The Polish women's experience and level of knowledge about fertility and its disorders - a cross-sectional study.

Objectives: To assess the experience and knowledge of Polish women up to 50 years of age about fertility and its disorders.

Material And Methods: A self-composed questionnaire consisting of 44 questions, divided into six sections, was available in social media from January until February 2020. The answers to 13 single-choice questions were analyzed to assess the level of knowledge.

[The safety and tolerance of isoflavones (Soyfem) administration in postmenopausal women].

Introduction: In recent years, considerable attention has been paid to isoflavones and their proprieties to alleviate the climacteric symptoms. The goal of this study was to evaluate the efficacy of standardized isoflavones extract (Soyfem) in moderate and medium-severe climacteric syndrome.

Material And Methods: 555 postmenopausal women were recruited for the study.

Influence of exercise induced hyperlactatemia on retinal blood flow during normo- and hyperglycemia.

Purpose: Short term hyperglycemia has previously been shown to induce a blood flow increase in the retina. The mechanism behind this effect is poorly understood. We set out to investigate whether exercise-induced hyperlactatemia may alter the response of retinal blood flow to hyperglycemia.

Changes in choroidal blood flow during light/dark transitions are not altered by atropine or propranolol in healthy subjects.

It has recently been reported that light/dark transitions lead to changes in choroidal blood flow. Several observations indicate that these changes in choroidal perfusion are triggered at least in part by neural mechanisms. In the present study we hypothesised that the choroidal blood flow response to changes in retinal illumination may be modified by either the muscarinic receptor antagonist atropine or by the beta-receptor antagonist propranolol.

Role of endothelin-1 in choroidal blood flow regulation during isometric exercise in healthy humans.

Purpose: There is evidence that the choroid has some autoregulatory capacity in response to changes in ocular perfusion pressure (OPP). The mediators of this response are hitherto unidentified. The hypothesis for the current study was that endothelin (ET)-1 and/or angiotensin (ANF)-II may be involved in choroidal vasoconstriction during an increase in OPP.

Effects of granulocyte colony stimulating factor on retinal leukocyte and erythrocyte flux in the human retina.

Purpose: The blue-field entoptic technique was introduced more than 20 years ago to quantify perimacular white blood cell flux. However, a final confirmation that the perceived corpuscles represent leukocytes is still unavailable.

Methods: The study design was randomized, placebo-controlled, and double masked with two parallel groups.
