The cold shock response leads to a growth block and overall repression of translation; however, there is the induction of a set of specific proteins that help to tune cell metabolism and readjust it to the new conditions. For a mesophile like E. coli, the adaptation process takes about 4 h. Although the bacterial cold shock response was discovered over two decades ago we are still far from understanding this process. In this review, we aim Volasertib mw to describe current knowledge, focusing on the functions of RNA-interacting proteins and RNases
involved in cold shock adaptation.”
“The genetic parameters for Brahman cattle under the tropical conditions of Mexico are scarce. Therefore, heritabilities, additive direct and maternal correlations, and genetic correlations for birth weight (BW) and 205 days adjusted weaning weight (WW205) were estimated in four Brahman cattle herds in Yucatan, Mexico. Parameters were estimated fitting a bivariate
animal model, with 4,531 animals in the relationship matrix, of which 2,905 had BW and 2,264 had WW205. The number of sires and dams identified for both traits were 122 and 962, respectively. Direct Z-DEVD-FMK cost heritability estimates for BW and WW205 were 0.41 +/- 0.09 and 0.43 +/- 0.09, and maternal heritabilities were 0.15 +/- 0.07 and 0.38 +/- 0.08, respectively. Genetic correlations between direct additive and maternal genetic effects for BW and WW205 were -0.41 +/- 0.22 and -0.50 +/- 0.15, respectively. The direct genetic, maternal, and phenotypic correlations between BW and WW205 were 0.77 +/- 0.09, 0.61 +/- 0.18, and 0.35, respectively. The moderate to high genetic parameter estimates suggest that genetic improvement by selection is possible for those traits. The maternal effects and their correlation with direct effects should be taken into account to reduce bias in genetic evaluations.”
“Multiple myeloma, the second most common hematological
cancer, is currently incurable due to refractory disease relapse and development of multiple drug resistance. We and others recently established the biophysical model Smoothened Agonist clinical trial that myeloma initiating (stem) cells (MICs) trigger the stiffening of their niches via SDF-1/CXCR4 paracrine; The stiffened niches then promote the colonogenesis of MICs and protect them from drug treatment. In this work we examined in silico the pharmaceutical potential of targeting MIC niche stiffness to facilitate cytotoxic chemotherapies. We first established a multi-scale agent-based model using the Markov Chain Monte Carlo approach to recapitulate the niche stiffness centric, pro-oncogenetic positive feedback loop between MICs and myeloma-associated bone marrow stromal cells (MBMSCs), and investigated the effects of such intercellular chemo-physical communications on myeloma development.

“To evaluate the results of emergency embolisation in acute arterial bleeding of the gastrointestinal tract with a liquid polyvinyl alcohol copolymer from two centres.\n\nWe retrospectively analysed 16 cases (15 patients) of acute arterial bleeding of the gastrointestinal tract where emergency embolotherapy was performed by using the copolymer when acute haemorrhage was not treatable with endoscopic techniques alone. Cause of haemorrhage and technical and clinical success were documented.\n\nArterial Cilengitide embolotherapy was successful in all 16 cases. The technical success rate was 100%.
The cause of bleeding was pancreatitis in four, graft-versus-host disease (GVHD) of the colon in three, malignancy in three, angiodysplasia in two, ulcer in two and panarteritis nodosa and trauma in one each. There were no procedure-related complications. No bowel 3 necrosis occurred because of embolisation. In 13 cases, the patients were discharged in good C59 Wnt cost condition (81%); the three patients with GVHD died because of the underlying disease.\n\nThe copolymer seems to have great potential in embolotherapy of acute arterial gastrointestinal bleeding. In our series none of the patients had rebleeding at the site of embolisation and no clinically obvious bowel necrosis occurred.”
“Thermophilic and mesophilic anaerobic digestion reactors (TR and MR) using food waste as substrate were compared
with emphasis on microbial responses to increasing organic loading rate (OLR). At OLR ranging from 1.0 to 2.5 g VS L-1 d(-1), MR exhibited more stable performance compared to TR in terms of Napabucasin methane yield. Amplicons pyrosequencing results revealed the distinct microbial dynamics in the two reactors. Primarily, MR had greater richness and evenness of bacteria species. With OLR elevated, larger shifts of bacterial phylogeny were observed in MR; Methanosaeta dominated in archaeal community in MR while Methanothermobacter and Methanoculleus were favored in TR. The high functional redundancy in bacterial community integrated with acetoclastic methanogenesis in MR resulted in its better performance; whereas delicate interactions between hydrogen-producer and hydrogenotrophic methanogens in TR were much more prone to disruption. These results are conductive to understanding the microbial mechanisms of low methane yield during food waste anaerobic digestion. (C) 2013 Elsevier Ltd. All rights reserved.”
“The monometallic (1-3) and heterobimetallic (4-6) complexes, containing 1,10-phenanthroline and indole-3-acetic acid were synthesized and characterized by spectroscopic (IR, UV-vis, NMR, ESI-MS) and analytical methods.
We also examined the pH data recorded on days 1 and 2 for significant day-to-day variability during 2 days of pH monitoring.\n\nResults: Two hundred eighty-nine BRAVO pH probes were placed from January 1, 2006 to December 31, 2008. At least I day of data was obtained in 278 patients (96.2%). Two days of data were obtained in 274 patients (94.8%). Of all of the reported complications, 1% occurred before deployment of the capsule, 4% occurred during deployment of the capsule, and 9% occurred after successful deployment of the capsule. One patient experienced a superficial esophageal tear that was 123 associated with failure of the capsule to release from the delivery
system. No patient requested removal of the capsule and all of the capsules detached within 14 days. In 9.12% of our SB202190 price patients, reflux index was normal on www.selleckchem.com/products/AG-014699.html day I and abnormal on day 2. There was no statistically significant difference between reflux index recorded on day 1 versus day 2 (P = 0.686).\n\nConclusions: The BRAVO pH capsule is easy to place, safe, and well tolerated by children. Performing a 48-hour study detected abnormal reflux in an additional 9% of our patients.”
“Systemic light chain amyloidosis (AL) is one of several protein misfolding diseases and is characterized by extracellular deposition of immunoglobulin
light chains in the form of amyloid fibrils . Immunoglobulin (Ig) proteins consist of two light chains (LCs) and two heavy Omipalisib concentration chains (HCs) that ordinarily form a heterotetramer which is secreted by a plasma cell. In AL, however, a monoclonal plasma cell population produces an abundance of a pathogenic LC protein. In this case, not all of the LCs pair with the HCs,
and free LCs are secreted into circulation. The LC-HC dimer is very stable, and losing this interaction may result in an unstable LC protein . Additionally, somatic mutations are thought to cause amyloidogenic proteins to be less stable compared to non-amyloidogenic proteins [3-5], leading to protein misfolding and amyloid fibril formation. The amyloid fibrils cause tissue damage and cell death, leading to patient death within 12-18 months if left untreated . Current therapies are harsh and not curative, including chemotherapy and autologous stem cell transplants. Studies of protein pathogenesis and fibril formation mechanisms may lead to better therapies with an improved outlook for patient survival.\n\nMuch has been done to determine the molecular factors that make a particular LC protein amyloidogenic and to elucidate the mechanism of amyloid fibril formation. Anthony Fink’s work, particularly with discerning the role of intermediates in the fibril formation pathway, has made a remarkable impact in the field of amyloidosis research.
In this group, six patients had >= 20% drop in rSO(2), and >= 50% drop in FVm. However, two patients had a non-significant drop in both rSO(2) and FVm (false negative). In the non-shunted group (41/49), one patient had a significant drop in rSO(2) (false
positive) while 10/41 patients had a >50% drop in FVm. This represents sensitivity of 75%, and specificity of 97.5% for CO compared to sensitivity of 75% and specificity of 75% for TCD in prediction of shunting. The positive predictive value and negative predictive value were 85.7 and 95.2%, respectively for CO, compared to 37.5 and 93.9% for TCD. Conclusions: TCD is less accurate than CO in predicting the need for carotid 123 shunting during CEA. A combination of both methods does not add to the accuracy of detecting the need for carotid AZD1480 shunting. (C) 2011 Published by European Association for Cardio-Thoracic Surgery.

“The delivery of site-specific post-translational modifications to histones generates an epigenetic regulatory network that directs fundamental DNA-mediated processes and governs key stages in development. Methylation
of histone H4 lysine-20 has been implicated in DNA repair, transcriptional c-Myc inhibitor silencing, genomic stability and regulation of replication. We present the structure of the histone H4K20 methyltransferase Suv4-20h2 in complex with its histone H4 peptide substrate and S-adenosyl methionine cofactor. Analysis of the structure reveals that the Suv4-20h2 active site diverges from the canonical SET domain configuration and generates
a high degree of both substrate and product specificity. Together with supporting biochemical data comparing Suv4-20h1 and Suv4-20h2, we demonstrate that the Suv4-20 family enzymes take a previously mono-methylated H4K20 substrate and generate an exclusively di-methylated product. We therefore predict that other enzymes are responsible for the tri-methylation of histone H4K20 that marks silenced heterochromatin.”
“Objective: Visuospatial working memory impairments have been implicated in the pathophysiology of URMC-099 manufacturer attention-deficit/hyperactivity disorder (ADHD). However, most ADHD research has focused on the neural correlates of nonspatial mnemonic processes. This study examined brain activation and functional connectivity for visuospatial working memory in youth with and without ADHD. Method: Twenty-four youth with ADHD and 21 age- and sex-matched healthy controls were scanned with functional magnetic resonance imaging while performing an N-back test of working memory for spatial position. Block-design analyses contrasted activation and functional connectivity separately for high (2-back) and low (1-back) working memory load conditions versus the control condition (0-back). The effect of working memory load was modeled with linear contrasts.
22.29 +/- 2.21 mm, p smaller than 0.001), which represented an 4 absolute and percent decrease in stent dimension of 1.10 +/- 0.40 mm and 4.70 +/- 1.76%, respectively. In the multivariate analysis, the predictors of larger recoil
were a higher prosthesis/annulus ratio (r(2)=0.0624, p=0.015) and the SAPIEN XT prosthesis (r(2)=0.1276, p=0.001). No significant changes in haemodynamic performance were observed at discharge and follow-up in patients with larger recoil. Conclusions: TAVI with a balloon-expandable valve was systematically associated with a certain degree of valve stent recoil after balloon deflation. Selleck DAPT A higher degree of valve oversizing and the SAPIEN XT prosthesis predicted a larger degree of stent recoil.”
“A novel phosphorylation see more motif for casein kinase 1 (CK1) in response to two sulfated lipids [sulfatide and cholesterol-3-sulfate (SCS)] was determined, using three functional proteins [myelin basic protein (MBP), tau protein (TP) and RhoA (a small GTPase)] and five
synthetic NIBP peptides as phosphate acceptors for the kinase in vitro. It was found that (i) MBP, p8 (positions 38-118) cleaved from MBP, and a synthetic peptide M103 were effectively phosphorylated, by CK1 delta in the presence of SCS; (ii) sulfatide in comparison with CH-3S highly enhanced autophosphorylation of CK1 delta; (iii) SCS had a high binding affinity with NIBP and peptide M103, but not other MBP peptides lacking K-G-R; and (iv) a novel consensus phosphorylation motif (K/R-X-K/R-X-X-S/T)
for CK1 was identified among several SCS-binding proteins (SCS-BPs) and three CK1 isoforms (delta, selleck kinase inhibitor epsilon and gamma). The binding of SCS to two basic brain proteins (MBP and TP) resulted in the high stimulation of their phosphorylation by three CK1 isoforms (c 6 and 6), but not CK1 gamma. In contrast, an acidic protein (RhoA) was effectively phosphorylated by CK1 delta in the presence of SCS, and also highly phosphorylated by CK1 gamma in the presence of sulfatide. Our results presented here suggest that (i) sulfatide may function as an effective stimulator for autophosphorylation of CK1; and (ii) cellular SCS-binding proteins, containing novel phosphorylation motifs for CK1, may be preferentially phosphorylated by CK1 with isoform specificity at the highly accumulated level of SCS in the brain.”
“Objectives: To determine the patterns and proximity of reflux events in patients with adult-onset asthma (AOA) using hypopharyngeal multichannel intraluminal impedance (HMII) and to assess outcomes of antireflux surgery (ARS) in patients with AOA.\n\nDesign: Retrospective review of prospectively collected data.\n\nSetting: University hospital.\n\nPatients, Interventions, and Outcomes: All patients with AOA referred to our testing center underwent HMII, and those with abnormal proximal exposure, defined as laryngopharyngeal reflux at least once a day and/or high esophageal reflux at least 5 times a day, subsequently underwent ARS.
ON cone bipolar cell axonal ribbons drive bistratified ONOFF ganglion cells in the OFF layer and provide ON drive to polarity-appropriate targets such as bistratified diving ganglion cells (bsdGCs). The targeting precision of find more ON cone bipolar cell axonal synapses shows that this drive incidence is necessarily
a joint distribution of cone bipolar cell axonal frequency and target cell trajectories through a given volume of the OFF layer. Such joint distribution sampling is likely common when targets are sparser than sources and when sources are coupled, as are ON cone bipolar cells. J. Comp. Neurol. 521:9771000, 2013.

“Background: Because breast cancer is a major public health issue, it is particularly important to measure the quality of the care provided to patients. Survival SB203580 rates are affected by the timeliness of care, and waiting times constitute key quality criteria. The aim of this study was to develop
and validate a set of quality indicators (QIs) relative to the timeliness and organisation of care in new patients with infiltrating, non-inflammatory and metastasis-free breast cancer undergoing surgery. The ultimate aim was to use these QIs to compare hospitals.\n\nMethods: The method of QI construction and testing was developed by COMPAQ-HPST. We first derived a set of 8 QIs from consensus guidelines with the aid of experts and professional associations and then tested their metrological properties in a panel of 60 volunteer hospitals. We assessed feasibility using a grid exploring 5 dimensions, discriminatory power using the Gini coefficient as a measure of dispersion, and inter-observer reliability using the Kappa coefficient.\n\nResults: Overall, 3728 records were included in the analyses. All 8 QIs showed acceptable feasibility (but one QI was subject to misinterpretation), fairly strong agreement between observers (Kappa = 0.66), and wide variations in implementation among hospitals (Gini coefficient < 0.45 except for QI 6 (patient information)). They are thus suitable
for use to compare hospitals and measure quality improvement.\n\nConclusions: Of the 8 QIs, 3 are ready for nationwide implementation (time Rabusertib to surgery, time to postoperative multidisciplinary team meeting (MDTM), conformity of MDTM). Four are suitable for use only in hospitals offering surgery with on-site postoperative treatment (waiting time to first appointment after surgery, patient information, time to first postoperative treatment, and traceability of information relating to prognosis). Currently, in the French healthcare system, a patient receives cancer care from different institutions whose databases cannot as yet be easily merged. Nationwide implementation of QIs covering the entire care pathway will thus be a challenge.”
“Synchronous bronchial carcinoid tumor and giant bullae are rare entities. In this article, we report a 62-year-old male presenting with dyspnea, cough and chest pain.
It has recently been reported that stent-graft coverage of the celiac artery (CA) during TEVAR is associated with a low risk of acute mesenteric ischemia. However, the long-term effect of CA coverage on foregut perfusion is unknown. Here, we report the case of a patient who underwent TEVAR with partial coverage of the CA and subsequently developed symptoms of chronic mesenteric ischemia (CMI). She was successfully treated with CA stent placement. Methods: Preoperative imaging included
computed tomography (CT) angiography of the abdomen and conventional aortogram of a redo-TEVAR, revealing near complete coverage of the CA orifice. Endovascular repair was done using a 7 mm x 20 mm biliary balloon-expandable stent (Cook #432 randurls[1|1|,|CHEM1|]# Medical Inc, Bloomington, Selleckchem HSP990 IN). A review of the current literature for this rare problem was performed. Results: Completion arteriography demonstrated successful revascularization of the CA without evidence of endoleak. Postoperatively, the abdominal pain was alleviated with early improved diet tolerance and weight gain. Follow-up CT at 6 month demonstrated widely patent CA. A PubMed review showed no reported cases of CMI secondary to CA coverage during TEVAR in the literature. Conclusions: CMI may develop with coverage of the CA during TEVAR. When other causes of abdominal pain and weight loss have been ruled out, revascularization of the CA can help alleviate the symptoms.”
radiofrequency (RF) signals may produce disorientation and nausea. In experiment I, we assessed mobile phone effects on graviception in nine symptomatic subjects after mobile telephone use and 21 controls. The mobile handset was strapped buy Volasertib to each ear for 30min in pulsed emission, continuous RF emission, or no emission test mode, respectively. The subjective visual vertical and horizontal (SVV/SVH) were tested from min 25 of exposure. There was no exposure effect; however, there was an ear effect, with
the SVV/SVH being shifted to the opposite direction of the ear exposed. This could be due to thermal or RF effects or handset weight. In experiment II, we assessed the handset weight effect on 18 normal controls. After baseline SVV/SVH, the switched off handset was strapped to either ear; the SVV/SVH was repeated 25min later. A significant ear effect was found. We compared the observed ear effect SVV/SVH change in the experiment II group to the continuous exposure ear effect change in the experiment I group, and the difference was not significant. The ear effect was attributed to a minor head tilt due to the handset weight, or proprioceptive stimulation of neck muscle affecting the perception of verticality.

“Background: The impact of adherence to clinical practice guidelines (CPGs) for loco-regional treatment (i.e. surgery and radiotherapy) and chemotherapy on local disease control and survival in sarcoma patients was investigated in a European study conducted
in an Italian region (Veneto).\n\nPatients and methods: The completeness of the adherence to the Italian CPGs for sarcomas treatment was assessed by comparing the patient’s charts and the CPGs. Propensity score-adjusted multivariate survival analysis was used to assess the impact of CPGs adherence on patient clinical outcomes.\n\nResults: A total of LY294002 in vivo 151 patients were included. Adherence to CPGs for loco-regional therapy and chemotherapy was observed in 106 out of 147 (70.2%) and 129
out of 139 (85.4%) patients, respectively. Non-adherence to CPGs for loco-regional treatment was independently associated with AJCC stage III disease [odds ratio (OR) 1.77, P = 0.0111 and tumor-positive excision margin (OR 3.55, P = 0.003). Patients not treated according to the Nepicastat clinical trial CPGs were at a higher risk of local recurrence [hazard ratio (HR) 5.4, P <0.001] and had a shorter sarcoma-specific survival (HR 4.05, P< 0.001), independently of tumor stage.\n\nConclusions: Incomplete adherence to CPGs for loco-regional treatment of sarcomas was associated with worse prognosis in patients with non-metastatic tumors.”
“Background: It was still unclear whether the methodological reporting quality of randomized controlled trials (RCTs) in major hepato-gastroenterology journals improved after the Consolidated Standards of Reporting Trials (CONSORT) Statement was revised in 2001.\n\nMethods: RCTs in five major hepato-gastroenterology journals published in 1998 or 2008 were retrieved from MEDLINE using a high sensitivity search method and their reporting quality of methodological details were evaluated based on the CONSORT Statement and Cochrane Handbook for Systematic Reviews of interventions. Changes of the methodological reporting quality between 2008 and 1998 were calculated by risk ratios with 95% confidence intervals.\n\nResults: A total
of 107 RCTs published Dactolisib inhibitor in 2008 and 99 RCTs published in 1998 were found. Compared to those in 1998, the proportion of RCTs that reported sequence generation (RR, 5.70; 95% CI 3.11-10.42), allocation concealment (RR, 4.08; 95% CI 2.25-7.39), sample size calculation (RR, 3.83; 95% CI 2.10-6.98), incomplete outecome data addressed (RR, 1.81; 95% CI, 1.03-3.17), intention-to-treat analyses (RR, 3.04; 95% CI 1.72-5.39) increased in 2008. Blinding and intent-to-treat analysis were reported better in multi-center trials than in 4 single-center trials. The reporting of allocation concealment and blinding were better in industry-sponsored trials than in public-funded trials. Compared with historical studies, the methodological reporting quality improved with time.
Recently we reported a nitrobenzenethiol (NBT) based method for screening thiol reactive skin sensitizers, however, amine selective sensitizers are not detected by this assay. In the present study we describe an amine (pyridoxylamine (PDA)) based kinetic assay to complement the NBT assay for identification of amine-selective and non-selective skin sensitizers. UV-Vis spectrophotometry and fluorescence were used to measure PDA reactivity for 57 chemicals including anhydrides, 3 aldehydes, and quinones where reaction rates ranged from 116 to 6.2 x 10(-6) M-1 s(-1) for
extreme to weak sensitizers, respectively. No reactivity towards PDA was observed with the thiol-selective sensitizers, non-sensitizers and prohaptens. The PDA rate constants correlated significantly with their respective murine local lymph node assay (LLNA) threshold EC3 values (R-2 = 0.76). The use of PDA serves as a simple, inexpensive amine based method that shows promise as a preliminary click here screening tool for electrophilic, amine-selective skin sensitizers.

“Saponifiable lipids (SLs) were extracted with hexane from wet biomass (86 wt% water) of the microalga Nannochloropsis gaditana in order to transform them selleck screening library into fatty acid methyl esters (FAMEs, biodiesel). The influence
of homogenization pressure on SL extraction yield at low temperature (20-22 degrees C) was studied. Homogenization at 1700 bar tripled the SL extraction yield. Two biomass batches with similar total lipid content but different lipidic compositions were used. Batch 1 contained fewer SLs (12.0 wt%) and neutral saponifiable lipids (NSLs, 7.9 wt%) than batch 2 (21.6 and 17.2 wt%, respectively). For this reason, and due to the selectivity of hexane toward NSLs, high SL yield (69.1 wt%) and purity (71.0 wt%) were obtained from batch 2. Moreover, this extract contains a small percentage HSP990 chemical structure of polyunsaturated fatty acids (16.9 wt%), thereby improving the biodiesel quality. Finally, up to 97.0% of extracted SLs were transformed to FAMEs by acid catalyzed transesterification. (C) 2014 Elsevier Ltd. All rights reserved.”
(PTN) and midkine (MK) are two growth factors highly redundant in function that exhibit neurotrophic actions and are upregulated at sites of nerve injury, both properties being compatible with a potential involvement in the pathophysiological events that follow nerve damage (i.e. neuropathic pain). We have tested this hypothesis by comparatively studying PTN and MK gene expression in the spinal cord and dorsal root ganglia (DRG) of three rat strains known to differ in their behavioural responses to chronic constriction injury (CCI) of the sciatic nerve: Lewis, Fischer 344 (F344) and Sprague-Dawley (SD). Real time RT-PCR revealed minimal changes in PTN/MK gene expression in the spinal cord after CCI despite the strain considered, but marked changes were detected in DRG.
A “postoperative” computed tomography (CT) scan was performed on cadavers where instrumentation was done using the C-ARM. An independent musculoskeletal radiologist assessed final images for screw position. Time 123 required to set up and instrumentation was recorded. Dosimeters were placed on multiple aspects of cadavers and surgeons to record radiation exposure.\n\nResults. There were no differences in breach
rate between the O-ARM and C-ARM groups (5 vs. 7,. 2 = 0.63, P = 0.4). The setup time for the O-ARM group was longer than that for CYT387 mw the C-ARM group (592 vs. 297 s, P < 0.05). However, the average total time was statistically the same (1629 vs. 1639 s, P = 0.96). Radiation exposure was higher for surgeons in the C-ARM group and cadavers in the O-ARM group. When a “postoperative” CT scan was included in the estimation of the total
radiation exposure, there was less of difference between the groups, but still more for the O-ARM group.\n\nConclusion. In cadavers without deformity, O-ARM use results in similar breach rates as C-ARM for the placement of pedicle screws. Time for instrumentation is shorter with the O-ARM, but requires a longer setup time. The O-ARM exposes less radiation to the surgeon, but higher doses to the cadaver.”
“Combined Copanlisib distal venous bypass grafting and free flap transfer can achieve successful treatment of soft tissue defects due to advanced leg ischemia. However, this combined approach is a complex technique involving multiple anastomoses on the same arterial axis with an increased risk of thrombosis. To reduce this risk, we have proposed a new bypass-flap (BF) reconstruction technique using an arterial graft and a free flap supplied by a collateral branch of the graft. The purpose of this report is to document the outcome in the first 10 patients treated using the BF reconstruction technique. From 2002 to 2004, a total of 10 patients with a mean age of 67 years (range 55-78) were treated using a BF. All patients presented critical ischemia with
soft tissue defects resulting in exposure of tendons and muscles on the foot or ankle. PARP inhibitor Distal anastomosis was made between the distal branch of the BF and the pedal artery in five cases, the posterior tibial artery or plantar artery in four cases, and the peroneal artery in one case. In six cases proximal anastomosis was performed between the leg artery and arterial autograft. In the remaining four cases proximal anastomosis required extension of the bypass using a venous graft. The mean duration of hospitalization was 25 days. During the postoperative period, one patient died due to stercoral peritonitis and one patient required major amputation due to unrelenting sepsis. Bypass occlusion was not observed. Mean follow-up was 24 months ( range 14-36).
