ABSTRACT

Living with wildfires in an era of climate change requires adaptation and weaving together many forms of knowledge. Empirical evidence of knowledge co-production in wildfire management is lacking in Mediterranean European areas. We explored how local ecological knowledge can be leveraged to reduce wildfire risk through an adaptation pathways process in the Montseny massif and wider Tordera River watershed of Catalonia, Spain: an area stewarded through forestry and agriculture, tourism, nature conservation, and fire management. We combined different methods (e.g., a timeline and Three Horizons framework) throughout three workshops with agents of change to co-create adaptation pathways to reduce wildfire risk, integrating a historical perspective of the landscape while envisioning desirable futures. Our results showed that local ecological knowledge and other soft adaptation strategies contribute to innovative sustainable development initiatives that can also mitigate wildfire risk. The adaptation pathways approach holds much potential to inform local policies and support wildfire-based community initiatives in diverse contexts.

ABSTRACT

Indigenous cultural fire practitioners proactively revitalise their stewardship/custodianship of their traditional territories to generate diverse social, cultural, economic, self-determination, and ecological benefits. Government, researchers, and natural resource managers can overcome ongoing colonial legacies by enabling Indigenous leadership, providing ongoing investment and removing imposed barriers that restrict cultural fire practices.

ABSTRACT

Wood-inhabiting fungi (WIF), such as polypores, are extremely species-rich and play vital roles in the functioning of forest ecosystems as decomposers. Despite the importance of polypores, our knowledge of the diversity and distribution of these fungi is still poor in general and especially for West Africa. To advance our knowledge we here summarise results from field collections between 2017 and 2021 and present (i) a taxonomic overview, (ii) phylogenetic placements and (iii) an illustrated catalogue of wood-inhabiting polypore fungi with colour pictures. During the field sampling campaigns, we collected 647 specimens. Based on morphological characteristics and molecular barcode data, 76 polypore species belonging to six orders, 15 families and 39 genera were identified. Of the 76 species, 30 are new to the West Africa, 69 new to Benin, and two new combinations Fuscoporia beninensis and Megasporia minuta are proposed. With this summary, we provide new data for further research. Citation: Olou BA, Langer E, Ryvarden L, Krah F-S, Hounwanou GB, Piepenbring M, Yorou NS (2023).

ABSTRACT

During normal tumor growth and in response to some therapies, tumor cells experience acute or chronic deprivation of nutrients and oxygen and induce tumor vascularization. While this occurs predominately through sprouting angiogenesis, tumor cells have also been shown to directly contribute to vessel formation through vascular mimicry (VM) and/or endothelial transdifferentiation. The extrinsic and intrinsic mechanisms underlying tumor cell adoption of endothelial phenotypes, however, are not well understood. Here we show that serum withdrawal induces mesenchymal breast cancer cells to undergo VM and that knockdown of the epithelial-to-mesenchymal transition (EMT) regulator, Zinc finger E-box binding homeobox 1 (ZEB1), or overexpression of the ZEB1-repressed microRNAs (miRNAs), miR-200c, miR-183, miR-96 and miR-182 inhibits this process. We find that secreted proteins Fibronectin 1 (FN1) and serine protease inhibitor (serpin) family E member 2 (SERPINE2) are essential for VM in this system. These secreted factors are upregulated in mesenchymal cells in response to serum withdrawal, and overexpression of VM-inhibiting miRNAs abrogates this upregulation. Intriguingly, the receptors for these secreted proteins, low-density lipoprotein receptor-related protein 1 (LRP1) and Integrin beta 1 (ITGB1), are also targets of the VM-inhibiting miRNAs, suggesting that autocrine signaling stimulating VM is regulated by ZEB1-repressed miRNA clusters. Together, these data provide mechanistic insight into the regulation of VM and suggest that miRNAs repressed during EMT, in addition to suppressing migratory and stem-like properties of tumor cells, also inhibit endothelial phenotypes of breast cancer cells adopted in response to a nutrient-deficient microenvironment.

ABSTRACT

Colletotrichum cliviae is a fungal species reported both as pathogen and endophyte with broad geographical distribution. Some purported isolates of this species have been assigned to different taxa, including Colletotrichum aracearum, Colletotrichum orchidearum and Colletotrichum. sichuanensis, for which a preliminary analysis of extensive multilocus (ACT, GAPDH, ITS, TUB2) data in this study revealed high sequence similarity with C. cliviae. We further reassessed the species delineation by using the coalescent method of the generalized mixed Yule-coalescent (GMYC) and Poisson Tree Processes (PTP). Single and multilocus gene trees strongly supported a C. cliviae s. lat. clade including the four species. This clade unfolded eight subclades grouped into three distinct lineages, but no monophyly of any of the four species. GMYC and PTP analyses confidently supported the evolutionary independence of these lineages. C. sichuanensis and C. cliviae, except one isolate, formed the largest lineage. The second lineage was made up of isolates named C. aracearum and some of C. orchidearum sharing the haplotype and the third lineage accommodated two isolates named C. cliviae and C. orchidearum. This finding suggests the synonymization of C. sichuanensis with C. cliviae whereas the taxonomic status of C. aracearum and C. orchidearum still needs clarification. This study lays great stress upon the use of comprehensive data for sequence-based characterisation of species in the C. cliviae s. lat. It also presents the first report of C. cliviae in tropical Africa and on citrus host.

ABSTRACT

Synovial sarcomas are aggressive soft-tissue malignancies that express chromosomal translocation-generated fusion genes, SS18-SSX1 or SS18-SSX2 in most cases. Here, we report a mouse sarcoma model expressing SS18-SSX1, complementing our prior model expressing SS18-SSX2. Exome sequencing identified no recurrent secondary mutations in tumors of either genotype. Most of the few mutations identified in single tumors were present in genes that were minimally or not expressed in any of the tumors. Chromosome 6, either entirely or around the fusion gene expression locus, demonstrated a copy number gain in a majority of tumors of both genotypes. Thus, by fusion oncogene coding sequence alone, SS18-SSX1 and SS18-SSX2 can each drive comparable synovial sarcomagenesis, independent from other genetic drivers. SS18-SSX1 and SS18-SSX2 tumor transcriptomes demonstrated very few consistent differences overall. In direct tumorigenesis comparisons, SS18-SSX2 was slightly more sarcomagenic than SS18-SSX1, but equivalent in its generation of biphasic histologic features. Meta-analysis of human synovial sarcoma patient series identified two tumor-gentoype-phenotype correlations that were not modeled by the mice, namely a scarcity of male hosts and biphasic histologic features among SS18-SSX2 tumors. Re-analysis of human SS18-SSX1 and SS18-SSX2 tumor transcriptomes demonstrated very few consistent differences, but highlighted increased native SSX2 expression in SS18-SSX1 tumors. This suggests that the translocated locus may drive genotype-phenotype differences more than the coding sequence of the fusion gene created. Two possible roles for native SSX2 in synovial sarcomagenesis are explored. Thus, even specific partial failures of mouse genetic modeling can be instructive to human tumor biology.

ABSTRACT

Biosolids management has been largely overlooked as an issue for environmental co-management, collaborative learning and public participation. This paper summarises four research projects on facilitating community involvement in biosolids management in New Zealand. The authors situate these studies both in relation to the New Zealand institutional and policy context for the management of biosolids and in relation to the themes of public participation and social learning in the literature on community involvement in environmental management. From the studies it can be concluded that: the incorporation of the knowledge and views of Maori is important from both public-participation and social-learning perspectives; both public-participation and social-learning approaches must consider the role of issue-definition in relation to willingness to participate; democratic accountability remains a challenge for both approaches; and locating biosolids management within an integrated water-and-wastewater or sustainable waste-management strategy may facilitate wider community participation as well as better-coordinated decision-making.

ABSTRACT

In respect to the actual discussion of new anticoagulants in secondary haemostasis, we will give a short review on established oral anticoagulation with vitamin K antagonists and parenteral anticoagulation by use of heparin. The different coumarin derivatives phenprocoumon, warfarin, and acenocoumarol are compared concerning to the management and influence of pharmacogenetic and pharmacokinetic factors. Studies to improve the safety of oral anticoagulation by vitamin K supplementation will be briefly discussed. The therapy with heparins include until now some problems of dose-response control. It is necessary to pay attention to contra-indications even for well known anticoagulants. Examples for that will be given.

ABSTRACT

Strategies for beneficial use of biosolids in New Zealand and elsewhere are currently focused primarily on land application. The long-term success of these and other strategies is dependent not only on technical factors, but also on their environmental, economic, social and cultural sustainability. This paper briefly reviews the situation with respect to biosolids management in New Zealand, where land application is not yet widespread; the rise in public opposition to land application in the United States; and the biosolids industry's approach to public engagement. We argue that, at least until recently, the industry has misinterpreted the nature and meaning of public opposition and thus substituted public relations for public engagement. We argue that genuine public engagement is necessary and that its purpose cannot be to gain public acceptance for an already-decided-upon strategy. It therefore calls for humility among biosolids managers, including a willingness to open up the framing of 'the problem', to acknowledge areas of uncertainty, and to recognise the role of values in 'technical' decision-making. We then present and analyse an example of the use of the scenario workshop process for public participation in biosolids management policy in Christchurch, New Zealand, and conclude that scenario workshops and related methods represent an opportunity to enhance sustainable waste management when certain conditions are met.

ABSTRACT

BACKGROUND: This study was designed to evaluate prognostic parameters for respiratory failure after major oropharyngeal resections in head and neck cancer surgery, focusing on a score system to identify patients requiring an elective tracheotomy and to avoid tracheotomy under emergency conditions. METHODS: One hundred and fifty-two out of 928 patients with oropharyngeal cancers, treated between January 1993 and June 2000 at our hospital, fulfilled the inclusion criteria for a retrospective analysis. This collective underwent tumour resection in different regions of the oropharynx combined with bony resection of the mandible and neck dissection without primary tracheotomy. The reconstruction was accomplished using radial forearm flaps (n1 = 59) or local flaps (n2 = 93). These two groups were subdivided into patients treated post-operatively by tracheotomy due to respiratory failure (n1 = 26; n2 = 12) and those without such treatment (n1 = 33; n2 = 81). The database comprising tumour localization and size, staging, general medical condition, smoking and alcohol consumption was evaluated by logistic regression. RESULTS: We developed a score system which predicts the likelihood of post-operative respiratory failure. For indication of tracheotomy, tumour size and localization, multimorbidity, alcohol consumption and pathologic chest X-ray findings were identified as significant parameters with different weightings. The predictive value for tracheotomy (yes/no) using the score system was 96.7% for the total collective. CONCLUSION: The decision on whether or not an elective tracheotomy in major head and neck tumour surgery is necessary can be facilitated using this score system which is based on objective facts. It may reduce post-operative complications and contribute to safer treatment.

ABSTRACT

Cell culture and animal models have played an essential role in the research of new principles of therapy. Many methods for the individualized testing of therapy sensitivity and resistance have been developed, for example, the clonogenic assay. Presently, the ATP-TCA is commercially available as a testing kit. This review gives an overview of the tumor samples that were tested in the oncologic laboratory in the Department of Obstetrics and Gynecology, Munich Grosshadern between 1993 and 2001. All target parameters show a clear trend in favor of sequential, dose-intensified Epirubicin/Paclitaxel therapy. If this trend remains valid for the total number of patients, a significant impact of this new principle of therapy can be expected. By individualized planning of therapy with ATP-TCA testing, therapy in the individual patient could already be performed by the examination of sensitivity in the preoperative biopsy specimen.

ABSTRACT

The purpose of this study was to analyze the drug interactions of paclitaxel (PTX) with epirubicin (EPI), carboplatin (CBDCA), gemcitabine (GEM) and vinorelbine (VIN) in human breast cancer cells and compare the cytotoxic activity of each drug combination in primary breast cancer samples. These experiments were intended to identify the most active agents in combination with PTX, and to provide a preclinical rational for future clinical investigations in breast cancer. Multiple drug effect/combination index (CI) isobologram analysis was applied to combinations of PTX with either CBDCA, EPI, GEM or VIN in MCF-7, MDA-MB-231 and SK-BR-3 human breast cancer cell lines. Drug concentrations were limited to the ranges achievable in humans in vivo, and the drugs were applied simultaneously at fixed molar ratios for each drug combination. Interactions were assessed at multiple effect levels (IC10-IC90). Additionally, the cytotoxic activity of these combinations was assessed in tumor samples of 50 primary breast cancer patients, utilizing the ATP-tumorchemosensitivity assay (ATP-TCA). Drug interactions were shown to be strongly dose-related in the human breast cancer cell lines investigated. At clinically relevant concentrations, CBDCA/PTX demonstrated synergistic (MCF-7) or additive (MDA-MB-231, SK-BR-3) interactions, and EPI/PTX showed additive (SK-BR-3, MCF-7) and antagonistic (MDA-MB-231) interactions. GEM/PTX and VIN/PTX, however, demonstrated antagonism over multiple dose effect levels at clinically relevant drug concentrations in all three cell lines tested. At plasma peak concentrations, EPI/PTX, CBDCA/PTX, GEM/PTX and VIN/PTX achieved > or = 90% tumor growth inhibition in 93, 86, 63 and 50%, respectively, of primary breast cancer samples investigated with the ATP-TCA. Cumulative dose-response plots of primary breast cancer tumor cells responding in vitro with > or = 90% growth inhibition showed a strong dose dependence for both EPI/PTX and CBDCA/PTX. In conclusion, the current data indicate favorable drug interactions for CBDCA/PTX at clinically relevant drug concentrations in breast cancer cells, and demonstrate superior in vitro cytotoxicity of EPI/PTX and CBDCA/PTX compared to GEM/PTX and VIN/PTX in primary breast cancer cultures.

ABSTRACT

OBJECTIVE: To compare mortality following isolation of influenza A to mortality following isolation of other respiratory viruses in a nursing home. SETTING: The Wisconsin Veterans Home, a 688-bed skilled nursing facility for veterans and their spouses. PARTICIPANTS: All residents with respiratory viral isolates obtained between 1988 and 1999. DESIGN: Thirty-day mortality was determined following each culture-proven illness. RESULTS: Thirty-day mortality following isolation of viral respiratory pathogens was 4.7% (15/322) for influenza A; 5.4% (7/129) for influenza B; 6.1% (3/49) for parainfluenza type 1; 0% (0/26) for parainfluenza types 2, 3, and 4; 0% (0/26) for respiratory syncytial virus (RSV); and 1.6% (1/61) for rhinovirus. CONCLUSIONS: Mortality following isolation of certain other respiratory viruses may be comparable to that following influenza A (although influenza A mortality might be higher without vaccination and antiviral agents). The use of uniform secretion precautions for all viral respiratory illness deserves consideration in nursing homes.

ABSTRACT

OBJECTIVE: To report the number and timing of influenza A isolates, as well as overlapping respiratory viruses. Co-circulating respiratory viruses may obscure the determination of influenza activity. DESIGN: Prospective clinical surveillance for the new onset of respiratory illness followed by viral cultures during seven separate influenza seasons. SETTING: The Wisconsin Veterans Home, a skilled nursing facility for veterans and their spouses. RESULTS: Influenza A isolates were encountered in greater numbers than non-influenza A isolates during three seasons. Seasonal variability is striking. In December 1992, we identified a large outbreak of respiratory illness. Influenza type B was cultured from 102 residents. In December 1995, influenza A was cultured from 285 people in Wisconsin. At that time, we identified outbreaks of respiratory illness in two of our four buildings. Based on statewide data, we suspected an influenza outbreak; however, 26 isolates of parainfluenza virus type 1 were cultured with no influenza. The potential importance of culturing at the end of the season was demonstrated in 1991-1992 when an outbreak of respiratory syncytial virus (RSV) overlapped and extended beyond influenza A activity. CONCLUSIONS: When interpreting new clinical respiratory illnesses as a basis for declaring an outbreak of influenza A, clinicians should realize that co-circulating respiratory viruses can account for clinical illnesses. Clinicians might utilize healthcare dollars efficiently by performing cultures to focus the timing of influenza A chemoprophylaxis. Cultures could be performed when clinical outbreak criteria are approached to confirm an outbreak. Culturing of new respiratory illness could begin again before the anticipated discontinuation of prophylaxis (approximately 2 weeks).

ABSTRACT

Homobasidiomycete fungi display many complex fruiting body morphologies, including mushrooms and puffballs, but their anatomical simplicity has confounded efforts to understand the evolution of these forms. We performed a comprehensive phylogenetic analysis of homobasidiomycetes, using sequences from nuclear and mitochondrial ribosomal DNA, with an emphasis on understanding evolutionary relationships of gilled mushrooms and puffballs. Parsimony-based optimization of character states on our phylogenetic trees suggested that strikingly similar gilled mushrooms evolved at least six times, from morphologically diverse precursors. Approximately 87% of gilled mushrooms are in a single lineage, which we call the "euagarics." Recently discovered 90 million-year-old fossil mushrooms are probably euagarics, suggesting that (i) the origin of this clade must have occurred no later than the mid-Cretaceous and (ii) the gilled mushroom morphology has been maintained in certain lineages for tens of millions of years. Puffballs and other forms with enclosed spore-bearing structures (Gasteromycetes) evolved at least four times. Derivation of Gasteromycetes from forms with exposed spore-bearing structures (Hymenomycetes) is correlated with repeated loss of forcible spore discharge (ballistospory). Diverse fruiting body forms and spore dispersal mechanisms have evolved among Gasteromycetes. Nevertheless, it appears that Hymenomycetes have never been secondarily derived from Gasteromycetes, which suggests that the loss of ballistospory has constrained evolution in these lineages.

ABSTRACT

Using figure drawings, perception of body shape was evaluated by underweight, average, and overweight men and women. Body-shape dissatisfaction was greatest for 60 overweight women, and about the same in 151 average weight women as it was for 102 overweight men. Average weight men (n = 107) and underweight women (n = 31) were fairly satisfied with their current shapes. Both men and women had distorted views of the shape the opposite sex found most attractive. Women guessed that men would prefer a thinner shape than they actually did, and men guessed that women would prefer a larger shape than they actually did. The distortion was larger for men as their own size increased but not for women.

ABSTRACT

This study explores whether negative stereotypes about aging contribute to memory loss in old age. The research participants consisted of old and young Chinese hearing, American Deaf, and American hearing individuals. Members of the mainland Chinese and the American Deaf cultures were recruited on the basis of the belief that they would be less likely than hearing Americans to be exposed to and accept negative stereotypes about aging. The expected results were (a) an interaction in which the 3 groups of younger Ss would perform similarly on the memory tasks, whereas the older Deaf and older Chinese participants would outperform the older American hearing group and (b) a positive correlation between view toward aging and memory performance among the old Ss. The data supported both hypotheses. The results suggest that cultural beliefs about aging play a role in determining the degree of memory loss people experience in old age.

ABSTRACT

OBJECTIVE: To identify risk factors for bacteriuria in a selected group of institutionalized men. METHODS: A total of 99 men, mean age seventy-one years, range forty-eight to one hundred four years, living in a nursing home were evaluated for diagnoses of benign prostatic hyperplasia (BPH) and diabetes mellitus (DM), symptoms of bladder outlet obstruction, and postvoid residual urine volume (PVR). At the time of evaluation urine cultures were performed for all subjects. Urinalyses had been performed in all men within the two years prior to initiation of the study. Residents unable to give informed consent, with a history of cancer of the prostate or bladder, previous urethral or prostate surgery, or inability to void in the standing position were excluded. RESULTS: Prior to or during the study 30 residents had bacteriuria, which was not correlated with age, PVR, previous diagnoses of BPH or DM, or with obstructive or irritative urinary symptoms consistent with bladder outlet obstruction. CONCLUSIONS: Competent, institutionalized residents with higher functional levels meeting the inclusion criteria were not at a high risk of bacteriuria. The concept that increased PVR per se predisposes to bacteriuria cannot be substantiated.

ABSTRACT

OBJECTIVE: To compare the efficacy of an influenza hemagglutinin-diphtheria toxoid conjugate vaccine with the commercially available influenza hemagglutinin-subunit vaccine in preventing influenza in older adults living in a nursing home. DESIGN: A prospective, randomized, double-blind vaccine trial with 5 months of follow-up after vaccination. SETTING: Fourteen Wisconsin nursing homes. PARTICIPANTS: Nursing home residents at least 65 years old who were able to give informed consent and were free of malignancy and not receiving immunosuppressive therapy. INTERVENTIONS: Participants received, by intramuscular injection, 0.5 mL of a trivalent influenza vaccine containing 15 micrograms each of A/Leningrad/360/86 (H3N2), A/Taiwan/1/86 (H1N1), and B/Ann Arbor/1/86 (HA) or 0.5 mL of an influenza vaccine containing the same antigens conjugated to diphtheria toxoid (HA-D). MEASUREMENTS: Blood was obtained pre- and 1 month post-vaccination to assess for any vaccine-induced antibody titer change. Clinical surveillance for respiratory illness was performed twice weekly for 5 months. A record was kept of all signs and symptoms of new respiratory illness, and a viral culture and acute and convalescent sera were obtained. RESULTS: 204 participants received HA and 204 received HA-D. Both groups had similar baseline antibody levels to all influenza antigens. HA-D recipients seroconverted more frequently based on serum neutralizing activity (P < 0.05), had a greater increase in geometric mean titer (GMT), and sustained the increase in antibody titer longer than HA recipients. Vaccine hemagglutinin recall was greater in a subset of HA-D recipients as measured by lymphocyte proliferative assays (P < 0.05). During an outbreak of influenza A (H3N2 A/Shanghai/11/87-like and A/Victoria/7/87-like), fewer HA-D (29/195) than HA (43/204) recipients had laboratory-confirmed infection (P = 0.053), and, of these, fewer HA-D-treated subjects had lower respiratory tract involvement (5/29 HA-D and 17/43 HA) (P = 0.022). CONCLUSIONS: HA-D was more immunogenic in institutionalized elderly recipients and produced greater protection from influenza infection. Superior protection may be due to HA-D's ability to stimulate and recruit antigen-presenting cells, thus enabling the recipient to achieve and maintain functional antibody titers.
