Minimally processed pomegranate rapidly loses its overall quality because of high water loss and microbial contamination. Nano-ZnO in combination with carboxymethyl cellulose (CMC) coating was used on pomegranate arils. Arils were dipped for 4min in distilled water (control), 0.1 or 0.2% (w/v) nano-ZnO suspension and then ZnO treated arils were coated with 0.5% (w/v) CMC and stored for 12days at 4°C. Coatings decreased total yeast+mold during 12days of storage while total mesophilic bacteria was decreased during 6days of storage...

A novel peptidomics approach was used to discover cold-induced peptides in loquat fruit. Twenty unique peptides derived from 18 proproteins were identified, and they were involved in sugar signalling, protein metabolism and stress response. The quantitative analysis revealed 7 peptides with more than 2-fold upregulation, especially a 4.96-fold increase detected in the phytosulfokine (PSK) peptide. To further evaluate effects of PSK1 on fruit chilling tolerance, weight loss, firmness and internal browning were investigated in PSK1-treated loquat fruit at 0°C...

BACKGROUND: Brassica oleracea includes a number of important crop types such as cabbage, cauliflower, broccoli and kale. Current climate conditions and weather patterns are causing significant losses in these crops, meaning that new cultivars with improved tolerance of one or more abiotic stress types must be sought. We assayed genetically fixed B. oleracea lines belonging to a Diversity Fixed Foundation Set (DFFS) for their response to seedling stage-imposed drought, flood, salinity, heat and cold stress...

Discrepancies exist between the preferred temperature range for mice (26 to 32 °C) and current recommendations (20 to26 °C), which may alter metabolism and negatively affect studies using mice. Previous research indicates that nesting materialcan alleviate cold stress in mice; therefore, we sought to determine the effects of the amount of nesting material provided(0, 6, or 12 g) on heat energy loss and energy balance in 3 mouse strains housed at currently recommended temperatures duringthe daytime, a period of presumed inactivity...

Adipose tissue, defined as white adipose tissue (WAT) and brown adipose tissue (BAT), is a biological caloric reservoir; in response to over-nutrition it expands and, in response to energy deficit, it releases lipids. The WAT primarily stores energy as triglycerides, whereas BAT dissipates chemical energy as heat. In mammals, the BAT is a key site for heat production and an attractive target to promote weight loss. The autonomic nervous system (ANS) exerts a direct control at the cellular and molecular levels in adiposity...

BACKGROUND: Pheochromocytoma (PHEO) is a rare tumor of the adrenal medulla and sympathetic ganglion that produces the catecholamines norepinephrine and epinephrine. Traditionally, approximately 10% of PHEOs were thought to be malignant, but recent developments in PHEO research have noted that specific genetic mutations are associated with higher risk of metastatic spread. CASE REPORT: We report the case of a 71-year-old female who presented with abdominal pain in September 2009 when she was 64 years old...

Modified atmosphere packaging (MAP) enhanced the quality and storability of Ligularia fischeri. Oxygen transmission rate (OTR) films were used as a MAP. MAP storage displayed lower fresh weight loss than perforated film. The oxygen, carbon dioxide, and ethylene concentration were properly maintained by a 10,000 cc OTR packaging film at 8 °C and 30,000 cc OTR packaging film at 24 °C. On the last day of storage, the off-odor, such as the acetaldehyde and ethanol concentration, was the lowest in the 10,000 cc OTR film at 8 °C and 30,000 cc OTR film at 24 °C treatments...

Cold shock proteins (CSPs) enhance acclimatization of bacteria to adverse environmental circumstances. The Escherichia coli CSP genes CspA and CspB were modified to plant-preferred codon sequences and named as SeCspA and SeCspB. Overexpression of exogenous SeCspA and SeCspB in transgenic Arabidopsis lines increased germination rates, survival rates, and increased primary root length compared to control plants under drought and salt stress. Investigation of several stress-related parameters in SeCspA and SeCspB transgenic wheat lines indicated that these lines possessed stress tolerance characteristics, including lower malondialdehyde (MDA) content, lower water loss rates, lower relative Na(+) content, and higher chlorophyll content and proline content than the control wheat plants under drought and salt stresses...

Fariborz Habibi, Asghar Ramezanian
The effects of putrescine (Put) treatment on anthocyanin concentrations and other bioactive compounds of two blood orange ('Moro' and 'Tarocco') cultivars during cold storage have been investigated. Put at 0, 1 and 2mM were applied to fruit by vacuum infiltration at 26.665kPa for 8min and then stored at 5°C, and 90% RH for 60days, plus a simulated shelf life of 2days at 20°C. Put treatment maintained higher fruit firmness and reduced weight loss during storage. Anthocyanin, total phenolic content (TPC), ascorbic acid content, and antioxidant activity were also higher in treated fruit than the control during storage...

BACKGROUND: The aim of this study was to investigate the influence of body fat percentage and its distribution on sensory detection and pain sensitivity responses to experimentally induced noxious stimuli in otherwise pain-free individuals. METHODS: Seventy-two participants were divided into three equal groups according to their body mass index (BMI: normal, overweight and obese). Percentage body fat was estimated using a four-site skinfold method. Measurements of cold pressor pain threshold, tolerance and intensity; contact thermal sensory detection and heat pain threshold and tolerance (TSA-II - NeuroSensory Analyzer, Medoc); and blunt pressure pain threshold (algometer, Somedic SenseLab AB) were taken at the waist and thenar eminence...

BACKGROUND: Widely used as a weight loss supplement, trans-10,cis-12 conjugated linoleic acid (10,12 CLA) promotes fat loss in obese mice and humans, but has also been associated with insulin resistance. OBJECTIVE: We therefore sought to directly compare weight loss by 10,12 CLA versus caloric restriction (CR, 15-25%), an acceptable healthy method of weight loss, to determine how 10,12 CLA-mediated weight loss fails to improve glucose metabolism. METHODS: Obese mice with characteristics of human metabolic syndrome were either supplemented with 10,12 CLA or subjected to CR to promote weight loss...

Despite the importance of litter decomposition under snow cover in boreal forests and tundra, very little is known regarding the characteristics and functions of litter-decomposing fungi adapted to the cold climate. We investigated the decomposition of oak leaves in a heavy snowfall forest region of Japan. The rate of litter weight loss reached 26.5% during the snow cover period for 7 months and accounted for 64.6% of the annual loss (41.1%). Although no statistically significant lignin loss was detected, decolourization portions of oak leaf litter, which was attributable to the activities of ligninolytic fungi, were observed during snow cover period...
