Vagal stimulation for treating syncope by cardioneuroablation without pacemaker implantation

Vagal Stimulation for Treating Syncope by Cardioneuroablation without Pacemaker Implantation

The heart has a dense innervation that permanently regulates its activity. It is the autonomic nervous system, constituted by two antagonistic divisions, the parasympathetic and the sympathetic. The latter stimulates the heart, increasing cardiac rate and contraction

Molecular defense adopted by sea urchin embryos to cope with Nickel

Molecular defense adopted by sea urchin embryos to cope with Nickel

Nickel (Ni) is a natural constituent of the Earth’s crust and, together with its compounds, it is used in many industrial and commercial applications. At very low doses, Ni carries out many physiological roles in biochemical processes

High seroprevalence for Crimean-Congo haemorrhagic fever virus in ruminants in the absence of reported human cases

CCHFV seroprevalence in livestock in all regions in Bulgaria. District specific prevalence rates are indicated in the map

Crimean-Congo haemorrhagic fever (CCHF) is a severe tick-borne zoonotic disease in humans caused by CCHF virus. Close contact with viraemic livestock was shown as one of the main causes of the infection. Detection of CCHF virus specific

Efficient catalyst-free removal technique of benzene in air using a vacuum ultraviolet excimer lamp

Benzene (C6H6) is a typical VOC (volatile organic compound) pollutant which is widely detected in the atmosphere of both indoor and industrial areas. Especially in indoor environment, it would make a great influence on human health for

Vitamin D deficiency is a sign of poor health in chronic obstructive pulmonary disease

Vitamin D deficiency is a sign of poor health in COPD

Vitamin D is an important hormone in growth and bone metabolism. Vitamin D deficiency is highly prevalent worldwide and causes growth retardation and rickets in children and osteomalacia in adults. However, the role of vitamin D deficiency

Camphor biodegradation by Pseudomonas putida plays a key role in carbon cycling in the biosphere

Camphor biodegradation by Pseudomonas putida plays a key role in carbon cycling in the biosphere

The key role of microorganisms in promoting carbon cycling in the biosphere is well illustrated by the biodegradation of the natural plant terpenoid camphor by Pseudomonas putida ATCC 17453. Research has established that several different monooxygenases (cytochromeP450

Routine imaging in patients with follicular lymphoma in remission

Routine imaging in patients with follicular lymphoma in remission

B-cell lymphomas are a heterogeneous group of malignancies originating from B lymphocytes. Modern day chemotherapy is effective in inducing disease remission in a large percentage of patients for most of the subtypes. Some of these subtypes, the

Authentication of Egyptian blossom honeys

Floral discrimination of clover and citrus honeys from Egypt against ‘’unknown’’ honeys from Greece based on 11 easily assessable physicochemical parameters and discriminant analysis

Twenty-two blossom honey samples (clover and citrus honeys) were collected from the greater Cairo area during harvesting year 2014-2015. The main purpose of the present study was to characterize the aforementioned honey types and to investigate whether

Functional significance of interhelical interactions between aspartic acid and cysteine residues in microbial rhodopsin

proton-pump type microbial rhodopsins

Microbial rhodopsins are photoreceptive seven-transmembrane proteins that contain all-trans retinal as a chromophore. Upon photon absorption, these proteins undergo a cycling photoreaction, where first the initial trans-to-cis isomerization of retinal induced by illumination leads to the formation

Treatment of experimental eye inflammation with a single subconjunctival injection of liposomal steroid

Treatment of experimental eye inflammation

Non-infectious anterior uveitis is an inflammatory condition in the front of the eye that can potentially lead to blindness. The current gold standard for treatment is with steroid eyedrops.  However, this treatment has several disadvantages. Very little

Simplified molecular diagnostics on a chip for point-of-care diagnostics

Simplified Molecular Diagnostics on a Chip for Point-of-Care Diagnostics

Analysis of blood, urine, and saliva often serves as the primary basis of diagnosis and treatment. Clinical specimens contain signature molecules (‘markers’) such as proteins and nucleic acids that are indicators of infection, cancer, and other diseases,

Do patients return to sport activities after total hip replacement?

Pooled data for number of patients participating in any sport pre- and postoperatively

Total hip replacement (THR) is a successful procedure to treat end-stage hip osteoarthritis. The procedure is increasingly performed in adults of working age, who often wish to return to highly demanding activities, including a return to sports

Reactive oxygen species, Devil or Angel?

Reactive oxygen species

Reactive oxygen species (ROS) have an amazing oxidative potential with oxidative stress and could abolish the integrity of living cells. Vigorous production of ROS can damage mitochondria and DNA, which would persistently destroy the cells and might

How cancer cells communicate with nervous and immune systems

In the last decade, studies have shown that cancer cells can influence their environment and bi-directionally communicate with other systems including immune and nervous systems. The neuro-immune interaction is a key player in influencing cancer development and

Using a uniform definition for growth restricted fetuses

sentation of the possible overlap between FGR and SGA and between AGA and LGA

Once a woman gets pregnant, the fetus develops and grows through exchange of oxygen and nutrients between the mother and fetus in the placenta. Each fetus has its own growth potential. Therefore, some fetuses are smaller than

Can “low calorie”-oil enhance the secretion of incretin hormones with beneficial effects on diabetic patients?

Time courses for plasma GLP-1 following ingestion of olive oil and carrot (squares), C4-dietary oil and carrot (circles) and carrot alone (crosses).

When the human body digests dietary fat (triacylglycerol), hormones from the intestine called incretins are released from the small intestine. These hormones stimulate insulin release and inhibit food intake. The mechanism for the fat-induced incretin release involves
