Authors: Ameur Hind , Gédéon Motsatsa Mosolino , Barkiche Samir , Oumghar Nezha , Omrani Abdelhamid El , Khouchani Mouna
Published: June 2024

Male breast cancer (MBC) is a rare disease, accounting for 1% of all breast cancers and 0.5% of all malignancies in men. While long considered stable, MBC incidence has increased 26% over the past 25 years. Despite this rise, MBC remains poorly recognized by the public and sometimes clinicians, risking delayed diagnosis and poor prognosis cases. This rarity also impacts treatment, as men have received little research attention and management largely relies on evidence from women. Currently, MBC has become a topic of interest to uncover similarities between males and females to better tailor therapeutic approaches. We present two cases - a 56-year-old man with a 2-year history of a 2cm retroareolar left breast mass, diagnosed as grade III invasive ductal carcinoma, and a 38-year-old man with a 4cm retroareolar left breast mass complicated by bloody nipple discharge, diagnosed as grade II invasive ductal carcinoma. Both underwent mastectomy and axillary dissection followed by adjuvant radiation and hormonal therapy. MBC diagnosis relies on triple assessment like female breast cancer. While rare, raising MBC awareness is crucial for timely diagnosis and management per evidence-based guidelines, warranting further research into this malignancy affecting men.

Introduction: Pubertal delay is defined by the absence of development of secondary sexual characteristics beyond the age of 13 in girls or 14 years in boys. In children of puberty age, delayed puberty is common in long-standing, untreated hypothyroidism. We report a case of delayed puberty revealed by Hashimoto's disease in the hypothyroid phase diagnosed in the Internal Medicine department of the Gabriel Touré University Hospital in Bamako, Mali. Observation: This was a female patient, aged 20 years old, without any particular medico-surgical ATCD or notion of taking medication, who had consulted at the end of 2021, in the Internal Medicine department of the University Hospital Gabriel Touré from Bamako for primary amenorrhea and delayed puberty. At the end of the clinical and paraclinical examination, a hypometabolism syndrome and pubertal delay were noted. On an evolutionary level, development of secondary sexual characteristics (From T1 to T3, and appearance of menstruation) after one year of treatment. Conclusion: Delayed puberty may be the consequence of hypothyroidism. Opotherapy with L Thyroxine helps restore normal pubertal development.

Authors: Makino Shinji
Published: June 2024

A 78-year-old woman presented with an upper visual field defect in the left eye. Her best-corrected visual acuity (BCVA) was 1.2 in both eyes. Fundoscopy revealed inferior optic disc swelling. Peripapillary optical coherence tomography (OCT) demonstrated the presence of peripapillary hyperreflective ovoid mass–like structures (PHOMS) that was located in the inferior portion of the left eye. The patient was diagnosed with nonarteritic anterior ischemic optic neuropathy (NAION) of the left eye. One month after the initial visit, her BCVA decreased to 0.15 in the left eye. Fundoscopy revealed superior optic disc swelling. OCT demonstrated the presence of PHOMS that was located in the superior portion of the left eye. She was diagnosed with recurrent NAION. Three months later, her BCVA was maintained at 0.2, however, the optic disc looked diffusely pale. This case highlights the importance for clinicians to be aware of PHOMS with NAION.

Authors: Selian Rada Almina , Hardisman Hardisman , Yulizawati Yulizawati , Firdawati Firdawati , Iffah Uliy
Published: June 2024

Background: Childbirth is the effort or process of expelling a full-term baby which is often accompanied by pain caused by contractions in the uterus. From the research results, it was found that 32% of 300 women who gave birth during the active phase experienced severe pain, 57% moderate pain, and 11% mild pain. Evidence shows that fear of vaginal childbirth and anxiety experienced by many women during their pregnancy. Therefore, it then led to their decision to choose other methods of birth such as Section Caesarea (SC). The effects of anxiety during labor could potentially result in excessive levels of catecholamines causing decreased blood flow to the uterus, decreased uterine contractions, decreased blood flow to the placenta, decreased oxygen available to the fetus, and can increase the length of labor. One of alternative methods of dealing with pain during the labor process is using non-pharmacological such as endorphin massage and oxytocin massage. Purpose: The aim of this literature study was to present information about the effect of endorphin massage and oxytocin massage on the intensity of pain among mothers giving birth.
Methods: This research method was a literature review study. Journal searches were carried out by applying online database such as ScienceDirect, Google scholar, Pubmed, Scopus, Portal Garuda. Articles were selected based on inclusion and exclusion criteria.
Result: The study investigated the influence of endorphin and oxytocin massages on pain intensity in maternity mothers during childbirth, revealing a significant reduction in pain levels following the administration of these massages. Both endorphin and oxytocin massages were found to alleviate pain, induce relaxation, and promote feelings of comfort and calmness, thereby facilitating a smoother birth process.
Conclusion: The influence of endorphin massage and oxytocin massage is useful in reducing pain in maternity mothers

This research centers on microbial, anions and chemical scrutinizes of 25 Abuja water samples, Nigeria. The cations, anions, soluble ions, trace elements, and heavy metal were obtained and compared with WHO standards. The mean highest anions, cations and bacteria counts were recorded as 1796.879 (Electrical conductivity), and least mean of F- 1.28mg/l, whereas standard deviation highest values were 857.13 µS/cm (EC), and lowest value of 0.45 mg/s (F-). Usually, the matrix values ranges between -1 and +1. Cl- and Alkalinity displays high positive connection (0.85), with K Plus Electrical conductivity (0.77). There is a negative correlation between HNO3 & Alkalinity, and F- & CO32- (-0.01). Four hydrochemical clusters were recognized from Hierarchical cluster scrutiny (HCS) with clearly partitioned water attribute. Series and time series plot reveals TDS concentration value between 1200 and 2100 mg/L, has the highest with the mean and SD are 1433.76 and 459.38 respectively. Results also confirm that, groundwater within the investigation zone is mostly hard to exceptionally hard, and faintly alkaline-fresh to briny in nature. From hydrochemistry illustration, the key groundwater categories are Ca, Na-Cl, Na-HCO3 and Mg-HCO3, which indicates that the groundwater within the investigated region are tolerably polluted with cations-anions, due to anthropogenic, ion exchange and mineral weathering.
Rack and Pinion Based Electricity Generation through a Speed Breaker: A Feasibility Study
Authors: Banu Selina
Published: June 2024

Electricity is an essential power source for the economic performance of a developing country like Bangladesh. Due to significant system losses, delays in the installation of new plants, low plant efficiency, and lack of incentives for power plant maintenance, the country's energy-producing facilities have been unable to fulfill the present demand. To meet up this enormous demand, a very simple electricity generation technology was designed. The objectives of the study were to design and fabricate a considerable electricity generation system from a speed breaker and finally determine the technical performance of the system. The production plant was set up using a rack and pinion system. The Damper system comprised of a spring that pushed the speed breaker upwards when it was pushed upon by the weight of the vehicle downwards during trafficking of any vehicles over the speed breakers. As a result, the Rack moved downward, transmitting power to the pinion as motion. The production unit was able to produce 4.2 watts, 6.72 watts, and 0.84 watts, respectively, using a motorcycle, a car, and an easy bike. Our fabricated plant has a total power output of 2683 kW. The unit's entire annual cost, including starting costs and total running costs, is projected to be around $269.65. The capital recovery factor and capital consumption were 0.395 and $44.87 respectively. The proposed design will be helpful to reduce the energy crisis problem in Bangladesh because nowadays in our country the number of vehicles is in increasing trend.

Published: June 2024

In this study, the perception, acceptance and usage status of Cyber Physical Systems (CPSs) which seem likely to become a more dominant tool in the industrial sector in the coming years, in manufacturing industry enterprises, and the advantages it provides to small and medium-sized enterprises (SMEs) in the manufacturing sector are examined in line with the requirements of the sector. In this regard, the study will offer comprehensive insights to researchers, scientists, and decision-makers within industrial sectors, as well as institutions and organizations tasked with making strategic decisions. In addition, as with any new technology, the importance of determining the attitudes of staff and managers, who are the users of the technology, towards CPS was evaluated with an acceptance model developed by considering industrial conditions. By applying a questionnaire with open-ended questions including the opinions of SMEs, it is aimed to examine the factors in the Unified Technology Acceptance and Utilization Theory (UTAUT) model whose effects on usage are advocated. analysis demonstrate that the major hesitations of the enterprises are concentrated on the high costs of the technology, the lack of human resource competence to use the systems and the lack of solution partners in case of possible failures, but they still have positive opinion about the use. The study's findings shed light on the factors influencing the feasibility of CPS technology in the industrial sector. These results can serve as a guide for conceptualization, policy support, planning, and the development of new management strategies that will be essential in this field in the forthcoming years.

Published: June 2024

The negative trends in the development of the Ukrainian economy are deepening more and more. A significant decrease in economic dynamics is largely caused by stressful changes in the socioeconomic and political environment, which is primarily due to the state of war in the country. These factors are based primarily on the predominance of raw materials in production and export, on the exploitation of outdated, environmentally dangerous and resource-intensive means of production, due to which the once powerful Ukrainian woodworking industry is increasingly declining. In such conditions, the revival of the woodworking industry in Ukraine requires the construction of a new model of economic development, which would be based on the effective mobilization and distribution of important investment resources in the organizational and technological development of the industry. The relationship of the woodworking industry with many other branches of the economy determines its role in the economic development of the state. In particular, in Ukraine, the products of the woodworking industry include more than three hundred products that are supplied to the domestic and foreign markets, and are also accompanied by close interaction with a number of industries that act as both consumers and suppliers. However, in the conditions of the existence of factors that limit both internal and external development, their influence increases due to the economic crisis, martial law, the search for ways to increase the level of competitiveness of the woodworking industry is becoming more urgent. This article examines the impact of investments on the innovative activity of woodworking enterprises in Ukraine. The main types of investments and their importance for the development of innovations are analyzed. It describes the current state of the woodworking industry, the main problems faced by enterprises and the potential for development. The main obstacles to attracting investment, such as political instability, imperfect legal framework and corruption, are highlighted. Based on the analysis, conclusions are drawn and recommendations are offered to improve the efficiency of investment activity and stimulate the innovative development of the woodworking industry in Ukraine.

Sobre el ejercicio y el control de la discrecionalidad
Authors: Lifante Vidal Isabel
Published: June 2024

Este trabajo ofrece una aproximación general al tema de la discrecionalidad en el Derecho, tomando como caso paradigmático el de los poderes discrecionales de la administración. En primer lugar, se plantea cómo entender la caracterización clásica de la discrecionalidad como margen de libertad para hacerla compatible con los presupuestos de un Estado constitucional de Derecho. En segundo lugar, se aborda la cuestión de en qué ocasiones existe discrecionalidad, o cuál es su origen normativo (que se vincula a la regulación de la conducta a través de las normas de fin). En tercer lugar, se plantea la cuestión acerca de cómo debe ejercerse la discrecionalidad, analizando para ello las peculiaridades de los deberes vinculados a responsabilidades. En cuarto lugar, se propone una distinción entre dos tipos de discrecionalidad (la técnica y la política). Y, por último, se analiza la posibilidad de establecer controles sobre el ejercicio de la discrecionalidad. Es en este último apartado en el que surge la cuestión de la deferencia, que en opinión de la autora ha de ser entendida como un principio regulativo del ejercicio de dicho control.
Transcriptome analysis suggests broad jejunal alterations in Linghu’s obesity-diarrhea syndrome: A pilot study
Authors: Niu Xiao-Tong , Wang Xiang-Yao , Wang Yan , Han Ke , Ru Nan , Xiang Jing-Yuan , Linghu En-Qiang
Published: June 2024

BACKGROUND

Obesity is associated with a significantly increased risk for chronic diarrhea, which has been proposed as Linghu’s obesity-diarrhea syndrome (ODS); however, its molecular mechanisms are largely unknown.

AIM

To reveal the transcriptomic changes in the jejunum involved in ODS.

METHODS

In a cohort of 6 ODS patients (JOD group), 6 obese people without diarrhea (JO group), and 6 healthy controls (JC group), high-throughput sequencing and bioinformatics analyses were performed to identify jejunal mucosal mRNA expression alterations and dysfunctional biological processes. In another cohort of 16 ODS patients (SOD group), 16 obese people without diarrhea (SO group), and 16 healthy controls (SC group), serum diamine oxidase (DAO) and D-lactate (D-LA) concentrations were detected to assess changes in intestinal barrier function.

RESULTS

The gene expression profiles of jejunal mucosa in the JO and JC groups were similar, with only 1 differentially expressed gene (DEG). The gene expression profile of the JOD group was significantly changed, with 411 DEGs compared with the JO group and 211 DEGs compared with the JC group, 129 of which overlapped. The enrichment analysis of these DEGs showed that the biological processes such as digestion, absorption, and transport of nutrients (especially lipids) tended to be up-regulated in the JOD group, while the biological processes such as rRNA processing, mitochondrial translation, antimicrobial humoral response, DNA replication, and DNA repair tended to be down-regulated in the JOD group. Eight DEGs (CDT1 , NHP2 , EXOSC5 , EPN3 , NME1 , REG3A , PLA2G2A , and PRSS2 ) may play a key regulatory role in the pathological process of ODS, and their expression levels were significantly decreased in ODS patients (P < 0.001). In the second cohort, compared with healthy controls, the levels of serum intestinal barrier function markers (DAO and D-LA) were significantly increased in all obese individuals (P < 0.01), but were higher in the SOD group than in the SO group (P < 0.001).

CONCLUSION

Compared with healthy controls and obese individuals without diarrhea, patients with Linghu’s ODS had extensive transcriptomic changes in the jejunal mucosa, likely affecting intestinal barrier function and thus contributing to the obesity and chronic diarrhea phenotypes.

Die volumenabhängige Druckbegrenzung als Maßnahme zur Konsequenzsteuerung im Wasserstofftransport
Authors: Mair Georg W. , Günzel Stephan , Bock Robert , Saul Herbert
Published: June 2024

Mit der technologischen Entwicklung werden auch die Transporteinheiten für Druckgase größer und die zu transportierenden Gase wie Wasserstoff deutlich über die lange als Standard geltenden 200 bar hinaus komprimiert. Damit steigt das Konsequenzpotenzial eines Zwischenfalls, das nun begrenzt werden soll, um die bisherige Praxis mit wenigen Zwischenfällen von den Maßnahmen für die neuen Entwicklungen extrem großer Transportdruckbehälter abgrenzen zu können. Hierzu wurde – ausgehend von einer technologisch und sicherheitstechnisch störenden Begrenzung des Volumens von Bergungsdruckgefäßen – das sogenannte Druck-Volumen-Produkt als Kenngröße und Konsequenzmaß vorgeschlagen. Um eine breit akzeptierte Abgrenzung der heute etablierten Druckgefäße gegenüber den zukünftigen Einheiten mit noch mehr Gasinhalt erarbeiten zu können, wurde eine Arbeitsgruppe bei den Vereinten Nationen eingerichtet, deren Weg zu ihrem Ergebnis „Einführung einer Obergrenze von 1.5 Mio. bar-Liter für das Druck-Volumen-Produkt von Druckgefäßen“ mit den Wasserstoff-spezifischen Einzelschritten „Grenze zwischen Großunfall und Katastrophe“, „Die Wirkung von Druckwellen auf den menschlichen Körper“, „Die Ausbreitung von Druckwellen“, „Der Referenzwert für die Bevölkerungsdichte“ und „Die Druckwellenberechnung“ hier dargestellt ist. Dieses Ergebnis der UN-Arbeitsgruppe wird bis 2027 zu einer verbindlichen Begrenzung des Druckvolumenproduktes in Druckgefäßen führen.
Der Schlüssel zur Energiewende
Authors: Schlichting Frank
Published: June 2024

Der Zubau erneuerbarer Energien führt unweigerlich zu erhöhter Volatilität in der Stromerzeugung. Diese Volatilität muss im Interesse des Stromnetzes und der Verbraucherinnen und Verbraucher ausgeglichen werden. Neben großen Solar- und Windparks braucht es verbrauchsnahe Stromerzeugung und intelligente Lastverteilung. Durch flexible Stromnutzung lassen sich Lastspitzen vermeiden und Kosten sparen. Der Schlüssel zur Energiewende liegt darin, Eigenheime und den Strommarkt dynamisch miteinander zu vernetzen – ohne dass die Endnutzerinnen und Endnutzer die ansteigende Komplexität selbst schultern müssen. Die Voraussetzung dafür ist intelligentes Energiemanagement.

Grüner Strom aus Windkraft und Solarenergie – es gibt ihn mal im Überfluss und mal gar nicht. Power-to-X-Technologien helfen, ihn zu speichern: in Form von elektrochemisch erzeugtem Wasserstoff, der bei Bedarf zum Beispiel in Brennstoffzellen rückverstromt wird. Um die Elektrolysezellen mit Gleichstrom zu versorgen, bietet sich eine modulare Lösung aus AC/DC-Wandlern an, die den Aufbau unterschiedlichster Topologien erlaubt. Das Konzept erleichtert die Wartung und wirkt sich auf die Verfügbarkeit sowie die Lebensdauer der Elektrolysestacks vorteilhaft aus.
Does sleep benefit source memory? Investigating 12-h retention intervals with a multinomial modeling approach
Authors: Berres Sabrina , Erdfelder Edgar , Kuhlmann Beatrice G.
Published: June 2024

For retention intervals of up to 12 h, the active systems consolidation hypothesis predicts that sleep compared to wakefulness strengthens the context binding of memories previously established during encoding. Sleep should thus improve source memory. By comparing retention intervals filled with natural night sleep versus daytime wakefulness, we tested this prediction in two online source-monitoring experiments using intentionally learned pictures as items and incidentally learned screen positions and frame colors as source dimensions. In Experiment 1, we examined source memory by varying the spatial position of pictures on the computer screen. Multinomial modeling analyses revealed a significant sleep benefit in source memory. In Experiment 2, we manipulated both the spatial position and the frame color of pictures orthogonally to investigate source memory for two different source dimensions at the same time, also allowing exploration of bound memory for both source dimensions. The sleep benefit on spatial source memory replicated. In contrast, no source memory sleep benefit was observed for either frame color or bound memory of both source dimensions, probably as a consequence of a floor effect in incidental encoding of color associations. In sum, the results of both experiments show that sleep within a 12-h retention interval improves source memory for spatial positions, supporting the prediction of the active systems consolidation hypothesis. However, additional research is required to clarify the impact of sleep on source memory for other context features and bound memories of multiple source dimensions.

Tanah pertanian di Subak Kerdung terindikasi mengalami pencemaran logam berat. Pencemaran tanah yang terjadi dapat disebabkan oleh penggunaan pupuk dan pestisida berlebih selama proses budidaya serta akibat kontaminan logam berat yang terkandung pada aliran air. Untuk meminimalisir kontaminan logam berat yang diserap tanaman dan tanah serta meningkatkan kesuburan tanah, diperlukan agen pembenah tanah berupa biochar. Biochar berbahan limbah pisang dapat menjadi suatu alternatif bahan bakunya karena mudah didapat dan efektif dalam menanggulangi logam berat. Penelitian dilakukan di rumah kaca, kebun percobaan Universitas Udayana dalam rentang waktu tiga bulan. Penelitian ini bertujuan untuk mengetahui efektivitas biochar limbah pisang dalam meningkatkan variabel kesuburan pada sampel tanah yang diambil dari Subak Kerdung. Penelitian tersebut menggunakan metode eksperimen, yakni rancangan acak kelompok (RAK) tersarang 2 faktor dengan 3 ulangan. Perlakuan yang dicoba adalah jenis dan dosis limbah pisang sebagai bahan pembuat biochar. Jenis limbah pisang yang digunakan terdiri atas empat taraf, yaitu biochar batang pisang (Bt), biochar kulit buah pisang (Kl), biochar tandan buah pisang (Tn), dan biochar campuran (batang pisang+ kulit buah pisang+ tandan buah pisang) (Cam) serta kontrol (tanpa pemberian biochar). Sedangkan, dosis biochar juga terdiri atas empat taraf, yaitu 0t.ha-1 (D0), 5t.ha-1 (D1), 10t.ha-1 (D2), dan 15t.ha-1 (D3). Variabel kimia tanah yang diuji meliputi C-organik, N total, KTK, kadar air, dan pH tanah. Hasil penelitian menunjukkan biochar kulit buah pisang dosis 5t.ha-1 dapat meningkatkan nilai C-organik tanah secara maksimal, biochar batang pisang dosis 15t.ha-1 dapat meningkatkan nilai N-total dan kadar air secara maksimal, dan pengaplikasian biochar batang pisang dosis 5t.ha-1 dapat meningkatkan nilai KTK secara maksimal dibandingkan dengan tanah tanpa biochar.
