Sex Differences in High Sensitivity C-Reactive Protein in Subjects with Risk Factors of Metabolic Syndrome

Abstract Background: Metabolic syndrome (MetS) is associated with a higher risk of all-cause mortality. High-sensitivity C-reactive protein (hsCRP) is a prototypic marker of inflammation usually increased in MetS. Women with MetS-related diseases present higher hsCRP levels than men with MetS-related diseases, suggesting sex differences in inflammatory markers. However, it is unclear whether serum hsCRP levels are already increased in men and/or women with MetS risk factors and without overt diseases or under pharmacological treatment. Objective: To determine the impact of the number of MetS risk factors on serum hsCRP levels in women and men. Methods One hundred and eighteen subjects (70 men and 48 women; 36 ± 1 years) were divided into four groups according to the number of MetS risk factors: healthy group (CT; no risk factors), MetS ≤ 2, MetS = 3, and MetS ≥ 4. Blood was drawn after 12 hours of fasting for measurement of biochemical variables and hsCRP levels, which were determined by immunoturbidimetric assay. Results: The groups with MetS risk factors presented higher serum hsCRP levels when compared with the CT group (p < 0.02). There were no differences in hsCRP levels among groups with MetS risk factors (p > 0.05). The best linear regression model to explain the association between MetS risk factors and hsCRP levels included waist circumference and HDL cholesterol (r = 0.40, p < 0.01). Women with MetS risk factors presented higher hsCRP levels when compared with men (psex < 0.01). Conclusions: Despite the absence of overt diseases and pharmacological treatment, subjects with MetS risk factors already presented increased hsCRP levels, which were significantly higher in women than men at similar conditions.

Fatôres que afetam a determinação da vitamina C na goiaba (Psidium guajava L.)

In the present paper the authors deal with the content of ascorbic acid in guavas (Psidium guajava L.) and the methods of sampling used. Ascorbic acid was determined directly in the photoeletric colorimeter (EEL), after extraction with a 4 per cent solution of oxalic acid. Guavas from various parts of State of S.Paulo were used and the general mean found was around 100 mgm of ascorbic acid per 100 gm fresh weight of the material used for extraction. It was found that there is great variation in the ascorbic acid content according to the condition of the fruit: Ascorbic acid Condition content in Mean mgm/100 gm Green and hard 93,36 - 119,54 102,43 Small green 57,34 - 92,30 83,40 Firm ripe 71,28 - 115,98 90,32 Overripe 63,22 - 85,98 77,36 Of the diferent parts of the fruit, the skin has the highest content; the pulp between the skin and the parts containing the seeds, the "inner pulp" contains little and finallw the central parts, formed by the pulp between seeds, the "inter pulp" a engligible amount. The proportion of ascorbic acid found in the skin, inner pulp and inter pulp may be as high as 1.6: 1: 0. Furthermore, the section near the peduncule and the sepals are richer than equatorial crossections. It was proved that the amount and intensity of sun-light is at least one important factant factor determining differences in the ascorbic acid content of the fruit, which is higer in the parts which have received more light. A sharp decrease was found in the vitamin C content of ripe fruite stored in a home refrigerator. The periods of the preservation were 12-24-48-96 hours and the decrease of the ascorbic acid content m per cent was 23.4 - 42.0 - 66.8 - 76.4 of the initial content of 144.28 mgm/100 gm. The following five different methods of sampling in the determination of the amount of vitamin C were tested, with extraction in a Waring blendor: 1) whole fruit; 2,) sample taken form fruits cut into many small pieces; 3) half of a fruit divided by a crossection at equal distance from both ends; 4) half of fruit divided lenghtwise; 5) a transversal slice of about 1 cm. It was found that the two first methods geve the most reliable results.

Influência de diferentes cavalos e da época de colheita no teor de vitamina C na laranja natal

This paper deals with the variation of the ascorbic acid content in Natal orange as related to the type of rootstock and to the picking time. The determinations were carried out in the juice of fruits which had practically the same ratio total solids/acidity being selected only the highest values of such quotient. The results can be summaryzed as follows: 1. The rootstock has a significant influence on the vitamin C content of the scion; this influence shows two interesting aspects: first, the ascorbic acid contet itself varies as a function of the rootstock; among the three rootstocks studied the highest values were obtained on scion growing on Serra d'água orange; the lowest values were found in "limão rugoso" and "limão francês" was intermediate; the second point to be emphasyzed is the manner of variation of the ascorbic acid content in the different rootstocks: in the case of Serra d'água. the content decreases slowly whereas in "limão francês" the level remains nearly constant and suddenly falls down; finally in the case of "limão rugoso" the amount of ascorbic acid increases significantly to return to the primitive level. 2. The amount of ascorbic acid, not considering the rootstock influence, varies strongly as a function of harvesting time; for this reason the present factor must be borne in mind when sampling for the determination of ascorbic acid in orange is concerned.

Contribuição ao estudo da aplicação do método da diagnose foliar ao algodoeiro (Grossypium hirsutum L., var. I. A. C. 817) II

This paper deal with one experiment carried out in order to study the correlation between petioles analysis and seed cotton yield. A 3X3X3 factorial with respect to N, P2 0(5) and K2 O was installed in a sandy soil with low potash content and medium amounts of total N and easily extractable P. Two kinds of petioles, newly mature were collected for analysis: those attached to fruit hearing branches, and petioles located on the stem; the first group is conventionally named "productive petioles"; The second one is called "not productive petioles". Petioles' sampling was done when the first blossoms appeared. Yield date showed a marked response to potash, both nitrogen and phosphorus having no effect. Very good correlation was found between petioles potash and yield. Both types of petioles samples were equally good indicators of the potash status of the plants. By mathematical treatment of the date it followes that the highed yield which was possible under experimental conditions, 1.562 kg of seed cotton per hectare would be reacher by using 128 kg of K2O per hectare. With this amount of potash supplied to the plants the following K levels would be expected in the petioles: "productive petioles" "not productive petioles" 1,93 % K 1,85 % K

Experimentos com os nematieidas D. D, E.D.B., C.B.P. e Vapam no combate aos nematódeos que parasitam a batatinha em São Paulo

The writers report results on the application of four fumigants (D. D., E. D. B.-40, C. B. P. and Vapam) for control of root-knot and meadow nematodes attacking potato in beds filled with soil artificially inoculated. The data obtained were as follows: a) as reported by previous authors, potato is sensitive to C.B.P., the toxical effects of which disapearing only about 6 and half months after application. On the other hand, C.B.P. proved to have a significative residual nematicidal value, protecting the seeds from root-knot nematodes for a period of two years; b) D. D., E. D. B., and Vapam were effective for controling root-knot but with no residual value, having to be used prior to each planting; c) at the rates used, no nematicide was effective to control meadow nematodes; d) in the conditions of the experiments, all nematicides incited attacks bv Streptomyces scabies. Actually, in some cases scab did not affect any tuber from the check while the entire production from the treated beds was heavily desfigured. The writers assume that as the nematicides killed protozoa and too many bacteria-eating nematodes, they destroyed the biological equilibrium existing in the soil, thus allowing the S. scabies population to reach a high level.
