A high-surface-area nanoporous carbon (NPC) has been successfully synthesized by using the metal-organic framework ZIF-90 as both the template and precursor together with furfuryl alcohol as a secondary carbon source. The prepared ZIF-90 templated NPC (ZIF-90-NPC) was then coated onto a stainless steel wire by a simple physical adhesion approach to prepare solid-phase microextraction (SPME) fiber. By coupling the ZIF-90-NPC coated fiber-based SPME with gas chromatography-microelectron capture detection (GC-μECD), the developed method gave a large enhancement factor (984-2869), low limit of detection (0...

Osteosarcoma is the most frequent primitive malignant bone tumor affecting adolescents and young adults worldwide. The tumor exhibits aggressive growth in the primary site and readily metastasizes to other organs. There has been no significant improvement in the 5-year survival rate since the 1970s and the figure remains at 60-70%. In addition, the side effects of chemotherapeutic drugs and resistance to chemotherapy compromise the effects of treatment for osteosarcoma. In recent years, the development of flavonoids drugs inhibiting carcinogenesis is attracting great interest in the scientific community...

(Poly)phenols are a large group of dietary compounds present in fruits and vegetables and for which its consumption is associated with health beneficial effects. After ingestion (poly)phenols suffer extensive metabolisation and the identification of their metabolites is an emerging area, since these metabolites are considered the effective bioactive molecules in human organism. However, a lack of commercially available standards has hampered the study of metabolite bioactivity and the structural exact confirmation in biological samples...

BACKGROUND: Passiflora (passionflowers) makes an excellent model for studying plant evolutionary development. They are mostly perennial climbers that display axillary tendrils, which are believed to be modifications of the inflorescence. Passionflowers are also recognized by their unique flower features, such as the extra whorls of floral organs composed of corona filaments and membranes enclosing the nectary. Although some work on Passiflora organ ontogeny has been done, the developmental identity of both Passiflora tendrils and the corona is still controversial...

Since the 1990s, a large number of studies around the world have reported the presence of perchlorate in different types of environmental matrices. In view of their inherent characteristics, such as high solubility, mobility, persistence, and low affinity for the surface of soil, perchlorates are mobilized through the water-soil system and accumulate in edible plant species of high human consumption. However, the ingestion of food products containing perchlorate represents a potential health risk to people due to their adverse effects on thyroid, hormone, and neuronal development, mainly in infants and fetuses...

BACKGROUND: Tens of millions of children regularly participate in out-of-school-time (OST) programs, providing an opportunity for child health promotion. Most research on OST has focused on structured, staff-led after-school programs, as opposed to volunteer-led programs such as enrichment programs and youth sports. The aim of this study was to describe snacks, beverages, and physical activity (PA) practices in volunteer-led OST programs across five organizations in three states. METHODS: An online survey including the Out-of-School-Time Snacks, Beverages, and Physical Activity Questionnaire was distributed to 1,695 adult leaders of enrichment and youth sports programs serving 5-12 year-old children in Maine, Massachusetts, and New Hampshire, USA...

The anaerobic co-digestion of organic fraction of municipal solid waste (OFMSW) and fruit and vegetable waste (FVW) was evaluated in terms of biogas and methane yield, volatile solids (VS) removal rate and stability of the process. The batch experiment was conducted in mesophilic conditions (35°C), with four different OFMSW/FVW ratios (VS basis) of 1/0, 1/1, 1/3, and 0/1. The methane yield from the co-digestion was higher than the mono-digestion for OFMSW and FVW. The optimal mixing ratio of OFMSW/FVW was found to be 1/3...

In geographical locations with a short vegetative season and continental climate that include Western Siberia, growing primocane fruiting raspberry varieties becomes very important. However, it is necessary to help the plants to overcome the environmental stress factors. This study aimed to evaluate the impact of the pre-planting treatment of primocane fruiting raspberry root system with Bacillus strains on the following plant development under variable environmental conditions. In 2012, Bacillus subtilis RCAM В-10641, Bacillus amyloliquefaciens RCAM В-10642, and Bacillus licheniformis RCAM В-10562 were used for inoculating the root system of primocane fruiting raspberry cultivar Nedosyagaemaya before planting...

Cecropins and defensins are important antimicrobial peptides in insects and are inducible after injection of immune triggers. In this study, we cloned the cDNAs of two antimicrobial peptides (AMPs), cecropin-2 (BdCec-2) and defensin (BdDef) from Bactrocera dorsalis (Hendel), a serious pest causing great economic losses to fruits and vegetables. The BdCec-2 sequence of 192bp encodes a protein of 63 amino acids residues with a predicted molecular weight of 6.78kD. The 282bp cDNA of BdDef encodes a protein of 93 residues with a predicted molecular weight of 9...

Studies suggest diets rich in fruit and vegetables reduce bone loss, although the specific compounds responsible are unknown. Substrates for endogenous nitric oxide (NO) production, including organic nitrates and dietary nitrate, may support NO production in age-related conditions, including osteoporosis. We investigated the capability of dietary nitrate to improve NO bioavailability, reduce bone turnover and loss. Six-month-old Sprague Dawley rats [30 ovariectomized (OVX) and 10 sham-operated (sham)] were randomized into 3 groups: (1) vehicle (water) control, (2) low-dose nitrate (LDN, 0...

BACKGROUND: Increased consumption of fruits and vegetables significantly reduces the risk of cardio-vascular disease. This beneficial effect on the human organism is ascribed to the antioxidant compounds these foods contain. Unfortunately, many products, particularly vegetables, need to be subjected to thermal processing before consumption. The aim of this study was to determine the effect of such thermal treatment on the antioxidant capacity and pigment contents in separated fractions of violet pigments (betacyanins) and yellow pigments (betaxanthins and betacyanins)...

Over the last few decades, polyphenols, and flavonoids in particular, have attracted the interest of researchers, as they have been associated with the health-promoting effects derived from diets rich in vegetables and fruits, including moderate wine consumption. Recent scientific evidence suggests that wine polyphenols exert their effects through interactions with the gut microbiota, as they seem to modulate microbiota and, at the same time, are metabolized by intestinal bacteria into specific bioavailable metabolites...

The use of genetic model organisms such as Caenorhabditis elegans has led to seminal discoveries in biology over the last five decades. Most of what we know about C. elegans is limited to laboratory cultivation of the nematodes that may not necessarily reflect the environments they normally inhabit in nature. Cultivation of C. elegans in a 3D habitat that is more similar to the 3D matrix that worms encounter in rotten fruits and vegetative compost in nature could reveal novel phenotypes and behaviors not observed in 2D...

Akari Shibata, Gaku Kudo
In sexually dimorphic plants, resource allocation to reproduction often differs between sex morphs. In gynodioecious species, i.e. coexisting hermaphrodite and female plants within a population, females often produce more fruits than hermaphrodites. Since fruit production is costlier than flower production, hermaphrodites and females may regulate flower and fruit production differently in response to resource availability. To clarify the gender-specific strategies of reproductive allocation, we assessed sexual dimorphism in reproductive traits, size-dependent resource allocation, morphological traits, and photosynthetic capacity in a natural population of a gynodioecious shrub, Daphne jezoensis Hermaphrodites had larger flowers and increased flower number with plant size at a rate greater than females, but showed consistently smaller fruit production...

Gibberellins (GAs) play a crucial role in growth and development of the tomato fruit. Previously published studies focusing on the effect of GAs on tomato fruits used chemical treatments, constitutive overexpression or silencing of GA biosynthetic and catabolic genes globally throughout the plant. Fruit-specific overexpression of GA catabolic enzyme genes GA2-oxidases (GA2oxs), however, may provide an alternative method to study the role of endogenous GAs on the fruit development. In this study, we have identified 11 SlGA2ox proteins in tomato that are classified into three subgroups...
