Two new diterpenoids from Ballota limbata. (1/2)
Two new clerodane-type diterpenoids trivially named as ballotenic acid (1) and ballodiolic acid (2) have been isolated from Ballota limbata along with three the known compounds; beta-amyrin, oleanolic acid, and beta-sitosterol. The structure elucidation of the new compounds was based primarily on two-dimensional (2D)-NMR techniques including correlation spectroscopy (COSY), heteronuclear multiple quantum coherence (HMQC), heteronuclear multiple bond correlation (HMBC), and nuclear Overhauser effect (NOE) experiments. Compounds 1 and 2 displayed inhibitory potential against lipoxygenase enzyme in a concentration-dependent fashion with IC(50) values of 99.6 microM and 38.3 microM, respectively. (+info)Genetic diversity within and among sinai populations of three Ballota species (Lamiaceae). (2/2)
Ballota undulata, Ballota kaiseri, and Ballota saxatilis are very rare (and endemic--B. kaiseri), threatened species growing in St. Catherine Protectorate, southern Sinai, Egypt. They are subjected to a number of threats that have caused populations to decline in both number and size. For the long-term survival of these species, an appropriate conservation strategy for the maintenance of their genetic variation should be developed. This study measures genetic diversity within and among populations of these Ballota species and determines the conservation implications of the results. The genetic analyses demonstrated that the three Ballota species maintain relatively high levels of genetic diversity (He = 0.195-0.317) and that most of the their genetic diversity was found within populations (GST = 0.045-0.099). Indirect estimates of historical gene flow for B. undulata and B. saxatilis were relatively high (Nm(W) = 5.25 and 3.37, respectively) but suggest that there is somewhat less gene movement among B. kaiseri populations (Nm(W) = 2.29). The levels of genetic diversity maintained within populations of the three Ballota species indicate that an appropriate sampling design for ex situ safeguarding should capture the majority of the genetic diversity found within these taxa. (+info)I am not aware of a medical definition for "Ballota." The term "Ballota" is most commonly used to refer to a genus of plants in the mint family, also known as dead nettle or pokeroot. It does not have any widely accepted or recognized medical meaning or application. If you have encountered this term in a medical context, I would be happy to help further clarify or provide more information if you could provide additional context.
Electrophoresis, starch gel is a type of electrophoretic technique used in laboratory settings for the separation and analysis of large biomolecules such as DNA, RNA, and proteins. In this method, a gel made from cooked starch is used as the supporting matrix for the molecules being separated.
The sample containing the mixture of biomolecules is loaded onto the gel and an electric field is applied, causing the negatively charged molecules to migrate towards the positive electrode. The starch gel acts as a molecular sieve, with smaller molecules moving more quickly through the gel than larger ones. This results in the separation of the mixture into individual components based on their size and charge.
Once the separation is complete, the gel can be stained to visualize the separated bands. Different staining techniques are used depending on the type of biomolecule being analyzed. For example, proteins can be stained with dyes such as Coomassie Brilliant Blue or silver nitrate, while nucleic acids can be stained with dyes such as ethidium bromide.
Starch gel electrophoresis is a relatively simple and inexpensive technique that has been widely used in molecular biology research and diagnostic applications. However, it has largely been replaced by other electrophoretic techniques, such as polyacrylamide gel electrophoresis (PAGE), which offer higher resolution and can be automated for high-throughput analysis.
