Key Aspects

Cardiac tissue engineering aims at creating contractile structures that can optimally reproduce the features of human cardiac tissue. These constructs are becoming valuable tools to model some of the cardiac functions, to set preclinical platforms for drug testing, or to alternatively be used as therapies for cardiac repair approaches. Most of the recent developments in cardiac tissue engineering have been made possible by important advances regarding the efficient generation of cardiac cells from pluripotent stem cells and the use of novel biomaterials and microfabrication methods. Different combinations of cells, biomaterials, scaffolds, and geometries are however possible, which results in different types of structures with gradual complexities and abilities to mimic the native cardiac tissue. Here, we intend to cover key aspects of tissue engineering applied to cardiology and the consequent development of cardiac organoids. This review presents various facets of the construction of human cardiac 3D constructs, from the choice of the components to their patterning, the final geometry of generated tissues, and the subsequent readouts and applications to model and treat cardiac diseases.

Abstract We report the use of Levosimendan, calcium sensitizer, inodilator in a neonate with post-operative refractory cardiogenic shock. Currently, no data are available on the use of levosimendan in newborns outside the cardiosurgical setting. A 38-week neonate -with isolated exomphalos major-presented post-operatively with pulmonary hypertension, refractory cardiogenic shock (inspite of receiving, a bolus of 10ml/kg, Dopamine and Dobutamine 15µg/kg/min, Adrenaline up to 1mg/Kg/min, Noradrenaline 0.5mg/Kg/min, Terlipressin 20µg/Kg/hour, Milrinone 25µg/Kg/min) and arrhythmia (supraventricular tachycardia). Levosimendan was introduced as an intravenous infusion with an initial rate of 0.1 up to 0.2µg/Kg/min in addition to Noradrenaline 1µg/Kg/min, Dopamine 15µg/Kg/min and Furosemide infusion 0.1mg/Kg/hour. The patient improved evidenced by normalization of vital signs and restoration of perfusion with better cardiac functions by echocardiography. Conclusion: Levosimendan has positive inotropic, lusitropic and vasodilating effects for the treatment of heart failure yet further studies in neonates are still required.

ABSTRACT Cadmium (Cd) is a well-known nephrotoxic agent. Cd-induced renal dysfunction has been considered as one of the causes leading to the development of hypertension. The correlation between Cd concentration in blood and urine and cardiovascular diseases has been discussed in many epidemiological studies. A therapy with chelating agents is utilized for the treatment of toxic metal intoxication. Herein we present novel information indicating that monensin (applied as tetraethylammonium salt) is a promising chelating agent for the treatment of Cd-induced renal and cardiac dysfunction. The study was performed using the ICR mouse model. Adult ICR male mice were divided into three groups with six animals in each group: control (received distilled water and food ad libitum for 28 days); Cd-intoxicated (treated orally with 20 mg/kg b.w. Cd(II) acetate from day 1 to day 14 of the experimental protocol), and monensin treated group (intoxicated with Cd(II) acetate as described for the Cd-intoxicated group followed by oral treatment with 16 mg/kg b.w. tetraethylammonium salt of monensic acid for 2 weeks). Cd intoxication of the animals resulted in an increase of the organ weight/body weight indexes. Cd elevated significantly creatinine and glucose level in serum. Monensin treatment improved the organ weight/body weight ratios. The therapy of the Cd-intoxicated animals with monensin ameliorated the creatinine and glucose level in serum and decreased the concentration of the toxic metal ions in the heart and kidneys by 54 % and 64 %, respectively

Conductive Properties

Abstract Highly stretched and conductive hydrogels, especially synthetized from natural polymers, are beneficial for highly stretched electronic equipment which is applied in extreme environment. We designed and prepared robust and tough alginate hydrogels (GMA-SA-PAM) using the ingenious strategy of fully interpenetrating cross-linking, in which the glycidyl methacrylate (GMA) was used to modify sodium alginate (SA) and then copolymerized with acrylamide (AM) and methylenebisacrylamide (BIS) as cross-linkers. The complete cross-linked structures can averagely dissipate energy and the polymer structures can maintain hydrogels that are three-dimensional to greatly improve the mechanical performance of hydrogels. The GMA-SA-PAM hydrogels display ultra-stretchable (strain up to ∼407% of tensile strain) and highly compressible (∼57% of compression strain) properties. In addition, soaking the GMA-SA-PAM hydrogel in 5 wt% NaCl solution also endows the conductivity of the hydrogel (this hydrogel was named as GSP-Na) with excellent conductive properties (5.26 S m−1). The GSP-Na hydrogel with high stability, durability, as well as wide range extent sensor is also demonstrated by researching the electrochemical signals and showing the potential for applications in wearable and quickly responded electronics.
