BACKGROUND: The concentration- and time-response relationships of lipid emulsion (LE; Intralipid) on the recovery of myocardial contractility following bupivacaine (BPV)-induced asystole are poorly defined. METHODS: After achieving asystole by 500-μM BPV, varied concentrations of LE were applied to determine the recovery of stimulated contractile responses and contractions in the cardiac tissues of guinea pigs at a 1.2-Hz stimulation rate. These experiments were performed with LE in either a recirculating (2%-16%) or washout (nonrecirculating) condition (0...

Rare and private variants of uncertain significance (VUS) are routinely identified in clinical panel, exome, and genome sequencing. We investigated the power of single family co-segregation analysis to aid classification of VUS. We simulated thousands of pedigrees using demographics in China and the United States, segregating benign and pathogenic variants. Genotypes and phenotypes were simulated using penetrance models for Lynch syndrome and breast/ovarian cancer. We calculated LOD scores adjusted for proband ascertainment (LODadj), to determine power to yield quantitative evidence for, or against, pathogenicity of the VUS...

Th1 and Th17 cells have an established role in protective immunity to Bordetella pertussis, but this evidence is based largely on peripheral T cells. There is emerging evidence that local tissue-resident memory T (TRM) cells that accumulate in tissue following mucosal infection may be crucial for long-term immunity. In this study, we examined the role of respiratory CD4 TRM cells in immunity to B. pertussis Natural immunity to B. pertussis induced by infection is considered long lasting and effective at preventing reinfection...

BACKGROUND: There is a need for objective movement assessment for clinical research trials aimed at improving gait and balance in persons with multiple sclerosis (PwMS). Wireless inertial sensors can accurately measure numerous walking and balance parameters but these measures require evaluation of reliability in PwMS. The current study determined the test-retest reliability of wireless inertial sensor measures obtained during an instrumented standing balance test and an instrumented Timed Up and Go test in PwMS...

Lynch syndrome (LS) is a hereditary cancer predisposition caused by inactivating mutations in DNA mismatch repair (MMR) genes. Mutations in the MSH6 DNA MMR gene account for approximately 18% of LS cases. Many LS-associated sequence variants are nonsense and frameshift mutations that clearly abrogate MMR activity. However, missense mutations whose functional implications are unclear are also frequently seen in suspected-LS patients. To conclusively diagnose LS and enroll patients in appropriate surveillance programs to reduce morbidity as well as mortality, the functional consequences of these variants of uncertain clinical significance (VUS) must be defined...

Postsynaptic glycine receptor (GlyR) chloride channels mediate inhibitory neurotransmission in the spinal cord and brain stem, although presynaptic and extrasynaptic GlyRs are expressed more widely throughout the brain. In humans, GlyRs are assembled as homo- or heteromeric pentamers of α1-3 and β subunits. GlyR malfunctions have been linked to a range of neurological disorders including hyperekplexia, temporal lobe epilepsy, autism, breathing disorders, and chronic inflammatory pain. Although it is possible that GlyRs may eventually be clinically targeted for a variety of neurological disorders, most research to date has focused on developing GlyR-targeted treatments for chronic pain...

Lynch Syndrome (LS) is the most common dominantly inherited colorectal cancer (CRC) predisposition and is caused by a heterozygous germline defect in one of the DNA mismatch repair (MMR) genes MLH1, MSH2, MSH6, or PMS2. High microsatellite instability (MSI-H) and loss of MMR protein expression in tumours reflecting a defective MMR are indicators for LS, as well as a positive family history of early onset CRC. MSH2 and MSH6 form a major functional heterodimer, and MSH3 is an alternative binding partner for MSH2...

This project examines the Northeast Iowa Food and Fitness Initiative, a policy-, community-, and school-based effort to slow children's body mass index (BMI) growth over 6 years. Kindergarteners (K) to fifth graders (5) from 10 different school districts participated (N = 4101). Students with 0 to 1 years of initiative exposure showed greater growth in BMI compared with children who had 2 to 6 years of exposure, resulting in K-5 BMI savings of 1.5 points (6 lb) for median-height boys and girls. Results suggest that changes to policies, communities, and schools may provide effective obesity reduction in children...

Alcohol drinking and, to a lesser extent, cigarette smoking are risk factors for a first primary breast cancer. Information on these behaviours at diagnosis may contribute to risk prediction of contralateral breast cancer (CBC) and they are potentially modifiable. The WECARE Study is a large population-based case-control study of women with breast cancer where cases (N=1521) had asynchronous CBC and controls (N=2212), matched on survival time and other factors, had unilateral breast cancer (UBC). Using multivariable conditional logistic regression to estimate rate ratios (RR) and 95% confidence intervals (CI), we examined the risk of CBC in relation to drinking and smoking history at and following first diagnosis...

We present a case of an endometrial cancer patient with germline mutation in MutS homolog 6 (MSH6), associated with Lynch syndrome. A 60-year-old Korean woman had a personal history of colon cancer 23 years ago. She also had a family history of endometrial cancer and colon cancer of her sisters and brothers. Immunohistochemistry was negative for MutL homolog 1 (MLH1) and positive for MutS homolog 2 (MSH2). Based on these findings, she underwent genetic counseling and testing that revealed a frameshift germline mutation at MSH6 (c...

Purpose: Determination of microsatellite instability (MSI) by PCR is the gold standard; however, immunohistochemistry (IHC) of mismatch repair (MMR) proteins is frequently performed instead. The reliability of these methods on post-neoadjuvant-therapy specimens is unknown.  We examined the effect of neoadjuvant therapy on MSI results by PCR and IHC. Experimental design: A total of 239 colorectal cancers resected after neoadjuvant therapy were assessed for MSI with PCR and IHC. PCR and IHC results for matched paired pre- and post-treatment specimens were compared...

Endocannabinoids (ECBs) depress transmitter release at sites throughout the brain. Here, we describe another form of ECB signaling that triggers a novel form of long-term potentiation (LTP) localized to the lateral perforant path (LPP) which conveys semantic information from cortex to hippocampus. Two cannabinoid CB1 receptor (CB1R) signaling cascades were identified in hippocampus. The first is pregnenolone sensitive, targets vesicular protein Munc18-1 and depresses transmitter release; this cascade is engaged by CB1Rs in Schaffer-Commissural afferents to CA1 but not in the LPP, and it does not contribute to LTP...
