Gravity profiles interpretation applying a metaheuristic particle optimization algorithm of mineralized bodies resembled by finite elements.

The interpretation of gravity anomalies is crucial for identifying subsurface mineralized targets and understanding the density variations between the targets and the surrounding structures. To confirm the presence of ore and mineral targets, simple geometric bodies are often used. One of the commonly used global metaheuristic algorithms for gravity data analysis is the particle optimization algorithm.

[High-dose intravitreal ganciclovir in CMV retinitis].

Purpose: To assess the efficacy and tolerability of high-dose (2000microg) intravitreous ganciclovir in the maintenance therapy of CMV retinitis in AIDS patients.

Material: and methods: Prospective open study in a single center. The maintenance therapy of CMV retinitis consisted of a single high-dose (2000microg) intravitreous injection per week.

Uveitis in patients treated with intravenous cidofovir.

Purpose: To study the characteristics of uveitis occurring during intravenous cidofovir treatment for CMV retinitis in patients with AIDS.

Patients And Methods: We retrospectively studied ten cases (16 eyes) of uveitis in patients with CMV retinitis treated with intravenous cidofovir. All the patients had ophthalmologic examinations and, if required, fundus angiographies.

Epidemiological considerations about retinal opportunistic infections in HIV-infected patients in France.

Purpose: To evaluate the evolution of the epidemiology of retinal opportunistic infections in HIV-infected patients from 1994 to 1997 and to assess the effect of HAART initiated in 1996.

Materials And Methods: Epidemiological prospective study using the data collected during ocular examinations of HIV-infected patients conducted in a single referral center specialized in HIV infection.

Results: From 1995 to 1997, the total number of examined HIV-infected patients and the incidence of retinitis related to CMV, VZV, tuberculosis, and toxoplasmosis decreased.

Cytomegalovirus retinitis in HIV-infected patients with and without highly active antiretroviral therapy.

Purpose: To assess the impact of highly active antiretroviral therapy on the epidemiology of cytomegalovirus retinitis in patients infected with the human immunodeficiency virus (HIV).

Methods: In a study performed in a single center for infectious diseases, we compared the data collected in 1995 (without highly active antiretroviral therapy) with 1997 data (with highly active antiretroviral therapy).

Results: In a comparison of 1997 with 1995 data, the mean CD4+ cell count of patients with cytomegalovirus (CMV) retinitis was higher (169 +/- 150 CD4/microl vs 15 +/- 47 CD4/microl) (P = .

Antibody responses of mice exposed to low-power microwaves under combined, pulse-and-amplitude modulation.

Irradiation by pulsed microwaves (9.4 GHz, 1 microsecond pulses at 1,000/s), both with and without concurrent amplitude modulation (AM) by a sinusoid at discrete frequencies between 14 and 41 MHz, was assessed for effects on the immune system of Balb/C mice. The mice were immunized either by sheep red blood cells (SRBC) or by glutaric-anhydride conjugated bovine serum albumin (GA-BSA), then exposed to the microwaves at a low rms power density (30 microW/cm2; whole-body-averaged SAR approximately 0.

[Iridociliary melanoma with cataract (iridocyclochoroidectomy followed by extra-capsular extraction with pseudophakia)].

Description of a case of malignant melanoma of iris and ciliary body in a man of 59 years old. Clinically an interesting sign was the mahogany discolouration of the greyish cataract in the quadrant in front of the tumour. The tumour was removed following the technic of H.
