In central Australia, most 1080 (sodium monofluoroacetate) meat baits placed on soil in predator-proof cages remained toxic to dingoes, foxes and feral cats for at least 8 months regardless of whether they were protected from rain or not. Thus, untaken baits will remain a potential hazard to non-target species, particularly farm dogs, for a considerable period. However, when dingo-control programs were monitored (n = 3 stations), approximately 85% of meat baits were taken within 4 days. Dingo-control programs were undertaken on three stations by placing 1080 meat baits near water points (bores) with known dingo activity. Baiting was effective on two stations but not on the third. Where successful, dingo numbers were reduced by 50–70%. The failure on the third station was not due to the lack of bait-take as approximately 80% of these baits were taken within 4 days; it was probably caused by the presence of ephemeral water-bodies that could not be baited. However, this technique was effective in removing those dingoes that utilised the artificial water points, and hence were likely to be interacting with cattle. Such an outcome has benefits to both conservation and the pastoral industry, as problem dogs are removed without placing the long-term survival of dingoes at risk.

Abstract OBJECTIVE To describe clinical findings, treatments, and outcomes for cattle with complete traumatic exungulation. ANIMALS 10 bovines. PROCEDURES Record databases of 2 teaching hospitals were searched to identify cattle treated for traumatic exungulation between January 1993 and December 2018. Information about signalment, clinical signs and findings, treatment, and outcome was extracted from the records or obtained by telephone communication with the owner. RESULTS Records for 5 bulls, 4 heifers, and 1 cow with a median age of 2 years (range, 1 day to 10 years) and weight of 379.1 kg (range, 30 to 909.1 kg) were reviewed. Duration of clinical signs ranged from ≤ 24 hours to 3.5 days. Five of 7 animals had a lameness score > 3/5. Complete exungulation occurred in 6 medial digits (3 hind limbs and 3 forelimbs) and 5 lateral digits (1 hind limb and 4 forelimbs); 1 calf had complete exungulation of both digits of a forelimb. Treatments included bandaging (n = 9), antimicrobials (9), anti-inflammatories (8), hoof block application to the adjacent digit (7), regional anesthesia (6), cast application (4), curettage of the third phalanx (3), regional antimicrobial perfusion (1), and local application of antimicrobial-impregnated beads (1). All 7 cattle with long-term (≥ 9 months) information available returned to their intended function; 6 had no residual lameness, and 3 required regular corrective trimming of the affected digit. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested the prognosis for long-term survival and return to intended function is fair to good for cattle with complete exungulation.

Gastric cancer is one of the most common cancers and the third cause of cancer-related death worldwide. The treatment of GC patients improved due to advancements in surgery, radiotherapy and chemotherapy. However, the long-term survival rate of patients with gastric cancer remains around 20%. Thus, development of novel therapeutic approaches is of great interest, in order to reduce the need for mutilating surgeries and morbid adjuvant therapies. For many years, it was believed that the RNA was a mere intermediate molecule in the genetic information flow. However, during the past decades, with the advent of new sequencing technologies, it was revealed that non-coding RNAs play important roles in many different biological processes. The Wnt/β-catenin signaling pathway has been reported to regulate crucial events during neoplasic development, such as cell differentiation, proliferation, invasion, migration, apoptosis, and angiogenesis. In this review, we will focus on microRNAs and long non-coding RNAs that have been implicated in gastric cancer tumorigenesis via modulation of the Wnt/β-catenin signaling pathway, which provided some biomarkers to prognosis, diagnosis, and therapy.

Long-term survival is one of the main goals of family business. Nevertheless, very few firms survive to the third generation. The concept of organizational ambidexterity could add insights into the explanation of family firm (FF) survival. In the literature, organizational ambidexterity is defined as the capability to explore new knowledge, processes, and opportunities while exploiting current ones to achieve a greater competitive advantage and ensure the survival of the firm. The aim of this chapter is to review the literature that analyzes relationships between FF specificities and organizational ambidexterity to propose a framework of the antecedents of ambidexterity in this context. This could be a useful tool to better identify FF specificities that will support long-term survival through their influence on organizational ambidexterity.

The incidence of liver cancer has grown in the past decade, with 905,677 new cases and 830,180 deaths in 2020. According to the highest annual fatality ratio, liver cancer is the third-leading cause of cancer-related deaths worldwide. Surgical resection is the mainstay treatment for long-term survival. However, only 25% of patients are surgical candidates. Recent surgical concepts, techniques and multidisciplinary management were developed, including interventional radiology procedures that improve the management algorithm, expand the indications and limit dropouts from curative treatment. This review summarizes up-to-date information on interventional radiology in the management of liver tumors.

BACKGROUND: Several studies have demonstrated that the adequacy of secondary prevention is better among survivors of myocardial infarction (MI) compared with the survivors of stroke. We investigated the hypothesis that long-term survival among stroke survivors is lower than survivors of myocardial infarction. METHODS: We identified stroke and MI survivors from a nationally representative sample of 11989 US adults aged 17 to 59 years who participated in the Third National Health and Nutrition Examination Survey Mortality Follow-up Study. We compared the long-term survival between survivors of stroke and MI and those without any cardiovascular disease using Cox proportional hazards analyses. Potential confounding factors in the association between stroke and MI with death (cardiovascular and all cause) included age, sex, race/ethnicity, hypertension, hyperlipidemia, diabetes mellitus, cigarette smoking, body mass index, and alcohol use. RESULTS: A total of 485 survivors with stroke and 774 survivors with MI were included in the analysis; 74 stroke related, 128 acute MI related, and 356 ischemic heart disease related deaths and 941 all causes deaths were reported during a mean follow-up period of 8.5+/-5.3 years. After adjusting for differences in age, sex, race/ethnicity, hypertension, diabetes mellitus, cholesterol level, cigarette smoking, body mass index, and alcohol use, there was no difference among stroke survivors in likelihood of all-cause mortality (relative risk [RR], 1.1 ; 95% confidence interval [CI], 0.9 to 1.3) and cardiovascular death (RR, 0.9; 95% CI, 0.7 to 1.2) compared with persons without cardiovascular disease. CONCLUSION: Survivors of stroke face the same reduction in long-term survival as survivors of MI in the community. Therefore, proportionate efforts are required in public education and secondary prevention to improve long-term survival in these patients.

AbstractAlthough human-related disturbance is usually detrimental for biodiversity, in some instances it can simulate natural processes and benefit certain species. Changes in the disturbance regime, both natural and human-driven, can affect species that rely on it. The Apennine yellow-bellied toad Bombina variegata pachypus, an amphibian endemic to peninsular Italy, has declined throughout its range in the last 3 decades. We sought to identify the drivers of the decline in the region of Liguria, at the north-western limit of its distribution. In 2009 and 2010 we surveyed sites where the species occurred until 2005 and related the persistence of breeding activity to the characteristics of sites. Populations had disappeared from 50% of the sites between 2005 and 2009. Current breeding sites have less aquatic and bank vegetation, fewer predators and better insolation. Frequent disturbance events (desiccation and floods) were related to reduced vegetation, which in turn may decrease predator densities and increase insolation. In this region disturbance is provided by natural factors or, in the case of artificial water bodies, by regular maintenance carried out by landowners. The widespread land abandonment in Liguria can disrupt disturbance regimes, interrupting the removal of vegetation, and thus rapidly reduce the suitability of artificial sites. This was confirmed in our study, with most abandoned breeding sites occurring in formerly cultivated areas. Possible short-term conservation actions include creating new ponds, maintaining artificial water bodies and clearing vegetation. However, long-term conservation may be more problematic as the land abandonment process is unlikely to be reversed.

AbstractPacific Island land snails are highly endangered due in part to misguided biological control programs employing the alien predator Euglandina rosea. Its victims include the fabled Society Island partulid tree snail fauna, but a few members have avoided extirpation in the wild, including the distinctly white-shelled Partula hyalina. High albedo shell coloration can facilitate land snail survival in open, sunlit environments and we hypothesized that P. hyalina has a solar refuge from the predator. We developed a 2.2 × 4.8 × 2.4 mm smart solar sensor to test this hypothesis and found that extant P. hyalina populations on Tahiti are restricted to forest edge habitats, where they are routinely exposed to significantly higher solar radiation levels than those endured by the predator. Long-term survival of this species on Tahiti may require proactive conservation of its forest edge solar refugia and our study demonstrates the utility of miniaturized smart sensors in invertebrate ecology and conservation.
