Pan-cancer and multiomics: advanced strategies for diagnosis, prognosis, and therapy in the complex genetic and molecular universe of cancer.

The pan-cancer and multi-omics approach is motivated by the genetic and molecular complexity inherent in the varied types of cancer. This method presents itself as a crucial resource for advancing early diagnosis, defining prognoses and identifying treatments that share common bases between different forms of tumors. The aim of this article is to explore pan-cancer analysis in conjunction with multi-omics strategies, evaluating laboratory, computational, clinical procedures and their consequences, as well as examining the tumor microenvironment, epigenetics and future directions of these technologies in patient management.

Characterization and analysis of the bioactivity of the Piper rivinoides Kunth essential oil and its components myristicin and elemicin, against opportunistic fungal pathogens.

Candidiasis is an infectious disease caused by some fungi of the genus Candida. In Brazil, the incidence rate is higher than in European countries and the United States, and health problems occur mainly due to the virulence factors of the fungi, which have made treatment with commercial drugs difficult. Considering the context, plants rich in phenolic compounds, such as those of the genus Piper, have been studied due to their antimicrobial properties.

Time domain NMR for polymorphism characterization: Current status and future perspectives.

Polymorphism is the ability of a compound to exist in multiple crystal forms while maintaining the same chemical composition. This phenomenon is reflected in different solid-state physicochemical properties due to variations in structural energy and the degree of lattice disorder. The pharmaceutical industry places significant emphasis on thoroughly characterizing polymorphism in Active Pharmaceutical Ingredients (APIs) because of its impact on the pharmacokinetic properties on the final medicine product.

The Escherichia coli TolC efflux pump protein is immunogenic and elicits protective antibodies.

Antimicrobial resistance is an increasing worldwide public health burden that threatens to make existent antimicrobials obsolete. An important mechanism of antimicrobial resistance is the overexpression of efflux pumps, which reduce the intracellular concentration of antimicrobials. TolC is the outer membrane protein of an efflux pump that has gained attention as a therapeutic target.

Reviewing mathematical models of sperm signaling networks.

Classical and Nonclassical Nucleation Mechanisms of Insulin Crystals.

Although the (CNT) is the most consensual theory to explain protein nucleation mechanisms, experimental observations during the shear-induced assays suggest that the CNT does not always describe the insulin nucleation process. This is the case at intermediate precipitant (ZnCl) solution concentrations (2.3 mM) and high-temperature values (20 and 40 °C) as well as at low precipitant solution concentrations (1.

Depth Control of an Underwater Sensor Platform: Comparison between Variable Buoyancy and Propeller Actuated Devices.

Underwater long-endurance platforms are crucial for continuous oceanic observation, allowing for sustained data collection from a multitude of sensors deployed across diverse underwater environments. They extend mission durations, reduce maintenance needs, and significantly improve the efficiency and cost-effectiveness of oceanographic research endeavors. This paper investigates the closed-loop depth control of actuation systems employed in underwater vehicles, focusing on the energy consumption of two different mechanisms: variable buoyancy and propeller actuated devices.

Mechanistic insights into C(sp)-H activation in 1-Phenyl-4-vinyl-1H-1,2,3-triazole derivatives: a theoretical study with palladium acetate catalyst.

Context: The activation of C-H bonds is a fundamental process in synthetic organic chemistry, which enables their replacement by highly reactive functional groups. Coordination compounds serve as effective catalysts for this purpose, as they facilitate chemical transformations by interacting with C-H bonds. A comprehensive understanding of the mechanism of activation of this type of bond lays the foundation for the development of efficient protocols for cross-coupling reactions.

The changes in the energy sector after the Paris agreement and the establishment of the Green Deal, pressed the governments to embrace new measures to reduce greenhouse gas emissions. Among them, is the replacement of fossil fuels by renewable energy sources or carbon-neutral alternative means, such as green hydrogen. As the European Commission approved green hydrogen as a clean fuel, the interest in investments and dedicated action plans related to its production and storage has significantly increased.

Crescentic glomerulonephritis due to linear IgA anti-glomerular basement membrane disease: report of a rare case.

Anti-glomerular basement membrane (GBM) disease is a rare and severe vasculitis that affects the glomerular and pulmonary capillaries and has an incidence of less than 2 cases per million individuals per year. Anti-GBM disease is mediated by autoantibodies against the α3 chain of type IV collagen. In the majority of cases, the autoantibodies are of the immunoglobulin G (IgG) class, with rare cases being mediated by immunoglobulin M (IgM) or immunoglobulin A (IgA); there are less than 15 IgA-mediated cases reported in the literature worldwide.
