New indicators proposed to assess tuberculosis control and elimination in Cuba
R. González,Edilberto; Armas,Luisa;
MEDICC Review , 2012, DOI: 10.1590/S1555-79602012000400009
Abstract: following 48 years of successful operation of the national tuberculosis control program, cuban health authorities have placed tuberculosis elimination on the agenda. to this end some tuberculosis control processes and their indicators need redesigned and new ones introduced, related to: number and proportion of suspected tuberculosis cases among vulnerable population groups; tuberculosis suspects with sputum microscopy and culture results useful for diagnosis (interpretable); and number of identified contacts of reported tuberculosis cases who were fully investigated. such new indicators have been validated and successfully implemented in all provinces (2011-12) and are in the approval pipeline for generalized use in the national tuberculosis control program. these indicators complement existing criteria for quality of case detection and support more comprehensive program performance assessment.
Metabolic Post-feeding Changes in Fat Body and Hemolymph of Dipetalogaster maximus (Hemiptera:Reduviidae)
Canavoso, Lilián E;Rubiolo, Edilberto R;
Memórias do Instituto Oswaldo Cruz , 1998, DOI: 10.1590/S0074-02761998000200018
Abstract: lipids and glycogen in fat body as well as the modifications in the wet weight of this organ were evaluated in an unfed insect, dipetalogaster maximus, on day 5 after adult ecdysis (time 0) and during a 30-day period after ingestion of blood meal. total lipids, high density lipophorin (hdlp), carbohydrates, total proteins and uric acid were determined in the hemolymph during the same period. fat body wet weight was maximum on day 10 post-feeding and represented on day 30 only 42% of the maximum weight. lipids stored in the fat body increased up to day 15 reaching 24% of the total weight of tissue. glycogen was maximum on day 20, representing approximately 3% of the fat body weight. hdlp represented at all times between 17-24% of the total proteins, whose levels ranged between 35 and 47 mg/ml. uric acid showed at 20, 25 and 30 days similar levels and significantly higher than the ones shown at days 10 and 15. hemolymphatic lipids fluctuated during starvation between 3-4.4 mg/ml and carbohydrates showed a maximum on day 15 after a blood meal, decreasing up to 0.26 mg/ml on day 25. the above results suggest that during physiological events such as starvation, the availability of nutrients is affected, involving principally the fat body reserves

Metabolic Post-feeding Changes in Fat Body and Hemolymph of Dipetalogaster maximus (Hemiptera:Reduviidae)

Memórias do Instituto Oswaldo Cruz , 1998,
Abstract: Lipids and glycogen in fat body as well as the modifications in the wet weight of this organ were evaluated in an unfed insect, Dipetalogaster maximus, on day 5 after adult ecdysis (time 0) and during a 30-day period after ingestion of blood meal. Total lipids, high density lipophorin (HDLp), carbohydrates, total proteins and uric acid were determined in the hemolymph during the same period. Fat body wet weight was maximum on day 10 post-feeding and represented on day 30 only 42% of the maximum weight. Lipids stored in the fat body increased up to day 15 reaching 24% of the total weight of tissue. Glycogen was maximum on day 20, representing approximately 3% of the fat body weight. HDLp represented at all times between 17-24% of the total proteins, whose levels ranged between 35 and 47 mg/ml. Uric acid showed at 20, 25 and 30 days similar levels and significantly higher than the ones shown at days 10 and 15. Hemolymphatic lipids fluctuated during starvation between 3-4.4 mg/ml and carbohydrates showed a maximum on day 15 after a blood meal, decreasing up to 0.26 mg/ml on day 25. The above results suggest that during physiological events such as starvation, the availability of nutrients is affected, involving principally the fat body reserves
Amburosides C-H and 6-O-protocatechuoyl coumarin from Amburana cearensis
Canuto, Kirley M;Lima, Mary Anne S;Silveira, Edilberto R;
Journal of the Brazilian Chemical Society , 2010, DOI: 10.1590/S0103-50532010000900022
Abstract: six new amburosides (1-6) and a novel 6-coumaryl protocatechuate (7) were isolated from the seeds and trunk bark of amburana cearensis, together with coumarin, 6-hydroxycoumarin, isokaempferide, formononetin, vanillic acid, amburoside a and (e)-o-coumaric acid. the chemical structures of the new compounds were elucidated by means of nmr (cosy, hsqc, hmbc and noesy) and hrms spectral analyses.
Flight metabolism in Panstrongylus megistus (Hemiptera: Reduviidae): the role of carbohydrates and lipids
Canavoso, Lilián E;Stariolo, Raúl;Rubiolo, Edilberto R;
Memórias do Instituto Oswaldo Cruz , 2003, DOI: 10.1590/S0074-02762003000700009
Abstract: the metabolism of lipids and carbohydrates related to flight activity in panstrongylus megistus was investigated. insects were subjected to different times of flight under laboratory conditions and changes in total lipids, lipophorin density and carbohydrates were followed in the hemolymph. lipids and glycogen were also assayed in fat body and flight muscle. in resting insects, hemolymph lipids averaged 3.4 mg/ml and significantly increased after 45 min of flight (8.8 mg/ml, p < 0.001). high-density lipophorin was the sole lipoprotein observed in resting animals. a second fraction with lower density corresponding to low-density lipophorin appeared in insects subjected to flight. particles from both fractions showed significant differences in diacylglycerol content and size. in resting insects, carbohydrate levels averaged 0.52 mg/ml. they sharply declined more than twofold after 15 min of flight, being undetectable in hemolymph of insects flown for 45 min. lipid and glycogen from fat body and flight muscle decreased significantly after 45 min of flight. taken together, the results indicate that p. megistus uses carbohydrates during the initiation of the flight after which, switching fuel for flight from carbohydrates to lipids.

Química Nova , 2007, DOI: 10.1590/S0100-40422007000800025
Abstract: phytochemical analysis of the kino of eucalyptus citriodora led to the isolation of 1-o,2-o-digaloil-6-o-trans -p-cumaroil-b-d-glucopyranoside, 1-o-trans-p-cumaroil-6-o -cinamoil-b-d-glucopyranoside, a and b 6-o-trans-p-cumaroil-d-glucopyranoside, 7-methylaromadendrin-4'-o-6''- trans-p-cumaroil-b-d-glucopyranoside, aromadendrin, aromadendrin-7-methyl-ether, naringenin, sakuranetin, kaempferol-7-methyl-ether and galic acid. structural elucidation of the isolated compounds was established on the basis of spectral data, particularly by the use of 1d nmr and several 2d shift correlated nmr pulse sequences (1h,1h-cosy, hmqc, hmbc).

Insects were subjected to different times of flight under laboratory conditions and changes in total lipids, lipophorin density and carbohydrates were followed in the hemolymph. Lipids and glycogen were also assayed in fat body and flight muscle. In resting insects, hemolymph lipids averaged 3.4 mg/ml and significantly increased after 45 min of flight (8.8 mg/ml, P < 0.001). High-density lipophorin was the sole lipoprotein observed in resting animals. A second fraction with lower density corresponding to low-density lipophorin appeared in insects subjected to flight. Particles from both fractions showed significant differences in diacylglycerol content and size. In resting insects, carbohydrate levels averaged 0.52 mg/ml. They sharply declined more than twofold after 15 min of flight, being undetectable in hemolymph of insects flown for 45 min. Lipid and glycogen from fat body and flight muscle decreased significantly after 45 min of flight. Taken together, the results indicate that P. megistus uses carbohydrates during the initiation of the flight after which, switching fuel for flight from carbohydrates to lipids.
Symplectic Dirac Equation
R. G. G. Amorim,S. C. Ulhoa,Edilberto O. Silva
Physics , 2015, DOI: 10.1007/s13538-015-0368-1
Abstract: Symplectic unitary representations for the Poincar\'{e} group are studied. The formalism is based on the noncommutative structure of the star-product, and using group theory approach as a guide, a consistent physical theory in phase space is constructed. The state of a quantum mechanics system is described by a quasi-probability amplitude that is in association with the Wigner function. As a result, the Klein-Gordon and Dirac equations are derived in phase space. As an application, we study the Dirac equation with electromagnetic interaction in phase space.
