Leakage of small pockets of air in to soft tissues of cheek along vascular bundle is reported in a patient with ulcerated oral malignancy with history of recent biopsy. Leakage occurred during an attempt to puff the cheek during CT examination of oral cavity. Hereto undocumented phenomenon was self limiting and did not lead to clinical disability. Imaging appearance and likely mechanism of the complication are discussed.

In Italy, the congestive heart failure is the leading cause of hospitalization and despite advances in therapy, the long-term prognosis is poor. Congestive heart failure is associated with advanced varying degrees of chronic renal disease that identify the cardio-renal syndrome type 2. High-dose diuretic therapy often fail to solve the water overload that is frequently the cause of death. The resistance to diuretics aggravates the state of the patient's edema and consequently morbidity and mortality. In the acute stage, the extracorporeal ultrafiltration unable to repair over hydration but needs frequent access weekly or midweek at the dialysis center...

Four oat varieties and three product forms (porridge, cereal and snack bar) were assessed to determine the impact of oat phenolics on starch digestibility and intestinal glucose transport. α-Amylase activity was enhanced by 20 GAE μM (gallic acid equivalent) of phenolics extracted from oat (96.7-118%, p<0.05), while modestly inhibited at 500 GAE μM (83.0-95.4%). Maltose hydrolysis was reduced (49.6-82.4%, p<0.05), albeit with high IC50 values (500-940 GAE μM). Free and bound oat phenolic extracts dose-dependently attenuated transport of D-glucose-1,2,3,4,5,6,6-d7 by Caco-2 monolayers over 60 min...

[b]Abstract Introduction[/b]. Functional food plays an important role in the prevention, management and treatment of chronic diseases. One of the most interesting techniques of functional food production is extrusion-cooking. Functional foods may include such items as puffed cereals, breads and beverages that are fortified with vitamins, some nutraceuticals and herbs. Due to its pharmacological activity, chamomile flowers are the most popular components added to functional food. OBJECTIVE: Quantitative analysis of polyphenolic antioxidants, as well as comparison of various methods for the extraction of phenolic compounds from corn puffed cereals, puffed cereals with an addition of chamomile (3, 5, 10 and 20%) and from [i]Chamomillae anthodium...

Recently, the formation of carbonyl compound within e-cigarettes usage has been reported. The aim of this study was to develop a new analytical method for the direct analysis of carbonyl compounds in vaporized liquids. Two different types of e-cigarettes and different puff's duration have been evaluated, using a modified smoking machine for vapor generation. An isotopic dilution approach, based on deuterated internal standard addition to the e-liquid before filling the e-cigarette tank, has been developed. Carbonyl compounds have been sampled in vapors using a direct, simple, solid-phase microextraction technique with on-fiber derivatization...

PCBs appear in school air because many school buildings were built when PCBs were still intentionally added to building materials and because PCBs are also present through inadvertent production in modern pigment. This is of concern because children are especially vulnerable to the toxic effects of PCBs. Here we report indoor and outdoor air concentrations of PCBs and OH-PCBs from two rural schools and four urban schools, the latter near a PCB-contaminated waterway of Lake Michigan in the United States. Samples (n = 108) were collected as in/out pairs using polyurethane foam passive air samplers (PUF-PAS) from January 2012 to November 2015...

In this work, a mixed biofilm composed by Pseudomonas monteilii P26 and Gordonia sp. H19 was formed using polyurethane foam (PUF) as immobilization support, for crude oil removal from artificial sea water. Fresh immobilized cells and immobilized cells that were stored at 4°C for two months before use were assessed. The oil removal assays were carried out at microcosm scale at 4, 15 and 30°C. A viability loss of P. monteilii P26 was observed after the storage. The highest removal value (75%) was obtained at 30°C after 7days using fresh immobilized cells on PUF...

Introduction: The purpose was to measure nicotine levels to the tobacco and levels emitted to the aerosol of a heat-not-burn product (HnB, IQOS) compared to e-cigarettes (ECs) and a tobacco cigarette. Methods: The HnB device and regular and menthol sticks were purchased from Italy. Three types of ECs (ciga-like, eGo-style and variable wattage) and a commercially-available tobacco cigarette were also tested. A custom-made liquid containing 2% nicotine was used with ECs...

Solid-solution partitioning coefficient (Kd) and plant uptake factor (PUF) largely determine the solubility and mobility of soil Cd to food crops. A four-year regional investigation was conducted in contaminated vegetable and paddy fields of southern China to quantify the variability in Kd and PUF. The distributions of Kd and PUF characterizing transfers of Cd from soil to vegetable and rice are probabilistic in nature. Dynamics in soil pH and soil Zn greatly affected the variations of Kd. In addition to soil pH, soil organic matter had a major influence on PUF variations in vegetables...

Fucoidan, a fucose-containing sulfated polysaccharide with diverse biological functions, is mainly recovered from brown algae. In this study, we utilized a compressional-puffing process (CPP) to pretreat Sargassum crassifolium (SC) and extracted fucoidans from SC by warm water. Three fucoidan extracts (SC1: puffing at 0 kg/cm²; SC2: puffing at 1.7 kg/cm²; and SC3: puffing at 6.3 kg/cm²) were obtained, and their composition, and antioxidant and neuroprotective activities were examined. The results suggest that CPP decreased the bulk density of algal samples, expanded the algal cellular structures, and eliminated the unpleasant algal odor...

The long-proposed use of open-cell polyurethane foam (PUF) as a convenient 'solid-phase extractant' for aqueous organic compounds has been hindered by a critical lack of understanding on the underlying specificity of its extraction mechanism. In this work, we tasked ourselves to understand the hierarchy of molecular structure, properties, and partitioning characteristics of compounds in PUF and aqueous phase by targeting lipophilic phenolic compounds (LPCs) as a group of primary targets for PUF extraction. Using six structurally related bisphenol analogs as comparative probes, we identified molecular lipophilicity and H-bond acidity as key molecular attributes that governed their extractability by PUF...

Members of the yeast family of PUF proteins bind unique subsets of mRNA targets that encode proteins with common functions. They therefore became a paradigm for post-transcriptional gene control. To provide new insights into the roles of the seemingly redundant Puf1 and Puf2 members, we monitored the growth rates of their deletions under many different stress conditions. A differential effect was observed at high CaCl2 concentrations, whereby puf1Δ growth was affected much more than puf2Δ, and inhibition was exacerbated in puf1Δpuf2Δ double knockout...

Tree bark is considered as an effective passive sampler for estimating the atmospheric status of pollutants. In this study, we conducted a national scale tree bark sampling campaign across China. Concentration profiles revealed that Eastern China, especially the Jing-Jin-Ji region (including Hebei Province, Beijing and Tianjin) was a hot spot of bark DDT pollution. The enantioselective accumulation of o,p'-DDT was observed in most of the samples and 68% of them showed a preferential depletion of (+)-o,p'-DDT...

Vapour products have demonstrated potential to be a lower-risk alternative to cigarettes. The present study describes a novel hybrid tobacco product that combines a warm aerosol stream generated by an electronic vaporisation mechanism with tobacco top flavour from cut tobacco. During operation, the aerosol stream released from the vapour cartomiser is passed through a bed of blended cut tobacco by the puffing flow, elevating the tobacco temperature and eluting volatile tobacco flavour components. A preliminary but comprehensive analysis of the aerosol composition of the hybrid tobacco product found that emissions were dominated by the control vapour formulation...

To offer an enhanced and well-controlled nicotine delivery from the refill liquid to the aerosol is a key point to adequately satisfy nicotine cravings using electronic nicotine delivery systems (ENDS). A recent high-power ENDS, exhibiting higher aerosol nicotine delivery than older technologies, was used. The particle size distribution was measured using a cascade impactor. The effects of the refill liquid composition on the nicotine content of each size-fraction in the submicron range were investigated. Nicotine was quantified by liquid chromatography coupled with tandem mass spectrometry...

Polyurethane foam membrane filled with humic acid-chitosan crosslinked gels (HA-CS-PUF) for dye removal was prepared by soaking the foams into humic acid-chitosan (HA-CS) crosslinked gels and hot-pressing them into membranes. Scanning electron microscope, derivative thermogravimetry and X-ray photoelectron spectroscopy were used to characterize the HA-CS-PUF membrane. Results showed that the interaction of HA and CS was mainly through ionic cross-linking between carboxyl and protonated amino groups. Three types of dyes, including positively charged methylene blue (MB), neutrally charged rhodamine B (RB) and negatively charged methyl orange (MO), were used to test membranes properties through static adsorption and membrane filtration experiments...

BACKGROUND: The aim of this work was to develop a puffed quinoa bar with beehive products of high content of phenolic compounds, based on acceptability and perception of consumers. A rotational central composite design of three variables (honey, pollen and propolis) was used for food product formulation. The responses to optimize were sensorial acceptability and polyphenol content. Next to acceptability a CATA test was performed with 115 consumers. Preference maps were used to relate acceptability and sensorial attributes of bars that cause rejection or acceptance...
