Tropical Homology

, 2017
Given a tropical variety X and two non-negative integers p and q we define homology group $H_{p,q}(X)$. We show that if X is a smooth tropical variety that can be represented as the tropical limit of a 1-parameter family of complex projective varieties ...

Homological properties of persistent homology

Journal of Algebra and Its Applications
In this paper, we investigate to what extent persistent homology benefits from the properties of a homology theory. We show that persistent homology benefits from a Mayer–Vietoris sequence and a long exact sequence for a pair if one works with graded persistence modules.

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.

Between utopia and tragedy: the convergence of Faustian motif of “homunculus” and the key images of the novel “Doctor Zhivago” by B. Pasternak

Неофилология, 2023
The purpose of study is to identify the semantic and figurative parallels of the second part of Goethe’s “Faust” and B.L. Pasternak’s novel “Doctor Zhivago”.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

The establishment of a GPD1L knockout human embryonic stem cell line (WAe009-A-80) using the CRISPR/Cas9 system

Stem Cell Research
The GPD1L gene is located on 3p22.3. It encodes the glycerol phosphate dehydrogenase 1-like protein with homology to glycerol phosphate dehydrogenase (GPD1L), but the function of this enzyme is unclear.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Therapeutic potential of 20-Hydroxyecdysone in pulmonary arterial hypertension: involvement of Mas receptor and PI3K–Akt pathway

Cellular & Molecular Biology Letters
Background 20-Hydroxyecdysone (20E), a natural polyhydroxylated steroid found in various edible plants, exhibits diverse pharmacological effects. Pulmonary arterial hypertension (PAH) remains challenging to treat owing to its multifactorial pathogenesis.
