Fatty acids profile in patients after heart or renal transplantation who developed metabolic complications.

Purpose: Diabetes mellitus and hyperlipidemia are frequently observed after organ transplantation. It is known that in these disorders the fatty acid metabolism is impaired. The aim of this study was to compare the fatty acid profile in the heart and renal transplant recipients who developed metabolic disorders since there is no such research available.

Radial Tears of the Lateral Meniscus-Two Novel Repair Techniques: A Biomechanical Study.

Background: A common treatment for radial tears of the meniscus has historically been partial meniscectomy. Owing to the poor outcomes associated with partial meniscectomy, repair of the meniscus is an important treatment option. It is important to evaluate different repair techniques for radial tears of the meniscus.

Pituitary insufficiency following traumatic thoracic injury in an adolescent male patient: A case report and literature review.

Rationale: Traumatic thoracic injuries in adolescents are rare but could be connected with traumatic brain injuries (TBI) and development of chronic hypopituitarism. Early recognition of these endocrine problems is a significant challenge to clinicians. We present difficulties in diagnosis of hypothalamic-pituitary insufficiency following traumatic thoracic injury in adolescence.

High-performance Liquid Chromatography Measured Metabolites of Endogenous Catecholamines and Their Relations to Chronic Kidney Disease and High Blood Pressure in Heart Transplant Recipients.

Background: Patients after solid organ transplantation, especially heart and kidneys, are prone to be hypertensive. Recently chronic kidney disease and renalase metabolism of endogenous catecholamines are thought to make major contribution to the pathogenesis of hypertension.

Materials And Methods: We analyzed 75 heart recipients (80% male, 20% female), medium age 54.

Effects of Immunosuppressive Drugs on Serum Fatty Acids of Phospholipids Fraction in Renal Transplant Recipients.

Background: Immunosuppressive medications often cause posttransplant hyperlipidemia. The effects of cyclosporine (CsA) and tacrolimus (Tac) on lipid profile is well-known; however, there are very few studies related to the effect of these immunosuppressants on fatty acids (FA) of phosholipids fraction (PL) in renal transplant recipients (RTR). We sought to analyze the FA profile in PL fraction of RTR treated with Tac or CsA.

[Fatty acid profile in phospholipids fraction with regard to blood pressure control in the kidney transplant patients].

Introduction: Hypertension is diagnosed in over 50% of renal transplant patients, and its presence is associated with significantly increased risk of cardiovascular complications. The pathogenesis of hypertension in this group of patients is complex. The use of immunosuppressive drugs is among the most important risk factors due to their hypertension-inducing properties.

Effect of immunosuppressive therapy on the serum fatty acids of phospholipids fraction in patients after heart transplantation.

Background: The effects of tacrolimus (Tac) and cyclosporine (CsA) on lipid profile is well known; however, little is known about the changes in fatty acids (FA) of phosholipids fraction (PL) in heart transplant patients after treatment with these immunosuppressants. This study aimed to investigate the effect of Tac and CsA on serum FA of PL in heart transplant patients.

Methods: The study included 23 patients after heart transplantation on Tac (n = 14; group II) or CsA (n = 9; group I).

Course of depressive symptoms across pregnancy in African American women.

Introduction: Although African American women are at increased risk for antenatal depression, less is known regarding the course of antenatal depression symptoms among African American women. Because pregnancy is a state of rapid physical and mental changes, we examined if depression symptoms changed between the second and third trimesters in a sample of pregnant African American women.

Methods: A nonprobability sample of women was recruited from obstetrics clinics within a large Midwestern health system.

[Breaking bad news--information for doctors].

The article broaches the subject of breaking bad news. Medical doctors deal with such a problem frequently, not always well-prepared for their role. Obviously, each patient should be treated individually, not only because every disease is a unique case, but also because patients have their own hopes and expectations.

Inhibition of rhabdomyosarcoma's metastatic behavior through downregulation of MET receptor signaling.

Rhabdomyosarcoma (RMS) is a soft tissue sarcoma usually diagnosed in children. In advanced and metastatic stages the prognosis is often poor. RMS cell lines were used for evaluation of the role of MET receptor inhibition on chemotaxis and invasion.

High anti tumor activity against rhabdomyosarcoma cells and low normal cells cytotoxicity of heat shock protein 90 inhibitors, with special emphasis on 17-[2-(pyrrolidin-1-yl)ethyl]-aminno-17-demethoxygeldanamycin.

Rhabdomyosarcoma is a highly metastatic tumor, mostly observed in children and adolescence. When diagnosed at early stages it is mostly curable. However, in advanced or metastatic stages the 5-years survival rate is below 20%.

Role of the Wnt/beta-catenin network in regulating hematopoiesis.

The Wnt/beta-catenin pathway plays a significant role in several aspects of cell biology, including the stimulation of gene expression, growth, and mobility. Wnt proteins activate at least three cascades: Wnt/beta-catenin, Wnt/Ca(2+), and planar cell polarity. beta-Catenin is not only a very important element of many intracellular signaling pathways, including the Wnt pathway, but it also takes part in creating intercellular adhesive junctions.

Differential glycosylation of interleukin 2, the molecular basis for the NOD Idd3 type 1 diabetes gene?

The insulin-dependent diabetes (Idd) gene, Idd3, has been localised to a 0.35 cM region of chromosome 3 containing the structural gene for the cytokine interleukin 2 (IL-2). While variation of the N-terminal amino acid sequence of IL-2 has been shown to correlate with Idd3 allelic variation, differences in induction of proliferation by IL-2 allotypes have not been detected.

Congenic mapping of the type 1 diabetes locus, Idd3, to a 780-kb region of mouse chromosome 3: identification of a candidate segment of ancestral DNA by haplotype mapping.

Type 1 diabetes in the nonobese diabetic (NOD) mouse arises as a consequence of T cell-mediated destruction of the insulin-producing beta cells of the pancreas. Although little is known of the events that initiate and subsequently drive beta-cell destruction it is clear that the entire process is under complex genetic control. At present 19 loci have been mapped that influence the development of diabetes either at the level of initiation of insulitis or at the level of progression from insulitis to overt diabetes, or both.

Potent immunosuppressive C32-O-arylethyl ether derivatives of ascomycin with reduced toxicity.

The synthesis of C32-O-arylethyl ether derivatives of ascomycin that possess equivalent immunosuppressant activity but reduced toxicity, compared to FK-506, is described.

C32-O-imidazol-2-yl-methyl ether derivatives of the immunosuppressant ascomycin with improved therapeutic potential.

A series of C32-O-aralkyl ether derivatives of the FK-506 related macrolide ascomycin have been prepared based on an earlier reported C32-O-cinnamyl ether design. In the present study, the nature of the aryl tethering group was varied in an attempt to improve oral activity. An imidazol-2-yl-methyl tether was found to be superior among those investigated and has resulted in an ascomycin analog, L-733,725, with in vivo immunosuppressive activity comparable to FK-506 but with an improved therapeutic index.

A tacrolimus-related immunosuppressant with biochemical properties distinct from those of tacrolimus.

Background: Tacrolimus (FK506) is an immunosuppressive drug 50-100 times more potent than cyclosporine (CsA), the current mainstay of organ transplant rejection therapy. Despite being chemically unrelated, CsA and tacrolimus exert their immunosuppressive effects through the inhibition of calcineurin (CaN), a critical signaling molecule during T-lymphocyte activation. Although numerous clinical studies have proven the therapeutic efficacy of drugs within this class, tacrolimus and CsA also have a strikingly similar profile of unwanted side effects.
