Relativistic MOND from Modified Energetics [PDF]

open access: yes, 2014
We begin to investigate the question of what modifications in energy-momentum tensor can yield correct MOND regime. As a starting study, we refrain from insisting on an action principle and focus exclusively on the equations of motion.

Hematopoietic (stem) cells—The elixir of life?

open access: yesFEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Ketogenic Diet Mechanism of Action

open access: yesPediatric Neurology Briefs, 1996
The intracellular pH of the cerebral cortex was studied by the neutral red method in 15 adult rats maintained on ketogenic and control diets for 5-6 weeks.

Anomaly inflow mechanism using Wilson line

open access: yes, 2007
It is shown that the anomaly inflow mechanism can be implemented using Wilson line in odd dimensional gauge theories. An action of Wess-Zumino-Witten (WZW) type can be constructed using Wilson line.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Mechanisms of Resistance to Chemotherapy in Hypopharyngeal Carcinoma

open access: yesBiomedicines
Hypopharyngeal carcinoma (HPC) represents the most prognostically unfavorable subtype among head and neck malignancies. Platinum-based neoadjuvant chemotherapy serves as a critical therapeutic approach for improving outcomes in hypopharyngeal carcinoma ...

A Note on the Chiral Anomaly in the AdS/CFT Correspondence and 1/N^2 Correction [PDF]

open access: yes, 1999
According to the AdS/CFT correspondence,the d=4, N=4 SU(N) SYM is dual to the Type IIB string theory compactified on AdS_5xS^5. A mechanism was proposed previously that the chiral anomaly of the gauge theory is accounted for to the leading order in N by ...

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

open access: yesFEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Flavonoids – An Amazing Group of Compounds with Potent Antimicrobial Properties [PDF]

open access: yesMemoirs of the Scientific Sections of the Romanian Academy, 2019
Antibiotic resistance is spreading all around the world, many infectious diseases are becoming more and more severe and sometimes impossible to treat, therefore new efficient solutions are desperately needed.
