PURPOSE Melatonin's function in human vision is far from understood, in part because of the lack of information on its cellular targets. Therefore, expression and localization of the MT(1) melatonin receptor in human retina was examined. METHODS Postmortem nonpathologic human eyes from nine donors were investigated, three by reverse transcription-polymerase chain reaction (RT-PCR) for MT(1) a...

BACKGROUND Medical thoracoscopy (MT) is a minimally invasive, endoscopic procedure for exploration of the pleural cavity under conscious sedation and local anesthesia. MT has been performed at the Seoul National University Hospital since February 2014. This paper summarizes the findings and outcomes of MT cases at this hospital. METHODS Patients who had undergone MT were enrolled in the study...

Localization of metallothionein (MT) -I & -II and MT-III and its significance in the brain aging in dogs were examined using immunohistological and molecular pathological techniques. MT-I & -II immunohistochemistry showed positive staining in the hypertrophic astrocytes throughout the aged dog brains; these MT-I & -II immunoreactive astrocytes were predominant in the cerebral cortex and around ...

Unlike most animal mitochondrial (mt) genomes, which encode a set of 22 transfer RNAs (tRNAs) sufficient for mt protein synthesis, those of cnidarians have only retained one or two tRNA genes. Whether the missing cnidarian mt-tRNA genes relocated outside the main mt chromosome or were lost remains unclear. It is also unknown what impact the loss of tRNA genes had on other components of the mt t...

The Metallothionein (MT) is a protein which has several interesting biological effects and has been demonstrated increase focus on the role of MT in various biological systems in the past three decades. The studies on the role of MT were limited with few areas like apoptosis and antioxidants in selected organs even fifty years after its discovery. Now acknowledge the exploration of various isof...

The New World jacanas, Jacana spinosa (Mexico to Panama and also the West Indies) and Jacana jacana (Panama and South America), are polyandrous freshwater waders that are common throughout the Neotropics. These two species hybridize narrowly at their contact zone in Panama, and as part of a study of the hybrid zone dynamics, we present complete, annotated mitochondrial genomes for both species....

Somatic mutations of the human mitochondrial genome can be a possible determinant of atherosclerosis. To test this possibility, forty mitochondrial mutations were analyzed in the present study in order to see which of these mutations might be associated with atherosclerosis. Ten mitochondrial mutations belonging to mitochondrial genes MT-RNR1 (rRNA 12S); MT-TL1 (tRNA-Leu, recognizes UUR); MT-TL...

Motor proteins in living cells, such as kinesin and dynein, can move processively along the microtubule (MT), and can also detach from or attach to MT stochastically. Experiments found that the traffic of motors along MT may be jammed; thus various theoretical models were designed to understand this process. However, previous studies mainly focused on motor attachment/detachment rate dependent ...

Research has linked Mirror-Touch (MT) synaesthesia with enhanced empathy. We test the largest sample of MT synaesthetes to date to examine two claims that have been previously made: that MT synaesthetes (1) have superior empathy; and (2) only ever experience their MT synaesthesia in response to viewing a person being touched. Given that autism has been suggested to involve deficits in cognitive...

MT has always attracted a good deal of public attention, particularly that of people involved in translation. It has provoked controversies, sometimes very fierce, and unfounded worries among translators and their administrators. This happened partly because people put too much expectation on the possibility of MT. People talked about MT systems or the possibility of MT systems without using th...
