Background: In this study we investigated whether plasma level of IL-2 or sIL-2R shows the clinical disease status.
Material And Methods: Plasma levels of IL-2 and sIL-2R were measured by ELISA in 23 patients with limited scleroderma (1SSc-acrosclerosis) and compared with 12 healthy women.
Results: Plasma levels of sIL-2R in the group of patients with severe internal organs involvement (3446.1 +/- 1329.7 pg/ml) were significantly higher compared with those with minimal internal organs involvement (1606.4 +/- 507.3 pg/ml). Plasma level of IL-2 in the group of patients with severe internal organs involvement (8.12 +/- 7.77 pg/ml) did not differ much from that of the patients with minimal internal organs involvement (7.42 +/- 9.28 pg/ml). Treatment with pentoxyfilline did not influence the plasma levels of IL-2 and sIL-2R.
Conclusions: We concluded that elevated plasma levels of IL-2 and sIL-2R are markers of internal organ involvement in scleroderma.

Background: Enhancing self-management in health care through digital tools is a promising strategy to empower patients with type 2 diabetes (T2D) to improve self-care.
Objective: This study evaluates whether the Greenhabit (mobile health [mHealth]) behavioral treatment enhances T2D outcomes compared with standard care.
Methods: A 12-week, parallel, single-blind randomized controlled trial was conducted with 123 participants (62/123, 50%, female; mean age 58.

Purpose: The landiolol and organ failure in patients with septic shock (STRESS-L study) included a pre-planned sub-study to assess the effect of landiolol treatment on inflammatory and metabolomic markers.
Methods: Samples collected from 91 patients randomised to STRESS-L were profiled for immune and metabolomic markers. A panel of pro- and anti-inflammatory cytokines were measured through commercially acquired multiplex Luminex assays and statistically analysed by individual and cluster-level analysis (patient).

Immune and metabolic factors play an important role in the onset and development of insomnia. This study aimed to investigate the causal relationship between insomnia and immune cells and metabolites. Data for 731 immune cell phenotypes, 1400 metabolites, and insomnia in this study were obtained from the GWAS open-access database.

L-3,4-dihydroxyphenylalanine (L-DOPA) remains the main treatment for motor symptoms of Parkinson's disease (PD). However, chronic use is associated with the development of complications such as L-DOPA-induced dyskinesia. We previously demonstrated that LY-487,379, a highly selective metabotropic glutamate receptor 2 (mGluR2) positive allosteric modulator (PAM), reduces the severity of L-DOPA-induced abnormal involuntary movements (AIMs) in the 6-hydroxydopamine (6-OHDA)-lesioned rat model of PD, without interfering with the anti-parkinsonian action of L-DOPA.

Objectives: The objective of this study was to compare plasma glucagon-like peptide-2 (GLP-2) concentrations in cats with chronic enteropathies (CE) with those of healthy cats.
Methods: Nineteen client-owned cats with a histopathologic diagnosis of either idiopathic chronic enteropathy (CIE) or low-grade lymphoma and six healthy client-owned cats were enrolled in a prospective study between 2 December 2021 and 9 June 2023. Fasted and postprandial plasma GLP-2 concentrations were measured via ELISA in CE cats at the time gastrointestinal biopsies were obtained and before CE treatment.
