RGENs are derived from the type II CRISPR (clusters of regularly interspaced palindromic repeats)/Cas (CRISPR-associated) system, an adaptive immune response in bacteria and archaea (Wiedenheft et al. 2012). Cas9, the protein component derived from Streptococcus pyogenes, forms an active nuclease when complexed with transactivating CRISPR RNA (tracrRNA) and CRISPR RNA (crRNA) (Jinek et al. 2012), which are transcribed from the CRISPR sequence encoded in the bacterial genome. This ribonucleoprotein protects host cells from invading phages or plasmids by recognizing and cleaving the DNA sequence corresponding to the crRNA sequence. Recently, we and others have exploited this system to induce site-specific DSBs, thereby modifying genomes in a targeted manner in cells and organisms (Chang et al. 2013; Cho et al. 2013a,b; Cong et al. 2013; Ding et al. 2013; Gratz et al. 2013; Hwang et al. 2013; Jiang et al. 2013; Jinek et al. 2013; Mali et al. 2013b; Shen et al. 2013; Wang et al. 2013).
Mutation frequencies at on-target and potential off-target sites of the C4BPB- and CCR5-specific RGENs in K562 cells. (A,B) Cells were transfected with crRNA, tracrRNA, and the Cas9 plasmid or the Cas9 plasmid alone (negative control). PCR amplicons that span the on-target site and potential off-target sites were subjected to deep sequencing. Sequences that contained indels around the expected cleavage site were considered to be RGEN-induced mutations. Mismatched bases are shown in red. The PAM sequence is shown in blue. (C) In vitro cleavage assay of on-target or potential off-target sequences by the CCR5-specific RGEN. Plasmids that contain putative off-target (upper) or hybrid (middle) sequences were digested with the recombinant Cas9 protein complexed with crRNA and tracrRNA. Asterisks indicate cleaved DNA bands. (Bottom) DNA sequences of the on-target, off-target, and hybrid sites.

Mutation frequencies at CCR5 on-target sites and CCR2 off-target sites. K562 cells were transfected with RGENs that target nine different sites. PCR amplicons that span the on-target and off-target sites were subjected to deep sequencing.
Comparison of guide RNA structure. Mutation frequencies of the RGENs reported in Fu et al. (2013) were measured at on-target and off-target sites using the T7E1 assay. K562 cells were cotransfected with the Cas9-encoding plasmid and the plasmid encoding GX19 sgRNA or GGX20 sgRNA. Off-target sites (OT1-3, etc.) are labeled as in Fu et al. (2013).
DNA splicing induced by paired Cas9 nickases. (A) The target sites of paired nickases in the human AAVS1 locus. The distances between the AS2 site and each of the other sites are shown. Arrows indicate PCR primers. (B) Genomic deletions detected using PCR. Asterisks indicate deletion-specific PCR products. (C) DNA sequences of deletion-specific PCR products obtained using AS2 and L1 sgRNAs. Target site PAM sequences are shown in red, and sgRNA-matching sequences are shown in capital letters. Intact sgRNA-matching sequences are underlined. (D) A schematic model of paired Cas9 nickase-mediated chromosomal deletions. Newly synthesized DNA strands are shown in red.
Paired Cas9 nickases do not induce translocations. (A) Schematic overview of chromosomal translocations between the on-target and off-target sites. (B) PCR amplification to detect chromosomal translocations. (C) Translocations induced by Cas9 nucleases but not by the nickase pair.
In this study, we showed that RGENs do indeed induce off-target mutations at sites with a single-base mismatch. We found, however, that RGENs efficiently discriminate on-target sites from off-target sites that differ by only two bases. Furthermore, exome sequencing showed that no off-target mutations were present in four clonal populations of mutant cells. Our results suggest that one could avoid or minimize off-target effects of RGENs by choosing unique target sites that do not have any homologous sequences elsewhere in the genome, a strategy we had used to avoid off-target effects of TALENs (Kim et al. 2013a). We also found that the structure and composition of guide RNA can be modified to reduce off-target mutations. We cannot rule out the possibility that the 11 RGENs we created in this study induce off-target mutations at sites not examined here, which could be revealed by deep sequencing at other less-homologous candidate sites or by whole genome sequencing. In addition, in vitro selection of cleavage sites (Pattanayak et al. 2011) or the IDLV capture approach (Gabriel et al. 2011) used for the identification of ZFN off-target sites may reveal cryptic sites cleaved by RGENs, although it is difficult to imagine that RGENs recognize off-target sites that are not complementary to crRNA sequences at an appreciable level. It is also worth noting that RGENs cleave DNA much less discriminatingly in vitro than they do in cells (Fig. 1C), limiting the in vitro selection method.
Domestic protests have dominated the headlines in Israel in recent weeks, as strikes over the high cost of living have spread across the country. But while the local media have termed it Israel's own Arab Spring, the protesters say they are far from calling for revolution.
The demonstration started with one young woman pitching a tent to protest the high cost of rent in Tel Aviv. Now, several hundred tents crowd the boulevard. Similar protests have sprung up across the country, with tent cities in more than a dozen places.

I'm building a C# application that loads a 32-bit COM dll. The compiled application runs fine on 32-bit Windows but barfs on 64 bit Windows because it can't load the 32-bit COM. Is there a way to set a 32-bit build target in VC# 2008 Express Edition?
The research examined fees charged by four major insurers for colonoscopies in all 50 states and Washington. It found that facility fees were about 55 percent higher at hospitals than at surgery centers when controlling for insurer, location and fee type.
Luxury brands are those that offer products or services associated with rarity, excellence, and high prices. They are often seen as status symbols and are popular among high-net-worth individuals (HNWI) and aspirational consumers. Luxury brands operate in markets such as designer fashion, jewelry, cars, hotels, events, cuisine, cosmetics, and travel.
Luxury brands target high-net-worth individuals (HNWI) and aspirational consumers who are willing to pay a premium to own exclusive, high-quality products. These consumers are by nature hard to find, so data-driven approaches help identify and entice them by speaking to their aspirations and values.
Luxury brands must create a sense of exclusivity to attract their target audience. Strategies may include offering limited edition products or restricting availability, hosting exclusive events, or providing personalized services.
Maintaining a strong brand image and reputation is crucial for luxury brands to justify their high prices. This requires careful management and positioning of various brand touchpoints, like advertising, product design, customer service, and online presence. Luxury brands often have a well-defined identity that resonates with their target audience and sets them apart.
Sometimes pricing itself can be a marketing tactic. Luxury brands leverage their high prices to create a prestigious image. This appeals to customers, who are more inclined to pay a premium for the bragging rights that come with scarcity. This strategy comes with risks, as affluent consumers can be price sensitive too.
The 4 E's of luxury marketing are a framework created by luxury marketing expert Michel Chevalier. It provides a guideline for luxury brands to create effective marketing strategies that appeal to their target audience.
California Greenhouse Gas Emissions from 2000 to 2021: Trends of Emissions and Other Indicators summarizes and highlights the major annual changes and notable longer-term trends of each year's GHG inventory. It provides easy-to-read graphs and explanations to illuminate California's progress in its commitment to reduce climate-changing emissions.
California's annual statewide greenhouse gas (GHG) emission inventory is an important tool for establishing historical emission trends and tracking California's progress in reducing GHGs. In concert with data collected through various California Global Warming Solutions Act (AB 32) programs, the GHG inventory is a critical piece in demonstrating the state's progress in achieving the statewide GHG target. The inventory provides estimates of anthropogenic GHG emissions within California, as well as emissions associated with imported electricity; natural sources are not included in the inventory. CARB is responsible for maintaining and updating California's GHG Inventory per H&SC section 39607.4.
The inventory includes estimates for carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases with high global warming potentials (High-GWP) which includes hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3). It uses an inventory scope and framework consistent with international and national GHG inventory practices. An updated emission inventory is published annually to include additional years and improved estimation methods. Archives of all previous inventory data and documentation are available on the archive page.
