Identification of Patients with Pancreatic Cancer by Electron Paramagnetic Resonance Spectroscopy of Fatty Acid Binding to Human Serum Albumin.

An effective biological marker for pancreatic adenocarcinoma (PAC) is not available so far. Here, we investigate how electron paramagnetic resonance (EPR) spectroscopy of spin-labeled fatty acid (FA) molecules binding to human serum albumin (HSA) in human serum is a suitable method for the identification of patients with PAC through detection of PAC-induced changes of FA binding to albumin. The functionality of HSA to bind FA is investigated in serum samples of 35 patients with PAC, 26 patients with benign pancreatic tumors (BPD), and 24 healthy individuals by continuous wave (CW) EPR spectroscopy by simply dissolving 16-DOXYL stearic acid as spin-labeled FA.

Postoperative results, pathologic outcome, and long-term patency rate of autologous vein reconstruction of the mesentericoportal axis after pancreatectomy.

Purpose: In advanced pancreatic cancer (PC), en-bloc vein resection and reconstruction (VR) is a curative option in oncologic pancreatectomy. However, few data about long-term patency rates after autologous venous reconstruction are available. We aimed to analyze whether early postoperative morbidity is increased by additional VR.

Fatty Acid Binding to Human Serum Albumin in Blood Serum Characterized by EPR Spectroscopy.

One of the functions of Human Serum Albumin (HSA) is binding and transport of fatty acids. This ability could be altered by the presence of several blood components such as toxins or peptides - which in turn alters the functionality of the protein. We aim at characterizing HSA and its fatty acid binding in native serum environment.

[Sacral nerve modulation in coloproctology].

Sacral nerve modulation and stimulation (SNM/SNS) is a minimally invasive treatment for fecal incontinence, which has become widely established in recent years. Modulation of sacral nerve roots occurs through an electrode which is placed in the sacral foramina S2-4. By complex spinal and supraspinal mechanisms, rectal compliance is improved and anal incontinence episodes are reduced.

The single-incision laparoscopic surgery technique has questionable advantages in colorectal surgery.

Background: Laparoscopic procedures have increasingly been accepted as standard in surgical treatment of benign and malignant entities, resulting in a continuous evolution of operative techniques. Since one of the aims in laparoscopic colorectal surgery is to reduce access trauma, one possible way is to further reduce the surgical site by the single-incision laparoscopic surgery technique (SLS). One of the main criticisms concerning the use of SLS is its questionable benefit combined with its technical demands for the surgeon.
