Entre resoluciones y realidades: descifrando Palestina en su andadura inicial (1948-1973)
Authors: Vilar-García María José
Published: April 2024

El periodo entre 1948 y 1973, marcado por la creación de Israel y la Guerra de Yom Kippur, desempeña un papel crucial en el prolongado conflicto Palestina-Israel, denominado la "Cuestión de Palestina". Esta época estableció los cimientos de una crisis prolongada y desestabilizadora en el siglo XX. El conflicto, originado con la formación de Israel, ha resultado en represión, exilio y ocupación, generando alienación en los no integrados al Estado hebreo. A pesar de ello, la supervivencia de Israel es considerada un derecho incuestionable respaldado por la ONU, reconociendo su presencia en tierras ancestrales. El entendimiento entre árabes e israelíes, crucial para la paz e interés internacional, se ve afectado por factores como presiones externas, especialmente de Estados Unidos, dinámicas políticas internas en Israel y divisiones en el mundo árabe y entre los palestinos. Este periodo sentó las bases de tensiones persistentes en la región.

Published: April 2024

Background: The incidence of pertussis is increasing every year, especially in developing countries. Low immunization coverage and decreased immunity are some of the factors causing the re-increase in pertussis cases. The protection provided by the pertussis vaccine whole and acellular pertussis given as a baby will decrease with age. This study aims to determine the difference in mean levels of anti-pertussis antibodies in children who received acellular pertussis and whole pertussis immunization without a booster. 
Methods: A cross-sectional study was carried out at the pediatric polyclinic of Dr. M. Djamil General Hospital Padang from December 2022 to December 2023. Research subjects were children aged 5-9 years with a history of whole pertussis immunization (DPwT) 3 times or acellular pertussis immunization (DPaT) 3 times. The research subjects were examined for anti-pertussis antibody titers using the ELISA technique.
Results: Thirty-four children with a history of DPwT immunization 3 times and 34 children with a history of DPwT immunization 3 times were research subjects, with mean age 6.94±1.49 in the DPwT group and 6.88 ±1.61 in the DPaT group. The mean anti-pertussis antibody level in the DPwT group (9.54 IU/mL) was higher than the DPaT group (6.96 IU/mL) but was not statistically significant (p>0.05). The average antibody results showed that the antibody levels in both groups were below the antibody titer threshold that provides protection against pertussis. The results of the analysis showed that there was a significant difference in the incidence of AEFI between the DPwT and DPaT immunization groups (p<0.05).
Conclusion: There was no difference in anti-pertussis antibody levels in children who received DPwT and DPaT immunization 3 times. Pertussis immunization is a required booster so that antibody levels are sufficient to provide protection against pertussis.

Authors: Minanti Nanda Anessa , Yusri Dianne Jurnalis
Published: April 2024

Background: In adults, portal hypertension is generally caused by hepatic cirrhosis, whereas in children it is more commonly caused by extrahepatic abnormalities with normal liver function. Portal hypertension causes hemodynamic abnormalities. Gastrointestinal bleeding is the most severe clinical manifestation of portal hypertension in both children and adults. Pathogenetically, increased pressure in the portal vein can be caused by increased vascular resistance and increased portal blood flow. The site of obstruction can be prehepatic (portal vein obstruction), intrahepatic (presinusoidal: eg congenital hepatic fibrosis; para sinusoidal: cirrhosis, hepatotoxic drug therapy, vitamin A hepatotoxicity; post sinusoidal: venocclusive disease) and/or post hepatic (Budd-Chiari syndrome, constrictive pericarditis).
Case presentation: The study reports the results of observations of a case of a boy, FAA, aged 12 years and 2 months who came to the emergency room at Dr. M. Djamil General Hospital Padang with the main complaint of hematemesis and splenomegaly from physical examination. Non cirrhotic portal fibrosis is a cause  that is not uncommon in the population in the early second decade of life. Some children with non-cirrhotic portal fibrosis as adults can end up with end stage liver disease.
Conclusion: Patients with noncirrhotic or cirrhotic portal hypertension can be assessed using the Child Pugh instrument as an instrument that is still used to determine the survival rate if patients with portal hypertension.

Authors: Arif Hidayat  , Saptyaji Harnowi
Published: April 2024

Sugar producers can extend their sugar companies by expanding into non-sugar products. A sugarcane-based company that focuses on product diversification is electricity generation from bagasse. As the principal energy source, the cogeneration system progressively creates two distinct forms of energy (mechanical energy and thermal energy). Krebet Baru 2's sugar factory has a capacity of 5,200 TCD. Under some conditions, it can generate up to 1.5 MW of additional Power. This research aims to investigate the link between capacity and cogeneration efficiency. As a result, extra electricity may be generated forever. According to the data, capacity did not influence cogeneration efficiency. Excess Power may be acquired by optimizing steam usage, assessing inefficient energy sources, and utilizing high-pressure steam production facilities.

Authors: Purnata Hendi , Hera Susanti  , Sugeng Dwi Riyanto  , Agus Santoso
Published: April 2024

Indonesia has the potential of sea wave energy with the second largest coastline having a density of up to 20 kW / m2. Currently, the use of sea wave technology is still at the prototype stage, with several weaknesses such as erratic sea waves, tides and ocean currents so that they can affect the power generated in ocean wave energy. The results of ocean wave energy in mechanical arrays cannot be utilized because of erratic waves. The higher the wave, the greater the power generated and vice versa. If this problem is not resolved, it can cause unstable power output and cause damage to electronic equipment. The solution to this problem is to modify the DC-DC buck boost converter circuit using  the  Hyeteresis band method, which limits  voltage  surges below or above to produce the desired voltage in  order to maintain constant power and as energy for storage in the storage system.   The result  of  this study  is that the performance of DC generators in producing voltage is greatly influenced by speed. At low speeds, the voltage produced by the generator is still too low to charge the battery or in other words  cannot be in  a perfect charging position, while at maximum speed it produces voltage with Achieve a level sufficient for battery charging. Therefore, control and adjustment of generator speed is key in maximizing battery charging efficiency using a buck-boost converter.

In the learning process, the material is only in videos and power points about fire prevention and control. Conversely, students more easily understand contextualized material. One of them is an automatic fire extinguisher simulation. This simulation uses a fire sensor as its input, Arduino uno as its control, and a relay as an output from Arduino. This learning media was tested on 40 people with backgrounds as students and employees. Based on the results of this learning media trial, the average questionnaire assessment reached 87.6%, so this learning medium is effective as a learning medium for fire extinguisher simulation.
Food protein-induced enterocolitis syndrome in adults: review and practice recommendations
Authors: González-Delgado Purificación , Entrala Ana , Nuñez-Orjales Ramon , Marchan Eva , Fernández Javier , Nowak-Wegrzyn Anna
Published: April 2024

Food protein-induced enterocolitis syndrome (FPIES) is an allergic disorder that manifests as reproducible gastrointestinal symptoms within hours of ingestion of the causative food, which can progress to dehydration and hypotension. Historically, FPIES has been recognized as a disease affecting the pediatric population but it can also develop de novo in adults. The pathophysiology is not well understood; however, the local adaptive immune system and gene expression linked to innate immune activation are implicated. Adult-onset FPIES has some differences with pediatric FPIES. Vomiting may be absent, while abdominal pain is the most common manifestation. A clear predominance in women occurs, being seafood the most common trigger, although many other foods have also been implicated. Diagnosis of adult-onset FPIES is based on a thorough clinical history but in many cases, it should be followed by an oral food challenge (OFC), due to the absence of vomiting in some patients and the lack of confirmatory diagnostic test. The first-line treatment for acute FPIES reactions is fluid replacement, by the oral route in mild to moderate reactions or via the intravenous route in severe reactions. Ondansetron may be effective in shortening the duration of emesis. Management of patients after diagnosis includes dietary advice and follow-up with supervised OFC at regular intervals to monitor for resolution. Tolerance to the trigger food in children is commonly achieved, a finding not so common in adult-onset FPIES. The aim of this article is to review the most important current concepts in epidemiology, pathophysiology, diagnosis, and management of FPIES.
Improving single nucleotide polymorphisms genotyping accuracy for dihydropyrimidine dehydrogenase testing in pharmacogenetics
Authors: Montella Annalaura , Cantalupo Sueva , D’Alterio Giuseppe , Damiano Vincenzo , Iolascon Achille , Capasso Mario
Published: April 2024

Fluoropyrimidines, crucial in cancer treatment, often cause toxicity concerns even at standard doses. Toxic accumulation of fluoropyrimidine metabolites, culminating in adverse effects, can stem from impaired dihydropyrimidine dehydrogenase (DPYD) enzymatic function. Emerging evidence underscores the role of single nucleotide polymorphisms (SNPs) in DPYD gene, capable of inducing DPYD activity deficiency. Consequently, DPYD genotyping’s importance is on the rise in clinical practice before initiating fluoropyrimidine treatment. Although polymerase chain reaction (PCR) followed by Sanger sequencing (SS; PCR-SS) is a prevalent method for DPYD genotyping, it may encounter limitations. In this context, there is reported a case in which a routine PCR-SS approach for genotyping DPYD SNP rs55886062 failed in a proband of African descent. The Clinical Pharmacogenetics Implementation Consortium (CPIC) categorizes the guanine (G) allele of this SNP as non-functional. The enforcement of whole genome sequencing (WGS) approach led to the identification of two adenine (A) insertions near the PCR primers annealing regions in the proband, responsible for a sequence frameshift and a genotyping error for rs55886062. These SNPs (rs145228578, 1-97981199-T-TA and rs141050810, 1-97981622-G-GA) were extremely rare in non-Finnish Europeans (0.05%) but prevalent in African populations (16%). Although limited evidence was available for these SNPs, they were catalogued as benign variants in public databases. Notably, these two SNPs exhibited a high linkage disequilibrium [LD; squared correlation coefficient (R2) = 0.98]. These findings highlighted the importance to consider the prevalence of genetic variants within diverse ethnic populations when designing primers and probes for SNP genotyping in pharmacogenetic testing. This preventive measure is essential to avoid sequence frameshifts or primer misalignments arising from SNP occurrences in the genome, which can compromise PCR-SS and lead to genotyping failures. Furthermore, this case highlights the significance of exploring alternative genotyping approaches, like WGS, when confronted with challenges associated with conventional techniques.

Published: April 2024

Jet-Fuel desulfurization is one of the most important processes in the petroleum industries due to the high quality required for aviation fuels. In the pre-sent work, the desulfurization of Jet-Fuel with a content of sulfurous compounds was studied using a process assisted with sodium hydroxide. It was considered that the composition of the turbo fuel varies because different blends of crude oil are processed in the refinery under study. The effects of operating conditions, such as reaction time (15 to 30 min) and the amount of caustic soda (NaOH) in its solution (0.024 to 0.2 mol/L) were investigated. The objective functions (responses) were the NaOH consumption and the total cost of production while the acidity and the total sulfur content of Jet-A1 were considered as restrictions. The optimal conditions of the proposed model were obtained using the optimization with the fmincon function of the MATLAB software. These optimal conditions were found to vary according to the content of sulfur compounds present in the process feed. From the optimal points obtained, it was possible to determine the frequency of change of the NaOH solution that allows its maximum use.

Konsumsi air setiap harinya memang merupakan hal yang wajib bagi setiap makhluk hidup. Dalam mengkonsumsi air tentunya selain memperhatikan kandungan vitamin dan mineral yang terkandung di dalamnya juga harus memperhatikan kadar pH pada air tersebut. batas pH air minum menurut PERMENKES No. 416 tahun 1990, yaitu berkisar antara 6.5-8.5. Tujuan dari penelitian ini yaitu untuk mengetahui perbandingan kualitas air minum antara air mineral dan air rebusan yang ditinjau berdasarkan nilai pH pada masing-masing sampel. Metode yang digunakan dalam penelitian ini yaitu obeservasi deskriptif. Penelitian ini menggunakan data secara langsung dengan melakukan pengukuran pH pada setiap sampel yang kemudian membandingkannya dengan teori (deskriptif) pada berbagai sumber yang sesuai. Hasil dari penelitian ini menunjukkan bahwasannya, kedua air baik air rebusan maupun air mineral memiliki pH yang layak untuk dikonsumsi. pH pada air mineral yaitu bernilai 7.4 dan pH pada air rebusan bernilai 6.8. Hasil ini menunjukkan bahwa, kedua air yang diteliti, jika ditinjau dari pH nya maka dapat dikatakan memiliki kualitas yang baik dan layak untuk dikonsumsi. Namun jika ditinjau dari pH air yang lebih mendekati pH netral, maka air rebusan sedikit lebih baik daripada air mineral dari segi kualitas. Hal ini karena pH pada air rebusan lebih mendekati pH netral air yang baik untuk dikonsumsi. Kesimpulan dari penelitian ini yaitu, kualitas air mineral dan air rebusan berdasarkan kadar nilai pHnya memiliki kualitas yang baik karena masih berada di kisaran ketetapan pH air minum yaitu antara 6.5-8.5.

Susceptibility to poor arguments: The interplay of cognitive sophistication and attitudes
Authors: Marin Pinja M. , Lindeman Marjaana , Svedholm-Häkkinen Annika M.
Published: April 2024

Despite everyday argumentation being crucial to human communication and decision-making, the cognitive determinants of argument evaluation are poorly known. This study examined how attitudes and aspects of cognitive sophistication, i.e., thinking styles and scientific literacy, relate to people’s acceptance of poorly justified arguments (e.g., unwarranted appeals to naturalness) on controversial topics (e.g., genetically modified organisms (GMOs)). The participants were more accepting of poorly justified arguments that aligned with their attitudes compared to those that opposed their attitudes, and this was true regardless of one’s thinking styles or level of scientific literacy. Still, most of the examined aspects of cognitive sophistication were also positively related to fallacy detection. The strongest cognitive predictors of correctly recognizing the fallacies were one’s scientific reasoning ability and active open-mindedness. The results thus imply that decreasing misleading attitude effects, and increasing certain aspects of analytic and scientific thinking, could improve argumentation.
