Effect of complete suppression of androstenedione on auxological development in prepubertal patients with classical congenital adrenal hyperplasia
Authors: Debor Belana , Bechtold-Dalla Pozza Susanne , Reisch Nicole , Schmidt Heinrich , Dubinski Ilja 
Published: August 2023

Abstract

Objectives
Children with classical congenital adrenal hyperplasia (CAH) require glucocorticoid (GC) substitution due to impaired cortisol synthesis. To avoid over- or undertreatment, one has to consider auxology as well as biochemical parameters for adrenal derived steroids like androstenedione (A4) and 17-hydroxyprogesterone (17-OHP). There are no established reference values for A4 and 17-OHP in CAH.

Methods
We performed a retrospective study in 53 prepubertal patients with CAH. Datasets of patients were included if the plasma A4 values of the respective clinical visit were under the limit of quantification. Related 17-OHP values were extracted as well as height/length, weight, dose of hydrocortisone, HC regimen, bone age and stages of pubertal development.

Results
Median hydrocortisone doses were in most observations within the recommended reference ranges. Hydrocortisone has a significant negative influence on 17-OHP values and HSDS. Age has a positive significant influence on 17-OHP, BMI-SDS, and HSDS. Median height standard-deviation-score (HSDS) was beneath 0 at all times, but showed an increasing trend in both sexes. Median body mass index standard-deviation-score (BMI-SDS) was above 0 at all times and showed an increasing trend as well.

Conclusions
With guideline-compliant doses of hydrocortisone, suppression of A4 at the respective time of day is possible in prepubertal children. Although HC has a significant negative influence on HSDS, increasing values for HSDS and HC are observed with increasing age. Thus, A4 suppression at the respective time point does not hinder regular growth. An increase in body mass index can already be observed as early as in prepuberty.

Abstract
Trace elements have a significant effect on biochemical reactions and therefore the presence of optimum levels of trace elements is essential for bioreactor performances. In this study, the effects of five trace elements on biomethane production have been investigated. Experimental studies have been carried out with multiple batch reactors at 15 day HRT and mesophilic temperatures. The optimum concentrations for each of the trace elements Fe, Cu, Ni, Co and Mg were found as 5, 0.5, 0.5, 0.5 and 100 mg/L, respectively. Among tested trace elements, Cu was the one which provided the highest biomethane production. Cu addition was resulted in a 46 % increase in biomethane production followed by Co with 24 %. The biomethane production rate for these two trace elements was 191.70 and 110.77 ml CH4/g COD, respectively. Optimum levels for Ni, Fe and Mg increased biomethane production rate by approximately 14.3, 10 and 17 % compared to control groups, respectively. Because the exact amount of trace element requirement for each industry/reactor is different, specific case studies should be performed for each application. These results could be used as initial trace element concentrations for further continuous studies.

Abstract
Early diagnosis of cancer is beneficial to improve the outcomes of clinical treatment and reduce cancer mortality. Nanomaterials (NMs) have exhibited significant advantages in early diagnosis of cancer. Due to the integrated structure and features of NMs, they can easily penetrate the tissue for the in vivo diagnosis and identify cancer cells after specific conjugation with unique markers expressed on or within the cancer cells based on the biological imaging such as Raman imaging, fluorescence imaging, and near-infrared imaging, whereas the NMs for the in vitro diagnosis can detect signals based on the electrochemical reactions, immune reactions, and colorimetric reactions, analyzing cancer markers such as small molecules, proteins (or enzymes), genetic materials or cells in the blood, urine, and saliva. NMs with novel physical properties facilitate the detection and imaging of low concentrations and enable the sensitive capture of small cancer biomarkers, achieving early cancer detection. However, a comprehensive summary of such NMs has not been reported. This article provides a detailed review of the types and diagnostic mechanisms of NMs for early cancer diagnosis, emphasizing new perspectives on the use of the in vivo and the in vitro NMs for early cancer diagnosis and proposing the development prospects of such NMs. This will provide new ideas and scientific references for the application of NMs in early cancer diagnosis.
Analytical solutions of the extended Kadomtsev–Petviashvili equation in nonlinear media
Authors: Althobaiti Saad , Althobaiti Ali 
Published: August 2023

Abstract
This manuscript attempts to construct diverse exact traveling wave solutions for an important model called the (3+1)-dimensional Kadomtsev–Petviashvili equation. In order to achieve that, the Jacobi elliptic function technique and the Kudryashov technique are chosen in favor of their noticeable efficacy in dealing with nonlinear dynamical models. As expected, the used approaches lead to a variety of traveling wave solutions of different types. Finally, we have graphically illustrated some of the obtained wave solutions to further make sense of their representation. Also, we provide an overview of the main results at the end.
The bipartite Laplacian matrix of a nonsingular tree
Authors: Bapat Ravindra B. , Jana Rakesh , Pati Sukanta 
Published: August 2023

Abstract
For a bipartite graph, the complete adjacency matrix is not necessary to display its adjacency information. In 1985, Godsil used a smaller size matrix to represent this, known as the bipartite adjacency matrix. Recently, the bipartite distance matrix of a tree with perfect matching was introduced as a concept similar to the bipartite adjacency matrix. It has been observed that these matrices are nonsingular, and a combinatorial formula for their determinants has been derived. In this article, we provide a combinatorial description of the inverse of the bipartite distance matrix and establish identities similar to some well-known identities. The study leads us to an unexpected generalization of the usual Laplacian matrix of a tree. This generalized Laplacian matrix, which we call the bipartite Laplacian matrix, is usually not symmetric, but it shares many properties with the usual Laplacian matrix. In addition, we study some of the fundamental properties of the bipartite Laplacian matrix and compare them with those of the usual Laplacian matrix.

Authors: Wan Keqiang , Su Chang , Yin Fang , Yao Caoyuan 
Published: August 2023

Abstract

Objectives

Pseudomonas aeruginosa is pathogenic in immunocompromised individuals. It has several complex mechanisms for evading human immunity. The objective of the study was to examine the secretory immunoglobulin A (sIgA) mediated immune response in saliva to detect P. aeruginosa in pulmonary tuberculosis.

Methods
The infection with P. aeruginosa was categorized according to the Leeds criteria in the final 86 individuals who were proven to have pulmonary tuberculosis by polymerase chain reaction. Levels of serum immunoglobulin G (IgG) and sIgA which are specific to P. aeruginosa were measured using the method of ELISA.

Results
Patients in the “free of infection (patients who were infected with P. aeruginosa in the lower respiratory tract at the beginning of the study later became negative)” and “intermittent colonized (patients who were infected with P. aeruginosa throughout the study)” groups had substantially higher median baseline sIgA levels in saliva and a much greater proportion of sIgA positive than patients who were never colonized (patients who were found to be P. aeruginosa negative throughout the study) (p=0.038). Median baseline IgG level was 10.7 (1.7–145.0), 8.3 (2.5–22.9), and 6.7 (3.3–17.1) for the patients categorized as “intermittent colonization”, “free of infection” and “never colonized”, respectively. After 3 years of study, sIgA level was found in significant high level among the patients with infection of P. aeruginosa (p=0.003).

Conclusions
Secretory IgA may be readily collected from saliva and is a useful diagnostic technique for determining whether P. aeruginosa infection has occurred.

Published: August 2023

Abstract: Leaders are almost always needed in a group or organizational situation, including a state, which has the purpose of making decisions. One style of leadership is authoritarian leadership. Leaders who embrace this leadership style are called dictators and the state or government led by dictators is called the dictatorship. However, empirical researches in psychology on dictatorship phenomena are still rarely done. Therefore, we expect this paper will encourage more empirical researches on this phenomenon in the field of psychology, especially social psychology. This article was written with a literature review approach from a variety of relevant sources: books, book chapters, review articles, and research articles. The perspective used is social psychological perspective because in our opinion it is more precise and comprehensive. The results of literature review show that dictatorship consists of three types: monarchic dictatorship, military dictatorship, and civilian dictatorship. The figure of a dictator in dictatorship state has narcissism trait classified in the Dark Triad characteristics. The dictatorship state has two main problems namely power-sharing and authoritarian control. Empirically, dictatorship practices have more negative than positive impacts on a state. In addition, dictatorship practices are also contrary to the nature of leadership should be played by a state leader.
Abstrak: Pemimpin hampir selalu dibutuhkan dalam situasi kelompok atau organisasi, termasuk dalam sebuah negara, yang memiliki tujuan untuk membuat keputusan. Salah satu gaya kepemimpinan adalah kepemimpinan otoriter yang identik dengan kepemimpinan sewenang-wenang. Pemimpin yang menganut gaya kepemimpinan ini disebut dengan diktator dan negara atau pemerintahan yang dipimpin oleh diktator disebut dengan kediktatoran. Namun demikian, penelitian empiris di bidang psikologi mengenai fenomena kediktatoran masih jarang dilakukan. Oleh karena itu, tulisan ini diharapkan dapat mendorong lahirnya riset-riset empiris di bidang psikologi, khususnya psikologi sosial, mengenai fenomena kediktatoran. Artikel ini ditulis dengan pendekatan telaah literatur (literature review) dari berbagai sumber yang relevan, baik itu berupa buku, book chapter, artikel telaah, maupun artikel penelitian. Perspektif yang digunakan adalah perspektif psikologi sosial karena dianggap lebih tepat dan komprehensif. Hasil telaah literatur menunjukkan bahwa kediktatoran terdiri dari tiga jenis, yaitu monarchic dictatorship, military dictatorship, dan civilian dictatorship. Sosok diktator dalam negara kediktatoran biasanya memiliki trait kepribadian narsisisme yang tergolong dalam karakteristik Dark Triad. Negara kediktatoran memiliki dua masalah utama yaitu power-sharing dan authoritarian control. Secara empiris, praktik kediktatoran memiliki lebih banyak dampak negatif daripada positif bagi sebuah negara. Selain itu, praktik kediktatoran juga bertentangan dengan hakikat kepemimpinan yang harusnya diperankan oleh seorang pemimpin negara.
