Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Evaluation of Response Reduction Factor of Irregular Reinforced Concrete Framed Structures

Indian Journal of Science and Technology, 2016
Background/Objectives: Most of the seismic codes used today, incorporate the nonlinear response of a structure by the provision of an appropriate response reduction factor ‘R’ so that a linear elastic force based approach can be used for design. The value of R factor varies from 3 to 5 in IS 1893 for RC moment resisting frames, but it does not provide ...

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)

Uninephrectomy in rats on a fixed food intake potentiates both anorexia and circulating cytokine subsets in response to LPS.

Frontiers in Immunology, 2015
Recent human studies have suggested that mild reduction in kidney function can alter immune response and increase susceptibility to infection. The role of mild reduction in kidney function in altering susceptibility to bacterial lipopolysaccharide (LPS ...

Effect of Lintel Beam on Response Reduction Factor of RC-Infilled Frames

Current Science, 2020
In this study, a three-dimensional, four-storied, rein-forced concrete (RC) building is designed for seismic zone-IV and seismically evaluated for different infill configurations along with consideration of openings in infills to develop a realistic model. Four models are considered, i.e.

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 ...

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.

Differential Regulation of the Heat Shock Factor 1 and DAF-16 by Neuronal nhl-1 in the Nematode C. elegans

Cell Reports, 2014
In the nematode Caenorhabditis elegans, insulin/insulin-like growth factor 1 (IGF-1) signaling (IIS) reduction hyperactivates the transcription factors DAF-16 and heat shock factor 1 (HSF-1), creating long-lived, stress-resistant worms that are protected
