Opis:
Age-related macular degeneration (AMD), glaucoma and cataracts are the most common eye diseases. They are predominantly caused by insufficient amounts of antioxidants in the body, which include lutein, zeaxanthin, lycopene, omega-3 fatty acids, vitamins and micronutrients. The positive properties of these biologically active substances affect the neutralization of reactive oxygen species, slow absorption of UV radiation, and improve blood supply to the structural elements of the eye. Deficiency of these substances has a negative effect on the functioning of the eye, leading to degeneration of its structures. Presently, a fully effective method of treatment has not been discovered, therefore preventative measures, especially those including a healthy diet and lifestyle, are highly important as the human body cannot synthesize these beneficial substances. This requires increasing public awareness concerning products with high nutritional value, which should be included in people's daily diet.

Opis:
The aim of the study was to assess the nutritional habits of AMD patients from the Szczecin region. Age-related macular degeneration (AMD) is a chronic, progressive eye disease that results in loss of central vision. The study was conducted in the Ophthalmology Clinic of the Independent Public Teaching Hospital No. 2, Pomeranian Medical University (PUM) in Szczecin among 46 subjects. The interview method was used using the author's questionnaire, which contained questions about age, body weight and height, sex, composition of the three-day menu and the form of AMD. Insufficient intake of numerous nutrients (with lutein and zeaxanthin among them) has been shown, which may accelerate the progression of the disease. In addition, patients were underweight, which may increase the risk of protein-energy malnutrition that may affect the development of AMD.

Toxicity test
Opis:
Cadmium wastewater released by human activities will eventually enter the aquatic environment. Living organism that lives around could potentially exposed by these cadmium, including C. gracilis which play a critical role as a primary producer. Cadmium can reduce the growth rate and pigment content in C. gracilis. Therefore, toxicity testing becomes important to do considering that C. gracilis has many benefits such as shrimp feed and have active compounds for antibacterial and biodiesel. Toxicity test was performed in 96-hours with a series of concentration 0, 0.56, 1.0, 1.8, 3.2, 5.6 mg/L. IC50 cadmium results in concentrated cell density and chlorophyll-a C. gracilis were 1.62 mg/L and 3.4 mg/L, while carotenoids were not in accordance with the contribution of cadmium. NOEC and cadmium LOEC to C. gracilis cell density were 0.56 mg/L and 1.0 mg/L.

Opis:
The objective of this study was to evaluate the nutritional value and the content of bioactive compounds in the fruit of individual species of chaenomeles and quince. The experimental material were the fruits of four species of chaenomeles (Chaenomeles×superba, Chaenomeles japonica apple-shape, Chaenomeles japonica pear-shape and Chaenomeles ssp.) and quince (Cydonia oblonga). The fruit were analyzed for dry matter, vitamin C, polyphenols, carotenoids and chlorophyll content. The obtained results showed that the species has an impact on the nutritional value and the content of bioactive compounds in the chaenomeles and quince fruits. The highest content of dry matter, total polyphenols, total phenolic acids as well as more total and individual phenolic acids (caffeic and p-coumaric acid) were found in quince fruits (Cydonia oblonga). Quince fruits Cydonia oblonga also contained the highest content of total flavonoids and individual flavonoids: quercetin-3-O-rutinoside, myrycetin and quercetin. The highest content of lutein and zeaxanthin was observed in fruits of Chaenomeles ×superba but Cydonia oblonga fruits contained significantly more beta-carotene and chlorophyll, both the total chlorophylls and individual chlorophylls: chlorophyll a and chlorophyll b. In contrast, the highest content of vitamin C was found in fruits Chaenomeles Japanese pear-shape.
