Complex cesarean section: Surgical approach to reduce the risks of intraoperative complications and postpartum hemorrhage.

The incidence of cesarean section is dramatically increasing worldwide, whereas the training opportunities for obstetrician/gynecologists to manage complex cesarean section appear to be decreasing. This may be attributed to changing working hours directives and the increasing use of laparoscopy for gynecological surgical procedures, including in gynecological oncology. Various situations can create surgical difficulties during a cesarean section; however, two of the most frequent are complications from previous cesarean (myometrial defects, with or without placental intrusion and peritoneal adhesions) and the high risk of postpartum hemorrhage (uterine overdistension, abnormal placentation, uterine fibroids).

Study of the Anti-MYC Potential of Lanostane-Type Triterpenes.

One of the most investigated molecular targets for anticancer therapy is the proto-oncogene , which is amplified and thus overexpressed in many types of cancer. Due to its structural characteristics, developing inhibitors for the target has proven to be challenging. In this study, the anti-MYC potential of lanostane-type triterpenes was investigated for the first time, using computational approaches that involved ensemble docking, prediction of structural properties and pharmacokinetic parameters, molecular dynamics (MD), and binding energy calculation using the molecular mechanics-generalized born surface area (MM-GBSA) method.

The effect of genotype and sex on carcass characteristics and fatty acid profile of Pekin broiler ducks.

The aim of this study was to compare two different strains of Pekin duck and to answer one scientific hypothesis: 1) Strain and sex influence live body weight, hot and cold carcass weights and carcass portions weights and yields, fatty acid content, fatty acid total cholesterol and α-tocopherol contents of meat. The study used 50 individuals of each strain in comparison (Cherry Valley and Grimaud) equally divided between both sexes), raised in equal rearing and feeding conditions. The results show that, when raised in equal rearing and feeding conditions and slaughtered at matching age, the strain had no significant influence on live body weight at slaughter, warm and cold carcass weights.

Enhancing physicochemical properties of hydrochlorothiazide with zwitterionic L-proline and 5-fluorocytosine cocrystals through mechanochemical synthesis.

Hydrochlorothiazide (HTZ) is a thiazide-type diuretic drug approved by the FDA in 1959 for treatment of hypertension and peripheral edema and has been used since. HTZ exhibits low solubility and low permeability, leading to variable oral bioavailability and limited intestinal drug permeability. For this reason, several attempts to improve HTZ physicochemical properties have been made during the past decades.

Biochar supplementation affects the microbiome of recycled manure solids for cow bedding: a metagenomic analysis.

The widespread use of Recycled Manure Solids (RMS) as cow bedding material is not without risks, since cattle manure may act as a vehicle for pathogenic and antimicrobial resistant bacteria dissemination. Thus, our aim was to evaluate RMS-supplemented with a pine biochar produced in Portugal as a new cow bedding material, since the use of biochar has been shown to have the potential to mitigate the impact of relevant bacterial species when added to animal manure microbiota. Our experimental setup consisted on fresh RMS samples that were collected on a commercial dairy farm and placed in naturally-ventilated containers for a total of 4 groups: 1-non-supplemented RMS; 2-RMS supplemented with 2.
