Background: Vitamin D deficiency is frequently correlated with elevated malondialdehyde (MDA) levels and decreased superoxide dismutase (SOD) activity. Several studies have demonstrated that vitamin D3 can reverse intracellular oxidative stress. However, vitamin D is prone to deterioration and instability. Liprotides contain lipids and proteins that can prevent vitamin D from oxidating.Objective: This study aims to investigate the effects of liprotide-encapsulated vitamin D3 on MDA concentrations and SOD activity in calcium and vitamin D-deficient rat models.Methods: The experimental post-test-only control group study used 24 Wistar rats randomly in 4 groups. Groups K(-), K(+), and P were fed a vitamin D and calcium-depleted AIN-93M diet for 14 days. Standard feed AIN-93M was received by normal groups (KN). Groups K- were deficient rats in vitamin D and calcium without intervention. The groups of K+ and P were given vitamin D3 (180 IU) which was non-encapsulated and liprotide-encapsulated for 28 days.The SOD activity was quantified with Superoxide Dismutase (SOD) Activity Assay Kit, while MDA levels were determined using Thiobarbituric Acid Reactive Substance (TBARS) method. The statistical analysis used One-way ANOVA test with Least Significant Difference follow-up test.Results: The MDA levels and SOD activity in the K+ and P groups had significant differences (p<0.05) against the control group. Liprotides-encapsulated vitamin D3 significantly reduced MDA levels and enhanced SOD activity compared to non-encapsulated in rats with a deficiency in vitamin D and calcium.Conclusion: Liprotide-encapsulated vitamin D3 has the potential to increase SOD activity and decrease MDA levels.

Published: May 2023

Abstract
The present study focuses on the evaluation of a novel prolonged action fertilizer that has been encapsulated by a combination of carboxymethyl cellulose (CMC) and humic acid (HA). The aim of this research was to investigate the release of the essential plant nutrients: phosphorus, nitrogen, and potassium. This study investigated the material composition and nutrient release properties of a novel prolonged action fertilizer encapsulated by CMC and HA. The release of these nutrients was determined by quantifying their concentrations over time using various analytical techniques, such as photometric, titrimetric, and flame photometric methods. The results revealed that the CMC/HA matrix effectively controlled the nutrient release, with extended-release durations observed under acidic (pH 5.0) and neutral (pH 7.0) conditions compared to alkaline environments (pH 8.5). This indicates that the encapsulated fertilizer is well suited for a variety of soil pH conditions, particularly in acidic and neutral soils. This information could have important implications for the development of more sustainable and environmentally friendly fertilizer technologies.

Published: May 2023

Abstract
The present work aims to fabricate new inexpensive epoxy-based composites with a concentration described by the formula (90 − x)epoxy + 10Sb2O3 + xPbO, where x = 5, 10, 15, and 20 wt%. The impacts of the substitution of epoxy by PbO on the composite density and radiation shielding properties of the fabricated composites were studied. The density of the fabricated composites varied between 1.30 and 1.49 g·cm−3, enriching the PbO concentration. Utilizing the narrow beam transmission method, the linear attenuation coefficient (LAC) of the fabricated composites was measured using the NaI (Tl) detector as well as radioactive sources Am-241 and Cs-137. The LAC increased by 84% and 18% at gamma-ray energy of 0.059 and 0.662 MeV, when the PbO concentration raised between 5 and 20 wt%, respectively. Then the transmission rate and half-value layer of the fabricated composites were reduced by raising the PbO concentration. Therefore, the fabricated composite has good shielding properties in the low gamma-ray energy interval to be suitable for medical applications and low radioactive waste container constructions.

Authors: Aydi Rabeb , Ferjani Imen , Krichen Bilel 
Published: May 2023

Abstract
In this paper, we develop some generalized Fredholm perturbation results for bounded linear operators acting on non-reflexive Banach spaces satisfying certain conditions. Furthermore, we investigate the stability of the generalized Schechter S-essential spectrum by means of the so-called generalized Fredholm index. This concept is introduced as a semigroup homomorphism satisfying certain properties. Some generalized Fredholm results for block operator matrices acting on a non-reflexive product of two Banach spaces are also developed.
Reactive compatibilization of polypropylene grafted with maleic anhydride and styrene, prepared by a mechanochemical method, for a blend system of biodegradable poly(propylene carbonate)/polypropylene spunbond nonwoven slice
Authors: Tian Zheng , Zhang Yilu , Xu Nai , Pan Lisha , Feng Yuhong 
Published: May 2023

Abstract
Poly(propylene carbonate) (PPC)/polypropylene (PP) spunbond nonwoven slice has gained more attention, owing to its excellent properties, such as biodegradability, flexibility, biocompatibility, and CO2 utilization. However, the applications of this green material are limited due to the poor thermodynamic incompatibility between PPC and PP. In this paper, PP grafted with maleic anhydride (MAH) and styrene (St) (PP-g-(MAH-co-St)), prepared by a mechanochemical method and having a grafting percentage G
MAH = 1.40 %, was used as a compatibilizer to prepare a biodegradable PPC/compatibilizer/PP composite-spunbond nonwoven slice by melt-blending. The effects of compatibilizer content on the tensile strength, elongation at break, melt flow rate, thermal properties, and micro-morphology of PPC/PP-g-(MAH-co-St)/PP were systematically studied. Furthermore, the mechanism of compatibilization of PP-g-(MAH-co-St) in the PPC/PP spunbond nonwoven composite slice is discussed. The results indicated that this green PP-g-(MAH-co-St) exhibited a clear reactive compatibilization effect. Therefore, it can be considered as a good compatibilizer for the biodegradable PPC/PP spunbond nonwoven slice.

The Use of Social Media by Emergency Stakeholder Groups: Lessons Learned from Areas Affected by Hurricanes Isaac and Sandy
Authors: Kirby Ryan H. , Reams Margaret , Lam Nina S.-N. 
Published: May 2023

Abstract
We present findings from our 2018 survey of organizations involved in emergency management in areas affected by Hurricanes Sandy and Isaac to gain insight into their social media use throughout the four phases of emergencies – preparedness, response, recovery, and mitigation planning. While 90% of the 269 respondents report using social media in their communications with the public, government offices are more active throughout the four phases compared to the other groups. First responders use social media most during the response and preparedness phases, while news media and NGOs are more active during the recovery phase. This suggests that groups that perform emergency-response functions and NGOs play complementary roles in emergency communications. Further, respondents representing government offices and first responders use social media primarily to disseminate information, while news media groups and NGOs expressed more confidence in social media as a mechanism for bi-directional communications. While Facebook is most commonly used to respond to the public, the NGOs and news media groups also use newer, image-based options like Instagram. All groups reported less social media use during the quiet time (mitigation planning phase) between emergencies, suggesting opportunities for these organizations to increase communications with the public before emergencies arise.
Fast multilevel iteration methods for solving nonlinear ill-posed problems
Authors: Yang Suhua , Luo Xingjun , Zhang Rong 
Published: May 2023

Abstract
We propose a multilevel iteration method for the numerical solution of nonlinear ill-posed problems in the Hilbert space by using the Tikhonov regularization method. This leads to fast solutions
of the discrete regularization methods for the nonlinear ill-posed equations.
An adaptive choice of an a posteriori rule is suggested to choose the stopping index of iteration,
and the rates of convergence are also derived. Numerical results are presented
to demonstrate the efficiency and accuracy of the proposed method.

Published: May 2023

Abstract
We demonstrate heterogeneous integration of active semiconductor materials into the conventional passive metal-insulator-metal (MIM) waveguides to provide compact on-chip light generation and detection capabilities for chip-scale active nanophotonic platforms. Depending on its bias conditions, a metal-semiconductor-metal section can function as either a light emitting diode or a photodetector directly connected to the MIM waveguides. We experimentally verify the independent and combined operations of electrically-driven on-chip light sources and photodetectors.
Dynamic selection of visible wavelengths using resonant TiO2 nanostructures

Published: May 2023

Abstract
All-dielectric nanoarrays have strong electromagnetic resonances with various interesting applications and are tuned by adjusting their geometrical parameters. However, their optical properties are permanently encoded during fabrication. This study presents robust dynamically tunable all-dielectric nanoresonators for controllable, reversible, and reproducible color filtering. Our design uses an array of TiO2 nanodiscs embedded in a transparent, stretchable polydimethylsiloxane (PDMS) membrane and exhibits a narrow spectral response due to Mie magnetic and electric dipole resonances hybridized with the TiO2 nanodiscs lattice modes. By mechanically stretching the PDMS membrane, the pitch of the TiO2 nanodiscs was increased and the spectral location of the resonances was altered. Additionally, an optically asymmetric structure was fabricated by partially embedding TiO2 nanodiscs in PDMS. Thus, the magnitude of the Rayleigh anomaly diffraction, which could interrupt the dipole resonances, was reduced. Our design has sharp, frequency-tunable resonances in the visible spectrum, and we demonstrated dynamic tunability by stretching the metasurfaces.

A TANULMÁNY CÉLJA
Világszerte számos kutatást végeztek az m-health applikációkkal kapcsolatban, és az eredmények azt mutatják, hogy a jól megtervezett m-health alkalmazások javíthatják a gyógyszeres kezelést, és csökkenthetik az egészségügyi ellátás költségeit. Kutatásunk célja, hogy feltárjuk az m-health applikációk és különös tekintettel az életstílus-alkalmazások használatának elméleti hátterét és tapasztalatait felhasználói szemszögből.
ALKALMAZOTT MÓDSZERTAN
Az m-health alkalmazások használatát vizsgáló kérdőívek (MAUQ) közül az önálló applikációkra kifejlesztett skálát használtuk. Az applikációk értékelése három dimenzió mentén történt: a használat könnyűsége, az applikáció felületével való elégedettség, és a hasznosság megítélése. A két kutatási kérdés vizsgálatához kísérleti módszert alkalmaztunk, amit 22 hallgató bevonásával bonyolítottunk le, a 2021-es tanév őszi félévében, 14 héten keresztül. Az elemzés során leíró statisztikai mutatókat és páros t próbát alkalmaztunk.
LEGFONTOSABB EREDMÉNYEK
A vizsgált alanyok összességében 16 különböző applikációt értékeltek, melyek az életstílus applikációk öt területéhez sorolhatók: (1) sport és fitnesz tevékenységmérő, (2) étrend és táplálkozás, (3) stresszoldás és relaxáció, (4) női ciklus figyelés, illetve (5) betegségkezelés. A kísérletben résztvevő alanyok leginkább a könnyű használattal elégedettek és legkevésbé az applikációk felületével, valamint annak hasznosságának megítélésével. A kísérleti alanyok közül többen számoltak be pozitív hatásokról a fizikai és a mentális egészség javulása által. Az észlelt egészségjavulás szignifikáns (t=-4,55; p≦0,00) és a legkedvezőbb változás a diéta és táplálkozási alkalmazások esetében figyelhető meg. Biztató, hogy 17-en tervezik az applikációk további használatát.
GYAKORLATI JAVASLATOK
Kutatásunk eredményei különösen hasznosak lesznek az egészségtudatosságra és egészségfejlesztésre fókuszáló fogyasztók, alkalmazásfejlesztők és szolgáltatók számára. Az egészségügy esetében hozzájárulhat az ellátórendszer terheinek csökkentéséhez, valamint a telemedicina és a hagyományos egészségügy integrált fejlesztéséhez. Népességi szinten kiemelt szerepe van a megelőzés területén. A fejlesztőknek érdemes lenne nagyobb figyelmet szentelni az appok felületének fejlesztésére, a design-ra, a rendszerezésre, vagyis ergonómiai szempontokra. Ezen kívül, a fejlesztők számára lehetőséget kínál az ingyenesen elérhető szolgáltatások bővítésére, valamint a BigData adatok GDPR előírásainak megfelelő kezelésére, elemzésére.

Mechanism of 5S RNP recruitment and helicase‐surveilled rRNA maturation during pre‐60S biogenesis
Authors: Lau Benjamin , Huang Zixuan , Kellner Nikola , Niu Shuangshuang , Berninghausen Otto , Beckmann Roland , Hurt Ed , Cheng Jingdong 
Published: May 2023

AbstractRibosome biogenesis proceeds along a multifaceted pathway from the nucleolus to the cytoplasm that is extensively coupled to several quality control mechanisms. However, the mode by which 5S ribosomal RNA is incorporated into the developing pre‐60S ribosome, which in humans links ribosome biogenesis to cell proliferation by surveillance by factors such as p53–MDM2, is poorly understood. Here, we report nine nucleolar pre‐60S cryo‐EM structures from Chaetomium thermophilum, one of which clarifies the mechanism of 5S RNP incorporation into the early pre‐60S. Successive assembly states then represent how helicases Dbp10 and Spb4, and the Pumilio domain factor Puf6 act in series to surveil the gradual folding of the nearby 25S rRNA domain IV. Finally, the methyltransferase Spb1 methylates a universally conserved guanine nucleotide in the A‐loop of the peptidyl transferase center, thereby licensing further maturation. Our findings provide insight into the hierarchical action of helicases in safeguarding rRNA tertiary structure folding and coupling to surveillance mechanisms that culminate in local RNA modification.

Background. Surgery is fundamental in complex and combined approach in the treatment of the early breast cancer. It is a common fact, that absence of tumor cells in the resection margin is the main indicator of oncological safety of the breast-conserving surgery (BCS). The presence of tumor cells in examined margin is the predictor of local recurrence after BCS for breast cancer. Currently the clinical need for precise and fast method of intraoperative assessment of the resection margin status is kept. Intraoperative evaluation of the resection margin with the usage of digital two-point sectorography (Faxitron PathVision) appeared as the alternative to intraoperative histological examination, providing the optimum size of the information about adequacy of the carried out surgical treatment.Aim. To evaluate diagnostic features of the digital two-point sectorography Faxitron PathVision in the intraoperative assessment of the resection margin status after the surgical treatment in comparison with planned histologic examination.Materials and methods. 368 conducted conservative surgeries were analyzed; patients were divided in two groups depending on neoadjuvant chemotherapy. The first group of patients included 236 patients, who didn't receive neoadjuvant chemotherapy before surgery; second group included 132 patients, who received neoadjuvant chemotherapy. Subset analysis of detection rate of the positive resection margin (R1) was carried out with the usage of the intraoperative assessment of the resection margin on the X-ray device Faxitron PathVision or without this method. After each BCS resection margin status was assessed on planned histologic examination for the presence of the tumor cells, with subsequent analysis of the frequency of reoperations when R1 was found.Results. In 368 tested surgical specimens after BCS R1 was found in 25 cases, which is 6.8 %. From 236 patients in the first group after BCS R1 was found in 20 cases, which is 8.5 %; from 132 conducted operations in the second group in 5 (3.8 %) cases the presence of R1 is found. Reoperations were performed in 13 cases and tumor cells were found in 3 cases in the sub-group which didn't receive intraoperative assessment with X-ray device Faxitron PathVision.Conclusions. Assessing the results of our study we can make a conclusion about the positive experience of performing BCS and intraoperative evaluation of the resection margin with the usage of the digital two-point sectorography (Faxitron PathVision) and low frequency of R1 (3.8 %) in comparison with absence of this method (8.5 %).

Published: May 2023

Background. One-stage prepectoral implant-based reconstruction (OSPIBR) using biocompatible synthetic meshes support gained wide popularity in breast cancer surgery. Optimal structure of polypropylene mesh implants (PMI) and methods of its application are actively discussed.Aim. To study the effectiveness and safety of prosthesis support with “heavy” PMI in OSPIBR. Materials and methods. During 2019-2021 18 OSPIBR with "heavy" PMI support were performed after subcutaneous mastectomies in 14 patients. Cancer was indication for surgery in 13 cases (two of them - with BRCA1 mutation) and BRCA1 mutation solely - in 1 case. Foamed polyurethane covered silicone prosthesis (Polytech, Germany) was used for OSPIBR and "heavy" PMI PROLENE™ Polypropylene Mesh (Ethicon/Johnson & Johnson, USA) for prosthesis support by original method.Results. The overall complication rate was 5.6 % (1/18). It was a minor complication: limited aseptic skin necrosis along incision edge, successfully excised under local anesthesia. No cancer recurrences or capsular contracture formation were registrated during follow-up (6 months). The cosmetic outcome (Harvard score) was excellent in 11 of them and good in 3.Conclusions. "Heavy" PMI application by original technique in OSPIBR after subcutaneous mastectomy for breast cancer is a safe and effective method of prosthesis support.
