Favorable outcome of Lasiodiplodia theobromae keratomycosis : a clinical case and systematic review.

Backroud: Keratitis caused by Lasiodiplodia theobromae is rare and typically associated with a poor prognosis. Current literature lacks sufficient evidence on effective management of patients with this condition.

Case Presentation: A 74-year-old former agricultural worker presented with a red right eye, discomfort, and decreased visual acuity, progressing over three days without treatment.

The table maneuver: a procedure used with success in four cases of unconscious choking older subjects.

Background: confronted with an unconscious choking victim, it is recommended to call an ambulance and start mouth-to-mouth and cardiopulmonary resuscitation (CPR). We describe a procedure called the "table maneuver" that was successful in relieving foreign-body airway obstruction in 4 cases of choking in unconscious elderly patients over a 6-year period in the same long-term care facility.

Methods: the patients ranged in age from 70 to 89 years and were cyanosed and unconscious after choking while having a meal at a table.

The effect of skull-pin insertion on cerebrospinal fluid pressure and cerebral perfusion pressure: influence of sufentanil and fentanyl.

This randomized prospective study measured the effects of an intravenous opioid bolus on cerebrospinal fluid pressure (CSFP), mean arterial pressure (MAP), and cerebral perfusion pressure (CPP) during skull-pin insertion. Twenty-two adult patients scheduled for elective craniotomy for supratentorial lesions were studied. Outcome variables were MAP, heart rate (HR), and lumbar CSFP.

Involvement of the Ca(2+)-dependent phosphorylation of a 20 kDa protein in the proliferative effect of high-density lipoproteins (subclass 3) on the adenocarcinoma cell line A549.

Previous studies from our laboratory demonstrated that high-density lipoproteins (subclass 3; HDL3) bind to sites specific for apolipoprotein AI on the human adenocarcinoma cell line A549 and that HDL3 binding promotes a mitogenic effect [Favre, Tazi, Le Gaillard, Bennis, Hachem and Soula (1993) J. Lipid Res. 34, 1093-1106].

Model systems for oxidative drug metabolism studies. Catalytic behavior of water-soluble metalloporphyrins depends on both the intrinsic robustness of the catalyst and the nature of substrates.

Sulfonated manganese and iron porphyrins have been used as catalysts in attempts to mimick the oxidation of acetaminophen and two ellipticine derivatives by horseradish peroxidase. Cofactors were potassium monopersulfate for the synthetic catalyst and hydrogen peroxide for the natural enzyme. Hindered metalloporphyrins, i.

Model systems for metabolism studies. Biomimetic oxidation of acetaminophen and ellipticine derivatives with water-soluble metalloporphyrins associated to potassium monopersulfate.

Some original water-soluble metalloporphyrins/KHSO5 systems were developed to mimic the metabolic biooxidation of drugs. Oxidation of acetaminophen and various ellipticine derivatives were used as model reactions. Oxidative products (mainly quinone-imine structures) were obtained in good yield after 2 min of reaction, for a catalyst/substrate ratio of 0.

Synthesis and anthelminthic evaluation of 2-amidino-1,3,4-oxa and 1,3,4-thiadiazoles, structurally related to tetramisole.

N-(1,3,4-thiadiazol-2-yl) 1a-1k and N-(1,3,4-oxadiazol-2-yl-) amidines 2a-2g, N-(1,3-thiazol-2-yl) 3a, 3b and N-(1,3-benzothiazol-2-yl-)amidines 4a, 4b were synthesized and tested as anthelminthics, in vitro, against a free nematode (Rhabditis pseudoelongata), against infecting larvae of an intestinal parasite of rats (Nippostrongylus brasiliensis) and against infecting larvae of a filaria (Molinema dessetae).

[Dihydro-5,6-imidazo[2,1-b]thiazoles, dihydro-2,3-imidazo[2,1-b]benzothiazoles, analogs of levamisole].

New compounds containing 5,6-dihydro imidazo[2,1-b]thiazole, 2,3,5,6-tetrahydro imidazo[2,1-b]thiazole and 2,3-dihydro imidazo[2,1-b]benzothiazole rings, substituted by heterocycles analogue to chromones, were synthesized and screened against three nematodes, in vitro. The results indicate moderate anthelmintic properties, compared to levamisole; nevertheless, some products exhibit a significant degree of activity.

The biooxidation of cytotoxic ellipticine derivatives: a key to structure-activity relationship studies?

In the family of ellipticine derivatives, those with an amino-phenol or a masked amino-phenol structure are among the most cytotoxic compounds. Preliminary studies on 9-hydroxy- or 9-methoxyellipticines have shown that these molecules behave as "pro-alkylating" agents. In order to rationalize the "biooxidative alkylation" process for various ellipticine derivatives, we report in the present article (i) their electrochemical oxidation parameters, (ii) their biochemical oxidation, (iii) the ability of the oxidized forms to form adducts with nucleophiles, (iv) the biological activities, and (v) the electronic properties of oxidized forms.
