Blood vessels regulate fetal brain growth

Millions of neurons are generated during fetal development from progenitor cells that reside inside the embryonic brain More »

Species are always important

This review is based on the premise that all species are important to life on earth even if the exact role or value of a species has not been formally documented More »

Virus chainmail: protective and porous metal-organic framework grown on a virus

Biomineralization describes a process of programmable accumulation, concentration, and construction of inorganic ions regulated by organisms to form both amorphous More »

Risky attraction to the familiar smell of disease

Many animals remember smells, sights, and sounds (‘cues’) they encounter as juveniles, like the smell of nearby individuals, or their environment. More »

 

Infected stent graft behind the knee

Popliteal artery aneurysms are the commonest peripheral artery aneurysm and affect 1% of men aged 65 to 80 years. The popliteal artery in the main artery behind the knee and an aneurysm is where the blood vessels

Diamond growth using microwave-activated methane/hydrogen plasmas

Diamond is renowned for its many superlative material properties. It defines the top of the Mohs hardness scale, has the highest bulk thermal conductivity at room temperature, and has a very low coefficient of thermal expansion. The

Reducing single-use plastic shopping bags

Thin-film, single-use shopping bags are ubiquitous throughout the world. Since the 1980s, consumers have been habitualized into expecting free plastic shopping bags at businesses. In the US, the estimated annual per capita consumption of single-use plastic shopping

Eccentric metallo-dielectric core-shell nanoparticles for light guiding and switching

High Refractive Index Dielectric (HRID) nanoparticles (NPs) have been proposed as an alternative to metallic ones due to their low absorption and magnetodielectric response in the VIS and NIR ranges. Important scattering directionality (SD) effects can be

p53: key conductor of all anti-acne therapies

Acne vulgaris is the most common inflammatory skin disease of developed countries affecting more than 80% of adolescents. In contrast, acne vulgaris is not epidemic or completely absent in populations living under Paleolithic conditions. During the last

Does statins increase risk of diabetes?

Statins are drugs that inhibit the enzyme 3-Hydroxy-3-methylglutaryl-coenzymeA (HMG-CoA) which is critical in the production of cholesterol molecules. Thus is commonly used in the treatment of abnormally elevated cholesterol which is known to contribute to cardiovascular disease

3MST produces redox regulators Cys-SSH and GSSH as well as signaling molecules H2S and H2Sn

3-Mercaptopyruvate sulfurtransferase (3MST) together with cysteine aminotransferase (CAT) produces hydrogen sulfide (H2S), a well-known toxic gas, from L-cysteine. 3MST also produces H2S from D-cysteine in concert with D-amino acid oxidase (DAO). Cystathionine β–synthase (CBS) and cystathionine γ–lyase

Heavy metal resistant–plant growth promoting bacteria as an alternative strategy for decreasing accumulation of metals in plant tissues

In the present era, pollution of water, soil and air with heavy metals is increasing rapidly. Industrialization and technological advancement have caused serious damage to the ecosystem by releasing large quantities of heavy metals (i.e., cadmium, chromium,

Proline analogues present anti-Trypanosoma cruzi activity through inhibition of proline transporter

Trypanosoma cruzi is the protozoan parasite that causes Chagas disease, an illness that affects approximately 7 million people in Latin America. Nowadays there are only two drugs approved for Chagas treatment, benznidazole and nifurtimox. Both drugs were

Synthesis of industrial relevant ZSM-5 supported nano-sized metallic cobalt catalyst

Most chemical reaction of industrial relevance are catalysed by different metals in their metallic state. However, after catalyst synthesis which involves calcination to adequately anchor those active metals unto the catalyst supports, the metals were oxidized, thus

Activation by inhibition

Phosphorylation of proteins is one of the most important mechanisms through which protein function is quickly and reversibly regulated. Prototypically, an extracellular ligand binds to its cognate receptor(s) on the surface of a target cell, leading to

Dyspepsia – common; many causes, few cures

Dyspepsia (which literally means “bad digestion”) or as, it is commonly referred to in the English language, indigestion, is an umbrella term used to encompass a number of symptoms thought to originate from the upper gastrointestinal tract.

Discriminating live and dead sperm in ecotoxicology

Reproductive toxicity is an emerging topic in Ecotoxicology aimed to evaluate adverse impact of environmental stressors to reproductive systems and processes. Sexual reproduction is the complex process that marks the creation of a new individual of the

Why deaf identity matters

Deaf people have long protested against a disability view of deafness as an impairment that should be cured, and argued for Deaf culture as a unique culture and for sign languages as unique languages. Parallel to the

A turn of the head can cause a stroke

The major arteries of the neck cumulatively constitute the cervical arteries. They are highly important because they are the blood supply for the brain. There are four major cervical arteries: the right and left carotid arteries and

HDAC inhibitors: a new promise for anti-aging

Epigenetic modifications provide a mechanism of heritable but reversible changes in gene function that occur without the change in the primary DNA sequence due to alterations in chromatin structure. The global changes in chromatin structure and certain
