Diagnostic Implication of Phosphatase and Tensin Homolog Expression in Endometrial Lesions

Background: Expression of Phosphatase and Tensin homolog (PTEN) is lower in endometrial cancer in comparison with normal or hyperplastic endometrium. Loss of PTEN function by mutational or other mechanisms is an early event in endometrial tumorigenesis. Objective: In this study, we evaluated PTEN gene expression in hyperplastic and malignant endometrium to assess its diagnostic implications. Methods: This study was conducted on women presenting with abnormal uterine bleeding (AUB), attending the Outpatient and Inpatient Clinics of Obstetrics and Gynecology. Endometrial biopsy sections were routinely stained with HandE stain and immunohistochemical staining for PTEN expression was performed in all the endometrial lesions. Results: The study comprised 278 cases of endometrial hyperplasias and carcinomas. In simple hyperplasia without atypia (n=143), 80.0% showed intense PTEN positivity and 20.0% showed moderate PTEN positivity. Simple hyperplasia with atypia (n=15), 93.3% cases showed moderate PTEN positivity and 6.7% case showed intense PTEN positivity. Complex hyperplasia without atypia (n=76), 14.4% cases showed mild PTEN positivity and moderate PTEN positivity was seen in 85.6% cases. Complex hyperplasia with atypia (n=34), 85.3% cases showed mild PTEN positivity and absent staining in14.7% cases. Adenocarcinoma cases showed mild PTEN positivity in 10.0% and absent staining in 90.0% cases. Conclusions: PTEN expression decreases as the lesion progress from benign to frank malignancy, and loss of PTEN function is an early event in the pathogenesis of endometrial carcinogenesis.
Tools for the Improvement of the Efficiency and Sustainability of Shore Nourishments – Results of the research project STENCIL

Shore nourishments have been carried out worldwide for several decades and are nowadays seen as an almost routine coastal protection measure. However, the recent paradigm shift to an Integrated Coastal Zone Management (ICZM) and to an Ecosystem Approach to Management (EAM) requires new concepts, models and tools for the implementation of more sustainable and environmentally friendly shore nourishments. The interdisciplinary research project STENCIL aimed at making a first step towards the long-term goal of es- tablishing an EAM for shore nourishments. Joining the expertise of coastal engineers, ge- ologists and ecologists, the project has provided improved tools and methods for the pre- diction of coastal hydro- and morphodynamics and related ecological impacts. A combination of field measurements, laboratory experiments and analytical as well as nu- merical models has resulted in valuable new data sets. This paper summarizes the most important scientific outcomes of the project, like the use of Artificial Neural Networks (ANN) to overcome weaknesses of current hydrodynamic numerical modelling tools; the analysis and interpretation of long-term beach profile data using a newly developed data- driven methodology, allowing for a better assessment of the morphological development of beach and foreshore nourishments; the improvement of a sediment transport model for mixed sand based on a unique large-scale experiment in the Large Wave Flume (GWK) carried out within the project; an impact assessment of dredging activities around Sylt, based on six extensive survey cruises at the sand extraction sites “Westerland II & III”; and the application of the hydrotoxicology method for the same study site to determine the influence of sand extraction on chemical-physical water quality parameters and the ecotox- icological potential. These interdisciplinary project results were combined with a compre- hensive state of the art review in a SWOT analysis for shore nourishments, which shall provide a tool for decision-makers and a basis for upcoming research projects addressing the identified knowledge gaps.
The effects of corporate venture capital on value creation and innovation of European public owned firms

The practice of corporate venture capital (CVC) has been widely adopted by corporations that invest in highly disruptive start-ups with the aim of fueling innovation and gain strategic advantages. Even if a wide consensus exists on the strategic benefits and performance of CVC investors in the North American venture capital industry, scarce information is available on the European CVC ecosystem. Therefore, the scope of this research is to investigate whether CVC activity, measured as the number of investments, deal size, and the number of realized exits is beneficial for value creation and innovation for European listed companies. Using a panel of CVC investors linked to European listed firms, it is found evidence that CVC activity creates firm value in the period under consideration (2008–2019), confirming North American’s past evidence. Surprisingly, exits convey a negative effect on firm value, suggesting that CVC performance may not be satisfactory enough. Moreover, when considering innovation, evidence is presented that investing in rounds with a higher deal size positively affects investor’s patenting levels, indicating that the later the start-up’s stage in its life cycle, the higher the possibility for the CVC investor to effectively absorb its technology. The relationship is true also for lagged CVC activity, confirming deferred effects on innovation demonstrated on US companies. The findings shed light on the European CVC ecosystem and give room for additional research on CVC investors’ exit performance and co-investors’ benefits on patenting levels

Quantification of enzymes related to insecticide resistance in Bemisia tabaci from the state of Sinaloa

The whitefly Bemisia tabaci (Gennadius) is one of the most invasive pests and causes direct damage to crop by feeding on the sap and indirect damage by being a vector of more than 100 phytopathogenic viruses. At present its control is based on the use of chemical insecticides, because the populations have been constantly subjected to a high selection pressure. An alternative that contributes to understanding the origin of resistance in a population are biochemical tests, which show the parameter of the detoxifying enzyme present. The objective of the present work was the quantification of these enzymes in B. tabaci in the three main solanaceae producing areas of the north (Guasave, Sinaloa de Leyva, Mochis), center (Culiacán, Navolato, Elota) and south (Concordia, Rosario, Esquinapa) of the state of Sinaloa. Whitefly adults were collected at these sites and the enzymatic levels of α and β esterases, glutathione S-transferases, aceticolinesterases and oxidases were determined, additionally a susceptible laboratory line was used as a reference. The enzymes with the highest presence were α-esterases, β-esterases and oxidases, followed by glutathione S-transferases and acetylcholinesterase. Therefore, it is concluded that resistance to insecticides in B. tabaci in the state of Sinaloa is due to the high content of α β-esterases and oxidases, while acetylcholinesterase is not a relevant mechanism in the populations of this producing region.

The Pathogenesis Based on the Glymphatic System, Diagnosis, and Treatment of Idiopathic Normal Pressure Hydrocephalus

: Idiopathic normal pressure hydrocephalus (iNPH) is a rare neurological disorder with no clear prevalence factors and is a significant danger to the elderly. The intracranial glymphatic system is the internal environment that maintains brain survival and metabolism, and thus fluid exchange changes in the glymphatic system under various pathological conditions can provide important insights into the pathogenesis and differential diagnosis of many neurodegenerative diseases such as iNPH. iNPH can be diagnosed using a combination of clinical symptoms, imaging findings and history, and cerebrospinal fluid biomarkers due to the glymphatic system disorder. However, only few researchers have linked the two. Shunt surgery can improve the glymphatic system disorders in iNPH patients, and the surgical approach is determined using a combination of clinical diagnosis and trials. Therefore, we have composed this review to provide a future opportunity for elucidating the pathogenesis of iNPH based on the glymphatic system, and link the glymphatic system to the diagnosis and treatment of iNPH. The review will provide new insights into the medical research of iNPH.
Affinity of class I and class III peroxidases for H2O2 in pepper leaves of different maturity

Paper deals with activities of Class III peroxidases (POX, EC 1.11.1.7) and Class I peroxidases (ascorbate peroxidase, APX, EC 1.11.1.11) as well as the Kmof these enzymes for hydrogen peroxide (H2O2) in the pepper leaves of different maturity. The obtained results suggest that the youngest pepper leaves compared to more mature ones have different strategies for H2O2 removal. There was an increase in APX activity with leaf maturity, while POX activity had the opposite trend, and its lowest activity was observed in the oldest leaves. The accumulation of reducing substrates i.e., ascorbate and total phenols was in positive correlation with corresponding enzymes following leaf maturity. The comparison of POX and APX affinity for H2O2 in pepper leaves of different maturity and their relationship between these enzymes’ activities were showed.
Soil property distribution following oil well access road removal in North Dakota, USA

Abstract: Increases in oil extraction on public lands in the US northern Great Plains has created an extensive network of access roads that must be removed upon well abandonment. However, the effects of road removal on soil properties are largely unknown. The objective of this study was to determine whether soil properties were altered on removed roadbeds and whether time since road removal has improved soil properties. Soils were sampled (n = 208) on perpendicular transects across removed roadbeds and extending into undisturbed areas on 16 restored roads located on two ecological site classifications such as (i) thin loamy and (ii) sandy. A Bayesian hierarchical mixed model was used to determine posterior predictive distributions and means of measured particle size distribution, gravel content, infiltration rate, pH, electrical conductivity, sodium adsorption ratio, CaCO3 content, and organic matter. Alterations in the predicted distribution of particle size, pH, CaCO3 content, and sodium adsorption ratio were attributed to mixing topsoil with subsoil during the road removal process. Soil organic matter decreased on roads. Most importantly, measured soil properties on removed roads did not improve with time since road removal. The alterations in soil properties can have lasting effects on nutrient availability, vegetation dynamics, and ecological resiliency of the native prairie.

Protective Role of trans-Chalcone against the Progression from Simple Steatosis to Non-alcoholic Steatohepatitis: Regulation of miR-122, 21, 34a, and 451

Purpose: Non-alcoholic steatohepatitis (NASH) is an inflammatory disorder and an aggressive form of fatty liver disease. Certain microRNAs, including miR-122, 21, 34a, and 451, are involved in the transition from steatosis to NASH. This study examined how trans-chalcone (the core of chalcone derivatives) affects NAFLD progression by regulating miRNAs. Methods: Male rats were divided into three groups (n = 7/group) as follows: control, rats were gavaged with 10% tween 80 (for two weeks); NASH, rats were gavaged with a high-fat liquid diet (HFD; for six weeks) and 10% tween 80 (for two weeks); NASH + Chal, rats were gavaged with the HFD (for six weeks) and trans-chalcone (for two weeks). Hepatic expression levels of miR-122, 21, 34a, and 451 were determined. Results: trans-Chalcone reversed histological abnormalities, reduced liver injury markers, and attenuated insulin resistance in HFD-fed rats. In the liver, HFD-induced NASH increased the expression level of miR-34a and decreased expression levels of miR-122, 21, and 451. However, trans-chalcone inhibited HFD-induced changes in expression levels of these miRNAs. Conclusion: trans-Chalcone could inhibit the transition from steatosis to NASH through the modulation of miR-122, 21, 34a, and 451 expression levels in the liver.
Corporate governance and financial performance of listed companies: A case of an emerging market

Corporate financial performance (CFP) is a key benefit that comes with the adoption and implementation of a good corporate governance structure in organizations. The objective of this paper is to analyze the effect of the six (6) broad corporate governance structures (board composition, board committees, separation of CEO/chairman, size of board, number of board meetings held, and shareholder concentration) on CFP measured by ROA, ROE, EPS, and Tobin’s Q among Ghanaian companies. The target population for the study was the companies that were listed on the Ghana Stock Exchange (GSE) for the period 2015–2020 and purposive sampling methods were deployed in the sample selection. The study found that using ROA as a performance indicator, corporate governance variables affected CFP by 18.95% whilst it influenced ROE by 29.71%. Additionally, corporate governance mechanisms impacted EPS by 52.53% when it was used as a performance indicator and 18.01% when Tobin’s Q was the performance index. The paper concludes that companies that implement the corporate governance guidelines on best practices stand a better chance of enhancing CFP especially with performance targets that integrate shareholder value maximization.
Exploring Civic Education as a Catalyst to Learner Transformation in Zambian Schools: A Glance on the Developed Civic Education Pedagogical Content Knowledge (CEPCK) Model

The main objective of this paper is to explore how Civic Education acts as a catalyst to learner transformation. The paper is structured in categories such as pedagogical content knowledge (PCK) model, and Civic Education pedagogical content knowledge (CEPCK) model among others. The author contends that in order for effective teaching and learner transformation to occur, teachers of Civic Education at both junior secondary school and senior secondary school should be knowledgeable with the learning outcomes which are specified in the school syllabi. In addition, Civic Education teachers should be equipped with relevant knowledge domains as outlined in the developed Civic Education pedagogical content knowledge model. Therefore, the developed Civic Education pedagogical content knowledge model may help different teaching/learning institutions in Zambia and beyond because it is a tool which can be used by administrators in various teaching and learning institutions to evaluate the competence levels of members of staff. In addition, the model may help teachers of Civic Education to deliver the subject effectively and impart learners with integrated knowledge, skills, values, dispositions and attitudes which may enable them not only to actively participate in community activities but also to be creative, live in harmony with others and be able to understand the contemporary society in which they live. It is therefore recommended that teachers of Civic Education in schools across the country should possess a variety of teacher knowledge as outlined in the developed Civic Education pedagogical content knowledge model (CEPCK) model in order to enhance not only effective delivery but also academic performance and learner transformation. In addition, the Ministry of General Education (MoGE), parents, teachers, administrators and other stakeholders should collaborate and come up with other strategies which can be used to enhance subject delivery and learners transformation. Also, universities, colleges of education and other various teacher training institutions in Zambia should adopt and include the developed Civic Education pedagogical content knowledge model in their curricular in order to equip Civic Education trainee teachers with knowledge domains as outlined in the developed model. Lastly, the researcher also recommends that the Ministry of General Education, the Curriculum Development Centre (CDC), Provincial Education Officers (PEOs) and District Education Board Secretaries (DEBS) and school administrators should ensure that schools adopt the use of the developed Civic Education pedagogical content knowledge model as well as encouraging them to incorporate it during their Continuous Professional Development (CPD) activities.
Hyaline Membrane Disease II: Lung Lecithin

and D. (1970). Archives in Childhood, 45, 311. Hyaline membrane disease. H: Lung lecithin. The lecithin content of lung, together with its surface tension properties, were determined in 34 stillbirths, and 61 neonatal deaths. Lecithin content ranged widely from 1-5 to 18 6% of dry lung tissue. In 24 cases the 'palmitic-lecithin' was also measured; it formed 44-79 % of the total lecithins. Since the two were related linearly, changes in palmitic-lecithin could be adequately studied by measuring total lecithins.
