| transmural myocardial infarction | Infarction that involves the whole thickness of the heart muscle from endocardium to epicardium. Synonym: through-and-through myocardial infarction. (05 Mar 2000) |
| transmural pressure | Pressure across the wall of a cardiac chamber or of a blood vessel. In the heart, transmural pressure is the resultant of the intracavitary pressure minus the extracavitary (i.e., pericardial) pressure and is the distending, i.e., true filling, pressure of the cardiac chamber of measurement when this is done during diastole. Since the pericardial pressure normally approximates zero, the filling pressure (usually equal to ventricular diastolic mean pressure), obviating the complexities of measuring pericardial pressure.

| transom | 1. A horizontal crossbar in a window, over a door, or between a door and a window above it. Transom is the horizontal, as mullion is the vertical, bar across an opening. 2. One of the principal transverse timbers of the stern, bolted to the sternpost and giving shape to the stern structure; called also transsummer. 3. The piece of wood or iron connecting the cheeks of some gun carriages. 4. <surgery> The vane of a cross-staff. 5. One of the crossbeams connecting the side frames of a truck with each other. Transom knees A window divided horizontally by a transom or transoms. A window over a door, with a transom between. Origin: Probably fr. L. Transtrum a crossbeam, transom, from trans across. Cf.

| transduction |
Transduction is the process in which bacterial DNA is moved from one bacterium to another by a bacterial virus (a bacteriophage, commonly called a phage). When bacteriophages (viruses that infect bacteria) infect a bacterial cell, their normal mode of reproduction is to harness the DNA replication machinery of the host bacterial cell and make numerous copies of their own DNA or RNA. ...

| transfection |
Introducing DNA into eukaryotic cells, such as animal cells, is called transfection. Transfection typically involves opening transient "holes" or gates in cells to allow the entry of extracellular molecules, typically supercoiled plasmid DNA, but also siRNA, among others. Several different transfection techniques are available, including calcium phosphate transfection, lipofection, electroporation, heat shock, and proprietary transfection reagents such as Fugene. ...

| transfer RNA |
Transfer RNA (abbreviated tRNA) is a small RNA chain (74-93 nucleotides) that transfers a specific amino acid to a growing polypeptide chain at the ribosomal site of protein synthesis during translation. It has sites for amino-acid attachment and codon (a particular sequence of 3 bases) recognition. The codon recognition is different for each tRNA and is determined by the anticodon region, which contains the complementary bases to the ones encountered on the mRNA. ...

| transposon |
Transposons are sequences of DNA that can move around to different positions within the genome of a single cell, a process called Transposition. In the process, they can cause mutations and change the amount of DNA in the genome. Transposons are also called "jumping genes" or "mobile genetic elements". There are a variety of mobile genetic elements, they can be grouped based on their mechanism of transposition. ...

| transsexual |
A transsexual (sometimes transexual) person establishes a permanent identity with the opposite gender to their assigned (usually at birth) sex. Transsexual men and women make or desire to make a transition from their birth sex to that of the opposite sex, with some type of medical alteration (gender reassignment therapy) to their body. The stereotypical explanation is of a "woman trapped in a man's body" or vice versa, although many in the transsexual community reject this formulation. ...
