Biofluids: Storage of Biomarkers
In recent years, there has been an increase in knowledge of cancer, accompanied by a technological development that gives rise to medical oncology. An instrument that allows the implementation of individualized therapeutic strategies is the liquid biopsy. Currently, it is the most innovative methodology in medical oncology. Its high potential as a tool for screening and early detection, the possibility of assessing the patient’s condition after diagnosis and relapse, as well as the effectiveness of real-time treatments in different types of cancer. Liquid biopsy is capable of overcoming the limitations of tissue biopsies. The elements that compose the liquid biopsy are circulating tumor cells, circulating tumor nucleic acids, free of cells or contained in exosomes, microvesicle and platelets. Liquid biopsy studies are performed on various biofluids extracted in a non-invasive way, and they can be performed both from the blood and in urine, saliva or cerebrospinal fluid. The development of genotyping techniques, using the elements that make up liquid biopsy, make it possible to detect mutations, intertumoral and intratumoral heterogeneity, and provide molecular information on cancer for application in medical oncology in an individualized way in different types of tumors. Therefore, liquid biopsy has the potential to change the way medical oncology could predict the course of the disease.

Urinary Biomarkers for Bladder Cancer
Blue light cystoscopy (BLC) is the most recent clinical approach in the detection and diagnosis of bladder cancer, a common type of cancer with a high rate of recurrence. Representing a significant advance over previous approaches, this photodynamic diagnostic technique uses a photosensitiser prodrug as an adjunct to white light cystoscopy to enhance the in vivo detection of malignant tissues in the bladder based on their distinctive fluorescence. Whilst it does improve detection rates, BLC remains an invasive and costly procedure. Meanwhile, a variety of noninvasive urine detection methods and related microdevices have been developed.  In the following section, we provide the current context for urinary biomarker testing, including commercially available tests and recent development involving microdevices.

Ferroptosis in Liver Diseases
Ferroptosis is an iron-dependent form of cell death characterized by intracellular lipid peroxide accumulation and redox imbalance. Ferroptosis shows specific biological and morphological features when compared to the other cell death patterns. The loss of lipid peroxide repair activity by glutathione peroxidase 4 (GPX4), the presence of redox-active iron and the oxidation of polyunsaturated fatty acid (PUFA)-containing phospholipids are considered as distinct fingerprints of ferroptosis. Several pathways, including amino acid and iron metabolism, ferritinophagy, cell adhesion, p53, Keap1/Nrf2 and phospholipid biosynthesis, can modify susceptibility to ferroptosis. Through the decades, various diseases, including acute kidney injury; cancer; ischemia-reperfusion injury; and cardiovascular, neurodegenerative and hepatic disorders, have been associated with ferroptosis. Here, we provide a short overview of the main biological and biochemical mechanisms of ferroptosis. The contribution of ferroptosis to the spectrum of liver diseases, acute or chronic is also reported. Finally, we discuss the use of ferroptosis as a therapeutic approach against hepatocellular carcinoma, the most common form of primary liver cancer.

Chondrocytes
Chondrocytes are the cells found in cartilage that responsible for the production and maintenance of the cartilaginous matrix, which consists of collagen, proteoglycans, glycoproteins and hyaluronan. Autologous chondrocyte implantation (ACI) is a new treatment modality with the potential to promote regeneration of worn cartilage. ACI has been used to treat osteoarthritis (OA), a degenerative joint disease that affects many people worldwide. Human platelet lysate (HPL) has been identified as a potential replacement for foetal bovine serum (FBS) for the expansion of chondrocytes.

Auditory neurons in inner ear
These neurons transmit auditory information in the form of electric signals from sensory hair cells to the first auditory nuclei of the brain stem, the cochlear nuclei. Congenital and acquired neurosensory hearing loss affects millions of people worldwide. An increasing body of evidence suggest that the primary auditory neurons degenerate due to noise exposure and aging more readily than sensory cells, and thus, auditory neurons are a primary target for regenerative therapy. A better understanding of the development and function of these neurons is the ultimate goal for long-term maintenance, regeneration, and stem cell re-placement therapy.

Allergy and Allergic Diseases Prevention
Prophylactic interventions for the prevention of allergic diseases differ depending on the timing and the stage in the ontogeny of the processes leading from sensitisation to clinical symptoms.  They can be divided into primary, secondary and tertiary prophylaxis.

Porphyromonas Gingivalis and Systemic Diseases
The relationship between periodontitis and systemic diseases, notably including atherosclerosis and diabetes, has been studied for several years. Porphyromonas gingivalis, a prominent component of oral microorganism communities, is the main pathogen that causes periodontitis. We comprehensively summarize the adverse effects of Porphyromonas gingivalis on multiple systems and a variety of diseases, from extensively studied fields (cardiovascular diseases, cancer, adverse pregnancy outcomes, etc.) to emerging areas (Alzheimer's Disease, nonalcoholic fatty liver disease, depression, etc.). Although a few results remain controversial, it is now evident that Porphyromonas gingivalis should be regarded as a modifiable factor for several diseases.

Blood Neurofilament Light Chain
Neurofilament light chain (NfL) is a neuron specific structural protein which can be detected in the blood (serum and plasma). Elevate blood levels may serve as an important surrogate neuro-axonal injury in a variety of neurological conditions, already showing promising associations with outcomes of interest.

COVID-19 Treatment
The novel coronavirus disease (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has engulfed the world, affecting more than 180 countries. As a result, there has been considerable economic distress globally and a significant loss of life. Sadly, the vulnerable and immunocompromised in our societies seem to be more susceptible to severe COVID-19 complications. Notably, there are several significant risk factors for severe COVID-19 infection. These include the presence of poor nutritional status and pre-existing noncommunicable diseases (NCDs) such as diabetes mellitus, chronic lung diseases, cardiovascular diseases (CVD), obesity, and various other diseases that render the patient immunocompromised. These diseases are characterized by systemic inflammation, which may be a common feature of these NCDs, affecting patient outcomes against COVID-19. As a result, various antiviral treatments and anti-inflammatory agents are under investigation for their potential therapeutic value. The section presented below originates from the following article [1].
