An efficient cardio vascular disease prediction using multi-scale weighted feature fusion-based convolutional neural network with residual gated recurrent unit
Comput Methods Biomech Biomed Engin. 2024 Apr 17:1-25. doi: 10.1080/10255842.2024.2339475. Online ahead of print.ABSTRACTThe cardiovascular disease (CVD) is the dangerous disease in the world. Most of the people around the world are affected by this dangerous CVD. In under-developed countries, the prediction of CVD remains the toughest job and it takes more time and cost. Diagnosing this illness is an intricate task that has to be performed precisely to save the life span of the human. In this research, an advanced deep model-based CVD prediction and risk analysis framework is proposed to minimize the death rate of humans ...

Electricity generation and real oily wastewater treatment by Pseudomonas citronellolis 620C in a microbial fuel cell: pyocyanin production as electron shuttle
Bioprocess Biosyst Eng. 2024 Apr 17. doi: 10.1007/s00449-024-03016-1. Online ahead of print.ABSTRACTIn the present study, the potential of Pseudomonas citronellolis 620C strain was evaluated, for the first time, to generate electricity in a standard, double chamber microbial fuel cell (MFC), with oily wastewater (OW) being the fuel at 43.625 mg/L initial chemical oxygen demand (COD). Both electrochemical and physicochemical results suggested that this P. citronellolis strain utilized efficiently the OW substrate and generated electricity in the MFC setup reaching 0.05 mW/m2 maximum power. COD removal was remarkable reachin...

Synthetic co-culture in an interconnected two-compartment bioreactor system: violacein production with recombinant E. coli strains
Bioprocess Biosyst Eng. 2024 Apr 16. doi: 10.1007/s00449-024-03008-1. Online ahead of print.ABSTRACTThe concept of modular synthetic co-cultures holds considerable potential for biomanufacturing, primarily to reduce the metabolic burden of individual strains by sharing tasks among consortium members. However, current consortia often show unilateral relationships solely, without stabilizing feedback control mechanisms, and are grown in a shared cultivation setting. Such 'one pot' approaches hardly install optimum growth and production conditions for the individual partners. Hence, novel mutualistic, self-coordinating consor...

From PDB files to protein features: a comparative analysis of PDB bind and STCRDAB datasets
AbstractUnderstanding protein structures is crucial for various bioinformatics research, including drug discovery, disease diagnosis, and evolutionary studies. Protein structure classification is a critical aspect of structural biology, where supervised machine learning algorithms classify structures based on data from databases such as Protein Data Bank (PDB). However, the challenge lies in designing numerical embeddings for protein structures without losing essential information. Although some effort has been made in the literature, researchers have not effectively and rigorously combined the structural and sequence-base...

Study on mechanical properties of dual-channel cryogenic 3D printing scaffold for mandibular defect repair
AbstractMandibular defect repair has always been a clinical challenge, facing technical bottleneck. The new materials directly affect technological breakthroughs in mandibular defect repair field. Our aim is to fabricate a scaffold of advanced biomaterials for repairing of small mandibular defect. Therefore, a novel dual-channel scaffold consisting of silk fibroin/collagen type-I/hydroxyapatite (SCH) and polycaprolactone/hydroxyapatite (PCL/HA) was fabricated by cryogenic 3D printing technology with double nozzles. The mechanical properties and behaviors of the dual-channel scaffold were investigated by performing uniaxial...

Stability of radiomic features from positron emission tomography images: a phantom study comparing advanced reconstruction algorithms and ordered subset expectation maximization
In this study, we compared the repeatability and reproducibility of radiomic features obtained from positron emission tomography (PET) images according to the reconstruction algorithm used —advanced reconstruction algorithms, such as HYPER iterative (IT), HYPER deep learning reconstruction (DLR), and HYPER deep progressive reconstruction (DPR), or traditional Ordered Subset Expectation Maximization (OSEM)—to understand the potential variations and implications of using advanced re construction techniques in PET-based radiomics. We used a heterogeneous phantom with acrylic spherical beads (4- or 8-mm diameter) filled wi...

Comparative Simulation Study of InGaN and Silicon Channel Stack Oxide Twin Gate Field Effect Transistor Based Ammonia Gas Sensor
AbstractThis work reports a comparative analysis between Indium Gallium Nitride (InGaN) channel stack oxide twin gate field effect transistor (SO-TG-FET) and Silicon (Si) channel stack oxide twin gate field effect transistor for the detection of ammonia (NH3) gas. Catalytic metal gate of Cobalt (Co) with stacking of SiO2/HfO2 is used to detect presence of NH3.The interaction of ammonia gas molecules with Co metal gate of SO-TG-FET causes a remarkable variation in the sensitivity parameters like drain current (OFF and ON), surface potential, threshold voltage, switching ratio and transconductance. The OFF current sensitivit...

Habituation of Brain Activity with Repetition in Color and Picture-Word Stroop Tests
Ann Biomed Eng. 2024 Apr 15. doi: 10.1007/s10439-024-03509-w. Online ahead of print.ABSTRACTAs a widely used mental task for functional near-infrared spectroscopy (fNIRS), the original color-word Stroop task has the advantage of being difficult to habituate, but also the disadvantage of being difficult to understand, especially for children. While the introduction of derived Stroop tasks offers highly promising countermeasures, changes in brain activity during these tests have not been well tested. We investigated the degree of habituation between the original and a derived Stroop task by measuring brain activity to obtain...

A Quick Method to Assess Airway Distensibility in Mice
Ann Biomed Eng. 2024 Apr 15. doi: 10.1007/s10439-024-03518-9. Online ahead of print.ABSTRACTAirway distensibility is defined as the ease whereby airways are dilating in response to inflating lung pressure. If measured swiftly and accurately, airway distensibility would be a useful readout to parse the various elements contributing to airway wall stiffening, such as smooth muscle contraction, surface tension, and airway remodeling. The goal of the present study was to develop a method for measuring airway distensibility in mice. Lungs of BALB/c and C57BL/6 mice from either sex were subjected to stepwise changes in pressure....
