Determining the number of viable cells by calculating colony-forming units is time-consuming. The evaluation of mixed biofilms consisting of different species is particularly problematic. Therefore, the aim of this study was to optimize a molecular method-propidium monoazide quantitative polymerase chain reaction (PMA-qPCR)-for accurate and consistent differentiation between living and dead cells.

Article Synopsis
  • The study investigates the impact of Shank3 deficiency on dopaminergic neurons in mouse models relevant to autism.
  • Significant reductions in neurite outgrowth and altered morphology of dopaminergic neurons were observed in Shank3-deficient mice compared to wild-type (WT) mice.
  • Although there were no changes in the expression of synaptic proteins, shifts in dopaminergic receptor gene expression suggest structural alterations may contribute to autistic symptoms in these models.

Pangenomes are becoming a powerful framework to perform many bioinformatics analyses taking into account the genetic variability of a population, thus reducing the bias introduced by a single reference genome. With the wider diffusion of pangenomes, integrating genetic variability with transcriptome diversity is becoming a natural extension that demands specific methods for its exploration. In this work, we extend the notion of spliced pangenomes to that of annotated spliced pangenomes; this allows us to introduce a formal definition of Alternative Splicing (AS) events on a graph structure.

This study presents a novel rapid analytical method for the detection of volatile organic compounds (VOCs) emitted from blueberry leaves using the Tenax adsorbent followed by separation using a multicapillary column (MCC) and Ion Mobility Spectrometry (IMS) detection. The emitted VOCs including caryophyllene, benzene acetonitrile, linalool, ocimene, and methyl salicylate initiated by different stress factors including mechanical damage (punching), herbivore attack (aphids) and methyl jasmonate (MeJA) spraying were detected and quantified. Limits of Detection (LODs) for the VOCs were determined in the range of 8 to 33 ng.

Investigation of glucosuria in children.

Minerva Pediatr (Torino)

December 2024

Department of Pediatrics, Second Faculty of Medicine, Motol University Hospital, Charles University, Prague, Czech Republic.

Article Synopsis
  • Previous recommendations on diagnosing familial renal glucosuria lacked a comprehensive understanding of glucosuria's differential diagnosis.
  • This review aims to summarize the various causes of glucosuria and propose an evidence-based diagnostic approach for children affected by it.
  • The findings indicate that several factors, including genetic and acquired conditions, can impact glucose reabsorption in the kidneys, necessitating the exclusion of diabetes mellitus and other hyperglycemia-related conditions before making a diagnosis.

Article Synopsis
  • The study examined sleep patterns among Slovak adolescents to see how these relate to body fat and fitness levels.
  • Using data from over 8,900 young people, researchers identified three sleep groups: optimal sleepers, those with occasional sleep issues, and poor sleepers.
  • Findings revealed that poor sleepers had more body fat and lower fitness; however, only the link to fitness remained significant after further analysis, suggesting these insights could inform health interventions for teens.

Fixation patterns in pairs of facial expressions-preferences of self-critical individuals.

PeerJ Comput Sci

November 2024

Institute of Applied Psychology, Faculty of Social and Economic Sciences, Comenius University, Bratislava, Slovakia.

So far, studies have revealed some differences in how long self-critical individuals fixate on specific facial expressions and difficulties in recognising these expressions. However, the research has also indicated a need to distinguish between the different forms of self-criticism (inadequate or hated self), the key underlying factor in psychopathology. Therefore, the aim of the current research was to explore fixation patterns for all seven primary emotions (happiness, sadness, fear, disgust, contempt, anger, and surprise) and the neutral face expression in relation to level of self-criticism by presenting random facial stimuli in the right or left visual field.

Background: Formula-fed preterm infants require nutrient-enriched formulas with optimized protein levels to support growth and neurodevelopment. The purpose of this study was to evaluate the safety, tolerability, and effectiveness of a new liquid two-staged formula system designed to provide tailored nutrition during hospital stay and after discharge.

Methods: Male and female very-low-birth-weight preterm infants (birth weight ≤1,500 g; gestational age ≤32 weeks) were recruited from three neonatal units in Poland and Slovakia in a prospective, open-label, interventional study.

Cystic partially differentiated nephroblastoma (CPDN) is a rare pediatric renal tumor composed of multiple cystic spaces divided by septa containing immature nephrogenic elements. The presence of expansile solid areas in the septa of such a lesion indicates an alternative diagnosis of Wilms tumor (WT). We present a unique case of CPDN associated with grossly visible polypoid proliferations, which histologically correspond to botryoid growth of intralobar nephrogenic rests.

Article Synopsis
  • The genus Vitisma, described by Vršanský in 1999, features unique physical traits like a convex pronotum, sclerotized forewings, and simplified venation patterns.
  • The hindwing structure resembles that of the Blattulidae family, with specific characteristics like a distinct pterostigma and a comb-like R1 vein.
  • The discovery of Vitisma coriacea in Burmese amber indicates a broader historical distribution across Gondwana and suggests these insects thrived in warm, tropical forest environments.
