Jaundice indicates yellow discoloration of skin, sclera, and mucus membrane and is a clinical indication of bilirubin accumulation in the blood which occurs as a consequence of the incapability of the liver to excrete bilirubin in the biliary tree or conjugate bilirubin and higher production of bilirubin in the body. Several methods have been developed so far for bilirubin estimation in jaundice like the spectrophotometric method, chemiluminescence method, etc., but biosensing methods provide advantages over traditional methods concerning the surface area, adsorption, particle size, and functional characteristics. The primary objective of the present research project was to formulate and examine the adsorbent nanoflowers-based biosensor for accurate, precise, and sensitive detection of bilirubin in jaundice. The particle size of adsorbent nanoflowers was found to be in the range of 300-600nm with the surface charge (zeta potential) in the range of -1.12 to -15.42 mV. Transmission electron microscopy and scanning electron microscopy images confirmed the flower-like morphological structure of adsorbent NFs. The adsorption efficiency of NFs for bilirubin adsorption was maximum at 94.13%. Comparative studies of bilirubin estimation in the pathological sample with adsorbent NFs and diagnostic kit displayed bilirubin concentration to be 1.0 mg/dL in adsorbent nanoflowers and 1.1 mg/dL with diagnostic kit indicating effective detection of bilirubin with adsorbent NFs. The nanoflower-based biosensor acts as a smart approach to elevate adsorption efficiency on the surface of nanoflower due to a higher surface-to-volume (SV) ratio.

ANP and BNP are the most relevant NPs as biomarkers for the diagnosis and prognosis of heart failure and underlying cardiovascular diseases, such as cardiac valvular dysfunction, hypertension, coronary artery disease, myocardial infarction, persistent arrhythmias, and cardiomyopathies. Cardiac dysfunctions related to cardiomyocytes stretching in the atria and ventricles are primary elicitors of ANP and BNP release, respectively. ANP and BNP would serve as biomarkers for differentiating cardiac versus noncardiac causes of dyspnea and as a tool for measuring the prognosis of patients with heart failure; nevertheless, BNP has been shown with the highest predictive value, particularly related to pulmonary disorders. Plasma BNP has been reported to help differentiate cardiac from pulmonary etiologies of dyspnea in adults and neonates. Studies have shown that COVID-19 infection also increases serum levels of N-terminal pro b-type natriuretic peptide (NT-proBNP) and BNP. This narrative review assesses aspects of ANP and BNP on their physiology, and predictive values as biomarkers. We present an overview of the NPs' synthesis, structure, storage, and release, as well as receptors and physiological roles.

In the present study, the effective mixing of nanoparticles and the blood that carries the CTCs are investigated. The mixing procedure was studied under various inlet velocity ratios and several T-shaped micromixer geometries with rectangular cavities by using computational fluid dynamics techniques. The Navier-Stokes equations were solved for the blood flow; the discrete motion of particles is evaluated by a Lagrangian method while the diffusion of blood substances is studied by using a scalar transport equation. Results showed that as the velocity ratio between the inlet streams increases, the mixing rate of nanoparticles with the blood flow is increased. Moreover, nanoparticles are uniformly distributed across the mixing channel while their concentration is decreased along the channel. Furthermore, the evolution in time of the blood substances in the mixing channel increases with the increase of the velocity ratio between the two streams. On the other hand, the concentration of both the blood substances and the nanoparticles is decreased in the mixing channel as the velocity ratio increases.

Abnormalities in the regulation of renal ion transport cause essential hypertension. The renal dopaminergic system, which inhibits sodium transport in all the nephron segments, is responsible for at least 50% of renal sodium excretion under conditions of moderate sodium excess. Dopaminergic signals are transduced by two families of receptors that belong to the G protein-coupled receptor (GPCR) superfamily. D₁-like receptors (D₁R and D₅R) stimulate, while D2-like receptors (D₂R, D₃R, and D₄R) inhibit adenylyl cyclases. The dopamine receptor subtypes, themselves, or by their interactions, regulate renal sodium transport and blood pressure. We review the role of the D₁R and D₃R and their interaction in the natriuresis associated with volume expansion. The D₁R- and D₃R-mediated inhibition of renal sodium transport involves PKA and PKC-dependent and -independent mechanisms. The D₃R also increases the degradation of NHE3 via USP-mediated ubiquitinylation. Although deletion of <i>Drd1</i> and <i>Drd3</i> in mice causes hypertension, <i>DRD1</i> polymorphisms are not always associated with human essential hypertension and polymorphisms in <i>DRD3</i> are not associated with human essential hypertension.

Presently, electrophoresis and genotyping are used as routine tests for diagnosis of SCD. These techniques are expensive and require specialized laboratories. Lab-on-a-chip technology is a low-cost microfluidics-based diagnostic tool which holds significant promise for rapid screening of RBC deformability. To explore the sickle RBC mechanics for screening purposes, we present a mathematical model for the flow of single RBC with altered rheological properties and slip effect on capillary wall in microcirculation. We consider single-file flow of cells through the axis symmetrical cylindrical duct, applying lubrication theory as plasma trapped between successive red blood cells. The rheological parameters used from published literature for normal RBC and corresponding variation has been taken for the purpose of this simulation to present the condition of the disease. An analytical solution has been found for realistic boundary conditions and results are simulated using MATLAB. We found that the height of plasma film in the capillary increases with increase in cell deformability and compliance which affects the forward flow velocity in the capillary. Rigid RBCs with increased adhesion between cell and capillary wall shows reduction in velocity and occurrence of vaso-occlusion events in extreme conditions.
