Cues to Viewing Distance for Stereoscopic Depth Constancy

A veridical estimate of viewing distance is required in order to determine the metric structure of objects from binocular stereopsis. One example of a judgment of metric structure, which we used in our experiment, is the apparently circular cylinder task (E B Johnston, 1991 Vision Research 31 1351 – 1360). Most studies report underconstancy in this task when the stimulus is defined purely by binocular disparities. We examined the effect of two factors on performance: (i) the richness of the cues to viewing distance (using either a naturalistic setting with many cues to viewing distance or a condition in which the room and the monitors were obscured from view), and (ii) the range of stimulus disparities (cylinder depths) presented during an experimental run. We tested both experienced subjects (who had performed the task many times before under full-cue conditions) and naive subjects. Depth constancy was reduced for the naïve subjects (from 62% to 46%) when the position of the monitors was obscured. Under similar conditions, the experienced subjects showed no reduction in constancy. In a second experiment, using a forced-choice method of constant stimuli, we found that depth constancy was reduced from 64% to 23% in naive subjects and from 77% to 55% in experienced subjects when the same set of images was presented at all viewing distances rather than using a set of stimulus disparities proportional to the correct setting. One possible explanation of these results is that, under reduced-cue conditions, the range of disparities presented is used by the visual system as a cue to viewing distance.
Increased mitochondrial electron transport chain activity at complex I is regulated by N-acetylcysteine in lymphocytes of patients with systemic lupus erythematosus.

AIMS Systemic lupus erythematosus (SLE) patients' peripheral blood lymphocytes (PBL) show mitochondrial dysfunction and oxidative stress. To determine the electrochemical bases of mitochondrial dysfunction, we measured electron transport chain (ETC) activity and its regulation by N-acetylcysteine (NAC) that reversed glutathione depletion and improved disease activity in SLE. ETC activity was assessed in PBL of 69 SLE patients and 37 healthy donors. Negatively isolated T cells were examined in 7 SLE patients, 11 healthy donors, and 10 nonlupus inflammatory arthritis (IA) donors. RESULTS O₂ consumption (in nmol/ml/min) by lupus PBL was increased at baseline (SLE: 2.492±0.196, control: 2.137±0.153; p=0.027) and with complex IV substrates (SLE: 7.722±0.419, control: 7.006±0.505; p=0.028). SLE PBL consumed more O₂ upon in-chamber T-cell activation (p=0.012). After overnight T-cell stimulation, ETC activity of SLE PBL was 2.27-fold increased through complex I (SLE: 1.606±0.273, control: 0.709±0.169; p=0.001) and, to a lesser extent, through complex IV. Likewise, complex I activity was elevated in negatively isolated "untouched" T cells of SLE patients (1.816±0.180) relative to healthy controls (0.917±0.094; p=0.0003) and IA disease controls studied in parallel (1.057±0.199; p=0.0308). NAC diminished O₂ consumption through complex I and H₂O₂ levels both in SLE and in control PBL. INNOVATION O₂ consumption was found to be increased in SLE patients' PBL relative to control subjects evaluated in parallel. ETC complex I is identified as the main source of oxidative stress in SLE. CONCLUSIONS Lupus PBL exhibit increased O₂ consumption through mitochondrial ETC complex I that is inhibited by NAC, which may have therapeutic efficacy through reducing oxidative stress in SLE.
Socio-Cultural Values of Ecosystem Services from Oak Forests in the Eastern Himalaya

Identification and assessment of socio-cultural values of ecosystem services are increasingly important for the planning and management of forest resources. Key information necessary is how different forest user groups perceive and prioritize different ecosystem services based on their local setting. We assessed the socio-cultural values of ecosystem services of high-altitude oak forests in Western Bhutan using participatory approaches with two important forest users: local communities and forest experts. We found that these forests serve as a pool of 22 ecosystem services under four MEA categories of provisioning (9), regulating (8), supporting (2), and cultural (3) services. Fresh water was unanimously identified as the most valuable service, as well as the most vulnerable, by both the groups. The priorities of local communities inclined towards provisioning and cultural services due to their dependence on these services for their livelihood and wellbeing. Forest experts’ priorities were more evenly spread over three categories of services: provisioning, regulating, and supporting services, reflecting their broader interest in resource management, biodiversity conservation, and climate change mitigation. Several regulating and supporting services were not easily identified by many villagers, suggesting that bridging the priorities of local interests with broader national forestry goals may require public partnerships and integrated decision-making about the entire suite of ecosystem services. Several management interventions proposed by the groups were presented for consideration by local users, scientists, and policy makers. For all ongoing and future ecosystem service assessments, we recommend the integration of socio-cultural values with biophysical and monetary assessments to fully value the benefits from the high-altitude oak forests.
IP-10 release assays in the diagnosis of tuberculosis infection: current status and future directions

The current state-of-the-art tests for infection with Mycobacterium tuberculosis – the IFN-γ release assays – rely on accurate measurement of the cytokine IFN-γ. Many other potential biomarkers are expressed in concert with IFN-γ, and IP-10 in particular has shown promising results. IP-10 is produced in large amounts, allowing for the development of new and simplified test platforms, such as lateral flow. In this review, we summarize the results of 22 clinical studies exploring the use of IP-10 as an alternative marker to IFN-γ. The studies report that diagnostic accuracy of IP-10 is on par with IFN-γ, but also that IP-10 may be more robust in young children and in HIV-infected individuals with low CD4 cell counts. We conclude the review by presenting limitations of the published works and outline recent developments and future directions.
The use of a novel MUC1 antibody to identify cancer stem cells and circulating MUC1 in mice and patients with pancreatic cancer

MUC1 is over‐expressed and aberrantly glycosylated in >60% of human pancreatic cancer (PC). Development of novel approaches for detection and/or targeting of MUC1 are critically needed and should be able to detect MUC1 on PC cells (including cancer stem cells) and in serum.
Construal level, rumination, and psychological distress in palliative care

Patients with a life‐limiting illness, such as cancer, and their carers experience elevated psychological distress. However, the psychological mechanisms underpinning distress in palliative care have been little studied. Recent theories predict that individuals who experience increased uncertainty in the context of ongoing difficulties, such as palliative patients and their carers, will (a) think more abstractly; (b) ruminate more; and (c) be more distressed.
Autologous transplantation of peripheral blood progenitor cells mobilized by chemotherapy with or without G-CSF (filgrastim) in resistant lymphoproliferative diseases: enhanced hemopoietic recovery with filgrastim primed progenitors.

BACKGROUND AND METHODS Bone marrow transplantation is increasingly used to overcome the bone marrow toxicity from myeloblative therapy. Peripheral blood progenitor cell transplantation (PBPCT) has been recognized as an alternative source of bone marrow for hemopoietic recovery after myeloblative therapy. In the steady state condition hemopoietic progenitors are scarce in peripheral blood; chemotherapy and growth factors are both able to increase PBPCs. Twenty-five patients affected by resistant lymphoproliferative diseases [4 multiple myeloma (MM), 19 non Hodgkin's lymphoma (NHL) and 2 Hodgkin's disease (HD)] were submitted to autologous peripheral blood progenitor cell transplantation (PBPCT). PBPCs were collected after chemotherapy (CT) alone (8 patients) or plus filgrastim (17 patients). Filgrastim was not administered after PBPCT in any case. RESULTS AND CONCLUSIONS A statistically significant difference between the two groups was found for the following parameters: number of leukaphereses administered, amount of CFU-GM infused, time to hemopoietic recovery, amount of supportive care, number of days of antibiotic therapy, length of hospitalization. PBPCs primed with filgrastim CT appeared to be markedly superior to CT-recruited PBPCs in reducing the period of neutropenia and, surprisingly, of thrombocytopenia. Reduction in hematologic toxicity resulted in a decrease of transplantation-related toxicity and mortality, even in elderly and/or heavily pretreated patients.
Patterns of Care and Survival in Non Small Cell Lung Cancer: 15 Years’ Experience in a General Hospital

Background Transferring results derived from clinical research into practice is particularly difficult in lung cancer where clear indications for treatment are defined only for selected subgroups of patients. Studies on hospital-based lung cancer population could provide data for quantifying this issue. Patients and methods This was a follow-up study of consecutive, first-diagnosis cases referred to the in-and outpatient cancer clinics of a large italian general hospital between January 1975 and December 1990. Data were collected from medical records and recorded on ad hoc standardized forms. Analysis focused on changes in distribution over time of patient-related characteristics, prevalence of specific treatment strategies and survival of the study population. Results 1345 primary non small cell lung cancer cases were reviewed and 1125 were fully evaluable. In early stages (510/1125, 45%) only 237 patients actually underwent surgery. In this group surgery increased from 36 to 69% whereas chemotherapy decreased from 58 to 15%. In the advanced group (615/1125, 55%) chemotherapy was the preferred treatment but combined modalities tripled over time (from 4 to 12%). No significant changes in survival were observed within each group over time. Conclusion Despite changes in the therapeutic approaches, mortality from lung cancer does not seem reduced over time. Since the proportion of cases that could potentially benefit from “active” treatments is small, for the large majority of patients a switch in clinical research from a cure to a careoriented strategy should be considered.
Sprouty Proteins Are Negative Regulators of Interferon (IFN) Signaling and IFN-inducible Biological Responses*

Background: The potential involvement of Spry proteins in IFN signaling is unknown. Results: Type I IFN treatment results in up-regulation of Spry proteins, which negatively control generation of IFN responses. Conclusion: Spry proteins play important regulatory roles in IFN signaling and the generation of the biological effects of IFNs. Significance: This study provides evidence for the existence of a key signaling pathway that controls IFN responses. Interferons (IFNs) have important antiviral and antineoplastic properties, but the precise mechanisms required for generation of these responses remain to be defined. We provide evidence that during engagement of the Type I IFN receptor (IFNR), there is up-regulation of expression of Sprouty (Spry) proteins 1, 2, and 4. Our studies demonstrate that IFN-inducible up-regulation of Spry proteins is Mnk kinase-dependent and results in suppressive effects on the IFN-activated p38 MAP kinase (MAPK), the function of which is required for transcription of interferon-stimulated genes (ISGs). Our data establish that ISG15 mRNA expression and IFN-dependent antiviral responses are enhanced in Spry1,2,4 triple knock-out mouse embryonic fibroblasts, consistent with negative feedback regulatory roles for Spry proteins in IFN-mediated signaling. In other studies, we found that siRNA-mediated knockdown of Spry1, Spry2, or Spry4 promotes IFN-inducible antileukemic effects in vitro and results in enhanced suppressive effects on malignant hematopoietic progenitors from patients with polycythemia vera. Altogether, our findings demonstrate that Spry proteins are potent regulators of Type I IFN signaling and negatively control induction of Type I IFN-mediated biological responses.
Impact of Mesh Fixation on Chronic Pain in Total Extraperitoneal Inguinal Hernia Repair (TEP): A Nationwide Register-based Study

Background:Mesh fixation is used to prevent recurrence at the potential risk for chronic pain in TEP. The aim was to compare the impact of permanent fixation (PF) with no fixation (NF)/nonpermanent fixation (NPF) of mesh on chronic pain after TEP repair for primary inguinal hernia. Methods:Men, 30 to 75 years old, consecutively registered in the Swedish Hernia Register for a TEP primary repair in 2005 to 2009, were included in a mail survey using SF-36 and the Inguinal Pain Questionnaire (IPQ). Primary endpoint was IPQ question “Did you have pain during past week that could not be ignored. ” Risk factors for chronic pain and recurrent operations were analyzed. Results:A total of 1110 patients were included (325 PF, 785 NF/NPF) with 7.7% reporting pain at median 33 months follow-up. No difference regarding primary endpoint pain (P < 0.462), IPQ and SF-36 subscales were seen. Recurrent operation was carried out in 1.4% during 7.5 years follow-up with no difference between PF- and NF-groups including subgroups of medial hernias. All SF-36 subscale-scores were equal to or better than the Swedish norm. A postoperative complication was a risk factor for chronic pain (OR 2.44, 95% CI 1.23–5.25, P < 0.023). Conclusions:The TEP procedure for primary inguinal hernia repair in men is associated with a low frequency of chronic pain and recurrent operations, with no difference between permanent fixation and no/nonpermanent fixation of mesh in a nationwide population-based study. TEP without fixation reduces costs and is safe for all patients.
Orangutan Cultures and the Evolution of Material Culture

Geographic variation in some aspects of chimpanzee behavior has been interpreted as evidence for culture. Here we document similar geographic variation in orangutan behaviors. Moreover, as expected under a cultural interpretation, we find a correlation between geographic distance and cultural difference, a correlation between the abundance of opportunities for social learning and the size of the local cultural repertoire, and no effect of habitat on the content of culture. Hence, great-ape cultures exist, and may have done so for at least 14 million years.
Maternal versus paternal inheritance of HLA class I alleles among HIV-infected children: consequences for clinical disease progression

Objective: When children acquire HIV infection from their mothers (with whom they share at least 50% of their HLA alleles), they acquire virus with a history of encounter with maternal HLA-mediated immune responses. We investigated whether maternal HLA selection pressures on the virus would adversely influence clinical outcomes of HIV-infected children. Methods: We tested whether time to AIDS diagnosis or death, among a cohort of 59 HIV-infected children in New York City followed from birth for up to 12 years, was associated with maternally- or paternally-inherited child HLA class I alleles, and with HLA similarity between mother and child. Results: HIV-infected children with an HLA allele usually associated with slow disease experienced a slower progression to AIDS or death only if the allele was paternally inherited. If the allele was present in the mother, no association was observed. Children who were homozygous or who shared both alleles with their mothers at more than one HLA class I locus were more likely to progress to AIDS or death than other children (relative hazard, 3.46; 95% confidence interval, 1.24–9.71). Conclusion: Genetic similarity between mother and child may compromise the child's capacity to control HIV replication when the virus is acquired from the mother. HLA-mediated selective pressures on the virus in a transmitting mother–infant pair may undermine future HLA-mediated viral control in the child.
Association of sick building syndrome with neuropathy target esterase (NTE) activity in Japanese

Sick building syndrome (SBS) is a set of several clinically recognizable symptoms reported by occupants of a building without a clear cause. Neuropathy target esterase (NTE) is a membrane bound serine esterase and its reaction with organophosphates (OPs) can lead to OP‐induced delayed neuropathy (OPIDN) and nerve axon degeneration. The aim of our study was to determine whether there was a difference in NTE activity in the peripheral blood mononuclear cells (PBMCs) of Japanese patients with SBS and healthy controls and whether PNPLA6 (alias NTE) gene polymorphisms were associated with SBS. We found that the enzymatic activity of NTE was significantly higher (P < 0.0005) in SBS patients compared with controls. Moreover, population with an AA genotype of a single nucleotide polymorphism (SNP), rs480208, in intron 21 of the PNPLA6 gene strongly reduced the activity of NTE. Fifty‐eight SNP markers within the PNPLA6 gene were tested for association in a case–control study of 188 affected individuals and 401 age‐matched controls. Only one SNP, rs480208, was statistically different in genotype distribution (P = 0.005) and allele frequency (P = 0.006) between the cases and controls (uncorrected for testing multiple SNP sites), but these were not significant by multiple corrections. The findings of the association between the enzymatic activity of NTE and SBS in Japanese show for the first time that NTE activity might be involved with SBS. © 2013 Wiley Periodicals, Inc.

Effect of intestinal lymphatic circulation blockage in two-hit rats.

AIM To study the effect of blocking intestinal lymphatic circulation in two-hit rats and explore the significance of intestinal lymphatic circulation in two-hit. METHODS Wistar rats were divided equally into three groups: mesenteric lymph duct ligation group, non-ligation group and sham group. Mesenteric lymph was diverted by ligation of mesenteric lymph duct, and the two-hit model was established by hemorrhage and lipopolysaccharide (LPS) methods. All rats were sampled for serum pre-experiment and 24 h post-experiment. The organs including kidney, liver, lung and heart were collected for pathomorphologic observation and biochemical investigation. The nitric oxide (NO), malondialdehyde (MDA) and superoxide dismutase (SOD) were determined in serum and tissue homogenate. RESULTS Pathomorphology study showed that the structures of kidney, lung, liver and heart tissues were normal in sham group; congestion, degeneration and necrosis in non-ligation group; but only mild lesions in ligation group. After two-hits, the contents of AST, ALT, BUN, Cr and LDH-1 in the serum of non-ligation group and ligation group were obviously higher than that in pre-experiment group and sham group, but obviously lower than that in non-ligation group. The contents of NO(2)(-)/NO(3)(-), NOS, iNOS and MDA in the serum of non-ligation group were significantly increased, compared with pre-experiment and sham group, but SOD was significantly lower. These parameters were significantly different in ligation group compared with that in sham group, but NO2-/NO3-, iNOS and MDA in ligation group were significantly lower than that in non-ligation group. CONCLUSION Ligation of mesenteric lymph duct could improve the disturbance of organic function and morphologic damage in two-hit rats; the lymphatic mechanism in two-hit should be emphasized.
The estimation of pairwise relationships

Relationships between the individuals of a population have been previously studied from the point of view of prediction. Edwards (1967) suggested that the problem of detailed population structure could also be studied from the point of view of inference. Even where inferences of practical applicability cannot be made, such an approach can increase understanding of the relation between genealogical and genetic structure. In this paper we consider a specific problem which provides an introduction to the ideas and methods of genealogical inference. This is the problem of estimating the pairwise relationship between two individuals on the basis of their phenotypes at several loci. There is no theoretical problem in the extension from pairwise to joint relationship.
Understanding Social Support and the Couple's Relationship Among Women with Depressive Symptoms in Pregnancy

This qualitative study explored the experiences of seven couples where the female partner experienced depressive symptoms during pregnancy. Female and male partners were interviewed together and data was collected and analyzed according to Colaizzi's () phenomenological research design. The interviews yielded the following themes: (a) Challenges and stressors associated with depressive symptoms during pregnancy, (b) Pregnancy's effect on mood states, (c) Relationship dynamics that influence moods, (d) Pregnancy and the influence of mood on relationship dynamics, and (e) Reliance on external sources of support. The findings extend current research and provide insight into possibilities of how to enhance assessment and intervention for women who are depressed during pregnancy by including a relational component. Findings, clinical implications, and future research are discussed.
