Single port laparoscopic surgery is changing the standard of care in surgical care like nothing since the laparoscopic technique was introduced 20 years ago. We present out technique of single port donor nephrectomy using the Gelpoint device. We have successfully performed this surgery in 100 patients.

DNA Base Pairing

Erwin Chargaff’s rules on DNA equivalence paved the way for the discovery of base pairing in DNA. Chargaff’s rules state that in a double-stranded DNA molecule, the amount of adenine (A) is equal to the amount of thymine (T); the amount of guanine (G) is equal to the amount of cytosine (C); and the sum of purines, A and G, is equal to the sum of pyrimidines, C and T (i.e., A+G = C+T). Later work by Watson and Crick revealed that in double-stranded DNA, A always forms two hydrogen bonds...

Endothelial corneal transplantation is a surgical technique for treatment of posterior corneal diseases. Mechanical microkeratome dissection to prepare tissue results in thinner, more symmetric grafts with less endothelial cell loss and improved outcomes. Dissections can be performed at the eye bank prior to corneal transplantation surgery.

Colpitts1 1 Department of Microbiology, Boston University School of Medicine, National Emerging Infections Diseases Laboratories, Boston, MA First discovered by Lederberg and Tatum in 1946, conjugation is a form of horizontal gene transfer between bacteria that relies on direct physical contact between two bacterial cells (1). Unlike other forms of gene transfer, such as transformation or transduction, conjugation is a naturally occurring process in which...

Sign Test for Matched Pairs

The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values. To conduct the sign test, we first calculate the differences in value between...
FAQs
The donor’s lone pair supplies the electron density required to connect with an electron-deficient center on the acceptor. This interaction produces a coordinate covalent bond, in which the bonding electron pair originates from one species. Examining the donor’s available lone pair and the acceptor’s electron deficiency helps explain why particular species associate and form coordination compounds.
A coordinate covalent interaction joins the species through a shared electron pair supplied by the donor. In related donor acceptor behavior, electrons may instead move between species, producing electron transfer and charge-transfer behavior. Distinguishing these outcomes helps chemists interpret whether an interaction primarily creates a bond, changes electronic distribution, or contributes to both bonding and reactivity.
Charge-transfer behavior reveals how electronic distribution changes when donor and acceptor species interact. This information can clarify reactivity and help explain why a pair has particular electronic properties. In chemistry, analyzing these changes supports the interpretation of molecular interactions and the design of functional materials whose electronic behavior depends on controlled donor acceptor relationships.
Their interactions can provide a chemical basis for recognizing and associating particular molecular partners. The same donor acceptor principles also help explain catalytic behavior, because electron donation and acceptance influence how reacting species interact. Studying these pairs therefore connects local electron-pair interactions with broader chemical processes involving selective association, reaction interpretation, and catalytic activity.
Analysis begins by identifying the species that supplies a lone pair and locating the electron-deficient center that receives it. Chemists then determine whether the interaction produces a coordinate covalent bond or shows related electron-transfer behavior. This approach connects the proposed electronic interaction with the formation of a coordination compound and its resulting chemical reactivity.
They are useful when a material’s behavior depends on controlled electronic properties or charge-transfer interactions. By selecting and studying complementary donor and acceptor species, chemists can interpret how electronic distributions arise within the system and use that understanding to guide functional-material design. The same framework links molecular-scale interactions with measurable material behavior and performance.
