Published: September 2023

The rapid economic and population growth of Pontianak City has triggered an increase in domestic waste. The composition of Pontianak City waste in 2020 is dominated by organic waste (91.8%). The wood processing industry will produce 50% of its waste, as sawdust. One of the efforts to reduce the generation of organic waste and sawdust is to use it as fuel in the form of environmentally friendly bio-briquettes. This paper studies the chemical characteristics of calorific value, moisture content, and ash content as they variations in the composition of the resulting bio-briquettes. The research methods include drying, curing, sieving at 40 mesh, mixing charcoal with 15% starch adhesive, and compaction. The composition variations in this study were sawdust (SG): organic waste (SO) (85%:15%, 75%:25%, and 65%:35%). The results showed that the highest calorific value was found in the composition variation of sawdust (SG) at 85%:15% organic waste (SO) of 49 cal/gr, while the highest water content was 20.52% and the highest ash content was 14.57% in the variation of the composition of sawdust (SG) 65%:35% organic waste (SO). The results of the chemical characteristics of calorific value, moisture content, and ash content of bio-briquettes did not meet the requirements of SNI 01-6235-2000.Â Keywords: bio-briquettes, alternative energy, organic waste, sawdustÂ Â ABSTRAKÂ Pesatnya pertumbuhan ekonomi dan penduduk Kota Pontianak memicu peningkatan sampah domestik.

Objectives:
Endoscopic endonasal approach (EEA) is commonly used for resection of craniopharyngioma (CP). Treatment outcomes of EEA for CP were related to numerous factors; however, they have been evaluated in few studies. The objective of this study is to investigate factors associated with the outcomes of CP following this operation.

Materials and Methods:
The records of patients with CP, who underwent EEA at our institution from January 2014 to June 2022, were retrospectively reviewed. Surgical outcomes, including the extent of resection, visual recovery, and endocrinological outcomes, were reported. Clinical and radiographic factors were analyzed for their associations with treatment outcomes using logistic regression analyzes.

Results:
This study cohort consisted of 28 patients with CP. Gross total resection (GTR) was achieved in 12 patients (43%). Post-operative visual status improved, stabilized, and deteriorated in 89%, 6%, and 6% of the patients, respectively. There were no patients recovered from pre-operative pituitary dysfunctions, while post-operative hypoadrenalism, hypothyroidism, and hypogonadism were found in 9 (36%), 11 (42%), and 4 (22%) patients, respectively. Post-operative permanent diabetic insipidus was found in 13 patients (50%). Greater suprasellar extension of the tumor was associated with a lower rate of GTR (P = 0.011). Diabetes mellitus (DM) was associated with poor visual recovery (P = 0.022). Larger tumor size and Puget grade 2 were associated with postoperative hypoadrenalism (P = 0.01 and 0.023, respectively). In addition, Puget grade 2 was associated with post-operative hypothyroidism (P = 0.017).

Conclusion:
For EEA in CP, the extent of resection could be determined by suprasellar extension of the tumor. DM was a poor predicting factor for visual recovery, while larger tumors and Puget grade 2 had a higher risk of post-operative hypopituitarism.

Повреждаемость ДНК лимфоцитов периферической крови и клеток головного мозга крыс оценивали щелочной версией метода «ДНКкомет» сразу после действия электромагнитного излучения и тестирующего УФ - излучения. Установлено, что низкоинтенсивное электромагнитное излучение увеличивало повреждаемость ДНК клеток крови и головного мозга по сравнению с контролем (р≤0,05). Cодержание ДНК в «хвосте кометы» в клетках головного мозга оказалось в 2 раза ниже, чем в клетках крови. Дополнительная тестирующая УФ-нагрузка усиливала биоэффекты действия ЭМИ.
We assessed the damage to DNA in peripheral blood lymphocytes and rat brain cells by the alkaline version of the "DNA comet" method immediately after exposure to electromagnetic radiation and testing UV radiation. We found that low-intensity electromagnetic radiation increased the level of the damage to DNA in blood and brain cells compared to the control (p≤0.05). The content of DNA in the “comet tail” in brain cells turned out to be 2 times lower than in blood cells. An additional UV-load enhanced the bioeffects of the EMR action.

Published: September 2023

Плацента человека – временный орган, выполняющий множество физиологических функций, в числе которых снабжение плода питательными веществами и удаление продуктов его жизнедеятельности, обеспечение газообмена между матерью и плодом, синтез различных гормонов. Эти функции определяются строением плацентарного барьера. До настоящего времени имеющаяся морфологическая информация о плаценте, накапливалась на основе исследований на уровне световой микроскопии. Однако, поскольку плацента является структурно сложным органом, состоящим из многих типов клеток различного происхождения, в последнее время появляется повышенный интерес и необходимость получения подробной информации об ультраструктуре каждой области плаценты, чтобы точно классифицировать патологию беременности и родов. С помощью электронной микроскопии были выявлены ультраструктурные особенности плацент, полученных на сроке беременности 39-40 недель. Обнаружено, что к концу беременности плацентарный барьер становится значительно тоньше, за счет утраты слоя цитотрофобласта под синцититрофобластом, за счет чего резко увеличивается площадь обменной поверхности.
The human placenta is a temporary organ that performs many physiological functions, including the supply of nutrients to the fetus and the removal of its waste products, ensuring gas exchange between the mother and the fetus, the synthesis of various hormones. These functions are determined by the structure of the placental barrier. To date, the available morphological information about the placenta has been accumulated during studies uner the light microscope. As a structurally complex organ consisting of many types of cells of various origins the placenta, each region. Tthis is necessary, among others, to classify accurately the pathology of pregnancy and childbirth. Here we revealed the ultrastructural features of placentas obtained at 39-40 weeks gestation using electron microscopy. We found that the placental barrier becomes much thinner by the end of pregnancy. This happens due to the loss of the cytotrophoblast layer under the syncytitrophoblast, which dramatically increases the exchange surface area.
Impact of PHDs Trained in Europe and North America on the Productivity of Scientific Research: Evidence from Latin America
Authors: Morales Nicolás Andres Núñez , Paredes Sandro Alberto Sanchez 
Published: September 2023

Purpose: The main purpose of this study is to analyze the differences in research productivity between doctoral degree holders from European and North American universities, and doctoral degree holders from Peru.

Theoretical framework: Internationalization of higher education has become a phenomenon of great relevance in recent years (Romani et al., 2021), allowing an increasing number of doctoral researchers to study in foreign countries. However, little evidence has been generated in Latin America.

Design/Methodology/Approach: The study uses an explanatory approach based on data mining that analyze data from 863 researchers from 24 public and private universities in Perú, according to the two categories of productivity (high and low) defined by the National Scientific Research Agency.

Findings: The results show that of all the factors analyzed, the country of doctoral study is the most important variable in predicting the scientific productivity of researchers. This situation is confirmed when analyzing the number of publications made by researchers according to their category, where a clear tendency in favor of researchers who studied abroad can be seen.

Research, Practical & Social implications: The results suggest that international academics are more likely to publish in top-tier journals. Also, the results may be applicable to other countries, but more studies are going to be necessary.

Originality/Value: The results of this investigation are relevant, because studies about the academic internationalization effects on scientific productivity are scarce and no previous studies about this topic have been conducted in Latin America.
