PENGARUH PUASA RAMADAN TERHADAP MALONDIALDEHYDE, POLY (ADP RIBOSA) POLYMERASE, SIRTUIN 1, NUCLEAR RECEPTOR SUBFAMILY 1 GROUP D MEMBER 1 DAN TRANSFORMING GROWTH FACTOR BETA PADA PENYAKIT GINJAL KRONIS
Full text linkLatar Belakang: Penyakit ginjal kronis (PGK) merupakan masalah kesehatan global
dengan prevalensi yang terus meningkat. Penelitian ini bertujuan menganalisis
pengaruh puasa Ramadan terhadap biomarker penting pada pasien PGK. Metode:
Penelitian kohort prospektif dilakukan pada 30 pasien PGK stadium 1, 2, dan 3A yang
menjalani puasa Ramadan. Pengukuran kadar MDA, PARP, SIRT1, NR1D1, dan TGFβ dilakukan sebelum puasa, 2 minggu selama puasa, dan setelah puasa menggunakan
metode ELISA. Hasil: Terjadi penurunan signifikan pada kadar ureum, glukosa darah
puasa, HbA1C, dan asam urat (p<0,05). MDA dan SIRT1 menurun secara signifikan
(p<0,001), sementara PARP dan NR1D1 meningkat signifikan (p<0,001). TGF-β juga
menunjukkan penurunan. Tidak ada perubahan signifikan pada profil lipid, kreatinin,
dan albumin.
Kesimpulan: Puasa Ramadan memiliki efek signifikan pada beberapa parameter
biokimia dan marker biologis pada pasien PGK stadium awal. Perubahan ini
menunjukkan potensi perbaikan pada stres oksidatif, autofagi sel, regulasi inflamasi,
dan irama sirkadian. Penelitian lebih lanjut diperlukan untuk mengevaluasi efek jangka
panjang dan implikasi klinis dari temuan ini dalam manajemen PGK
Intoksikasi Alkohol Akibat Minuman Keras Oplosan
Full text linkThe incidence of alcoholic liquor poisoning (alcoholic liquor) in Indonesia shows a high number. One of the causes of alcohol poisoning is methanol. Methanol poisoning in Indonesia usually occurs as a result of drinking mixed alcohol liquor. It has been reported a male 23 years old with decreased consciousness after drinking oplosan alcohol suspected to contain methanol. The examination reveals that patients has metabolic acidosis, toxic optic neuropathy (TON) and erosive gastritis. Treatment was acidosis correction, prevent formation of metabolites, hemodialysis with supportive and symptomatic teraphy .

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Beyond Serum Creatinine: Urinary KIM-1 as a Predictive Biomarker for Subclinical Acute Kidney Injury and Chronic Kidney Disease Progression: A Systematic Review and Meta-Analysis
Full text linkBackground: The global burden of chronic kidney disease (CKD) is escalating, requiring earlier and more precise diagnostic modalities. Traditional reliance on serum creatinine and glomerular filtration rate (GFR) creates a significant blind spot regarding structural tubular integrity. A dangerous diagnostic window known as subclinical acute kidney injury (AKI) exists when tubular damage progresses despite preserved filtration function. This study aims to systematically analyze the diagnostic accuracy of urinary kidney injury molecule-1 (uKIM-1) in detecting subclinical injury and quantify its predictive value for CKD progression in populations where serum creatinine fails to provide an early warning.
Methods: A systematic review and meta-analysis of five pivotal studies were conducted, encompassing experimental models of ischemia-reperfusion and human cohorts involving Autosomal Dominant Polycystic Kidney Disease (ADPKD), Diabetic Nephropathy, and Contrast-Induced AKI. Data were synthesized using random-effects models to calculate Standardized Mean Differences (SMD) and pooled Hazard Ratios (HR) to assess the prognostic value of uKIM-1 for long-term renal decline.
Results: The analysis demonstrated that uKIM-1 levels remained significantly elevated during apparent functional recovery where serum creatinine had returned to baseline. In experimental models, persistent uKIM-1 elevation correlated strongly with histological evidence of interstitial fibrosis (r > 0.70). Clinical cohorts revealed that elevated KIM-1 is a robust independent predictor of progression to ESRD, with hazard ratios ranging from 1.34 to 3.30. Pooled analysis showed a Risk Ratio of 2.45 (95% CI: 1.55 – 3.88; p < 0.0001).
Conclusion: Urinary KIM-1 serves as a sensitive and specific biomarker for subclinical tubular injury, identifying the at-risk"phenotype missed by creatinine. Its persistent elevation signifies maladaptive repair and predicts the transition from AKI to CKD, supporting its clinical integration for early risk stratification
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
