Laying Out an Unwelcome Mat to Public Beach Access

Florida beaches attract tourists from around the world. However, many are unaware of the issues surrounding public beach access; issues that potentially threaten the ability of the Florida visitor to enjoy the warm sands and blue waters that define the state to many. In her comment, Ms. Sullivan revisits the issue of public beach access and the doctrine of customary usage. Specifically, the battle that is occurring in the over-development of Florida Panhandle beaches is analyzed, with the fishing village of Destin serving as a prime example. The effect of recent Florida decisions concerning strict adherence to local comprehensive plans is applied to the current problems facing Panhandle beaches. Finally, Ms. Sullivan documents four distinct areas that have historically proved problematic within other areas of the state and discusses potential remedies as applied to the village of Destin

Using a Cured Meat Model System to Investigate Factors that Influence Cured Color Development

Producing cured meats manufactured with natural ingredients could impact cured meat characteristics, including color. The objective of this study was to determine the effects of nitrite source (sodium nitrite or cultured celery juice powder), reducing agents (no reducing compound or sodium erythorbate/ ascorbic acid), and holding times prior to cooking on cured color development in a meat model system. The addition of reducing compounds had the largest impact on cured color development and reduced residual nitrite in a cured meat model system. Treatments cured with sodium nitrite had slightly greater cured color development than treatments cured with celery juice powder. Holding times prior to cooking had limited impact on cured color development. These findings indicate that processors can produce cured meats with adequate cured meat color using celery juice powder and ascorbic acid from cherry powder without needing to extend holding time prior to cooking

Systematic assessment of HER2/neu in gynecologic neoplasms, an institutional experience.

BackgroundHER2/neu overexpression and/or amplification has been widely studied in a number of solid tumors, primarily in the breast. In gynecologic neoplasms, determination of HER2/neu status has not been well studied as a predictive biomarker in anti-HER2/neu treatment.MethodsWe systematically evaluated the HER2/neu reactions by immunohistochemistry and fluorescent in situ hybridization in malignant gynecologic neoplasms as experienced in our institution.ResultsThe HER2/neu overexpression or amplification occurred in 8 % of the cancers of the gynecological organs in our series. Majority of the HER2/neu overexpression and/or amplification occurred in clear cell (27 %) and serous (11 %) carcinomas. HER2/neu positivity was also seen in undifferentiated as well as in mixed clear cell and serous carcinomas. Discordant IHC and FISH results (positive by FISH but not IHC) was seen in 2 cases. Majority of the HER2/neu overexpression and/or amplification occurs in the endometrium rather than the ovary. Heterogeneity of the HER2/neu by IHC staining was in < 2 % of the tumors in our series.ConclusionsWe recommend the HER2/neu studies on Müllerian carcinomas of clear cell, serous, and undifferentiated types, particularly when they arise in the endometrium. Since there are some discordant IHC/FISH results, we also propose performing the HER2/neu testing by FISH when the IHC score is less than 3 + 

Induction of Hemeoxygenase-1 Reduces Renal Oxidative Stress and Inflammation in Diabetic Spontaneously Hypertensive Rats

The renoprotective mechanisms of hemeoxygenase-1 (HO-1) in diabetic nephropathy remain to be investigated. We hypothesize that HO-1 protects the kidney from diabetic insult via lowering renal oxidative stress and inflammation. We used control and diabetic SHR with or without HO-1 inducer cobalt protoporphyrin (CoPP) treatment for 6 weeks. Urinary albumin excretion levels were significantly elevated in diabetic SHR compared to control and CoPP significantly attenuated albumin excretion. Immuno-histochemical analysis revealed an elevation in TGF-β staining together with increased urinary collagen excretion in diabetic versus control SHR, both of which were reduced with CoPP treatment. Renal oxidative stress markers were greater in diabetic SHR and reduced with CoPP treatment. The increase in renal oxidative stress was associated with an elevation in renal inflammation in diabetic SHR. CoPP treatment also significantly attenuated the markers of renal inflammation in diabetic SHR. In vitro inhibition of HO with stannous mesoporphyrin (SnMP) increased glomerular NADPH oxidase activity and inflammation and blocked the anti-oxidant and anti-inflammatory effects of CoPP. These data suggest that the reduction of renal injury in diabetic SHR upon induction of HO-1 are associated with decreased renal oxidative stress and inflammation, implicating the role of HO-1 induction as a future treatment of diabetic nephropathy

The Effect of Viewing Appearance-Based and Self-Compassion Social Media Content on Body Image

The present study investigated the impact of viewing appearance-focused body-positive content versus non-appearance focused self-compassion content on a person’s self-image. Previous studies have demonstrated that viewing body-positive content improves body self-esteem. Additionally, self-compassion content may be a protective factor against body dissatisfaction. Although body-positive content is associated with increased body self-esteem, some question remains whether the continued focus on appearance is an effective strategy. Therefore, the purpose of the current study is to examine whether non-appearance based content provides benefits above and beyond those provided by body positivity. It was hypothesized that those who viewed non-appearance based content would report greater positive effects on body self-esteem than those who view appearance focused content, as non-appearance focused content directs the viewer\u27s attention away from self-objectifying tendencies. Covariation effects of ideal internalization and trait appearance comparison characteristics were also investigated. Both experimental conditions demonstrated a significant increase in measures of body self-esteem, however they did not differ significantly from each other. Ideal internalization was found to be a significant covariate. Exploratory gender analyses indicated that while both types of positive content significantly increased body self-esteem in both men and women, appearance-neutral content may have a stronger effect for men. Results of this study provide further evidence for the effectiveness of including both appearance-based and appearance-neutral content in social media interventions for increasing positive body image. Additionally results suggest that gender differences should be continued to be investigated in future research as varying the type of content may enhance effectivity by gender

Differential regulation of bladder pain and voiding function by sensory afferent populations revealed by selective optogenetic activation

Bladder-innervating primary sensory neurons mediate reflex-driven bladder function under normal conditions, and contribute to debilitating bladder pain and/or overactivity in pathological states. The goal of this study was to examine the respective roles of defined subtypes of afferent neurons in bladder sensation and function in vivo via direct optogenetic activation. To accomplish this goal, we generated transgenic lines that express a Channelrhodopsin-2-eYFP fusion protein (ChR2-eYFP) in two distinct populations of sensory neurons: TRPV1-lineage neurons (Trpv1Cre;Ai32, the majority of nociceptors) and Nav1.8+ neurons (Scn10aCre;Ai32, nociceptors and some mechanosensitive fibers). In spinal cord, eYFP+ fibers in Trpv1Cre;Ai32 mice were observed predominantly in dorsal horn (DH) laminae I-II, while in Scn10aCre;Ai32 mice they extended throughout the DH, including a dense projection to lamina X. Fiber density correlated with number of retrogradely-labeled eYFP+ dorsal root ganglion neurons (82.2% Scn10aCre;Ai32 vs. 62% Trpv1Cre;Ai32) and degree of DH excitatory synaptic transmission. Photostimulation of peripheral afferent terminals significantly increased visceromotor responses to noxious bladder distension (30–50 mmHg) in both transgenic lines, and to non-noxious distension (20 mmHg) in Scn10aCre;Ai32 mice. Depolarization of ChR2+ afferents in Scn10aCre;Ai32 mice produced low- and high-amplitude bladder contractions respectively in 53% and 27% of stimulation trials, and frequency of high-amplitude contractions increased to 60% after engagement of low threshold (LT) mechanoreceptors by bladder filling. In Trpv1Cre;Ai32 mice, low-amplitude contractions occurred in 27% of trials before bladder filling, which was pre-requisite for light-evoked high-amplitude contractions (observed in 53.3% of trials). Potential explanations for these observations include physiological differences in the thresholds of stimulated fibers and their connectivity to spinal circuits

Serum Monocyte Chemoattractant Protein-1 in Pancreatic Cancer

Background/Aims. Pancreatic ductal adenocarcinoma (PDA) has etiological association with chronic inflammation. Elevated circulating levels of inflammatory mediators, such as monocyte chemoattractant protein-1 (MCP-1), are found in obese individuals. We hypothesized that serum MCP-1 levels are elevated in obese PDA patients. Methods. ELISA was used to analyze MCP-1 serum levels in PDA (n = 62) and intraductal papillary mucinous neoplasms (IPMN) (n = 27). Recursive partitioning statistical analysis investigated the relationship between log MCP-1 and clinicopathological parameters. Results. Log MCP-1 values were significantly (P < 0.05) elevated in patients with BMI ≥ 37.5. In patients with BMI < 37.5, average log MCP-1 values were significantly elevated in PDA patients when compared to IPMN patients. Within the IPMN group, higher log MCP-1 levels correlated with increased age. Recursive partitioning analysis of IPMN versus PDA revealed a strategy of predicting characteristics of patients who are more likely to have cancer. This strategy utilizes log MCP-1 as the primary factor and also utilizes smoking status, gender, and age. Conclusion. MCP-1 is a promising biomarker in pancreatic cancer. The potential of using MCP-1 to distinguish PDA from IPMN patients must be studied in larger populations to validate and demonstrate its eventual clinical utility

“Anything that benefits the workers should benefit the client”: Opportunities and Constraints in Self-Directed Care during the COVID-19 Pandemic

Reuse is restricted to non-commercial and no derivative uses.Self-directed care (SDC) models allow Home and Community Based Services (HCBS) consumers to direct their own care, thus supporting flexible, person-centered care. There are many benefits to the SDC model but access to resources is essential to successful outcomes. Considering the autonomy and flexibility associated with SDC, it is important to understand how SDC responded to the COVID-19 pandemic and the resources available to help manage this situation. We conducted 54 in-depth interviews with HCBS consumers, direct support workers, family caregivers, and providers to examine the impact of COVID-19 on HCBS services in Kansas. Findings illuminate how self-directed consumers carried a lot of employer responsibility, with limited resources and systemic barriers constraining self-determination and contributing to unmet care needs, stress, and burden. Policy flexibilities expanding the hiring of family members were beneficial but insufficient to address under-resourced working conditions and labor shortages that were exacerbated by the pandemic
