Authors: Chen Yile , Song Junxin
Published: August 2022

Garden of Mountain Russa (Jardim Municipal da Montanha Russa) is a municipal park built in the 19th century in Macau. Because it was located on the edge of the city at the initial stage of construction, near the cemetery, it gradually became abandoned. However, 40 years ago, it was renovated and opened to the public. It belongs to a small-scale hill-type park in a high-density city and has robust research significance for the early native tree species in Macau. The objective of the study is to analyze the environment and plant configuration of small municipal parks in a high-density city and Macau with limited land resources. The results of the study revealed common planting patterns in small municipal parks of mountain type and seasonal analysis of native tree species and plants in Macau. However, due to the problems of diseases and insect pests and improper human handling in the current plant landscape environment, three corresponding solutions were proposed at last.

Besinlerde Oluşan İleri Glikasyon Son Ürünlerine Polifenollerin Etkisi
Authors: Yalçın Ece , Rakıcıoğlu Neslişah
Published: August 2022

İleri glikasyon son ürünleri (AGE) endojen olarak vücutta oluşurken, ekzojen olarak çoğunlukla ısıl işlem görmüş besinlerle vücuda alınmaktadır. Son yıllarda işlenmiş besin tüketiminin artmasıyla diyetle AGE alımı da artmıştır. Besinin bileşimi, nem, pH, hazırlık aşamaları ve pişirme yöntemleri gibi birçok etmen doğrudan veya dolaylı olarak AGE oluşumunu etkilemektedir. Besinlerde AGE miktarı, besinin antioksidan kapasitesi ve asitliği arttırılarak (besinlere limon suyu, sirke vb. eklemek) ve uygun pişirme yöntemleri ile azaltabilmektedir. Polifenoller, proteinlere şeker eklenmesini, glikoksidasyonu ve serbest radikal oluşumunu engelleyerek AGE oluşumunu azaltmaktadır. Günümüzde, yapay AGE inhibitörlerinin olası yan etkilerinden dolayı doğal AGE inhibitörleri olan bitki ekstraktlarının kullanımı artmaktadır. Beslenmede AGE içeren besinlerin tüketiminin azaltılması AGE’lerin vücutta birikimini önlemede etkili bir yaklaşım olabilir. Bu derleme yazı, AGE oluşumu, etki mekanizmasını ve polifenollerin besinlerde AGE oluşumuna etkisini incelemek amacıyla yazılmıştır.

SEJARAH PERKEBUNAN CASSIAVERA DI PULAU SANGKAR KABUPATEN KERINCI 1970-2002
Authors: Yeni Tetti
Published: August 2022

AbstractCassiavera is an export commodity that is used to improve the taste of food, cosmetics and as a healing spice. Cassiavera planted by farmers in Pulau Sangkar, Kerinci Regency, Jambi Province, has been enjoyed internationally and is Indonesia's largest export of this crop and Kerinci itself is one of the cassiavera bases in Indonesia. However, changes in the world economy have an impact on falling cassiavera prices causing reduced income for farmers, so it is necessary to find alternative crops so that people continue to get income in the plantation sector. In 1999 the Kerinci Regency Agriculture and Plantation Service held an agricultural extension program to farmers by forming farmer groups. The Agriculture Service introduces short-term civilization to farmers namely horticultural crops. In the early stages of this transition is not easy for farmers because besides lacking skills in this case also due to the fact that so for the Sangkar Island farmers focus more attention on cassiavera which is considered very easy in its processing.Keywords: Plantation, Cassiavera, AbstrakCassiavera merupakan salah satu komoditi ekspor yang dimanfaatkan untuk meningkatkan cita rasa makan, kosmetik dan sebagai rempah penyembuh. Cassiavera yang ditanam oleh petani Pulau Sangkar Kabupaten Kerinci Provinsi Jambi ternyata telah dinikmati oleh dunia internasional dan merupakan ekspor Indonesia yang terbesar dari tanaman ini dan Kerinci sendiri merupakan salah satu basis cassiavera di Indonesia. Namun perubahan perekonomian dunia berdampak pada penurunan harga cassiavera menyebabkan pendapatan semakin berkurang bagi para petani, sehingga perlu dicari tanaman alternatif agar masyarakat tetap mendapatkan penghasilan yang di sektor perkebunan. Pada tahun 1999 Dinas Pertanian dan Perkebunan Kabupaten Kerinci mengadakan penyuluhan pertanian kepada petani dengan membentuk kelompok tani. Dinas Pertanian ini memperkenalkan pembudayaan jangka pendek kepada petani yakni tanaman holtikultura. Pada tahap awal peralihan ini bukanlah hal yang mudah bagi petani sebab disamping kurang mempunyai skil dalam hal ini juga disebabkan selama ini petani Pulau Sangkar lebih banyak memfokuskan perhatian pada cassiavera yang dianggap sangat mudah dalam pengolahanya.Kata Kunci: Perkebunan, Cassiavera,

Una gran parte de la población mundial vive en las zonas urbanas, y se prevé que el número de personas que vivan en ciudades alcance los 6.000 millones en 2050, lo que supondrá una gran demanda de recursos, haciendo necesaria una transición energética global. Esta transición de las zonas urbanas deberá ser integral e implicará no sólo un cambio de fuentes de energía, sino también un cambio de hábitos que garanticen la sostenibilidad para el desarrollo de las generaciones futuras. En la actualidad, la generación de energía a partir de combustibles fósiles sigue alimentando las ciudades; sin embargo, cada vez es más evidente que las energías renovables son el camino hacia un futuro sostenible, por lo que es necesario promover la autonomía energética en los entornos urbanos. Por otro lado, la generación y eliminación incontrolada de residuos urbanos es un problema que se ha generado debido a la rápida urbanización y al crecimiento de la población; esta falta de planificación de la gestión de residuos hace que las ciudades sean insostenibles. Por ello, se propone la implantación del concepto de economía circular en las zonas urbanas para impulsar la sostenibilidad. Asimismo, se muestra que las ciudades y su entorno regional se enfrentan a nuevos retos sociales y medioambientales que están inextricablemente ligados a la economía. En este sentido, la Universidad Tecnológica Indoamérica organizó el 2do Congreso de Sostenibilidad, Energía y Ciudad para promover la sostenibilidad integral de las ciudades intermedias a corto, medio y largo plazo. Finalmente, invitamos a leer los artículos de esta edición de la revista Cienciamérica donde se hacen algunas reflexiones y debates sobre la gestión sostenible de los recursos en las ciudades intermedias.

Published: August 2022

Background & Objective: Early and accurate diagnosis of thyroid neoplasm is of utmost significance for prolongation of patient survival. A panel of immunomarkers has been tested to overcome the limitation of histopathology. CK-19 is a commonly used immunomarker among them. This study was undertaken to evaluate the diagnostic accuracy of CK-19 in thyroid neoplasm.

Methods & Materials: This cross-sectional study was conducted in the Department of Pathology, Rajshahi Medical College, over a period of two years, from July 2017 to June 2019. A total of 44 tissue blocks of histologically confirmed thyroid neoplasm were included in this study. Then immunohistochemistry was done for CK-19 from a significant paraffin-embedded block.

Result: In the present study, diffuse and strong positivity of CK-19 was found in papillary thyroid carcinoma (PTC), followed by focal positivity in follicular(FC) and medullary carcinoma (MC). A negative staining pattern was found in all cases of follicular adenoma (FA). The sensitivity and specificity of CK-19 were found to be high in the case of PTC, respectively, 88% and 92%.CK-19 expression was highly specific in differentiating malignant from benign thyroid tumors (100%).

Conclusion: The study concluded that CK 19 is a highly sensitive and specific marker in papillary thyroid carcinoma. Diffuse and strong positivity is characteristic of PTC, which can be used in diagnosis with equivocal morphological appearance.

After exclusion total of 72 patients were included in this study, of which 24 had acute inferior MI with RV involvement diagnosed by ≥ 1mm ST-segment elevation in V3R-V5R of right-sided ECG (group-I) and 48 had acute inferior MI without RV involvement (group-II). All patients underwent echocardiography within 24 hours of admission.  The study revealed that RV MPI was significantly increased (0.57± 0.13) in RVMI patients compared to IMI without RVMI (0.24± 0.12). MPI detected RVMI in 08 patients (0.45± 0.09) who did not have ECG findings of RVMI (Group-II). Repeat MPI estimation after 05 days in 21 RVMI (Group-I) and 08 isolated IMI (Group-II) patients who had RVMPI > 0.30showed dramatic reduction of MPI (0.19± 0.07 and 0.22±0.09), respectively. RV MPI ≥ 0.30 has high sensitivity (100%) and specificity (89%) for the diagnosis of RVMI in the presence of acute IMI.  The study recommended that MPI may be a new non-invasive echocardiographic gold standard tool in diagnosing acute RVMI and also assessment of right ventricular function in acute inferior myocardial infarction with high sensitivity and specificity. MPI changes can be serially followed in acute RVMI patients to assess changes in RV function.

Abstract: Sore throat manifested by throat pain is a troublesome issue or discomfort for which physicians are used to prescribing antibiotics, but most often, it is found that the patient is not responding to the drug, which gives rise to the question of drug-resistant or whether there is any infection at all? Nonspecific throat pain also imparts serious public health problems. Self-medication, inadvertent and inadequate doses of antibiotics frequently prescribed by both village doctors and registered MBBS doctors is really a public health problem in developing countries like Bangladesh.

Aims: The aims of this study are to isolate the common organisms in chronic throat infection and to find out the effectiveness of various commonly used antibiotics.

Methods: The samples were collected randomly from sore throat patients via a throat swab in 5 ml of 1% sterilized saline water, and the sample was brought to the laboratory and was inoculated within two hours in both blood agar and nutrient agar (NA) media and samples were incubated at 37°C overnight. Then pure colonies were transferred to Mueller Hinton agar, and antimicrobial susceptibility testing was done by the Kirby Bauer disc diffusion method.

Results: A total of 27(24%) out of 111 samples yield positive growth. In a large number of samples, 84 (76%) did not show any isolation of the pathogenic organism. The predominant organism is a Staphylococcus aureus (55.55%). Thereafter, streptococcus (18.51%), Klebsiellapneumone (14.81%)and Pseudomonas (11.11%).Amoxiclav is the most resistant drug, along with cefuroxime, azithromycin, and doxycycline, respectively. Levofloxacin and ciprofloxacin show intermediate sensitivity. The most sensitive drug used in chronic sore throat found is linezolid though not frequently used, and other sensitive drugs are moxifloxacin and ceftriaxone.

Conclusion: Throat pain or soreness does not always indicate that patient has been infected by bacteria. Rationale and ethical prescription, as well as microbiological sensitivity testing, are considered to avoid drug-resistant strains.

Published: August 2022

Introduction: Community-acquired pneumonia (CAP) is a lower respiratory tract infection occurring in a child who has not resided in a hospital or health care facility in the preceding 14 days. This study was done to determine the risk factors related to the residential environment of CAP among children under five.

Methods: It was a case-control study conducted at the indoor and outdoor units of the Department of Pediatrics and EPI center of Rajshahi Medical College Hospital (RMCH); the study period was two years, from January 2017 to December 2018. The sampling method was purposive sampling. The sample size was 246 children aged 2-59 months, consisting of 123 cases and 123 controls.

Result: A significant association was found between CAP and parental smoking (p =0.000, OR=3.33), overcrowding (p = 0.010, OR =1.96) , indoor air pollution (p = 0.004 ,OR =2.33 ) , exposure to cold & humidity ( p = 0.015 , OR =1.95 ) . The study had identified tobacco smoking of parents, overcrowding, exposure to cold & humidity, indoor air pollution as risk factors for CAP.

Conclusion: CAP is an important cause of morbidity and mortality in under five children (2-59 months) in developing countries like Bangladesh. A huge amount of money is needed to treat the CAP. So, it will be a burden on family and country. However, early detection of the significant risk factors and necessary actions toward these factors help us prevent the development of CAP in under five children (2-59 months) and improve their quality of life.

A espécie Mentha arvensis L., conhecida popularmente como hortelã-japonesa, produz o óleo essencial rico em mentol, cujas aplicações nas indústrias farmacêuticas, alimentícias e cosméticas lhe conferem grande expressão socioeconômica. O objetivo do trabalho foi estudar a secagem e a extração do óleo da hortelã-japonesa. A hortelã-japonesa foi colhida em tempo úmido e quente, com início de floração, acondicionadas de maneira correta e submetidas a secagem em estufa sob duas temperaturas, 40 °C e 60 °C. A umidade das amostras encontradas foi de 86,73 %. Em seguida foram obtidas as curvas de secagem nas duas temperaturas e determinado que o modelo de secagem que melhor se ajustou ao experimento foi o modelo de Peleg. Após a secagem, fez-se a moagem em moinho de facas das duas frações separadamente, posteriormente determinou-se o diâmetro de Sauter a 40 °C: 0,237 mm e 60 °C: 0,250 mm. Após a determinação do diâmetro de Sauter, a extração exaustiva do óleo foi realizada em aparelho de Soxhlet utilizando n-hexano como solvente extrator com as amostras retidas nas peneiras de malhas 70 e 100 de diâmetros 0,150 e 0,215 mm para as amostras secas em temperaturas de 40 °C e 60 °C, pois foram as peneiras que obtiveram a maior massa redita da hortelã-japonesa desidratada. O rendimento da extração do óleo da fração seca a 60 °C apresentou melhor rendimento nos diâmetros estudados, obtendo 3,74 % de rendimento de extração do óleo essencial. Observando o rendimento da extração em relação ao diâmetro das amostras, o diâmetro de 0,180 mm foi melhor nas diferentes temperaturas. Onde se pode concluir que a temperatura e diâmetro das partículas da hortelã-japonesa influenciam no rendimento da extração do óleo essencial.

Published: August 2022

Energy consumption in the chemical and petrochemical industries is dominated by the highly energy-intensive, high-temperature hydrocarbon cracking process. This paper offers an attractive solution to potentially decarbonise the cracking industry by direct renewable electrification whilst also improving the efficiency of energy transfer and enhancing the quality of the overall cracking process. Controlled endothermic cracking reactions are generated by direct mechanical energy transfer using a new electric-motor-driven turbo-reactor to replace the fossil-fuelled radiant unit in the conventional cracking plant. This study provides an introduction to the novel concept, focusing on how the unique three-blade-row repeating stage design is exploited in order to drive the efficient energy transfer and transformation processes used to overcome the fundamental limitations of the conventional process. More specifically, this includes increasing the primary product yield, mitigating coke deposition and improving operability. A combination of URANS and high-fidelity LES are presented in order to probe the aerothermal flow physics and interactions in the rotor and diffuser. This study clearly demonstrates how the working principals of the elemental stage can be realised uniformly across the full regenerative turbo-reactor by exploiting the robust and naturally self-adjusting concept. This work highlights the high-level of controllability of the turbomachine, which allows the cracking environment and species selectivities to be tailored during operation, for example, by conducting minor alterations to the rotational speed.
