Preoperative Aqueous Cytokine Levels are Associated With Endothelial Cell Loss After Descemet's Stripping Automated Endothelial Keratoplasty.

Purpose: To evaluate the association between endothelial cell density (ECD) after Descemet's stripping automated endothelial keratoplasty (DSAEK) and preoperative cytokine levels in the aqueous humor (AqH).

Methods: This prospective consecutive case series included 97 consecutive patients who underwent DSAEK (64 eyes) or cataract surgery (33 eyes). AqH samples were collected at the beginning of each surgery.

Association between corneal endothelial cell densities and elevated cytokine levels in the aqueous humor.

Annual reduction rate of corneal endothelial cell density (ECD) varies among etiologies, however, the cause of chronic endothelial cell loss is still unknown. We recently reported the elevation of inflammatory cytokines in the aqueous humor (AqH) in eyes with bullous keratopathy and low ECD. To evaluate the association between ECD and aqueous cytokine levels, we collected a total of 157 AqH samples prospectively.

Elevated Aqueous Cytokine Levels in Eyes With Ocular Surface Diseases.

Purpose: To evaluate cytokine and protein levels in the aqueous humor (AqH) of eyes with ocular surface diseases.

Design: Prospective consecutive case series.

Methods: This study includes 14 patients (aged 62.

Preoperative Aqueous Cytokine Levels Are Associated With a Rapid Reduction in Endothelial Cells After Penetrating Keratoplasty.

Purpose: To evaluate the influence of preoperative inflammatory cytokine levels in the aqueous humor (AqH) on the endothelial cell density (ECD) after penetrating keratoplasty (PKP).

Design: Prospective, interventional, consecutive case series.

Methods: This study includes 70 consecutive patients (mean age 73.

Iris Damage Is Associated With Elevated Cytokine Levels in Aqueous Humor.

Purpose: To evaluate the association between iris damage and cytokine levels in the aqueous humor (AqH).

Methods: A total of 201 AqH samples from 201 consecutive patients (mean age 73.7 ± 10.

Elevated Cytokine Levels in the Aqueous Humor of Eyes With Bullous Keratopathy and Low Endothelial Cell Density.

Purpose: To evaluate cytokine levels in the aqueous humor (AqH) of eyes with bullous keratopathy (BK) and low endothelial cell density (ECD).

Methods: A total of 145 AqH samples (60 BK, 16 low ECD, 35 corneal diseases with normal ECD, and 34 normal controls) were collected from consecutive patients who underwent corneal transplantation or cataract surgery. None of the patients had any clinically apparent inflammation at the time of AqH collection.

Molecular epidemiology of Newcastle disease virus isolates from vaccinated commercial poultry farms in non-epidemic areas of Japan.

Background: Newcastle Disease (ND) is a highly contagious and economically devastating disease of poultry. At present, limited molecular epidemiological data are available regarding the causes of ND outbreaks in vaccinated commercial poultry farms. Knowing the genomic characteristics of Newcastle disease virus (NDV) infecting commercial poultry operations in spite of vaccination might give important insights on the infection dynamics of these viruses.

Epizootiologic role of feeds in the epidemiology of Salmonella Senftenberg contamination in commercial layer farms in eastern Japan.

In total, 40 commercial layer farms and 32 replacement pullet farms with a combined population of 7.5 million adult layers and 6.6 million replacement pullets from six prefectures in eastern Japan were investigated for Salmonella Senftenberg contamination.

Transmission and shedding patterns of Salmonella in naturally infected captive wild roof rats (Rattus rattus) from a Salmonella-contaminated layer farm.

Rodents play a major role in the transmission and maintenance of Salmonella contamination cycles in poultry facilities. However, very limited field data are available regarding the transmission routes, infection cycle, and shedding patterns of Salmonella by naturally infected wild rodents from commercial layer farms. In this study, a total of 128 resident wild roof rats (Rattus ratus) were captured from a Salmonella-contaminated layer facility.

Comparison of the prevalence of Salmonella infection in layer hens from commercial layer farms with high and low rodent densities.

A comparison on the prevalence of Salmonella infection in layer hens from commercial layer farms with high and low rodent densities was investigated. Out of 280 laying hens sampled from three commercial layer farms with high rodent densities, Salmonella enterica subsp. enterica serovar Enteritidis (Salmonella Enteritidis) was isolated from 20 (7.

Evaluation of in vivo genotoxic potential of fenofibrate in rats subjected to two-week repeated oral administration.

Fenofibrate (FF), a peroxisome proliferator-activated receptor-alpha agonist, has been used as one of the hypolipidemic drugs in man and induces oxidative stress and promotes hepatocarcinogenesis in the liver of rodents. This chemical belongs to a class of non-genotoxic carcinogens, but DNA damage secondary to oxidative stress resulting from reactive oxygen species (ROS) generation is suspected in rodents given this chemical. To examine whether FF has genotoxic potential, partially hepatectomized F344 male rats were treated orally with 0, 1,000 or 2,000 mg/kg of FF for 2 weeks, followed by diet containing 0.

Evaluation of in vivo liver genotoxic potential of Wy-14,643 and piperonyl butoxide in rats subjected to two-week repeated oral administration.

Wy-14,643 (WY), a peroxisome proliferator-activated receptor-alpha agonist, and piperonyl butoxide (PBO), a pesticide synergist, induce oxidative stress and promote hepatocarcinogenesis in the liver of rodents. These chemicals belong to a class of non-genotoxic carcinogens, but DNA damage secondary to the oxidative stress resulting from reactive oxygen species generation is suspected in rodents given these chemicals. To examine whether WY or PBO have DNA-damaging potential in livers of rats subjected to repeated oral administration for 14 days, the in vivo liver comet assay was performed in partially hepatectomized rats, and the expression of some DNA-repair genes was examined.

Antioxidant enzymatically modified isoquercitrin suppresses the development of liver preneoplastic lesions in rats induced by beta-naphthoflavone.

To investigate the modifying effect of enzymatically modified isoquercitrin (EMIQ) on hepatocellular tumor promotion induced by beta-naphthoflavone (BNF) treatment, male rats were administered a single intraperitoneal injection of N-diethylnitrosamine (DEN) and were fed a diet containing BNF (0.5%) for 6 weeks with or without EMIQ (0.2%) in the drinking water after DEN initiation.

A case report of an uncommon sex-cord stromal tumor consisted of luteal and sertoli cells in a spayed bitch.

We report a rare case of benign sex cord-stromal tumor consisted largely of luteoma with minor portion of Sertoli cell tumor located at the position of the left ovary excision in an 11-year-old ovariectomized bitch. Granulosa cell component was lacking, and both luteal and Sertoli cell portions were entirely positive for inhibin alpha and neuron-specific enolase, whereas luteoma portion alone was positive for Wilms' tumor-1 (WT1), immunohistochemically. The results suggest that this tumor is a possible complication of incomplete ovarian excision at the time of ovariectomy and consisted of uncommon hybrid of luteal and Sertoli cells to be diagnosed as an unclassified sex cord-stromal tumor if applied in human cases.
