Novel insights into the assembly of the yeast translation initiation multifactor complex: The critical role of eIF5. [PDF]

open access: yesProtein Sci
Abstract The eukaryotic translation initiation is a biological process in which at least a dozen eukaryotic initiation factors (eIFs) are involved. Specifically, eIF3, eIF1, eIF5, and eIF2 as a ternary complex (eIF2‐TC) bound to GTP and methionyl initiator tRNA (Met‐tRNAiMet).

Comparison of synthetic membranes in the development of an in vitro feeding system for Dermanyssus gallinae [PDF]

open access: yes, 2010
Although artificial feeding models for the poultry red mite (Dermanyssus gallinae) most frequently use biological membranes consisting of day-old chick skin, there are ethical considerations associated with the use of skin.

The preparation and characterization of alumina membranes with ultra-fine pores : Part 4. Ultrafiltration and hyperfiltration experiments [PDF]

open access: yes, 1985
The rejection characteristics of three types of alumina membranes for polyethylene glycol (PEG) polymers and dextrans soluted in water have been investigated. If the temperature at which the membranes are treated is increased, the pore size increases and

Why Successful Performance in Imagery Tasks Does not Require the Manipulation of Mental Imagery [PDF]

open access: yes, 2019
Nanay (2017) argues for unconscious mental imagery, inter alia based on the assumption that successful performance in imagery tasks requires the manipulation of mental imagery. I challenge this assumption with the help of results presented in Shepard and

The effects of a higher amount of iodine supplement on the efficiency of laying hens fed extruded rapeseed and on eggshell quality

open access: yesCzech Journal of Animal Science, 2004
The objective of this experiment was to study the effects of feeding 6.07 mg/kg of iodine in comparison with 3.57 mg/kg of iodine as a supplement in diets with different levels of extruded rapeseed (4.5, 9.0 and 13.5%) for a period of 52 weeks.

The effect of different wavelengths of light during incubation on the development of rhythmic pineal melatonin biosynthesis in chick embryos

open access: yesAnimal, 2019
Rhythmic pineal melatonin biosynthesis develops in chick embryos incubated under a light (L)-dark (D) cycle of polychromatic white light. The spectral sensitivity of the embryonic pineal gland is not known and was investigated in this study.
