Diagnostic methods for Helicobacter pylori infection
Authors: Rodríguez Sicilia MJ 
Published: July 2023

Resumen

Actualmente existen distintos métodos para realizar el diagnóstico de la infección por Helicobacter pylori, sin embargo, no existe consenso oficial sobre el test óptimo para el diagnóstico, por lo que la elección se debe realizar en base a distintos factores. Uno de los factores que influyen en la elección del método diagnóstico es la necesidad o no de realizar gastroscopia para evaluar los síntomas o para seguimiento de patología digestiva existente, en función de esto se realizará un test diagnóstico invasivo o no invasivo. También influye la finalidad con la que el test se realiza: diagnosticar infección activa por H. pylori, comprobar la curación de la infección tras tratamiento erradicador o determinar la sensibilidad de la bacteria a los diferentes antibióticos tras fracaso de tratamiento erradicador previo. Otros determinantes que influyen son la prevalencia de la infección por H. pylori en la población, situaciones que produzcan reducción de la población bacteriana en la mucosa gástrica, como la presencia de sangrado digestivo activo o el uso reciente de ciertos fármacos (inhibidores de la bomba de protones, antibióticos, bismuto), la disponibilidad y coste del test.

La siguiente revisión pretende dar una visión general sobre los avances más recientes en los métodos diagnósticos para evaluar la infección por H. pylori y su interpretación, por lo que es necesario conocer las indicaciones precisas de cada test diagnóstico, conociendo sus ventajas y posibles defectos, así como los distintos escenarios en los que nos podemos encontrar sabiendo elegir el test diagnóstico más adecuado en cada situación.

Resumen

Los tumores neuroendocrinos (TNE) son un grupo heterogéneo de neoplasias que difieren en comportamiento biológico, apariencia histológica y respuesta al tratamiento. La mayoría presentan un crecimiento lento y una evolución benigna. Sin embargo, un pequeño grupo de tumores presentan un crecimiento más rápido, son más agresivos y se encuentran avanzados cuando se diagnostican. Un porcentaje elevado de este pequeño grupo son tumores de primario desconocido y a menudo se presentan como metástasis hepáticas para posteriormente identificar el primario en el tracto gastrointestinal o en el páncreas. En estos tumores, es importante realizar un estudio completo que incluya pruebas de imagen, estudio endoscópico, marcadores tumorales, receptores de somatostatina y niveles urinarios de ácido 5-hidroxiindolacético. En función de la situación clínica se optará por tratamiento quirúrgico y/o radioterápico.

Published: July 2023

Cancer is one of the types of genomic diseases. It is caused by pathogenic mutation in the Genome inside a cell so that the cell can be activated to divide & grow uncontrollably. The key objective of this study is to verify that the actual causative agent of the disease cancer is the pathogenic mutation in Genome. The contents of Figures displayed are designed to serve as Results in the targetful strategy of this study. The actual causative agent of cancer and the precancerous effects of risk factors of cancer are identified and made available in order to have strong conclusive statements. Cancer occurs if and only if Cancerous Genome synthesizes enormous number of autoinfected (cancered) cells rapidly by way of apoptosisless and uncontrolled growth of cancered cells involving fast cell division, using its chemical energy-containing nutrients as raw materials; otherwise, none of the precancerous effects of risk factors of cancer can cause the occurrence of cancer.
Analytical Overview of Some Motivational Theories and Their Implications in Provision of Continuous Professional Development of Staff of Colleges of Education and Analogous Institutions
Authors: Atiku Benedicta Awusi 
Published: July 2023

Motivation is the fuel in the engine of all living things in energizing for work to be done. If ignored, sectors are bound to run into mediocrity and subsequent diminishing returns in productivity. The sector of education needs that vitamin called motivation more than any other sector. Colleges of Education in Ghana by Act 847, produce teachers to implement basic school curriculum of the country. The competence of teachers produced by these Colleges depends largely on the complex element of motivation as catalyst for good work in training student teachers. This paper dilates the topical issues of motivation in provision of continuous professional development for staff of the Colleges of Education as a way of improving work in that sector of education and related in the country. The paper presents motivational activities in organism using the author’s construct, Atiku 2018 SGT-AFGTF Model. This is followed by presentation on analytical overview of some content and process motivational theories. Every analysis, its implications to the Colleges of Education system are presented. The conclusion to the discussions is that motivation is universally needed by all sectors of workers and that though some packages seem to be needed by all workers, individual differentiated needs need to be taking into consideration when considering motivation of various sectors to boost performance. It is recommended, among others, that monetary packages should cover all workers and all sectors should be provided with opportunity to upgrade.

Ce travail avait comme objectif d’identifier les remèdes au problème dû à la mauvaise application du béton armé dans la construction des immeubles en ville de Goma. Pour y arriver nous avons utilisé la méthode Analytique et descriptive. Après analyse des données nous avons observé les résultats suivant : L’utilisation de machine vibreur à béton devra entrer dans la culture de fabrication pour obtenir un béton compact. Les armatures à placer dans une pièce en béton armé doivent être calculées. La bonne disposition constructive des armatures dans une pièce en Béton Armé doit accompagner le calcul du ferraillage. À Goma, il faut faire attention aux diamètres, de barre ainsi qu’à leurs longueurs ; facilement les barres vendues de diamètre 12mm ont 10mm de diamètres mesuré au pied à coulisse et 10 m de longueur au lieur de 12m. Il faut donc vaincre le sous dimensionnement en choisissant la section immédiatement supérieure à cause de la qualité et section douteuses de l’acier. Les intervenantsLes services étatiques qui ont le contrôle de conformité dans leurs attributions doivent renforcer leur contrôle pour que les producteurs des matériaux du béton armé puissent rassurer les constructeurs. Aussi, les constructeurs formés doivent faire preuve de technicité et de responsabilité en supervisant les travaux aux chantiers. De même, les maitres d’ouvrages doivent cesser de confier leurs travaux aux individus non qualifiés, tout simplement parce qu’ils sont moins disant. Voilà quelques remèdes à apporter pour les erreurs dues à la mauvaise application du béton Armé dans la ville de Goma

The purpose of this study is to identify the implementation of management standard policies in quality assurance for Madrasah in Cianjur Regency. The approach used is descriptive qualitative with research techniques of observation, interviews, and documentation studies. Data collection was carried out through orientation, exploration, and member checks. The results showed that the implementation of madrasah management and quality assurance standards were quite optimal. It could be seen from the activities of planning programs, implementing programs, conducting program monitoring and evaluation as well as implementing effective leadership, constraints and solutions. Madrasas are quite capable of implementing management standards correctly although there are still many shortcomings, including, routine management activities, formalities, low awareness of the importance on quality, lack of regulation understandings, finance activities, and availability of facilities-infrastructure. The madrasas are respectively pesantren-based strategic places, collaboration ability to involve with the community, principal’s effective leadership, and high enthusiasm to improve the madrasah’s quality through implementing education management standards.Keywords: implementation; education management standards; madrasa quality

Published: July 2023

Abstract
Dwarf galaxies located in extremely underdense cosmic voids are excellent test beds for disentangling the effects of large-scale environments on galaxy formation and evolution. We present the first results of the Dwarfs in Void Environments Survey, which has obtained integral field spectroscopy for low-mass galaxies (M

⊙) located inside (N = 21) and outside (N = 9) cosmic voids using the Keck Cosmic Web Imager. Using measurements of stellar line-of-sight rotational velocity v
rot and velocity dispersion σ
⋆, we test the tidal stirring hypothesis, which posits that dwarf spheroidal galaxies are formed through tidal interactions with more massive host galaxies. We measure low values of v
rot/σ

rot/σ
⋆ and galaxy stellar mass, perhaps implying that stellar disk formation depends on mass rather than environment. Although some of our conclusions may be slightly modified by systematic effects, our main result still holds: that isolated low-mass galaxies may form and remain as puffy systems rather than the dynamically cold disks predicted by classical galaxy formation theory.
Cosmic Rays Self-arising Turbulence with Universal Spectrum −8/3
Authors: Chefranov Artem S. , Chefranov Sergey G. , Golitsyn Georgy S. 
Published: July 2023

Abstract
In the inertial subrange of scales, an exact compressible turbulence universal spectrum law −8/3 for the density fluctuations of cosmic rays (CRs) in the frame of the known two-fluid model of CR dynamics is obtained. It is shown that the origin of this scaling law may be due to the arising of shocks at the breaking of the nonlinear simple waves of CRs near the scale of their Larmor’s radii, as it is well known for the solar wind with the same turbulent spectrum law −8/3. The consistency of the turbulence spectrum −8/3 of CRs with the observed nonthermal differential energy distribution of CRs with a similar index −8/3 due to the possibility of self-reacceleration of the CRs on the self-arising shocks is stated. The turbulent diffusion mechanism for the observed CRs energy spectrum breaks is considered.
Interstellar Bow Shocks around Fast Stars Passing through the Local Interstellar Medium

Published: July 2023

Abstract
Bow shocks are produced in the local interstellar medium by the passage of fast stars from the Galactic thin-disk and thick-disk populations with velocities V
* = 40–80 km s−1. Stellar transits of local H i clouds occur every 3500–7000 yr on average and last between 104 and 105 yr. There could be 10–20 active bow shocks around low-mass stars inside clouds within 15 pc of the Sun. At local cloud distances of 3–10 pc, their turbulent wakes have transverse radial extents R

Published: July 2023

The snail Trochita trochiformis is a mollusk captured on the coasts of Jalisco and Guerrero of the Mexican Pacific. Despite its importance in artisanal fisheries, information on its population parameters is still being determined. This research aimed to determine the diameter-weight relationship, sex ratio, cohorts, and growth of this species. Specimens were captured from October 2019 to September 2021. Shell diameter (Sd), total weight (Tw), and the sex of the organisms were gathered from a total of 1763 females and 956 males. The sex ratio was 1.84:1, and the X2 test (P < 0.05) indicated significant differences. The Sd-Tw relationship for females and males was potential-type. The values of the allometry coefficient for both sexes were b = 2.61, b = 2.60 for females, and b = 2.62 for males. In all three cases, the t-Student test indicated negative allometric growth, which indicates that the species first grows in shell diameter, then in body weight. The ANCOVA did not show significant differences in the Sd-Tw relationships between sexes (P = 0.902). The Kolmogorov-Smirnov test applied to the Sd data showed differences between sexes (P < 0.001). In females, differences were observed in 71.5% by monthly comparisons, while in males, differences were found in 58.1%. Multinomial analysis showed three modal groups and 14 individual cohorts for both females and males. Case 2 of the Schnute model was the best for females (wi = 0.39) and males (wi = 0.53), showing sigmoidal Gompertz-type growth. The resulting growth curves showed that females exhibit accelerated growth concerning males and that both sexes reach their maximum size, 88.04 and 86.23 mm, respectively, at approximately 10 years of age.
