Abstract
Patients receiving ABO-incompatible (ABOi) kidney transplants are treated before and after transplant with combination therapy, such as intravenous immunoglobulin (IVIG) and therapeutic plasma exchange, to prevent allograft rejection by reducing anti-A and anti-B titers. Although generally considered safe, it is well known that commercial IVIG products contain detectable anti-A and anti-B, which can be associated with hemolysis. Different preparative manufacturing techniques during the production of IVIG affect ABO antibody levels in IVIG preparations; therefore, some manufacturers now use new methods to reduce anti-A/B levels at the preproduction stage. The variations in implementing these strategies creates the potential for significant variation in antibody titers between products and, in some cases, even between lots of the same IVIG product. We report a case of persistently elevated anti-A titers in an ABOi kidney transplant recipient associated with elevated ABO antibody titers present in the preparation of IVIG used at our facility.

Abstract
Abstract
In a recent study, we identified the dephosphorylated form of BimEL as a key death effector of antiestrogen treatment of ER+ breast cancer cells and further showed that MEK1/MAPK1/2 blockade was required to produce high levels of dephosphorylated BimEL, particularly under conditions of insulin like growth factor 1 (IGF1) stimulation (Periyasamy-Thandavan et al., Breast Cancer Res. 14, 2012). Studies by others have identified MEK1/MAPK1/2 activation as essential to autophagy, a catabolic process induced by multiple stresses including ROS, ceramide accumulation, and nutrient deprivation. Autophagy induction results in autophagosome formation, trafficking of damaged proteins and mitochondria to the autophagosomes, and ultimately fusion with the lysosomes resulting in autolysosome formation. The autolysosome and its contents are degraded by the hydrolytic enzymes of the lysosome. Of particular interest to antiestrogen treatment of breast cancer, we and others have shown that pro-survival autophagy facilitates the emergence of antiestrogen resistant breast cancer cells. Thus, we are keenly interested in how MEK1/MAPK1/2 signaling affects pro-survival autophagy and if MEK blockade would be an effective approach toward blocking pro-survival autophagy in ER+ breast cancer cells undergoing hormonal treatment. In this study, we hypothesized that the requirement of MEK1/MAPK1/2 for pro-survival autophagy is due, in part, to its role in blocking the intracellular accumulation of dephosphorylated BimEL. To test this hypothesis, we modulated the expression of dephosphorylated BimEL with either a BimEL cDNA expression vector, siRNA targeting of BimEL, or MEK1 blockade with the small molecule inhibitor U0126 and determined the levels of the autophagic flux in ER+ breast cancer cells undergoing antiestrogen treatment. The determination of autophagic flux was made by comparing the levels of two proteins involved in autophagy -the LC3 /Atg8 and p62 (SQSTM1) proteins- in cell populations undergoing the different treatments in the presence or absence of chloroquine (CQ). The lipidated form of LC3, designated LC3II, is typically increased in cells undergoing autophagy, facilitates the formation of the mature autophagosomal membranes, and is subsequently degraded in the autolysosome. The p62 protein is required for the delivery of ubiquitinated protein complexes to the autophagosome and is degraded along with the ubiquitinated complex of proteins. CQ is a lysosomotrophic agent routinely used in autophagic flux assays because it blocks the turnover of autolysosomes with accumulation of LC3 II and p62, allowing the total levels of LC3II and p62 to be ascertained under all treatment conditions. These studies showed that siRNA targeting of BimEL increased basal and tamoxifen-induced autophagy in ER+ MCF-7 breast cancer cells. In contrast, the overexpression of dephosphorylated BimEL led to an increase in LC3 II and p62 levels due to a significant attenuation of autophagic flux (approximately 50%) in antiestrogen-treated cell populations. Current studies are focused on the mechanism of BimEL-mediated blockade of pro-survival autophagy, with the long term goal of optimizing this “downstream effector” function of MEK1/MAPK1/2 blockade in ER+ breast cancer cells for improved therapeutic outcome.

Abstract
We developed a microfluidic chip setup for capillarity-assisted particle assembly (CAPA). A capillary bridge is formed between the aperture of a silicon chip and the assembly template. The bridge is fed with particle suspension through a microfluidic channel on the chip top side. With this setup, we can control the particle assembly location and tune the suspension composition during particle assembly. In this note, we describe the chip setup, the CAPA process using the microfluidic chip, and results of complex particle assemblies, such as composite particle arrays and particle gradients, that could not be obtained using a conventional CAPA setup.

Abstract
Spent mushroom compost (SMC), a byproduct of commercial mushroom cultivation, poses serious environmental problems that have hampered the growth of this important agro-industry. In an effort to develop new applications for SMC, we explored its use as a feedstock for bioethanol production. SMC constitutes approximately 30%w/w polysaccharides, 66% of which is glucan. Following dilute-acid pretreatment and enzymatic hydrolysis, both in the presence of PEG 6000, 97% of glucan and 44% of xylan in SMC were converted into the corresponding monosaccharides. Incorporation of PEG 6000 reduced the cellulase requirement by 77%. Zwittergent 3-12 and 3-14 also significantly increased the efficacy of acid pretreatment and enzymatic hydrolysis. The use of SMC in bioethanol production represents a potential mitigation solution for the critical environmental issues associated with the stockpiling of the major byproduct of the mushroom industry.

Abstract
We recently reviewed the status of peptide and nonpeptide agonists and antagonists for the V(1a), V(1b) and V(2) receptors for arginine vasopressin (AVP) and the oxytocin receptor for oxytocin (OT). In the present review, we update the status of peptides and nonpeptides as: (i) research tools and (ii) therapeutic agents. We also present our recent findings on the design of fluorescent ligands for V(1b) receptor localisation and for OT receptor dimerisation. We note the exciting discoveries regarding two novel naturally occurring analogues of OT. Recent reports of a selective VP V(1a) agonist and a selective OT agonist point to the continued therapeutic potential of peptides in this field. To date, only two nonpeptides, the V(2) /V(1a) antagonist, conivaptan and the V(2) antagonist tolvaptan have received Food and Drug Administration approval for clinical use. The development of nonpeptide AVP V(1a), V(1b) and V(2) antagonists and OT agonists and antagonists has recently been abandoned by Merck, Sanofi and Pfizer. A promising OT antagonist, Retosiban, developed at Glaxo SmithKline is currently in a Phase II clinical trial for the prevention of premature labour. A number of the nonpeptide ligands that were not successful in clinical trials are proving to be valuable as research tools. Peptide agonists and antagonists continue to be very widely used as research tools in this field. In this regard, we present receptor data on some of the most widely used peptide and nonpeptide ligands, as a guide for their use, especially with regard to receptor selectivity and species differences.

Abstract
BACKGROUND Duloxetine was found safe and effective in the treatment of moderate to severe female stress urinary incontinence (SUI) in controlled clinical trials; complementary data from routine clinical practice are still wanted. OBJECTIVES To explore the use of various initial duloxetine doses by physicians in the treatment of female SUI in routine clinical practice and its implications on drug safety and patients' subjective impression of effectiveness. METHODS Adult women treated with duloxetine for SUI symptoms were documented as part of an ongoing large-scale observational study in Germany. Data collected at baseline, after 4 and 12 weeks, were evaluated by initial doses. Statistics were descriptive, 95% confidence intervals were calculated for adverse event (AE) rates. RESULTS A total of 7888 adult women were treated with duloxetine; their mean age was 61.4 years, body mass index 27 kg/m(2), incontinence episode frequency (IEF) 14.0 per week. Previous SUI treatments were observed in 52.2%, comorbidities in 60.4% of the patients. A total of 90.7% reported reduced frequency of SUI-episodes, 12.1% any AE; nausea (5.7%) and vertigo (1.6%) were reported most frequently. In all, 52.2% of patients were initiated on a duloxetine dose of 40 mg/day. Only minor differences in patient characteristics, effectiveness and tolerability were associated with varying initial duloxetine doses. CONCLUSIONS Many women received lower duloxetine doses than expected based on evidence-based dosing recommendations. Although SUI patients in this study had a higher health risk because of old age and multiple comorbidities than in previous controlled clinical trials, AE rates were lower, possibly because of the observational character of the study and/or the use of rather low doses. Similar AE rates for varying initial doses possibly reflect sensible dose-adjustment to individual needs.
