RESUMO

Transition metal (TM) ion doping in II-VI semiconductors can produce exciton magnetic polarons (EMPs) and localized EMPs containing longitudinal optical (LO) phonon coupling, which will be discussed in this paper. TM ion doping in II-VI semiconductors for a dilute magnetic semiconductor show emission via magnetic polarons (MPs) together with hot carrier effects that need to be understood via its optical properties. The high excitation power that is responsible for hot carrier effects suppresses the charge trapping effect in low exciton binding energy (8.12 meV) semiconductors, even at room temperature (RT). The large polaron radius exhibits strong interaction between the carrier and MP, resulting in anharmonicity effects, in which the side-band energy overtone to LO phonons. The photon-like polaritons exhibit polarized spin interactions with LO phonons that show strong spin-phonon polaritons at RT. The temperature-dependent photoluminescence spectra of Ni-doped ZnTe show free excitons (FX) and FXs interacting with 2LO phonon-spin interactions, corresponding to3T1(3F) →1T1(1G) and EMP peaks with ferromagnetically coupled Ni ions at3T1(3F) →1E(1G). In addition, other d-d transitions of single Ni ions (600-900 nm) appear at the low-energy side. RT energy shifts of 14-38 meV are observed due to localized states with density-of-states tails extending far into the bandgap-related spin-induced localization at the valence band. These results show spin-spin magnetic coupling and spin-phonon interactions at RT that open up a more realistic new horizon of optically controlled dilute magnetic semiconductor applications.

RESUMO

The solid waste management (SWM) system is in a transitional phase in developing economies, and local municipalities and waste management companies are stepping toward integrating a waste treatment approach in the scheme of waste handling. However, there is an urgent need to explore cost-effective techniques, models, and potential revenue streams to sustain the state-run waste sector self-sufficiently. The proposed SWM model aims to support the local waste sector in Islamabad, the capital city of Pakistan, with 100% service area coverage to attain environmental and economic sustainability by defining dedicated waste collection streams to ensure quality material recovery under a cost-effective approach and modality. The innovative approach is applied to allocate the tonnage to various streams as per the city's current land use plan. The estimated/cost of the cleanliness services will be USD13.1 million per annum with an estimated per ton cost of USD 23. The establishment of the proposed material recovery facility (MRF) will process about 500 t/d of waste to produce 45 t/d compost and recover 130 t/d of recyclables. The environmentally friendly model saves 2.4 million tons of CO2‒eq/month from composting and recycling. The average economic potential from MRF and debris-crushing plants, including environmental benefit value, is calculated as USD 3.97 million annually. Recovery of services fee (70%) for various collection streams based on city land use and socio-economic conditions will generate revenue of USD 7.33 million annually. The total revenue will be USD 11.31 million (86% of total annual expenditures) to track the sector's self-sufficiency. To successfully reach the Sustainable Development Goals (SDGs) and Nationally Determined Contributions (NDCs), engaging the private sector from environmentally advanced economies to collaborate in the waste sector to enhance local technical capabilities is recommended.

RESUMO

The aim of this study was to investigate the effectiveness of continuous cold flow and compression device as against traditional icing regimen and without icing after anterior cruciate ligament (ACL) reconstruction. All patients undergoing ACL reconstruction from June 2021 to August 2021 were enrolled in this study. Patients were randomly allocated to three groups: A control group (n=10) with no ice regimen post-operatively, a second control group (n=10) with ice bag, and a third group (n=10) with continuous cold flow and compression device (physiolab). All patients who had isolated ACL tear evident on magnetic resonance imaging were included. Pain intensity, limb girth, Oxford Knee Score, and 12-item survey form were measured pre- and post-operatively. Significant difference was noted between pain scores in all groups at two- and six-week follow-ups with p-value of 0.004 and 0.01. The test for "between subject effects" showed significant difference (p=0.007) in limb girth between the two groups. Cold and compression device can be used to reduce swelling immediately after ACL reconstruction.

RESUMO

Radial neck fractures with radial head rotation are very rare and extremely difficult to manage. We present the case of an 11-year-old girl who fell on her outstretched left upper extremity and damaged her left elbow in a road traffic accident. An arthrotomy was performed under a C-Arm fluoroscope, which confirmed the radial head displacement of 180° along with the fracture. The fracture site was reduced and fixed with two Kirschner wires, cutting the wire short at its distal end for a complete closure. Open reduction and internal fixation were followed by casting for five weeks. After two years of follow-up, she had complete pain free range of motion of the affected limb. No post-operative complications have been observed till date. Open reduction and internal fixation with two Kwires is a viable option for such complex injuries. However, further evaluation of outcomes and post-operative complications are required.

RESUMO

The use of chemical preservatives in the baking industry is a common practice to extend the shelf life of baked goods However, there is growing interest in natural alternatives due to worries about the security and potential health risks of these chemicals. The purpose of this concurrent review is to investigate the potential of using essential oils and bio-preservatives in place of chemical preservatives in the baking industry. With a focus on their efficiency in extending the shelf life of baked goods, the review includes a thorough analysis of the most recent research on the use of bio-preservatives and essential oils in food preservation. The findings suggest that bio-preservatives and essential oils can be effective in preserving baked goods and may offer a safer and more natural alternative to chemical preservatives. However, further research is needed to fully understand the potential of these natural alternatives and to optimize their use in the baking industry.

RESUMO

The performance of the Graphene/Si (Gr/Si) Schottky interface and its potential in future electronics strongly rely on the quality of interconnecting contacts with external circuitry. In this work, we investigate the dominating and limiting factors of Gr/Si interfaces designed for high light absorption, paying particular attention to the nature of the contact failure under high electrostatic discharge (ESD) conditions. Our findings indicate that severe current crowding at contact edges of the graphene is the dominating factor for the device breakdown. Material degradation and electrical breakdown are systematically analyzed by atomic force, Raman, scanning electron, and energy-dispersive x-ray spectroscopies. This work enlists the robustness and limitations of Gr/Si junction in photodiode architecture under high ESD conditions that can be used as general guidelines for 2D-3D electronic and optoelectronic devices.

RESUMO

Infections in critically-ill patients caused by extensively-drug-resistant (XDR)-Pseudomonas aeruginosa are challenging to manage due to paucity of effective treatment options. Cefepime/zidebactam, which is currently in global Phase 3 clinical development (Clinical Trials Identifier: NCT04979806, registered on July 28, 2021) is a novel mechanism of action based ß-lactam/ ß-lactam-enhancer combination with a promising activity against a broad-range of Gram-negative pathogens including XDR P. aeruginosa. We present a case report of an intra-abdominal infection-induced sepsis patient infected with XDR P. aeruginosa and successfully treated with cefepime/zidebactam under compassionate use. The 50 year old female patient with past-history of bariatric surgery and recent elective abdominoplasty and liposuction developed secondary pneumonia and failed a prolonged course of polymyxins. The organism repeatedly isolated from the patient was a New-Delhi metallo ß-lactamase-producing XDR P. aeruginosa resistant to ceftazidime/avibactam, imipenem/relebactam and ceftolozane/tazobactam, susceptible only to cefepime/zidebactam. As polymyxins failed to rescue the patient, cefepime/zidebactam was administered under compassionate grounds leading to discharge of patient in stable condition. The present case highlights the prevailing precarious scenario of antimicrobial resistance and the need for novel antibiotics to tackle infections caused by XDR phenotype pathogens.

RESUMO

Wireless connectivity delay, disruption, or failure can significantly affect the performance of wireless-enabled medical devices, which in turn causes potential risks to the patient. Notably, the challenges related to connectivity provisioning are exacerbated in the fifth-generation (5G)-enabled healthcare use cases where mobility is utilized. In this article, we describe relevant 5G-enabled healthcare use cases involving mobility and identify the connectivity challenges that they face. We then illustrate practical implementation considerations, tradeoffs, and future research directions for enabling reliable 5G healthcare transmissions. This is done through simulation of connected ambulances as an example use-case.

RESUMO

Urinary tract infection is an infectious disease that requires immediate treatment. It can occur in any age group and involves both genders equally. The present study was to check the resistance of some antibiotics and to assess the antibacterial potential of three extracts of three plants against notorious bacteria involved in urinary tract infections. Along with assessing the antibacterial activity of plant extracts, we checked for the anticancer potential of these extracts against the cancer cell lines MCF-7 and A2780. Cancer is the leading cause of mortality in developed countries. Determinations of total flavonoid content, total phenolic content, total alkaloid content, total tannin content, total carotenoid content, and total steroid content were performed. The disk diffusion method was used to analyze the antibacterial activity of plant extracts. Ethanolic extract of Selenicereus undatus showed sensitivity (25-28 mm) against bacteria, whereas chloroform and hexane extracts showed resistance against all bacteria except Staphylococcus (25 mm). Ethanolic extract of Pistacia vera L. showed sensitivity (22-25 mm) against bacteria, whereas chloroform and hexane extracts showed resistance. Ethanolic extract of Olea europaea L. showed sensitivity (8-16 mm) against all bacteria except Staphylococcus, whereas chloroform and hexane extracts showed resistance. Positive controls showed variable zones of inhibition (2-60 mm), and negative control showed 0-1 mm. The antibiotic resistance was much more prominent in the case of hexane and chloroform extracts of all plants, whereas ethanolic extract showed a sensitivity of bacteria against extracts. Both cell lines, MCF-7 and A2780, displayed decreased live cells when treated with plant extracts.

RESUMO

Recent advances in quantitative proteomics show that WD40 proteins play a pivotal role in numerous cellular networks. Yet, they have been fairly unexplored and their physical associations with other proteins are ambiguous. A quantitative understanding of these interactions has wide-ranging significance. WD40 repeat protein 5 (WDR5) interacts with all members of human SET1/MLL methyltransferases, which regulate methylation of the histone 3 lysine 4 (H3K4). Here, using real-time binding measurements in a high-throughput setting, we identified the kinetic fingerprint of transient associations between WDR5 and 14-residue WDR5 interaction (Win) motif peptides of each SET1 protein (SET1Win). Our results reveal that the high-affinity WDR5-SET1Win interactions feature slow association kinetics. This finding is likely due to the requirement of SET1Win to insert into the narrow WDR5 cavity, also named the Win binding site. Furthermore, our explorations indicate fairly slow dissociation kinetics. This conclusion is in accordance with the primary role of WDR5 in maintaining the functional integrity of a large multisubunit complex, which regulates the histone methylation. Because the Win binding site is considered a key therapeutic target, the immediate outcomes of this study could form the basis for accelerated developments in medical biotechnology.

RESUMO

5G and Beyond 5G (B5G) communication networks, with their characteristics of increasing speed, connectivity, reliability, availability and capacity while reducing latency, have the potential to transform the healthcare sector by opening possibilities for novel healthcare use cases and applications. Service level agreements (SLAs) can help enable these new healthcare use cases by documenting the communication requirements, performance standards, and roles and responsibilities of the stakeholders involved in providing safe and effective 5G-enabled healthcare to patients. However, the peculiarities and nuances of 5G implementations give rise to gaps in this area that should be addressed to streamline the implementation of 5G technology in healthcare. This magazine article highlights the key challenges and describes open research questions related to SLAs for 5G-healthcare systems. Addressing the research challenges in this space will help in developing robust SLAs that can ensure that device manufacturers, network service providers, users, and regulatory authorities share a common framework to safely integrate 5G & B5G technology in healthcare.

RESUMO

Benzimidazole ring system is an important pharmacophore with diverse pharmacological activities. In this study, we explored the anti-arthritic effects of newly synthesized acetamide derivatives of 2-aminobenzimidazole (N1 and N2) in rats. FTIR and NMR spectroscopies were used to characterize these compounds. Carrageenan (CRG) induced paw edema model was used to test the acute anti-inflammatory activity of various doses (10, 20 and 30 mg/kg) of N1 and N2 compounds. Based on acute anti-inflammatory effects, the most potent dose of each compound was selected and investigated in complete freund's adjuvant (CFA) induced inflammatory arthritis (RA) model (n = 4 in each group). Histopathological, hematological, radiographic, and RT-qPCR analyses were performed to assess the progression or resolution of inflammatory arthritis. The tested compounds produced a dose-dependent anti-inflammatory activity against CRG induced paw inflammation and similarly reduced edema in CFA induced inflammatory arthritis model. Histopathological and X-ray analyses of ankle joints revealed minimal inflammation and normal joint structures in N1 and N2 treated groups. The tested compounds also reduced the levels of autoantibodies and restored hematological parameters. Interestingly, the tested compounds did not elevate aspartate aminotransferase and alanine transaminase levels and displayed a better safety profile than methotrexate. N1 and N2 compounds also attenuated the transcript levels of IRAK1, NF-kB1, TNF-α, IL-1ß, IL17 and MMP1. In addition, N1 displayed a greater inhibition of mRNA levels of COX1, COX2, mPGES1 and PTGDS as compared to N2. Our findings demonstrate that N1 and N2 compounds possess strong anti-arthritic activity which can be attributed to the suppression of pro-inflammatory mediators.

RESUMO

This retrospective case series analyses the clinical and radiological outcomes of displaced proximal humerus fractures treated with PHILOS plate system and iliac crest bone autograft. Twenty-six patients with displaced fractures of proximal humerus, who were treated with PHILOS plate and autologous iliac crest bone grafts from January 2015 to September 2020, were included in this study. The inclusion criteria were proximal humerus fractures with displacement of more than 1cm and angulation of more than 45 degrees. The functional outcomes were evaluated using DASH and constant score. Radiological outcomes were measured by calculating the fracture union. The average age of the cohort was 47.28±13.69 years. Over all, the mean DASH score was 10.25 and constant score was 77.65 at three-year follow-up. The PHILOS plate with iliac crest bone autologous graft provides good radiological and functional outcomes, especially for the cases with bone defects and poor-bone stock.

RESUMO

The main objective of the current research was to explore the physicochemical, microbial and sensorial attributes of cereals bran cell wall (CBCW) enriched bread. In 1st phase, the cell wall wasextracted from different cerealsbran and characterized for its dietary fiber profile and antioxidant activity. In addition, bread was prepared with the additionof CBCW at different ratios and explored for physicochemical, microbialand sensorial characteristics. Current results showed that total dietary fiber contents of CBCW were 59.1 ± 0.2%, 61.2 ± 0.03% and 68.8 ± 0.2% in wheat, maize and oat bran respectively. Furthermore, maize bran cell wall showed higher antioxidant activityof ferric reducing antioxidant power (FRAP), DPPH and ABTS were 52.5 ± 0.12, 28.4 ± 0.07 and 18 ± 0.05 µmol TE/g as compared to wheat and oat bran cell wall. Additionally, CBCWimproved the bread quality in terms of physicochemical, microbial and sensorial characteristics.Moreover, CBCW-enriched bread showed higher loaf volume, loaf height, the specific volume of loaf and weight of bread as compared to control due to less baking loss. Furthermore, maize bran cell wall enriched bread exhibited less growth after 4 days as compared to other treatments. Moreover, CBCW-enriched bread showed higher sensorial properties score than C0.Convulsively, CBCW-enriched bread has good physicochemical, microbial and sensorial properties as compared to control bread.

RESUMO

In the current study, the probiotic (Lactobacillus acidophilus) was encapsulated using Gum Arabic and polyvinyl alcohol blended nanofibers by electrospinning. Obtained nanofibers were characterized in terms of particle size, diameter, mechanical strength, and encapsulation efficiency. The molecular and internal structure characterization was carried out using Fourier transform infrared spectroscopy and X-ray diffraction respectively. Thermo Gravimetric (TGA) analysis was conducted to determine the thermal features of PVA/GA/probiotics nanofibers. Free and encapsulated probiotics were also subjected to in vitro assay under different detrimental conditions. Images obtained using SEM indicated that probiotics were successfully encapsulated in blends by a nano-spider. FTIR and XRD spectra showed bonding interactions between the wall and core materials. In-vitro assay indicated that probiotics with encapsulated showed significantly (P < 0.05) viability compared to free cells. Free cells lost their viability under simulated gastrointestinal conditions while encapsulated cells retained viability count above the therapeutic number (107 cfu).

RESUMO

Chicory can be used as herbal medicine against different ailments and also added to daily diet as vegetable or animal feed. An efficacy trial was conducted to assess the potential of this plant against liver disorders using rodent modeling. The trials comprised two modules i.e., normal diet and chicory-based supplemented diet. Moreover, experimental animals (rats) were divided into six groups with both modules including C0 (control diet), C1 (Chicory root containing diet), C2 (chicory seed containing diet), C3 (chicory stem containing diet) and C4 (chicory leaf containing diet). During 56 days of the trial period, serum lipid profile, liver and renal functioning tests were performed. The highest feed and water intake, as well as weight gain, was noted in control (C0) trailed by C1, C2, C3, C4 and C5group in an experimental trial, respectively. The resultant diet C2 lowered the liver alkaline phosphatase level (ALP) from C0 (240.72±3.35) to 203.52±2.08 (C2), respectively. Similarly, C2 significantly lowered the ALT from 60.28±2.23 (C0) &57.58±0.91 (C2) in rats. Moreover, C2 treatment showed a maximum reduction of AST from 145.13±2.10 (C0) to 134.52±1.24 (C2), respectively. Convincingly, chicory-based diet may be employed as an alternative to medication in the prevention and treatment of hypercholesterolemia and hepatic malfunctioning.

RESUMO

Determination of ionization constant, commonly termed pKa is of prime interest in a wide range of pharmaceutical Research fields. The pKa of a compound is critical as it influences on its physicochemical parameters in biological and environmental systems. The study of pKa is also essential not only for the formulation of drugs and optimization of a variety of novel analytical methods, establishing new pharmaceutical dosage forms yet the exploration of the mechanism of action of drugs. In this research work, we have determined pKa values of isoniazid (INH) derivatives; N'-[(4-methyl benzoyl)] pyridine-4-carbohydrazide (I) and [2-oxo-2-(4-phenyl phenyl) ethyl] (pyridine-4-yl formamido) azanium bromide (II) through UV- spectrophotometry, a method is known for the accuracy and precision of results. These two compounds (I and II) were synthetically prepared in our lab by derivatizing INH and reported by Naeem et al in the year 2014. The mean pKa values for compounds I and II were experimentally determined as 7.37 and 3.76 respectively. The study is helpful in understanding the physicochemical behavior of these compounds in a biological system. Different pharmacokinetic parameters were also predicted using online web tools which ensured significant drug-likeness for both compounds.

RESUMO

The Current study was planned to explore the therapeutic potential of green tea, black tea and ginger based nutraceuticals (catechins, theaflavins and ginger freeze dried extract) against obesity, diabetes and renal malfunctioning. Bioevaluation study was carried out by involving 250 male Sprague Dawley rats. Accordingly, three types of studies were conducted on the basis of different diets i.e. study I (Hyperglycemic rats), study II (obese rats), study III (liver malfunctional rats) each study comprised of five groups of rats ten in each (Sample size according to power analysis) were provided the five types of drinks i.e. control, theaflavin enriched, catechins enriched, ginger extract supplemented and combination of catechins, theaflavins and ginger extract were given to the representative groups. Results showed that the body weight of rats effected significantly with functional drinks in all studies. However, catechin enriched drink (T1) resulted maximum reduction in weight during the entire study. Similarly, T2 exerted maximum decline in cholesterol level during study I, II and III by 11.03 & 10.63, 7.62 & 8.05 and 5.99 & 6.01% whereas LDL by 14.25 & 15.10, 10.45 & 12.10 and 7.25 & 8.01%, respectively (trial 1 & 2). The attenuation in serum glucose and enhancement in insulin level of rats are the indicators for the positive impact of black tea functional drinks. In this context, Catechins+theaflavins+GFD enriched drink (T4) Showed better performance than rest and caused 8.82 & 9.77, 11.03 & 12.23 and 5.83 & 5.96% reduction in glucose. Moreover, the T4 significantly improved the liver and antioxidant enzymes. Accordingly, T4 was proved effective for glutathione enhancement whilst T2 alleviated TBARS efficiently during the investigation. The normal ranges of renal function tests and hematological aspects proved the safety of resultant drinks. From the current exploration, it is concluded that drinks supplemented with theaflavin and catechins & GFD are effectual to mitigate lifestyle related malfunctioning.

RESUMO

Experiment was conducted to determine the proximate, minerals, antioxidant capacities and enzymes activities of grape fruit peel and grape fruit pomace along with sensorial evaluation of functional drinks. In this milieu, values of grapefruit peel and pomace powder for moisture, fat, crude protein, carbohydrate, crude fiber, ash, and NFE were recorded as 10.85±1.34,8.9±0.08 , 9.27±0.03, 7.69±0.02, 60.22±2.32, 50.33±2.1, 6.13±0.02, 6.13±0.01, 2.97±0.01 ,2.16±0.01 ,10.56±1.97, 24.97±2.4, respectively whilst in time intervals highest TPC for peel (118.66±8.9) mg/g was observed in 60 min followed by (102.33±7.6) mg/g at 90 min and (82.02±5.5) mg/g at 30 min respectively Whereas, the recorded TPC for pomace at 30, 60 and 90 minute were (112.73±9.1) mg/g has observed in 60 min followed by (97.21±7.9) mg/g at 90 min and (84.55±5.8) mg/g at 30 min respectively. Among the time intervals highest flavonoids contents of peel were at 60 min 52.3±1.9% followed by 52.51±1.7% at 90 min and minimum 50.72±1.4% at 30 min. The highest ABTS value was observed for peel content 248.33±5.6 λg/ml in ethanol extract followed by methanolic extract 212.11±4.4 λg/ml least in water extract 152.5±3.2 λg/ml. The means reviewed FRAP activity highest value for ethanol in peel and pomace were (92.66±5.3 µg/ml Fe2+/g) & (82.47±4.2 µg/ml Fe2+/g) followed by methanol (86.33±4.1 µg/ml Fe2+/g) & (76.83±3.4 µg/ml Fe2+/g) and least in water (66.46±2.2 µg ml Fe2+/g) &(54.24±2.1 µg/ml Fe2+/g) respectively. The color acceptability varied significant effect between 7.49 to 7.55 in T0 to T3. Likewise, storage imparted more significant decline from 7.72 to 7.30 at 0th to 60th days, respectively. The flavor scores were 7.59, 7.41, 7.26 and 7.53 in T0, T1, T2 and T3 respectively. The overall acceptability of drink was significantly increase from initiation (0th) day to termination (60th) day as 7.68 to 6.9.

RESUMO

Smart home applications are ubiquitous and have gained popularity due to the overwhelming use of Internet of Things (IoT)-based technology. The revolution in technologies has made homes more convenient, efficient, and even more secure. The need for advancement in smart home technology is necessary due to the scarcity of intelligent home applications that cater to several aspects of the home simultaneously, i.e., automation, security, safety, and reducing energy consumption using less bandwidth, computation, and cost. Our research work provides a solution to these problems by deploying a smart home automation system with the applications mentioned above over a resource-constrained Raspberry Pi (RPI) device. The RPI is used as a central controlling unit, which provides a cost-effective platform for interconnecting a variety of devices and various sensors in a home via the Internet. We propose a cost-effective integrated system for smart home based on IoT and Edge-Computing paradigm. The proposed system provides remote and automatic control to home appliances, ensuring security and safety. Additionally, the proposed solution uses the edge-computing paradigm to store sensitive data in a local cloud to preserve the customer's privacy. Moreover, visual and scalar sensor-generated data are processed and held over edge device (RPI) to reduce bandwidth, computation, and storage cost. In the comparison with state-of-the-art solutions, the proposed system is 5% faster in detecting motion, and 5 ms and 4 ms in switching relay on and off, respectively. It is also 6% more efficient than the existing solutions with respect to energy consumption.
