Management of intracranial hypertension with and without invasive intracranial pressure monitoring.

Management of intracranial hypertension (IH) has improved in the last decades driven by advancements in monitoring technologies and a deeper understanding of its pathophysiology. Although intracranial pressure (ICP) catheters are still recommended by current guidelines for monitoring patients at risk of IH, these methods are not without limitations. Challenges include procedural complications, availability of these devices in many healthcare settings and technical issues.

Lactate-coated polyurea-siRNA dendriplex: a gene therapy-directed and metabolism-based strategy to impair glioblastoma (GBM).

Glioblastoma (GBM) is a highly lethal disease with limited treatment options due to its infiltrative nature and the lack of efficient therapy able to cross the protective blood-brain barrier (BBB). GBMs are metabolically characterized by increased glycolysis and glutamine dependence. This study explores a novel metabolism-based therapeutic approach using a polyurea generation 4 dendrimer (PURE) surface functionalized with lactate (LA) (PURE-LA), to take advantage of glucose-dependent monocarboxylate transporters (MCTs) overexpression, loaded with selenium-chrysin (SeChry) and temozolomide (TMZ) or complexed with anti-glutaminase (GLS1) siRNAs to abrogate glutamine dependence.

CCL2 expression predicts clinical outcomes and regulates E-cadherin and angiogenesis in pituitary tumours.

The crosstalk between tumour cells and microenvironment components in pituitary neuroendocrine tumours (PitNETs), including chemokines, may impact tumour behaviour and clinical outcomes. CCL2 was previously identified as a key chemokine in PitNETs, but its role remains unknown. We aimed to study the role of CCL2 in defining the phenotype and clinical outcomes of PitNETs and in regulating macrophage chemotaxis, epithelial-to-mesenchymal transition (EMT) and angiogenesis.

Assessing the impact of TiO nanomaterials on intestinal cells: New evidence for epithelial translocation and potential pro-inflammatory effects.

Understanding the potential impact of nanomaterials (NMs) on human health requires further investigation into the organ-specific nano-bio interplay at the cellular and molecular levels. We showed increased chromosomal damage in intestinal cells exposed to some of in vitro digested Titanium dioxide (TiO) NMs. The present study aimed to explore possible mechanisms linked to the uptake, epithelial barrier integrity, cellular trafficking, as well as activation of pro-inflammatory pathways, after exposure to three TiO-NMs (NM-102, NM-103, and NM-105).

Alternative Splicing at the Crossroad of Inflammatory Bowel Diseases and Colitis-Associated Colon Cancer.

The risk of developing colorectal cancer (CRC) is increased in ulcerative colitis patients compared to the general population. This increased risk results from the state of chronic inflammation, a well-known tumour-promoting condition. This review explores the pathologic and molecular characteristics of colitis-associated colon cancer (CAC), emphasizing the distinct features from sporadic CRC.

Hemosporidian infection in free-living Cathartes aura (Linnaeus, 1758) in the Amazon biome, Pará State, Brazil: Parasitological, molecular, hematological, and biochemical analyses.

Hemosporidians are intracellular pathogens that infect a range of endothermic and ectothermic hosts and are transmitted by dipteran vectors. These parasites are grouped into four families: Haemoproteidae, Plasmodiidae, Leucocytozoidae, and Garniidae, with the genera Haemoproteus, Plasmodium, and Leucocytozoon being the most common in birds. Therefore, the objectives of this study were to detect the infection frequency of hemosporidians and to perform hematological and biochemical analyses in free-living turkey vultures (Cathartes aura) in the Amazon biome, Brazil.

Iatrogenic intramural esophageal hematoma during EUS-B-FNA procedure.

Background: Esophageal ultrasound with bronchoscope fine needle aspiration (EUS-B-FNA) is a valuable tool for the diagnosis and staging of lung cancer, complementing endobronchial lung ultrasound (EBUS). While generally considered safe, there is a notable lack of comprehensive knowledge within the interventional pulmonology community regarding potential complications.

Case Presentation: We present a case involving a 66-year-old male with squamous cell lung carcinoma undergoing mediastinal staging.

A Solution to Prevent and Minimize the Consequences of Accidents with Farm Tractors in the Context of Mountainous Regions with Low Population Density.

Farm tractors have become a key part of daily routine agriculture, converting complex and time-consuming tasks into tasks that are easier to perform and less dependent on human labor, contributing directly to increasing the economic value generated by this activity sector, either by increasing the productivity or by making certain agricultural crops viable, which otherwise would not be sustainable. However, despite all the advantages, accidents with this type of equipment are common, often with critical and sometimes fatal consequences. The evolution of safety requirements of these machines has occurred at a good level; however, a significant part of the agricultural tractors in use are older models that do not have such solutions.

YES1 Kinase Mediates the Membrane Removal of Rescued F508del-CFTR in Airway Cells by Promoting MAPK Pathway Activation via SHC1.

Recent developments in CFTR modulator drugs have had a significant transformational effect on the treatment of individuals with Cystic Fibrosis (CF) who carry the most frequent F508del-CFTR mutation in at least one allele. However, the clinical effects of these revolutionary drugs remain limited by their inability to fully restore the plasma membrane (PM) stability of the rescued mutant channels. Here, we shed new light on the molecular mechanisms behind the reduced half-life of rescued F508del-CFTR at the PM of airway cells.

DIS3L2 knockdown impairs key oncogenic properties of colorectal cancer cells via the mTOR signaling pathway.

DIS3L2 degrades different types of RNAs in an exosome-independent manner including mRNAs and several types of non-coding RNAs. DIS3L2-mediated degradation is preceded by the addition of nontemplated uridines at the 3'end of its targets by the terminal uridylyl transferases 4 and 7. Most of the literature that concerns DIS3L2 characterizes its involvement in several RNA degradation pathways, however, there is some evidence that its dysregulated activity may contribute to cancer development.

Evaluating the Feasibility of Using Brick Powder and Clay Powder in Cement Replacement.

The cement industry generates very large amounts of CO into the atmosphere. In recent years, there has been a search for alternative cementitious materials and micro-fillers that could partially or fully replace cement in cement composites without compromising their durability. This paper investigates the possibility of using brick powder (BP) and clay powder (CP) as a partial replacement for cement (up to 20% by weight) in cement paste.

Adherens Junction Integrity Is a Critical Determinant of Sodium Iodide Symporter Residency at the Plasma Membrane of Thyroid Cells.

While most cases of differentiated thyroid carcinoma (DTC) are associated with a good prognosis, a significant number progress to advanced disease exhibiting aggressive clinical characteristics and often becoming refractory to radioactive iodine (RAI) treatment, the current gold-standard therapeutic option for metastatic disease. RAI-refractoriness is caused by defective functional expression of the sodium-iodide symporter (NIS), which is responsible for the active transport of iodide across the plasma membrane (PM) into thyroid follicles. NIS deficiency in these tumors often reflects a transcriptional impairment, but also its defective targeting and retention at the cells' PM.

Adverse Outcome Pathways Associated with the Ingestion of Titanium Dioxide Nanoparticles-A Systematic Review.

Recycled Aggregate: A Viable Solution for Sustainable Concrete Production.

Construction and demolition activities consume large amounts of natural resources, generating 4.5 bi tons of solid waste/year, called construction and demolition waste (C&DW) and other wastes, such as ceramic, polyethylene terephthalate (PET), glass, and slag. Furthermore, around 32 bi tons of natural aggregate (NA) are extracted annually.

Effect of TiO Nanoparticles on the Fresh Performance of 3D-Printed Cementitious Materials.

3D printing (3DP) of cementitious materials shows several advantages compared to conventional construction methods, but it requires specific fresh-state properties. Nanomaterials have been used in cement-based materials to achieve specific fresh and hardened properties, being potential candidates for 3DP applications. However, there are no reports on using TiO2 nanoparticles (nano-TiO2) in 3DP cementitious composites.
