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

FEBS 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.

A Utility-Based Rate Allocation of M2M Service in Heterogeneous Wireless Environments

International Journal of Distributed Sensor Networks, 2013
This paper presents a dynamic adaptive machine-to-machine (M2M) service rate allocation scheme for optimum traffic distribution in heterogeneous wireless environments (HWEs). According to the M2M service characteristics, it proposes the utility function,

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

First records of the Indo-Pacific Finless Porpoise Neophocaena phocaenoides (G. Cuvier, 1829) (Cetartiodactyla: Phocoenidae) from Sri Lanka

Journal of Threatened Taxa, 2017
Thirty species of marine mammals have been recorded from Sri Lanka.  Amongst them the Indo-Pacific Finless Porpoise Neophocaena phocaenoides is the only representative of the family Phocoenidae.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

„Legalizować czy nie?” – analiza związku pomiędzy stosowaniem kanabinoli a częstością występowania i obrazem klinicznym zaburzeń psychotycznych

Psychiatria i Psychologia Kliniczna, 2010
Związek pomiędzy zażywaniem kanabinoli a występowaniem zaburzeń psychotycznych jest opisywany od dawna. Udowodniono między innymi, że kanabinole mogą wywoływać przemijające objawy pozytywne, negatywne i poznawcze psychozy u zdrowych osób oraz zaostrzać ...

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
