Synaptic dysfunction is recognized as an early step in the pathophysiology of parkinsonism. Several genetic mutations affecting the integrity of synaptic proteins cause or increase the risk of developing disease. We have identified a candidate causative mutation in synaptic "SH3GL2 Interacting Protein 1" (SGIP1), linked to early-onset parkinsonism in a consanguineous Arab family.

The quantification of pesticide dissipation in agricultural soil is challenging. In this study, we investigated atrazine biodegradation in both liquid and soil experiments bioaugmented with distinct atrazine-degrading bacterial isolates. This was achieved by combining C-mineralisation assays and compound-specific isotope analysis of atrazine.

Article Synopsis
  • Rhabdomyosarcoma (RMS) treatment has improved, but high-risk patients still struggle with poor survival rates due to issues like PAX3/7-FOXO1 fusion proteins that cause metastasis and resistance to therapy.
  • This study focused on TRIB3, a regulator of FOXO1, finding that higher TRIB3 expression in RMS tumors correlates with the fusion protein's presence and contributes to cell proliferation.
  • Genetic inhibition of TRIB3 not only reduced PAX3-FOXO1 levels and affected signaling pathways but also delayed tumor growth and improved survival rates in vivo, indicating TRIB3 could be a promising therapeutic target for aggressive RMS.

The human immunodeficiency virus type 1 (HIV-1) reservoir, composed of cells harboring the latent, integrated virus, is not eliminated by antiretroviral therapy. It therefore represents a significant barrier to curing the infection. The biology of HIV-1 reservoirs, the mechanisms of their persistence, and effective strategies for their eradication are not entirely understood.

We print a tunable photopolymer (photopolymer dispersed liquid crystal -PDLC), using the laser-induced direct transfer technique without absorber layer, which was a challenge for this technique given the low absorption and high viscosity of PDLC, and which had not been achieved so far to our knowledge. This makes the LIFT printing process faster and cleaner and achieves a high-quality printed droplet (aspheric profile and low roughness). A femtosecond laser was needed to reach sufficiently peak energies to induce nonlinear absorption and eject the polymer onto a substrate.

Impedance spectroscopy has been widely used for the study of the electrical properties of membranes for their characterization. The most common use of this technique is the measure of the conductivity of different electrolyte solutions to study the behavior and movement of electrically charged particles inside the pores of membranes. The objective of this investigation was to observe if there is a relation present between the retention that a nanofiltration membrane possesses to certain electrolytic solutions (NaCl, KCl, MgCl, CaCl, and NaSO) and the parameters that are obtained through IS measurements of the active layer of the membrane.

Article Synopsis
  • - Cancer patients are at higher risk for severe COVID-19 illness, making effective vaccination strategies—like booster doses—essential for their protection against the virus and its variants.
  • - A clinical trial showed that a third mRNA COVID-19 vaccine dose led to a significant immune response in 57% of previously seronegative cancer patients, and that this response remained strong after 6 months.
  • - Among severely immunocompromised patients who didn't respond well after the third dose, a fourth dose resulted in a sufficient immune boost for 67% of them, though overall neutralization against the Omicron variant was limited.

Neuronal activity causes use-dependent decline in protein function. However, it is unclear how this is coupled to local quality control mechanisms. We show in Drosophila that the endocytic protein Endophilin-A (EndoA) connects activity-induced calcium influx to synaptic autophagy and neuronal survival in a Parkinson disease-relevant fashion.

Novel adjuvants are highly desired to improve immune responses of SARS-CoV-2 vaccines. This work reports the potential of the stimulator of interferon genes (STING) agonist adjuvant, the cyclic di-adenosine monophosphate (c-di-AMP), in a SARS-CoV-2 vaccine based on the receptor binding domain (RBD). Here, mice immunized with two doses of monomeric RBD adjuvanted with c-di-AMP intramuscularly were found to exhibit stronger immune responses compared to mice vaccinated with RBD adjuvanted with aluminum hydroxide (Al(OH) ) or without adjuvant.
