e., absolute value) or maximum (i.e., relative) decrease of CA 19-9. In the total sample (N=319), the median time to progression (TTP) was 4.3 and 3.9 months in patients randomly assigned to GemCap or Gem, respectively (Herrmann et al, 2007); that selleck products is, the majority of patients failed during our observation period of 6 months. In a Cox model with stratification factors, treatment arm and baseline CA 19-9 >1 �� ULN (N=247; TTP GemCap and Gem: 4.4 and 3.9 months), the strongest effect was present for CA 19-9, followed by physician-rated KPS and pain requiring analgesic medication, as shown in Table 3. After adding the QOL indicators separately, tiredness (good vs intermediate) was additionally prognostic, with less tiredness resulting in a better survival (HR: 0.68, 95% CI: 0.48-0.96, P<0.05).

Similarly, patients who reported less pain (good vs intermediate) had a better survival (HR: 0.69, 95% CI: 0.48�C0.98, P<0.05). It is important to note that these effects were not linear but discriminated patients with low symptom burden from the others. The remaining indicators were not associated with survival. Pain and tiredness (borderline effect) were also the only prognostic indicators in the model without clinical factors (Table 3). Table 3 Prognostic value of baseline factors for overall survival in patients with an increased tumour marker concentration Finally, a Cox model was calculated including both the clinical factors and QOL indicators (Table 3). Patient-rated pain intensity was more prognostic than pain requiring analgesic medication according to the treating physician.

In contrast, patient-rated functional performance remained unprognostic after exclusion of KPS. Survival according to tiredness and pain intensity is shown in Figure 1. A univariate analysis of all available patients (including CA 19-9 1 �� ULN) showed similar findings. Figure 1 Overall survival by baseline scores of tiredness (cut-off points: 50, 77) and pain (cut-off points: 71, 92). Both indicators have a range from 0 to 100, with higher scores indicating a better condition. P-values are based on log-rank test. Associations between CA 19-9 and QOL during chemotherapy Mean changes in physical QOL domains across the whole observation period were marginally correlated with the maximum CA 19-9 decrease, ranging from R=0.15 (P<0.05) for functional performance to R=0.28 (P<0.

001) for physical well-being. To investigate the role of CA 19-9 in estimating palliation, we first explored the prognostic GSK-3 value of CA 19-9 baseline concentration and of maximal decrease for QOL during chemotherapy by mixed-effects models using all available data until failure (N=231). The only, but not relevant, difference by baseline CA 19-9 was present in pain: Patients with baseline CA 19-9 below the median indicated marginally less pain on treatment (average score: 8.5 vs 8.3 P<0.05).

05; Fig. 1D), worsened in one patient (7%), and remained stable in seven patients (40%). The improvement in inflammation and piecemeal activity after treatment with losartan was significant http://www.selleckchem.com/products/Imatinib-Mesylate.html (P < 0.05 for both; Table 4). In contrast, lobular inflammation did not change in nine patients (65%, not significant; Table 4), improved in three patients (21%), and worsened in two patients (14%). Patients with improvement in liver fibrosis or inflammation were not different regarding age, gender, body mass index, duration of infection, baseline serum viral load, baseline liver tests, degree of activation of the systemic RAS at baseline, or treatment compliance. Moreover, the degree of activation of the systemic RAS following treatment with losartan was not different between responder and nonresponder patients.

Changes in hepatic gene expression of fibrosis-related genes after treatment with oral losartan. We first analyzed hepatic gene expression in patients with CHC compared with normal livers (n = 6). Most candidate genes were differentially expressed in livers with CHC compared with control livers. Gene expression of extracellular proteins (��1 chains of procollagen type I and type IV), major fibrogenic (TGF-��1, ACE-1 and 2) and proinflammatory mediators (TNF-��) as well as regulators of matrix degradation (MMP-2, TIMP-1, and ut-PA) were upregulated in livers of patients with chronic HCV infection. In contrast, genes mainly expressed by hepatocytes (i.e., cytochrome P-450 2E1) and AT1 receptors were downregulated in CHC livers compared with normal livers.

These findings are in agreement with previous reports on hepatic gene expression in patients with CHC (2, 36). Components of the NOX complex (NOX-4, Rac-1, and Rac-2) were upregulated in livers with chronic HCV infection. We performed an unsupervised hierarchical clustering of normal livers and patients with chronic HCV infection according to the expression profile of the selected genes. On the basis of similarity in gene expression profiles, this procedure adequately clustered livers from patients with CHC and normal livers in two different groups (Fig. 2). Fig. 2. Unsupervised hierarchical clustering of normal (NORM) livers (n = 6) and patients with chronic hepatitis C (HCV) before treatment with oral losartan (n = 14) according to the expression profile of the selected genes.

Following treatment with losartan for 18 mo, there was a significant reduction in the expression of nine Anacetrapib genes (Table 5). Importantly, four of these genes are known to be involved in liver fibrogenesis and were upregulated at baseline compared with normal livers. Expression of procollagen ��1(I) and ��1(IV), two major extracellular proteins in the fibrotic liver, decreased in the majority of patients after AT1 receptor blockade. Procollagen ��1(I) decreased in 11 patients with a mean reduction of ?31% (P < 0.05 vs. baseline).

StemPro human ADSCs (Life Technologies) have the same phenotypic

StemPro human ADSCs (Life Technologies) have the same phenotypic and functional characteristics as bone marrow-derived mesenchymal stem cells. ADSCs were maintained in MesenPRO RS basal medium plus Growth Supplement. HPAd were cultured in preadipocyte growth medium, Dorsomorphin side effects whereas HAd were maintained in adipocyte differentiation medium according to the manufacturer��s instructions (Cell Application, Inc.). Adipogenic differentiation was induced in Poietics bone marrow-derived hMSCs (Lonza) according to the manufacturer��s instructions. The PLS-derived cell line LS226 was maintained in RPMI plus GlutaMAX (Life Technologies), 1�� MEM Essential Vitamin Mix (BioWhittaker), 1�� ITES (BioWhittaker), 1�� penicillin/streptomycin/L-glutamine (Life Technologies), 1 mM sodium pyruvate (CellGro), 1�� nonessential amino acids (NEAA) (Lonza), and 20% fetal bovine serum (Life Technologies).

Measurement of triglyceride (TG) content Following each cycle of induction, hMSCs that had been seeded in duplicate in a 24-well plate and cultured until confluence were rinsed with 1�� phosphate buffered saline (PBS) and then incubated with 30 ��L of AdipoRed (Lonza) in 1 mL of 1�� PBS for 10 minutes. TG content was determined by AdipoRed fluorescence at 538 nm. Baseline/background was established by measuring fluorescence in the LS2 cell line, which was subtracted from the induced cells�� signal for each week. Immunofluorescence of CDO1 Following each cycle of induction, hMSCs grown in duplicate in four-well chamber slides were stained for CDO1. Cells were washed with 1�� PBS and fixed with freshly prepared 3.

7% formaldehyde/1�� PBS for 10 minutes before permeabilization with 10% NP40/1�� PBS for 10 minutes. Following blocking of epitopes with PBG (0.2% w/v cold water fish gelatin (Sigma)/0.5% w/v bovine serum albumin (BSA) (Sigma)/1�� PBS), cells were incubated with a 1:500 dilution of anti-CDO1 antibody (Sigma-Aldrich) overnight at 4��C. CDO1 was detected using a DyLight 549 conjugated donkey anti-rabbit secondary antibody at a 1:500 dilution (Jackson ImmunoResearch). Nuclei were counterstained with 4��,6-diamidino-2-phenylindole (DAPI; Sigma). Specimens were mounted with ProLong Gold antifade reagent (Life Technologies) and examined using a Nikon A1 scanning confocal microscope. Quantitation of CDO1 mRNA expression Total RNA from tumor specimens and cell lines was extracted using QIAzol (Qiagen) and TRIzol (Life Technologies), respectively.

RNA was purified using the RNeasy kit (Qiagen) and quantified on a NanoDrop Entinostat ND-1000 spectrophotometer. Expression was measured by at least one of two methods: quantitative real time-PCR (qRT-PCR) or gene expression array. For qRT-PCR, cDNA was made from 100 ng RNA using the High Capacity cDNA Reverse Transcriptase kit according to the manufacturer��s instructions (Life Technologies). CDO1 mRNA expression was quantified by qRT-PCR using TaqMan assay Hs00156447_m1.

These findings confirm the possibility selleck 17-AAG to increase the biosafety of gene therapy using lentiviral vectors for the treatment of liver-based inborn errors of metabolism, which remains a prerequisite before clinical application. Materials and Methods Animals. Nonhuman primates were male captive-bred Macaca fascicularis (n = 3), aged between 2 and 3 years, weighing 2.5 �� 0.5 kg, and purchased from Bioprim (Bazi��ge, France). Experiments were performed in the animal facilities of the ��Centre of Boisbonne�� (Nantes, France). Animals were maintained on a standard diet and kept in 12-hour light-dark cycles. All animal studies were performed according to institutional guidelines set forth by the Swiss National Animal Care Committee and by the French Institutional Animal Care and Use Committee of the University of Nantes.

Surgical procedures. Induction and maintenance of anesthesia were achieved with isoflurane in a mixture of 50% O2 in air. Following tracheal intubation, remifentanil was infused continuously in order to ensure adequate analgesia throughout the surgical procedure. After a median laparotomy, a left lobectomy was performed. Hepatocytes were isolated from the resected left lateral lobe (weighed about 8 g) and rapidly transduced in suspension (see below). Transduced hepatocytes (1�C2 �� 108) were infused back to the macaques via a branch of the mesenteric vein at a rate of 2 ml/minute using a 25G catheter. No thrombosis of the portal venous system was observed. Animals were maintained under general anesthesia during the whole time of the ex vivo cell manipulation.

Postoperative analgesia (buprenorphine) was provided, and alimentation was reintroduced in the evening on the same day. For viral vector dissemination analysis, multiple surgical biopsies (testis, epididymis, deferent duct, muscle, intestine, lymph nodes, greater omentum, and bone marrow) were performed under general anesthesia 8 and 15 months after transplantation. At the end of the follow-up period, valganciclovir (Valcyte; Roche, Basel, Switzerland) (GCV) was administered orally for 1 week (50 mg/kg once a day). One month after GCV treatment, animals were euthanized and the same multiple biopsies were done as well as kidney, pulmonary, cardiac, and brain biopsies. Hepatocyte isolation and cell culture.

HeLa and 293T cells were maintained in Dulbecco’s modified Eagle’s medium containing 10% fetal bovine serum, 10 mmol/l 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid, 2 Dacomitinib mmol/l glutamine, and antibiotics (Invitrogen, Carlsbad, CA). Primary hepatocytes were isolated from the left liver lobe of the macaques by a three-step collagenase perfusion as previously described.38 The liver capsule was then disrupted and cells were dispersed in cold Dulbecco’s modified Eagle’s medium/F12 medium (Invitrogen) without serum or antibiotics.

IGF-1R antagonists inhibit proliferation of ACC cell lines IGF

.. IGF-1R antagonists inhibit proliferation of ACC cell lines IGF signaling regulates several aspects of cellular function including the enhancement of proliferation. To test the functional consequence of IGF-1R inhibition, MTS proliferation assays were performed on H295 cells treated with ARQ197 IMC-A12 or NVP-AEW541 (Fig. 44).). We used the RL251 cell line as a negative control in these assays because it lacks expression of IGF-1R protein in comparison with other ACC lines. As predicted, increasing doses of IMC-A12 had no substantial effect on the RL251 cells, whereas high concentrations of the antibody exhibited antiproliferative effects on H295 cells (Fig. 44,, left panel). The IMC-A12 IC50 value for the H295 cells was 90 nm, but 50% inhibition was not achieved with RL251 cells, even at the highest IMC-A12 dose (P < 0.

001 comparing RL251 vs. H295 at 100 nm A12). The NVP-AEW541 IC50 value for H295 cells was 2.7 ��m, whereas for RL251 cells, the IC50 was 36 ��m (P < 0.001 comparing RL251 vs. H295 at 3 ��m NVP-AEW541), again demonstrating targeted suppression of the H295 cell line��s ability to proliferate due to the presence of IGF-1R. Figure 4 Antiproliferative effects of IGF-1R antagonist treatments in vitro. H295 and RL251 cells were incubated with increasing micromolar concentrations of NVP-AEW541 (right panel) or nanomolar concentrations of IMC-A12 (left panel), and proliferation was assessed ... Targeting of IGF-1R delays tumor xenograft growth Stemming from our data revealing IGF-1R inhibition results in a significant decrease of downstream signaling and proliferation in vitro, we assessed its in vivo activity using human ACC cell lines.

Using the rationale discussed above, we used the RL251 cell line as an additional control in these assays. H295 or RL251 cells were inoculated sc into athymic nude mice, and the mice were subsequently randomized into three treatment groups (n = 8 tumors per group for H295 and n = 10 for RL251): placebo, IMC-A12 treatment, and NVP-AEW541 treatment. Tumor volume measurements were taken three times a week for 21 d. The data were plotted as the log ratios of tumor size over initial tumor size to more accurately reflect the percent reduction in tumor size and, at the same time, account for the variable initial tumor sizes in each mouse (Fig. 5A5A).). RL251 xenografts had a higher tumor engraftment rate than H295 xenografts (94 vs.

75%, data not shown). IMC-A12 was well tolerated in treated mice with no substantial adverse Dacomitinib effects or weight changes observed between groups (data not shown). The treatment of H295 tumors with IMC-A12 over a 21-d span (Fig. 5A5A,, left panel) resulted in a significant reduction in tumor size over untreated controls (P < 0.001 from day 7 onwards). Treatment in RL251 xenografts (Fig. 5A5A,, right panel) resulted in a statistically insignificant reduction in tumor volume at each time point, underscoring the specificity of IMC-A12.

As shown in Figure 1A, after in vitro culture for 6�C12 days under sphere-forming conditions, HT29/CD44+ and HT29/CD44?/CD44-myc molarity calculator cells produced sphere colonies, whereas HT29/CD44?/Mock cells did not. Furthermore, CD44 transcripts eliminated in HT29/CD44+ cells by a lentivirus-based RNA interference technique (Lee et al, 2008) significantly inhibited sphere formation. To test the self-renewal capability of the sphere-forming cells, we dissociated the primary spheres into single cells and performed secondary sphere assays. Interestingly, we found ~10 secondary spheres in HT29/CD44+ and HT29/CD44?/CD44-myc cells formed per 100 seeded cells (10%) but <3% formed in HT29/CD44?/Mock and HT29/CD44+/CD44-shRNA cells. Moreover, the proportion of sphere-forming cells isolated from already-formed spheres remained the same through subsequent serial passages (Figure 1B).

This indicates that the sphere-forming cells are capable of self-renewing and that the conditions of sphere culture encourage an increase in and subsequent stable maintenance of the number of self-renewing cells among the larger population of CD44-expressing cells. Figure 1 CD44 allows outgrowth of cells into spheres, leading to stable changes in cell proliferative ability and morphology after the suspension culture. (A) Microscopic analysis of spheres cultivated in suspension for 6 and 12 days. (Top panel) HT29/CD44? … To further define the regions of CD44 that are involved in sphere formation, a series of C-terminal deletion mutants were generated from the wild-type and from the cysteine mutant.

Figure 1C shows that CD44s��67, CD44s��67C286A, CD44s��61C286,295A and CD44s��61C286,295A/KA failed to promote sphere formation. This is consistent with our previous observation that CD44 promotes matrix-derived survival through the CD44�CSrc�Cintegrin axis in lipid rafts (Lee et al, 2008). Wild-type CD44s, CD44sC286,295A, and CD44s��37C286,295A can translocate into lipid rafts, associate with Src, trigger integrin activation, and then provide survival signalling. Taken together, a one-to-one relationship may exist between sphere formation and CD44-elicited survival signalling. In contrast, the N terminus of CD44 did not contribute to sphere formation (Figure 1D). The spheres formed from CD44-expressing cells could be maintained in suspension for months. During this period, they formed a central cavity and increased in size.

When the spheres were transferred back to adhesive tissue culture plates, they migrated back onto plates, reforming a monolayer (Figure 1E). Surprisingly, all of the cells in these monolayers differed from Anacetrapib HT29 and DLD-1 before sphere formation��they were morphologically heterogeneous and smaller (compare SPH �� AD with AD). These monolayer cells derived from HT29/CD44+ (Figure 1E) and DLD-1/CD44+ (data not shown) spheres were smaller in size and generated a morphologically distinct cell type, demonstrating a stable morphological transition.

With the thoracolumbar fascia divided, the quadratus lumborum and

With the thoracolumbar fascia divided, the quadratus lumborum and psoas muscles become visible. Traversing neurovascular bundles supplying the abdominal wall may be seen and attempts should be made to preserve these, although division does not appear to cause adverse effects. Now digital blunt dissection facilitates http://www.selleckchem.com/products/azd9291.html easy separation of the peritoneum from the posterior abdominal wall musculature and allows identification of the anterolateral aspect of the vertebral bodies and intervertebral discs (Figure 4(b)). Figure 4(a) Division of thoracolumbar fascia at its attachment to the transverse processes allows entry into retroperitoneal space. Erector spinae muscle is retracted laterally. (b) With the thoracolumbar fascia divided the psoas muscle becomes visible. The peritoneum …

We do not routinely suture small breaches in the fragile peritoneum or attempt to visualise the aorta and inferior vena cava, which can be palpated medially. As suggested by Baramki et al. [17], a Hohmann retractor with the tip positioned on the contralateral vertebral body is the best instrument to retract the abdominal contents and great vessels. The psoas and quadratus lumborum muscles are easily retracted posterolaterally, by the assistant, using a Diva retractor, further exposing the intervertebral discs (Figure 4(c)). The intervertebral bodies appear a long concave depressions, whilst the intervening intervertebral discs are convex swellings, which are easily palpated. By positioning retractors immediately over the discs, disruption of lumbar segmental arteries and veins, which are located approximately 1cm caudal to the inferior endplate, can be avoided.

If bleeding from these segmental vessels occurs, bipolar cautery affords simple haemostasis. Surgical loupe magnification with headlight illumination facilitates identification and preservation of exiting vessels and nerves.At this stage, the exact disc level can be confirmed with lateral X-ray. Using the far-lateral approach described, the entire ipsilateral half of the intervertebral discs can be identified. Rotating the operating table away from the surgeon will open the view to the anterior portion of the disc. From our experience, muscular attachments over the disc can be easily swept aside using blunt dissection for levels L3/4 and above. For levels L4/5 and below, thicker tendinous muscular attachments require sharp division, using bipolar diathermy and scissors in order to expose the disc. Disc levels from T12/L1 to L5/6 can be easily reached using this lateral approach. The L6/S1 disc is difficult to access due to obstruction Cilengitide by the iliac crest.

Additionally, whereas increased expression of PLA is common in pe

Additionally, whereas increased expression of PLA is common in peripheral nerve after injury, the same is not evident after injury to the optic nerve, which correlates to slow WD in the central nervous system (CNS).AA itself has been found to posses trophic and Wortmannin IC50 toxic effects both in hippocampal neurons and in chick motoneurons in vitro, possibly trough a LOX pathway [16, 17]. AA can also participate in neurite growth trough a calcium-dependent mechanism [18].There is another potential mechanism by which PL and AA contribute to the pathophysiology of nerve degeneration. The oxidative metabolism of AA is known to result in the production of free radicals and in lipid peroxidation. These processes are partly responsible for the initial local damage induced by acute injury in nerve tissue, due to the rich lipid content of myelin sheats.

The full implication of this association remains to be elucidated.3. COX COXs catalyze the conversion of AA to PGs and thromboxanes, which trigger as autocrine and paracrine chemical messengers in many physiological and pathophysiological responses [19]. The COXs exist in two isoforms, a constitutive form (COX-1) and an inducible form (COX-2), and a COX-1 splice variant termed as COX-3 has been reported [20]. COX-1 and -2 share the same substrates, produce the same products, and catalyze the same reaction using identical catalytic mechanisms [21, 22]. The COX-1 enzyme is expressed in most tissues and is responsible for maintaining homeostasis (gastric and renal integrity) and normal production of PGs.

COX-2 is predominantly found in brain, kidney, and endothelial cells and is significantly upregulated as part of various acute and chronic inflammatory conditions. COX-2 expression can be induced in response to growth factors, cytokines, and proinflammatory stimuli. Moreover, COX-2 has been implicated in the regulation of the inflammatory response that occurs during WD, both directly and by way of their products, eicosanoids.After nerve injury, COX-2 expression is locally upregulated, but this phenomenon has been mainly linked to the pathogenesis of neuropathic pain [23, 24], although COX-1 could also participate in tissue remodeling during WD in the spinal cord [25]. Both COX-1 and COX-2 expression is increased in macrophages and SCs Cilengitide in animal models of inflammatory demyelinating diseases [7]. The administration of COX inhibitors obstruct myelin debris signals that negatively affect axonal regeneration after injury, resulting in increased axonal regeneration in vitro, and COX inhibitors can also affect SC and macrophage phagocytic activity [26, 27].

, shorter program/day TC) or with a control group out of treatment (e.g., in prison/waitlist selleck bio controls). Studies needed to report findings on TC outcomes separately from these of other types of interventions (e.g., aftercare). Available reviews and meta-analyses were not included, but all studies selected for the reviews were screened based on the aforementioned inclusion criteria. Studies that did not focus on TC treatment, but on another type of residential care, were excluded from the paper. If several publications concerned the same baseline sample and study design, these publications were regarded as one single study.2.1. Search StrategyWe searched the following databases: ISI Web of Knowledge (WoS), PubMed, and DrugScope, up to December 31, 2011. There were no language, country, or publication year restrictions.

Search strategies were developed for each database, based on the search strategy developed for ISI Web of Knowledge, but were revised accordingly to take into account differences in controlled vocabulary and syntax rules. The key words we searched for were ��therapeutic communit*�� AND ��drug* or addict* or dependen* or substance use�� AND ��outcome* or evaluation or follow-up or effectiveness.�� The reference lists of retrieved studies and of available reviews were checked for relevant studies. In addition, the index of the International Journal of Therapeutic Communities, a specialized peer-reviewed journal on therapeutic communities and other supportive organisations, was screened for relevant publications.

Our search strategy revealed 997 hits, which resulted in a first selection of 185 records, based on title and abstract (see Figure 1). Thorough analysis of these abstracts by two independent reviewers (Mieke Autrique and Wouter Vanderplasschen) led to the selection of 46 studies. Figure 1Flowchart of the search process and number of studies retained/excluded in each phase.In addition to the database search, conference abstracts of European Federation of Therapeutic Communities (EFTC), World Federation of Therapeutic Communities (WFTC), and European Working Group on Drugs Oriented Research (EWODOR) conferences and the grey literature were scanned for relevant (un)published studies. We made a search of the registry of ongoing clinical trials to identify any ongoing RCTs. In case a publication could Carfilzomib not be tracked through the Ghent University online library system, the study authors were contacted for a copy of the original manuscript. Finally, TC experts in various countries as well as the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) national focal points were contacted to retrieve additional (un)published or ongoing studies that have assessed the effectiveness of TCs for addictions.2.2.

The rapid growth of China’s industry highly depends on energy and

The rapid growth of China’s industry highly depends on energy and environment, and industry plays the FTY720 structure most important role in the energy saving and emission reduction of national economy. Therefore, it is significantly necessary to measure the costs of energy and environment. Since traditional distance function cannot estimate the harmful effects of environmental pollution, many studies use indirect methods to calculate TFP with the consideration of pollutant emissions, which is obviously too simplified. Some researchers use radical and oriented data envelopment analysis (DEA) to compute directional distance function in order to simulate the harmful effects of environmental pollution, but this method will overestimate the efficiency of the evaluation object [12].

In contrast, nonradical and nonoriented directional distance function which is slack-based measure (SBM) and Luenberger productivity index can overcome the above deficiencies in the measurement of environmental efficiency and environmental TFP [13, 14]. In addition, only one or several bad or undesirable outputs have been considered in the existing literature. However, for China’s industry at this stage, all energy inputs and pollutant emissions should be taken into account, by which environmental efficiency and environmental TFP can reflect the quality contribution to economic growth more precisely [15]. Therefore, on the basis of existing literature, this paper aims to use SBM directional distance function to measure environmental efficiency and its components of 36 subindustries of China’s industry, use SBM directional distance function and the Luenberger productivity index to measure the environmental TFP and its components, then test, and compare the differences of the determinants’ impacts.

2. Model Specification Different from the traditional production function, production technology considering energy and environment must reflect resource saving and environmental protection. Since resources can be introduced into productivity analysis framework as traditional inputs (such as capital and labor), the difficulty of constructing production frontier function is how to take environmental factors into account. In order to combine energy and environment factors with traditional economic factors (capital, labor, and output), according to F?re et al. [16], this paper considers every subindustry of China’s industry as a decision making unit (DMU) and construct the Brefeldin_A optimal production frontier of each period. It is assumed that there are N kinds of inputs x = (x1,��, xN) RN+ in every subindustry, M kinds of good outputs y = (y1,��, yM) RM+, and I kinds of bad or undesirable outputs b = (b1,��, bI) RI+.
