Dacron Graft Encased Modified Ross Operation
No full textThe pulmonary autograft operation was introduced by Donald Ross in 1967. Since then, the Ross operation has become a viable and durable option for aortic valve replacement in both the pediatric and adult populations (1). Pulmonary autograft dilatation is one of the complications noted in the adult population. Because of this, the Ross operation is showing a declining trend in this adult population. To prevent this complication, Ross Ungerleider came up with a simple and reproducible modification by adding a Dacron tube graft over the pulmonary autograft, and found no pulmonary autograft dilatation in 30 patients over the period of four years (2).The concerns raised with the modified Ross procedure are that the Dacron tube graft is a cylindrical graft and the sinus portion of the autograft is essential for the normal functioning of the leaflets, as studied in valve-sparing aortic root replacement procedures and experimental studies, and the modified Ross procedure does not address and prevent the potential threat to the valve leaflets function in the long term (3). The pseudosinus creation in the Dacron graft is very important to decrease the stress and strain on the leaflets, so that it is closer to normal, as studied by K .Jane Grande-Allen et al (3).Keeping this in mind, the author has made an additional modification to the modified Ross operation by removing the autograft sinuses, which were getting restricted by the cylindrical Dacron graft, and creating a pseudosinus/neosinus in the Dacron graft.With these modifications to the modified Ross operation, the author hopes to take care of the pulmonary autograft dilatation at all three levels:Annular level – The author sutures the autograft to the Dacron graft and then to the aortic annulus, which prevents annular dilatation.Sinuses – By excising the native autograft sinuses, which are being restricted by the Dacron graft, and creating the pseudosinus/neosinus in the Dacron graft, the author hopes to preserve the valve leaflet function.Sinotubular junction – Since the author is fixing the commissures to the Dacron graft and then suturing the Dacron graft to the ascending aorta, the dilatation at the sinotubular junction is nullified.ReferencesRoss DN.

Financial structures and economic development
No full textThe author constructs a model that captures the two-way nature of the relationship between financial and economic development - and allows societies at different levels of economic development and with different policies to choose different financial services. In this model, various types of financial contracts and institutions arise in response to the economic environment. Incentives for financial structures to emerge are generated by liquidity and productivity risk, the costs of gathering information and mobilizing resources, and the costs of financial transactions. The emergence and development of financial arrangements in response to the economic environment can alter investment decisions and per capita growth rates - while the level of per capita income helps determine the types of financial services a particular society chooses to develop and use. The author not only reconciles more empirical regularities than past theoretical studies have done, but highlights the role of public policies on financial activities. Policy has important implications for the rate of economic growth, the level of financial development, and the types of institutions providing financial services. The model also predicts that per capita growth rates should be related to the types of financial services provided by the financial sector. Thus, the most common empirical measure of financial development may not appropriately capture fundamental features of financial development.Economic Theory&Research,Environmental Economics&Policies,Banks&Banking Reform,Financial Intermediation,Governance Indicators
Ross syndrome: a case report
No full textRoss syndrome is a rare partial dysautonomic syndrome of unknown aetiology, characterized by segmental hypo/ anhidrosis associated with Holmes-Adie syndrome (tonic pupil and hypo/areflexia). The hypohydrosis or anhydrosis is patchy initially, later it becomes segmental or diffuse. This is due to affection of postganglionic cholinergic parasympathetic and sympathetic fibers involvement. There are a very few cases (approximately 50) have been reported in the literature since its original description. Author report a 22 years old male with classical features of Ross syndrome
Virion Background and Efficiency of Virion Incorporation Determine Susceptibility of Simian Immunodeficiency Virus Env-Driven Viral Entry to Inhibition by IFITM Proteins
No full textABSTRACT
Interferon-induced transmembrane proteins (IFITMs) can inhibit the cellular entry of several enveloped viruses, including simian immunodeficiency virus (SIV). The blockade of SIV by IFITMs is isolate specific, raising the question of which parameters impact sensitivity to IFITM. We show that the virion context in which SIV-Env is presented and the efficiency of virion incorporation determine Env susceptibility to inhibition by IFITMs. Thus, determinants other than the nature of the envelope protein can impact the IFITM sensitivity of viral entry.
IMPORTANCE
The host cell-encoded IFITM proteins can block viral entry and are an important component of the innate defenses against viral infection. However, the determinants controlling whether a virus is susceptible to blockade by IFITM proteins are incompletely understood. Our study shows that the amount of envelope proteins incorporated into virions as well as the nature of the virion particle itself can impact the sensitivity of viral entry to IFITMs. These results show for the first time that determinants other than the viral envelope protein can impact sensitivity to IFITM and have implications for the interpretation of previously published data on inhibition of viruses by IFITM proteins. Moreover, our findings might help to define the mechanism underlying the antiviral activity of IFITM proteins.Leibniz-Gemeinschaft https://doi.org/10.13039/50110000166
Subsurface mapping of the Ross Island flexural basin, southwest Antarctica
No full text2016 Summer.Includes bibliographical references.Ross Island is a post-Miocene (< 4.6 Ma) volcanic island located in the Ross Sea region of southwest Antarctica. This region of Antarctica borders the western edge of the West Antarctic Rift System, along the Transantarctic Mountain front. Marine and over-ice multi-channel seismic reflection surveys and borehole studies targeting the Ross Sea region over the last 30+ years have been used in this study to develop a seismic stratigraphic model of the development and evolution of the Ross Island flexural basin. Four key stratigraphic horizons were identified and mapped to fully capture the basin-fill, as well as strata lying above and below the flexural basin. From oldest to youngest these horizons are named RIB-m, RIM-g, RIM-b and RIB-r. Time structure, isochron and isochore maps were created for the horizons and the stratigraphic intervals they bound. The seismic stratigraphic record shows the Ross Island flexural moat formation post-dates the main tectonic subsidence phase within the Victoria Land Basin. The maps presented here are the first to fully illustrate the evolution of the Ross Island flexural basin. The maps highlight depositional patterns of two distinct periods of flexural subsidence and basin-filling superimposed on the older N-S trending Victoria Land Basin depocenter. Two units of flexural basin fill, Unit FFI between horizons RIM-g and RIM-b (the oldest flexural basin fill), and Unit FFII between horizons RIM-b and RIB-r (the youngest flexural basin fill) are associated with the two periods of flexural subsidence. Flexural moat subsidence and subsequent filling occurred episodically during periods of active volcanism on the island. Unit FFI is estimated to range from ca. 4 to 2 Ma, corresponding with formation of the Mt. Bird volcanic edifice on Ross Island. Unit FFII ranges in age from ca. 2 to 1 Ma, and is related to Mt. Terror, Mt. Erebus, and Hut Point Peninsula volcanism. The isochore maps suggest the depocenter of the flexural basin during both time intervals was located north of the island, instead of directly beneath the Ross Island topographic load. Factors contributing to the northerly location of the depocenter include i) volcanic loading by McMurdo Volcanic Group subsea volcanic features north of the island, ii) partial compensation of the main Ross Island load by low-density, partially molten rock beneath the island, iii) extensional faulting within the Terror Rift, and iv) seaward-thickening shelf sediments transported from the Ross Ice Shelf. The seismic data show that the onset of filling of the flexural moat around Ross Island coincided with the end of ice grounding events in the area. We infer that this was caused by flexural subsidence of the seafloor to accommodate the Ross Island load
