Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Optimal Design of Planar Paraller Manipulators 3 RRR Through Lower Energy Consumption [PDF]

open access: yes, 2009
Organised by: Cranfield UniversityIn most existing studies, the solutions of planar parallel manipulators are restricted to a feasible region of solution. This research provides an optimal solution in link dimension of planar parallel manipulators to a

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Reconfiguration analysis of a 3-DOF parallel mechanism using Euler parameter quaternions and algebraic geometry method [PDF]

open access: yes, 2014
This paper deals with the reconfiguration analysis of a 3-DOF (degrees-of-freedom) parallel mechanism (PM) with multiple operation modes - a disassembly-free reconfigurable PM - using the Euler parameter quaternions and algebraic geometry approach.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

A novel 4-DOF parallel manipulator and its kinematic modelling [PDF]

open access: yes, 2001
In this paper a novel four-degree-of-freedom (4-DOF) hybrid parallel platform manipulator is presented. The movable platform of the parallel manipulator can translate along two directions and rotate around two axes respectively.

A comparison of the yaw constraining performance of SCARA-tau parallel manipulator variants via screw theory [PDF]

open access: yes, 2016
The SCARA-Tau parallel manipulator was derived with the objective to overcome the limited workspace-to-footprint ratio of the DELTA parallel manipulator while maintaining its many benefits.
