Objectives: This single-centre prospective randomised controlled study aimed to investigate the effectiveness of dignity therapy on spiritual well-being, demoralisation and dignity-related distress compared with standard palliative care.

Methods: A total of 111 terminally ill hospice patients were randomly allocated to one of two groups: dignity therapy plus standard palliative care (intervention group) or standard palliative care alone (control group). The main outcomes were meaning, peace, faith, loss of meaning and purpose, distress and coping ability, existential distress, psychological distress and physical distress.

Dignity Therapy (DT) is a brief, individualized, narrative psychotherapy developed to reduce psychosocial and existential distress, and promote dignity, meaning, and hope in end of life patients. Previous studies have shown that DT was effective in reducing anxiety and depression, and improving dignity-related distress. However, less is known about its efficacy on spiritual well-being.

RrS1-like sequences of water frogs (genus Pelophylax) display varied genomic organization, whereas the centromeric hybridization pattern reveals species-specific differences. Using fluorescent in situ hybridization, Pelophylax cf. bedriagae, Pelophylax kurtmuelleri, and Pelophylax ridibundus showed a hybridization signal at centromeres of chromosomes 1-5, but in P.

In many organisms, the specification of cell fate and the formation of embryonic axes depend on a proper distribution of maternal mRNAs during oogenesis. Asymmetrically localized determinants are required both for embryonic axes and germline determination in anuran amphibians. As a model system of these processes, we have used a species complex of the genus Pelophylax (Rana), characterized by a hybridogenetic reproduction that involves events of genome exclusion and endoreduplication during meiosis in both sexes.

Cadmium, a toxic environmental contaminant, exerts adverse effects on different cellular pathways such as cell proliferation, DNA damage and apoptosis. In particular, the modulation of Ca(2+) homeostasis seems to have an important role during Cd(2+) injury, but the precise assessment of Ca(2+) signalling still remains poorly understood. We used aequorin-based probes specifically directed to intracellular organelles to study Ca(2+) changes during cadmium injury.

European water frog hybrids Rana esculenta (R. ridibundaxR. lessonae) reproduce hemiclonally, by hybridogenesis: in the germ line they exclude the genome of one parental species and produce haploid gametes with an unrecombined genome of the other parental species.

Germline cell fate decisions are primarily controlled at the post-transcriptional level with DEAD-box RNA helicases playing a crucial role in germline development. In this study, we report the identification of two DEAD-box vasa/PL10 orthologues (RlVlg and RlPL10) in a species complex of the genus Rana, characterized by hybridogenetic reproduction, an enigmatic process that involves the exclusion of an individual genome, and endoreduplication events. Both genes were expressed during the early stages of gametogenesis of R.
