Light-driven molecular rotary motors are nanometric machines able to convert light into unidirectional motions. Several types of molecular motors have been developed to better respond to light stimuli, opening new avenues for developing smart materials ranging from nanomedicine to robotics. They have great importance in the scientific research across various disciplines, but a detailed comprehension of the underlying ultrafast photophysics immediately after photo-excitation, that is, Franck-Condon region characterization, is not fully achieved yet.

Distinguishing tumours from other conditions is a primary challenge in paediatric neuro-radiology. This paper aims to describe mimics, which are non-neoplastic conditions that have features similar to a neoplastic process caused by a non-neoplastic entity, and chameleons, which are uncommon presentations of brain tumours that are mistaken for other diagnoses. By doing so, we aim to raise awareness of these conditions and prevent inappropriate investigations or treatment in children.

According to the FAO/WHO guidelines, selection of probiotics requires the assessment of survival under gastrointestinal stress and adhesion to human epithelial cells. These attributes were evaluated on ATCC BAA-835 simulating the gastrointestinal transit (GIT) immediately followed by adhesion to human intestinal cell lines (CaCo2, HT-29, and HT-29-MTX) as an alternative approach to methods performed with fresh cells in each trial. The survival rate after GIT, as determined by plate counts and fluorescent probes, was significantly higher for (about 8 Log CFU/mL) than for the probiotic GG ATCC 53103 (about 3 Log CFU/mL).

Article Synopsis
  • * Two fat replacers, lemon albedo and carob seed gum, were analyzed for their effects on the burgers, along with plant extracts from nettle leaves and medlar seeds that were tested for antimicrobial and antioxidant properties.
  • * Results showed that while the fat replacers improved nutrition and taste, they did not guarantee safety, indicating that combining them with natural antimicrobial extracts, like medlar seeds, is crucial for producing safe low-fat burgers.

Many viruses initiate their cell-entry by binding their multisubunit receptors to human heparan sulfate proteoglycans (HSPG) and other molecular components present on cellular membranes. These viral interactions could be blocked and the whole viruses could be eliminated by suitable HSPG-mimetics providing multivalent binding to viral protein receptors. Here, large sulfoglycodendron HSPG-mimetics of different topologies, structures, and sizes were designed to this purpose.

A single strain of yeast was isolated from industrial gluten bread (GB) purchased from a local supermarket. This strain is responsible for spoilage consisting of white powdery and filamentous colonies due to the fragmentation of hyphae into short lengths (dust-type spots), similar to the spoilage produced by chalk yeasts such as , and . The isolated strains were identified initially by traditional methods as , but with genomic analysis, they were definitively identified as , a rare ascomycetous opportunistic yeast species with low virulence attributes, uncommonly implicated in bread spoilage.

The differential diagnosis of supratentorial brain tumours in children can be challenging, especially considering the recent changes to the WHO classification of CNS tumours published in 2021. Many new tumour types have been proposed which frequently present in children and young adults and their imaging features are currently being described by the neuroradiology community. The purpose of this article is to provide guidance to residents and fellows new to the field of paediatric neuroradiology on how to evaluate an MRI of a patient with a newly diagnosed supratentorial tumour.

Article Synopsis
  • Researchers studied spoiled cooked sausages with yellow stains to identify the microbial cause and test antimicrobials to prevent spoilage.
  • They found that a specific bacteria was responsible for the yellow coating and that this bacteria thrived in the presence of cooked sausage extract, producing volatile compounds typical of spoilage.
  • While several antimicrobials slowed the bacteria's growth, only hop extract completely inhibited it without affecting the sausages' taste, marking a new finding in antimicrobial research.

Article Synopsis
  • Pharmaceuticals like caffeine (CAF) enter aquatic ecosystems mainly through wastewater and hospital waste, raising concerns about their environmental impact, especially under rising temperatures caused by climate change.
  • The study used the mussel Mytilus galloprovincialis to examine the toxicity of different CAF concentrations at 17 °C and 21 °C, observing subcellular effects over 28 days.
  • Findings revealed that higher CAF levels at 17 °C increased metabolism and caused cellular damage, while at 21 °C, the mussels showed antioxidant enzyme induction but still suffered from cellular damage, with a synergistic negative effect when CAF exposure and temperature rise occurred together.

  • The study evaluated the effectiveness of fibrin glue versus traditional neurorrhaphy for repairing small nerve gaps in male Wistar rats.
  • In the experiment, a 15 mm defect was created in the sciatic nerve of the rats, which were divided into two groups: one receiving standard suturing and the other using fibrin glue.
  • Results showed no significant differences between the two methods, except for a slight improvement in the muscle motor units of the group using fibrin glue, suggesting that while not superior, the glue method could be a faster and easier option for clinical use.

Oxygen (O) supply is constantly maintained by the vascular network for a proper tissue oxygenation. Hypoxia is the result of an increased O demand and/or decreased supply and is common in both physiological conditions and human diseases. Angiogenesis is one of the adaptive responses to hypoxia and is mainly regulated by the hypoxia-inducible factors, HIFs.

Melanoma is the principal cause of death in skin cancer due to its ability to invade and cause metastasis. Hypoxia, which characterises the tumour microenvironment (TME), plays an important role in melanoma development, as cancer cells can adapt and acquire a more aggressive phenotype. Carbonic anhydrases (CA) activity, involved in pH regulation, is related to melanoma cell migration and invasion.

Modern, nonlinear, time-resolved spectroscopic techniques have opened new doors for investigating the intriguing but complex world of photoinduced ultrafast out-of-equilibrium phenomena and charge dynamics. The interaction between light and matter introduces an additional dimension, where the complex interplay between electronic and vibrational dynamics needs the most advanced theoretical-computational protocols to be fully understood on the molecular scale. In this study, we showcase the capabilities of ab initio molecular dynamics simulation integrated with a multiresolution wavelet protocol to carefully investigate the excited-state relaxation dynamics in a noncovalent complex involving tetramethylbenzene (TMB) and tetracyanoquinodimethane (TCNQ) undergoing charge transfer (CT) upon photoexcitation.
