Diagnostic, treatment, and follow-up of osteoporosis—position statement of the Latin American Federation of Endocrinology
The Latin American Federation of Endocrinology position statement on osteoporosis was developed by endocrinologists from 9 countries. It encompasses the definition, diagnosis, treatment, and follow-up of the d...

Hot infusions and risk of colorectal cancer in Uruguay: a case–control study
The evidence of possible roles for the most common hot infusions intake (tea and coffee) in the risk of colorectal cancer (CRC) needs additional data. Regarding ‘mate’ intake (infusion of Ilex paraguariensis herb...

Influence of geomagnetic activity and atmospheric pressure in hypertensive adults
We performed a study of the systolic and diastolic arterial blood pressure behavior under natural variables such as the atmospheric pressure and the horizontal geomagnetic field component. We worked with a gro...

Artificial reproduction of magnetic fields produced by a natural geomagnetic storm increases systolic blood pressure in rats
The incidence of geomagnetic storms may be associated with changes in circulatory physiology. The way in which the natural variations of the geomagnetic field due to solar activity affects the blood pressure a...

Mid-Term Periodicities in the Solar Magnetic Flux
In this paper we report an analysis of the solar magnetic fluxes estimated in the period 1971–1998. We applied the wavelet technique to find the significant periodicities of these series. We concentrate partic...

Size Distrtibutions of the >10 MeV Solar Proton Events
As has been recognized recently, data on size (frequency) distributions for different sets of solar flare parameters are very helpful in modeling flare and acceleration processes. Relying upon a new arising pa...

Can the low-Activity sun Become Dimmer at Maximum?
After analysing the ratio of sunspot to facular areas along the cycle for solar cycles 12 to 20 we propose two possibilities. One indicates a non-linear behaviour for low-activity cycles and a closer-to-linear...

A straightforward estimation of the maximum sunspot number for cycle 23
Using the annual number of geomagnetically quiet days (aa < 20 γ) for the year after the solar minimum, this precursor method predicts that the maximum sunspot number for cycle 23 will be 140 + 32, indicating tha...

Energy Spectra of Accelerated Solar Protons From Different Sources – I. Reconstruction and Properties of the Source Spectrum
It is widely accepted now that a significant fraction of the solar energetic particles (SEPs) observed at 1 AU after major solar flares are actually accelerated at a CME-driven shock. In addition, in the emerg...

Magnetic flux emergence and geomagnetic activity, a close correlation
We analyse data of magnetic flux emergence for solar cycles 21 and 22, Helios 1 interplanetary shocks for cycle 21, and sudden storm commencements (SSCs) for cycles 11–22. A dominant variation of 3-year period...

Geomagnetic activity and wind velocity during the Maunder minimum
Following a given classification of geomagnetic activity, we obtained aa index values for the Maunder minimum (1645–1715). It is found that the recurrent and fluctuating activities were not appreciable and that t...

The role of flares, CMEs and CME shocks in the generation of solar energetic proton events
We examined solar energetic proton (SEP) events associated with intense Hα flares. We located these flares on the solar disk and obtained their distribution in heliographic longitude as well as their angular dist...

The intense solar activity of march 1989 as a precursor for the occurrence of an ENSO by the end of 1989
We studied the occurrence of ENSO (El Niño-Southern Oscillation) events in relation to solar activity conditions and we found that the events are distributed in two populations, one that could be associated wi...

Solar activity and El Niño: the auroral connection
The occurrence of events El Niño is studied in relation to the periods during which the time series of visible aurorae show local maxima. A significant correlation is found between the distribution of the data...
