Poa secunda J. Presl (Poaceae): a modern summary of infraspecific taxonomy, chromosome numbers, related species and infrageneric placement based on DNA

open access: yesPhytoKeys, 2018
Poa secunda J. Presl. s.l. is a morphologically highly variable bunchgrass that is a valuable forage species in western North America. There has been much controversy as to whether multiple taxa should be recognised and at what rank in this taxonomically

Bioengineering facets of the tumor microenvironment in 3D tumor models: insights into cellular, biophysical and biochemical interactions

open access: yesFEBS Open Bio, EarlyView.
The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.

Odonata collection of the Croatian Natural History Museum

open access: yesNatura Croatica, 2018
A total of 1, 545 Odonata specimens stored in the collection of the Croatian Natural History Museum in Zagreb have been examined. The specimens were collected in the period between 1869 and 2011, mainly in Croatia, but also in the surrounding countries (Austria, Bosnia and Herzegovina, Italy, Montenegro, Serbia, Slovenia) and Switzerland.

Possible role of human ribonuclease dicer in the regulation of R loops

open access: yesFEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

Iron‐dependent lysosomal LDL oxidation induces the expression of scavenger receptor A in human THP‐1 monocytes

open access: yesFEBS Open Bio, EarlyView.
In human monocytic cells THP‐1, a limited uptake of native—not oxidized—LDL/VLDL induced expression of scavenger receptor A and cellular adhesion. Induction was inhibited by lysosomotropic (WR‐1065) and lipophilic (BHT) antioxidants and by siRNAs against ferritinophagy.

The impact of frailty syndrome on skeletal muscle histology: preventive effects of exercise

open access: yesFEBS Open Bio, EarlyView.
Frailty syndrome exacerbates skeletal muscle degeneration via increased ECM deposition and myofiber loss. This study, using a murine model, demonstrates that endurance exercise attenuates these histopathological alterations, preserving muscle integrity. Findings support exercise as a viable strategy to counteract frailty‐induced musculoskeletal decline

Distribution and taxonomy of two closely related Nychiodes species in southern Italy (Lepidoptera, Geometridae, Ennominae) [PDF]

open access: yesNota Lepidopterologica
We investigated the distribution and species circumscription of Nychiodes obscuraria Villers (1789) and Nychiodes ragusaria Millière (1884). The morphology of male and female genitalia of Calabrian populations (southern Italy) revealed them to belong to ...

Development of 4T1 breast cancer mouse model system for preclinical carbonic anhydrase IX studies

open access: yesFEBS Open Bio, EarlyView.
Carbonic anhydrase IX (CAIX) is a well‐recognised therapeutic target and prognostic biomarker in cancer. We developed and characterised a robust murine breast cancer model system that is suitable for CAIX studies in vitro and in vivo—it comprises both CAIX‐positive and CAIX‐negative controls and provides a solid platform for the comprehensive ...
