Platelet-derived growth factor (PDGF) cross-signaling via non-corresponding receptors indicates bypassed signaling in colorectal cancer.

Platelet-derived growth factor (PDGF) signaling, besides other growth factor-mediated signaling pathways like vascular endothelial growth factor (VEGF) and epidermal growth factor (EGF), seems to play a crucial role in tumor development and progression. We have recently provided evidence for upregulation of PDGF expression in UICC stage I-IV primary colorectal cancer (CRC) and demonstrated PDGF-mediated induction of PI3K/Akt/mTOR signaling in CRC cell lines. The present study sought to follow up on our previous findings and explore the alternative receptor cross-binding potential of PDGF in CRC.

KMP01D Demonstrates Beneficial Anti-inflammatory Effects on Immune Cells: An Preclinical Study of Patients With Colorectal Cancer.

Colorectal cancer (CRC) is frequently associated with dysbiosis of the gut microbiome which, together with a compromised gut barrier, can result in perioperative endotoxin leakage into the circulation. Constant local and systemic inflammatory activity is suggested to facilitate metastases formation. Previous studies have pointed to the capacity of a colostrum preparation to neutralize endotoxins within the gastrointestinal tract which could ameliorate associated inflammatory responses and tumor recurrence in affected patients.

Risk of tumor progression in colon carcinoma resection and perioperative prophylaxis with polyvalent immunoglobulins - per aspera ad astra.

There is strong evidence that tumor progression in the postoperative period is attributable to the influx of lipopolysaccharides (LPS) into the blood from the gastrointestinal (GI) lumen. Although several research groups have emphasized the need to neutralize LPS antigens from the GI tract to prevent tumor progression and reduce the inflammatory response, a therapeutic option to achieve this has not been put forward hitherto. Enterally applied immunoglobulins (IgG) in the form of colostrum concentrates are able to neutralize LPS antigens from the GI tract and to reduce the inflammatory response during abdominal surgery.

Polyvalent immunoglobulins with vitamin D3 and vitamin B12 in the treatment of Sjogren's syndrome in a vegetarian with stomatitis, glossodynia, xerostomia, and elevated antinuclear antibodies: Case report .

Background: Sjogren's syndrome, involving sicca symptoms with xerostomia, stomatitis, and considerable pain is a difficult-to-treat autoimmune disease where the treatment options are limited and, as in the case of methotrexate, have a low therapeutic index.

Case Report: This case report concerns a male patient, aged 75 years and vegetarian, with Sjogren's syndrome subsequently confirmed by salivary gland biopsy. Serum antinuclear antibodies (ANA) were elevated (1 : 320).

Exclusive inhibition of PI3K/Akt/mTOR signaling is not sufficient to prevent PDGF-mediated effects on glycolysis and proliferation in colorectal cancer.

Platelet-derived growth factor (PDGF) and signaling via its receptors plays a crucial role in tumor cell proliferation and thus may represent an attractive target besides VEGF/EGFR-based antibody therapies. In this study we analyzed the influence of PDGF in colorectal cancer. PDGF was expressed intensively in early and even more intensively in late stage primary CRCs.

Antibody reactivity of a standardized human serum protein solution against a spectrum of microbial pathogens and toxins: comparison with fresh frozen plasma.

In this study, we compared a standardized solution of human serum protein (HSP) and fresh frozen plasma (FFP) with regard to the antibody specificity against a number of microbial pathogens and some important pathogenicity factors of bacterial pathogens. Due to the clinical use of HSP and FFP for therapeutical plasma exchange, we have chosen a spectrum of microbial pathogens for serological analysis that is critical in clinical settings. With the enzyme-linked immunosorbent assay technique, we could show that HSP contains marked IgG antibody reactivity against antigens of Escherichia coli, Campylobacter jejuni, Enterobacter sakazakii, Proteus mirabilis, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, S.

Shiga Toxin-Producing Escherichia coli Infections in Germany .

A prospective study was carried out in collaboration with two children's hospitals in Würzburg, Germany to assess the incidence and clinical manifestations of infections due to Shiga toxin-producing Escherichia coli (STEC) in children. Between 1991 and 1995, stool samples from 2788 children with enteritis were investigated for the occurrence of STEC. STEC cultures from stools were screened using PCR with primers complementary to Shiga toxin 1(Stx1) and Shiga toxin 2 (Stx2) genes.
