However, the Moon is not the only possible source for space resources. Asteroids, in particular near-Earth asteroids (NEAs), can provide an alternative source for propellant and other materials, sometimes at lower cost. There are an expected 4000 NEAs that require less propellant (delta-V) per trip

Assessment of DNA damage by comet assay and ChEs activity has been widely used as a biomarker of genotoxicity and exposure to pesticide respectively, to measure the risk related to pesticides in the exposed population [15]. Very few studies have explored the association between DNA damage and worker

Introduction Oral contraceptives (OCs) are the most commonly used medication for contraception all over the world and are also used in the treatment of menstrual disturbances and hyperandrogenism in women with polycystic ovary syndrome [1]. The impact of OC steroids on cardiovascular pathophysiol

Primary renal PNET was first reported by Seemayer et al in 1975. The possible etiology of rPNET is based on the theory of neural cell intussusception in the kidney during development that initiates the tumorigenesis. rPNET most commonly affects young adults, with a mean age of 30.4 years and male pr

Conclusion Acknowledgments Introduction Arsenic (As) is one of the most toxic metals derived from the natural environment in soil, air and well water. It has two oxidative states: a trivalent form, arsenite, and a pentavalent form, arsenate. The inorganic As is more toxic than organic As. A

For in vitro expression analysis of CXCL8 and CXCRs by stimulated leucocytes, peripheral blood leucocytes (PBLs) were isolated using Percoll density gradient centrifugation as described earlier . Cell suspensions were adjusted to 5×10/ml. Four milliliters of tissue culture medium were plated per wel

An intriguing feature of the pre and postsynaptic processes at the level of the VTA that have been shown to be mediated by CRF2 receptors [9], [34] is that they are exerted only by agonists with high affinity for both CRF2 receptors and CRF-BP. The four endogenous peptides of the CRF system have hig

As the primary model we selected LDL-receptor knockout mice because these resemble the human plasma lipoprotein profile more closely. Currently, genetic models with reduced milk cholesterol content, which mimic cholesterol-free formula feeding, are unavailable. Thus, instead of modifying milk choles

Our finding that VEGF-A induced downregulation of EphB4 is VEGFR2 dependent (Fig. 4A) is not surprising because VEGFR2 is the primary signaling receptor of VEGF-A in EC [34]. However, our finding that VEGF-A induced upregulation of dll4 cannabinoid receptors is not inhibited by VEGFR2 inhibition su

In conclusion, our study has demonstrated that PGE2 stimulates expression of survivin in hepatocellular carcinoma cells. Although there are 4 subtypes of EP receptors, the EP1 receptor appears to be the predominant receptor that regulates PGE2-induced expression of survivin, mainly through trans-act

It is without doubt that the vagina plays a significant role in the perception of coital stimulation leading to sexual arousal and, finally, orgasm. In response to sensory stimulation, relaxation of vaginal vascular and nonvascular smooth muscle occurs, resulting in an increase in local blood flow a

However, in many of the above mentioned studies, the NaCl concentrations in the extraction buffers were different from those used here. For instance, in the study that performed cathepsin D extraction from human AD Adarotene tissue, the concentration was 150mM [30], while that for the extraction of
