With new techniques 1 9 bone marrow transplant (BMT) recipients were monitored for lymphocyte proliferation and specific lgG production in vitro by cytomegalovirus (CMV) antigen in solid phase. Twelve patients got a reactivated CMV infection as defined by virus isolation or serum lgG conversion. Lymphocyte proliferation and in vitro lgG production responses were significantly stronger in these ...

The presence of multiple homologues of the same yeast Atg protein endows an additional layer of complexity on the autophagy pathway in higher eukaryotes. The physiological function of the individual genes, however, remains largely unknown. Here we investigated the role of the two Caenorhabditis elegans homologues of the cysteine protease Atg4 in the pathway responsible for degradation of protei...

OBJECTIVE The incidence of nosocomial infections, predominantly gastrointestinal and respiratory, in children in developed countries is high, ranging from 5% to 44%. There is no effective strategy for preventing these infections. The objective of our study was to investigate the role of Lactobacillus GG (LGG) in preventing nosocomial gastrointestinal and respiratory tract infections at a pediat...

BACKGROUND AND OBJECTIVES A 2007 meta-analysis showed probiotics, specifically Lactobacillus rhamnosus GG (LGG), shorten diarrhea from acute gastroenteritis (AGE) by 24 hours and decrease risk of progression beyond 7 days. In 2005, our institution published a guideline recommending consideration of probiotics for patients with AGE, but only 1% of inpatients with AGE were prescribed LGG. The obj...

Brain tumors are the most common solid tumor diagnosed in childhood that account for significant morbidity and mortality. New therapies are urgently needed; hence, we conducted the first ever prospective open-label phase II trials of the biological response modifier, poly-ICLC, in children with brain tumors. Poly-ICLC is a synthetic double-stranded RNA that has direct antiviral, antineoplastic,...

Live probiotics are effective in reducing gut permeability and inflammation. We have previously reported that Lactobacillus reuteri ZJ617 (ZJ617) with high adhesive and Lactobacillus rhamnosus GG (LGG) can ameliorate intestine inflammation induced by lipopolysaccharide (LPS). The present study was aimed at elucidating the roles of ZJ617 and LGG in alleviating the LPS-induced barrier dysfunction...

OBJECTIVE Experimental evidence revealed that obesity-associated non-alcoholic fatty liver disease (NAFLD) is linked to changes in intestinal permeability and translocation of bacterial products to the liver. Hitherto, no reliable therapy is available except for weight reduction. Within this study, we examined the possible effect of the probiotic bacterial strain Lactobacillus rhamnosus GG (LGG...

BACKGROUND & AIMS The aim of our study was to investigate the role of Lactobacillus GG (LGG) in the prevention of gastrointestinal and respiratory tract infections in children who attend day care centers. METHODS We conducted a randomized, double-blind, placebo-controlled trial in 281 children who attend day care centers. They were randomly allocated to receive LGG at a dose of 10(9) colony-f...

Extensive genomic and gene expression studies have been performed in gliomas, but the epigenetic alterations that characterize different subtypes of gliomas remain largely unknown. Here, we analyzed the methylation patterns of 807 genes (1536 CpGs) in a series of 33 low-grade gliomas (LGGs), 36 glioblastomas (GBMs), 8 paired initial and recurrent gliomas, and 9 controls. This analysis was perfo...

BACKGROUND Chemotherapy is widely accepted as first-line therapy for pediatric low-grade gliomas (LGG). Treatment modalities for further progression are not clearly established. The aim of the study was to determine the feasibility and long-term outcome of repeated chemotherapy for children with recurrent LGG. METHODS The study group consisted of patients who received a second line of chemoth...
