In this investigation, we study the synthesis and the evaluation of antioxidant and hypocholesterolemic activity of a number of 2-biphenylyl morpholine derivatives, which are structurally similar to some substituted morpholines possessing antioxidant activity, as well as to hypocholesterolemic 3-biaryl-quinuclidines. The novel derivatives are found to inhibit the ferrous/ascorbate induced lipid peroxidation of microsomal membrane lipids, the most potent derivative, 2-(4-biphenyl)-4-methyl-octahydro-1,4-benzoxazin-2-ol (compound 7), having an IC(50) value of 250 microM. In addition, these compounds demonstrate hypocholesterolemic and hypolipidemic action.

Background: Systemically-administered tetracyclines have been used widely for treatment of periodontal diseases with little understanding of their delivery characteristics to periodontal tissues. This study was designed to measure concentrations of 3 tetracyclines in gingival crevice fluid (GCF), plasma and saliva of following systemic administration.

Method: The concentration of tetracycline (TC), minocycline (MN) and doxycycline (DX) was measured in gingival crevice fluid (GCF), plasma and saliva of 20 subjects following single sequential standard oral systemic doses.

We studied 27 patients with stable chronic obstuctive pulmonary disease (COPD) in a randomised, single-blind, within-patient, placebo-controlled clinical study. Each patient was assigned on six separate days to receive one of the following drug regimens in random order: A. 40 micrograms ipratropium bromide (Atrovent MDI, 20 micrograms/puff) plus 2 puffs placebo; B.

This case study reports detailed phantom sensations in a 35-yr.-old man who had his C5 and C6 cervical nerve roots avulsed from the cord during a motorcycle accident at the age of 22 years. The subject, who was left with a paralyzed right deltoid muscle, anesthetic sensation along the upper lateral portion of the right arm, and absent right biceps reflex, became aware of phantom right arm and hand sensations a few months after the original injury.

Complications after vertical gastroplasty with artificial pseudopylorus in the treatment of morbid obesity: a 7-year experience.

Obes Surg

December 1999

Aristotelian University of Thessaloniki, 3rd Surgical Department, AHEPA Hospital, Macedonia, Greece.

Background: Vertical gastroplasty with artificial pseudopylorus (VGAP) was designed to reduce the complication rate of other forms of gastroplasty. The purpose of this study was to analyze the complications of this approach for 7 years of surgical practice.

Methods: A total of 156 morbidly obese patients (BMI 41-81 kg/m2) who underwent VGAP were analyzed retrospectively in terms of early and late complications and gastroplasty failure.

Psychiatric comorbidity in Greek patients with generalized anxiety disorder.

Psychopathology

January 2000

Community Mental Health Center, Northwestern District of Thessaloniki, and B' University Department of Psychiatry, Aristotelian University of Thessaloniki, Thessaloniki, Greece.

From a total sample of 1,448 psychiatric outpatients, 81 (5.6%) received a diagnosis of generalized anxiety disorder (GAD) according to DSM-III-R criteria. Fifty-three (65%) of them had another Axis I diagnosis, while this percentage increased to 78% (63/81) when lifetime psychiatric diagnoses were recorded.

Polycystic ovary syndrome (PCOS) is characterized by its heterogeneity. This is the reason for the diversity in the clinical manifestations and laboratory findings. In this study we examined the serum levels of growth hormone (GH) in 15 women with PCOS and 5 healthy volunteers following oral administration of 75 gr glucose (OGTT) and intravenous administration of insulin (ITT).

Arginine/serine protein kinases constitute a novel class of enzymes that can modify arginine/serine (RS) dipeptide motifs. SR splicing factors that are essential for pre-mRNA splicing are among the best characterized proteins that contain RS domains. TwoSRprotein-specifickinases, SRPK1 and SRPK2, have been considered as highly specific for the phosphorylation of these proteins, thereby contributing to splicing regulation.

Background/aims: It has been shown that IL-2 and gamma-IFN own an additive immunostimulatory effect against tumors. Moreover, it has been suggested that the locoregional route of administration of immunopotentiating agents has substantial advantages compared to the systemic route. The aim of the present study was to evaluate the immune response of patients with advanced unresectable liver and pancreatic malignant disease who were submitted for transplenic and transtumoral IL-2 and gamma-IFN combination immunotherapy.

The purpose of this study was to evaluate the bone mineral density (BMD) of 50 patients aged 9-28 years, with thalassemia major and to assess the alterations of bone density in a 4-year follow-up study. They were measured with a DPX densitometer at the lumbar spine and femur area and divided into three groups: preadolescents, adolescents, and adults. All patients received calcium and vitamin D supplements, and 8 of the 50 received hormone replacement therapy (HRT).

SRPK1 and LBR protein kinases show identical substrate specificities.

Biochem Biophys Res Commun

February 1999

Laboratory of Biochemistry, School of Chemistry, Aristotelian University of Thessaloniki, Thessaloniki, 54 006, Greece.

Arginine/serine protein kinases constitute a novel class of enzymes that can modify arginine/serine (RS) dipeptide motifs. SR splicing factors that are essential for pre-mRNA splicing and the lamin B receptor (LBR), an integral protein of the inner nuclear membrane, are among the best characterized proteins that contain RS domains. Two SR Protein-specific Kinases, SRPK1 and SRPK2, have been shown to phosphorylate specifically the RS motifs of the SR family of splicing factors and play an important role in regulating both the spliceosome assembly and their intranuclear distribution, whereas an LBR-associated kinase, that specifically phosphorylates a stretch of RS repeats located at the NH2-terminal region of LBR, has been recently purified and characterized from turkey erythrocyte nuclear envelopes.

Thirty outpatients meeting DSM-III-R or DSM-IV criteria for major depression, single or recurrent episode, and failing to respond to an adequate trial of an antidepressant (>6 weeks at recommended dosage) received buspirone (20-30 mg/day) for 4 or 5 weeks in addition to their existing antidepressant. Of the 22 patients who had buspirone added to their selective serotonin reuptake inhibitor antidepressant regimen (fluoxetine, paroxetine, or citalopram), 59% (13/22) showed complete or partial remission of their depressive symptomatology. Similarly, 63% (5/8) of patients treated with buspirone in addition to clomipramine showed complete or partial remission.
