On Factorization of Integers with Restrictions on the Exponents
, 2007 For a fixed k ∈ N we consider a multiplicative basis in N such that every n ∈ N has the unique factorization as product of elements from the basis with the exponents not exceeding k. We introduce the notion of k-multiplicativity of arithmetic functions, and study several arithmetic functions naturally defined in k-arithmetics.

The design of artificial retroviral restriction factors
Virology, 2007 In addition to the ability to bind the retroviral capsid protein, the retroviral restriction factors Fv1, Trim5alpha and Trim5-CypA share the common property of containing sequences that promote self-association. Otherwise Fv1 and Trim5alpha appear unrelated.

Host Cell Restriction Factors that Limit Influenza A Infection
Viruses, 2017 Viral infection of different cell types induces a unique spectrum of host defence genes, including interferon-stimulated genes (ISGs) and genes encoding other proteins with antiviral potential.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.

R Factor-Controlled Restriction and Modification of Deoxyribonucleic Acid: Restriction Mutants [PDF]
Journal of Bacteriology, 1972 Restriction mutants of two different R factor-controlled host specificities (RI and RII) were isolated. All of the restriction mutants examined had a normal modification phenotype. No complementation was observed between the RI and RII host specificities.

Mannose Receptor 1 Restricts HIV Particle Release from Infected Macrophages
Cell Reports, 2018 Human mannose receptor 1 (hMRC1) is expressed on the surface of most tissue macrophages, dendritic cells, and select lymphatic or liver endothelial cells. HMRC1 contributes to the binding of HIV-1 to monocyte-derived macrophages (MDMs) and is involved in

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

Restriction Factors Against Human CMV
Future Virology, 2014 Cellular proteins called 'restriction factors' (RFs) form an important component of the innate immune response to viral replication. However, viruses have learned how to antagonize RFs through mechanisms that are specific for each virus. Here, we summarize the general hallmarks of RFs before going on to discuss the specific strategies recruited by some

Mouse APOBEC3 Restriction of Retroviruses
Viruses, 2020 Apolipoprotein B mRNA editing enzyme, catalytic peptide 3 (APOBEC3) proteins are critical host proteins that counteract and prevent the replication of retroviruses.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...
