A half century (1961-2011) of applying microsurgery to experimental liver research

World Journal of Hepatology 2012年第7期4卷 199-208页

The development of microsurgery has been dependent on experimental animals. Microsurgery could be a very valuable technique to improve experimental models of liver diseases. Microdissection and microsutures are the two main microsurgical techniques that can be considered for classifying the experimental models developed for liver research in the rat. Partial portal vein ligation, extrahepatic cholestasis and hepatectomies are all models based on microdissection. On the other hand, in portacaval shunts, orthotopic liver transplantation and partial heterotopic liver transplantation, the microsuture techniques stand out. By reducing surgical complications, these microsurgical techniques allow for improving the resulting experimental models. If good experimental models for liver research are successfully developed, the results obtained from their study might be particularly useful in patients with liver disease. Therefore experimental liver microsurgery could be an invaluable way to translate laboratory data on liver research into new clinical diagnostic and therapeutic strategies.

Management of pancreatic cancer in the elderly

引用

World Journal of Gastroenterology 2016年第2期22卷 764-775页

作者： Oliver Higuera Ismael Ghanem Rula Nasimi isabel prieto Laura Koren Jaime Feliu Department of Medical Oncology La Paz University Hospital28046 MadridSpain Department of General Surgery La Paz University Hospital28046 MadridSpain Department of Radiology 12 de Octubre University Hospital28041 MadridSpain

Currently, pancreatic adenocarcinoma mainly occurs after 60 years of age, and its prognosis remains poor despite modest improvements in recent decades. The aging of the population will result in a rise in the incidence of pancreatic adenocarcinoma within the next years. Thus, the management of pancreatic cancer in the elderly population is gaining increasing relevance. Older cancer patients represent a heterogeneous group with different biological, functional and psychosocial characteristics that can modify the usual management of this disease, including pharmacokinetic and pharmacodynamic changes, polypharmacy, performance status, comorbidities and organ dysfunction. However, the biological age, not the chronological age, of the patient should be the limiting factor in determining the most appropriate treatment for these patients. Unfortunately, despite the increased incidence of this pathology in older patients, there is an underrepresentation of these patients in clinical trials, and the management of older patients is thus determined by extrapolation from the results of studies performed in younger patients. In this review, the special characteristics of the elderly, the multidisciplinary management of localized and advanced ductal adenocarcinoma of the pancreas and the most recent advances in the management of this condition will be discussed, focusing on surgery, chemotherapy, radiation and palliative care.

Gut Lymphangiopathy: Adding Fuel to the Fire in Chronic Liver Disease

Advances in Bioscience and Biotechnology 2019年第10期10卷 305-319页

The splanchnic inflammation inchronic liver disease increases intestinal angiogenesis. In the current study our aim was demonstrating that the small bowel lymphangiogenesis is associated with angiogenesis in chronic cholestasis in the rat. A stereological study of the lymphatic microcirculation in the small intestine was performed in cholestatic rats. Portal enteropathy in cholestasis increases lymphatic microvessels in the mucosa and submucosa layers. Thus, the lymphatic microvessel volume fraction was superior (p < 0.001) in the mucosa (0.16 ± 0.01) and submucosa (0.16 ± 0.01), in regard to the muscle layer 0.015 ± 0.01. The lymphatic microvessel length density was higher in the mucosa (76.89 ± 2.86 mm-2;p -2;p < 0.01), in relationship to the muscle layer (5.04 ± 2.92 mm-2). These alterations predominate in the duodenum (volume fraction: 0.10 ± 0.01 and length density: 33.55 ± 5.98 mm-2) and ileum (volume fraction: 0.16 ± 0.01 and length density: 38.62 ± 6.07 mm-2). This study demonstrates the predominance of an increased lymphangiogenic response in both end sides of the small bowel associated with chronic liver disease. Since the porto-systemic venous collateral circulation in the chronic liver insufficiency is developed in the ends of the gastrointestinal tract, the excessive duodeno-ileal lymphangiogenesis could suggest the development of amesenteric-systemic lymphatic bypass in the chronic portal hypertension.

Portal hypertension-related inflammatory phenotypes: From a vitelline and amniotic point of view

Prehepatic portal hypertension induces a splanchnic low-grade inflammatory response that could switch to high-grade inflammation with the development of severe and life-threatening complications when associated with chronic liver disease. The extraembryonic origin of the portal system maybe determines the regression to an extraembryonic phenotype, i.e., vitellogenic and amniotic, during the evolution of both types of portal hypertension. Thus, prehepatic portal hypertension, or compensated hypertension by portal vein ligation in the rat, is associated with molecular mechanisms related to vitellogenesis, where hepatic steatosis and splanchnic angiogenesis stand out. In turn, extrahepatic cholestasis in the rat induces intrahepatic portal hypertension, or decompensated hypertension, with ascites and hepatorenal syndrome. The splanchnic interstitium, the mesenteric lymphatic system, and the peritoneal mesothelium seem to create an inflammatory pathway that could have a key pathophysiological relevance in the production of ascites. The hypothetical comparison between the ascitic and the amniotic fluid also allows for translational investigation. The induced regression of the splanchnic system to extraembryonic functions by portal hypertension highlights the great relevance of the extraem-bryonic structures even during postnatal life.

Inflammatory pseudotumour of the spleen associated with splenic tuberculosis

World Journal of Gastrointestinal Surgery 2014年第12期6卷 248-252页

Inflammatory pseudotumor(IPT) of the spleen is an uncommon entity with an uncertain aetiology. Inflammatory pseudotumors present diagnostic difficulties because the clinical and radiological findings tend to suggest a malignancy. The symptoms include weight loss, fever, and abdominal pain. Most cases of splenic IPT present solitary relatively large well circumscribed masses on imaging. The diagnosis in the majority of the cases is made after histopathologic study of splenectomy specimens. The IPTs that occur in the spleen and liver are typically associated with Epstein-Barr virus. Thirtyseven percent of all new cases of active tuberculosis infection are extrapulmonary tuberculosis and tuberculous lymphadenitis the most commonly occurring form of extrapulmonary tuberculosis. We report the case of an inflammatory pseudotumor of the spleen associated with splenic tuberculous lymphadenitis in a 50-year-old female patient who was preoperatively diagnosed with a malignant spleen tumour based on her history of breast of carcinoma.

Genotoxicity evaluation of two derived products from Allium extracts: s-propylmercaptocysteine and s-propyl mercaptoglutathione

FOOD BIOSCIENCE 2023年第3期53卷 1603-1611页

Propyl-propane-thiosulfonate (PTSO) is one of the main organosulfur compounds present in Allium essential oils with a widely documented biological activity. For this reason, it could be used as a food and feed additive in the agri-food industry. A genotoxicity evaluation of substances and their metabolites present in food is necessary to guarantee the consumer's health following the recommendations of the European Food Safety Authority (EFSA). To evaluate the toxicological profile of derivatives of PTSO, the cytotoxicity, an Ames test, a micronucleus test and the comet assay were performed. Results showed that non-cytotoxic effects were observed in Caco-2 exposed to s-propyl mercaptocysteine (CSSP) and s-propyl mercaptoglutathione (GSSP) (0-450 mu M). The mutagenicity index remained in the range of 0.6-1.4 for both compounds, showing no mutagenic effects for the concentrations of 5000-312.5 mu g GSSP/plate and 250-15.63 mu g CSSP/plate. Moreover, the % binucleated cells with micronuclei were 1.3-2.2 and 1.6-2.7 for GSSP and GSSP, respectively. For comet assays there was no DNA-genotoxic or oxidative damage in a concentration range of 112.5-450 mu M. Therefore, we can conclude that these compounds are not genotoxic at the conditions tested. These results support that the presence of CSSP and GSSP in the food/ feed is not of concern, although further studies are needed to complete their safety profile.
