Differentially expressed lncRNAs in SOD1 mice skeletal muscle: H19, Myhas and Neat1 as potential biomarkers in amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) is a devastating neuromuscular disease characterized by progressive motor function and muscle mass loss. Despite extensive research in the field, the underlying causes of ALS remain incompletely understood, contributing to the absence of specific diagnostic and prognostic biomarkers and effective therapies. This study investigates the expression of long-non-coding RNAs (lncRNAs) in skeletal muscle as a potential source of biomarkers and therapeutic targets for the disease.

Characterizing Leishmania infantum-induced resistance to trivalent stibogluconate (SbIII) through deep proteomics.

Leishmania infantum belongs to the L. donovani complex, which includes species associated with visceral leishmaniasis. Traditionally, antimonial compounds have served as the primary antiparasitic treatment for all clinical forms of leishmaniasis.

Proteomic profiling of human plasma extracellular vesicles identifies PF4 and C1R as novel biomarker in sarcopenia.

Background: Sarcopenia, the gradual and generalized loss of muscle mass and function with ageing, is one of the major health problems in older adults, given its high prevalence and substantial socioeconomic implications. Despite the extensive efforts to reach consensus on definition and diagnostic tests and cut-offs for sarcopenia, there is an urgent and unmet need for non-invasive, specific and sensitive biomarkers for the disease. Extracellular vesicles (EVs) are present in different biofluids including plasma, whose cargo reflects cellular physiology.

Sex differences on constitutive long non-coding RNA expression: Modulatory effect of estradiol and testosterone in muscle cells.

Introduction: Despite the growing awareness of sexual dimorphism between males and females under pathological and physiological conditions, sex bias in biomedical research in animal models and patients is still present nowadays. The main objective of this work was to investigate sex differences in constitutive long non-coding RNA expression in spinal cord and skeletal muscle from wild-type mice.

Materials And Methods: To assess the influence of gender on long non-coding RNAs, we extracted RNA from tissues of male and female mice and analyzed the expression on nine long non-coding RNAs, selected for being among the most commonly studied or exerting an important role in muscle, at 50, 60, and 120 days of age.

Poly(imidazolyliden-yl)borato Complexes of Tungsten: Mapping Steric vs. Electronic Features of Coordinating Ligands.

A convenient synthesis of [HB(HImMe)](PF) (ImMe = -methylimidazolyl) is decribed. This salt serves in situ as a precursor to the tris(imidazolylidenyl)borate Li[HB(ImMe)] pro-ligand upon deprotonation with BuLi. Reaction with [W(≡CCHMe-4)(CO)(pic)(Br)] (pic = 4-picoline) affords the carbyne complex [W(≡CCHMe-4)(CO){HB(ImMe)}].
