introduction: nutritional quality of food during storage has become increasingly an important problem. the loss of some nutrients such as ascorbic acid (vitamin c) might be a critical factor for the shelf life of some products as citrus juice concentrates, since vitamin c content of citrus juices undergoes destruction during storage (plaza et al., 2011a). ascorbic acid is an important component...

stillbirth is defined as a calf death just prior to, during, or within 24 to 48 h of parturition. the exact cause of calf death in dairy cows in this period of time is unknown. the objective of this study was to investigate about the effective factors on stillbirth and also to estimate some of the genetic parameters in iranian dairy holsteins. data in the first and second lactation that have be...

The tobacco-specific carcinogenic nitrosamine, 4-(methylnitrosamino)l-(3-pyridyl)-l-butanone (NNK), is formed during the curing and proc essing of tobacco by nitrosation of nicotine. Nicotine and NNK have structural similarities, and they are both metabolized extensively by lung tissue via several steps known to require oxidative enzyme systems, such as cytochrome P450. On the other hand, nicot...

Aim This study investigates the effect of fat diet on gene expression profile in rat liver via protein-protein interaction mapping analysis. Background Nonalcoholic fatty liver disease (NAFLD) is a prevalent condition of liver in the world. This progressive metabolic disease is representative with fat accumulation in the patients' liver that can led to advance stages, namely, cirrhosis and ev...

Over the past half century, thousands of quantitative trait loci (QTL) have been identified by using animal models and plant populations. However, the none-reliability and imprecision of the genomic regions of these loci have remained the major hurdle for the identification of the causal genes for the correspondent traits. We used a none-experimental strategy of strain number reduction for test...

BACKGROUND Rare cases of birth defects after the use of methimazole (MMI) or carbimazole to treat hyperthyroidism in early pregnancy have been reported since 1972, whereas propylthiouracil (PTU) has not been considered teratogenic. Recently, two studies reported birth defects after the use of MMI in early pregnancy to affect 2-4% of exposed children, and one study also found birth defects after...

In this paper, we prove that there is an arithmetic progression of positive odd numbers for each term M of which none of five consecutive odd numbers M,M − 2,M − 4,M − 6 and M − 8 can be expressed in the form 2n ± pα, where p is a prime and n, α are nonnegative integers.

Motivating physical activity in people with chronic pain has challenges over those present in the general population. Physical activity in people with chronic pain is affected by psychological factors such as anxiety and worry about exacerbating pain through movement. Current sensing technologies that can track movement and emotional states and respond with personalised feedback can help promot...

At perceptual threshold, some stimuli are available for conscious access whereas others are not. Such threshold inputs are useful tools for investigating the events that separate conscious awareness from unconscious stimulus processing. Here, viewing unmasked, threshold-duration images was combined with recording magnetoencephalography to quantify differences among perceptual states, ranging fr...

The expression of interleukin-2 (IL-2) is a key event in T helper (Th) lymphocyte activation, controlling both, the expansion and differentiation of effector Th cells as well as the activation of regulatory T cells. We demonstrate that the strength of TCR stimulation is translated into the frequency of memory Th cells expressing IL-2 but not into the amount of IL-2 per cell. This molecular swit...
