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.

Synthesis of coral-like structures of Pr-Yb co-doped YIG: Structural,optical, magnetic and antimicrobial properties

Coral-like structures of the Y_(3-x)Pr_(x)Fe_(5-y)Yb_(y)O_(12),(0.00 ≤ x ≤ 0.04, 0.00 ≤ y ≤ 0.02) compound were synthesized using the sol-gel method. Structural investigation certified the YIG cubic crystal structure formation, without any secondary phase. It is shown that, the relatively large ionic radius of the dopant cations results in an expansion of the lattice parameter, variations in the Iona-O-Iondangle, Iona-O,Iond-O and Ionc-O bond distances and decrease in the average crystallite size. Fourier transform infrared(FTIR) and Raman measurements are essential to testify the single-phase formation of YIG crystal structure and are observed changes in the stretching and vibrational modes, respectively. The morphological study, energy dispersive spectroscopy(EDS) spectra and textural properties show corallike structures, peaks associated with Pr^(3+) and Yb^(3+) atoms and the effect of dopants on surface area,diameter, and pore volume, respectively. The optical analysis from diffuse reflectance spectra witnessed an increase in the optical gap band, a decrease in Urbach energy and blue shift in the charge transfer,correlated with the expansion of the unit cell due to the dopant's insertion in the YIG structure. A typical ferrimagnetic behavior is exhibited by the Y_(3-x)Pr_(x)Fe_(5-y)Yb_(y)O_(12)compound. The saturation magnetization(M_(s)), cubic anisotropy constant(K_(1)) and coercive field(H_(c)) increase with the Pr^(3+)cations content, as consequence of their magnetic nature and distribution around of Fe^(3+)ions due to the coexistence with the Yb^(3+). Finally, for the first time, antibacterial tests by mean of the direct contact method were performed for YIG co-doped with Pr^(3+)and Yb^(3+)and it is shown that, relatively high dosages of Pr^(3+) cations favored the activity against S. aureus, therefore, a new biological property for YIG doped with rare earths is presented.

Post Episiotomy Morbidity among Parturient in Alex Ekwueme federal university Teaching Hospital Abakaliki, Ebonyi State

引用

Open Journal of Obstetrics and Gynecology 2024年第8期14卷 1144-1160页

作者： John Chinedu Obasi Ayodele Adegbite Olaleye Boniface N. Ejikeme John O. Egede Charles Nwambeke Edene Enemma Christian Enemma Victor Onuchukwu Emmanuel Onyekelu Nathan C. Ekpe Wendy Oliobi Emmanuel C. Uwakwe Department of Obstetrics and Gynaecology Alex Ekwueme Federal University Teaching Hospital AbakalikiNigeria

Background: Episiotomy is a very common obstetric surgery, and it could be associated with serious complications. However, these complications largely are not noticed due to the shift of attention from mother to baby, after a successful delivery. Objective: To identify the morbidities associated with episiotomies and factors associated with such morbidities. Method: This was a questionnaire based cross sectional descriptive study among women who attended the Obstetric Department of Alex Ekwueme federal university Teaching Hospital Abakaliki Ebonyi State, between 1st July and 31st Nov, 2023. The study population consisted of parturients who had episiotomies in their previous confinements, attending either the antenatal clinic or the postnatal clinic at Alex Ekwueme federal university Teaching Hospital Abakaliki Ebonyi State. Results: Macrosomia was the most common indication of episiotomy at a rate of 31.6%. The majority of episiotomies were performed on the parturients in their first confinement at a rate of 64.5% and the majority of repairs were performed by the Registrar at a rate of 65.0%. Informed consent was obtained from 45.79% of parturients while 54.21% were not informed before the episiotomy was administered. Only 55.3% of the parturient received analgesia before episiotomy was administered. The majority of the parturients had their episiotomy repaired between 10 - 15 minutes at a rate of 40.3%. Postoperative pain at the rate of 44.5% was the most common complication and dyspareunia as a form of sexual complication was the commonest at a rate of 31.3%. Conclusion: The parturient needs to be properly counselled before administration of episiotomy and adequate analgesia should be given, as episiotomy is a surgical procedure. Proper training of health workers on both the technique of administering and repairing episiotomy is important. Restrictive use of routine episiotomy in primigravidae is advised to reduce the rate of episiotomy.
