SARS-CoV-2 antibody changes in patients receiving COVID-19 convalescent plasma from normal and vaccinated donors.

Vaccination has been shown to stimulate remarkably high antibody levels in donors who have recovered from COVID-19. Our objective was to measure patient antibody levels before and after transfusion with COVID-19 Convalescent Plasma (CCP) and compare the antibody levels following transfusion of CCP from vaccinated and nonvaccinated donors. Plasma samples before and after transfusion were obtained from 25 recipients of CCP and COVID-19 antibody levels measured.

Retinal nitric oxide and malonyldialdehyde levels following photodynamic therapy.

Background: To determine the retinal nitric oxide (NO) and malonyldialdehyde (MDA) levels following photodynamic therapy (PDT).

Materials And Methods: Seven Dutch-belted rabbits received dextrose, while seven others received 2 mg/kg verteporfin infusion over a period of 15 minutes in a dim-lit room. Irradiation to a 1.

The protective role of Visudyne eyeglass against VEGF synthesis after photodynamic therapy with verteporfin.

Purpose: We aimed to determine the extent of protection provided by Visudyne eyeglass against vascular endothelial growth factor (VEGF) synthesis following photodynamic therapy (PDT).

Methods: Three groups with 14 rabbits in each were established. These consisted of a control (dextrose infusion) group, an infusion (verteporfin infusion) group and an irradiation (verteporfin infusion + irradiation) group.

Phthriasis palpebrarum mimicking lid eczema and blepharitis.

Phthiriasis palpebrarum (PP) is a rare eyelid infestation caused by phthirus pubis. We report a case of PP mimicking lid eczema and blepharitis. A 68-year-old woman had moderate itching in both eyes.

Interplay of PDZ and protease domain of DegP ensures efficient elimination of misfolded proteins.

Aberrant proteins represent an extreme hazard to cells. Therefore, molecular chaperones and proteases have to carry out protein quality control in each cellular compartment. In contrast to the ATP-dependent cytosolic proteases and chaperones, the molecular mechanisms of extracytosolic factors are largely unknown.

Presumed nasolacrimal endometriosis.

A 13-year-old girl was admitted with a complaint of cyclic bleeding from the left inferior punctum with menstruation. Crusted hemorrhage was noticed in the tear meniscus of the left eye and just inferior to the left caruncle. With gradient-echo magnetic resonance imaging, the hemorrhagic tissue in the nasolacrimal canal was demonstrated and the diagnosis of nasolacrimal endometriosis was made.

The effect of photodynamic therapy on retrobulbar blood flow parameters.

Purpose: To investigate the effect of photodynamic therapy (PDT) on retrobulbar blood flow parameters.

Methods: Twenty-four patients with choroidal neovascular membrane of at least four MPS disc area in one eye due to age-related macular degeneration scheduled for PDT were recruited. Peak systolic and end diastolic velocity of ophthalmic, central retinal and posterior ciliary artery of both eyes were measured with colour Doppler imaging and resistivity index were computed before, at the first and fourth weeks following PDT.

Coats-like retinitis pigmentosa: Reports of three cases.

Purpose: Describing the ophthalmic findings of an exudative vasculopathy called as Coats-like retinitis pigmentosa on three patients. The etiology of the Coats-like retinitis pigmentosa is obscure. The principal theories have been discussed in this article.

Brain-derived neurotrophic factor and neurotrophin-3 levels in Alzheimer's disease brains.

In the present study, we investigated the levels of brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3) in post-mortem brain tissue of Alzheimer's disease (AD) patients, and we observed a significant increase of BDNF concentration in hippocampus and parietal cortex of AD patients, as well as a negative correlation between NT-3 levels and age in hippocampus and putamen of control subjects, and for BDNF in frontal cortex. A defining feature of AD is the post-mortem identification of neuritic plaques and neurofibrillary tangles in the brain, however, a more significant neuropathological finding is the degeneration of cholinergic neurones of the basal forebrain, critically involved in memory and cognition. Neurotrophic factors are partly responsible for the maintenance of neuronal function and structural integrity in the adult brain.

Stalking as a variant of domestic violence.

Much of what is presently known about stalking in a domestic context has been depicted by the popular press, typically following a tragic outcome, and suggests that it is a problem of increasing dimensions. However, scientific literature on this subject is quite limited. This article provides an overview of scientific data related to stalking and associated psychiatric syndromes, including erotomania.

Dual expression of CD45RA and CD45RO isoforms on myelin basic protein-specific CD4+ T-cell lines in multiple sclerosis.

Myelin basic protein (MBP)-specific T-cell lines from patients with multiple sclerosis (MS) and healthy controls were analyzed for the expression of CD45 isoforms and adhesion molecules. In the multiple sclerosis group, 22 of 24 MBP-specific T-cell lines were CD4+. Two distinct patterns were observed with regard to CD45 isoform expression.

[Health status and management of elderly citizens of a residential district and a home for the aged in the city of Erfurt].

Preservation, furtherance and recovery of health and great joy the old age - these are requests of social politics in GDR. The ageing may be influenced by a series of sanitary and social factors of risk. We have examined 100 townsmen in a home for aged people and 100 pensioners in housing-settlement of Erfurttown.
