Psoriasis is caused by chronic inflammation of the skin that occurs in various countries. Current therapy is still dominated by long-term anti-inflammatory which causes various side effects. Hypoxic secretome mesenchymal stem cells (SHMSCs) contain soluble molecule bioactive anti-inflammatory cytokines that can suppress inflammation. However, the role of SHMSCs on IL-6 gene expression in psoriasis-like has not been studied until now. The aim of this study was to determine the effect of SH-MSC administration on IL-6 gene expression in Psoriasis-like rats induced by IMQ 100 mg. The research design is an experimental posttest control group design. The experimental subject was divided into four treatment groups consisting of a healthy group (no treatment), positive control group (only IMQ 100 mg), P1 group (SH-MSC therapy 100 μL/kgBW in 100 mg cream) and P2 group (SH-MSCs therapy 200 µL/kgBW in 100 mg cream). P1 and P2 were given SH-MSC topically for 14 days. At the end of the treatment, termination, extraction skin and IL-6 gene expression analysis by qRT-PCR.

Abstrak

Memperoleh pendampingan hukum merupakan salah satu hak yang dimiliki oleh seorang terdakwa ketika menjalani proses peradilan. Pemberian bantuan hukum kepada terdakwa selama masa pandemi Covid-19 sedikit banyak mengalami kendala. Beralihnya mekanisme pendampingan hukum selama masa Pandemi Covid-19 yang dahulu dilaksanakan tatap muka secara langsung menjadi daring menggunakan perantara alat elektronik dianggap memicu munculnya hambatan dan kendala bagi Posbakum untuk melakukan pendampingan hukum secara optimal kepada terdakwa. Berdasarkan hal tersebut, Penelitian ini dilakukan untuk mencari tahu sejauh mana peran Posbakum sebagai penyedia layanan hukum cuma-cuma di pengadilan dan efektivitas pelaksanaan pemberian bantuan hukum yang dilakukan oleh Posbakum kepada terdakwa selama masa Pandemi Covid-19. Penelitian dilakukan menggunakan metode yuridis empiris, sehingga permasalahan tidak hanya dilihat secara normatif, tetapi juga melihat bagaimana kenyataan yang terjadi di lapangan secara langsung. Data lapangan didapatkan melalui hasil observasi dan wawancara dengan beberapa narasumber yang memiliki keterlibatan dengan proses pemberian bantuan hukum. Hasil penelitian menunjukkan bahwa pelaksanaan pemberian bantuan hukum yang dilakukan oleh Posbakum Pengadilan Cibinong selama masa Pandemi Covid-19 belum sepenuhnya efektif karena dalam pelaksanaannya masih menemukan kendala-kendala yang menjadikan pendampingan hukum tidak dapat diberikan secara optimal, sebagai akibat dari keterbatasan interaksi dan komunikasi antara penasihat hukum dengan terdakwa dan ketiadaan sarana atau prasarana yang kurang mumpuni.

Published: March 2023

Today’s modern era has made it essential for everyone, even for the privacy of their homes, to have controllable, affordable, and easy-to-use security systems. The creation of a cost-effective, straightforward, and feature-rich home security alarm system using a Raspberry Pi Zero W microprocessor and MQTT protocol is discussed in this paper. The proposed system is primarily intended for outlying areas with limited or insufficient network bandwidths. Together with sensors such a PIR (passive infrared sensor), sound sensor, gas leakage sensor, obstacle/proximity sensor (vibration sensor), fire/flame sensor, GSM module, and a surveillance pi camera, it makes use of a Raspberry Pi Zero W as a microprocessor. [1]. In addition, the system will promptly alert the homeowner through phone calls, SMS, or mail anytime it senses the presence of an intruder or other safety hazards. Hence, anyone who wants to make their space (bank, home, workplace, jewelry shops, and cabins) safe and to protect themselves from theft and infiltration can use this system at a fair price.

Clinical Case: We present a case of systemic amyloidosis AL with unusual cardiac, mesenteric, renal, peritoneal, and gastrointestinal involvement, in which the diagnostic hypothesis was formulated on the basis of problem-solving and ultrasound technique (abdomen, lung, heart ultrasound). Conclusion: This case shows that multi-organ ultrasound, associated with problem-solving, may be very helpful in the diagnosis of systemic diseases, even unusual ones, avoiding a long diagnostic interval length.
A Carta de Jeremias aos exilados (Jr 29,1-14): reconstruir no presente com o olhar no futuro
Authors: Dagostim Minatto Davi
Published: March 2023

Os tempos de reconstrução nem sempre são momentos ideais, favoráveis. Muitas vezes é necessário reconstruir em situações hostis, que pouco inspiram a esperança. O presente artigo procura explorar a difícil situação vivida pelos exilados de Judá quando receberam uma carta do profeta Jeremias exortando-os a reconstruírem suas vidas na Babilônia, longe de sua terra e de seus ideais. Eles foram convidados a plantar, edificar casas, unir-se em matrimônio, gerar filhos, procurar a paz e rezar pela Babilônia, pois sua permanência na terra do exílio não seria breve, ao contrário do que os falsos profetas procuravam apregoar. A “carta aos exilados”, como ficou conhecida, deve ter sido um duro golpe às expectativas humanas dos exilados, mas continha sábias instruções para que os judaítas pudessem reconstruírem suas vidas com os pés na realidade e com os olhos no futuro esperado para seus filhos. Justamente por isso, esta carta pode trazer inspiração também para nós hoje, pois os tempos de reconstrução às vezes são difíceis, mas a sabedoria para lutar e esperar passa pela capacidade de olhar para frente com os pés no chão.
ESTATUTO DA PESSOA COM DEFICIÊNCIA E SUAS IMPLICAÇÕES NO CÓDIGO CIVIL
Authors: Freitas Gisele Meline Fagundes
Published: March 2023

O Estatuto da Pessoa com Deficiência alterou diversos dispositivos do Código Civil, e isso trouxe inúmeras perdas aos portadores de deficiência, que não contam mais com dispositivos legais que lhes asseguravam diversos privilégios pela condição de deficiente. Retirou o deficiente do rol de incapacidades, o que provocou muitos reflexos em outros Institutos do Direito Civil, repercutindo na aplicação dos institutos que afirmam invalidades, prescrição, decadência, quitação, doação, casamento e curatela, e introduzindo um novo instituto assistencial conhecido por Tomada de Decisão Apoiada. A qualidade dessas mudanças interfere diretamente na vida dos portadores de deficiência, e ter uma base de como era a situação do deficiente no ordenamento jurídico antes dessas mudanças é fundamental para entendê-las assim como a sua conveniência nesse momento. As mudanças apesar de serem vistas como positivas ao deficiente pela maior autonomia que agora possuem, restringindo a atuação dos curadores e apoiadores, não podem minimizar as perdas resultantes da retirada dessas pessoas da condição de incapaz.
LEITURA E ESCRITA NO BRASIL-COLÔNIA: RATIO STUDIORUM VERSUS AULAS RÉGIAS
Authors: Costa Júlio Resende , Dos Santos Sônia Maria
Published: March 2023

Circunscrito no campo da história e historiografia da educação brasileira, este artigo buscou reconstruir o sentido e as representações sociais da alfabetização no Brasil-Colônia, com recorte temporal delimitado entre 1549 e 1822. A opção metodológica adotada foi a pesquisa bibliográfica e o estudo possui cunho qualitativo e descritivo. O texto analisa as concepções de alfabetização a partir de duas doutrinas distintas: a primeira, a alfabetização sacra, de concepção metafísica do conhecimento e da natureza humana, forjada no interior do Ratio Studiorum, sob a responsabilidade dos missionários da Companhia de Jesus jesuítas; e a segunda, de concepção laica, influência iluminista e científica, nascida da implantação das Aulas Régias e sob o comando das reformas pombalinas. O paradigma de educação exercido no período colonial prezava a instrução de indivíduos dóceis, obedientes à religião e ao Estado, em prejuízo da formação intelectual. Para os homens brancos, livres e ricos, a formação propedêutica e o ensino erudito. Para os homens pobres, a preparação para o trabalho. Para os indígenas, a doutrina religiosa e a conversão ao catolicismo. Para as mulheres, os trabalhos manuais e a dedicação à casa, ao marido e aos filhos. Aprender a ler e escrever, no período colonial brasileiro, era uma habilidade excludente: o acesso a essa instrução privilegiava os homens brancos e ricos. Ser alfabetizado significava verbalizar textos escritos e reescrevê-los, mecanicamente. A ênfase do processo de alfabetização estava na oratória e na retórica, em detrimento da competência de interpretar e compreender, com competência, o que estava escrito.

Authors: COOC NORTH , YANG MAN
Published: March 2023

Thirty years after the Council for Exceptional Children's first symposium on Asian American youth with disabilities, this study synthesizes research on the key experiences of this population and their families. Results show that most studies focused on the views of Asian American parents, especially their perceptions of and attitudes toward disabilities, experiences in raising a child with a disability, and interactions with service providers and school officials. Although less frequent, studies also examined the perspectives of service providers and students themselves. An important finding is the diversity in experiences among Asian American parents due to religion, acculturation, education, and income level. The review has implications for research, practice, and policy related to serving Asian American children with disabilities.

Engaging with Water and Rivers from a Multispecies Justice Perspective
Authors: Houart Carlota
Published: March 2023

Rivers are ecosystems indispensable for the survival of both humans and non-human species. Yet humans often disregard their importance and modify the existing socio-natural equilibrium of rivers in the pursuit of economic and political agendas. With a focus on new water justice movements, this article advocates a perspective that recognizes rivers as hydrosocial territories, actively and continuously co-created, co-inhabited, and transformed by a multiplicity of human and other-thanhuman beings. Such a perspective opens a path to a multispecies justice framework that involves rethinking the relations between human and non-human beings in the worlds we share as a medium for creating more socio-ecologically just and biodiverse water worlds.
Looking Back Paves our Way Forward: The Delta City of Amsterdam
Authors: Peters Sannah , Ouboter Maarten Reinier Lemme , Oomkens Jeroen
Published: March 2023

As one of the most famous delta cities in the world, Amsterdam exemplifies how decisions and narratives from the past can be the driving force for present-day actions and more effective design principles for future city planning. Water management in Amsterdam has often been, and frequently still is, reactive in response to water hazards, flooding, droughts, pollution and disease. While contemporary pressures urge water managers to redesign the living environment in harmony with changing water cycles, the centuries-long history of water awareness, cumulative knowledge and long-term spatial planning has led to gradual improvement throughout Amsterdam. Many solutions are still relevant today and are essential in decision making as we design a new climate-resilient future and deal with challenges such as sea-level rise and demographic change. Despite residing below sea level, the people of the delta city of Amsterdam exhibit a profound sense of confidence and security against flooding. Moreover, the material and immaterial dimensions of the water network serve as a tangible reminder of our ancestors’ deltaic identity, highlighting their contributions to our current living environment. Therefore, the water system plays a vital role in preserving Amsterdam’s urban landscapes, cultural heritage and historical significance, which also helps strengthen this delta city’s future water management and urban planning.

Published: March 2023

Land use types can of considerable interest in efforts to quantify soil organic C and nitrogen (N) cycling, both of which are important for soil stability and fertility. A study was carried out on a tropical rainforest soils in southern Nigeria to quantify soil organic carbon and nitrogen pools and other indices under forested, 5-year fallow, cocoa plantation and a 5-year continuous cassava land uses. Soil samples were collected at 0-15 cm and 15-30 cm depths for measurement of these indices. Results revealed that total organic carbon (TOC and total nitrogen (TN) varied significantly among the different land uses. TOC of 30.2 g kg-1 was higher (p<0.05) in forested soils at in the 0-15 cm top soil and 22.3 g kg-1 in the subsoil. Total N was statistically significant (p<0.05) at 2.61 and 2.01 in forested and 5-year fallowed soils, respectively. The carbon pool index (CPI) was significant at 1.63 in forested soils, while nitrogen pool index (NPI) 1.30 in similar soil (p<0.05) in 0-15 cm topsoil. In 15-30 cm subsoil, CPI and NPI values were in the order of forested > cocoa plantation > 5-year cassava cultivation, with the least values of 0.44 CPI and 0.35 NPI found in 5-year cassava plots. It was concluded that CPI and NPI are valuable indicators for analyzing changes in soil quality induced by maintaining a 5-year fallow. It was found that forested and 5-year fallow land uses can be used to improved C and N stock, as well as the structural and hydraulic properties of the soils.

Published: March 2023

Carbon aerogels (CAs) are desirable for thermal protection in aerospace because of their lightweight and high‐temperature insulation characteristic; however, their intrinsic brittleness and flaw sensitivity easily trigger catastrophic failure when resisting high‐frequency thermal shocks or complex mechanical stresses. Compression is the predominant load applied on aerogels by aerodynamic pressure and pre‐tightening force; therefore, the structural elasticity and exceptional capability to keep thermal performance under impact stress are crucial in deciding the actual availability of aerogels. This review presents the recent progress in newly resilient CAs for thermal protection, focusing on reliable structural stability, thermal stability, and thermal superinsulation property. The influence law of microstructures on heat transfer behaviors is first investigated, followed by construction strategies for adiabatic CAs, emphasizing the recoverable deformability resulting from increased continuity of building blocks from 0D nanoparticles to 1D nanofibers/nanotubes and then to 2D nanosheets. Moreover, the optimization of thermal stability in high‐temperature aerobic environments and thermal insulation performance are discussed. Finally, it raises current challenges and further opportunities for CAs toward better properties and brighter prospects.

Metal oxides are considered as stable and low‐cost photoelectrode candidates for hydrogen production by photoelectrochemical solar water splitting. However, their power conversion efficiencies usually suffer from poor transport of photogenerated charge carriers, which has been attributed previously to a variety of effects occurring on different time and length scales. In search for common understanding and for a better photo‐conducting metal oxide photoabsorber, CuFeO2, α‐SnWO4, BaSnO3, FeVO4, CuBi2O4, α‐Fe2O3, and BiVO4 are compared. Their kinetics of thermalization, trapping, localization, and recombination are monitored continuously 100 fs–100 µs and mobilities are determined for different probing lengths by combined time‐resolved terahertz and microwave spectroscopy. As common issue, we find small mobilities < 3 cm2V‐1s‐1. Partial carrier localization further slows carrier diffusion beyond localization lengths of 1–6 nm and explains the extraordinarily long conductivity tails, which should not be taken as a sign of long diffusion lengths. For CuFeO2, the localization is attributed to electrostatic barriers that enclose the crystallographic domains. The most promising novel material is BaSnO3, which exhibits the highest mobility after reducing carrier localization by annealing in H2. Such overcoming of carrier localization should be an objective of future efforts to enhance charge transport in metal oxides.

Published: March 2023

When skin trauma occurs, rapid achievement of the post‐wound closure is required to prevent microbial invasion, inhibit scar formation and promote wound healing. To develop a wound dressing for accelerating post‐wound‐closure and wound healing, a thermo‐responsive and tissue‐adhesive hydrogel with interpenetrating polymer networks (IPN) is fabricated based on N‐dimethylbisacrylamide (NIPAM) and glutaraldehyde (GTA) cross‐linked hyaluronic acid (HA). Results not only confirm the thermo‐stimulated self‐contraction and tissue adhesiveness of the HA‐based IPN (PNI‐HA), which effectively aids wound closure via mechanical stretch, but also verify the hemocompatibility and cytocompatibility of PNI‐HA that tend to accelerate wound healing. In vivo, a mouse model of total skin defect demonstrates that PNI‐HA acting as hydrogel sealant significantly achieves the sutureless post‐wound‐closure at the early stage of wound healing, and then promotes wound healing by reducing inflammatory cells infiltration, promoting angiogenesis as well as reducing collagen deposition. These results indicate that the developed thermo‐responsive and tissue‐adhesive hydrogel dressing offers a candidate to serve as a tissue sealant for wound healing.

Lignin is a nontoxic and biocompatible biopolymer with many promising characteristics, including a high tensile strength and antioxidant properties. This natural polymer can be processed through several chemical methods and modified into lignin nanomaterials for potential biomedical applications. This review summarizes the latest developments in nanolignin (NL)‐based biomaterials for cancer therapy; various NL applications related to cancer therapy are considered, including drug and gene delivery, biosensing, bioimaging, and tissue engineering. The manuscript also outlines the potential use of these materials to improve the therapeutic potency of chemotherapeutic drugs by decreasing their dose and reducing their adverse effects. Due to its high surface area‐to‐volume ratio and the easy modification of its chemical components, NL could serve as an appropriate matrix for the binding and controlled release of various pharmaceutical agents. Moreover, the challenges in the utilization of NL‐based materials for cancer therapy are discussed, along with the prospects of advances in such nanomaterials for medical research applications.

Treatment of infected bone defects is a major clinical challenge; bioactive materials combining sufficient antimicrobial activity and favorable osteogenic ability are urgently needed. In this study, through a facile one‐pot hydrothermal reaction of zinc acetate in the presence of tannic acid (TA), with or without silver nitrate (AgNO3), is used to synthesize a TA or TA and silver nanoparticles (Ag NPs) bulk‐modified zinc oxide (ZnO) (ZnO‐TA or ZnO‐TA‐Ag), which is further composited with zein to fabricate porous microparticulate scaffolds for infected bone defect repair. Bulk TA modification significantly improves the release rate of antibacterial metal ions (Zn2+ release rate is >100 times that of ZnO). Fast and long‐lasting (>35 d) Zn2+ and Ag+ release guaranteed sufficient antibacterial capability and excellent osteogenic properties in promoting the osteogenic differentiation of bone marrow mesenchymal stem cells and endogenous citric acid production and mineralization and providing considerable immunomodulatory activity in promoting M2 polarization of macrophages. At the same time, synchronously‐released TA could scavenge endogenous reactive oxygen species (ROS) and ROS produced by antibacterial metal ions, effectively balancing antibacterial activity and osteogenesis to sufficiently control infection while protecting the surrounding tissue from damage, thus effectively promoting infected bone defect repair.

Aiming to solve the trade‐off of “room‐temperature phosphorescence (RTP)–flexibility” in principle, organic RTP crystals with elastic/plastic deformation are realized. These properties are mainly due to the divisional aggregation structures of aromatics and alkoxy chains, and can be modulated by the controllable molecular configurations. The longest RTP lifetime of 972.3 ms is achieved as the highest record for organic flexible crystals. Plastic crystals with persistent RTP are realized, which can be applied into biomedical optical technologies by afterglow delivery. Moreover, the relationship among elastic/plastic deformation, RTP property, and aggregated structures is established. The elastic/plastic deformation is mainly determined by the difference of interaction energies from the aromatics and the alkoxy chains. For the BP‐OR series with twisted configurations, the alkoxy chain with the middle length is favorable for the RTP property, while the strength of the π–π coupling is the cruical factor to the RTP property of the Xan‐OR series with planar skeletons. A new way to promote the development of flexible RTP crystals, by modulation of aggregated structures as well as rational distribution of intermolecular interactions, is explored.

Reactive oxygen species (ROS)‐mediated tumor catalytic therapy is typically hindered by gap junction proteins that form cell‐to‐cell channels to remove cytotoxic ROS, thereby protecting tumor cells from oxidative damage. In this work, a multifunctional nanozyme, FePGOGA, is designed and prepared by Fe(III)‐mediated oxidative polymerization (FeP), followed by glucose oxidase (GOx) and GAP19 peptides co‐loading through electrostatic and π–π interactions. The FePGOGA nanozyme exhibits excellent cascade peroxidase‐ and glutathione‐oxidase‐like activities that efficiently catalyze hydrogen peroxide conversion to hydroxyl radicals and convert reduced glutathione to oxidized glutathione disulfide. The loaded GOx starves the tumors and aggravates tumor oxidative stress through glucose decomposition, while GAP19 peptides block the hemichannels by inducing degradation of Cx43, thus increasing the accumulation of intracellular ROS, and decreasing the transport of intracellular glucose. Furthermore, the ROS reacts with primary amines of heat shock proteins to destroy their structure and function, enabling tumor photothermal therapy at the widely sought‐after mild temperature (mildPTT, ≤45 °C). In vivo experiments demonstrate the significant antitumor effectof FePGOGA on cal27 xenograft tumors under near‐infrared light irradiation. This study demonstrates the successful ablation of gap junction proteins to overcome resistance to ROS‐mediated therapy, providing a regulator to suppress tumor self‐preservation during tumor starvation, catalytic therapy, and mildPTT.

Self‐assembled compartments from nanoscale components are found in all life forms. Their characteristic dimensions are in 50–1000 nm scale, typically assembled from a variety of bioorganic “building blocks”. Among the various functions that these mesoscale compartments carry out, protection of the content from the environment is central. Finding synthetic pathways to similarly complex and functional particles from technologically friendly inorganic nanoparticles (NPs) is needed for a multitude of biomedical, biochemical, and biotechnological processes. Here, it is shown that FeS2 NPs stabilized by l‐cysteine self‐assemble into multicompartment supraparticles (mSPs). The NPs initially produce ≈55 nm concave assemblies that reconfigure into ≈75 nm closed mSPs with ≈340 interconnected compartments with an average size of ≈5 nm. The intercompartmental partitions and mSP surface are formed primarily from FeS2 and Fe2O3 NPs, respectively. The intermediate formation of cup‐like particles enables encapsulation of biological cargo. This capability is demonstrated by loading mSPs with DNA and subsequent transfection of mammalian cells. Also it is found that the temperature stability of the DNA cargo is enhanced compared to the traditional delivery vehicles. These findings demonstrate that biomimetic compartmentalized particles can be used to successfully encapsulate and enhance temperature stability of the nucleic acid cargo for a variety of bioapplications.

Heart rhythm disorders, known as arrhythmias, cause significant morbidity and are one of the leading causes of mortality. Cardiac arrhythmias are frequently treated by implantable devices, such as pacemakers and defibrillators, or by ablation therapy guided by electroanatomical mapping. Both implantable and ablation therapies require sophisticated biointerfaces for electrophysiological measurements of electrograms and delivery of therapeutic stimulation or ablation energy. In this work, a graphene biointerface for in vivo cardiac electrophysiology is reported for the first time. Leveraging sub‐micrometer‐thick tissue‐conformable graphene arrays, sensing and stimulation of the open mammalian heart are demonstrated both in vitro and in vivo. Furthermore, the graphene biointerface treatment of atrioventricular block (the kind of arrhythmia where the electrical conduction from the atria to the ventricles is interrupted) is demonstrated. The graphene arrays show effective electrochemical properties, namely interface impedance down to 40 Ω cm2at 1 kHz, charge storage capacity up to 63.7 mC cm−2, and charge injection capacity up to 704 µC cm−2. Transparency of the graphene structures allows for simultaneous optical mapping of cardiac action potentials, calcium transients, and optogenetic stimulation while performing electrical measurements and stimulation. The report presents evidence of the significant potential of graphene biointerfaces for advanced cardiac electrophysiology and arrhythmia therapy.

As promising hydrogen energy carrier, formic acid (HCOOH) plays an indispensable role in building a complete industry chain of a hydrogen economy. Currently, the biomass upgrading assisted water electrolysis has emerged as an attractive alternative for co‐producing green HCOOH and H2 in a cost‐effective manner, yet simultaneously affording high current density and Faradaic efficiency (FE) still remains a big challenge. Here, the ternary NiVRu‐layered double hydroxides (LDHs) nanosheet arrays for selective glycerol oxidation and hydrogen evolution catalysis are reported, which yield an industry‐level 1 A cm−2 at voltage of 1.933 V, meanwhile showing considerable HCOOH and H2 productivities of 12.5 and 17.9 mmol cm−2 h−1, with FEs of almost 80% and 96%, respectively. Experimental and theoretical results reveal that the introduced Ru atoms can tune the local electronic structure of Ni‐based LDHs, which not only optimizes hydrogen adsorption kinetics for HER, but also reduces the reaction energy barriers for both the conversion of NiII into GOR‐active NiIII and carboncarbon (CC) bond cleavage. In short, this work highlights the potential of large‐scale H2 and HCOOH productions from integrated electrocatalytic system and provides new insights for designing advanced electrocatalyst for low‐cost and sustainable energy conversion.
