This paper develops and estimates mixture models of crop price comovements using copula functions, which allow for departures from normality during extreme market circumstances. The models also account for unique time series patterns inherent in crop price data. The paper reaches two main conclusions. First, mixture models appear to provide an easy-to-estimate approach for capturing real-life c...

Vitamin D dependent rickets (VDDR) type 2 is a very rare hereditary disease which has an autosomal recessive mode of inheritance. Patients with VDDR have mutation in the gene encoding for vitamin receptor on chromosome 12q12-q14, thus averting normal physiological action 1,25 D. It's presents developmental delay motor domain features usually first year life. Alopecia totalis frequent associatio...

We develop a new multivariate generalized ARCH (GARCH) parameterization suitable for testing the hypothesis that the optimal futures hedge ratio is constant over time, given that the joint distribution of cash and futures prices is characterized by autoregressive conditional heteroskedasticity (ARCH). The advantage of the new parameterization is that it allows for a flexible form of time-varyin...

Most of the information about the genetic composition of parathyroid tumors has been obtained by comparative genomic hybridization (CGH) and loss of heterozygosity (LOH) studies, whereas only few conventional cytogenetic investigation results are available. We have performed cytogenetic analysis of short-term cultures from 3 parathyroid adenoma tissue samples. Two cases showed a normal karyotyp...

BACKGROUND Ability of athletes in speed or endurance contests somehow is determined by inherited muscle fiber types. One of the important genes involved in sport genetics is ACTN3 that is located on chromosome 11q13-q14 and encodes α-actinin-3, which belongs to highly conserved family of α-actinin proteins. Genetic analysis of α-actinin-3 gene has showed a polymorphism R577X (rs1815739), which ...

This paper analyzes the MC use determinants taking social ties into account using data in Guatemalan Living Standard Measurement Study. It ...

BACKGROUND/AIM Pancreatic neuroendocrine tumors (PNETs) are uncommon malignancies of largely unknown pathogenesis. Observations on patients and their families can provide clues on etiology. PATIENTS AND METHODS In a medical oncology practice cohort of 2,087 patients 5 females and 2 males with PNETs have been identified. RESULTS Observations of etiologic interest have been made in 2 patients...

Lipomas are one of the most common mesenchymal neoplasms in humans. They are characterized by consistent cytogenetic aberrations involving chromosome 12 in bands q14-15. Interestingly, this region is also the site of rearrangement for other mesenchymally derived tumors. This study demonstrates that HMGI-C, an architectural factor that functions in transcriptional regulation, has been disrupted ...
