Predator species identification is an important step in understanding predator-prey interactions, but predator identifications using kill site observations are often unreliable. We used molecular tools to analyse predator saliva, scat and hair from caribou calf kills in Newfoundland, Canada to identify the predator species, individual and sex. We sampled DNA from 32 carcasses using cotton swabs...

A fingerprint found at the crime scene is one of the most crucial fragments of personal identification that a person might leave behind. Apart from being every person’s unique identification mark that are ubiquitous to all, to start with, they often reveal on further examination, certain characteristics about the person that might narrow down the suspects’ pool. To identify criterions that can ...

Introduction: Forensic identification practice requires a multitude of methods for positive identification, among which the facial reconstruction occupies high place. For this to be done in best way possible, it is mandatory that each population have their own database regarding soft tissue thickness. Objective: The present research focused on creating such Romanian adult and exploring statisti...

OBJECTIVE We tested the hypothesis that olfactory function is more impaired in patients with primary progressive MS (PPMS) than that in relapsing-remitting MS (RRMS). METHODS Standardized olfactory testing was performed in 32 patients with PPMS, 32 patients with RRMS, and 32 healthy controls (HCs). Patients with olfactory dysfunction due to an alternative primary etiology were excluded. The v...

TO THE EDITOR: Joost à Campo, M.D., et al. (1) reported that a high proportion of subjects with cross-gender identification suffers from comorbidity with other psychiatric disorders and concluded that their sex reassignment will eventually lead to regret. We are sensitive to the issue that patients may regret their sex reassignment (2, 3). However, we have reason to disagree with the authors si...

We describe a cytoplasmic steroid binding protein in the chick oviduct which has intriguing characteristics. This protein binds [3H]estradiol with high affinity (Kd = 30 X 10(-9) M) and limited capacity (300 fmol/mg of cytosol protein). It sediments at 8 S in low-salt sucrose density gradients and at 4 S in high-salt gradients. Unlike the estrogen receptor, however, this protein also binds prog...

Gonadal steroids are known to influence hypothalamic functions through both genomic and non-genomic pathways. Sex hormone-binding globulin (SHBG) may act by a non-genomic mechanism independent of classical steroid receptors. Here we describe the immunocytochemical mapping of SHBG-containing neurons and nerve fibers in the human hypothalamus and infundibulum. Mass spectrometry and Western blot a...

BACKGROUND Identification with a media character is an influential factor for the effects of a media product on the recipient, but still very little is known about this cognitive process. This study investigated to what extent identification of a recipient with the suicidal protagonist of a film drama is influenced by the similarity between them in terms of sex, age, and education as well as by...

In theory, birds should control the sex ratio of the offspring they produce. In practice, we have very limited evidence to support this idea because of our difficulty in sexing nestling birds. In addition, extinction is facing an increasing number of birds. Our ability to help includes captive breeding which, again, is difficult if male and female adults cannot be recognized. Here we describe t...

A laboratory procedure for sex identification of monomorphic birds was developed using modern cytological methods of detecting chromosome abnormalities in human amniotic fluid samples. A pin feather is taken from a pre-fledging bird for tissue culture and karyotype analysis. Through this method, the sex was identified and the karyotype described of the whooping crane (Grus americana) and the Mi...
