Abstrak :
Diabetes melitus tipe 2 (DMT2) adalah penyakit gangguan metabolisme yang menyebabkan regulasi insulin terganggu dan dapat mengakibatkan komplikasi penyakit ginjal diabetes (PGD). Saat ini, gold standard penilaian fungsi ginjal dilakukan berdasarkan parameter eGFR dan albuminuria, tetapi kedua parameter tersebut memiliki beberapa keterbatasan. Oleh karena itu, metode baru untuk deteksi dini fungsi ginjal dapat bermanfaat dalam upaya pencarian target terapi yang lebih tepat, salah satunya melalui pendekatan metabolomik. Tujuan penelitian ini yaitu melihat perbedaan profil metabolit serum pasien DMT2 risiko rendah (n=16) dan tinggi (n=16) PGD berdasarkan klasifikasi KDIGO 2022 yang mengonsumsi metformin-glimepirid. Desain penelitian cross-sectional dengan teknik consecutive sampling dilakukan di Puskesmas Kecamatan Pasar Minggu dan RSUD Jatipadang. Sebanyak total 32 partisipan yang memenuhi kriteria inklusi dibandingkan profil metabolitnya berdasarkan kategori risiko PGD. Sampel darah, urin, serta data karakteristik dasar dan klinis dikumpulkan untuk analisis metabolomik. Analisis untargeted metabolomics dilakukan menggunakan LC/MS-QTOF dengan metode yang sudah tervalidasi. Pengolahan data dilakukan menggunakan MetaboAnalyst 5.0 dan SPSS versi 24.0. Seluruh metabolit yang terdeteksi diidentifikasi oleh database Metlin, HMDB, PubChem, dan KEGG. Tidak terdapat perbedaan bermakna pada seluruh karakteristik dasar dan klinis subjek penelitian. Terdapat perbedaan bermakna pada ekspresi metabolit antara dua kelompok sampel. Berdasarkan parameter VIP score >1; FC >1.2; p-value <0,05; AUC >0,65 yang ditetapkan, diperoleh tiga metabolit yang memiliki potensi sebagai senyawa biomarker dalam perkembangan PGD, yaitu acetyl-N-formyl-5-methoxykynurenamine (AFMK), phosphatydilinositol-4,5-bisphosphate (PIP2), dan cytidine diphosphate diacylglycerol (CDP-DAG). Berdasarkan ketiga metabolit tersebut, tiga jalur metabolisme berhasil terdeteksi dan berpotensi terlibat dalam perkembangan PGD yaitu metabolisme triptofan, metabolisme fosfatidilinositol, serta metabolisme gliserofosfolipid.  ......Type 2 diabetes mellitus (T2DM) is a metabolic disorder causing insulin regulation to be disrupted and may lead to diabetic kidney disease (DKD) complication. The current gold standard for assessing kidney function based on eGFR and albuminuria have some limitations. Therefore, a new method for assessing kidney function may be useful for a better therapeutic target discovery, such as through metabolomics approach. This study aims to compare the serum metabolite profiles of T2DM patients consuming metformin-glimepiride with low (n=16) and high (n=16) risk of DKD based on KDIGO 2022. A cross-sectional study with consecutive sampling method was carried out at Puskesmas Pasar Minggu and RSUD Jatipadang. A total of 32 participants fulfilled the inclusion criteria were compared for their metabolite profiles. Blood, urine, baseline and clinical characteristics data were collected to perform untargeted metabolomics analysis using a validated LC/MS-QTOF method. Data processing was performed using MetaboAnalyst 5.0 and SPSS 24.0. Metabolites were identified by Metlin, HMDB, PubChem, and KEGG databases. There were no significant differences among all basic and clinical characteristics of the participants. There were significant differences of metabolite expression between two sample groups. Based on the applied parameters VIP score >1; FC>1.2; p-value <0.05; AUC >0.65, three metabolites were found to have potential as biomarker in the development of DKD, namely acetyl-N-formyl-5-methoxykynurenamine (AFMK), phosphatydilinositol-4,5-bisphosphate (PIP2), and cytidine diphosphate diacylglycerol (CDP-DAG). Based on these metabolites, three metabolic pathways were detected and found to be potentially involved in the development of DKD, namely tryptophan metabolism, phosphatidylinositol metabolism, and glycerophospholipid metabolism.

Abstrak :
his book offers a comprehensive introduction to using Mathematica and the Wolfram Language for Bioinformatics. The chapters build gradually from basic concepts and the introduction of the Wolfram Language and coding paradigms in Mathematica, to detailed worked examples derived from typical research applications using Wolfram Language code. The coding examples range from basic sequence analysis, accessing genomic databases, and differential gene expression, to time series analysis of longitudinal omics experiments, multi-omics integration and building dynamic interactive bioinformatics tools using the Wolfram Language. The topics address the daily bioinformatics needs of a broad audience: experimental users looking to understand and visualize their data, beginner bioinformaticians acquiring coding expertise in providing biological research solutions, and practicing expert bioinformaticians working on omics who wish to expand their toolset to include the Wolfram Language.

Abstrak :
The book covers areas of cellular physiology and metabolism that are of interest to scientists involved in research in diabetes and metabolic diseases. Some chapters of the book are specifically research-oriented, as all the authors are actively practicing either bench or clinical research in the area. In particular, the book discusses classical aspects of cellular physiology and the metabolism of physical exercise, as well as novel topics like exercise in transplantation and exercise in beta-cell failure, which mark the frontiers of research in sport-related sciences and research.

Abstrak :
The Handbook of Single Cell Technology provides an overview of single cell manipulation, injection, lysis, and dynamics analysis with the aid of various miniaturized devices. The role of single cell analysis in system biology, proteomics, genomics, metabolomics and fluxomics, the applications of single cell analysis for bio-catalysis, metabolic and bioprocess engineering, and the future challenges for single cell analysis given its advantages and limitations are also elaborated. The respective chapters introduce readers to various approaches for single cell analysis. Further, they address the fabrication of different types of bio-micro/nano devices in the context of cutting-edge analysis and screening for e.g. cancers, HIV etc., which is beneficial for society at large. This handbook is intended for academic researchers, undergraduate and graduate students in the fields of Biomedical Engineering, Bio-nanoengineering, and Bio-micro/nano Fabrication. It can be used for courses on Bio-MEMS/Bio-NEMS, Biomicrofluidics, Biomicrofabrications, Micro/Nanofluidics, Biophysics, Single Cell Analysis, Bionanotechnology, Drug Delivery Systems and Biomedical Microdevices. Bringing together contributions from respected experts, it will also benefit researchers and practitioners in the biotechnology industry, where diseases analysis, diagnosis and drug screening continue to grow in importance.
