The first article of a two-article series presents pervaporation (PV) of volatile aroma compounds from fruit juice hydrolates (plum, apple, blackcurrant and cherry). The purpose of this research was to evaluate the effectiveness of fruit juice hydrolates separation on a laboratory scale (inert gas flow pervaporation system) and semi-technical (vacuum pervaporation system) by means of pervaporation. To create precise matrices for hydrolates before and after pervaporation for each of the separated systems, solid phase microextraction (SPME) technique and the gas chromatography-mass spectrometry (GC-MS) was applied...

INTRODUCTION: The pectoralis major flap is a reconstructive option to consider in the treatment of pharyngocutaneous fistula after a total laryngectomy. There are not large studies assessing variables related to pharyngocutaneous fistula recurrence after removal of the larynx. Our objectives were to review the results obtained with this type of treatment when pharyngocutaneous fistula appears in laryngectomized patients, and to evaluate variables related to the results. METHODS: We retrospectively reviewed our results using either a myocutaneous or fasciomuscular pectoralis major flap to repair pharyngocutaneous fistula in 50 patients...

Aim: The pathology of heart failure is characterized by poorly contracting and dilated ventricles. At the cellular level, this is associated with lengthening of individual cardiomyocytes and loss of sarcomeres. While it is known that the transcription factor myocyte enhancer factor -2 (MEF2) is involved in this cardiomyocyte remodeling, the underlying mechanism remains to be elucidated. Here, we aim to mechanistically link MEF2 target genes with loss of sarcomeres during cardiomyocyte remodeling...

Osteogenesis Imperfecta (OI) is a condition of bone fragility and can present with early onset scoliosis that can cause respiratory complications in later life. The fear of instrumenting the spine in OI is the possibility of fracture either on primary insertion or subsequent lengthening. Magnetically controlled growing rods were inserted to control a scoliosis in a 6-year old with OI type IV. Fixation was obtained using pedicle screws proximally and distally with sublaminar bands around the ribs proximally...

BACKGROUND: Bonding of orthodontic brackets to teeth is important to enable effective and efficient treatment with fixed appliances. The problem is bracket failure during treatment which increases operator chairside time and lengthens treatment time. A prolonged treatment is likely to increase the oral health risks of orthodontic treatment with fixed appliances one of which is irreversible enamel decalcification. This is an update of the Cochrane Review first published in 2003. A new full search was conducted on 26 September 2017 but no new studies were identified...

Background: Understanding the abundance of adverse environmental conditions e.g. frost, drought, and heat during critical crop growth stages, which are assumed to be altered by climate change, is crucial for an accurate risk assessment for cropping systems. While a lengthening of the vegetation period may be beneficial, higher frequencies of heat or frost events and drought spells are generally regarded as harmful. The objective of the present study was to quantify shifts in maize and wheat phenology and the occurrence of adverse environmental conditions during critical growth stages for four regions located in the North German Plain...

Previously we showed thyroid hormone (T3 ) enhanced β-cell functional maturation through induction of Mafa High levels of T3 have been linked to decreased lifespan in mammals, and low levels to lengthened lifespan, suggesting a relationship between thyroid hormone and aging. Here we show T3 increased p16 Ink4a (a β-cell senescence marker and effector) mRNA in rodent and human β-cells. The kinetics of Mafa and p16 Ink4a induction suggested both genes as targets of thyroid hormone via TH receptor (THR) binding to specific response elements (TRE)...

Speech perception behavioral research suggests that rates of sensory memory decay are dependent on stimulus properties at more than one level (e.g., acoustic level, phonemic level). The neurophysiology of sensory memory decay rate has rarely been examined in the context of speech processing. In a lexical tone study, we showed that long-term memory representation of lexical tone slows the decay rate of sensory memory for these tones. Here, we tested the hypothesis that long-term memory representation of vowels slows the rate of auditory sensory memory decay in a similar way to that of lexical tone...

Dysregulated gene expression is another important contributor in explaining cancer-related phenotypes in addition to mutations. Cellular senescence is a mechanism for the prevention of cancer and thus it is important to understand the regulation of gene expression in senescence due to its potential in anti-cancer therapy. Here, we found that CDC73, which encodes the cell division cycle 73 and acts as a tumor suppressor, was unexpectedly up-regulated in several cancer types but down-regulated in a variety of senescent cells...

The origin of the anomeric effect has been reexamined in a coordinated experimental and computational investigation. The results of these studies implicate a number of different, but correlated, interactions that in the aggregate are responsible for the anomeric effect. No single factor is uniquely responsible for the axial preference of a substituent that is the hallmark of the anomeric effect. A CH...G non-bonded attraction between a polar axial substituent (G) and the syn-aial hydrogen(s) i the heterocycle has been demonstrated experimentally...

Background Residual forefoot supination after correcting the hindfoot in stage IIb adult-acquired flatfoot deformity can be addressed with a dorsal opening wedge medial cuneiform (Cotton) osteotomy. The amount of correction is generally judged clinically, and there currently are no preoperative guides that can predict the size of graft needed. The aim of this study was to evaluate the correlation between patient and operative factors and the correction achieved with the Cotton osteotomy. METHODS: Seventy-nine feet in 74 patients undergoing Cotton osteotomy as part of flatfoot reconstruction were reviewed retrospectively...

BACKGROUND: Medial epicanthoplasty is a common aesthetic surgery in Asia to remove the epicanthal fold. With increasing use of this surgery, unsatisfactory results have grown. Several methods have been developed to correct it. However, there are limitations in restoration if the patient has a severe scar or does not have enough skin for reconstruction. By aggressively removing scar tissue, the authors present a better reverse redraping epicanthoplasty. METHODS: The procedure was performed on 512 patients who had complications of medial epicanthoplasty from May 2011 to October 2015...

Producing microchannels with diameters between 10 and 20 μm and with lengths in the tens of centimeters is reported. The method can be modified to obtain diameters as narrow as 350 nm. Length-to-diameter aspect ratios that surpass 104 can be produced for a fraction of current production costs. The controllable channel is produced by applying a flame to the narrow end of a commercial pipette that is made from a soda-lime silicate. In combination with a pulling mechanism, applying heat to the composite material lengthens the pipette in a highly uniform way...

Megan J Crowhurst
Lengthening and creaky voice are associated with prosodic finality in English. Listeners can use lengthening to identify both utterance-internal and final prosodic phrase boundaries and can use creak to locate utterance endings. Less is known about listeners' use of creak to locate internal prosodic boundaries and the relative importance assigned to duration and creak when both are present. Participants in two experiments segmented structurally ambiguous sentences in which duration and creak were manipulated to signal prosodic boundaries...
