3) to 16.0% (3.8) after 3 years (p=0.02). In patients without baseline hypertrophy, LVM index and MFS remained stable. Mean yearly fall in estimated glomerular filtration rate versus baseline after 5 years of enzyme replacement therapy was -3.17 mL/min per 1.73 m(2) for men and -0.89 mL/min per 1.73 m(2) for women. Average pain, measured by Brief Pain Inventory score, improved significantly, from 3.7 (2.3) at baseline to 2.5 (2.4) PLX4032 mw after 5 years (p=0.0023). Quality of life, measured by deviation scores from normal EuroQol values, improved significantly, from -0.24 (0.3) at baseline to -0.17 (0.3)

after 5 years (p=0.0483). Findings were confirmed by sensitivity analysis. No unexpected safety concerns were identified.

Interpretation By comparison with historical natural history data for patients with Fabry’s disease who were not treated with enzyme replacement

therapy, long-term treatment with agalsidase alfa leads to substantial Elafibranor and sustained clinical benefits.”
“Background Mexico’s conditional cash transfer programme, Oportunidades, was started to improve the lives of poor families through interventions in health, nutrition, and education. We investigated the effect of Oportunidades on children almost 10 years after the programme began.

Methods From April, 1998, to October, 1999, low-income communities were randomly assigned to be enrolled in Oportunidades immediately (early treatment, n=320) or 18 months later (late treatment, n=186). In 2007, when 1093 children receiving early treatment and 700 late treatment

in these communities were aged 8-10 years, they were assessed for outcomes including physical growth, cognitive and language development, and socioemotional development. The primary objective was to investigate outcomes associated with an additional 18 months in the programme. We used cluster-adjusted t tests and multivariate regressions to compare effects of programme participation for height-for-age, body-mass index (BMI), and cognitive language and behavioural assessment scores in early versus late treatment groups.

Findings Early enrolment reduced behavioural problems for all children in the early versus late treatment group (mean behaviour problem score -0.09 [SD 0.97] vs 0.13 [1.03]; p=0.0024), but we LCL161 purchase identified no difference between groups for mean height-for-age Z scores (-1.12 [0.96] vs -1.14 [0.97]; p=0.88), BMI-for-age Z scores (0.14 [0.99] vs 0.17 [1.06]; p=0.58), or assessment scores for language (98.8 [13.8] vs 98.4 [14.6] p=0.90) or cognition (98.8 [12.9] vs 100.2 [13.2]; p=0.26). An additional 18 months of the programme before age 3 years for children aged 8-10 years whose mothers had no education resulted in improved child growth of about 1.5 cm assessed as height-for-weight Z score (beta 0.23 [0.023-0.44] p=0.029), independently of cash received.

Interpretation An additional 18 months in the Oportunidades programme has independent beneficial effects other than money, especially for women with no formal education.

Initial TASC classification was highly predictive of first anatomic failure (P < .0001), but it did not predict the durability of subsequent catheter based reintervention (P = .32). Ten patients with stent failure required operation, and five underwent amputation; all had failed with occlusion. Overall limb salvage was 89% and pen-procedural mortality Selleck Verteporfin was 0.4%.

Conclusions: Following primary stenting of the superficial femoral artery (SFA) and popliteal artery,

lesions classified as TASC C or D are more likely to fail with occlusion, lose run-off vessels, and alter the site of subsequent open operation than their TASC A and B counterparts. Although these complications are infrequent, they may negatively impact later attempts at revascularization, and this must be considered when deciding upon the proper treatment strategy for patients with infrainguinal occlusive disease.

“Background:

Peripheral arterial disease (PAD) is one of the serious complications in patients on hemodialysis (HD) therapy. However, arterial calcification of lower limbs’ arteries and its impact on the prevalence and severity of PAD has never been quantitatively evaluated in HD patients with PAD.

Methods: Ninety-seven HD patients were enrolled to evaluate calcification score in superficial femoral artery (SFACS) and below-knee arteries DNA Damage inhibitor (BKACS) quantitatively by 64-row multidetector computed tomography as well as ankle-brachial pressure index (ABI), toe-brachial pressure index (TBI), and clinical and laboratory parameters.

Results: Forty-six patients (47.2%) had PAD, and 11 patients had critical limb ischemia (CLI). SFACS and BKACS were significantly associated click here with the prevalence and severity of PAD, and receiver-operating characteristic analysis showed that SFACS and BKACS well predicted the prevalence of PAD and CLI in HD patients. The independent associating factors for PAD were BKACS

and low TB’ (r(2) = 0.534; P < .0001). Low TBI was also an independent associating factor for CLI (r(2) = 0.245; P < .0001). Multivariate analysis indicated that the independent associating factors for TBI in HD patients were BKACS and C-reactive protein (CRP; r(2) = 0.358; P = .006).

Conclusions: Present quantitative analysis clearly provided the first evidence that arterial calcification of lower limbs’ arteries was closely associated with the prevalence and severity of PAD in HD patients. Furthermore, arterial calcification of below-knee arteries and micro-inflammation represented as CRP were the independent associating factors for low TBI, which was the independent associating factor for PAD and CLI in HD patients.

“Objective: The optimal method of operative management of complex branch renal artery aneurysms (RAAs) remains unclear, with recent reports predominantly espousing endovascular and ex vivo repair.

AKV is an endogenous retrovirus that is involved in causing a high incidence of thymic lymphoma in AKR mice. A comparative analysis of several mouse strains revealed a relatively low level of APOBEC3 expression in AKR mice. Here we show that endogenous mouse APOBEC3 restricts AKV infection and that this restriction likely reflects polymorphisms affecting APOBEC3 abundance rather than differences in the APOBEC3 isoforms expressed. We also observe that restriction of AKV by APOBEC3 is accompanied by G -> A hypermutations in the viral genome. CHIR-99021 Our findings demonstrate that APOBEC3 acts as a restriction factor in rodents affecting the strain

tropism of AKV, and they provide good support for the proposal that APOBEC3-mediated hypermutation contributed to the evolution of endogenous

rodent retroviral genomes.”
“Heme oxygenase (HO), the main enzyme deputed to heme metabolism, has been identified as two main isoforms AZD4547 cell line called HO-1 and HO-2 both present in the central nervous system. Heme oxygenase has been shown to regulate the hypothalamic release of neuropeptides such as corticotrophin-releasing hormone and arginin-vasopressin. The aim of this study was to investigate and further characterize the presence of HO in gonadotropin-releasing hormone (GnRH) secreting hypothalamic neurons, GT1-7 and the role of HO by-products on GnRH secretion. The pulsatile release of GnRH from scattered hypothalamic neurons is the key regulator of mammalian fertility in the

central nervous system. GT1-7 cells are immortalized hypothalamic neurons, characterized by spontaneous electrical activity and pulsatile GnRH release, resembling the central control pathway of the hypothalamic pituitary gonadal axis (HPG) in mammals. Hemin, the substrate of HO, significantly stimulated HO activity in static cultures, causing a rapid increase in GnRH release. Neither biliverdin nor bilirubin were able to mimic this rapid stimulatory effect, which was instead caused by carbon monoxide. Evidence of a possible involvement of prostaglandin E(2) in the HO by-product modulated GnRH secretion was reported. The hemin-evoked effect on GT1-7 neurons suggests a direct activity of HO by-products on the hypothalamic Levetiracetam neuropeptide secretion, and claims for a possible role of CO in both the modulation of gonadotropin secretion and crosstalk among HPG and stress axis within the mammalian hypothalamus.

“We previously identified a novel insect picorna-like virus, termed Kakugo virus (KV), obtained from the brains of aggressive honeybee worker bees that had counterattacked giant hornets. Here we examined the tissue distribution of KV and alterations of gene expression profiles in the brains of KV-infected worker bees to analyze possible effects of KV infection on honeybee neural and physiological states.

Animals received https://www.selleckchem.com/products/lonafarnib-sch66336.html either of the following treatments: (1) saline for 21 days (control group), (2) saline for 20 days and citalopram or DMI for 1 day (citalopram or DMI acute groups), (3) citalopram or DMI for 21 days (citalopram or DMI chronic groups). Somatostatin levels were determined by radioimmunoassay. [(125)I]LTT SRIF-28 binding in the absence (labeling of sst(1-5)) or presence of 3 nM MK678 (labeling of sst(1/4)) and [(125)I]Tyr(3) octreotide (labeling of sst(2/5)) binding with subsequent autoradiography was performed in brains of rats treated with both antidepressants.

Somatostatin levels were increased after citalopram, but not DMI administration, in the caudate-putamen, hippocampus, nucleus accumbens, and prefrontal cortex. Autoradiography studies BAY 63-2521 ic50 illustrated a significant decrease in receptor density in the superficial and deep layers of frontal cortex (sst(2)), as well as a significant increase in the CA1 (sst(1/4)) hippocampal field in brains of chronically citalopram-treated animals. DMI administration increased sst(1/4) receptors levels in

the CA1 hippocampal region. These results suggest that citalopram and to a lesser extent DMI influence the function of the somatostatin system in brain regions involved in the emotional, motivational, and cognitive aspects of behavior.”
“Objectives: Experiments were designed to determine if salivary gland homogenates (SGH) of

the sand fly Lutzomyia longipalpis, the vasodilatory peptides maxadilan and pituitary adenylate cyclase-activating peptide (PACAP-38) may cause plasma leakage and to what extent these effects could be due to PAC1 receptor stimulation. Methods: Using FITC-dextran as a plasma marker, intravital microscopy of the hamster cheek pouch (HCP) and a digital camera were used to assess arteriolar diameter and fluorescence of a selected area (5 mm(2)) representative of the HCP microcirculation. Results: Cheek pouches prepared for intravital Ilomastat microscopy and exposed to topical application of SGH, maxadilan or PACAP-38 developed maximal dilation of arterioles in the range of 20-60 mu m within 10 min, and this effect lasted for 30-90 min. The increase in fluorescence intensity induced by each of these compounds was due to plasma leakage from postcapillary venules. The mutant peptide of maxadilan (M-65), a PAC1 receptor antagonist, inhibited both dilation and plasma leakage induced by SGH or maxadilan. Plasma leakage induced by SGH was modestly inhibited by the bradykinin B(2) receptor antagonist HOE-140, but not by the antihistamine mepyramine or the nitric oxide synthase inhibitor L-NA. Conclusions: SGH of L. longipalpis and its vasodilatory peptide maxadilan caused long-lasting arteriolar dilation and plasma leakage in the cheek pouch via PAC1 receptor activation.

Notably, Nedd4-1 remediation of HIV-1 PTAP(-) budding defects is independent of cellular Tsg101, implying that Nedd4-1′s function in HIV-1 release does not involve ESCRT-I components and is therefore distinct from that of Nedd4-2. Consistent with this finding, learn more deletion of the p6 region decreased Nedd4-1-Gag interaction, and disruption of the LYPXnL motif eliminated Nedd4-1-mediated restoration of HIV-1 PTAP(-). This result indicated that both Nedd4-1 interaction with Gag and function in virus release occur through the Alix-binding LYPXnL motif. Mutations of basic residues located in the NC domain of Gag that are critical for Alix’s facilitation of HIV-1 release, also disrupted release

mediated by Nedd4-1, further confirming a Nedd4-1-Alix functional

interdependence. In fact we found that Nedd4-1 binds Alix in both immunoprecipitation and yeast-two-hybrid assays. In addition, Nedd4-1 requires its catalytic activity to promote virus release. Remarkably, RNAi knockdown of cellular Nedd4-1 eliminated Alix Angiogenesis chemical ubiquitination in the cell and impeded its ability to function in HIV-1 release. Together our data support a model in which Alix recruits Nedd4-1 to facilitate HIV-1 release mediated through the LYPXnL/Alix budding pathway via a mechanism that involves Alix ubiquitination.”
“All lentiviruses except equine infectious anemia virus (EIAV) use the small accessory protein Vif to counteract the restriction activity of the relevant APOBEC3 (A3) proteins of their host species. Prior studies have suggested that the Vif-A3 interaction Dichloromethane dehalogenase is species specific. Here, using the APOBEC3H (Z3)-type

proteins from five distinct mammals, we report that this is generally not the case: some lentiviral Vif proteins are capable of triggering the degradation of both the A3Z3-type protein of their normal host species and those of several other mammals. For instance, SIV(mac) Vif can mediate the degradation of the human, macaque, and cow A3Z3-type proteins but not of the sheep or cat A3Z3-type proteins. Maedi-visna virus (MVV) Vif is similarly promiscuous, degrading not only sheep A3Z3 but also the A3Z3-type proteins of humans, macaques, cows, and cats. In contrast to the neutralization capacity of these Vif proteins, human immunodeficiency virus (HIV), bovine immunodeficiency virus (BIV), and feline immunodeficiency virus (FIV) Vif appear specific to the A3Z3-type protein of their hosts. We conclude, first, that the Vif-A3Z3 interaction can be promiscuous and, second, despite this tendency, that each lentiviral Vif protein is optimized to degrade the A3Z3 protein of its mammalian host. Our results thereby suggest that the Vif-A3Z3 interaction is relevant to lentivirus biology.”

“In the present study, a biologically plausible neuronal population model is developed, which considers functional outcome of neuron-astrocyte interactions.

Based on established neurophysiologic findings, astrocytes dynamically regulate the synaptic transmission of neuronal networks. The employed structure is based on the main physiological and anatomical features of the CA1 subfield of the hippocampus. Utilizing our model, we demonstrate that healthy astrocytes provide appropriate feedback control in regulating neural activity. In this way, the astrocytes compensate the increase of excitation coupling strength among neurons and stabilize the normal level of synchronized behavior. Next, malfunction of astrocytes in the regulatory feedback loop is investigated. In this way, pathologic astrocytes are no longer check details able to regulate and/or compensate the excessive increase of the excitation level. Consequently, disruption of astrocyte signaling initiates hypersynchronous

firing of neurons. LY2874455 nmr Our results suggest that diminishing of neuron-astrocyte cross-talk leads to an abnormal synchronized neuronal firing, which suggests that astrocytes could be a proximal target for the treatment of related disorders including epilepsy.

“Although signs of empathy have now been well documented in non-human primates, only during the past few years have systematic observations suggested that a primal form of empathy exists in

rodents. Thus, the study of empathy in animals has started in earnest. Here we review recent studies indicating that rodents are able to share states of fear, and highlight how affective neuroscience approaches to the study of primary-process emotional systems can help to delineate how primal empathy is constituted in mammalian brains. Cross-species evolutionary approaches to understanding the neural circuitry see more of emotional ‘contagion’ or ‘resonance’ between nearby animals, together with the underlying neurochemistries, may help to clarify the origins of human empathy.”
“Background. Little is known about the epidemiology of bulimia nervosa outside clinical settings. We report the incidence, prevalence and outcomes of bulimia nervosa using for the first time a nationwide Study design.

Method. To assess the incidence and natural course and outcomes of DSM-IV bulimia nervosa among women from the general Population, women (n = 2881) from the 1975-79 birth cohorts of Finnish twins were screened for lifetime eating disorders using 3 two-stage procedure consisting of a questionnaire screen and the Structured Clinical Interview for DSM-IV (SCID).

A prosopagnosic subject with right medial occipitotemporal damage sparing areas in the lateral fusiform gyrus performed well on both tasks.

“Aims:

The aim of our study was

to investigate indoor air quality (IAQ) by comparing pyrogen concentration selleck inhibitor and microbiological contamination in offices in public buildings.

Methods and Results:

Air samples were collected during cold and warm seasons in 39 offices in four European cities. Pyrogens were measured by

the in vitro pyrogen test (IPT), moulds and bacteria by classical microbiology. In 92% of the investigated offices, pyrogen and microbial contaminations were below NCT-501 ic50 150 EEU m-3 and 103 CFU m-3, respectively, whilst in 75%, moulds did not exceed 102 CFU m-3.

Conclusions:

The IPT is a rapid, reliable tool for measuring pyrogens that could be used as an ‘early warning’ indicator of IAQ.

Significance and Impact of the Study:

This is the first study on pyrogenic compound detection in offices using IPT, which could serve for developing future indoor air guidelines.”
“Experience-dependent alterations in the human brain’s white-matter microstructure occur in early adulthood, but it is unknown whether such

plasticity extends throughout life. We used cognitive training, diffusion-tensor imaging (DTI), and structural MRI to investigate plasticity of the white-matter tracts that connect the left and right hemisphere of the frontal lobes. Over a period of about 180 days, 20 younger adults and 12 older adults trained for a total of one hundred and one 1-h sessions on a set of three working memory, three episodic memory, and six perceptual speed tasks. Control groups were assessed at pre- and post-test. Training affected VX-661 several DTI metrics and increased the area of the anterior part of the corpus callosum. These alterations were of similar magnitude in younger and older adults. The findings indicate that experience-dependent plasticity of white-matter microstructure extends into old age and that disruptions of structural interhemispheric connectivity in old age, which are pronounced in aging, are modifiable by experience and amenable to treatment.

“Aim:

The aim of this study was to find suitable yeast isolates as potential microbial feed additives for ruminants.

Methods and Results:

Yeast isolates from traditional fermented food (tapai) and home-made wine were selected based on their tolerance to volatile fatty acids (VFA) mixture of acetic, propionic and butyric acids and to pH and temperature according to the rumen condition.

Results The mean rCBV of meningothelial, fibrous, SU5402 datasheet angiomatous, and anaplastic meningiomas in tumoral parenchyma were 6.93 +/- 3.75, 5.61 +/- 4.03, 11.86 +/- 1.93, and 5.89 +/- 3.85, respectively, and in the peritumoral edema 0.87 +/- 0.62, 1.38 +/- 1.44, 0.87 +/- 0.30, and 3.28 +/- 1.39, respectively. The mean rCBV in tumoral parenchyma of angiomatous meningiomas and in the peritumoral edema of anaplastic meningiomas were statistically different (p < 0.05) from the other types of meningiomas.

Conclusion Perfusion MR imaging can provide useful functional information on meningiomas and help in the preoperative diagnosis of some subtypes of meningiomas.”
“We previously showed that a local

immune response largely composed of type 1 T cells correlated with a favorable outcome of the peritonitis associated with peritoneal dialysis. To clarify how these subsets are recruited to the peritoneal cavity during inflammation, we measured integrin-mediated interactions between the T cells and human peritoneal mesothelial cells. Direct microscopy FRAX597 showed that lipopolysaccharide or peritoneal dialysis effluent stimulated the adherence of T cells to mesothelial cells, a process mediated by the integrins alpha 6 beta 1 and alpha 4 beta 1. Further, the migration of Th1 cell across human mesothelial

cell monolayers grown on transwell surfaces was reduced by anti-alpha 6 beta 1 integrin antibody while that of Th2 cell was inhibited by an anti-alpha 4 integrin antibody. Pretreatment with either lipopolysaccharide or rapid response peritoneal dialysis effluent stimulated T cell migration and this was significantly decreased by the alpha 6 beta 1 compared to the alpha 4 antibody. These results suggest that integrins Selleck ZD1839 may play an important role in mediating selective T cell subset adhesion and migration across human peritoneal mesothelial cell

monolayers and differential integrin expression and selective T cell subset recruitment during peritonitis may affect outcome.”
“Introduction Follow-up of intracranial aneurysms treated by embolisation with detachable coils is mandatory to detect a possible recanalisation. The aim of this study was to compare contrast-enhanced magnetic resonance angiography (CE-MRA) with digital substraction angiography (DSA) used to detect aneurysm recanalisation to determine if DSA is still needed during follow-up.

Materials and methods From May 2006 to May 2007, 55 patients with 67 aneurysms were treated by endosaccular coiling with (n=9) or without (n=58) an adjunctive stent. Follow-up imaging protocol included MRA at 6 and 12 months and a DSA at 12 months or earlier if a major recanalisation was identified on the 6-month MRA. Two neuroradiologists independently reviewed MRA images (readers 1 and 2) and two other reviewed DSA images.

Results Follow-up DSA showed stability of the aneurysm occlusion in 52 cases, recanalisation in 14 cases, and further thrombosis in one.

METHODS: Thirty individuals (age, 64-88 years) with progressive deformity (coronal Cobb angles > 25 degrees and < 85 degrees), intractable back pain, radiculopathy, or neurogenic claudication were treated by less invasive decompression and fusion (unilateral transforaminal interbody

cage instrumentation and bilateral facet fusions) with recombinant human bone morphogenetic protein-2, spanning 3 to 8 segments (average, 6 segments), using biplanar fluoroscopy or intraoperative computed tomography (iCT)-based navigation. Accuracy of screw placement, curve correction, and fusion rate were evaluated during a mean follow-up of 19.6 months.

RESULTS: With 415 screws implanted, misplacement (grade II or greater) was not observed, and no implants required revision. Spinal iCT with automated registration Bafilomycin A1 mw required 17.5 +/- 8.5 minutes (single registration LY2109761 mw for all segments); monosegmental bilateral screw insertion required 6.8 +/- 3.4 minutes. Mean sagittal (coronal) Cobb angle correction was 44.8 +/- 10.7 degrees (31.7 +/- 13.7 degrees).

Mean lumbar lordosis increased from 8.8 +/- 8.9 degrees to -36 +/- 6.9 degrees, and sagittal balance was reduced from 31.6 +/- 15.2 to 8 +/- 8.4 mm. Solid fusion was confirmed in 90% of instrumented segments at 16 months. Average radiation dose to the surgeon was 0.025 mSv for single-level transforaminal lumbar interbody fusion with fluoroscopic guidance vs 0 mSv with iCT navigation.

CONCLUSION: Instrumented LGX818 molecular weight correction of adult deformity was significantly facilitated by iCT navigation, eliminating radiation exposure

to the surgeon. Intraoperative biplanar CT scout views including pelvis and shoulders allow comprehensive assessment of multiplanar deformity correction. Fusion rates obtained with less invasive access equal those of conventional open technique.”
“Existing equations to calculate the estimated glomerular filtration rate (eGFR) were derived from nondiabetic Caucasian patients with chronic kidney disease. Here, we developed formulas to more accurately predict the eGFR in Chinese patients with type 2 diabetes and validated their performance in 202 type 2 diabetic and 46 nondiabetic individuals. Within the diabetic cohort, 135 were randomly assigned to a training group, whereas the remaining 67 diabetic and all of the nondiabetic patients were assigned to a validation group. Reference GFR was measured by (51)Cr-EDTA plasma clearance. The new eGFR-estimating formulas, derived using a stepwise regression model, were compared with existing prediction equations in the validation group. The formulas are: 313 x (Age) – 0.494 (years) x [SCr] – 1.059 (mg/dl) x [Alb] + 0.485 (g/dl) for men, and 783 x (Age) – 0.489 (years) x [SCr] – 0.877 (mg/dl) x [SUN] – 0.150 (mg/dl) for women.

KDOQI encourages AVF creation in order to increase AVF use for dialysis, but the strategy of simply increasing the number being created may not lead to the desired result and potentially lead to an increase in catheter

“Polychlorinated biphenyls (PCBs) are ubiquitous environmental contaminants that have been demonstrated to be toxic to the dopamine (DA) systems of the central nervous system. One proposed mechanism for PCB-induced DA neurotoxicity is inhibition PRN1371 order of the vesicular monoamine transporter (VMAT); such inhibition results in increased levels of unsequestered DA and DA metabolism leading to oxidative stress. We have used an organotypic co-culture system of developing rat striatum and ventral mesencephalon (VM) to determine whether alterations in the vesicular storage of DA, resulting from PCB exposure and consequent induction of oxidative stress, leads to GABA and DA neuronal dysfunction. Twenty-four-hour exposure to an environmentally relevant mixture of PCBs reduced tissue DA and GABA concentrations, increased medium levels of DA and measures of oxidative stress in both the striatum and VM. Alterations in neurochemistry and increases in measures of oxidative stress were blocked in the presence of n-acetylcysteine (NAC). Although NAC treatment did not alter PCB-induced changes in DA neurochemistry,

SBI-0206965 concentration it did protect against reductions in GABA concentration. To determine whether alterations in the vesicular storage of DA were responsible for PCB-induced oxidative stress and consequent reductions in GABA levels, we depleted DA from the co-cultures using alpha-methyl-p-tyrosine (AMPT). AMPT reduced striatal and VM DA levels by 90% and 70%, respectively.

PCB exposure, following DA depletion, neither increased levels of oxidative stress nor resulted in GABA depletion. These results suggest that PCB-induced alterations in the vesicular storage of DA, resulting in increased levels of unsequestered DA, leads to increased oxidative stress, depletion of tissue glutathione, and consequent reductions in tissue GABA concentrations.

“Background: Fosbretabulin Cold-induced injury to various cell types has been shown to be mediated predominantly by chelatable iron. For endothelial cells, this type of injury has so far only been shown in cultured cells. Hypothesizing that this iron-dependent cold-induced injury might also occur in the endothelium of intact vessels, we here set out to optimize the hypothermic storage of blood vessels.

Methods: Segments of porcine aorta were stored for 2 to 21 days in histidine-tryptophan-ketoglutarate (HTK) solution or in modified solutions with or without the iron chelators deferoxamine or LK 614 at 4 C. Parts of the segments were assayed immediately after cold storage, the other parts after subsequent rewarming.
