“Túmulo, túmulo, túmulo”, de Mário de Andrade e os jogos de identidades
Authors: Gebra Fernando De Moraes
Published: July 2017

Como intelectual preocupado com as questões sociais do seu tempo, Mário de Andrade (1893-1945) escreveu um conjunto de narrativas intitulado Os contos de Belazarte. Nesses contos, o autor não somente apresenta atitudes de experimentos com a linguagem, como também salienta uma postura ideológica ao enfatizar a descrição dos bairros operários de São Paulo e ao denunciar, por meio do discurso do narrador Belazarte, o imobilismo, o desenraizamento, a inercia e a apatia das personagens “sem letras nem cidade”. A escolha do conto “Túmulo, túmulo, túmulo” como corpus de análise permite um estudo das identidades das personagens Belazarte e Ellis, que se constroem na tensão entre o socialmente aceito e o conteúdo recalcado do desejo. Ao contrário dos outros contos, Belazarte mistura-se à matéria narrada, em jogos discursivos entre dizer e não dizer, saber e não saber, implícito e explícito. Dessa forma, o presente trabalho centra-se nas estratégias discursivas e nos efeitos de sentido gerados no conto, relativos ao desejo homoerótico reprimido.

Published: July 2017

Objetivo. Analizar los principales efectos que ejercen la migración y la influencia urbana sobre las formas de adquisición y consumo de los productos alimenticios en dos comunidades mayas de Yucatán. Metodología. Se basó en una encuesta por muestreo estadístico a jefas de familias. El procedimiento fue por conglomerados. Resultados. Se encontró que el porcentaje y motivos de la migración fueron diferentes; el tipo de alimento en la dieta y su forma de adquisición dependen de la disponibilidad, el acceso físico y de la economía de las familias. Además los sistemas de producción milpa y traspatio influyeron sobre la composición de la dieta habitual. Limitaciones. La principal limitación es la falta de capacidad de los sistemas agrícolas tradicionales para satisfacer las necesidades alimenticias, lo cual se profundiza por el abandono paulatino de la producción primaria. Conclusión. La migración, asociada a la influencia urbana, modificó la dinámica familiar y la producción de autoconsumo, aspectos que influyeron sobre la adquisición de los alimentos y diversidad de la dieta familiar.

Inspección autónoma de entornos submarinos
Authors: Hernández Vega Juan David , Carreras Marc
Published: July 2017

Este trabajo presenta una estrategia para la inspección de entornos marinos mediante el uso de vehículos submarinos autónomos (Autonomous Underwater Vehicle, AUV). Los entornos a explorar se asumen como desconocidos, lo que requiere que el vehículo tenga la capacidad de mapear y planificar caminos libres de colisión simultáneamente y en línea. Para esto, presentamos un sistema compuesto por tres bloques funcionales de mapeo, planificación y coordinación. El primero de ellos utiliza una estructura de datos que permite representar espacios volumétricos, donde se diferencian áreas libres de obstáculos, con obstáculos y desconocidas. El segundo de los bloques funcionales utiliza un algoritmo de planificación de caminos basado en muestreos aleatorios del espacio de configuraciones (C-Space) del vehículo. El algoritmo utilizado ha sido modificado para (re)planificar los caminos de acuerdo a la información incrementalmente adquirida del entorno. Finalmente, el coordinador se encarga de iniciar los dos bloques previamente mencionados, así como enviar los puntos resultantes del planificador a los controladores del vehículo. Por último, se presenta la validación de nuestro sistema mediante resultados en entornos reales y de simulación utilizando el vehículo SPARUS-II.

Riesgos operacionales en proyectos de minería subterránea
Authors: Guerrero Useda María Eugenia
Published: July 2017

El proyecto del que se derivó este escrito buscó construir una matriz de riesgos operacionales en empresas con proyectos mineros localizados en la región andina colombiana. Siguiendo un enfoque metodológico mixto que combinó investigación documental, observaciones in situ y análisis semicuantitativo, fueron establecidos algunos de los eventos operacionales altamente probables y de consecuencias nefastas sobre la contabilidad de las empresas, la salud ambiental y el patrimonio nacional. A los riesgos operacionales, definidos desde Basilea II como los que generan pérdidas por eventos externos y por fallos en los procesos, personal y sistemas internos, se atribuye la mayor incertidumbre sobre los objetivos fijados por las empresas mineras. Con todo, el análisis de riesgo en las grandes empresas de este sector, lejos de estimar los eventos con pérdida de vidas humanas y de biodiversidad, se enfoca al tratamiento de factores que impiden operar bajo el esquema 24/7/365; así, se relega a un segundo plano factores asociados a la salud y seguridad de las personas y de los ecosistemas involucrados en sus proyectos. Además de los peligros a los que se exponen los mineros por trabajar en atmósferas explosivas, espacios confinados, con techos y pisos frágiles, ambientes oscuros, altas temperaturas y aire impuro, los contaminantes físicos y químicos generados durante las exploración y la extracción deterioran la salud de los mineros por daños auditivos, daños en el sistema nervioso, alergias, enfermedades en las vías respiratorias, silicosis y cáncer de pulmón. Como si fuera poco, la acumulación de residuos peligrosos en diques de colas y presas de almacenamiento impactan negativamente los cuerpos de agua, el aire y los suelos, generan pobreza hídrica y pérdida de la biodiversidad. De cara a este escenario, cabe preguntarse: ¿es justo transferir tales riesgos a las comunidades que habitan los territorios mineros?

The Effectiveness of Neural Mobilization for Neuromusculoskeletal Conditions: A Systematic Review and Meta-analysis
Authors: Basson Annalie , Olivier Benita , Ellis Richard , Coppieters Michel , Stewart Aimee , Mudzi Witness
Published: July 2017

Study Design

Systematic review with meta-analysis.

Objectives

To determine the efficacy of neural mobilization (NM) for musculoskeletal conditions with a neuropathic component.

Background

Neural mobilization, or neurodynamics, is a movement-based intervention aimed at restoring the homeostasis in and around the nervous system. The current level of evidence for NM is largely unknown.

Methods

A database search for randomized trials investigating the effect of NM on neuromusculoskeletal conditions was conducted, using standard methods for article identification, selection, and quality appraisal. Where possible, studies were pooled for meta-analysis, with pain, disability, and function as the primary outcomes.

Results

Forty studies were included in this review, of which 17 had a low risk of bias. Meta-analyses could only be performed on self-reported outcomes. For chronic low back pain, disability (Oswestry Disability Questionnaire [0–50]: mean difference, −9.26; 95% confidence interval [CI]: −14.50, −4.01; P<.001) and pain (intensity [0–10]: mean difference, −1.78; 95% CI: −2.55, −1.01; P<.001) improved following NM. For chronic neck-arm pain, pain improved (intensity: mean difference, −1.89; 95% CI: −3.14, −0.64; P<.001) following NM. For most of the clinical outcomes in individuals with carpal tunnel syndrome, NM was not effective (P>.11) but showed some positive neurophysiological effects (eg, reduced intraneural edema). Due to a scarcity of studies or conflicting results, the effect of NM remains uncertain for various conditions, such as postoperative low back pain, cubital tunnel syndrome, and lateral epicondylalgia.

Conclusion

This review reveals benefits of NM for back and neck pain, but the effect of NM on other conditions remains unclear. Due to the limited evidence and varying methodological quality, conclusions may change over time.

Level of Evidence

Therapy, level 1a. J Orthop Sports Phys Ther 2017;47(9):593–615. Epub 13 Jul 2017. doi:10.2519/jospt.2017.7117
Assessment of Psychometric Properties of Various Balance Assessment Tools in Persons With Cervical Spondylotic Myelopathy
Authors: Chiu Alice Y.Y. , Pang Marco Y.C.
Published: July 2017

Study Design

Clinical measurement, cross-sectional, repeated-measures design.

Background

Persons with cervical spondylotic myelopathy (CSM) are known to have balance impairments. The psychometric properties of various balance assessment tools have not been evaluated in this population.

Objective

To examine the floor and ceiling effects, item difficulty and item discrimination index, internal consistency, reliability, and validity of the Balance Evaluation Systems Test (BESTest), Mini-BESTest, Brief BESTest, and Berg Balance Scale (BBS) in persons with CSM.

Methods

Seventy-two individuals with CSM were evaluated with the above balance scales. Thirty-two were assessed by a second rater on the same day to establish interrater reliability, and by the same rater 1 to 2 days later to assess test-retest reliability.

Results

Of the 4 balance tools, only the BBS showed a substantial ceiling effect (skewness, γ1<−1.0). The BBS also had the highest proportion (greater than 80%) of easy items. The item discrimination index was greater than 0.4 for all items in the 4 balance scales. All balance tests showed good internal consistency (Cronbach α>0.8), with excellent test-retest (intraclass correlation coefficient [ICC]2,1>0.80) and interrater reliability (ICC2,1>0.80). In addition, all balance tests were strongly correlated with one another (ie, concurrent validity), and with the modified Japanese Orthopaedic Association score (ie, convergent validity). Their correlations with the Abbreviated Mental Test were low (ie, discriminant validity). All 4 balance tests could adequately identify fallers and users of mobility aids (area under the curve, >0.8) (ie, known-groups validity).

Conclusion

The Brief BESTest is the most preferred tool for persons with CSM because of its excellent reliability, validity, and short administration time, whereas the BBS is the least preferred due to its substantial ceiling effect.

Influence of 1-phenoxy-2-propanol on blood profile of common carp
Authors: Czerniak Ewa , Gomułka Piotr , Dągowski Jakub
Published: July 2017

1-phenoxy-2-propanol is a common and effective anaesthetic for aquatic organisms such as bivalves and pulmonates. However, there are no data regarding its influence on fish organisms. In the present study the anaesthetic efficacy of 1-phenoxy-2-propanol and its influence on biochemical and haematological blood indices of juvenile common carp were studied. For blood profile test, fish were divided into four groups (n = 10). The haematological and blood biochemical profiles of common carp were evaluated 10 min and 24 h after anaesthesia with 1-phenoxy-2-propanol (400 mg·dm-3) and compared to non-anaesthetized control groups. Significant changes (P < 0.05) in red blood cell indices and in white blood cell count were found as well. Increased concentrations of glucose, ammonia and inorganic phosphates indicate that stress reaction occurred. No changes in total protein, globulin, triacylglycerols, alkaline phosphatase, aspartate aminotransferase and calcium were found. Although exposure to 1-phenoxy-2-propanol caused a moderate, temporary stress response in examined fish, we can state that 1-phenoxy-2-propanol can be used as an effective anaesthetic for common carp.

Concerned about Going Concern: When do Entities in Liquidation have to be Considered a Non-Going Concern According to IFRS?
Authors: Hasslinger Marius , Olbrich Michael , Rapp David
Published: July 2017

The rejection of the going concern premise as the underlying assumption of financial statements has farreaching consequences for accounting. For that reason, it is vitally important to identify the appropriate point in time at which the entity can no longer be regarded as a going concern. Focussing on entities that voluntarily decided to liquidate their operations, the analysis shows that both the IFRS taxonomy and the accounting literature are rather vague on the question of the point in time at which the going concern premise is no longer appropriate. Therefore, we identify the reporting stages that are necessary in the liquidation phase. Contrary to expectations, the paper argues that the going concern assumption should not be immediately abandoned, as retaining it can provide users of financial statements with decisionuseful information. In fact, the paper recommends a value chain based approach. Accordingly, the going concern assumption should not be rejected before the entity has terminated its activities at all stages of its value chain.
M5' and Mars Based Prediction Models for Properties of Self-compacting Concrete Containing Fly Ash
Authors: Kaveh Ali
Published: July 2017

The main purpose of this paper is to predict the properties (mechanical and rheological) of the self-compacting concrete (SCC) containing fly ash as cement replacement by using two decision tree algorithms: M5′ and Multivariate adaptive regression splines (Mars). The M5′ algorithm as a rule based method is used to develop new practical equations while the MARS algorithm besides its high predictive ability is used to determine the most important parameters. To achieve this purpose, a data set containing 114 data points related to effective parameters affect on SSC properties is used. A gamma test is employed to determine the most effective parameters in prediction of the compressive strength at 28 days, the V-funnel time, the slump flow, and the L-box ratio of SCC. The results from this study suggests that tree based models perform remarkably well in predicting the properties of the self-compacting concrete containing fly ash as cement replacement.
Assays to Monitor Autophagy in Saccharomyces cerevisiae
Authors: Torggler Raffaela , Papinski Daniel , Kraft Claudine
Published: July 2017

Autophagy is an intracellular process responsible for the degradation and recycling of cytoplasmic components. It selectively removes harmful cellular material and enables the cell to survive starvation by mobilizing nutrients via the bulk degradation of cytoplasmic components. While research over the last decades has led to the discovery of the key factors involved in autophagy, the pathway is not yet completely understood. The first studies of autophagy on a molecular level were conducted in the yeast Saccharomyces cerevisiae. Building up on these studies, many homologs have been found in higher eukaryotes. Yeast remains a highly relevant model organism for studying autophagy, with a wide range of established methods to elucidate the molecular details of the autophagy pathway. In this review, we provide an overview of methods to study both selective and bulk autophagy, including intermediate steps in the yeast Saccharomyces cerevisiae. We compare different assays, discuss their advantages and limitations and list potential applications.
Overview of Compressed Air Energy Storage and Technology Development
Authors: Wang Jidai , Lu Kunpeng , Ma Lan , Wang Jihong , Dooner Mark , Miao Shihong , Li Jian , Wang Dan
Published: July 2017

With the increase of power generation from renewable energy sources and due to their intermittent nature, the power grid is facing the great challenge in maintaining the power network stability and reliability. To address the challenge, one of the options is to detach the power generation from consumption via energy storage. The intention of this paper is to give an overview of the current technology developments in compressed air energy storage (CAES) and the future direction of the technology development in this area. Compared with other energy storage technologies, CAES is proven to be a clean and sustainable type of energy storage with the unique features of high capacity and long-duration of the storage. Its scale and cost are similar to pumped hydroelectric storage (PHS), thus CAES has attracted much attention in recent years while further development for PHS is restricted by the availability of suitable geological locations. The paper presents the state-of-the-art of current CAES technology development, analyses the major technological barriers/weaknesses and proposes suggestions for future technology development. This paper should provide a useful reference for CAES technology research and development strategy.
An Assisted Workflow for the Early Design of Nearly Zero Emission Healthcare Buildings
Authors: Sleiman Hassan , Hempel Steffen , Traversari Roberto , Bruinenberg Sander
Published: July 2017

Energy efficiency in buildings is one of the main goals of many governmental policies due to their high impact on the carbon dioxide emissions in Europe. One of these targets is to reduce the energy consumption in healthcare buildings, which are known to be among the most energy-demanding building types. Although design decisions made at early design phases have a significant impact on the energy performance of the realized buildings, only a small portion of possible early designs is analyzed, which does not ensure an optimal building design. We propose an automated early design support workflow, accompanied by a set of tools, for achieving nearly zero emission healthcare buildings. It is intended to be used by decision makers during the early design phase. It starts with the user-defined brief and the design rules, which are the input for the Early Design Configurator (EDC). The EDC generates multiple design alternatives following an evolutionary algorithm while trying to satisfy user requirements and geometric constraints. The generated alternatives are then validated by means of an Early Design Validator (EDV), and then, early energy and cost assessments are made using two early assessment tools. A user-friendly dashboard is used to guide the user and to illustrate the workflow results, whereas the chosen alternative at the end of the workflow is considered as the starting point for the next design phases. Our proposal has been implemented using Building Information Models (BIM) and validated by means of a case study on a healthcare building and several real demonstrations from different countries in the context of the European project STREAMER.
Effects of Physico-Chemical Post-Treatments on the Semi-Continuous Anaerobic Digestion of Sewage Sludge
Authors: Tian Xinbo , Trzcinski Antoine
Published: July 2017

Sludge production in wastewater treatment plants is increasing worldwide due to the increasing population. This work investigated the effects of ultrasonic (ULS), ultrasonic-ozone (ULS-Ozone) and ultrasonic + alkaline (ULS+ALK) post-treatments on the anaerobic digestion of sewage sludge in semi-continuous anaerobic reactors. Three conditions were tested with different hydraulic retention times (HRT, 10 or 20 days) and sludge recycle ratios (R = QR/Qin (%): 50 or 100%). Biogas yield increased by 17.8% when ULS+ALK post-treatment was applied to the effluent of a reactor operating at 20 days HRT and at a 100% recycle ratio. Operation at 10 days HRT also improved the biogas yield (277 mL CH4/g VSadded (VS: volatile solids) versus 249 mL CH4/g VSadded in the control). The tested post-treatment methods showed 4–7% decrease in effluent VS. The post-treatment resulted in a decrease in the cellular ATP (Adenosine tri-phosphate) concentration indicating stress imposed on microorganisms in the reactor. Nevertheless, this did not prevent higher biogas production. Based on the results, the post-treatment of digested sludge or treating the sludge between two digesters is an interesting alternative to pre-treatments.

Soil respiration is a major carbon pathway sensitive to environmental changes. Using prescribed burnings to reduce fuel accumulation and lower risks of large-scale wildfires has recently become more important. Prescribed burning can significantly alter the soil environment, but its effect in practice on soil respiration is not sufficiently understood. We evaluated the effects of prescribed burning on soil respiration before and after burning (May–July 2016). Prescribed burning was conducted in two natural pine areas by comparing a mixed stand of Pinus nigra Arn. ssp. salzmannii with Pinus pinaster Ait. to a pure stand of Pinus nigra Arn. ssp. salzmannii in the central Iberian Peninsula. Soil respiration was measured by an EGM-4 (Environmental Gas Monitor) infrared gas analyser in both burned and unburned (control) plots. Burnings were low-intensity, and slightly more energetic in the pure stand given its larger litter volume. Post-burning soil respiration followed a similar evolution to that in the control plots, but was greater in the pure stand burned zone and slightly lower in the burned plots in the mixed stand. No significant differences were found in any stand. Soil respiration significantly changed in temporal evolution due to increasing temperatures when summer began. We conclude that prescribed fire induces no changes in SR immediately after fire. This study helps understand how prescribed burnings can affect soil respiration in pure and mixed Spanish black pine forest stands.
Robust Image Embedded Watermarking Using DCT and Listless SPIHT
Authors: Shivani J. , Senapati Ranjan
Published: July 2017

This paper presents a DCT-based (DCT: discrete cosine transform) listless set partitioning in hierarchical trees (SPIHT) digital watermarking technique that is robust against several common attacks such as cropping, filtering, sharpening, noise, inversion, contrast manipulation, and compression. The proposed technique is made further robust by the incorporation of the Chinese remainder theorem (CRT) encryption technique. Our scheme is compared with the recently proposed CRT-based DCT technique, CRT-based spatial domain watermarking, and DCT-based inter block correlation techniques. Extensive simulation experiments show better robustness in common image manipulations and, at the same time, the proposed technique successfully makes the watermark perceptually invisible. A better Tamper Assessment Function (TAF) value of 2–15% and a better Normalized Correlation (NC) is achieved compared to some of the above techniques. In particular, the proposed technique shows better robustness on compression attacks at moderate to higher compression ratios. It is possible to maintain the imperceptibility and low TAF for various values by doubling the capacity of the watermark.

Heavy metal and metalloid (Cr, Pb, Cd, Zn, Cu, Ni, As and Hg) concentrations in groundwater from 19 typical sites throughout a typical brownfield were detected. Mean concentrations of toxic metals in groundwater decreased in the order of Cr > Zn > Cu > Cd > Ni > Pb > Hg > As. Concentration of Cr6+ in groundwater was detected to further study chromium contamination. Cr6+ and Cd in groundwater were recommended as the priority pollutants because they were generally 1399-fold and 12-foldgreater than permissible limits, respectively. Owing to the fact that a waterproof curtain (WPC) in the brownfield is about to pass the warranty period, a steady two-dimensional water quality model and health risk assessment were applied to simulate and evaluate adverse effects of Cr6 + and Cd on the water quality of Xiangjiang River and the drinking-water intake of Wangcheng Waterworks. The results indicated that when groundwater in the brownfield leaked with valid curtain prevention, the water quality in Xiangjiang River and drinking-water intake downstream were temporarily unaffected. However, if there was no curtain prevention, groundwater leakage would have adverse impact on water quality of Xiangjiang River. Under the requirements of Class III surface water quality, the pollution belt for Cr6+ was 7500 m and 200 m for Cd. The non-carcinogenic risk of toxic metals in Xiangjiang River exceeded the threshold in a limited area, but did not threaten Wangcheng Waterworks. By contrast, the carcinogenic risk area for adults was at a transverse distance of 200 m and a longitudinal distance of 18,000 m, which was close to the Wangcheng Waterworks (23,000 m). Therefore, it was essential to reconstruct the WPC in the brownfield for preventing pollution diffusion.
SCMDOT: Spatial Clustering with Multiple Density-Ordered Trees

With the rapid explosion of information based on location, spatial clustering plays an increasingly significant role in this day and age as an important technique in geographical data analysis. Most existing spatial clustering algorithms are limited by complicated spatial patterns, which have difficulty in discovering clusters with arbitrary shapes and uneven density. In order to overcome such limitations, we propose a novel clustering method called Spatial Clustering with Multiple Density-Ordered Trees (SCMDOT). Motivated by the idea of the Density-Ordered Tree (DOT), we firstly represent the original dataset by the means of constructing Multiple Density-Ordered Trees (MDOT). In the constructing process, we impose additional constraints to control the growth of each Density-Ordered Tree, ensuring that they all have high spatial similarity. Furthermore, a series of MDOT can be successively generated from regions of sparse areas to the dense areas, where each Density-Ordered Tree, also treated as a sub-tree, represents a cluster. In the merging process, the final clusters are obtained by repeatedly merging a suitable pair of clusters until they satisfy the expected clustering result. In addition, a heuristic strategy is applied during the process of our algorithm for suitability for special applications. The experiments on synthetic and real-world spatial databases are utilised to demonstrate the performance of our proposed method.

Although cisplatin is an anticancer drug that has activity against malignant tumor, it often causes nephrotoxicity. Previous reports have confirmed that the saponins from the leaves of P. quinquefolium (PQS) exerted many pharmacological activities. However, the renoprotective effects of PQS were still unknown. The purpose of the present research was to discuss renoprotective effect of PQS in a mouse model of cisplatin-induced acute kidney injury (AKI). The levels of blood urea nitrogen (BUN) and serum creatinine (CRE) were evidently increased in cisplatin-intoxicated mice, which were reversed by PQS. Renal oxidative stress, evidenced by increased malondialdehyde (MDA) level and decline of glutathione (GSH) and superoxide dismutase (SOD) activities, was significantly alleviated by PQS pretreatment. The suppression of inflammatory response by PQS was realized through the decrease the mRNA expression levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in kidney tissues, which were measured by quantitative real-time polymerase chain reaction (qRT-PCR). Simultaneously, the overexpression of cytochrome P450 E1 (CYP2E1) and heme oxygenase-1 (HO-1) were attenuated by PQS. Furthermore, the effects of Western blotting demonstrated that PQS administration significantly suppressed the protein expression levels of nicotinamide adenine dinucleotide phosphate oxidase type 4 (Nox4), cleaved Caspase-3, cleaved Caspase-9, Bax, nuclear factor-κB (NF-κB), cyclooxygenase-2 (COX-2), and inducible nitric oxide synthase (iNOS), suggesting the inhibition of apoptosis and inflammation response. Overall, PQS may possess protective effects in cisplatin-induced AKI through suppression of oxidative stress, inflammation and apoptosis.
Programmed Cell Death 1 (PD-1) and Cytotoxic T Lymphocyte-Associated Antigen 4 (CTLA-4) in Viral Hepatitis

Published: July 2017

Virus-specific cluster of differentiation 8 (CD8+) cytotoxic T cells (CTL) recognize viral antigens presented on major histocompatibility complex (MHC) class I chains on infected hepatocytes, with help from CD4+ T cells. However, this CTL response is frequently weak or undetectable in patients with chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. Programmed cell death 1 (PD-1) and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) are receptors in the CD28 family of costimulatory molecules, providing inhibitory signals to T cells. The overexpressions of PD-1 and CTLA-4 in patients with viral infection have been shown to associate with functional impairment of virus-specific T cells. In acute viral hepatitis, PD-1 and CTLA-4 are up-regulated during the symptomatic phase, and then down-regulated after recovery. These findings suggest that PD-1 and CTLA-4 have protective effects as inhibitory molecules to suppress cytotoxic T cells which induce harmful destruction of viral infected hepatocytes in self-limited viral hepatitis. In chronic viral hepatitis, the extended upregulations of PD-1 and CTLA-4 are associated with T cell exhaustion and persistent viral infection, suggesting positive correlations between expression of immune inhibitory factors and the chronicity of viral disease. In this review, we summarize recent literature relating to PD-1, CTLA-4, and other inhibitory receptors in antigen-specific T cell exhaustion in viral hepatitis, including hepatitis A, B, C, and others.
