How we can curb deaths from heroin use

Evidence from many countries shows an alarmingly high death rate amongst former prisoners with histories of heroin addiction in the two weeks following their prison release. A heroin overdose is the most common cause of death in

What can we achieve for average spin Hamiltonians in solid-state nuclear magnetic resonance spectroscopy?

nuclear magnetic resonance spectroscopy. AoS

Multiple-pulse sequences (MPS) have been widely applied in nuclear magnetic spectroscopy to manipulate spin Hamiltonians (such as isolating or enhancing certain interactions while removing the effects of all other interactions), to measure relaxation times, and to enhance

Nailfold microangiopathy in dermatomyositis and systemic sclerosis: what is different in long term follow-up?

Nailfold videocapillaroscopic pictures. AoS

Dermatomyositis (DM) is a chronic inflammatory disorder involving mainly the skin and muscles. Systemic Sclerosis (SSc) is an autoimmune rheumatic disease of unknown etiology characterized by vascular alterations and progressive tissue fibrosis of multiple organs. Peripheral microangiopathy

Effects of nitric oxide donation and nuclear factor-kappa B inhibition on schistosomiasis mansoni

Effects of nitric oxide donation and nuclear factor-kappa B

Schistosoma chronically infects millions of people worldwide, and is considered an important cause of liver fibrosis; a reversible wound healing that reflects a balance between liver repair and scar formation, and is mainly maintained by chronic activation

Driving time delays treatment initiation for tuberculosis in Uganda

Driving time delays treatment initiation for tuberculosis. Atlas of Science

We investigated the association between distance to health care facilities and delay in treatment initiation for patients with tuberculosis in Kampala, Uganda. We used a theoretical construct known as appraisal delay, which is the approximate time in

Understanding the behavior of fly larvae from neural activities in their isolated central nervous system

Understanding the behavior of fly larvae. AoS

You may have heard about “The brain in a vat”, the philosophical scenario which talks about simulated reality and conceptions. It may sound bizarre and unrealistic. However, larval fruit fly neuroscientists literally perform the experiment to understand

Does intestinal inflammation impact the lung response to bacterial endotoxin?

Lung inflammation leading to airway hyperresponsiveness causes illnesses for more than ten percent of the population in USA. Recent research had indicated that patients with inflammatory bowel disease have higher incidence of airway hyperresponsiveness compared to the

Understanding painful sex

Understanding Painful Sex. AoS

Feeling severe pain while trying to have intercourse is one of the worst experiences that can occur in a sexual relationship.  The most frequent cause of such pain is felt immediately upon penetration, i.e. at the entrance

Topical treatments for actinic keratoses: the bill, please!

Topical treatments for actinic keratoses. AoS

Actinic Keratosis (AK) is a cutaneous pre-malignant lesion presenting with a scaly and reddish patch or plaque. It is caused by chronic ultraviolet light exposure, therefore, it affects most often sun-exposed areas of the body and is

Tracking the building material sources of ancient Romans in north-eastern Italy

Tracking the building material sources of ancient Romans in north-eastern Italy. Atlas of Science

One of the many facets of cultural heritage studies is the identification of the possible sources of raw materials in ancient times. Samples from Roman buildings dating back to I century B.C. – II century A.D. and

Building an artificial kidney from human stem cells

Building an Artificial Kidney from Human Stem Cells. AoS

Many diseases and drugs affect kidney function by damaging the glomeruli — the major site of blood filtration and a target for many diseases. An in vitro model of the human glomerulus could facilitate therapeutic discovery and

Hospital, infections and the Matthew effect

Hospital, Infections and the Matthew Effect. AoS

Berlin’s Charité hospital, the city’s largest, has an illustrious past. Founded some 300 years ago, it became part of what is presently Humboldt University in 1810, and between1901-1908 three Nobel laureates in Physiology or Medicine were on

Keeping an “eye” on the structure and role of visual cycle proteins

The structure and role of visual cycle proteins. AoS

Opsins are ocular proteins in photoreceptors that transform light energy to initiate signals for vision. Each opsin contains an 11-cis-retinal chromophore which is converted into all-trans-retinal when activated by a photon. The all-trans-retinal must be recycled back

First report describing the spatial-temporal circulation and the genetic diversity of Parapoxvirus species in Mexico

Parapoxvirus species in Mexico. AoS

The Mexican-USA Commission for the Prevention and Diagnosis of Foot and Mouth Disease laboratory (CPA) plays a critical role for the diagnosis and surveillance of animal diseases in Mexico. In this level 3 biosecurity facility foreign viral

Chronic kidney disease . Atlas of Science

Chronic kidney disease (CKD) is a huge global health burden. If not treated promptly, CKD can progress to end-stage renal disease, meaning that kidney function is at below 10% of normal capacity. Under physiological conditions the kidneys

Superradient and subradient emission of molecules coupled via plasmons

A physical dipole consists of two equal and opposite point charges. Atoms and molecules can be viewed like oscillating dipoles, picturing each atom as a tiny antenna emitting electromagnetic waves. The excited atomic states are relaxing to

Taking medicines the right way: what do people with Parkinson’s do?

Many people with Parkinson’s have problems swallowing, but they need to take many medicines to lead an independent life. It is more important for people with Parkinson’s to take their medicines on time compared with other patient

Consciousness hidden in the brain fissure

Consciousness, informally stated as the subjective feeling of being, comprises of two basic components—arousal (wakefulness) and awareness (awareness of environment and self). Although the posteromedial cortex (PMC), an area hidden in the posterior interhemispheric fissure, has been

Ovarian torsion or something else

Ovarian Torsion or Something Else. AoS

Ovarian torsion, also termed as adnexal torsion, is the total or partial twisting of the ovary and almost always involves part of the fallopian tube. The incidence of adnexal tumors increases with age and one of the

Oxygen starvation promotes pro-tumorigenic cytokine expression

Oxygen Starvation Promotes Pro-Tumorigenic Cytokine Expression. AoS

Identification of the factors that trigger tumor formation and metastasis is a problem that has persisted in cancer research since its inception. To date, studies have focused on chemical signaling compounds that are part of the secretome
