Oxygenated machine perfusion of human organs has been shown to improve both preservation quality and time duration when compared to the current gold standard static cold storage. However, existing machine perfusion devices designed for preservation and transportation of transplantable organs are too complicated and organ-specific to merit use as a solution for all organs. This work presents a novel, portable, and nonelectronic device potentially capable of delivering oxygenated machine perfusion to a variety of organs. An innovative pneumatic circuit system regulates a compressed oxygen source that cyclically inflates and deflates silicone tubes, which function as both the oxygenator and perfusion pump. Different combinations of silicone tubes in single or parallel configurations, with lengths ranging from 1.5 to 15.2 m, were evaluated at varying oxygen pressures from 27.6 to 110.3 kPa. The silicone tubes in parallel configurations produced higher peak perfusion pressures (70% increase), mean flow rates (102% increase), and oxygenation rates (268% increase) than the single silicone tubes that had equivalent total lengths. While pumping against a vascular resistance element that mimicked a kidney, the device achieved perfusion pressures (8.4-131.6 mmHg), flow rates (2.0-40.2 mL min-1), and oxygenation rates (up to 388 μmol min-1) that are consistent with values used in previous kidney preservation studies. The nonelectronic device achieved those perfusion parameters using 4.4 L min-1 of oxygen to operate. These results demonstrate that oxygenated machine perfusion can be successfully achieved without any electronic components.

Lung Ultrasound Score (LUS) identifies and monitors pneumonia by assigning increasing scores. However, it does not include parameters, such as inferior vena cava (IVC) diameter and index of collapse, diaphragmatic excursions and search for pleural and pericardial effusions. Therefore, we propose a new improved scoring system, termed "integrated" lung ultrasound score (i-LUS) which incorporates previously mentioned parameters that can help in prediction of disease severity and survival, choice of oxygenation mode/ventilation and assignment to subsequent areas of care in patients with COVID-19 pneumonia.

Upon admission at the sub-intensive section of the emergency medical department (SEMD), 143 consecutively examined COVID-19 patients underwent i-LUS together with all other routine analysis. A database for anamnestic information, laboratory data, gas analysis and i-LUS parameters was created and analyzed.

Of 143 enrolled patients, 59.4% were male (mean age 71years) and 40.6% female. (mean age 79years p =  be used as a helpful clinical tool for early decision-making in patients with COVID-19 pneumonia.

i-LUS could be used as a helpful clinical tool for early decision-making in patients with COVID-19 pneumonia.

The management of diabetes has been revolutionized by the introduction of novel technological treatments and modalities of care, such as continuous glucose monitoring, insulin pump therapy, and telehealth. While these technologies have demonstrated improvement in health outcomes, it remains unclear whether they have reduced inequities from racial/ethnic minority or socioeconomic status. We review the current literature to discuss evidence of benefit, current limitations, and future opportunities of diabetes technologies.

While there is ample evidence of the health and psychological benefit of diabetes technologies in large populations of people with type 1 and type 2 diabetes, there remain wide disparities in the use of diabetes technologies, which may be perpetuating or widening inequities. Multilevel barriers include inequitable prescribing practices, lack of support for social determinants of health, mismatch of patient preferences and care models, and cost. We provide a review of disparities in diabetes technology use, possible root causes of continued inequity in outcomes, and insight into ways to overcome remaining gaps.

Withania somnifera (L.) Dunal, the herb from family Solanaceae is one of the most treasured medicinal plant used in traditional medicinal systems owing to its unique stockpile of pharmaceutically active secondary metabolites. Phytochemical and pharmacological studies in this plant were well established, but the genes affecting the regulation of biosynthesis of major metabolites were not well elucidated. In this study cloning and functional characterization of a key enzyme in terpenoid biosynthetic pathway viz. geranylgeranyl pyrophosphate synthase (EC 2.5.1.29) gene from Withania somnifera was performed. The full length WsGGPPS gene contained 1,104 base pairs that encode a polypeptide of 365 amino acids. The quantitative expression analysis suggested that WsGGPPS transcripts were expressed maximally in flower tissues followed by berry tissues. The expression levels of WsGGPPS were found to be regulated by methyl jasmonate (MeJA) and salicylic acid (SA). Amino acid sequence alignment and phylogenetic studies suggested that WsGGPPS had close similarities with GGPPS of Solanum tuberosum and Solanum pennellii. The structural analysis provided basic information about three dimensional features and physicochemical parameters of WsGGPPS protein. Overexpression of WsGGPPS in planta for its functional characterization suggested that the WsGGPPS was involved in gibberellic acid biosynthesis.Fungi are a small but important part of the human microbiota and several fungi are familiar to the immune system, yet certain can cause infections in immunocompromised hosts and referred as opportunistic pathogens. The fungal coinfections in COVID-19 hosts with predisposing conditions and immunosuppressive medications are posing higher severity and death. The immunological counteraction (innate/adaptive immunity) is triggered when the PRRs on the host cells recognize the fungal PAMPs. However, in simultaneous infections (COVID-19 and fungal coinfection), the synergism of TLR and NLR may hyperactivate the immune cells which dramatically increase the cytokine level and generate cytokine storm. Fungal colonization in the human gut assists the development of microbiome assembly, ecology, and shaping immune response. However, SARS-CoV-2 infection represented unstable mycobiomes and long-term dysbiosis in a large proportion in COVID-19 patients. Normally, amphotericin B is considered as first-line treatment for invasive fungal infection. So, amphotericin B therapy is recommended in COVID-19 hosts with serious fungal infections. Still, the long-term corticosteroid supplementation prescribed in case of severe pneumonia and lower oxygen levels may result in systemic fungal infection in COVID-19 patients, eventually limiting the lifesaving benefits of available medications. Also, due to the evolution of fungal resistance to available antibiotics, the current treatments are becoming ineffective. Therefore, this review summarizes the concerns, needed to deal with the impending crises.Magnetic nanoparticles (MNPs) have been used for purification of specific biomolecules form mixtures. The aim of this study is to develop a new, cheap, reusable, and magnetic-based material to purify the carbonic anhydrase (CA) enzyme in a short time with high efficiency. In the first part of this study, silica-coated iron oxide magnetic nanoparticles (Fe3O4@SiO2 MNPs) were obtained. Surface modification of Fe3O4@SiO2 MNPs was accomplished with 3-(4-Hydroxyphenyl) propionic acid (PA) and sulfanilamide (SA), respectively. SA is a selective inhibitor of CA, and it selectively binds to CA. The final particle was named Fe3O4@SiO2-PA-SA MNPs and characterized by SEM, TEM, XRD, and FT-IR. Compound 9 It was determined that the produced MNPs contained multicore, were smaller than 100 nm in size, and had a spherical morphology. The CA was purified from bovine blood hemolysate in a short time such as 2.5 h and in a simple manner. The maximum enzyme purifying capacity of MNPs was calculated as 13.87 ± 3.27 mg CA/g MNP. SDS-PAGE analysis was confirmed that high CA purification success was achieved.Alzheimer's disease (AD) is associated with dysregulated immune and inflammatory responses. Emerging evidence indicates that peripheral immune activation is linked to neuroinflammation and AD pathogenesis. The present study focuses on determining the role of IL-21 in the pathogenesis of AD using human samples and the 5xFAD mice model. We find that the levels of IL-21 are increased in the periphery of both humans and mice in AD. In addition, the proportions of IL-21 target cells, Tfh and B plasma cells as well as activation of monocytes is increased in PBMCs from AD and mild cognitively impaired (MCI) subjects as compared to age-matched controls, indicating immune activation. In contrast, the percentage of B1 cells that control inflammation is decreased. These changes are due to IL-21 as the expression of IL-21 receptor (IL-21R) is higher on all these cells in AD. Furthermore, treatment with recombinant IL-21 in AD mice also leads to similar alterations in Tfh, B, B1, and macrophages. The effect of IL-21 is nof Tfh and B plasma cells indicative of peripheral immune activation. On the other hand, the proportions of B1 cells that help reduce inflammation and clear Aβ are reduced. In addition to the periphery, IL-21 also acts on the brain via IL-21 receptor, IL-21R that displays increased expression in the hippocampi of AD and MCI subjects. IL-21 enhances the activation of microglia, induces the secretion of pro-inflammatory cytokines and deposition of Aβ plaques in the brain in AD.

Hospitalizations for acute decompensated heart failure (ADHF) are commonly associated with congestion-related signs and symptoms. Objective and quantitative markers of congestion have been identified, but there is limited knowledge regarding the correlation between these markers.

Patients hospitalized for ADHF irrespective of left ventricular ejection fraction were included in a prospective registry. Assessment of congestion markers (e.g., NT-proBNP, maximum inferior vena cava diameter, dyspnea using visual analogue scale, and a clinical congestion score) was performed systematically on admission and at discharge. Telephone interviews were performed to assess clinical events, i.e., all-cause death or readmission for cardiovascular cause, after discharge. Missing values were handled by multiple imputation.

In total, 130 patients were prospectively enrolled. Median length of hospitalization was 9days (interquartile range 6 to 16). All congestion markers declined from admission to discharge (p < 0.001).
