"Latar Belakang: IGF-1 adalah growth factor yang sangat poten bukan hanya untuk pertumbuhan somatik tetapi juga pada sistem saraf pusat. Sekitar 70% IGF-1 di sirkulasi diproduksi di hati dan disekresikan ke aliran darah menuju organ target. IGF-1 memiliki peran penting dalam neurogenesis dewasa. Proses penuaan diasosiasikan dengan penurunan konsentrasi IGF-1. Kekurangan IGF-1 diasosiasikan dengan gangguan kognitif, penyakit Alzheimer, osteoporosis dan diabetes. Literatur terkini menunjukkan olahraga aerobik meningkatkan serum IGF-1, Environmental Enrichment (EE) juga meningkatkan neuron positif IGF-1. Namun, efek kombinasi kedua perlakuan ini belum banyak diobservasi. Penelitian ini bertujuan untuk mengamati efek olahraga aerobik dan EE secara kontinu pada IGF-1 di hati dan plasma.Metode: Penelitian ini merupakan studi data sekunder berdasarkan data yang diambil pada eksperimen in-vivo dengan tikus sebagai hewan uji. Dua puluh empat tikus wistar jantan umur tujuh bulan dibagi secara acak ke empat grup, Kontrol, Aerobik, EE dan Kombinasi. Perlakuan dilakukan selama 8 minggu. Setiap kelompok diuji kadar IGF-1 pada awal dan akhir eksperimen untuk plasma dan pada akhir eksperimen untuk hati. Pengujian IGF-1 menggunakan ELISA dengan kit Qayeebio (QY-E10935). Analisis data menggunakan one-way ANOVA untuk plasma dan Kruskall-Wallis untuk hati dengan program SPSS20.Hasil: Hasil uji IGF-1 plasma tidak menunjukkan perbedaan signifikan antar perlakuan (p=0.17) sementara hasil uji IGF-1 hati menunjukkan perbedaan signifikan antara perlakuan Aerobik dengan EE (p=0.006) dan antara perlakuan Aerobik dengan Kombinasi (p=0.042). Kesimpulan: Studi analisis data menggunakan 24 sampel tidak menunjukan peningkatan IGF-1 yang signifikan secara statistik di tikus dengan perlakuan kombinasi olahraga aerobik dan EE secara kontinu baik di plasma maupun di hati. Hal ini kemungkinan disebabkan oleh banyaknya interaksi IGF-1 dengan growth factors lain dan posibilitas bahwa IGF-1 bukan fator tunggal yang mempengaruhi dampak olahraga aerobik dan EE.

Introduction: IGF-1 is a potent growth factor not only for bodily growth but also in central nervous system. Around 70% of total circulating IGF-1 is produced in the liver, it is also secreted into the bloodstream to reach target tissue. IGF-1 has a vital role in adult neurogenesis. Normal aging is associated with reduced IGF-1 concenctration. IGF-1 deficiency is associated with cognitive impairment, Alzheimer’s disease, osteoporosis and diabetes. Recent literatures suggest aerobic exercise increases serum IGF-1, Environmental Enrichment (EE) also increases IGF-1 positive neurons. However, the effect of combination of these treatments to plasma and liver IGF-1 has not been observed. This study aims to examine the effect of aerobic exercise and continuous EE on plasma and liver IGF-1.

Method: This study is a secondary data research based on the data acquired in an experiment classified as in vivo experimental research using rats as subjects. Twenty-four 7-month-old month male Wistar rats are randomly divided into four groups which are Control, Aerobic Exercise, Environmental Enrichment and Combination group. The duration of experiment is 8 weeks. Every group has its plasma IGF-1 measured before and after the experiment and after the experiment for liver IGF- 1. IGF-1 plasma and liver levels are analyzed using ELISA method with Qayeebio (QYE10935) kit. The data is analyzed using one-way ANOVA for the plasma and Kruskall- Wallis for the liver using SPSS20 software.

Results: There’s no significant statistical difference between groups in plasma IGF-1 (p=0.17) meanwhile there’s statistically significant difference between Aerobic and EE groups (p=0.006) and between Aerobic and Combination groups (p=0.042).

Conclusion: Study data analysis using 24 samples did not show statistically significant increase of IGF-1 levels in rats treated with combination of aerobic exercise and continuous environmental enrichment both in plasma and liver. This may suggest the versatility and multiple interaction of IGF-1 and other growth factors and indicating that IGF-1 is not the sole growth factors/ substance mediating the effect of aerobic exercise and environmental enrichment."

"Latar Belakang: BDNF adalah anggota keluarga neurotrophin dari growth factors, ditemukan aktif pada korteks, basal forebrain, dan hipokampus. BDNF berkerja pada neuron sistem saraf pusat dan perifer untuk mendukung neurogenesis dan kelangsungan hidup neuron dan sinaps yang sudah ada. Seiring bertambahnya usia manusia, BDNF akan menurun lalu menyebabkan degenerasi neuron dan penurunan fungsi memori. Kekurangan BDNF dapat menyebabkan Dementia dan penyakit Alzheimer. Untuk mencegah penyakit neurodegeneratif, literatur mengajukan untuk meningkatkan kadar BDNF melalui olahraga aerobik dan Environmental Enrichment (EE) di usia dekade kedua. Penelitian ini bertujuan untuk mengamati efek kombinasi EE dan olahraga aerobik pada kadar BDNF.Metode: Penelitian ini merupakan eksperimen in-vivo dengan binatang sebagai hewan uji, yaitu tikus wistar jantan usia tujuh bulan dengan berat 300- 400 gram. Dua puluh empat tikus dibagi secara acak ke empat grup, Kontrol, Aerobik, EE dan Kombinasi. Durasi eksperimen adalah 8 minggu. Setiap kelompok menjalani pengambilan darah perifer pada awal dan akhir eksperimen. Uji Bradford dilakukan untuk menghitung konsentrasi total protein dalam darah, dan konsentrasi BDNF pada plasma dihitung menggunakan teknik ELISA dengan kit Qayeebio (QY-E11168). Analisis data menggunakan one-way ANOVA dan analisis post-hoc. Fungsi memori spasial diuji dengan Y-Maze spontaneous alternation. Korelasi antara kadar BDNF plasma dengan fungsi memori spasial diukur menggunakan uji korelasi Pearson.Hasil: Kadar BDNF menunjukkan perbedaan signifikan secara statistik antar kelompok di minggu ke-8 (p=.001). Signifikansi data ditemukan antara kelompok Kontrol-EE (p=.049), Kontrol- Kombinasi (p=.000), Aerobik-Kombinasi (p=.001), and EE-Kombinasi (p=.013). Terdapat korelasi signifikan antara kadar BDNF plasma dengan fungsi memori minggu ke-8 (p=.031), dengan tingkat korelasi antara kedua faktor bernilai sedang (r=.440).Kesimpulan: Analisis data menunjukan peningkatan BDNF yang signifikan secara statistik di kelompok Kombinasi, EE, dan Aerobik dari paling tinggi hingga ke paling rendah. Maka, kombinasi EE dan olahraga aerobik merupakan metode yang efektif untuk peningkatan fungsi memori serta pencegahan degenerasi saraf.

Introduction: BDNF is a member of neurothropin family of growth factors, found active in the cortex, basal forebrain, and hippocampus of the brain. BDNF acts on the neurons of the central and peripheral nervous system to promote neurogenesis and aid the survival of the existing neurons and synapses. As humans age, BDNF depletes causing neurodegeneration to occur and memory functions to progressively decrease. A deficiency in BDNF may lead to Dementia and Alzheimer’s disease. In order to prevent neurodegenerative diseases, literatures propose to increase BDNF level in the second decade by undergoing aerobic exercise and Environmental Enrichment (EE). This study aims to investigate the effect of combining EE and aerobic exercise on BDNF level.

Method: This study is an in-vivo experimental research using animals as test subjects, specifically 7-month old adult male Wistar rats with weight ranging from 300-400 grams. Twenty-four rats are divided randomly into four groups, they are Control, Aerobic, EE and Combination group. The duration of the experiment is 8 weeks. Each group undergoes peripheral blood withdrawal pre- and post-experiment. Bradford test is performed to measure total protein concentration in the blood, and concentration of BDNF in plasma is measured using ELISA technique with Qayeebio (QY-E11168). The data is analyzed by one-way ANOVA and post-hoc analysis. Spatial memory function is tested using Y-maze spontaneous alternation test. The correlation between plasma BDNF level and spatial memory function is assessed using Pearson correlation test.

Results: There is a statistically significant difference between the groups in week 8 (p=.001). Other statistical significances were found between Control-EE (p=.049), Control-Combination (p=.000), Aerobic Exercise-Combination (p=.001), and EE-Combination (p=.013). There is a statistical significance correlation between plasma BDNF concentration and memory test week 8 (p=.031) and the correlation is classified as moderate correlation (r=.440).

Conclusion: Data analysis demonstrates statistically significant increase in Combination, EE, and Aerobic groups, from highest to lowest. Thus, combining both EE and aerobic exercise is an effective method to promote memory functions and prevent neural degeneration."

"Latar Belakang: Memori sangat berperan penting dalam proses kehidupan. Seiring dengan bertambahnya usia, fungsi memori akan mengalami penurunan karena proses neurodegenerasi. Stimulus eksternal baik latihan fisik aerobik maupun environmental enrichment EE mampu memperlambat terjadinya neurodegenerasi dengan meningkatkan neuroplastisitas melalui ekspresi berbagai protein baik protein sinaptik maupun growth factor seperti insulin like growth factor 1 IGF-1 dan fibroblast growth factor 2 FGF-2 . Pemberian kombinasi latihan aerobik dan environmental enrichment kontinyu dan pengaruhnya pada ekspresi IGF-1 dan FGF-2 yang diharapkan mampu meningkatkan fungsi memori belum dilakukan pada penelitian sebelumnya.Bahan dan Metode: Penelitian ini merupakan penelitian eksperimental pada 24 tikus Wistar jantan Rattus norvegicus, 300-400 gram, usia 7-8 bulan , dibagi secara acak ke dalam 4 kelompok: kontrol K , latihan aerobik A , Environmental Enrichment kontinyu EE , dan kombinasi latihan aerobik dan Environmental Enrichment kontinyu A-EE .Hasil: Kelompok kombinasi latihan aerobik dan environmental enrichment A-EE menunjukkan fungsi memori spasial tikus terbaik. Namun ekspresi IGF-1 dan FGF-2 hipokampus pada kelompok A-EE tidak lebih tinggi dari kelompok lain. Selain itu, ekspresi FGF-2 hipokampus berkorelasi positif dengan kekuatan sedang dengan fungsi memori, sedangkan IGF-1 hipokampus berkorelasi negatif dengan kekuatan lemah dengan fungsi memori.Kesimpulan: Peningkatan fungsi memori pada kelompok kombinasi merupakan hasil induksi ekspresi berbagai protein di hipokampus, namun jalur utama yang meningkatkan fungsi memori bukanlah melalui peningkatan ekspresi IGF-1 dan FGF-2 di hipokampus.

Background Memory plays an important role in life. Memory declines with age through the process of neurodegeneration. External stimuli such as aerobic exercise and environmental enrichment EE can delay neurodegeneration by improving neuroplasticity via expression of various synaptic proteins and growth factors such as insulin like growth factor 1 IGF 1 and fibroblast growth factor 2 FGF 2 . Combination treatment of aerobic exercise and continuous environmental enrichment and their effect on the expression of IGF 1 and FGF 2 which were expected to improve memory function has not been studied previously.Materials and Methods This is an experimental research using 24 male Wistar rats Rattus norvergicus, 300 400 g, age 7 8 months divided randomly into 4 groups control C , aerobic exercise A , continuous environmental enrichment EE , and combination of aerobic exercise and continuous environmental enrichment A EE .Results Combination of aerobic exercise and environmental enrichment group A EE showed the best improvement in rats rsquo spatial memory. But their hippocampal IGF 1 and FGF 2 expression were not higher than other groups. There was positive correlation between hippocampal FGF 2 and memory function, but there was negative correlation between hippocampal IGF 1 and memory function.Conclussions Improvement in memory function in combination group is a result of induction of various protein expression in the hippocampus, but the primary pathway of memory function improvement is not through the hippocampal IGF 1 and FGF 2 expression.

" adalah salah satu penyebab penurunan performa fisik pada seseorang yang melakukan program latihan fisik jangka panjang. Kondisi overtraining dihubungkan dengan gangguan dalam regenerasi sel tubuh. Insulin-like growth factor-I (IGF-I) adalah protein yang menstimulasi pertumbuhan dan proliferasi sel. IGF-I bekerja dalam regulasi aksis GH/IGF, dimana kerja IGF dipengaruhi oleh growth hormone (GH) dan insulin-like growth factor binding protein-3 (IGFBP-3). Penelitian ini bertujuan untuk mengetahui respons tubuh terhadap latihan fisik aerobik overtraining dengan menganalisa kadar GH, IGF-I, dan IGFBP-3, mengingat hormon dan protein ini berperan dalam regenerasi sel tubuh, khususnya otot rangka. Subjek penelitian adalah 19 ekor tikus putih jantan galur Wistar (berusia 8-10 minggu, berat 150-250 gr) yang dibagi menjadi 3 kelompok (satu kelompok kontrol dan dua kelompok yaitu kelompok aerobik dan kelompok aerobik overtraining yang diberikan perlakuan masing-masing selama 11 minggu). Perlakuan latihan fisik aerobik dan aerobik overtraining dilakukan dengan Animal treadmill L-6000 sebanyak lima hari dalam seminggu. Setelah hari terakhir perlakuan, seluruh hewan coba dikorbankan. Serum darah diambil dengan cara pungsi jantung. Kadar GH, IGF-I, dan IGFBP-3 dalam serum diukur dengan metode ELISA dan data hasil penelitian dianalisis dengan one way ANOVA dan dilanjutkan dengan uji Post Hoc. Hasil pemeriksaan ELISA menunjukkan kadar IGFBP-3 yang lebih rendah secara signifikan pada kelompok aerobik overtraining dibandingkan dengan kelompok aerobik, sementara tidak ada perbedaan kadar GH dan IGF-I pada ketiga kelompok. Kadar IGFBP-3 dalam serum dapat dipertimbangkan sebagai penanda biologis kondisi overtraining.

Overtraining is one of the causes of decline in physical performance in long-term physical exercise program. Overtraining is associated with impaired regeneration of body cells. Insulin-like growth factor-I (IGF-I) is a stimulator of cell growth and proliferation. IGF act based on the GH/IGF axis, which mean IGF-I act is regulated by growth hormone (GH) and insulin-like growth factor binding protein-3 (IGFBP-3). This study purpose is to determine the body's response to aerobic overtraining exercise by analyzing the levels of growth hormone (GH), insulin-like growth factor-I (IGF-I), and insulin-like growth factor binding protein-3 (IGFBP-3) as those hormone and proteins play a role in the regeneration of body cells, especially skeletal muscle cells. Subjects were 19 white male rats of the Wistar strain (8-10 weeks old, weight: 150-250 g) were divided into 3 groups (one control group and two groups of aerobic and aerobic overtraining group both were given treatment for 11 weeks). Aerobic exercise and aerobic overtraining exercise treatment were conducted five days a week using Animal treadmill L-6000. After the last day of treatment, all experimental animals were sacrificed. Blood serum collected by cardiac puncture. Levels of GH, IGF-I and IGFBP-3 in serum were measured by ELISA. The data were analyzed by one-way ANOVA followed by post hoc test. ELISA results showed significant lower levels of IGFBP-3 in aerobic overtraining group compared to the aerobic group, while there was no difference in the levels of GH and IGF-I in all groups. IGFBP-3 levels in the serum may be a suitable as biological markers for overtraining condition."

Background : Stunting is a manifestation of chronic malnutrition which is characterized by a lower height than the individual's age standard. One of the primary cause of stunting is the lack of nutritional intake. Lack of nutritional intake can cause reduced Hb and IGF-1 levels. Lack of nutritional intake can also interfere with the process of growth and development of the teeth which can affect the timing of tooth eruption. An analysis is needed to see the relationship between stunting and levels of Hb, IGF-1, and the timing of tooth eruption. Objective : To analyze the relationship between Hb levels, IGF-1 levels, and the timing of tooth eruption with stunting. Method : Literature research was carried out using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines on three electronic databases, namely: PubMed, EBSCO, and SCOPUS. The quality of the literature was assessed using the QUADAS-2 tool. Results : There are 27 articles that were selected based on predetermined inclusion and exclusion criteria. 19 articles state that there is a relationship between Hb levels and stunting, where stunted children are more likely to have low Hb levels (anemia). 4 article states that there is a relationship between IGF-1 levels and stunting, where stunted children have lower IGF-1 levels compared to non-stunted children. 3 The article states that there is a relationship between stunting and tooth eruption, where stunted children experience delays in tooth eruption. 1 article states that there is no relationship between stunting and dental growth and development Conclusion : There is a positive correlation between stunting and Hb and IGF-1 levels. The correlation between stunting and tooth eruption cannot be determined with certainty."

"Latar belakang: EE dan/atau latihan fisik dapat meningkatkan memori spasial dan menginduksi peningkatan ekspresi Brain-derived neurotrophic factor (BDNF) pada hipokampus tikus Wistar jantan usia 7 bulan. BDNF berikatan dengan reseptor tropomyosin receptor kinase B (TrkB) menyebabkan TrKB terfosforilasi, menghasilkan perekrutan protein yang mengaktifkan tiga kaskade transduksi sinyal. BDNF dapat meningkatkan kadar dan aktivitas reseptor NMDA sehingga terjadi perubahan jangka panjang pada aktivitas sinaps. Belum diketahui bagaimana pengaruh pemberian kombinasi EE dan latihan aerobik terhadap ekspresi pTrkB dan pNMDAR.Tujuan: Menganalisis ekspresi reseptor pTrkB dan ekspresi pNMDAR yang dipicu oleh persinyalan BDNF pada hipokampus tikus yang diberikan model EE dan/atau latihan fisik aerobik.Metode: Penelitian eksperimental menggunakan 24 tikus Wistar jantan usia 7 bulan, berat badan 250–350 gr, dibagi menjadi 4 kelompok: Kontrol (K), Aerobik (A) diberi latihan fisik 5x/mimggu treadmill kecepatan 20 m/menit 30 menit/hari, EE, dan kombinasi latihan fisik EE (AEE). Perlakuan diberikan selama 8 minggu dan dilakukan pengukuran ekpresi pTrkB dan pNMDAR dengan western blot, memori spasial diukur dengan forced alteration Y-maze.Hasil: Fosforilasi TrkB pada situs Tyr705 dan fosforilasi NMDA pada situs Tyr 1336 kelompok kombinasi lebih baik dari kontrol namun peningkatan tidak bermakna secara statistik. Fungsi memori spasial jangka pendek kelompok EE lebih baik daripada kelompok kontrol.Kesimpulan: EE kontinu dapat meningkatkan fungsi memori spasial jangka pendek tikus, kombinasi EE dan latihan aerobik cenderung meningkatkan pTrkB dan pNMDAR namun tidak bermakna secara statistik.

Background: EE and/or aerobic exercise can improve spatial memory and induce increased expression of Brain-derived neurotrophic factor (BDNF) in the hippocampus of male Wistar rats aged 7 months. BDNF binds to the tropomyosin receptor kinase B (TrkB) induce phosphorilating of TrKB, resulting the recruitment of a protein that activates three signal transduction cascades. BDNF can increase the levels and activity of the NMDA receptors, resulting in long-term changes in synaptic activity. The effect of combination of continuous EE and aerobic exercise on hippocampus pTrkB and pNMDAR expression is not yet known.

Objective: To analyze pTrkB receptor expression and pNMDAR expression induced by BDNF signaling in the hippocampus of mice given EE models and / or aerobic exercise.

Methods: Experimental study using 24 male Wistar rats aged 7 months, weight 250–350 gr, divided into 4 groups: Control (K), Aerobics (A) given 5x physical exercise/week with treadmill speed 20 m/min 30 minutes/day, EE, combination of physical exercise and EE (AEE). Treatment was administered for 8 weeks and the phosphorylation of TrkB and NMDA receptors measured with Western blot, spatial memory measured by forced alteration of Y-maze.

Result:The combination group of TrkB phosphorylation at Tyr705 site and NMDA phosphorylation at the Tyr 1336 site were better than the control group but the increase was not statistically significant. The EE group's short-term spatial memory function was better than the control group.

Conclusion: Continuous EE can improve mouse short-term spatial memory function, combination of EE and aerobic exercise tends to increase pTrkB and pNMDAR but not statistically significant."

ABSTRACTBackground: Diabetes mellitus (DM) patients are at increased risk for fracture due to the decrease in bone quality and strength. Bone Mineral Densitometry (BMD) measurement in T2DM cannot depict bone fragility (T2DM) because they are shown to be normal or increased results. Previous studies have shown a decrease in markers of bone formation (P1NP) in premenopausal women with T2DM compered non-DM. IGF-1 and sclerostin are factors that influence the differentiation and maturation of osteoblasts in bone formation and their profiles are not currently known in patients with premenopausal women with diabetes. Objective: To determine and compare serum IGF-1 and serum sclerostin levels between premenopausal women T2DM and non-DM. Method: A cross-sectional study was conducted in August 2018 and involved 80 premenopausal women consisting of 40 DMT2 and 40 non-DM subjects. Serum IGF-1 and serum sclerostin were examined using an enzyme-linked immunosorbent assay (ELISA) method. Results: Median (interquarter range) serum IGF-1 in T2DM is 40.6 ng/ml (11-110 ng/ml) vs. 42.75 ng/ml (10-65 ng/ml) in non-DM (p=0.900). Mean serum sclerostin level in T2DM is 132.05 ng/ml (SB 41.54 ng/ml) vs. 96.03 ng/ml (SB 43.66 ng/ml) in not DM (p<0.001). Conclusion: There was no difference in serum IGF-1 levels between premenopausal women with T2DM and non-DM. There were significant differences in serum sclerostin between premenopausal women with T2DM and non-DM."

"Penurunan memori dikaitkan dengan penurunan kemampuan neuroplastisitas. Penurunan tersebut terjadi seiring penuaan dan dimulai sejak usia dewasa muda. Fungsi memori yang terkait dengan plastisitas sinaps dipengaruhi oleh pengalaman dan proses belajar. Oleh karena itu, diperlukan upaya pencegahan gangguan memori sejak dini. Riset pada hewan coba menunjukkan sistem saraf pusat SSP memberikan respons terhadap stimulus eksternal yang bertanggung jawab terhadap plastisitas fungsional. Bukti pertama yang menunjukan faktor ekstrinsik dapat memodulasi plastisitas struktur hipokampus pada mamalia didapat dari berbagai studi yang memaparkan mencit pada Enviromental Enrichment EE. Peningkatan pemelajaran dan memori juga diinduksi oleh latihan fisik yang berhubungan langsung dengan plastisitas sinaps. Penelitian ini bertujuan untuk membandingkan perngaruh latihan aerobik, penerapan EE dan kombinasi keduanya terhadap fungsi memori. Merupakan studi ekperimental in vivo selama 6 minggu, menggunakan 20 ekor tikus wistar jantan usia 6 bulan yang dibagi secara acak menjadi 4 kelompok yaitu: 1 kelompok kontrol K , 2 kelompok aerobik, 3 kelompok EE, 4 kelompok kombinasi.

The memory declining is associated with the decreasing of neuroplasticity. The declining occurs with aging and started since early adulthood. Therefore, it is necessary to prevent memory and neuroplasticity disorders since early stage. Research shows the central nervous system CNS responds to external stimuli responsible for functional plasticity. The first evidence showing that extrinsic factors can modulate hippocampal structural plasticity in rodents arose from studies exposing mice to an enriched environment. Enhance in learning and memory also occurs by activity dependent by physical exercise induction. This study aim to determine the influence of physical exercise, environmental enrichment and the combination of both stimuli on spatial memory function. The research was an experimental in vivo for 6 weeks, using 20 male Wistar rats age 6 months old randomly divided into 4 groups 1 control group C, 2 aerobic group A, 3 EE group EE and 4 combination group AE EE. Water E Maze apparatus were used to assess the spatial memory function of male Wistar rats measured at week 0,2 ,4 and 6. Protein expression was examined with immunohistochemistry technique. The research showed that combination of physical exercise and Environmental Enrichment EE increase the expression of neuroligin 1 and PSD 95 followed by improvement on memory function of male Wistar rats."
