Abstract
OBJECTIVES Factors associated with an individual's awareness of vulnerability can be modified by the infrastructure of a city. These factors may impact disaster preparedness among local populations in an infrastructure-resilient city, which further influences the health risks of various population subgroups. STUDY DESIGN This was a population-based study. METHODS Four population subgroups, which have previously been reported to be related to awareness of vulnerability (i.e. past experiences, sociodemographic deprivation, poor housing conditions and family medical needs), were analysed for their impacts on disaster preparedness. Validated population-based phone interviews (n = 856) were conducted in Hong Kong. Three types of disaster preparedness were studied: (1) physical preparedness; (2) social preparedness; and (3) education preparedness. RESULTS Previous experience of social hazards, accidental hazards and epidemics increased disaster preparedness among the local population. Specifically, experiences of accidental hazards and social hazards were positively associated with physical preparedness (odds ratios 1.626, 95% confidence interval [95% CI] 1.215, 2.172) and 1.501 [95% CI 1.114, 2.024], respectively). However, experiences of natural hazards did not increase preparedness, even in Hong Kong, which is a city with high 'disaster resilience' because of its well-developed infrastructure. Moreover, individuals with a low educational level or low income had lower education preparedness, unmarried individuals had lower social preparedness, and poor housing conditions of non-private-housing households had negative associations with education preparedness. These findings partially align with local disaster responses to the 2018 Typhoon Mangkhut, the 2019 social unrest and the 2020 COVID-19 pandemic, all of which were observed after the 2018 survey reported in this study. CONCLUSIONS Social and environmental interventions should be targeted to marginalised subpopulations through location-based community strategies to encourage increased environmental knowledge and participation in disaster preparedness activities.

Abstract
ROS1 is a pivotal transmembrane receptor protein tyrosine kinase which regulates several cellular processes like apoptosis, survival, differentiation, proliferation, cell migration, and transformation. There is increasing evidence supporting that ROS1 plays an important role in different malignancies including glioblastoma, colorectal cancer, gastric adenocarcinoma, inflammatory myofibroblastic tumor, ovarian cancer, angiosarcoma, and non small cell lung cancer; thus, ROS1 has become a potential drug discovery target. ROS1 shares about 49% sequence homology with ALK primary structure; therefore, wide range of ALK kinase inhibitors have shown in vitro inhibitory activity against ROS1 kinase. After Crizotinib approval by FDA for the management of ALK-rearranged lung cancer, ROS1-positive tumors have been focused. Although significant advancements have been achieved in understanding ROS1 function and its signaling pathways plus recent discovery of small molecules modulating ROS1 protein, a vital need of medicinal chemistry efforts is still required to produce selective and potent ROS1 inhibitors as an important therapeutic strategy for different human malignancies. This review focuses on the current knowledge about different scaffolds targeting ROS1 rearrangements, methods to synthesis, and some biological data about the most potent compounds that have delivered various scaffold structures.

Abstract
To determine the potential for Tilletia indica, cause of Karnal bunt of wheat, to survive and become established in new areas, a teliospore longevity study was initiated in Kansas, Maryland, Georgia, and Arizona. Soil from each location was infested with T. indica teliospores and placed in polyester mesh bags. The bags were placed within soil from the same location within polyvinyl chloride pipes. Pipes were buried in the respective plots such that the bags were at 5-, 10-, and 25-cm depths. Each pipe was open at the ends to allow interaction with the outside environment, however fitted with screens preventing possibility of teliospore escape. In the Karnal bunt-quarantine area of Arizona, bags of infested soil also were placed outside the pipes. Teliospore-infested soil from each location was maintained dry in a laboratory. During the first 2 years, viability declined more rapidly in pipes than outside pipes, and more rapidly in fields in Kansas and Maryland than in Georgia or Arizona. After 2 years, viability declined nearly equally. In the laboratory over 3 years, viability decreased significantly more rapidly in dry soil from Kansas or Maryland than in dry soil from Georgia or Arizona, while pure teliospores remained unchanged. We hypothesized that soils, irrespective of weather, affect teliospore longevity.

Abstract
Isopenicillin N synthase (IPNS) catalyses a key step in the penicillin and cephalosporin biosynthetic pathway which involves the oxidative cyclisation of the acyclic peptide delta-(L-alpha-aminoadipyl)-L-cysteinyl-D-valine (ACV) to isopenicillin N. Based on crystallographic evidence from the Aspergillus nidulans IPNS crystal structure complexed with the substrate ACV (Roach et al. (1997) Nature 387, 827-830), we were able to provide mutational evidence for the critical involvement of the conserved R-X-S motif in ACV binding in IPNS. The crystal structure further implicated arginine-87 in the binding of the aminoadipyl portion of ACV. Thus, in this study, the site-directed mutagenesis of the corresponding arginine-89 in Cephalosporium acremonium IPNS (cIPNS) was performed to ascertain its role in cIPNS. Alteration of arginine-89 to five amino acids from different amino acid groups, namely lysine, serine, alanine, aspartate and leucine, was performed and no activity was detected in all the mutants obtained when enzyme bioassays were performed. Furthermore, the solubility of the mutants was considerably lower than the wild-type cIPNS after expression at 37 degrees C, but could be recovered when the expression temperature was lowered to 25 degrees C. This suggests that arginine-89 could be critical for the activity of cIPNS due to its involvement in ACV binding and the solubility of wild-type enzyme.

Abstract
BACKGROUND Perennial rhinitis is a common condition that affects up to 10% to 20% of the population. Multiple agents are frequently administered since no single agent provides complete relief. Studies assessing the benefit/risk of combined therapy are important especially for newly approved agents such as ipratropium bromide nasal spray 0.03%, a topical anticholinergic agent, approved specifically for the treatment of rhinorrhea in allergic and non-allergic perennial rhinitis. OBJECTIVE To compare the efficacy and safety of the combined use of ipratropium bromide nasal spray 0.03% (42 microg per nostril tid) and beclomethasone dipropionate nasal spray (84 microg per nostril bid) against that of either active agent alone for the treatment of rhinorrhea. DESIGN Multicenter, 6-week, double-blind, randomized active- and placebo-controlled, parallel trial. SETTING Allergist and general practitioner clinical practices. PATIENTS Five hundred thirty-three patients with perennial rhinitis (279 allergic and 274 non-allergic), 8 to 75 years of age, who had at least a mild degree of severity of rhinorrhea for a minimum of 2 hours per day during the 1 week screening period as well as congestion or sneezing also of at least mild severity. INTERVENTION Either (1) ipratropium bromide nasal spray 0.03% (42 microg per nostril tid) plus beclomethasone dipropionate nasal spray (84 microg per nostril bid), (2) ipratropium bromide nasal spray 0.03% (42 microg per nostril tid) alone, (3) beclomethasone dipropionate nasal spray (84 microg per nostril bid) alone, or (4) vehicle [matching placebo nasal spray for the ipratropium bromide (2 sprays per nostril tid)] or beclomethasone dipropionate (2 sprays per nostril bid). MAIN OUTCOME MEASURE Severity and duration of rhinorrhea, and patient and physician global assessment of control of rhinorrhea. RESULTS Ipratropium bromide nasal spray plus beclomethasone nasal spray was more effective than either active agent alone or vehicle in reducing the average severity and duration of rhinorrhea during 4 weeks of treatment. The advantage of ipratropium bromide plus beclomethasone nasal spray was evident by the first day of combined treatment and continued throughout the 2-week treatment period. Ipratropium bromide nasal spray had a faster onset of action during the first week of treatment and reduced the duration of rhinorrhea more than beclomethasone. Beclomethasone nasal spray was more effective in reducing the severity of congestion and sneezing than ipratropium. In patients who had not responded well to a nasal steroid prior to participation in the study based on a questionnaire administered at screening, ipratropium bromide was as effective in the steroid non-responders as steroid responders, whereas beclomethasone was more effective in steroid responders. Combined active therapy was well tolerated with no increase in adverse events over that seen previously with ipratropium bromide or beclomethasone nasal spray alone. CONCLUSIONS The combined use of ipratropium bromide nasal spray with beclomethasone dipropionate nasal spray is more effective than either active agent for the treatment of rhinorrhea, and does not result in a potentiation of adverse drug reactions. Ipratropium bromide nasal spray 0.03% alone should be considered in patients for whom rhinorrhea is the primary symptom, and its use in combination with a nasal steroid should be considered in patients where rhinorrhea is one of the predominant symptoms, or in patients with rhinorrhea not fully responsive to other therapy.

Abstract
In order to evaluate the role of polymorphonuclear leukocytes (PMNs) in acute otitis media (AOM), levels of leukotriene B4 (LTB4), a potent inflammatory product of PMNs, and interleukin-8 (IL-8), a PMN chemotactic cytokine, were measured in 271 middle ear fluid (MEF) samples from 106 children with AOM. Forty-two percent of the patients had evidence of respiratory viral infection. At the time of diagnosis, levels of both LTB4 and IL-8 were higher in the MEFs from patients with AOM associated with bacterial or bacterial and viral infection than those MEFs containing no pathogen (p < .05). Antibiotic treatment was not associated with a significant change in levels of LTB4 or IL-8 in the MEFs obtained 2 to 5 days into treatment, compared to those obtained at diagnosis. Bacteriologic failure after 2 to 5 days of treatment was associated with high LTB4 levels in the initial MEFs (p = .05). Recurrence of AOM within 1 month was associated with high IL-8 levels in the initial MEF (p = .04). Our findings suggest that LTB4 and IL-8 are produced during acute infection of the middle ear, and these PMN-related inflammatory substances may play an important role in delaying recovery or in recurrence of AOM. Effective treatment of AOM may require eradication of bacteria by antibiotics, as well as pharmacologic agents that modulate PMN functions.

Abstract
Chemokines are cytokines that induce chemotaxis of inflammatory cells. We studied the presence of chemokines in bronchoalveolar lavage fluid (BALF) obtained from nine allergic asthmatic patients and six nonsmoking normal individuals. The cells were pelleted, and ribonucleic acid (RNA) was extracted by using RNAzol B. BALF was assayed for monocyte chemoattractant protein-1 (MCP-1), regulated upon activation in normal T cells, expressed, probably secreted (RANTES), macrophage inflammatory protein-1alpha (MIP-1alpha) and interleukin-8 (IL-8) by enzyme-linked immunosorbent assay (ELISA). The levels of MCP-1, RANTES, and MIP-1alpha were significantly higher in the asthma patients than in the control subjects (p<0.04). The concentrations of RANTES and MCP-1 correlated with the lymphocyte count in the BAL specimens (r = 0.61 and 0.68, respectively). BALF showed eosinophil chemotactic activity in vitro that was blocked by anti-RANTES and anti-MCP-3 antibodies. The total cellular RNA was reverse-transcribed and the complementary deoxyribonucleic acid (cDNA) was amplified with the polymerase chain reaction (PCR) for MCP-1, MCP-3, RANTES, MIP-1alpha, IL-8, and beta-actin. We found that messenger ribonucleic acids (mRNAs) for MCP-1, MCP-3, RANTES, MIP-1alpha, and IL-8 were produced by BAL cells from most asthmatic and normal subjects. We conclude that chemokines are produced in the airways, and that an increased recovery of MCP-1, RANTES, and MIP-1alpha is observed in allergic asthmatic patients.

Abstract
Non-self class I histocompatibility Ag can act as strong alloantigens and be recognized as distinct targets by CTL. To study the possibility of using allograft rejection to generate tumor-specific immunity, we have introduced an allogeneic class I histocompatibility gene, the H-2Kb gene, into a k haplotype tumor, K36.16, by DNA-mediated gene transfer. The K36.16 tumor grows readily and does not confer protective immunity in AKR mice. A total of 37 H-2Kb-transfected K36.16 clones (Kb/K36.16) was isolated and studied individually. The Kb/K36.16 clones were found to differ significantly in the amount of the exogenous H-2Kb antigens expressed on their cell surface. Moreover, as a result of the transfection, the level of expression of the endogenous H-2Dk Ag was also altered when compared to that of the parental K36.16 tumor cells. All the Kb/K36.16 clones that were positive for the H-2Kb Ag were rejected by the semisyngeneic AKR mice. Moreover, some of these Kb/K36.16 clones were also rejected by syngeneic (AKR x C57BL/10)F1 mice. In consequence of immunization with the Kb/K36.16 clones, the AKR and F1 mice were able to survive a subsequent challenge of the wild-type, unmodified, parental K36.16 tumor cells. More importantly, some of these Kb/K36.16 clones demonstrated an active and specific immunotherapeutic effect, and they were able to eradicate the growth of the parental K36.16 tumor cells in AKR mice. This observation therefore reinforces the feasibility of using DNA-mediated gene transfer as a molecular approach to abrogate tumor growth.

Abstract
In 19 patients treated with carbon-fiber ligament augmentation for the anterior cruciate ligament, the clinical findings were compared via MRI. Visualization of the intra- and extra-articular portion of the graft was possible in 84%. The integrity of the ligaments was be shown in an equal percentage. Thus, MRI is a useful diagnostic tool for non-invasive imaging for repeated follow-ups in patients with carbon-fiber ligament augmentation.
