Assessing Nutritional Status in Gastric Cancer Patients after Total versus Subtotal Gastrectomy: Cross-Sectional Study.

Gastric cancer (GC) remains a significant global health concern, ranking as the third leading cause of cancer-related deaths. Malnutrition is common in GC patients and can negatively impact prognosis and quality of life. Understanding nutritional issues and their management is crucial for improving patient outcomes.

Understanding host-graft crosstalk for predicting the outcome of stem cell transplantation.

Mesenchymal stromal cells (MSCs) hold great promise for tissue regeneration in debilitating disorders. Despite reported improvements, the short-term outcomes of MSC transplantation, which is possibly linked to poor cell survival, demand extensive investigation. Disease-associated stress microenvironments further complicate outcomes.

Mesenchymal Stem Cell-Derived Exosomes Modulate Angiogenesis in Gastric Cancer.

Individualized gastric cancer (GC) treatment aims at providing targeted therapies that translate the latest research into improved management strategies. Extracellular vesicle microRNAs have been proposed as biomarkers for GC prognosis. infection influences the therapeutic response to and the drivers of malignant changes in chronic gastritis.

The mesocolic apical fragment in complete mesocolic excision colectomies: Should it be analysed separately? A proof-of-concept study.

Aim: The aim of this work is to describe a protocol and assess the feasibility of harvesting and analysing the mesocolic apical fragment (MAF) for the presence of central lymph node (LN) metastasis and extra lymphatic free tumour cells in a random subgroup extracted from a cohort of complete mesocolic excision colectomies with central vascular ligation.

Method: Forty-seven patients diagnosed with colorectal cancer were included. A 2/2 cm pyramid of tissue was cut around the central tie and sent for pathological examination.

NHF-derived carbon dots: prevalidation approach in breast cancer treatment.

Metastatic breast cancer dominates the female cancer-related mortality. Tumour-associated molecules represents a crucial for early disease detection and identification of novel therapeutic targets. Nanomaterial technologies provide promising novel approaches to disease diagnostics and therapeutics.

Long-Term Deleterious Effects of Short-term Hyperoxia on Cancer Progression-Is Brain-Derived Neurotrophic Factor an Important Mediator? An Experimental Study.

Perioperative factors promoting cancer recurrence and metastasis are under scrutiny. While oxygen toxicity is documented in several acute circumstances, its implication in tumor evolution is poorly understood. We investigated hyperoxia long-term effects on cancer progression and some underlying mechanisms using both in vitro and in vivo models of triple negative breast cancer (TNBC).

Association of intracellular lipid accumulation in subcutaneous adipocyte precursors and plasma adipokines in bariatric surgery candidates.

Background: The adipocyte expansion is a critical process with implications in the pathogenesis of obesity associated metabolic syndrome. Impaired adipogenesis leads to dysfunctional, hypertrophic adipocytes, local inflammation and peripheric insulin resistance.

Methods: We assessed the relationship between the adipogenic differentiation capacity of the subcutaneous adipose derived stem cells (ASCs), evaluated by total lipid accumulation, and the metabolic and hormonal profile in a group of obese female patients proposed for bariatric surgery (N = 20) versus normal weight female controls (N = 7).

The Unexplored Role of Intra-articular Adipose Tissue in the Homeostasis and Pathology of Articular Joints.

Intra-articular adipose tissue deposits known as articular fat pads (AFPs) are described to exist within synovial joints. Their assumed role in normal joint biomechanics is increasingly objectivized by means of advanced methods of functional imaging. AFPs possess structural similarity with body subcutaneous white adipose tissue (WAT), however, seems to be regulated by independent metabolic loops.

Clinical and histological predictive risk factors of atrial fibrillation in patients undergoing open-heart surgery.

Postoperative atrial fibrillation (POAF) is a common complication subsequent to cardiac surgery. Various risk factors have been reported for the development of this complication; however, their precise role in POAF is unknown. In the present study, we attempted to identify clinical factors and histopathological changes in atrial tissue that may predict the development of POAF.

Stem cells for the treatment of musculoskeletal pain.

Musculoskeletal-related pain is one of the most disabling health conditions affecting more than one third of the adult population worldwide. Pain from various mechanisms and origins is currently underdiagnosed and undertreated. The complexity of molecular mechanisms correlating pain and the progression of musculoskeletal diseases is not yet fully understood.

Potential value of in situ cellular immune response in HPV subtype 16 and 18 positive cervical cancer.

Unlabelled: There is no doubt that the association between infection of the cervical epithelium by carcinogenic Human Papilloma Virus (HPV), particularly types 16 and 18, and cervical cancer (CC) is responsible for the activation of the immune response (IR). Research on tumor infiltrating lymphocytes at the primary tumor site could give us important information on how the immune cells are fighting against cancer.

Aim: The aims of our study were to assess HPV status and to evaluate the significance of in situ cellular IR in CC.

Novel approaches for treating musculoskeletal diseases: molecular orthopedics and systems medicine.

Molecular medicine uses knowledge about cell structure and function for disease, diagnostics, stage characterisation and treatment. The advent of genomic technologies is considerably leading to developments in the field of molecular medicine. The accumulation of detailed information about gene expression, epigenetic variability, protein transcription and functional modulation is contributing to a new era in medicine.

Stem cells derived from osteoarthritic knee mesenchymal tissues: a pilot study.

Regenerative medicine is a promising approach for addressing musculoskeletal disorders. Successful implementation of regenerative therapies is based upon existence of reliable, easy accessible cell sources. Mesenchymal tissues removed during total knee replacement (TKR) were investigated as a potential autologous stem cell source.

Isolation and phenotypic characterisation of stem cells from late stage osteoarthritic mesenchymal tissues.

Introduction: Osteoarthritis (OA) represents an increasing health issue worldwide. Regenerative medicine (RM) has raised the hope for introducing revolutionary therapies in clinical practice. Detection of autologus cell sources can improve accessibility to RM strategies.

Intrinsic growth deficiencies of mesenchymal stromal cells in myelodysplastic syndromes.

Myelodysplastic syndromes (MDSs) are clonal disorders of hematopoietic stem cells (HSCs) characterized by ineffective hematopoiesis. MDSs are responsible for 1 or several peripheral cytopenias. The evidence accumulated in recent years demonstrates that in addition to HSC defects, a particular role is also played by stromal microenvironment dysfunctions, which mediate the direct contact with hematopoietic precursor cells (HPCs).

Focal adhesion protein abnormalities in myelodysplastic mesenchymal stromal cells.

Direct cell-cell contact between haematopoietic progenitor cells (HPCs) and their cellular microenvironment is essential to maintain 'stemness'. In cancer biology, focal adhesion (FA) proteins are involved in survival signal transduction in a wide variety of human tumours. To define the role of FA proteins in the haematopoietic microenvironment of myelodysplastic syndromes (MDS), CD73-positive mesenchymal stromal cells (MSCs) were immunostained for paxillin, pFAK [Y(397)], and HSP90α/β and p130CAS, and analysed for reactivity, intensity and cellular localisation.
