CellKine clinical trial: first report from a phase 1 trial of allogeneic bone marrow-derived mesenchymal stem cells in subjects with painful lumbar facet joint arthropathy.

Background: Lumbar facet joint arthropathy (LFJA) is a major cause of low back pain (LBP), with current treatments offering limited long-term benefits. Bone marrow-derived mesenchymal stem cells (BM-MSCs) show promise due to their immunomodulatory and trophic effects, potentially addressing underlying degenerative processes in LFJA.

Objectives: This initial report describes the outcomes of the first treated patient in an ongoing mutidisciplinary phase 1 clinical trial evaluating the safety and feasibility of intra-articular allogeneic BM-MSCs for painful LFJA.

Association between genes and susceptibility to inflammatory bowel disease: An updated meta-analysis.

Background: Several studies have associated members of the genes as susceptibility factors to inflammatory bowel diseases (IBD): ulcerative colitis (UC) and Crohn's disease (CD).

Objectives: To assess the association between the presence and absence genes and IBD susceptibility through a meta-analysis.

Method: A systematic search was performed through the PubMed, Scopus, and Web of Science databases to obtain relevant articles published before March 2024.

Response-dependent point loss and response force as disrupting operations on behavioral resistance to change in humans.

Behavioral momentum theory (BMT) provides a theoretical and methodological framework for understanding how differentially maintained operant responding resists disruption. A common way to test operant resistance involves contingencies with suppressive effects, such as extinction or prefeeding. Other contingencies with known suppressive effects, such as response-cost procedures arranged as point-loss or increases in response force, remain untested as disruptive events within the BMT framework.

Abscisic Acid: A Potential Secreted Effector Synthesized by Phytophagous Insects for Host-Plant Manipulation.

Abscisic acid (ABA) is an isoprenoid-derived plant signaling molecule involved in a wide variety of plant processes, including facets of growth and development as well as responses to abiotic and biotic stress. ABA had previously been reported in a wide variety of animals, including insects and humans. We used high-performance liquid chromatography-electrospray ionization tandem mass spectrometry (HPLC-(ESI)-MS/MS) to examine concentrations of ABA in 17 species of phytophagous insects, including gall- and non-gall-inducing species from all insect orders with species known to induce plant galls: Thysanoptera, Hemiptera, Lepidoptera, Coleoptera, Diptera, and Hymenoptera.

Extracorporeal Membrane Oxygenation (ECMO) Training Program in A Pediatric Cardiac Intensive Care Unit: An 8-Year Single-Center Experience in Argentina.

Introduction: Extracorporeal membrane oxygenation (ECMO) for temporary cardiopulmonary support is one of the most intense and technologically complex therapies offered in medicine. It is a high-risk procedure that requires specific knowledge and technical skills to perform it with good results.

Objective: The main goal of this study is to describe our extracorporeal membrane oxygenation (ECMO) training program based on the study of specialized nurses and physicians of a simulation teaching experience, conducted in a pediatric cardiac intensive care unit.
