BACKGROUND: Diffuse intrinsic pontine glioma (DIPG), or high-grade brainstem glioma (BSG), is one of the major causes of brain tumor-related deaths in children. Its prognosis has remained poor despite numerous efforts to improve survival. Panobinostat, a histone deacetylase inhibitor, is a targeted agent that has recently shown pre-clinical efficacy and entered a phase I clinical trial for the treatment of children with recurrent or progressive DIPG. METHODS: A collaborative pre-clinical study was conducted using both a genetic BSG mouse model driven by PDGF-B signaling, p53 loss, and ectopic H3...

Lenalidomide is an immunomodulatory compound with high clinical activity in multiple myeloma. Lenalidomide binding to the Cereblon (CRBN) E3 ubiquitin ligase results in targeted ubiquitination and degradation of the lymphoid transcription factors Ikaros (IKZF1) and Aiolos (IKZF3) leading to growth-inhibition of multiple myeloma cells. Recently, Basigin (BSG) was identified as another protein regulated by CRBN that is involved in the activity of lenalidomide. Here, we analyzed the prognostic value of IKZF1, IKZF3, CRBN and BSG mRNA expression levels in pretreatment plasma cells from sixty patients with newly diagnosed multiple myeloma uniformly treated with lenalidomide in combination with intensive chemotherapy within a clinical trial...

Plant derived polymers like mucilage have evoked great attention in the field of functional food ingredient delivery. The objective of this study was to evaluate the potential of basil seed gum nanoparticles (BSG NPs) as an oral delivery system for glutathione (GSH). BSG NPs (1-0.25mgml(-1)) were fabricated by ion gelling technique and calcium was used as a cross-linking agent (0.7-0.3mgml(-1)). The results showed that BSG NPs (298-595nm) have spherical shape and the relative viscosity revealed that the possibility of agglomeration of BSG NPs is low...

Soft tissue sarcomas (STS) are rare tumours arising in mesenchymal tissues, and can occur almost anywhere in the body. Their rarity, and the heterogeneity of subtype and location means that developing evidence-based guidelines is complicated by the limitations of the data available. However, this makes it more important that STS are managed by teams, expert in such cases, to ensure consistent and optimal treatment, as well as recruitment to clinical trials, and the ongoing accumulation of further data and knowledge...

The diffusion of selenite (labeled with (75)Se) in compacted Beishan granite (BsG) was investigated using the in-diffusion capillary method at pH values from ∼2.0 to ∼11.0 under oxic and anoxic conditions. The results indicate that the apparent diffusion coefficient (Da) values of selenite in BsG always reached the minimum at approximately pH 5. Unexpectedly, the Da values under oxic conditions are nearly one order of magnitude lower than those under the anoxic conditions. Further characterization reveals the existence of redox-sensitive Fe(II)-containing components, which can be responsible for the great difference in Da values...

Brewer's spent grain (BSG) and wheat bran (WB) are industrial byproducts that accumulate in millions of tons per year and are typically applied as animal feed. Since both byproducts show a great potential as substrates for fermentation, the approach developed in this study consists of utilizing these lignocellulosic byproducts for biomass production of the medicinal fungus Hericium erinaceus through submerged cultivation. To increase the biological efficiency of the bioconversion, acidic pretreatment was applied yielding a bioconversion of 38...

Biolog Phenotype Microarray (PM) is a technology allowing simultaneous screening of the metabolic behaviour of bacteria under a large number of different conditions. Bacteria may often undergo several cycles of metabolic activity during a Biolog experiment. We introduce a novel algorithm to identify these metabolic cycles in PM experimental data, thus increasing the potential of PM technology in microbiology. Our method is based on a statistical decomposition of the time-series measurements into a set of growth models...

Hydrocolloid interactions with solvent/cosolutes play a vital role in the resolution of their functional properties. Basil seed gum (BSG) is a plant-derived hydrocolloid which has been found many applications in food formulations as stabilizer, emulsifier, thickener and gelling agents. Sucrose and lactose are the most effective sugars in textural and sensorial properties of bakery and dairy products which adding them to solutions containing hydrocolloids can be helpful to approach a proper formula. In this paper, the effect of temperature (25-65°C), sucrose (10, 20, 30 and 40%) and lactose (5, 10 and 15%) were investigated through some molecular parameters of BSG...

AIM: The management of large non-pedunculated colorectal polyps (LNPCP) is complex, with widespread variation in management and outcome, even amongst experienced clinicians. Variation in the assessment and decision-making processes are likely to be a major factor in this variability. The creation of a standardised minimum dataset to aid decision making may therefore result in improved clinical management. METHOD: An official working group of thirteen multidisciplinary specialists was appointed by the Association of Coloproctology of Great Britain and Ireland (ACPGBI) and the British Society of Gastroenterology (BSG) to develop a minimum dataset on LNPCP...

Members of the Bacillus subtilis group (BSG) possess industrial applicability; unfortunately, B. subtilis and its phylogenetically closest species are indistinguishable from one another using 16S rDNA sequencing, physiological and biochemical tests. Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) is a relatively novel technique for the fast and reliable identification of microorganisms. The aim of this study was to construct a unique analytical in-house database (IHDB) for BSG discrimination based on whole-cell protein fingerprinting using MALDI-TOF MS, as well as to discover biomarkers from the MS peaks to generate a classification model for further differentiation using the ClinProTools software...

Xk-related protein (Xkr) 8, a protein carrying 10 transmembrane regions, is essential for scrambling phospholipids during apoptosis. Here, we found Xkr8 as a complex with basigin (BSG) or neuroplastin (NPTN), type I membrane proteins in the Ig superfamily. In BSG(-/-)NPTN(-/-) cells, Xkr8 localized intracellularly, and the apoptosis stimuli failed to expose phosphatidylserine, indicating that BSG and NPTN chaperone Xkr8 to the plasma membrane to execute its scrambling activity. Mutational analyses of BSG showed that the atypical glutamic acid in the transmembrane region is required for BSG's association with Xkr8...

BACKGROUND: To improve the quality of Pacific white shrimp (Litopenaeus vannamei), active coating solutions were prepared by dissolving 10 g L(-1) of basil seed gum (BSG) and adding various levels of thymol (6, 8, and 10 % w/w based on gum weight) and glycerol (3.5 g L(-1) ) as plasticizer. The effects of coating solutions (CS1-4) on the quality changes of shrimps during refrigerated storage of 20 days were investigated. RESULTS: Total volatile basic nitrogen (TVB-N) value in shrimp coated with CS4 (containing 10%w/w thymol) was slightly higher than the upper threshold of 300 mg kg(-1) on the 18th day, while that of uncoated shrimp increased to or over the threshold value on the 7th day...

The aim of this study was to investigate the association between a functional variant of the basigin (BSG) gene, caused by a polymorphism (rs11473) at the miR-483-5p binding site, and the risk of esophageal squamous cell carcinoma (ESCC) in the Chinese population. The rs11473 polymorphism was genotyped in 624 esophageal cancer patients and 636 cancer-free age- and gender-matched controls using polymerase chain reaction restriction and direct sequencing. The functional variants resulting from the BSG rs11473 SNP were investigated using a luciferase activity assay and validated by immunoblotting...

Our preliminary study found that CD147 is related to radioresistance and maybe an adverse prognostic factor in cervical cancer. To date, the mechanisms underlying CD147-induced radioresistance in cervical cancer remain unclear. In the present study, we investigated the mechanisms by which CD147 affects radiosensitivity in cervical cancer both in vitro and in vivo. In this study, the clonogenic assay showed that radiosensitivity was significantly higher in the experimental group (the CD147-negative cell lines) than in the control group (the CD147-positive cell lines)...

BACKGROUND: The median survival of patients with diffuse intrinsic pontine glioma (DIPG) remains less than 1 year. The BSG 98 pre-irradiation chemotherapy protocol showed a significant increase in overall survival. In contrast to current treatment strategies, patients did not have to undergo surgical stereotactic biopsy, which can sometimes lead to complications, to be included in this protocol. MATERIALS AND METHODS: We retrospectively reviewed all the cases of DIPG that were treated in our department from September 15, 2004 to September 15, 2014...

Agricultural feedstocks (brewers' spent grain - BSG, corncob - CC, corn husk - CH, wheat straw - WS and Luffa sponge - LS) were pretreated by liquid hot water (LHW) in order to increase cellulose recovery and enzymatic saccharification. LHW-pretreatment resulted in hemicellulose solubilization, and solids enriched in cellulose. Chemical analysis showed different susceptibilities of the feedstocks to LHW-pretreatment and enzymatic hydrolysis. Pretreated feedstocks presented higher crystallinity (determined through X-ray diffraction) and thermal stability (determined through thermogravimetric analysis) than untreated feedstocks...
