Brain Iron Metabolism
Iron is an essential trace element important for many biological functions, including the essential functions of the nervous system. Understanding the mechanisms of iron homeostasis is  of clinical relevance since either depletion or accumulation of intracellular iron may affect the normal function of the cell. Brain iron metabolism is a topic of growing interest since numerous researches have proved its role in neurodegeneration (e.g. Alzheimer's disease, Parkinson's disease) and other neurological disorders, especially in elderly. Maintaining of brain iron homeostasis is very specific because of the blood-brain barrier. It is a physiological barrier formed by the endothelial cells that line cerebral microvessels and has an important role in maintaining a precisely regulated brain microenvironment. Despite the years of research, the complex mechanisms for the iron influx, efflux, and regulation in the brain are not completely resolved. It would be of great importance for the future research to determine the exact cellular and molecular mechanisms related to disturbances of brain iron metabolism, especially in the context of brain aging and as potential therapeutic targets for neurodegenerative diseases.

Catheter
In medicine, a catheter is a thin tube made from medical grade materials serving a broad range of functions. Catheters are medical devices that can be inserted in the body to treat diseases or perform a surgical procedure. By modifying the material or adjusting the way catheters are manufactured, it is possible to tailor catheters for cardiovascular, urological, gastrointestinal, neurovascular, and ophthalmic applications. Catheters can be inserted into a body cavity, duct, or vessel. Functionally, they allow drainage, administration of fluids or gases, access by surgical instruments, and also perform a wide variety of other tasks depending on the type of catheter. The process of inserting a catheter is "catheterization". In most uses, a catheter is a thin, flexible tube ("soft" catheter) though catheters are available in varying levels of stiffness depending on the application. A catheter left inside the body, either temporarily or permanently, may be referred to as an "indwelling catheter" (for example, a peripherally inserted central catheter). A permanently inserted catheter may be referred to as a "permcath" (originally a trademark).

Near-Haploidy and Low-Hypodiploidy in B-Cell Acute Lymphoblastic Leukemia
B-cell acute lymphoblastic leukemia (B-ALL) is characterized by an uncontrolled proliferation of blood cells in the bone marrow. Hypodiploidy with less than 40 chromosomes is a rare genetic abnormality in B-cell acute lymphoblastic leukemia (B-ALL). This condition can be classified based on modal chromosome number as low-hypodiploidy (30–39 chromosomes) and near-haploidy (24–29 chromosomes), with unique cytogenetic and mutational landscapes.

Morita Therapy
Morita therapy is an ecological, purpose-centered, response-oriented therapy created through case-based research by Shoma Morita, M.D. (1874–1938). Morita developed his theory of consciousness and medically-grounded four-stage progressive therapeutic method with rigor. The goal of Morita therapy is to have the patient accept life as it is. This does not mean that the patient cannot set and achieve goals, but be able to be satisfied with their life in the moment. Morita therapy places an emphasis on letting nature take its course. This is not to say that patients should be resigned to their mental illness but to respect the laws of nature. Feeling emotions is a law of nature according to Morita therapy. Morita therapy helps its patients understand that experiencing emotions, positive or negative, is a facet of being a human being. Morita describes his own therapy as follows: Morita therapy was originally developed to address shinkeishitsu, an outdated term used in Japan to describe patients who have various types of anxiety. Morita therapy was designed not to completely rid the patient of shinkeishitsu but to lessen the damaging effects. While Morita therapy has been described as cognate to Albert Ellis's rational-emotive therapy, this description does not account for the ecological foundation of the therapy. Morita therapy also has commonalities with existential and cognitive behavioral therapy.

Therapeutic Ophthalmic Lenses
The increase of public awareness on ocular conditions leads to an early diagnosis and treatment, as well as an increased demand for more effective and minimally invasive solutions for the treatment of both the anterior and posterior segments of the eye. Despite being the most common route of ophthalmic drug administration, eye drops are associated with compliance issues, drug wastage by lacrimation, and low bioavailability due to the ocular barriers. In order to overcome these problems, the design of drug-eluting ophthalmic lenses constitutes a non-invasive and patient-friendly approach for the sustained drug delivery to the eye. Several examples of therapeutic contact lenses and intraocular lenses have been developed, by means of different strategies of drug loading, leading to promising results.

Microneedle Array Technology in Nanomedicine
Organic and inorganic nanoparticles (NPs) have shown promising outcomes in transdermal drug delivery. NPs can not only enhance the skin penetration of small/biomacromolecule therapeutic agents but also can impart control over drug release or target impaired tissue. Thanks to their unique optical, photothermal, and superparamagnetic features, NPs have been also utilized for the treatment of skin disorders, imaging, and biosensing applications. Despite the widespread transdermal applications of NPs, their delivery across the stratum corneum, which is the main skin barrier, has remained challenging. Microneedle array (MN) technology has recently revealed promising outcomes in the delivery of various formulations, especially NPs to deliver both hydrophilic and hydrophobic therapeutic agents.

Coenzyme Q10 in Fibromyalgia
The coenzyme Q10 is a naturally occurring benzoquinone derivative widely prescribed as a food supplement for different physical conditions and pathologies. Thanks to its favourable combination of functional activity and safety profile, it is widely prescribed for an ever increasing number of physical conditions. Ageing, myopathy, cardiomyopathy, high blood pressure, dyslipidemia, migraine, diabetes, infertility, Friedreich's ataxia, and neurologic disorders like Parkinson’s and Huntington’s diseases, are but a few examples that today prompt practitioners to prescribe CoQ10. To this already extensive list, fibromyalgia has been added, once it has been clear that CoQ10 deficiency and mitochondrial dysfunction are both implicated in its pathophysiology.

Anti-Inflammatory Agents in Prostate Cancer
Chronic inflammation is a major cause of human cancers. The environmental factors, such as microbiome, dietary components, and obesity, provoke chronic inflammation in the prostate, which promotes cancer development and progression. Crosstalk between immune cells and cancer cells enhances the secretion of intercellular signaling molecules, such as cytokines and chemokines, thereby orchestrating the generation of inflammatory microenvironment. Tumor-associated macrophages (TAMs) and myeloid-derived suppressor cells (MDSCs) play pivotal roles in inflammation-associated cancer by inhibiting effective anti-tumor immunity. Anti-inflammatory agents, such as aspirin, metformin, and statins, have potential application in chemoprevention of prostate cancer. Furthermore, pro-inflammatory immunity-targeted therapies may provide novel strategies to treat patients with cancer. Thus, anti-inflammatory agents are expected to suppress the “vicious cycle” created by immune and cancer cells and inhibit cancer progression. This review has explored the immune cells that facilitate prostate cancer development and progression, with particular focus on the application of anti-inflammatory agents for both chemoprevention and therapeutic approach in prostate cancer.
