Stability of frozen marolo pulp during storage

Marolo, also known as araticum or head-to-black, is a globular berry, a species native to the Brazilian savannah. The aim of this study was to evaluate the physical, chemical, and microbiological stability of frozen marolo pulp during 12 months of frozen storage. It was observed that the levels of ash (0.28-0.22%), protein (0.77-0.71%), lipids (1.75-1.73%), carbohydrates (12.1-10.15%), calorie (67.23-59.01 kcal), sucrose (2.50-1.29%), citric acid (435.63-197.5 µg.g-1), tartaric acid (4.38-1.88 µg.g-1) , acetic acid (470.38-279.25 µg.g-1), ascorbic acid (3.00-0.00 µg.g-1), total pectin (0.67-0.39%), pH (3.88-3.83), and b* chromaticity coordinates (24.85-20.53) decreased reduced during storage, whereas the levels of moisture (85.10-87.19%), color parameters (L* 58.89-62.62 and a* 5.37-7.86), reducing sugars (4.53-5.62%), total soluble sugars (7.1-7.36%), soluble solids (7.0-8.4 ºBrix), total acidity (0.9-1.0%), malic acid (514.13-781.25 µg.g-1), soluble pectin (0.16-0.24%), and antioxidant (6.85-37.35% of DPPH discoloration) increased over the one-year of storage period. According to the physical, chemical, and microbiological parameters assessed, the product can be stored for 12 months without loss of quality with addition of citric acid as a preservative.

Carotenoids are related to the colour and lipid content of the pequi (Caryocar brasiliense Camb.) pulp from the Brazilian Savanna

This study investigated the colour, proximate composition, bioactive compounds (phenolic and carotenoid contents), and antioxidant activity of the pulp of pequi from different regions of the Brazilian Savanna. The colour parameters and the lipid and carotenoid contents of the pulp were significantly different between the samples. The lipid content ranged from 135.4 to 322.5 g/kg. The pequi pulp showed high total phenolic content (1.8 to 3.3 mg GAE/g). The carotenoid amount ranged from 37 to 187 µg/g. The carotenoid content was significantly correlated with the colour and lipid content of the pequi pulp. The antioxidant activity showed a mean IC50 value of 197.9 µg/mL. The pequi pulp is rich in phenolic compounds and carotenoids and has a good antioxidant activity. Its colour is influenced by the carotenoid content, which can be predicted by regression models using routine colour parameters.

Dados demográficos, clínicos e laboratoriais de pacientes com litíase urinária em Fortaleza, Ceará

OBJETIVO: Determinar os dados demográficos, clínicos e laboratoriais de pacientes com litíase urinária em Fortaleza (CE). PACIENTES E MÉTODOS: Trata-se de estudo documental baseado em dados secundários de 197 pacientes litiásicos de Fortaleza, entre 1996-2006. Foram realizadas avaliação clínica e metabólica na urina de 24 horas, para medida de volume urinário e dosagens de creatinina, cálcio, fósforo, ácido úrico, sódio, potássio e magnésio. O pH e a densidade foram determinados na primeira urina da manhã. A cistinúria foi definida por meio da análise de cristais e/ou cálculos. RESULTADOS: A relação homem:mulher foi de 1:1,7. A média de idade na primeira sintomatologia foi de 35,8 ± 13,3 anos, não havendo diferença entre os gêneros. A faixa etária mais acometida foi entre 20 e 39 anos (56,3%); 72,4% apresentaram cólica nefrética, 69,5% procuraram a emergência médica, 46,7% apresentaram um episódio de litíase e 53,3% eram recorrentes. O rim direito foi o mais afetado (44,4%) nas mulheres, enquanto que nos homens o acometimento foi bilateral (39,7%). As principais alterações metabólicas encontradas foram hipernatriúria (80,7%), seguida de hipercalciúria (48,7%), hiperuricosúria (17,3%) e cistinúria em 5 (2,5%). A média do pH urinário foi de 5,74 ± 0,59 e da densidade urinária, de 1015,6 ± 7,1. O volume urinário foi baixo em 43% dos casos. CONCLUSÃO: Em nosso meio, a litíase acomete adultos jovens entre 20-39 anos, com predominância do gênero feminino, e os distúrbios mais frequentes, em ordem decrescente, foram hipernatriúria, hipercalciúria e hiperuricosúria, associadas à baixa ingestão de líquidos.

Modulation of TGF-β signaling by Hypoxia

A tumor is a fast-growing malignant tissue. This creates areas inside the tumor that are distant from local blood vessels to be able to get enough oxygen. This hypoxic condition activates a transcription factor called hypoxia inducible factor (HIF). HIF responses help a cell to adapt to decreased oxygen by activating glycolytic and angiogenesis pathways and by regulating apoptotic responses. Hypoxia drives the upregulation of a growth factor called transforming growth factor beta (TGF-beta). Similar to a hypoxia response, TGF is an important regulator of cell fate. TGF-β and HIF pathways regulate partially overlapping target genes. This regulation can also be cooperative. The TGF-beta signal is initiated by activation of plasma membrane receptors that then activate effector proteins called small mothers against decapentaplegic (Smad) homologs. In healthy tissue, TGF-β keeps cell proliferation and growth under control. During cancer progression, TGF-beta has shown a dual role, whereby it inhibits initial tumor formation but, conversely, in an existent tumor, TGF-beta drives malignant progression. Along with HIF and TGF-beta also protein dephosphorylation is an important regulatory mechanism of cell fate. Protein dephosphorylation is catalyzed by protein phosphatases such as Protein phosphatase 2A (PP2A). PP2A is a ubiquitous phosphatase that can exist in various active forms. PP2A can specifically regulate TGF-beta signaling either by enhancing or inhibiting the receptor activity. This work demonstrates that during hypoxia, PP2A is able to fine-tune TGF-beta signal by specifically targeting Smad3 effector in a Smad7-dependent manner. Inactivation of Smad3 in hypoxia leads to malignant conversion of TGF-beta signaling.
