Introduction Pressure ulcers are tissue damages resulting from blood flow restriction, which occurs when the tissue is exposed to high pressure for a long period of time. These painful sores are common in patients and elderly, who spend extended periods of time in bed or wheelchair.

Though these series have similardescriptions, their growth rates often differ substantially, especially over periods as short as a month (table 1). For instance, in the three years ending in December 1982, the difference between monthly growth rates of the two reserves series (absolute value) averaged 8.6 percentage points. Average differences in growth rates were much smaller over periods long...

In two small and isolated wetlands located at the interface of Atlantic Forest Brazilian savanna (Cerrado) in São Paulo State, Brazil, we employed a pixel-based supervised classification approach using combination panchromatic multispectral bands obtained from Landsat 2, 5, 7, CBERS-04A satellites (ranging 80 to 2 m/pixel). addition, acquired DJI Phantom 4 Pro UAV-RGB images twelve different pe...

PURPOSE To study nongoblet and goblet epithelial conjunctival cells after several treatment periods with latanoprost, a prostaglandin analogue. METHODS Twelve patients (20 eyes) were studied before the onset of treatment and after 1, 3, and 6 months of latanoprost use. Impression cytology was carried out to analyze cellular density and morphologic parameters such as minimum and maximum diamet...

Ramadan, the holy month of Muslims, is the ninth month of the Islamic calendar. During fasting, plasma glucose levels and circulating insulin decrease gradually and counter regulatory hormones such as glucagon and catecholamines tend to rise. Diabetic Muslims who insist on fasting should be aware of potential complications and techniques of decreasing the risks. Muslims should be evaluated 2-4 ...
