Nineteen cases of suspected Crimean-Congo hemorrhagic fever reported from Turkey.

For the treatment of isolated full-thickness chondral lesion of the knee, m-AMI can be used effectively and may potentially accelerate recovery. A larger patient cohort and follow-up supported by histological analyses are necessary to determine long-term outcomes.

Objectives: To investigate the markers of endogenous coagulation/fibrinolysis and vascular endothelial cell function, and to assess the relationships between hemostatic parameters and diabetic vascular complications in type 2 diabetic patients. Materials and Methods: Coagulation and fibrinolysis parameters were measured in 92 type 2 diabetic patients (43 male, 49 female, mean age 50.1 ± 13.4 years) with (n = 44) and without (n = 48) vascular diabetic complications, and in 40 nondiabetic healthy subjects (20 male, 20 female, mean age 49.8 ± 15.1 years). Common lipid parameters were also measured. Results: The plasma levels of fibrinogen, antithrombin III (AT III), plasminogen activator inhibitor-1 (PAI-1), von Willebrand factor (vWF) activity and prothrombin time were found to be significantly increased in the type 2 diabetic patients compared with the healthy subjects. Glycosylated hemoglobin lc was inversely correlated with plasma protein S and activated prothrombin time. Protein C and S activities were positively correlated with plasma vWF activity, and were negatively correlated with plasma t-PA levels. vWF activity was negatively correlated with plasma t-PA levels. AT III levels were positively correlated with plasma total cholesterol levels, plasma low density lipoprotein cholesterol levels, plasma triglycerides and D-dimer levels. Plasma PAI-1 levels and factor V activity in diabetic patients with microvascular complications were significantly higher than those of the diabetic patients without microvascular complications. The plasma PAI-1 and platelet count were increased in patients with diabetic retinopathy compared with the diabetic patients without retinopathy. Plasma PAI-1 levels and factor VII activity were significantly higher in the diabetic patients with nephropathy than in diabetic patients without nephropathy. Plasma concentrations of fibrinogen and PAI-1 were significantly higher in the diabetic patients with neuropathy than the diabetic patients without neuropathy. Conclusions: The data demonstrated that patients with type 2 diabetes mellitus had a hypercoagulable state and hypofibrinolysis, thereby indicating that activation of coagulation with a reduced fibrinolytic activity may contribute to the increased risk of vascular disease in type 2 diabetic patients.

Conventional tracheal reconstruction techniques are not successful at restoring functional units in situations with extensive damage involving more than half the length of the trachea. For the first time, we investigated in vivo tissue-engineered trachea regeneration from a decellularized cadaveric trachea matrix with seeded adult adipose tissue-derived mesenchymal stem cells (MSCs) and investigated the integration of the matrix into the recipient tracheal side. For the procedure, 1.8-cm grafts were prepared from 3.5-cm tracheas of three donor rabbits. Then, tracheal grafts were rendered nonimmunogenic using a decellularization technique. MSCs isolated from recipient rabbit adipose tissue were cultured and marked before being seeded in the decellularized matrix. A total of 1.8 cm of the recipient tracheas was replaced with either a decellularized tracheal matrix (group 1) or tracheal matrix-seeded MSCs (group 2). Rabbits survived 17 ± 2 days in the first group, and the causes of death were separation in the anastomosis region, airway obstruction, and infection. In the second group, animals were sacrificed on the 30th, 60th, and 90th days of follow-up. Histopathological analysis revealed the integration of MSCs seeded-decellularized cadaveric tracheas to the recipient tracheal sides and increased angiogenesis. The MSCs were traced by fluorescence microscopy in the ciliated epithelium, under the epithelium, and in the cartilage of the integrated new trachea. Tracheas generated by autologous cells and tissue-engineering techniques will be a great source for the treatment of life-threatening tracheal injuries after the completion of related studies.

Background: Multiple Myeloma (MM) is a B cell neoplasm characterized by the clonal proliferation of plasma cells. Skeletal complications are found in up to 80% of myeloma patients at presentation and are major cause of morbidity.
