Rich forests, rich people? Sustainable finance and its links to forests.

Investment products labelled as sustainable, as well as regulations on sustainable finance, such as the EU taxonomy for sustainable activities, are on the rise globally. While some of these products and regulations include forests and forestry, the forest-sustainable finance nexus is largely unexplored in academic research. This paper systematically analyses the emerging expert debate spanning across the financial and forest sectors. We conducted 51 in-depth qualitative interviews with experts from financial institutions, timberland and impact investors, international organizations, civil society organizations and academia. We chose mainly experts from Europe, as one of the regions spearheading the topic globally. Based on these, we identify five main narratives on the nexus between sustainable finance and forests. These narratives are strikingly different regarding such dimensions as emphasis on risks versus opportunities, preference for public versus private governance and investments, as well as on the sustainability of forest-related investments per se. While financial sector experts are mainly concerned about financial risks, and only partially about deforestation risks, forest sector experts with financial expertise promote investment opportunities either for the asset class, or to increase private investment in tropical forests. In contrast, some experts from both the forest and financial sectors explicitly exclude forests as investable assets for the private sector, seeing them instead as pure public goods. We conclude with underlining the importance of more cross-sectoral dialogue, but also research, to both critically assess and advance the role of sustainable finance policy and practice in supporting forest conservation, restoration, and sustainable management.

Scanning the solutions for the sustainable supply of forest ecosystem services in Europe.

Forests are key components of European multifunctional landscapes and supply numerous forest ecosystem services (FES) fundamental to human well-being. The sustainable provision of FES has the potential to provide responses to major societal challenges, such as climate change, biodiversity loss, or rural development. To identify suitable strategies for the future sustenance of FES, we performed a solution scanning exercise with a group of transdisciplinary forest and FES experts from different European regions. We identified and prioritized fifteen major challenges hindering the balanced provision of multiple FES and identified a series of potential solutions to tackle each of them. The most prominent challenges referred to the increased frequency and impacts of extreme weather events and the normative mindset regarding forest management. The respective solutions pointed to the promotion of forest resilience via climate-smart forestry and mainstreaming FES-oriented management through a threefold strategy focusing on education, awareness raising, and networking. In a subsequent survey, most solutions were assessed as highly effective, transferable, monitorable, and with potential for being economically efficient. The implementation of the solutions could have synergistic effects when applying the notion of leverage points. Seven emerging pathways towards the sustainable supply of FES have been identified. These pathways build on each other and are organized based on their potential for transformation: (1) shifting forest management paradigms towards pluralistic ecosystem valuation; (2) using integrated landscape approaches; (3) increasing forest resilience; (4) coordinating actions between forest-related actors; (5) increasing participation in forest planning and management; (6) continuous, open, and transparent knowledge integration; and (7) using incentive-based instruments to support regulating and cultural FES. These pathways can contribute to the implementation of the new EU Forestry Strategy to support the balanced supply of multiple FES.

Can nature conservation and wood production be reconciled in managed forests? A review of driving factors for integrated forest management in Europe.

Integrated forest management (IFM) can help reconcile critical trade-offs between goals in forest management, such as nature conservation and biomass production. The challenge of IFM is dealing with these trade-offs at the level of practical forest management, such as striving for compromises between biomass extraction and habitat retention. This paper reviews some of the driving factors that influence the integration of nature conservation into forest management. The review was conducted in three steps - a literature review, an expert workshop and an expert-based cooperative analysis. Of 38 driving factors identified, three were prioritised by more of the participants than any of the others: two are socio-cultural factors, identity (how people identify with forest) as well as outreach and education, and one is economic - competitiveness in forest value chains. These driving factors correspond to what are considered in the literature as enablers for IFM. The results reveal that targeted, group-oriented, adaptive and innovative policy designs are needed to integrate nature conservation into forest management. Further, the results reveal that a "one-size-fits-all" governance approach would be ineffective, implying that policy instruments need to consider contextually specific driving factors. Understanding the main driving factors and their overall directions can help to better manage trade-offs between biodiversity conservation and biomass production in European forests.

Reviewing the Use of Resilience Concepts in Forest Sciences.

Purpose of Review: Resilience is a key concept to deal with an uncertain future in forestry. In recent years, it has received increasing attention from both research and practice. However, a common understanding of what resilience means in a forestry context and how to operationalise it is lacking. Here, we conducted a systematic review of the recent forest science literature on resilience in the forestry context, synthesizing how resilience is defined and assessed. Recent Findings: Based on a detailed review of 255 studies, we analysed how the concepts of engineering resilience, ecological resilience and social-ecological resilience are used in forest sciences. A clear majority of the studies applied the concept of engineering resilience, quantifying resilience as the recovery time after a disturbance. The two most used indicators for engineering resilience were basal area increment and vegetation cover, whereas ecological resilience studies frequently focus on vegetation cover and tree density. In contrast, important social-ecological resilience indicators used in the literature are socioeconomic diversity and stock of natural resources. In the context of global change, we expected an increase in studies adopting the more holistic social-ecological resilience concept, but this was not the observed trend. Summary: Our analysis points to the nestedness of these three resilience concepts, suggesting that they are complementary rather than contradictory. It also means that the variety of resilience approaches does not need to be an obstacle for operationalisation of the concept. We provide guidance for choosing the most suitable resilience concept and indicators based on the management, disturbance and application context.

A paradigm for understanding trust and mistrust in medical research: The Community VOICES study.

BACKGROUND: To promote justice in research practice and rectify health disparities, greater diversity in research participation is needed. Lack of trust in medical research is one of the most significant obstacles to research participation. Multiple variables have been identified as factors associated with research participant trust/mistrust. A conceptual model that provides meaningful insight into the interplay of factors impacting trust may promote more ethical research practice and provide an enhanced, actionable understanding of participant mistrust. METHODS: A structured survey was developed to capture attitudes toward research conducted in emergency situations; this article focuses on items designed to assess respondents' level of trust or mistrust in medical research in general. Community-based interviews were conducted in English or Spanish with 355 New York City residents (white 42%, African American 29%, Latino 22%). RESULTS: Generally favorable attitudes toward research were expressed by a majority (85.3%), but many respondents expressed mistrust. Factor analysis yielded four specific domains of trust/mistrust, each of which was associated with different demographic variables: general trustworthiness (older age, not disabled); perceptions of discrimination (African American, Latino, Spanish language preference); perceptions of deception (prior research experience, African American); and perceptions of exploitation (less education). CONCLUSIONS: The four domains identified in the analysis provide a framework for understanding specific areas of research trust/mistrust among disparate study populations. This model offers a conceptual basis for the design of tailored interventions that target specific groups to promote trust of individual researchers and research institutions as well as to facilitate broader research participation.

Social support, intrusive thoughts, and quality of life in breast cancer survivors.

This study explores the moderating effect of social support on the relationship between cancer-related intrusive thoughts and quality of life. Sixty-four breast cancer survivors completed self-report measures of appraisal social support (the disclosure of thoughts and feelings to significant others), cancer-related intrusive thoughts, and quality of life. Controlling for demographic and treatment variables, the negative impact of cancer-related intrusive thoughts on both physical and mental quality of life measures was moderated by appraisal social support. For women with high levels of appraisal support, cancer-related intrusive thoughts had no significant relationship with quality of life. However, for women with low levels of appraisal support, the relationship between cancer-related intrusive thoughts and quality of life was significant and negative. These results suggest that appraisal social support can mitigate the impact of traumatic life events.

Global meaning and psychological adjustment among survivors of bone marrow transplant.

The purpose of the present study was to examine global meaning (i.e. the belief that life has purpose and coherence) and psychological adjustment in survivors of bone marrow transplantation (BMT). Eighty-five survivors of BMT participated in a telephone interview. Regression analyses demonstrated that after controlling for physical functioning, stressor severity, and gender, global meaning was inversely related to global psychological distress and BMT-related psychological distress (i.e. posttraumatic stress disorder-like symptoms related to the cancer treatment). Global meaning was also positively related to mental health aspects of quality of life (e.g. emotional functioning and social functioning). These findings suggest that global meaning may be an important factor in the psychological adjustment of BMT survivors.

Housing status and health care service utilization among low-income persons with HIV/AIDS.

OBJECTIVE: To examine the impact of housing status on health service utilization patterns in low-income HIV-infected adults. DESIGN: A survey of 1,445 HIV-infected Medicaid recipients in New York State between April 1996 and March 1997. MAIN RESULTS: Six percent of study participants were homeless, 24.5% were "doubled-up," and 69.5% were stably housed. Compared with the stably housed, doubled-up and homeless participants were less likely to be seeing a physician regularly (P = .0001), and if seeing a physician, they were likely to have been doing so for a significantly shorter time (P = .02). The homeless were also less likely than either stably housed or doubled-up individuals to see the same physician or group of physicians at each ambulatory visit (P = .007). In addition, a higher proportion of the homeless had made one or more hospital visits over the prior 3 months than the nonhomeless. After multivariate adjustment, doubled-up participants were found to make more emergency room visits, the homeless were less likely to be taking prophylaxis for Pneumocystis carinii pneumonia, and both the doubled-up and the homeless were shown to use slightly more outpatient care than the stably housed. CONCLUSION: Our study documents differences in health care utilization patterns across stably housed, doubled-up, and homeless HIV-infected persons after controlling for health insurance coverage. These differences, especially those pertaining to outpatient services, suggest that the unstably housed may be receiving less adequate health care than the stably housed, and hence may be more likely to experience adverse clinical outcomes.

Suppression of apoptosis by glucocorticoids in glomerular endothelial cells: effects on proapoptotic pathways.

Tumour necrosis factor-alpha (TNF-alpha)- and lipopolysaccharide (LPS)-induced apoptosis of bovine glomerular endothelial cells is now recognized as an important part in the pathogenesis of glomerulonephritis characterized by early mitochondrial cytochrome c release, mitochondrial permeability transition, Bak protein upregulation, Bcl-X(L) protein downregulation and caspase-3 activation. Co-treatment of cells with 10 nM dexamethasone and TNF-alpha or LPS blocked roughly 90% of apoptotic cell death in glomerular endothelial cells. The action of glucocorticoids could be documented in that they prevented all apoptotic markers such as DNA laddering, DNA fragmentation measured by the diphenylamine assay as well as morphological alterations. To mechanistically elucidate the action of glucocorticoids we evaluated whether glucocorticoids elicit a time-dependent effect. For dexamethasone, to maximally inhibit DNA fragmentation a preincubation period was not required. Even if dexamethasone was supplemented 6 h following TNF-alpha or LPS we observed a maximal inhibitory effect. Concerning its influence on TNF-alpha and LPS signal transduction, we found that dexamethasone only partially prevented cytochrome-c-release as a first sign of apoptotic cell death but efficiently blocked mitochondrial permeability transition. Moreover, TNF-alpha- and LPS-induced Bak upregulation, Bcl-X(L)-downregulation, and the activation of caspase-3-like proteases, measured fluorometrically using DEVD-AMC and PARP cleavage, were efficiently blocked by dexamethasone. We postulate that glucocorticoids exert their inhibitory action upstream of the terminal death pathways but downstream of primary receptor mediated signals by blocking pro-apoptotic signals pre- and/or post cytochrome c release and mitochondrial signalling.

The role of prophylactic cholecystectomy during splenectomy in children with hereditary spherocytosis.

BACKGROUND/PURPOSE: Hereditary spherocytosis is an autosomal dominant disorder associated with an intrinsic defect in the red blood cell membrane often necessitating splenectomy to prevent sequestration of spherocytes. When cholelithiasis is present, these patients undergo cholecystectomy at the same surgical setting as splenectomy. After splenectomy alone, it is uncertain whether the amount of hemolysis is adequately decreased to prevent subsequent gallstone formation. This study set out to evaluate the frequency in which symptomatic cholelithiasis subsequently develops in children treated by splenectomy alone. METHODS: All patients less than 18 years old with hereditary spherocytosis who underwent splenectomy without cholecystectomy at our institution during the past 27 years were included in this study. A retrospective chart review and telephonic patient follow-up was performed. Gallstones were excluded in these patients either by preoperative ultrasound scan, or by intraoperative palpation of the gallbladder. The main study outcomes of this group included documented cases of cholelithiasis, subsequent need for cholecystectomy secondary to cholelithiasis, and questionnaire to determine the incidence of "subclinical" cholelithiasis (not reported to a physician). RESULTS: Twenty-three subjects were identified who met the inclusion criteria. Complete follow-up data were obtained for 17 of these patients (74%). The mean age at splenectomy was 6.6 +/- 0.69 years, and the mean follow-up was 15.65 +/- 2.03 years (median, 18 years). None of the patients in this series subsequently have undergone cholecystectomy, nor have any had either clinical or subclinical evidence of cholelithiasis since splenectomy. CONCLUSION: Prophylactic cholecystectomy at the time of splenectomy is not indicated in patients with hereditary spherocytosis who do not have gallstones.

Glucocorticoids potently block tumour necrosis factor-alpha- and lipopolysaccharide-induced apoptotic cell death in bovine glomerular endothelial cells upstream of caspase 3 activation.

1. Endothelial cell damage in glomeruli and kidney arterioles appears to play a pivotal role in glomerular inflammatory diseases. Glomerular endothelial cells, a specialized microvascular cell type involved in the regulation of glomerular ultrafiltration, die by apoptosis in response to tumour necrosis factor-alpha (TNF-alpha), TNF-alpha/basic fibroblast growth factor (bFGF), TNF-alpha/cycloheximide, and bacterial lipopolysaccharide (LPS). Apoptotic cell death is characterized by extensive DNA cleavage, DNA ladder formation, and characteristic morphological alterations. 2. In search for apoptosis-preventing signals, we identified glucocorticoids as potent death preventing factors. Co-treatment of cells with 10 nM dexamethasone and TNF-alpha, TNF-alpha/bFGF, TNF-alpha/cycloheximide, or LPS blocked roughly 90% of apoptotic cell death in glomerular endothelial cells. 3. Similarly to dexamethasone (TNF-alpha- and LPS-induced apoptosis are prevented with IC50 values of 0.8 and 0.9 nM, respectively), other synthetic and natural forms of glucocorticoids, such as fluocinolone, prednisolone, hydrocortisone, and corticosterone potently inhibited cell death with IC50 values of 0.2, 6, 50 and 1000 nM, for TNF-alpha and 0.7, 8, 100 and 500 nM for LPS, respectively. 4. Apart from glucocorticoids, mineralocorticoids such as aldosterone also blocked TNF-alpha/LPS-induced apoptosis (IC50 approximately 500 nM for TNF-alpha and approximately 500 nM for LPS), whereas sex hormones, i. e. beta-estradiol and testosterone remained without effect. 5. The protective effect of glucocorticoids (and mineralocorticoids) required glucocorticoid receptor binding as it could be antagonized by the glucocorticoid receptor antagonist RU-486. Concerning TNF-alpha and LPS signal transduction, we found that dexamethasone efficiently prevented TNF-alpha- and LPS-induced activation of caspase-3-like proteases. Therefore, we postulate inhibitory mechanisms upstream of terminal death pathways.

Biosecurity in poultry production: where are we and where do we go?

An overview is given about the importance of biosecurity in the poultry industry, and a comparison is made with other systems of disease control such as vaccination and medication. Different measures considered to be important in bio-security are reviewed and some expectations for the future are given. Furthermore, some attention is paid to the animal welfare aspects.

The contributions of disease activity, sleep patterns, and depression to fatigue in systemic lupus erythematosus. A proposed model.

OBJECTIVE: This study describes lupus fatigue multidimensionally and introduces a multivariate model: Sleep problems and depression, through reciprocal effects on each other, act as mediators through which lupus disease activity increases fatigue. METHODS: Self-reported sleep patterns, depression, and fatigue were assessed in 48 women with systemic lupus erythematosus (SLE) and 27 women from the general population. Rheumatologists rated current lupus disease activity. RESULTS: The SLE group reported greater overall fatigue than did the controls. Temporal and affective dimensions of fatigue were more differentiating than sensory or severity dimensions. The SLE group also reported longer sleep latency and total sleep time, but not higher depression. Using 2-stage regression, a form of structural equation modeling, the proposed lupus fatigue model was supported. CONCLUSION: These preliminary results describe fatigue as a multidimensional phenomenon arising out of several contributing factors. They suggest that fatigue treatment strategies should address mediating processes such as sleep and depression, in addition to disease activity.

Role of cytoplasmic domain of the Na+/H+ exchanger in hormonal activation.

The growth factor-activated Na+/H+ exchanger is regulated by numerous stimuli, including polypeptide hormones, phorbol esters, cell acidity, and cell shrinkage. To determine whether this regulation occurs at a common site on the cytoplasmic domain of the Na+/H+ exchanger, we microinjected polyclonal antibodies (RP1-c28) to the C-terminal 157 amino acids of the molecule and measured cell pH changes after application of a variety of stimuli known to activate the Na+/H+ exchanger. Microinjection of approximately 10 fg of RP1-c28 antibody, but not control IgG, into single cultured fibroblasts blocked subsequent activation of the exchanger by both endothelin and alpha-thrombin. In contrast, microinjected RP1-c28 did not prevent activation of Na+/H+ exchange by phorbol esters, consistent with the observation that both endothelin-1 and alpha-thrombin retained the ability to activate exchange activity in protein kinase C-depleted cells. Finally, activation of Na+/H+ exchange by both cell acidity and osmotic shrinkage was also unaffected by microinjected RP1-c28 antibody. These data indicate that activation of Na+/H+ exchange by endothelin-1 and alpha-thrombin is mechanistically distinct both from activation by protein kinase C and activation by physical factors and probably occurs at a separate site on the exchanger molecule.

Cloning and functional expression of a vascular smooth muscle endothelin 1 receptor.

By screening a cDNA library derived from the A10 rat vascular smooth muscle cell line for functional expression in COS cells, we have isolated a high-affinity receptor for endothelin 1 (Kd = 476 pM) and endothelin 2. The affinity of the cloned endothelin receptor for endothelin 3 is greater than 100 times less in A10 cells and in a CHO cell line stably transformed by the endothelin receptor cDNA. The 426-amino acid receptor polypeptide has seven putative hydrophobic transmembrane domains and is presumed to be a member of the family of guanine nucleotide-binding regulatory (G) protein-coupled receptors. Microinjection of in vitro transcripts of the cloned cDNA into CHO cells confers a transient increase in intracellular calcium in response to endothelin 1, indicating that the receptor is functional and couples to the appropriate G protein(s). RNA analysis reveals high expression in rat lung and heart, tissues known to exhibit binding to iodinated endothelin 1.

The effect of serologically defined major histocompatibility complex haplotypes on Marek's disease resistance in commercially bred White Leghorn chickens.

In commercial pure white leghorn lines, A, B, and C, the effects on resistance against a virulent strain of Marek's disease virus were assessed for B19 and B21 haplotypes of the chicken major histocompatibility complex. B haplotypes were identified by direct hemagglutination using alloantisera raised against erythrocyte antigens. In homozygous B21 female chicks from lines A and B, mortality upon challenge with virus was 16% and 9%, respectively; in B19 chicks, mortality was 42% and 60%, respectively. Intermediate mortality was observed in heterozygous B19/B21 birds. When line A and B hens were crossed with B15/B15 or B5/B19 cocks from line C, differences between B19 and B21 were significant only in the progeny from B5/B19 sires. Therefore, it was concluded that selection for major histocompatibility complex-associated disease resistance markers may be useful only when B haplotypes complement each other in commercial line crosses and when interactions with genetic background do not severely obscure the differential haplotype effects, as are observed within pure lines.

Activation of protein kinase C triggers premature compaction in the four-cell stage mouse embryo.

During mouse preimplantation development, the cells of the mouse embryo undergo a progressive subcellular reorganization at compaction, which eventually results in the formation of two distinct cell types. We have investigated the effect that activators of the Ca2(+)-phospholipid-dependent protein kinase (PKC) have on mouse compaction. Phorbol ester activation of PKC caused premature compaction of four-cell embryos within a few minutes of addition followed by a prolonged decompaction phase after 1 hr. This response was dose-dependent to concentrations as low as 250 pg/ml. Diacylglycerides also caused compaction; however, it was more sustained than with phorbol esters and was not followed by a phase of decompaction. Inhibition of PKC with sphingosine blocks induced compaction in a dose-dependent manner and also blocks normal compaction of eight-cell embryos. A monoclonal antibody to the cell adhesion molecule, E-cadherin, which mediates mouse embryo compaction, completely blocks compaction induced by these activators of PKC. Indirect immunofluorescence with a monoclonal antibody to E-cadherin indicates that PKC activation causes a rapid shift in the localization of this cell adhesion molecule, which coincides with the observed compaction. These results suggest that PKC plays a role in the initiation of compaction through its effect either directly or indirectly on E-cadherin.

Octaploid mouse embryos produced by electrofusion polarize and cavitate at the same time as normal embryos.

We created enlarged octaploid mouse blastomeres by subjecting four-cell embryos to a large (greater than 2,000 V/cm) dc field of brief duration (10 microseconds). This electrofusion pulse caused three to four of the blastomeres to fuse in 60% of the embryos tested. Modifications of fusion chamber and medium enabled fusion of up to 20 embryos per pulse, greatly increasing the yield for this fusion method. The effectiveness of the electrofusion pulse depended upon such parameters as embryonic cell cycle time and the pH and temperature of the electrofusion medium. There was no discernable lag in the onset of the third cleavage division or the time of cavitation in fused blastomeres. These fused blastomeres also underwent polarization of their apical surfaces at the same time as controls in spite of their increased cell size. These results suggest that octaploid mouse blastomeres created via electrofusion divide normally through the blastocyst stage and polarize at the same time and in the same sequence as smaller control blastomeres. This suggests that the mechanisms underlying cell division, cavitation, and cortical polarization are not affected by changes in cellular size or ploidy.

Fate of the inner cell mass in mouse embryos as studied by microinjection of lineage tracers.

We microinjected horseradish peroxidase and rhodamine-conjugated dextran into single inner cell mass (ICM) cells of preimplantation mouse embryos to study their fate in culture. Simultaneous iontophoresis of both lineage markers allowed immediate localization of the injected cell by epifluorescence, followed by microdrop culture of individual embryos. After 24 hr in culture, labeled descendants were found in the polar trophectoderm, ICM, and parietal endoderm, providing direct evidence that the ICM contributes descendants to the trophectoderm and the endoderm in the intact mouse embryo. Our results substantiate the totipotency of the ICM during the expanding blastocyst stage and further demonstrate that the ICM is a stem cell population from which cells are recruited into these tissue lineages during growth of the blastocyst.

General method validation guidelines for pharmaceutical samples.

Method validation guidelines, which provide an organizational structure for the design and evaluation of a validation procedure, are presented for a wide range of pharmaceutical applications. The validation guidelines are based on the analyte concentration/sample matrix combination to which the method will be applied. These guidelines include the selection of appropriate validation parameters, design considerations for evaluation, and a discussion of acceptance guidelines for the determination of acceptable method performance. A set of tables is included which illustrates the selection and testing procedure and tailors the entire validation process to the specific characteristics of the determination to be made.
