Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.

In D-loop: 40years of mitochondrial 7S DNA
Experimental Gerontology, 2014 Given the tiny size of the mammalian mitochondrial genome, at only 16.5 kb, it is often surprising how little we know about some of its molecular features, and the molecular mechanisms governing its maintenance. One such conundrum is the biogenesis and function of the mitochondrial displacement loop (D-loop).

Evolution of the cetacean mitochondrial D-loop region. [PDF]
Molecular Biology and Evolution, 1991 We sequenced the mitochondrial DNA D-loop regions from two cetacean species and compared these with the published D-loop sequences of several other mammalian species, including one other cetacean. Nucleotide substitution rates, DNA sequence simplicity, possible open reading frames (ORFs), and potential RNA secondary structure were investigated.

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.

Mitochondrial control region alterations and breast cancer risk: a study in South Indian population. [PDF]
PLoS ONE, 2014 BACKGROUND: Mitochondrial displacement loop (D-loop) is the hot spot for mitochondrial DNA (mtDNA) alterations which influence the generation of cellular reactive oxygen species (ROS).

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)

PriA-directed Assembly of a Primosome on D Loop DNA [PDF]
Journal of Biological Chemistry, 1999 Escherichia coli strains carrying null mutations in priA are chronically induced for the SOS response and are defective in homologous recombination, repair of UV damaged DNA, double-strand break repair, and both induced and constitutive stable DNA replication.

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.
