PEGylated Platinum Nanoparticles: A Comprehensive Study of Their Analgesic and Anti-Inflammatory Effects.

Pain and inflammation are common symptoms of a majority of the diseases. Chronic pain and inflammation, as well as related dreadful disorders, remain difficult to control due to a lack of safe and effective medications. In this work, biocompatible platinum nanoparticles with significant analgesic and anti-inflammatory action were synthesized through a wet chemical method using polyethylene glycol-400 as a capping agent and sodium borohydride as a reducing agent.

Ampullary composite gangliocytoma/neuroma and neuroendocrine tumor management.

Ampullary composite gangliocytoma/neuroma and neuroendocrine tumor (CoGNET), previously called ampullary gangliocytic paragangliomas (GP) are a rare entity, with only few reported cases in the literature. This is a multicentric retrospective cohort of patients treated with endoscopy or surgery for ampullary CoGNET. A literature review of ampullary CoGNET was also performed.

Biotechnological advances in plant growth-promoting rhizobacteria for sustainable agriculture.

The rhizosphere, the soil zone surrounding plant roots, serves as a reservoir for numerous beneficial microorganisms that enhance plant productivity and crop yield, with substantial potential for application as biofertilizers. These microbes play critical roles in ecological processes such as nutrient recycling, organic matter decomposition, and mineralization. Plant growth-promoting rhizobacteria (PGPR) represent a promising tool for sustainable agriculture, enabling green management of crop health and growth, being eco-friendly alternatives to replace chemical fertilizers and pesticides.

Impact of gender on self-assessment accuracy among fourth-year French medical students on faculty's online Objective Structured Clinical Examinations.

Background: Historically, women have been shown to underestimate their abilities, while men often assess themselves more accurately or overestimate. This study aims to determine self-assessment accuracy during online Objective Structured Clinical Examinations (OSCEs) according to gender.

Methods: A prospective study was conducted among fourth-year medical students at Paris Cité University during faculty training OSCEs, utilizing Zoom® software for remote participation.

Reinforcement and characterization of biopolymer-rhamnolipid nanoparticles: Biocompatibility, in-vitro stability, physico-chemical, rheological and bioactive properties.

In the present study, biopolymer (chitosan and alginate)-reinforced rhamnolipid nanoparticles were prepared and represented as 'ALG-RHLP-NPs' and 'CHI-RHLP-NPs'. The sizes of the nanoparticles ranged from 150 to 300 nm. The encapsulation efficiencies of ALG-RHLP-NPs and CHI-RHLP-NPs were found to be 81.

CD57 EMRA CD8 T cells in cancer patients over 70: associations with prior chemotherapy and response to anti-PD-1/PD-L1 therapy.

Background: Immune ageing complicates cancer treatment in older individuals. While immunotherapy targeting the PD-1/PD-L1 pathway can reinvigorate T cells, these cells tend to become senescent with age. This study investigates different CD8 T cell subsets usually associated with senescence, in cancer patients over 70 years old who are undergoing anti-PD-1/PD-L1 immunotherapy, and examines the relationship between these senescent cells and prior chemotherapy exposure.

Nitazoxanide controls virus viability through its impact on membrane bioenergetics.

Viruses are dependent on cellular energy metabolism for their replication, and the drug nitazoxanide (Alinia) was shown to interfere with both processes. Nitazoxanide is an uncoupler of mitochondrial oxidative phosphorylation (OXPHOS). Our hypothesis was that mitochondrial uncoupling underlies the antiviral effects of nitazoxanide.

Upregulation of haematopoetic cell kinase (Hck) activity by a secreted parasite effector protein (Ta9) drives proliferation of Theileria annulata-transformed leukocytes.

Reversible transformation of bovine leukocytes by the intracellular parasites Theileria annulata and Theileria parva is central to pathogenesis of the diseases they cause, tropical theileriosis and East Coast Fever, respectively. Parasite-dependent constitutive activation of major host transcription factors such as AP-1 (Activating Protein 1) and NF-κB (Nuclear Factor-Kappa B) sustains the transformed state. Although parasite interaction with host cell signaling pathways upstream of AP-1 have been studied, the precise contribution of Theileria encoded factors capable of modulating AP-1 transcriptional activity, and other infection-altered signaling pathways is not fully understood.

Association between emergency medical services' response times, low socioeconomic status, and poorer outcomes in out-of-hospital cardiac arrest: the MEDIC multicenter retrospective cohort study for disparities in access to prehospital critical care in the Paris metropolitan area.

Background And Importance: Prolonged emergency medical services' response times (EMS-RT) are associated with poorer outcomes in out-of-hospital cardiac arrest (OHCA). The patient access time interval (PATI), from vehicle stop until contact with patient, may be increased in areas with low socioeconomic status (SES).

Objectives: The objective of this study is to identify predictors of prolonged EMS-RT intervals, and to evaluate associations with clinical outcomes in OHCAs occurring in the largest metropolitan area in France.

Molecular features and expression kinetics of interleukin-10 gene from the marine teleost, Snubnose pompano (Trachinotus blochii).

Background: Interleukin 10 (IL-10) is uniquely positioned in the immune regulation of teleosts. Modifying the IL-10 pathway changes the teleost's disease susceptibility; however, there is no data on its post-transcriptional regulation. Trachinotus blochii is a high-value mariculture species.

Hypoglycaemic stimulation of macrophage cytokine release is suppressed by AMP-activated protein kinase activation.

Aims: Acute hypoglycaemia promotes pro-inflammatory cytokine production, increasing the risk for cardiovascular events in diabetes. AMP-activated protein kinase (AMPK) is regulated by and influences the production of pro-inflammatory cytokines. We sought to examine the mechanistic role of AMPK in low glucose-induced changes in the pro-inflammatory cytokine macrophage migration inhibitory factor (MIF), which is elevated in people with diabetes.

The current study reports the synthesis and characterization of bacterial cellulose from a novel microbial consortium of Weissela confusa, Neobacillus drentensis, and Bacillus sp. isolated from mother of vinegar and identified by 16S rDNA typing.

The First Lugano Workshop on the role of adenomyosis in ART.

Adenomyosis is an important clinical condition with uncertain prevalence, and clinical focus on adenomyosis in patients undergoing assisted reproductive technology (ART) has increased during recent years. Recognizing the limited clinical knowledge on the impact of adenomyosis on ART outcomes, the First Lugano Adenomyosis Workshop was a symposium involving experts in the field of adenomyosis, covering basic research, imaging, surgery and infertility to highlight current advances and future research areas over a wide range of topics related to adenomyosis. Adenomyosis is characterized by altered oestrogen and progesterone signalling pathways.

Differential HBV RNA and HBcrAg patterns in untreated patients with chronic hepatitis delta.

Background And Aim: Serum HBV RNA and HBcrAg levels have been proposed as useful biomarkers in the management of HBV patients, however their role in chronic hepatitis Delta (CHD) is currently unknown.

Methods: Consecutive untreated CHD patients were enrolled in a cross-sectional study in three EU centers. Clinical and virological characteristics were collected.

Spectroscopic Investigation of Hydrogels Formed from Phenylalanine.

Supramolecular hydrogels assembled from amino acids, particularly offer promising prospects as biomimetic three-dimensional extracellular matrices. Phenylalanine, an aromatic amino acid, can self-assemble via hydrophobic interactions, notably through 𝜋 - 𝜋 stacking between phenyl rings. Although the self-assembly processes have been studied, the gelation mechanism of phenylalanine as an individual amino acid has received limited attention in the literature.
