Are Baltic grey seals (Halichoerus grypus grypus) exposed to phenol derivatives?

Are Baltic grey seals. AoS

Plastics and endocrine active compounds (EDCs) reaching the sea is a very current topic. Global society is beginning to notice plastics accumulating on beaches, in coastal waters and in so-called “Great Garbage Patches” in the oceans. The

Duodenal neuroendocrine tumors: what we really know about them? An Italian multicentre experience

Duodenal Neuroendocrine Tumors. AoS

Duodenal neuroendocrine neoplasms (dNENs) are heterogeneous tumors and represent up to 3% of all duodenal tumors and 2–3% of all gastrointestinal tumors. Despite clear differences, dNENs have been always treated together with either gastric neuroendocrine tumors or,

Dynamic electron microscopy: recording of ATP-induced myosin head movement in living muscle myosin filament

Muscle contraction results from relative sliding between actin and myosin filaments, caused by cyclic movement of myosin heads coupled with ATP hydrolysis. It is generally believed that individual myosin heads M), extending from myosin filaments, first bind

Skewed signaling through RAGE strength the tumor growth-promoting activities of M2 macrophages

Skewed signaling through RAGE strength. AoS

Tumors are complex tissues composed by both non-cellular components, mainly matrix proteins, and different stromal cell types, which are under an active cross talk with tumor cells. Tumor-associated macrophages (TAMs) are the major leukocyte population among the

Urbanization facilitates migration of the human health pest, Western black widow spider

Western black widow spider. AoS

By 2050, more than half of the global human population is expected to live in urban areas. As these urban areas rapidly grow, they replace some of our most pristine habitats. One effect that urbanization has is

Virtual unrolling of damaged historic scrolls from X-ray micro-tomography scans

Virtual Unrolling of Damaged Historic Scrolls. Atlas of Science

For many years there has been limited success in extracting the contents of historical parchments that are so badly damaged by fire, water, etc. that they cannot be opened or unrolled without causing further damage, meaning that

Suicide and drug overdose mortality in Australian young males as a socioeconomic malady

Suicide and drug overdose mortality in Australian young males. AoS

When mortality trends in Australian young adult (20–34 year) males are analysed over 1979–2011, some interesting features emerge. First, a decline in motor vehicle accident mortality by half between 1980 and 1998 did not translate into reduced

Future trends in high-resolution 3D visualization of individualized neurons in whole tissues using Synchrotron-based X-ray microtomography: a new world to be explored

Future trends in high-resolution 3D. AoS

The understanding of neuron cells as individualized entities has its beginning in the 19th century as a result of the work developed by Santiago Ramon y Cajal on the basis of histological techniques developed by Camillo Golgi. These

Binge eating increases compulsivity through dopamine mechanisms in the oval bed nucleus of the stria terminalis

Binge eating increases compulsivity through dopamine mechanisms. AoS

Binge eating is a common feature of disordered eating and the defining characteristic of binge eating disorder (BED), the most prevalent of all eating disorders. Binge eating, with or without a psychiatric diagnosis, is a likely contributor

Alpha-amylases from stemborer pest caterpillars inform the Cotesia parasitoids on their suitability

Alpha-amylases from stemborer. AoS

Biological control, using parasitoids in particular, has received increased attention because this control method is cost effective and offers a management strategy that safeguards human health and the environment. Insect parasitoids are, in many cases, a significant

Multimodal sensory processing in Caenorhabditis elegans

Multimodal sensory processing in Caenorhabditis elegans. AoS

During their lifetime, organisms need to adapt to the environment by evaluating and responding to numerous and diverse external cues. The nervous system senses these cues and integrates them, a process called multisensory integration. Research on sensory

Latin America Is The New IT Outsourcing Hotspot


Outsourcing IT projects to Latin America can offer your U.S. company cost savings, while still providing access to a highly educated talent pool with high English proficiency. Additionally, you’ll have the benefits of a nearby time zone

Bessel-Bessel laser bullets: not that kind of bullet!

Bessel-Bessel laser bullets: not that kind of bullet. AoS

A light bullet produced by a powerful laser system, and a metallic bullet fired from a real gun, have at least one sure thing in common: they both may cause real damage to objects and people. But

Developmental origins of aging trajectory

Traditionally, gerontological research is focused on later stages of life cycle. Accumulating evidence, however, suggests that the rate of aging-associated functional decline (senescence) as well as the risk for chronic pathological conditions can originate early in life.

Predictive safety assessment of engineered nanomaterials

With the rapid development and numerous applications of engineered nanomaterials (ENMs) in science and technology, their impact on environmental health and safety should be considered carefully. This requires an effective platform to investigate the potential adverse effects

Due to the obesity epidemic, the incidence and prevalence of type 2 diabetes mellitus continues to rise globally. Type 2 diabetes is characterised by a relative insulin deficiency and an impaired insulin sensitivity in certain specific target organs. Insulin sensitivity can

Should we think that neem gum polysaccharide and their semi-synthetic derivatives can be utilized as carrier for nanoformulation

Schematic diagram to show the method of nanoparticle formulation. AoS

One of the major concerns related to the newly synthesized drug is poor water solubility, which seems to be a major concern for the pharmaceutical manufacturer and also a rate limiting step in the bioavailability. In this
