PURPOSE To investigate the ability of a portable pupillometer, capable of 20-second binocular recordings of the swinging flashlight test (SFT), to detect relative afferent pupillary defects (rAPDs). METHODS Pupillary response curves were recorded from both eyes in healthy volunteers (n = 22) with and without simulated rAPDs (using neutral density filters (NDFs)) and in abnormal patients (n = ...

El trébol “pata de pájaro” (Lotus corniculatus L.) es una leguminosa perenne con amplia distribución en las regiones templadas Europa, Asia Menor, Norte África y Sudamérica, forma parte más 100 especies que componen el complejo género Lotus. Su calidad nutritiva comparable a la alfalfa (Medicago sativa blanco (Trifolium repens L.), su consumo fresco no produce timpanismo ganado; además resisten...

We demonstrate a reliable method for mapping conventional loci and obtaining meiotic linkage data for the ciliated protozoan Tetrahymena thermophila. By coupling nullisomic deletion mapping with meiotic linkage mapping, loci known to be located on a particular chromosome or chromosome arm can be tested for recombination. This approach has been used to map three isozyme loci, EstA (Esterase A), ...

We present a physical map based on RAPD polymorphic fragments and sequence-tagged sites (STSs) for the repleta group species Drosophila buzzatii. One hundred forty-four RAPD markers have been used as probes for in situ hybridization to the polytene chromosomes, and positive results allowing the precise localization of 108 RAPDs were obtained. Of these, 73 behave as effectively unique markers fo...

Dalbergia oliveri is a leguminous tree of the Fabaceae family. This species is popular and valuable in Vietnam and is currently listed on the Vietnam Red List and on the IUCN Red List as endangered. Two PCR techniques using RAPD and inter-simple sequence repeat (ISSR) markers were used to make a comparative analysis of genetic diversity in this species. Fifty-six polymorphic primers (29 R...

Several cases are presented from Juniperus in which the use of RAPD (Random Amplified Polymorphic DNA = Sequence Inverted Repeats SIRs) have been very concordant with DNA sequence and biogeographic data. The use of the term 'Random' should be discouraged because the method is not 'Random' but depends on numerous inverted sequences found in DNA that accounts for hairpin loops important to define...

the applicability of rapds, aflps, and ssrs to examine genetic relationships in 36 populations of triticum boeoticum from west of iran was investigated. a total of 224 (135 polymorphic), 979 (429 polymorphic) and 246 (145 polymorphic) bands/alleles were detected using 14 rapd primers, 17 aflp primer combinations and 17 well distributed, mapped ssr markers, respectively. the polymorphic informat...

In this paper the authors have carried out simulation experiment to study the opto-electric properties of p+-p-n-n+ structured WurtziteGaN (Wz-GaN) Reach-Through Avalanche Photodiodes (RAPDs). The photo responsivity and optical gain of the device are obtained within the wavelength range of 300 to 450 nm using a novel modeling and simulation technique developed by the authors. Two optical illumi...

The one-seeded, serrate leaf margined junipers of Southwestern United States and northern Mexico consist of J. angosturana, J. californica, J. coahuilensis var. arizonica, J. c. var. coahuilensis, J. monosperma, J. pinchotii, J. occidentalis var. australis, J. o. var. occidentalis and J. osteosperma. Recent nrDNA and trnC-trnD sequence data were compared with RAPDs analysis and two of the taxa ...
