Brown adipose tissue (BAT) is responsible for thermogenesis that is not associated with shivering through the process of converting chemical energy into heat through uncoupling protein 1 (UCP1) in the mitochondria. Thus, expanding or activating BAT could be a potential tool against obesity. To analyze the effect of kinase signaling on brown adipocyte formation, a process that describes the acquisition of the ability to dissipate energy as heat, we performed lentiviral-mediated short hairpin knockdown or used pharmacological inhibitors in a high-content and high-throughput in vitro image-based screen...

Tagetes erecta could thrive well in phytotoxic levels of Cd (50-300 mg kg(-1) ) and Cu (150-400 mg kg(-1) ) for 21 days. It accumulated high metal contents in its above ground tissues (3675 mg Cd kg(-1) DW and 3948 mg Cu kg(-1) DW), showed greater root to shoot translocation and high extraction coefficient; all of which pointed towards its potential as a hyperaccumulator. Both Cd and Cu stress reduced the plant biomass, foliar area, and number. Besides, there were significant declines in pigment contents as well as boosts in lipid peroxidation levels...

BACKGROUND: Self-collection has been proposed as a strategy to increase cervical screening coverage among hard-to-reach women. However, evaluations of the implementation of this strategy on a large scale are scarce. This paper describes the process and measurement of the scaling-up of self-collection offered by community health workers during home visits as a strategy to reach under-screened women aged 30+ with public health coverage, defined as the target women. METHODS: We used an adaptation of the Health System Framework to analyze key drivers of scaling-up...

We have developed a good manufacturing practice for long-term cultivation of fetal human midbrain-derived neural progenitor cells. The generation of human dopaminergic neurons may serve as a tool of either restorative cell therapies or cellular models, particularly as a reference for phenotyping region-specific human neural stem cell lines such as human embryonic stem cells and human inducible pluripotent stem cells. We cultivated 3 different midbrain neural progenitor lines at 10, 12, and 14 weeks of gestation for more than a year and characterized them in great detail, as well as in comparison with Lund mesencephalic cells...

Due to their inherent nature, DNA strands can be easily broken by various environmental factors including chemical agents and ionizing radiation. Unrepaired DNA double-stranded breaks (DSBs) may result in genetic instability and have a strong negative impact on the integrity of the genome. It has been found that DSBs are always followed by phosphorylation of histone protein H2AX, a member of the H2A family, and immunocytochemical detection of phosphorylated H2AX (referred to as γ-H2AX) is one of the frequently used techniques for assessing DNA damage...

X-chromosome inactivation is a mechanism of dosage compensation in which one of the two X chromosomes in female mammals is transcriptionally silenced. Once established, silencing of the inactive X (Xi) is robust and difficult to reverse pharmacologically. However, the Xi is a reservoir of >1,000 functional genes that could be potentially tapped to treat X-linked disease. To identify compounds that could reactivate the Xi, here we screened ∼367,000 small molecules in an automated high-content screen using an Xi-linked GFP reporter in mouse fibroblasts...

Background and Aims: Drug-induced steatosis is a major reason for drug failure in clinical trials and post-marketing withdrawal; and therefore, predictive biomarkers are essential. These could be particularly relevant in non-alcoholic fatty liver disease (NAFLD), where most patients show features of the metabolic syndrome and are prescribed with combined chronic therapies, which can contribute to fatty liver. However, specific biomarkers to assess the contribution of drugs to NAFLD are lacking. We aimed to find microRNAs (miRNAs) responsive to steatotic drugs and to investigate if they could become circulating biomarkers for drug-induced steatosis...

Cryptosporidiosis has emerged as a leading cause of non-viral diarrhea in children under five years of age in the developing world, yet the current standard of care to treat Cryptosporidium infections, nitazoxanide, demonstrates limited and immune-dependent efficacy. Given the lack of treatments with universal efficacy, drug discovery efforts against cryptosporidiosis are necessary to find therapeutics more efficacious than the standard of care. To date, cryptosporidiosis drug discovery efforts have been limited to a few targeted mechanisms in the parasite and whole cell phenotypic screens against small, focused collections of compounds...

Municipal wastewater (WW), if not properly remediated, poses a threat to the environment and human health by carrying significant loads of nutrients and pathogens. These contaminants pollute rivers, lakes and natural reservoirs where they cause eutrophication and pathogen-mediated diseases. However, the high nutrient content of WW makes it an ideal environment for remediation with microalgae that require high nutrient concentrations for growth and are not susceptible to toxins and pathogens. Given that an appropriate algal strain is used for remediation, the incurred biomass can be refined for the production of biofuel...

Taxanes represent some of the most commonly used chemotherapeutic agents for ovarian cancer treatment. However, they are only effective in approximately 40% of patients. Novel therapeutic strategies are required to potentiate their effect and improve patient outcome. A hallmark of many cancers is the constitutive activation of the PI3K/AKT pathway, which drives cell survival and metabolism. We discovered a striking decrease in AKT activity coupled with a significant reduction in glucose 6-phosphate and ATP levels during mitotic arrest in the majority of ovarian cancer cell lines tested, indicating a potential metabolic vulnerability...

A multiparametric, live-cell, high-content-screening (HCS) cytotoxicity assay was first demonstrated in 2006 (Arch Toxicol 80, 580-604) to be highly concordant with human hepatotoxicity, including idiosyncratic hepatotoxicities, and other target organ toxicities, in contrast to historical assays. The success of the assay was attributed to its simultaneous measurement of multiple, appropriate "cytobiomarkers; use of human cells with xenometabolic competence for toxicities mediated by metabolites, 72-hour exposure to enable expression of slower-acting toxicants, exposure to a wide-range of concentrations, up to 30- to 100-fold the efficacious concentration, and normalising the in vitro cytotoxic concentration to an estimate of the in vivo concentration of exposure...

The flipped classroom was utilized in a two-semester, high-content science course that enrolled between 50 and 80 students at a small liberal arts college. With the flipped model, students watched ~20-min lectures 2 days/wk outside of class. These videos were recorded via screen capture and included a detailed note outline, PowerPoint slides, and review questions. The traditional format included the same materials, except that lectures were delivered in class each week and spanned the entire period. During the flipped course, the instructor reviewed common misconceptions and asked questions requiring higher-order thinking, and five graded case studies were performed each semester...

Association mapping is usually performed by testing the correlation between a single marker and phenotypes. However, because patterns of variation within genomes are inherited as blocks, clustering markers into haplotypes for genome-wide scans could be a worthwhile approach to improve statistical power to detect associations. The availability of high-density molecular data allows the possibility to assess the potential of both approaches to identify marker-trait associations in durum wheat. In the present study, we used single marker- and haplotype-based approaches to identify loci associated with semolina and pasta colour in durum wheat, the main objective being to evaluate the potential benefits of haplotype-based analysis for identifying quantitative trait loci...
