Cost comparison of commonly used postoperative topical ophthalmic antibiotics.

Purpose: To provide information on the actual fill level and cost of currently available antibiotic drops used perioperatively.

Design: Prospective laboratory investigation.

Setting: Robert Cizik Eye Clinic, Houston, Texas USA.

Sixteen-year experience with the Putterman-Gladstone tube for conjunctival dacryocystorhinostomy.

Purpose: To determine whether the Putterman-Gladstone tube is a safe and effective lacrimal bypass tube in conjunctival dacryocystorhinostomy surgery.

Methods: The authors retrospectively reviewed the charts of patients who underwent conjunctival dacryocystorhinostomy with the Putterman-Gladstone tube between January 1994 and December 2010. Clinical data reviewed included demographics, ocular and surgical history, epiphora symptoms, complications, and repeat surgery information.

Comparison of an indirect immunofluorescence assay, western blot analysis, and a commercially available ELISA for detection of Ehrlichia canis antibodies in canine sera.

Objective: To examine the correlation between results for an indirect immunofluorescence assay (IFA) that uses Ehrlichia canis antigen as a substrate (ie, E canis-IFA), 2 western blot (WB) analyses, and a commercially available ELISA in the detection of E canis antibody in dog sera.

Sample Population: 54 canine serum samples that were reactive on E canis-IFA and 16 canine serum samples that were E canis-IFA nonreactive.

Procedure: Serum samples were evaluated by use of 2 WB analyses and a commercially available ELISA.

Two novel strains of Bacillus thuringiensis toxic to coleopterans.

Two novel strains of Bacillus thuringiensis were isolated from native habitats by the use of genes coding for proteins toxic to coleopterans (cryIII genes) as hybridization probes. Strain EG2838 (isolated by the use of the cryIIIA probe) contained a cryIIIA-hybridizing plasmid of approximately 100 MDa and synthesized crystal proteins of approximately 200 (doublet), 74, 70, 32, and 28 kDa. Strain EG4961 (isolated by the use of a cryIIIA-related probe) contained a cryIIIA-hybridizing plasmid of approximately 95 MDa and synthesized crystal proteins of 74, 70, and 30 kDa.

Amino acid sequence and entomocidal activity of the P2 crystal protein. An insect toxin from Bacillus thuringiensis var. kurstaki.

The gene encoding the 66-kDa entomocidal protein (P2 protein or mosquito factor) from Bacillus thuringiensis var. kurstaki has been isolated by the use of a 62-mer oligonucleotide probe that encoded 21 amino acids of the P2 protein NH2 terminus. The DNA sequence of the gene, designated cryBI, was unique from the published sequences of other B.

Starvation proteins in Escherichia coli: kinetics of synthesis and role in starvation survival.

Starvation proteins synthesized by Escherichia coli at the onset of carbon starvation (R. G. Groat and A.

A placebo-controlled, double-blind trial of amitriptyline in bulimia.

Bulimia is an eating disorder characterized by a pattern of episodic binge-eating. Patients with this eating disorder frequently demonstrate depressive symptoms when seen for evaluation. A familial association between bulimia and affective disorders has also been suggested.

Isolation and Immunochemical Characterization of Plant Glutamine Synthetase in Alfalfa (Medicago sativa L.) Nodules.

Host plant glutamine synthetase (GS) has been purified 100-fold from N(2)-fixing alfalfa (Medicago sativa L.) nodules by a new procedure involving preparative sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) as a final step. An SDS-polypeptide fraction corresponding to plant GS was identified and consisted of two major polypeptides of 40,000 to 45,000 molecular weight.

Root and Nodule Enzymes of Ammonia Assimilation in Two Plant-Conditioned Symbiotically Ineffective Genotypes of Alfalfa (Medicago sativa L.).

Biochemical and physiological parameters associated with nitrogen metabolism were measured in nodules and roots of glasshouse-grown clones of two symbiotically ineffective alfalfa (Medicago sativa L.) genotypes supplied with either NO(3) (-) or NH(4) (+). Significant differences were observed between genotypes for nodule soluble protein concentrations and glutamine synthetase (GS) and glutamate synthase (GOGAT) specific activities, both in untreated controls and in response to applied N.

Root Nodule Enzymes of Ammonia Assimilation in Alfalfa (Medicago sativa L.) : DEVELOPMENTAL PATTERNS AND RESPONSE TO APPLIED NITROGEN.

Nitrogenase-dependent acetylene reduction activity of glasshouse-grown alfalfa (Medicago sativa L.) decreased rapidly in response both to harvesting (80% shoot removal) and applied NO(3) (-) at 40 and 80 kilograms N per hectare. Acetylene reduction activity of harvested plants grown on 0 kilogram N per hectare began to recover by day 15 as shoot regrowth became significant.

The appearance of mania following intravenous calcium replacement.

The appearance of mania in a 35-year-old woman following the rapid intravenous correction of hypocalcemia is described. The importance of physiological fluctuations of serum calcium in affective modulation is stressed. Caution in speed of replacement of deficiency states is recommended.
