Extract from , , and Improves near Visual Acuity in People with Presbyopia.

Presbyopia is a global problem with an estimated 1.3 billion patients worldwide. In the area of functional food applications, dietary supplements or herbs, there are very few reports describing the positive effects of their use.

Effect of Drying Methods on Chemical and Sensory Properties of Leaves.

Hemp is used as a source of fiber, oil and bioactive substances including volatile and cannabinoid-containing substances. This paper presents, for the first time, results on the evaluation of drying methods (convective, vacuum-microwave and combined convective pre-drying and vacuum-microwave finishing drying) of hemp leaves on the qualitative and quantitative changes in secondary metabolites, including essential oils, cannabinoids and sterols. A ranking and descriptive test of hemp leaves was also performed.

The iridoid loganic acid and anthocyanins from the cornelian cherry (Cornus mas L.) fruit increase the plasma l-arginine/ADMA ratio and decrease levels of ADMA in rabbits fed a high-cholesterol diet.

Background: Although fruit and vegetable-rich diets have beneficial effects on cardiovascular diseases, we have little knowledge of the impact of fruits and their constituents, iridoids and anthocyanins, on the l-arginine-ADMA-DDAH pathway. Our previous study demonstrated the modulation of those factors by the oral administration of the cornelian cherry fruit.

Hypothesis/purpose: We have assessed the effects of the oral administration of two main constituents isolated from the cornelian cherry fruit, iridoid loganic acid and anthocyanins, on l-arginine, its derivatives (ADMA, SDMA), metabolites (DMA, l-citrulline), and the hepatic DDAH activity and its isoform expression in rabbits fed a high-cholesterol diet.

Loganic acid and anthocyanins from cornelian cherry (Cornus mas L.) fruits modulate diet-induced atherosclerosis and redox status in rabbits.

Background: Cornelian cherry (Cornus mas L.) is a plant growing in southeast Europe, in the past used in folk medicine. There are many previous publications showing the preventive effects of (poly)phenolic compounds, especially anthocyanins, on cardiovascular diseases, but there is a lack of studies comparing the effects of (poly)phenolics and other constituents of fruits.

Comparison of Visual Field Measurement with Heidelberg Edge Perimeter and Humphrey Visual Field Analyzer in Patients with Ocular Hypertension.

Background: Glaucoma is a group of eye diseases which result in damage to the optic nerve and vision loss. The most important examination in glaucoma patients is visual field assessment. One of the newer perimeters is Heidelberg Edge Perimeter (HEP).

Iridoid-loganic acid versus anthocyanins from the Cornus mas fruits (cornelian cherry): Common and different effects on diet-induced atherosclerosis, PPARs expression and inflammation.

Background And Aims: Cardiovascular benefits of fruits are attributed mainly to their (poly)phenolic constituents, especially anthocyanins. The main aim of our study is to compare effects of iridoids and anthocyanins from one fruit on diet-induced atherosclerosis. The cornelian cherry is a native or cultivated plant that grows in many European countries, used in cuisine and folk medicine.

Heidelberg Edge Perimeter: The New Method of Perimetry.

Glaucoma is an optic nerve neuropathy associated with progressive visual field loss. One of the most frequent eye diseases these days, it is believed to have affected 60 million people worldwide in 2014. Various visual field examination methods are known, from the confrontational test to kinetic and static perimetry.

Application of Cornelian Cherry Iridoid-Polyphenolic Fraction and Loganic Acid to Reduce Intraocular Pressure.

One of the most common diseases of old age in modern societies is glaucoma. It is strongly connected with increased intraocular pressure (IOP) and could permanently damage vision in the affected eye. As there are only a limited number of chemical compounds that can decrease IOP as well as blood flow in eye vessels, the up-to-date investigation of new molecules is important.

The influence of new beta-adrenolytics nebivolol and carvedilol on intraocular pressure and iris blood flow in rabbits.

Background: The aim of this study was to assess the influence of propranolol, nebivolol, and carvedilol on intraocular pressure and blood flow in vessels of rabbit's (New Zealand White) eyeball.

Methods: The study was carried out on New Zealand white rabbits. Intraocular pressure was measured with the applanation tonometer Möller-Wedel and Icare; blood flow was measured with Doppler Laser Blood Flow Monitor MBD3.

Heidelberg edge perimeter employment in glaucoma diagnosis--preliminary report.

In recent years, the authors have seen huge progress in the diagnosis of eye diseases. One of the new diagnostic devices is HEP (Heidelberg Edge Perimeter) - for early diagnosis of glaucoma and its progression. It combines visual field test and HRT (Heidelberg Retina Tomograph), which allows authors to obtain the image of the mutual relation between the structure and the function of the sight organ.
