RESUMEN

Scope: fructose consumption from added sugars correlates with the epidemic rise in MetS and CVD. Maternal fructose intake has been described to program metabolic diseases in progeny. However, consumption of fructose-containing beverages is allowed during gestation. Cholesterol is also a well-known risk factor for CVD. Therefore, it is essential to study Western diets which combine fructose and cholesterol and how maternal fructose can influence the response of progeny to these diets. Methods and results: a high-cholesterol (2%) diet combined with liquid fructose (10%), as a model of an unhealthy Western diet, was administered to descendants from control and fructose-fed mothers. Gene (mRNA and protein) expression and plasma, fecal and tissue parameters of cholesterol metabolism were measured. Interestingly, progeny from fructose-fed dams consumed less liquid fructose and cholesterol-rich chow than males from control mothers. Moreover, descendants of fructose-fed mothers fed a Western diet showed an increased cholesterol elimination through bile and feces than males from control mothers. Despite these mitigating circumstances to develop a proatherogenic profile, the same degree of hypercholesterolemia and severity of steatosis were observed in all descendants fed a Western diet, independently of maternal intake. An increased intestinal absorption of cholesterol, synthesis, esterification, and assembly into lipoprotein found in males from fructose-fed dams consuming a Western diet could be the cause. Moreover, an augmented GLP2 signalling seen in these animals would explain this enhanced lipid absorption. Conclusions: maternal fructose intake, through a fetal programming, makes a Western diet considerably more harmful in their descendants than in the offspring from control mothers.

RESUMEN Diversas terapias son empleadas para el manejo del enfisema subcutáneo en adultos, pero no se ha encontrado alguna referencia del drenaje subcutáneo mediante la técnica de Beck en pacientes pediátricos. Presentamos el caso clínico de una paciente de catorce años de edad con un trauma cerrado debido a una caída desde una altura de diez metros. Al ingreso, la paciente muestra pérdida de conciencia y desarrolla un síndrome de distrés respiratorio, por lo que se le indica ventilación mecánica. Siete días después se produce un enfisema subcutáneo y se realiza una inserción con angiocatéter fenestrado empleando la técnica de Beck. El enfisema en la zona superior del tórax y el rostro disminuyó a las 24 horas, y a las 72 horas la resolución fue completa.

ABSTRACT Several therapies are used for the management of subcutaneous emphysema in adults, but no reference to subcutaneous drainage using Beck's technique has been found in pediatric patients. This is the clinical case of a 14-year-old female patient who presented a blunt force trauma that resulted from a ten-meter-high fall. On admission, she was unconscious and developed respiratory distress syndrome, thus mechanical ventilation was indicated. Seven days later, subcutaneous emphysema occurred, and a fenestrated angiocatheter was inserted using Beck's method. At 24 hours, the emphysema was reduced in the upper chest and face, and, at 72 hours, complete resolution was observed.

RESUMEN

La pleitrofina (PTN) en un péptido implicado en el desarrollo y el mantenimiento del tejido óseo, y con importantes funciones en los procesos inflamatorios. Sin embargo, la deleción de la PTN en modelos murinos no produce un deterioro óseo significativo, sin que hasta la fecha se hayan estudiado los mecanismos que compensan su perdida. Con este estudio quisimos comprobar cómo afecta la deleción de PTN y la inflamación aguda a la expresión de factores óseos. Para ello empleamos ratones hembra de tres meses deficientes para la PTN (PTNKo) a las que indujimos una inflamación aguda por administración de lipopolisacárido (LPS). Se aislaron las vértebras y las tibias para poder medir la expresión de genes y realizar un recuento de osteocitos. En cultivos celulares comprobamos si la PTN podía proteger a células MC3T3 (osteoblásticas) y MLOY4 (osteocitos) de la inducción de muerte celular producida por etopósido. Nuestros resultados muestran que la expresión de osteocalcina está incrementada en las vértebras de los ratones PTNKo, y que la inflamación produjo el incremento de expresión de podaplanina (E11), conexina 43 (Cox43) y el péptido relacionado con la parathormona (PTHrP) en los ratones PTNKo tratados con LPS. La administración de PTN redujo de manera significativa la muerte inducida por etopósido en cultivos de células MC3T3 y MLOY4. En conclusión, la deficiencia de PTN indujo un aumento de la expresión de OCN, y la inflamación aguda produjo la sobrexpresión de E11, PTHrP, y Cox43 en ratones PTNKo. La PTN aumentó la viabilidad de células osteblásticas y osteocitos frente al tratamiento con etopósido

Pleiotrophin (PTN) is a peptide involved in the development and maintenance of bone tissue with important functions in inflammatory processes. However, the deletion of PTN in murine models does not produce a significant bone deterioration, but the mechanisms that compensate for its loss have not been studied to date. Our study was aimed at verifying how the deletion of PTN and acute inflammation affect the expression of bone factors. To this end, we used three-month-old female mice deficient for PTN (PTNKo) to which we induced acute inflammation by administration of lipopolysaccharide (LPS). Vertebrae and tibiae were isolated to measure gene expression and carry out an osteocyte count. In cell cultures, we checked whether PTN could protect MC3T3 (osteoblast) and MLOY4 (osteocyte) cells from the induction of cell death caused by etoposide. Our results show that the expression of osteocalcin is increased in the vertebrae of PTNKo mice, and that inflammation increased the expression of podhalanin (E11), connexin 43 (Cox43) and the parathormone-related peptide (PTHrP) in the PTNKo mice treated with LPS. Administering PTN significantly reduced etoposide-induced death in MC3T3 and MLOY4 cell cultures. Thus, PTN deficiency induced increased expression of OCN, and acute inflammation produced overexpression of E11, PTHrP, and Cox43 in PTNKo mice. PTN increased the viability of osteoblastic cells and osteocytes compared to etoposide treatment

RESUMEN

We provide transferable force fields for oxygen, nitrogen, and carbon monoxide that are able to reproduce experimental adsorption in both pure silica and alumino-substituted zeolites at cryogenic and high temperatures. The force field parameters can be combined with those previously reported for carbon dioxide, methane, and argon, opening the possibility for studying mixtures of interest containing the six components. Using these force field parameters we obtained some adsorption isotherms at cryogenic temperatures that at first sight were in discrepancies with experimental values for certain molecules and structures. We attribute these discrepancies to the sensitiveness of the equipment and to kinetic impedimenta that can lead to erratic results. Additional problems can be found during simulations when extra-framework cations are present in the system as their lack of mobility at low temperatures could lead to kinetic effects that hinder experimental adsorption.

RESUMEN

Molecular simulations have been used to investigate at the molecular level the suitability of zeolites with different topology on the adsorption, diffusion and separation of a nitrogen-sulfur hexafluoride mixture containing the latter at low concentration. This mixture represents the best alternative for the sulfur hexafluoride in industry since it reduces the use of this powerful greenhouse gas. A variety of zeolites are tested with the aim to identify the best structure for the recycling of sulfur hexafluoride in order to avoid its emission to the atmosphere and to overcome the experimental difficulties of its handling. Even though all zeolites show preferential adsorption of sulfur hexafluoride, we identified local structural features that reduce the affinity for sulfur hexafluoride in zeolites such as MOR and EON, providing exclusive adsorption sites for nitrogen. Structures such as ASV and FER were initially considered as good candidates based on their adsorption features. However, they were further discarded based on their diffusion properties. Regarding operation conditions for separation, the range of pressure that spans from 3 × 10(2) to 3 × 10(3) kPa was identified as the optimal to obtain the highest adsorption loading and the largest SF6/N2 selectivity. Based on these findings, zeolites BEC, ITR, IWW, and SFG were selected as the most promising materials for this particular separation.

RESUMEN

We used a combination of experiments and molecular simulations to investigate at the molecular level the effects of zeolite structure on the adsorption and diffusion of sulfur dioxide, carbon dioxide and carbon monoxide as well as separation processes of their mixtures. Our study involved different zeolite topologies and revealed numerous structure-property trends depending on the temperature and pressure conditions. Sulfur dioxide, which has the strongest interactions with zeolites due to its size and polarity, showed the largest adsorption across investigated temperatures and pressures. Our results indicate that structures with channel-type pore topology and low pore volume are the most promising for selective adsorption of sulfur dioxide over carbon dioxide and carbon monoxide under room conditions, while structures with higher pore volume exhibit better storage capacity at higher pressure. Our results emphasize the need for considering both adsorption and diffusion processes in the selection of the optimal structure for a given separation process. Our findings help to identify the best materials for effective separation processes under realistic operating conditions.

RESUMEN

ZIF-8 is a zeolitic imidazolate framework with very good thermal and chemical stability that opens up many applications that are not feasible by other metal-organic frameowrks (MOFs) and zeolites. Several works report the adsorption properties of ZIF-8 for strategic gases. However, despite the vast experimental corpus of data reported, there seems yet to be a dearth in the understanding of the gas adsorption properties. In this work we provide insights at a molecular level on the mechanisms governing the ZIF-8 structural deformation during molecular adsorption. We demonstrate that the ZIF-8 structural deformation during the adsorption of different molecules at cryogenic temperature goes beyond the gas-induced rotation of the imidazolate linkers. We combine experimental and simulation studies to demonstrate that this deformation is governed by the polarizability and molecular size and shape of the gases, and that the stepped adsorption behavior is defined by the packing arrangement of the guest inside the host.

RESUMEN

Insulin resistance is a characteristic of late pregnancy, and adipose tissue is one of the tissues that most actively contributes to the reduced maternal insulin sensitivity. There is evidence that pregnancy is a condition of moderate inflammation, although the physiological role of this low-grade inflammation remains unclear. The present study was designed to validate whether low-grade inflammation plays a role in the development of insulin resistance in adipose tissue during late pregnancy. To this end, we analyzed proinflammatory adipokines and kinases in lumbar adipose tissue of nonpregnant and late pregnant rats at d 18 and 20 of gestation. We found that circulating and tissue levels of adipokines, such as IL-1ß, plasminogen activator inhibitor-1, and TNF-α, were increased at late pregnancy, which correlated with insulin resistance. The observed increase in adipokines coincided with an enhanced activation of p38 MAPK in adipose tissue. Treatment of pregnant rats with the p38 MAPK inhibitor SB 202190 increased insulin-stimulated tyrosine phosphorylation of the insulin receptor (IR) and IR substrate-1 in adipose tissue, which was paralleled by a reduction of IR substrate-1 serine phosphorylation and an enhancement of the metabolic actions of insulin. These results indicate that activation of p38 MAPK in adipose tissue contributes to adipose tissue insulin resistance at late pregnancy. Furthermore, the results of the present study support the hypothesis that physiological low-grade inflammation in the maternal organism is relevant to the development of pregnancy-associated insulin resistance.

RESUMEN

Insulin resistance plays a role in the pathogenesis of diabetes, including gestational diabetes. The glucose clamp is considered the gold standard for determining in vivo insulin sensitivity, both in human and in animal models. However, the clamp is laborious, time consuming and, in animals, requires anesthesia and collection of multiple blood samples. In human studies, a number of simple indexes, derived from fasting glucose and insulin levels, have been obtained and validated against the glucose clamp. However, these indexes have not been validated in rats and their accuracy in predicting altered insulin sensitivity remains to be established. In the present study, we have evaluated whether indirect estimates based on fasting glucose and insulin levels are valid predictors of insulin sensitivity in nonpregnant and 20-day-pregnant Wistar and Sprague-Dawley rats. We have analyzed the homeostasis model assessment of insulin resistance (HOMA-IR), the quantitative insulin sensitivity check index (QUICKI), and the fasting glucose-to-insulin ratio (FGIR) by comparing them with the insulin sensitivity (SI(Clamp)) values obtained during the hyperinsulinemic-isoglycemic clamp. We have performed a calibration analysis to evaluate the ability of these indexes to accurately predict insulin sensitivity as determined by the reference glucose clamp. Finally, to assess the reliability of these indexes for the identification of animals with impaired insulin sensitivity, performance of the indexes was analyzed by receiver operating characteristic (ROC) curves in Wistar and Sprague-Dawley rats. We found that HOMA-IR, QUICKI, and FGIR correlated significantly with SI(Clamp), exhibited good sensitivity and specificity, accurately predicted SI(Clamp), and yielded lower insulin sensitivity in pregnant than in nonpregnant rats. Together, our data demonstrate that these indexes provide an easy and accurate measure of insulin sensitivity during pregnancy in the rat.

RESUMEN

OBJECTIVE: At present, growth regulating factors in the transition from fetal to postnatal life remain unknown. The purpose of this study was to analyze the influence of GH and nutrition on neonatal growth. PATIENTS AND METHODS: Serum and 24-hour urine GH levels, various anthopometric variables and daily energy and nutrient intake were measured in appropriate (AGA), large (LGA) and small for gestational age (SGA) newborn infants. These variables were measured at 1 (n = 98), 3 (n = 41) and 5 weeks of postnatal age (n = 8). RESULTS: The highest GH levels at the 1st week of postnatal life were obtained in preterm SGA infants (GHs: 61.4 +/- 20.0 microUI/m; GHu: 18.6 +/- 10.3 ng/kg/24 h). GH levels decreased in preterm infants, so that differences between groups failed to be significant at the third and fifth weeks of postnatal life. Urinary GH excretion did not show significant variations in the control group during the study (1st wk 3.0 +/- 3.5; 3rd wk 2.3 +/- 2.7; 5th wk 3.2 +/- 4.7 ng/kg/24 h). Daily protein intake had a direct relationship with both triceps skinfold and weight and head perimeter increase. SGA preterm infants showed a higher fat increase compared to AGA preterm infants. Serum and urinary GH levels were not related to the anthopometric variables studied. CONCLUSIONS: There are differences in GH secretion and body composition between SGA and AGA preterm infants. GH probably does not contribute to neonatal growth.

RESUMEN

One of the important tasks for a nurse is to insure that the newborn receives all the nourishment that it needs. A well fed baby is healthier, experiences a shorter hospital stay and develops a stronger bond with its mother. To prove this point a study was performed on a group of low birth weight newborns (free of other pathological symptoms) to compare nutrition against hospitalization time. 85 children of both sexes were divided into 3 groups: premature but of normal gestational size, premature but small for gestational size, and full term but small for gestational size; all had a birth weight superior to 2 kilos and were examined postpartum on their first and third week. The groups were then subdivided into 2 groups: one received only artificial milk formula and the other group received their mothers' milk through a bottle. The children that drank the maternal milk required fewer days in the hospital (18 +/- 6 days versus 27 +/- 7 days for those drinking only formula) and had a smaller percentage of weight loss after birth (3.7 +/- 2.0% versus 5.2 +/- 2.9%), demonstrating a significant difference in their overall health.
