The objectives of this study were to investigate and compare the responses of atrial natriuretic peptide (ANP) and B-type natriuretic peptide (BNP) in the circulation of hydrated, dehydrated, and dehydrated losartan - treated camels; and to document the cardiac storage form of B-type natriuretic peptide in the camel heart. Eighteen male camels were used in the study: control or hydrated camels ...

The effect of different levels of osmolality and pH of lactose extender on the viability of Bactrian camelspermatozoa was investigated. Semen was collected from 10 Bactrian camel bulls using modified bovineartificial vagina. In experiment I, the extenders consisted of 9, 10, 11, 12 and 13% lactose with respectiveosmolalities of 290, 333, 350, 376 and 419 mOsm/kg and the pH of 6.9. In experiment...

The Middle East respiratory syndrome coronavirus (MERS-CoV) was first described in September 2012 and to date 86 deaths from a total of 206 cases of MERS-CoV infection have been reported to the WHO. Camels have been implicated as the reservoir of MERS-CoV, but the exact source and mode of transmission for most patients remain unknown. During a 3 month period, June to August 2013, there were 12 ...

We have investigated a recently proposed halo-based model, Camelus, for predicting weak-lensing peak counts, and compared its results over a collection of 162 cosmologies with those from N-body simulations. While counts from both models agree for peaks with S/N > 1 (where S/N is the ratio of the peak height to the r.m.s. shape noise), we find ≈ 50% fewer counts for peaks near S/N = 0 and signif...

The present study has disclosed for the first time the distribution of cytokeratin (CK) and  smooth muscle actin (SMA) in the accessory genital glands of camel. In prostate, CK was localized in the cytoplasm of columnar cells of secretory acini and in the scanty cytoplasm of basal cells. Conversely, no expression was seen in the capsule, fibromuscular septa, and blood vessels. In the ampulla ...

We evaluated the effects of selection on the molecular evolution of the functional domains of the mammalian cytochrome b gene as it relates to physicochemical properties shown to correlate with rates of amino acid replacement. Two groups of mammals were considered: pocket gophers of the rodent family Geomyidae, and cetaceans and ungulates of the monophyletic taxon Cetartopdactyla. Several chara...

To the Editor: Hepatitis E virus (HEV) is a member of the family Hepeviridae, genus Orthohepevirus, which comprises 4 species, Orthohepevirus A–D. Orthohepevirus A contains 7 genotypes (HEV1–7) (1,2). HEV1 and HEV2 infect humans only; HEV3, HEV4, and HEV7 can infect humans and other mammals; and HEV5 and HEV6 have been detected in animals only. Worldwide, HEV is the most common cause of acute v...

BACKGROUND Reproductive biotechnologies in dromedary camel (Camelus dromedarius) are less developed than in other livestock species. The in vitro maturation (IVM) technology is a fundamental step for in vitro embryo production (IVP), and its optimization could represent a way to increase the success rate of IVP. The aim of the present study was to investigate the bioenergy/oxidative status of d...

A Biometrical study was conducted on the digestive tract of 35 foetuses of the one-humped camel collected from the Sokoto metropolitan abattoir, over a period of five months at different gestational ages. The approximate age of the foetuses was estimated from the crown vertebral rump length (CVRL) and samples were categorised into first, second and third trimester. The mean body weight of the f...

BACKGROUND The neonatal Fc receptor (FcRn) plays a crucial role in transporting IgG and associated antigens across polarized epithelial barriers in mucosal immunity. However, it was not clear that FcRn expression in aggregated lymphoid nodules area (ALNA) in abomasum, a unique and important mucosal immune structure discovered only in Bactrian camels. In the present study, 27 Alashan Bactrian ca...
