This work describes a simple yet powerful scalable solution chemistry strategy to create back‐contact rich interfaces between substrates such as commercial transparent conducting fluorine‐doped tin oxide coated glass(FTO)and photoactive thin films such as hematite for low‐cost water oxidation ***‐resolution electron microscopy(SEM,TEM,STEM),atomic force microscopy(AFM),elemental chemical mapping(EELS,EDS)and photoelectrochemical(PEC)investigations reveal that the mechanical stress,lattice mismatch,electron energy barrier,and voids between FTO and hematite at the back‐contact interface as well as short‐circuit and detrimental reaction between FTO and the electrolyte can be alleviated by engineering the chemical composition of the precursor solutions,thus increasing the overall efficiency of these low‐cost photoanodes for water oxidation reaction for a clean and sustainable generation of hydrogen from PEC water‐*** findings are of significant importance to improve the charge collection efficiency by minimizing electron‐hole recombination observed at back‐contact interfaces and grain boundaries in mesoporous electrodes,thus improving the overall efficiency and scalability of low‐cost PEC water splitting devices.

Complexed amino acid minerals vs. bis-glycinate chelated minerals:Impact on the performance of old laying hens

引用

Animal Nutrition 2024年第1期16卷 395-408页

作者： Marcos J.B.Santos Maria C.M.M.Ludke Leandro M.Silva carlos B.V.Rabello Mércia R.Barros Fabiano S.costa Clariana S.Santos Jamille S.S.Wanderley Department of Animal Science Rural Federal University of Pernambuco Department of Veterinary Science Rural Federal University of Pernambuco

The present study was to evaluate the effect of trace minerals(Zn, Mn, and Cu) from complexed amino acid minerals(ZMCAA) and bis-glycinate chelated minerals(ZMCGly) in laying hen diets on performance,internal and external egg quality, yolk mineral deposition, intestinal morphometry, and bone characteristics. From 78 to 98 weeks of age, 400 White LSL-Lite strain laying hens were distributed in a randomized design with 4 treatments with 10 replicates per treatment. Treatments were distributed in a 2 ×2 factorial arrangement using either Zn, Mn, and Cu of ZMCAA or ZMCGly source at 2 levels: low(20, 20,and 3.5 mg/kg of Zn, Mn, and Cu, respectively) or high(40, 40, and 7 mg/kg of Zn, Mn, and Cu,respectively). The analysis of variance was performed, and in cases where differences were observed, the means were compared using Tukey?s test(P < 0.05). The source and level of trace mineral supplementation had a significant impact on the performance of laying hens. Hens fed ZMCAA had higher egg production(P = 0.01), egg weight(P = 0.02), egg mass(P = 0.01), and lower feed conversion ratio(P =0.05) compared to those fed ZMCGly. The ZMCAA supplementation showed higher albumen height(P =0.01), albumen weight(P = 0.01), and eggshell thickness(P < 0.01). The deposition of Zn(P < 0.01), Mn(P< 0.01), and Cu(P < 0.01) in the egg yolk was greater for hens received ZMCAA. Tibia weight(P = 0.04)and bone densitometry(P < 0.01) in the tibia were higher with ZMCAA supplementation. In the small intestine, ZMCAA resulted in longer villi(P = 0.02) and shorter crypt depth(P = 0.01) in the *** and ileum measurements were influenced by the level and source of trace minerals(P < 0.05).Laying hens fed ZMCAA exhibited superior performance, egg quality, deposition of trace minerals in the egg yolk, and bone density compared to hens fed ZMCGly. In this study, older laying hens supplemented with ZMCAA at lower levels demonstrated adequate levels of supplementation.

Severe SARS-CoV-2 Infection: Late Impact on the Retinal Ganglion Cell Layer Thickness

Open Journal of Ophthalmology 2024年第3期14卷 339-349页

作者： Rayssa de Fátima Farias da costa Gabino carlos Teixeira Brandt Sebastião Cronemberger UNIFACISA Campina Grande Paraba Brazil Federal University of Minas Gerais Belo Horizonte Brazil

Purpose: The involvement of the ocular anterior segment by SARS-CoV-2 has been the subject of many studies, however, the repercussions on the posterior segment, particularly on the different layers of the retina and optic nerve, are still little known. The purpose of this study was to evaluate the impact of severe COVID-19 on the retinal ganglion cell layer (RGCL) thickness. Methods: This observational, prospective and analytical study was performed in the Ophthalmology Department of the FACISA University Center, Campina Grande. Three groups were included: group I (control), 29 healthy individuals who had not severe COVID-19;group II (infirmary), 24 individuals who had COVID-19 and were hospitalized in the infirmary;and group III, 25 individuals who had severe COVID-19 and required Intense Care Unit (ICU). All individuals had ophthalmologic examination and assessment of RGCL thickness using Optical Coherence Tomography (OCT). Statistical tests required p ≤ 0.05 to reject the null hypothesis. Results: The mean of RGCL thickness was significantly reduced in individuals from GIII (77.9 ± 8.9 µm), as compared with GII (83.9 ± 10.9 µm) and GI (82.8 ± 6.5 µm) (p = 0.0027). The mean measurements from the retinal neve fiber layer (RNFL) of the optic nerve head were similar. However, when evaluated sectoral, the mean of RNFL at the temporal sector of the optic disc was significantly lower in group GIII (p Conclusion: The RGCL thickness from patients with severe COVID-19 was significantly reduced. This finding supports that the SARS-CoV-2 has systemic action and affinity for nerve cells, including those from the retina and are related to the severity of the infection.

The incidence of Mycobacterium avium complex pulmonary disease (MACPD) has been globally increasing. The present study aims to provide a comprehensive analysis of clinical characteristics and treatment response among patients in the Amazon region of Brazil and conduct a retrospective cohort study at a prominent referral hospital in the State of Par, Brazil, from 2012 to 2020. The M. avium group represented 58.9% of cases, followed by M. intracellulare (35.7%), M. colombiense (3.6%), and M. chimaera (1.8%). The majority of patients (73.2%) were female and with an average age of 63 years. Primary clinical manifestations included persistent cough and sputum production. The Charlson comorbidity index (CCI) averaged 2.47, with 36.3% of patients having a CCI score equal to higher than 3. Notably, over 70% of patients had received treatment for pulmonary tuberculosis before initiating treatment for MAC infection. The fibrocavitary radiologic form was the most prevalent (55.4%), frequently exhibiting a bilateral distribution (53.6%). Antimicrobial susceptibility revealed a significant prevalence of MAC resistance to drugs in the therapeutic regimen. Despite this, most of the patients experienced clinical improvement (50%). In conclusion, this study highlights a higher prevalence of MAC infections among middle-aged women, with a history of pulmonary tuberculosis treatment and presenting the fibrocavitary radiological form was predominant.
