Does Goal Setting Make a Better Reader?

This action research project looked at the relationship between goal setting and an increase in reading levels in six public school students in 4th and 5th grade with learning disabilities in reading. Data was collected through Individualized Education Plan progress reports and individual goals written by the students in connection with the Developmental Reading Assessment test over the fall 2018 semester. The data was compared to the 2018 spring semester IEP goal data from the previous school year when the students had not written goals

APOL1 CKD Risk Alleles in New Mexico African American and American Indian Populations: Racial Disparity

Purpose/Background: Two haplotypes of human apolipoprotein L1 gene (gene: APOL1; protein: ApoL1) harboring three coding sequence mutations have been demonstrated as risk variants associated with non-diabetic chronic kidney diseases (CKD) in African Americans. The first one, termed G1, is a two non-synonymous SNP haplotype (rs73885319 (A\u3eG; p.S342G) and rs60910145 (G\u3eT; p.I384M). The second one, termed G2, is a two codon deletion haplotype rs71785313 (6-bp in frame deletion) These two coding-sequence variants have been discovered in CKD patients of African ancestry and linked to the pathogenesis of primary focal and segmental glomerulosclerosis (FSGS), hypertension-attributed kidney disease, and HIV-associated nephropathy (HIVAN), under a recessive inheritance pattern. Marked disparities exist in races, rates, and etiological classifications of CDK between African Americans (AAs) and European Americans. Sequencing and genotyping analysis of known APOL1 SNPs showed that only APOL1 G1 and G2 confer kidney risk, and other common and rare APOL1 missense variants, including the G3 haplotype, do not contribute to FSGS and HIVAN in the US population. According to the report of US census bureau, African American and American Indian (AI) citizens in New Mexico make up nearly 2.5% and 10.9% of the state\u27s entire population in 2018 (2). However, whether APOL1 G1 and G2 kidney-risk alleles are linked with hypertension-attributed CKD in AAs and AIs in New Mexico has not been investigated. Materials & Methods: We analyzed the published results of a retrospective analysis of inpatient and discharge data from hospitals across the state of New Mexico, known as Hospital Inpatient and Discharge Dataset (HIDD; 3). Results: A pattern persisted for all three years (2012-2014) that AAs had the highest rate of CKD followed by AIs per 10,000 population in New Mexico. AAs had the highest age adjusted rate of CKD with hypertension at 102.6 per 10,000 population (29.7% (102.6/345.7) of all CKD with hypertension patients) followed by American Indians at 91.9 (26.6% (91.9/345.7) of all CKD with hypertension patients). Interestingly, in terms of CKD with diabetes, AIs had the highest age adjusted rate at 79.9 per 10,000 followed by AAs at 66.5. Discussion/Conclusion: The prevalence of CKD with hypertension in AA and AI populations is significantly high in New Mexico, To understand the etiology of CKD in AAs and AIs in New Mexico, genotyping the APOL1 G1 and G2 risk alleles in these two populations is warranted. Detection of APOL1 associations with CKD and delineation of injury pathways (autophagy, necroptosis and ferroptosis) would bring hope for effective treatment for these kidney diseases. In addition, modifier loci can influence APOL1 risk for the development of CKD. ‘Second hits’, for example viral and environmental, may alter the outcome of APOL1 risk variants

APOBECs and Herpesviruses

The apolipoprotein B mRNA editing enzyme, catalytic polypeptide-like (APOBEC) family of DNA cytosine deaminases provides a broad and overlapping defense against viral infections. Successful viral pathogens, by definition, have evolved strategies to escape restriction by the APOBEC enzymes of their hosts. HIV-1 and related retroviruses are thought to be the predominant natural substrates of APOBEC enzymes due to obligate single-stranded (ss)DNA replication intermediates, abundant evidence for cDNA strand C-to-U editing (genomic strand G-to-A hypermutation), and a potent APOBEC degradation mechanism. In contrast, much lower mutation rates are observed in double-stranded DNA herpesviruses and the evidence for APOBEC mutation has been less compelling. However, recent work has revealed that Epstein-Barr virus (EBV), Kaposi's sarcoma-associated herpesvirus (KSHV), and herpes simplex virus-1 (HSV-1) are potential substrates for cellular APOBEC enzymes. To prevent APOBEC-mediated restriction these viruses have repurposed their ribonucleotide reductase (RNR) large subunits to directly bind, inhibit, and relocalize at least two distinct APOBEC enzymes-APOBEC3B and APOBEC3A. The importance of this interaction is evidenced by genetic inactivation of the EBV RNR (BORF2), which results in lower viral infectivity and higher levels of C/G-to-T/A hypermutation. This RNR-mediated mechanism therefore likely functions to protect lytic phase viral DNA replication intermediates from APOBEC-catalyzed DNA C-to-U deamination. The RNR-APOBEC interaction defines a new pathogen-host conflict that the virus must win in real-time for transmission and pathogenesis. However, partial losses over evolutionary time may also benefit the virus by providing mutational fuel for adaptation

Repair of a Mutation Disrupting the Guinea Pig Cytomegalovirus Pentameric Complex Acquired during Fibroblast Passage Restores Pathogenesis in Immune-Suppressed Guinea Pigs and in the Context of Congenital Infection

ABSTRACT Guinea pig cytomegalovirus (GPCMV) provides a valuable model for congenital cytomegalovirus transmission. Salivary gland (SG)-passaged stocks of GPCMV are pathogenic, while tissue culture (TC) passage in fibroblasts results in attenuation. Nonpathogenic TC-derived virus N13R10 (cloned as a bacterial artificial chromosome [BAC]) has a 4-bp deletion that disrupts GP129 , which encodes a subunit of the GPCMV pentameric complex (PC) believed to govern viral entry into select cell types, and GP130 , an overlapping open reading frame (ORF) of unknown function. To determine if this deletion contributes to attenuation of N13R10, markerless gene transfer in Escherichia coli was used to construct virus r129, a variant of N13R10 in which the 4-bp deletion is repaired. Virions from r129 were found to contain GP129 as well as two other PC subunit proteins, GP131 and GP133, whereas these three PC subunits were absent from N13R10 virions. Replication of r129 in fibroblasts appeared unaltered compared to that of N13R10. However, following experimental challenge of immunocompromised guinea pigs, r129 induced significant weight loss, longer duration of viremia, and dramatically higher (up to 1.5 × 10 6 -fold) viral loads in blood and end organs compared to N13R10. In pregnant guinea pigs, challenge with doses of r129 virus of ≥5 × 10 6 PFU resulted in levels of maternal viremia, congenital transmission, pup viral loads, intrauterine growth restriction, and pup mortality comparable to that induced by pathogenic SG virus, although higher doses of r129 were required. These results suggest that the GP129-GP130 mutation is a significant contributor to attenuation of N13R10, likely by abrogating expression of a functional PC. IMPORTANCE Tissue culture adaptation of cytomegaloviruses rapidly selects for mutations, deletions, and rearrangements in the genome, particularly for viruses passaged in fibroblast cells. Some of these mutations are focused in the region of the genome encoding components of the pentameric complex (PC), in particular homologs of human cytomegalovirus (HCMV) proteins UL128, UL130, and UL131A. These mutations can attenuate the course of infection when the virus is reintroduced into animals for vaccine and pathogenesis studies. This study demonstrates that a deletion that arose during the process of tissue culture passage can be repaired, with subsequent restoration of pathogenicity, using BAC-based mutagenesis. Restoration of pathogenicity by repair of a frameshift mutation in GPCMV gene GP129 using this approach provides a valuable genetic platform for future studies using the guinea pig model of congenital CMV infection

Human cytomegalovirus mediates APOBEC3B relocalization early during infection through a ribonucleotide reductase-independent mechanism

Human cytomegalovirus (HCMV) infections can range from asymptomatic to severe, particularly in neonates and immunocompromised patients. HCMV has evolved strategies to overcome host-encoded antiviral defenses to achieve lytic viral DNA replication and dissemination and, under some conditions, latency and long-term persistence. Here, we show that HCMV infection causes the antiviral factor, APOBEC3B, to relocalize from the nuclear compartment to the cytoplasm. This overall strategy resembles that used by related herpesviruses. However, the HCMV relocalization mechanism utilizes a different viral factor(s) and available evidence suggests the involvement of at least one protein expressed at the early stages of infection. This knowledge is important because a greater understanding of this mechanism could lead to novel antiviral strategies that enable APOBEC3B to naturally restrict HCMV infection.The APOBEC3 family of DNA cytosine deaminases comprises an important arm of the innate antiviral defense system. The gamma-herpesviruses Epstein-Barr virus and Kaposi's sarcoma-associated herpesvirus and the alpha-herpesviruses herpes simplex virus (HSV)-1 and HSV-2 have evolved an efficient mechanism to avoid APOBEC3 restriction by directly binding to APOBEC3B and facilitating its exclusion from the nuclear compartment. The only viral protein required for APOBEC3B relocalization is the large subunit of the ribonucleotide reductase (RNR). Here, we ask whether this APOBEC3B relocalization mechanism is conserved with the beta-herpesvirus human cytomegalovirus (HCMV). Although HCMV infection causes APOBEC3B relocalization from the nucleus to the cytoplasm in multiple cell types, the viral RNR (UL45) is not required. APOBEC3B relocalization occurs rapidly following infection suggesting the involvement of an immediate early or early (IE/E) viral protein. In support of this possibility, genetic (IE1 mutant) and pharmacologic (cycloheximide) strategies that prevent the expression of IE/E viral proteins also block APOBEC3B relocalization. In comparison, the treatment of infected cells with phosphonoacetic acid, which interferes with viral late protein expression, still permits A3B relocalization. These results combine to indicate that the beta-herpesvirus HCMV uses an RNR-independent, yet phenotypically similar, molecular mechanism to antagonize APOBEC3B.

Public responses to CO2 storage sites: Lessons from five European cases

Studies of the factors involved in public perceptions of CO2 storage projects reveal a level of complexity and diversity that arguably confounds a comprehensive theoretical account. To some extent, a conceptual approach that simply organises the relevant social scientific knowledge thematically, rather than seeking an integrated explanation, is as useful as any single account that fails to do justice to the contingencies involved. This paper reviews and assembles such knowledge in terms of six themes and applies these themes to five European cases of carbon capture and storage (CCS) implementation. We identify the main factors involved in community responses to CCS as relating to: the characteristics of the project; the engagement process; risk perceptions; the actions of the stakeholders; the characteristics of the community, and the socio-political context

TWO BEST AND TWO WORST DECISIONS

My name is Kory Bierle and I am from a family ranch just east of Midland, South Dakota, on the Bad River. The name of our ranch is the Madsen Ranch. We use that name because it was my mother’s family that settled and started the place. My great-great-grandfather showed my great-grandfather where a good place for a ranch would be, and we’ve been there ever since. My house is just a few yards from where the original log house was. The gal that talked to me about participating in the Range Beef Cow Symposium this year said that, from the evaluation forms from past symposiums, you were interested in hearing from a small to average size rancher, while you got him here. We are average to even below average in size and herd numbers for Haakon County. Midland is a town of about 125 people, and I graduated from a class of 13 students. We no longer have a high school and, for a bit of trivia, the former Secretary of Agriculture for South Dakota, also a resident of Haakon County, said that Haakon County has the lowest number of women of child-bearing age in South Dakota

Computer Software Selection: Financial

Over and over we as producers are told we need to know our cost of production. As the title of my college accounting book stated, accounting is the basis for business decisions. The question comes up: how do we track these costs and make sense of all the numbers? As soon as we realize the importance of the office work and the need to get it done in a timely and efficient manner, we address how to get it done. What has been the answer for the past 20 to 25 years to help get the work done? That\u27s right, get a machine to do it (for better or worse!). Just as none of us rode the train or brought the team and buggy to this symposium, record keeping has progressed with the times with the advent of the computer, and an abundance of software programs. But remember, the computer is just another machine that helps us do our office work, much like the baler and stacker helps with the haying, it won\u27t do the work for you, just help you get it done. When considering software, remember what is said of financial reports like the balance sheet, they give you a picture of your financial position at a given time. When you take a picture, a camera is used, so think of the software that produces a balance sheet as a camera. As with cameras, which come in many models; from the simple point, shoot, and throw away to the more sophisticated studio models; software varies. As you can imagine, programs like cameras, vary in price and the degree of skill and experience needed to get the very best out of them. But have faith, the good news is that with today\u27s advances in computers and programming, even the most old fashioned cowboy or the most educated animal scientist can get a good set of financial records established. Selecting computer software is really just asking and answering a series of questions. If a lot of thought goes into what and how you want to examine your business, the selection process will be much easier. To put this in rancher (not photographer) terms, think of buying software just like buying a pickup. Before you buy a pickup you figure how you are going to use it. Will it be used primarily for going to town, or will it pull a 8x24 trailer filled with horses on mostly gravel roads, plow mud, and be used to fix fence and haul out mineral. Just like pickups, software comes in many makes and models to suit a variety of needs. And especially like modern pickups, newer programs come with many bells and whistles which you can compare to electric seats and fancy stereos
