Objective: In the authors' experience, extended superficial-thickness wounds often were treated with the application of synthetic temporary wound dressings. There is a broad range of expensive products available in this market. The aim of this study was to compare commonly used temporary skin dressings with a newly developed collagen matrix.
Methods: A total of 56 standardized superficial skin defects were generated on the back of 28 adult male Lewis rats using a skin dermatome. The wounds were treated with Biobrane (Smith & Nephew, St Petersburg, Florida) (n = 14), Suprathel (PolyMedics, Denkendorf, Germany) (n = 14), and newly developed Collagen Cell Carrier (Naturin Viscofan, Weinheim, Germany) (CCC; n = 14). Histological evaluation was performed at 3 months' postoperative in regard to quality of newly formed skin.
Results: In regard to epidermal cell count and thickness of skin, Biobrane and Suprathel demonstrated comparable values, whereas CCC demonstrated higher epidermal cell count and thicker neoepidermis. The epidermal thickness of CCC was comparable to untreated, healthy skin.
Conclusions: The presented results reveal the potential of CCC in the treatment of superficial skin defects and encourages further evaluation of CCC in surgical applications and regenerative medicine.

Unlabelled: Minimal residual disease (MRD) is the most important prognostic factor for B-cell acute lymphoblastic leukemia (B-ALL) however nearly 20-30% of patients relapsed even when they achieved negative MRD, how to identify these patients is less addressed. In this study, we aimed to reassess the prognostic significance of MRD and IKZF1 in adult B-ALL patients receiving pediatric chemotherapy regimens. In the PDT-ALL-2016 cohort (NCT03564470), adult B-ALL patients were treated with a pediatric-inspired regimen; patients were redefined as standard (MRD-negative and IKZF1wild-type), intermediate (MRD-positive or IKZF1 deletion), and high-risk (MRD-positive and IKZF1 deletion) groups by combining IKZF1 deletion status and MRD.

Small nucleolar RNA host gene 10 (SNHG10) is a newly recognized long non-coding RNA (lncRNA) with significant implications in cancer biology. Abnormal expression of SNHG10 has been observed in various solid tumors and hematological malignancies. Research conducted in vivo and in vitro has revealed that SNHG10 plays a pivotal role in numerous biological processes, including cell proliferation, apoptosis, invasion and migration, drug resistance, energy metabolism, immune evasion, as well as tumor growth and metastasis.

Parkinson's disease (PD) is a neurodegenerative disease primarily affecting the central nervous system and impacting both the motor system and non-motor systems. Although administration of L-DOPA is effective, it is not a fundamental treatment and has side effects such as diurnal fluctuation and dyskinesia, highlighting the need for new treatment methods. There is a growing interest in dopaminergic neuron transplantation as a potential treatment.

In the 11th version of the WHO´s International Classification of Diseases, complex post-traumatic stress disorder (CPTSD) is newly recognized as a variant of PTSD, characterized by additional and more severe symptoms and typically arising from prolonged or multiple traumatic experiences. Despite recent research supporting the differentiation between PTSD and CPTSD, studies also identify a third or even a fourth latent profile in trauma patients. This study employs latent profile analysis to identify the number of latent profiles within a clinical trauma population in Germany (N = 588) and aims to investigate their distinct symptomatology.
