Physical Function, Quality of Life, and Energy Expenditure During Activities of Daily Living in Obese, Post-Bariatric Surgery, and Healthy Subjects.

Objectives: This study aimed to evaluate physical function (PF), quality of life (QOL), and energy expenditure (EE) during activities of daily living (ADL) in late outcome post-bariatric surgery (BS) patients and to compare them to severe obese individuals and matched controls.

Methods: Sixty-three subjects were included: 21 patients in post-operative (PO) of BS (3-4 years post-Roux-en-Y gastric bypass) with a stable weight for at least 6 months (16 women, 41 ± 11 years old, BMI = 28 ± 4 kg m) (group PO); 21 obese individuals with BS indication (16 women, 44 ± 9 years old, BMI = 44 ± 6 kg m) (group OB); and 21 controls matched to PO by gender, age, and BMI (16 women, 42 ± 12 years old, BMI = 27 ± 6 kg m) (group MC). PF was objectively assessed by the Glittre and modified Glittre ADL-tests.

Validity and Reproducibility of the Glittre ADL-Test in Obese and Post-Bariatric Surgery Patients.

Background: Obese and post-bariatric surgery (BS) subjects often present limitations in physical functioning (PF). The Glittre ADL-test is a simple and useful way to evaluate this outcome. It includes functional activities such as rising from a chair, lifting, carrying weights, and bending over and was never studied in the obese population.

Effect of mesoionic 4-phenyl-5-(cinnamoyl)-1,3,4-thiadiazolium-2-phenylamine chloride derivative salts on the activities of the nitric oxide synthase and arginase of Leishmania amazonensis.

L-arginine is involved in the production of both nitric oxide (NO), mediated by nitric oxide synthase (NOS) and L-ornithine, by arginase activity. It is generally accepted that NO regulation occurs mainly at the transcriptional level of NOS. In a previous work we purported that there is evidence that Leishmania sp.

Leishmania amazonensis trypanothione reductase: evaluation of the effect of glutathione analogs on parasite growth, infectivity and enzyme activity.

Trypanothione reductase (TR) is a major enzyme in trypanosomatids. Its substrate, trypanothione is a molecule containing a tripeptide (L-glutamic acid-cysteine-glycine) coupled to a polyamine, spermidine. This redox system (TR/Trypanothione) is vital for parasite survival within the host cell and has been described as a good target for chemotherapy anti-Leishmania.

Nitric oxide biosynthesis by Leishmania amazonensis promastigotes containing a high percentage of metacyclic forms.

Due to the diversity of its physiological and pathophysiological functions and general ubiquity, the study of nitric oxide (NO) has become of great interest. In this work, it was demonstrated that Leishmania amazonensis promastigotes produces NO, a free radical synthesized from L: -arginine by nitric oxide synthase (NOS). A soluble NOS was purified from L.

Nitric oxide synthase (NOS) characterization in Leishmania amazonensis axenic amastigotes.

Background: Although Leishmania virulence may be modulated by environmental and genetic factors of their mammalian hosts and sand fly vectors, molecular determinants of Leishmania sp. are the key elements. This work evidences that Leishmania amazonensis axenic amastigotes produce comparatively more NO than infective promastigotes.
