FAPE, LRE, and Related Laws: Implications for Inclusion and Co-teaching
Unfortunately, IDEA implementation is still a problem for many schools today (Hill, Martin, & Nelson-Head, 2011). What are the causes of this? Could it be because many teachers do not have knowledge of the law? More and more students with disabilities are being served in the general education program with their peers. This is a result of several federal laws enacted to ensure that students with special needs are educated in the least restrictive environment. Inclusion of students with disabilities in the general education curriculum is a way to make sure that students are taught in the least restrictive environment with their peers. As more students with special needs are placed in the general curriculum, general education teachers must have knowledge on the legal requirements of IDEA and how to ensure legal rights of students are not violated directly or indirectly. Schools districts and teacher preparation programs have a responsibility to make certain that all teachers are aware of legal issues and laws that protect students with disabilities. One way to ensure that teachers understand the law and can implement the law is to provide teachers with specific training on legal issues in special education. This article will critically review the literature involving the evolution of special education law and the complex nature of preparing teachers for today’s classrooms. Specifically, we examine current research on best practices in inclusion, co-teaching, and teacher preparation
Identifying SARS-CoV-2 Variants of Concern through Saliva- Based RT-qPCR by Targeting Recurrent Mutation Sites
SARS-CoV-2 variants of concern (VOCs) continue to pose a public health threat which necessitates a real-time monitoring strategy to complement whole genome sequencing. Thus, we investigated the efficacy of competitive probe RT-qPCR assays for six mutation sites identified in SARS-CoV-2 VOCs and, after validating the assays with synthetic RNA, performed these assays on positive saliva samples. When compared with whole genome sequence results, the SD69-70 and ORF1aD3675-3677 assays demonstrated 93.60 and 68.00% accuracy, respectively. The SNP assays (K417T, E484K, E484Q, L452R) demonstrated 99.20, 96.40, 99.60, and 96.80% accuracies, respectively. Lastly, we screened 345 positive saliva samples from 7 to 22 December 2021 using Omicron-specific mutation assays and were able to quickly identify rapid spread of Omicron in Upstate South Carolina. Our workflow demonstrates a novel approach for low-cost, real-time population screening of VOCs

Block of NMDA receptor channels by endogenous neurosteroids: implications for the agonist induced conformational states of the channel vestibule
N-methyl-D-aspartate receptors (NMDARs) mediate synaptic plasticity, and their dysfunction is implicated in multiple brain disorders. NMDARs can be allosterically modulated by numerous compounds, including endogenous neurosteroid pregnanolone sulfate. Here, we identify the molecular basis of the use-dependent and voltage-independent inhibitory effect of neurosteroids on NMDAR responses. The site of action is located at the extracellular vestibule of the receptor's ion channel pore and is accessible after receptor activation. Mutations in the extracellular vestibule in the SYTANLAAF motif disrupt the inhibitory effect of negatively charged steroids. In contrast, positively charged steroids inhibit mutated NMDAR responses in a voltage-dependent manner. These results, in combination with molecular modeling, characterize structure details of the open configuration of the NMDAR channel. Our results provide a unique opportunity for the development of new therapeutic neurosteroid-based ligands to treat diseases associated with dysfunction of the glutamate system

Does religiosity/spirituality play a role in function, pain-related beliefs, and coping in patients with Chronic Pain? A Systematic Review
This systematic review examined the extent to which measures of religiosity/spirituality (R/S): (1) are associated with pain, function, pain-related beliefs (beliefs), coping responses, and catastrophizing in people with chronic pain; and (2) moderate the association between beliefs, coping and catastrophizing, and pain and function. Experimental and observational studies examining at least one of these research questions in adults with chronic pain were eligible. Two reviewers independently performed eligibility screening, data extraction, and quality assessment. Twenty studies were included. Most studies focused on the association between R/S and pain or function. When significant associations emerged, those between R/S and psychological function were weak to strong and positive; those between religious/spiritual well-being and pain and physical dysfunction were negative, but weak. Few studies examined the associations between R/S and beliefs/coping/catastrophizing; none examined the moderation role of R/S. The findings suggest that R/S is associated with pain and psychological function in people with chronic pain, and that viewing oneself as being "spiritual," regardless of religion, may contribute to positive psychological adjustment. More research is needed to determine the reliability of this finding. PROSPERO registry CRD42018088803.Fundação para a Ciência e Tecnologia - FCTinfo:eu-repo/semantics/publishedVersio
Impact of Isotype on the Mechanism of Action of Agonist Anti-OX40 Antibodies in Cancer: Implications for Therapeutic Combinations
BACKGROUND: OX40 has been widely studied as a target for immunotherapy with agonist antibodies taken forward into clinical trials for cancer where they are yet to show substantial efficacy. Here, we investigated potential mechanisms of action of anti-mouse (m) OX40 and anti-human (h) OX40 antibodies, including a clinically relevant monoclonal antibody (mAb) (GSK3174998) and evaluated how isotype can alter those mechanisms with the aim to develop improved antibodies for use in rational combination treatments for cancer.
METHODS: Anti-mOX40 and anti-hOX40 mAbs were evaluated in a number of in vivo models, including an OT-I adoptive transfer immunization model in hOX40 knock-in (KI) mice and syngeneic tumor models. The impact of FcγR engagement was evaluated in hOX40 KI mice deficient for Fc gamma receptors (FcγR). Additionally, combination studies using anti-mouse programmed cell death protein-1 (mPD-1) were assessed. In vitro experiments using peripheral blood mononuclear cells (PBMCs) examining possible anti-hOX40 mAb mechanisms of action were also performed.
RESULTS: Isotype variants of the clinically relevant mAb GSK3174998 showed immunomodulatory effects that differed in mechanism; mIgG1 mediated direct T-cell agonism while mIgG2a acted indirectly, likely through depletion of regulatory T cells (Tregs) via activating FcγRs. In both the OT-I and EG.7-OVA models, hIgG1 was the most effective human isotype, capable of acting both directly and through Treg depletion. The anti-hOX40 hIgG1 synergized with anti-mPD-1 to improve therapeutic outcomes in the EG.7-OVA model. Finally, in vitro assays with human peripheral blood mononuclear cells (hPBMCs), anti-hOX40 hIgG1 also showed the potential for T-cell stimulation and Treg depletion.
CONCLUSIONS: These findings underline the importance of understanding the role of isotype in the mechanism of action of therapeutic mAbs. As an hIgG1, the anti-hOX40 mAb can elicit multiple mechanisms of action that could aid or hinder therapeutic outcomes, dependent on the microenvironment. This should be considered when designing potential combinatorial partners and their FcγR requirements to achieve maximal benefit and improvement of patient outcomes
