Biomedical Spectroscopy and Imaging (BSI) is a multidisciplinary journal devoted to the timely publication of basic and applied research that uses spectroscopic and imaging techniques in different areas of life science including biology, biochemistry, biotechnology, bionanotechnology, environmental science, food science, pharmaceutical science, physiology and medicine. Scientists are encouraged to submit their work for publication in the form of original articles, brief communications, rapid communications, reviews and mini-reviews.
The journal is dedicated to providing a single forum for experts in spectroscopy and imaging as applied to biomedical problems, and also for life scientists who use these powerful methods for advancing their research work. BSI aims to promote communication, understanding and synergy across the diverse disciplines that rely on spectroscopy and imaging. It also encourages the submission of articles describing development of new devices and technologies, based on spectroscopy and imaging methods, for application in diverse areas including medicine, biomedical science, biomaterials science, environmental science, pharmaceutical science, proteomics, genomics, metabolomics, microbiology, biotechnology, genetic engineering, nanotechnology, etc.
Abstract: The high flexibility of the heterogeneous system based on CPU-GPU and CPU-FPGAoffer us huge performance in terms of processing time and resource optimization. We can use these systems in all areas provided that we have studied the adequacy between the algorithm and the architecture, this adequacy technique is called hardware software co-design. Today, the need for embedded systems is an irreplaceable reality, especially when we talk about real-time systems. Among the most well-known embedded systems are FPGAs, this system is based on the parallelization of algorithms via the pipline principle. In this work, we present the application of the heterogeneous…system in the biomedical field, in particular the cardiac signals provided by the electrocardiogram and the different ECG signal filtering techniques. And also, we will proposing an embedded implementation of the ADTF filter in a homogeneous architecture (FPGA). And also, the heterogeneous architecture via the HLS OpenCL.

Abstract: Fourier transform infrared (FTIR) and Raman spectroscopy are complementary techniques, typically called vibrational spectroscopy. Both techniques allow simple, rapid, non-destructive, specific, providing fingerprint spectra, and real-time analytical method for analysis of molecules in different states. Besides, these methods are simple without any excessive sample pre-treatment, therefore, they are sometimes called as “green analytical methods”. Biofluids have several biomolecules such as lipid, protein, nucleic acids, and carbohydrates. These biomolecules can be used as biomarkers to detect some types of diseases, since biomolecules are in direct contact with the human organs. FTIR and Raman spectra of biofluids are complex in nature, therefore…sophisticated statistical techniques, known as chemometrics, must be used to solve the analytical problems related to quantitative analysis purposes. The objective of this review is to show the capability of FTIR and Raman spectroscopic techniques in combination with chemometrics techniques to analyze the biomolecules in biofluids through an extensive literature review. During performing this review, several databases in Science citation index, Scopus PubMed, and Google Scholar related to the topics are identified and downloaded. With the present review, it is known that FTIR and Raman techniques are rapid method for screening certain diseases by identifying the level changes of some biomolecules. In the future, this method will be widely used for clinicians as new diagnostic tools for many diseases.
Abstract: The applications of laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) in biomedical research are progressively increasing in the last decade. The main advantage of this powerful analytical technique is the ability to perform multi-elemental analysis directly from biological samples, such as tissues, organs, and single cells, with minimal sample preparation. This feature is particularly important for studies regarding disease biomarkers and mechanism of action of drugs. In this mini-review, the recent advances in the use of LA-ICP-MS for the analysis of biological samples will be discussed, as well as representative biomedical applications.

Abstract: Background: In hospitals, patients placed in Intensive Care Units need constant and close monitoring and require special equipment to ensure their normal bodily functions. The problem is how to continuously monitor each patient while ensuring the privacy of their information? And what technology to choose as a medium of wireless communication? Objective: The aim of this work is to propose a novel wireless system for surveillance in intensive care units in hospitals. This system will have no interference issue with hospital equipment and will ensure the privacy of patient information. In addition, it has many other functionalities that…facilitate patient surveillance. Methods: Interested by the challenge of the reliable transmission of visual data in the proposed system, a simulation under ns-3 is developed to evaluate the performance of the used wireless technology and to compare it with Wi-Fi channels in terms of video transmission in a Wireless Visual Sensor Network. Results: Our results reveal the high fidelity of the reconstructed videos transmitted via the used technology in our system compared to those transmitted via Wi-Fi channels. Conclusion: The proposed system will provide a high level of security, high speed of data transmission, low energy consumption and it will have no interference issue with the hospital equipment.
