Species loss due to human activities is occurring at an unprecedented pace ( Barnosky et al., 2011 ), and over the last few decades, botanic gardens have responded by expanding their conservation activities ( CBD, 2010 ). Botanic gardens play a particularly critical role in the development of ex situ (off -site) collections of threatened plant species, and the botanic garden community has helpe...

This study aimed to establish a cryopreservation protocol for embryogenic cultures of A. angustifolia, enabling the ex situ conservation of the species. Embryogenic cultures were established from immature seeds and treated with variations of the cryoprotectant solutions SuDG, SoD and PVS2 prior to immersion in liquid nitrogen. Cell viability was evaluated after 30, 60 and 90 days of re-growth. ...

Dielectric and field-dependent polarization response of palladium iodide nanoparticles under both in situ ex condition.

Endurance exercise training (Ex) has been shown to increase maximal skeletal muscle blood flow. The purpose of this study was to test the hypothesis that increased endothelium-dependent vasodilation is associated with the Ex-induced increase in muscle blood flow. Furthermore, we hypothesized that enhanced endothelium-dependent dilation is confined to vessels in high-oxidative muscles that are r...

In this study we test the hypotheses that mechanical bone strength in elderly individuals displays substantial heterogeneity among clinically relevant skeletal sites, that ex situ dual-energy X-ray absorptiometry (DXA) provides better estimates of bone strength than in situ DXA, but that a site-specific approach of bone densitometry is nevertheless superior for optimal prediction of bone failur...

Khaidarkan, Batken Province, Kyrgyzstan is home to one of the world’s largest and last primary mercury mines. Doctors without Borders (MSF) Ministry Health (MOH) have found that region has an elevated rate non-communicable diseases (NCD) within country. NCD can be caused by environmental pollution. A human health risk assessment was conducted investigate heavy metal exposure. Using a hand-held ...

Formation of hydroxylapatite through the precipitation and evolution of calcium phosphate precursor phases under varying conditions of temperature (25–90 °C), pH (6.5–9.0), and calcium to phosphorus ratio (1.0, 1.33, 1.5, and 1.67) comparable to those found in many sediments and soils were studied. The products of low-temperature precipitation were analyzed by ex situ X-ray diffraction and SEM,...

P-glycoprotein (P-gp) and cytochrome P450 3A4 (CYP3A4) play a significant role in the disposition and elimination of drugs. The objective of this study was to investigate the mechanism underlying the interaction between sitagliptin (substrate of P-gp and CYP3A4) and verapamil (known modulator of P-gp and CYP3A4) using in vivo, ex vivo and in situ models. Rats were treated with sitagliptin (10 m...
