Histamine is a mediator of many physiological processes. It plays an important role in modulating allergy reactions and immune system responses. H1 receptor is a therapeutic target for drugs applied in allergic diseases such as allergic rhinoconjunctivitis, urticarial, or atopic dermatitis. H1-antihistamines display different chemical structures, pharmacokinetics and a potential for drug-drug and drug-food interactions. Drug-food interactions are known to reduce therapeutic effects of the medicine, as well as to induce a potent adverse drug reactions...

Cement burn is a common cause of chemical burns in France. They usually need surgical treatment. This retrospective study was performed among 49 patients, aged 21-71 years, admitted to the St Joseph-St Luc Hospital in Lyon, France. Patients were mainly male, fairly young (mean 44 years) and had a professional activity, although burns usually occurred at home. Burns were deep, on the lower limbs, and were not extensive (3% TBS). All but one patient needed grafting, performed on d13. LOS was eight days. Seven patients had to be admitted to a rehabilitation centre afterwards...

Floor dust samples were collected from Jordanian indoor environments (eight dwellings and an educational building) in Amman. Quantitative PCR (qPCR) analyses of selected fungal and bacterial groups were performed. The bacterial and fungal concentrations were also correlated with PAHs concentrations, which were previously measured in the same samples by using GC-MS. The bacterial and fungal concentrations varied significantly among and within the tested indoor environments. Based on the collected samples in the entrance area of the dwellings, the largest variation was found in Gram-negative bacteria and total fungi concentration...

In our analysis of 136 water samples from wetland environments (rice paddies, natural wetland sites, man-made water bodies) in rural areas of North-East Thailand, Burkholderia pseudomallei was most prevalent in rice paddies (15 of the 30 positive sites). The high prevalence in the water of rice fields is indicative of the inherent vulnerability of farmers in rural agricultural areas in this area of Thailand and likely other locations in the tropics. Nearly all B. pseudomallei-positive sites were found within the vicinity of a large wetland associated with the Chi River, in the month of July 2014...

Ocular trauma can lead to severe visual impairment and morbidity, depending on the anatomical structures affected. The main causes of ocular trauma include foreign bodies, impact by an object, falls, and chemicals. Most ocular traumas occur in children or young male adults. A meticulous slit lamp examination is crucial for assessing all anatomical structures. Trauma to the crystalline lens can result in dislocation, an intralenticular foreign body, cataract, fragmentation, and capsular breach. An intraocular lens (IOL) can endure subluxation or luxation under the conjunctiva, into the anterior chamber or the vitreous, or can be extruded...

The US FDA published new nutrition-labeling regulations in May 2016. For the first time since the implementation of the Nutrition Labeling and Education Act of 1990, the Daily Value (DV) for most vitamins will change, as will the units of measurement used in nutrition labeling for some vitamins. For some food categories, the Reference Amounts Customarily Consumed (RACCs) will increase to reflect portions commonly consumed on a single occasion. These regulatory changes are now effective, and product label changes will be mandatory beginning 26 July 2018...

A molecule is a quantum mechanical entity. "Watching motions and reactions of a molecule with our eyes" has therefore been a dream of chemists for a century. This dream has come true with the aid of the movies of atomic-resolution transmission electron microscopic (AR-TEM) molecular images through real-time observation of dynamic motions of single organic molecules (denoted hereafter as single-molecule atomic-resolution real-time (SMART) TEM imaging). Since 2007, we have reported movies of a variety of single organic molecules, organometallic molecules, and their assemblies, which are rotating, stretching, and reacting...

Islam and its followers had created a civilization that played very important role on the world stage for more than a thousand years. One of the most important specific qualities of the Islamic civilization is that it is a well-balanced civilization that brought together science and faith, struck a balance between spirit and matter and did not separate this world from the Hereafter. This is what distinguishes the Islamic civilization from other civilizations which attach primary importance to the material aspect of life, physical needs and human instincts, and attach greater attention to this world by striving to instantly satisfy desires of the flesh, without finding a proper place for God and the Hereafter in their philosophies and education systems...
