Abstract
In reintroduction projects, an analysis of dispersal, exploratory movements and territorial behavior of the species concerned offers valuable information on the adaptive management of threatened species and provides a basis for the management of future reintroductions. This is the case of the Iberian lynx (Lynx pardinus) an endemic and endangered species reintroduced in Extremadura (Spain) in 2014. We analysed spatial data from 32 individuals just after their reintroduction. Our findings show exploratory movements sufficient to colonise and connect population nuclei within a radius of about 50 km of the reintroduction area. No significant differences were found in the exploratory movements capacity or in any directionality of males and females. Our results showed an effect of sex on the sizes of the territories established, as well as an inverse relationship between them and the time elapsed since release. No effects of rabbit abundance and lynx density on the size of territories are occurring during the early stages of reintroduction. On average, the territories of reintroduced individuals were less stable than those previously described in natural populations. Findings indicate that the reintroduced population has successfully been established but it takes more than 5 years to stabilize the territories in the area. Exploratory movements of reintroduced lynx can be large and in any direction, even when there is still a lot of high quality habitat available, which should be taken into account when reintroducing species, especially terrestrial carnivores.

Abstract
The restoration of Iberian lynx (Lynx pardinus) populations in Extremadura (Southwestern Spain) have been carried out since 2014. One of the measures to ensure the success of this program is to examine the effects that diseases may have on reintroduction. Since diseases may be greatly located at certain sites because of the specific ecological requirements of the pathogens and/or vectors, reintroduced individuals may present a risk of infection once released. To determine which pathogens the reintroduced individuals may encounter, we performed a molecular and sero-epidemiological survey in reintroduced and wild-born lynxes. From 2015 to 2019, 69 Iberian lynxes (40 reintroduced and 29 wild-born) were sampled and screened against 10 viral, bacterial and piroplasmid agents. In parallel, 195 sympatric carnivores from the families Canidae, Felidae, Viverridae, Herpestidae and Mustelidae were tested against current or past infections to six common canine/feline viruses. In the Iberian lynx, low contact rates of active infection were obtained for the feline leukemia provirus (FeLV: 1.5%; 1/67), feline parvovirus (FPV: 1.5%; 1/67) and Cytauxzoon sp. (6.7%; 1/15). We also confirmed the emergence of Aujeszky's disease (suid herpesvirus-1) in this population (SuHV-1: 11.8%; 2/17). Evidence of previous exposure was detected for canine distemper virus (CDV: 5.8%; 3/52), feline coronavirus (1.9%; 1/52), FPV (7.7%; 1/13) and feline calicivirus (FCV: 5.3%; 1/19). From 25 recovered lynx carcasses, we could confirm infectious etiology involvement in the death of four individuals (SuHV-1 in two individuals, coinfection of Cytauxzoon spp. and Aeromonas veronii in one lynx and a Streptococcus canis myositis in another lynx). We confirmed the circulation of CDV, FPV, FeLV, FCV and the feline immunodeficiency virus within the sympatric carnivore community. Due to the low contact rate of infectious agents in such a small, endangered population, we recommend continuing a disease surveillance program to determine the prognostic factors of survival, understand the role that disease may play during the reintroduction and anticipate disease outbreaks that may pose a risk for the entire reintroduced population.

Abstract
BACKGROUND Incisional hernia is a frequent problem after liver transplantation. It is related to immunosuppression, use of steroids, obesity, as well as the type of incision. Laparoscopic repair shows a lower rate of complications in terms of infection and recurrence, as well as reduced postoperative pain and faster recovery. METHODS We reviewed our experience with laparoscopic incisional hernia repair (LIHR) in patients after liver transplantation, using the BARD Composix mesh which is composed of two layers of polypropylene and polytetrafluoroethylene (PTFE) and fixed with metal ProTack. RESULTS Between March 2002 and April 2010, we performed 20 LIHR in 17 male and three female subjects of overall mean age of 58.3 years, and body mass Index of 31.05 kg/m(2). The mean size of the defects was 215.25 cm(2). All patients had undergone bilateral subcostal incisions with a midline extension, and seven had additional operations after the transplantation for various reasons. There were no differences in immunosuppression. Three patients had needed steroid boluses for acute graft rejection episodes. There was no conversion of therapy. The size of mesh was 18 × 23 cm in seven cases and 20 × 25 in 12 cases. The mean postoperative hospital stay was 2.1 days. Oral feeding was initiated a few hours after surgery, and routine immunosuppression was not discontinued. There were no major early complications. During follow-up, we identified one patient with a mesh infection (5%) and one with a recurrence (5%). CONCLUSION LIHR is safe and feasible even for major hernias after liver transplantation with few complications.

Abstract
The aim of this study was to ascertain postoperative changes in immunoglobulin E (IgE) in patients undergoing different types of surgery and the possible correlation with the duration and type of surgery. Evidence suggests that surgery induces a predominant activation pattern through the T-helper-2 (Th2) cell pathway, increasing interleukins (IL-4, IL-5, IL-10, IL-13), inhibiting Th1 cell activation, and promoting B and Th2 cell activation. IgE production may indicate predominant Th2 pathway activation and may be a more persistent and easily measurable postoperative marker than IL-6 for measuring surgical trauma. Altogether, 180 patients undergoing different types of surgery for nonneoplastic and nonparasitic diseases were studied. All patients received the same type of anesthesia. Before surgery and on the first (1PO) and 7th (7PO) postoperative days we determined in peripheral blood the CD3, CD4, CD8, CD16, and CD19 cell percentages; IL-1, IL-2, IL-4, IL-6, and tumor necrosis factor (TNF) levels; and the IgA, IgG, IgM, total IgE, C3, C4, and CIC levels. On 1PO, all variables decreased except IgE, IL-1, IL-2, IL-4, IL-6, CIC, and CD19. Only IgE, IL-6, and CD19 increases showed a significantly statistical (ss) difference regarding preoperative values (0.01, 0.05, 0.001, respectively). Relations between the IL-4 and IgE increases (p < 0.01) and between the IgG decrease and IgE increase (p < 0.001) were found. On 7PO, only IgE was increased (p < 0.001). The IgE increase correlated with surgical trauma intensity (p < 0.05). We concluded that IgE increases during the early postoperative period, correlating with surgical injury intensity. The increase in the IgE level may be detected 24 hours after surgery and during the first 7 postoperative days depending on the type of surgery.

Abstract
In this study, we demonstrate the production of transgenic goats by nuclear transfer of fetal somatic cells. Donor karyoplasts were obtained from a primary fetal somatic cell line derived from a 40-day transgenic female fetus produced by artificial insemination of a nontransgenic adult female with semen from a transgenic male. Live offspring were produced with two nuclear transfer procedures. In one protocol, oocytes at the arrested metaphase II stage were enucleated, electrofused with donor somatic cells, and simultaneously activated. In the second protocol, activated in vivo oocytes were enucleated at the telophase II stage, electrofused with donor somatic cells, and simultaneously activated a second time to induce genome reactivation. Three healthy identical female offspring were born. Genotypic analyses confirmed that all cloned offspring were derived from the donor cell line. Analysis of the milk of one of the transgenic cloned animals showed high-level production of human antithrombin III, similar to the parental transgenic line.

Abstract
gamma-Tubulin, a relatively new member of the tubulin gene family, is localized primarily at the centrosome throughout the mammalian cell cycle and may play a key role in nucleation of cellular microtubule assembly. A transient association of gamma-tubulin at the cytoplasmic bridge of telophase mammalian cells, the midbody, is recently documented. Using immunogold electron microscopy and serial section reconstruction analysis, we show here that the transiently associated midbody gamma-tubulin is localized at the minus ends of microtubules in the midbody structure. Using antisense RNA methods we also demonstrate that a selective depletion of transiently associated midbody gamma-tubulin causes an abortive cytokinesis due to a failure in the morphogenesis of the midbody structure.

Abstract
gamma-Tubulin, a component of spindle pole bodies in fungal cells and pericentriolar material in vertebrate cells, is thought to play a role in the nucleation of microtubule growth and to define their polarity. In contrast to the adult somatic cells, microtubules are nucleated in the absence of centrioles in mammalian oocytes and early embryos. By studying acentriolar mouse oocytes and their early development following fertilization, we show that gamma-tubulin antibody crossreacts with a 50,000 M(r) protein in unfertilized mouse oocytes and demonstrate that gamma-tubulin distribution is rearranged dramatically during fertilization. In unfertilized mouse oocytes, gamma-tubulin is concentrated in the broad spindle poles of meiotic spindle (MII) and as the distinct foci which form the centers of the cytoplasmic microtubule asters (cytasters). The integrity of these gamma-tubulin foci and their cytoplasmic location is maintained during the drug- or cold-induced depolymerization of microtubules. gamma-Tubulin is also found in the basal body of the mouse sperm. During fertilization, the gamma-tubulin is found at the cytastral centers as well as in the incorporated sperm basal body complex, and the gamma-tubulin foci coalesce at the perinuclear microtubule organizing regions of the two pronuclei at the first mitotic prophase. During mitosis, gamma-tubulin is found associated with broad bands that form the poles of the first mitotic spindle. By the late preimplantation stage, when newly generated centrioles have been reported to arise, gamma-tubulin remains localized at the centrosome of mitotic cells.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
gamma-Tubulin is a newly identified member of the tubulin family whose sequence is highly conserved from yeast to man. This minor microtubule protein is localized to the microtubule organizing centres and a mutation in the gene encoding it produces a microtubuleless mitotic arrest in the filamentous fungus Aspergillus nidulans. Here we investigate the in vivo function of gamma-tubulin in mammalian cells using a synthetic peptide to generate a polyclonal antibody that binds to a highly conserved segment of gamma-tubulin. After microinjection into cultured mammalian cells, immunofluorescence localization revealed that this antibody binds to native centrosomes at all phases of the cell cycle. In the presence of the gamma-tubulin antibody, microtubules fail to regrow into cytoplasmic arrays after depolymerization induced by nocodazole or cold. Furthermore, cells injected immediately before or during mitosis fail to assemble a functional spindle. Thus in vivo gamma-tubulin is required for microtubule nucleation throughout the mammalian cell cycle.
