The origin of brown adipocytes arising in white adipose tissue (WAT) after cold acclimatization is unclear. Here, we demonstrate that several UCP1-immunoreactive brown adipocytes occurring in WAT after cold acclimatization have a mixed morphology (paucilocular adipocytes). These cells also had a mixed mitochondrioma with classic "brown" and "white" mitochondria, suggesting intermediate steps in...
We studied sea-level residents during 13 days of altitude acclimatization to determine 1) altitude acclimatization effects on erythrocyte volume and plasma volume, 2) if exogenous erythrocyte volume expansion alters subsequent erythrocyte volume and plasma volume adaptations, 3) if an increased blood oxygen content alters erythropoietin responses during altitude acclimatization, and 4) mechanis...
The effects of Duranta repens fruits were investigated on H2O2 induced oxidative cell death to evaluate its antioxidative potential in vitro. HEK293T cells were treated with different concentrations [0-1000 µg/ ml] of ethanol extract (E-Ex) and methanol extract (M-Ex) of D. repens for 24h, and then treated with 100 µM H2O2 for 24h. Cell viability, antioxidant parameters of cells, and antioxidan...
tissue culture methods provide tools to supplement traditional methods for collection, propagation and preservation of endangered plant species. in this study, in vitro propagation of diaphanoptera khorasanica rech.f., a rare and threatened plant species with limited distribution range and population was investigated. this species has a potential as an ornamental plant. single node explants wer...
Experimental leishmaniasis is widely used to study the effector functions of T helper cell subsets in vivo. Healing and nonhealing Leishmania major infections have been correlated with T helper 1 and T helper 2 responses, respectively. In the present study, we determined T cell effector functions ex vivo, without any further restimulation and compared them to those obtained following antigen-sp...
Protocol for development of zygotic embryos in vitro and acclimatization of Dragon’s Blood plantlets
An understanding of human responses to hypoxia is important for the health of millions of people worldwide who visit, live, or work in the hypoxic environment encountered at high altitudes. In spite of dozens of studies over the last 100 years, the basic mechanisms controlling acclimatization to hypoxia remain largely unknown. The AltitudeOmics project aimed to bridge this gap. Our goals were 1...
