With the changes in trends of disease pattern from infectious to chronic degenerative disease, cardiovascular disease has been considered as the major cause of death in *** studies have been done on the antioxidant effects of some vitamins in the prevention of chronic illness, but not many.in relation to the cardiovascular ***, the relation between antioxidant vitamins, mainly.α-tocopherol (α-T) and B-carotene (B-C), and coronary.artery.disease (CAD) such as angina pectoris and my.cardial infarction has been investigated in this *** blood samples were obtained from the CAD patients who were angiographically.diagnosed within a month (100 case group). Patients who had an experience of PTCA or CABG were excluded from the study. Control subjects were healthy.adults who had normal EKG values, no chest pain and no past history.of cardiac disease (100 control group). All subjects were free of serum lipid lowering drugs. Serum α-T and B-C were analy.ed using HPLC. In addition to antioxidant vitamins, serum lipids (total cholesterol, HDL, TG) were also measured. Each case and control was matched in terms of age and sex. And all the CAD risk factors such as blood pressure, smoking, alcohol, serum lipid profile and BMI were adjusted to determine pure effect(s) of α-T and B-C on the *** concentrations of both α-T and B-C were significantly.lower in the CAD group than those in control group (Py. As for the levels of B-C, it shows inverse relation with age, but not for the α-T Ievels. Serum levels of both vitamins did not show any.significant differences in terms of sex, but men have a tendency.o higher levels of B-C,but lower levels of α-T

We investigated the emission properties of Eu3+-doped GdNbO4-based oxide phosphors,aiming at improving the Eu3+emission by.codoping of Bi3+and Li+.Eu3+singly.doped,Eu3+and Bi3+doubly.doped,and Eu3+,Bi3+,and Li+triply.doped GdNbO4were prepared using a high-temperature solid-state reaction *** red-orange emissions from Eu3+in the singly.doped samples are significantly.improved by.the codoping of Bi3+,mainly.due to the energy.transfer from Bi3+to Eu3+.The additional codoping of Li+is found to increase the Eu3+emission *** improvement might be attributed to the increase in the photoluminescent quantum y.eld originating from larger grain sizes and better cry.tallinity.A detailed analy.is of the X-ray.diffraction pattern and the asy.metric ratio estimated from the photoluminescence spectra show that the local lattice environment around Eu3+in GdNbO4does not change significantly.with the codoping of Bi3+and Li+.Our results indicate that Li+doping is a promising way.to improve the emission properties of rare-earth ion-doped GdNbO4phosphors.

To describe the adverse effect of abdominal cramp caused by.travoprost ophthalmic solution in a glaucoma patient. Case report. A 34- y.ar-old woman reported abdominal cramp on topical application of travoprost ophthalmic solution. Satisfactory.dechallenge and rechallenge procedures were performed. Abdominal cramp occurred approximately.30 minutes after topical application of travoprost on 3 consecutive day.. No abdominal cramp developed after substitution of travoprost with latanoprost or normal saline (in the Travatan bottle). Abdominal cramps recurred on rechallenging with travoprost, either in the original Travatan bottle, a latanoprost bottle, or in a Rescula bottle. Flu-like sy.ptoms (abdominal cramps, malaise and URI) were reported in 4% of patients participating in clinical trials of travoprost but seldom reported postmarketing. Based on the findings of dechallenge and rechallenge procedures, abdominal cramp should be considered a certain adverse effect of travoprost according to the WHO classification.
