Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Plasma pTau181 enhances the prediction of future clinical decline in amyloid‐positive mild cognitive impairment

Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring
Plasma pTau181, a marker of amyloid and tau burden, was evaluated as a prognostic predictor of clinical decline and Alzheimer's disease (AD) progression of amyloid‐positive (Aβ+) patients with mild cognitive impairment (MCI).

Steady-state model of multi-port electric energy router and power flow analysis method of AC/DC hybrid system considering control strategies

The Journal of Engineering, 2019
This study proposes a steady-state model of multi-port electric energy router (EER) and a power flow analysis method for AC/DC hybrid system considering control strategies. Firstly, a circuit topology model of EER is put forward, including AC and DC port

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

GENERALIZED SPACES OF GENERAL RELATIVITY [PDF]

Proceedings of the National Academy of Sciences, 1959
1. This paper is a revision of the paper with the same title which was published a year ago. The paper deals with a space of four dimensions V4 of coordinates xi as i takes the values 1 to 4. The geometry of the space is based upon the asymmetric functions gij and the asymmetric coefficients of connection Prk and upon the Einsteinm equation2 gij,k ...
