Bispecific Antibody-Based Immune-Cell Engagers in Cancer Immunotherapy
Cancer is the second leading cause of death worldwide after cardiovascular diseases. One of the most promising targeted therapies for cancer treatment is antibody therapy. It has a superior targeting ability for antigens that are expressed on cancer cells, which results in prominent antitumor activity and lower toxicity, compared with that of chemotherapeutic agents. Recent progress in recombinant DNA technology and antibody engineering has ushered in a new era of bispecific antibody (bsAb)-based immune-cell engagers (ICEs), including T- and natural-killer-cell engagers.

Breast Cancer Subtype-Specific miRNAs
Breast cancer is one of the most common malignancies, with multiple subtypes, based on clinical parameters and molecular profiling. In addition to disease staging, the expression status of hormone receptors’ estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) in tumors define the prognosis of the cancer and treatment options. Hence, clinically, breast cancers are defined as ER+/PR+, HER+, or triple-negative (i.e., those lacking expression of these three receptors). This classification system allows for the administration of endocrine therapies in the hormone expressing subtypes. Additionally, breast cancer subtyping is observed via transcriptome profiling, which has identified four major subtypes (luminal A, luminal B, HER2, and basal-like). The ER+/PR+ breast cancers are predominately luminal A/B and TNBCs are predominately basal-like. Clearly gene expression defines breast cancer; it is then not surprising that the expression of miRNAs also displays subtype-specificity.

Signal-Amplification Strategies for PAD
Paper-based analytical devices (PADs) have emerged as a promising approach to point-of-care (POC) detection applications in biomedical and clinical diagnosis owing to their advantages, including cost-effectiveness, ease of use, and rapid responses as well as for being equipment-free, disposable, and user-friendly. Total signal-amplification strategies in PADs involving colorimetry, luminescence, surface-enhanced Raman scattering, photoacoustic, photothermal, and photoelectrochemical methods as well as nucleic acid-mediated PAD modifications.

Applications of Graphene in Biosensors for Cancer Detection
Biosensors are a very promising tool for the possibility of sensitive, specific, and non-invasive diagnosis for early detection of cancer. Effective, accurate methods of cancer detection and clinical diagnosis are urgently needed. Biosensors are devices that are designed to detect a specific biological analyte by essentially converting a biological entity (i.e., protein, DNA, RNA) into an electrical signal that can be detected and analyzed. The ultimate goal of biosensors is to detect signals specific to each disease and cancer, and recently nanoparticles have been widely used in the design of biosensors. Graphene and its derivatives are nanoparticles with unique properties and have many applications in nanobiosensors.

Angiotensin-Converting Enzyme 2
The interaction between the membrane spike (S) protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the transmembrane angiotensin-converting enzyme 2 (ACE2) receptor of the human epithelial host cell is the first step of infection, which has a critical role for viral pathogenesis of the current coronavirus disease-2019 (COVID-19) pandemic.

PH Value in Clinically Diagnosis
As a highly influential physiological factor, pH may be leveraged as a tool to diagnose physiological state. It may be especially suitable for diagnosing and assessing skin structure and wound status. Multiple innovative and elegant smart wound dressings combined with either pH sensors or drug control-released carriers have been extensively studied. Increasing our understanding of the role of pH value in clinically relevant diagnostics should assist clinicians and improve personal health management in the home. In this review, we summarized a number of articles and discussed the role of pH on the skin surface as well as the factors that influence skin pH and pH-relevant skin diseases, but also the relationship of skin pH to the wound healing process, including its influence on the activity of proteases, bacterial enterotoxin, and some antibacterial agents.

Post-Harvest Operations to Generate High-Quality Medicinal Cannabis Products
Cannabis has been a traditional medicinal herb in central Asia, with reports of such usage back to 4700 B.P. in China, India, Persia, Egypt, Greece and Rome. It is now also cultivated and used as a drug crop in at least 172 countries and territories worldwide. It is classified as Cannabis Sativa, C. Indica and C. Ruderalis based on genetics, phenotypic properties and chemical structure. The Cannabis industry is rapidly growing; therefore, there is no medicinal cannabis that can be produced without optimising drying methods. Producing high-quality medical products have been a hot topic in recent years.

Biosensing Technologies for SARS-CoV-2
COVID-19 viral disease is officially global pandemic, currently accounting for the highest number of deaths worldwide. Special screening is extremely important as an effective way to monitor and manage the pandemic before reaching herb immunity through effective vaccination against SARS-CoV-2. A rapid population control task for COVID-19 has been documented using innovative methods in biosensor development. Biosensors are selected as promising detection devices with enormous potential as point-of-care (POC) tools to confirm the SARS-CoV-2 infection. Timely testing also helps to effectively allocate medical resources and save time for frontline medical staff. Hence, simple, rapid, cost-effective, and accessible detection techniques as POC diagnostics for large-scale screening and field testing of SARS-CoV-2 infection is important and should urgently be expedited to control the rapid and contagious spread of COVID-19.

CRISPR-Powered Microfluidics Applications
Clustered regularly interspaced short palindromic repeats (CRISPR) technology is a simple yet powerful tool for highly specific and rapid modification of DNA in a genome, which is the complete set of genetic instructions in an organism. One of the requirements for successful modification of the eukaryotic genome using the CRISPR/Cas9 system is the presence of the guide RNA (sgRNA or crRNA/duplex crRNA/tracrRNA) Cas9 protein complex and the introduction of mRNA or DNA. In therapeutic approaches, the genome of specific cells can be re-transplanted into the patient in vitro and then the host genome modified to treat any possible deficiency in genes. Nowadays, the use of microfluidic channels and chips is one of the best approaches to deliver materials and cells as it prevents many problems by accurately editing the cell and creating an opportunity for successful editing and screening of their genome. Such chips provide a suitable substrate for cell manipulation, drug screening, and exosome characterization. Furthermore, they are useful for pathogen and cancer detection because of their high throughput, low cost, flexibility, and controlled fluid or gas flow.

Adult Abdominal Tuberculosis Diagnosis
Tuberculosis is a common systemic infection with the bacteria Mycobacterium tuberculosis, which is primarily found in the lungs and causes caseous inflammation in lung tissue and other organs. Tuberculosis is an infectious disease that spreads via the air. Tuberculosis is an endemic disease in developing countries, due to the wide spread of acquired immunodeficiency syndrome (AIDS), it might represent a problem in developed countries, as well. Only around one-fifth of patients diagnosed with abdominal TB have pulmonary disease.
