Abstract
How do people deal with events they cannot control? Religious beliefs and practices are common responses to uncontrollable situations. We analyzed the responses of Singaporeans surveyed between November 2019 and March 2020-just before and just after Covid-19 hit the region-to understand how the beliefs and actions of both religious and non-religious people were affected by the emergence of the previously unknown virus. We find that after the emergence of Covid-19, religious respondents reported significantly higher levels of belief and service attendance frequency, while prayer frequency was not affected. We argue that the decrease in perceived controllability over people's lives explains these results. We discuss the implications of our findings for understanding the dynamics of religious beliefs and practices during times of uncertainty.

Abstract
The spindle tree (Euonymus europaeus L.) is a much-branched deciduous shrub or small tree. Its fruit capsules contain seeds with remarkably high content of oil interesting for industry, especially the 3-acetyl-1,2-diacyl-sn-glycerols (AcDAG) synthesized by a specific acetyl-CoA diacylglycerol acetyltransferase. The distribution and amount of individual triacylglycerols (TAG) and especially acetyl-triacylglycerols (AcDAG) in Euonymus fruit have previously been assigned to specific tissues. Using anatomical and microscopical observations, we studied the fruit morphology, and for the first time, we identified a more detailed allocation of oil bodies in individual tissue structures. Thin layer chromatography separation of extracts from immature and mature fruits confirmed TAG and AcDAG as the most abundant lipid classes in both endosperm and embryo, followed by fatty acids and polar lipids. The abundance of fatty acids was further studied in the TAG and AcDAG fractions using gas chromatography. Data revealed particular FAs in both fractions allocated in tissue-specific manner and/or as indicators of maturation of E. europaeus seeds. While the abundance of cis-vaccenic-, linoleic as well as α-linolenic acids in the AcDAG structures generally drop with maturation in both embryo and endosperm, content of oleic acid increases. Abundance of cis-vaccenic acid in TAG was recorded in immature endosperm. For embryo, the abundance of stearic acid in AcDAG and oleic acid in TAG fraction was distinctive. Deeper understanding of underlying metabolic processes will be essential for targeted metabolic engineering and/or application for oilseed crops.

Abstract
Hemodynamic and respiratory changes were studied during embolization of the pulmonary arterial bed in 20 rabbits after pentobarbital anesthesia. Air was insufflated into the auricular vein in the amount necessary to induce circulatory and respiratory changes. Circulatory changes were manifested by decreased arterial blood pressure, increased blood pressure in the right atrium, and aortal and pulmonary blood flow reduced to zero. The respiratory rate was diminished. A series of deep inspirations was followed by apnoe and death of the animal. (Fig. 5, Ref. 9.)
