A review of recently introduced Aspergillus, Penicillium, Talaromyces and other Eurotiales species.

The order Eurotiales is diverse and includes species that impact our daily lives in many ways. In the past, its taxonomy was difficult due to morphological similarities, which made accurate identification of species difficult. This situation improved and stabilised with recent taxonomic and nomenclatural revisions that modernised Aspergillus, Penicillium and Talaromyces. This was mainly due to the availability of curated accepted species lists and the publication of comprehensive DNA sequence reference datasets. This has also led to a sharp increase in the number of new species described each year with the accepted species lists in turn also needing regular updates. The focus of this study was to review the 160 species described between the last list of accepted species published in 2020 until 31 December 2022. To review these species, single-gene phylogenies were constructed and GCPSR (Genealogical Concordance Phylogenetic Species Recognition) was applied. Multi-gene phylogenetic analyses were performed to further determine the relationships of the newly introduced species. As a result, we accepted 133 species (37 Aspergillus, two Paecilomyces, 59 Penicillium, two Rasamsonia, 32 Talaromyces and one Xerochrysium), synonymised 22, classified four as doubtful and created a new combination for Paraxerochrysium coryli, which is classified in Xerochrysium. This brings the number of accepted species to 453 for Aspergillus, 12 for Paecilomyces, 535 for Penicillium, 14 for Rasamsonia, 203 for Talaromyces and four for Xerochrysium. We accept the newly introduced section Tenues (in Talaromyces), and series Hainanici (in Aspergillus sect. Cavernicolarum) and Vascosobrinhoana (in Penicillium sect. Citrina). In addition, we validate the invalidly described species Aspergillus annui and A. saccharicola, and series Annuorum (in Aspergillus sect. Flavi), introduce a new combination for Dichlaena lentisci (type of the genus) and place it in a new section in Aspergillus subgenus Circumdati, provide an updated description for Rasamsonia oblata, and list excluded and recently synonymised species that were previously accepted. This study represents an important update of the accepted species lists in Eurotiales. Taxonomic novelties: New sections: Aspergillus section Dichlaena Visagie, Kocsubé & Houbraken.

KDM3A, a Novel Blood-Based Biomarker in Colorectal Carcinogenesis.

Colorectal cancer (CRC) is one of the leading causes of cancer-linked deaths globally. The determination of biomarkers is important in the prognosis and treatment of CRC. Previous studies emphasized the relationship between hypoxia and CRC in humans, and there is strong evidence that this process is strongly related to HIF-1. KDM3A is a histone demethylase that could directly bind to HIF-1α, a subunit of HIF-1. This study aimed to reveal whether the expression level of the KDM3A gene could be used as a predictor of CRC. The expression levels of HIF-1α, KDM3A, and Epithelial-Mesenchymal Transition (EMT) genes were evaluated by qRT-PCR in leukocyte samples of 50 CRC patients in different stages and 50 healthy controls. HIF-1α and KDM3A expression levels were significantly higher in the CRC group, compared to the controls. Slug and ZEB-1 genes, the mesenchymal markers, showed the same significance pattern between groups. We acquired 0.664 AUC with 54% sensitivity and 85.4% specificity for separating controls from CRC patients by using the KDM3A expression levels in ROC analysis. This data support that KDM3A could be a novel supplementary biomarker in diagnosis of CRC, which could be noninvasively detected in circulation.

The effect of spinal anesthesia that is performed in sitting or right lateral position on post-spinal headache and intraocular pressure during elective cesarean section.

Background: Although spinal anesthesia can be applied in different patient positions, the most frequently used positions are sitting and lateral positions. It is known that different patient positions during spinal anesthesia have effects on hemodynamic parameters, postdural puncture headache, and intraocular pressure. Aim: The study aimed to determine the effect of spinal anesthesia performed in either sitting or right lateral position on postspinal headache and intraocular pressure during elective cesarean section. Patients and Methods: The study was a randomized controlled study of 104 eligible pregnant women scheduled to undergo elective cesarean section. The women were randomized into two groups. Spinal anesthesia was performed either in the sitting (Group S, n = 53) or the right lateral position (Group L, n = 51). Heart rate and blood pressure were recorded throughout the operation. The participants were informed and monitored for postspinal headaches. Intraocular pressure before and after the operation was measured with Icare PRO. The obtained data were statistically compared between the two groups. Results: There was no difference between the groups in terms of demographic data. Postdural puncture headache was observed in five patients in Group S and one patient in Group L (P =0.04). There was no difference between the groups in terms of intraocular pressure (P >.05). Heart rate was not significantly different between the groups; however, there was a significant difference in average blood pressure in 1, 5, 30, and 40 minutes (P <.05). The number of trials administered to patients for spinal anesthesia was significantly higher in Group L (P =0.01). Conclusion: Spinal anesthesia performed in the sitting position for cesarean section caused a higher postspinal headache than in the right lateral position, but the position did not affect intraocular pressure.

Determination of the effect of two different methods of dental anesthesia on pain level in pediatric patients: A cross-over, randomized trial.

Background: In dentistry, needles are the most feared and anxiety-causing tool, making anesthetic injection a worrying practice for patients. Aim: To evaluate the effect of intraosseous anesthesia (IOA) and needle-free dental anesthesia (NFA) on pain levels in systemically healthy 8-10-year-old patients. Patients and Methods: Twenty patients aged 8-10 years were included in this cross-over study. Specifically, the pain was measured by Wong Baker, pulse rate (PR), and salivary opiorphin levels (SOL). In addition, the Frankl Behavioral scale was used to measure behaviors and face, legs, activity, cry, consolability (FLACC) was utilized to measure pain and discomfort. To determine the patients' anxiety levels Spielberger State-Trait Anxiety Scale (SSAS-SAAS) was used. The Friedman and Wilcoxon signed-rank tests were used. P < 0.05 was considered significant. Results: According to FLACC scores, IOA and NFA exhibited significantly pain alteration patterns in during local and topical anesthesia, respectively (p = 0.004, 0.001; P < 0.01). Also, only NFA showed significantly decreased SOL values in 5- and 10-min after local anesthesia periods compared to the before levels (p = 0.004, P = 0.001; P < 0.01). Conclusion: Patients feel similar pain perceptions during local anesthesia application in both injection systems. According to the SOL values, NFA may provide more higher anesthetic efficiency than IOA.

The Relationship of CRP/Albumin ratio level and prognosis in pregnant COVID-19 patients.

Background: The C-reactive protein (CRP)/albumin ratio (CAR) is one of the new tools to assess the severity of inflammation. It is used to determine clinical severity and prognosis in many diseases. Aim: The present study aimed to investigate the relationship between C-reactive protein (CRP)/albumin ratio (CAR) and prognosis in pregnant patients with more severe COVID-19 infection. Retrospective study. Patients and Methods: The study was conducted in a retrospective manner by scanning the files of pregnant patients who had a positive polymerase chain reaction test result and were hospitalized in Adiyaman Training and Research Hospital. The patients were divided into two groups: patients who were admitted to the intensive care unit and patients who were not admitted. CRP/albumin ratio (CAR) levels were compared between these two groups. The cut-off value was determined in the prediction of intensive-care admission and poor prognosis. Results: 117 patient files were reviewed. 13 patients were followed up with intensive care, whereas 104 patients completed their treatment in the service. The CAR levels of the patients admitted to intensive care were significantly higher (P < 0.01). In the estimation of intensive-care admission, the CAR level was determined to be 0.970 in the area under the curve with 100% sensitivity and 86.5% specificity in the receiver operating characteristic (ROC) curve. The cut-off CAR level was calculated as 1.8. Conclusion: CAR is a valuable biomarker for predicting prognosis, as well as follow-ups of pregnant COVID-19 patients.

Comparison of propofol-fentanyl and propofol-ketamine for sedoanalgesia in percutaneous endoscopic gastrostomy procedures.

Background: Percutaneous endoscopic gastrostomy (PEG) procedures are performed under sedation in critically ill patients who cannot be fed orally. Aim: We compared the efficacy and safety of propofol-fentanyl and propofol-ketamine for deep sedation in patients undergoing PEG. Retrospective Study. Materials and Methods: The study was conducted from 1 January 2013 to 31 December 2018 in Adiyaman University. The patients given propofol-fentanyl (0.5-1.2 mg/kg and 0.2-1 µg/kg, respectively) for sedo-analgesia were designated Group F, and those who received propofol-ketamine (0.2-0.6 mg/kg and 0.5-1 mg/kg, respectively) were placed in Group K. The demographic and hemodynamic characteristics, recovery times, perioperative complications, and need for additional doses were recorded. Results: Seventy-one patients who underwent PEG were analyzed. The age, sex, American Society of Anesthesiologists (ASA) score, comorbidities, duration of anesthesia, and duration of the PEG procedure were similar in the two groups. Recovery time was longer in Group K. The total propofol dose was 64 mg in Group F and 35 mg in Group K. Additional doses of propofol were administered to 12 patients in Group F, compared to none in Group K. The mean blood pressure values were higher in Group K at all-time points. The perioperative complication rate was higher in Group F. Desaturation was observed in 9 (22.5%) patients in Group F and in 3 (9.6%) patients in Group K. Hypotension was observed in 4 (10%) patients in Group F. Conclusion: Propofol-ketamine should be preferred for sedoanalgesia during PEG procedures because of the lower dose of propofol, more stable blood pressure, and greater peripheral oxygen saturation. In addition, we believe ketamine-propofol is safer based on its low complication rate.

The effect of hysterectomy types on vaginal length, vaginal shortening rate and FSFI scores.

OBJECTIVE: Vaginal length (VL), size and width may show individual differences among women. Hysterectomy causes VL shortening in patients, and this shortening varies according to the type of hysterectomy performed. Some studies in literature have shown that the shortened VL after hysterectomy may cause dyspareunia and have a negative effect on female sexuality. The aim of this study is to compare preoperative and postoperative vaginal lengths, vaginal shortening rate (VSR) not used before in the literature, and postoperative sexual functions according to hysterectomy types. MATERIALS AND METHODS: In the study, which included 136 [55 Total Abdominal Hysterectomy (TAH), 33 Vaginal Hysterectomy (VH), 48 Total Laparoscopic Hysterectomy (TLH)] sexually active patients under the age of 60 who underwent hysterectomy, the patients were divided into three groups according to the type of hysterectomy performed. Groups were compared in terms of demographic variables, preoperative/postop and control VL, vaginal shortening rate and The Female Sexual Function Index (FSFI) scores. RESULTS: Vaginal lengths measured after TLH was longer and vaginal lengths measured after VAH was shorter, the difference was significant (p < 0.01). VSRs were 15.9% in TAH group, 10.9% in VH group and 8.3% in TLH group (p < 0.05). Total FSFI score was higher in TLH group than TAH and VH group (p < 0.01). Group of VSR>15% had statistically significantly lower FSFI scores in lubrication, orgasm, pain and total score than both the VSR<10% group and the VSR 10-15% group (p < 0.05). CONCLUSION: Calculating the VSR after hysterectomy instead of postoperative VL measurement will allow us to obtain more individual and accurate results in predicting postoperative sexual functions. We found that TLH is the best hysterectomy method in terms of preserving sexual functions due to less loss of vaginal tissue in the postoperative period from these three techniques that are frequently.

Psychological domain of quality of life, depression and anxiety levels in in vitro fertilization/intracytoplasmic sperm injection cycles of women with endometriosis: a prospective study.

OBJECTIVE: To evaluate the psychological domain of quality of life (PDQoL), anxiety and depression levels of infertile women with endometriosis versus non endometriosis who applied for Assisted Reproductive Technologies (ART). METHOD: This prospective case-control study compromised a total of 105 women who applied for IVF/ICSI program. Ninety-three women were divided into two groups as endometriosis (n = 37) and non-endometriosis (n = 56) after 12 patients who refused to participate in the study were excluded. The WHOQOL-BREF questionnaire, Beck Depression and Anxiety Inventory scales were used to determine the psychological stress levels. RESULTS: A significant difference was found between the endometriosis and non-endometriosis groups regarding depression scores, while no significant difference was reported with respect to PDQoL and anxiety (p < 0.01, p = 0.897 and p = 0.058, respectively). A weak but significant correlation was observed between depression and endometriosis (CC: 0.435, p < 0.01). Though anxiety scores were found to be higher in endometriosis group this can not reach statistical significance (p = 0.058). Impact of PDQoL, depression and anxiety scores on pregnancy outcomes were found to be insignificant. CONCLUSION: Women with endometriosis seem to be more susceptible to depression and anxiety than women without endometriosis. Although infertility treatment outcomes are not found to be significantly affected, the impact of depression and anxiety over ART treatment success merit further research.

Taxonomy of Aspergillus series Versicolores: species reduction and lessons learned about intraspecific variability.

Aspergillus series Versicolores members occur in a wide range of environments and substrates such as indoor environments, food, clinical materials, soil, caves, marine or hypersaline ecosystems. The taxonomy of the series has undergone numerous re-arrangements including a drastic reduction in the number of species and subsequent recovery to 17 species in the last decade. The identification to species level is however problematic or impossible in some isolates even using DNA sequencing or MALDI-TOF mass spectrometry indicating a problem in the definition of species boundaries. To revise the species limits, we assembled a large dataset of 518 strains. From these, a total of 213 strains were selected for the final analysis according to their calmodulin (CaM) genotype, substrate and geography. This set was used for phylogenetic analysis based on five loci (benA, CaM, RPB2, Mcm7, Tsr1). Apart from the classical phylogenetic methods, we used multispecies coalescence (MSC) model-based methods, including one multilocus method (STACEY) and five single-locus methods (GMYC, bGMYC, PTP, bPTP, ABGD). Almost all species delimitation methods suggested a broad species concept with only four species consistently supported. We also demonstrated that the currently applied concept of species is not sustainable as there are incongruences between single-gene phylogenies resulting in different species identifications when using different gene regions. Morphological and physiological data showed overall lack of good, taxonomically informative characters, which could be used for identification of such a large number of existing species. The characters expressed either low variability across species or significant intraspecific variability exceeding interspecific variability. Based on the above-mentioned results, we reduce series Versicolores to four species, namely A. versicolor, A. creber, A. sydowii and A. subversicolor, and the remaining species are synonymized with either A. versicolor or A. creber. The revised descriptions of the four accepted species are provided. They can all be identified by any of the five genes used in this study. Despite the large reduction in species number, identification based on phenotypic characters remains challenging, because the variation in phenotypic characters is high and overlapping among species, especially between A. versicolor and A. creber. Similar to the 17 narrowly defined species, the four broadly defined species do not have a specific ecology and are distributed worldwide. We expect that the application of comparable methodology with extensive sampling could lead to a similar reduction in the number of cryptic species in other extensively studied Aspergillus species complexes and other fungal genera.

Fusarium: more than a node or a foot-shaped basal cell.

Recent publications have argued that there are potentially serious consequences for researchers in recognising distinct genera in the terminal fusarioid clade of the family Nectriaceae. Thus, an alternate hypothesis, namely a very broad concept of the genus Fusarium was proposed. In doing so, however, a significant body of data that supports distinct genera in Nectriaceae based on morphology, biology, and phylogeny is disregarded. A DNA phylogeny based on 19 orthologous protein-coding genes was presented to support a very broad concept of Fusarium at the F1 node in Nectriaceae. Here, we demonstrate that re-analyses of this dataset show that all 19 genes support the F3 node that represents Fusarium sensu stricto as defined by F. sambucinum (sexual morph synonym Gibberella pulicaris). The backbone of the phylogeny is resolved by the concatenated alignment, but only six of the 19 genes fully support the F1 node, representing the broad circumscription of Fusarium. Furthermore, a re-analysis of the concatenated dataset revealed alternate topologies in different phylogenetic algorithms, highlighting the deep divergence and unresolved placement of various Nectriaceae lineages proposed as members of Fusarium. Species of Fusarium s. str. are characterised by Gibberella sexual morphs, asexual morphs with thin- or thick-walled macroconidia that have variously shaped apical and basal cells, and trichothecene mycotoxin production, which separates them from other fusarioid genera. Here we show that the Wollenweber concept of Fusarium presently accounts for 20 segregate genera with clear-cut synapomorphic traits, and that fusarioid macroconidia represent a character that has been gained or lost multiple times throughout Nectriaceae. Thus, the very broad circumscription of Fusarium is blurry and without apparent synapomorphies, and does not include all genera with fusarium-like macroconidia, which are spread throughout Nectriaceae (e.g., Cosmosporella, Macroconia, Microcera). In this study four new genera are introduced, along with 18 new species and 16 new combinations. These names convey information about relationships, morphology, and ecological preference that would otherwise be lost in a broader definition of Fusarium. To assist users to correctly identify fusarioid genera and species, we introduce a new online identification database, Fusarioid-ID, accessible at www.fusarium.org. The database comprises partial sequences from multiple genes commonly used to identify fusarioid taxa (act1, CaM, his3, rpb1, rpb2, tef1, tub2, ITS, and LSU). In this paper, we also present a nomenclator of names that have been introduced in Fusarium up to January 2021 as well as their current status, types, and diagnostic DNA barcode data. In this study, researchers from 46 countries, representing taxonomists, plant pathologists, medical mycologists, quarantine officials, regulatory agencies, and students, strongly support the application and use of a more precisely delimited Fusarium (= Gibberella) concept to accommodate taxa from the robust monophyletic node F3 on the basis of a well-defined and unique combination of morphological and biochemical features. This F3 node includes, among others, species of the F. fujikuroi, F. incarnatum-equiseti, F. oxysporum, and F. sambucinum species complexes, but not species of Bisifusarium [F. dimerum species complex (SC)], Cyanonectria (F. buxicola SC), Geejayessia (F. staphyleae SC), Neocosmospora (F. solani SC) or Rectifusarium (F. ventricosum SC). The present study represents the first step to generating a new online monograph of Fusarium and allied fusarioid genera (www.fusarium.org).

Ras2 is important for growth and pathogenicity in Fusarium circinatum.

In this study, we investigated to possible role of Ras2 in Fusarium circinatum- a fungus that causes pine pitch canker disease on many different pine species and has a wide geographic distribution. This protein is encoded by the RAS2 gene and has been shown to control growth and pathogenicity in a number of fungi in a mitogen-activated protein kinase- and/or cyclic adenosyl monophosphate pathway-dependent manner. The aim was therefore to characterize the phenotypes of RAS2 gene knockout and complementation mutants of F. circinatum. These mutants were generated by transforming protoplasts of the fungus with suitable split-marker constructs. The mutant strains, together with the wild type strain, were used in growth studies as well as pathogenicity assays on Pinus patula seedlings. Results showed that the knockout mutant strain produced significantly smaller lesions compared to the complementation mutant and wild type strains. Growth studies also showed significantly smaller colonies and delayed conidial germination in the knockout mutant strain compared to the complement mutant and wild type strains. Interestingly, the knockout mutant strain produced more macroconidia than the wild type strain. Collectively, these results showed that Ras2 plays an important role in both growth and pathogenicity of F. circinatum. Future studies will seek to determine the pathway(s) through which Ras2 controls these traits in F. circinatum.

EFFECTIVENESS OF UNILATERAL ADRENALECTOMY IN BILATERAL ADRENAL INCIDENTALOMA PATIENTS WITH SUBCLINICAL HYPERCORTISOLEMIA.

Objective: Unilateral adrenalectomy (UA) is an alternative for treatment in bilateral adrenal incidentaloma (AI) to avoid possible long-term risks of bilateral adrenalectomy. In this study, we aimed to evaluate the effectiveness of UA in bilateral AI patients with subclinical hypercortisolemia (SH). Method: A total of 35 patients were included in this study. The patients were divided into two groups; those who underwent UA (n=27) and patients without adrenalectomy (PWA) (n=8). Hormone tests related to cortisol mechanism were reviewed to analyze results at the time of diagnosis compared to the latest available results to figure out any changes in cortisol mechanism and determine whether SH has recovered or not. Results: Median age of PWA group were higher compared to UA group (p=0.03). Median duration of follow-up in groups were similar (p=0.3). In the PWA group, none of the patients recovered from hypercortisolemia during their follow-up. In UA group 92.6% of the patients went into remission, whereas during follow-up 3.3% had recurred and another 3.3% were found to have post-adrenalectomy persistent SH. Patients in UA group had lower final cortisol level following dexamethasone suppression (p=0.003) and higher final adrenocorticotrophic hormone (ACTH) levels (p=0.001) than patients in PWA group. In UA group, final basal cortisol level (p=0.009) and final cortisol level after 1 mg dexamethasone suppression test (DST) (p=0.004) were lower than corresponding levels at the time of diagnosis. Discussion: Our study demonstrates unilateral adrenalectomy targeting the side with the larger lesion is an effective approach to reduce excess cortisol levels in bilateral AI patients with SH.

Redefining species limits in the Fusarium fujikuroi species complex.

The Fusarium fujikuroi species complex (FFSC) includes more than 60 phylogenetic species (phylospecies) with both phytopathological and clinical importance. Because of their economical relevance, a stable taxonomy and nomenclature is crucial for species in the FFSC. To attain this goal, we examined type specimens and representative cultures of several species by employing morphology and phylogenetic analyses based on partial gene fragments of the translation elongation factor 1-alpha (tef1), beta-tubulin (tub2), calmodulin (cmdA), RNA polymerase largest subunit (rpb1) and RNA polymerase II second largest subunit (rpb2). Based on these results three new species were delimited in the FFSC. Two of these phylospecies clustered within the African clade, and one in the American clade. Epitypes were also designated for six previously described FFSC species including F. proliferatum and F. verticillioides, and a neotype designated for F. subglutinans. Furthermore, both F. acutatum and F. ophioides, which were previously invalidly published, are validated. Citation: Yilmaz N, Sandoval-Denis M, Lombard L, et al. 2021.

Resveratrol ameliorates hepatic injury and modulates hepatic biomarkers of regeneration, apoptosis and survival in a rat model of blunt hepatic trauma.

OBJECTIVE: To investigate the protective potential of resveratrol (RES) in blunt hepatic trauma (BHT) by exploring the anti-inflammatory and histopathologic effects as well as modulatory effects on hepatic biomarkers of acute injury, regeneration, apoptosis and survival in a rat model of BHT. METHODS: A total of 21 Wistar Albino rats (weighing 120-250 g) were separated into 3 groups (n = 7 for each group), namely control group (CON; standard feeding), BHT group (BHT; blunt hepatic trauma plus observation) and trauma plus BES group (BHT-RES; blunt hepatic trauma plus intraperitoneal injection of 10 mg/kg RES). Serum levels for aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH) and bilirubin were measured on Day 7 and rats were sacrificed for histopathological (inflammation scores) and immunohistochemical [expression of proliferation marker (Ki-67) and apoptosis-related markers (Bcl-2, and Bax)] analyses in resected liver tissue. RESULTS: The highest levels for serum AST (p = 0.002), ALT (p = 0.002) and LDH (p = 0.002) were obtained from BHT group of rats, as followed by BHT-RES and control groups, respectively. The highest scores for Ki 67 (p = 0.002 for each), Bcl 2 (p = 0.002 for each) and Bax (p = 0.002 for each) were obtained from BHT-RES group of rats, as followed by BHT and control groups, respectively. Inflammation scores were significantly higher in BHT vs BHT-RES group (2.42 ± 0.53 vs 1.42 ± 0.53; p = 0.001) and both groups had higher inflammation scores than the control group (0.0 ± 0.0; p = 0.001). CONCLUSION: In conclusion, our findings revealed for the first time that RES exerts promising hepato-ameliorative effects against blunt hepatic injury as evidenced by decreased inflammation scores, parallel with improved hepatic histology, decreased serum transaminase activity as well as enhanced modulatory effect on regenerative and apoptotic processes in RES-treated rats subjected to experimentally-induced blunt hepatic trauma (Tab. 1, Fig. 1, Ref. 37).

Classification of Aspergillus, Penicillium, Talaromyces and related genera (Eurotiales): An overview of families, genera, subgenera, sections, series and species.

The Eurotiales is a relatively large order of Ascomycetes with members frequently having positive and negative impact on human activities. Species within this order gain attention from various research fields such as food, indoor and medical mycology and biotechnology. In this article we give an overview of families and genera present in the Eurotiales and introduce an updated subgeneric, sectional and series classification for Aspergillus and Penicillium. Finally, a comprehensive list of accepted species in the Eurotiales is given. The classification of the Eurotiales at family and genus level is traditionally based on phenotypic characters, and this classification has since been challenged using sequence-based approaches. Here, we re-evaluated the relationships between families and genera of the Eurotiales using a nine-gene sequence dataset. Based on this analysis, the new family Penicillaginaceae is introduced and four known families are accepted: Aspergillaceae, Elaphomycetaceae, Thermoascaceae and Trichocomaceae. The Eurotiales includes 28 genera: 15 genera are accommodated in the Aspergillaceae (Aspergillago, Aspergillus, Evansstolkia, Hamigera, Leiothecium, Monascus, Penicilliopsis, Penicillium, Phialomyces, Pseudohamigera, Pseudopenicillium, Sclerocleista, Warcupiella, Xerochrysium and Xeromyces), eight in the Trichocomaceae (Acidotalaromyces, Ascospirella, Dendrosphaera, Rasamsonia, Sagenomella, Talaromyces, Thermomyces, Trichocoma), two in the Thermoascaceae (Paecilomyces, Thermoascus) and one in the Penicillaginaceae (Penicillago). The classification of the Elaphomycetaceae was not part of this study, but according to literature two genera are present in this family (Elaphomyces and Pseudotulostoma). The use of an infrageneric classification system has a long tradition in Aspergillus and Penicillium. Most recent taxonomic studies focused on the sectional level, resulting in a well-established sectional classification in these genera. In contrast, a series classification in Aspergillus and Penicillium is often outdated or lacking, but is still relevant, e.g., the allocation of a species to a series can be highly predictive in what functional characters the species might have and might be useful when using a phenotype-based identification. The majority of the series in Aspergillus and Penicillium are invalidly described and here we introduce a new series classification. Using a phylogenetic approach, often supported by phenotypic, physiologic and/or extrolite data, Aspergillus is subdivided in six subgenera, 27 sections (five new) and 75 series (73 new, one new combination), and Penicillium in two subgenera, 32 sections (seven new) and 89 series (57 new, six new combinations). Correct identification of species belonging to the Eurotiales is difficult, but crucial, as the species name is the linking pin to information. Lists of accepted species are a helpful aid for researchers to obtain a correct identification using the current taxonomic schemes. In the most recent list from 2014, 339 Aspergillus, 354 Penicillium and 88 Talaromyces species were accepted. These numbers increased significantly, and the current list includes 446 Aspergillus (32 % increase), 483 Penicillium (36 % increase) and 171 Talaromyces (94 % increase) species, showing the large diversity and high interest in these genera. We expanded this list with all genera and species belonging to the Eurotiales (except those belonging to Elaphomycetaceae). The list includes 1 187 species, distributed over 27 genera, and contains MycoBank numbers, collection numbers of type and ex-type cultures, subgenus, section and series classification data, information on the mode of reproduction, and GenBank accession numbers of ITS, beta-tubulin (BenA), calmodulin (CaM) and RNA polymerase II second largest subunit (RPB2) gene sequences.

The role of miRNAs targeting K-ras and APC genes in colorectal cancer.

OBJECTIVES: The occurrence of abnormal expression patterns in different types of cancer suggests that micro RNAs (miRNAs) may play an important role in tumorigenesis. The aim of this study was to examine the expression levels of miRNAs known to be associated with the regulation of the expression levels of the APC and K-ras, which are important in the development of colorectal cancer (CRC). METHODS: The expression levels of miR-27, miR-663, miR-217, miR-181d, APC and K-ras in the serum, tumor and adjacent tumor-free (healthy) tissues of the patients and serum of the healthy controls were investigated with qRT-PCR. RESULTS: Expression levels of miR-217, mR-181d, miR-663, miR-27 and K-ras were found to be higher in CRC tissues than in adjacent tumor-free tissues of the patients. In patient serum samples, miR-663 levels were statistically more elevated than in controls. In patient tumor tissues, miR-217, miR-181d and miR-27 expressions were found to be higher. CONCLUSIONS: Increased miR-181d and miR-217 expression levels are associated with increased K-ras expression in the tumor tissues, and the expression of K-ras, which takes part as an oncogene in the CRC development, might be regulated by these miRNAs (Tab. 4, Ref. 33).

Penicillium diversity in Canadian bat caves, including a new species, P. speluncae.

Penicillium species were commonly isolated during a fungal survey of bat hibernacula in New Brunswick and Quebec, Canada. Strains were isolated from arthropods, bats, rodents (i.e. the deer mouse Peromyscus maniculatus), their dung, and cave walls. Hundreds of fungal strains were recovered, of which Penicillium represented a major component of the community. Penicillium strains were grouped by colony characters on Blakeslee's malt extract agar. DNA sequencing of the secondary identification marker, beta-tubulin, was done for representative strains from each group. In some cases, ITS and calmodulin were sequenced to confirm identifications. In total, 13 species were identified, while eight strains consistently resolved into a unique clade with P. discolor, P. echinulatum and P. solitum as its closest relatives. Penicillium speluncae is described using macroand micromorphological characters, multigene phylogenies (including ITS, beta-tubulin, calmodulin and RNA polymerase II second largest subunit) and extrolite profiles. Major extrolites produced by the new species include cyclopenins, viridicatins, chaetoglobosins, and a microheterogenous series of cyclic and linear tetrapeptides.
