Since the outbreak of highly virulent coronaviruses, significant interest was assessed to the brain and heart axis (BHA) in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-affected patients. The majority of clinical reports accounted for unusual symptoms associated with SARS-CoV-2 infections which are of the neurological type, such as headache, nausea, dysgeusia, anosmia, and cerebral infarction. The SARS-CoV-2 enters the cells through the angiotensin-converting enzyme (ACE-2) receptor. Patients with prior cardiovascular disease (CVD) have a higher risk of COVID-19 infection and it has related to various cardiovascular (CV) complications. Infected patients with pre-existing CVDs are also particularly exposed to critical health outcomes. Overall, COVID-19 affected patients admitted to intensive care units (ICU) and exposed to stressful environmental constraints, featured with a cluster of neurological and CV complications. In this review, we summarized the main contributions in the literature on how SARS-CoV-2 could interfere with the BHA and its role in affecting multiorgan disorders. Specifically, the central nervous system involvement, mainly in relation to CV alterations in COVID-19-affected patients, is considered. This review also emphasizes the biomarkers and therapy options for COVID-19 patients presenting with CV problems. 相似文献

Serum collagen type IV (COLIV) is a promising tumor marker. High COLIV concentrations have been found in the serum of patients with colorectal, gastric, lung, liver and breast cancers. The aim of this work was to develop a biosensor for use with the Surface Plasmon Resonance Imaging (SPRI) technique for COLIV determination. The biosensor consists of glass covered with gold and immobilized monoclonal mouse anti-human collagen type IV antibody via cysteamine linker. The biosensor works selectively within a dynamic response range between 10 and 300 ng mL−1, with LOD 2.4 ng mL−1 and LOQ 8 ng mL−1. The precision of determination is 4.7% at a 150 ng mL−1 COLIV spike and 8.0% at a 20 ng mL−1 spike, with recoveries of 101% and 106% respectively. A 100-fold excess of collagen I, albumin, laminin and fibronectin is tolerated. The average COLIV blood plasma concentration of healthy donors determined by the developed method was 69 ± 10 ng mL−1, while the median of six results available in the literature was approximately 80 ng mL−1. The average COLIV blood plasma concentration of breast cancer patients was 360 ± 68 ng mL−1, showing the high potential of COLIV as a marker of this type of cancer. 相似文献

To create a framework for genetic dissection of hexaploid triticale, six populations of doubled haploid (DH) lines were developed from pairwise hybrids of high-yielding winter triticale cultivars. The six populations comprise between 97 and 231 genotyped DH lines each, totaling 957 DH lines. A consensus genetic map spans 4593.9 cM is composed of 1576 unique DArT markers. The maps reveal several structural rearrangements in triticale genomes. In preliminary tests of the populations and maps, markers specific to wheat segments of the engineered rye chromosome 1R (RM1B) were identified. Example QTL mapping of days to heading in cv. Krakowiak revealed loci on chromosomes 2BL and 2R responsible for extended vernalization requirement, and candidate genes were identified. The material is available to all parties interested in triticale genetics. 相似文献
