Abstract
The purpose of this quasi-experimental study was to evaluate the effects of two farm-to-school programs, specifically the Field-to-Fork Multi-visit Program (N = 264) and the Field-to-Fork After-school Club (N = 56), on nutritional outcomes of elementary school students (third to fifth grade) from urban, diverse, and lower-income communities. Data were collected via self-report surveys measuring: (a) knowledge of recommendations for daily fruit and vegetable intake; (b) fruit and vegetable consumption; (c) knowledge of cooking a healthy recipe using vegetables; and (d) desire for farm fresh foods at school. Statistical analyses included McNemar's and Wilcoxon signed rank tests. The proportion of students knowing how to cook a vegetable rich recipe increased with both programs (Multi-visit Program p < .001; After-school Club p = .002). Vegetable consumption increased with the After-school Club (p = .002). Farm-to-school programming can increase knowledge of cooking vegetable rich recipes and vegetable intake among elementary school students from diverse, urban, and lower-income communities.

Abstract
Objective To illustrate Black youth's perceptions of police violence in West Louisville, Kentucky, how they make sense of it, and their responses to it. Method The study used qualitative interviews with youth ages 10 to 24 residing in West Louisville. The interviews did not specifically inquire about experiences with police, but the theme emerged so strongly from the overall analysis that the current study was warranted. The research team employed a constructivist analytic approach. Results The analysis yielded two overarching themes, each with several subthemes. The first theme was Black youth experience profiling and harassment by police, with subthemes focused on youth feeling targeted, youth recognizing policing as a tactic to remove them from their community, and youth being acutely aware of police-involved violence. The second theme was Black youth's experiences with the police cultivates mistrust and unsafety, with subthemes including police seen as more likely to harm than help, police not resolving injustices against Black people, and police presence escalating conflict in Black communities. Conclusions Youth's narratives regarding their experiences with police highlight the physical and psychological violence enacted by police who come into their community, supported by the law enforcement and criminal justice systems. Youth recognize systemic racism in these systems and how it affects officers' perceptions of them. The long-term implications of persistent structural violence these youth endure has implications on their physical and mental health and wellbeing. Solutions must focus on transforming structures and systems.

Abstract
Youth voice has become a very popular term in youth development research and practice. However, there is a lack of critical dialogue surrounding the role of youth in the peer-review research process. This article explores the intersections of youth voice, marginalization in the peer-review research process, and the importance of utilizing a social justice youth development framework when reading the youth essays selected for this special issue.

Abstract
TCF4 is involved in neurodevelopment, and intergenic and intronic variants in or close to the TCF4 gene have been associated with susceptibility to schizophrenia. However, the functional role of TCF4 at the level of gene expression and relationship to severity of core psychotic phenotypes are not known. TCF4 mRNA expression level in peripheral blood was determined in a large sample of patients with psychosis spectrum disorders (n = 596) and healthy controls (n = 385). The previously identified TCF4 risk variants (rs12966547 (G), rs9960767 (C), rs4309482 (A), rs2958182 (T) and rs17512836 (C)) were tested for association with characteristic psychosis phenotypes, including neurocognitive traits, psychotic symptoms and structural magnetic resonance imaging brain morphometric measures, using a linear regression model. Further, we explored the association of additional 59 single nucleotide polymorphisms (SNPs) covering the TCF4 gene to these phenotypes. The rs12966547 and rs4309482 risk variants were associated with poorer verbal fluency in the total sample. There were significant associations of other TCF4 SNPs with negative symptoms, verbal learning, executive functioning and age at onset in psychotic patients and brain abnormalities in total sample. The TCF4 mRNA expression level was significantly increased in psychosis patients compared with controls and positively correlated with positive- and negative-symptom levels. The increase in TCF4 mRNA expression level in psychosis patients and the association of TCF4 SNPs with core psychotic phenotypes across clinical, cognitive and brain morphological domains support that common TCF4 variants are involved in psychosis pathology, probably related to abnormal neurodevelopment.

Abstract
Review of splenectomies carried out for haematological disease over a ten-year period, at a district hospital, shows that the indications for splenectomy have changed substantially over this time. Fewer patients with idiopathic thrombocytopenic purpura now require splenectomy, however its role in the management of lymphoproliferative disorders has expanded. Splenectomy remains an important therapeutic option for a range of haematological disorders: this series shows it to be a safe and effective operation in selected patients, although it is not without both short and long-term sequelae.

Abstract
BACKGROUND The aim of a circumcision is to remove sufficient foreskin from the penile shaft and preputial epithelium to uncover the glans. Removal of too much preputial skin may lead to an unsatisfactory cosmetic and functional result. Patients with a congenital anomaly known as 'buried penis' are particularly susceptible to this. In this condition, abnormal dartos fascial bands or muscle fibres tether the penile shaft and as a result conceal its true length. CASE REPORT A 5-year-old boy underwent circumcision but his 'buried penis' was not recognised by the surgeon pre-operatively. Unfortunately, his penile shaft was left almost entirely denuded of skin as a result. The wound required a full thickness graft. Follow-up at 1 year has so far been satisfactory. CONCLUSIONS This case highlights the importance of early recognition of a buried penis when considering circumcision. It demonstrates the abnormal anatomy of a buried penis and its management. It also provides a potential reconstructive option in cases of excess skin removal.

Abstract
Delayed rejection of pig kidney xenografts by primates is associated with vascular injury that may be accompanied by a form of consumptive coagulopathy in recipients. Using a life-supporting pig-to-baboon renal xenotransplantation model, we have tested the hypothesis that treatment with recombinant human antithrombin III would prevent or at least delay the onset of rejection and coagulopathy. Non-immunosuppressed baboons were transplanted with transgenic pig kidneys expressing the human complement regulators CD55 and CD59. Recipients were treated with an intravenous infusion of antithrombin III eight hourly (250 units per kg body weight), with or without low molecular weight heparin. Antithrombin-treated recipients had preservation of normal renal function for 4-5 days, which was twice as long as untreated animals, and developed neither thrombocytopenia nor significant coagulopathy during this period. Thus, recombinant antithrombin III may be a useful therapeutic agent to ameliorate both early graft damage and the development of systemic coagulation disorders in pig-to-human xenotransplantation.

Abstract
We examined the organization of the molecular components of the nodal region in spontaneously diabetic BB-Wistar rats. Frozen sections and teased fibers from the sciatic nerves were immunostained for nodal (voltage-gated Na(+) channels, ankyrin(G), and ezrin), paranodal (contactin, Caspr, and neurofascin 155 kDa), and juxtaparanodal (Caspr2, the Shaker-type K(+) channels Kv1.1 and Kv1.2, and their associated subunit Kvbeta2) proteins. All of these proteins were properly localized in myelinated fibers from rats that had been diabetic for 15-44 days, compared to age-matched, nondiabetic animals. These results demonstrate that the axonal membrane is not reorganized, so nodal reorganization is not likely to be the cause of nerve conduction slowing in this animal model of acute diabetes.

Abstract
An 82-year-old woman presented with acute facial paralysis in association with parotid swelling following fine-needle aspiration cytology of a parotid adenolymphoma. Evacuation of a tense haematoma decompressed the nerve and led to complete recovery within 6 months. Additionally, the tumour is no longer evident, either clinically or radiologically, and fine-needle aspiration cytology appears to have been both diagnostic and, inadvertently, therapeutic in this case.

Abstract
The vascular endothelium is the primary site of dysfunction in many diseases, particularly cardiovascular disease. A variety of risk factors, including smoking, hypercholesterolemia, hyperhomocysteinemia, hypertension, and diabetes mellitus, adversely affect endothelial function. Emerging evidence suggests an important role of dietary factors in modulating endothelial function. In particular, n-3 fatty acids, antioxidant vitamins (especially vitamins E and C), folic acid, and L-arginine appear to have beneficial effects on vascular endothelial function, either by decreasing endothelial activation or by improving endothelium-dependent vasodilation in patients at high risk of cardiovascular disease as well as in healthy subjects. These effects may serve as one potential mechanism through which these nutrients reduce the risk of cardiovascular disease, as observed in epidemiologic studies and several clinical trials. This article reviews clinical and experimental evidence regarding the role of these nutrients in modulating endothelial function and their potential to prevent cardiovascular disease.

Abstract
BACKGROUND The genetic modification of pigs is a powerful strategy that may ultimately enable successful xenotransplantation of porcine organs into humans. METHODS Transgenic pigs were produced by microinjection of gene constructs for human complement regulatory proteins CD55 and CD59 and the enzyme alpha1,2-fucosyltransferase (H-transferase, HT), which reduces expression of the major xenoepitope galactose-alpha1,3-galactose (alphaGal). Kidneys from CD55/HT and CD55/CD59/HT transgenic pigs were transplanted into nephrectomised, nonimmunosuppressed adult baboons. RESULTS In several lines of transgenic pigs, CD55 and CD59 were expressed strongly in all tissues examined, whereas HT expression was relatively weak and did not significantly reduce alphaGal. Control nontransgenic kidneys (n=4) grafted into baboons were hyperacutely rejected within 1 hr. In contrast, kidneys from CD55/HT pigs (n=2) were rejected after 30 hr, although kidneys from CD55/CD59/HT pigs (n=6) maintained function for up to 5 days. In the latter grafts, infiltration by macrophages, T cells, and B cells was observed at days 3 and 5 posttransplantation. The recipients developed thrombocytopenia and abnormalities in coagulation, manifested in increased clotting times and an elevation in the plasma level of the fibrin degradation product D-dimer, within 2 days of transplantation. Treatment with low molecular weight heparin prevented profound thrombocytopenia but not the other aspects of coagulopathy. CONCLUSIONS Strong expression of CD55 and CD59 completely protected porcine kidneys from hyperacute rejection and allowed a detailed analysis of xenograft rejection in the absence of immunosuppression. Coagulopathy appears to be a common feature of pig-to-baboon renal transplantation and represents yet another major barrier to its clinical application.

Abstract
BACKGROUND Adhesive interactions between leukocytes and endothelial cells are characteristic of the development of atherosclerotic lesions, but the receptors involved remain to be defined. P-selectin is an adhesion receptor expressed on activated endothelial cells or platelets and was shown to be involved in fatty streak formation in LDL receptor-deficient mice on an atherogenic diet. The main purpose of this study is to examine the role of P-selectin in the spontaneous development of advanced atherosclerosis in apoE-deficient mice. METHODDS AND RESULTS: We intercrossed P-selectin-deficient mice with mice lacking apoE and compared lesion development in apoE-deficient mice with P-selectin (apoE(-/-) P(+/+)) and without P-selectin (apoE(-/-) P(-/-)) that were fed normal mouse chow. At 4 months of age, apoE(-/-) P(-/-) mice had 3. 5-fold smaller aortic sinus lesions than apoE(-/-) P(+/+) mice. These were limited to fatty streaks in the apoE(-/-) P(-/-) mice, whereas 70% of apoE(-/-) P(+/+) lesions contained smooth muscle cells. Significantly more of the aortic sinus circumference was covered by lesions in the apoE(-/-) P(+/+) animals. The P-selectin genotype affected macrophage recruitment, because twice as many mononuclear cells were present in the P-selectin-positive lesions. At 15 months, the lesions progressed to the fibrous plaque stage in both genotypes and spread throughout the aorta, but this process was delayed in apoE(-/-) P(-/-) mice. In the aortic sinus, the lesions of the apoE(-/-) P(-/-) mice were 2.6-fold smaller and less calcified. CONCLUSIONS P-selectin appears to be a key adhesion receptor mediating leukocyte recruitment into lesions and promoting advanced atherosclerosis in apoE-deficient mice.

Abstract
P- and E-selectins are adhesion molecules mediating the first step in leukocyte extravasation. Because their function in leukocyte adhesion is overlapping, we hypothesized that there might be a combined effect of these selectins on the development of atherosclerotic lesions. We bred P- and E-selectin-double-deficient mice onto the low-density lipoprotein receptor (LDLR)-deficient background (LDLR-/- P/E-/-) and compared lesion development in these mice to that in mice wild type for both selectins (LDLR-/- P/E+/+). After 8 wk on atherogenic diet, the LDLR-/- P/E-/- mice developed fatty streaks in the aortic sinus that were five times smaller than those in LDLR-/- P/E+/+ mice. The density of macrophages in the fatty streaks was comparable between LDLR-/- P/E+/+ and LDLR-/- P/E-/- mice. After 22 wk on the diet, the lesions spread throughout the aorta but this process was delayed in LDLR-/- P/E-/- mice. At 37 wk on diet, the lesions progressed to the fibrous plaque stage in both genotypes. However, the lesions in the aortic sinus in LDLR-/- P/E-/- mice were 40% smaller and less calcified than those of LDLR-/- P/E +/+ mice. Our results suggest that P- and E-selectins together play an important role in both early and advanced stages of atherosclerotic lesion development.

Abstract
A subcutaneous nodule composed of heterotopic glial tissue is reported. The lesion was present in the subcutaneous tissue of the chest wall in a 2-year-old female. Histologically it was composed of loosely textured fibrillary neuroglial tissue in a densely hyalinized collagenous stroma. Immunohistochemical staining for glial fibrillary acidic protein was positive. The possible origin of this soft tissue glial heterotopia is discussed and the subject of heterotopic glial tissue is reviewed.

Abstract
The value of colonoscopy in the diagnosis and management of lower gastro-intestinal haemorrhage was assessed in 107 patients who were examined during a 2-year period. The main indications were to define uncertain radiological findings, to further investigate the cause of bleeding in patients with normal barium studies and to carry out polypectomy. Radiological lesions were confirmed in 27, defined in 12, and refuted in 14 patients. Twenty-eight lesions were demonstrated on colonoscopy which were not diagnosed by barium enema or sigmoidoscopy. A diagnosis was made by colonoscopy in more than two-thirds of the patients with frank blood loss and normal radiographs. In cases of occult bleeding it was farless helpful. Colonoscopy significantly improved diagnosis and management of gastro-intestinal bleeding when the cause was in doubt after standard investigations. In addition, 37 polyps were removed through the colonoscope from 30 patients.

Abstract
During the examination of the colon by fibre-optic colonoscopy in 200 consecutive patients it was possible to reach the caecum or suspected lesion in 80% of cases. Careful bowel preparation, sedation and detailed attention to techniques described are necessary for safe and successful performance of this procedure. In 85% of examinations, colonoscopy produced positive results including the definition of uncertain radiological lesions in 45 patients, finding of a cause for rectal bleeding not shown on barium studies in 15 patients, the assessment of inflammatory bowel disease in 28 patients, and the removal of polyps in 40 patients. Important was the finding of a normal colon in 49 cases, which obviated unnecessary surgery. Colonic perforation occurred in 2 patients. The limitations and complications of the procedure must be realised, but it is concluded that the colonoscope provides a valuable and effective means of diagnosis and therapy of lesions in the large bowel.

Abstract
Abstract
This paper draws attention to the fact that the left renal vein or one of its major tributaries may be ligated without apparent impairment of function of the left kidney. This information has been of great value in constructing splenorenal shunts in operations for portal decompression. Other situations in which this information might be of value are suggested.
