Methods women use for induced abortion and sources of services: insights from poor urban settlements of Accra, Ghana

open access: yesBMC Women's Health, 2021
Background Increasing access to safe abortion methods is crucial for improving women’s health. Understanding patterns of service use is important for identifying areas for improvement. Limited evidence is available in Ghana on factors associated with the

Membrane fusion mediated by ricin and viscumin [PDF]

open access: yes, 1998
The ribosome inactivating plant proteins (RIPs) ricin and viscumin but not Ricinus communis agglutinin are able induce vesicle–vesicle fusion. A model is suggested in which the toxicity of the RIPs is partially determined by their fusogenicity.

Genetic Diversity and Population Structures in Chinese Miniature Pigs Revealed by SINE Retrotransposon Insertion Polymorphisms, a New Type of Genetic Markers

open access: yesAnimals, 2021
RIPs have been developed as effective genetic markers and popularly applied for genetic analysis in plants, but few reports are available for domestic animals.

SimBa: An Efficient Tool for Approximating Rips-Filtration Persistence via Simplicial Batch-Collapse [PDF]

open access: yes, 2016
In topological data analysis, a point cloud data P extracted from a metric space is often analyzed by computing the persistence diagram or barcodes of a sequence of Rips complexes built on P indexed by a scale parameter.

Persistence stability for geometric complexes [PDF]

open access: yes, 2013
In this paper we study the properties of the homology of different geometric filtered complexes (such as Vietoris-Rips, Cech and witness complexes) built on top of precompact spaces.

Argumentative Thinking: An Introduction to the Special Issue on Psychology and Argumentation

open access: yesInformal Logic, 2009
This special issue of Informal Logic brings together a num-ber of traditions from the psychology and philosophy of argument. Psycho-logists’ interest in argument typically arises in understanding how indivi-duals form and change their beliefs.

Structure and Biological Properties of Ribosome-Inactivating Proteins and Lectins from Elder (Sambucus nigra L.) Leaves

open access: yesToxins, 2022
Ribosome-inactivating proteins (RIPs) are a group of proteins with rRNA N-glycosylase activity that catalyze the removal of a specific adenine located in the sarcin–ricin loop of the large ribosomal RNA, which leads to the irreversible inhibition of ...

The Vietoris-Rips complexes of a circle

open access: yes, 2017
Given a metric space X and a distance threshold r>0, the Vietoris-Rips simplicial complex has as its simplices the finite subsets of X of diameter less than r.

Sapovaccarin-S1 and -S2, Two Type I RIP Isoforms from the Seeds of Saponaria vaccaria L.

open access: yesToxins, 2022
Type I ribosome-inactivating proteins (RIPs) are plant toxins that inhibit protein synthesis by exerting rRNA N-glycosylase activity (EC 3.2.2.22). Due to the lack of a cell-binding domain, type I RIPs are not target cell-specific. However once linked to
