Published: November 2023

Aphis craccivora (Hemiptera: Aphididae) is an important pest affecting various crops worldwide. However, only few studies have been conducted on the infection of A. craccivora by Lecanicillium and related insecticidal mechanisms. We investigated the infection process of A. craccivora by Lecanicillium araneicola HK-1 using fluorescence microscopy and scanning electron microscopy (SEM), and our results indicated that the conidia of strain HK-1 easily attached to the feet and dorsum of A. craccivora. The activities of chitinase and extracellular protease were induced in the aphid after treatment with HK-1. A bioassay on A. craccivora showed that the median lethal concentration (LC50) of the fungus crude extract was 24.00 mg mL−1 for 24 h of treatment. Additionally, the results showed that the crude extract disrupted the enzyme system of A. craccivora, inducing the inhibition of carboxylesterase (CarE) and the induction of glutathione S-transferase (GST) and acetylcholinesterase (AChE). Combining these results with those of a gas chromatography–mass spectrometry (GC-MS) analysis, it is suggested that p-cymene, hymecromone, 9,12-octadecadienoic acid (Z, Z) methyl ester, and 9,12-octadecadienoic acid (Z, Z) may be connected to the insecticidal effects we observed. This study provides a theoretical basis for the use of L. araneicola HK-1 as a potential biological control agent.

The aim of this study was to characterise the microstructural organisation of staple carbon fibre-reinforced polymer composites and to investigate their mechanical properties. Conventionally, fibre-reinforced materials are manufactured using continuous fibres. However, discontinuous fibres are crucial for developing sustainable structural second-life applications. Specifically, aligning staple fibres into yarn or tape-like structures enables similar usage to continuous fibre-based products. Understanding the effects of fibre orientation, fibre length, and compaction on mechanical performance can facilitate the fibres’ use as standard engineering materials. This study employed methods ranging from microscale to macroscale, such as image analysis, X-ray computed tomography, and mechanical testing, to quantify the microstructural organisations resulting from different alignment processing methods. These results were compared with the results of mechanical tests to validate and comprehend the relationship between fibre alignment and strength. The results show a significant influence of alignment on fibre orientation distribution, fibre volume fraction, tortuosity, and mechanical properties. Furthermore, different characteristics of the staple fibre tapes were identified and attributed to kinematic effects during movement of the sliver alignment unit, resulting in varying tape thicknesses and fuzzy surfaces.

Authors: Ding Yanru , Zhao Weichen , Zhu Guikai , Wang Quanlong , Zhang Peng , Rui Yukui
Published: November 2023

It is estimated that 40–70%, 80–90% and 50–90% of the conventional macronutrients N, P and K applied to the soil are lost, respectively, resulting in considerable loss of resources. Compared to conventional fertilizers, nanofertilizers have the advantages of controlled release, high nutrient utilization, low cost and relatively low environmental pollution due to their small size (1–100 nm) and high specific surface area. The application of nanofertilizers is an up-and-coming field of agricultural research and is an attractive and economical substitute for common fertilizers which can boost global food productivity sustainably. Foliar fertilization is a popular way to satisfy the needs of higher plants. Because of its small application dose, faster nutrient uptake than soil application and relatively less environmental pollution, foliar fertilization is more popular among plants. It can be seen that nanofertilizers and foliar fertilization are the hotspots of attention at present and that current research on the foliar application of nanofertilizers is not as extensive as that on soil application. Based on this background, this paper provides an overview of various applications of foliar spraying of nanofertilizers in agriculture, including applications in improving crop yield and quality as well as mitigating heavy metal stress, salt stress and drought stress.

Published: November 2023

The process of arranging magnetic nanoparticles (MNPs) into long-range structures that can be dynamically and reversibly controlled is challenging, although interesting for emerging spintronic applications. Here, we report composites of MNPs in excess of LC-like ligands as promising materials for MNP-based technologies. The organic part ensures the assembly of MNP into long-range ordered phases as well as precise and temperature-reversible control over the arrangement. The dynamic changes are fully reversible, which we confirm using X-ray diffraction (XRD). This methodology allows for the precise control of the nanomaterial’s structure in a thin film at different temperatures, translating to variable unit cell parameters. The composition of the materials (XPS, TGA), their structure (XRD), and magnetic properties (SQUID) were performed. Overall, this study confirms that LC-like materials provide the ability to dynamically control the magnetic nanoparticles in thin films, particularly the reversible control of their self-organization.
Stakeholders’ Perceptions of How Nurse–Doctor Communication Impacts Patient Care: A Concept Mapping Study
Authors: Pantha Sandesh , Jones Martin , Gray Richard
Published: November 2023

There is some evidence that aspects of nurse–doctor communication are associated with the quality of care and treatment patients receive whilst they are in hospital. To date, no studies have examined stakeholder perceptions on how patient care is influenced by clinical communication between nurses and doctors. We conducted a concept mapping study to generate a deep understanding of how clinical communication impacts patient care. Concept mapping has six phases: preparation, idea generation, structuring, representation, interpretation, and utilization. A total of 20 patients, 21 nurses, and 21 doctors participated in the study. Brainstorming generated 69 discreet statements about how nurse–doctor communication impacts patient care. The structuring (rating and clustering) phase was completed by 48 participants. The data interpretation workshop selected a five-cluster solution: effective communication, trust, patient safety, impediments to patient care, and interpersonal skills. On the final concept map, the five clusters were arranged in a circle around the center of the map. Clusters were relatively equal in size, suggesting that each concept makes a broadly equal contribution to how nurse–doctor communication influences patient care. Our study suggests that there are multiple aspects of clinical communication that impact patient care. Candidate interventions to enhance nurse–doctor communication may need to consider the complex nature of interprofessional working. Registration: This study was prospectively registered with the Open Science Framework (OSF) on 09.07.2020 (osf.io/9np8v/) prior to recruiting the first participant.

Diverse Bradyrhizobium spp. with Similar Symbiosis Genes Nodulate Peanut in Different Regions of China: Characterization of Symbiovar sv. Arachis
Authors: Zhang Junjie , Feng Yufeng , Wang Jingqi , Wang Entao , Andrews Mitchell
Published: November 2023

A total of 219 rhizobial strains isolated from peanut grown in soils from six peanut croplands in Zhengyang county, Henan Province, were typed by PCR-RFLP of IGS sequences. Their phylogenetic relationships were refined on representative strains using sequence analyses of 16S rRNA genes, housekeeping genes (atpD, recA, glnII) and symbiosis genes (nodA, nodC and nifH). The 219 rhizobial isolates were classified into 13 IGS types, and twenty representatives were defined within eight Bradyrhizobium genospecies: B. guangdongense covering 5 IGS types (75.2% of total isolates), B. guangzhouense (2 IGS types, 2.7% total isolates), B. zhengyangense (1 IGS type, 11.3% total isolates) and five novel genospecies (5 IGS types, 0.9 to 3.2% total isolates). All representative strains had identical nodA, nodC and nifH sequences except for one nifH sequence. With this one exception, these sequences were identical to those of the type strains of Bradyrhizobium species and several Bradyrhizobium genospecies isolated from peanut in different regions of China. The nodC sequences of all strains showed < 67% similarity to the closest strains on the Genbank database indicating that they are representative of a novel Bradyrhiobium symbiovar. This study has shown that (1) diverse Bradyrhizobium spp. with similar symbiosis genes nodulate peanut in different regions of China. (2) Horizontal transfer of genes involved in nodulating peanut is common between Bradyrhizobium species in soils used to grow the crop in China. (3) The strains studied here are representative of a novel Bradyrhizobium symbiovar that nodulates peanut in China. We propose the name sv. arachis for this novel symbiovar indicating that the strains were isolated from Arachis hypogaea. Results here have practical implications in relation to the selection of rhizobial inoculants for peanut in China.

Authors: Bacińska Zuzanna , Baberowska Kinga , Surowiak Alicja Karolina , Balcerzak Lucyna , Strub Daniel Jan
Published: November 2023

Currently, one of the most serious global problems is the increasing incidence of infectious diseases. This is closely related to the increase in antibiotic use, which has resulted in the development of multidrug resistance in microorganisms. Another problem is the numerous microbiological contaminations of cosmetic products, which can lead to dangerous bacterial infections in humans. Natural fragrance raw materials exhibit a wide spectrum of biological properties, including antimicrobial properties. Despite their prevalence and availability on the commercial market, there is little research into their effects on multidrug-resistant microorganisms. This study examines the inhibitory effect of natural substances on Gram-positive and Gram-negative bacteria. For this purpose, screening and appropriate assays were carried out to determine the minimum inhibitory concentration (MIC) value of individual substances, using the alamarBlueTM reagent. The lowest MIC values were observed for Staphylococcus aureus (black seed (Nigella sativa) expressed oil, MIC = 25 µg/mL), Kocuria rhizophila (fir balsam absolute, MIC = 12.5 µg/mL), and Pseudomonas putida (cubeb oil and fir balsam absolute, MIC = 12.5 µg/mL). The most resistant Gram-negative species was Enterobacter gergoviae, while Staphylococcus epidermidis was the most resistant Gram-positive species.
High-Speed Railway Network, City Heterogeneity, and City Innovation
Authors: Zhao Kunlun , Li Wenxing
Published: November 2023

The emergence of the time–space contraction effect from the high-speed railway (HSR) network in China has been beneficial in breaking down regional divisions, thus facilitating the circulation of resources and optimizing resource distribution and production efficiency. However, research has not adequately addressed the city disparities of the HSR network and their effects on city innovation. Through the heterogeneity perspective of ‘New’ new economic geography, this study employs the 2008–2019 panel data at the city level in China and builds a spatial Durbin model based on continuous spatial difference in differences to investigate the mechanism of the HSR network on city innovation and to analyze its agglomeration and diffusion effect of innovative factors under different city sizes and spatial perspectives. This study revealed that the HSR network could significantly increase the innovation of local cities and neighboring cities, yet there is a certain threshold of city size that affects city innovation. Large cities covered by HSRs can take advantage of gathering talent, financial capital, and industry from nearby regions, thus constructing a new spatial pattern of innovative development. This study also found that the innovation accelerative effect gradually decreases as the distance from the city covered by HSRs increases and completely disappears at the distance of 400 km. Therefore, it is necessary to optimize the HSR network and increase the mobility and agglomeration of innovative elements between cities, thus deepening the collaboration between cities through differentiated strategies. This will enhance the spatial spillover effect of innovation, thus ultimately achieving a balanced spatial pattern of city innovation.
Are There Sex Differences in the Prevalence and Severity of Early-Stage Trauma-Related Stress in Mildly Impaired Autistic Children and Adolescents?
Authors: Bitsika Vicki , Sharpley Christopher Francis
Published: November 2023

There is some evidence that autistic children experience more traumatic events than non-autistic children, but little research attention has been given to sex differences on this issue. This study investigated the presence of sex-based differences in the occurrence and severity of trauma-related events and resultant stress in autistic youth, and tested the null hypothesis of no sex differences. A sample of 32 autistic males and 32 autistic females (6 yr to 18 yr), plus one of their parents, participated in a survey study of (a) the presence of a traumatic event and ongoing stress regarding that event, and (b) recurrent memories or dreams of that event. Although the autistic children rated their experience of trauma, plus their recurrent memories or dreams of that event, as more severe than their parents did, neither of these sources of information showed any significant sex differences in the total score or diagnostic frequency for trauma-related stress. There were no significant correlations between age, IQ, or autism severity and trauma-related stress scores for the autistic males or females. These results challenge the generalizability of the prevalence of sex differences in trauma-related stress that has been reported in the wider community, arguing that equal attention should be given to male and female autistic youth for this possible comorbidity.
Reivindicación de la Ciencia aplicada a la Educación
Authors: Ceballos Vélez Adolfo , Maury Mena Sara Concepción , Navarro Angarita Vanessa , García Caro Abril Isabel
Published: November 2023

El ensayo recoge las reflexiones sobre el desarrollo histórico y social de dos actividades inherentes al ser humano: la Ciencia y la Educación. La Ciencia, que surge como un nuevo tipo de visión sobre la realidad perceptible, que trasciende otro tipo de explicaciones posibles, entre ellas, las mitológicas o las subjetivas derivadas del sentido común, mediante un proceso que se fue perfeccionando con el paso de los siglos. Y la Educación, vista en sus comienzos como actividad mecánica, instruccional o de adoctrinamiento (relegada al terreno abstracto de la Filosofía), que resurge a mediados del siglo XX tras la debacle de la segunda guerra mundial, como proceso transformador de un hombre nuevo para un mundo nuevo. Por lo cual, el ensayo también analiza la reivindicación de las «Ciencias Sociales y Humanas» como herramienta que posibilitó la construcción de consensos transformadores durante el periodo de posguerra para lograr la recuperación del sentido humano, que es común a los pueblos y naciones como un todo social. Finalmente, el documento aborda la necesidad de investigar en Educación con el fin de entender y mejorar los procesos de enseñanza y aprendizaje, siendoun terreno en el que confluyen otras ciencias afines como la Psicología y la Neurología. Las conclusiones refuerzan el análisis, mostrando la manera armoniosa en que se integran conocimiento y humanismo a través de los procesos de Ciencia y Educación, como reflejo de de la condición humana.
El pasado filosófico local
Authors: López Jiménez Carlos Arturo
Published: November 2023

Enseñar historia de la filosofía en los programas de filosofía universitarios es mucho más que transmitir información sobre el pasado de una disciplina académica. En este artículo se indica la triple función de la tradición de referencia en la formación de agentes de la filosofía: histórica, didáctica y metodológica. Ello con el fin de incitar la producción de reflexiones sobre el lugar del pasado filosófico local y sus posibles concreciones como historias de la filosofía en Colombia, o su participación en las historias sobre la tradición de referencia, incluso como insumos para cursos que no sean históricos, sino problemáticos. Así, a lo largo de este documento se encuentran indicaciones sobre cómo enriquecer no solo las historias de la filosofía sino otros posibles cursos dentro de los programas de formación filosófica profesional.
Una filosofía de la universidad a partir de Jacques Derrida
Authors: Sierra Blanco Luis Fernando
Published: November 2023

¿En qué consistiría una filosofía de la universidad? ¿Cómo esbozar el modo en que ésta puede proceder? ¿Qué puede decir hoy la filosofía para quienes trabajan en esta institución? Para responder estas preguntas se propone revisar algunos de los textos en los que el pensador de origen argelino habla de manera directa sobre la universidad: Las pupilas de la Universidad, La Universidad sin condición y Cátedra vacante: censura, maestría y magistralidad. Los tres textos fueron escritos para ser leídos en público como lecciones inaugurales o conferencias. La tesis de este artículo es que una filosofía de la universidad debe asumir que esta institución es el lugar en el que todo debe ser cuestionado y debe reflexionar críticamente sobre las metáforas que se usan para referirse a su razón de ser, su esencia y fundamento. Para desarrollar la idea central el artículo se organiza en cuatro partes: primero, se revisa el modo de proceder y las preocupaciones generales, a partir de la relación que se puede establecer con elementos de dos textos de Martin Heidegger; segundo, se examina las metáforas sobre la visión y la luz; tercero, se reflexionará sobre la destinación y razón de ser de la universidad; por último, se tratará la pregunta ¿quiénes somos nosotros en esta corporación de profesores y alumnos?

En los años recorridos de este siglo XXI la filosofía de la educación y la enseñanza de la filosofía, particularmente en Colombia e Iberoamérica, se han convertido en campos de acción y de profunda reflexión. Dado que ponen en discusión la relación de las filosofías con su pasado, con las instituciones y llevan necesariamente a preguntarnos por su quehacer en el presente y sus condiciones a futuro. Los debates teóricos y la confrontación de perspectivas han venido ganando fuerza, como lo evidencia la producción académica derivada de resultados de investigación, y las reflexiones realizadas por docentes de filosofía en facultades o programas de filosofía al igual que en los espacios universitarios de formación en educación. Un buen número de publicaciones de artículos de revistas y libros, así como contenidos en formatos de radio, blogs y otros posibilitados por plataformas de internet y redes sociales, dan cuenta de esta fructífera y necesaria producción intelectual en un área que es igualmente importante y necesaria para la formación y quehacer filosófico en Colombia e Iberoamérica. Además, es destacable la periódica realización de congresos internacionales, nacionales y las asociaciones que tienen a la enseñanza de la filosofía y a su relación con el discurso y la práxis educativa como nodos importantes.

The Indonesian Stock Exchange Index (BEI) is the main indicator of the Indonesian stock market. The problem in this research is a specific issue to solve the practical problem of predicting the future movement of the BEI index which has strategic value for investors, traders and companies in Indonesia. The aim of this research is to be able to predict the BEI index until the end of 2023, because the stock exchange plays a big role for the Indonesian economy as an economic and financial function. Traditional approaches such as ARIMA (Autoregressive Integrated Moving Average) have been used to predict the movement of the BEI index. However, in recent years, machine learning and data mining techniques have become popular as more sophisticated alternative approaches. This research uses a combined approach between ARIMA and machine learning with R Programming. Daily IDX index data from January 2012 to December 2022 will be taken from Yahoo Finance. This data will then be cleaned and processed using R Programming. The ARIMA approach will be used as a baseline to compare machine learning performance. The results focus on the estimated closing stock prices for the next 365 days or the average until the end of 2023. The Time Series value of the possible minimum/maximum predicted value for IDX shares in 2023 is a minimum predicted value of 6786,212 - 6849,559, a maximum predicted value of 6850,093 - 7086,012. Trends represent a good approach in predicting the future direction of closing prices.

ABSTRACT

This research is motivated by the causes of IMR (Infant Mortality Rate). The biggest direct causes of infant mortality during 2018 are LBW 14%, pneumonia 13.2%, diarrhea 17.2%, hyperbilirubin 3%, nutritional deficit 3%, sepsis 22%, congenital abnormalities 4.9%, tetanus 1.5% , Sepsis, respiratory distress syndrome 14% and unknown cause 5.5%. One of the factors that play a role in this high IMR is the period of baby growth and development of 0-6 months requires nutritional intake obtained through exclusive breastfeeding. Factors that can reduce IMR themselves are nutrient factors found in breast milk guarantee good nutritional status and reduce morbidity and mortality of children.Exclusive breastfeeding is only breastfeeding for infants up to 6 months of age without the addition of fluids or other foods. Growth disorders at the beginning of a baby's life are caused by the mother not giving exclusive breastfeeding to her baby. This is of course closely related to the low coverage of exclusive breastfeeding. For this reason, pregnant women need knowledge about exclusive breastfeeding, so this research aims to find out the description of the knowledge of pregnant women about Exclusive ASI. The method used is a systematic literature review. Secondary data collection techniques with 3 research journals. Literature review results from the three research journals show that based on the knowledge of respondents in the results of journal 1 research that is the level of sufficient knowledge as much (65%), the results of the 2nd journal are quite knowledgeable as much as (60.4%) and the results of the third journal good knowledgeable average (76.2%). It can be concluded that the description of pregnant women about Exclusive ASI is categorized as having sufficient knowledge, this is influenced by education and information. Recommendations to health care institutions to streamline promotive action. One way to do this is to provide counseling on exclusive breastfeeding to pregnant women in the Puskesmas target area. Thus pregnant women understand about the importance of exclusive breastfeeding for babies.

Buah Binahong memiliki kandungan antosianin yang memberikan warna merah keunguan sehingga dapat digunakan sebagai alternative pengganti Eosin 2%. Tujuan penelitian ini adalah untuk mengetahui ada tidaknya perbedaan kulitas preparat telur cacing yang diwarnai dengan sari buah Binahong dengan Eosin 2%. Metode pemeriksaan telur cacing yang digunakan yaitu metode langsung yang kemudian diwarnai dengan sari buah Binahong langsung, 75%, 50% dan 25% dengan variasi pH 2 dan pH 12. Hasil uji Kruskal wallis sari buah Binahong 100% pH 2 memberikan hasil yang hamper mendekati Eosin 2% dan hasil uji Mann U whitney Nilai Asym. Sig. (2-tailed) sari buah Binahong 100% pH 2 > 0,05. Dari hasil penelitian ini didapatkan bahwa sari buah Binahong 100% pH 2 dapat dimanfaatkan sebagai pewarna pada pemeriksaan telur cacing STH pengganti Eosin 2%.

Mycobacterium tuberculosis masuk ke dalam tubuh sehingga menyebabkan inflamasi. Sel makrofag merangsang inflamasi dengan melepaskan sitokin seperti IL-6, di mana IL-6 memicu hati untuk menghasilkan protein fase akut yang disebut CRP dan fibrinogen, yang bertindak sebagai protein ekstraseluler, merangsang fagosit untuk memfagosit bakteri. Monosit memainkan peran penting dalam respon imun terhadap infeksi tuberkulosis. Jenis penelitian yang digunakan adalah deskriptif kuantitatif dengan pendekatan korelatif. Jenis sampling adalah kuota sampling, dimana teknik harus mengalokasikan sampel dari populasi dengan karakteristik tertentu ke kuantitas (kuota) yang diinginkan. Terdapat 16 sampel (53%) yang memiliki persentase monosit dan CRP dalam kisaran normal, 3 sampel (10%) memiliki monosit dalam kisaran normal tetapi CRP meningkat, 5 sampel (17%) memiliki monosit meningkat, tetapi nilai CRP  dalam kisaran normal dan 6 sampel (20%) menunjukkan peningkatan jumlah monosit dan kadar CRP. Pada penderita tuberkulosis paru, setelah tiga bulan pengobatan, terdapat hubungan antara proporsi monosit dengan kadar CRP. Secara statistik uji korelasi Spearman menunjukkan adanya hubungan yang signifikan dengan nilai signifikansi 0,010 dan nilai koefisien korelasi sebesar 0,463 artinya hubungan kedua variabel searah dengan kategori hubungan cukup.

Pemeriksaan kadar kolesterol total serum merupakan bagian dari pemeriksaan profil lipid yang harus memperhatikan waktu inkubasi agar hasil pemeriksaan yang didapatkan merupakan hasil yang akurat dan valid. Namun, dalam beberapa kasus waktu inkubasi tidak terlalu diperhatikan disebabkan banyaknya permintaan pemeriksaan. Tujuan penelitian yaitu untuk mengetahui pengaruh waktu inkubasi 10, 30, 60, 90, 120, dan 150 menit  terhadap kadar kolesterol total serum. Penelitian ini merupakan eksperimen laboratorium dengan jumlah sampel 4 orang Mahasiswa Jurusan Teknologi Laboratorium Medis Poltekkes Kemenkes Bandung. Desain penelitian yang digunakan yaitu quasy experimental dengan memberikan perbedaan perlakuan lama waktu inkubasi pada pemeriksaan kadar kolesterol total serum. Analisis data yang digunakan yaitu Uji General Linear Model (GLM) dan Uji F.  Hasil rata-rata kadar kolesterol total serum mengalami penurunan seiring bertambahnya waktu inkubasi. Uji GLM menunjukkan nilai Sig. waktu inkubasi 30 menit dan 60 menit yaitu 0,561 dan 0,091 dimana nilai Sig. > 0,05 yang artinya kadar kolesterol total serum waktu inkubasi 30 dan 60 menit secara statistik tidak terdapat perbedaan yang signifikan dengan kadar kolesterol total serum waktu inkubasi 10 menit. Nilai Sig. waktu inkubasi 90, 120, dan 150 yaitu 0,000 dimana nilai Sig. < 0,05 yang artinya kadar kolesterol total serum waktu inkubasi 90, 120 dan 150 menit secara statistik terdapat perbedaan yang signifikan dengan kadar kolesterol total serum waktu inkubasi 10 menit. Uji F menunjukkan nilai Sig. 0,000 dimana nilai Sig. < 0,05 yang artinya waktu inkubasi memiliki pengaruh terhadap kadar kolesterol total serum. Terdapat pengaruh penurunan kadar kolesterol total serum seiring bertambahnya waktu inkubasi.

Salah satu tahapan pemeriksaan laboratorium adalah tahapan pra analitik, dimana tahapan tersebut memiliki persentase kesalahan yang paling besar, yaitu sebesar 68%. Pemeriksaan aktivitas enzim alkali fosfatase merupakan salah satu pemeriksaan untuk mengetahui adanya kelainan, penyakit, dan kerusakan pada jaringan hati. Penelitian ini bertujuan untuk mengetahui stabilitas aktivitas enzim ALP pada serum dan plasma heparin pada suhu ruang. Penelitian ini merupakan quasy eksperimental dengan memberi perlakuan berupa penyimpanan sampel serum dan plasma heparin selama 10, 12, dan 14 jam pada suhu ruang yang kemudian aktivitas enzim dibandingkan dengan aktivitas pada sampel segera diperiksa, Didapatkan 64 data pemeriksaan yang diolah menggunakan SPSS dengan uji general liear model (GLM). Penelitian ini mendapatkan hasil uji GLM sampel serum dengan variasi lama simpan 10, 12, dan 14 jam menunjukkan nilai sig. 0,220, 0,262, dan 0,062. Sedangkan pada sampel plasma heparin menunjukkan nilai sig. 0,118, 0,271, dan 0,053 (Sig.>0,05). Sehingga dapat dihasilkan bahwa tidak terdapat perbedaan yang signifikan antara variasi lama simpan dengan pemeriksaan segera. Hasil uji GLM antara sampel serum dan plasma heparin pada pemeriksaan segera, setelah 10, 12, dan 14 jam menunjukkan nilai sig. 0,054, 0,080, 0,050, dan 0,136 (Sig.> 0,05). Maka, tidak terdapat perbedaan yang signifikan pada setiap variasi lama simpan. Maka, dari penelitian ini disimpulkan bahwa tidak terdapat perbedaan antara stabilitas aktivitas enzim pada serum dan plasma heparin, yaitu tetap stabil hingga 14 jam pada suhu ruang.

Deparafinisasi bertujuan untuk melarutkan kelebihan parafin dari jaringan, umumnya menggunakan xylol. Mempertimbangkan kelemahan xylol seperti berbahaya jika kontak dengan kulit, maka lebih baik jika mengganti xylol dengan bahan alternatif seperti virgin coconut oil (VCO). Penggunaan VCO sebagai bahan alternatif xylol harus diikuti dengan pemanasan dengan suhu yang bervariasi. Tujuan penelitian ini untuk melihat ada tidaknya pengaruh variasi suhu dan waktu VCO pada proses deparafinisasi terhadap kualitas preparat dan perbedaan kualitas preparat menggunakan VCO dengan xylol sebagai bahan deparafinisasi jaringan. Penelitian ini menggunakan metode quasi eksperimen dengan menggunakan jaringan hepar Rattus novergicus yang diberikan 5 perlakuan pada proses deparafinisasi yaitu menggunakan larutan xylol pada suhu kamar selama 5 menit, dan VCO pada suhu 50°C dan suhu 60°C dengan masing-masing suhu direndam selama 10 menit dan 15 menit. Hasil penelitian menunjukkan bahwa preparat yang menggunakan VCO pada suhu 50°C memberikan hasil kualitas preparat yang lebih baik dibandingkan dengan VCO pada suhu 60°C. Pada suhu 50°C secara mikroskopis didapatkan preparat dengan warna inti sel yang jelas dengan nilai OD 160.630 dan sitoplasma yang jelas dengan nilai OD 149.805, sedangkan pada suhu 60°C secara mikroskopis didapatkan preparat dengan warna inti sel yang jelas dengan nilai OD 172.061, namun warna sitoplasma terlihat mulai memudar dengan nilai OD 146.398. Kesimpulan dari penelitian ini adalah terdapat pengaruh variasi suhu dan waktu pada proses deparafinisasi menggunakan VCO terhadap kualitas preparat dan terdapat pula perbedaan kualitas preparat jaringan antara xylol dengan VCO sebagai bahan deparafinisasi pewarnaan hematoksilin eosin.
