Abstract
The rationale for CIM treatments in youth psychoses is to optimize treatment by targeting symptoms not resolved by antipsychotics, such as negative symptoms (major drivers of disability). Adjunctive omega-3 fatty acids (ω-3 FA) or N-acetyl cystine (NAC usage for > 24-week) can potentially reduce negative symptoms and improve function. ω-3 FA or exercise may prevent progression to psychosis in youth (in prodromal stage). Weekly 90-minute moderate to vigorous physical activity or aerobic exercise can reduce positive and negative symptoms. Awaiting better research, CIM agents are also recommended because they are devoid of any serious side-effects.

Abstract
INTRODUCTION Schwannomas are benign neurogenic tumors that make up less than 1 percent of all gastrointestinal tumors. Schwannoma can occur along peripheral nerves anywhere throughout the body. Gastrointestinal schwannoma is relatively rare and most commonly occurs in the stomach, small intestine, and colon, respectively. There have only been a handful of case reports describing appendiceal schwannomas. Approximately 30-50 percent of appendicular tumors show clinical symptoms and signs similar to those of appendicitis. CASE REPORT A 36-year-old male presented initially for right lower quadrant pain of one day duration. He denied any other associated symptoms. CT imaging of abdomen and pelvis showed a fluid-filled and dilated appendix with fat stranding consistent with appendicitis. He underwent laparoscopic appendectomy without complication. The pathology report showed a well-defined proliferation of bland uniform cells that contained small smooth nuclei and abundant foamy cytoplasm at the tip of the appendix. Scattered eosinophils were noted. These neoplastic cells were positive for S100 and negative for CD68, CD34, and CD117, most consistent with a schwannoma. DISCUSSION Diagnosing appendiceal schwannoma pre-operatively is a challenging task due to the rare nature of the tumors and the lack of clinical features to separate it from other appendiceal pathology. Appendiceal schwannomas are benign but it is unclear if malignant transformation is possible if left untreated. While there are currently no agreed upon treatment guidelines for appendiceal schwannoma, it is currently thought that complete surgical resection is the best treatment while chemotherapy and radiotherapy are not effective.

Abstract
Background The Center for Disease Control provides recommendations for preventative services and screenings including recommendations for a one-time HIV screening of all adult patients between the ages of 13-64. But not all clinics are fully compliant with these recommendations. We identified a need for increased screening at two clinics in a rural setting. As a healthcare quality improvement initiative, we developed educational informatics to increase screening compliance. Methods This project assessed HIV screening rates before and after educational interventions at two clinics, the Coyote Clinic and the Avera Downtown Clinic. Three changes were implemented to increase the HIV screening rate and ultimately provide more effective high-quality health care. The three initiatives focused on patients, physicians, and student volunteers in order to provide a strong foundation of knowledge to all parties involved in a patient's care. Results Prior to any interventions, the baseline screening rate (screenings/100 persons) at the Avera Downtown Clinic was 0.84 while the screening rate at the Coyote Clinic was 0.00. After the proposed interventions, the screening rate of the Downtown Clinic improved to 3.97 and the screening rate at the Coyote Clinic improved to 29.4. Using a Fisher's Exact test, we found a statistically significant post-intervention increase in HIV screening at the Coyote Clinic after the intervention (p = 0.0002) but not at the Downtown Clinic (p = 0.0940.) Conclusion HIV screening rates improved after the implementation of interventional education initiatives tailored for patients, medical students, and physicians. Implementation of low-cost quality improvement measures such as the ones detailed herein may significantly improve long-term patient management, particularly in the context of screening tests.

Abstract
Chemically synthesized small interfering RNAs (siRNAs) are tools used for silencing the expression of a single gene. They are mainly employed in basic research applications, but may also have great potential in therapeutic applications. Longer double-stranded RNAs, such as Dicer-substrate 27mers, trigger gene silencing through the intrinsic RNAi pathway. The design of these Dicer-substrate 27mers has been optimized so they can be oriented by Dicer to consistently select the antisense (guide) strand after cleavage to shorter siRNAs, leading to predictable mRNA cleavage. In this paper we describe evidence that these Dicer-substrate 27mers produce more potent and sustained gene silencing for four genes when compared with synthetic 21mers that have the same guide-strand sequence. Furthermore, improved silencing by these 27mers is often more pronounced at lower concentrations.

Abstract
BACKGROUND Workers in hydroelectric plants appear to be readily sensitized to caddisfly allergens. This sensitization probably occurs de novo from occupational exposure. In some workers, sensitization occurs on a non-atopic background. Cytokine synthesis of IFN-gamma, IL-5 and IL-13 in atopic and non-atopic caddisfly-allergic workers was examined to determine if responses were similar or different. METHODS Peripheral blood mononuclear cells were isolated from atopic caddisfly-allergic workers, non-atopic caddisfly-allergic workers and non-atopic caddisfly-exposed but non-allergic workers. Stimulation with caddisfly antigens was carried out and synthesis of IFN-gamma, IL-5 and IL-13 was determined by sandwich ELISA. RESULTS Both caddisfly-allergic and non-allergic subjects responded to stimulation with caddisfly extract. The response in non-atopic caddisfly-non-allergic subjects was TH1 predominant, while that in atopic caddisfly-allergic subjects was TH2 predominant. The response in non-atopic caddisfly-allergic subjects was between that of the atopic caddisfly-allergic workers and the non-atopic caddisfly-non-allergic workers and the trend was to a TH2 response. Work-related symptoms were similarly intermediate between the atopic caddisfly-allergic and non-atopic caddisfly-non-allergic group. Differences were significant for IFN-gamma/IL-5 ratios but not IFN-gamma/IL-13 ratios for atopic and non-atopic caddisfly-allergic individuals, compared to non-atopic caddisfly-non-allergic workers. However, a linear relationship existed between IFN-gamma synthesis and IL-5 and IL-13 synthesis in non-atopic caddisfly-allergic workers but not in atopic caddisfly-allergic subjects. CONCLUSIONS Caddisfly allergy in hydroelectric workers may be a useful model for the development of allergy to a previously unencountered allergen, and points to some interesting differences between atopic and non-atopic subjects who become sensitized to environmental allergens.

Abstract
DsrA is an 85-nucleotide, untranslated RNA that has multiple regulatory activities at 30 degrees C. These activities include the translational regulation of RpoS and H-NS, global transcriptional regulators in Escherichia coli. Hfq is an E. coli protein necessary for the in vitro and in vivo replication of the RNA phage Qbeta. Hfq also plays a role in the degradation of numerous RNA transcripts. Here we show that an hfq mutant strain is defective for DsrA-mediated regulation of both rpoS and hns. The defect in rpoS expression can be partially overcome by overexpression of DsrA. Hfq does not regulate the transcription of DsrA, and DsrA does not alter the accumulation of Hfq. However, in an hfq mutant, chromosome-expressed DsrA was unstable (half-life of 1 min) and truncated at the 3' end. When expressed from a multicopy plasmid, DsrA was stable in both wild-type and hfq mutant strains, but it had only partial activity in the hfq mutant strain. Purified Hfq binds DsrA in vitro. These results suggest that Hfq acts as a protein cofactor for the regulatory activities of DsrA by either altering the structure of DsrA or forming an active RNA-protein complex.

Abstract
Transforming growth factor beta s (TGF-beta s) are 25-kD multifunctional proteins that regulate inflammation and connective tissue synthesis. With rare exception TGF-beta 1 is secreted noncovalently bound to a latency-associated peptide (LAP) that renders the mature TGF-beta 1 biologically inactive. An important mechanism for the control of TGF-beta 1 action is the regulation of the post-translational processing that removes the LAP from the mature peptide and renders it biologically active. In a model of pulmonary inflammation and fibrosis induced by the antineoplastic antibiotic, bleomycin, we have demonstrated that explanted alveolar macrophages secrete progressively increasing quantities of a biologically active form of TGF-beta 1, the secretion of which was maximal 7 days after bleomycin administration. Thereafter, there was a rapid decline in the secretion of the active form of TGF-beta 1, whereas the latent form continued to be secreted in elevated quantities. Plasmin, a serine protease, was transiently generated by the same bleomycin-activated alveolar macrophages and paralleled the rise in active TGF-beta 1. When alpha 2-antiplasmin, an inhibitor of plasmin, was added to cultures of alveolar macrophages, the post-translational activation of L-TGF-beta 1, was totally abrogated. When plasmin was added to alveolar macrophages in culture, there was complete activation of the L-TGF-beta 1 that had been secreted during the culture period. However, there was no effect of plasmin on the same alveolar macrophage-derived L-TGF-beta 1 in cell-free conditioned media. Our findings suggest that the secretion of an active form of TGF-beta 1 by alveolar macrophages is regulated by the generation of plasmin and requires that the alveolar macrophages be present. Because the diminution of active TGF-beta 1 coincides with the resolution of inflammation, this suggests that the availability of plasmin regulates the biologically active form of TGF-beta 1, and thus, the inflammation seen after bleomycin-induced lung injury.

Abstract
The distribution of androgen receptor-like (AR) immunoreactivity was mapped in brains of (a) intact, sham-castrated and (b) castrated male hamsters. The pattern of AR-immunoreactive (AR-ir) staining was, in general, similar to that reported for gonadal steroid autoradiography of the male hamster brain. Moreover, with one exception, AR-like staining was similar in intact and castrated males, and occurred in the medial preoptic area, bed nucleus of stria terminalis, amygdala, hippocampus, thalamus, and several hypothalamic nuclei including the periventricular, supraoptic, and ventromedial nuclei, and median eminence. However, while AR-ir labeling was virtually absent in the lateral septum of intact males, it was clearly present in the lateral septum of castrated males. The view that androgen receptors in brain generally decline after castration received no support from this study.

Abstract
In a model of pulmonary inflammation and fibrosis induced by the antineoplastic antibiotic, bleomycin, we previously demonstrated that TGF-beta was markedly elevated within 7 d of bleomycin administration. At the time of maximal TGF-beta production, TGF-beta 1 was localized by immunohistochemistry to be present almost exclusively in alveolar macrophages. In this study, we have demonstrated that alveolar macrophages stimulated by bleomycin-induced injury secrete large quantities of biologically active TGF-beta 1 when explanted into tissue culture. However, alveolar macrophages from normal saline-treated rats secrete small quantities of biologically inactive TGF-beta. In contrast, splenic macrophages secrete large quantities of inactive TGF-beta and are unaffected by the intratracheal bleomycin treatment. High doses of the corticosteroid methylprednisolone given intramuscularly before and concomitantly with bleomycin administration prevented the influx of alveolar macrophages into the lungs, diminishing both the number of macrophages present in the alveoli and the total lung content of TGF-beta. However, the rate of secretion of TGF-beta by alveolar macrophages recovered from the alveoli was unchanged after corticosteroid treatment. When activated alveolar macrophages were cultured in the presence of several concentrations of dexamethasone that completely suppressed IL-1 secretion, little effect on TGF-beta secretion was observed. The findings in this study demonstrate that during bleomycin-induced injury, alveolar macrophages not only secrete large quantities of active TGF-beta 1, but are a predominant source of the enhanced TGF-beta response seen in this model. Furthermore, the alveolar macrophage secretion of TGF-beta is not inhibited by the presence of high concentrations of corticosteroids.

Abstract
Arthroscopic evaluation of patients with an acute anterior shoulder dislocation was done to identify and classify the intraarticular lesions that might predict recurrent dislocations. Forty-five shoulders fit the following criteria for inclusion in our study: initial dislocation with no prior history of shoulder problems; confirmation of the dislocation radiographically or reduction by a physician; and arthroscopy within 10 days. The 42 men and 3 women had an average age of 21.2 years (range, 14 to 28 years). Mechanism of injury was a twisting of the arm into forced abduction and external rotation, a fall on the outstretched arm, or a direct blow to the shoulder. Based on this preliminary study of 45 shoulders, we present a classification of the lesions found in the acute shoulder dislocation. Group 1 (six shoulders) had capsular tears with no labral lesions: these shoulders were stable under anesthesia and had no or minimal hemarthrosis. Group 2 (11 shoulders) had capsular tears and partial labral detachments: these shoulders were mildly unstable and had mild to moderate hemarthrosis. Group 3 (28 shoulders) had capsular tears with labral detachments: these shoulders were grossly unstable and had large hemarthrosis. They had complete capsular/labral detachments. In the past, redislocation rates have been primarily related to age at the time of initial dislocation and, to a lesser degree, the period of immobilization. We have identified the intraarticular lesions in 45 patients with an initial anterior glenohumeral dislocation and classified these shoulders into three groups based on the lesions found. By doing so, we can develop a more accurate method of determining which shoulders are prone to recurrent dislocation.(ABSTRACT TRUNCATED AT 250 WORDS)
