Learning English is very important for student especially in the elementary school. The first important thing is to train their tongue in order they are accustomed to hear English words. The intelligence of boy students is higher than girl students. It is happened because of some factors. First, a girl is braver than a boy. Second, a girl likes to interact than a boy. The third, a girl is clever to open their mouth so appear the movement in their lips and their tongue. Thus, from those factors influence the pronunciation of a girl better than boy. The formulation of the problem of this analysis is how the phonetic transcription of pronunciation of students in the sixth grade in terms of manner of articulation in SD Negeri Bumijaya. In doing the analysis the researcher used some theories that have relation with the topic, they are language, phonology which consists of phonetics, phonemics, and manner of articulation. Psycholinguistics and sociolinguistics are part of concept used to sustain the analysis. In conclusion, gender influences pronunciation. Here there are differences pronunciation between boys and girls. Having done the analysis, the researcher concludes that 30% boy students are able in pronouncing the words and 46% girl students are able in pronouncing the words.

OBJECTIVE
It is not clear whether there is an additive effect of social factors in keeping patients with cervical spondylotic myelopathy (CSM) from achieving both a minimum clinically important difference (MCID) in outcomes and satisfaction after surgery. The aim of this study was to explore the effect of multiple social factors on postoperative outcomes and satisfaction.

METHODS
This was a multiinstitutional, retrospective study of the prospective Quality Outcomes Database (QOD) CSM cohort, which included patients aged 18 years or older who were diagnosed with primary CSM and underwent operative management. Social factors included race (White vs non-White), education (high school or below vs above), employment (employed vs not), and insurance (private vs nonprivate). Patients were considered to have improved from surgery if the following criteria were met: 1) they reported a score of 1 or 2 on the North American Spine Society index, and 2) they met the MCID in patient-reported outcomes (i.e., visual analog scale [VAS] neck and arm pain, Neck Disability Index [NDI], and EuroQol-5D [EQ-5D]).

RESULTS
Of the 1141 patients included in the study, 205 (18.0%) had 0, 347 (30.4%) had 1, 334 (29.3%) had 2, and 255 (22.3%) had 3 social factors. The 24-month follow-up rate was > 80% for all patient-reported outcomes. After adjusting for all relevant covariates (p < 0.02), patients with 1 or more social factors were less likely to improve from surgery in all measured outcomes including VAS neck pain (OR 0.90, 95% CI 0.83–0.99) and arm pain (OR 0.88, 95% CI 0.80–0.96); NDI (OR 0.90, 95% CI 0.83–0.98); and EQ-5D (OR 0.90, 95% CI 0.83–0.97) (all p < 0.05) compared to those without any social factors. Patients with 2 social factors (outcomes: neck pain OR 0.86, arm pain OR 0.81, NDI OR 0.84, EQ-5D OR 0.81; all p < 0.05) or 3 social factors (outcomes: neck pain OR 0.84, arm pain OR 0.84, NDI OR 0.84, EQ-5D OR 0.84; all p < 0.05) were more likely to fare worse in all outcomes compared to those with only 1 social factor.

CONCLUSIONS
Compared to those without any social factors, patients who had at least 1 social factor were less likely to achieve MCID and feel satisfied after surgery. The effect of social factors is additive in that patients with a higher number of factors are less likely to improve compared to those with only 1 social factor.
Political Polarization and Internal Conflict: A Cross-National Analysis Using Popular Support and Government Cohesion as Proxies
Authors: Parsons Brandon 
Published: January 2024

The study uses proxies of political polarization, popular support of the government, and government cohesion, to examine its role in explaining internal conflict and the specific types of political violence and civil disorder. The study uses panel data from 135 countries from 1990 to 2021. The research uses two econometric models, Quantile via Moments, to examine the effects of popular support and government cohesion across the distribution of internal conflict, and two-way fixed effects with Driscoll and Kraay standard errors. The two models account for heteroscedasticity, cross-sectional dependence, and autocorrelation. The study finds popular support of the government and its cohesion robustly explain internal conflict and its specific forms of political violence and civil disorder. The research also finds political polarization that reduces popular support and government cohesion influences internal conflict regardless of regime type. The variables are significant from autocratic to democratic, suggesting political polarization that reduces popular support and government cohesion can negatively affect internal conflict levels irrespective of regime. Finally, the study finds the internet has a minor mitigating impact on internal conflict, while its interaction with popular support and government cohesion slightly exacerbates internal conflict.

The experiment was performed to check the lethal toxicity of aqueous extract of Calotropis procera on Clarias gariepinus juveniles. A range finding test was done and the concentrations for the definitive tests were determined. A total of 150 African catfish juveniles of average weight 9.37±0.08g were randomly selected and distributed into four treatments in triplicates of 20mg/L, 40mg/l, 60mg/L, 80mg/L concentrations and a control (0.00) using a static bioassay test over a period of 96 hours. Behavioral responses observed during exposure of the fish to lethal concentrations included erratic swimming, air gulping, haemorrhage, loss of equilibrium and sudden death. All data obtained were summarised using descriptive statistics for the mortality, water quality parameters, growth performance and nutrient utilization. While one-way analysis of variance (ANOVA) was used to assess differences in means among the concentrations and Duncan multiple range tests was used to separate the means, where there was a difference. Physico-chemical water parameters and haematological parameters showed various significant difference among the treatments (P< 0.05). C. procera at higher concentrations of 40mg/L and above was highly toxic to fish, which led to erratic behavior and mortality.

<img src=” https://s3.amazonaws.com/production.scholastica/article/92424/large/prnano_992023ga.jpg?1705765455”> Neurodegenerative diseases (NDDs), including Alzheimer’s disease (AD), Parkinson’s disease (PD), and glioblastoma tumors (GB), represent a spectrum of disorders characterized by progressive neuronal degeneration. This gradual deterioration presents significant challenges in early diagnosis and treatment. As a solution, iron oxide nanoparticles (IONPs) have emerged as promising materials due to their diminutive size and inherent biocompatibility, which facilitates bypassing the blood-brain barrier (BBB), thereby serving as effective targeted nanocarriers for neuroprotective therapeutics, offering efficient delivery to the brain. Furthermore, IONPs demonstrate efficacy as T1/T2 contrast agents (CAs), offering a novel diagnostic tool for various NDDs, emphasizing GB. Despite the expanding potential of IONPs in the management of NDDs, a clear gap exists in developing environmentally sustainable synthesis methods. Such methods must adhere to ecological standards and enable the production of nanoparticles capable of efficiently crossing the BBB. This is essential for precisely delivering and monitoring therapeutic interventions in diseases such as AD, PD, and GB. This review systematically explores the potential of green-synthesized IONPs in the context of NDD treatment. In this review, we emphasize different functionalization techniques for IONPs, tackling how these functionalized IONPs can be effective therapeutic approaches for NDDs. Moreover, we discuss biosafety and biocompatibility by covering a range of in vitro biocompatibility studies to analyze the safety of green-synthesized IONPs for the human body. Furthermore, our thorough analysis discussed the current state of green-synthesized IONPs using plant extracts polyphenols, which also act as neuroprotective agents, as proved by studies mentioned in the review.

Published: January 2024

Introducción. En la actualidad el tratamiento endodóntico es uno de los procedimientos más efectuados en la Odontología conservadora. Uno de los pasos más importante es la desinfección de los conductos radiculares ya que, en ellos se pueden encontrar microorganismos que pueden interferir en el éxito del tratamiento. Objetivo. Analizar el efecto de distintos irrigantes en la eliminación del barrillo dentinario durante el tratamiento endodóntico mediante una revisión bibliográfica. Metodología. Estudio de base bibliográfico ejecutado mediante una búsqueda de artículos científicos sobre los irrigantes utilizados en Endodoncia, se recopiló información de bases de datos científicos tales como: Google Scholar, PubMed, Scielo, Science Direct, Elsevier, entre otros, dirigiendo el análisis a las variables tanto dependiente como independiente para desarrollar una guía sobre el correcto uso de los irrigantes endodónticos. Resultados. Se revisaron 80 artículos para analizar el efecto de diversos irrigantes en la eliminación del barrillo dentinario durante el tratamiento endodóntico, se seleccionaron 57 artículos que cumplieron con los criterios de inclusión. La mayoría de las publicaciones fueron de tipo cualitativo y descriptivo publicados entre 2019 y 2022, provenientes principalmente de Estados Unidos. La distribución por base de datos fue de la siguiente manera: Pubmed 54.2%, Google Scholar (3.4%) y a Korea Med (3.4%). El 27,45% de artículos correspondieron al cuartil Q1. Con respecto al promedio de conteo de citas y el factor de impacto SJR se encontró que en 2018 se registraron 42 citas con un factor de impacto SJR de 1.14 representando al más elevado. Conclusión. Se concluyó que cada irrigante cumple una función específica, en la actualidad no existe una única sustancia que cumpla idealmente con la eliminación de tejido orgánico, inorgánico y microrganismos presentes en los conductos, por ello, se determinó que la irrigación debe ser una combinación de los irrigantes de manera intercalada para desinfectar.

Authors: Abad Cordero Doris Stefania , Reinoso Ortiz Silvia Alexandra , Cedeño Zambrano Dolores Aracely , León Velastegui Manuel 
Published: January 2024

Introducción. La elevación de margen profundo (DME) es una alternativa menos invasiva que el alargamiento coronario y la extrusión ortodóntica, ofreciendo menor de costo y tiempo clínico. Implica elevar el margen de cavidades subgingivales para mantener la salud periodontal y prevenir la acumulación de bacterias. Considerar una distancia mínima de 3 milímetros entre la cavidad y la cresta ósea. La elección del material y el sistema adhesivo juega un papel importante en la adaptación marginal. Los compuestos de resina fluida se destacan en la adaptación marginal, aunque no son adecuados para cargas termomecánica, lo que sugiere por compuestos precalentados. Objetivo. Analizar la integridad marginal y el estado periodontal de los materiales utilizados para DME. Metodología. Este estudio es una revisión sistemática que sigue las normas de PRISMA. Se realizaron búsquedas exhaustivas en múltiples bases de datos hasta julio de 2023 y se aplicaron criterios de inclusión que se centraron en estudios que incorporaron la técnica DME. Se identificaron 692 artículos, de los cuales 23 cumplieron con los criterios de inclusión y fueron analizados en detalle. Resultados. Abordar lesiones de caries proximales subgingivales con DME para mejorar la adaptación y la salud periodontal de los tejidos circundantes. Se discuten diversos materiales utilizados para la DME, pero persiste la falta de consenso sobre la elección del material y la técnica. Se observa una controversia en estudios que evalúan la influencia de la DME en la adaptación marginal. Además, la importancia de mantener una distancia adecuada entre el margen de la restauración y la cresta ósea para la salud periodontal. Conclusión. La DME muestra una buena adaptación en condiciones de laboratorio y puede ser útil en situaciones de acceso limitado bajo las encías. La reacción de los tejidos periodontales al DME aún no está clara, por lo tanto, el impacto del DME sobre el periodonto sigue sin ser concluyente. Área de estudio general: Odontología.

A survey conducted in the ginger growing areas of Thrissur and Palakkad districts of Kerala, during 2013 and 20 14, revealed the presence of three species of flies infesting both healthy as well as diseased ginger rhizomes. The predominant, most injurious one was identified as Mimegralla sp. nr coeruleifrons (Macquart) (Diptera: Micropezidae). The biology of the same was studied in the laboratory on diseased ginger rhizomes. The mean incubation period was 3.75 days, while the mean duration of first, second and third larval instars was 2.25, 3.15 and 6.70 days respectively. The mean pupal period lasted for 8.80 days. The longevity of adult male and female flies was 43.90 and 51.00 days respectively, and the sex ratio was 1:1. The morphometric observations of each life stage are also described, with a note on the taxonomy of the fly.
New evidence of pseudo scorpion Ellingsenius indicus Chamberlin as predator of Indian honey bee Apis cerana F.
Authors: Sharma S. D. , Ramesh Lal 
Published: January 2024

Traditional wall hives in the two villages of Kullu district, Himachal Pradesh namely Bhindi and Daula, recorded a heavy mortality of Indian honey bees (Apis cerana) due to the attack of an arachnid predator identified as a pseudo scorpion Ellingsenius indicus. It was observed that the pseudo scorpions did not venture the comb full of bees but attacked only those bees which were either moving in isolation or in groups of 1-3 or those coming and going to the hive entrance for foraging. There was a complete loss of bees in three colonies whereas in other two colonies more than 70% of worker mortality was noticed. The observations recorded from the wall hives as well as from the laboratory experiments, revealed that generally 1-3 pseudo scorpions (E. indicus) caught hold of the single bee preferably from its legs and sometimes from its wings and did not leave the bee from their grip so long it was not dead.
