Comprehensive Physical Therapy Management Of Chronic Low Back Pain With Associated Remote Right Hamstring Injury: A Case Report

Low back pain (LBP) is a health condition associated with back, core, and hip muscle dysfunction as well as reduced lumbar range of motion. Core muscle stabilization, hip abductor strengthening, and lumbar range of motion are all effective techniques for treating patients with chronic LBP. Lumbar muscular imbalance can lead to hamstring injury because of change in the functional load. The purpose of this case report was to review a therapeutic exercise approach to the treatment of chronic low back pain after a remote hamstring injury, including a focus on lumbar and core stabilization, lumbar and hamstring stretching and hamstring strengthening, and a comprehensive home exercise program.https://dune.une.edu/pt_studcrposter/1159/thumbnail.jp

The Trauma Informed School: Effects on Student Success

There is a great need in schools today for school staff to be trauma informed. Many students are coming into the classroom after having dealt with traumatic experiences. Many people assume that the only trauma they are experiencing comes from abuse. However, that is not the case. Students are experiencing a variety of trauma in their lives such as death, neglect, community disasters and nation-wide disasters. All these factors change the way that children respond to others, their behaviors in the classroom and their academic success. Because of this trend, school staff are becoming trauma informed. Staff is trained to identify trauma in students and how to help the students navigate their emotions. Rather than disciplining the students for their actions, schools are working towards teaching the students how to respond and act. Trauma informed schools and staff members create a safer environment for all students and promote teaching techniques rather than discipline to support their students

SNARE VTI13 plays a unique role in endosomal trafficking pathways associated with the vacuole and is essential for cell wall organization and root hair growth in arabidopsis

Background and Aims: Root hairs are responsible for water and nutrient uptake from the soil and their growth is responsive to biotic and abiotic changes in their environment. Root hair expansion is a polarized process requiring secretory and endosomal pathways that deliver and recycle plasma membrane and cell wall material to the growing root hair tip. In this paper, the role of VTI13 (AT3G29100), a member of the VTI vesicular soluble NSF attachment receptor (SNARE) gene family in Arabidopsis thaliana, in root hair growth is described.<p></p> Methods: Genetic analysis and complementation of the vti13 root hair phenotypes of Arabidopsis thaliana were first used to assess the role of VTI13 in root hair growth. Transgenic lines expressing a green fluorescent protein (GFP)–VTI13 construct were used to characterize the intracellular localization of VTI13 in root hairs using confocal microscopy and immunotransmission electron microscopy.<p></p> Key Results: VTI13 was characterized and genetic analysis used to show that its function is required for root hair growth. Expression of a GFP–VTI13 fusion in the vti13 mutant background was shown to complement the vti13 root hair phenotype. GFP–VTI13 localized to both the vacuole membrane and a mobile endosomal compartment. The function of VTI13 was also required for the localization of SYP41 to the trans-Golgi network. Immunohistochemical analysis indicated that cell wall organization is altered in vti13 root hairs and root epidermal cells.<p></p> Conclusions: These results show that VTI13 plays a unique role in endosomal trafficking pathways associated with the vacuole within root hairs and is essential for the maintenance of cell wall organization and root hair growth in arabidopsis

Effect of the Establishment of a 2-week Brief Mindfulness Practice on Positive Nutritional Choices and Perceived Stress in College Undergraduates

College students often experience weight gain, which appears to be associated with elevated levels of stress. This stress can be due to exposure to a new environment, increased responsibility, and newfound independence that comes with living away from home. As such, identification of interventions that increase healthy eating behaviors and reduce perceived stress may promote good physical and mental health for college students. Mindfulness meditation, which is associated with lowered blood pressure, heart rate, and subjective anxiety, may be one such strategy. However, no research has examined the effect of the establishment of a mindfulness meditation practice on nutritional choices. The current study aimed to identify changes in college undergraduates’ positive nutritional choices that follow 2 weeks of mindfulness meditation paired with daily food diaries relative to participation in a nutrition-information video plus daily food diaries comparison condition. Results indicated no significant changes in mindfulness, perceived stress, or eating behaviors between groups over time, though analyses were likely hampered by low participant enrollment. Despite unexpected findings, examination of effect sizes (small to large) suggested several potentially fruitful avenues of future research

Hurricane Katrina’s Impact on Louisiana’s Educational Systems

This study examines how Hurricane Katrina affected educational statistics within Louisiana by comparing standardized test scores and school performance scores over time. To measure these educational factors, I focus on two levels of observation: district and individual. In particular, I focus on New Orleans schools before and after the hurricane and find that these educational factors increased, signaling a positive impact from Hurricane Katrina. However, on the district level there is a gap in available data due to the severity of damage to particular school systems, which led me to examine individual-level observations for more comparisons. At the individual level of observation, I focus on individuals’ test scores by categorizing the scores at particular schools and districts by the extent of damage that they received. Individuals are categorized as living in the Damage 1, Damage 2, or Damage 3 regions, where the Damage 3 region experienced the most physical damage from the natural disaster. I classified these regions based off the Federal Emergency Management Agency’s (FEMA) data on disaster declaration. As with the district-level analysis, I find that sample means for individuals’ test scores across all three damage regions increased, indicating either a time trend or a possible positive influence Hurricane Katrina had on the entire state of Louisiana. Using regression analysis with the individual-level data, I tested for possible selection biases that may have altered the scores across the damage regions. These possible selection biases include time trends, control variable effects (race, gender, limited English proficiency (LEP) status, lunch status, and education classification), group fixed effects constructed from student characteristics, and student displacement. Since these potential selection biases exist among my observations, I aimed to disentangle the true effects of the hurricane that corresponded with the initial findings of positive trends in the educational attainment measures. Without any corrections, 4th and 8th graders both saw large increased test scores after exposure to Hurricane Katrina and the natural disaster’s damages. However, after correcting for the above-mentioned biases, results show that the overall effect across all damage regions was negative, but the Damage 3 region experienced the least harm. Further regressions suggest that this is due to student evacuees’ departure from the worst damaged regions and moving elsewhere, which in turn lowers the surrounding regions’ standardized test scores. These findings show that the initial trends of largely increasing scores for New Orleans are not due to Hurricane Katrina directly, but instead, the changing composition of students is highly responsible for these trends

Using monoclonal antibodies to label living root hairs: a novel tool for studying cell wall microarchitecture and dynamics in <i>Arabidopsis</i>

Background&lt;p&gt;&lt;/p&gt; The Arabidopsis root hair represents a valuable cell model for elucidating polar expansion mechanisms in plant cells and the overall biology of roots. The deposition and development of the cell wall is central to the root hair expansion apparatus. During this process, incorporation of specific wall polymers into the growing wall architecture constitutes a critical spatio-temporal event that controls hair size and growth rate and one that is closely coordinated with the cell’s endomembrane, cytoskeletal and signal transduction apparatuses.&lt;p&gt;&lt;/p&gt; Results&lt;p&gt;&lt;/p&gt; In this study, the protocol for live cell labeling of roots with monoclonal antibodies that bind to specific wall polymers is presented. This method allows for rapid assessment of root hair cell wall composition during development and assists in describing changes to cell wall composition in transgenic mutant lines. Enzymatic “unmasking” of specific polymers prior to labeling allows for refined interpretation of cell wall chemistry. Live cell immunofluorescence data may also be correlated with transmission electron microscopy-based immunogold labeling.&lt;p&gt;&lt;/p&gt; Conclusions&lt;p&gt;&lt;/p&gt; Live Arabidopsis root hairs may be labeled with cell wall polymer-specific antibodies. This methodology allows for direct visualization of cell wall dynamics throughout development in stable transgenic plant lines. It also provides an important new tool in the elucidation of the specific interactions occurring between membrane trafficking networks, cytoskeleton and the cell wall deposition/remodeling mechanism

Structure and Statistics of the Self-Power Map

We investigate the structure of a function relevant to cryptography, given by $f: x \mapsto x^x \bmod{p}$, for $p$ a prime. We call $f$ the \textit{self-power map}. Given $x$, it is easy to calculate $f(x) \equiv x^x \pmod{p}.$ However, it is thought to be difficult to quickly calculate $f^{-1}(x^x)$. That is, given $x^x \equiv c \pmod{p}$, for a fixed $c$, it is difficult to quickly solve for $x$. We call the problem of finding the inverse of the self-power map the \textit{Self-Power Problem}. As a variation of the Discrete Logarithm Problem, the Self-Power Problem is thought to be difficult to solve and therefore considered safe for use in some versions of the ElGamal Digital Signature Algorithm. Nonetheless, utilizing functional graphs to represent the map has revealed non-random structural properties, which we describe primarily through number theory and statistics

Clathrin Heavy Chain subunits coordinate endo- and exocytic traffic and affect stomatal movement

The current model for vesicular traffic to and from the plasma membrane is accepted but the molecular requirements for this coordination are not well defined. We have identified the has1 mutant, which has a stomatal function defect, as a clathrin heavy chain 1 (CHC1) mutant allele and show that it has a decreased rate of endocytosis and growth defects that are shared with other chc1 mutant alleles. We used chc1 alleles and the related chc2 mutant as tools to investigate the effects clathrin defects have on secretion pathways and plant growth. We show that secretion and endocytosis at the plasma membrane is sensitive to CHC1 and CHC2 function in seedling roots, and that chc mutants have physiological defects in stomatal function and plant growth that have not been previously described. These findings suggest that clathrin supports specific functions of multiple cell types. Stomata movement and gas exchange is altered in chc mutants, indicating clathrin is important for stomatal regulation. The aberrant function of chc mutant stomata is consistent with the growth phenotypes observed under different water and light conditions, which are also similar to those of the secretory SNARE mutant, syp121. The syp121 and chc mutants have impaired endo- and exocytosis compared to wild type, indicating a link between SYP121-dependent secretion and clathrin-dependent endocytosis at the plasma membrane. Our findings provide evidence that clathrin and SYP121 functions are important for the coordination of endo- and exocytosis, and have an impact on stomatal function, gas exchange, and vegetative growth in Arabidopsis

Is it Too Optimistic to Assume Light Touch Interventions can Improve Educational Workers’ Wellbeing? Insights from a Field Randomized Control Trial in Canada

Educator wellbeing has broad implications for students and schools. Current approaches to address this problem are generally resource-intensive. This trial used novel nudges to increase wellbeing and decrease burnout among educators and other school-based faculty. We designed a light touch intervention where T1 received evidence-based wellbeing weekly text messages and T2 received weekly messages plus leadership endorsement emails. We evaluated this intervention in a large-scale three-arm RCT with participants (n=1,155) from K-12 schools in Manitoba, Alberta, and British Columbia. When compared to the control group, we saw no significant difference between the control group and T1 and T2 groups on burnout or wellbeing. The failure of these evidence-based text messages in increasing educators’ wellbeing and reducing their burnout highlights both the difficulty of addressing this problem and the importance of learning lessons from trials with null results to contribute to our knowledge base of improving educators’ wellbeing

University Students’ Coping Behaviours and Perceived Parental Depression: The Role of Hope and Implications for Counsellors

Research has shown links between perceived parental depressive symptomology and young adults’ depressive symptoms (Rounding & Jacobson, 2013). Hope has been linked to fewer depressive symptoms and to greater adaptive coping behaviours (Chang & DeSimone, 2001). The relation between perceived parental depression, hope, and undergraduate university students’ coping behaviours was examined. Participants were 223 undergraduates (51 males, 172 females) aged 17 to 24. Beyond perceived parental depression, hope predicted higher levels of religion/spirituality, active coping, and planning, and predicted lower levels of humour and behavioural disengagement. Implications for counselling clients at risk for intergenerational depression are discussed. La recherche a démontré qu’il existe des liens entre la symptomatologie de la dépression parentale perçue et les symptômes dépressifs chez les jeunes adultes (Rounding & Jacobson, 2013). On a établi un lien entre l’espoir et une diminution des symptômes de dépression et une amélioration des comportements adaptatifs (Chang & DeSimone, 2001). On a examiné la relation entre la dépression parentale perçue, l’espoir, et les comportements d’adaptation chez les étudiants universitaires de premier cycle. Les participants comptent 223 universitaires de premier cycle (51 hommes, 172 femmes) de 17 à 24 ans. Au-delà de la dépression parentale perçue, le facteur espoir a permis de prédire des niveaux plus élevés de religion/spiritualité, d’adaptation active, et de planification, tout en permettant de prédire des niveaux plus faibles sur le plan de l’humeur et du désengagement comportemental. On y discute des implications pour les clients en counseling à risque de la dépression intergénérationnelle
