Enzyme-treated asparagus extract (ETAS) is prepared from the lower, residual parts of asparagus, and some functionalities, such as anti-oxidative and neuroprotective activities, have been suggested. The purpose of the present study was to investigate the effects of ETAS on photoaging in the epidermal layer of the skin using cultured keratinocytes. Normal human epidermal keratinocytes were irradiated or left unirradiated with UV-B (10 mJ/cm2 ) and incubated with ETAS (0.5 or 2 mg/mL) or vehicle. After 3 or 13 h, molecular examinations were performed, and after 24 or 48 h, cell viabilities were determined by a CCK-8 assay...

Asparagus officinalis are perennial plants that require re-planting every 10–20 years. The roots are traditionally mulched in the soil or treated as waste. The A. officinalis roots (AR) contain valuable bioactive compounds that may have some health benefiting properties. The aim of this study was to investigate the total polyphenol and flavonoid contents (TPC and TFC, respectively) and antioxidant (2,2-diphenyl-1-picrylhydrazyl (DPPH), Oxygen Radical Absorbance Capacity (ORAC) and Ferric Reducing/Antioxidant Power (FRAP) assays) activities of New Zealand AR extract...

Asparagus (Asparagus officinalis L.) is a widely cultivated perennial veritable and can be harvested more than ten years. However, the crop quality and yield decline after a few year's cultivation, which is called "asparagus decline". Even though those asparagus plants were replaced with new young asparagus plants, the productivity and quality of the crop remain relatively low, which is known as a "asparagus replant problem". One of the possible reasons for "asparagus decline" and "asparagus replant problem" is thought to be autotoxicity of asparagus...

Genetic maps are a prerequisite for quantitative trait locus (QTL) analysis, marker-assisted selection (MAS), fine gene mapping, and assembly of genome sequences. So far, several asparagus bean linkage maps have been established using various kinds of molecular markers. However, these maps were all constructed by gel- or array-based markers. No maps based on sequencing method have been reported. In this study, an NGS-based strategy, SLAF-seq, was applied to create a high-density genetic map for asparagus bean...

Despite decades of research, malignant tumors are extremely difficult to eliminate with conventional methods. Although surgical resection potentially eradicates the problem, only a few cases are suitable for operation, and other approaches often involve harmful consequences. Revolutionary methods are desperately needed to improve patient outcomes and diminish harmful side effects. Myeloid-derived suppressor cells (MDSCs), downregulators of the innate and adaptive immune systems, have been widely studied over the past 2 decades...

Past investigations have shown that various plant extracts are capable of promoting longevity in lower model organisms like Caenorhabditis elegans, Drosophila melanogaster, Saccharomyces cerevisiae, Bombyx mori etc. Longevity studies on such organisms provide a foundation to explore anti-aging efficacies of such plant extracts in higher organisms. Plant extracts of acai palm, apple, asparagus, blueberry, cinnamon, cocoa, Damnacanthus, maize, milk thistle, mistletoe, peach, pomegranate, Rhodiola, rose, Sasa, turmeric, and Withania have extended lifespan in lower model organisms via diverse mechanisms like insulin like growth factor (IGF) signaling pathway, and antioxidant defense mechanisms...

We used electron cryo-tomography and subtomogram averaging to investigate the structure of complex I and its supramolecular assemblies in the inner mitochondrial membrane of mammals, fungi, and plants. Tomographic volumes containing complex I were averaged at ∼4 nm resolution. Principal component analysis indicated that ∼60% of complex I formed a supercomplex with dimeric complex III, while ∼40% were not associated with other respiratory chain complexes. The mutual arrangement of complex I and III2 was essentially conserved in all supercomplexes investigated...

Zinc oxide nanoparticles (ZnO NP) may be present in food packaging, which would put consumers at risk of NP ingestion. There is little information on the amount of ZnO NP that are present in food packaging and the effects of ZnO exposure on intestinal function. To estimate physiologically relevant ZnO exposures, foods that are naturally low in zinc (Zn), but are commonly packaged with ZnO NP, such as tuna, corn, and asparagus, were analyzed with inductively coupled plasma mass spectrometry (ICP-MS). It was found that the Zn present in a serving of these foods is approximately one hundred times higher than the recommended dietary allowance...

Flavonoids have been demonstrated to possess an anti-depressant effect and less adverse effects than tricyclic anti-depressants. For this reason, flavonoids in natural products have attracted growing attention. Rutin is a glycoside flavonoid which belongs to an important class of flavonoids, abundantly found in plants, such as buckwheat seeds, asparagus, red pepper, apples, citrus fruits and leaves of many herbs such as rosemary, dandelion or sage, and black and green tea.  It is a vital nutritional component of food stuff...

The food-borne bacterial pathogen, Salmonella enterica, can utilize fructose-asparagine (F-Asn) as its sole carbon and nitrogen source. F-Asn is the product of an Amadori rearrangement following the nonenzymatic condensation of glucose and asparagine. Heating converts F-Asn via complex Maillard reactions to a variety of molecules that contribute to the color, taste, and aroma of heated foods. Among these end derivatives is acrylamide, which is present in some foods, especially in fried potatoes. The F-Asn utilization pathway in Salmonella, specifically FraB, is a potential drug target because inhibition of this enzyme would lead to intoxication of Salmonella in the presence of F-Asn...

This review presents the current trends in anaphylaxis management discussed at the fourth International Network for Online-Registration of Anaphylaxis (NORA) conference held in Berlin in April 2017. Current data from the anaphylaxis registry show that Hymenoptera venom, foods, and pharmaceutical drugs are still among the most frequent triggers of anaphylaxis. Rare triggers include chicory, cardamom, asparagus, and goji berries. A meta-analysis on recent trends in insect venom anaphylaxis demonstrated for the first time that, although data on the efficacy of insect venom immunotherapy is limited, the occurrence of severe reactions upon repeated sting events can be prevented and patients' quality of life improved...
