    Abstract Coronavirus outbreak was declared a pandemic by World Health Organization (WHO) in March 2020. The pandemic has led to a devastating loss of life. It has shown us how infectious diseases can cause human existence at stake, and community health is important. The spike protein is the most immunogenic component of the virus. Most vaccine development strategies have focused on the receptor-binding domain (RBD) in the spike protein because it is the most specific target site that recognizes and interacts with human lung cells. Neutralizing antibodies are generated by the humoral immune system and reduce the viral load by binding to spike protein components. Neutralizing antibodies are the proteins secreted by plasma cells and serve as an important part of the defense mechanism. In the recent Covid-19 infection, neutralizing antibodies can be utilized for both diagnostic such as immune surveillance and therapeutic tools such as plasma therapy. So far, many monoclonal antibodies are in the clinical trial phase, and few of them are already in use. In this review, we have discussed details about neutralizing antibodies and their role in combating Covid-19 disease.

    Abstract An impedance sensing system is a family of biosensors that measure changes in electrical impedance to perform their functions. Physical and chemical changes in the impedance of the sensing element, such as changes in the concentration of a target analyte or changes in the physical properties of the sensing element, can result in changes in the impedance of the sensing element. Many impedance biosensors have been developed for the detection of pathogens in the past few decades. Several types of biosensors have been developed for the detection of infections, including transduction elements, biorecognition components, and electrochemical approaches. In this review, we discuss the characteristics and pathogenic factors associated with 2,3-butanediol-producing

    Abstract Telomerase is a specialized enzyme which maintains telomere length at the extreme end of the chromosome. Over 90% of all cases of cancer show high expression of telomerase while in normal cells, its expression is extremely low or undetectable. Detection of telomerase activity in a wide range of breast cancer makes telomerase an interesting target for diagnosis and therapy. In this review, we have aimed to describe telomerase as a therapeutic and accurate diagnostic target in breast cancer. Telomerase performs many extracurricular activities apart from maintaining telomere length; here, we have also tried to address its role in epithelialmesenchymal transition (EMT) of breast cancer progression.

    Abstract SARS-CoV-2, a novel coronavirus, causes respiratory tract infections and other complications in affected individuals, and has resulted in numerous deaths worldwide. The unprecedented pace of its transmission worldwide, and the resultant heavy burden on healthcare systems everywhere, prompted efforts to have effective therapeutic strategies and vaccination candidates available to the global population. While aged and immunocompromised individuals form a high-risk group for COVID-19 and have severe disease outcome, the rate of infections among children has also increased with the emergence of the Omicron variant. In addition, recent reports of threatening SARS-CoV-2-associated complications in children have brought to the forefront an urgent necessity for vaccination. In this article, we discuss the current scenario of SARS-CoV-2 infections in children with a special focus on the differences in their immune system response as compared to adults. Further, we describe the various available COVID-19 vaccines, including the recent bivalent vaccines for children, in detail, intending to increase willingness for their acceptance.

    Abstract Keeping replication fork stable is essential for safeguarding genome integrity; hence, its protection is highly regulated. The CTC1-STN1-TEN1 (CST) complex protects stalled forks from aberrant MRE11-mediated nascent strand DNA degradation (NSD). However, the activation mechanism for CST at forks is unknown. Here, we report that STN1 is phosphorylated in its intrinsic disordered region. Loss of STN1 phosphorylation reduces the replication stress-induced STN1 localization to stalled forks, elevates NSD, increases MRE11 access to stalled forks, and decreases RAD51 localization at forks, leading to increased genome instability under perturbed DNA replication condition. STN1 is phosphorylated by both the ATR-CHK1 and the calcium-sensing kinase CaMKK2 in response to hydroxyurea/aphidicolin treatment or elevated cytosolic calcium concentration. Cancer-associated STN1 variants impair STN1 phosphorylation, conferring inability of fork protection. Collectively, our study uncovers that CaMKK2 and ATR-CHK1 target STN1 to enable its fork protective function, and suggests an important role of STN1 phosphorylation in cancer development.

    Abstract SARS-CoV-2 (COVID-19) pandemic has been an unpredicted burden on global healthcare system by infecting over 700 million individuals, with approximately 6 million deaths worldwide. COVID-19 significantly impacted all sectors, but it very adversely affected the healthcare system. These effects were much more evident in the resource limited part of the world. Individuals with acute conditions were also severely impacted. Although classical COVID-19 diagnostics such as RT-PCR and rapid antibody testing have played a crucial role in reducing the spread of infection, these diagnostic techniques are associated with certain limitations. For instance, drawback of RT-PCR diagnostics is that due to degradation of viral RNA during shipping, it can give false negative results. Also, rapid antibody testing majorly depends on the phase of infection and cannot be performed on immune compromised individuals. These limitations in current diagnostic tools require the development of nanodiagnostic tools for early detection of COVID-19 infection. Therefore, the SARS-CoV-2 outbreak has necessitated the development of specific, responsive, accurate, rapid, low-cost, and simple-to-use diagnostic tools at point of care. In recent years, early detection has been a challenge for several health diseases that require prompt attention and treatment. Disease identification at an early stage, increased imaging of inner health issues, and ease of diagnostic processes have all been established using a new discipline of laboratory medicine called nanodiagnostics, even before symptoms have appeared. Nanodiagnostics refers to the application of nanoparticles (material with size equal to or less than 100 nm) for medical diagnostic purposes. The special property of nanomaterials compared to their macroscopic counterparts is a lesser signal loss and an enhanced electromagnetic field. Nanosize of the detection material also enhances its sensitivity and increases the signal to noise ratio. Microchips, nanorobots, biosensors, nanoidentification of single-celled structures, and microelectromechanical systems are some of the most modern nanodiagnostics technologies now in development. Here, we have highlighted the important roles of nanotechnology in healthcare sector, with a detailed focus on the management of the COVID-19 pandemic. We outline the different types of nanotechnology-based diagnostic devices for SARS-CoV-2 and the possible applications of nanomaterials in COVID-19 treatment. We also discuss the utility of nanomaterials in formulating preventive strategies against SARS-CoV-2 including their use in manufacture of protective equipment, formulation of vaccines, and strategies for directly hindering viral infection. We further discuss the factors hindering the large-scale accessibility of nanotechnology-based healthcare applications and suggestions for overcoming them.

    Abstract Measles virus is the causative agent of measles, a major cause of child mortality in developing countries. Two major proteins, coded by the viral genome, are nucleocapsid protein (N) and phosphoprotein (P). The N protein protects the viral genomic RNA and forms ribonucleoprotein complex (RNP) together with P protein. MeV-P protein recruits the large protein (L), i.e. viral RNA-depended RNA polymerase (RdRp), to ensure viral replication in host cell. Apoptogenic properties of N protein of Edmonston vaccine strain have been established in our lab previously. We investigated the role of MeV-P protein of Edmonston vaccine strain as modulator of apoptosis in cervical cancer cell line (HeLa) and found that MeV-P protein is anti-apoptotic and enhances cell proliferation. Measles virus is considered to be innately oncotropic virus. However, the anti-apoptotic property of MeV-P protein raises important concerns while adopting this virus as an anti-cancer therapeutic tool.
