Nutrient Profile of Native
Woody Species and Medicinal Plants in Northeastern Mexico:
A
Synthesis Woody plants and medicinal plants possesss various macro nutrients
and micronutrients. These are essential to bring about the growth and
development of the plants. These because of their medicinal values are used
traditionally to cure various diseases. We made a short synthesis of researches
undertaken on macro and micronutrients of woody species and medicinal plants.
Woody plants of Tamaulipan Thornscrubs in the semiarid regions are of great
economic importance for various uses such as timber for furniture, fences,
firewood and serve as sources of forage for wild animal grazing. Few studies
are undertaken on nutrient contents of woody plants.
Magic Angle Spinning NMR
Metabolomics
Nuclear
Magnetic Resonance (NMR) spectroscopy is a nondestructive, quantitative,
reproducible, untargeted and unbiased method that requires no or minimal sample
preparation, and is one of the leading analytical tools for metabolomics
research. The easy quantification and the no need of prior knowledge about
compounds present in a sample associated with NMR are advantageous over other
techniques. 1H NMR is especially attractive because protons are present in
virtually all metabolites and its NMR sensitivity is high, enabling the
simultaneous identification and monitoring of a wide range of low molecular
weight metabolites.
Salivary Progesterone as a
Biomarker in Pregnancy
Progesterone
is considered as the pregnancy hormone. Already in 1958 Short was able to
determine progesterone in blood and found that during pregnancy its levels
increase from <0.1 μg/100 mL (nonpregnant) up to 87 μg/100 ml. In addition,
Eton and Short found that in early abortion or premature delivery the
concentration of progesterone was relatively low, which finding were confirmed
by Wiest for fetal death. The role of progesterone during pregnancy includes
the preparation of the uterus for implantation, to keep the uterus quiescent
during gestation and lower immune responses of the mother.
