Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

An Unusual Cause of Biliary Obstruction [PDF]

, 2012
Portal biliary ductopathy (PBD) is a condition in which biliary and pancreatic ducts are extrinsically compressed by collateral branches of the portal venous system, which in turn have become dilated and varicosed due to portal hypertension.

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Climate Obstruction in Germany : Hidden in Plain Sight?

Since the inclusion of ecological considerations in Germany’s social market economy model in the 1990s and the approval of the Renewable Energy Sources Act (RESA) in 2000, the debate on climate policy in Germany has intensified.

Why I'm fighting alcohol industry obstruction of minimum pricing [PDF]

, 2014
First paragraph: Exactly a year after minimum alcohol pricing was supposed to have been introduced in Scotland, this week a group of public health professionals including myself registered a protest against the fact that it is still not in place. Access

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

FEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

Snapshot in surgery: How do you approach this 12‐year‐old girl?

Clinical Case Reports, 2018
Key Clinical Message This case open questions about the dimensional limit for a laparoscopic treatment of a giant bezoar. A minimally invasive option should be considered every time a gastric obstruction is suspected, particularly for psychiatric ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Elimination of Large Bladder Stone-Obstructing Pelvic Canal in African Spurred Tortoise (Centrochelys sulcata) with Per-Cloacal Bladder Stone Removal Method without Utilizing an Endoscope

Media Kedokteran Hewan
Bladder stone formation in reptiles arises from the accumulation and subsequent solidification of uric acid in the urinary bladder. The bladder stones vary in size and can migrate from the bladder to the pelvic canal. In cases where larger bladder stones

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?
