Capital inflow reversals, banking stability, and prudential regulation in Central and Eastern Europe
The authors show that capital inflows into the countries of Central and Eastern Europe (CEE)--inflows that are mainly private, debt-driven, and increasingly supplied by banks on a shortening maturity--are especially vulnerable to reversals. They show that the region's banking systems are disproportionately exposed to those reversals, and absorb the lion's share of bank-supplied inflows. They analyze the main links through which external finance turbulence is transmitted to the domestic banking industry, especially during the transition. Mechanisms for prudential regulation are in place in the region--and largely mimic the standards directed by the European Union--but the authors argue that these standards are insufficient for CEE countries. They base their arguments not on actual enforcement (a genuine concern) but on the fact that EU banking directives were designed for more stable economies and for banking systems less vulnerable to reversals in capital inflows. A strong case can be made, for CEE countries to overshoot those directives, at least until the transition is complete.Banks&Banking Reform,Payment Systems&Infrastructure,Financial Intermediation,International Terrorism&Counterterrorism,Financial Crisis Management&Restructuring,Banks&Banking Reform,Financial Intermediation,Economic Theory&Research,Settlement of Investment Disputes,Financial Crisis Management&Restructuring
COVID-19 and pulmonary rehabilitation: preparing for phase three.
Considering the expected high burden of respiratory, physical and psychological impairment following the acute phase of COVID-19, a huge number of patients should be referred early to a rehabilitation program. Pulmonary rehabilitation is an evidence-based, well recognized and widely accepted and available to cover these needs
Equivalent birational embeddings II: divisors
Two divisors in are said to be Cremona equivalent if there is a
Cremona modification sending one to the other. We produce infinitely many non
equivalent divisorial embeddings of any variety of dimension at most 14. Then
we study the special case of plane curves and rational hypersurfaces. For the
latter we characterise surfaces Cremona equivalent to a plane.Comment: v2 Exposition improved, thanks to referee, unconditional

Musculoskeletal syndrome treated with global postural re-education in double-redo lung transplantation: a case report with an 8-month follow-up
Postoperative pain and persisting fatigue represent critical concerns for patients receiving lung transplantation. The purpose of this study was to illustrate the trajectory of symptoms in a patient who presented with a posttransplant musculoskeletal syndrome after double redo-lung transplantation and attended therapeutic sessions of global postural re-education during the symptomatic phase. A 32-year-old woman with interstitial lung disease underwent double lung transplantation. At 23 months, functional parameters deteriorated, and the patient was placed on the active list for a second double-lung transplantation. Twenty months after re-transplantation, the patient reported continuous thoracic-lumbar musculoskeletal pain exacerbated by moving or performing the standard motor activities. Lower body flexibility improved during the observation period changed from -10 cm to 0 cm at the Chair Sitand- Reach Test. Leg strength improved as well, and the patient was able to perform more repetitions at the Squat Test, improving from 14 to 39. Pain intensity changed from 7 to 4 on a numerical rating scale. We observed that outcomes strictly related to treatment, with lower body flexibility, pain intensity, and physical function improving over time. As a result global postural re-education proved to be effective in this patient
Insulin-secreting pituitary GH3 cells : a potential beta-cell surrogate for diabetes cell therapy
In a companion article, we describe the engineering and characterization of pituitary GH3 cell clones stably transfected with a furin-cleavable human insulin cDNA (InsGH3 cells). This article describes the performance of InsGH3 (clones 1 and 7) cell grafts into streptozotocin (STZ)-induced diabetic nude mice. Subcutaneous implantation of 2
7 106 InsGH3 cells resulted in the progressive reversal of hyperglycemia and diabetic symptoms, even though the progressive growth of the transplanted cells (clone 7) eventually led to glycemic levels below the normal mouse range. Proinsulin transgene expression was maintained in harvested InsGH3 grafts that, conversely, lose the expression of the prolactin (PRL) gene. Elevated concentrations of circulating mature human insulin were detected in graft recipients, demonstrating that proinsulin processing by InsGH3 cells did occur in vivo. Histologic analysis showed that transplanted InsGH3 grew in forms of encapsulated tumors composed of cells with small cytoplasms weakly stained for the presence of insulin. Conversely, intense insulin immunoreactivity was detected in graft-draining venules. Compared to pancreatic \u3b2TC3 cells, InsGH3 cells showed in vitro a higher rate of replication, an elevate resistance to apoptosis induced by serum deprivation and proinflammatory cytokines and significantly higher antiapoptotic Bcl-2 protein levels. Moreover, InsGH3 cells were resistant to the streptozotocin toxicity that, in contrast, reduced \u3b2TC3 cell viability to 50-60% of controls. In conclusion, proinsulin gene expression and mature insulin secretion persisted in transplanted InsGH3 cells that reversed hyperglycemia in vivo. InsGH3 cells might represent a potential \u3b2-cell surrogate because they are more resistant than pancreatic \u3b2 cells to different apoptotic insults and might therefore be particularly suitable for encapsulation
Proinflammatory Cytokines Activate the Intrinsic Apoptotic Pathway in β-Cells
OBJECTIVE:Proinflammatory cytokines are cytotoxic to beta-cells and have been implicated in the pathogenesis of type 1 diabetes and islet graft failure. The importance of the intrinsic mitochondrial apoptotic pathway in cytokine-induced beta-cell death is unclear. Here, cytokine activation of the intrinsic apoptotic pathway and the role of the two proapoptotic Bcl-2 proteins, Bad and Bax, were examined in beta-cells.RESEARCH DESIGN AND METHODS:Human and rat islets and INS-1 cells were exposed to a combination of proinflammatory cytokines (interleukin-1beta, interferon-gamma, and/or tumor necrosis factor-alpha). Activation of Bad was determined by Ser136 dephosphorylation, mitochondrial stress by changes in mitochondrial metabolic activity and cytochrome c release, downstream apoptotic signaling by activation of caspase-9 and -3, and DNA fragmentation. The inhibitors FK506 and V5 were used to investigate the role of Bad and Bax activation, respectively. [...
Stage 4 neuroblastoma: sequential hemi-body irradiation or high-dose chemotherapy plus autologous haemopoietic stem cell transplantation to consolidate primary treatment
The aim of the present study was to evaluate the effectiveness of two consecutive nonrandomised treatment programs applied between 1989 and 1999 at the Istituto Nazionale Tumori of Milan in an unselected cohort of 59 children over the age of one with stage 4 neuroblastoma. Both treatment programs consisted of two phases, the induction of the remission phase and the consolidation phase. The induction of the remission phase consisted of intensive chemotherapy, and remained the same throughout the study period. The consolidation phase consisted of sequential hemi-body irradiation (HBI) (10 Gy per session, 6 weeks apart) in the first period (1988–June 1994) and sequential high-dose cyclophosphamide, etoposide, mitoxantrone+L-PAM and autologous haemopoietic stem cell transplantation in the second (July 1994–1999). Intention-to-treat analysis revealed a significantly better outcome for patients treated with the second program, the 5-year event-free survival probability being 0.12 for program 1 and 0.31 for program 2 (P=0.03). This finding led us to conclude that sequential HBI is useless as consolidation treatment. The high-dose chemotherapy adopted in the second program enabled a proportion of patients to obtain long-term survival but, since the clinical results remain unsatisfactory, new treatment strategies are warranted
