Antioxidant and antidiabetic potential of Cystoseira myrica-mediated green metallic zinc nanoparticles using the algal extract: Synthesis and characterization

Abstract Cystoseira myrica marine macroalgae (CSR) were used to produce metallic zinc nanoparticle composites by utilizing the phytochemicals naturally found in the algae. This involves homogenizing the residuals of CSR (10 g), zinc nitrate solution (5 M; 100 mL), and methanol liquid extract (100 mL) at 30 oC for 24 h of sonication and stirring, followed by filtration and drying. This resulted in a hybrid bio-composite (Zn/CSR), which demonstrated strong antioxidant and antidiabetic properties when compared to zinc oxide (ZnO) and CSR used separately. The Zn/CSR hybrid showed excellent antioxidant activity against common radicals such as DPPH (91.5 ± 1.66%), nitric oxide (90.4 ± 1.2%), ABTS (92.2 ± 1.9%), and O2●− (27.8 ± 1.12%) (p < 0.05), performing better than the standard antioxidant, ascorbic acid. Regarding its antidiabetic properties, the Zn/CSR composite significantly inhibited key enzymes involved in diabetes, including both commercial enzyme forms (α-amylase (80.3 ± 1.65%), α-glucosidase (96.6 ± 1.11%), amyloglucosidase (95.8 ± 1.3%)) and their crude intestinal forms (α-amylase (72.3 ± 1.5%), α-glucosidase (94.2 ± 1.7%)) (p < 0.05). This improvement increases the impact of the green CSR extract in reducing the agglomeration behaviors of the loaded metal and the formation of a capping layer from the phytochemicals on its surface, in addition to the beneficial effects of the CSR as substrate, which enhances the biological functions of the loaded metal and its interaction interfaces. The Zn/CSR composite also outperformed commercial miglitol drugs and slightly surpassed acarbose in effectiveness. Given the high cost and potential side effects of current medications, the Zn/CSR composite could be a cost-effective alternative for antioxidant and antidiabetic treatments. These findings also emphasize the role of CSR-derived phytochemicals and algae residues in enhancing the biological activity of the metal nanoparticles

DELirium treatment with Transcranial Electrical Stimulation (DELTES): study protocol for a multicentre, randomised, double-blind, sham-controlled trial.

Delirium, a clinical manifestation of acute encephalopathy, is associated with extended hospitalisation, long-term cognitive dysfunction, increased mortality and high healthcare costs. Despite intensive research, there is still no targeted treatment. Delirium is characterised by electroencephalography (EEG) slowing, increased relative delta power and decreased functional connectivity. Recent studies suggest that transcranial alternating current stimulation (tACS) can entrain EEG activity, strengthen connectivity and improve cognitive functioning. Hence, tACS offers a potential treatment for augmenting EEG activity and reducing the duration of delirium. This study aims to evaluate the feasibility and assess the efficacy of tACS in reducing relative delta power. A randomised, double-blind, sham-controlled trial will be conducted across three medical centres in the Netherlands. The study comprises two phases: a pilot phase (n=30) and a main study phase (n=129). Participants are patients aged 50 years and older who are diagnosed with delirium using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision criteria (DSM-5-TR), that persists despite treatment of underlying causes. During the pilot phase, participants will be randomised (1:1) to receive either standardised (10 Hz) tACS or sham tACS. In the main study phase, participants will be randomised to standardised tACS, sham tACS or personalised tACS, in which tACS settings are tailored to the participant. All participants will undergo daily 30 min of (sham) stimulation for up to 14 days or until delirium resolution or hospital discharge. Sixty-four-channel resting-state EEG will be recorded pre- and post the first tACS session, and following the final tACS session. Daily delirium assessments will be acquired using the Intensive Care Delirium Screening Checklist and Delirium Observation Screening Scale. The pilot phase will assess the percentage of completed tACS sessions and increased care requirements post-tACS. The primary outcome variable is change in relative delta EEG power. Secondary outcomes include (1) delirium duration and severity, (2) quantitative EEG measurements, (3) length of hospital stay, (4) cognitive functioning at 3 months post-tACS and (5) tACS treatment burden. Study recruitment started in April 2024 and is ongoing. The study has been approved by the Medical Ethics Committee of the Utrecht University Medical Center and the Institutional Review Boards of all participating centres. Trial results will be disseminated via peer-reviewed publications and conference presentations. NCT06285721.

Novel optical optode for selective detection and removal of ultra-trace level of mercury ions in different environmental real samples

Owing to the high cost and unavailability of different analytical techniques, there is an urgent need to develop new techniques not only for detecting but also removing mercury ions in real samples. Thus, an optical chemical sensor based on the anchoring of phenanthraquinone monophenylthiosemicarbazone in a plasticized cellulose triacetate membrane was fabricated and applied to the recognition and removal of mercury ions from aqueous solutions. The synthesized optode was characterized by FT-IR, SEM, AFM, and thermal analysis. Several parameters, including the pH, temperature, contact time, washing solvent, and washing time, were optimized. Under optimal conditions, a promising optode film platform was utilized for sensing mercury ions, and the concentrations were calculated based on colorimetric analysis (Histogram, RGB) of digital images, visualization, and spectrophotometry. Also, an optical optode was used for complete adsorption of mercury ions from aqueous solutions. In addition, the regeneration of the synthesized optode was evaluated using 0.1 mol L− 1 nitric acid, which effectively removed all adsorbed mercury ions. The obtained data indicated good linearity in the sensing and adsorption of Hg2+ over a concentration range of 0.005–5000 µgL− 1 with a low limit of detection (LOD = 0.066 µgL− 1) and limit of quantification (LOQ, 0.22 µgL− 1). Furthermore, it showed good distinctions in the presence of coexisting ions, high stability (five months), good applicability, and reproducibility (RSD = 1.31%), making it a promising sensor for Hg2+ detection. On the other hand, the kinetic studies revealed that the pseudo-second-order was the best model for describing the adsorption behavior of mercury ions on the optode surface. Also, the thermodynamic parameters indicate spontaneous (ΔG0 < 0) and endothermic (ΔH0 < 0) reactions. Also, the maximum adsorption capacity was found to be 73.2 mg g− 1. Thus, the optodes were successfully applied for the detection and/or removal of Hg2+ in different real samples, including cucumber, fish, soil, and water samples, with excellent recoveries of 98.1–99.5%.

Health care resource use in preschool children with cerebral palsy.

To estimate the burden of disease and evaluate which factors affect health care resource use (HCRU) in young children with cerebral palsy (CP). Data were collected as part of a prospective, longitudinal cohort study of children with CP born in Queensland, Australia between 2006 and 2009. HCRU questionnaires were administered at six time points. Data on resource use, socio-demographics, and disease severity were collected. Costs were sourced from Medicare, the Australian National Hospital Cost Data Collection, and market prices. A generalized linear model was used to identify factors influencing CP-related costs. A total of 794 questionnaires were completed by 222 participants (mean = 3.6 per participant). Physiotherapy (94%, n = 208) was the most widely accessed allied health care therapy; almost half of the participants (45%; 354 of 794) reported one or more hospital admissions. From the health care funder perspective, a child with CP costs on average A$24 950 per annum (A$12 475 per 6 months). Higher costs were associated with increased motor impairment (Gross Motor Function Classification System, p < 0.001) and increased comorbidities (p = 0.012). HCRU in preschool children with CP can be analysed according to disease severity. Both increased motor impairments and increased comorbidities were associated with higher health care costs. Children with a higher number of comorbidities had higher health care costs, and more specifically, higher hospitalization costs. No significant change in costs was found over time as children aged from 18 months to 5 years.

Dental Coverage for Medicare Beneficiaries.

Poor oral health has been associated with various systemic diseases (e.g., endocarditis, pneumonia, cardiovascular disease, and diabetes) and decreased quality of life. When enacted in 1965, Medicare excluded coverage for comprehensive dental services. As of 2023, Medicare has allowed coverage of limited dental services inextricably linked to specific medical conditions. Many Medicare Advantage plans (Medicare Part C) offer dental coverage. Yet in 2019, approximately 24 million Medicare beneficiaries (47% of all Medicare enrollees), lacked dental coverage. Seventy-one percent of traditional Medicare enrollees (those not enrolled in a Medicare Advantage Plan) reported that high cost was the primary reason that they did not obtain dental care. The importance of oral health for the older adults has been the main reason that a national interprofessional consortium, which includes several national nursing organizations, has been advocating for legislation to expand Medicare to include dental coverage. The consortium's efforts have been thwarted by fierce opposition from the American Dental Association and many Republican legislators. Given the vital role that nurses and advanced practice nurses play in caring for the nation's older adults and disabled, nursing's voice needs to be strengthened as leaders in advocating for inclusion of dental benefits in traditional Medicare.

Survivability and life support in sealed mini-ecosystems with simulated planetary soils

Establishing a sustainable life-support system for space exploration is a formidable challenge due to the vast distances, high costs, and environmental differences from Earth. Building upon the lessons from the Biosphere 2 experiment, we introduce the novel “Ecosphere” and “Biosealed” systems, self-sustaining ecosystems within customizable, enclosed containers. These systems incorporate terrestrial ecosystems and groundwater layers, offering a potential model for transplanting Earth-like biomes to extraterrestrial environments. Over 4 years, we conducted rigorous experiments and analyses to understand the dynamics of these enclosed ecosystems. We successfully mitigated moisture deficiency, a major obstacle to plant growth, by incorporating groundwater layers. Additionally, we quantified microbial communities proliferating in specific soils, including simulated lunar and Ryugu asteroid regolith, enhance plant cultivation in space environments. Metagenomic analysis of these simulated space soils revealed diverse microbial populations and their crucial role in plant growth and ecosystem stability. Notably, we identified symbiotic relationships between plants and Cyanobacteria, enhancing oxygen production, and demonstrated the potential of LED lighting as an alternative light source for plant cultivation in sun-limited space missions. We also confirmed the survival of fruit flies within these systems, relying on plant-produced oxygen and photosynthetic bacteria. Our research provides a comprehensive framework for developing future space life-support systems. The novelty of our work lies in the unique design of our enclosed ecosystems, incorporating groundwater layers and simulated extraterrestrial soils, and the detailed analysis of microbial communities within these systems. These findings offer valuable insights into the challenges and potential solutions for establishing sustainable human habitats in space, including the importance of microbial management and potential health concerns related to microbial exposure.

Assessment of Early Vascular Aging Ambulatory Score (EVAAs): A Large Population-based External Validation Study.

Pulse Wave Velocity (PWV) remains the gold-standard method to assess Early Vascular Aging (EVA) defined by arterial stiffness. However, its high cost, time-consuming process, and need for qualified medical staff shows the importance of identifying alternative methods for the EVA evaluation. In order to simplify the process of assessing patients' EVA, we recently developed the Early Vascular Aging Ambulatory score (EVAAs), a simple tool to predict the risk of EVA. The aim of the present study was the external validation of EVAAs in an independent population. Eight hundred seventy-nine (46.3% men) patients who were referred to our Hypertension ESH Excellence Center were included in this study. The mean age was 46.43 ± 22.87 years. EVA was evaluated in two different ways. The first assessment included c-f PWV values, whereas the second one included EVAAs without the direct measurement of carotid-femoral PWV. The null hypothesis was that the prediction of EVA based on EVAAs does not present any statistically significant difference compared to the prediction based on the calculation from c-f PWV. Mean squared error (MSE) was used for the assessment of the null hypothesis, which was found to be 0.40. The results revealed that the EVAAs show the probability of EVA with 0.98 sensitivity and 0.75 specificity. The EVAAs present 95% positive predictive value and 92% negative predictive value. Our study revealed that EVAAs could be as reliable as the carotid-femoral PWV to identify patients with EVA. Hence, we hope that EVAAs will be a useful tool in clinical practice.

Design of an innovative aptasensor for the detection of chemotherapeutic drug Fludarabine phosphate

Monitoring the concentration of Fludarabine phosphate, a standard chemotherapeutic drug widely used in cancer treatment, is vital for ensuring the drug’s safety and effectiveness, tailoring treatments to individual needs, and consequently improving overall patient outcomes. Regarding the limitations of conventional techniques in terms of complexity, large time measurements, and a high cost, there is an urgent need to develop simple, rapid, and cost-effective devices. In this paper, we report the design of an aptasensor for the specific and selective detection of Fludarabine. Systematic evolution of ligands by exponential enrichment (SELEX) protocol was performed to select a specific aptamer for Fludarabine. Eleven rounds were carried out, and nine sequences were selected. Based on the dissociation constant (Kd), Ful-3, exhibiting the highest affinity (18.86 nM), was chosen and integrated into a simple electrochemical aptasensing platform for Fludarabine detection. Electrochemical results demonstrated good performance of the selected aptamer in detecting Fludarabine within the analytical range of 1 to 150 pg/mL and with LOD and LOQ in the order of 0.11 pg/mL (0.31 fM) and 0.39 pg/mL (1.06 fM), respectively. The developed platform also showed good selectivity against different analogous molecules and high applicability in serum-spiked samples, with recovery percentages ranging from 96.81 to 99.04%. Considering the encouraging results, this research presents an excellent alternative in terms of simplicity, stability, ease of use, reduction of sample volume, and low cost.

Healthcare Service Utilization and Related Costs. A Comparison of the Situation of Persons With Spinal Cord Injury to the General Population.

The aim of the study is to investigate healthcare utilization and related costs in spinal cord injury compared to the Swiss population, addressing gaps in understanding this vulnerable group's needs. We analyzed healthcare utilization across age groups using data from the Swiss Health Survey and the Swiss Community Survey. Employing count models, Zero-Inflated Negative Binomial, and Poisson regressions, we estimated the adjusted healthcare visits across different age groups in the sample. Persons with spinal cord injury use 11 times more healthcare services than the healthy population and 4 times more than persons with other chronic health conditions. Notably, service providers for persons with spinal cord injury include physiotherapists, nursing services, general practitioners, and specialists. The high frequency of usage of persons with spinal cord injury translates into high costs, which is 3 times higher than in the general healthy population. These patterns become more evident as persons with spinal cord injury age, where nursing care and rehabilitation services become the most demanded services. Our findings show the multiple healthcare needs of people with spinal cord injury, which makes them a high-needs, high-cost group. This characteristic underscores the importance of preventive measures to reduce the incidence of spinal cord injury in older adults.

Oral sildenafil versus bosentan for treatment of persistent pulmonary hypertension of the newborn: a randomized controlled trial

BackgroundAccess to inhaled nitric oxide (iNO) is limited in low resource settings due to non-availability and high cost. There is a need for research on low-cost alternative therapies for management of persistent pulmonary hypertension of the newborn (PPHN). We aimed to compare oral sildenafil and bosentan as monotherapy in the treatment of neonates with PPHN.Study designIn this single-centre open-label randomized controlled trial (RCT), term and late preterm neonates with PPHN, defined as pulmonary arterial systolic pressure (PASP) > 35 mmHg and requiring fraction of inspired oxygen (FiO2) > 0.21, were randomized to receive oral sildenafil and bosentan. The primary outcome was reduction of PASP by 25% within 48 h after start of drug.ResultsThirty-six neonates were analyzed (18 in each group). Initial PASPs were similar in both groups. The median (IQR) time for the primary outcome (PASP to reduce by 25% within 48 h) was 36 (24–48) h and 96 (48–120) h in sildenafil and bosentan groups respectively (p = 0.008). There was also a higher need to add other pulmonary vasodilators in bosentan group as compared to sildenafil group (p = 0.006).ConclusionSildenafil was associated with quicker reduction of PASP and FiO2 in neonates with PPHN, as compared to bosentan. Large multicentre blinded trials to assess efficacy and safety of bosentan in comparison with other pulmonary vasodilators would help to get a clearer understanding of its role in the management of PPHN, particularly for use in resource-limited settings that lack iNO.Clinical trial registration:https://ctri.nic.in/Clinicaltrials/rmaindet.php? trialid=63997&EncHid=39716.16132&modid=1&compid=19[CTRI/2022/06/043328].

Decoding Scholarcy website: A Study on its Research Summarization Efficiency

The development of artificial intelligence (AI) has revolutionized various facets of education, particularly the research domain. With the rapid growth of scholarly literature, the need for an efficient tool for summarization has become increasingly paramount. This study proposes a quantitative investigation into the efficiency of Scholarcy (www.scholarcy.com), an AI-powered summarizer used to aid researchers in summarizing academic literature. Thirty-five postgraduate students were involved in a survey research design. After five weeks of using Scholarcy, participants were asked to complete a survey questionnaire via their email addresses to give feedback on this tool. The results indicated a positive reception when postgraduates found this AI summarizer convenient and useful for reading academic papers. On the other hand, the participants identified several drawbacks when using it including concerns about summary quality, the absence of a mobile application, and high cost, along with suggestions for further application. With the highlights of both benefits and limitations, the study hopes to contribute valuable insights into the development of AI-powered summarization tools in the future.

Investigation into the purification and regeneration of rare earth polishing powder waste via continuous solid-phase conversion

The concentration of rare earth elements (lanthanum, cerium, and praseodymium) within rare earth polishing powder waste (REPPW) typically exceeds 50 %, with the majority of impurities comprised of silicon and aluminum-related compounds. Transforming REPPW into recycled rare earth polishing powders that adhere to polishing standards in an eco-friendly and economically viable way presents a significant challenge in the industry. Traditional acid or alkaline processes predominantly recover rare earth elements as oxides, which are underutilized due to their high costs. Considering the varying forms of impurities and rare earth compounds found in REPPW, this research introduces a novel physicochemical decontamination and continuous chemical transformation process aimed at producing regenerated rare earth polishing powders. Under optimal conditions, the physicochemical two-step decontamination process achieved a rare earth recovery rate surpassing 92 %, while silicon and aluminum removal rates reached 86.12 %. During the continuous chemical transformation of REPPW, the rare earth phases in an alkaline setting followed the sequence REOF (CeO2) → RE(OH)3 → RECO3OH→RECO3F→CeLa2O3F3(CeO2), which not only facilitated phase reorganization but also enhanced the particle surface structure. Notably, these chemical transformations did not disrupt the rare earth distribution; instead, they indirectly boosted product purity and uniformly dispersed within the regenerated polishing powder particles, thereby improving polishing efficiency. Consequently, the adoption of this innovative regeneration process for polishing powders holds substantial importance for the sustainable utilization of rare earth resources.

Actual clinical practice pattern in SWL after COVID-19 era: a critical evaluation from different aspects.

To outline the current status of Shock Wave Lithotripsy (SWL) in stone treatment and the changes in the mode of application after the COVID-19 pandemic along with critical factors affecting the clinical practice of this particular procedure. This study targeted national and international urology experts who could share and contribute their experiences and perspectives on SWL practices after COVID-19 era. Approximately 650 urology specialists were invited to participate in the survey based study via Google Forms. Participation was voluntary and 398 of the invited participants completed the survey, yielding an acceptable response rate of approximately 61.23%. This survey highlights significant findings that shed light on the changes in clinical SWL applications. Nearly half of SWL procedures are performed by technicians or nurses instead of experienced urologists, potentially affecting the proper application and outcomes of the procedure. SWL seemed to be applied on a guideline (GL) indications based manner by the majority of the participants. Fluoroscopy remains still as the most commonly used method for radiological assessment, underscoring the necessity to teach sonography applications to younger urologists. Key reasons for the limited clinical application of SWL include the absence of lithotripters in the departments, high lithotriptor costs and significantly lower reimbursement rates compared to PNL and fURS modalities. Finally, an increase in SWL utilization rates has been observed post-COVID-19, highlighting its certain advantages realized during this period. These findings provide important insights into the role of SWL in stone treatment and the main factors influencing its clinical application practices. Although the popularity of SWL in the management of urinary stones is being stated to decline particularly in the last two decades, data obtained in this survey emphasized well that it is still a viable option especially for stones smaller than 15mm. Our findings highlight the enduring relevance of SWL in contemporary stone therapy protocols in the context of COVID-19, where outpatient, non-invasive procedures are preferred. In addition to the consideration of certain factors affecting the rate of its application in clinical practice, to achieve high success rates with minimal complications in SWL, strategic patient selection and adherence to procedure guidelines seem to be crucial.

Type-II heterojunction Se-g-C3N4/ZnO coupled MnCo2O4 photocatalyst for enhanced levofloxacin hydrochloride degradation activated by peroxymonosulfate

The advanced oxidation process induced by photocatalysis under visible light undoubtedly possesses greater application potential and cost-effectiveness due to the high excitation energy supply costs. Here, we proposed a novel Type-II heterojunction Se-g-C3N4/ZnO (Se-CN/ZnO) and MnCo2O4 (MCO) photocatalyst for the efficient degradation of levofloxacin hydrochloride (LEV) activated by peroxymonosulfate (PMS) under sunlight. Analysis results confirmed the oxidation process was executed by Se-CN/ZnO synergistic MCO-activated PMS for the responsive degradation of LEV, achieving a removal efficiency greater than 98.6 % within 15 min (kinetic rate constant Kobs = 0.299 min−1), under optimal conditions ([Se-CN/ZnO (300 °C)]0 = 46 mg, [MCO]0 = 1.6 mg, [PMS]0 = 0.27 mM, [Aeration rate]0 = 146 mL/min, pH = 5.5). Effective interfacial transfer and spatial segregation of the photogenerated electron-hole were attributed to the stabilized Type-II energy band structure of Se-CN/ZnO, the rapid cyclic redox of metal ions Mnn+(n = 2,3,4) and Com+(m = 2,3) promoted the activation of PMS reduction of LEV through synergistic action of various endogenous substances. Analysis of the contribution of reactive oxygen species by electron paramagnetic resonance substantiated the dominant role of ·OH and O2·-, and the superiority of the degradation process was further validated with the analysis of the non-toxic and ecological safety characteristics of intermediates. The recommended method of eco-friendly and stable catalytic performance of LEV has engineering application prospects that are incomparable to many publicly available treatment methods.

Correlating the microstructure of titanium hydride with its hydrogenation conditions via thermodynamics and kinetics

Titanium hydride is widely considered as an important hydrogen storage material due to its high capacity, stability and low cost. The microstructure of titanium hydride, which is usually induced by the hydrogenation of titanium, strongly influences its storage performance. However, the relationship between the hydrogenation conditions and the derived microstructure of titanium hydride is still unclear, limiting the development of its structure design strategy. In this work, the microstructure of titanium hydride is correlated with its hydrogenation conditions through the thermodynamics and kinetics. By evaluating the effect of the hydrogenation temperature, pressure and cooling rate, three classes of the hydrogenation processes were clarified as kinetic-limited, continuous and stepwise. Besides, according to the SEM and FIB-STEM results, these different processes are confirmed to greatly vary the bulk microstructure. It is concluded that a fast and continuous transition induces a broken bulk morphology, while a stepwise process leads to a larger bulk grain size. In summary, this study presents a framework for designing titanium hydride structures by modifying phase transition processes through careful adjustment of hydrogenation parameters, namely, a condition-process-structure relationship. This relationship offers crucial guidance in managing the grain refinement or coarsening of hydrides within hydrogen storage components and metallurgical applications.

Settling for a “good enough” school: contradictions of middle class reproduction in a small town in illiberal Hungary

Abstract The politics of the Orbán regime, in power in Hungary since 2010, are reshaping the possibilities for middle class reproduction and social mobility, as revealed through our analysis of parental dilemmas around school choice and future aspirations in a peripheral small town. As the main targets of re-industrialization and an important voter base for the regime, small towns are particularly relevant localities for studying the transformations of middle-class reproduction. Globally, anxieties over class reproduction pushes parents to invest more intensely in their children’s education, whereas increasingly worrying about the detrimental effects of related pressures on their child’s well-being. In small towns in the global semi-periphery, parental dilemmas around schooling appear in a particularly acute form due to the limited possibilities for social advancement, the high financial and emotional costs that mobility requires, and the racialised dimension of localised class relations. We contend that policies of the Orbán regime, such as the ‘churchification’ of education and the privileging of technical middle schools, have further reshaped local possibilities and routes of advancement. The tension between the pervasive promise of middle-class advancement through education and the locally rooted assessment of realistic employment possibilities exposes the contradictions of the current regime and helps to grasp the localised consequences of its socio-economic re-engineering. As in the studied context class is strongly racialised, we examine the strategies and dilemmas of middle class parents of the ethnic majority, and Roma parents who aspire to become middle class in a relational way, revealing how ethnicity further complicates middle class reproduction in Hungarian peripheral small towns.

Inclusive Exploration of Harmonizing and Alternative Treatments for Hypothyroidism

: A clinical syndrome known as hypothyroidism occurs due to a shortage of thyroid hormone as a result of decreased production, abnormal distribution, or no action of thyroid hormones. The most typical clinical symptoms included are dry skin, hair loss, weight gain, painful-prolonged periods, infertility, balance problems, slow speech, bradycardia, hypothermia, fatigue, anxiety &amp; depression, joint pain, and indigestion. Basically, age, gender, the severity of the ailment, and a few other factors affect the various signs and symptoms of hypothyroidism. The limitations of allopathic modalities necessitate the investigation of alternative treatment options. Future healthcare initiatives for the poor world will increasingly depend on CAM approaches to these concerns because lifestyle, diet, obesity, lack of exercise, and stress are significant contributing factors to the development of hypothyroidism. This review's objective is to provide information on herbs as well as complementary and alternative medications which are grouped into five major domains: Biologically Based therapies, Manipulative body-based therapies, Mind body-based therapies, and the whole Medical system. These have traditionally been used to treat thyroid dysfunction. The distribution of diseases in emerging nations is altering as a result of globalization. Hence the existing and potential roles of CAM techniques in the general practice of medicine are illustrated in these approaches. Scientists are being compelled to consider traditional herbal medical treatments and CAM therapy in order to combat adverse medication occurrences, high treatment costs, and compliance problems thus described in this review paper.

High-performance α-Fe2O3 nano cubes as anode for supercapacitors

Abundant availability, high theoretical specific capacitance and low cost of transition metal oxides such as iron oxides, make them attractive as electrode materials for energy storage. In order to achieve improved performance, high conductivity, shorter ion-diffusion path, and faster ion accessibility, rational design of morphology of electrode material is highly desirable. We have successfully synthesized mesoporous α-Fe2O3 nanocubes to achieve high specific capacitance and better retention. The as-prepared and annealed α-Fe2O3 nanocubes show high reversible redox activity along with good thermodynamic stability. These nanostructure give rise to high specific capacitance and ~90 % of the capacitance can be retained even after 1000 redox cycles, suggesting good cyclic stability. The electrochemical performance of mesoporous α-Fe2O3 nanocubes is attributed to the morphological features, which results in efficient K+ ion transport into the pores. A two electrode α-Fe2O3//NiO device is fabricated, which shows excellent power and energy density of ∼627 W/kg and ∼23.32 Wh/kg, respectively. Our work demonstrates that 3D nanoporous α-Fe2O3 electrodes forms promising material system as anode for improved charge storage performance.

Recyclable VOCs-free eutectic adhesive based on hydrogen bond fusion strategy with robust adhesion, flame retardancy, transparency, high durability, and low-temperature resistance

Although emerging supramolecular adhesives have addressed the challenge of traditional adhesives in terms of de-bonding through non-covalent interactions, they still face issues such as high synthetic difficulty, elevated costs, and inadequate adhesion strength, particularly under low temperatures. Additionally, achieving robust adhesion to low-energy hydrophobic surfaces remains a persistent challenge. This paper proposes a novel hydrogen bond fusion strategy to address these challenges, presenting the synthesis of a new HCX eutectogel, containing intramolecular fused hydrogen bonds and intermolecular hydrogen bonds. This approach enables the attainment of high-strength adhesion on both hydrophilic (up to 10.61 MPa) and hydrophobic (up to 4.87 MPa) substrates. Notably, the HCX eutectogel stands out for its ability to maintain stable adhesion performance at low temperatures (−80 °C & liquid nitrogen) and its extraordinary flame retardancy and recyclability. These findings contribute novel insights into the development of high-performance adhesives with multifunctionality, promising advancements in diverse applications.

Renewable energy in sustainable cities: Challenges and opportunities by the case study of Nusantara Capital City (IKN)

Indonesia's future IKN capital might be sustainable, low-carbon, and climate-resilient. The Low Emissions Analysis Platform (LEAP) simulates energy efficiency in various demand sectors, renewable energy, and sustainable transportation solutions. Sustainable cars, such as renewable-energy-powered electric and green hydrogen-powered vehicles, can reduce energy consumption by 43% in 2045 and 33% in 2060, respectively, compared to BAU. GHG emissions per capita will drop 70% in 2045 and 63% in 2060. In the net-zero emission (NZE) scenario, IKN can reach 100% green energy by 2045 with a 4.4 GW solar power plant, a 0.92 GWh BESS, and a full load hour capability of 4 hours. We will use 1.1 GW of hydropower and 143 MW of wind power by 2045. In 2060, hydropower will be 2.8 GW, wind power will be 184 MW, and solar power will be 8 GW with 1.6 GWh of BESS. Lack of legislation, technical expertise, high prices, inadequate grid infrastructure, and insufficient renewable electricity restrict BESS use in Indonesia. Solar energy installation requirements, subsidies, and off-grid project incentives can all help ease BESS use. Forecasts predict 0.53 GW of rooftop solar PV capacity by 2045 and 3.35 GW by 2060. Net metering and solar tariffs boost rooftop solar system profitability. One ton of green hydrogen production requires 55.7 MWh from a solar power plant. Solar power plant capacity will rise to 0.49 GW by 2045, producing 19,359 tons of green hydrogen, and almost quintuple to 89,594 tons by 2060. Hydrogen generation, storage, transit, and distribution require specific infrastructure due to high capital costs and a lack of networks, yet interest in them is growing.
