Nutrients

May 2024

Department of Child and Adolescent Psychiatry, Psychosomatics and Psychotherapy, LVR University Hospital Essen, Virchowstrasse 174, 45147 Essen, Germany.

Anorexia nervosa (AN) is a severe eating disorder that predominantly affects females and typically manifests during adolescence. There is increasing evidence that serum cytokine levels are altered in individuals with AN. Previous research has largely focused on adult patients, assuming a low-grade pro-inflammatory state.

The lesson from many studies investigating the efficacy of targeted therapy in glioblastoma (GBM) showed that a future perspective should be focused on combining multiple target treatments. Our research aimed to assess the efficacy of drug combinations against glioblastoma stem cells (GSCs). Patient-derived cells U3042, U3009, and U3039 were obtained from the Human Glioblastoma Cell Culture resource.

Article Synopsis
  • - Researchers investigated the potential link between autoimmunity and spontaneous cervical artery dissection (sCAD) by analyzing anti-collagen type I antibodies in various patient groups, including those with sCAD, ischemic stroke, and healthy controls.
  • - A total of 57 sCAD patients were studied alongside control groups, with findings showing that while sCAD patients had higher antibody levels compared to healthy subjects, they had lower levels than those with unrelated ischemic strokes.
  • - The study concluded that elevated levels of anti-collagen type I antibodies in sCAD patients are not a direct trigger for the condition but may relate to the metabolism and turnover of collagen type I.

Despite continuous and rapid progress in the transplantation of cells, tissues, and organs, many patients die before receiving them. This is because of an insufficient number of donors, which leads to a significant disproportion between the need for donors and their availability. This review aims to present the possibilities offered by alternative therapies.

Clinic of Nephrology and Hypertension, Diabetes and Endocrinology, Otto-von-Guericke University Magdeburg, Magdeburg, Germany; Health Campus Immunology, Infectiology and Inflammation (GCI3), Otto-von-Guericke University Magdeburg, Magdeburg, Germany. Electronic address:

Article Synopsis
  • DbpA (Ybx3) is part of the cold shock protein family and is involved in various cellular functions, with its role in acute kidney injury (specifically ischemia/reperfusion injury) being unclear.
  • Research involving genetically modified mice showed that DbpA is not essential for kidney health but its deletion enhances mitochondrial performance and protects against IRI by reducing cell damage and immune response.
  • The findings suggest that targeting DbpA could be beneficial in preventing kidney damage during surgeries like transplantation or cardiac procedures by improving mitochondrial function and reducing harmful cell processes.

LIFE Child Study, University Hospital for Children and Adolescents, Medical Faculty, Leipzig University, Philipp-Rosenthal-Strasse 27, 04103 Leipzig, Germany; Department of Women and Child Health, University Hospital for Children and Adolescents, Leipzig University, Liebigstrasse 20a, 04103 Leipzig, Germany; Center for Pediatric Research (CPL), University Hospital for Children and Adolescents, Leipzig University, Liebigstrasse 20a, 04103 Leipzig, Germany.

Background: Creatine Kinase (CK) has become increasingly important in pediatrics as a commonly used laboratory screening parameter for neuromuscular diseases. Recent research suggests that hyperCKemia in children is not always associated with pathology and can occur due to several reasons. Little is known of various clinical factors that may influence CK throughout child development.

Human Vault RNAs: Exploring Their Potential Role in Cellular Metabolism.

Int J Mol Sci

April 2024

Department of Clinical Chemistry and Molecular Diagnostics, Poznan University of Medical Sciences, Rokietnicka 3, 60-806 Poznan, Poland.

Non-coding RNAs have been described as crucial regulators of gene expression and guards of cellular homeostasis. Some recent papers focused on vault RNAs, one of the classes of non-coding RNA, and their role in cell proliferation, tumorigenesis, apoptosis, cancer response to therapy, and autophagy, which makes them potential therapy targets in oncology. In the human genome, four vault RNA paralogues can be distinguished.

The BMI predicts mortality and cardiovascular disease (CVD) in the general population, while in patients with end-stage chronic kidney disease (CKD) a high BMI is associated with improved survival, a phenomenon referred to as the "obesity paradox". While BMI is easy to determine and helps to categorize patients, it does not differentiate between fat tissue, lean tissue and bone mass. As the BMI may be altered in CKD, e.

Background: Viral meningitis/encephalitis (ME) is a rare but potentially harmful disease. The prompt identification of the respective virus is important to guide not only treatment but also potential public health countermeasures. However, in about 40% of cases, no virus is identified despite an extensive diagnostic workup.

  • PCSK9 is important in lipid metabolism, with higher levels in women throughout their lives, and statin treatment influences these levels with potential genetic variances affecting results by sex.* -
  • The study involved meta-analyses of PCSK9 levels in over 14,000 individuals, analyzing the effects of both sex and statin treatment on genetic associations related to PCSK9 and LDL cholesterol levels.* -
  • Results highlighted 11 genetic loci linked to PCSK9, with some showing different effects based on sex and statin status, including novel associations for specific groups; this suggests distinct genetic influences on cholesterol levels based on gender and medication use.*

The Minimum Information About BIobank Data Sharing (MIABIS) is a biobank-specific terminology enabling the sharing of biobank-related data for different purposes across a wide range of database implementations. After 4 years in use and with the first version of the individual-level MIABIS component , and , it was necessary to revise the terminology, especially to include biobanks that work more in the data domain than with samples. Nine use-cases representing different types of biobanks, studies, and networks participated in the development work.

The role of endoplasmic reticulum-mitochondria-associated membranes in diabetic kidney disease.

Cardiovasc Res

February 2024

Institute of Laboratory Medicine, Clinical Chemistry and Molecular Diagnostics, University Hospital Leipzig, Paul-List-Straße 13/15, 04103 Leipzig, Germany.

Diabetic kidney disease (DKD) is the leading cause of end-stage renal disease worldwide. The pathomechanisms of DKD are multifactorial, yet haemodynamic and metabolic changes in the early stages of the disease appear to predispose towards irreversible functional loss and histopathological changes. Recent studies highlight the importance of endoplasmic reticulum-mitochondria-associated membranes (ER-MAMs), structures conveying important cellular homeostatic and metabolic effects, in the pathology of DKD.

B-cell maturation antigen (BCMA)-targeting chimeric antigen receptor (CAR) T cells revolutionized the treatment of relapsed/refractory multiple myeloma (RRMM). However, data on cellular (CAR) T cell dynamics and the association with response, resistance or the occurrence of cytokine release syndrome (CRS) are limited. Therefore, we performed a comprehensive flow cytometry analysis of 27 RRMM patients treated with Idecabtagene vicleucel (Ide-cel) to assess the expansion capacity, persistence and effects on bystander cells of BCMA-targeting CAR T cells.
