Extracellular polymeric substances (EPS) and solids concentrations in samples from the Interchange Bioreactor (IBR) andreturn activated sludge (RAS) from Cannibal® plants having low and high sludge yields were analyzed to understand the mechanisms behind low sludge production. Low sludge yields correlated to more EPS degradation, higher concentrations of iron, and reducing conditions in the IBR. In the low-yield plants, iron was reduced when the RAS passed through the anaerobic and reducing conditions of the IBR, and this led to more EPS solubilization and degradation...

The epidermal growth factor receptor (EGFR) and its associated pathway is a critical key regulator of CRC development and progression. The monoclonal antibodies (MoAbs) cetuximab and panitumumab, directed against EGFR, represent a major step forward in the treatment of metastatic Colorectal cancer (mCRC), in terms of progression-free survival and overall survival in several clinical trials. However, the activity of anti-EGFR moAbs appears to be limited to a subset of patients with mCRC. Studies have highlighted that acquired-resistance to anti-EGFR MoAbs biochemically converge into Ras/Raf/Mek/Erk and PI3K/Akt/mTOR pathways...

An analysis of the crop contents of the poultry shaft louse, Menopon gallina indicates that 67 % of adult males and 72 % of the adult females examined carried red content compatible to host blood, along with feather barbules. The percentage of nymphal instars carrying red content in the crop was quite low. On the basis of crop contents the louse does not seem to harbor any triturating agent and is also not involved in cannibalism or predation. SEM studies on the ventral side of head do not indicate the presence of any pointed structure which can be used to pierce the skin...

This study investigated effects of species interactions like competition and (intraguild) predation on the sensitivity of aquatic organisms to the insecticide chlorpyrifos. In the first experiment, combined effects of chlorpyrifos and different levels of intra- and inter-specific interaction were assessed on Gammarus pulex survival using Asellus aquaticus as an interacting species. Intra- and inter-specific interactions increased the time to extinction of G. pulex up to a factor of two, most likely due to the cannibalistic nature of G...

The structured population LPA model is studied. The model describes flour beetle (Tribolium) population dynamics of four stage populations: eggs, larvae, pupae and adults with cannibalism between these stages. We concentrate on the case of non-zero cannibalistic rates of adults on eggs and adults on pupae and no cannibalism of larvae on eggs, but the results can be numerically continued to non-zero cannibalism of larvae on eggs. In this article two-parameter bifurcations in LPA model are analysed. Various stable and unstable invariant sets are found, different types of hysteresis are presented and abrupt changes in dynamics are simulated to explain the complicated way the system behaves near two-parameter bifurcation manifolds...

A small radiolucent area in the mandible was discovered in a 58-year-old woman with no oral complaints. The patient's history included only hypertension. The lesion was considered as an inflammatory cyst and was enucleated. Three months later, a CT revealed the presence of a cyst-like lesion in the mandible with thin expanded buccal cortical plate, localized erosion, and a polylobate appearance on the lingual aspect of the cortical plate. The histological diagnosis of the lesion was central giant-cell granuloma (CGCG)...

AIM: Cellular cannibalism is defined as the ability of a cell to engulf another cell of its own type or any other. It has been recognized in various malignancies and is linked well with the aggressiveness, degree of anaplasia, invasiveness and metastatic potential. Literature search fetched up very few studies related to the presence and significance of cannibalism with respect to Oral squamous cell carcinoma [OSCC]. The present study was aimed to detect tumor cell cannibalism in OSCC and to validate its role as a prognosticator of OSCC in relation to metastasis and degree of differentiation...

Systematic infanticide of unrelated young has been reported in several animal taxa. Particular attention has been given to carnivores and primates, where infanticide is a sexually selected strategy of males to gain increased access to female mating partners. Cannibals must ensure avoiding their own offspring and targeting only unrelated young. Therefore, decision rules are needed to mediate parental and cannibalistic behaviour. Here we show experimentally that male poison frogs adjust their parental responses - care or infanticide - towards unrelated clutches according to their territorial status...

Within the colonial setting of the Belgian Congo, the process of cutting the body, whether living or dead, lent itself to conflation with cannibalism and other fantastic consumption stories by both Congolese and Belgian observers. In part this was due to the instability of the meaning of the human body and the human corpse in the colonial setting. This essay maps out different views of the cadaver and personhood through medical technologies of opening the body in the Belgian Congo. The attempt to impose a specific reading of the human body on the Congolese populations through anatomy and related Western medical disciplines was unsuccessful...

Hominin dietary specialization is crucial to understanding the evolutionary changes of craniofacial biomechanics and the interaction of food processing methods' effects on teeth. However, the diet-related dental wear processes of the earliest European hominins remain unknown because most of the academic attention has focused on Neandertals. Non-occlusal dental microwear provides direct evidence of the effect of chewed food particles on tooth enamel surfaces and reflects dietary signals over time. Here, we report for the first time the direct effect of dietary abrasiveness as evidenced by the buccal microwear patterns on the teeth of the Sima del Elefante-TE9 and Gran Dolina-TD6 Atapuerca hominins (1...

Placentophagia or the consumption of the afterbirth is reported in many primate species, whereas cannibalism is a relatively rare event. Based on our field observations over the course of 3 years, we present evidence of placentophagia and mother-infant cannibalism in a free-ranging population of the Taihangshan macaque, Macaca mulatta tcheliensis, in the Mt. Taihangshan area, Jiyuan, Henan, China. We documented 1 case in which a mother consumed the afterbirth of her infant. In a second instance, we observed a fresh placenta discarded on the ground by an unknown individual...

Tracy E Douglas, David C Queller, Joan E Strassmann
Unequal investment by different sexes in their progeny is common and includes differential investment in the zygote and differential care of the young. The social amoeba Dictyostelium discoideum has a sexual stage in which isogamous cells of any two of the three mating types fuse to form a zygote which then attracts hundreds of other cells to the macrocyst. The latter cells are cannibalized and so make no genetic contribution to reproduction. Previous literature suggests that this sacrifice may be induced in cells of one mating type by cells of another, resulting in a higher than expected production of macrocysts when the inducing type is rare and a giving a reproductive advantage to this social cheat...

Most social networking services support multiple types of relationships between users, such as getting connected, sending messages, and consuming feed updates. These users and relationships can be naturally represented as a dynamic multi-view network, which is a set of weighted graphs with shared common nodes but having their own respective edges. Different network views, representing structural relationship and interaction types, could have very distinctive properties individually and these properties may change due to interplay across views...

Relapse in cancer patients following an apparent cure and a prolonged latency period, known as tumor dormancy, remains an unrelenting clinical crisis. Here, I expand on our recent findings that potentially link cancer cell cannibalism of bone marrow-derived mesenchymal stem/stromal cells (BM-MSCs) to the senescence-associated secretory phenotype (SASP) and tumor dormancy.

Cannibalism has been commonly observed in fish from northern and alpine regions and less frequently reported for subtropical and tropical fish in more diverse communities. Assuming all else being equal, cannibalism should be more common in communities with lower species richness because the probability of encountering conspecific versus heterospecific prey would be higher. A global dataset was compiled to determine if cannibalism occurrence is associated with species richness and latitude. Cannibalism occurrence, local species richness and latitude were recorded for 4,100 populations of 2,314 teleost fish species...

Nonconsumptive effects of predators on prey are well known, but similar effects among competing predators are not. Aphidophagous insect larvae are notorious for cannibalism and intraguild predation, as they compete for aggregated but ephemeral prey. We tested for indirect effects of competitors on the development of Coleomegilla maculata DeGeer and Hippodamia convergens Guerin-Meneville (Coleoptera: Coccinellidae), and a green lacewing, Chrysoperla carnea Stephens (Neuroptera: Chrysopidae), with all larvae reared on eggs of Ephestia kuehniella Zeller (Lepidoptera: Pyralidae)...

Sexual cannibalism occurs in several arthropod taxa, but its evolutionary significance has long been debated. A new study shows how females that eat their mates benefit in ways that go well beyond caloric nutrition.
