This paper analyzes differential trends in rural depopulation and repopulation nine municipalities of Mexico's Mixteca Alta region, the southern state Oaxaca, based on census data interviews carried out 2019. From 1950 to 2000, study area experienced a substantial loss population, linked essentially out-migration Mexico City. However, from 2000 2020, four regained while remaining five continued...

Abstract Purpose Artificial organs might serve as alternative solutions for whole organ transplantation. Decellularization of a liver provides non-immunogenic matrix with the advantage three afferent systems, portal vein, hepatic artery and bile duct. This study aims to evaluate recellularization rat livers islets Langerhans via duct vein comparison different perfusion routes. Methods Rat were ...

Repopulation of cancer cells escaping lethal chemotherapy is a critical factor hindering treatment success. One strategy to inhibit tumor cell repopulation is the use of cytostatic compounds between courses of lethal chemotherapy. In this study, we tested the hypothesis that mifepristone (MF), a steroid compound with demonstrated growth inhibition activity in ovarian cancer, should be efficacio...

Peripheral blood lymphocytes of 46 recipients of lymphocyte-depleted bone marrow allografts were phenotypically analysed over a period of 1 year. We investigated the repopulation of lymphocyte subpopulations and their relation with clinical parameters such as graft-versus-host disease (GVHD), graft-versus-leukaemia and cytomegalovirus (CMV) infection. The number of repopulated T cells varied st...

There is increasing concern regarding radiation-related second-cancer risks in long-term radiotherapy survivors and a corresponding need to be able to predict cancer risks at high radiation doses. Although cancer risks at moderately low radiation doses are reasonably understood from atomic bomb survivor studies, there is much more uncertainty at the high doses used in radiotherapy. It has gener...

Trefoil factor TFF3 has been implicated in intestinal protection and repair. This study investigated the spatiotemporal relationship between TFF3 expression and morphological changes during intestinal damage and repair in a rat model of methotrexate-induced small intestinal mucositis. Intestinal tissues from rats with mucositis were collected daily for 10 days. Mucosal damage was characterized ...

OBJECTIVES To correlate the kinetics of B-cell repopulation with relapse after B-cell depletion therapy in SLE patients and address whether variation in relapse rate, B-cell numbers and phenotype are related to anti-dsDNA antibody levels. METHODS Sixty-one patients with refractory SLE were treated with a standard rituximab regimen. Clinical and serological measures of disease activity and B-c...

Advanced head and neck cancers are aggressive tumours, which require aggressive treatment. Treatment efficiency is often hindered by cancer cell repopulation during radiotherapy, which is due to various mechanisms triggered by the loss of tumour cells and involves both stem and differentiated cells. The aim of the current paper is to present in silico simulations of radiotherapy schedules on a ...

OBJECTIVES To analyse the role of thymic function and its association with cellular immunosenescence markers in patients with low-level CD4 T cell repopulation, despite complete HIV RNA replication control on highly active antiretroviral therapy (HAART). METHODS Cellular immunosenescence markers comparing patients with CD4 T cell counts or=48 weeks (n = 11) and patien...

Background/aims: Parenchymal central nervous system microglia are repopulated by bone marrow derived monocytes more slowly than any other reticuloendothelial cells. The contribution of bone marrow derived monocytes to the uninflammed retina has not been studied. The present study sought to determine repopulation of retinal microglia in uniflammed retina by bone marrow derived monocytes in bone ...
