There are around 15 million preterm newborns(PT) eve ry year(Atienza-Navarro et al., 2020).With these figures in mind,prematurity represents a major health problem worldwide and it is a leading cause of infant mortality,accounting for up to 35%of all deaths among newborns(Atienza-Navarro et al.,2020) and up to 18% of the deaths among children under 5 years of age.

Chemical absorption is a crucial step for several chemical processes such as ammonia production, coal gasification, methane reforming,ethylene oxide manufacturing and treatment of associated gas streams [1]. It is considered one of the main processes to eliminate CO_2 emissions from power plants by *** of new solvents are of high interest in chemical absorption for carbon capture. For the design of the absorption and desorption columns it is essential to know the vapour-liquid equilibrium(VLE), heat of absorption and densities. N,N-diethylethanolamine(DEEA) appeared as one of the amines with the lowest amount of energy needed for its regeneration [2], which would directly decrease the operation costs. DEEA has a high CO_2 loading of 1 mol/mol of amine compared to the traditional MEA solvent(0.5 mol/mol amine) and is obtained from renewable sources[1]. The main weakness is its low absorption rate and consequently the use of promoters is *** this work, a thermodynamic model based on the electrolyte non-random two-liquid theory(eNRTL) was created and fitted to correlate and predict the partial and total pressures of the unloaded and loaded aqueous DEEA solutions. New interaction parameters were obtained for the binary and tertiary system. This model represents the vapour pressures of the pure components, DEEA and H_2 O, with AARD of 1.9% and 1.73%respectively. Furthermore, the fitted model predicts the total pressure above the binary system, H_2O-DEEA, with AARD of 0.05%. The excess of enthalpy and densities are predicted with AARD of 5.63% and 1.38% respectively. The tertiary system, H_2O-DEEA-CO_2, is fitted for 2 M and5 M DEEA solutions with loading between 0.042 and 0.9 mol CO_2/mol amine up to 80 ℃. Results of CO_2 partial pressures and total pressures are reproduced, with AARD of 19.45% and 16.18% respectively. Densities are predicted with an AARD of 1.52%.

Type 2 diabetes （T2D） is an important risk factor for developing dementias, including Alzheimer＇s disease （AD）. Hyperinsulin- emia and glucose intolerance, as features of T2D, might increase the neurodegeneration process, synaptic loss and brain atrophy, leading to cognitive impairment observed in AD. Also, adult neurogenesis seems to be impaired in AD models. Therefore, we have studied morphological alterations, cell proliferation and neurogenesis in the central nervous system （CNS） from a classical model of T2D, the db/db mouse, and in a prediabetes insulin-resistant model, obtained after long-term high fat diet （HFD） administration to C57B1/6 mice. Db/db mice showed an age-dependent cortical and hippocampal atrophy, whereas in HFD mice cortex and hippocampus were preserved. Neurogen- esis and cell proliferation were increased in young db/db mice, when compared with control mice, whereas no differences were detected in the prediabetic model. We also detected significant correlations between metabolic parameters and central atrophy, altered proliferation and neurogenesis in the central nervous system. Altogether these data support that glycaemia control in elderly patients, could help to control central alterations and improve dementia prognosis.

AIM:To evaluate rational and experiential intelligence in irritable bowel syndrome (IBS) ***:We recruited 100 subjects with IBS as per Rome criteria(50 consulters and 50 non-consulters) and 100 healthy controls,matched by age,sex and educational *** and controls completed a clinical questionnaire(including symptom characteristics and medical consultation)and the following tests:rational-intelligence(Wechsler Adult Intelligence Scale,3rd edition);experiential intelligence(Constructive Thinking Inventory);personality(NEO personality inventory); psychopathology(MMPI-2),anxiety(state-trait anxiety inventory)and life events(social readjustment rating scale).Analysis of variance was used to compare the test results of IBS-sufferers and controls,and a logistic regression model was then constructed and adjusted for age,sex and educational level to evaluate any possible association with ***: No differences were found between IBS cases and controls in terms of IQ (102.0 ±10.8 vs 102.8±12.6), but IBS sufferers scored significantly lower in global constructive thinking (43.7±9.4 vs 49.6±9.7). In the logistic regression model, global constructive thinking score was independently linked to suffering from IBS [OR 0.92 (0.87-0.97)], without significant OR for total ***: IBS subjects do not show lower rational intelligence than controls, but lower experiential intelligence is nevertheless associated with IBS.

Intraductal papillary neoplasm of the bile duct(IPNB) is a rare bile duct neoplasm mostly found in far eastern nations where hepatolithiasis and clonorchiasis infections are endemic. In western countries,it is very rare and the etiology is unknown. In this article,we report the first IPNB patient we encountered in our clinic and a literature review. The patient is a 38-yearold female with a history of choledocholithiasis who presented with obstructive jaundice. She was found to have a papillary mass at the junction of the right hepatic duct and common hepatic duct with six masses in the liver parenchyma. The immunophenotypic and histologic features of the tumor are consistent with IPNB,gastric subtype. The patient had a partial hepatectomy and has been receiving palliative chemotherapy. In a search of Pub Med database,we collected 354 IPNB patients reported in 22 articles. In these patients,52.8% were from Japan and 27.7% were from western countries including the United States(11.0%). The age of the patients ranged from 35 to 80 years old with an average of 64.6. Male/female ratio was 1.5. Macroscopically,57.5% of the tumors were in the left lobe and 29.5% were in the right lobe. The average size of the tumor were 4.2 cm at the time of diagnosis. Histologically,pancreato-biliary subtype accounted for 41.8%,intestinal 28.0%,gastric 13.5% and oncocytic 16%. An invasive component is most often present in the pancreato-biliary and gastric subtypes. Despite recent advanced technologies,diagnosis of IPNB is still challenging,especially in western countries due to its rarity. Defined clinicopathologic features are in demand for the accurate diagnosis and proper treatment.

Carbon nanodots (CNDs) with enriched periphery carboxylic groups were synthesized using the low-cost starting material glucose. The obtained CNDs were assembled onto Au electrodes following one of two strategies: covalent bonding, using cystamine as a cross-linker, or by drop-casting. The immobilized CNDs were covalently modified with the phenothiazine Azure A via electron transfer chemistry; in particular via reactions with aryl diazonium salts. The reaction mechanism for the diazonium functionalization of CNDs was investigated. Spectroelectrochemistry experiments confirmed that electrografting, rather than adsorption, governs the functionalization of CNDs with Azure A. Finally, the application of these CNDs as electrocatalysts for the oxidation of hydrazine was demonstrated.
