Attention-deficit hyperactivity disorder (ADHD) is often comorbid with anxiety disorders and previous studies observed that anxiety could have an impact on the clinical course of ADHD and comorbid disruptive behavioral disorders (conduct disorders and oppositional-defiant disorders). Anxiety sensitivity (AS) is a different concept from anxiety per se and it is ...

The greenbug, Schizaphis graminum (Rondani), is a major pest of cereals in some parts of the world and is of particular concern because it can be resistant to some insecticides and overcome the resistance of crops. In the UK, it has never been found on crops, but two rather little-known ...

BACKGROUND: Although testing and treatment for Staphylococcus aureus colonization before total joint arthroplasty (TJA) are well described and understood, the durability of decolonization has not been studied extensively.

A series of 1,2-bis(arylimino)acenaphthylidenes () and their corresponding 4,4'-methylenebis(1-(2,6-diisopropylphenylimino)-2-(arylimino)acenaphthylene) derivatives () were synthesized and used to form mono-nuclear nickel bromides NiBr2 (n = 1-5, ) and bi-nuclear nickel halides Ni2X4 (n = 6-10: X = Br, ; n = 4, X = Cl, ). All the organic compounds were fully ...

Rabies virus (RV) and canine distemper virus (CDV) can cause significant mortality in wild carnivore populations, and RV threatens human lives. We investigated serological patterns of exposure to CDV and RV in domestic dogs (Canis familiaris), African wild dogs (Lycaon pictus), black-backed jackals (Canis mesomelas), spotted hyenas (Crocuta crocuta), striped ...

The theory of computation and category theory both employ arrow-based notations that suggest that the basic metaphor "state changes are like motions" plays a fundamental role in all mathematical reasoning involving formal manipulations. If this is correct, structure-mapping inferences implemented by the pre-motor action planning system can be expected to ...

Resistant hypertension is highly prevalent, and is the form of arterial hypertension that is most difficult to treat. Many patients diagnosed with this disease do not have resistant hypertension, but rather have mismanaged primary hypertension. In many cases blood pressure can be controlled by directly addressing underlying causes such as ...

Bifidobacterium genus members have been associated with a lean status, whereas different ...

Cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) has always been considered to be a middle-age-onset disease. Diagnosis is confirmed by genetic testing and the finding of the Notch3 mutation or by skin biopsy. Imaging plays a pivotal and crucial role in confirming this diagnosis by identifying white matter ...
