The potential use of ram horn hydrolysate (RHH) as a supplement for improvement of citric acid production by Aspergillus niger NRRL 330 was studied. For this purpose, first RHH was produced. Ram horns were hydrolyzed by treating with acid (6 N-H2SO4) and the RHH was obtained. With the addition of RH... | PMID: 14643992

Polled, or the absence of horns, is a desirable trait for many cattle breeders. However, the presence of scurs, which are small horn-like structures that are not attached to the skull, can lower the value of an animal. The scurs trait has been reported as sex influenced. Using a genome scan with 162... | PMID: 14731227

We experimentally dehorned dairy calves, less than 2 weeks of age, with (20 calves) or without (20 calves) intramuscular injections of ketoprofen. All calves received a local anesthetic (lidocaine) prior to dehorning and were dehorned with heat cauterization. Cortisol concentration was measured via... | PMID: 15025150

We present the fundamentals of DIC with an emphasis on the application to biological materials. An approach for surface preparation is described that facilitates its application to hydrated substrates. Three examples are presented that highlight the use of DIC for biomedical research. The first exam... | PMID: 15250755

We show that in an evolutionary response to sport hunting of bighorn trophy rams (Ovis canadensis) body weight and horn size have declined significantly over time. We used quantitative genetic analyses, based on a partly genetically reconstructed pedigree from a 30-year study of a wild population in... | PMID: 14668862

We present a 33 year-old patient who sustained a penetrating wound of the thoracic aorta caused by a deer horn, without any other lesions. A brief survey of the literature summarizes the epidemiology, diagnosis, surgical care and prognosis of this lesion. | PMID: 14748193

Material suspected of originating from species of Rhinoceros is frequently seized by forensic organizations investigating trade in endangered species. At present identification of the species is possible by DNA sequencing of the material, such as powdered rhinoceros horns. The unambiguous identifica... | PMID: 12969614

The inhibition of MAO-B activity and the increase of monoamines(5-HT, DA) level, the increase of RNA and protein level, and the incorporations of [3H] Uridine into RNA and [3H] Leucine into protein in liver tissue, the enhancement of SOD activity and the decrease of MDA content in brain and liver ti... | PMID: 14649202

We have performed an extensive study to determine the activity distributions of radiocesium (137Cs) and of the radioisotope 40K of potassium in the whole body of a cow. ICRP assumes that cesium and potassium are distributed homogeneously throughout the whole body of an organism. The current investig... | PMID: 12938962

OBJECTIVE: To study the optimum extraction factors of Buxueyangyan Mixture. METHOD: The orthogonal design was used to select the optimum extraction factors of Cervi Pantotrichum etc. and water extraction rate was used to evaluate the factors. The orthogonal desingn was used to study three factors in... | PMID: 15139142

We find that greater horn length, body size and good condition each independently influence a male's ability to monopolize receptive females. For males with large horns at least, this behavioural success translates into greater siring success. Consistent with sperm-competition theory, we also find t... | PMID: 12769464

The purpose of this work was to assess whether the non-steroidal anti-inflammatory drugs (NSAIDs) phenylbutazone and ketoprofen, and an adrenocorticotropic hormone (ACTH) induced cortisol surge, reduce the cortisol response which occurs when the local anaesthetic wears off in calves following dehorn... | PMID: 12204628

A hydride atomic fluorescence spectrometry has been developed for the determination of trace arsenic and mercury in medicinal animal horns. This method was simple, rapid and sensitive. The samples were digested with HNO3-HClO4(5:1), under the optimum conditions, the allowable amounts of 26 coexist e... | PMID: 12938449

We did a retrospective survey of 34 patients who sustained facial injuries after animal associated incidents and presented to three Nigerian teaching hospitals. There were 27 male (79%) and 7 female patients, whose ages ranged from 6 to 40 years. Sixteen (47%) were less than 15 years. Cows (n=14), c... | PMID: 12379192

The preparation of hard tissues such as the equine hoof horn for electron microscopic examination is very difficult. In particular the penetration of fixatives and chemicals used during fixation and embedding is a problem. The objective of this study was to find and implement an alternative method e... | PMID: 12203712

We searched our departmental files for similar cases and examined them grossly and microscopically. Four cases were identified. All occurred as solitary lesions in older women on the parietal-occipital region of the scalp. They had a growth history of up to 30 years; the women hid these horns in the... | PMID: 12023585

The very short-lived adrenaline responses in calves were attributed to dehorning-induced nociceptor input leading to sympathetic stimulation of the adrenal medulla. The longer lasting noradrenaline responses in lambs and calves were thought be due to 'wash-out' of noradrenaline from damaged tissue a... | PMID: 12054287

Dehorning caused a marked cortisol response lasting for about 7 h. Local anaesthetic reduced the plasma cortisol concentrations to control values for 5 h, after which they increased for a further 5 h. Subsequently in both groups, cortisol concentrations remained at control values until at least 24 h... | PMID: 12019704

In rural regions, with cattle breeding, open-globe injuries by cow horns are relatively common and the frequency is still the same as 50 years ago. The visual prognosis of these eyes is still guarded, but functional results have improved with the introduction of vitreous surgery. Patients who have h... | PMID: 12220001

Our data suggest a middle Miocene origin of Ceratophora with the most recent branching of recognized species occurring at the Pliocene/Pleistocene boundary. Haplotype divergence suggests that an outgroup species, Lyriocephalus scutatus, dates at least to the Pliocene. These phylogenetic results prov... | PMID: 11796034
