Thin Lenses and Thin Cameras

open access: yes, 2021
Cassegrain designs can be used to build thin lenses. We analyze the relationships between system thickness and aperture sizes of the two mirrors as well as FoV size. Our analysis shows that decrease in lens thickness imposes tight constraint on the aperture and FoV size.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

MESUROL – A FACTOR TOWARDS MORE REGULAR APPLE BEARING [PDF]

open access: yesPoljoprivreda, 2004
Chemical thinning of apple fruits 7.3 mm (cv. Gloster) and 9.3 mm (cv. Jonagold) in diameter was performed with Mesurol® WP 50 (concentration 1800 ppm).

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Optimum oil palm planting density in West Africa

open access: yesOilseeds and fats, crops and lipids, 2018
This article follows on from an earlier one about the same experiment in 2014. A range of various planting distances (from 7.5 to 9.5 metres) between oil palms was tested using an equilateral triangle design.

Accelerated formation of Siberian pine (Pinus sibirica Du Tour) stands: a case study from Siberia

open access: yesJournal of Forest Science, 2019
Under natural conditions, Siberian pine Pinus sibirica begins to produce commercial cone yields of nuts relatively late (after more than 100 years). The aim of this study was to summarise the experience of the directed formation of Siberian pine forests ...

The microbiome in human skin aging

open access: yesFEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Early-arriving saproxylic beetles developing in Scots pine stumps: effects of felling type and date

open access: yesJournal of Forest Science, 2012
A total of 320 Scots pine (Pinus sylvestris L.) low stumps were analysed within two stands (one stand was thinned, and the other stand was subjected to clear-cut final felling) in the Drahanská Highlands in the Czech Republic. Each stand was divided into
