Nerves and Anesthesia: A physics perspective on medicine [PDF]

open access: yesAnestezjologia i Ratownictwo 2014; 8: 252-263, 2014
We present a recent theory for nerve pulse propagation and anesthesia and argue that both nerve activity and the action of anesthetics can be understood on the basis of simple physical laws. It was found experimentally that biological membranes melt from a solid state to a liquid state just below physiological temperature. Such melting processes have a

Engineering Extracellular Vesicles Derived from 3D Cultivation of BMSCs Enriched with HGF Ameliorate Sepsis‐Induced Lung Epithelial Barrier Damage

open access: yesAdvanced Science, EarlyView.
3D culture of MSCs upregulates gene expression of matrix metalloproteinases (MMPs), growth factors (GFs), and increases the production of extracellular vesicles (EVs). Proteomic analysis reveals 642 upregulated proteins in 3D‐EVs, including HGF. These 3D‐EVs, enriched with HGF, protect lung epithelial cells from apoptosis and barrier damage in septic ...

The Modeling and Quantification of Rhythmic to Non-rhythmic Phenomenon in Electrocardiography during Anesthesia [PDF]

open access: yesarXiv, 2015
Variations of instantaneous heart rate appears regularly oscillatory in deeper levels of anesthesia and less regular in lighter levels of anesthesia. It is impossible to observe this "rhythmic-to-non-rhythmic" phenomenon from raw electrocardiography waveform in current standard anesthesia monitors. To explore the possible clinical value, I proposed the

MAGEA6 Engages a YY1‐Dependent Transcription to Dictate Perineural Invasion in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
This study investigates the role of MAGEA6 in perineural invasion (PNI) in colorectal cancer (CRC). MAGEA6 promotes CRC invasiveness by inhibiting YY1 ubiquitination, enhancing CXCL1 secretion, and recruiting Schwann cells. These findings highlight the potential of targeting the MAGEA6/YY1/CXCL1 axis for therapeutic strategies against PNI and tumor ...

Anesthesia for non-obstetric surgery during late term pregnancy in mares.

open access: yesPLoS ONE
Submitting late-term pregnant mares to anesthesia for non-obstetric surgery raises concerns about the survival of the mother and fetus. This study aimed to evaluate and describe transient maternal and fetal hemodynamic changes during general inhalation ...

IFITM2 Modulates Endocytosis Maintaining Neural Stem Cells in Developing Neocortex

open access: yesAdvanced Science, EarlyView.
This study reveals IFITM2 as a key regulator of endocytosis in radial glial cells (RGCs) during brain development. IFITM2's YXXø motif and phosphoinositide‐binding residues (K82/K87) are essential for endosome formation. IFITM2 deficiency disrupts the embryonic cortical neurogenesis, revealing a conserved mechanism linking endocytic dynamics to neural ...

CD11b+CD43hiLy6Clo splenocyte‐derived macrophages exacerbate liver fibrosis via spleen–liver axis

open access: yesHepatology, EarlyView., 2022
A population of splenic monocytes migrate into the liver and shift to macrophages, which account for the exacerbation of liver fibrosis. Abstract Background and Aims Monocyte‐derived macrophages (MoMFs), a dominant population of hepatic macrophages under inflammation, play a crucial role in liver fibrosis progression.

Cardiac Slc25a49‐Mediated Energy Reprogramming Governs Doxorubicin‐Induced Cardiomyopathy through the G6P–AP‐1–Sln Axis

open access: yesAdvanced Science, EarlyView.
Doxorubicin‐induced cardiomyopathy involves mitochondrial energy metabolism dysfunction, exacerbated by cardiomyocyte‐specific Slc25a49 deficiency via oxidative phosphorylation (OXPHOS) suppression and glycolysis activation. The Slc25a49–glucose‐6‐phosphate (G6P)–activator protein‐1 (AP‐1) axis drives myocardial injury by upregulating Sln, disrupting ...
