Effect of Macrophages and Latent Reservoirs on the Dynamics of HTLV-I and HIV-1 Coinfection

Mathematics, 2023
Human immunodeficiency virus type 1 (HIV-1) and human T-lymphotropic virus type I (HTLV-I) are two retroviruses that have a similar fashion of transmission via sharp objects contaminated by viruses, transplant surgery, transfusion, and sexual relations ...

Molecular Methods for Rare Hemoglobinopathy Cases: First Brazilian Report of Pediatric Siblings with Hb O‐Arab and Alpha‐Thalassemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Hemoglobinopathies are prevalent globally; diagnosis is complex in high genetic admixture populations like Brazil. We report, in two pediatric siblings, the first documented cases in Brazil of heterozygosity for hemoglobin (Hb) O‐Arab with coinheritance of α‐thalassemia (αα/−α4.2; −α3.7/−α4.2), resulting in microcytic and hypochromic anemia ...

Global Properties of a Delay-Distributed HIV Dynamics Model Including Impairment of B-Cell Functions

Mathematics, 2019
In this paper, we construct an Human immunodeficiency virus (HIV) dynamics model with impairment of B-cell functions and the general incidence rate. We incorporate three types of infected cells, (i) latently-infected cells, which contain the virus, but ...

Global imbalances and financial stability [PDF]

Journal of Policy Modeling, 2007
Abstract There are two opposing views on global imbalances: The “traditional” view, which regards the imbalances as a threat to global economic and financial stability, and the “new paradigm” view, which considers that they are the natural consequence of economic and financial globalization. In terms of their policy implications, the traditional view

Effects of soil fertility and toxicity on the performance of Chenopodium quinoa (Willd) plants in kin and non-kin interactions

Plant Signaling & Behavior
Kin selection theory predicts that closely related organisms may exhibit cooperative behaviors that enhance group fitness despite individual costs. In contrast, the resource partitioning hypothesis posits stronger competition among close relatives due to

Mathematical Model to Study the Effect of Refuge on Cannibalism in Atractosteus tropicus

Mathematics
Cannibalism is a behavior that different species of fish exhibit in the early stages of their life, and it has been widely reported. In Tabasco, Mexico, the ancestral species Atractosteus tropicus is farmed, which is a freshwater fish with a high ...

The Efficacy and Safety of Bevacizumab/Irinotecan/Temozolomide (BIT) for Relapsed/Refractory Neuroblastoma: The UK Children's Cancer and Leukaemia Group Experience

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Patients with high‐risk neuroblastoma who either are refractory to induction chemotherapy or relapse following multi‐modal treatment have a dismal prognosis. Based on data from the BEACON trial, since 2021 the UK national guidelines recommend bevacizumab, irinotecan, and temozolomide (BIT) for patients with relapsed/refractory ...

Upacicalcet: A Novel Intravenous Calcimimetic Agent for Patients Undergoing Hemodialysis With Secondary Hyperparathyroidism

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving maintenance dialysis, driven by calcium and phosphate metabolism disturbances. Calcimimetics are central to the management of SHPT by enhancing calcium‐sensing receptor sensitivity and reducing parathyroid hormone secretion.
