Discrimination against suspected Islamic terrorists: Nationality, right-wing authoritarianism, and perceived threat as predictors of support for torture.

This research investigates discrimination against suspected Islamic terrorists based on tolerance for the use of torture. This research is justified by the need to identify how intergroup and ideological factors combine to express discrimination. Two experimental studies were conducted with a between-subjects design. Study 1 (N = 282) analysed the terrorist threat against the ingroup and the nationality of torturers with respect to support for torture against suspected Islamic terrorists. Study 2 (N = 165) analysed the interaction among terrorist threat against the ingroup and perceived threat (realistic and symbolic) as moderators in the relationship between RWA and discrimination. Study 1 indicated that support for torture was greater when the victims of terrorist acts and the torturers belonged to the ingroup. Study 2 indicated that the perceived threat encourages support for the use of torture, regardless of the levels of RWA. Taken together, these results elucidate the psychosocial processes that are present in the hostility towards social minorities from predominantly Muslim countries and in the strengthening of xenophobic political positions.

Context, intersectionality, and resilience: Moving toward a more holistic study of bilingualism in cognitive science.

OBJECTIVE: Bilingual experiences are diverse, vibrant, and multidimensional. Yet, prior research has often homogenized bilingualism and based outcomes upon monolingual norms. Framing monolinguals as the norm distorts the reality of bilingual experiences. To promote a more diverse and inclusive study of bilingualism, we propose a theoretical and methodological paradigm shift. Bilinguals exist in different networks, cultural contexts, and individual and societal settings, all of which may lead to differential cognitive and linguistic outcomes that will be lost if left unexamined. Bilingual interactional contexts occur within extensive environmental and ecological systems, and may lead to different outcomes based on experiences within these systems. We seek to recognize these interactional contexts and how, as researchers, we can strive to better understand the complexities of bilingual populations. METHOD: We propose incorporating more diverse theoretical frameworks-including raciolinguistics, an intersectional resiliency perspective, and an ecological approach-so that researchers can begin to think about how bilingual experiences are shaped before study participants enter the lab. Included also are methodological considerations that will improve our understanding of bilinguals' intersectional experiences. We offer suggestions for becoming more diverse and inclusive in our research. CONCLUSION: We encourage scientists to take a more holistic and nuanced approach to understanding how individual and contextual factors affect our study populations.

Antifungal susceptibility profile and molecular identification of Cyp51C mutations in clinical and environmental isolates of Aspergillus flavus from Argentina.

BACKGROUND: The emergence of azole resistance in non-fumigatus Aspergillus strains is on the raise. OBJECTIVES: To study the susceptibility profiles and the molecular mechanisms of azole resistance of environmental and clinical strains of Aspergillus flavus from Argentina. METHODS: Thirty-five A flavus isolates (18 from soybean seeds and chickpea seeds and 17 from the clinic) were analysed for amphotericin B and azole resistance using the standard microbroth dilution method according to CLSI M38-A2 guidelines. Sequencing analysis of the cyp51 genes was conducted in those isolates displaying high MICs values to itraconazole, voriconazole and/or posaconazole. RESULTS: Among the environmental isolates, 33.3% of them showed high MIC values for at least one triazole whereas 23.5% of the clinical isolates displayed high MIC values for amphotericin B. Point mutations in the Cyp51C gene were recorded in most environmental isolates with non-wild-type MIC values. CONCLUSIONS: Susceptibility differences among environmental A flavus isolates might suggest the possibility of native resistance to certain triazole antifungals used in the clinic. To the best of our knowledge, this is the first report of antifungal screening of environmental strains of A flavus in soybean seeds and chickpea seeds from Argentina that showed increased resistance to voriconazole and itraconazole in comparison to clinical strains.

[Optimization of variables in photodynamic antifungal assays against Candida species]. / Optimización de variables en ensayos de actividad antifúngica fotodinámica frente a especies de Candida.

Oral infections due to yeasts of the genus Candida are very common in patients with predisposing factors, such as physiological conditions or certain underlying diseases. Moreover, oral candidiasis can also evolve into disseminated forms. In this work, strains of the genus Candida were studied to establish the optimal radiation conditions for photosensitizing compounds, in a photodynamic antifungal therapy protocol. A total of 39 isolates were evaluated. The strains were exposed to twelve dyestuffs, eight radiation sources and three different exposure times. Orthotoluidine blue exhibited good photodynamic activity, in combination with exposure to a 20W reflector lamp LED (light-emitting diode) light for 60minutes. When considering the difficulties of using conventional antifungal drugs, the emergence of resistant strains, recurrences, and adverse reactions of certain commonly used drugs, the photodynamic antifungal therapy is a promising strategy for the treatment of localized infections.

[Scedosporium spp. osteomyelitis: A case report]. / Osteomielitis por Scedosporium spp., a propósito de un caso.

Scedosporium is a fungus that has a worldwide distribution, and which can be found in soil and contaminated water. It can rarely affect bone tissue and can do it either by direct inoculation or through trauma. We present here a case of a 54- year- old male patient with a diagnosis of chronic bacterial osteomyelitis due to an aquatic accident and exposed fracture of tibia-fibula of both members, which was treated with broad-spectrum antibiotics for 120 days. Eight months after the onset of the disease, Scedosporium spp. was isolated from the collection of one of the affected member, which was treated with voriconazole in combination with terbinafine.

Metabolic profiles of soybean roots during early stages of Fusarium tucumaniae infection.

Soybean germplasm exhibits various levels of resistance to Fusarium tucumaniae, the main causal agent of sudden death syndrome (SDS) of soybean in Argentina. In this study, two soybean genotypes, one susceptible (NA 4613) and one partially resistant (DM 4670) to SDS infection, were inoculated with F. tucumaniae. Disease symptoms were scored at 7, 10, 14, and 25 days post-inoculation (dpi). The greatest difference in the area under the disease progress curve (AUDPC) values among genotypes was observed at 25 dpi. In order to detect early metabolic markers that could potentially discriminate between susceptible and resistant genotypes, gas chromatography-mass spectrometry (GC-MS) analyses of root samples were performed. These analyses show higher levels of several amino acids and the polyamine cadaverine in the inoculated than in the uninoculated susceptible cultivar at 7 dpi. Principal component analysis (PCA) revealed that the metabolic profile of roots harvested at the earliest time points from the inoculated susceptible genotype was clearly differentiated from the rest of the samples. Furthermore, variables associated with the first principal component were mainly amino acids. Taken together, the results indicate that the pathogen induced the susceptible plant to accumulate amino acids in roots at early time points after infection, suggesting that GC-MS-based metabolomics could be used for the rapid characterization of cultivar response to SDS.

Genetic architecture and evolution of the mating type locus in fusaria that cause soybean sudden death syndrome and bean root rot.

Fusarium tucumaniae is the only known sexually reproducing species among the seven closely related fusaria that cause soybean sudden death syndrome (SDS) or bean root rot (BRR). In a previous study, laboratory mating of F. tucumaniae yielded recombinant ascospore progeny but required two mating-compatible strains, indicating that it is heterothallic. To assess the reproductive mode of the other SDS and BRR fusaria, and their potential for mating, whole-genome sequences of two SDS and one BRR pathogen were analyzed to characterize their mating type (MAT) loci. This bioinformatic approach identified a MAT1-1 idiomorph in F. virguliforme NRRL 22292 and MAT1-2 idiomorphs in F. tucumaniae NRRL 34546 and F. azukicola NRRL 54364. Alignments of the MAT loci were used to design PCR primers within the conserved regions of the flanking genes APN1 and SLA2, which enabled primer walking to obtain nearly complete sequences of the MAT region for six MAT1-1 and five MAT1-2 SDS/BRR fusaria. As expected, sequences of the highly divergent 4.7 kb MAT1-1 and 3.7 kb MAT1-2 idiomorphs were unalignable. However, sequences of the respective idiomorphs and those that flank MAT1-1 and MAT1-2 were highly conserved. In addition to three genes at MAT1-1 (MAT1-1-1, MAT1-1-2, MAT1-1-3) and two at MAT1-2 (MAT1-2-1, MAT1-2-3), the MAT loci of the SDS/BRR fusaria also include a putative gene predicted to encode for a 252 amino acid protein of unknown function. Alignments of the MAT1-1-3 and MAT1-2-1 sequences were used to design a multiplex PCR assay for the MAT loci. This assay was used to screen DNA from 439 SDS/BRR isolates, which revealed that each isolate possessed MAT1-1 or MAT1-2, consistent with heterothallism. Both idiomorphs were represented among isolates of F. azukicola, F. brasiliense, F. phaseoli and F. tucumaniae, whereas isolates of F. virguliforme and F. cuneirostrum were only MAT1-1 and F. crassistipitatum were only MAT1-2. Finally, nucleotide sequence data from the RPB1 and RPB2 genes were used to date the origin of the SDS/BRR group, which was estimated to have occurred about 0.75 Mya (95% HPD interval: 0.27, 1.68) in the mid-Pleistocene, long before the domestication of the common bean or soybean.

Exploring soybean cultivar susceptibility to sudden death syndrome: Insights into isoflavone responses and biocontrol potential.

Sudden Death Syndrome (SDS) caused by Fusarium tucumaniae is a significant threat to soybean production in Argentina. This study assessed the susceptibility of SY 3 × 7 and SPS 4 × 4 soybeans cultivars to F. tucumaniae and studied changes in root isoflavone levels after infection. Additionally, the biocontrol potential of plant-growth promoting rhizobacteria (PGPR) against SDS was also examined. Our results demonstrated that the SY 3 × 7 cultivar exhibited higher disease severity and total fresh weight loss than SPS 4 × 4. Both cultivars showed induction of daidzein, glycitein, and genistein in response to infection, with the partially resistant cultivar displaying significantly higher daidzein levels than the susceptible cultivar at 14 days post infection (dpi) (2.74 vs 2.17-fold), declining to a lesser extent at 23 dpi (0.94 vs 0.35-fold, respectively). However, daidzein was not able to inhibit F. tucumaniae growth in in vitro assays probably due to its conversion to an isoflavonoid phytoalexin which would ultimately be an effective fungal inhibitor. Furthermore, the PGPR bacterium Bacillus amyloliquefaciens BNM340 displayed antagonistic activity against F. tucumaniae and reduced SDS symptoms in infected plants. This study sheds light on the varying susceptibility of soybean cultivars to SDS, offers insights into isoflavone responses during infection, and demonstrates the potential of PGPR as a biocontrol strategy for SDS management, providing ways for disease control in soybean production.

Design, characterization, and in vitro evaluation of antifungal polymeric films.

The objective of the present paper was the development and the full characterization of antifungal films. Econazole nitrate (ECN) was loaded in a polymeric matrix formed by chitosan (CH) and carbopol 971NF (CB). Polyethylene glycol 400 and sorbitol were used as plasticizing agents. The mechanical properties of films were poorer when the drug was loaded, probably because crystals of ENC produces network outages and therefore reduces the polymeric interactions between the polymers. Polymers-ECN and CH-CB interactions were analyzed by Fourier-transform infrared spectroscopy (FTIR), thermal gravimetry analysis, and differential thermal analysis (DTA-TGA). ECN did not show structure alterations when loaded into the films. In scanning electron microphotographs and atomic force microscopy analysis, films prepared with CB showed an evident wrinkle pattern probably due to the strong interactions between the polymers, which were observed by FTIR and DTA-TGA. The in vitro activity of the formulations against Candida krusei and Candida parapsilosis was twice as greater as the commercial cream, probably as a result of the antifungal combination of the drug with the CH activity. All these results suggest that these polymeric films containing ECN are potential candidates in view of alternatives dosages forms for the treatment of the yeast assayed.

[Taxonomic study of clinic isolates of Trichophyton in Rosario, Argentina]. / Estudio taxonómico de aislamientos clínicos de Trichophyton en Rosario, Argentina.

Due to the pleomorphism and cultural variability displayed by species of the genus Trichophyton, the identification methods based solely on morphological features are usually insufficient for their classification. The goal of the present work was to test a set of phenotypic methods in order to identify fungal isolates that belong to the aforementioned genus. These methods were based on a molecular taxonomic technique used as standard. Clinical isolates (56) were used as samples along with 6 reference strains. Macro and micromorphological studies were performed as well as biochemical and physiological tests such as in vitro hair perforation, nutritional requirements in Trichophyton agar media, urease production and growth on bromocresol purple-milk. solids-glucose (BCP-MS-G) agar. Additionally, PCR fingerprinting using the (GACA)4 primer was employed. As a result of the PCR method, specific profiles were observed for Microsporum canis, Epidermophyton floccosum, Trichophyton rubrum and Trichophyton interdigitale. Identical profiles were obtained for Arthroderma benhamiae y Trichophyton erinacei. Of the total number of clinical isolates, 39 matched the T. rubrum profile while 13 corresponded to A. benhamiae and 4 to T. interdigitale. The most useful phenotypic test to differentiate between T. rubrum and T. mentagrophytes complex strains was alkalinization of the BCP-MS-G medium. Phenotypic tests did not allow differentiation among the T. mentagrophytes complex species. On the other hand, the molecular technique allowed characterization of T. rubrum isolates as well as of those observed in our study and included in the T. mentagrophytes complex: T. interdigitale and Trichophyton sp., the anamorph of A. benhamiae.

Effects of Posttraumatic Stress Disorder and Mental Disorders on the Labor Market Integration of Young Syrian Refugees.

Civil war experience in the Syrian home country, insecurity and critical life events during migration, or adverse events in the receiving country might affect refugees' mental health. This paper addresses the effects of psychological distress and mental disorders on refugees' labor market integration in Germany between 2016 and 2021. We employ survey data from about 2700 young Syrians, delivering information on individuals' experience of migration and arrival in Germany in 2016. The survey data were successfully merged with register data, delivering detailed information regarding individuals' process of labor market integration and employment status from 2016 to 2021. Overall, the labor market integration of young refugees improved remarkably over time. In 2021, about 69% of the study population was integrated in a wider sense, and 30% was employed in fulltime contracts in 2021. However, the results indicate long-lasting effects of PTSD and mental disorders on individuals' labor market integration, whilst individuals' characteristics related to migration and arrival lose relevance over time and hardly affect labor market integration around five years after arrival. High PTSD scores in 2016 indicate a significantly reduced full-time employment probability in 2021. Anxiety and depression show significant negative effects on individuals' labor market integration, but with a less severe impact compared to a PTSD diagnosis.

Morphological transparency and markedness matter in heritage speaker gender processing: an EEG study.

The present study investigated the qualitative nature of grammatical gender knowledge and processing in heritage speakers (HSs) of Spanish living in the United States. Forty-four adult Spanish HS bilinguals participated, completing a behavioral grammatical gender assignment task and a grammaticality judgment task (GJT) while their brain activity was recorded using electroencephalography (EEG). The EEG GJT task included grammatical and ungrammatical sentences with grammatical gender violations on inanimate nouns, where transparency of the morpho(phono)logical cue and markedness were manipulated. The results of this study revealed that grammatical gender violations elicited the typical P600 effect across all relevant conditions, indicating that the grammatical representations and processing of grammatical gender in HSs are qualitatively similar to those in Spanish-dominant native speakers. Given the experimental manipulation in this study, these findings also suggest that both morphological transparency and markedness play significant roles in how grammatical gender is processed. However, the results of this study differ from those reported in previous studies with Spanish-dominant native speakers, as the P600 effect found was accompanied by a biphasic N400 effect. This pattern of results is interpreted as further evidence that the bilingual experience of HSs modulates certain aspects of morphosyntactic processing, particularly conferring a greater reliance on morphology. Additionally, the results of this study highlight the importance of incorporating neurolinguistic online processing methods to better understand what underlies HS bilingual competence and processing outcomes.

Scedosporium boydii finding in an immunocompromised patient and review of the literature.

BACKGROUND: Scedosporiasis is an emerging mycosis that has gained importance in recent years due to its worldwide prevalence. It is caused by species of the Scedosporium apiospermum complex. These species can cause opportunistic infections in immunocompromised patients and, occasionally, in immunocompetent patients as well. The high intrinsic antifungal resistance make these infections difficult to manage. AIMS: The objective of this study was to interpret the mycological findings in a transplant patient, together with the images obtained in the radiological studies, in order to provide an early and effective antifungal therapy. METHODS: The mycological analysis of samples taken from a heart transplant patient with radiological images suggesting a fungal infection was performed. Computed tomography scan of the head and thorax showed space-occupying lesions in both the frontal lobe and cerebellum, and multiple pulmonary nodules. The nodules were punctured and the samples obtained were analyzed according to the procedures for mycological analysis. The identity of the isolates was confirmed by nucleotide sequencing. Eventually, the antifungal susceptibility was studied. RESULTS: The fungal isolates obtained, whose identity was confirmed by sequencing, belonged to the species Scedosporium boydii. Injured tissues were surgically removed and a treatment with amphotericin B and voriconazole-minimum inhibitory concentration (MIC) 0.5µg/mL and ≥0.5µg/mL respectively - was administered. CONCLUSIONS: Although the patient died due to complications of a Klebsiella pneumoniae sepsis refractory to treatment, the progression of the fungal disease, although slow, was favourable in the early phases of the treatment due to a correct diagnosis and the antifungal susceptibility test carried out. Clinical cases of this nature highlight the need to increase the epidemiological study of these microorganisms, as well as the proper treatment of the diseases caused, in order to achieve early diagnoses that reduce the morbidity and mortality of patients.

Oral florid papillomatosis: Topical treatment with 5% imiquimod in orabase.

BACKGROUND: Florid oral papillomatosis is characterized by its tendency to local recurrence that requires multiple treatments, leading to important functional sequelae. METHODS: We present 74-year-old woman with oral florid papillomatosis (OFP) who refused a new surgical treatment, and was treated with imiquimod 5% in orabase on alternate days for 16 weeks. Treatment was complemented with application of hyaluronic acid gel. RESULTS: There were no side effects to the treatment, nor signs of local recurrence, in the treated area at 2 years of follow-up. CONCLUSIONS: After reviewing the literature and according to our knowledge, this is the first published case of oral florid papillomatosis treated topically with imiquimod 5% successfully. Topical treatment with imiquimod 5% in orabase may be a valid alternative for patients with recurrent OFP located in the anterior area of the oral cavity who refuse surgical treatment, although we must closely monitor the patient for the possibility of recurrence or malignant degeneration.

Adherence, colonization and dissemination of Candida dubliniensis and other Candida species.

Adherence to host cells is essential for yeasts to develop their full pathogenic potential since it triggers the process that leads to colonization and enables their persistence in the host. The aim of this work was to study the in vitro adherence of Candida dubliniensis and other Candida species, as well as the relation of adherence with the colonization and dissemination of these yeasts in an experimental mice model. Clinical isolates of Candida dubliniensis, Candida albicans, Candida glabrata, Candida krusei, Candida parapsilosis and Candida tropicalis were tested for their in vitro ability to adhere to buccal epithelial cells and in vivo to colonize and disseminate in an experimental infant mice model. Although C. dubliniensis isolates showed variable adherence values, their ability to colonize and disseminate in mice tissue was almost null. All C. albicans strains showed high levels of adherence and a prolonged gastrointestinal (GI) tract colonization. Both C. glabrata and C. krusei, showed a minor in vitro adherence and limited colonization time in infant mice GI tract. C. albicans and C. parapsilosis demonstrated a higher ability to disseminate, but the other non-C. albicans Candida strains showed a lower ability to disseminate. This study demonstrates that C. dubliniensis has a low GI tract colonization ability, as well as low dissemination ability in relation to C. albicans.

Soybean sudden death syndrome species diversity within north and South america revealed by multilocus genotyping.

Sudden death syndrome (SDS) of soybean has become a serious constraint to the production of this crop in North and South America. Phenotypic and multilocus molecular phylogenetic analyses, as well as pathogenicity experiments, have demonstrated that four morphologically and phylogenetically distinct fusaria can induce soybean SDS. Published molecular diagnostic assays for the detection and identification of these pathogens have reported these pathogens as F. solani, F. solani f. sp. glycines, or F. solani f. sp. phaseoli, primarily because the species limits of these four pathogens were only recently resolved. In light of the recent discovery that soybean SDS and Phaseolus and mung bean root rot (BRR) are caused by four and two distinct species, respectively, multilocus DNA sequence analyses were conducted to assess whether any of the published molecular diagnostic assays were species-specific. Comparative DNA sequence analyses of the soybean SDS and BRR pathogens revealed that highly conserved regions of three loci were used in the design of these assays, and therefore none were species-specific based on our current understanding of species limits within the SDS-BRR clade. Prompted by this finding, we developed a high-throughput multilocus genotyping (MLGT) assay which accurately differentiated the soybean SDS and two closely related Phaseolus and mung BRR pathogens based on nucleotide polymorphism within the nuclear ribosomal intergenic spacer region rDNA and two anonymous intergenic regions designated locus 51 and 96. The single-well diagnostic assay, employing flow cytometry and a novel fluorescent microsphere array, was validated by independent multilocus molecular phylogenetic analysis of a 65 isolate design panel. The MLGT assay was used to reproducibly type a total of 262 soybean SDS and 9 BRR pathogens. The validated MLGT array provides a unique molecular diagnostic for the accurate identification and molecular surveillance of these economically important plant pathogens.

Primary metabolism changes triggered in soybean leaves by Fusarium tucumaniae infection.

Sudden death syndrome (SDS) of soybean can be caused by at least four distinct Fusarium species, with F. tucumaniae being the main causal agent in Argentina. The fungus is a soil-borne pathogen that is largely confined to the roots, but damage also reaches aerial part of the plant and interveinal chlorosis and necrosis, followed by premature defoliation can be observed. In this study, two genetically diverse soybean cultivars, one susceptible (NA 4613) and one partially resistant (DM 4670) to SDS infection, were inoculated with F. tucumaniae or kept uninoculated. Leaf samples at 7, 10, 14 and 25 days post-inoculation (dpi) were chosen for analysis. With the aim of detecting early markers that could potentially discriminate the cultivar response to SDS, gas chromatography-mass spectrometry (GC-MS) analyses and biochemical studies were performed. Metabolic analyses show higher levels of several amino acids in the inoculated than in the uninoculated susceptible cultivar starting at 10 dpi. Biochemical studies indicate that pigment contents and Rubisco level were reduced while class III peroxidase activity was increased in the inoculated susceptible plant at 10 dpi. Taken together, our results indicate that the pathogen induced an accumulation of amino acids, a decrease of the photosynthetic activity, and an increase of plant-specific peroxidase activity in the susceptible cultivar before differences of visible foliar symptoms between genotypes could be observed, thus suggesting that metabolic and biochemical approaches may contribute to a rapid characterization of the cultivar response to SDS.

Psychosocial Processes of Discrimination Against Women in the Workplace / Procesos Psicosociales de Discriminación contra la Mujer en el Lugar de Trabajo

Abstract This work aimed to analyze the influence of stereotypes on discrimination against women. Specifically, it investigated the effects of the candidate gender (man vs. woman), the status regarding parental leave (exercising the right vs. waiving the right), and the stereotypes of competence, sociability, and morality regarding this discrimination. Consistent with previous studies, the candidate gender and the parental leave status interact and together influence discrimination against women (Study 1, F(I, 229)=22.45, p<.001). In turn, the triple interaction of candidate gender, parental leave status, and the three dimensions of stereotypes (Study 2, F(4, 587)=2.73, p=.030, η2=.018) revealed that the woman who took parental leave received more positive evaluations in the three stereotypical dimensions, in comparison with to the woman who waived her right to the leave, and, at the same time, she was poorly assessed in the competence dimension, compared to the man who exercises the same right (Study 2, N=312).

Resumen El objetivo de este trabajo fue analizar la influencia de los estereotipos en la discriminación contra la mujer. Específicamente, se investigó los efectos del género candidato (hombre frente a mujer); el estado con respecto al permiso parental (ejercicio del derecho frente a la renuncia al derecho) y los estereotipos de competencia, sociabilidad y moralidad sobre esta discriminación. De acuerdo con estudios anteriores, el género de los candidatos y el estado de licencia parental interactúan e influyen juntos en la discriminación contra las mujeres (Estudio 1, F(I, 229) =22.45, p<.001). A su vez, la triple interacción del género candidato, el estado de licencia parental y las tres dimensiones de los estereotipos (Estudio 2, F(4, 587)=2.73, p=.030, η2=.018) revelaron que la mujer que tomó la licencia de paternidad se evaluó de manera más positiva en las tres dimensiones estereotipadas, en comparación con la mujer que renunció a su derecho a la licencia quien, al mismo tiempo, se evaluó de manera más pobre en la dimensión de competencia en comparación con el hombre que ejerce el mismo derecho (Estudio 2, N=312).
