Abstract Background Choroidal metastasis is the most common intraocular malignancy in adults, commonly presenting in later stages of the disease and associated with poor prognosis.This is the first case to describe choroidal involvement as the sole initial metastasis of the rare biphasic pulmonary tumor.Case presentation A 42-year-old white male pa
Overexpression of lpxT Gene in Escherichia coli Inhibits Cell Division and Causes Envelope Defects without Changing the Overall Phosphorylation Level of Lipid A
LpxT is an inner membrane protein that transfers a phosphate group from the essential lipid undecaprenyl pyrophosphate (C-55PP) to the lipid A moiety of lipopolysaccharide, generating a lipid A tris-phosphorylated species.The protein is encoded by the non-essential lpxT gene, which is conserved in distantly related Gram-negative bacteria.In this wo
The Expression Levels of Heat Shock Protein 90 (HSP90) in Galleria mellonella Following Infection with the Entomopathogenic Nematode Steinernema carpocapsae and Its Symbiotic Bacteria Xenorhabdus nematophila
Heat shock proteins (HSPs), particularly HSP90, play a vital role in insect responses to Disinfectant Wipes environmental and biotic stresses by maintaining protein stability and supporting immune defenses.This study explores HSP90 regulation in Galleria mellonella larvae following exposure to the nematode Steinernema carpocapsae and its symbiotic
