Modern agriculture provides the potential for sustainable feeding of the world's increasing population. Up to the present moment, genetically modified (GM) products have enabled increased yields and reduced pesticide usage. Nevertheless, GM products are controversial amongst policy makers, scientists and the consumers, regarding their possible environmental, ecological, and health risks. Scientific-and-political debates can even influence legislation and prospective risk assessment procedure. Currently, the scientifically-assessed direct hazardous impacts of GM food and feed on fauna and flora are conflicting; indeed, a review of literature available data provides some evidence of GM environmental and health risks...

AIM: Laparoscopic rectal surgery is associated with a steep learning curve and high conversion rate despite progress in equipment design and consistent practice. The robotic system has shown the advantage over laparoscopic approach due to stable three-dimensional views, improved dexterity and better ergonomics. These factors make the robotic approach more favourable for rectal surgery. The aim of this study was to compare the perioperative outcomes of laparoscopic and robotic rectal cancer surgery in high-risk patients...

Cytotoxic T lymphocyte (CTL)-based immunotherapies have had remarkable success at generating objective clinical responses in patients with advanced metastatic melanoma.  Although the melanocyte differentiation antigens (MDAs) MART-1, PMEL, and tyrosinase were among the first melanoma tumor-associated antigens identified and targeted with immunotherapy, expression within normal melanocytes of the eye and inner ear can elicit serious autoimmune side effects, thus limiting their clinical potential as CTL targets...

OBJECTIVES: We sought to examine the prognostic utility of left ventricular (LV) global longitudinal strain (GLS) in asymptomatic patients with ≥III+ aortic regurgitation (AR), an indexed LV end-systolic dimension of <2.5 cm/m(2), and preserved left ventricular ejection fraction (LVEF). BACKGROUND: Management of asymptomatic patients with severe chronic AR and preserved LVEF is challenging and is typically based on LV dimensions. METHODS: We studied 1,063 such patients (53 ± 16 years; 77% men) seen between 2003 and 2010 (excluding those with symptoms, obstructive coronary artery disease, acute AR/dissection, aortic/mitral stenosis, more than moderate mitral regurgitation, and previous cardiac surgery)...

A three-year field monoculture trial of Radix pseudostellariae and complementary laboratory studies were conducted to further elucidate the underlying mechanism responsible for significant decreases in the biomass yield and quality of R. pseudostellariae under continuous monoculture regimes. HPLC analysis indicated that continuous monoculture soil was rich in organic acids, which had cumulative effects over time. Further analysis suggested that the application of a mixture of organic acids significantly promoted growth of pathogenic fungi, and increased the expression of chemotaxis-related gene (cheA) and biofilm formation of the specific pathogenic Kosakonia sacchari...

Cadmium (Cd) contamination of soil and food crops is a ubiquitous environmental problem that has resulted from uncontrolled industrialization, unsustainable urbanization and intensive agricultural practices. Being a toxic element, Cd poses high threats to soil quality, food safety, and human health. Land is the ultimate source of waste disposal and utilization therefore, Cd released from different sources (natural and anthropogenic), eventually reaches soil, and then subsequently bio-accumulates in food crops...

Vascular headache and chronic rhinosinusitis (CRS) are diseases that share similar symptoms and demographics, including headache, facial pain and nasal symptoms. Contribution of chronic sinusitis as a cause of chronic headache is controversial, as there are scarce studies to know incidence of vascular headache in patients with CRS. To evaluate incidence of vascular headache in patients with CRS. Using descriptive study design, group of 100 patients with symptoms of CRS with headache were included in study. Patients underwent surgical management and 3% managed medically...

AIMS: Intracoronary adenosine (ICA) yields similar fractional flow reserve (FFR) results as the "gold standard" of intravenous adenosine (IVA). Whether they have similar prognostic significance is unknown. METHODS AND RESULTS: 576 patients with 787 lesions in whom PCI was deferred based on FFR >0.75 were studied. Primary outcome was the first major adverse cardiovascular event [MACE defined as death, myocardial infarction (MI), or target vessel revascularization (TVR)] and secondary outcome was a composite of MI and target vessel failure (TVF)...

A 56-year hypertensive, multiparous woman presented to the cardiology unit with Canadian Cardiovascular Society (CCS) class-III angina and worsening dyspnea for the past few weeks. Her clinical examination showed high blood pressure and mid-systolic crescendo-decrescendo murmur radiating to carotids. However, there was no radio-femoral delay or significant blood pressure difference between her arms. Her transthoracic echocardiography (TTE) revealed moderate aortic stenosis (AS) and mid cavity left ventricular outflow (LVO) obstruction...

OBJECTIVE: Cognitive impairment poses communication challenges in primary care. Although family "companions" commonly attend primary care visits of older adults with cognitive impairment, little is known about how their involvement affects communication. Therefore, we sought to understand how companion involvement affects the quality of primary care visit communication for older adults with cognitive impairment. METHODS: Cross-sectional, descriptive qualitative study participants were as follows: (1) English-speaking adults age 65 or older with mild, moderate, or severe cognitive impairment; (2) family members or other unpaid companions who accompany older adults to primary care visits; and (3) primary care clinicians...

Synthesis of Nobel metal nanoparticles, play a key role in the field of medicine. Plants contain a substantial number of organic constituents, like phenolic compounds and various types of glycosides that help in synthesis of metal nanoparticles. Synthesis of metal nanoparticles by green method is one of the best and environment friendly methods. The major significance of the green synthesis is lack of toxic by-products produced during metal nanoparticle synthesis. The nanoparticles, synthesized by green method show various significant biological activities...

Anthropogenic activities have transformed the global geochemical cycling of heavy metals (HMs). Many physical, chemical and biological methods are used to reduce the toxicity of HMs to humans, plants and environment. This study aimed to investigate the immobilization and phytotoxicity reduction of HMs after application of bamboo biochar (BB) in mine-polluted soil in Feng county (FC) and Tongguan (TG). The results showed that BB application to contaminated soil immobilized HMs (Zn, Pb, Cd and Cu). The soil pH and EC increased and the bioavailability of HMs decreased in FC and TG, whereas Pb and Cu increased in TG soil...

Ischemic heart disease (IHD) remains the single most common cause of death worldwide. Ischemic cardiomyopathy is a major sequel of coronary artery disease. The economic health burden of IHD is substantial. In patients with old myocardial infarction (OMI), the extent of viable myocardium (VM) directly affects the short- and long-term outcome. There is a considerable collection of observational data showing substantial improvement in patients with significant left ventricular dysfunction when the need for revascularization is guided by preoperative assessment of viability and hibernation...

The aim of this study is to evaluate the adhesion ability of okra gum, which is gaining popularity as a tablet binder. For this purpose, gum was extracted from okra pods, and the binding strength of different concentrations (1%, 3%, and 5%) was determined quantitatively. Additionally, naproxen sodium tablets were prepared by using okra gum as a binder and were evaluated for their properties including hardness, friability, disintegration time, and dissolution rate. The binding strength values were compared with that of pre-gelatinized starch, a commonly used tablet binder...

BACKGROUND: Research investigating mammography screening has often reported low mammography self-efficacy and breast cancer fear contribute to underutilization of mammography. This study aimed to examine the reliability and validity of Champion's Mammography Self-efficacy Scale (CMSS) and Champion's Breast Cancer Fear Scale (CBCFS) in a sample of Iranian women. METHODS: The adapted instruments were administered to a community sample of 482 women aged 40 years or older...
