Répartition des bactéries dans les sédiments du lac de Constance

, 2011
La répartition des bactéries dans les sédiments du Lac de Constance a été étudiée à l'aide de la méthode de Koch sur milieu peptoné. Trois sédiments typiques ont été choisis pour les prélèvements : l'un dans la zone littorale (Güttingen), les deux autres

Instabilità delle LAC morbide toriche: influenza sulla qualità visiva attraverso la valutazione aberrometrica. Instability of soft toric contact lens: influence in visual quality throught the evaluation of wavefront aberrations. Relatore: Prof. [PDF]

, 2022
L'obiettivo è di capire in che modo le aberrazioni, valutate con il parametro dell’RMS, variano nei portatori di LAC toriche, al termine di ogni movimento oculare e come questo influisca sulla perfomance visiva, attraverso la variazione dell'acuita ...

From Defense Executor to Engineering Target: Harnessing Lignin for Crop Resistance

Advanced Science, EarlyView.
Lignin serves as both a physical and chemical executor of broad‐spectrum plant immunity. This review systematically summarizes classical and recent advances in lignin‐mediated immunity, outlines the multifaceted regulatory modules controlling lignification under biotic stress, discusses key physiological and biochemical mechanisms behind lignin‐based ...

Neuron‐Derived MIF Engages VCAM1 to Fuel a Self‐Amplifying CXCL8 Loop That Drives Perineural Invasion and Metastasis in Gastric Cancer

Advanced Science, EarlyView.
Neuron‐derived MIF binds VCAM1 on gastric cancer cells and activates ERK/STAT3 signaling, leading to CXCL8 transcription and secretion. Tumor‐derived CXCL8 subsequently stimulates neuronal CXCR2 to enhance MIF production, establishing a self‐amplifying MIF–VCAM1–CXCL8 positive‐feedback loop that promotes perineural invasion, tumor progression, and ...

Lactate‐Driven Restriction of Mitochondrial Permeability Transition Promotes Resistance to Chemo‐Immunotherapy by Suppressing Tumor PANoptosis

Advanced Science, EarlyView.
Tumor‐derived lactate establishes a metabolic lock that drives chemo‐immunotherapy resistance by suppressing PANoptosis. Mechanistically, KAT8 lactylates the mitochondrial translocator ANT2, which recruits PGAM5 to dephosphorylate CypD. This cascade restricts mitochondrial permeability transition pore opening, preventing pro‐inflammatory mtDNA leakage.

Pathological Copper Overload Reprograms SOD1 Activation via COMMD1 to Promote Senescence and Fibrosis

Advanced Science, EarlyView.
This study uncovers a previously unrecognized copper‐COMMD1‐SOD1 regulatory axis, revealing that pathological copper overload paradoxically suppresses SOD1 activity by promoting COMMD1‐dependent disruption of SOD1 homodimerization. These findings redefine the regulatory role of copper in SOD1 biology and provide novel mechanistic insight into the ...
