Oil Characterization, Molecular Modeling and Process Simulation in Petroleum Research and Industry, Opportunities, Challenges and Perspectives

Molecules
Petroleum is a valuable mineral resource from which base fuels and innumerable materials are produced. Its optimized utilization requires a deeper understanding of its chemistry, that can be obtained by improved characterization and molecular modeling ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Refined Quadripartitioned, Refined Pentapartitioned, Refined Heptapartitioned, and Iterative Refined Neutrosophic Logic

A Neutrosophic Set models uncertainty via three memberships—truth, indeterminacy, and falsity. We develop an n–Refined Neutrosophic Logic (n–RNL) that splits these into interpretable subcomponents and define refined quadripartitioned, pentapartitioned, and heptapartitioned families capturing contradiction, ignorance, unknown, and relative truth/falsity.

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 ...

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Optimizing the Bleaching Conditions for Mechanically Extracted and Solvent-Extracted Hempseed Oil

ChemEngineering
Hemp (Cannabis sativa) seed oil is recognized as a valuable oil due to its beneficial fatty acid profile, which includes a favorable balance of omega-6 and omega-3 fatty acids, making it highly desirable for edible and bioproduct applications.

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?

Assessment of the Active Sludge Microorganisms Population During Wastewater Treatment in a Micro-Pilot Plant

Bioengineering
Knowledge of the impact of chemicals on the environment is important for assessing the risks that chemicals can generate in ecosystems. With the help of pilot-scale micro-tests, it was possible to evaluate the biological sludge in terms of its chemical ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.
