the effect of ascorbic acid (aa) and butylated hydroxyanisole (bha) supplementation on aflatoxicosis in broiler chickens (1 to 42 days of age) was investigated (250, 500, 1000 and 2000 ppm for aa and bha) in diet containing 1 ppm total aflatoxin (af: 76.45% afb1, 10.52% afb2, 9.89% afg1 and 3.14% afg2). a total of 300 day-old broiler chicks were divided into ten treatment groups (t1=control; t2...
The effect of ascorbic acid (AA) and butylated hydroxyanisole (BHA) supplementation on aflatoxicosis in broiler chickens (1 to 42 days of age) was investigated (250, 500, 1000 and 2000 ppm for AA and BHA) in diet containing 1 ppm total aflatoxin (AF: 76.45% AFB1, 10.52% AFB2, 9.89% AFG1 and 3.14% AFG2). A total of 300 day-old broiler chicks were divided into ten treatment groups (T1=control; T2...
Twelve anesthetized mongrel dogs underwent left thoracotomy with placement of a removable ligature around the left circumflex coronary artery. Following a 3 to 6 hour delay, ECG-gated spin-echo MRI was performed. The ligature was then removed reperfusing the heart, and after a 10-15 min period, MRI repeated. Finally, post-sacrifice images were obtained, and the hearts chemically stained for inf...
OBJECTIVE The present study assessed the maxillary dental arch changes produced by surgically assisted rapid maxillary expansion (SARME). METHODS Dental casts from 18 patients (mean age of 23.3 years) were obtained at treatment onset (T1), three months after SARME (T2) and 6 months after expansion (T3). The casts were scanned in a 3D scanner (D-250, 3Shape, Copenhagen, Denmark). Maxillary den...
Background The management of iron overload has been transformed by the use of T2* as a surrogate marker of cardiac iron loading. The presence of iron however not only changes T2*, but also T2 and T1. Recent advances make T1 mapping a possible complementary technique to T2*. Preliminary data are encouraging, but the relative advantages and disadvantages and optimal mathematical model for the rel...
BACKGROUND With the scale-up of antiretroviral therapy (ART), monitoring programme performance is needed to maximize ART efficacy and limit HIV drug resistance (HIVDR). METHODS We implemented a WHO HIVDR prospective survey protocol at three treatment centers between 2012 and 2013. Data were abstracted from patient records at ART start (T1) and after 12 months (T2). Genotyping was performed in...
To investigate the thyroid hormone metabolism in altered states of thyroid function, serum concentrations of 3, 3'-diiodothyronine (3, 3'-T2), 3', 5'-T2 and 3, 5-T2 as well as T4, T3 and rT3 were determined by specific radioimmunoassays in 17 hyperthyroid and 10 hypothyroid patients, before and during the treatment. Serum T4, T3, rT3, 3, 3'-T2 and 3', 5'-T2 concentrations were all higher in the...
A field experiment was conducted at Agricultural College & Research Institute, Tamil Nadu University, Madurai during 2021to quantify the GHG emission in puddled rice, ADT 54. The laid out Randomized Block Design with four replications treatments, T1 - SRI method of rice cultivation organic farming SOP, T2 inorganic T3 T1+BGA application @ 10 kg ha-1, T4 T2+ BGA T5 -T1+Azolla 250 T6 -T2+ Azo...
The adsorbate resulting from the potentiostatic, catalytic decomposition of methanol (0.1 M CH3OH in 0.5 M H2SO4) on a platinum black electrode has been studied via 13C nuclear magnetic resonance spectroscopy, at open cell potential. Cyclic voltammetry results indicate that coverage is a function of electrodecomposition time and potential. The spin-spin relaxation time T2 is dependent on surfac...
