Temperature is the most significant parameter that plays a key role in the distribution of microorganisms on our planet. Psychrophilic microorganisms are the most prominent inhabitants of the cold ecosystems, and they possess potential cold-active enzymes with diverse uses in the research and commercial sectors. Psychrophiles are modified to nurture, replicate, and retain their active metabolic activities in low temperatures. Their enzymes possess characteristics of maximal activity at low to adequate temperatures; this feature makes them more appealing and attractive in biotechnology. The high enzymatic activity of psychrozymes at low temperatures implies an important feature for energy saving. These enzymes have proven more advantageous than their mesophilic and thermophilic counterparts. Therefore, it is very important to explore the efficiency and utility of different psychrozymes in food processing, pharmaceuticals, brewing, bioremediation, and molecular biology. In this review, we focused on the properties of cold-active enzymes and their diverse uses in different industries and research areas. This review will provide insight into the areas and characteristics to be improved in cold-active enzymes so that potential and desired enzymes can be made available for commercial purposes.

Nutraceuticals are now garnering a lot of interest because of their nutritional and therapeutic benefits. The research indicating the relevance of nutraceuticals as a possible therapeutic candidate against inflammatory lung disease was covered in this review. Nowadays, inflammatory lung diseases such as chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, asthma, pneumonia, lung cancer, becoming highly dreadful because of their associated fatality. Inflammation is one of the cores and common factors of these diseases which is mainly associated with nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) activation, NF-κB p65 and nuclear factor of kappa light polypeptide gene enhancer in B- cells inhibitor, alpha (IκBα) phosphorylation, and initiation of the signaling pathway of the NF-κB. The secondary metabolites from natural sources are the active component that attenuates NF-κB and the associated pathway that inhibits inflammation in lung diseases. Nutraceuticals belonging to the chemical category polyphenols, alkaloids, terpenoids, flavonoids, tannins have the potential to combat the NF-κB pathway. Accordingly, this review discusses the medical value of nutraceuticals briefly and their ability to mitigate various inflammatory lung diseases through targeting inhibition of NF-κB

process, the multiplication of cells in the stroma, and the creation of scar tissue. In addition to the initial damage,
the subsequent decrease in cardiac myocytes adds to heart failure. Piezo1 is remarkably understudied in the
heart, which may be related to its recent discovery. Despite this, Piezo1 is expressed in a variety of cardiovascular
cell populations, notably epithelial cells (EC), cardiac fibroblasts (CF), and cardiac myocytes (CM), in both animal and human samples, with fibroblasts expressing more than myocytes. Researchers have recently shown that
disrupting Piezo1 signaling causes defects in zebrafish developing the outflow tract (OFT) and aortic valves.
Platelet plasma membranes may provide lipid substrates, such as phosphatidylinositol bisphosphate, that aid in
activating the piezo 1 ion channel in the cardiovascular system. In addition, CXC chemokine ligand 8/CXC
chemokine receptor 1/2 (CXCL8-CXCR1/2) signaling was identified to establish the proliferation of coronary
endothelial cells during cardiac regeneration. Notably, all these pathways are calcium-dependent, and cell
proliferation and angiogenesis were necessary to recover myocardial cells. This review will examine the most
current findings to understand further how platelet-rich plasma (PRP) and the piezo 1 channel might aid in
cardiomyocyte regeneration.

pharmaceutical device manufacturing has gained significant momentum for maintaining human health. From
various available technologies, internet of things (IoT)
sensors are being increasingly used as wearable devices
(e.g., smart watches, wrist bands, mobile phones, tablets,
implantable pumps, etc.) that enable real-time monitoring
of data. Such devices are integrated with smart materials
that typically monitor the real-time data (blood pressure,
blood sugar, heart and pulse rate, cytokine levels, etc.) to
advise patients and physicians. Hence, there has been a
great demand for wearable devices as potential tools for
remote clinical trial monitoring in cancers and other
diseases and they are proving to be very cost-effective.
