Cardiac Endothelial Impairment in the Danio Rerio Due to Change in the Circadian Rhythm
Light is one of the environmental factors which regulates the circadian rhythm in humans and animals. Circadian rhythm is a light and dark cycle which controls awakeness and sleepiness. Circadian rhythm regulates all the physiological functions. Artificial light at night disrupts the circadian rhythm in the population. Mostly developing and developed country population is very much prone to the disturbance in the circadian rhythm as shift work becomes very common. In this study we have disturbed the circadian rhythm of the Danio rerio by continuously exposing them to bright light and disturbing their resting period by creating surface waves for 96 h. At regular intervals, triplicates were meticulously extracted from control and experimental tanks, their hearts tenderly dissected and preserved in formaldehyde for subsequent analysis. Through the lens of a microtome, the intricate architecture of cardiac tissue unveiled a disquieting narrative, after 48 h and 72 h show trabeculae and necrosis in the inner layer of the ventricles and lumens were seen in the bulbus arteriosus. These findings not only mirror the cardiac consequences observed in humans experiencing circadian disruptions but also underscore the potential of zebrafish as valuable models for investigating pharmacological interventions aimed at mitigating such cardiovascular consequences.

Carcinogens in Food: Evaluating the Presence of Cadmium, Lead, in Poultry Meat in South India
Objective: Local chickens were spontaneously sampled and slaughtered in the central markets of Coimbatore, Erode, and Namakkal districts, South India. Materials and Methods: Wet digestion was used to extract lead (Pb), cadmium (Cd), and zinc (Zn) in their blood and selected different organs (intestine, breast, liver, and gizzard), and their concentrations were measured using an atomic absorption spectrophotometer. Results: Apart from the blood of chickens from Coimbatore and Namakkal, where Pb was not found, the concentrations of Pb in the blood and organs of chickens from the three towns ranged from 1.8 to 8.33 mg/kg, exceeding the maximum tolerance thresholds (0.1 mg/kg) in internal organs of poultry birds. Except for the intestine of chickens from the three areas, Cd was only found in the heart, blood, and gizzard of Erode chickens, as well as the liver and gizzard of Namakkal chickens, in concentrations ranging from 0.13 to 0.58. According to threshold level, the upper limit met the maximum limits (0.5 mg/kg). Zn was found in all sections of chickens from the three selected districts, with concentrations ranging from 4.96 to 174.17 mg/kg. Conclusion: Its concentrations were within the permissible limits (10-50 mg/kg) in some areas of certain chickens, but it surpassed the permissible limit in the liver of chicken from Coimbatore. Any organs and blood from local chickens sold in Coimbatore, Erode, and Namakkal areas can be hazardous to ones health.

Carboxymethyl Cellulose-Modified Strontium Oxide Nanoparticles: a Multifunctional Nanoplatform for C6 Glioma Therapy and Antimicrobial Applications
Glioma, a very aggressive brain tumor, poses major therapeutic challenges. The present research investigates the synthesis, characterization, and bioevaluation of carboxymethyl cellulose (CMC)-functionalized strontium oxide (SrO) nanoparticles (SrCMC) as anticancer and biocompatibility probes. SrO nanoparticles were synthesized using co-precipitation and functionalized with CMC for better dispersion and stability. Characterization by XRD, FTIR, UVVis, PL, SEM, TEM, and EDAX proved structural and optical enhancements. SrCMC showed enhanced photoluminescence with a blue shift and increased emission intensity, indicating modified surface defects. UVVis analysis revealed a slight band gap increase from 4.07eV to 4.12eV due to CMC capping. FTIR and EDAX confirmed successful functionalization, while XRD showed reduced crystallite size (32nm to 26nm) and maintained tetragonal structure. SEM and HRTEM revealed improved dispersion and decreased lattice spacing in SrCMC, reflecting surface stabilization by CMC. For in vitro tests on C6 glioma cells, the cytotoxicity was found to be time- and dose-dependent with IC?? values of 22.1, 17.6, and 14.8g/mL for SrO and 20.3, 15.8, and 12.6g/mL for SrCMC after 24, 48, and 72h respectively. In vivo biocompatibility was assessed using zebrafish embryos exposed to SrCMC nanoparticles at 0.5mg/mL and 1mg/mL across various time intervals. The agar well diffusion method was employed to assess the antimicrobial activity against the following pathogens including Gram-positive (S. pneumoniae, B. subtilis), Gram-negative (K. pneumoniae, S. dysenteriae), and fungal (C. albicans) strains. The results revealed SrCMC exhibited significant inhibitory effects against all tested organisms and comparable to streptomycin. This work shows SrCMCs potential for biomedical applications, subject to careful control of toxicity.

Carboplatin-loaded zeolitic imidazolate framework-8: Induction of antiproliferative activity and apoptosis in breast cancer cell
The challenge with breast cancer is its ongoing high prevalence and difficulties in early detection and access to effective care. A solution lies in creating tailored metalorganic frameworks to encapsulate anticancer drugs, enabling precise and targeted treatment with less adverse effects and improved effectiveness. Zeolitic imidazolate framework-8 (ZIF-8) and carboplatin (CP)-loaded ZIF-8 were synthesized and characterized using various analytical techniques. High Resolution-transmission electron microscopy of ZIF-8 and CP@ZIF-8 indicates that the particles had a spherical shape and were nanosized. The drug release rate of CP is 98% under an acidic medium (pH 5.5) because of the dissolution of ZIF-8 into its coordinating ions, whereas 35% in a physiological medium (pH 7.4) with the addition of CP, the high porosity, and pore diameter of ZIF-8 decrease from 1243 to 1041m2/g. Breast cancer MCF-7 cells were shown greater IC50 in CP@ZIF-8 (15.013.03g/mL) than free CP (34.984.25g/mL) in an in vitro cytotoxicity assessment. The cytotoxicity of the CP@ZIF-8 against MCF-7 cells was studied using the methylthiazolyldiphenyl-tetrazolium bromide method. The morphological changes were examined using fluorescent staining (acridine orangeethidium bromide and Hoechst 33258) methods. The comet assay assessed the DNA fragmentation (single-cell gel electrophoresis). The results from the study revealed that CP@ZIF-8 can be used in the treatment of breast cancer. 2024 International Union of Biochemistry and Molecular Biology, Inc. -

Carbonized Molybdenum Disulfide-Decorated Carbon from Waste Papaya Straws as Counter Electrode for Bifacial Dye-Sensitized Solar Cells
Abstract: Ongoing research efforts are aimed at developing bifacial dye-sensitized solar cells (DSSCs) that are both economically viable and high-performance. In this investigation, molybdenum disulfide-decorated biomass-derived carbon from waste papaya straws (MoS2@PS) was synthesized via a hydrothermal technique, and then subsequently subjected to annealing at various temperatures, referred to as PS26, PS27, and PS28. Annealing MoS2 -decorated PS resulted in an increase in surface area which was confirmed using BrunauerEmmettTeller measurements, revealing type IV isotherms with an H3 hysteresis loop showing the mesoscopic nature of PS28. The maximum recorded photovoltaic conversion efficiency was approximately 6.85% for the PS28 composite counter electrode (CE), highlighting its potential as a platinum-free alternative. Moreover, cyclic voltammetry and Tafel polarization studies confirmed the superior electrocatalytic activity of the MoS2@PS CE in the reduction process of triiodide ions (I3?). Studies on transmittance were conducted to validate the bifacial characteristics of DSSCs. The results from electrochemical impedance spectroscopy indicate that the MoS2@PS CE-based DSSCs exhibit rapid charge transfer at the electrode/electrolyte interface, with a resistance of RCT = 24.27 ? for the PS28 counter electrode. The favourable attributes of optimal conversion efficiency, high transmittance, ease of preparation, rapid charge transfer, and affordability suggest that MoS2@PS counter electrodes hold significant potential for applications in DSSCs.

Carbon Footprint Minimization in 5G Networks Using Blockchain Integrated Renewable Energy Management Framework
The rapid growth of 5G networks has created a huge upsurge in energy consumption, raising severe issues regarding carbon emissions and sustainability. Although current strategies like energy-efficient routing, smart grid optimization, and renewable energy integration have tried to counter these impacts, they suffer from a lack of real-time optimization and decentralized control, leading to inefficient carbon reduction and unacceptable energy cost efficiency. In order to fill these gaps, this study presents a novel framework known as BAREO-LP (Blockchain-Assisted Renewable Energy Optimization using Linear Programming) which incorporates blockchain-based peer-to-peer energy trading, renewable energy (solar and battery) modeling, and an emission-conscious linear programming optimization framework. The developed model is utilized through the Python programming language and evaluated on the publicly available 5G-Energy Consumption Dataset from Kaggle. Experimental outcomes show a 58% decrease in carbon emissions and a 32% cost reduction against conventional grid-based and smart grid scenarios. The method also gains an accuracy gain of 16% in energy demand forecasting with minimized load balancing and resource optimization. The blockchain module provides trust and transparency in peer-to-peer energy trading, making the model scalable and realizable in real-world 5G implementations. This multi-faceted strategy sets a new standard for green communication infrastructures and calls for further investigation in sustainable 5G network planning. 2025 IEEE. -
Carbon dots-Zno/TiO2 ternary nanocomposite as a proficient material to enhance the performance of natural DSSC
A novel sustainable approach for enhancing the efficiency of dye-sensitized solar cells (DSSCs) involves the utilization of a combination of ZnO and carbon dots (CDs) derived from Citrus medica fruit extract, along with microwave-synthesized TiO2 nanoparticles for the preparation of the photoanode. Natural dyes such as Hibiscus rosa-sinensis and Allium Cepa peel are employed as sensitizers to reduce production costs. This co-activation method has demonstrated a significant improvement in the output parameters of the devices. Notably, the photoanode co-activated with ZnO-CD composite (ZnO-CD/TiO2) exhibits the most favorable output parameters when combined with Hibiscus rosa-sinensis dye (open circuit voltage (Voc) = 0.80 V, short circuit current density (Jsc) = 6.62 mA/cm2, fill factor (FF) = 64.20 %, photo conversion efficiency (PCE) = 3.40 %) and Allium Cepa peel dye (Voc = 0.81 V, Jsc = 6.79 mA/cm2, FF = 65.70 %, PCE = 3.61 %). When paired with Allium Cepa dye, the CD modified photoanode (CD/TiO2) offers Voc = 0.73 V, Jsc = 6.64 mA/cm2, FF = 61.27 % and PCE = 2.97 %. Similarly, when combined with Hibiscus rosa-sinensis dye, the output parameters of the CD/TiO2 photoanode are Voc = 0.72 V, Jsc = 6.54 mA/cm2, FF = 64.4 % and PCE = 3.03 %. In comparison to all tested devices, the unmodified photoanode (TiO2) displayed the lowest performance, with parameters such as Voc = 0.59 V, Jsc = 6.45 mA/cm2, FF = 52.5 %, PCE = 2.10 % using Allium Cepa peel dye, and Voc = 0.66 V, Jsc = 6 mA/cm2, FF = 51.60 %, PCE = 2.04 % using Hibiscus rosa-sinensis dye. Furthermore, the co-activation process has been shown to enhance the stability of the devices. While the unmodified photoanodes ceased to operate after eight days, the ZnO-CD composite co-activated photoanodes retained their initial efficiencies up to 61.50 % and 68.53 % with the Allium Cepa peel dye and Hibiscus rosa-sinensis dye, respectively. Therefore, this study underscores the potential of the synthesized composite material in enhancing the performance of natural DSSCs. 2024 Elsevier Ltd -

Carbon dots derived from frankincense soot for ratiometric and colorimetric detection of lead (II)
We report a simple one-pot hydrothermal synthesis of carbon dots from frankincense soot. Carbon dots prepared from frankincense (FI-CDs) have narrow size distribution with an average size of 1.80 nm. FI-CDs emit intense blue fluorescence without additional surface functionalization or modification. A negative surface charge was observed for FI-CDs, indicating the abundance of epoxy, carboxylic acid, and hydroxyl functionalities that accounts for their stability. A theoretical investigation of the FI-CDs attached to oxygen-rich functional groups is incorporated in this study. The characteristics of FI-CDs signify arm-chair orientation, which is confirmed by comparing the indirect bandgap of FI-CDs with the bandgap obtained from Tauc plots. Also, we demonstrate that the FI-CDs are promising fluoroprobes for the ratiometric detection of Pb2+ ions (detection limit of 0.12 ?M). The addition of Pb2+ to FI-CD solution quenched the fluorescence intensity, which is observable under illumination by UV light LED chips. We demonstrate a smartphone-assisted quantification of the fluorescence intensity change providing an efficient strategy for the colorimetric sensing of Pb2+ in real-life samples. 2022 IOP Publishing Ltd. -
