Earthquakes, Volcanoes and God: Comparative Perspectives from Christianity and Islam

This paper asserts that both Christian and Islamic traditions of faith affect the ways in which people both try to make sense of, and respond to, disasters. This contention is supported by the results of empirical research, which demonstrates that differing Islamic and Christian perspectives on human suffering caused by disasters are neither as diverse, nor are they so intractable, as is commonly supposed. Today pastoral convergence between the two traditions may also be discerned, together with a general acceptance of the policies of both State agencies and Non-Governmental Organisations (NGOs) which are concerned with hazard relief and the propagation of policies of disaster risk reduction (DRR). Indeed some important disaster relief NGOs have emerged from Islamic and Christian faith communities and are supported by charitable donations

Cosmological Visions, Multispecies Practices, and Planetary Health in Pandemic Times

The cosmovisions of the so-called world religions are based on assumed divides between nature and culture, nonhuman and human, man and God, and these divisions have long been reproduced by the social sciences. Only recently, a radical interrelatedness has been thematized and acknowledged by certain scholars, and indeed, the current pandemic reminds us of zoonoses and the manifold relationships that humans have with other forms of life. At the same time, local or folk religions offer alternative ontologies including transgressions between humans and animals or spirits. Thus, they indicate that there is no “above” or “outside of” nature. Perhaps future multispecies practices will be shaped by a new awareness of such relatedness and symbiosis, as offered by the Planetary Health approach: a relational health concept that will prepare for future challenges by focusing on the interrelationships between human health, political, economic, and social contexts as well as the biodiversity of our planet

Mitophagy of damaged mitochondria occurs locally in distal neuronal axons and requires PINK1 and Parkin

To minimize oxidative damage to the cell, malfunctioning mitochondria need to be removed by mitophagy. In neuronal axons, mitochondrial damage may occur in distal regions, far from the soma where most lysosomal degradation is thought to occur. In this paper, we report that PINK1 and Parkin, two Parkinson’s disease–associated proteins, mediate local mitophagy of dysfunctional mitochondria in neuronal axons. To reduce cytotoxicity and mimic physiological levels of mitochondrial damage, we selectively damaged a subset of mitochondria in hippocampal axons. Parkin was rapidly recruited to damaged mitochondria in axons followed by formation of LC3-positive autophagosomes and LAMP1-positive lysosomes. In PINK1−/− axons, damaged mitochondria did not accumulate Parkin and failed to be engulfed in autophagosomes. Similarly, initiation of mitophagy was blocked in Parkin−/− axons. Our findings demonstrate that the PINK1–Parkin-mediated pathway is required for local mitophagy in distal axons in response to focal damage. Local mitophagy likely provides rapid neuroprotection against oxidative stress without a requirement for retrograde transport to the soma

A genetic variant in the pre-miR-27a oncogene is associated with a reduced familial breast cancer risk

MicroRNAs (miRNAs) regulate pathways involved in cell differentiation, proliferation, development, and apoptosis by degradation of target mRNAs and/or repression of their translation. Although the single nucleotide polymorphisms (SNPs) in miRNAs target sites have been studied, the effects of SNPs in miRNAs are largely unknown. In our study, we first systematically sequenced miRNA genes reported to be involved in breast cancer to identify/verify SNPs. We analyzed four SNPs, one located in the pre-miRNA and the other three located in miRNA flanking regions, for a putative association with breast cancer risk. The SNP rs895819, located in the terminal loop of pre-miRNA-27a, showed a protective effect. In a large familial breast cancer study cohort, the rare [G] allele of rs895819 was found to be less frequent in the cases than in the controls, indicating a reduced familial breast cancer risk ([G] vs. [A]: OR = 0.88, 95% CI 0.78–0.99, P = 0.0287). Furthermore, age stratification revealed that the protective effect was mainly observed in the age group < 50 years of age ([G] vs. [A]: OR = 0.83, 95% CI 0.70–0.98, P = 0.0314), whereas no significant effect was observed in the age group ≥ 50 years of age, indicating a possible hormone-related effect. It has been shown that artificial mutations in the terminal loop of miR-27a can block the maturation process of the miRNA. We hypothesize that the G-variant of rs895819 might impair the maturation of the oncogenic miR-27a and thus, is associated with familial breast cancer risk

Identification of a DMBT1 polymorphism associated with increased breast cancer risk and decreased promoter activity

According to present estimations, the unfavorable combination of alleles with low penetrance but high prevalence in the population might account for the major part of hereditary breast cancer risk. Deleted in Malignant Brain Tumors 1 (DMBT1) has been proposed as a tumor suppressor for breast cancer and other cancer types. Genomewide mapping in mice further identified Dmbt1 as a potential modulator of breast cancer risk. Here, we report the association of two frequent and linked single-nucleotide polymorphisms (SNPs) with increased breast cancer risk in women above the age of 60 years: DMBT1 c.-93C>T, rs2981745, located in the DMBT1 promoter; and DMBT1 c.124A>C, p.Thr42Pro, rs11523871(odds ratio [OR]=1.66, 95% confidence interval [CI]=1.21-2.29, P=0.0017; and OR=1.66; 95% CI=1.21-2.28, P=0.0016, respectively), based on 1,195 BRCA1/2 mutation-negative German breast cancer families and 1,466 unrelated German controls. Promoter studies in breast cancer cells demonstrate that the risk-increasing DMBT1 -93T allele displays significantly decreased promoter activity compared to the DMBT1 -93C allele, resulting in a loss of promoter activity. The data suggest that DMBT1 polymorphisms in the 5'-region are associated with increased breast cancer risk. In accordance with previous results, these data link decreased DMBT1 levels to breast cancer risk
