Phage Display Technology in Monoclonal Antibody Production
The groundbreaking work of John McCafferty and Sir Gregory Winter in developing phage display technology revolutionized the discovery of human antibodies, paving the way for diverse applications. Since then, numerous phage-derived antibodies have been successfully developed and advanced into clinical studies, resulting in the approval of more than a dozen therapeutic antibodies. These antibodies have demonstrated efficacy across a spectrum of medical conditions, ranging from autoimmune diseases to various cancers.

Laboratory Tools to Predict CFTR Modulator Effectiveness
The implementation of cystic fibrosis (CF) transmembrane conductance regulator (CFTR) modulator drugs into clinical practice has been attaining remarkable therapeutic outcomes for CF, a life-threatening autosomal recessive genetic disease. However, there is elevated CFTR allelic heterogeneity, and various individuals carrying (ultra)rare CF genotypes remain without any approved modulator therapy. Novel translational model systems based on individuals’ own cells/tissue are now available and can be used to interrogate in vitro CFTR modulator responses and establish correlations of these assessments with clinical features, aiming to provide prediction of therapeutic effectiveness.

Molybdenum Disulfide Biosensor for Cancer Biomarker Detection
Molybdenum disulfide (MoS2) is a promising two-dimensional (2D) nanomaterial, whose unique adjustable bandgap shows excellent electronic and optical properties in the construction of biosensor interfaces. It not only has the advantages of a high catalytic activity and low manufacturing costs, but it can also further expand the application of hybrid structures through different functionalization, and it is widely used in various biosensors fields.

Neuroprotective Effects of Polyphenols in Neurodegenerative Diseases
It has been shown that polyphenols in various natural sources can provide curative effects against various brain diseases and disorders through neuroprotective effects. These neuroprotective effects are mainly attributed to its ability to cross the blood-brain barrier, remove reactive oxygen species, and cause chelation of metal ions. Polyphenols increase the concentration of neurotrophic factors and bind directly to the membrane receptors of these neurotrophic factors to modulate and activate the signaling cascades that allow the plasticity, survival, proliferation, and growth of neuronal cells, allowing better learning, memory, and cognition. Furthermore, polyphenols do not have serious adverse side effects from their consumption.

Preparation and Purification of In Vitro-Transcribed-mRNA-Based Molecules
The Corona Virus Disease 2019 (COVID-19) pandemic poses a disruptive impact on public health and the global economy. Fortunately, the development of COVID-19 vaccines based on in vitro transcribed messenger RNA (IVT mRNA) has been a breakthrough in medical history, benefiting billions of people with its high effectiveness, safety profile, and ease of large-scale production. This success is the result of decades of continuous RNA research, which has led to significant improvements in the stability and expression level of IVT mRNA through various approaches such as sequence optimization and improved preparation processes. IVT mRNA sequence optimization has been shown to have a positive effect on enhancing mRNA expression level. The innovation of IVT mRNA purification technology is also indispensable, as the purity of IVT mRNA directly affects success of downstream vaccine preparation processes and the potential for inducing unwanted side effects in therapeutic applications. Despite the progress made, challenges related to IVT mRNA sequence design and purification still require further attention to enhance the quality of IVT mRNA in the future.

Immunosensors for Autoimmune-Disease-Related Biomarkers
Autoimmune diseases (ADs) are a group of various disorders that are characterized by dysregulation of the immune system. This malfunction state leads to an improper activation of immune elements that may consequently attack target molecules, cells, and tissues of the organism, resulting in inflammation and organ damage. Due to the continuously increasing number of patients with ADs, the severity of ADs’ clinical symptoms, and treatment insufficiency, novel analytical tools enabling early, reliable, and high-throughput disease diagnosis are highly desirable, since such tools may help health systems to confront the burden related to the late diagnosis of ADs and decrease premature mortality. To meet this need, during the last two decades, several immunosensors for detecting AD-related biomarkers have been developed as research prototypes. The AD immunosensors reported to date can be divided into two main categories depending on the biomarker(s) detected, i.e., either various autoantibodies or other protein biomarkers, such as specific inflammation-related cytokines. Most of AD immunosensors are electrochemical, while some optical and a few piezoelectric sensors have also been described.

Patient-Derived Cancer Models and Next-Generation Living Biobanks
Biobanks provide a platform for innovative biomedical research. Recent scientific advances in cryopreservation have enabled the prospect of establishing “living biobanks” that store viable, functional tissue or replicable cell types for years to decades.

Causes of Hypermagnesemia
Hypermagnesemia is a relatively uncommon but potentially life-threatening electrolyte disturbance characterized by elevated magnesium concentrations in the blood. Magnesium is a crucial mineral involved in various physiological functions, such as neuromuscular conduction, cardiac excitability, vasomotor tone, insulin metabolism, and muscular contraction. Prompt identification and management of hypermagnesemia are crucial to prevent complications, such as respiratory and cardiovascular negative outcomes, neuromuscular dysfunction, and coma. Preventing hypermagnesemia is crucial, particularly in high-risk populations, such as patients with impaired renal function or those receiving magnesium-containing medications or supplements.

Uric Acid Electroanalysis
Uric acid is a metabolic product that results from degradation of purines in the liver. Usually, uric acid is identified from biological fluids, human serum and urine through conventional methods, such as spectroscopy, chromatography, electrochemistry, membrane capillary electrophoresis and spectrophotometric methods, including uricase enzymatic reactions. Importantly, uric acid determination opens the possibility of early intervention in cases of hyperuricemia and preventing the degradation of renal function.

Therapeutic Drug Monitoring of Beta-Lactam Antibiotics
Here describes various aspects of beta-lactams use in the critical care, focusing on clinical antibiotic stewardship in the ICU. Pharmacokinetics / pharmacodynamics (PK/PD) characteristics of beta-lactams are described and main factors of PK/PD variability in critically ill patients. Toxicity of beta-lactams, a frequently overlooked issue, is outlined. Analytical methods used in therapeutic drug monitoring (TDM) of beta-lactams are discussed. The evidence supporting antibiotic guidance based on therapeutic drug monitoring (TDM) in critically ill patients is analysed.
