Over the past decade we have seen significant changes in the biological characterization and strategies for treatment of mantle cell lymphoma (MCL). MCL is heterogeneous a disease, and so are the people that have it; although guidelines are appropriate, therapeutic approaches must be individualized based on a variety of factors. In this review, we summarize data on the range of therapeutic options, from observation in patients with slowly progressive low-tumor-burden MCL, to bendamustine-based regimens in typical MCL, to high-dose cytarabine-based regimens in young, fit patients...

Glucose oxidase (GOX) can convert glucose into gluconic acid and hydrogen peroxide (H2O2), which is potentially useful for synergistic cancer starving and oxidation therapy. Herein we demonstrate a glucose-responsive nanomedicine of GOX-polymer nanogels to regulate H2O2 production for synergistic melanoma starving and oxidation therapy. GOX-polymer nanogels showed glucose-responsive H2O2-generating activity in vitro, improved stability, and considerably enhanced tumor retention as compared to native GOX. More importantly, they exhibited high anti-melanoma efficacy and no obvious systemic toxicity, whereas native GOX was ineffective and systemically toxic at the same dose...

The healing of chronic wounds remains a considerable challenge in clinical trials and imposes severe financial and physiological burdens on patients. Many works are being tried to find ideal clinical promoting-wound-healing biomaterials. Small bioactive peptides with low cost and easy production, store and transfer become excellent candidates. Here, we identified a novel peptide (named OM-LV20) from skin secretions of odorous frog Odorrana margaretae. The peptide had an amino acid sequence of 'LVGKLLKGAVGDVCGLLPIC', contained an intramolecular disulfide bridge at the C-terminus, and was produced by posttranslational processing of a 71-residue prepropeptide...

Most of the antibiotics are associated with considerable side effects. Gentamicin (GM) is one of the most commonly used antibiotics, but has significant nephrotoxic side effects. Hence, the current study is investigating the beneficial role of camel milk (CM) that ameliorate GM unwanted renal defects and dysfunctions in some experimental animals. Sprague-Dawely rats weighing (200-220g) were divided into groups (four) of six. Group 1 (Control) received normal saline (only). Group 2 was given oral administration of CM at the dose of 5ml/rat/day for fifteen days...

BACKGROUND/AIMS: In evaluating the performance of Phase I dose-finding designs, simulation studies are typically conducted to assess how often a method correctly selects the true maximum tolerated dose under a set of assumed dose-toxicity curves. A necessary component of the evaluation process is to have some concept for how well a design can possibly perform. The notion of an upper bound on the accuracy of maximum tolerated dose selection is often omitted from the simulation study, and the aim of this work is to provide researchers with accessible software to quickly evaluate the operating characteristics of Phase I methods using a benchmark...

Despite a growing number of treatment options, metastatic castrate resistant prostate cancer remains almost universally fatal. Dose individualization ensures patients receive the maximal benefit from each line of treatment potentially leading to improved outcomes, a reduction in quality of life impairment and minimization of premature cessation for avoidable toxicity. Herein, we review drug-specific issues that may be associated with unexpected or unrecognized variations in drug systemic exposure despite the use of protocol doses...

Several randomized controlled trials of anti-estrogens, such as tamoxifen and aromatase inhibitors, have demonstrated up to a 50-65% decrease in breast cancerincidence among high-risk women. Approximately 15% of women, age 35-79 years, in the U.S. meet criteria for breast cancer preventive therapies, but uptake of these medications remain low. Explanations for this low uptake includelack of awareness of breast cancer risk status, insufficient knowledge about breast cancer preventive therapies among patients and physicians, and toxicity concerns...

Recent evidence shows that dopamine D2-like receptor (D2DR) antagonists, such as trifluoperazine and thioridazine, are effective for cancer therapy and inhibition of cancer stem-like cells (CSCs). In this study, we investigated the anti-cancer effects of combination therapy of dexamethasone (DEX) and sulpiride (SUL), an atypical antipsychotic, against drug-resistant and metastatic breast cancers and further explored the underlying mechanisms. Oral administration of SUL (25, 100 mg·kg(-1)·d(-1)) alone did not inhibit the tumor growth in human breast cancer MCF-7/Adr xenograft model, but dose-dependently decreased the proportion of CSCs in vitro and in vivo...

We studied physiological traits and Mn transporter genes expression in ryegrass genotypes (One-50, Banquet-II, Halo-AR1 and Nui) under increasing Mn (2.4-750 μM) at short-term (8-24 h) in nutrient solution. An increment in Mn concentration occurred early in roots of all genotypes at increased Mn doses relative to control. Banquet-II and Nui roots showed the greatest Mn concentration at the highest Mn supply. Net photosynthesis (Pn) of Banquet-II and Halo-AR1 were not perturbed by Mn doses, whereas One-50 and Nui, decayed strongly at the highest Mn dose, concomitant with reduced total chlorophyll concentration...

Although an essential nutrient, manganese (Mn) can be toxic at high doses. There is, however, uncertainty regarding the effects of chronic low-level Mn-exposure. This review provides an overview of Mn-related brain and functional changes based on studies of a cohort of asymptomatic welders who had lower Mn-exposure than in most previous work. In welders with low-level Mn-exposure, we found: 1) Mn may accumulate in the brain in a non-linear fashion: MRI R1 (1/T1) signals significantly increased only after a critical level of exposure was reached (e...

Although copper is an essential micronutrient involved in a variety of biological processes indispensable for sustaining life, it can be toxic when administered in excess. Licorice (Glycyrrhizaglabra) has been used in Chinese folk medicine for the treatment of various disorders. Licorice has the biological capabilities of detoxication, antioxidation, and antiinfection. Here, we test the hypothesis that licorice could ameliorate copper-induced neurotoxic and genotoxic effects in adult male albino rats. For this purpose, 48 adult male albino rats were randomized into five groups: group I (8 rats), untreated control; group II (16 rats), subdivided into; vehicle control IIa (8 rats) which received 1 mL saline twice weekly intraperitoneally for 8 weeks and vehicle control IIb (8 rats) received 0...

Plant phenolics are crucial defense phytochemicals against herbivores and glutathione S-transferase (GST) and carboxylesterase (CarE) in herbivorous insects are well-known detoxification enzymes for such xenobiotics. To understand relationship between a plant phenolic and herbivore GST or CarE genes, we evaluated the relationship between a rice phenolic ferulic acid and resistance to brown planthopper (BPH, Nilaparvata lugens), and investigated the interaction of ferulic acid with GST or CarE genes in BPH. The results indicate that ferulic acid content in tested rice varieties was highly associated with resistance to BPH...

Hemophagocytic Lymphohistiocytosis (HLH) is a life-threatening disorder of immune dysregulation characterized by fever, hepatosplenomegaly, cytopenias, CNS disease, increased inflammatory markers and hemophagocytosis. Currently, allogeneic hematopoietic stem cell transplantation is the only curative approach for patients with HLH with reported survival ranging from 50-70% with myeloablative conditioning (MAC) regimens. However, donor availability and transplant related mortality associated with conventional MAC are major barriers to success...

BACKGROUND: Once-daily aminoglycoside dosing (ODA) is used in most patient populations to optimize antibacterial activity and reduce toxicity. Unfortunately, burn patients are excluded from ODA due to concerns over altered pharmacokinetics resulting in a shortened half-life and low peak aminoglycoside concentrations. Retrospective studies suggest that ODA may be appropriate if higher milligram/kilogram doses are used. However, no prospective clinical trials in burn patients exist to confirm these findings...
