Effect of accelerative forces on avian embryogenesis
Authors: Besch E. L. , Smith A. H. , Goren S. 
Published: December 2017

Fertile avian eggs from the domestic fowl and the Japan quail showed a measurable loss of weight and a reduction atchability when exposed to varying intensities of centrifugal force for 10 min. Both of these effects are proportional to intensity of the applied force. Coturnix (Japanese quail) chicks hatched from eggs exposed to centrifugal forces prior to incubation displayed no growth rate differences from those chicks from control eggs. Impact force necessary to cause failure of embryo development is in excess of shell failure stress. The effect of subacute acceleration and impact deceleration is not manifested in the same manner in embryonated as in fertile eggs. mechanical force; impact deceleration; centrifugal force; avian eggs; hatchability; embryo development Submitted on December 31, 1964
Effect of exercise on the cerebral circulation and metabolism
Authors: Zobl Eldred G. , Talmers Frederick N. , Christensen Raymond C. , Baer Lesem J. 
Published: December 2017

Cerebral hemodynamics and metabolism were studied in 13 normal patients and 14 hypertensive patients at rest and during vigorous physical exercise. Cerebral blood flow was determined by the nitrous oxide method. The cerebral vascular resistance in normal and hypertensive patients remained remarkably constant during exercise despite a marked reduction in total peripheral resistance. Cerebral blood flow was relatively unaffected by the marked increase in cardiac output and the cerebral metabolism did not share in the increased total body metabolism. During vigorous physical exercise the brain behaved as a steady-state organ. cerebral resistance; cerebral blood flow; cerebral oxygen consumption; exercise Submitted on February 4, 1965
Water flux across the rat jejunum and ileum
Authors: Berger Eugene Y. , Pecikyan Rene , Kanzaki Grace 
Published: December 2017

The flux of tritiated water from mucosa to serosa and from serosa to mucosa was measured across the rat ileum and rat jejunum in an in vitro perfusion system. The rate at which the specific activity of tritiated water decreased with time was an almost linear logarithmic function in the ileal serosal bath, whereas under identical conditions the rate of decrease was plainly curvilinear in the jejunal serosal bath. In comparing the first 40 min to the subsequent 60–100 min, the flux from mucosa to serosa across the ileum increased by 6.7 ± 5.6% in 12 comparisons, while the flux across the jejunum decreased by 21.O ± 9.9% in 7 comparisons. These observations illustrate the pitfall in determining flux rates based on a single determination at the beginning and end of an observation period. They illustrate the necessity of setting experimental conditions to be able to obtain intervening determinations to have some assurance that flux has not changed during the period of measurement. tritiated water flux

Published: December 2017

Background
Pericardial effusions can be caused by a variety of disorders. The frequency of the underlying diseases varies with patient population; therefore, previously reported series are not necessarily representative of other populations. Our purpose was to examine the etiology of pericardial effusions and the survival of patients requiring pericardiocentesis at a tertiary center.

Methods and Results

We performed a retrospective observational study of 269 consecutive patients who underwent percutaneous pericardiocentesis at our university hospital between 2006 and 2016 and had prospective follow‐up for up to 10 years. The most frequent etiologies were idiopathic (26%), malignancy (25%), and iatrogenicity (20%), whereas bacterial causes were very rare. The most frequent malignancies originated from the lung (53%) or breast (18%). A new cancer was diagnosed with malignant pericardial effusion as the presenting complaint for 9% of patients, whereas the pericardium was the first metastatic site of a known malignancy in 4% of patients. Survival was significantly poorer in malignancy‐related versus non–malignancy‐related effusions (
P
<0.001) and in cytology‐positive versus cytology‐negative effusions in the overall cohort (
P
<0.001). Among cancer‐only patients, however, there was no significant difference in long‐term survival between cytology‐positive and ‐negative effusions.

Conclusions
In this contemporary tertiary‐center cohort, pericardial effusions often represent the primary instance of a new malignancy, underscoring the importance of cytological analyses of noniatrogenic effusions in patients without known cancer, as survival is significantly worse. In cancer patients, however, the presence of pericardial malignant cytology does not appear to affect outcome significantly.
Advice for festive drinkers
Authors: Hadis Mohammed A , Palin William M , Perryer D Giles , Burke FJ Trevor 
Published: December 2017

Abstract: The incidence of tooth wear is rising, worldwide, with extrinsic and intrinsic erosion being involved in many cases. A variety of drinks have been considered to be implicated, for example, fresh fruit juices, carbonated beverages, alcoholic drinks and energy/sports drinks. However, there are a number of beverages which do not appear to have been tested, such as sparkling wines and various types of champagne and sparkling fruit juice, these being drinks that are typically consumed at times of celebration such as religious festivals, birthdays, etc. It is therefore the purpose of this paper to test the acidity of these festive drinks and to provide advice to consumers thereof. CPD/Clinical Relevance: Some sparkling alcoholic and non-alcoholic drinks may be erosive to patients' teeth, depending upon the volume consumed.

Published: December 2017

<p class="Abstract">Frankenia hirsuta is widely located in Turkey, but the antimicrobial potential and biochemical composition analysis of it weren’t determined yet. By using the disk diffusion method, the susceptibility of 17 bacteria and 1 fungi were analyzed, which included Bacillus, Candida, Enterobacter, Enterococcus, Esche-richia, Klebsiella, Listeria, Pseudomonas, Salmonella and Staphylococcus genera. 0.8, 1.5 and 3.1 mg of samples were prepared by using absolute ethanol. The bioactive composition of the plant extract was determined by gas chromato-graphy-mass spectroscopy, and National Institute of Standards and Techno-logy library was used for the mass spectra analysis. The results showed that F. hirsuta had antimicrobial activity against all of the studied micro-organisms except E. aerogenes and E. coli. Several active metabolites were identified, but some composition of this sample didn’t match with the library. These results are the first report for the antimicrobial potential and biochemical composition of F. hirsuta.</p><p class="Abstract"><strong>Video Clip of Methodology</strong>:</p><p class="Abstract">3 min 36 sec: <a href="https://www.youtube.com/v/YeKtYxtaa6c">Full Screen</a> <a href="https://www.youtube.com/watch?v=YeKtYxtaa6c">Alternate</a></p>
París, Buenos Aires, México, Milán, Madrid…Migraciones, tránsitos y convergencias para un mapa del arte moderno
Authors: Wechsler Diana B. 
Published: December 2017

El “gran relato” del arte moderno coloca a París como centro indiscutido. Sobre esta narrativa podemos imaginar gráficamente una cantidad de flechas en dirección a ese centro que proceden de distintos sitios de Europa, América, Oriente. También, esas mismas flechas, aparecerán en la dirección contraria. Así, París se presenta como centro de atracción e irradiación a la vez. Sin embargo, si bien esto forma parte sin dudas de aquel proceso moderno, no son menos esas otras flechas que amplían la interacción entre París y el resto de las metrópolis modernas de Europa y América (en busca de acotar el campo de este ensayo). Ensayos curatoriales como París-Berlín o París-Moscú buscaron trazar algunas de estas direcciones ; Territorios de diálogo también ensayó otra cartografía, pero dado el recorte elegido París quedaba lejana. Es por eso que en este artículo elijo retomar el trazado de estas cartografías recentrando a París para reponer con ella, y en la interacción así como con las señales convergentes de otras metrópolis, otros aspectos de la dinámica moderna en las décadas del veinte y treinta del siglo pasado en donde se recupera además la noción de internacionalización acuñada justamente en estos tiempos.

On the Far‐Zone Electromagnetic Field of a Horizontal Electric Dipole Over an Imperfectly Conducting Half‐Space With Extensions to Plasmonics
Authors: Michalski Krzysztof A. , Lin Hung‐I 
Published: December 2017

AbstractSecond‐order asymptotic formulas for the electromagnetic fields of a horizontal electric dipole over an imperfectly conducting half‐space are derived using the modified saddle‐point method. Application examples are presented for ordinary and plasmonic media, and the accuracy of the new formulation is assessed by comparisons with two alternative state‐of‐the‐art theories and with the rigorous results of numerical integration.
Palladium‐Catalyzed Synthesis of (E)‐5‐(3‐Aminoallyl)‐Uridine‐5′‐O‐Triphosphates
Authors: Shanmugasundaram Muthian , Senthilvelan Annamalai , Kore Anilkumar R. 
Published: December 2017

AbstractThis unit describes a simple, reliable, and efficient chemical method for the synthesis of 5‐(3‐aminoallyl)‐2′‐deoxyuridine‐5′‐O‐triphosphate (AA‐dUTP) and 5‐(3‐aminoallyl)‐uridine‐5′‐O‐triphosphate (AA‐UTP), starting from the corresponding nucleoside triphosphate. The presented strategy involves regioselective iodination of nucleoside triphosphate using N‐iodosuccinimide followed by the palladium‐catalyzed Heck coupling with allylamine to provide the corresponding (E)‐5‐aminoallyl‐uridine‐5′‐O‐triphosphate in good yields. It is noteworthy that the protocol not only provides a high‐purity product but also eliminates the use of toxic mercuric reagents. © 2017 by John Wiley & Sons, Inc.
Synthesis of Bipartite Tetracysteine PNA Probes for DNA In Situ Fluorescent Labeling
Authors: Fang Ge‐min , Seitz Oliver 
Published: December 2017

Abstract“Label‐free” fluorescent probes that avoid additional steps or building blocks for conjugation of fluorescent dyes with oligonucleotides can significantly reduce the time and cost of parallel bioanalysis of a large number of nucleic acid samples. A method for the synthesis of “label‐free” bicysteine‐modified PNA probes using solid‐phase synthesis and procedures for sequence‐specific DNA in situ fluorescent labeling is described here. The concept is based on the adjacent alignment of two bicysteine‐modified peptide nucleic acids on a DNA target to form a structurally optimized bipartite tetracysteine motif, which induces a sequence‐specific fluorogenic reaction with commercially available biarsenic dyes, even in complex media such as cell lysate. This unit will help researchers to quickly synthesize bipartite tetracysteine PNA probes and carry out low‐cost DNA in situ fluorescent labeling experiments. © 2017 by John Wiley & Sons, Inc.
Practical Synthesis of 4′‐Thioribonucleosides from L‐Arabinose via Novel Reductive Ring‐Contraction Reaction and Pummerer‐Type Thioglycosylation

Published: December 2017

AbstractThe detailed practical synthesis of 4′‐thionucleosides starting from L‐arabinose is described here. 1,4‐Anhydro‐2,3‐O‐isopropylidene‐4‐thioribitol, which is the key intermediate for the synthesis of 4′‐thionucleosides, is obtained from L‐arabinose in several steps, including a novel reductive ring‐contraction reaction. After oxidation of the key intermediate, the sulfoxide is subjected to Pummerer‐type thioglycosylation in the presence of persilylated nucleobases to obtain the 4′‐thioribonucleosides in good yield and β‐selectively. © 2017 by John Wiley & Sons, Inc.
High‐Shear‐Imparted Tunable Fluorescence in Polyethylenimines
Authors: Luo Xuan , Al‐Antaki Ahmed Hussein Mohammed , Pye Scott , Meech Robyn , Zhang Wei , Raston Colin L. 
Published: December 2017

AbstractIn general, fluorescent polyethylenimine (PEI) nanoparticles absorb primarily UV light, with the fluorophores typically having extended conjugated structures. In this work, PEI nanoparticles of circa 10 nm in diameter, devoid of such structural features and with tunable fluorescence, were generated in a microfluidic platform. Tunability of the fluorescence was achieved by varying the flow rate of liquid entering the rapidly rotating tube in a vortex fluidic device (VFD), without the need for additional reagents. Chemical incorporation of amide functional groups triggered enhanced fluorescence intensity and auto‐fluorescence over a wide range, and the resulting nanoparticles showed significantly reduced cytotoxicity compared to as‐received polymers.
The effect of visual feedback of body parts on pain perception: A systematic review of clinical and experimental studies
Authors: Wittkopf P.G. , Lloyd D.M. , Johnson M.I. 
Published: December 2017

AbstractThe aim of this systematic review was to evaluate the effect of visual feedback techniques on pain perception by analysing the effect of normal‐sized, magnified or minified visual feedback of body parts on clinical and experimentally‐induced pain. Databases searched: Medline, Embase, PsychInfo, PEDro, CINAHL, CENTRAL and OpenSIGLE. Studies investigating pain patients and pain‐free participants exposed to experimentally‐induced pain were analysed separately. Risk of bias was assessed and data were meta‐analysed. Thirty four studies were included. A meta‐analysis of clinical data favoured mirror visual feedback (six trials; mean difference = −13.06 mm; 95% CI = −23.97, −2.16). Subgroup analysis favoured mirror visual feedback when used as a course of treatment (three trials; mean difference = −12.76 mm; 95% CI = −24.11, −1.40) and when used for complex regional pain syndrome for complex regional pain syndrome (three trials; standard mean difference = −1.44; 95% CI = −1.88, −0.99). There is insufficient evidence to determine differences between normal‐sized view and a size‐distorted view of the limb. Mirror visual feedback was not superior to object view or direct view of the hand for reducing experimental pain in pain‐free participants. There were inconsistencies in study findings comparing normal‐sized reflection of a body part and a reflection of an object, or a magnified or minified reflection. There is tentative evidence that mirror visual feedback can alleviate pain when delivered as a course of treatment, and for patients with complex regional pain syndrome. It was not possible to determine whether normal‐sized, magnified or minified visual feedback of body parts affects pain perception because of contradictory findings in primary studies.SignificanceIt was not possible to determine whether normal‐sized, magnified or minified visual feedback of body parts affected pain perception in clinical or experimental settings because of contradictory findings in primary studies. This emphasizes the need for higher quality studies.
Non‐alcoholic fatty pancreas disease as a risk factor for pancreatic cancer based on endoscopic ultrasound examination among pancreatic cancer patients: A single‐center experience
Authors: Lesmana Cosmas R A , Gani Rino A , Lesmana Laurentius A 
Published: December 2017

Background and AimNon‐alcoholic fatty pancreas disease (NAFPD) is a disease that ranges from simple steatosis and can further lead to chronic pancreatitis and possible pancreatic cancer development. Its exact pathogenesis and impact on clinical practice are still largely unknown. Pancreatic cancer is still the most lethal malignancy in the world. Studies about the relationship between NAFPD and pancreatic cancer are still lacking. This study aims to find the possible role of endoscopic ultrasound (EUS) examination as a screening tool in NAFPD patients based on EUS examination among pancreatic cancer patients.MethodsEUS hospital data were collected within a 2‐year period, and all patients who underwent EUS procedures were analyzed. Pancreatic malignancy was diagnosed based on imaging and tumor markers and cytopathology using the endoscopic ultrasound fine needle aspiration (EUS‐FNA) procedure. Patients with pre‐existing pancreatic diseases, significant alcohol consumption, or other primary cancer with metastasis to the pancreas were excluded. Statistical analysis was performed using SPSS version 23.0.ResultsIn total, 162 patients (75 females and 87 males) were recruited for database analysis.^ Pancreatic malignancy was found in 43 (26.5%) patients, whereas fatty pancreas was found in 53 (32.7%) patients, and this was commonly found among pancreatic cancer patients.^ Based on logistic regression analysis, factors such as age, gender, diabetes, and chronic pancreatitis were not found to be significant risk factors for pancreatic malignancy where fatty pancreas is the only significant risk factor for pancreatic cancer (odds ratio: 18.027 [95% CI: 7.288–44.588]).ConclusionPrevalence of NAFPD among pancreatic cancer patients is high. Future studies can be conducted to show whether EUS can be considered a screening tool for the early detection of pancreatic malignancy in NAFPD patients; a cohort prospective study might also be needed to show clear causality between fatty pancreas and pancreatic cancer.

AbstractIncreasing anthropogenic disturbances have driven declines of many coral‐dominated reef states, threatening critical ecosystem functions such as reef‐scale calcification and accretion. Few studies have investigated the effect of coral bleaching on reef‐scale calcification. In this study, we monitored bay‐wide alkalinity anomalies in Kāne'ohe Bay, Hawai'i along an inshore‐offshore transect as a proxy for net calcification during the 2015 coral bleaching event and following recovery over a full seasonal cycle. We observed no net calcification in October 2015 during the bleaching event followed by a recovery to significant, positive net calcification rates in June 2016, November 2016, and February 2017 across a range of seawater temperatures and hydrodynamic conditions. Post‐bleaching net calcification rates were not significantly different between survey dates and agreed with the range of pre‐bleaching net calcification rates from a previous study suggesting that net calcification in Kāne'ohe Bay had fully recovered following the 2015 bleaching event.
