Interspecific and intraspecific variation of ectomycorrhizal fungi associated with Eucalyptus ecosystems as revealed by ribosomal DNA PCR-RFLP

Gondwanan vegetation, and the Australian region in particular, is species rich for ectomycorrhizal fungi in epigeous and hypogeous forms with over 100 species recorded in small (1 ha) patches of forests. Distinguishing co-occurring ectomycorrhizal fungi as root associations in native (natural or wildlands) vegetation or plantations and discriminating them from other larger basidiomycetes, e.g. wood and leaf litter decomposer fungi, places large demands on molecular identification, especially if interspecific similarities and intraspecific variation occur in target sequences. One hundred and nine species of larger basidiomycetes from a single forest location were characterised by PCR-RFLP profiles of two genomic regions (nuclear rDNA ITS and mtLSU). Over one-third of the species for which multiple isolates were tested showed intraspecific variation in either one or both genomic regions. This remarkably high variation questions previous assumptions about intraspecific ITS sequence variation and highlights the value of integrated molecular and morphological databases including voucher specimens. It also emphasises the value of molecular investigations that use more than one genomic region. Interspecific similarities were common among the Cortinariaceae, especially in the ITS region. Discrimination of most Cortinariaceae species was achieved using variation in the mtLSU region in conjunction with the ITS. This new information raises the possibilities that the ITS sequence is more conserved and the mtLSU more variable than among species of the other 23 families. In the other families, interspecific ITS variation was greater and the mtLSU profiles grouped species within families. The high variation in the two genomic regions indicated possible differences in the fungal population structure between two adjacent, differently managed blocks of Eucalyptus marginata forest. The significance of this variation to ecology, biodiversity assessment and ecosystem management are discussed.
GOLPH3 Promotes Angiogenesis of Lung Adenocarcinoma by Regulating the Wnt/β-Catenin Signaling Pathway

Purpose We aim to investigate the role of Golgi phosphoprotein 3 (GOLPH3) and the possible regulation mechanism underlying lung adenocarcinoma (LADC). Methods The level of GOLPH3 was performed by quantitative real time (qRT)-PCR, Western blot and immunohistochemistry. Patient survival rate was analyzed by Kaplan–Meier method. MTT was used to detect cell viability. The levels of p-serine/threonine-protein kinase (Akt), Akt, p-p65, p65 and β-catenin were determined by Western blot. Cell apoptosis was tested using flow cytometry. Angiogenesis was determined by in vitro angiogenesis assay. qPCR and Western blot were performed to identify apoptotic protein B-cell lymphoma 2 (Bcl-2)/Bcl-2-associated X protein (Bax) and vascular endothelial growth factor (VEGF). Results GOLPH3 was highly expressed in LADC cell lines and tissues and was significantly correlated with poor overall survival among patients with LADC. Furthermore, GOLPH3 expression was reduced in A549 and H23 cells in a cisplatin-dependent manner. Silencing of GOLPH3 enhanced inhibition of A549 and H23 cells by cisplatin and suppressed the protein expression of p-Akt, while p-p65 expression remained stable. However, overexpression of GOLPH3 weakened the inhibition of A549 and H23 cells by cisplatin and improved the protein expression of p-Akt, while p-p65 expression remained stable. XAV939, an inhibitor of Wnt/β-catenin signaling pathway, decreased GOLPH3 overexpression-induced proliferation and enhanced cisplatin-induced angiogenesis inhibition and apoptosis, which was supported by the changes of VEGF, Bax and Bcl-2. Conclusion GOLPH3 promotes proliferation capacity in LADC through activating the Wnt/β-catenin signaling pathway.
Effect of feeding and genotype on the lipid profile of organic chicken meat

The effects of partial substitution of soybean (SB) with faba bean (FB) and of genotypes [fast-growing Cobb 700 (FG), medium-growing naked-neck Kabir (MG), slow-growing Brown Classic Lohman (SG)] on the lipid composition as well as the meat quality attributes of chickens reared under organic conditions were evaluated. A total of 720 1-day-old male chicks were equally divided into three groups according to genotype and raised for 81 (MG and FG) or 96 days (SG): half birds of each genotype received either SB grower diet or FB grower diet. Meat from SG and MG birds exhibited a lower lipid content than that from FG birds. Both in breast and thigh meat, MUFA were significantly increased from SG to MG and FG. SG meat contained the highest amounts of either arachidonic acid, eicosapentaenoic acid, docosahexaenoic acid, or docosapentaenoic acid, but the lowest amounts of α-linolenic acid. Total PUFA gradually decreased from SG to MG and FG birds (413, 358, and 324 g/kg of fat), as well as total n ― 6 and total n ― 3. The Δ 5 - plus Δ 6 -desaturase index was 54.0, 34.4, and 23.6 for SG, MG, and FG birds, respectively. The n — 6/n — 3 ratio was lower in SG and MG than in FG birds. The partial replacement of SB with FB had a lesser effect than the genotype on the meat quality characteristics.
Induction of apoptosis by Rhizoma Paridis saponins in MCF-7 human breast cancer cells

This study investigates the relationship between the induction of MCF-7 human breast cancer cell apoptosis by Rhizoma Paridis saponins (RPS) and the mitochondrial apoptotic pathway. We treated MCF-7 cells with RPS at various concentrations and examined the inhibitory effect of RPS on the proliferation of MCF-7 cells using the 4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, the change in mitochondrial membrane potential (MMP) using JC-1 staining, and the expression levels of related proteins using western blot. The results showed that the inhibitory effect of RPS against the growth of MCF-7 human breast cancer cells might be related to the apoptosis induced caspase family and the caspase-3-dependent pathway. The results suggest that RPS has the potential to be a valuable anticancer agent. Key words: Rhizoma paridis saponins, MCF-7 cells, apoptosis, mitochondria
Cytomorphological diagnosis of rapidly growing, hard, non-tender thyroid lesion

A 65-year-old male presented with rapidly growing left side thyroid swelling for the past 45 days. He complained of breathlessness and difficulty in eating food for a month. e patient did not have any other significant clinical history. On examination, the swelling measured 8 cm × 6 cm was nontender and hard in consistency. Ultrasound findings suggested a hyperechoic lesion in the left thyroid lobe measuring 8 cm × 5 cm × 4 cm. Fine needle aspiration cytology (FNAC) stained smears show the following findings [Figure 1a-d]. https://www.cytojournal. com/
Effects of Different Levels of Metabolizable Energy and Formulation of Diet Based on Digestible and Total Amino Acid Requirements on Performance of Male Broiler

In order to evaluate the effects of different levels of energy and method of formulation of Amino Acid (AA) requirements of diets, this experiment was conducted using 294 male broiler chicks. The experiment was carried out using a complete block design with a 7×2 factorial arrangement. Factors were included different level of energy (7 energy levels) and method of formulation of diets AA requirements (total and digestible). Method of formulation of AA requirement had no significant effect on cumulative feed consumption. Formulation of diet based on total or digestible AA had no significant effect on weight gain whereas high ME diets resulted in higher weight gain. Diets formulated based on total or digestible AA had feed conversion ratios that were not significantly different. Abdominal fat pad were significantly lower in chicks fed diets formulated on digestible AA basis. Energy content of diets affected fat pad significantly. Abdominal fat pad increased significantly as ME content of diets increased. Results obtained in our study suggest that even whit corn soybean meal based diets, formulation of diets AA requirement may be a beneficial tool for optimization of performance.
WINTER HARDINESS OF DURUM WHEAT IN HUNGARY

One basic precondition for the reliable cultivation of winter durum wheat (Triticum durum Desf.) in Hungary is for the varieties to have good winter hardiness and frost resistance. Field overwintering experiments carried out in Martonvasar between 1995 and 2003 demonstrated that there was a significant difference every year between the overwintering of varieties with poor and good frost resistance, though only in two years was there a significant difference between that of varieties with medium and better frost resistance. Only a medium correlation was observed between the mean annual values of the air temperature in the winter months and the winter hardiness of the varieties, confirming that winter hardiness is influenced jointly by a number of environmental factors (e.g. cold, snow cover). In the experiments carried out on the winter hardiness dynamics of durum wheat, it was found that in milder winters even T. durum varieties which are sensitive to frost overwintered with little damage, while in the tw.
Pediatric Residency Obesity and Overweight Training Curricula: A Systematic Review

Background. Pediatric obesity has become a significant public health concern. Pediatricians are the ideal group to help identify and treat this epidemic, but unfortunately, many pediatricians are not trained to discuss obesity with patients and their families. Standardized training initiatives for pediatric residents on prevention and/or management of obesity are needed to equip emerging pediatricians to combat the obesity epidemic. Objectives. This systematic literature review aims to examine the effectiveness of childhood obesity prevention/counseling resident training interventions. Methods. A comprehensive literature search was performed using preidentified search terms and limited to articles published prior to November 6, 2019. Articles were analyzed by 2 reviewers with a standardized evaluation tool. Results. A total of 698 articles were identified by the search. These were reduced to 111 articles after title review and 11 articles following abstract/full paper review. The 11 articles described 10 different obesity training interventions for residents. The articles varied in their size, length of training session, and study design. Despite these variations, all articles outlined positive outcomes, including an increase in physician confidence, positive changes in behavior, and/or improved electronic medical record documentation. Conclusions. With the continued increase in pediatric obesity, there is a need for practical, easy-to-implement, standardized trainings for pediatric residents on obesity prevention and treatment. More investigation needs to be done to look at long-term results of current interventions as well as other outcomes such as whether physicians are correctly identifying patients who are overweight or obese and whether there is improvement in patient follow-up.
Metabolic Flexibility and Innate Immunity in Renal Ischemia Reperfusion Injury: The Fine Balance Between Adaptive Repair and Tissue Degeneration

Renal ischemia reperfusion injury (IRI), a common event after renal transplantation, causes acute kidney injury (AKI), increases the risk of delayed graft function (DGF), primes the donor kidney for rejection, and contributes to the long-term risk of graft loss. In the last decade, epidemiological studies have linked even mild episodes of AKI to chronic kidney disease (CKD) progression, and innate immunity seems to play a crucial role. The ischemic insult triggers an acute inflammatory reaction that is elicited by Pattern Recognition Receptors (PRRs), expressed on both infiltrating immune cells as well as tubular epithelial cells (TECs). Among the PRRs, Toll-like receptors (TLRs), their synergistic receptors, Nod-like receptors (NLRs), and the inflammasomes, play a pivotal role in shaping inflammation and TEC repair, in response to renal IRI. These receptors represent promising targets to modulate the extent of inflammation, but also function as gatekeepers of tissue repair, protecting against AKI-to-CKD progression. Despite the important considerations on timely use of therapeutics, in the context of IRI, treatment options are limited by a lack of understanding of the intra- and intercellular mechanisms associated with the activation of innate immune receptors and their impact on adaptive tubular repair. Accumulating evidence suggests that TEC-associated innate immunity shapes the tubular response to stress through the regulation of immunometabolism. Engagement of innate immune receptors provides TECs with the metabolic flexibility necessary for their plasticity during injury and repair. This could significantly affect pathogenic processes within TECs, such as cell death, mitochondrial damage, senescence, and pro-fibrotic cytokine secretion, well-known to exacerbate inflammation and fibrosis. This article provides an overview of the past 5 years of research on the role of innate immunity in experimental and human IRI, with a focus on the cascade of events activated by hypoxic damage in TECs: from programmed cell death (PCD) and mitochondrial dysfunction-mediated metabolic rewiring of TECs to maladaptive repair and progression to fibrosis. Finally, we will discuss the important crosstalk between metabolism and innate immunity observed in TECs and their therapeutic potential in both experimental and clinical research.
Efficacy and Safety of Intravenous Thrombolysis on Acute Branch Atheromatous Disease: A Retrospective Case–Control Study

Background and Objective: Branch atheromatous disease (BAD) is distinctive from large-artery atherosclerosis and small-vessel disease, which is single subcortical infarction caused by the occlusion of perforator's orifice. This study aimed to indicate whether intravenous thrombolysis (IVT) with alteplase could prevent early neurological deterioration (END) and improve functional outcome for patients with BAD within 4.5 h after symptom onset. Methods: We retrospectively analyzed data collected from patients with BAD who were admitted to our hospital from January 2015 to August 2019. To investigate the efficacy and safety of IVT, subjects were classified into alteplase and control groups. A propensity score matching analysis was performed to control substantial heterogeneity of subgroup. The coprimary outcomes were END that is defined as an increase of ≥2 points in the National Institutes of Health Stroke Scale (NIHSS) score within 7 days after stroke, and favorable outcome at 3 months after stroke that defined by a score of 0–1 point on the modified Rankin scale (mRS). Results: A total of 135 patients were eventually enrolled in this study (n = 51 for the alteplase group and n = 84 for the control group). Additionally, 42 pairs of subjects were successfully matched by propensity score matching. Intravenous alteplase within 4.5 h after stroke onset reduced the incidence of END [unadjusted odds ratio (OR), 3.32; 95% confidence interval (CI), 1.06–10.37] and improved the clinical outcome at 3 months after stroke, with more patients achieving favorable functional prognosis (mRS, 0–1 point; unadjusted OR, 0.25; 95% CI, 0.10–0.62). Patients in the alteplase group were more likely to be independent (mRS, 0–2 points) at 3 months after stroke (unadjusted OR, 0.33; 95% CI, 0.12–0.90). The rate of death or dependence (mRS, ≥4 points) in the alteplase group was also markedly lower than that in the control group (unadjusted OR, 4.06; 95% CI, 1.03–16.02). Conclusion: Our findings indicated that intravenous thrombolysis may be a safe and effective therapy for patients with BAD.
Prognostic Performance of Different Lymph Node Staging Systems in Patients With Small Bowel Neuroendocrine Tumors

Background: The prognostic significance of the lymph node (LN) classification for small bowel neuroendocrine tumors (SBNETs) remains unknown. The aim of the present study was to evaluate and compare the prognostic assessment of different LN staging systems. Methods: Patients with SBNETs were identified from the Surveillance, Epidemiology, and End Results (SEER) database. The X-tile program was used to determine the cutoff value of the resected lymph nodes (RLNs), negative lymph nodes (NLNs), lymph node ratio (LNR), and the log odds of positive lymph nodes (LODDS). Survival analyses were performed using Kaplan–Meier curves with log-rank test. Logistic regression analysis was used to evaluate the differences between different periods. Univariate and multivariate Cox proportional hazards models were used to assess the prognostic value of different LN staging systems on cause-specific survival (CSS). The relative discriminative abilities of the different LN staging systems were assessed using the Akaike information criterion (AIC) and the Harrell consistency index (HCI). Result: A total of 3,680 patients were diagnosed with SBNETs between 1988 and 2014 from the SEER database. A significant difference over time (1988–1999 vs. 2000–2014) was seen in age (P <0.001), tumor differentiation (P <0.001), T stage (P <0.001), and RLN (P <0.001) subgroups. Multivariate Cox survival analysis identified that LN status stratified by the number of RLNs, NLNs, LNR, and LODDS all predicted CSS in patients with SBNETs (all P <0.05), whereas the number of positive lymph nodes (PLNs) failed (P = 0.452). When assessed using categorical variables, LODDS staging systems showed the best prognostic performance (HCI: 0.766, AIC: 7,575.154) in the whole population. Further analysis based on different RLNs after eliminating the missing data showed that when the RLNs are <12, the LODDS (HCI: 0.769, AIC: 1,088.731) maintained the best prognostic performance as well when the RLNs are ≥12 (HCI: 0.835, AIC: 825.692). Among patients with LNR scores of 0 or 1, there was a residual heterogeneity of outcomes that were better stratified and characterized by the LODDS. Conclusion: LODDS was a better predicator of survival when LN status was stratified as a categorical variable and should be considered when assessing the prognosis of patients with SBNETs to allow a more reliable means to stratify patient survival.
CD4 T Cell Responses and the Sepsis-Induced Immunoparalysis State

Sepsis remains a major cause of death in the United States and worldwide, and costs associated with treating septic patients place a large burden on the healthcare industry. Patients who survive the acute phase of sepsis display long-term impairments in immune function due to reductions in numbers and function of many immune cell populations. This state of chronic immunoparalysis renders sepsis survivors increasingly susceptible to infection with newly or previously encountered infections. CD4 T cells play important roles in the development of cellular and humoral immune responses following infection. Understanding how sepsis impacts the CD4 T cell compartment is critical for informing efforts to develop treatments intended to restore immune system homeostasis following sepsis. This review will focus on the current understanding of how sepsis impacts the CD4 T cell responses, including numerical representation, repertoire diversity, phenotype and effector functionality, subset representation (e.g., Th1 and Treg frequency), and therapeutic efforts to restore CD4 T cell numbers and function following sepsis. Additionally, we will discuss recent efforts to model the acute sepsis phase and resulting immune dysfunction using mice that have previously encountered infection, which more accurately reflects the immune system of humans with a history of repeated infection throughout life. A thorough understanding of how sepsis impacts CD4 T cells based on previous studies and new models that accurately reflect the human immune system may improve translational value of research aimed at restoring CD4 T cell-mediated immunity, and overall immune fitness following sepsis.
The σB-Mediated General Stress Response of Listeria monocytogenes: Life and Death Decision Making in a Pathogen

Sensing and responding to environmental cues is critical for the adaptability and success of the food-borne bacterial pathogen Listeria monocytogenes. A supramolecular multi-protein complex known as the stressosome, which acts as a stress sensing hub, is responsible for orchestrating the activation of a signal transduction pathway resulting in the activation of σB, the sigma factor that controls the general stress response (GSR). When σB is released from the anti-sigma factor RsbW, a rapid up-regulation of the large σB regulon, comprised of ≥ 300 genes, ensures that cells respond appropriately to the new environmental conditions. A diversity of stresses including low pH, high osmolarity, and blue light are known to be sensed by the stressosome, resulting in a generalized increase in stress resistance. Appropriate activation of the stressosome and deployment of σB are critical to fitness as there is a trade-off between growth and stress protection when the GSR is deployed. We review the recent developments in this field and describe an up-to-date model of how this sensory organelle might integrate environmental signals to produce an appropriate activation of the GSR. Some of the outstanding questions and challenges in this fascinating field are also discussed.
MRI Insights Into Adolescent Neurocircuitry—A Vision for the Future

Adolescence is the time of onset of many psychiatric disorders. Half of pediatric patients present with comorbid psychiatric disorders that complicate both their medical and psychiatric care. Currently, diagnosis and treatment decisions are based on symptoms. The field urgently needs brain-based diagnosis and personalized care. Neuroimaging can shed light on how aberrations in brain circuits might underlie psychiatric disorders and their development in adolescents. In this perspective article, we summarize recent MRI literature that provides insights into development of psychiatric disorders in adolescents. We specifically focus on studies of brain structural and functional connectivity. Ninety-six included studies demonstrate the potential of MRI to assess psychiatrically relevant constructs, diagnose psychiatric disorders, predict their development or predict response to treatment. Limitations of the included studies are discussed, and recommendations for future research are offered. We also present a vision for the role that neuroimaging may play in pediatrics and primary care in the future: a routine neuropsychological and neuropsychiatric imaging (NPPI) protocol for adolescent patients, which would include a 30-min brain scan, a quality control and safety read of the scan, followed by computer-based calculation of the structural and functional brain network metrics that can be compared to the normative data by the pediatrician. We also perform a cost-benefit analysis to support this vision and provide a roadmap of the steps required for this vision to be implemented.
