Article Synopsis
  • The study examines the role of the pseudokinase Tribbles 3 (TRIB3) in energy metabolism by using Trib3 knockout mice to understand its effects on fat cells and overall metabolic health.
  • Results show that while Trib3 mice are fatter, their insulin sensitivity doesn't change, and their fat cells are smaller with increased proliferation markers, suggesting TRIB3 affects how these cells grow and store fat.
  • Overall, TRIB3 is implicated in various cellular processes through different signaling pathways, indicating it plays a crucial role in maintaining the health of fat tissue rather than just one specific function.

Article Synopsis
  • Micro-environmental factors like stromal and immune cells, along with hormones, significantly influence the progression of melanoma.
  • A study with 89 melanoma patients revealed a notable link between elevated gastrin levels and increased melanoma thickness and metastasis, suggesting higher cancer progression risks.
  • Gastrin was shown to promote melanoma cell migration and invasion through CCK2 receptors, with interactions in the tumor environment potentially exacerbating these effects, especially when combined with dermal fibroblasts/myofibroblasts.

The psoriatic skin resembles wound healing, and it shows abnormalities at the basement membrane (BM), also in the non-lesional skin. Fibroblast-derived dermal periostin has well-known functions in wound healing and Th2-mediated diseases, such as atopic dermatitis. Here we show that serum periostin level was elevated in psoriatic patients, remarkably in the systemically treated ones.

The proper functioning of mesenchymal stem cells (MSCs) is of paramount importance for the homeostasis of the body. Inflammation and infection can alter the function of MSCs, which can also affect the regenerative potential and immunological status of tissues. It is not known whether human herpes simplex viruses 1 and 2 (HSV1 and HSV2), well-known human pathogens that can cause lifelong infections, can induce changes in MSCs.

: During the reconstruction of alar defects involving the upper lip, reconstructive surgeons face the need for various thicknesses of tissues crucial to preserving the facial sulcus which is important for a cosmetically acceptable result. Our aim was to reconstruct the deep perialar and thinner lateral nasal alar defect in a single step procedure with a suitable flap which is reliable, has appropriate blood supply and provides an esthetically good result. : Extended alar defect was reconstructed with a combined flap in 10 cases.

Climate change is altering the phenology of trophically linked organisms, leading to increased asynchrony between species with unknown consequences for ecosystem services. Although phenological mismatches are reported from several ecosystems, experimental evidence for altering multiple ecosystem services is hardly available. We examined how the phenological shift of apple trees affected the abundance and diversity of pollinators, generalist and specialist herbivores and predatory arthropods.

Matrix metalloproteinase (MMP)-7, unlike many MMPs, is typically expressed in epithelial cells. It has been linked to epithelial responses to infection, injury, and tissue remodeling including the progression of a number of cancers. We have now examined how MMP-7 expression changes in the progression to esophageal adenocarcinoma (EAC), and have studied mechanisms regulating its expression and its functional significance.

: Immediate breast reconstruction is often applied after mastectomy. However, inappropriate surgical technique, postoperative radiotherapy and infection may lead to tissue necrosis and implant protrusion. Traditional therapies frequently fail.

The well-known action of the gastric hormone gastrin in stimulating gastric acid secretion is mediated by activation of cholecystokinin-2 receptors (CCK2R). The latter are expressed by a variety of cell types suggesting that gastrin is implicated in multiple functions. During wound healing in the stomach CCK2R may be expressed by myofibroblasts.

Glucagon-like peptide (GLP)-2 stimulates intestinal epithelial proliferation by acting, in part, via IGF release from sub-epithelial myofibroblasts. The response of myofibroblasts to GLP-2 remains incompletely understood. We studied the action of GLP-2 on myofibroblasts from colon cancer and adjacent tissue, and the effects of conditioned medium from these cells on epithelial cell proliferation, migration and invasion.

Introduction: Barrett's esophagus (BE) is the only known precursor of adenocarcinoma occuring in the lower third of the esophagus. According to statistics, severity and elapsed time of gastroesophageal reflux disease (GERD) are major pathogenetic factors in the development of Barrett's esophagus.

Patients And Methods: In a retrospective study between 2001 and 2008, we compared the preoperative results (signs and sympthoms, 24 hour pH manometry, esophageal manometry, Bilitec) and treatment efficacy of 176 GERD patients and 78 BE patients, who have undergone laparoscopic Nissen procedure for reflux disease.

Background: The Alvarado score is a clinical scoring system used in the diagnosis of acute appendicitis. This study aimed to compare the reliability of the Alvarado score and clinical judgment and to refine the score to make it easier to use.

Methods: In this prospective, randomized study, patients presenting at the authors' outpatient department with suspected appendicitis during a 1-year period were assigned in weekly alternation to either group A or group B.

In this paper is given a short introduction to the functioning of the group therapy of psychotic patients at our unit; outlining also other aspects of their treatment (medication, hospitalisation, group therapy). By collecting examples from the reports of the group therapy we illustrate how the medicaments appear in the conversations. We analyse the given data from three different point of view: interactional, thematic and by the psychotic contents.
