The association between glycemic control and clinical outcomes after kidney transplantation.

Objective: To analyze the relationship between glycemic control after renal transplantation and subsequent graft function and complications.

Methods: We conducted a retrospective chart review of 202 consecutive patients undergoing kidney transplantation to analyze the association between perioperative and chronic glycemic control and clinical outcomes of rejection, infection, and hospital readmission during the first year after kidney transplantation.

Results: Mean in-hospital blood glucose (BG) was 157 ± 34.

Relationship between glycated hemoglobin and circulating 25-hydroxyvitamin D concentration in African American and Caucasian American men.

Objectives: To examine whether (1) serum 25-hydroxyvitamin D level (25[OH]D) is a risk factor for hyperglycemia, as assessed by glycated hemoglobin (HbA1c), in African American men (AAM) and (2) 25(OH)D is a predictor of HbA1c in AAM and Caucasian American men (CAM).

Methods: We prospectively assessed 25(OH)D and HbA1c in 1,074 men, outpatients with and without diabetes, at an urban Veteran Administration Medical Center (66.8% AAM, 26.

Early life stress differentially modulates distinct forms of brain plasticity in young and adult mice.

Background: Early life trauma is an important risk factor for many psychiatric and somatic disorders in adulthood. As a growing body of evidence suggests that brain plasticity is disturbed in affective disorders, we examined the short-term and remote effects of early life stress on different forms of brain plasticity.

Methodology/principal Findings: Mice were subjected to early deprivation by individually separating pups from their dam in the first two weeks after birth.

Sorption studies of chromium(VI) onto new ion exchanger with tertiary amine, quaternary ammonium and ketone groups.

A new acrylic anion exchanger with both tertiary and quaternary ammonium as well as ketone groups in the structural unit has been prepared by the nucleophilic substitution reaction of aminolyzed vinylacetate:acrylonitrile:divinylbenzene copolymer of porosity structure in the swelling state with 2-chloroacetone as a halogenated compound. The new compound exhibits better qualities of strong base exchange capacity than the weak base anion exchangers. The obtained acrylic anion exchanger was used to remove Cr(VI) from the aqueous solution.

Determination of glutation peroxidase and superoxide dismutase activities in canine seminal plasma and its relation with sperm quality and lipid peroxidation post thaw.

Lipid peroxidation (LPO) of dog spermatozoa was assessed in fresh semen and in samples of the same ejaculates after freezing and thawing. Particular attention was paid to individual differences in the susceptibility to LPO and its possible relationship with freezeability. Innate levels of LPO were low in fresh spermatozoa but increased after thawing in one of the dogs included in our study.

Removal of hexavalent chromium by new quaternized crosslinked poly(4-vinylpyridines).

New quaternized crosslinked poly(4-vinylpyridines) prepared by nucleophilic substitution reactions of 4-vinylpyridine: divinylbenzene copolymers of gel and porous structure with halogenated compounds such as benzyl chloride and 2-chloracetone, were used to remove Cr(VI) from the aqueous solution. Batch adsorption studies were carried out to determine the effect of the initial concentration of Cr(VI), pH, temperature and the presence of sulfate anions. The process was found to be pH and concentration dependent.

Freezing dog semen in presence of the antioxidant butylated hydroxytoluene improves postthaw sperm membrane integrity.

In an attempt to evaluate the protective effect of a lipid-soluble antioxidant (butylated hydroxytoluene; BHT), semen from four dogs (Canis familiaris) was frozen in two different extenders (Uppsala or INRA-96 plus glycerol) with or without 1mM BHT. Sperm membrane integrity using flow cytometry and motility using a computerized system were evaluated in each experimental group. The Uppsala extender was superior in all aspects of sperm function.

Platinum (IV) recovery from chloride solution by functionalized acrylic copolymers.

Two acrylic adsorbents with different morphological structures and bearing amidoethylenamine and thiol groups were obtained and used for platinum sorption from chloride solution by the batch method. Physico-chemical parameters that influence adsorption such as initial Pt(IV) concentration, stirring time, pH, and adsorbent amount were investigated. The thermodynamic parameters of Pt(IV) sorption on the synthesized adsorbent were also evaluated based on Langmuir and Freundlich isotherms.

Removal of Cr(VI) onto functionalized pyridine copolymer with amide groups.

New pyridine strong base anion exchange resin has been prepared by the nucleophilic substitution reaction of 4-vinylpyridine:divinylbenzene copolymer of gel structure with 2-chloroacetamide as halogenated compound. The resulting resin was used to remove Cr(VI) from the aqueous solution. Batch adsorption studies have been carried out to determine the effect of the initial concentration of Cr(VI), adsorbent dose, pH, temperature and the presence of sulfate anions as counter ions.

Potential anticancer agents. XXII. Pharmacological properties of some new triazene derivatives.

The pharmacological properties (toxicity and antitumor activity against W256 carcinosarcoma and L1210 leukemia) of thirty five new triazenes derived both from amides and esters of 3-methyl-4-amino-benzoic acid and from aromatic dipeptidic esters were investigated. The new compounds proved to be moderately effective against W256 carcinosarcoma and totally devoid of activity against L1210 leukemia, except for ethyl,4-(3,3-dimethyltriazenophenyl)-N-alpha-(9-fluorenyl)-acetyl-L-alanine ester which exhibited borderline activity against this leukemia. The pharmacological data thus obtained were correlated with the physico-chemical parameters of the new triazenes in a quantitative structure-activity relationship (QSAR approach).

Urinary lithiasis associated with urinary tuberculosis.

In a series of 2,500 patients with urinary tuberculosis, 74 cases evidenced an associated lithiasis (2.96%). Intensifying and amplifying the noxious effects, the association of these affections is misleading.

Juxtavesical hydatid cysts.

Out of 177 different hydatid localisations 9 were juxtavesical. In 3 patients the cysts were recurrent. The diagnosis, based on the clinical and radiological examinations and exploration was facilitated by the history or the co-existence of other parasitic lesions.

Improved suprapubic vesical drainage in transvesical prostatectomy.

An improved drainage is used in transvesical prostatectomy in order to avoid urinary retention after removal of the Novak-type suprapubic drainage with bladder neck cerclage haemostasis (described by some authors in 1975). The causes of urinary retention are analysed, the drainage technique as well as the mechanisms eliminating the above-mentioned complications are described.
