Acute Myeloid Leukemia Stem Cells
Relapse after apparent remission remains a major cause of death in patients with acute myeloid leukemia (AML). On the cellular level, leukemia relapse is considered to emerge from subpopulations of therapy-resistant leukemic stem cells (LSC). Identification and targeting of LSC are thus most important goals for AML treatment. However, AML and their LSC are highly heterogeneous.

Protamine-Based Strategies for RNA Transfection
Protamine is a natural cationic peptide mixture mostly known as a drug for the neutralization of heparin and as a compound in formulations of slow-release insulin. Protamine is also used for cellular delivery of nucleic acids due to opposite charge-driven coupling. This year marks 60 years since the first use of Protamine as a transfection enhancement agent. Since then, Protamine has been broadly used as a stabilization agent for RNA delivery. It has also been involved in several compositions for RNA-based vaccinations in clinical development. Protamine stabilization of RNA shows double functionality: it not only protects RNA from degradation within biological systems, but also enhances penetration into cells. A Protamine-based RNA delivery system is a flexible and versatile platform that can be adjusted according to therapeutic goals: fused with targeting antibodies for precise delivery, digested into a cell penetrating peptide for better transfection efficiency or not-covalently mixed with functional polymers.

Chronic Nightmare in Psychiatric Disorders
Chronic nightmares are very common in psychiatric disorders, affecting up to 70% of patients with personality or post-traumatic stress disorders. In other psychiatric disorders, the relationships with nightmares are poorly known. This review aimed to clarify the relationship between nightmares and both mood and psychotic disorders.

Nanotechnology-facilitated Bacterial Therapy
In recent years, advancing nanotechnology has extended bacterial therapies to a higher level through tailoring bacteria on a nanoscale, such as bacteria-derived nanovesicles and bacterial membrane-coated nanoparticles, or endowing bacteria with abilities to serve as drug carriers, photosensitizers, and sonosensitizers.

Muse Cells
Muse cells, identified as pluripotent surface marker, stage-specific embryonic antigen (SSEA)-3(+), are endogenous reparative pluripotent stem cells distributed in the bone marrow, peripheral blood and connective tissue of every organ. Since they are non-tumorigenic and do not require gene introduction or cytokine treatment to be rendered pluripotent and induce differentiation, they elicit few safety concerns. They can be delivered intravenously and do not require surgery for their administration since they selectively home to damaged site by sphingosine-1-phosphate (S1P)-S1PR2 axis after intravenous injection. Donor-Muse cells can be used without HLA-matching test or immunosuppressant treatment since they have a specific immunomodulatory system represented by HLA-G expression.

Smallpox Virus Retention Controversy
The smallpox virus retention controversy is a debate that has been ongoing among international scientists and other officials since smallpox was declared eradicated by the World Health Organization (WHO) in 1980. It centers on whether to finally and irreversibly destroy the two last remnants of the virus that causes smallpox, which reside in government laboratories in the United States and Russia . Advocates of final destruction maintain that there is no longer any valid rationale for retaining the samples, which represent a hazard, while opponents of it maintain that the samples are needed for further research as smallpox virus may still exist in the world outside of the two labs, and thus may re-emerge, particularly as a bio-weapon.

COVID-19: Neurological Considerations in Neonates/Children
The ongoing worldwide pandemic of the novel human coronavirus SARS-CoV-2 and the ensuing disease, COVID-19, has presented enormous and unprecedented challenges for all medical specialists. However, to date, children, especially neonates, have been relatively spared from the devastating consequences of this infection. Neurologic involvement is being increasingly recognized among adults with COVID-19, who can develop sensory deficits in smell and taste, delirium, encephalopathy, headaches, strokes, and peripheral nervous system disorders. Among neonates and children, COVID-19-associated neurological manifestations have been relatively rare, yet reports involving neurologic dysfunction in this age range are increasing.

Rosemary (Rosmarinus officinalis)
Rosemary (Rosmarinus officinalis [family Lamiaceae]), an herb of economic and gustatory repute, is employed in traditional medicines in many countries. Rosemary contains carnosic acid (CA) and carnosol (CS), abietane-type phenolic diterpenes, which account for most of its biological and pharmacological actions, although claims have also been made for contributions of another constituent, rosmarinic acid.
