Novel method of measurement of in vitro drug uptake in OATP1B3 overexpressing cells in the presence of dextran.

Background: In predictions about hepatic clearance (CL), a number of studies explored the role of albumin and transporters in drug uptake by liver cells, challenging the traditional free-drug theory. It was proposed that liver uptake can occur for transporter substrate compounds not only from the drug's unbound form but also directly from the drug-albumin complex, a phenomenon known as uptake facilitated by albumin. In contrast to albumin, dextran does not exhibit binding properties for compounds.

Quality of life and anxiety 12 and 36 months after surgical SUI treatment in postmenopausal women.

SUI can be treated with medication, behavioral changes, pelvic floor muscle exercises, or surgical intervention. This study aimed to assess the changes in quality of life, acceptance of illness, and impact on physical activity, in patients after the transobturator tape (TOT) procedure following long-term assessment.

Genome-Editing of for Alteration of Starch Granule Size in Potato Tubers.

Genome-editing has enabled rapid improvement for staple food crops, such as potato, a key beneficiary of the technology. In potato, starch contained within tubers represents the primary product for use in food and non-food industries. Starch granules are produced in the plastids of tubers with plastid size correlated with the size of starch grana.

Cystic dilatation of umbilical cord associated with patent urachus.

An urachus is a remnant of allantois in embryo development constituting a connection between the dome of the bladder and umbilicus. It develops on day 16 after conception and closes during the pregnancy to form the median umbilical ligament. Patent urachus results from a failure in closing its lumen in 10-12 gestational weeks.

Case Studies of Geothermal System Response to Perturbations in Groundwater Flow and Thermal Regimes.

Global demands for energy-efficient heating and cooling systems coupled with rising commitments toward net zero emissions is resulting in wide deployment of shallow geothermal systems, typically installed to a depth of 100 to 200 m, and in the continued growth of the global ground source heat pump (GSHP) market. Ground coupled heat pump (GCHP) systems take up to 85% of the global GSHP market. With increasing deployment of GCHP systems in urban areas coping with limited regulations, there is growing potential and risk for these systems to impact the subsurface thermal regime and to interact with each other or with nearby heat-sensitive subsurface infrastructure.

Hemiarthroplasty for Femoral Neck Fractures in the Elderly: A Comparison of Cemented and Uncemented Femoral Stems.

The incidence of displaced femoral neck fractures among elderly patients is increasing as the population ages.Historically, the preferred treatment for displaced femoral neck fractures in elderly patients has been hemiarthroplasty with use of cemented fixation of the implant. However, there is evidence that this technique may be associated with fat embolization and subsequent cardiopulmonary arrest in the early postoperative period.

Realizing the "40 by 2022" Commitment from the United Nations High-Level Meeting on the Fight to End Tuberculosis: What Will It Take to Meet Rapid Diagnostic Testing Needs?

The potential gains from full adoption of World Health Organization (WHO)-recommended rapid diagnostics (WRDs) for tuberculosis (TB) are significant, but there is no current analysis of the additional investment needed to reach this goal. We sought to estimate the necessary investment in instruments, tests, and money, using Xpert MTB/RIF (Xpert), which detects (MTB) and tests for resistance to rifampicin (RIF), as an example. An existing calculator for TB diagnostic needs was adapted to estimate the Xpert needs for a group of 24 countries with high TB burdens.

Multiplex CRISPR Mutagenesis of the Serine/Arginine-Rich (SR) Gene Family in Rice.

Plant growth responds to various environmental and developmental cues via signaling cascades that influence gene expression at the level of transcription and pre-mRNA splicing. Alternative splicing of pre-mRNA increases the coding potential of the genome from multiexon genes and regulates gene expression through multiple mechanisms. Serine/arginine-rich (SR) proteins, a conserved family of splicing factors, are the key players of alternative splicing and regulate pre-mRNA splicing under stress conditions.

Carboxymethylated starch and cellulose derivatives-based film as human skin equivalent for adhesive properties testing.

The films based on carboxymethyl derivatives of starch (CMS) and cellulose (CMC) were proposed as a novel human skin equivalent. The physicochemical properties (moisture absorption, solubility in water, mechanical properties) of CMS/CMC films were evaluated. Additionally, some properties were compared to the human skin ones (surface roughness, tribology).

Combined Ipsilateral Humeral Shaft and Galeazzi Fractures Creating a Floating Elbow Variant.

"Floating elbow" injuries of the arm traditionally represent a combination of humeral shaft and forearm fractures which require anatomic rigid open reduction and internal fixation of all fractures to allow for early range of motion exercises of the elbow. There are published variants of the floating elbow injury which include ipsilateral diaphyseal humeral fracture, proximal ulna fracture with proximal radioulnar joint disruption, and ipsilateral diaphyseal humeral fracture with elbow dislocation and both bones forearm fracture. We present the case of a 21-year-old woman whose left arm became caught between the side of a waterslide and adjacent rocks at a park.

The plastid genome as a chassis for synthetic biology-enabled metabolic engineering: players in gene expression.

Owing to its small size, prokaryotic-like molecular genetics, and potential for very high transgene expression, the plastid genome (plastome) is an attractive plant synthetic biology chassis for metabolic engineering. The plastome exists as a homogenous, compact, multicopy genome within multiple-specialized differentiated plastid compartments. Because of this multiplicity, transgenes can be highly expressed.

Advanced editing of the nuclear and plastid genomes in plants.

Genome editing is a powerful suite of technologies utilized in basic and applied plant research. Both nuclear and plastid genomes have been genetically engineered to alter traits in plants. While the most frequent molecular outcome of gene editing has been knockouts resulting in a simple deletion of an endogenous protein of interest from the host's proteome, new genes have been added to plant genomes and, in several instances, the sequence of endogenous genes have been targeted for a few coding changes.

Prediction of Steam Burns Severity using Raman Spectroscopy on ex vivo Porcine Skin.

Skin burns due to accidental exposure to hot steam have often been reported to be more severe than the ones occurring from dry heat. While skin burns due to flames or radiant heat have been thoroughly characterized, the mechanisms leading to steam burns are not well understood and a conundrum still exists: can second degree burns occur without destruction of the epidermis, i.e.
