Parenting Strategies As Predictors Of Cognitive Development Among Children, Nydia E. Martinez
Parenting Strategies As Predictors Of Cognitive Development Among Children, Nydia E. Martinez
Theses and Dissertations - UTB/UTPA
The present study investigated relationships among parenting strategies, socioeconomic status, and theory of mind development in 88 (43 girls and 45 boys) predominantly Hispanic 3 – to 7-year-old children. Vocabulary and ToM reasoning (via one true and one false belief task) levels were assessed. Parents completed demographic surveys and a disciplinary questionnaire, which presented the parents with hypothetical corrective behavioral situations. Contrary to expectations there were no significant relations between ToM, parenting strategies, and socioeconomic status in the overall sample. However, examining children tested in English and children tested in Spanish separately yielded some significant results. In the Spanish-speaking sample, …

Working memory is a highly heritable complex cognitive trait that is critical for a number of higher-level functions. However, the neural substrates of this behavioral phenotype are intricate and it is unknown through what precise biological mechanism variation in working memory is transmitted. In this review we explore different functional and structural components of the working memory circuitry, and the degree to which each of them is contributed to by genetic factors. Specifically, we consider dopaminergic function, glutamatergic function, white matter integrity and gray matter structure all of which provide potential mechanisms for the inheritance of working memory deficits. In …

Background and Aims
Obesity is increasingly a health problem and a risk factor for diabetes in young Mexican-American populations. Genetic association studies in older, mostly non-Hispanic populations have reported that polymorphisms in the candidate genes HSD11B1, CRP, ADIPOQ, PPARG, ANKK1, ABCC8 and SERPINF1 are associated with obesity or diabetes. We analyzed the polymorphisms rs846910, rs1205, rs1501299, rs1801282, rs1800497, rs757110 and rs1136287in these candidate genes, for association with obesity and metabolic traits in a young Mexican-American population from south Texas.
Methods
Genotyping of the seven common SNPs were performed by allelic discrimination assays in 448 unrelated Mexican Americans (median age = …
History Of Childhood Sexual Abuse In Mexican Origin Undergraduate Students And Its Relationship To Impulsivity, Jessica Lee Graham
History Of Childhood Sexual Abuse In Mexican Origin Undergraduate Students And Its Relationship To Impulsivity, Jessica Lee Graham
Theses and Dissertations - UTB/UTPA
It is estimated that twenty-five percent of undergraduate female students have experienced some form of sexual abuse while under the age of 18. The definition of childhood sexual abuse, CSA, consists of abusive behaviors of varying intensity and duration and varies across states. Few studies have been done addressing the relationship between CSA and impulsivity. The purpose of this study was to determine if there was an association between a history of childhood sexual abuse and impulsivity in adults of Mexican origin. One hundred fifty-one undergraduates from UTPA participated. For the purposes of this study focus was placed on the …
Binge Drinking In Undergraduate Mexican-Origin Students And Its' Relation To Impulsivity, Rosalva M. Longoria
Binge Drinking In Undergraduate Mexican-Origin Students And Its' Relation To Impulsivity, Rosalva M. Longoria
Theses and Dissertations - UTB/UTPA
Heavy drinking is more prevalent in college students ages 18 through 21 than non-students (NIAAA, 2010). Impulsivity and binge drinking have shown an association (Balodis, Potenza & Olmstead, 2009). An important aspect of this relationship is the influencing factors that may help in determining the effects of drinking on academic performance. In order to predict this behavior, we collected information on tendencies to be impulsive and those that have shown binge drinking behavior from 151 undergraduate students, 11 non-Hispanics, 3 Hispanics, and 137 Hispanics of Mexican-origin attending the University of Texas-Pan American. Of the Mexican-origin students, 37% reported binge drinking …

Health & Biomedical Sciences Faculty Publications and Presentations
The medial septum/diagonal band complex (MSDB) controls hippocampal excitability, rhythms and plastic processes. Medial septal neuronal populations display heterogeneous firing patterns. In addition, some of these populations degenerate during age-related disorders (e.g. cholinergic neurons). Thus, it is particularly important to examine the intrinsic properties of theses neurons in order to create new agents that effectively modulate hippocampal excitability and enhance memory processes. Here, we have examined the properties of voltage-gated, K+ currents in electrophysiologically-identified neurons. These neurons were taken from young rat brain slices containing the MS/DB complex. Whole-cell, patch recordings of outward currents were obtained from slow firing, fast-spiking, …

In-Group Implicit Prejudice Against Mexican Americans In The Rio Grande Valley, Christelle Fabiola Garza
Theses and Dissertations - UTB/UTPA
The existence of in-group implicit prejudice against persons of Mexican origin was examined. Implicit refers to cognitive processes that the individual is unaware. Implicit attitudes are associations between social targets and positive or negative feelings that are passively learned from the environment. The measure we used to assess implicit prejudice was the Implicit Association Test. We also examined acculturation using the Acculturation Rating Scale for Mexican Americans (Flores-Niemann et al., 1999). Family values, assessed using the Cultural Values Scale (Unger, et al., 2002), and skin tone defined by light or dark complexion using a Photovolt 577 reflectance meter, were also …

Background
To test potential differences between the actions of anti-diabetic medications, we examined the effects of oral hypoglycemic agents versus insulin glargine-apidra therapy in T2DM.
Methods
T2DM subjects were randomized to either OHA (pioglitazone, metformin, glipizide, n=9) or IT (n=12) for 6 months. Carotid intimal media thickness (CIMT), vascular reactivity [FMD] (% change in brachial arterial diameter [BD] post-ischemia), and sublingual nitrate [SLN] were measured with ultrasonography. Euglycemic hyperinsulinemic (80 mU/m2) clamp with [3]-3H-glucose and muscle biopsies were performed.
Results
FPG (∼257 to ∼124, OHA ∼256 to ∼142 mg/dl, IT) and HgbA1C (∼10.3 to ∼6.4%, OHA; ∼10.7 to ∼7.1%, IT), …

Bioactive lipids serve as intracellular and extracellular mediators in cell signaling in normal and pathological conditions. Here we describe that an important regulator of some of these lipids, the lipid phosphate phosphatase-3 (LPP3), is abundantly expressed in specific plasma membrane domains of Bergmann glia (BG), a specialized type of astrocyte with key roles in cerebellum development and physiology. Mice selectively lacking expression of LPP3/Ppap2b in the nervous system are viable and fertile but exhibit defects in postnatal cerebellum development and modifications in the cytoarchitecture and arrangement of BG with a mild non-progressive motor coordination defect. Lipid and gene profiling studies …

Elevated arterial pulse pressure and blood pressure (BP) can lead to atrophy of cerebral white matter (WM), potentially attributable to shared genetic factors. We calculated the magnitude of shared genetic variance between BP and fractional anisotropy of water diffusion, a sensitive measurement of WM integrity in a well-characterized population of Mexican Americans. The patterns of whole-brain and regional genetic overlap between BP and fractional anisotropy were interpreted in the context the pulse-wave encephalopathy theory. We also tested whether regional pattern in genetic pleiotropy is modulated by the phylogeny of WM development. BP and high-resolution (1.7 × 1.7 × 3 mm; …

Functional properties of large conductance Ca2+ activated potassium (BK) channels are determined by complex alternative splicing of the Kcnma1 gene encoding the alpha pore-forming subunit. Inclusion of the STREX exon in a C-terminal splice site is dynamically regulated and confers enhanced Ca2+ sensitivity and channel inhibition via cAMP-dependent phosphorylation. Here, we describe a real time quantitative PCR (qPCR) approach to investigate relative changes in the expression of STREX and ZERO splice variants using a newly designed set of probes and primers for TaqMan-based qPCR analysis of cDNA from the rat dentate gyrus at different time points following pilocarpine-induced status epilepticus. …

Traditionally, patients with colonic polyps not amenable to endoscopic removal require open colectomy for management. We evaluated our experience with minimally invasive approaches including endoscopic mucosal resection (EMR), laparoscopicassisted endoscopic polypectomy (LAEP), and laparoscopic-assisted colectomy (LAC). Patients referred for surgery for colonic polyps were selected for one of three minimally invasive modalities. A total of 123 patients were referred for resection of “difficult” polyps. Thirty underwent EMR, 25 underwent LAEP, and 68 underwent LAC. Of those selected to undergo EMR or LAEP, 76.4% were successfully managed without colon resection. The remaining 23.6% underwent LAC. Nine complications were encountered, including two …
