Protein polymorphisms of Goats in Tunisian Oases
M. Nafti,Z. Khaldi,B.Haddad
Biomirror , 2013,
Abstract: The main objective of this study was to assess the genetic variation between the two goat populations in the region of Tozeur, Arbi and Serti, by means of blood protein polymorphism. A total of 97 animals from two indigenous goat types were investigated. The determination of red cell lysates and plasma proteins were carried out by starch gel electrophoresis. Two alleles were detected at all loci investigated; haemoglobin, transferrin, carbonic anhydrase, albumin and X-protein for each populations. Esterase was typed as described by Tucker et al. (1967)19, where two phenotypic variants occurred, namely EsA-positive and EsA-negative. In most cases, the observed genotype frequencies were not significantly different from that expected under Hardy-Weinberg equilibrium except for carbonic anhydrase. The mean number of alleles per locus was between 1.61 and 1.67 for the Arbi and the Serti populations, respectively. The expected mean heterozygosities were between 0.29 and 0.38 while the observed mean heterozygosities were from 0.34 to 0.38. Most of the diversity obtained was located within populations. Cluster analysis based on Nei (1972)9 standard genetic distance and Nei (1978)11 standard genetic distance and Unweighted Pair Group Method with Arithmetic Mean dendrogram revealed low level of genetic distance between populations and relatively higher genetic distance within populations.

Reproductive activity and vocalizations of Leptodactylus labyrinthicus (Anura: Leptodactylidae) in southeastern Brazil
Zina, Juliana;Haddad, Célio F. B.;

Abstract: vocalizations and reproductive activity of two leptodactylus labyrinthicus populations were studied from jun/2001 to feb/2003 in the state of s?o paulo, brazil. observations began at dusk and ended around 2300 h. occasionally individuals were monitored throughout the night. data on reproductive period, calling sites, adult snout-vent length (svl), oviposition sites, and oviposition period was collected. leptodactylus labyrinthicus had an extended breeding period associated mainly with rainfall. males called from the edge of temporary or permanent ponds, began vocalization activity at dusk, and finished around 2300 or 2400h. during the peak of the vocalization period (dec- jan), calling activity could extend up to 0400 or 0500h. three types of vocalizations associated with reproduction were recorded: advertisement call, territorial call, and courtship call. the advertisement call was the most common vocalization. males and females showed no sexual dimorphism in svl. however, the males of one population were significantly larger than those of the other population studied. this fact could be explained by frog-hunting in one of the areas, which could wipe out the larger males of the population. foam nests were recorded mainly in oct-nov 2001/2002 in depressions at the edge of temporary ponds, always protected by vegetation. a mean of 6.5% of the eggs present in the foam were fertilized and the other 93.5% possibly are used as a food source by the tadpoles. mean diameter of the foam nest was 25.4 cm and mean height was 11.4 cm.

Brazilian Archives of Biology and Technology , 1999, DOI: 10.1590/S1516-89131999000200005
Abstract: leaf senescence induced by sodium chloride was studied in hydrocotyle bonariensis lam. and foeniculum vulgare l. both species belong to umbelliferae family, however only h. bonariensis grows spontaneously in sandy soils of coastal regions (saline soils). leaves of plants receiving nutrient solutions containing different concentrations of nacl were evaluated for fresh and dry weights and chlorophyll content. the denaturating electrophoretic profiles of leaf proteins were also studied. sodium chloride changed the protein profile of f. vulgare and hastened the leaf senescence of both the species. however, plants of h. bonariensis receiving 599 mm nacl lasted longer than f. vulgare. therefore, the occurrence of h. bonariensis in saline soils might be related with mechanisms of salinity tolerance.

Diagnostic approach to patients with acute idiopathic and recurrent pancreatitis, what should be done?
Mohammad Al-Haddad and Michael B Wallace
World Journal of Gastroenterology , 2008,
Abstract: Acute recurrent pancreatitis (ARP) is a common clinical condition that may be difficult to diagnose. Endoscopic ultrasound (EUS) is proposed to be a safe first line test of choice in the majority of patients. When interventions are needed to remove biliary stones, evaluate sphincter of Oddi or pancreas divisum, endoscopic retrograde cholangiopancreatography (ERCP) is recommended. Magnetic resonance cholangiopancreatography (MRCP) can be a suitable alternative from a diagnostic standpoint although may not be widely available. Finally, genetic testing is increasingly used to detect certain mutations that are associated with this diagnosis.

Radar shadow detection in SAR images using DEM and projections
V. B. S. Prasath,O. Haddad
Computer Science , 2013, DOI: 10.1117/1.JRS.8.083628
Abstract: Synthetic aperture radar (SAR) images are widely used in target recognition tasks nowadays. In this letter, we propose an automatic approach for radar shadow detection and extraction from SAR images utilizing geometric projections along with the digital elevation model (DEM) which corresponds to the given geo-referenced SAR image. First, the DEM is rotated into the radar geometry so that each row would match that of a radar line of sight. Next, we extract the shadow regions by processing row by row until the image is covered fully. We test the proposed shadow detection approach on different DEMs and a simulated 1D signals and 2D hills and volleys modeled by various variance based Gaussian functions. Experimental results indicate the proposed algorithm produces good results in detecting shadows in SAR images with high resolution.

Research Journal of Dairy Sciences , 2012,
Abstract: The objective of this study was to evaluate animal welfare in a large dairy herd in the north of Tunisia. Housing conditions, reproductive and productive performances and health care were studied to assess comfort of Holstein cows in the Complexe Agro-Industriel Ghzala Mateur (CAIGM). Data were collected on the housing system, reproduction (from 2000-2006), milk production (33,829 test-day records from 2004-2006) and culling and death incidence. Barns were found not to meet the standards for cows comfort. There was a degradation of housing conditions because sheds were implemented in low ground, barns concrete coating was deteriorating, litter was in bad shape and there was a persistent draught. Reproductive and productive performances and health indicators reflected also discomfort of cows. In fact, milk production level was low. Mean milk yield was 5150 kg (standard deviation = 1694 kg) recorded over a 320.3 days (standard deviation = 82 days) lactation period. Mean somatic cell count was 634.72 103 C mL-1 (standard deviation = 1598 C mL-1), indicating probably a high mastitis infection rate. Results on reproduction showed limited fecundity and fertility of cows. Mean calving interval and insemination per conception were 445 days (standard deviation = 97 days) and 2.43 (1.6), respectively. Infertility, dystocia, post-partum calving, leg and metabolic disorders and lung diseases were the main causes of culling and death of cows. Animal welfare may be improved by continuous maintenance of barns and the improvement of housing conditions in the CAIGM in order to allow cows to perform up to their potential.
