Cytokine Profiles in Eye Muscle Tissue and Orbital Fat Tissue from Patients with Thyroid-Associated Ophthalmopathy

The study included the progeny of three boar-sires breeds (SL - Swedish Landrace; LW - Large White and P - Pietrain). A total of 201 progeny of both sexes (93 female and 108 male castrated animals), originating from 16 boar-sires, were tested. The study included the progeny of 10 SL boar-sires (sires nuRWer: 1, 2, 3, 7, 8, 9, 15, 16, 17 and 18), progeny of 3 LW sires (sires nuRWer: 4, 5 and 6) and 3 P boar-sires (sires nuRWer 14, 19 and 20), born in four seasons (winter, spring, summer and autumn). Studies have shown that, with an mean weight of a warm carcass side of 81.20 kg, the highest mean values for ham weight (RW; 10.456 kg), mass of intermuscular fatty tissue (RINT; 0.477 kg), ham bone (RB; 0.837 kg) and muscle tissue RMT, 7,939 kg) have progeny of the sires of Pietrain breed (P) compared to SL and LW sires. In comparison to animals sired by SL and LW boars, the progeny of P sires had less skin and subcutaneous fat tissue (RSFT) by 30 and 549 grams. Studies have shown that we have progeny of sires 7 and 9 of SL breed which have the lowest LSMean values for the yield of skin and subcutaneous fat tissue (869 and 876 g), which is below the mean for breed by 364 and 357 g. In addition, when it comes to intermuscular fatty tissue, the lowest established value was recorded in the progeny of sire no. 8 of SL breed (182 g), which is by 220 g less than the general mean and by 132 g below the mean of the sire breed. The animals originating from sires n. 19 and 20 showed the highest weight of muscle tissue (RMT) (8.489 and 8.118 kg) in the ham, which is by 2.853 and 2.482 kg more meat compared to the progeny of sire no. 5 of LW breed. The total weight of the ham and the ham muscle yield were influenced by (P <0.01 and P <0.001) sire breed, sires within the breed, gender and season of birth. A very significant (P <0.001) influence of the weight of warm carcass sides on the ham weight and tissue yield was determined.

ABSTRAKRadiasi THz memiliki sifat yang membuatnya lebih menarik dan efektif dalam bidang teknik pencitraan biomedis. Hal ini dikarenakan radiasi THz tidak mengionisasi dan merusak jaringan. Penelitian ini menggunakan sampel jaringan biologis sapi yaitu jaringan kulit, lemak, tumor dan otot. Tujuan dari penelitian untuk mengetahui suatu jaringan terindikasi abnormal atau normal dengan melihat pemetaan panas yang dihasilkan dari penyerapan radiasi THz dalam jaringan biologis sapi dengan cara pemodelan. Penelitian ini menggunakan teknik komputasi biofisik dengan medel simulink-matlab. Rentang frekuensi radiasi THz yang digunakan 0,1 - 1 THz, daya 50 – 150 mW serta kerapatan daya 5 - 25 mW/mm3. Rasio dan temperatur dari masing-masing jaringan yaitu lemak 0,25 T/25 oC (T = 6,25 oC ), kulit 0,432 T/25oC (10,8 oC), otot 0,675 T/25oC (16,88 oC) dan Tumor 0,9 T/25oC (22,50 oC). Hasil penelitian menunjukkan bahwa Jaringan lemak memiliki produksi panas yang lebih kecil dan temperatur yang lebih rendah dari jaringan kulit dan otot. Hal ini dikarenakan jaringan lemak memiliki kadar air yang tinggi dengan konsentrasi yang lebih encer sehingga radiasi THz lebih banyak terserap dengan energi yang lebih cepat habis sesuai penetrasi jaringan. Kata kunci: terahertz; pemetaan panas; jaringan biologis; simulink-matlab. ABSTRACTTerahertz (THz) radiation has properties that make it more attractive and effective in the field of biomedical imaging techniques. This is because THz radiation does not ionize and damage tissue. This study used a sample of bovine biological tissue, namely skin, fat, tumor and muscle tissue. The aim of this research is to find out whether a tissue is indicated as abnormal or normal by looking at the heat mapping generated from the absorption of THz radiation in the biological tissue of cattle by means of modeling. This study uses biophysical computation techniques with the simulink-matlab method. The range of THz radiation frequency used is 0.1 - 1 THz, power 50 - 150 mW and power density 5 - 25 mW / mm3. The ratio and temperature of each tissue were fat 0.25 T / 25 oC (T = 6.25 oC), skin 0.432 T / 25oC (10.8 oC), muscle 0.675 T / 25oC (16.88 oC) and Tumor 0.9 T / 25oC (22.50 oC). The results showed that fat tissue has less heat production and a lower temperature than skin and muscle tissue. This is because the fat tissue has a high water content with a more dilute concentration so that more THz radiation is absorbed with energy that runs out faster according to tissue penetration. Keywords: terahertz; heat mapping; biological networks; simulink-matlab.
