A Simple Cyst of the Testis was Found Incidentally during Castration for Prostatic Cancer
Authors: Tachibana Mitsuhiro , Hamayasu Hideki , Nakagawa Hiromichi , Nozawa Hayato , Fukuzawa Shigeki
Published: October 2023

Simple cysts (SCs) within the testes are rare in adults. The testicular SC lining comprises mesothelial cells. This report presents a case involving the accidental discovery of a castration-worthy SC in the right testis of a Japanese man in his 90s who was diagnosed with prostatic adenocarcinoma. Microscopic analysis revealed that the cystic wall was covered with flat to cuboidal mesothelial cells. Immunohistochemistry demonstrated mesothelial cell positivity for calretinin, Wilms tumor 1 (WT-1), Hector Battifora mesothelial epitope-1 (HBME-1), and cyclin-dependent kinase inhibitor p16 (p16INK4a). Notably, no human papillomavirus (HPV) in situ hybridization was detected. This report outlines an exceptionally rare instance of a simple cyst within the testis, suggesting the possibility of its origin from ectopic rete testis epithelium. This marks the inaugural documentation in the English literature of an SC within the testis found incidentally during castration for prostatic cancer.
Empowering India's Scheduled Castes: Challenges, Reservations, and Pathways to Progress"
Authors: Gupta Mayank
Published: October 2023

This paper examines the condition of the Scheduled Castes in India and recognizes the factors that are causing dismal performance of the Scheduled Castes despite reservation policies. The paper first discusses the condition of Scheduled Castes based on the parameters of social, economic, education, and political representation. It then provides a brief overview of the current reservation percentages allocated to Scheduled Castes in various sectors. Moreover, the paper explores the causes for the dismal performance of Scheduled Castes despite the existence of reservation policies. In order to improve the condition of Scheduled Castes, the paper proposes a multifaceted approach, including the consideration of socio-economic criteria for recognizing castes in the list of Scheduled Castes, dis reservation of affluent Scheduled Caste families, preferential appointment of Scheduled Castes in administrative positions within Scheduled Areas, and reforms within the National Commission for Scheduled Castes. The paper also emphasizes the importance of periodic evaluations of socioeconomic conditions, talent identification, and grassroots awareness campaigns as strategies to uplift the Scheduled Castes.Keywords
Greening Development: Reducing Urban Tree Canopy Loss through Incentives
Authors: Willis Elise , Koeser Andrew , Clarke Mysha , Hansen Gail , Hilbert Deborah , Lusk Mary , Roman Lara , Warner Laura
Published: October 2023

Development and redevelopment are important drivers of tree removal and canopy loss in urban landscapes. Local ordinances are often used to curtail tree removal, but punitive regulations alone may not be enough to reduce urban tree canopy loss in land development. In Florida (US), efforts to balance trees and development have so far focused on fees and fines, but with a recent backlash against tree regulations and the fast pace of urban growth, we explored the possible role of incentives in urban tree policies. We interviewed 20 land developers across Florida to understand their perspectives on current barriers and potential incentives for tree preservation and planting. We collected data from developers, whose perspectives on tree preservation are often unknown or overlooked, despite their significant role in tree planting, removal, and retention in and around cities. Our results show that major barriers to tree preservation and planting include requirements to grade sites for stormwater management, site constraints, and monetary costs. Most developers did not know of any existing incentives beyond intrinsic motivations but said that financial incentives would be most appealing to them. Top incentive suggestions include increasing building density, reducing impact fees and tax liability, and changing tree mitigation policies. Another promising finding is that developers are willing to work with regulators to find solutions that benefit both parties. Future research should consider evaluating the level of support and viability of different incentives by gathering feedback from policymakers, land developers, and the public.

Published: October 2023

Gold nanoclusters (AuNCs) with fluorescence in the Near Infrared (NIR) by both one- and two-photon electronic excitation were incorporated in mesoporous silica nanoparticles (MSNs) using a novel one-pot synthesis procedure where the condensation polymerization of alkoxysilane monomers in the presence of the AuNCs and a surfactant produce hybrid MSNs of 49 nm diameter. This method was further developed to prepare 30 nm diameter nanocomposite particles with simultaneous NIR fluorescence and superparamagnetic properties, with a core composed of superparamagnetic manganese ferrite nanoparticles (MnFe2O4) coated with a thin silica layer, and a shell of mesoporous silica decorated with AuNCs. The nanocomposite particles feature NIR-photoluminescence with 0.6% quantum yield and large Stokes shift (290 nm), and superparamagnetic response at 300 K, with a saturation magnetization of 13.4 emu g-1. The conjugation of NIR photoluminescence and superparamagnetic properties in the biocompatible nanocomposite has high potential for application in multimodal bioimaging.

Knowledge-Based Prioritization of Genomic Variations: A Quest for Detailed Understanding the Genetic Architecture of Diseases
Authors: Iourov Ivan Y.
Published: October 2023

Understanding the genetic architecture of a disease is crucial for development of valid diagnostic and therapeutic interventions. The analysis of genomic variations associated with pathological conditions is the starting point for uncovering disease-causing pathways (candidate processes). However, the complexity of intergenic and genetic-environmental interactions hinders the identification of pathogenic values of genomic changes. Furthermore, heredity, epigenetics and somatic mosaicism make the interpretation of genomic data even more sophisticated. To succeed, a variety of bioinformatic techniques are applied. Here, reviewing own and literature data, knowledge-based prioritization of genomic variations is described. Theoretical basis of the knowledge-based prioritization is given with a special regard to gene ontology, heuristics, hermeneutics (genomic hermeneutics) and analytics. Practical and methodological issues of prioritization using ontology- or pathway-based systems analysis are considered in the light of optimistic and realistic scenarios of cumulative phenotypic effects of the variome (the whole set of genomic variations in an individual or specific set of genomic variations for a phenotypic outcome). In the present communication, copy number variants (CNVs) in children with neurodevelopmental diseases are used as a practical foundation for the prioritization, inasmuch as these genome variations are systematically overlooked in the so-called NGS era. Nonetheless, it is highly likely that the prioritization is applicable to almost all types of genomic variations (e.g. chromosome abnormalities, gene mutations, functional synonymous variants etc.). The present methodology seems to be a valuable addition to current biomedical science widening the opportunities for medical genomics and genetics.

The aim of this study was to further understand the histomorphometry of seminiferous tubules from local goat testicles that were fixed with different fixatives. Nine testicles were randomly chosen, each fixed with 10% formalin, 10% neutral buffered formalin (NBF), and 4% paraformaldehyde (PFA) solutions. The sample was then proceeded to histology preparation and stained with haematoxylin eosin (HE). Observation of the tissue was carried out using microscope and the data obtained was analyzed statistically. The results showed that there was a significant difference (P0.05) on each fixative in tubular diameter and membrane, and very significant difference (P0.01) on germinal cell and staining absorbability. Duncan test result on tubular diameter showed that the use of PFA fixative was significantly different (P0.05) compared to formalin fixative while the use of NBF fixative had no significant difference (P0.05) compared to PFA fixative. In addition, the measurement of interstitial membrane of seminiferous tubules showed no significant difference (P0.05) among three fixatives. To conclude, formalin, NBF, and PFA fixatives affect seminiferous tubules, basal membrane structure, and germinal cell appearance inside tubular lumen. Type of tissues and fixative must be considered in selecting the suitable fixative.

This study aims to determine the content of secondary metabolites, antibacterial activity, antilarvicides, and pulutan leaf acetone extract toxicity test. Photochemical tests were carried out using several suitable reagents. Bacterial activity test using disc diffusion and microdilution methods against Salmonella typhi and Streptococcus mutans bacteria, then toxicity test using the BSLT method. Larvicide test by observing the mortality of Aedes aegypti larvae for 24 hours. Based on the phytochemical tests, pulutan leaves contain flavonoids, alkaloids, steroids, saponins, and tannins. The results of the antibacterial activity test showed activity against S. typhi and S. mutans with inhibition zone diameters of 7.05 mm and 8.25 mm, respectively. The Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) values against S. typhi and S. mutans were 5000 g/mL and 5000 g/mL, respectively. The toxicity test results of pulutan leaf acetone extract had an LC50 value of 37.20 ppm, while the results of the larvicidal activity test had an LC50 value of 1971.19 ppm. The toxicity test results showed that the acetone extract of pulutan leaves was toxic and not anti-larvicidal to A. aegypti larvae. The bioactivity ability of pulutan leaf acetone extract is influenced by the content of flavonoids, alkaloids, steroids, saponins, and tannins. It can be concluded that the pulutan leaf extract in the Nias area has the potential as a source of antibacterial compounds

The samples in this study were 66 quail eggs which were divided into two groups, the first group (33 eggs) was stored at 27oC, and the second group (33 eggs) was kept at 5oC. This study used a completely randomized design with two factors, temperature and storage time. The observation was carried out on days 1, 7, 13, 19, 25, and 31 with triplicates. The parameters used in this study were air sac height, egg yolk index, white egg index, and Haugh Unit (HU). This study showed that temperature and storage time affected the quality of quail eggs. Eggs stored at 27oC showed a quality decrease indicated by higher air sac position, and lower egg yolk index and egg white index. Eggs kept at 5oC showed no significant degradation. The HU for both groups ranged between 76-81 which implied that the eggs had AA quality even after 31 days of storage.

Candy is a product made from sugar which can cause health problems. The proportion of sugar with high calories can be replaced with isomalt which is low in calories, and honey which is beneficial to health. In addition, the use of synthetic flavours in candy can be replaced with essential oils such as patchouli oil. Product analysis was in the form of salivary bacterial growth inhibition and hedonic organoleptic tests to determine the samples' antibacterial activity and sensory characteristics. This research was conducted using two factors of a sugar formulation consisting of 3 levels, namely, G1, G2, and G3. The second factor was patchouli oil concentration consisting of 4 levels, namely N1, N2, N3, and N4. Data on the results of the antibacterial and hedonic activity tests were analyzed using a factorial, Completely Randomized Design (CRD). From the analysis of variance, it can be concluded that sugar formulation, patchouli oil concentration, and their interactions had a significant effect (P0.05) on the growth of salivary bacteria, patchouli oil concentration had a significant effect (P0.05) on hedonic aroma, sugar formulation had a significant effect (P0.05) P0.05) on hedonic texture and had no significant effect (P0.05) on hedonic colour and taste. The best treatment was obtained from the G2N2 sample with salivary bacterial growth of 34.50 ± 6.02 colonies and an overall hedonic value of 3.05 (likes).

Betta fish (Betta splendens) are one of the most popular ornamental fish due to their gorgeous colors and various shapes. This study aimed to find pathogenic bacteria in betta fish (Betta splendens) in fish farm in Bogor. Body swabs were collected from four decorative betta fish, and from tank water. Two of the fish were dead and two of which were exhibiting symptoms of disease. Bacterial isolation was performed on multiple agar media, and bacteria were identified based on the growth characteristics of the colonies, Gram staining, and biochemical testing. The results of the analysis revealed the presence of 16 bacterial isolates, including Edwardsiella sp., Escherichia coli, and Vibrio sp. from dead fish, whereas Citrobacter sp, Providencia sp, and Vibrio sp were detected in diseased fish. In aquarium water, Escherichia coli, Citrobacter sp Proteus sp and Providencia sp. were detected. Betta fish are susceptible to suffer from diseases if the water quality is low since maintaining and enhancing the health of betta fish is highly dependent on water quality.

Reducing emissions at each step of the Oil & Gas Value chain is needed to help meet the global goal of keeping the temperature increase below 1.5C° of preindustrial level. This paper presents a method to calculate emissions and optimize operations to reduce emissions at the well planning stage.

Three specific rigs were chosen and the data from their operations and the diesel consumption over the last 18 months (about 1 and a half years) was used to build a model that links specific operation on the rig with its associated emissions. Part of the data was used for model building while the rest was used for model verification. The energy consumption of each piece of equipment on the rig was also used in the calculations to document their wattage. An optimization tool is developed to help optimize rig operations for emissions reduction by choosing the proper rig and the rest of the equipment.

The diesel usage data was lower resolution (one data points per day) compared to the operations (hourly). So, the model development was particularly challenging. It was found that there is considerable room for energy optimization especially with regards to the use of diesel generators. A considerable amount of excess energy is produced which gets wasted. Also, the cementing and casing has the greatest impact on the emissions as both materials emit a huge amount of carbon. Optimization of the emissions on the well planning stage is much more effective than emission reduction strategies post planning as the room for optimization is significantly less.

Our approach is based on state-of-the-art deep reinforcement learning (DRL) and data science techniques that have been proven to work on complex systems that have different inputs. DRL trains an algorithm with a reward system that supplies positive and negative feedback (degree of emissions) to an Artificial Intelligence (AI) agent for performing actions. These actions are the various strategies in rig operations the agent takes to reduce emissions, the lower the emissions the higher the rewards for the agent. In iterative process the agent narrows down the best policy (plan) for each rig that lowers the emission.

The use of data science and machine learning in well planning for emissions reduction is a novel approach with expert feedback being constant in our methods. Using DRL (deep reinforcement learning) to quantify emissions in well planning is a revolutionary technique. It is the first time in the industry that DRL is being used to assist in emissions reductions from upstream activities. We bring technology that has redefined the capabilities of AI in a variety of applications, including reservoir optimization and complex decision-making systems.

Despite of more than three decades of operations in the Gulf of Mexico area, still undesirable events and subsequent nonproductive time (NPT) is observed during daily operations. Being an environment under a high-cost operation, the proper risk identification, prevention, control, and mitigation is a key component for the success of the project. The objective of this document is to describe the implementation of an integrated risk management process, covering all the lifecycle process of the project including design, execution, and evaluation.

Integrated Risk management strategy includes the evaluation of the readiness of the resources required for the project execution, such as: equipment, personnel, logistics, and facilities. The process started with a long-term planning review, including a detailed identification of critical activities for each individual well plan during the project lifetime. Historical definition of undesirable events, incorporating proper statistical analysis and quantification of the NPT complement the detailed planning risk definition stage. Further quantification of impact was established, to define the baseline for the project. In addition, the model includes the inputs of subject matter experts in different areas, to define the prevention and control measures, looking to reduce the severity over the project execution. The execution stage is supported by the early identification of deviations compared to parameters previously established and is tackled with the application of digital solutions. To close the operations cycle, the systematic knowledge sharing process, live lessons learn capture, and constant re-assessment of the initial risk matrix, facilitates the identification and focus during drilling operations, supporting the learning curve.
