Background: The complete resection of liver metastases from colorectal cancer is the major determinant of longterm survival. The effectiveness of current chemotherapy regimens has made treatment algorithms more flexible and resulted in many different options. Recently, the pathological response to chemotherapy has emerged as another important prognostic marker.

Pulmonary bullae tend to progressively increase in their size, and spontaneous regressions have very rarely been reported. In this paper, we report the case of an older woman experiencing the spontaneous resolution of a giant pulmonary bulla.

Methods And Study Design: Alternating cycles of vincristine (1.5 mg/m2), doxorubicin (80 mg/m2) and cyclophosfamide (1200 mg/m2) (weeks 0, 6, 13, 22 and 31), ifosfamide (9 g/m2), vincristine (1.
This report presents a case of a 16-year-old hypertensive boy who presented to our clinic. Laboratory findings showed severe hypokalemia and markedly increased plasma renin activity. Abdominal ultrasonography and contrast-enhanced computed tomography of the abdomen revealed a well-circumscribed, solid, hypoenhancing cortical lesion (2 cm) in the lower pole of the left kidney.

Although TNFalpha secretion by adipose cells is probably induced, most notably by TLR ligands, the activation and secretion pathways of this cytokine are not yet entirely understood. Moreover, given that macrophagic infiltration is a characteristic of obesity, it is difficult to clearly establish the level of involvement of the different cellular types present within the adipose tissue during inflammation.

Objectives: Recent reports demonstrated in vitro the efficacy of fluvastatin in inhibiting hepatitis C virus (HCV) replication and a synergistic effect in association with interferon-alpha (IFN-alpha). In vivo the inhibition of HCV replication by statins has not been demonstrated. We evaluated in this open-label, randomized controlled study the efficacy of fluvastatin as adjuvant to pegylated-(PEG)-IFN and ribavirin in HIV/HCV genotype 1 co-infected patients.

Anhydrobiosis is a highly stable state of suspended animation in an organism due to its desiccation, which is followed by recovery after rehydration. Changes occurring during drying could damage molecules, including DNA. Using the anhydrobiotic tardigrade Paramacrobiotus richtersi as a model organism, we have evaluated the effects of environmental factors, such as temperature and air humidity level (RH), on the survival of desiccated animals and on the degradation of their DNA.
View Article and Find Full Text PDFIntroduction: The use of a simple, safe, and easy to perform assessment tool, like gait speed, to evaluate vulnerability to adverse outcomes in community-dwelling older people is appealing, but its predictive capacity is still questioned. The present manuscript summarises the conclusions of an expert panel in the domain of physical performance measures and frailty in older people, who reviewed and discussed the existing literature in a 2-day meeting held in Toulouse, France on March 12-13, 2009. The aim of the IANA Task Force was to state if, in the light of actual scientific evidence, gait speed assessed at usual pace had the capacity to identify community-dwelling older people at risk of adverse outcomes, and if gait speed could be used as a single-item tool instead of more comprehensive but more time-consuming assessment instruments.

Background: Telbivudine is a potent inhibitor of hepatitis B virus (HBV) replication without anti-HIV type-1 (HIV-1) activity demonstrated in vitro; however, very few clinical data on HIV-1-infected patients are available at present. Because it represents a therapeutic option in HIV-1-HBV-coinfected patients who do not require antiretroviral therapy, we strictly monitored three HIV-1-HBV-coinfected patients treated with telbivudine monotherapy for chronic hepatitis B.
Methods: We performed molecular analysis of HBV DNA and of HIV-1 reverse transcriptase and protease RNA and DNA sequences in three HIV-1-HBV-coinfected patients treated with telbivudine monotherapy.
Objectives: High serum total cholesterol and low-density lipoprotein (LDL) levels have been demonstrated to increase the probability of a sustained viral response (SVR) in chronic hepatitis C. Conversely, insulin resistance reduces SVR rates. We investigated the influence of baseline glucose and lipid values on the outcome of hepatitis C virus (HCV) treatment in HIV-1 infected subjects.

Four experiments were conducted in which the eutardigrade Macrobiotus richtersi was used as a model species. Desiccated (in leaf litter or on paper) and hydrated tardigrades (fed or starved) were flown on FOTON-M3 for 12 days in September 2007, which, for the first time, allowed for a comparison of the effects of the space environment on desiccated and on active animals.

Sarcopenia is characterized by a lower skeletal muscle quantity, higher fat accumulation in the muscle, lower muscle strength, and lower physical performance. The most commonly used, low cost and accessible methods to assess skeletal muscle mass include dual energy X-ray absorptiometry (DEXA), anthropometry and bioelectrical impedance analysis (BIA). Magnetic resonance imaging (MRI), computerized tomography (CT) and creatinine excretion are the most specific golden standards for assessing muscle mass or cross sectional muscle area.

Methods: The possibility of a correlation between T-cell homeostatic parameters and IL-7/IL-7R was investigated in 22 LTNPs (CD4 count > or =500 cells/microL for >10 years) vs. HIV-positive patients at different disease stages [12 early: CD4 count > or =400 cells/microL ; 15 late (AIDS-presenters): CD4 count < or =150 cells/microL ].
The influence of age and sex on chemotherapy-related toxicity was evaluated in children and adults with non metastatic osteosarcoma. treatment consisted of methotrexate (MTX, 12 g/m(2)), cisplatin (CDP 120 mg/m(2)) and doxorubicin (ADM 75-90 mg/m(2)) and high-dose ifosfamide (HDIFO). toxicity data from 1,051 courses (295 with MTX, 756 based on doxorubicin, cisplatin and high-dose ifosfamide) were analyzed.

Macrobiotus macrocalix Bertolani & Rebecchi, 1993 was chosen as the test species since it belongs to a group of species in which the taxonomy is quite problematic. Animals and eggs belonging to three Italian and one Swedish populations have been investigated.
View Article and Find Full Text PDFFluvastatin showed anti-hepatitis C virus (HCV) activity in vitro, through the inhibition of geranylgeranylation of cellular proteins, and a synergistic effect with interferon (IFN)-alpha. Nevertheless statins up-regulate low-density lipoprotein (LDL) receptor, required for HCV cell entry, and the closely related scavenger receptors SRBI and CD36; moreover they reduce class II major histocompatibility complex expression on antigen presenting cell, modulating T-cell activation. In vivo LDL levels have been identified as prognostic indicator of sustained viral response to IFN in patients with HCV infection, suggesting that lipid-lowering agents might conversely favour HCV entry into the hepatocytes and translate into higher viral replication.

Background: A 73-year-old white man was referred to a cancer genetics clinic for evaluation of a approximately 20-year history of mixed upper and lower gastrointestinal polyposis, including hyperplastic, inflammatory and adenomatous polyps, colonic ganglioneuromas, and associated diffuse, esophageal glycogenic acanthosis. Two synchronous gastric carcinomas had been identified before referral and the patient had undergone a total gastrectomy, omentectomy and cholecystectomy. Multiple hyperplastic polyps and small, sessile polyps were also observed in the gastrectomy specimen.
