Abstract
Abstract
Objective
In the era of organ shortage, redo liver transplantation (reLT) is frequently discussed in terms of expected poor outcome, high cost and therefore wasteful resources. However, there is a lack of benchmark data to reliably assess outcomes after reLT. The aim of this study was to define the ideal reLT case, and to establish clinically relevant benchmark values for best achievable outcome in reLT.
Methods
We collected data on reLT between January 2010 and December 2018 from 22 high volume transplant centers on three continents. Benchmark cases were defined as recipients with model of end-stage liver disease score <=25, absence of portal vein thrombosis, no mechanical ventilation before surgery, receiving a graft from a donor after brain death. In addition, early reLT including those for primary non-function (PNF) were excluded. Clinically relevant endpoints covering intra- and postoperative course were selected and complications were graded by severity using the Clavien-Dindo classification and the comprehensive complication index (CCI). The benchmark cutoff for each outcome was derived from the 75th percentile of the median values of all benchmark centers, indicating the “best achievable” result. To assess the utility of the newly established benchmark values, we analyzed patients who received reLT for PNF (non-benchmark patients).
Results
Out of 1110 reLT 413 (37.2%) qualified as benchmark cases. Benchmark values included: Length of intensive care unit and hospital stay: <=6 and <=24 days, respectively; Clavien-Dindo grade >=3a complications and the CCI at 1 year: <=76% and <=72.2, respectively; in-hospital and 1-year mortality rates: <=14.0% and <=14.3%, respectively. The cutoffs for transplant-specific complications such as biliary complications at 1 year, outflow problems at 1 year and hepatic artery thrombosis at discharge were <=27.3%, <=2.5% and <=4.8%, respectively. Patients receiving a reLT for PNF showed mean outcome values all outside the reLT benchmark values. In-hospital mortality rate was 34.4% and the mean CCI at discharge 68.8.
Conclusion
ReLT remains associated with high morbidity and mortality. The availability of benchmark values for outcome parameters of reLT may serve for comparison in any future analyses of individuals, patient groups, or centers, but also in the evaluation of new therapeutic strategies and principles.

Abstract
Accelerated soil-nitrifier activity and rapid nitrification are the cause of declining nitrogen-use efficiency (NUE) and enhanced nitrous oxide (N2O) emissions from farming. Biological nitrification inhibition (BNI) is the ability of certain plant roots to suppress soil-nitrifier activity, through production and release of nitrification inhibitors. The power of phytochemicals with BNI-function needs to be harnessed to control soil-nitrifier activity and improve nitrogen-cycling in agricultural systems. Transformative biological technologies designed for genetic mitigation are needed, so that BNI-enabled crop-livestock and cropping systems can rein in soil-nitrifier activity, to help reduce greenhouse gas (GHG) emissions and globally make farming nitrogen efficient and less harmful to environment. This will reinforce the adaptation or mitigation impact of other climate-smart agriculture technologies.

Abstract
In the case of cultivated modern wheats, the variation in zinc and iron concentrations in seeds is relatively small. Moreover, environmental and management factors exert a greater effect on variation of micronutrient concentrations of modern cultivated wheats than genetic factors. Wild wheats might serve as an important source of new genetic material for increasing micronutrient concentrations in seeds. To investigate this, we studied the variation in zinc and iron concentrations in seeds of wild and primitive diploid wheats and wild tetraploid wheats. The variation was particularly large in the case of zinc. The highest concentrations of zinc were found in the seeds of ssp. boeoticum (178 mg/kg) and ssp. dicoccoides (159 mg/kg). The results demonstrate that the genetic variation in the concentrations of zinc and iron in cultivated modern tetraploid and hexaploid wheats is extremely low when compared with the variation found in wild diploid and tetraploid wheats. This suggests that wild wheats, particularly chromosomes 6A and 6B in the wild tetraploid wheats, can be considered a major source of genetic diversity for increasing zinc and iron density in the seeds of modern wheats. In view of the fact that the concentrations of protein in seeds are strongly and positively correlated with the concentrations of iron and particularly of zinc, selection and/or breeding for high zinc and iron levels in seeds may result in simultaneously high levels of protein.

Abstract
Background Resveratrol is a polyphenolic compound commonly found in the
skins of red grapes. Sirtuin 1 (SIRT1) is a human gene that is activated
by resveratrol and has been shown to promote longevity and boost
mitochondrial metabolism. We examined the effect of resveratrol
on normal and osteoarthritic (OA) human chondrocytes. Methods Normal and OA chondrocytes were incubated with various concentrations
of resveratrol (1 µM, 10 µM, 25 µM and 50 µM) and cultured for 24,
48 or 72 hours or for six weeks. Cell proliferation, gene expression,
and senescence were evaluated. Results SIRT1 was significantly upregulated in normal chondrocytes with
resveratrol concentrations of 25 µM and 50 µM on both two- (2D)
(both p = 0.001) and three-dimensional (3D) cultures (p = 0.008
and 0.001, respectively). It was significantly upregulated in OA
chondrocytes treated with 10 µM, 25 µM and 50 µM resveratrol on
2D cultures (p = 0.036, 0.002 and 0.001, respectively) and at 50
µM concentration on 3D cultures (p = 0.001). At 72 hours, the expression
of collagen (COL)-10, aggrecan (AGG), and runt-related transcription
factor 2 (RUNX2) was significantly greater in both 25 µM (p = 0.011,
0.006 and 0.015, respectively) and 50 µM (p = 0.019, 0.004 and 0.002,
respectively) resveratrol-treated normal chondrocyte cultures. In
OA chondrocytes, expression of COL10 and RUNX2 was significantly
greater in 25 µM (p = 0.004 and 0.024) and 50 µM (p = 0.004 and
0.019) cultures at 72 hours on 3D cultures. Conclusions At concentrations of 25 µM and/or 50 µM, resveratrol treatment
significantly upregulates SIRT1 gene expression in normal and osteoarthritic
chondrocytes. Resveratrol induces chondrocytes into a hypertrophic
state through upregulation of COL1, COL10, and RUNX2. Cite this article: Bone Joint Res 2014;3:51–9.

Abstract
Abstract
Background The efficacy and feasibility of chemotherapy in elderly metastatic breast cancer (MBC) patients (pts) have been studied in various phase II studies. However, results of prospective randomized studies in elderly MBC pts are scarce.
Methods In this phase III multicenter study, MBC pts ≥ 65 years eligible for first-line chemotherapy were randomized between pegylated liposomal doxorubicin (PEGdoxo) (45mg/m2, IV, q 4 wks) or capecitabine (Cape) (1000 mg/m2 PO bid, days 1–14, q 3 wks). Other eligibility criteria were ECOG performance status (PS) ≤ 2 (3 allowed if due to pain or pre existing comorbidity), adequate bone marrow and organ functions. Stratification factors were PS (0–1 vs 2–3), HER2 status, visceral/non-visceral disease, adjuvant hormonal therapy (HTx), and HTx for MBC. Baseline geriatric assessment (GA) included functional status, instrumental activities of daily living, cognition, mood, comorbidity, polypharmacy and nutritional status. Chemotherapy was continued for 24 wks in the absence of progressive disease (PD) or unacceptable toxicity. Primary endpoint was progression-free survival (PFS), secondary endpoints were response rate, overall survival (OS), toxicity (CTC criteria) and compliance.
Results Between April 2007 and August 2011, 78 pts were randomized to PEGdoxo (n = 40) or Cape (n = 38). The study was prematurely closed due to slow accrual and supply problems with PEGdoxo. Mean age was 74 years (range 65–86; 75+ 54%; 80+ 13%). Pt characteristics were balanced between the two arms: PS 0–1 77%, ER+ 68%, HER2+ 5%, visceral/non-visceral disease 76%/24%, adjuvant HTx 46%, HTx for MBC 56%, ≥ 3 metastatic sites 50%. Only 22 out of 75 pts with a baseline GA had no geriatric condition (29%), while 32 pts (43%) and 21 pts (28%) had one or ≥ 2 geriatric conditions, respectively. Chemotherapy was given for 6 months in 38%, with a mean dose intensity of 84% in both arms. Reasons for early treatment discontinuation were: PD (31%), toxicity (28%), pt withdrawal (3%). After a median follow up of 32 months, 74 pts had PD and 56 pts had died. The median PFS was 5.7 and 7.7 months with PEGdoxo and Cape (HR 0.68, 95% CI: 0.42–1.11, p = 0.12) and the median OS was 13.8 and 16.8 months, respectively (HR 0.84, 95% CI: 0.49–1.42, p = 0.51). Response was evaluable in 64 pts, with a partial response (PR) in 7 (21%) and 6 pts (19%), and stable disease in 21 (64%) and 17 pts (55%) for PEGdoxo and Cape, respectively. Toxicity was acceptable, mainly being grade 1–2, with for PEGdoxo/Cape grade 1 alopecia in 14/4 pts (grade 2 in 1 PEGdoxo pt), grade 3 fatigue in 5/5 pts, grade 3 HFS in 4/6 pts and grade 3 mucositis in 4/1 pts, respectively. Pts with ≥ 1 geriatric condition more frequently experienced grade 3–4 toxicity, after correcting for type of chemotherapy, age and PS (HR 2.24, 95% CI: 1.21–4.16). Pts aged 75+ had a twofold higher risk of dying, irrespective of treatment arm (HR 2.31, 95% CI: 1.31–4.07).
Conclusions First-line chemotherapy with either PEGdoxo or Cape was feasible in elderly MBC pts, with adequate dose intensity and acceptable toxicity, even in non-fit pts or pts aged 75+. Baseline GA correlated with toxicity.

Abstract
Using three diploid (Triticum monococcum, AA), three tetraploid (Triticum turgidum, BBAA), two hexaploid (Triticum aestivum and Triticum compactum, BBAADD) wheats and two Aegilops tauschii (DD) genotypes, experiments were carried out under controlled environmental conditions in nutrient solution (i) to study the relationships between the rates of phytosiderophore (PS) release from the roots and the tolerance of diploid, tetraploid, and hexaploid wheats and AE: tauschii to zinc (Zn) and iron (Fe) deficiencies, and (ii) to assess the role of different genomes in PS release from roots under different regimes of Zn and Fe supply. Phytosiderophores released from roots were determined both by measurement of Cu mobilized from a Cu-loaded resin and identification by using HPLC analysis. Compared to tetraploid wheats, diploid and hexaploid wheats were less affected by Zn deficiency as judged from the severity of leaf symptoms. Aegilops tauschii showed very slight Zn deficiency symptoms possibly due to its slower growth rate. Under Fe-deficient conditions, all wheat genotypes used were similarly chlorotic; however, development of chlorosis was first observed in tetraploid wheats. Correlation between PS release rate determined by Cu-mobilization test and HPLC analysis was highly significant. According to HPLC analysis, all genotypes of Triticum and AE: tauschii species released only one PS, 2'-deoxymugineic acid, both under Fe and Zn deficiency. Under Zn deficiency, rates of PS release in tetraploid wheats averaged 1 micromol x (30 plants)(-1) x (3 h)(-1), while in hexaploid wheats rate of PS release was around 14 micromol x (30 plants)(-1) x (3 h)(-1). Diploid wheats and AE: tauschii accessions behaved similarly in their capacity to release PS and intermediate between tetraploid and hexaploid wheats regarding the PS release capacity. All Triticum and Aegilops species released more PS under Fe than Zn deficiency, particularly when the rate of PS release was expressed per unit dry weight of roots. On average, the rates of PS release under Fe deficiency were 3.0, 5.7, 8.4, and 16 micromol x (30 plants)(-1) x (3 h)(-1) for AE: tauschii, diploid, tetraploid and hexaploid wheats, respectively. The results of the present study show that the PS release mechanism in wheat is expressed effectively when three genomes, A, B and D, come together, indicating complementary action of the corresponding genes from A, B and D genomes to activate biosynthesis and release of PS.

Abstract
OBJECTIVE To predict blood pressure outside the clinic from a short-term in-hospital registration for patients referred for ambulatory blood pressure monitoring (ABPM) with special attention to office hypertension. PATIENTS AND METHODS A series of measurements of blood pressure was performed by the same technician for 187 patients, 82% of whom were being administered antihypertensive therapy. She performed three mercury measurements of blood pressure (Hg stress 1) and then three manually started measurements with a semi-automatic device (Dinamap 1846SX; Dinamap stress) alternated with three manually started readings with a SpaceLabs 90207 monitor (SpaceLabs stress) on the contralateral non-dominant arm. The in-hospital session was continued with 15 automatic Dinamap registrations at 2 min intervals without the technician being present (Dinamap unstressed, five periods of three measurements averaged) before the patient left the hospital for 24h ABPM. RESULTS The percentages of patients with hypertension in the office (systolic blood pressure >/= 140 mmHg or diastolic blood pressure >/= 90 mmHg, or both) were 80% with Hg stress 1, 76% with Dinamap stress and 85.0% with SpaceLabs stress. Average diastolic SpaceLabs stress was 6.0+/-5.6 mmHg (significantly) higher than diastolic Dinamap stress, whereas the difference between systolic blood pressures was 0.2+/-10.0 mmHg. No further change in blood pressure occurred after the fourth period of Dinamap unstressed measurements. Office hypertension defined as SpaceLabs stress systolic blood pressure >/= 140 mmHg or diastolic blood pressure >/= 90 mmHg, or both, and SpaceLabs daytime systolic blood pressure < 135 mmHg and diastolic blood pressure < 85 mmHg was found in 21 individuals. Office hypertension defined with similar cut-off points in the comparison of Dinamap stress versus Dinamap unstressed period 5 was found in 29 cases, 10 of which overlapped with the definition SpaceLabs stress versus SpaceLabs daytime. The differences between Dinamap stress and Dinamap unstressed period 5 were significantly correlated to the changes of SpaceLabs stress and SpaceLabs daytime both for systolic (r =0.41) and for diastolic (r =0.32) blood pressures. CONCLUSIONS Measurements of blood pressure in the office with various techniques (mercury, Dinamap and SpaceLabs) are not equivalent. Office hypertension cannot be reliably predicted from a short-term semi-automatic in-hospital registration of blood pressure with a Dinamap device.

Abstract
Suppression of the secretion of prolactin, growth hormone and insulin-like growth factor 1 (IGF-1) might be important in the growth regulation and treatment of breast cancer. Because oestrogens may counteract the anti-tumour effects of such treatment, the combination of an anti-oestrogen (tamoxifen), a somatostatin analogue (octreotide) and a potent anti-prolactin (CV 205-502) might be attractive. In this respect, we performed a first exploratory long-term study on the feasibility of combined treatment and possible clear differences in endocrine and anti-tumour effects during such combined treatment vs standard treatment with tamoxifen alone. Twenty-two post-menopausal patients with metastatic breast cancer (ER and/or PR positive or unknown) were randomized to receive either 40 mg of tamoxifen per day or the combination of 40 mg of tamoxifen plus 75 microg of CV 205-502 orally plus 3 x 0.2 mg of octreotide s.c. as first-line endocrine therapy. An objective response was found in 36% of the patients treated with tamoxifen alone and in 55% of the patients treated with combination therapy. Median time to progression was 33 weeks for patients treated with tamoxifen and 84 weeks for patients treated with combination therapy, but the numbers are too small for hard conclusions. There was no difference in overall post-relapse survival between the two treatment arms. With respect to the endocrine parameters, there was a significant decrease of plasma IGF-1 levels in both treatment arms, whereas during combined treatment plasma growth hormone tended to decrease and plasma prolactin levels were strongly suppressed; in some patients insulin and transforming growth factor alpha (TGF-alpha) decreased during the triple therapy. Although there was no significant difference in mean decrease of plasma IGF-1 levels between the two treatment arms, combined treatment resulted in a more uniform suppression of IGF-1. Therefore, the addition of a somatostatin analogue and an anti-prolactin may potentially enhance the efficacy of anti-oestrogens in the treatment of breast cancer owing to favourable endocrine and possible direct anti-tumour effects. Large phase III trials using depot formulations (to increase the feasibility) of somatostatin analogues are warranted to demonstrate the potential extra beneficial anti-tumour effects of such combination therapy.

Abstract
The relevance of quantitative determinations of urinary deoxypyridinolines (DPY) and pyridinolines (PY), and of serum type I collagen carboxyterminal cross-linked telopeptides (ICTP), has been evaluated for patient monitoring in multiple myeloma (MM). In 178 untreated MM patients, a clear correlation was found between ICTP concentrations, bone destructions and serum calcium levels. Furthermore, serum ICTP, urinary DPY and PY concentrations were estimated before and during treatment in a further 33 MM patients randomly allocated to four groups receiving intravenous melphalan/prednisone (MivP) chemotherapy alone, or MivP in combination with three different doses of i.v. clodronate. 1800 mg of i.v. clodronate combined monthly with MivP induced a rapid and sustained reduction in bone resorption parameters to the normal range, a result not obtained with either MivP alone, or with a lower clodronate dose. While confirming the relevance of determining pyridinium cross-links for estimating bone resorption in MM, our data indicate that measurements of these parameters could be useful for dose finding and monitoring of bisphosphonate therapy.

Abstract
This study sought to compare developmental controls in breeding a within two winter wheat improvement programs, one Australian and a CIMMYT/ICARDA program based in West Asia. Developmental controls considered were intrinsic earliness, and responses to photoperiod and to vernalization. The reliability with which each control on development had been measured was tested in separate experiments using the wheats utilized in the Australian program. Measures of intrinsic earliness showed significant agreement between experiments, better agreement being found for response to photoperiod and between integrated response to vernalization and time to double ridge after late summer sowings. The wheats utilized in the CIMMYTI/CARDA programs were found to be quick in intrinsic earliness, and to possess little response to photoperiod. While these controls varied more for the wheats utilized in the Australian program, commercial Australian winter wheats were similar to the CIMMYTI/CARDA lines. Lines utilized by both programs were represented by types with spring, facultative and winter habit. The clearest differences between programs were that CIMMYTI/CARDA winter wheats appeared to have much stronger response to vernalization than the Australian winter wheats. These findings suggest breeders would find a good proportion of segregates, from crosses between the Australian and the CIMMYTI/CARDA winter wheats, to be developmentally adapted to south-central New South Wales. This suggests CIMMYTI/CARDA winter wheats provide a matching pool from which to access germplasm to introduce new characters into Australian winter wheats.

Abstract
406 untreated multiple myeloma patients of stage I (n = 54), II (n = 148) and III (n = 204) were enrolled in the trial. 51/54 stage I and 60/148 stage II patients were asymptomatic and followed without treatment until disease progression (progression free survival: 60% after 4 years for stage I versus 50% after 1 year for stage II). Symptomatic patients of stage I (n = 3/54) and II (n = 88/148) presenting with tumour progression, received melphalan 15 mg/m2 intravenously (i.v.) and prednisone 60 mg/m2 oral days 1-4 (MP). Stage II disease remission rate was 59%, and 50% tumour related survival (TRS) was 59 months. Stage III patients were randomised to receive MP or VBAMDex (vincristine/BCNU/doxorubicin/melphalan/dexamethasone) treatment. 43% of MP treated patients responded compared with 64% of the VBAMDex group. 50% TRS was 36 months in both groups without a detectable difference. 117 responders of stage II and III with stable disease were randomised to receive either IFN-alpha (5 x 10(6) IU, subcutaneous (S.C.) 3 times per week) or no maintenance treatment. The relapse rate in both groups was 50% after 13 months. No survival benefit for IFN alpha treated patients was observed (50% TRS: 45 months).

Abstract
The right sympathetic nerves of perfused rat hearts were stimulated in the presence of inhibitors of neuronal and extraneuronal uptake and propranolol. The inhibition by alpha adrenoceptor agonists of stimulation-evoked (10 pulses, 0.1 Hz) [3H]norepinephrine (NE) overflow into the perfusate was taken as a parameter of presynaptic adrenoceptor activation. Under the present conditions, autoinhibition of NE release is not activated by endogenous NE as evident from ineffectiveness of adrenoceptor antagonists in facilitating evoked [3H]NE overflow. The potency (EC50, -log10), affinity (agonist-presynaptic receptor dissociation constant KA, -log10) and relative efficacies (RE) were determined for phenethylamines (NE or alpha-methylepinephrine) and for imidazoline derivatives. NE (-log EC50, 7.76) was 0.88 log units more potent than alpha-methylepinephrine (-log EC50, 6.88) and about the same difference was observed for the -log KA values (5.92 vs. 4.75). RE were similar (NE, 100%; alpha methylepinephrine, 98%) and 22- to 50-fold higher than efficacies of imidazoline derivatives. Hydroxylations in positions 3 and 4 of the phenyl moiety of phenylaminoimidazoline (-log EC50, less than 5; -log KA, less than 5; RE, less than 1%) resulted in a marked increase in potency (-log EC50, 8.32) of the resulting dihydroxyphenylaminoimidazoline due to a high affinity (-log KA, 8.22) at a low efficacy (2% of NE). In contrast, hydroxylation in positions 3 and 4 of the phenyl ring of tolazoline (no agonist activity under the present conditions; antagonist affinity constant from the literature, 6.4-6.6) produced dihydroxytolazoline, a moderately potent agonist (-log EC50, 7.25) with an efficacy of 3.5% at an affinity (-log KA, 6.92) not much different from that of tolazine.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The effect of exogenous hypercortisolism and 1,25-dihydroxyvitamin D-3 on small-intestinal calcium and glucose transport in the rat was studied at the level of brush-border membrane vesicles generated from isolated villous cells by a freeze-thaw procedure. At 5 X 10(-5) M extravesicular calcium, initial uptake rates in vesicles prepared from triamcinolone-treated adult rats were decreased by 30% after 5 days. Since calcium ionophore A23187 virtually abolished the difference in calcium uptake, triamcinolone appeared to affect calcium channel density or activity rather than intravesicular binding capacity. Kinetic analysis showed that a decrease in Vmax of a saturable calcium transport system could entirely account for the diminished rate of vesicular calcium uptake. Calcium transport rates could be partially restored by in vivo administration of 1,25-dihydroxyvitamin D-3 at a dosage which did not affect vesicular calcium uptake in control animals. Conversely, sodium-driven glucose accumulation in brush-border vesicles from triamcinolone-treated rats was stimulated by 50-70% after 36 h and appeared insensitive to vitamin D. A specific triamcinolone action on the glucose carrier itself rather than on the driving force of the sodium gradient was indicated by (i) a similar stimulation of glucose transport under equilibrium exchange conditions and (ii) an opposite effect of triamcinolone on sodium-driven alanine transport. The triamcinolone-induced changes in calcium and glucose uptake were not accompanied by a gross alteration of membrane integrity in vitro or by major alterations in vesicular protein composition, intravesicular glucose space and sucrase or alkaline phosphatase activity. The modification of vesicular transport properties is discussed in relation to the vitamin D-antagonized inhibition of intestinal calcium uptake and the stimulation of glucose absorption in response to supraphysiologic amounts of glucocorticoids observed in intact epithelium.

Abstract
In a 37-year-old female patient with marked signs of cholestasis and excessive hyperbilirubinaemia without any recognisable cause, the unexpected diagnosis of massive amyloidosis of the peri-collagenous and perireticular type was made after hepatic needle biopsy. There were also amyloid deposits in the rectal mucosa and in the bone marrow. Fifteen months after the onset of disease symptoms the patient died from the consequences of spontaneous intrahepatic haemorrhage. At the post-mortem investigation generalised amyloidosis with massive involvement of nearly all organs was found. Primary amyloidosis should be considered in the differential diagnosis of any aetiologically unexplained cholestasis.

Abstract
In seven patients the diagnosis of hair cell leukaemia (leukaemic reticuloendotheliosis) was confirmed cytochemically and histologically. Splenectomy, in six patients, apparently favourably influenced the course. Isoenzyme 5 of the acid phosphatase was demonstrated in the hairy cells of all patients. Reaction of alpha-naphthylacetate esterase was moderately positive in the hairy cells. Phagocytosis of latex and India-ink particles was demonstrated especially in tartrate-resistant cells of one patient. In two patients eight permanently growing cell lines were demonstrated from leucocytes and defined cytochemically. Capacity for phagocytosis of hairy cells and positive reaction of alpha-naphthylacetate esterase in the hairy cells suggest properties of monocytes. But it is not possible definitively to classify the hairy cells among B-cells or monocytes.
