CPU, SMP and GPU implementations of Nohalo level 1, a fast co-convex antialiasing image resampler
No full textThis article introduces Nohalo level 1 (“Nohalo”), the simplest member of a family of image resamplers which straighten diagonal interfaces without adding noticeable nonlinear artifacts. Nohalo is interpolatory, co-monotone, coconvex, antialiasing, local average preserving, continuous, and exact on linears. Like many edge-enhancing methods, Nohalo has two main stages: first, nonlinear interpolation is used to create a double-density version of the original image; this doubledensity image is then resampled with bilinear interpolation. Nohalo is especially suited for GPU computing because the nonlinear slopes can be computed once and stored in a low bit-depth texture without rounding error, because the final bilinear stage can be performed in hardware, and because monotonicity allows full use of the texture’s dynamic range. Demand-driven implementations for CPUs and SMPs are more complex, and require extra work to fix bottlenecks. Efficient implementations of the minmod function are key to performance. Three implementations of Nohalo are presented and benchmarked: a CPU version in C for the graphics library GEGL, an SMP version in C++ for the graphics library VIPS and a GPU version in HLSL for DirectX. The GPU implementation is branch-free thanks to the discovery of a simple formula for the pixel values of the double density image. Branches are eliminated in the demand-driven C/C++ implementations by reflecting, if needed, Nohalo’s 12-point stencil with pointer shifts. Overall, Nohalo is not much slower than standard bicubic resamplers. Compared to twenty-three alternatives in tests involving the re-enlargement of images downsampled with nearest neighbour, Nohalo gets the best PSNRs
GAMBARAN PENDERITA SIROSIS HEPATIS BERDASARKAN KLASIFIKASI CHILD TURCOTTE PUGH DAN PENYEBAB KEMATIAN DI RSUP DR. M. DJAMIL PADANG
No full textSirosis hepatis merupakan penyakit hati kronis yang ditandai dengan distorsi arsitektur hepar dan pembentukan nodulus regeneratif pada stadium akhir fibrosis hepatik yang berlangsung progresif. Berat ringannya penyakit sirosis hepatis dapat dinilai dengan menggunakan klasifikasi Child Turcotte Pugh. Angka kematian penyakit sirosis hepatis, tinggi karena komplikasinya. Penelitian ini dilakukan untuk mengetahui gambaran penderita sirosis hepatis berdasarkan klasifikasi Child Turcotte Pugh dan penyebab kematiannya.
Penelitian ini menggunakan metode deskriptif dengan desain retrospektif. Sampel penelitian ini berjumlah 135 orang penderita sirosis hepatis yang meninggal di Bagian Penyakit Dalam RSUP Dr. M. Djamil Padang periode 2015 – 2017.
Dari hasil penelitian didapatkan frekuensi klasifikasi Child Turcotte Pugh pada pasien sirosis yang meninggal adalah CTP-C sebanyak 90,4%, CTP-B sebanyak 9,6% dan tidak ada pasien sirosis hepatis dengan CTP-A yang meninggal dunia. Frekuensi penyebab pasien sirosis hepatis meninggal yang terbanyak karena ensefalopati hepatikum 48,1%, diikuti sepsis akibat peritonitis bakterial spontan 34,1%, perdarahan varises esofagus 13,3%, hepatocellular carcinoma 3,7%, infeksi lain 0,8% dan tidak ditemukan pasien sirosis hepatis yang meninggal karena sindroma hepatorenal.
Kesimpulan penelitian ini adalah frekuensi klasifikasi Child Turcotte Pugh pada pasien sirosis hepatis meninggal yang terbanyak adalah CTP-C dan ensefalopati hepatikum merupakan penyebab meninggal tertinggi pada pasien sirosis hapatis.

PERBEDAAN KADAR HYPOXIA INDUCIBLE FACTOR 1 ALPHA SERUM DAN ALKALINE PHOSPHATASE SERUM BERDASARKAN KLASIFIKASI CHILD-TURCOTTE-PUGH PADA PASIEN SIROSIS HATI
No full textPendahuluan
Hipoksia sangat berperan dalam patogenesis sirosis hati. Hypoxia Inducible Factor 1 Alpha adalah regulator transkripsi yang memiliki efek respon homeostasis terhadap tekanan oksigen yang rendah dan telah diidentifikasi sebagai mediator kunci angiogenesis, inflamasi, dan metabolisme. Peningkatan Hypoxia Inducible Factor 1 Alpha dalam sitoplasma sel hati berpengaruh terhadap nukleus sel hati yang ditandai dengan peningkatan Alkaline Phosphatase. Klasifikasi Child-Turcotte-Pugh dapat menilai berat penyakit pasien sirosis hati. Oleh karena tingginya faktor risiko kematian pasien sirosis hati, maka penelitian ini bertujuan untuk mengetahui perbedaan kadar Hypoxia Inducible Factor 1 Alpha dan Alkaline Phosphatase berdasarkan klasifikasi Child-Turcotte-Pugh pada pasien sirosis hati.
Metode
Penelitian observational analitik dengan pendekatan cross sectional di Instalasi Rawat Inap dan Rawat Jalan Ilmu Penyakit Dalam RSUP Dr. M. Djamil Padang selama 6 bulan. Sampel dipilih secara consecutive sampling, dengan total 39 orang yang terdiri dari 13 orang pasien Child-Turcotte-Pugh A, 13 orang pasien Child-Turcotte-Pugh B dan 13 orang pasien Child-Turcotte-Pugh C. Kadar HIF-1α serum diperiksa dengan metode ELISA. Kadar ALP diperiksa melalui kimia klinik. Hasil yang diperoleh dianalisis secara statistik untuk melihat perbedaan antara ketiga kelompok.
Hasil
Kadar HIF-1α serum pada pasien Child-Turcotte-Pugh C lebih tinggi dibandingkan pasien Child-Turcotte-Pugh B dan Child-Turcotte-Pugh A dan berdasarkan uji Kruskal-Wallis tidak terdapat perbedaan bermakna secara statistik pada ketiga kelompok (p>0.05). Kadar ALP serum pasien Child-Turcotte-Pugh C lebih tinggi dibandingkan pasien Child-Turcotte-Pugh B dan Child-Turcotte-Pugh A dan berdasarkan uji Kruskal-Wallis terdapat perbedaan bermakna secara statistik pada ketiga kelompok (p<0.05).
Diskusi
Tidak terdapat perbedaan bermakna kadar HIF-1α, terdapat perbedaan bermakna kadar ALP pada pasien sirosis hati dengan Child-Turcotte-Pugh A, B dan C
Study of Serum Uric Acid In Liver Cirrhosis and Its Correlation with Child Turcotte Pugh Score
No full textBACKGROUND: Cirrhosis cannot be accurately diagnosed by a serologic test. Even though aberrant biochemical patterns in combination with the clinical picture can point to certain liver illnesses, liver function tests may not always accurately reflect hepatic function. Hyperuricemia was found to be a risk factor for liver diseases. So, this study is an opportunity to determine serum uric acid level in liver cirrhosis and its correlation with Child Turcotte Pugh score.
AIM OF THE STUDY:
To study serum uric acid level in liver cirrhosis and its correlation with Child Turcotte Pugh score.
OBJECTIVES:
1. To determine serum uric acid level and Child Turcotte Pugh score among patients with liver cirrhosis.
2. To study the correlation between serum uric acid level and Child Turcotte Pugh score among patients with liver cirrhosis.
METHODS: A prospective study among patients with liver cirrhosis was conducted in a tertiary care centre with eight samples using simple random sampling. Their serum uric acid and CTP score was estimated and analysed using descriptive and inferential statistics by SPSS software.
RESULTS: 36.3% of patients had Class A score, 31.3% had Class B score and 32.5% of them had Class C scores. The mean uric acid value was 5.621+1.861 mg/dL ranging from 3.4 — 10.9.
There was a significant (0.0001) positive correlation (r value 0.642) between serum uric acid and Child Turcotte Pugh score among patients with liver cirrhosis.
CONCLUSION: Child Pugh score increases together with serum uric acid levels, suggesting that uric acid estimate may be a useful and affordable diagnostic marker for assessing the degree of liver cirrhosis
Data from: Demographic responses underlying eco-evolutionary dynamics as revealed with inverse modelling
No full textData from a field experiment in which the dynamics of green peach aphid (Myzus persicae)
populations consisting of one clone (non-evolving) were compared to the dynamics of populations
consisting of two clones (potentially evolving). A total of three aphid clones were used, which were
all tested individually and in each combination. At the start of the experiment, 20 third-instar
individuals were placed on a caged host plant. For half of the populations, cages were removed at
day 13, allowing competitors to access the plants. Rapid evolutionary responses were observed,
which increased population growth rates by 33% to 42% compared to non-evolving populations.
These results have been published in Turcotte, Reznick & Hare (Ecology Letters, 2011). Data have been reanalyzed
to estimate which demographic rates were underlying different dynamics among clones, and
between non-evolving and evolving populations, making use of changes in stage structure through
time. These results have been published in Bruijning, Jongejans & Turcotte (Journal of Animal Ecology, forthcoming)
