Safe and effective in vivo delivery of DNA and RNA using proteolipid vehicles.

Genetic medicines show promise for treating various diseases, yet clinical success has been limited by tolerability, scalability, and immunogenicity issues of current delivery platforms. To overcome these, we developed a proteolipid vehicle (PLV) by combining features from viral and non-viral approaches. PLVs incorporate fusion-associated small transmembrane (FAST) proteins isolated from fusogenic orthoreoviruses into a well-tolerated lipid formulation, using scalable microfluidic mixing.

Characterization of the radiation beam of a tomotherapy equipment with MCNP.

This work aims to model and characterize the radiation beam of one Accuray tomotherapy equipment using the Monte Carlo Code MCNP5 (Monte Carlo N-Particle). This tomotherapy equipment is used for delivering high doses of radiation in tumor regions to kill cancer cells and shrink the tumor during radiation therapy of cancer patients, however, the radiation can damage surrounding areas and nearby organs at risk (OAR) if the radiation field is not well delimited. In particular, intensity-modulated radiotherapy treatments (IMRT) with tomotherapy equipment offer great benefits to patients allowing treatment of tumor regions without affecting surrounding areas and OAR.

Fetal coenzyme Q10 deficiency in intrahepatic cholestasis of pregnancy.

Aim: Intrahepatic cholestasis of pregnancy (ICP) is considered a high-risk condition because it may have serious consequences for the fetus health. ICP is characterized by the accumulation of bile acids in maternal serum which contribute to an imbalance between the production of reactive oxygen species and the antioxidant defenses increasing the oxidative stress experienced by the fetus. Previously, it was reported a significant decrease in plasma coenzyme Q10 (CoQ10) in women with ICP.

Validation of a High-throughput Screening and Quantification Method for the Determination of Gabapentinoids in Blood Using a Combination of LC-TOF-MS and LC-MS-MS.

Gabapentinoids such as gabapentin (GP) and pregabalin (PGL) have been used to treat a wide range of neurological and psychiatric disorders. In recent years, there has been an increasing awareness of GP and PGL misuse among individuals with a history of polysubstance use. Both GP and PGL are understood to potentiate the effects of opioids, with fatalities involving GP and PGL being reported with increasing frequency.

Testing the effectiveness of conservation management within biosphere reserves: the case of the Mexican deer mouse (Peromyscus mexicanus) as a bioindicator.

Biosphere reserves are protected areas whose purpose is to combine conservation and sustainable development. However, their effectiveness has not been tested sufficiently, especially from an ecological and genetic approach. In this sense, the Peromyscus genus represents an excellent bioindicator to address these questions, due to its short life and high evolutionary rate and fecundity.

[Long-term effect of policosanol on the functional recovery of non-cardioembolic ischemic stroke patients: a one year study].

Introduction: Stroke is a leading cause of mortality and disability. Policosanol has been effective in brain ischemia models. The aim of this study is to investigate whether policosanol, added to aspirin therapy within 30 days of stroke onset, is better than placebo + aspirine for the long-term recovery of non-cardioembolic ischemic stroke subjects.

ATP6V1H Deficiency Impairs Bone Development through Activation of MMP9 and MMP13.

ATP6V1H is a component of a large protein complex with vacuolar ATPase (V-ATPase) activity. We identified two generations of individuals in which short stature and osteoporosis co-segregated with a mutation in ATP6V1H. Since V-ATPases are highly conserved between human and zebrafish, we generated loss-of-function mutants in atp6v1h in zebrafish through CRISPR/Cas9-mediated gene knockout.

The rise of proteostasis promoters.

Molecular chaperones are specialized proteins essential for facilitating the correct folding, assembly, and disassembly of many cellular proteins and for assuring proteostasis. Genetic mutations or metabolic extremes that cause long-term alteration of cellular homeostasis compromise protein folding efficiency. To maintain proteostasis, cells mobilized stress coping responses that include the unfolded protein response in order to prevent accumulation of improperly folded proteins that forms the basis of many diseases.
