One of the greatest threats to the global world is infectious diseases. The morbidity and fatality of infectious diseases cause 17 million deaths annually. The recent COVID-19 pandemic describes the uncertain potential of these diseases. Understanding the pathogenesis of infectious agents, including bacteria, viruses, fungi, etc. and the evolution of rapid diagnostic techniques and treatments has become a pressing priority to Read More

The pathogenesis of SARS-CoV-2 infection is related to the direct cytopathic effect and associated hyper-inflammation due to exaggerated immune response. Different experimental and clinical studies revealed that many biomarkers could be used to determine the Covid-19 severity, such as Ddimer, procalcitonin, C-reaction protein (CRP), IL-6, and ferritin. Calprotectin (CP) is associated with intestinal inflammation, intestinal i Read More

Natriuretic peptide system (NPS) is a group of peptide hormones or paracrine factors, including atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and natriuretic peptide precursor C (NPC), that are structurally related. The physiological effects of NPS include natriuresis, increased glomerular filtration rate, inhibition release of renin, vasopressin, and aldosterone, sympathetic inhibition, vasodilatations, and Read More

Breast cancer is the most common cancer affecting women's health, and its incidence rate is continuously increasing. With the development of immunohistochemistry and gene expression microarray technology, the study on breast cancer has gradually advanced, contributing to the development of targeted therapy for breast cancer. At present, the popular breast cancer cell surface markers includeG protein-couple Read More

Background: Biliverdin (BV) containing far-red light photoactivatable near-infrared fluorescent protein (NIR-FP) named PAiRFP1 has been developed by directed molecular evolution from one bathy bacteriophytochrome of Agrobacterium tumefaciens C58 called Agp2 or AtBphP2. Usually, the fluorescence intensity of the NIR emission spectra of PAiRFP1 tends to increase upon repeated excitation by far-red light. Objective: This Read More

Background: Infection caused by multidrug-resistant K. pneumoniae is regarded as a severe public health concern worldwide, with most countries reporting an increase in fatality rates over time. Efflux pumps are significant determinants of acquired and/or intrinsic resistance in K. pneumoniae. Objectives: Our aim is to explore efflux-mediated resistance mechanisms in K. pneumoniae by using quantitative real-time PCR in order Read More
