INTRODUCTION: The ANT Foundation is one of the main non-profit organizations providing palliative care in Italy. For more than 30 years, it has developed a comprehensive home palliative care program for cancer patients predominately active in the Bologna province. One of its main achievements has allowed for the majority of patients to be assisted at home during the last weeks of their lives until time of death. The purpose of the present study is to evaluate the possible impact of the ANT program on health data relating to the location of where cancer patients die within the Local Health Care system area (AUSL) of Bologna, compared to what happens in the other AUSLs of the Emilia-Romagna Region (ERR) where it is not present...

On-farm euthanasia is a critical welfare issue in the poultry industry and can be particularly difficult to perform on mature turkeys due to their size. We evaluated the efficacy of two commercially available non-penetrating captive bolt devices, the Zephyr-EXL and the Turkey Euthanasia Device (TED), on 253 turkeys at three stages of production: 4-5, 10, and 15-20 weeks of age. Effectiveness of each device was measured using both ante- and post-mortem measures. Application of the Zephyr-EXL resulted in a greater success rate (immediate abolishment of brainstem reflexes) compared to the TED (97...

The aboveground ant nests are admitted as hot spots for CO2 emissions which increase heterogeneity of soil carbon (C) flux in forest ecosystems. However, little is known about effects of underground-nesting ant species on C emissions in tropical forests, where the ants have high diversity and abundance. In this study, we chose three underground-nesting ant species with different feeding-behaviors (Pheidole capellini - predominantly honeydew harvester, Odontoponera transversa - predominantly predator, and Pheidologeton affinis - scavenger) to explore their impacts on soil CO2 emission in Xishuangbanna tropical forest, China...

The voltage-dependent K+ (Kv) channel Kv2.1 is a major delayed rectifier in many secretory cells, including pancreatic β-cells. In addition, Kv2.1 has a direct role in exocytosis at an undefined step, involving SNARE proteins and independent of its ion-conducting pore function. Here, we elucidated the precise step in exocytosis. We previously reported that syntaxin 3 (Syn-3) is the key syntaxin that mediates exocytosis of newcomer secretory granules that spend minimal residence time on the plasma membrane before fusion...

One of the basic challenges in developing structural methods for systematic audition on the quality of biomedical ontologies is the computational cost usually involved in exhaustive sub-graph analysis. We introduce ANT-LCA, a new algorithm for computing all non-trivial lowest common ancestors (LCA) of each pair of concepts in the hierarchical graph induced by an ontology. The computation of LCA is a fundamental step for non-lattice approach for ontology quality assurance. Distinct from existing approaches, ANT-LCA only computes LCAs for non-trivial pairs, those having at least one common ancestor...

To compare trace mineral (TM) repletion in feedlot steers after depletion by S and Mo, 72 Red Angus steers blocked by BW (253 ± 14 kg) were assigned (6 steers per pen, fed via GrowSafe bunks) to corn silage depletion diets (DEP) supplemented with NRC (1996) recommended concentrations of Cu, Mn, Se, and Zn (CON) or supplemented with 0.3% S (CaSO4), 2 mg of Mo/kg DM, and no added Cu, Mn, Zn, or Se (ANT). Three 62 d TM repletion strategies (REP) were applied within DEP diets on d 89: 1) Multimin90 injection (contains Cu, Mn, Se, Zn) and 100% of recommended Cu, Mn, Zn, and Se from inorganic sources (ITM), 2) saline injection and 150% of recommended TM from inorganic sources (ING), or 3) saline injection and 150% of recommended TM provided as 25% organic and 75% inorganic sources (BLEND)...

The elephant is in the room-a metaphorical idiom for an obvious problem or risk that nobody wants to discuss. This abstract is not intended to be a summary, to reveal major findings, or unveil conclusions. On the contrary, it is aimed to provoke curiosity as to the question of corporate survival. Is there any recipe to be followed for companies to achieve this? The answer comes neither from the modest and traditional study rooms of philosophers nor the recent fact-based studies from the offices (and well-paid opinions) of business consultants...

OBJECTIVES: San Juan ante Portam Latinam is one of a small number of European Neolithic sites meeting many of the archaeological criteria expected for a mass grave, and furthermore presents evidence for violent conflict. This study aims to differentiate between what is potentially a single episode of deposition, versus deposition over some centuries, or, alternatively, that resulting from a combination of catastrophic and attritional mortality. The criteria developed are intended to have wider applicability to other such proposed events...

In socials insects, exploration is fundamental for the discovery of food resources and determines decision-making. We investigated how the interplay between the physical characteristics of the paths leading to food sources and the way it impacts the behaviour of individual ants affects their collective decisions. Colonies of different sizes of Lasius niger had access to two equal food sources through two paths of equal length but of different geometries: one was straight between the nest and the food source, and the other involved an abrupt change of direction at the midway point (135°)...

BACKGROUND: Ticks and tick-borne pathogens are a global problem for the health of humans and their livestock. Wood ants are important ecosystem engineers in forests worldwide. Although both taxa are well studied, little is known about their interactions under natural conditions. The purpose of the present field study was to test whether European red wood ants (Formica polyctena) influence the abundance of Ixodes tick populations in temperate forests. METHODS: Data collection took place in 130 sampling plots located at 26 ant nest sites paired with 26 control sites in northwestern Switzerland...

Leptomeningeal carcinomatosis is a devastating condition with very poor prognosis. With advances in cancer treatment leading to improved survival in solid tumours, the incidence of ante-mortem diagnosis of leptomeningeal carcinomatosis is likely to rise. Without a high index of suspicion and appropriate imaging the diagnosis can be missed. We report two cases of leptomeningeal carcinomatosis secondary to metastatic breast disease with varied clinical presentation where the diagnosis was initially missed.

This study clarifies the location, size and age at the onset of metamorphosis in Japanese eels Anguilla japonica through oceanic surveys, rearing experiments and analyses of the morphology and otoliths of leptocephali and glass eels. Twenty-eight metamorphosing leptocephali were collected in the mesoscale eddy region to the east of Taiwan during research expeditions in 2004. Rearing experiments showed that the total length (LT ) of leptocephali decreased by an average of 12·5% during metamorphosis and 13·9% during the 2-12 h after death...

Our first aim was to compare the anaerobic threshold (AnT) determined by the incremental protocol with the reverse lactate threshold test (RLT), investigating the previous cycling experience effect. Secondarily, an alternative RLT application based on heart rate was proposed. Two groups (12 per group-according to cycling experience) were evaluated on cycle ergometer. The incremental protocol started at 25 W with increments of 25 W at each 3 minutes, and the AnT was calculated by bissegmentation, onset of blood lactate concentration and maximal deviation methods...

Anthropogenic disturbance and climate change are major threats to biodiversity. The Brazilian Caatinga is the world's largest and most diverse type of seasonally dry tropical forest. It is also one of the most threatened, but remains poorly studied. Here, we analyzed the individual and combined effects of anthropogenic disturbance (three types: livestock grazing, wood extraction, and miscellaneous use of forest resources) and increasing aridity on taxonomic, phylogenetic and functional ant diversity in the Caatinga...
