In recent years, popularity of radiofrequency (RF) has increased significantly. They are characterized by a low risk of complications and relatively high effectiveness. RF use high-frequency currents causing oscillating motion of ions resulting in temperature rise stimulating skin regeneration processes. The aim of this work was the thermographic evaluation of the skin exposed to RF of different intensity. The dynamic thermal imaging was used to study the temperature of the skin exposed to RF. The research was carried out in two locations with different adipose tissue content: abdomen (ROI1) and forearm (ROI2). In the ROI1 area, RF was applied at nominal power range from 250 to 1750 W, while in ROI2 area: from 250 to 1000 W. The obtained thermographic data were fitted to exponential functions. A clear dependence of obtained thermokinetic parameters with the anatomical location of exposure to RF was demonstrated. Thicker layer of adipose tissue directly under the skin resulted in obtaining higher maximum temperatures of the skin surface during the procedure (maximum obtained temperature equaled 40.8°C). The temperature of the skin under the head of the device does not translate to subjective patient experiences. In anatomic locations filled with less adipose tissue mass, tolerance to RF is much lower. The dynamics of skin temperature changes, after the RF treatment, can be described by means of a single exponential function where the key parameter is the time constant t defining the dynamics of skin temperature changes. The depth of the RF influence is slightly correlated with the RF power.
Ostatnie badania potwierdzają prozdrowotne właściwości czekolady, chociaż historia kakao jako leku sięga kilku tysięcy lat. Drzewo kakaowca rosnące w klimacie równikowym, w wierzeniach starożytnych Majów i Azteków, było boskim darem dla ludzkości zapewniającym mądrość i wiedzę uniwersalną. Z jego ziaren uzyskiwany jest proszek kakaowy służący do produkcji czekolady zawierającej wiele składników bioaktywnych, w tym witaminy, składniki mineralne, polifenole i kwasy tłuszczowe. Czekolada pozytywnie wpływa na nastrój, zmniejsza podatność na stany depresyjne oraz stres oksydacyjny. Spożycie czekolady w trakcie ciąży może poprawić stan psychiczny przyszłych matek i zmniejszyć negatywny wpływ matczynego stresu na niemowlę. Dzięki wysokiej zawartości flawanoli wykazuje właściwości przeciwzapalne, przeciwalergiczne, przeciwwirusowe oraz przeciwnowotworowe. Pozytywnie wpływa na pamięć i umiejętności poznawcze, może zmniejszyć ryzyko demencji. Regularne spożywanie produktów zawierających kakao zmniejsza ryzyko zgonu z przyczyn sercowo-naczyniowych, a zwłaszcza udaru mózgu, oraz może zmniejszyć obwodową oporność na insulinę u kobiet z cukrzycą typu 2. Działa pobudzająco po wysiłku psychicznym lub fizycznym. Zapewnia uczucie sytości, dlatego była dodawana do żołnierskich racji żywnościowych w czasie I wojny światowej. Należy jednak pamiętać, że spożycie czekolady podnosi poziom kwasu szczawianowego w moczu oraz może prowadzić do zaostrzenia objawów trądziku pospolitego. Jest toksyczna dla zwierząt. Czekolada zawiera również związki, których znaczenie dla zdrowia nie zostało szczegółowo poznane.

However, the history of cocoa as a drug dates back several thousand years. The cocoa tree growing in the equatorial climate in the beliefs of the ancient Maya and Aztecs was a divine gift for humanity providing wisdom and universal knowledge. From its grains, cocoa powder is obtained for the production of chocolate, which contains many bioactive components, including vitamins, minerals, polyphenols
Background:Most of people suffering from both depression and sleep disturbances often require a specialist treatment. Depression and accompanying sleep disorders are a significant problems in society which need attention.Aims:The main aim of the study is showing the correlation between the extent of depression and the intensification of sleep disorders in its course.Methods:A group of 33 patients with diagnosed depression was examined, 20 women aged 39-68 and 13 men aged 47-63. The whole group was examined considering the period of the last month of patients’ life before starting taking medicaments. In the carried out research Beck Scale was used to estimate the extent of depression whereas Athens Insomnia Scale is utilized for describing the intensification of sleep disturbances.Results:In the group of men the average score of Beck's depression was 27,2 while the average score in insomnia scale was 16. In the group of women the following average scores were received, 32 in the Beck Scale and 14,17 in the Insomnia Scale. In order to show the extent of correlation between depression and sleep disorders the Spearman's coefficient of correlation was calculated and amounted to 0,27.Conclusions:According to received results along with increase of the extent of the depression there is a slight increase of the intensification of sleep disorders. The research is still ongoing with the target group of 100 examined patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
