The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

An aerodynamic load criterion for airships [PDF]

open access: yes, 1975
A simple aerodynamic bending moment envelope is derived for conventionally shaped airships. This criterion is intended to be used, much like the Naval Architect's standard wave, for preliminary estimates of longitudinal strength requirements.

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

EVALUATING THE PERFORMANCE OF A HAMMER MILL THROUGH USING DIFFERENT TYPES OF LOCALLY MANUFACTURED HAMMERS [PDF]

open access: yesMesopotamia Journal of Agriculture
The study has investigated the effects of three factors, which were feeding rate, the rotational speed, and the type of used hammers on the some important indicators that could reflecting the performance of the hammer mill.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Optimizing the operating conditions of gold elution and electrowinning for Tau Lekoa stream at Kopanang gold plant [PDF]

open access: yes, 2008
The final gold product of Tau Lekoa mine has a low fineness. This is caused by high concentration of bases metals in the reefs. Some of these base metals together with gold are leached with cyanide and are loaded into carbon. If not adequately controlled,

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

THE STUDY OF IRREGULARITY ELONGATION OF YARNS OF WOOL IN MIXTURE WITH SILK USING THE USTER® TENSOJET 4 MACHINE [PDF]

open access: yesAnnals of the University of Oradea: Fascicle of Textiles, Leatherwork, 2015
The purpose of the study is to assess the irregularity elongation of wool yarn in a mixture with silk with the smoothness and torque of 470 Nm 34/1 twists / m, for knitted products.
