Involvement of glyphosate in disruption of biotransformation P450 enzymes and hepatic lipid metabolism in chicken

The current study investigated the potentially harmful consequences of pure glyphosate or Roundup® on CYP family members and lipid metabolism in newly hatched chicks. On the sixth day, 225 fertilized eggs were randomly divided into three treatments: (1) the control group injected with deionized water, (2) the glyphosate group injected with 10 mg pure glyphosate/Kg egg mass and (3) the Roundup group injected 10 mg the active ingredient glyphosate in Roundup®/Kg egg. The results of the study revealed a reduction in hatchability in chicks treated with Roundup®. Moreover, change of Lipid concentration in serum and the liver-treated groups. Additionally, increased liver function enzymes and increased oxidative stress in the glyphosate and Roundup® groups. Furthermore, liver tissues showed histological changes and several lipid deposits in glyphosate-treated groups. Hepatic CYP1A2 and CYP1A4 expressions were significantly increased (p < .05) after glyphosate exposure, and suppression of CYP1C1 mRNA expression was significant (p < .05) after Roundup® exposure. The pro-inflammatory cytokines genes IFN-γ and IL-1β expression were significantly increased (p < .05) after Roundup® exposure. In addition, there were significant differences in the levels of expression genes which are related to lipid synthesis or catabolism in the liver. In conclusion, in ovo glyphosate exposure caused disruption of biotransformation, pro-inflammatory and lipid metabolism in chicks.

Waste cooking oil processing over cobalt aluminate nanoparticles for liquid biofuel hydrocarbons production

The catalytic conversion of waste cooking oil (WCO) was carried out over a synthetic nano catalyst of cobalt aluminate (CoAl₂O₄) to produce biofuel range fractions. A precipitation method was used to create a nanoparticle catalyst, which was then examined using field-emission scanning electron microscopy, X-ray diffraction, energy dispersive X-ray, nitrogen adsorption measurements, high-resolution transmission electron Microscopy (HRTEM), infrared spectroscopy, while a gas chromatography-mass spectrometer (GC-MS) was used to analyze the chemical construction of the liquid biofuel. A range of experimental temperatures was looked at including 350, 375, 400, 425, and 450 °C; hydrogen pressure of 50, 2.5, and 5.0 MPa; and liquid hour space velocity (LHSV) of 1, 2.5, and 5 h^-1. As temperature, pressure, and liquid hourly space velocity increased, the amount of bio-jet and biodiesel fractional products decreased, while liquid light fraction hydrocarbons increased. 93% optimum conversion of waste cooking oil over CoAl₂O₄ nano-particles was achieved at 400 °C, 50 bar, and 1 h^-1 (LHSV) as 20% yield of bio-jet range,16% gasoline, and 53% biodiesel. According to the product analysis, catalytic hydrocracking of WCO resulted in fuels with chemical and physical characteristics that were on par with those required for fuels derived from petroleum. The study's findings demonstrated the nano cobalt aluminate catalyst's high performance in a catalytic cracking process, which resulted in a WCO to biofuel conversion ratio that was greater than 90%. In this study, we looked at cobalt aluminate nanoparticles as a less complex and expensive alternative to traditional zeolite catalysts for the catalytic cracking process used to produce biofuel and thus can be manufactured locally, which saves the cost of imports for us as a developing country.

Taeniectomy pouch as neorectum after low rectal resection

Background and purpose The functional outcomes of incontinence and high stool frequency resulting from restorative surgery are often criticised. The aim of this study was to assess the taeniectomy pouch in comparison with other pouches described in the literature. Material and methods This was a prospective cohort study. All patients who were candidate for low rectal resection presenting to the colorectal unit at Cairo University hospitals during the period February 2013 to February 2015 were included in the study (90 patients). Safety and feasibility of the new technique were assessed, including operative time, leakage, postoperative urgency, incontinence, number of daily motions and difficulty in evacuation. These parameters were assessed clinically, by means of defecography and anorectal manometry. Results The mean age of patients was 49.6 years. Percentages of postoperative mortality and leakage were 2.2% and 3.4%, respectively. Mean operative time was 117 minutes. Mean numbers of daily motions were 3.04 and 1.52 at 3 and 12 months, respectively. Mean Wexner score for continence at 3 and 12 months were 3.21 and 1.32, respectively. Mean resting pressure was 51.63 mmHg, squeeze pressure was 130.42 mmHg and mean threshold volume was 118.68 ml. Conclusions Taeniectomy is a novel technique for pouch formation after low rectal resection, which can be used as an alternative to other pouches, especially the widely used transverse coloplasty.

Placental villous maturation in patients with repeated abortions and chronic toxoplasmosis

The conceptions products obtained from 20 patients with repeated abortions and chronic toxoplasmosis were examined histopathologically comparing the results with those of ten Toxoplasma seronegative patients. The results showed significant association between chronic toxoplasmosis and diffuse failure of growth of placental villi.
