The booklouse, Liposcelis bostrychophila, is a worldwide pest of stored products. For decades, only thelytokous parthenogenetic reproduction was documented in L. bostrychophila. Male L. bostrychophila were first found in Hawaii in 2002. In 2009, a sexual strain was found in Arizona. We examined the morphology of both males and females of the Arizona strain and compared the Arizona sexual strain...

Background: The use of computers among students is now a necessary, especially for medical both study and entertainment. This situation can increase the risk Computer Vision Syndrome (CVS). (CVS) bunch symptoms on eye vision-related problems by prolonged (such as tablets, e-readers, smartphones, etc.).
 Objective: aimed to find out representation CVS experienced in Medical Faculty Universi...

The NH strain of mice was developed for the purpose of producing the highest possible degree of biological variability without the interfering incidence of spontaneous tumors. In order to do this, mice of three separate inbred strains were mated seriatim. The above strains were the CBA, the JK, and the N. Mice of the CBA strain have reached the forty-eighth generation of a pedigreed brother-to-...

PURPOSE Klebsiella pneumoniae is a common cause of endogenous bacterial endophthalmitis, a disease that frequently results in a poor visual outcome. Hypermucoviscosity has been identified as a virulence factor among clinical bacteremia isolates of K. pneumoniae. In this study, an experimental murine model of K. pneumoniae endophthalmitis was established, and the role of hypermucoviscosity in it...

The pattern of breathing during sleep could be a heritable trait. Our intent was to test this genetic hypothesis in inbred mouse strains known to vary in breathing patterns during wakefulness (Han F, Subramanian S, Dick TE, Dreshaj IA, and Strohl KP. J Appl Physiol 91: 1962-1970, 2001; Han F, Subramanian S, Price ER, Nadeau J, and Strohl KP, J Appl Physiol 92: 1133-1140, 2002) to determine whet...

bebig ruthenium-106 ophthalmic plaques have been used for treatment of uveal melanoma, retinoblastoma, melanoma of the iris and other special applications for many years. the plaques consist of a thin film of 106ru, a beta emitter, encapsulated in pure silver. the present work proposes a new mathematical eye model for ophthalmic brachytherapy dosimetry. this new model includes detailed descript...

Inoculation of 200 mean egg infectious doses (EID(50)) of lentogenic Newcastle disease virus strain B1 (NDV-B1) into the air sac of 4-day-old specific-pathogen-free chicks provided significant protection against challenge of the air sac with 100 chicken mean lethal doses (LD(50)) of velogenic NDV-H but no protection against reinfection when the challenge was by the eye. Conversely, inoculation ...

Ocular dominance plasticity is a widely studied model of experience-dependent cortical plasticity. It has been shown that potentiation of open eye responses resulting from monocular deprivation relies on a homeostatic response to loss of input from the closed eye, but the mechanisms by which this occurs are not fully understood. The role of GluA1 in the homeostatic component of ocular dominance...

PURPOSE To study the role of natural killer cells in the dissemination of virus to the eye and virus growth as well as the production of lesions in the eye during primary infection of murine cytomegalovirus. METHODS Virus activity and lesion production by murine cytomegalovirus in various organs of natural killer cell-depleted BALB/c strain of inbred mice were compared with those of immunocom...

Vaccination is an option for controlling Mycoplasma gallisepticum or M. synoviae when biosecurity measures fail to prevent the infection of poultry flocks with these mycoplasmas. Both killed vaccines (bacterins) and living vaccines are currently in commercial use. Bacterins usually contain an oil emulsion adjuvant and are administered by subcutaneous or intramuscular injection. They can reduce ...
