  • Flexible Pressure Sensor Array with Multi-Channel Wireless Readout Chip 28/05/2022
    Flexible sensor arrays are widely used for wearable physiological signal recording applications. A high density sensor array requires the signal readout to be compatible with multiple channels. This paper presents a highly-integrated remote health monitoring system integrating a flexible pressure sensor array with a multi-channel wireless readout chip. The custom-designed chip features 64 voltage readout […]

  • Microclimatic Evaluation of Five Types of Colombian Greenhouses Using Geostatistical Techniques 28/05/2022
    In Colombia, the second-largest exporter of cut flowers worldwide and one of the South American countries with the largest area of crops under cover, passive or naturally ventilated greenhouses predominate. Locally, there are several types of greenhouses that differ in architecture, size, height, shape of roof and ventilation surfaces, of which many characteristics of the […]

  • A Review of Noninvasive Methodologies to Estimate the Blood Pressure Waveform 28/05/2022
    Accurate estimation of blood pressure (BP) waveforms is critical for ensuring the safety and proper care of patients in intensive care units (ICUs) and for intraoperative hemodynamic monitoring. Normal cuff-based BP measurements can only provide systolic blood pressure (SBP) and diastolic blood pressure (DBP). Alternatively, the BP waveform can be used to estimate a variety […]

  • Solar Energy Harvesting to Improve Capabilities of Wearable Devices 28/05/2022
    The market of wearable devices has been growing over the past decades. Smart wearables are usually part of IoT (Internet of things) systems and include many functionalities such as physiological sensors, processing units and wireless communications, that are useful in fields like healthcare, activity tracking and sports, among others. The number of functions that wearables […]

  • SARS-CoV-2 Virion Infectivity and Cytokine Production in Primary Human Airway Epithelial Cells 28/05/2022
    The emergence of new SARS-CoV-2 variants and the replacement of preceding isolates have been observed through B.1.1.7, B.1.351, B.1.617.2, and B.1.1.529 lineages (corresponding to alpha, beta, delta, and omicron variants of concern (VoC), respectively). However, there is still a lack of biological evidence to which extent those VoC differ from the ancestral lineages. By exploiting […]

  • Silicone-Textile Composite Resistive Strain Sensors for Human Motion-Related Parameters 28/05/2022
    In recent years, soft and flexible strain sensors have found application in wearable devices for monitoring human motion and physiological parameters. Conductive textile-based sensors are good candidates for developing these sensors. However, their robust electro-mechanical connection and susceptibility to environmental factors are still an open challenge to date. In this work, the manufacturing process of […]

  • Nutrition and stem cell integrity in aging 28/05/2022
    Adult stem cells (SCs) represent the regenerative capacity of organisms throughout their lifespan. The maintenance of robust SC populations capable of renewing organs and physiological systems is one hallmark of healthy aging. The local environment of SCs, referred to as the niche, includes the nutritional milieu, which is essential to maintain the quantity and quality […]

  • A Rare Presentation of Extramedullary Hematopoiesis: Perirenal Masses 28/05/2022
    Extramedullary hematopoiesis (EMH) is a physiological compensatory mechanism that develops in response to ineffective or insufficient hematopoiesis. Although the liver and spleen are the most common sites, EMH may occur anywhere in the body. Peri-renal involvement in EMH is quite rare and mimics tumoral lesions. To our knowledge, 12 peri-renal EMH cases have been reported […]

  • Shrimp peptide hydrolysate modulates the immune response in cyclophosphamide immunosuppressed mice model 28/05/2022
    Bioactive peptides are naturally found in various foods and were shown to have various distinct physiological as well as medicinal benefits. In this study shrimp peptide hydrolysate (SPH) was prepared to investigate its immunomodulatory effect against cyclophosphamide (CTX) induced immunosuppressed mice. The SPH effect was also analyzed on murine macrophage (RAW264.7 cells). The findings show […]

  • Seasonal differences in thermal stress susceptibility of diploid and triploid brook trout, S. fontinalis (Teleostei, Pisces) 28/05/2022
    Many physiological processes of teleost fish show periodicity due to intrinsic rhythms. It may be hypothesized that also susceptibility to thermal stress differs seasonally. To shed more light on this problem the following experiment was conducted. Diploid and triploid S. fontinalis were kept at an acclimation temperature of 9°C and at a natural photoperiod typical […]
