Examining characteristics of those who receive pedorthic services: A clinical audit.

Diabetes-related foot complications, including neuropathic plantar forefoot ulcers, are a significant contributor to morbidity and increased healthcare costs. This retrospective clinical audit examines the characteristics of people accessing pedorthics services who are at risk of neuropathic plantar forefoot ulcer (re)occurrence and the pathways and funding models used to access these services. A clinical record audit was conducted on all patients accessing a pedorthics service who had diabetes and neuropathy with a history of plantar forefoot ulceration. The data included demographics, diabetes and neuropathy duration, main forefoot pathology and other comorbidity, footwear and insole interventions, and health fund access status. A total of 70 patient records were accessed, and relevant data was extracted. The mean age of participants was 64.69 (standard deviation (SD) 11.78) years; 61% were male and 39% female. Duration of diabetes ranged from one to 35 years, with a mean of 14.09 years (SD 6.58). The mean duration of neuropathy was 8.56 (SD 4.16) years. The most common forefoot conditions were bony prominences at 71% (n = 50), rigid flat foot and limited joint mobility (53%, n = 37), and hallux abductovalgus at 47% (n = 33). All participants had hyperkeratosis; 34% (n = 24) had forefoot amputation, and around 34% (n = 24) had a history of digital amputation. Various publicly funded packages and private health insurance were accessed. This study investigates the sociodemographic and medical profiles of individuals with diabetes-related foot complexities prone to neuropathic plantar forefoot ulcers. It is the first to examine patients receiving pedorthic services, informing practitioner surveys and preventive care strategies. Understanding patient characteristics aids in optimising multidisciplinary care and reducing ulcer incidence. Further studies are warranted to explore the field to establish an effective multidisciplinary care approach between medical professionals, podiatrists and pedorthists to optimise patient outcomes.

Phytochemical analysis, and antioxidant and hepatoprotective activities of Chamaerops humilis L. leaves; a focus on xanthine oxidase.

Chamaerops humilis L. is clumping palm of the family Arecaceae with promising health-promoting effects. Parts of this species are utilized as food and employed in folk medicine to treat several disorders. This study investigated the phytochemical constituents of C. humilis leaves and their antioxidant and xanthine (XO) inhibitory activities in vitro and in acetaminophen (APAP)-induced hepatotoxicity in rats. Eleven compounds were isolated from C. humilis ethanolic extract (CHEE). CHEE and the butanol, n-hexane, and dichloromethane fractions exhibited in vitro radical scavenging and XO inhibitory efficacy. The computational findings revealed the tendency of the isolated compounds towards the active site of XO. In vivo, CHEE ameliorated liver function markers (ALT, AST, ALP, and albumin) and prevented tissue injury induced by APAP in rats. CHEE suppressed hepatic XO, decreased serum uric acid and liver MDA, and enhanced GSH, SOD, and catalase in APAP-treated rats. CHEE ameliorated serum TNF-α and IL-1ß in APAP-treated rats. Thus, C. humilis is rich in beneficial phytochemicals that possess binding affinity towards XO. C. humilis exhibited potent in vitro antioxidant and XO inhibitory activities, and prevented APAP hepatotoxicity by attenuating tissue injury, oxidative stress and inflammation.

Short-term photovoltaic energy generation for solar powered high efficiency irrigation systems using LSTM with Spatio-temporal attention mechanism.

Solar irrigation systems should become more practical and efficient as technology advances. Automation and AI-based technologies can optimize solar energy use for irrigation while reducing environmental impacts and costs. These innovations have the potential to make agriculture more environmentally friendly and sustainable. Solar irrigation system implementation can be hampered by a lack of technical expertise in installation, operation, and maintenance. It must be technically and economically feasible to be practical and continuous. Due to weather and solar irradiation, photovoltaic power generation is difficult for high-efficiency irrigation systems. As a result, more precise photovoltaic output calculations could improve solar power systems. Customers should benefit from increased power plant versatility and high-quality electricity. As a result, an artificial intelligence-powered automated irrigation power-generation system may improve the existing efficiency. To predict high-efficiency irrigation system power outputs, this study proposed a spatial and temporal attention block-based long-short-term memory (LSTM) model. Using MSE, RMSE, and MAE, the results have been compared to pre-existing ML and a simple LSTM network. Moreover, it has been found that our model outperformed cutting-edge methods. MAPE was improved by 6-7% by increasing Look Back (LB) and Look Forward (LF). Future goals include adapting the technology for wind power production and improving the proposed model to harness customer behavior to improve forecasting accuracy.

Exploring the nexus between FDI inflows and economic growth: A sectoral level analysis.

This study investigates the relationship between Foreign Direct Investment (FDI) inflows and economic growth at sectoral levels in Bangladesh, employing a panel study framework. Utilizing sectoral-level panel data spanning six sectors from 2007-08 to 2018-19, the analysis is conducted using Panel Vector Error Correction Model (Panel VECM). Results from panel unit root tests confirm that all variables are integrated of order one I (1), indicating stationarity. The Pedroni panel co-integration test further supports the presence of co-integration among the variables. Notably, the Panel VECM reveals evidence of a unidirectional causal relationship from Real Gross Domestic Product (RGDP) to Real Foreign Direct Investment (RFDI) across all six sectors of Bangladesh. The findings underscore the significance of formulating pragmatic policies and implementing them effectively to attract FDI across sectors, thereby contributing to the overall economic growth of Bangladesh.

Investigating the crowding effect of FDI on domestic investments: Evidence from Bangladesh.

This study empirically investigates the crowding effect of Foreign Direct Investment (FDI) on domestic investments in Bangladesh, utilizing annual time series data from 1972 to 2022. Initially, unit root tests are conducted with and without considering structural breaks in the dataset. This study employs the Johansen test of cointegration to investigate the enduring association between the variables and utilizes the Vector Error Correction Model (VECM) to accommodate this relationship over the long term. Following the estimation of the VECM, formulas about the magnitude of the crowding effect (CE) are applied to examine the impact of FDI on domestic investment in Bangladesh. Results indicate that FDI positively influences domestic investments in both the short and long run.

Grey water footprint for evaluating Zefta wastewater treatment plant: a case study.

The numbers of wastewater treatment plants (WWTP) in Egypt are increasing, yet the general level of pollution associated with wastewater discharge after treatment has not been evaluated. Grey water footprint (GWF) was used to assess the effluent discharges from Zefta WWTP. GWF, before and after treatment, was calculated and followed up to determine its impact on the receiving freshwater body. 150 samples were collected and analysed for BOD5 to determine the optimum operating conditions. Averages values were DO = 2.2, SV30 = 500, SVI = 167, SA = 9.3 d, MLVSS = 2392 mg/L, f/m = 0.16, MLSS in RAS = 7922 mg/L, WAS = 140 m3/d and the HRT = 12 h. The removal efficiency of COD and TSS in the primary settling tank reached 39% and 69%, respectively. Average calculations of removal efficiency percentile reached 90-93%. Average freshwater quantities required to reduce pollutants in the receiving body stream were seasonally determined for Zefta WWTP as 5.3 × 107 m3/year. The average influent BOD5 was 376 mg/L, it was reduced to 47 mg/L in the effluent, wherever the Cmin is 6 mg/L and Cnat is 10 mg/L. Statistical analysis has shown a significant direct relation between ΔWFG,mef and WFG,ref reached 0.952 and a significant inverse relation with Cef -0.982. WFG,T has shown a significant direct relation with Cr 0.974. WFG,T- ref has shown a significant direct relation with Cr as 0.971 and WFG,T as 0.803. It can be concluded that ΔWF is effective in evaluating the efficiency of wastewater treatment and its effect on the quality of receiving water bodies.

Immunological Signatures in Blood and Urine in 80 Individuals Hospitalized during the Initial Phase of COVID-19 Pandemic with Quantified Nicotine Exposure.

This research analyzes immunological response patterns to SARS-CoV-2 infection in blood and urine in individuals with serum cotinine-confirmed exposure to nicotine. Samples of blood and urine were obtained from a total of 80 patients admitted to hospital within 24 h of admission (tadm), 48 h later (t48h), and 7 days later (t7d) if patients remained hospitalized or at discharge. Serum cotinine above 3.75 ng/mL was deemed as biologically significant exposure to nicotine. Viral load was measured with serum SARS-CoV-2 S-spike protein. Titer of IgG, IgA, and IgM against S- and N-protein assessed specific antiviral responses. Cellular destruction was measured by high mobility group box protein-1 (HMGB-1) serum levels and heat shock protein 60 (Hsp-60). Serum interleukin 6 (IL-6), and ferritin gauged non-specific inflammation. The immunological profile was assessed with O-link. Serum titers of IgA were lower at tadm in smokers vs. nonsmokers (p = 0.0397). IgM at t48h was lower in cotinine-positive individuals (p = 0.0188). IgG did not differ between cotinine-positive and negative individuals. HMGB-1 at admission was elevated in cotinine positive individuals. Patients with positive cotinine did not exhibit increased markers of non-specific inflammation and tissue destruction. The blood immunological profile had distinctive differences at admission (MIC A/B↓), 48 h (CCL19↓, MCP-3↓, CD28↑, CD8↓, IFNγ↓, IL-12↓, GZNB↓, MIC A/B↓) or 7 days (CD28↓) in the cotinine-positive group. The urine immunological profile showed a profile with minimal overlap with blood as the following markers being affected at tadm (CCL20↑, CXCL5↑, CD8↑, IL-12↑, MIC A/B↑, GZNH↑, TNFRS14↑), t48h (CCL20↓, TRAIL↓) and t7d (EGF↑, ADA↑) in patients with a cotinine-positive test. Here, we showed a distinctive immunological profile in hospitalized COVID-19 patients with confirmed exposure to nicotine.

Protective Effects of Propolis and Chitosan Nanoparticles against Ibuprofen-Induced Hepatotoxicity in Albino Rats.

Post-marketing hepatotoxicity findings are more common or occur much later. NSAIDs (non-steroidal anti-inflammatory drugs) like ibuprofen are consumed in large quantities around the world. NSAIDs have a low incidence of hepatotoxicity but their wide use makes them a major contributor to drug-induced liver injury. Hepatitis is linked to systemic oxidative stress which results in cellular necrosis and fibrosis, as well as tissue lipoprotein peroxidation and glutathione depletion. Given the lack of safe and effective anti-hepatitis drugs in medicine today, natural substances appear to be a promising and safe alternative. Propolis and chitosan are considered natural substances that have a protective effect on the hepatocytes. The purpose of this study was to validate the protective effect of propolis/chitosan nanoparticle extracts on ibuprofen-induced hepatotoxicity. Thirty (30) albino rats were used for the experiment. Animals were exposed to ibuprofen (400 mg/kg body weight/day) for 4 weeks (7 days/week) followed by treatment with propolis (200 mg/kg body weight/day) and chitosan extract (200 mg/kg body weight/day) separately and also in combination for consecutive 4 weeks. This study revealed a significant increase in serum transaminases, alkaline phosphatase, albumin, and total bilirubin in serum, as well as an increase in lipid peroxidation (MDA) and nitric oxide (NO). Furthermore, GSH, GST, and SOD decreased significantly in the group that was exposed to ibuprofen. Furthermore, there was a significant increase in pro-inflammatory parameters such as IL-1ß and NF-ĸB, as well as low levels of anti-inflammatory parameters such as IL-6 and BCl-2. These alterations were improved by propolis and chitosan extracts, which was further confirmed in experimental animals. This study demonstrated that propolis and chitosan nanoparticle extracts have the potential to protect against hepatotoxicity induced by ibuprofen, due to their ability to regulate anti-inflammatory and anti-oxidative defense activities.

A smart medicine reminder kit with mobile phone calls and some health monitoring features for senior citizens.

The demand for an effective system that combines cutting-edge technologies with medical research to improve healthcare systems has increased with the development of medical technology. The most fundamental form of disease prevention is taking the right medication when needed. With the right care, many fatal diseases can be cured or prevented. Therefore, it is crucial to follow the doctor's recommended drug plan. Healthcare experts now have serious concerns about patients not being able to take their prescribed medications on time, particularly elderly patients. Due to age-related memory loss, people who have been given multiple prescriptions at once over an extended period of time are more likely to forget to take their medication on time or to take the wrong medication. Sometimes, a patient's inability to take the right medication at the right time might have a major impact on their health. Aside from being forgetful, patients, especially the elderly and illiterate, may not be able to read the name stated on medical containers, leading to the consumption of the wrong medication. These errors contribute to non-adherence to pharmaceuticals, which is detrimental to the patient's health. As a result, there is a significant problem that hinders the success of the treatment. The medication reminder system is intended for people who frequently take medications or vitamin supplements in order to handle this. In order to help an elderly person properly take their medication and help the patient have a healthy life, we have created a ground-breaking portable multifunctional medicine reminder kit with phone calls. Other intelligent characteristics of the smart medicine reminder include the capacity to show the time, date, and day in real time, the detection of smoke, the measurement of air humidity and temperature in the room, the measurement of heartbeats per second, the patient's body temperature, and the oxygen saturation level.

Identification of broken conductor faults in interconnected transmission systems based on discrete wavelet transform.

Interconnected transmission systems are increasingly spreading out in HV networks to enhance system efficiency, decrease reserve capacity, and improve service reliability. However, the protection of multi-terminal lines against Broken Conductor Fault (BCF) imposes significant difficulties in such networks as the conventional distance relays cannot detect BCF, as the BCF is not associated with a significant increase in current or reduction in voltage Traditionally, the earth fault relays in transmission lines may detect such fault; Nonetheless, it suffers from a long delay time. Moreover, many of the nearby earth fault relays detect the BCF causing unnecessary trips and badly affecting the system stability. In this article, a novel single-end scheme based on extracting transient features from current signals by discrete wavelet transform (DWT) is proposed for detecting BCFs in interconnected HV transmission systems. The suggested scheme unit (SSU) is capable of accurately detecting all types of BCFs and shunt high impedance faults (SHIFs). It also adaptively calculates the applied threshold values. The accurate selectivity in multi-terminal lines is achieved based on a fault directional element by analyzing transient power polarity. The SSU discriminates between internal/external faults effectively utilizing the time difference observed between the first spikes of aerial and ground modes in the current signals. Different fault scenarios have been simulated on the IEEE 9-Bus, 230 kV interconnected system. The achieved results confirm the effectiveness, robustness, and reliability of SSU in detecting correctly BCFs as well as the SHIFs within only 24.5 ms. The SSU has confirmed its capability to be implemented in interconnected systems without any requirement for communication or synchronization between the SSU installed in multi-terminal lines.

Cocaine-Induced Bilateral Internal Carotid Artery Dissection: A Case Report.

Internal carotid artery dissection is a rare vascular condition with potentially life-threatening consequences, often resulting in intramural hematomas and luminal narrowing. Various etiological factors, including cocaine use, contribute to its occurrence. This case report explores a striking instance of bilateral internal carotid artery dissection in a middle-aged man with a history of chronic cocaine use, shedding light on the intricate relationship between substance abuse and vascular pathology. We present the case of a 47-year-old man with a significant history of chronic cocaine use presented with sudden-onset severe headaches and visual disturbances, including blurred vision and diplopia. Physical examination revealed signs of Horner's syndrome and neurological involvement. Diagnostic imaging confirmed bilateral internal carotid artery dissections, primarily on the right side, with mural hematoma formation and luminal narrowing. Immediate management included pain control, blood pressure regulation, and discontinuation of cocaine use. The patient's symptoms gradually resolved with anticoagulation therapy, and he was discharged with a comprehensive follow-up plan. This case of bilateral internal carotid artery dissection in a middle-aged man with a history of chronic cocaine use underscores the intricate relationship between this condition and substance abuse. It highlights the need for a comprehensive clinical history to identify potential links between substance use and vascular pathologies. The multidisciplinary approach to diagnosis and management is crucial in optimizing patient outcomes. Addressing substance abuse as a contributing factor to vascular pathology is essential, emphasizing the importance of comprehensive care and support for affected individuals, and contributing valuable insights to the existing literature on vascular pathology.

Advanced Equilibrium Studies for the Synergetic Impact of Polyaniline on the Adsorption of Rhodamine B Dye by Polyaniline/Coal Composite.

The synergetic improvement effect of the polyaniline (PANI) hybridization process on the adsorption of rhodamine B dye (RB) by PANI/coal hybrid material (PANI/C) has been evaluated using both traditional equilibrium modeling and advanced isotherm investigations. The composite was prepared by polymerizing polyaniline in the presence of coal fractions with a surface area of 27.7 m2/g. The PANI/C hybrid has an improved capacity to adsorb RB dye (423.5 mg/g) in comparison to coal particles (254.3 mg/g). The maintained increase in the elimination properties of PANI/C has been illustrated using the steric characteristics of active site density (Nm) as well as the total number of adsorbed RB on a single active site (n). However, the incorporation of PANI did not yield any substantial impact on the existing active sites' quantity, but the hybridization processes greatly influenced the selectivity and affinity of each active site, in addition to the aggregation characteristics of the dye as it interacts with the composite's surface. Whereas raw coal can only adsorb three molecules of RB, each active site throughout the PANI/C surface can adsorb approximately eight RB molecules. This is also evidence of RB dye adsorption in a vertical arrangement, which involves multimolecular processes. The Gaussian energy (4.01-5.59 kJ/mol) and adsorption energy (-4.34-4.68 kJ/mol) revealed the controllable impact of physical mechanisms. These mechanisms may include van der Waals forces, dipole-dipole interactions, and hydrogen bonds (<30 kJ/mol). The thermodynamic functions, such as enthalpy, internal energy, and entropy, that have been assessed provide evidence supporting the exothermic and spontaneous nature of the RB uptake processes by PANI/C.

Sex and national differences in internet addiction in Egypt and Saudi Arabia.

BACKGROUND: Understanding individual differences in psychology, and how they relate to specific addictions, may allow society to better identify those at most risk and even enact policies to ameliorate them. Internet addiction is a growing health concern, a research focus of which is to understand individual differences and the psychology of those most susceptible to developing it. Western countries are strongly overrepresented in this regard. METHOD: Here, sex and national differences in internet addiction are measured, using Young's 'Internet Addiction Test,' in two non-Western countries, Egypt and Saudi Arabia. >800 students aged 18 and 35 years (M = 20.65, SD = 1.48) completed a multidimensional internet addiction instrument. The instrument measures traits such as Withdrawal and Social Problems, Time Management and Performance and Reality Substitute. RESULTS: Analyses revealed that males scored higher than females and Saudis higher than Egyptians on nearly all scales, including the total score. Factor analysis of the 20-item instrument revealed three factors, all exhibiting sex and culture differences. CONCLUSIONS: These findings add to the body of evidence that males are higher than females in problematic internet use, as they are in addictive behaviors in general. Our findings may also imply that restrictions on male-female interaction, which are more pronounced in Saudi Arabia, may elevate the prevalence of internet addiction. The internet is also easier and cheaper to access in Saudi Arabia than in Egypt.

A modified angled plate for fixation of proximal femoral varus osteotomy in neuromuscular hip dislocation: Mechanical and clinical study.

INTRODUCTION: Proximal femoral osteotomy is an important step in the management of paralytic hip dislocation. Fixation by the angled plate is demanding and carries the risk of many complications. In this study, we made certain modifications for the angled plate. Does this plate provide a stable fixation for proximal femoral varus osteotomy? The main objective of this study was to assess the results of the modified plate in fixation of proximal femoral varus osteotomy in patients with neuromuscular hip dislocation. HYPOTHESIS: This new system would offer significant advantages over the existing systems in terms of easy application and stable fixation. MATERIAL AND METHODS: Twenty patients with paralytic hip dislocation were included in this study. The ages ranged from 5 to 15 years with a mean of 8.88±2.92 years. There were 12 boys and 8 girls. Seventeen patients had cerebral palsy and 3 had meningocele disease. Preoperative radiographs were done, and the migration percentage (MP), acetabular index (AI), and neck-shaft angle (NSA) were measured. All patients were treated with open reduction, pelvic osteotomy, and proximal femoral varus osteotomy. The femoral osteotomy was fixed by the modified angled plate in all cases. RESULTS: The osteotomy sites united in all patients and the mean time of union was 2.9±0.65 months. The acetabular index, migration percentage, and neck-shaft angle were reduced postoperatively. This reduction was statistically significant. The hips remained stable throughout the period of follow-up in all patients. No cases were complicated by non-union or implant failure. CONCLUSION: The modified angled plate (canulated interlocking blade Plate 90°) is a good method for the fixation of proximal femoral varus osteotomy in the management of neuromuscular hip dislocation. It provides a stable fixation. LEVEL OF EVIDENCE: IV; case series.

Anatase-cellulose acetate for reinforced desalination membrane with antibacterial properties.

This study aimed to prepare antifouling and highly mechanical strengthening membranes for brackish and underground water desalination. It was designed from cellulose acetate (CA) loaded anatase. Anatase was prepared from tetra-iso-propylorthotitanate and carboxymethyl cellulose. Different concentrations of anatase (0.2, 0.3, 0.5, 0.6, 0.7, and 0.8)% were loaded onto CA during the inversion phase preparation of the membranes. The prepared membranes were characterized using Fourier Transform Infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM & EDX), mechanical properties, swelling ratio, porosity determination, and ion release. The analysis confirmed the formation of anatase on the surface and inside the macro-voids of the membrane. Furthermore, anatase loading improved the CA membrane's mechanical properties and decreased its swelling and porosity rate. Also, CA-loaded anatase membranes displayed a significant antibacterial potential against Gram-positive and Gram-negative bacteria. The results showed that the salt rejection of the CA/anatase films as-prepared varies considerably with the addition of nanomaterial, rising from 46%:92% with the prepared membranes under the 10-bar operation condition and 5 g/L NaCl input concentration. It can be concluded that the prepared CA-loaded anatase membranes have high mechanical properties that are safe, economical, available, and can stop membrane biofouling.

Relationship between greenfield investment and economic growth: Evidence from Bangladesh.

The key purpose of the study is to investigate the relationship between Greenfield investment and economic growth of Bangladesh using annual time series data during the period 2003-2020. The study employs Toda-Yamamoto (T-Y) tests of Granger causality method that performs Modified Wald Test (MWALD) in order to establish causal relation among different variables. There are three steps in implementing the T-Y procedure. The first step involves using different tests (ADF, PP, and KPSS test) to identify the maximum order of integration of the variable. The second step requires selecting the optimal lag length (p) based on several lag length selection criteria. In the third step, MWALD approach is used for testing the vector auto regression model for causality. The results of the tests (ADF, PP, and KPSS) concluded that the maximum order of integration of the variables is two. Then, the optimal lag length of two (p = 2) has been selected based on several lag length selection criteria. Finally, the findings reveal the evidence of unidirectional causality from Real Greenfield Foreign Direct Investment (RGFDI) to Real Gross Domestic Product (RGDP). The key contribution of this study is to investigate the Greenfield investments-growth relationship for a country like Bangladesh.

Performance assessment and multiobjective optimization of a biomass waste-fired gasification combined cycle for emission reduction.

The use of renewable fuels leads to reduction in the use of fossil fuels and environmental pollutants. In this study, the design and analysis of a CCPP based on the use of syngas produced from biomass is discussed. The studied system includes a gasifier system to produce syngas, an external combustion gas turbine and a steam cycle to recover waste heat from combustion gases. Design variables include syngas temperature, syngas moisture content, CPR, TIT, HRSG operating pressure, and PPTD. The effect of design variables on performance components such as power generation, exergy efficiency and total cost rate of the system is investigated. Also, through multi-objective optimization, the optimal design of the system is done. Finally, it is observed that at the final decisioned optimal point, the produced power is 13.4 MW, the exergy efficiency is 17.2%, and the TCR is 118.8 $/h.

Comprehensive evaluation of zeolite/marine alga nanocomposite in the removal of waste dye from industrial wastewater.

A systematic study integrating laboratory, analytical, and case study field trial was conducted to figure out the effective adsorbent that could be used for the removal of Congo red (CR) dye from industrial wastewater effluent. The ability of the zeolite (Z) to adsorb CR dye from aqueous solutions was evaluated after it was modified by the Cystoseira compressa algae (CC) (Egyptian marine algae). Zeolite, CC algae were combined together in order to form the new composite zeolite/algae composite (ZCC) using wet impregnation technique and then characterized by the aid of different techniques. A noticeable enhancement in the adsorption capacity of newly synthesized ZCC was observed if compared to Z and CC, particularly at low CR concentrations. The batch style experiment was selected to figure out the impact of various experimental conditions on the adsorption behavior of different adsorbents. Moreover, isotherms and kinetics were estimated. According to the experimental results, the newly synthesized ZCC composite might be applied optimistically as an adsorbent for eliminating anionic dye molecules from industrial wastewater at low dye concentration. The dye adsorption on Z and ZCC followed the Langmuir isotherm, while that of CC followed the Freundlich isotherm. The dye adsorption kinetics on ZCC, CC, and Z were agreed with Elovich, intra-particle, and pseudo-second-order kinetic models, correspondingly. Adsorption mechanisms were also assessed using Weber's intraparticle diffusion model. Finally, field tests showed that the newly synthesized sorbent has a 98.5% efficient in eliminating dyes from industrial wastewater, authorizing the foundation for a recent eco-friendly adsorbent that facilitate industrial wastewater reuse.

Evaluation of serum levels of Irisin as a marker of endothelial dysfunction in patients with type 2 diabetes mellitus.

INTRODUCTION: Insulin resistance and obesity have been associated with irisin, a protein in fat cells. The levels of irisin in patients with type 2 diabetes mellitus (T2DM) were significantly lower than those in non-diabetics. This study aimed to examine the relationship between serum irisin levels and endothelial dysfunction in patients with T2DM. METHODS: There were 90 participants in this study. We matched 65 patients with T2DM with 25 healthy control participants. A series of tests were performed on the participants, including fasting blood glucose, 2 hours postprandial blood glucose, glycated haemoglobin, triglycerides (TG), total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), TG/HDL-C ratio and albumin/creatinine ratio. In addition to measuring high-sensitivity C-reactive protein (hs-CRP). Enzyme-linked immunosorbent assay (ELISA) technique was used for estimating irisin concentrations. RESULTS: Flow-mediated dilation (FMD) was significantly lower in patients with T2DM; however, there was a non-statistically significant difference between healthy controls and patients with T2DM regarding serum Irisin level. CRP and LDL levels were inversely correlated with circulating irisin levels. In a stepwise regression analysis, only the hs-CRP and LDL were statistically significant in predicting irisin level. CONCLUSIONS: In patients with T2DM, serum levels of irisin were inversely correlated with hyperglycaemia, body mass index and per cent body fat; this suggests that detecting irisin levels early can prevent cardiovascular diseases from progressing. According to the study results, serum irisin serves as a predictive marker for early cardiovascular disease, thus preventing the disease from progressing. There is a need for further research in order to understand how irisin contributes to the development of atherosclerosis and the development of diabetic complications.
