Baroreflex sensitivity in frailty syndrome BJMBR
Buto,M.S.S.; Catai,A.M.; Vassimon-Barroso,V.; Gois,M.O.; Porta,A.; Takahashi,A.C.M..
Frailty is related to a decrease in the physiological reserves, which causes difficulties in maintaining homeostasis. An example of physiological mechanisms for cardiovascular homeostasis is the baroreflex. The aim of this study was to compare baroreflex among frail, prefrail, and nonfrail individuals, in supine and orthostatic positions. Community-dwelling older adults were evaluated and categorized into frail, prefrail, or nonfrail groups, according to frailty phenotype. The RR interval (RRi) and systolic blood pressure (SBP) series were recorded for 15 min in the supine and 15 min in the orthostatic positions. Mean and variance of RRi and SBP, and baroreflex evaluated by phase, gain (α), and coherence (K2) were determined. A two-way repeated measures...

Sorbímetro (Um aparêlho para a determinação das relações solo/água) Anais da ESALQ
Ranzani,G.; Porta,A..
Os autores descrevem um aparelho destinado à medida contínua da água absorvida pela TFSA em condições de laboratório. O sorbímetro, cujo funcionamento obedece ao princípio dos vasos comunicantes, consta de um tubo em U cujos ramos verticais se ligam respectivamente à uma coluna de terra e à uma bureta de 100 ml. A bureta restabelece no tubo, a água absorvida pela terra. As leituras de bureta substituem as pesagens do método gravimétrico. O aparelho é recomendado para medidas a intervalos de tempo para os quais, o método usual é ineficiente.

Spectral and symbolic analysis of the effect of gender and postural change on cardiac autonomic modulation in healthy elderly subjects BJMBR
Perseguini,N.M.; Takahashi,A.C.M.; Rebelatto,J.R.; Silva,E.; Borghi-Silva,A.; Porta,A.; Montano,N.; Catai,A.M..
The objective of this study was to use linear and non-linear methods to investigate cardiac autonomic modulation in healthy elderly men and women in response to a postural change from the supine to the standing position. Fourteen men (66.1 ± 3.5 years) and 10 women (65.3 ± 3.3 years) were evaluated. Beat-to-beat heart rate was recorded in the supine and standing positions. Heart rate variability was studied by spectral analysis, including both low (LFnu-cardiac sympathetic modulation (CSM) indicator) and high (HFnu-cardiac vagal modulation (CVM) indicator) frequencies in normalized units as well as the low frequency/high frequency (LF/HF) ratio. Symbolic analysis was performed using the following indexes: 0V% (CSM indicator), 1V% (CSM and CVM indicators),...

Successful domino liver transplantation in maple syrup urine disease using a related living donor BJMBR
Feier,F.H.; Miura,I.K.; Fonseca,E.A.; Porta,G.; Pugliese,R.; Porta,A.; Schwartz,I.V.D.; Margutti,A.V.B.; Camelo Jr,J.S.; Yamaguchi,S.N.; Taveira,A.T.; Candido,H.; Benavides,M.; Danesi,V.; Guimaraes,T.; Kondo,M.; Chapchap,P.; Neto,J. Seda.
Maple syrup urine disease (MSUD) is an autosomal recessive disease associated with high levels of branched-chain amino acids. Children with MSUD can present severe neurological damage, but liver transplantation (LT) allows the patient to resume a normal diet and avoid further neurological damage. The use of living related donors has been controversial because parents are obligatory heterozygotes. We report a case of a 2-year-old child with MSUD who underwent a living donor LT. The donor was the patient's mother, and his liver was then used as a domino graft. The postoperative course was uneventful in all three subjects. DNA analysis performed after the transplantation (sequencing of the coding regions of BCKDHA, BCKDHB, andDBT genes) showed that the MSUD...
