Kinetics of elastic recovery in roll compaction.

Elastic recovery ( ) has been investigated and discussed extensively in the field of tableting. However, until now only limited data is available regarding in roll compaction. Therefore, a previously established in-line measurement technique was rolled out to further investigate the kinetics of in roll compaction and the effects of specific compaction force ( ) and roll speed ( ).

Ceftazidime-Avibactam Improves Outcomes in High-Risk Neutropenic Patients with Carbapenemase-Producing Enterobacterales Bacteremia.

Few studies have evaluated the efficacy of ceftazidime-avibactam (CA) for carbapenemase-producing Enterobacterales bacteremia (KPC-PEB) in high-risk neutropenic patients. This is a prospective multicenter observational study in high-risk neutropenic patients with multi-drug resistant Enterobacterales bacteremia. They were compared according to the resistance mechanism and definitive treatment provided: KPC-CPE treated with CA (G1), KPC-CPE treated with other antibiotics (G2), and patients with ESBL-producing Enterobacterales bacteremia who received appropriate definitive therapy (G3).

Laser Triangulation Based In-Line Elastic Recovery Measurement for the Determination of Ribbon Solid Fraction in Roll Compaction.

Process Analytical Technology (PAT) plays a crucial role in the design of today's manufacturing lines as continuous manufacturing becomes more important. Until now PAT tools to measure the ribbon solid fraction (SF) in-line are not commonly used in roll compaction. The aim of this study was therefore to establish a new approach as PAT for in-line ribbon solid fraction determination.

Development of a Clinical Score to Stratify the Risk for Carbapenem-Resistant Enterobacterales Bacteremia in Patients with Cancer and Hematopoietic Stem Cell Transplantation.

Identifying the risk factors for carbapenem-resistant Enterobacterales (CRE) bacteremia in cancer and hematopoietic stem cell transplantation (HSCT) patients would allow earlier initiation of an appropriate empirical antibiotic treatment. This is a prospective multicenter observational study in patients from 12 centers in Argentina, who presented with cancer or hematopoietic stem-cell transplant and developed Enterobacterales bacteremia. A multiple logistic regression model identified risk factors for CRE bacteremia, and a score was developed according to the regression coefficient.

Influence of Roll Speed during Roll Compaction and Its Effect on the Prediction of Ribbon Solid Fraction.

Influence of the roll speed () during roll compaction on ribbon, granule, tablet properties and its effect on the prediction of the ribbon solid fraction at-gap is often neglected or controversially discussed. The aim of this study was to investigate the effect of the systematically. Microcrystalline cellulose () and lactose were compressed at several maximum roll pressures () and combinations using a gap-controlled roll compactor.

Expression of renin-angiotensin system components in the early bovine embryo.

The renin-angiotensin system (RAS), mainly associated with the regulation of blood pressure, has been recently investigated in female reproductive organs and the developing foetus. Angiotensin II (Ang II) influences oviductal gamete movements and foetal development, but there is no information about RAS in the early embryo. The aim of this study was to determine whether RAS components are present in the pre-implantation embryo, to determine how early they are expressed and to investigate their putative role at this stage of development.

Cellular localization of aquaporins along the secretory pathway of the lactating bovine mammary gland: an immunohistochemical study.

In this study we examined the cellular localization of aquaporins (AQPs) along the secretory pathway of actively lactating bovine mammary glands using immunohistochemistry. Mammary tissues examined included secretory ducts and acini, gland cisterns, teats, stromal and adipose tissues. Aquaporin 1 (AQP1) was localized in capillary endothelia throughout the mammary gland in addition to myoepithelial cells underlying teat duct epithelia.

Extracellular matrix of the corpus luteum.

The potential importance of the extracellular matrix to luteal formation and development, additional development in response to pregnancy hormones in some species, and luteal function and regression is possibly under-appreciated. Collagens I and III and fibronectin change dynamically during the formation of the corpus luteum and probably reflect the necessity for directional migration of cells in the establishment of a vascularized corpus luteum. Extracellular proteins may also be essential for the maintenance of luteal cell phenotype.

Biodegradable PLGA microparticles for sustained release of a new GnRH antagonist: part II. In vivo performance.

Poly (DL-lactide-co-glycolide) microparticles (MP) containing a highly potent peptidic gonadotropin releasing hormone antagonist (degarelix) of interest in the prostate cancer indication were screened for biological performance. Efficacy was tested in a castrated male rat model at 3 doses (0.4, 1.

Biodegradable microparticles for sustained release of a new GnRH antagonist--part I: Screening commercial PLGA and formulation technologies.

The formulation of a new GnRH antagonist (degarelix) in biodegradable poly(DL-lactide-co-glycolide) (PLGA) microparticles was investigated for the development of a 3-month sustained release formulation to treat prostate cancer. The aim was to screen formulation technologies and distinct copolymers to produce microparticles (MP) of different types with good entrapment efficiency (>85%) and peptide purity (>95%) after gamma sterilization. Basically, three types of degarelix-loaded MP (4, 8 and 16% w/w nominal content) were produced with solvent and non-solvent technologies, namely double-emulsion solvent evaporation, spray-drying and two extrusion methods.
