Propensities of Fatty Acid-Modified ASOs: Self-Assembly vs Albumin Binding.

We conducted a biophysical study to investigate the self-assembling and albumin-binding propensities of a series of fatty acid-modified locked nucleic acid (LNA) antisense oligonucleotide (ASO) gapmers specific to the MALAT1 gene. To this end, a series of biophysical techniques were applied using label-free ASOs that were covalently modified with saturated fatty acids (FAs) of varying length, branching, and 5'/3' attachment. Using analytical ultracentrifugation (AUC), we demonstrate that ASOs conjugated with fatty acids longer than C16 exhibit an increasing tendency to form self-assembled vesicular structures.

Single-cell and bulk transcriptomics of the liver reveals potential targets of NASH with fibrosis.

Fibrosis is characterized by the excessive production of collagen and other extracellular matrix (ECM) components and represents a leading cause of morbidity and mortality worldwide. Previous studies of nonalcoholic steatohepatitis (NASH) with fibrosis were largely restricted to bulk transcriptome profiles. Thus, our understanding of this disease is limited by an incomplete characterization of liver cell types in general and hepatic stellate cells (HSCs) in particular, given that activated HSCs are the major hepatic fibrogenic cell population.

Molecular targets and approaches to restore autophagy and lysosomal capacity in neurodegenerative disorders.

Autophagy is a catabolic process that promotes cellular fitness by clearing aggregated protein species, pathogens and damaged organelles through lysosomal degradation. The autophagic process is particularly important in the nervous system where post-mitotic neurons rely heavily on protein and organelle quality control in order to maintain cellular health throughout the lifetime of the organism. Alterations of autophagy and lysosomal function are hallmarks of various neurodegenerative disorders.

When should splint treatment start for a tendinous mallet finger? A retrospective review of 319 fingers.

In a 5-year retrospective review of 319 tendinous mallet fingers, we focused on the result after splint treatment. The splint we used was a 'no pressure' thermoformed customized Stack splint. The patients wore it strictly for 8 weeks.

Belatacept associated - cytomegalovirus retinitis in a kidney transplant recipient: a case report and review of the literature.

Background: To report the first case of belatacept-associated multidrug-resistant Cytomegalovirus retinitis in a kidney transplant recipient.

Case Presentation: A 76-year-old African male renal allograft recipient was admitted for acute visual loss of the right eye. Ophthalmological examination of the right eye showed anterior uveitis and vitritis associated with large paravascular haemorrhages and yellow necrotic borders, involving the posterior pole but not the fovea.
