The Role Of Microhabitats In Structuring Cave Invertebrate Communities In Guatemala, Gabrielle S.M. Pacheco, Marconi Souza Silva, Enio Cano, Rodrigo L. Ferreira

International Journal of Speleology

Several studies have tried to elucidate the main environmental features driving invertebrate community structure in cave environments. They found that many factors influence the community structure, but rarely focused on how substrate types and heterogeneity might shape these communities. Therefore, the objective of this study was to assess which substrate features and whether or not substrate heterogeneity determines the invertebrate community structure (species richness and composition) in a set of limestone caves in Guatemala. We hypothesized that the troglobitic fauna responds differently to habitat structure regarding species richness and composition than non-troglobitic fauna because they are more specialized to live …

Periodontal Regeneration Of Dehisence Defects Using A Modified Perforated Collagen Membrane. A Comparative Experimental Study, Rania Fahmy, Gehan S. Kotry, Omneya R. Ramadan

Future Dental Journal

Placement of occlusive barrier membranes in guided tissue regeneration procedures is thought to deprive the wound area from the regenerative capacity of periosteal and gingival mesenchymal stem cells. The current study was performed to determine the effect of perforated collagen membranes in enhancing periodontal tissue regeneration when compared to conventional occlusive barriers. Sixteen critical-sized dehiscence defects (4×5 mm) were surgically created in the mandibular canine teeth of eight dogs, bilaterally. Eight defects were managed by β-Tricalcium phosphate (β-TCP) alloplast and modified perforated collagen membrane, the contra lateral defects were managed by β-TCP alloplast and occlusive collagen membrane. Dogs were sacrificed …

Antibodies To Variable Domain 4 Linear Epitopes Of The Chlamydia Trachomatis Major Outer Membrane Protein Are Not Associated With Chlamydia Resolution Or Reinfection In Women, Amanda L. Collar, Alexandria C. Linville, Susan B. Core, Cosette M. Wheeler, William M. Geisler, David S. Peabody, Bryce Chackerian, Kathryn M. Frietze

Pathology Research and Scholarship

Chlamydia trachomatis is an obligate intracellular bacterium. C. trachomatis infection is the most prevalent bacterial sexually transmitted infection and can lead to pelvic inflammatory disease and infertility in women. There is no licensed vaccine for C. trachomatis prevention, in part due to gaps in our knowledge of C. trachomatis-specific immune responses elicited during human infections. Previous investigations of the antibody response to C. trachomatis have identified immunodominant antigens and antibodies that can neutralize infection in cell culture. However, epitope-specific responses to C. trachomatis are not well characterized, and the impact of these antibodies on infection outcome is unknown. We …

Innate immune signaling through the NLRP3 inflammasome is activated by multiple diabetes-related stressors, but whether targeting the inflammasome is beneficial for diabetes is still unclear. Nucleoside reverse-transcriptase inhibitors (NRTI), drugs approved to treat HIV-1 and hepatitis B infections, also block inflammasome activation. Here, we show, by analyzing five health insurance databases, that the adjusted risk of incident diabetes is 33% lower in patients with NRTI exposure among 128,861 patients with HIV-1 or hepatitis B (adjusted hazard ratio for NRTI exposure, 0.673; 95% confidence interval, 0.638 to 0.710; P < 0.0001; 95% prediction interval, 0.618 to 0.734). Meanwhile, an NRTI, lamivudine, improves insulin sensitivity and reduces inflammasome activation in diabetic and insulin resistance-induced human cells, as well as in mice fed with high-fat chow; mechanistically, inflammasome-activating short interspersed nuclear element (SINE) transcripts are elevated, whereas SINE-catabolizing DICER1 is reduced, in diabetic cells and mice. These data suggest the possibility of repurposing an approved class of drugs for prevention of diabetes.

Low Aflatoxin Levels In Aspergillus Flavus-Resistant Maize Are Correlated With Increased Corn Earworm Damage And Enhanced Seed Fumonisin, Subbaiah Chalivendra, Fangneng Huang, Mark Busman, W. Paul Williams, Jong Hyun Ham

Faculty Publications

Preharvest mycotoxin contamination of field-grown crops is influenced not only by the host genotype, but also by inoculum load, insect pressure and their confounding interactions with seasonal weather. In two different field trials, we observed a preference in the natural infestation of corn earworm (CEW; Helicoverpa zea Boddie) to specific maize (Zea mays L.) genotypes and investigated this observation. The field trials involved four maize lines with contrasting levels of resistance to Aspergillus flavus. The resistant lines had 7 to 14-fold greater infested ears than the susceptible lines. Seed aflatoxin B1 (AF) levels, in mock- and A. flavus-inoculated ears were …

The Role Of Nerves In Skeletal Development, Adaptation, And Aging., Ryan E Tomlinson, Blaine A Christiansen, Adrienne A Giannone, Damian C Genetos

Department of Orthopaedic Surgery Faculty Papers

The skeleton is well-innervated, but only recently have the functions of this complex network in bone started to become known. Although our knowledge of skeletal sensory and sympathetic innervation is incomplete, including the specific locations and subtypes of nerves in bone, we are now able to reconcile early studies utilizing denervation models with recent work dissecting the molecular signaling between bone and nerve. In total, sensory innervation functions in bone much as it does elsewhere in the body-to sense and respond to stimuli, including mechanical loading. Similarly, sympathetic nerves regulate autonomic functions related to bone, including homeostatic remodeling and vascular …

Key points

• Nrf2 is a master regulator of endogenous cellular defences, governing the expression of more than 200 cytoprotective proteins, including a panel of antioxidant enzymes.
• Nrf2 plays an important role in redox haemostasis of skeletal muscle in response to the increased generation of reactive oxygen species during contraction.
• Employing skeletal muscle-specific transgenic mouse models with unbiased-omic approaches, we uncovered new target proteins, downstream pathways and molecular networks of Nrf2 in skeletal muscle following Nrf2 or Keap1 deletion.
• Based on the findings, we proposed a two-way model to understand Nrf2 function: a tonic effect through a Keap1-independent mechanism under basal …

“Frozen Up Like An Ice Cube!”: The Influence Of Situated Learning On Pre-Service Teachers' Cultural And Linguistic Awareness, Omran Akasha

The Qualitative Report

The overall goal of this study was to explore the influence of situated learning experiences on pre-service teachers' perceptions and understandings of their future Arab students. This study investigated in part the interaction between culturally diverse families and pre-service teachers. It also explored changes in pre-service teachers’ attitudes and knowledge, their perceived applications of the situated experience to their future teaching, and the families’ reactions to this experience. Twelve Arab families volunteered to host 25 pre-service teachers as participants of this study. Results showed that the situated learning experience helped the pre-service teachers develop their cultural knowledge as well as …

Child (Un)Awareness Of Parental Incarceration As A Risk Factor: Evidence From South Korea, Youngki Woo, Melissa A. Kowalski

Criminal Justice Faculty Publications

A large body of research has been devoted to the relationship between parental incarceration and adverse outcomes for children, but such studies often compare children of incarcerated parents to those whose parents have never been imprisoned. Research is lacking regarding the effects of parental incarceration on children aware of their parent’s imprisonment compared to those who are unaware of their parent’s incarceration. In the current study we use propensity score weighting with a sample of 219 incarcerated Korean parents to examine differences in developmental outcomes between children cognizant of their parent’s incarceration and those who are unaware of parental imprisonment. …
