Histology of skeletal muscle reconstructed by means of the implantation of autologous adipose tissue: an experimental study.

Histology of skeletal muscle reconstructed by means of the implantation of autologous adipose tissue: an experimental study. Histol Histopathol. 2019 Sep 12;:18163 Authors: Leiva-Cepas F, Jimena I, Ruz-Caracuel I, Luque E, Villalba R, Peña-Amaro J Abstract The purpose of this study was to determine the histological characteristics of a skeletal muscle reconstructed by means of the implantation of autologous adipose tissue following an experimentally-induced volumetric muscle loss. A cylindrical piece in the belly of the rat anterior tibial muscle was removed. In the hole, inguinal subcutaneous adipose tissue of the same rat was grafted. Animals were sacrificed 7, 14, 21, 28 and 60 days posttransplantation. Histological, histochemical, immunohistochemical and morphometric techniques were used. At all times analyzed, the regenerative muscle fibers formed from the edges of the muscle tissue showed histological, histochemical and immunohistochemical differences in comparison with the control group. These differences are related to delays in the maturation process and are related to problems in reinnervation and disorientation of muscle fibers. The stains for MyoD and desmin showed that some myoblasts and myotubes seem to derive from the transplanted adipose tissue. After 60 days, the transplant area was 20% occupied by fibrosis and by 80% skeletal muscle. However, the neo-muscle was chaotically organized showing muscle fiber disorientation and centronu...

We report a rare case of HBV reactivation in a patient with HCV infection after DAA therapy. Patient concerns: In 1996, a 53-year-old female was identified as infected with HCV at a medical check-up, following which she visited our hospital. She was infected with HCV genotype 2b, and at follow up in 1997, was found to be hepatitis B surface antigen (HBsAg) and antibody against HBsAg negative, antibody against HBV core positive. She then experienced malignant lymphoma in 2001 at 58 years of age. Complete remission was achieved following chemotherapy and autologous peripheral blood stem cell transplantation. In 2014, she ...

BONE MARROW TRANSPLANTATION (BMT) also called haematopoietic stem cell transplant (HSCT) is the treatment of choice for many haematological diseases including haematological malignancies and different types of anaemia1. The number of HSCT is increasing every year, mainly because of advanced research that has allowed an expansion in the number of indications for which it has become the first-line therapy2. The long-term survival of patients that have undergone BMT continues to improve with several advances in transplantation techniques and supportive care practices.

Chronic graft-versus-host disease (cGvHD) is a severe complication of allogeneic hematopoietic stem cell transplantation that affects various organs leading to a reduced quality of life. The condition often requires enduring immunosuppressive therapy, which can also lead to the development of severe side effects. Several approaches including small molecule inhibitors, antibodies, cytokines, and cellular therapies are now being developed for the treatment of cGvHD, and some of these therapies have been or are currently tested in clinical trials. In this review, we discuss these emerging therapies with particular emphasis on...

Conclusion: Our results suggest that children who develop ARF during engraftment have better ICU survival rates than do those with other etiologies of ARF post-HSCT. Furthermore, fluid overload contributes to mortality in these children; therefore, strategies to prevent and address fluid overload should be considered.
