Tramadol Influences Cellular Metabolism and Autophagy in Germ and Sertoli Cells; Exercise Training as A Potential Ameliorative Strategy.

Objective: Dysregulation of lipid and carbohydrate/fatty acid (FA) balance in Sertoli and germ cells alters the NADP+/ NADPH ratio, resulting in metabolic autophagy in testicles. Tramadol (TRA) adversely affects spermatogenesis development, and it is not reversed within short periods of time after withdrawal. Therefore, the present study aimed to examine the boosting effect of different exercise training protocols (ETPs) on TRA-induced detrimental effects after withdrawal.

The effect of regular aerobic exercise on reverse cholesterol transport A1 and apo lipoprotein a-I gene expression in inactive women.

Background: Atherosclerotic cardiovascular disease is currently a cause of mortality in some parts of the world. The ATP-Binding Cassette Transporter (ABCA1) gene prepares instructions to produce the ATP-binding cassette transporter protein whose operation is for export of phospholipids and cholesterol, outside cells where they are limited to Apolipoprotein A1 (apoA1). Increased ABCA1 activity could inhibit atherosclerosis.

Study of SH2D1A gene mutation in paediatric patients with B-cell lymphoma.

Background: X-linked lymphoproliferative disease (XLP) is an often fatal inherited immunodeficiency disorder characterised by fulminant infectious mononucleosis, acquired haemophagocytic lymphohistiocytosis, dysgammaglobulinaemia and malignant lymphoma. Given the paucity of data on the genetic stratification of XLP gene mutations in paediatric patients diagnosed with B-cell lymphoma, we sought to determine the existence of such association in the present study.

Methods: We studied 20 male subjects diagnosed with non-Hodgkin B-cell lymphoma.

Calcium phosphate combination biomaterials as human mesenchymal stem cell delivery vehicles for bone repair.

A new class of biomimetic, bioresorbable apatitic calcium phosphate cement (CPC) was recently developed. The handling characteristics, and the ability to harden at body temperature in the presence of physiological saline, make this material an attractive clinical bone substitute and delivery vehicle for therapeutic agents in orthopedic applications. The major challenge with the material is formulating an injectable paste with options for cell delivery, in order to regenerate new bone faster and with high quality.

Radiologic findings in seven patients with fibrodysplasia ossificans progressiva.

Fibrodysplasia ossificans progressiva is a rare and disabling syndrome, which is characterized by heterotopic ossifications and skeletal deformities. So far, around 200 patients with fibrodysplasia ossificans progressiva have been reported in the world literature. Herein, we analyze the clinical records of 7 known cases of fibrodysplasia ossificans progressiva from Iran who were admitted to the pediatrics wards of our centers between 1983 and 2002, and present the radiologic findings.

alpha-BSM: a biomimetic bone substitute and drug delivery vehicle.

alpha-BSM is a biomimetic endothermically setting apatitic calcium phosphate bone substitute material. Its injectability and ability to harden at body temperature in the presence of physiologic saline, and other buffering agents, makes it an attractive clinical bone substitute and delivery vehicle for therapeutic agents in orthopaedic and dental applications. In osseous tissue, alpha-BSM alone remodels into bone and promotes bone healing.

Resorbable calcium phosphate bone substitute.

The in vitro and in vivo properties of a novel, fully resorbable, apatitic calcium phosphate bone substitute (ABS) are described. The ABS was prepared from calcium phosphate precursors that were hydrated to form an injectable paste that hardens endothermically at 37 degrees C to form a poorly crystalline apatitic calcium phosphate (PCA). The PCA reaction product is stable in vivo as determined by FTIR and XRD analysis of rabbit intramuscular implants of ABS retrieved 4, 7, and 14 days postimplantation.
