From data to discovery: AI-guided analysis of disease-relevant molecules in spinal muscular atrophy (SMA).

Spinal Muscular Atrophy is caused by partial loss of survival of motoneuron (SMN) protein expression. The numerous interaction partners and mechanisms influenced by SMN loss result in a complex disease. Current treatments restore SMN protein levels to a certain extent, but do not cure all symptoms.

bootGSEA: a bootstrap and rank aggregation pipeline for multi-study and multi-omics enrichment analyses.

Gene set enrichment analysis (GSEA) subsequent to differential expression analysis is a standard step in transcriptomics and proteomics data analysis. Although many tools for this step are available, the results are often difficult to reproduce because set annotations can change in the databases, that is, new features can be added or existing features can be removed. Finally, such changes in set compositions can have an impact on biological interpretation.

Renal pathology in a mouse model of severe Spinal Muscular Atrophy is associated with downregulation of Glial Cell-Line Derived Neurotrophic Factor (GDNF).

Spinal muscular atrophy (SMA) occurs as a result of cell-ubiquitous depletion of the essential survival motor neuron (SMN) protein. Characteristic disease pathology is driven by a particular vulnerability of the ventral motor neurons of the spinal cord to decreased SMN. Perhaps not surprisingly, many other organ systems are also impacted by SMN depletion.

The Senescence-associated Secretory Phenotype Mediates Oncogene-induced Senescence in Pediatric Pilocytic Astrocytoma.

Purpose: Pilocytic astrocytoma is the most common childhood brain tumor, characterized by constitutive MAPK activation. MAPK signaling induces oncogene-induced senescence (OIS), which may cause unpredictable growth behavior of pilocytic astrocytomas. The senescence-associated secretory phenotype (SASP) has been shown to regulate OIS, but its role in pilocytic astrocytoma remains unknown.

Low-Income Texas Women's Experiences Accessing Their Desired Contraceptive Method at the First Postpartum Visit.

Context: Early access to contraception may increase postpartum contraceptive use. However, little is known about women's experiences receiving their desired method at the first postpartum visit or how access is associated with use.

Methods: In a 2014-2016 prospective cohort study of low-income Texas women, data were collected from 685 individuals who desired a reversible contraceptive and discussed contraception with a provider at their first postpartum visit, usually within six weeks of birth.

[Evaluation of velopharyngeal closing pressure during trumpet play with high-resolution manometry].

Objective: In about one-third of brass instrumentalists, there are stress-related insufficiencies of velopharyngeal closure (VPC), i. e. the intraoral pressure exceeds the barrier formed by the VPC.

Evidence of promiscuous endothelial binding by Plasmodium falciparum-infected erythrocytes.

The adhesion of infected red blood cells (iRBCs) to human endothelium is considered a key event in the pathogenesis of cerebral malaria and other life-threatening complications caused by the most prevalent malaria parasite Plasmodium falciparum. In the past 30 years, 14 endothelial receptors for iRBCs have been identified. Exposing 10 additional surface proteins of endothelial cells to a mixture of P.

Electrical stimulation in treatment of pharyngolaryngeal dysfunctions.

Objective: Neuromuscular electrical stimulation (NMES) has been proposed in the treatment of laryngopharyngeal dysfunctions (dysphonia, dyspnoea, dysphagia) for more than 40 years. Several studies have investigated possible therapeutic effects. Some researchers described favourable results, whereas others did not find relevant benefits.

Prenatal nicotine and/or cocaine differentially alters nicotine-induced sensitization in aging offspring.

Repeated exposure to psychostimulant drugs can result in behavioral sensitization, an amplified response in locomotor activity and stereotypy, which is used to model aspects of drug addiction. The expression of behavioral sensitization, induced by i.p.

Promoter polymorphism of the anion-exchange protein 1 associated with severe malarial anemia and fatality.

The anion-exchange protein 1 (AE1 or band 3) is involved in the erythrocyte invasion of the malaria parasite Plasmodium falciparum, the adhesion of infected erythrocytes to endothelial cells, and the regulation of acid-base homeostasis, which is a critical factor for human survival in severe malaria. A variant of the AE1 gene promoter 512 base pairs (bp) distant from the transcription start site and 5699 bp from the translation start codon (AE1(-5699T-->C)) has been shown to be highly frequent in a population from the Ashanti region, Ghana. In a matched-pair case-control study (736 pairs), children heterozygous for the mutation (AE1(-5699CT)) had an increased risk of severe malarial anemia (odds ratio [OR], 1.

LmxPK4, a mitogen-activated protein kinase kinase homologue of Leishmania mexicana with a potential role in parasite differentiation.

Members of the mitogen-activated protein (MAP) kinase cascade are important for the establishment of a Leishmania mexicana infection and are involved in flagellar length control, although the underlying molecular mechanisms remain to be elucidated. This study reports the cloning and characterization of LmxPK4, a MAP kinase kinase homologue of L. mexicana displaying putative plant-like regulatory phosphorylation sites.

LmxMPK9, a mitogen-activated protein kinase homologue affects flagellar length in Leishmania mexicana.

Components of mitogen-activated signal transduction pathways have been shown to be involved in flagellum biogenesis and maintenance. A mitogen-activated protein kinase homologue, designated LmxMPK9 from Leishmania mexicana, has been recently identified in a homology screen and its mRNA found to be present in all life stages. Three different splice-addition sites were used for mRNA maturation in trans-splicing in the different life stages.

Protein kinase involved in flagellar-length control.

During its life cycle, the parasitic protozoon Leishmania mexicana differentiates from a flagellated form, the promastigote, to an amastigote form carrying a rudimentary flagellum. Besides biochemical changes, this process involves a change in overall cell morphology including flagellar shortening. A mitogen-activated protein kinase kinase homologue designated LmxMKK was identified in a homology screening and found to be critically involved in the regulation of flagellar assembly and cell size.
