Lee Index variation and glucose clearance rate in an animal model of obesity with animals supplemented with Ganodema lucidum
The consumption of diets high in sugars and saturated fat are associated with obesity and other comorbidities, as well as glucose intolerance1. Obesity can be influenced by the regular consumption of natural bioactive compounds like those found in Ganoderma lucidum mushroom (GL)2. The main objective of this work is to determine body mass variations (Lee Index) and serum glucose levels in animals fed with diets supplemented with three concentrations of an hydroethanolic extract of GL. The fruiting bodies of GL
were provided by Bioreishi- Agricultura Bioliogica, Lda. Forty-eight male mice (C57BL/6) were acquired and divided into 5 groups: G1-Western Diet 0.2% Cholesterol (WD); G2-Western Control (WC); G3-WD+0.7%g/kg of G. lucidum; G4-WD+1.4%g/kg of G. lucidum; G5- WD+2.8%g/kg of G. lucidum. At 7th and 13th weeks of study, the animals were measured (nasoanal distance in cm) in order to calculate the Lee Index (cubicle root of the weight (g)/the nasoanal length (cm) x 1000). Obesity was defined by a Lee index>310. Glucose intolerance test was performed on 4 animals in each group. The animals were fasted overnight and in the early morning, a 50% glucose solution (2g/kg) was injected intraperitoneally. Blood samples were collected one hour before glucose (time zero) administration and 30, 60 and 120 minutes later.
Serum glucose was determined with the OGCare equipment. Glucose concentration values at time zero were considered control values. All ethical issues were followed (approval nº 8776). The chemical composition of the extract was profiled by HPLC-DAD-ESI/MS. All data were analyzed using the GraphPad Prism® for Windows software (version 7.0). Ganoderic acid H and p-hydroxybenzoic acid were the main triterpenic
and phenolic acids found in the extract, respectively. In respect to the Lee index, the values show that all animals in the experimental groups became obese. In both weeks, G5 showed the highest values (353.45 ± 12.43 and 351.77 ± 12.24 respectively). At week 7, G1 and G2 differed statistically (p<0,05) from G5.
Although G1 and G2 have the lowest Lee values in both weeks, they are the only ones that increase from week 7 to week 13, in contrast to the groups supplemented with GL. Regarding the glucose intolerance test, recorded glucose values at 30 minutes after the injection were increased in all groups, returning to normal values two hours later. At 13th week, the glucose values were increased in all groups in the 30 and 60 minutes
after the intraperitoneal injection. At the end of two hours, the values decreased, but did not return to normal values in all the groups. Although animals in all experimental groups remained obese, animals supplemented with GL decreased their Lee Index. At 7th week the animals showed a normal glucose clearance, but in the last week of the study glucose values did not return to the values initially recorded after two hours, showing
that the animals were not able to maintain the glucose clearance rate.This work was supported by VALORIZEBYPRODUCTS Project, reference n.º029152; CIMO (UIDB/00690/2020); Project MicoCoating (PDR2020-101-031472); and L.

Ganoderma lucidum in an animal model of obesity: preliminary results
Obesity is an emerging health problem worldwide.
Hypercaloric or hyperlipidemic diets have been used
as models of obesity induction in laboratory animals. Obesity
can be influenced by regular consumption of natural bioactive
compounds. Mushrooms, such as Ganoderma lucidum
(GL), have been used in the human diet since ancient times
and include a wide variety of biomolecules with medicinal
properties. The main objective of this work was to study the
effects of G. lucidum in an animal model of obesity.info:eu-repo/semantics/publishedVersio
Polypharmacy Among The Elderly In The City Of São Paulo, Brazil - Sabe Study [polifarmácia Entre Idosos Do Município De São Paulo - Estudo Sabe]
Polypharmacy for the elderly and associated factors were assessed. A cross-sectional study was conducted using data from the SABE Study (Health, Well-being and Aging), 2006. 1,115 individuals representing 422,377 elderly aged 65 or more, living in São Paulo City, were interviewed. Polypharmacy was defined as the use of five or more medications. A multivariate regression logistics was used. Polypharmacy prevalence was 36%. Female (OR = 1.7; IC 95%: 1.0; 2.9), age over 75 years (OR = 1.9; CI 95%: 1.3; 2.7), higher income (OR = 1.8; CI 95%: 1.2; 2.8), working (OR = 1.8; CI 95%: 1.1; 2.9), regular self assessed health (OR = 1.6; CI 95%: 1.1; 2.3) or poor (OR = 2.6; CI 95%: 1.4; 4.9), hypertension (OR = 2.0; CI 95%: 1.4; 2.9), diabetes (OR = 4.1; CI 95%: 2.2; 7.5), rheumatic diseases (OR = 2.3; CI 95%: 1.5; 3.6) and cardiac problems (OR = 2.9; CI 95%: 1.9; 4.5) were associated positively with polypharmacy. Using only the public health system (OR = 0.5, 95% CI: 0.3; 0.7) was inversely associated with polypharmacy. Medicines for the cardiovascular system and for the alimentary tract and metabolism were the most used. The knowledge of factors associated with polypharmacy, such as those identified in this study, may be useful to alert health professionals about the importance of identifying and monitoring the elderly groups most vulnerable to polypharmacy.154817827Ramos, L.R., Fatores determinantes do envelhecimento saudável em idosos residentes em centro urbano: Projeto Epidoso, São Paulo (2003) Cad Saúde Pública, 19, pp. 793-798(2002) Active Ageing.

A proposed methodology for the correction of the Leaf Area Index measured with a ceptometer for pinus and eucalyptus forests = Proposta de uma methodologia para a correcao do indice de area foliar medido pelo ceptometro em provoamentos de pinus e eucalyptus
Leaf area index (LAI) is an important parameter controlling many biological and physiological processes associated with vegetation on the Earth's surface, such as photosynthesis, respiration, transpiration,
carbon and nutrient cycle and rainfall interception. LAI can be measured indirectly by sunfleck ceptometers in an easy and non-destructive way but this practical methodology tends to underestimated when measured
by these instruments. Trying to correct this underestimation, some previous studies heave proposed the multiplication of the observed LAI value by a constant correction factor. The assumption of this work is LAI obtained from the allometric equations are not so problematic and can be used as a reference LAI to develop a new methodology to correct the ceptometer one. This new methodology indicates that the bias (the difference between the ceptometer and the reference LAI) is estimated as a function of the basal area per unit ground area and that bias is summed to the measured value. This study has proved that while the measured Pinus LAI needs a correction, there is no need for that correction for the Eucalyptus LAI. However, even for this last specie the proposed methodology gives closer estimations to the real LAI values
