The Use of Vitamins and Coenzyme Q10 for the Treatment of Vascular Occlusion Diseases Affecting the Retina.

Nutritional supplementation with antioxidants and vitamins is widely recommended in the treatment of vascular disorders affecting the retina, although there is insufficient evidence on its effectiveness. The vitamin-like compound coenzyme Q10 (CoQ10) is a nutritional supplement of current interest to treat neurodegenerative diseases. Here, we report a retrospective clinical case series study of 48 patients diagnosed with retinal vascular diseases, including non-arteritic ischemic optic neuropathy (NAION), retinal artery occlusion (RAO), and homonymous hemianopia or quadrantanopia following stroke, treated with oral supplementation with CoQ10 (100 mg per day) and vitamins.

A Descriptive Analysis of Body Composition Among Forest Firefighters in Spain.

Objective: To determine the body composition profile of forest firefighters. Data were collected from 701 forest firefighters.

Methods: We have carried out this analysis using a bioimpedance scale BC-601 of the brand Tanita ISO 9001 Certified.

Association study of high-frequency variants of gene with retinal vein occlusion in a Spanish population.

: To study the association of the most common methylenetetrahydrofolate reductase () genetic polymorphisms C677T and A1298C with retinal vein occlusion (RVO) in a Spanish population. : Case-control study involving 359 subjects, 183 unrelated native Spanish patients diagnosed with RVO, distributed in central or branch RVO, and 176 healthy controls. Two SNPs located in the gene , C677T (rs1801133) and A1298C (rs1801131) were analyzed by DNA sequencing and TaqMan assays.

Executive Stress Management: Physiological Load of Stress and Recovery in Executives on Workdays.

: The use of high-performance sports technology to describe the physiological load of stress and the quality of recovery in a population of executives during the workday. : Heart rate variability values were recorded during 48 h from which the relationship between stress/recovery quality (stress balance) was obtained for three differentiated time slots: work, after work, and night in a workday. : We observed a negative stress balance during the 24 h of measurement in the course of a workday, being negative at work and after work, and positive at night.

Long-term Results of Corneal Cross-linking for Terrien's Marginal Degeneration.

Purpose: To report the long-term clinical outcomes of a patient with Terrien's marginal degeneration who underwent successful peripheral corneal cross-linking (CXL) to arrest progression.

Methods: Clinical assessment included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), corneal topography, anterior segment optical coherence tomography, ultrasonic pachymetry, corneal hysteresis, and corneal resistance factor. Eccentric epithelium-off CXL was performed in both eyes after limbal conjunctival resection.

European eel () plasma biochemistry alerts about propanil stress.

Propanil stress response in the eel () was examined. Eels were exposed to 3.16 mg/L for 72 hr and allowed to recover for 96 hr.

Energy reserves mobilization in the yellow eel as herbicide exposure effect.

Thiobencarb and propanil are two of the most extensive used herbicides worldwide in rice cultivation. Especially scanty is the available information regarding the effect of herbicides on fish energy resources. In the present study, the effect of sublethal exposure to these herbicides on the energy reserves of juvenile eel Anguilla anguilla was compared.

Physiological effects of tricyclazole on zebrafish (Danio rerio) and post-exposure recovery.

Short-term effects of tricyclazole on male zebrafish (Danio rerio) physiology were examined joint to the degree of recovery after exposure. Fish were exposed to 142 microg/L (1/100 LC(50)-96 h) of tricyclazole for 7 (Exp.1) and 14 days (Exp.

Effects of propanil on the European eel Anguilla anguilla and post-exposure recovery using selected biomarkers as effect criteria.

The aim of this study was to assess the physiological response of Anguilla anguilla to propanil and the degree of recovery after being moved to clean water. Preliminary acute toxicity test was carried out in the laboratory and the median lethal concentration (LC50) at 96 h was calculated as 31.33 mg/L (29.

Eel ATPase activity as biomarker of thiobencarb exposure.

European eels (Anguilla anguilla) were exposed to a sublethal thiobencarb concentration of 0.22 mg/L in a flow-through system for 96 h. Mg(2+) and Na(+)-K(+) adenosine triphosphatase (ATPase) activities were evaluated in gill and muscle tissues at 2, 12, 24, 48, 72, and 96 h of thiobencarb exposure.

Development of a simple and sensitive technique for detection of point mutations in the K-ras oncogene.

We sought to develop a simple and sensitive method based on mutant allele-specific amplification (MASA) for the detection of point mutations in the k-ras oncogene in blood samples. We used MASA and three nested MASA methods to detect a point mutation (GGT-->GAT) in rat DHD cells at codon 12 of exon 1 of the k-ras gene. MASA allowed us to detect one k-ras mutated cell on a background of 10(7) normal cells.

Glutathione-dependent resistance of the European eel Anguilla anguilla to the herbicide molinate.

Eels of species Anguilla anguilla were exposed to 5/4 LC50 (41.8 mg/l) of the herbicide molinate for 96 h in a time to death (TTD) test. Glutathione content (GSx, GSH, GSSG), glutathione reductase (GR) and gamma-glutamyl transpeptidase (gamma-GT) activities were determined in the liver and muscle tissues of dead and surviving (intoxicated) animals and compared to control values (non-exposed eels).

Alterations on AChE activity of the fish Anguilla anguilla as response to herbicide-contaminated water.

The inhibition of both total and specific acetylcholinesterase activities was measured in the whole eyes of the yellow eel Anguilla anguilla after exposure to the carbamate thiobencarb. In vivo assays were conducted under a constant flow-through system of thiobencarb-contaminated water (1/60 LC(50) 96 h=0.22 ppm for 96 h) followed by a recovery period in clean water (192 h more).

Thiobencarb toxicity and plasma AChE inhibition in the European eel.

The acute toxicity of the herbicide thiobencarb (S-4-chlorobenzyl diethylthiocarbamate) was determined for the European eel (Anguilla anguilla). The 24, 48, 72 and 96 hours median lethal concentrations (LC50) were 25.7, 21.
