Abstract
A systematic investigation on the isotopic and elemental signature, for both stable and radioactive elements, and mineral contents was performed to examine the characteristics of subsurface formations collected at different depths between 3.962 km and 4.115 km around deep-laying coal seams located under the Marmarica plateau in Egypt. Concentrations of major and minor oxides (Na2O, MgO, Al2O3, SiO2, SO3, K2O, CaO, TiO2, MnO, ΣFeO + Fe2O3, SrO, ZrO2, and BaO) were determined by X-ray fluorescence and dependencies among these concentrations revealed the type and sort of the formations. Organic contents were determined by Fourier Transform infrared spectroscopy to investigate the variation of the CO/CC bonding ratio with depth. Rare earth elements (REE), specifically Y, Sc, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu were determined by inductively coupled plasma mass spectrometry while actinoids were detected by the radioactive decay of its daughter nuclei. The results showed a high trapping of REE elements and actinoids in layers above the coal seams which indicates the occurrence of aqueous flow followed by possible sorption in these layers. The mobility of the fluid was investigated using the process radioactive decay series between Ra226 and Ac228 from one side and their daughters from the other side.

Abstract
Human exposure to mycotoxins is almost inevitable as mycotoxins are naturally occurring contaminants of large portion of food and feed. Depending on the type of mycotoxins, inter-individual mycotoxin adsorption, bioaccumulation, distribution, metabolism and excretion, can cause serious adverse health effects. Therefore, continuous biomonitoring studies of population exposure to mycotoxins are needed. Here we describe a multi-analyte approach for the detection and quantification of 20 mycotoxins in human serum using ultra-performance liquid chromatography-electrospray/tandem mass spectrometry operated in targeted multiple reaction monitoring mode. The validated method was used to assess occurrence of mycotoxins in serum samples of 46 residents of Qatar. Mycotoxins that were detected with high incidence were HT-2 toxin (13.0%), sterigmatocystin (10.9%) and 3-acetyldeoxynivalenol (6.5%). Also, co-exposure to several mycotoxins was noticed in the analysed samples. Our results show that strict food quality control is needed to remove mycotoxin contaminated food from the market in order to minimise human exposure to mycotoxins.

Abstract
Activity concentrations of 238U, 232Th and 40K in raw and waste petroleum materials (Egypt and Kuwait) were measured using gamma ray spectrometer. The average values of 226Ra, 232Th and 40K were 21.1 ± 3.2, 7.6 ± 1.3 and 88.4 ± 8.2 Bq kg-1 for Egyptian samples while for Kuwaiti samples, they were 25.2 ± 3.4, 6.1 ± 2.2 and 67.8 ± 6.4 Bq kg-1, respectively. All samples had activity less than the exemption level recommended by the International Atomic Energy Agency. Moreover, radiological indices of radium equivalent, external, internal, alpha and gamma indices and radiation dose as well were calculated and their values were lower than the recommended regulatory limits. Thus, radiation exposure to petroleum materials did not present a significant radiological hazard.

Abstract
BACKGROUND AND PURPOSE Differentiating pediatric-onset neuromyelitis optica spectrum disorder from acute disseminated encephalomyelitis could be challenging, especially in cases presenting with only brain manifestations. Our purpose was to investigate brain MR imaging features that may help distinguish these 2 entities. MATERIALS AND METHODS We retrospectively examined initial brain MR imaging studies of 10 patients with pediatric-onset neuromyelitis optica spectrum disorder (female/male ratio, 7:3) and 10 patients with acute disseminated encephalomyelitis (female/male ratio, 2:8). The mean age of the patients was 10.3 ± 5.6 and 8.7 ± 5.3 years, respectively. Brain lesions were evaluated with respect to location, extent, expansion, T1 hypointensity, contrast enhancement/pattern, and diffusion characteristics. The χ2 test (Yates or Fisher exact χ2tests) was used to compare differences between groups. RESULTS Cerebral subcortical ± juxtacortical and pons ± middle cerebellar peduncle were the most frequent locations involved in both neuromyelitis optica spectrum disorder (n = 5 and 4, respectively) and acute disseminated encephalomyelitis (n = 9 and 7, respectively). Thalamic lesions were more frequent in acute disseminated encephalomyelitis (P = .020) and were detected only in 1 patient with neuromyelitis optica spectrum disorder. None of the patients with neuromyelitis optica spectrum disorder had hypothalamic, internal capsule, or cortical lesions. The internal capsule involvement was found to be significantly different between groups (P = .033). There was no significant difference in terms of extent, expansion, T1 hypointensity, contrast enhancement/pattern, and diffusion characteristics. CONCLUSIONS Although there is a considerable overlap in brain MR imaging findings, thalamic and internal capsule involvement could be used to differentiate pediatric-onset neuromyelitis optica spectrum disorder from acute disseminated encephalomyelitis.

Abstract
Zika virus (ZIKV) cases have been detected across the United States (US) and locally acquired cases have been reported in Florida. Currently, there are no ZIKV screening guidelines and no data on the incidence among organ donors in the US. This retrospective study was conducted at Jackson Memorial-Miami Transplant Institute. Positive ZIKV tests in local deceased organ donors were investigated from 6/2016 to 1/2017. We evaluated demographics and risk factors for ZIKV infection among organ donors and transplant outcomes among recipients of donors with positive ZIKV testing. One hundred forty-two donors were analyzed. Ten percent had traveled to ZIKV-endemic countries and 19% had outdoor occupations. Only 3% had positive ZIKV IGG. None had a positive ZIKV IGM or PCR. ZIKV-positive donors were more likely to have traveled to ZIKV-endemic countries (50% vs. 9%, P = .05). The kidneys from a ZIKV-positive donor were transplanted in our hospital with no 6-month rejection, graft failure, or death in the recipients. Our study demonstrated a low prevalence of ZIKV among deceased donors in our community. Despite local ZIKV transmission, ZIKV was more common in donors who traveled to ZIKV-endemic countries. This cohort demonstrated excellent outcomes in recipients of ZIKV IGG-positive donors. However, larger studies are needed.

Abstract
Digital pathology has advanced substantially over the last decade with the adoption of slide scanners in pathology labs. The use of digital slides to analyse diseases at the microscopic level is both cost-effective and efficient. Identifying complex tumour patterns in digital slides is a challenging problem but holds significant importance for tumour burden assessment, grading and many other pathological assessments in cancer research. The use of convolutional neural networks (CNNs) to analyse such complex images has been well adopted in digital pathology. However, in recent years, the architecture of CNNs has altered with the introduction of inception modules which have shown great promise for classification tasks. In this paper, we propose a modified 'transition' module which encourages generalisation in a deep learning framework with few training samples. In the transition module, filters of varying sizes are used to encourage class-specific filters at multiple spatial resolutions followed by global average pooling. We demonstrate the performance of the transition module in AlexNet and ZFNet, for classifying breast tumours in two independent data-sets of scanned histology sections; the inclusion of the transition module in these CNNs improved performance.

Abstract
Background According to our literature analysis, there are no data focused on spermatozoa emotional representations in childless men and data on the emotional repercussions of a diagnosis of infertility on men are still scarce. Thus, in this work, we investigated what the presence or absence of spermatozoa in the semen symbolize for men. Material and methods To answer this question, 441 childless heterosexual men participated in an anonymous, prospective, Internet-based survey. Results In response to the question “What would having a high or normal sperm count symbolize for you?” the most frequent answer was “ability to father a child”. Men living with a partner were significantly more likely than single men to answer “ability to father a child” (p < 0.05) and less likely to answer “virility” and/or “ability to have an erection/ejaculation” (p = 0.001). In response to the question “If you found out that you had a low sperm count or no spermatozoa at all, how would you feel?”, most of the men stated that they would be disappointed. Men living with a partner were more likely to state that they would feel ashamed (p < 0.05) or guilty with regard to their partner (p < 0.0001). Conclusions These preliminary results should help us to improve (i) the way that male infertility is announced (it is easier to find the right words if one understands the possible importance of having a high sperm count) and (ii) the psychological, marital and sexual counselling provided to men with a diagnosis of infertility.

Abstract
Since Antiquity, women who expulse a large quantity of liquid during sexual stimulation have remained a mystery. This phenomena is usually called "squirting". Many physicians have proposed different explications, however, there are very few scientific publications and their conclusions are discordant. Today, squirting is fashionable in the media, and some recent studies have brought new information. Through medical publications, we present the conclusions concerning the origin and the nature of squirting, the psychological experience of these squirting women and the feelings of their partners.

Abstract
Résumé
Introduction
Dans l’azoospermie obstructive (AO), les taux d’extraction chirurgicale de spermatozoïdes sont élevés. Cependant, en ce qui concerne les issues des ICSI (Intra cytoplasmic Sperm Injection) chirurgicales, les données de la littérature divergent. Quels sont, dans notre équipe, les taux d’extraction de spermatozoïdes après aspiration épidydimaire (MESA) et après extraction testiculaire (TESE) dans l’AO ? Les taux de grossesses, les taux de fausses couches spontanées et d’accouchements diffèrent-ils en fonction de l’origine du sperme ?
Matériels et méthodes
L’étude a rétrospectivement inclus 48 couples dont l’homme présente une azoospermie obstructive pure et ayant bénéficié d’un prélèvement chirurgical de spermatozoïdes associant systématiquement MESA et TESE. Les ICSI ont été réalisées de manière asynchrone. À chaque fois que cela était possible, la première ICSI a été réalisée avec des spermatozoïdes épididymaires.
Résultats
Pour les 48 couples, 99 ICSI ont été réalisées. Quinze couples ont réalisé 24 ICSI-TESE car l’aspiration épididymaire était négative. Onze couples ont réalisé 20 ICSI-TESE car la qualité du prélèvement épididymaire n’était pas satisfaisante (vitalité spermatique réduite le plus souvent). Vingt-deux couples ont réalisé 22 ICSI-MESA en première intention puis en cas d’échec, 11 couples ont réalisé 12 ICSI-MESA et dix couples ont réalisé 20 ICSI-TESE. Alors que les nombres d’ovocytes injectés (7,1±4,1 vs 6,9 ±3,6 P: 0,8) et d’embryons obtenus (4,5±3,0 vs 4,7±2,7; P: 0,7) ne sont pas significativement différents dans les deux groupes d’ICSI, les nombres d’embryons de top qualité (2,4±1,9 vs 3,6±2,0 P: 0,005) et d’embryons congelés (0,9±1,8 vs 1,7±1,9 P: 0,04) sont significativement supérieurs dans le groupe TESE. Le nombre de grossesse par ponction est supérieur dans le groupe TESE (58,5 % vs 26,5 %, P: 0,002).
Conclusion
L’approche de notre centre a la particularité d’associer systématiquement un prélèvement testiculaire au prélèvement épididymaire chez tout homme présentant une azoospermie obstructive alors que la plupart des autres études rapportées se limitent à l’exploration épididymaire si cette dernière est positive lors de l’examen extemporané. Alors que classiquement, on rapporte 100% de positivité lors du prélèvement épididymaire chez l’homme atteint d’une azoospermie obstructive, dans notre étude, plus de la moitié des explorations épididymaires s’est avérée inexploitable. La qualité embryonnaire et les taux de grossesses sont meilleurs avec des spermatozoïdes testiculaires. L’association de ces 2 sites de prélèvement (MESA et TESE) peut être complémentaire et utile pour le couple et l’issue de sa prise en charge en AMP sans pour autant entraîner un sur-risque pour l’homme dans les suites de la chirurgie.

Abstract
OBJECTIVE To evaluate the reproductive safety and long-term efficacy of hysteroscopic superficial endometrial resection for polypoid endometrium in symptomatic patients (menorrhagia, dysmenorrhea and unexplained infertility). PATIENTS AND METHODS The present retrospective descriptive case series study included 44 patients of reproductive age who underwent superficial hysteroscopic endometrial resection between January 1st, 2004 and December 31, 2009. Reproductive outcome, and the patients' perceptions of menstrual symptoms after the surgical intervention were collected from the clinical notes and a semi-structured telephone interview. RESULTS Of the patients presenting abnormal uterine bleeding, 59% reported long-term improvement of this symptom; of those with dysmenorrhea, 52% reported long-term relief. Among 26 infertile women who wanted to become pregnant immediately after the procedure, 58% succeeded (n=15), with a live-born rate of 38%. The pregnancy rate in primary and secondary infertility cases was respectively 53% (n=8/15) and 64% (n=7/11). CONCLUSION Superficial endometrial resection is an alternative for treating polypoid endometrium when it is associated with menorrhagia, dysmenorrhea and infertility. It treats menstrual symptoms successfully, with no adverse impact on fertility.

Abstract
We describe here for the first time the characterization of family member of netrins, netrin-4 and its receptor neogenin, during the development of the placenta. By using western blots and RT-PCR, we demonstrated the presence of netrin-4 and its receptor neogenin protein as well as their transcripts. Using immunohistochemistry, we studied the distribution of netrin-4 and neogenin in both the first trimester and term placenta. We observed staining of netrin-4 in villous and extravillous cytotrophoblasts, syncytiotrophoblast, and endothelial cells whereas staining in stromal cells was faint. In decidua, we observed netrin-4 labelling in glandular epithelial cells, perivascular decidualized cells, and endothelial cells. However, neogenin was absent in villous and extravillous cytotrophoblasts and was expressed only on syncytiotrophoblast and placental stromal cells in the first trimester and at term placenta. The pattern of distribution suggests that a functional netrin-4-neogenin pathway might be restricted to syncytiotrophoblasts, mesenchymal cells, and villous endothelial cells. This pathway function might vary with its localization in the placenta. It is possibly involved in angiogenesis, morphogenesis, and differentiation.

Abstract
Since the inception of Assisted Reproductive Technology (ART), knowing the moment of ovulation has always been a priority. Initially, the monitoring was accomplished by observing the luteinizing hormone (LH) surge just before ovulation. Currently, in all ART facilities, the monitoring of all stimulated ovulatory cycles is done by using the conventional two-dimensional (2D) ultrasound to measure follicle diameter and by drawing blood tests that measure estradiol, progesterone, and luteinizing hormone levels. These exams allow determination of the numbers and quality of growing ovarian follicles and evaluation of follicle maturity before choosing the appropriate time for ovulation triggering. The monitoring of ovulatory cycles has now become enhanced with the arrival of new software called SonoAVC. This software allows the utilization of 3D blocks to immediately calculate the total number and volume of the follicles inside the ovary. This automatic approach is faster, precise, and more efficient. It also has better reproducibility than the classical 2D diameters. Furthermore, certain ART professionals envision that by using the SonoVac technology, patients will no longer need to be monitored with regular ultrasounds and with systematic hormonal testing.

Abstract
OBJECTIVES To evaluate fertility outcome after laparoscopic management of endometriosis in an infertile population. MATERIALS AND METHODS A retrospective analysis of 64 patients presenting more than one year infertility and a pregnancy-wish associated with minimal to severe endometriotic lesions (stage I to IV according to the revised American Fertility Society (rAFS) classification), treated using laparoscopic surgery in order to remove the entire lesions. We excluded women under 20 years and over 40, as well as those with other infertility factors (tubal non endometriosis-related, hormonal or sperm). Fertility of the remaining 34 patients was studied in relation to endometriosis stage and to pregnancy's mode (spontaneous or induced). RESULTS Pregnant women percentage was 65% (22 patients) within a 8.5 months (quartiles: 3; 15.5) [range: 1; 52] post-surgical time, and 86.5% pregnancies issued with a delivery. The rate of pregnant women depended on stage of endometriosis (89% for stages I-II, and 56% for stages III-IV). Sixty percent pregnancies were spontaneous within a 5 months (3; 9) [1; 52] post-surgical time to pregnancy average. When pregnancies were obtained with assisted reproductive techniques, the median post-surgical time to pregnancy was 12 months (9; 22) [2; 31]. Among women with stages I-II endometriosis, the median post-surgical time to pregnancy was 2 months when spontaneous and 20.5 months when induced (P=0.007). In case of stages III-IV endometriosis, pregnancy's delay was 8 and 12 months respectively (P=0.79). Among the 21% women who had had an induced pregnancy failure before surgery, 71% became pregnant and 80% spontaneously. Eighteen patients (53%) had an ovarian endometrioma and 50% of them became pregnant. Among the 4 patients who had colorectal endometriosis requiring colorectal resection, 1 pregnancy was obtained. CONCLUSIONS These findings suggest that in a context of more than one year infertility only related to endometriosis, it is reasonable to offer these patients a complete operative laparoscopic treatment of their lesions, which enables 65% of them to be pregnant within a 8.5 months post-surgical median time to pregnancy and spontaneously in 60%. In case of stages I-II endometriosis we suggest a spontaneous pregnancy try during 8 to 12 months before starting induced pregnancy therapeutics instead of stages III-IV endometriosis where induced methods should be used after only 6 or 8 months.

Abstract
Posttransplantation lymphoproliferative disorders (PTLD) presenting clinically in the skin are rare and usually of B-cell phenotype. Only 7 cases of cutaneous T-cell PTLD have been previously reported, mostly mycosis fungoides type, with no known cases of "cutaneous" presentation by CD30 (Ki-1) anaplastic large cell lymphoma (ALCL). The case reported is a 59-year-old male who developed multiple skin nodules on the right leg, 6 years following renal transplantation. Initial biopsy showed ALCL involving the dermis with a background rich in neutrophils. The neoplastic cells were of T-cell phenotype, strongly CD30 with typical staining, and BCL-2 positive, but P53 negative. No EBV was detected by IHC, ISH, or DNA analysis. One year later, he developed painful subcutaneous nodules with surrounding erythema, resembling deep pustules or panniculitis, which on biopsy showed preferential involvement of the subcutaneous fat and prominent component of neutrophils. Twenty-two months following diagnosis, he died of cardiac failure with terminal myocardial infarct. There was however no clinical evidence of systemic spread of the lymphoma.This report adds to the clinical and morphologic spectrum of these rare "cutaneous" lymphomas of T-cell lineage arising in the posttransplantation setting, and suggests that EBV does not play a role in their pathogenesis.

Abstract
Keloid scars are benign fibroproliferative growths that respond poorly to treatment. This study sought to determine the efficacy of three different glucocorticoids (triamcinolone, methylprednisolone and dexamethasone) in altering human keloid scar tissue implanted in athymic mice. Keloid tissue obtained from three patients (one man and two women) who sought cosmetic removal of their scars was implanted into athymic mice for a duration of 15 or 30 days. The keloid tissue was examined histopathologically and evaluated by a dermatopathologist who was blinded to sample identity and who was using predetermined qualitative scoring criteria. The appearance of central calcification, granulation tissue, foreign body granulomatous reaction and acute inflammatory reaction complicated the comparison of the keloid tissue samples. However, on the basis of observations reported in the present paper, it appears that triamcinolone should remain the treatment of choice for keloid scars. The athymic mouse model that is used for studying keloid scars is the best available approach to in vivo studies; however, limitations identified in this study confound the interpretation of experimental data. Ideally, promising and novel therapies should be investigated clinically.

Abstract
OBJECTIVE To determine modifiable risk factors for nosocomial Clostridium difficile-associated diarrhea (CDAD). DESIGN Case-control study. SETTING 300-bed tertiary-care hospital. PARTICIPANTS Hospital inpatients present during the 3-month study period. METHODS Case-patients identified with nosocomial CDAD over the study period were compared to two sets of control patients: inpatients matched by age, gender, and date of admission; and inpatients matched by duration of hospital stay. Variables including demographic data, comorbid illnesses, antibiotic exposure, and use of gastrointestinal medications were assessed for case- and control-patients. Conditional logistic regression was performed to identify risk factors for nosocomial CDAD. RESULTS 27 case-patients were identified and were compared to the two sets of controls (1:1 match for each comparison set). For the first set of controls, use of ciprofloxacin (odds ratio [OR], 5.5; 95% confidence interval [CI 95], 1.2-24.8; P=.03) was the only variable that remained significant in the multivariable model. For the second set of controls, prior exposure to cephalosporins (OR, 6.7; CI 95, 1.3-33.7; P=.02) and to ciprofloxacin (OR, 9.5; CI 95, 1.01-88.4; P=.05) were kept in the final model. CONCLUSIONS Along with cephalosporins, prior quinolone use predisposed hospitalized patients to nosocomial CDAD. Quinolones should be used judiciously in acute-care hospitals, particularly in those where CDAD is endemic.

Abstract
Peptide deformylase (PDF) is an essential bacterial metalloenzyme which deformylates the N-formylmethionine of newly synthesized polypeptides and as such represents a novel target for antibacterial chemotherapy. To identify novel PDF inhibitors, we screened a metalloenzyme inhibitor library and identified an N-formyl-hydroxylamine derivative, BB-3497, and a related natural hydroxamic acid antibiotic, actinonin, as potent and selective inhibitors of PDF. To elucidate the interactions that contribute to the binding affinity of these inhibitors, we determined the crystal structures of BB-3497 and actinonin bound to Escherichia coli PDF at resolutions of 2.1 and 1.75 A, respectively. In both complexes, the active-site metal atom was pentacoordinated by the side chains of Cys 90, His 132, and His 136 and the two oxygen atoms of N-formyl-hydroxylamine or hydroxamate. BB-3497 had activity against gram-positive bacteria, including methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus faecalis, and activity against some gram-negative bacteria. Time-kill analysis showed that the mode of action of BB-3497 was primarily bacteriostatic. The mechanism of resistance was via mutations within the formyltransferase gene, as previously described for actinonin. While actinonin and its derivatives have not been used clinically because of their poor pharmacokinetic properties, BB-3497 was shown to be orally bioavailable. A single oral dose of BB-3497 given 1 h after intraperitoneal injection of S. aureus Smith or methicillin-resistant S. aureus protected mice from infection with median effective doses of 8 and 14 mg/kg of body weight, respectively. These data validate PDF as a novel target for the design of a new generation of antibacterial agents.

Abstract
Cutaneous B-cell lymphomas (CBCLs) are rare and are usually secondary to systemic nodal lymphoma. These lymphomas account for about 20% of all cutaneous lymphomas. Only recently has the existence of B-cell lymphoma presenting clinically in the skin without evidence of extracutaneous involvement been accepted as primary CBCL. The application of immunohistochemistry and molecular analysis has shown that some cases of cutaneous lymphoid hyperplasia and pseudolymphomas contain a monoclonal population of B cells and are therefore considered true lymphomas. The pathology and classification of this heterogeneous group of lymphoproliferative disorders is reviewed. The main entities comprise marginal zone lymphoma, lymphoplasmacytoid lymphoma (immunocytoma), follicular center cell lymphoma, mantle cell lymphoma, large cell lymphoma (immunoblastic and anaplastic), intravascular lymphomatosis, plasmacytoma, and lymphoblastic lymphoma.

Abstract
Numerous studies have implicated the pRB family of nuclear proteins in the control of cell cycle progression. Although over-expression experiments have revealed that each of these proteins, pRB, p107, and p130, can induce a G(1) cell cycle arrest, mouse knockouts demonstrated distinct developmental requirements for these proteins, as well as partial functional redundancy between family members. To study the mechanism by which the closely related pRB family proteins contribute to cell cycle progression, we generated 3T3 fibroblasts derived from embryos that lack one or more of these proteins (pRB(-/-), p107(-/-), p130(-/-), pRB(-/-)/p107(-/-), pRB(-/-)/p130(-/-), and p107(-/-)/p130(-/-)). By comparing the growth and cell cycle characteristics of these cells, we have observed clear differences in the manner in which they transit through the G(1) and S phases as well as exit from the cell cycle. Deletion of Rb, or more than one of the family members, results in a shortening of G(1) and a lengthening of S phase, as well as a reduction in growth factor requirements. In addition, the individual cell lines showed differential regulation of a subset of E2F-dependent gene promoters, as well as differences in cell cycle-dependent kinase activity. Taken together, these observations suggest that the closely related pRB family proteins affect cell cycle progression through distinct biochemical mechanisms and that their coordinated action may contribute to their diverse functions in various physiological settings.

Abstract
Cholangiocarcinoma is one of the most common malignancies of the biliary tree. Most cases are perihilar. Cholangiocarcinoma usually has an indolent, slowly progressive course and is associated with a high mortality rate. In this article, we discuss the management of perihilar cholangiocarcinoma by radiation therapy and chemotherapy in a case in which no recurrence was found on autopsy.

Abstract
We report a 54-year-old male, with a 5-year history of spreading asymptomatic generalized cutaneous telangiectases. The patient had no mucosal or nail involvement, no positive family history and no clinical evidence of systemic disease or bleeding diathesis. Histologically, the superficial small dermal blood vessels were dilated and showed thickened walls with hyaline perivascular material, staining as collagen. The vessel walls were PAS and colloidal iron stain positive, and immuno-histochemically lacked actin staining. Collagen IV, fibronectin and laminin antibodies showed the material deposited around the basement membrane zone. Ultrastructurally, the vessels were post-capillary venules (PCV) and showed marked collagen deposition around the basal lamina. There were many abnormally banded widely spaced fibres with 100-150 nm periodicity (Luse bodies), in addition to regular banded collagen. Pericytes were sparse and lacked intracytoplasmic filaments, and few veil or fibroblastic cells were seen embedded within the collagen. We believe this is a form of cutaneous microangiopathy not previously described, with distinct morphology and unique ultrastructural features. It may be due to a genetic defect with erroneous production of disorganized collagen in the cutaneous microvasculature. Dermatologists and Dermatopathologists should be aware of this unusual cutaneous vasculopathy.

Abstract
A case-control study was conducted to determine the modifiable risk factors associated with vancomycin-resistant Enterococcus (VRE) colonization during a hospital outbreak. Cephalosporin use was identified as the only independent risk factor (odds ratio, 13.8; 95% confidence interval, 2.5-76.3; P = .01). Nursing work-load intensity was not associated with VRE colonization in this study.

Abstract
Accidental patient falls are becoming a major cause of concern for hospitalized inpatients. It is well known that patients who fall once during their hospital stay are more likely to fall again and that fall rates tend to be higher in hospitalized elderly individuals. Concerned health care team personnel recognize that many accidental patient falls may be predicted and, thus, prevented. The best tool to predict falls has not been determined yet. The purpose of this study was to compare the abilities of the Morse Fall Scale (MFS), the Functional Reach (FR) test, and the nurses' clinical judgment in predicting those inpatients on a rehabilitation unit and a geriatric medical ward who were most likely to fall. A total of 98 patients were screened in a 3-month period, with each patient undergoing all three instruments the same day. The results showed that the two objective standardized tests (i.e., MFS, FR) were time consuming and often inconvenient and were no better at prediction than the clinical judgments made by the primary nurses.

Abstract
A review of the scientific literature on population monitoring studies (on non-accidentally exposed populations) frequently show that many of these studies using similarly exposed populations and the same laboratory techniques do not produce consistent results. To illustrate the problem, a brief review of studies using well validated techniques (chromosome aberrations and hprt gene mutation) to elucidate genotoxic effects of cigarette smoking is presented. Although many factors can contribute to the generation of discrepant results, two obvious factors are small sample sizes and inadequate experimental data. In addition, a new factor on genetic susceptibility should be considered in population studies whenever appropriate. The new factor is based on recent data showing the influence of polymorphic metabolizing genes on response to environmental mutagens towards biological effects and disease outcome. The common ones include the cytochrome P450 and the glutathione S-transferase genes. The inclusion of susceptibility factors in population monitoring may revolutionize the approach for health risk assessment and for environmental regulations.

Abstract
Recent studies demonstrate that 14-membered macrolides increase permeability and destruction of Pseudomonas biofilms. The effect of a macrolide antibiotic, erythromycin, on methicillin-resistant Staphylococcus aureus (MRSA) biofilm on Silastic catheter materials in comparison with two different quinolone antibiotics, sparfloxacin (SPFX) and a new quinolone, SYN 1193, was examined. Two different MRSA strains were grown in biofilm, using Mueller-Hinton broth with and without the addition of 10% pooled normal human serum (PNHS), in a modified Robbins device, at 37 degrees C for 24, 48, and 72 hours. Two different clinical MRSA strains were used and minimum bactericidal concentration (MBC) were determined at the time intervals mentioned. Three different dosages of each antibiotic were tested: 5.0, 20.0, and 50.0 micrograms/mL. In addition, a constant dosage of SPFX and SYN 1193, in combination with varying dosages of erythromycin, was tested under similar experimental conditions. SYN 1193 demonstrated the highest MBC in comparison to SPFX; addition of PNHS did not alter the effect of SYN 1193. However, erythromycin alone and in combination with SPFX and SYN 1193 had no effect on MBC. We conclude that (1) macrolide antibiotic erythromycin has poor MRSA biofilm permeability and killing in comparison to SPFX and SYN 1193, and (2) SYN 1193 had the highest MBC to MRSA biofilm.

Abstract
Captopril was effective in the long term reduction of serum sodium and aldosterone in normotensive rats, the addition of HCT produced a further decrease in serum sodium and was also useful in preventing hypokalemia produced by HCT. On the other hand, the concurrent therapy with Diclofenac attenuated the hypotensive effect of Captopril and HCT, it was observed that to combine Diclofenac with captopril was more beneficial as regards the metabolic parameters.

Abstract
A large proportion of Ascobolus immersus transformants are highly unstable in crosses: the phenotype conferred by the transgene is not transmitted to the progeny, irrespective of the endogenous or foreign origin of the transgene. They all have integrated multiple transgene copies, clustered at a single chromosomal site or at tightly-linked sites. Clustered non-homologous integrations are always rearranged. Yet they never escape the "methylation induced premeiotically" (MIP) process. This always results in gene silencing, even when the transgene is partially repeated, accounting for the high instability of these transformants.

Abstract
The effects of the non-selective beta-blocker propranolol (CAS 525-66-6) and the cardioselective drug atenolol (CAS 29122-68-7) on serum glucose, insulin levels and some serum lipid components, were compared in normal and diabetic rats receiving glibenclamide. The two beta-blockers, when administered concurrently with glibenclamide in normal rats, exerted a significant hypoglycemic effect (p < 0.01), while in diabetic rats the two drugs caused a more significant decrease (p < 0.001 and p < 0.01, resp.). Serum insulin levels were mainly unaffected by the two beta-blockers. Propranolol was found to exhibit a hypolipidemic effect in diabetic rats when administered alone or in combination with glibenclamide. In comparison atenolol, when used alone, exerted a significant increase in triglycerides and total lipid levels (p < 0.05) in normal rats. This effect was masked when atenolol was administered concurrently with glibenclamide, but a hypercholesterolemic effect (p < 0.01) was noticed. Paradoxically in diabetic rats, atenolol caused a significant decrease (p < 0.05) in triglycerides level, while its combined use with glibenclamide showed no effect.

Abstract
Extraosseous osteogenic sarcomas are unusual tumors that are seldom diagnosed. Although primary renal osteogenic sarcoma has been reported, and is described in the Armed Forces Institute of Pathology fascicle, most clinicians are unaware of its existence. We describe a patient with this disease to remind clinicians of this tumor, its presentation and rapid evolution.

Abstract
Resonance Raman electronic absorption and circular dichroism spectra and pH titration curves are reported for the trianionic ferric complexes of enterobactin, catechol, and N-methyl-2,3-dihydroxybenzamide (MDHB). The spectral signatures of the enterobactin and MDHB complexes are virtually identical and differ from those of the catechol complex in ways that reflect the influence of the amide group on the electronic structure. Excitation in either the visible charge-transfer bands or the near-ultraviolet pi-pi* bands enhances Raman bands associated with benzene ring modes, although the relative enhancements differ markedly in the two regions. The data stronly support a structural model in which iron is bound exclusively to the phenolate oxygen atoms in all three complexes.
