Pheochromocytoma-Induced Atrial Tachycardia Leading to Cardiogenic Shock and Cardiac Arrest: Resolution with Atrioventricular Node Ablation and Pacemaker Placement
Authors: Shawa Hassan , Bajaj Mandeep , Cunningham Glenn R. 
Published: December 2014

Pheochromocytoma should be considered in young patients who have acute cardiac decompensation, even if they have no history of hypertension. Atrioventricular node ablation and pacemaker placement should be considered for stabilizing pheochromocytoma patients with cardiogenic shock due to atrial tachyarrhythmias.
A 38-year-old black woman presented with cardiogenic shock (left ventricular ejection fraction, <0.15) that did not respond to the placement of an intra-aortic balloon pump. A TandemHeart® Percutaneous Ventricular Assist Device was inserted emergently. After atrioventricular node ablation and placement of a temporary pacemaker, the TandemHeart was removed. Computed tomography of the abdomen revealed a pheochromocytoma. After placement of a permanent pacemaker, the patient underwent a right adrenalectomy.
This is, to our knowledge, the first reported case of pheochromocytoma-induced atrial tachyarrhythmia that led to cardiogenic shock and cardiac arrest unresolved by the placement of 2 different ventricular assist devices, but that was completely reversed by radiofrequency ablation of the atrioventricular node and the placement of a temporary pacemaker. We present the patient's clinical, laboratory, and imaging findings, and we review the relevant literature.

Published: December 2014

The brachiocephalic artery is an alternative cannulation site in the repair of ascending aortic lesions that require circulatory arrest. We evaluate the effectiveness and safety of this technique.
Proximal aortic surgery was performed in 32 patients from 2006 through 2012 via brachiocephalic artery cannulation and circulatory arrest. Twenty-four (75%) of the patients were men. The mean age was 48.69 ± 9.43 years (range, 30–68 yr). Twelve had type I dissection, 2 had type II dissection, and 18 had true aneurysms of the ascending aorta. All operations were performed through a median sternotomy. The arterial cannula was inserted through an 8-mm vascular graft anastomosed to the brachiocephalic artery in an end-to-side fashion. In dissections, the distal anastomosis was performed without clamping the aorta. The patients were cooled to 24 °C, and circulatory arrest was established. The brachiocephalic and left carotid arteries were clamped, and antegrade cerebral perfusion was started at a rate of 10 mL/kg/min. Cardiopulmonary bypass was resumed after completion of the distal anastomosis and the initiation of rewarming. The proximal anastomosis was then performed.
None of the patients sustained a major neurologic deficit, but 5 patients experienced transient postoperative agitation (<24 hr). There were 2 early deaths (6.25%), on the 3rd and the 11th postoperative days, both unrelated to the cannulation technique.
Brachiocephalic artery cannulation through a graft can be a safe and effective technique in proximal aortic surgical procedures that require circulatory arrest.
Sholem Aleichem in Weimar Berlin: The Cultural Semiotics of Eastern European Jewish Performances
Authors: Zer-Zion Shelly 
Published: December 2014

AbstractAm 28. April 1928 begann die Gastspielreise des Moskauer jiddischen Theaters GOSET in Berlin mit »200.000«, einer jiddischen Bühnenadaption von Shalom Aleichems Dos Groyse Gevin, die von Berliner Kritikern hochgelobt wurde. 1929 kam Habima zum dritten Mal nach Berlin und war beim lokalen Publikum bereits renommiert. Habimas Repertoire bestand unter anderem aus »Der Schatz«, einer hebräischen Adaption von Shalom Aleichems Di Gold Greber. In Gegensatz zu den Reaktionen auf Habimas vorherige Aufführungen wurde dieses Stück mit Empörung aufgenommen. Dieser Artikel bespricht die polarisierte Rezeption dieser beiden Shalom Aleichem Theateraufführungen in Berlin und untersucht, wie die Spannung zwischen der jiddischen und der hebräischen Shalom Aleichems Aufführung den die deutsch-jüdische Identität betreffenden Diskurs animierte.

Filtration model of plastic flow
Authors: Sarychev Vladimir D. , Nevskii Sergey A. , Cheremushkina Elena V. , Gromov Victor E. , Aifantis Elias C. 
Published: December 2014

AbstractA filtration model for plastic flow based on the idea of a deformed material considered as a two-phase heterogeneous medium has been suggested. In this approach, the wave displacement is regarded as a shock transition in the medium. One of the phases (the excited one) is responsible for system restructuring, and the other phase (the normal one) is unrelated to structural transformations. The plastic wave is the result of the interaction of these two phases. The governing equations for the filtration model are obtained. They include the laws of momentum and mass conservation, as well as the filtration ratio of the phases.
The role of Alk-1 and Alk-5 in the mechanosensing of chondrocytes
Authors: Sanz-Ramos Patricia , Dotor Javier , Izal-Azcárate Iñigo 
Published: December 2014

AbstractWe aim to demonstrate the role of Alk receptors in the response of hydrogel expansion. Chondrocytes from rat knees were cultured onto plastic and hydrogel surfaces. Alk-1 and Alk-5 were overexpressed or silenced and the effects on cells during expansion were tested and confirmed using peptide inhibitors for TGFβ. Overexpression of Alk-5 and silencing of Alk-1 led to a loss of the chondrocyte phenotype, proving that they are key regulators of chondrocyte mechanosensing. An analysis of the gene expression profile during the expansion of these modified cartilage cells in plastic showed a better maintenance of the chondrocyte phenotype, at least during the first passages. These passages were also assayed in a mouse model of intramuscular chondrogenesis. Our findings indicate that these two receptors are important mediators in the response of chondrocytes to changes in the mechanical environment, making them suitable targets for modulating chondrogenesis. Inhibition of TGFβ could also be effective in improving chondrocyte activity in aged or expanded cells that overexpress Alk-1.
Optimization of PCR Conditions for DNA Amplification of Common Buckwheat Using EST Primers
Authors: Joshi Bal K. , Okuno Kazutoshi , Ohsawa Ryo , Hara Takashi 
Published: December 2014

Under optimal conditions the PCR reaction is very efficient; microgram quantities may be synthesized from a single molecule of substrate DNA. DNA of four lines of common buckwheat (Kyusu, Canada, Miyazaki and Botansoba) was used to optimize PCR reaction and cycling program of 26 primers for DNA amplification of common buckwheat. Annealing temperature (Ta), PCR cycle number and MgCl2 concentration were considered optimum if the single clear band was observed. Of the 26 primers Ta of only 10 primers could be optimized. Three primer pairs performed best at Ta of 54°C. The optimum concentration of MgCl2 was found to be 1.5mM for all primer pairs. Similarly the number of PCR cycles was found to be 40 for all 10 primer pairs except for primer pair 57. Optimized PCR conditions were used for subsequent studies such as transferability of EST primers to other Fagopyrum species and construction of linkage map.Nepal Agric. Res. J.

Use of Fertilizers and Lime for Enhancing Productivity of Maize Genotypes in Western Hill of Nepal
Authors: Adhikary Bishnu H. , Karki Krishna B. 
Published: December 2014

Farmers' field experiment was conducted at Outreach sites in Tanahun and Palpa districts of Western Nepal with the objectives of evaluating the effects of fertilizers and agricultural lime on grain production of the local and improved (Manakamana-1) maize varieties during summer season of year 2003 and 2004. Farmer's practice (without fertilizers) and with fertilizer 60: 30: 30 kg (N: P2O5: K2O) per hectare with or without agricultural lime (4 t ha-1), were the treatments in experimental study that was conducted in factorial RCB design with four farmers as replications. The results revealed that response of fertilizers and agricultural lime was observed significant plant growth and kernels production including varieties in both sites of Palpa and Tanahun districts. The highest grain yield of 5.1 t ha-1 was produced by the local variety when the crop was supplied with 60:30:30 kg N, P2O5 and K2O ha-1 along with 4 t ha-1 of agricultural lime in Tanahun. Manakamana-1 variety produced the maximum grain yield (4.45 t ha-1) with the same level of fertilization. The two district mean grain yield result indicated that the highest grain yield of 3.9 t ha-1 was produced when the crop was supplied with 60: 30: 30 kg N, P2O5 and K2O ha-1 with agri-lime. Hence it is suggested that to increase maize productivity in the hills irrespective of the maize variety application of fertilizers (60: 30: 30) with agricultural lime (4 t ha-1) is needed.Nepal Agric.

Identification of Suitable Planting Method for Potato + Maize Intercropping System in the Hill of Eastern Nepal
Authors: Barakoti Tanka P. 
Published: December 2014

Field experiments to identify suitable planting method under potato + maize system in the high hill (2200 m) of eastern Nepal Sindhuwa, Dhankuta, was conducted during 2000 and 2001 seasons for the potato variety Hale and maize variety Ganesh 1. Of the different planting methods tested, significantly the highest yield of potato (15.5 t/ha) was recorded from the alternate row planting followed by recommended practice and flat row planting. Early emergence (by 7-12 days) was in farmers' practice, whereas uniform plants (1-5 scale) observed in flat row and double row planting. Maize did not follow this trend. Double row and farmer's practice favored good ground coverage (80-95%) by potato plants, which attained height from 49.8cm (farmer's practice) to 56.8 cm (flat row). Number of main stems/plant was higher in all treatments, except farmer's practice. Similar trend was followed in tuber numbers. Maturity of crops did not depend on planting methods. Final stand of potato ranged between 46.9 (alternate row) and 68.6 thousand/ha (farmer's practice). Late blight and bacterial wilt infection was higher in the farmers' practice. The height of maize plants was significantly differed between sole cropping (220 cm), which yielded higher followed by alternate row (183 cm) and flat row plantings. Gross income from maize and potato was higher in flat row planting. The data revealed that alternate row and flat row planting methods were superior over the common farmers' practice and the recommended practice, so the identified planting methods were recommended.Nepal Agric.

Pollen and Spikelet Analysis in F1 Rice Hybrids and their Parents
Authors: Joshi Bal K. , Subedi Laxmi P. , Gurung Santa B. , Sharma Ram C. 
Published: December 2014

Pollen analysis can be used to discriminate between different species, identify possible interspecies hybrids, identify restorer and maintainer lines, useful to study genetics of restorer gene, interaction between chromosome and cytoplasm and relationship between parents. Pollen abortion system of male sterility is an important tool in hybrid rice production and spikelet is the major yield components. Nine improved cultivars, six landraces and three wild aborted cytoplasmic-genetic male sterile (CMS) lines were used to analyze pollen and spikelet in F1 rice hybrids and their parents. The frequency of pollen categories and its relationship to spikelet fertility were investigated. Pollen sterility of the F1s was determined by staining pollen grains in 1% potassium iodide-iodine (I-KI) solution. Spikelet fertility was determined by counting the total number of seed set in proportion to the total number of spikelets. Correlation and regression coefficients for some traits were computed. In hybrids, pollen fertility ranged from 0.5 to 82% and spikelet fertility from 0 to 87%. Pollen fertility varied from 28 to 97%, while spikelet fertility from 73 to 91% in pollen parents. The highest and the lowest percentages of pollen fertility were found in Chaite-6 and Chiunde cultivars respectively. Spikelet fertility percentage varied widely among hybrids and many hybrids had lower spikelet fertility percentage than their parents. Therefore, it is of practical importance to understand the causes of high spikelet sterility in hybrids for possible increase in spikelet fertility. Highly significant positive correlation was found between stained round fertile (SRF) pollen and spikelet fertility. The positive value of correlation and regression coefficient on SRF and spikelet fertility were found between F1 and mid parent, and F1 and male parent. High fertility of cross may be due to the presence of a wide compatibility gene or restorer genes in the cultivar. Lower pollen and spikelet fertility of the crosses was attributed to effect of the genetic background of the tester parent. Nepal Agric. Res. J.

Comparison of Astigmatic Correction After Femtosecond Lenticule Extraction and Wavefront-Guided LASIK for Myopic Astigmatism
Authors: Ali Mohamed A. , Kobashi Hidenaga , Kamiya Kazutaka , Igarashi Akihito , Miyake Toshiyuki , Elewa Mohamed Ehab M. , Komatsu Mari , Shimizu Kimiya 
Published: December 2014

PURPOSE:
To compare postoperative astigmatic correction between femtosecond lenticule extraction (FLEx) and wavefront-guided LASIK in eyes with myopic astigmatism.

METHODS:
Fifty-eight eyes of 41 patients undergoing FLEx and 49 eyes of 29 patients undergoing wavefront-guided LASIK to correct myopic astigmatism were examined. Visual acuity, cylindrical refraction, predictability of the astigmatic correction, and astigmatic vector components were compared between groups 6 months after surgery.

RESULTS:

There was no statistically significant difference in manifest cylindrical refraction (
P
= .08) or percentage of eyes within ±0.50 diopter (D) of its refraction (
P
= .11) between the surgical procedures. The index of success in FLEx was statistically significantly better than that of wavefront-guided LASIK (
P
= .02), although there was no significant difference between the groups in other indices (eg, surgically induced astigmatism, target-induced astigmatism, astigmatic correction index, angle of error, difference vector, and flattening index). Subgroup analysis showed that FLEx had a better index of success (
P
= .02) and difference vector (
P
= .04) than wavefront-guided LASIK in the low cylinder subgroup; the angle of error in FLEx was significantly smaller than that of wavefront-guided LASIK in the moderate cylinder subgroup (
P
= .03).

CONCLUSIONS:
Both FLEx and wavefront-guided LASIK worked well for the correction of myopic astigmatism by the 6-month follow-up visit. Although FLEx had a better index of success than wavefront-guided LASIK when using vector analysis, it appears equivalent to wavefront-guided LASIK in terms of visual acuity and the correction of astigmatism.

Authors: Yu Charles Q. , Manche Edward E. 
Published: December 2014

PURPOSE:
To prospectively compare the achieved thickness and consistency of LASIK flaps created with a 60- and 150-kHz femtosecond laser.

METHODS:
One hundred twenty eyes of 60 patients with myopia were treated with LASIK. One eye had flap created by the Intralase FS 60-kHz femtosecond laser (Abbott Medical Optics, Abbott Park, IL) and the fellow eye was treated with the IntraLase iFS 150-kHz femtosecond laser (Abbott Medical Optics). Eyes were randomized according to ocular dominance. Flap morphology and measurements were taken with anterior segment optical coherence tomography (AS-OCT) at the 1-month postoperative visit.

RESULTS:

AS-OCT showed similar regular planar morphologies in both groups. The mean thickness of the flaps in the FS 60 group was significantly higher than that of the iFS 150 group (105.4 ± 3.9
μ
m vs 103.9 ± 4.8
μ
m,
P
= .009). The mean deviation from targeted flap thickness was not significantly different between the two groups.

CONCLUSIONS:
The Intralase iFS 150-kHz femtosecond laser creates flaps of similar thickness and uniformity to the Intralase FS 60-kHz femtosecond laser.

Corporations are People Too
Authors: White Robert 
Published: December 2014

Abstract
This article applies Ayn Rand's insights in metaphysics and epistemology to the question What is a corporation? Historically, there have been three main answers: the fictional entity theory, the aggregate theory, and the real entity theory. Drawing principally upon Rand's discussion of the nature of entities in her epistemology workshops, this article proposes a fourth possibility. The preceding theories assume that if a corporation is an entity it must exist as a separate entity. The theory defended in this article challenges this assumption, and considers the implications for the moral and political status of corporations.
A Latter-Day Jacobin with a Lot of Data
Authors: Gissurarson Hannes H. 
Published: December 2014

Abstract
Piketty underestimates the disposable income of the poor, while he overestimates the corresponding income of the rich, for systemic reasons. Recently, global income inequality has gone down. Piketty's belief that in the long run the rate of return for capital will surpass economic growth is not plausible. Capital tends to disperse, and the creative powers of capitalism, leading to economic growth, should not be underestimated. Piketty is worried about the superrich, but he should rather be worried about the increased power of government. What will happen if the rich cease to create wealth, as described in Atlas Shrugged?
Protective and pathological roles of tissue factor in the heart
Authors: Bode M. F. , Mackman N. 
Published: December 2014

SummaryTissue factor (TF) is expressed in the heart where it is required for haemostasis. High levels of TF are also expressed in atherosclerotic plaques and likely contribute to atherothrombosis after plaque rupture. Indeed, risk factors for atherothrombosis, such as diabetes, hypercholesterolaemia, smoking and hypertension, are associated with increased TF expression in circulating monocytes, microparticles and plasma. Several therapies that reduce atherothrombosis, such as statins, ACE inhibitors, beta-blockers and anti-platelet drugs, are associated with reduced TF expression. In addition to its haemostatic and pro-thrombotic functions, the TF : FVIIa complex and downstream coagulation proteases activate cells by cleavage of protease-activated receptors (PARs). In mice, deficiencies in either PAR-1 or PAR-2 reduce cardiac remodelling and heart failure after ischaemia-reperfusion injury. This suggests that inhibition of coagulation proteases and PARs may be protective in heart attack patients. In contrast, the TF/thrombin/ PAR-1 pathway is beneficial in a mouse model of Coxsackievirus B3-induced viral myocarditis. We found that stimulation of PAR-1 increases the innate immune response by enhancing TLR3-dependent IFN-_ expression. Therefore, inhibition of the TF/thrombin/PAR-1 pathway in patients with viral myocarditis could have detrimental effects. Conclusion: The TF : FVIIa complex has both protective and pathological roles in the heart.
