Abstract
Childhood adrenoleukodystrophy (cALD) is a metabolic disorder in which very long-chain fatty acids (VLCFA) accumulate due to ALD protein gene defects, ultimately leading to lipotoxicity-induced neuroinflammatory demyelinating disease. Therefore, we examined VLCFA-mediated alterations in the metabolism of lipoxidative enzymes and inflammatory mediators in the cALD brain. 5-Lipoxygenase (5-LOX)-derived leukotrienes were significantly elevated in all the areas of white matter in the cALD brain. Unlike cyclooxygenase-2 expression, which was moderately high only in the plaque area, expression of 5-LOX and cytosolic phospholipase A2 was prominent in all the areas. This lipoxidative burden in the cALD brain was further shown by reduced levels of glutathione and enhanced expression of heat shock protein-70/manganese superoxide dismutase. These pathological observations were confirmed through in vitro mechanistic investigation. After increasing VLCFA through silencing Abcd1+Abcd2 in mouse primary astrocytes, enhanced expression of 5-LOX was observed, and this increased expression was blocked by treatment with monoenoic fatty acids. These results link the previously observed accumulation of VLCFA in cALD to the 5-LOX enzyme pathway. A similar increase in 5-LOX expression in astrocytes was also detected following treatment with exogenous VLCFA (C26:0). In sum, through 5-LOX activation, VLCFA accumulation causes a lipotoxic response consistent with cALD brain pathology.

Abstract
Filters rated as having a 0.2-microm pore size (0.2-microm-rated filters) are used in laboratory and manufacturing settings for diverse applications of bacterial and particle removal from process fluids, analytical test articles, and gasses. Using Hydrogenophaga pseudoflava, a diminutive bacterium with an unusual geometry (i.e., it is very thin), we evaluated passage through 0.2-microm-rated filters and the impact of filtration process parameters and bacterial challenge density. We show that consistent H. pseudoflava passage occurs through 0.2-microm-rated filters. This is in contrast to an absence of significant passage of nutritionally challenged bacteria that are of similar size (i.e., hydrodynamic diameter) but dissimilar geometry.

Abstract
OBJECTIVE The study was aimed to evaluate the relationship between pharmacy supply, self-reported treatment adherence and HIV viral load in HIV-infected children. METHODS A retrospective (52 weeks) cohort study was conducted through the review of the existing databases. Pharmacy supply was classified as "home delivery" when the medications were delivered home and as "in pharmacy pick-up" when they were picked up at the pharmacy. Adherence was assessed through retrospective (3 days recall) self-report. Fisher's exact model, univariate and multivariate logistic regression analyses were used. SETTINGS The study collected data on 140 HIV-infected children (<18 years). Adherence, pharmacy supply information and HIV viral loads were obtained from clinical and research databases. PATIENTS The data from 127 HIV-infected children (60 boys and 67 girls; mean age 9.9 years) were collected. MAIN OUTCOME MEASURES Complete adherence (100%) was reported in only 24% of patients. With 40% of patients being rarely or never completely adherent, 64% of children achieved undetectable viral loads during the study period. RESULTS No association between pharmacy supply and self-reported adherence was found (p = 0.605). Self-reported adherence (p = 0.0328) and age (p = 0.025) were the significant predictors of reaching undetectable viral loads. Adolescents (>13 years) were significantly less likely to reach undetectable viral loads than children under 13 years (odds ratio 0.38; 95% CI 0.16 to 0.89). CONCLUSION In our study, pharmacy supply was not associated with self-reported adherence. Most importantly, adherence and age were significant predictors of reaching undetectable viral loads.

Abstract
Background Traumatic brain injury (TBI) is a major cause of preventable death and serious morbidity in young adults. This complex pathological condition is characterized by significant blood brain barrier (BBB) leakage that stems from cerebral ischemia, inflammation, and redox imbalances in the traumatic penumbra of the injured brain. Once trauma has occurred, combating these exacerbations is the keystone of an effective TBI therapy. Following other brain injuries, nitric oxide modulators such as S-nitrosoglutathione (GSNO) maintain not only redox balance but also inhibit the mechanisms of secondary injury. Therefore, we tested whether GSNO shows efficacy in a rat model of experimental TBI. Methods TBI was induced by controlled cortical impact (CCI) in adult male rats. GSNO (50 μg/kg body weight) was administered at two hours after CCI. GSNO-treated injured animals (CCI+GSNO group) were compared with vehicle-treated injured animals (CCI+VEH group) in terms of tissue morphology, BBB leakage, edema, inflammation, cell death, and neurological deficit. Results Treatment of the TBI animals with GSNO reduced BBB disruption as evidenced by decreased Evan's blue extravasation across brain, infiltration/activation of macrophages (ED1 positive cells), and reduced expression of ICAM-1 and MMP-9. The GSNO treatment also restored CCI-mediated reduced expression of BBB integrity proteins ZO-1 and occludin. GSNO-mediated improvements in tissue histology shown by reduction of lesion size and decreased loss of both myelin (measured by LFB staining) and neurons (assayed by TUNEL) further support the efficacy of GSNO therapy. GSNO-mediated reduced expression of iNOS in macrophages as well as decreased neuronal cell death may be responsible for the histological improvement and reduced exacerbations. In addition to these biochemical and histological improvements, GSNO-treated injured animals recovered neurobehavioral functions as evaluated by the rotarod task and neurological score measurements. Conclusion GSNO is a promising candidate to be evaluated in humans after brain trauma because it not only protects the traumatic penumbra from secondary injury and improves overall tissue structure but also maintains the integrity of BBB and reduces neurologic deficits following CCI in a rat model of experimental TBI.

Abstract
OBJECTIVE Enzymes involved in the oxidative metabolism of n-6 polyunsaturated fatty acids, like lipoxygenase (LOX) and cyclooxygenase (COX), are significant in the pathogenesis of colorectal cancer. Of these enzymes, 15-LOX-1 is expressed in colon. Aim of this article is to describe the role and regulation of 15-LOX-1 in colorectal cancer and highlight its importance in cancer therapeutics. METHODS For our electronic literature research in PubMed and MEDLINE, key words related to 15-LOX-1 and colorectal cancer were used to find articles for this review. RESULTS From the evidences, we believe that 15-LOX-1 has anti-carcinogenic effects in colorectal cancer, dependent or independent of its metabolites, and is manifested through downstream pathways involving cGMP, PPAR, p53, p21 and NAG-1, increasing apoptosis and decreasing proliferation in cancer cells. Regulation of 15-LOX-1 expression is achieved at transcription level by global histone acetylation and may also be dependent on GATA-6, IL-4 and IL-13. Positive relationship exists between 15-LOX-1 and survival in colorectal cancer. CONCLUSION Evidences strongly support that therapeutic modulation of 15-LOX-1 may be a key to the treatment of colorectal cancer. However, it is still undecided whether the up-regulation of 15-LOX-1 alone can be sufficient to treat colorectal cancer and further studies are awaited.

Abstract
BACKGROUND In animal models, ischemia reperfusion (IR) injury triggers membrane lipid degradation and accumulation of lipoxidative exacerbations in neurovascular unit, leading to blood brain barrier (BBB) damage and neurologic deficits. In this study, we investigated whether impeding membrane lipid breakdown by inhibiting secretory phospholipase A2 (sPLA2) activity reduces BBB leakage, leading to neuroprotection and functional recovery. METHODS Focal cerebral IR injury was induced by middle cerebral artery occlusion (MCAO) in adult male rats. A sPLA2 inhibitor, 7,7-dimethyleicosadienoic acid (DEDA), was administered following IR injury. DEDA-treated animals were compared with vehicle-treated in terms of BBB leakage, edema, infarct volume, and neurological deficit. Membrane lipid degradation and the expression/activity of sPLA2 were also assessed. The role of one of the sPLA2 products, arachidonic acid (AA), on the morphology of the differentiated neuronal cell PC12 was examined by light microscopy. RESULTS Treatment with DEDA after IR injury not only reduced BBB leakage but also decreased infarct volume and improved neurologic function. The treatment attenuated both the activity of sPLA2 and the levels of sPLA2-derived oxidized products. The metabolites of lipid oxidation/peroxidation, including the protein carbonyl, were reduced as well. The treatment also restored the levels of glutathione, indicating attenuation of oxidative stress. In vitro treatment of PC12 cells with DEDA did not restore the AA-mediated inhibition of neurite formation and the levels of glutathione, indicating that effect of DEDA is up stream to AA release. CONCLUSION sPLA2-derived oxidative products contribute to significant neurovascular damage, and treatment with sPLA2 inhibitor DEDA ameliorates secondary injury by reducing exacerbations from lipoxidative stress.

Abstract
BACKGROUND In inmunocompetent hosts, cytomegalovirus (CMV) infection is generally asymptomatic. It may however present as infectious mononucleosis. Serious complications have rarely been reported. We report three cases of acute CMV hepatitis in immunocompetent men for the first time from Bangladesh. All three presented to us with features of acute hepatitis of variable duration preceded by prodrome. Other probable causes of acute hepatitis were ruled out and none had any clinical stigmata of cirrhosis. All the three patients underwent uneventful recovery. Although more common in the immunocompromised, CMV can occasionally produce symptomatic hepatitis in the immunocompetent host. Disease is self limiting, but supportive measures are needed.

Abstract
BACKGROUND Although there is much consensus, certain controversies still exist regarding the pathology of Fournier's gangrene. The purpose of this study was to determine the prevalence of the disease in the catchment area of the three teaching hospitals, to identify the systemic predisposing factors and local aetiological factors, and to assess the recommended role of aggressive surgical debridement as a part of treatment. MATERIALS AND METHODS This prospective study was conducted in the surgical departments of three tertiary care hospitals of the Khyber Medical University, Peshawar, Pakistan, from 1 January 2002 to 30 June 2007. Detailed history and examination of all patients were carried out to reach the diagnosis of Fournier's gangrene. After initial resuscitation, patients were treated aggressively, including surgical debridement. RESULTS Sixty patients were studied in the study period. The male to female ratio was 5:1. The age range was 20-75 years with mean 47+17.4 (SD) years. The socioeconomic status of patients was poor (the average income was less than $50 per week) in 36 (60%) and 24 (40%) were middle class (the average income being $50-100 per week). Thirty-nine patients (65%) presented in the hot humid months of the year. Extent of the disease was scrotum in 18 patients (30%), perineum in 30 (50%) and abdominal wall in 12 (20%). Systemic predisposing factors identified in our study were diabetes mellitus in 20 (33.33%) patients, chronic alcohol abuse in two (3.33%) and long-standing steroid therapy in four (6.67%) while in 34 patients (56.67%) no cause was identified. The local aetiological origin of Fournier's gangrene was urogenital in 14 (23.33%) patients, anorectal in 10 (16.67%) and cutaneous in 8 (13.33%) and no local pathologies could be identified in 28 (46.67%) patients. The mean time interval between first symptom and initial treatment was 2.5 days with a range of 1-7 days. Number of debridement sessions per patient was 2-6 (mean, 3.15). Mean hospital stay was 31+7 (SD) with a range of 10-50 days. Morbidity was 80%. Four patients (6.67%) died. Three of these patients presented to hospital 5-6 days too late. CONCLUSION Fournier's gangrene is not an uncommon disease in South Asia. Systemic predisposition such as diabetes mellitus, long-standing steroid therapy, chronic alcoholism and even the hot humid season can contribute to this dreadful disease. Local causes in the form of urogenital, anorectal and cutaneous disorders may trigger this disease in some patients. Early recognition of disease and aggressive surgical debridement are the main treatments.

Abstract
Experimental studies in our laboratory have established the role of delta-aminolevulinic acid dehydratase (ALAD) and matrix gamma-carboxyglutamic acid (MGP) gene polymorphisms in the etiology of lead toxicity. Polymorphisms in these genes influenced the levels of lead in subjects exposed to this metal. In extension to our studies, we aimed to investigate the possible role of these proteins in evolution by studying the phylogenetic relationship and divergence of ALAD and MGP genes using computational phylogenetic methods. The human ALAD and MGP protein sequences from various species were retrieved from Swiss-Prot database and were compared using Basic Local Alignment Search Tool. Multiple sequence alignment was carried out using ClustalW with defaults, and phylogenetic trees for both the genes were built using neighbor-joining method as in Mega software. Our study indicated that ALAD is a highly conserved protein with the same metal binding site distributed in all the phyla (from archaea to chordates). Phylogenetic analysis of MGP gene revealed that it had an important role in the evolution of endogenous skeleton in contrast to exoskeleton of insects. Occurrence of these genes in evolution with conserved metal binding sites strengthens the role of ALAD and MGP genes in regulating heme biosynthesis and mineralization, respectively, in evolution and helps in better understanding of lead poisoning.

Abstract
e15098 Background: FOLFOX4 is a standard chemotherapy for mCRC. FFG has shown substantial activity in mCRC. This trial compared the safety and efficacy of FFG and FOLFOX4 regimens in patients (pts) with mCRC. B was added to each arm after FDA approval in 2004 as first-line treatment of mCRC. Methods: Pts with mCRC, chemonaïve except for adjuvant treatment, were randomized to two treatment arms: FFG given weekly for 6 weeks of an 8-week cycle; FOLFOX4 had a 2-week cycle. Pts in both groups received B at 5 mg/kg every 2 weeks. Treatment continued until disease progression. Planned enrollment was 150 pts. Primary endpoint was overall response rate (ORR); secondary endpoints included toxicity, overall survival (OS), and time to progression (TTP). Response was assessed by RECIST. Post-hoc analysis of disease control rate (DCR) was added. Results: Forty-two pts (18 pts given B) were randomized to each arm. Thirty-one cycles of FFG and 248 cycles of FOLFOX4 were delivered. FFG produced greater myelosuppression than FOLFOX4. Two cases each of MI and DVT were observed in the FOLFOX4(B) subgroup; one pt had DVT with FFG alone. The incidence of gastrointestinal hemorrhage was low and similar for FFG and FOLFOX4. Peripheral neuropathy was highest in the FOLFOX4(B) subgroup. ORR and DCR were significantly greater for FOLFOX4(B) than for FFG(B). Median TTP and OS were not statistically different for FFG and FOLFOX4 groups. The trial was stopped due to low enrollment; planned statistical power was not achieved. Conclusions: FFG and FOLFOX4 regimens were generally well tolerated, with greater neuropathy in FOLFOX4 and greater myelosuppression in FFG. ORR was greatest in the FOLFOX4(B) subgroup. TTP and OS results comparing FFG and FOLFOX4 groups were inconclusive due to low enrollment. Rapid changes in mCRC “standard of care” during this trial may have constrained pt accrual.

Abstract
Acute myocardial infarction is a cause of neonatal collapse. The diagnosis is suggested by ischaemic electrocardiography, raised cardiac enzymes and deteriorating cardiac function and should be considered in severe neonatal cardiac dysfunction without other identifiable causes. This paper presents four cases of neonatal myocardial infarction treated with veno-arterial extracorporeal membrane oxygenation (VA ECMO) for cardiorespiratory support. The paper illustrates that left ventricular function may recover after neonatal myocardial infarction if it can be supported for long enough, and that early ECMO referral may be of benefit.
