        Anti-Fibrotic Effects of DL-Glyceraldehyde in Hepatic Stellate Cells via Activation of ERK-JNK-Caspase-3 Signaling Axis

        Samsuzzaman Md.,Kim Sun Yeou 한국응용약물학회 2023 Biomolecules & Therapeutics(구 응용약물학회지) Vol.31 No.4

        During liver injury, hepatic stellate cells can differentiate into myofibroblast-like structures, which are more susceptible to proliferation, migration, and extracellular matrix generation, leading to liver fibrosis. Anaerobic glycolysis is associated with activated stellate cells and glyceraldehyde (GA) is an inhibitor of glucose metabolism. Therefore, this study aimed to investigate the anti-fibrotic effects of GA in human stellate LX-2 cells. In this study, we used cell viability, morphological analysis, fluorescence-activated cell sorting (FACS), western blotting, and qRT-PCR techniques to elucidate the molecular mechanism underlying the anti-fibrotic effects of GA in LX-2 cells. The results showed that GA significantly reduced cell density and inhibited cell proliferation and lactate levels in LX-2 cells but not in Hep-G2 cells. We found that GA prominently increased the activation of caspase-3/9 for apoptosis induction, and a pan-caspase inhibitor, Z-VAD-fmk, attenuated the cell death and apoptosis effects of GA, suggesting caspasedependent cell death. Moreover, GA strongly elevated reactive oxygen species (ROS) production and notably increased the phosphorylation of ERK and JNK. Interestingly, it dramatically reduced α-SMA and collagen type I protein and mRNA expression levels in LX-2 cells. Thus, inhibition of ERK and JNK activation significantly rescued GA-induced cell growth suppression and apoptosis in LX-2 cells. Collectively, the current study provides important information demonstrating the anti-fibrotic effects of GA, a glycolytic metabolite, and demonstrates the therapeutic potency of metabolic factors in liver fibrosis.

        ( Md Razob Ali ),( Samsuzzaman ),( Eliezel Habineza ),( Md Shaha Nur Kabir ),( Mohammod Ali ),( Beom-seon Kang ),( Sun-ok Chung ) 한국농업기계학회 2023 한국농업기계학회 학술발표논문집 Vol.28 No.2

        Plastic seedling pots have been widely used due to their light weight and durable nature, but they hinder root establishment efficiency. However, recent studies have demonstrated that biodegradable potted seedlings could improve seedling resilience, while also being eco-friendly through natural decomposition. In this research, a transplanting mechanism for biodegradable potted vegetable seedlings was designed using commercial software, incorporating working speed analysis to enhance smooth collection and plantation of leafy vegetable seedlings. Theoretical analysis of the vegetable transplanting mechanism for biodegradable seedling pots was conducted, including calculations of position, velocity, acceleration, and input driving torque. Additionally, the selection of appropriate link combinations within the mechanism was explored to ensure smooth transplantation of potted seedlings in optimum depths and spacings. The kinematic model of the transplanting mechanism was simulated using commercial mechanical design and simulation software. The transplanter was comprised of a 4-bar mechanism: a driving link, a driven link, a connecting link, and a supporting bar. In order to enable better hopper motion, a spring was affixed between the driven link and the ground. The movement of the mechanism was primarily controlled through a crank-rocker mechanism, where the arm lengths play a crucial role in determining the planting trajectory. The mathematical model analysis and simulation revealed that a forward speed of the transplanter of 300 mm/s and a rotating speed of the dibbling mechanism of 40 rpm were favored of 48 seedlings/min in order to obtain a high degree of seedling uprightness. The simulated velocities and accelerations of the end hopper in ‘X’ and ‘Y’ directions for suitable link combination were found to be 430mm/s,530mm/s,and 975 mm/s2,2091mm/s2,respectively.The required driving torque was observed to be 603N-mm,and the vertical linear displacement of the hopper was 281mm.

        Dey Pabel Kanti,Banu Selina,Milufarzana Milufarzana,Robin Sakib,Mazumdar Nayon Chandra,Samsuzzaman Samsuzzaman,Kabir Md Shaha Nur 사단법인 한국정밀농업학회 2024 정밀농업과학기술지 Vol.6 No.1

        Water management in irrigated agricultural fields is a critical issue in Bangladesh due to a lack of improved irrigation facilities for efficient use of irrigation water, and the cost of crop production is high with low agricultural productivity in agriculture. Therefore, this research aimed to design and implement an internet of things (IoT)-based solar-powered smart irrigation system by sensing the soil moisture levels and periodically controlling the pump operations when the soil moisture is below the required level. A sun-tracking solar system was developed to generate more electricity by tracking the orientation of the sun. A comparison was made between the energy of a fixed-panel solar system with a 24.95° tilt angle and a solar tracking system with no tilt angle. The solar tracker device utilizes a Light Dependent Resistor (LDR) sensor to track the sun, aligning the 150 W solar panel perpendicular to maximize energy capture. This energy is converted into electrical energy and stored in a 12V battery for powering the operation of the submersible pump (DC 12V, 150 W). A wireless sensor network was employed to monitor pumping status and energy comparison in a rice field. A sub-station transferred water level data wirelessly to a main station, where a microcontroller processed the data. The relay module automatically triggered pumping, and the data was stored in the cloud. The solar tracking system outperformed the fixed-panel system with a fixed tilt angle of 24.95° in terms of output power by a remarkable 26.72%. There is a huge potential for solar irrigation systems in Bangladesh, and they can provide sustainable solutions with low irrigation costs. Therefore, this IoT-based solar-powered smart irrigation system could play a vital role in improving irrigation management systems with increased water use efficiency.

        Kadhane Pravin S.,Baraskar Bharat G.,Darvade Tulshidas C.,Ramdasi Onkar A.,Samsuzzaman Md.,Kambale Rahul C. 한국세라믹학회 2022 한국세라믹학회지 Vol.59 No.5

        Three different measurement methods to determine the structural phase transitions and Curie temperature of Ba 0.97 Ca 0.03 Ti 1−x Sn x O 3 (BCTS, x = 0.025, and 0.035 mol). electroceramics are discussed. At room temperature, both com- positions reveal the tetragonal perovskite lattice symmetry as evidenced by X-ray diffraction, temperature-dependent dielectric constant and Raman active modes. The temperature-dependent dielectric study reveals T R-O at − 60 °C, T O-T at 14 °C, T T-C at 126 °C for composition x = 0.025 and T R-O at − 50 °C, T O-T at 20 °C, T T-C at 118 °C for composition x = 0.035. To evident the structural changes happening at phase transitions as well as Curie temperature the variation of polarization concerning temperature is investigated which supports the temperature-dependent dielectric and Raman spectroscopy studies. The room temperature recoverable energy storage density and efficiency of BCTS are calculated by the integral area 3 of the polarization–electric fi eld (P-E) hysteresis loop. The observed recoverable energy storage density is 21.80 mJ/cm and 32.40 mJ/cm 3 with the efficiency of 43.58% and 52.25% for composition x = 0.025 and 0.035 mol., respectively. These results are having practical importance, due to the higher recoverable energy storage density and efficiency with moderate Curie temperature compared to the pure BaTiO 3 . Thus, it can be used as a promising novel and environmentally friendly, lead-free material, for different applications in low carbon vehicles, renewable energy technologies, integrated circuits, and for the high-temperature aerospace sector.
