Abstract
Introduction Dyspnea is among the most prevalent symptoms experienced by patients presenting as an emergency. The underlying etiology is often a cardiovascular or pulmonary condition, of which heart failure is recognized as a major contributor. The differentials are primarily established based on the patient's clinical presentation and physical examinations but are not conclusive. Of the various investigations undertaken to determine the cause of dyspnea, the biomarker N-Terminal Pro-B-Type Natriuretic Peptide (NT-proBNP) was found to be significantly associated with heart failure. Its level has been proven to be in direct correlation with the severity of the disease. This study demonstrates the usability of an economical rapid test kit in measuring NT-ProBNP levels to help differentiate the cause of dyspnea in the presenting patient in a resource-limited setting. Methodology We studied 115 participants from a tertiary care center in India, which included 70 males and 45 females aged ≤30 to ≥75 years, presenting with shortness of breath. Rapid NT-ProBNP tests were conducted alongside recording their symptoms, vitals, examination findings, and other parameters. They were also classified according to New York Heart Association (NYHA) Classification, and further investigated. Results The study elucidated the efficacy and accuracy of the rapid kits in determining NT-ProBNP levels, and its relation with the severity and prognosis of heart failure. The kits utilized had a sensitivity of greater than 93% for ruling out heart failure as a cause of dyspnea, and a sensitivity of greater than 96% for ruling out elevated NT-ProBNP levels in general. Other parameters such as presenting symptoms and vitals were also analyzed, establishing a correlation with NT-ProBNP levels. Conclusion This study guided us in understanding the effective utilization of the rapid testing kits for emergency care, minimizing the burden on other limited resources. The lower cost and ease of use would serve as a quick means of reaching a conclusive diagnosis, especially in an emergency, which in turn would aid in receiving timely and specific treatment. These kits could act as a stepping stone in creating a sustainable and efficient healthcare system for patients as well as healthcare workers.

Abstract
Chronic pulmonary diseases such as asthma, COPD, and Idiopathic pulmonary fibrosis are significant causes of mortality and morbidity worldwide. Currently, there is no radical treatment for many chronic pulmonary diseases, and the treatment options focus on relieving the symptoms and improving lung function. Therefore, efficient therapeutic agents are highly needed. Bronchial epithelial cells and airway smooth muscle cells and their crosstalk play a significant role in the pathogenesis of these diseases. Thus, targeting the interactions of these two cell types could open the door to a new generation of effective therapeutic options. However, the studies on how these two cell types interact and how their crosstalk adds up to respiratory diseases are not well established. With the rise of modern research tools and technology, such as lab-on-a-chip, organoids, co-culture techniques, and advanced immunofluorescence imaging, a substantial degree of evidence about these cell interactions emerged. Hence, this contribution aims to summarize the growing evidence of bronchial epithelial cells and airway smooth muscle cells crosstalk under normal and pathophysiological conditions. The review first discusses the impact of airway smooth muscle cells on the epithelium in inflammatory settings. Later, it examines the role of airway smooth muscle cells in the early development of bronchial epithelial cells and their recovery after injury. Then, it deliberates the effects of both healthy and stressed epithelial cells on airway smooth muscle cells, taking into account three themes; contraction, migration, and proliferation.

Abstract
The skeletal development process in the body occurs through sequential cellular and molecular processes called endochondral ossification. Endochondral ossification occurs in the growth plate where chondrocytes differentiate from resting, proliferative, hypertrophic to calcified zones. Natriuretic peptides (NPTs) are peptide hormones with multiple functions, including regulation of blood pressure, water-mineral balance, and many metabolic processes. NPTs secreted from the heart activate different tissues and organs, working in a paracrine or autocrine manner. One of the natriuretic peptides, C-type natriuretic peptide-, induces bone growth through several mechanisms. This review will summarize the knowledge, including the newest discoveries, of the mechanism of CNP activation in bone growth.
