Xeroderma Pigmentosum (XP) is a rare autosomal recessive disorder characterized by an extreme sensitivity to UV rays from sunlight, a high incidence of skin cancer and occasional neurological symptoms. XP, primarily defined as a DNA repair syndrome, has been found associated with defects in the Nucleotide Excision Repair (NER) pathway, and more recently by transcriptional deregulation. XP results from mutations in eight genes (XPA to XPG and XPV) coding for proteins involved in NER.

Hormones belong to metabolic factors that control and regulate feed intake in ruminants and rats. Estrogen depresses feed intake. Insulin is an important hormone possessing both long-term and short-term effects on ruminant nutrient partitioning and feed intake. Insulin is associated with overconsumption in rats. The role of glucagon in feed intake regulation in ruminants has not been thoroughly described. Some evidence exists that exogenous glucagon reduces feed intake in sheep. Intravenous glucagon induced satiety in humans. Intraperitoneal glucagon has not affected feed intake in rats. Research is needed to elucidate how to manipulate animal and human endocrinology to optimize feeding strategies and systems in food-producing animals and to improve human health.

Intrinsic noise embedded in stochastic gene regulation due to low copy number of species has been studied using the approach of theoretical modeling and computational simulation, including the standard methods of stochastic simulation algorithm (SSA) and linear noise approximation (LNA). At average cell level, Hill functions are widely used as a compact format to represent gene regulation involving multi-transcription-factor binding and cooperativity. Heuristic SSA and LNA methods (hSSA and hLNA) have been applied to study stochastic models employing Hill functions. It is however unclear which modeling and simulation method is suitable to characterize intrinsic noise of Hill-type gene regulation with sufficient accuracy and computational efficiency. In this work, we perform noise analysis of two gene regulatory models represented by second-order activating and inhibitory Hill functions, seeking to evaluate the performance of five existing noise modeling methods.

New analytic methods based on nonlinear system theory have been developed to characterize the nonlinear features in HR dynamics. It is known from long time series (24h ECG recordings) that patients with chronic heart failure or stable coronary heart disease have altered fractal organization in heartbeat dynamics. During such long-time series, many confounding could limit the assessment of autonomic functions.

The DNA mismatch repair (MMR) system is necessary for the maintenance of genomic stability. The MMR system promotes genomic fidelity by repairing base-base mismatches, insertion-deletion loops (IDLs) and heterologies generated during DNA replication and recombination.
