between DEB and DES in DES-ISR lesions. We analyzed consecutive DES-ISR lesions (225 lesions from 205 patients; male: 66.3%; mean age: 62.4 years) treated with DEB or DES. The primary endpoint was target lesion revascularization (TLR) and the primary safety endpoint was the lesion-oriented composite outcome (LOCO). LOCO is composed of cardiac death, myocardial infarction, or target lesion thrombosis during follow-up. During the 7-year follow-up period, TLR did not differ significantly between DEB (n=108) and DES (n=117) (hazard ratio, 1.07; 95% CI 0.59–1.93, P=0.83). LOCO was significantly lower in the DEB group than in the DES group (hazard ratio, 0.40; 95% CI 0.16–0.98, P=0.04), which was mainly driven by less myocardial infarction (HR 0.24, 95% CI, 0.06–0.94, P=0.04) and absence of target lesion thrombosis in the DEB group (vs. DES group 6%, P=0.02). Additionally, cardiac death was similar between DEB and DES groups (HR 0.56, 95% CI 0.18–1.75, P=0.32).DEB angioplasty showed favorable safety with similar efficacy to that of DES implantation in DES-ISR lesionsduring the long-term follow-up period.
