Portal vein thrombosis is a common complica- tion in cirrhotic patients. When portal vein thrombectomy is not a suitable option, a large collateral vessel can be used f.r allograf. venous inf.ow reconstruction. We describe an unusu- al case of.successf.l portal revascularization using the right gastroepiploic vein. The patient underwent a cadaveric or- thotropic liver transplantation with end-to-end anastomosis of.the portal vein to the right gastroepiploic vein. Six months af.er liver transplantation the patient is well with good liver f.nction. The use of.the right gastroepiploic vein f.r allograf. venous reconstruction is f.asible and saf., with a great advan- tage of.avoiding the need of.venous jump graf..

Channel straightening in a naturally meandering river is a common historical trigger of.channel incision which typically results in stream bank destabilization. Several of.the larger river systems in the upland portion of.the Yazoo River Basin have subjected channelization resulting in prof.und changes in the physical and geomorphological characteristics of.these systems. f.sh were sampled using electroshocking gear and hoop nets to evaluate the impact of.stream bank destabilization and loss of.habitat heterogeneity resulting f.om channelization on f.sh communities. While distinct dif.erences in the f.sh communities were evident, only the Skuna appeared to have characteristics of.a damaged system. More than 95% of.the biomass was comprised of.species reaching an adult length of.less than 300 mm. The lotic omnivorous f.shes that dominated the biomass f.om Skuna are of.en associated with smaller streams rather than rivers. f.rthermore, 72% of.the catch consisted of.f.sh pref.rring littoral zone habitats. The shallow depth and lack of.woody debris in Skuna provided a selective advantage f.r smaller species of.f.sh that could use shoreline habitats as protection f.om the current. Based on results f.om the Skuna River, channel straightening that leads to channel incision, bank f.ilure and over widening provide habitats too shallow to support a community of.f.shes typical of.northern Mississippi riverine system. This inf.rmation may be usef.l in making comparison of.damaged riverine ecosystems and assist managers in determining impairment and success in the TMDL （Total Maximum Daily Load） process.

Urof.cial syndrome, known as Ochoa syndrome, is a very rare autosomal recessive disorder described as a clinical setting in which there is an association of.a lower urinary tract and bowel dysf.nction with a typical f.cial expression: the patient seems to be grimacing or crying when attempting to smile. If.the diagnosis and treatment are delayed, the patients might have a poor outcome with continuous upper urinary tract deterioration, which makes the early diagnosis of.this condition of.vital importance. We report a case of.two f.males identical twins, who are, nowadays, 19 years old, which had the Ochoa Syndrome diagnosis made when they were 10 years old, but discontinued medical f.llow up during treatment. They have developed chronic renal f.ilure with hemodialysis need and are in a waiting list f.r kidney transplantation. In this rare disorder, even more unusual in twins and with high risks on progressing with renal f.ilure, a simple attempt to smile may save lives if.the condition is known by doctors such as pediatricians and pediatric urologists. Conclusion: We believe that unknowing this condition is the main explanation f.r this f.ct. Early diagnosis and close f.llow up are the key points to a successf.l outcome.

Polycrystalline Pr2f.17-xMnx（x = 0, 1, and 2）alloys were studied by X-ray dif.raction（XRD）, heat capacity, ac susceptibility, and isothermal magnetization measurements. All the alloys adopt the rhombohedral Th2Zn17-type structure. The Curie temperature increases f.om 283 K at x = 0 to 294 K at x = 1, and then decreases to 285 K at x = 2. The magnetic phase transition at the Curie temperature is a typical second-order paramagnetic–f.rromagnetic transition. f.r an applied f.eld change f.om0 to 5 T, the maximum-△SM f.r Pr2f.17-xMnxalloys with x = 0, 1, and 2 are 5.66, 5.07, and 4.31 J·kg^-1·K^-1,respectively. The ref.igerant capacity（RC） values range f.om 458 to 364 J·kg^-1, which is about 70 %–89 % that of.Gd. The large, near room temperature △SM and RC values,chemical stability, and a high perf.rmance-to-cost ratio make Pr2f.17-xMnxalloys be selectable materials f.r room temperature magnetic ref.igeration applications.

Introduction: Hepatocellular carcinoma is the most common primary neoplasm of.the liver and a signif.cant cause of.mortality in patients with cirrhosis. A retrospective cross-sectional study was perf.rmed to analyze epidemiological aspects related to risk f.ctors, diagnosis, staging and f.rst-line treatment in a closed population. Methods: The medical records of.patients seen between November 1998 and May 2011 were revisited. Results: Of.the 272 patients included in this study, 229 (84.2%) were male and the average age was 57.1 years (standard deviation 10.9 years). The most common etiology was hepatitis C virus inf.ction in 145 (55.1%) patients, with this being the single cause in 88 (33.4%) patients. The largest masses ranged f.om 6 mm to 260 mm in diameter with a mean of.61.4 mm (standard deviation 41.5 mm). Only one mass was f.und in 145 (64.2%) cases, two masses in 26 (11.5%), three masses in 9 (4%) and 46 patients (20.3%) had multif.cal disease. Early stage disease was diagnosed in 47 patients (22.0%), advanced stage in 65 (30.4%) and terminal stage in 32 (14.9%). Hepatocellular carcinoma was f.und by chance in 11%. Diagnosis was by means of.imaging in 175 (68.1%) cases. The level of.alpha-f.toprotein was measured in 209 patients, with 29.2% having levels lower than 20 ng/mL and 34.9% having levels above 400 ng/mL. Specif.c treatment was administered in 236 patients (86.8%) with hepatic chemoembolization in 127 (46.7%) and liver transplantation in 72 (26.5%);of.these 33 (45.8%) received hepatic chemoembolization as a bridge to transplantation. Thirty-f.ur patients (12.5%) received only supportive therapy. Conclusions: Patients are chief.y male and disease involvement generally occurs in the 5th decade of.lif.. Cirrhosis was present in most patients and hepatitis C virus inf.ction was the commonest etiologic agent. Only one imaging examination was required f.r diagnosis in most patients. The measurement of.alpha-f.toprotein levels did not prove to be a good too

The communications development requires interaction between converging heterogeneous technology environment, with quality and continuity of.services to remain competitive. The f.ll implementation of.the f.ture Internet concept implies in the necessity to operate among heterogeneous technology platf.rms with continuity of.QoS (Quality of.Service), what leads to the necessity of.an innovative business model to support it and new technical mechanisms of.vertical handover to ensure the QoS continuity required and expected by f.nal users but, mainly, perceived by them. An innovative business model that requires innovative QoS continuity mechanisms must consider technical and commercial interoperation among many telecommunication services providers, nationally and internationally based. This interaction demands clear rules to be f.llowed by every player along the telecommunication services chain,i.e., it demands a set of.regulation acts to guide them and allow their viability.
