Abstract
BACKGROUND Research on the longer-term sequelae of COVID-19 in patients with asthma is limited. OBJECTIVE To assess the frequency and severity of long-term symptoms of COVID-19 in the population of asthma patients. METHODS A systematic review of the published literature was conducted in accordance with the recommendations of the PRISMA statement. EMBASE, MEDLINE/PubMed, Web of Science, CINAHL, and Scopus Scholar were searched for terms related to asthma and post or long COVID-19, and for systematic reviews related to specific questions within our review, up to June 2022. RESULTS Data from 9 references publications included in the review were extracted. A total of 1466 adult asthmatic patients with COVID-19 infection were described in all the publications mentioned above. Of the long-term symptoms reported after COVID-19, patients indicated: lower respiratory symptoms, fatigue, cognitive symptoms, psychological problems, and other such as skin rashes, gastrointestinal disorders, tachycardia, palpitations, ocular disorders, ageusia/hypogeusia, anosmia/hyposmia, and poor sleep quality. These symptoms in similar intensity were observed in the comparison groups without a diagnosis of asthma. CONCLUSIONS The published data neither confirm nor deny that long-term COVID-19 symptoms in patients with asthma diagnosis are different in strength and frequency from patients without asthma diagnosis. To indicate associations between asthma and COVID-19 infection and severity, as well as the frequency of long-term symptoms of COVID-19, more longitudinal research is needed in chronic asthma patients with different phenotypes, intensity of treatment, and degree of asthma control.

Abstract
Introduction The treatment of Hymenoptera venom allergy (HVA) is based among others on the proper identification of the culprit insect. Aim To assess the accuracy in identifying stinging insects by children with HVA and their parents. Material and methods Participants were recruited from a paediatric medical centre. The data on their demographics, sting history and ability of insect identification (based on pictures) were obtained using a questionnaire. The study sample consisted of 102 children with HVA and their parents as well as 98 children without HVA and their parents. Results The rates of subjects correctly identifying insects in the groups were 91.2%, 92.5%, 78.8%, 82.4%, respectively. When compared to children with HVA, those without HVA were less likely to correctly identify the bee, bumblebee and hoverfly. In this group, the correct identification of the wasp was more common among children living in the countryside. The correct identification of the bee and bumblebee by children without HVA was more common among children living in the city. Conclusions Some children with HVA and their parents cannot correctly identify stinging insects despite previous life-threatening allergic reactions. The ability to identify stinging insects may depend on the HVA diagnosis and place of residence.

Abstract
Abstract
Background
Rotational atherectomy is a highly effective technique to facilitate percutaneous intervention on highly calcified coronary lesions. In some cases, despite numerous passages of the burr, successful crossing of the lesion is impossible. Empirical evidence shows that burr replacement is usually successful, therefore suggesting possible mechanical wear of the tool, however this hypothesis was never tested.
Aims
The aim of this study was to asses the possible mechanisms of mechanical burr degradation after rotational atherectomy in scanning electron microscope.
Methods
Burrs after the procedure were cleaned and examined in the scanning electron microscope. In order to facilitate the quantification of possible changes burrs were divided into 7 areas in which the analysis was carried out separately according to preestablished protocol. There were several methods applied to determine the degree of tool wear. The first one was to count the number of pull-outs of the diamond coating. Secondly we used image analysis to determine the dark phase share in the particular areas, which corresponds to the amount of the diamond phase. Finally we compared new burrs with used ones to asses weather any signs of mechanical wear of the tool were visible. Examples of burr division and applied methods are presented in Figure 1.
Results
We included 13 burrs into our analysis, 2 new ones and 11 that were used for various amount of time during the procedure (24 to 540 seconds, mean 132 seconds). Except for one area there were no differences between new and used burrs in regard of studied parameters. Results are presented in Table 1.
Conclusions
Our study showed no signs of mechanical wear of rotablation burrs during the procedure. Further studies are needed to evaluate other possible causes of burr's loss of grinding properties such as covering by biological particles etc.

Abstract
BACKGROUND External inflammatory root resorption (EIRR) is a frequent complication of traumatic dental injuries (TDI). The aim of this cohort study was to identify novel non-invasive markers of post-traumatic EIRR by assessing the changes in the pulp's blood flow and the composition of gingival sulcus fluid (GCF) in children after dental trauma. MATERIAL AND METHODS Thirty-two children were enrolled and assessed within 48 h of a TDI to their permanent incisors and during an additional three visits over a 6-months follow up period. During each visit, a radiograph and laser Doppler flow (LDF) measurements of the pulp blood flow were performed on the injured tooth, and the GCF was sampled. The permanent first molar tooth of the same subject served as a control for the LDF measurements and the GCF sampling. Concentrations of IL-1α in the GCF were measured using enzyme-linked immunosorbent assays. Radiographs were used to confirm EIRR. RESULTS EIRR occurred in fourteen (43.8%) teeth in 32 patients. The teeth with EIRR showed diminished LDF readings when compared with controls at all visits. The LDF readings of the injured teeth continued to decrease at follow up visits. In the EIRR group, levels of IL-1α in the GCF of teeth with EIRR were increased and significantly higher than those of the control teeth at the visit when EIRR was diagnosed. The IL-1α levels were significantly higher in the EIRR group when compared to the injured teeth of patients without EIRR at the last follow-up visit. CONCLUSIONS The occurrence of EIRR after mechanical trauma of permanent teeth with complete root development is accompanied by a significant reduction in the blood flow of the tooth's pulp. It is accompanied by an increase in concentrations of IL-1α in the GCF of EIRR affected teeth. The results of this pilot study identified the use of IL-1α in GCF and LDF as non-invasive markers of EIRR.

Abstract
Esophageal variceal bleeding is one of the most severe complications that may occur during pregnancy in patients with liver cirrhosis. It may result in death of the mother and the fetus. Therefore, screening endoscopy should be performed both before the conception and in the second trimester. Endoscopic band ligation is a method of choice in case of variceal bleeding. Close cooperation of hepatologist, obstetrician-gynecologist and endoscopist is recommended in order to provide maximum care and increase the chances of successful delivery. We present a case of 28-years-old primigravida, at 27 weeks pregnant with esophageal varices and liver cirrhosis.

Abstract
INTRODUCTION Much emphasis is being placed on the role of music therapy as an easy-to-use, noninvasive and relatively cheap method of asthma treatment. The objective of this interventional double-blinded randomized controlled trial was to assess whether music therapy, as a complementary modality to pulmonary rehabilitation, can help to improve respiratory drive, asthma control and quality of life in patients with asthma exacerbation. METHODS Hospitalized patients with asthma exacerbation enrolled in the study were randomly assigned to experimental (music therapy) or control (popular science program) group. Both groups during hospitalization received standard pharmacotherapy accompanied by respiratory physiotherapy. Respiratory drive, asthma control, quality of life and serum cortisol in all participants were assessed at the beginning and at the end of their hospitalizations. RESULTS The experimental group consisted of 39 asthmatics and 34 subjects with asthma were assigned to the control group. During the hospitalization, the levels of the inspiratory occlusion pressure for the first 0.1 s of inspiration (P0.1) decreased (p = 0.004) and the maximum P0.1 increased (p = 0.041) only in the experimental group. The serum cortisol level decreased in both groups (p = 0.001). The changes in asthma control and quality of life did not reach significant levels in either subject group. CONCLUSION Passive music therapy and its effects on the mental state of patients seem to improve the efficiency of the respiratory system. The results of this experimental study demonstrate that a complementary music therapy has beneficial effects on the treatment of asthma exacerbations in adults.

Abstract
The comorbidity of peripheral arterial disease (PAD) and chronic obstructive pulmonary disease (COPD) is obvious from a clinical point of view, especially as smoking is an important risk factor for both. Another factor connecting these two clinical conditions is chronic inflammation, which plays a crucial role in their pathophysiology. The aim of this study was to present the prevalence of COPD in patients with PAD, as well as the prevalence of PAD in COPD patients confirmed in all patients by two reliable methods: spirometry and ankle-brachial index (ABI), respectively. The MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews were searched to identify the potentially eligible publications from the previous 10 years. The published characteristics of different PAD and COPD populations were analyzed. A database search identified 894 records. Reliable criteria of both COPD and PAD diagnosis were used only in seven publications. The prevalence of PAD among patients with COPD ranged from 8.5 to 81.4%. The severity of the disease and the exclusion of nonsmokers or symptomatic patients from the analyses were important factors affecting this parameter. The prevalence of COPD in patients with PAD was measured reliably only in one study and assessed as 27.2%. The comorbidity of COPD and PAD is a relatively common occurrence. There are very few publications addressing this issue based on reliable diagnostic criteria, especially in the field of PAD. In the case of COPD and PAD patients, spirometry and ABI measurements are worth considering as noninvasive screening tests for COPD and PAD, respectively.

Abstract
Background: Inspiratory muscle training (IMT) is a non-pharmacological, non-invasive therapeutic method that can improve the quality of life in patients with obstructive lung diseases. The effectiveness of IMT may depends on the type of the device used in the training and the parameters of the training programme.
Objectives: The aim of the review was to present different techniques and protocols of IMT used in patients with obstructive lung diseases.
Methods: The MEDLINE and EMBASE were searched to identify the potentially eligible publications from the previous 5 years. The various protocols of IMT used in different studies were analysed and described in detail.
Results: A database search identified 333 records, of which 22 were included into the final analysis. All of the finally analysed studies were conducted in patients with chronic obstructive pulmonary disease (COPD). The protocols of IMT used in the studies differed in the type of the device used, the duration of the training programme, the number and the duration of training sessions, the initial load, and the rate at which the load was changed during the training.
Conclusions: IMT is used mainly in studies on patients with COPD and not with asthma. There is no one approved training programme for IMT. The most predominant type of IMT is a training with threshold loading. The most frequently used devices for IMT are POWERbreath and Threshold IMT. The protocols of IMT used in the studies are very diverse.

Abstract
BACKGROUND Isoprostanes are bioactive compounds formed by non-enzymatic oxidation of polyunsaturated fatty acids, mostly arachidonic, and markers of free radical generation during inflammation. In aspirin exacerbated respiratory disease (AERD), asthmatic symptoms are precipitated by ingestion of non-steroid anti-inflammatory drugs capable for pharmacologic inhibition of cyclooxygenase-1 isoenzyme. We investigated whether aspirin-provoked bronchoconstriction is accompanied by changes of isoprostanes in exhaled breath condensate (EBC). METHODS EBC was collected from 28 AERD subjects and 25 aspirin-tolerant asthmatics before and after inhalatory aspirin challenge. Concentrations of 8-iso-PGF2α, 8-iso-PGE2, and prostaglandin E2 were measured using gas chromatography/mass spectrometry. Leukotriene E4 was measured by immunoassay in urine samples collected before and after the challenge. RESULTS Before the challenge, exhaled 8-iso-PGF2α, 8-iso-PGE2, and PGE2 levels did not differ between the study groups. 8-iso-PGE2 level increased in AERD group only (p=0.014) as a result of the aspirin challenge. Urinary LTE4 was elevated in AERD, both in baseline and post-challenge samples. Post-challenge airways 8-iso-PGE2 correlated positively with urinary LTE4 level (p=0.046), whereas it correlated negatively with the provocative dose of aspirin (p=0.027). CONCLUSION A significant increase of exhaled 8-iso-PGE2 after inhalatory challenge with aspirin was selective and not present for the other isoprostane measured. This is a novel finding in AERD, suggesting that inhibition of cyclooxygenase may elicit 8-iso-PGE2 production in a specific mechanism, contributing to bronchoconstriction and systemic overproduction of cysteinyl leukotrienes.

Abstract
The article concerns the problem of patients with aggressive behaviour and the most common methods for estimating the potential risk of appearance of such behaviour. The problem mentioned above is related in particular to psychiatric facilities, but it is also present in medical facilities of general type. The importance of this problem is underlined by epidemiological data. The article includes a description of two widely used instruments, namely the HCR 20 (The Historical Clinical and Risk Management Scale 20) and the PCL-R (The Hare Psychopathy Checklist-Revised) but also the actuarial instruments the VRAG (The Violence Risk Assessment Guide) and the SORAG (The Sex Offender Risk Assessment Guide). The article also presents an instrument for the dynamic assessment, the START (The Short-Term Assessment of Risk and Treatability). The usefulness and limitations of these instruments are developed. Some personality disorders may predispose an individual to commit acts of aggression or violence. This topic is also developed in the text. The article focuses on the rationale for the usefulness of regular training of risk assessment for staff, which increases security and helps to plan the care correctly.

Abstract
BACKGROUND Eicosanoids, important signaling and inflammatory molecules, are present in exhaled breath condensate (EBC) in very low concentrations, requiring highly sensitive analytic methods for their quantification. OBJECTIVE We sought to assess a vast platform of eicosanoids in different asthma phenotypes, including aspirin-intolerant asthma, by means of a recently developed analytic approach based on mass spectrometry. METHODS EBC from 115 adult asthmatic subjects (62 with aspirin intolerance) and 38 healthy control subjects were assessed quantitatively for 19 eicosanoids by using complementary HPLC, gas chromatography-mass spectrometry, or both. Palmitic acid concentrations were used as a marker for dilution of condensate samples. RESULTS Asthma was characterized by an increase in arachidonate lipoxygenase products and cysteinyl leukotrienes. The COX pathway was also significantly upregulated in asthmatic subjects. Subjects with aspirin-intolerant asthma were distinguished by a sharp increase in the level of prostaglandin D(2) and E(2) metabolites; their 5- and 15-hydroxyeicosateraenoic acid levels were also higher than in aspirin-tolerant subjects. A classical discriminant analysis permitted us to classify correctly 99% of asthmatic subjects within the study population; the specificity of the analysis was 97%. The eicosanoid profiling allowed for 92% correct classification of aspirin-intolerant subjects. CONCLUSIONS The highly sensitive eicosanoid profiling in EBC makes it possible to detect alterations in asthma, especially in its distinct phenotype characterized by hypersensitivity to aspirin and other nonsteroidal anti-inflammatory drugs. This permits us to discriminate asthmatic subjects from healthy subjects, as well as to distinguish the 2 asthma phenotypes based on the presence or absence of aspirin hypersensitivity.

Abstract
BACKGROUND Exhaled breath condensate collection is a non-invasive method of sampling the respiratory tract that can be repeated several times in a wide range of clinical settings. Quantitation of non-volatile compounds in the condensate requires highly sensitive analytical methods, e.g. mass spectrometry. OBJECTIVE To validate cross-platform measurements of eicosanoids using high performance liquid chromatography or gas chromatography coupled with mass spectrometry in exhaled breath condensate sampled from 58 healthy individuals. METHODS Twenty different eicosanoid compounds, representing major arachidonic acid lipoxygenation and cyclooxygenation pathways were measured using a stable isotope dilution method. We applied a free palmitic acid concentration as a surrogate marker for the condensate dilution factor. RESULTS Eicosanoids concentrations in the condensates were consistent with their content in other biological fluids. Prostaglandin E(2) was the most abundant mediator, represented by its stable metabolite tetranor-PGEM. Prostaglandin D(2) products were at low concentration, while hydroxyacids derived from lipoxygenation were abundant. 5-HETE was elevated in current tobacco smokers. Leukotriene B(4) has the highest concentration of all 5-LO products. 15-LO analogues of cysteinyl leukotrienes-eoxins were detectable and metabolized to eoxin E(4). Two main vascular prostanoids: prostacyclin and thromboxane B(2) were present as metabolites. A marker for non-enzymatic lipid peroxidation, 8-iso-PGF(2alpha) isoprostane was increased in smokers. CONCLUSION Presented targeted lipidomics analysis of exhaled breath condensate in healthy subjects justifies its application to investigation of inflammatory lung diseases. Measurements of non-volatile mediators of inflammation in the condensates might characterize disease-specific pathological mechanisms and responses to treatment.

Abstract
Actinomycosis is a rare infectious inflammatory disease caused by the bacteria of the Actinomyces species. Infection occurs following damage to the skin or mucous membrane. This report presents a case of a 50-year-old female patient with subfebrile temperature, weight loss and pain, who used to have an intrauterine device. Masses suggestive of an advanced cancer were detected in her pelvis and abdominal cavity. A diagnosis of actinomycosis was made after histopathological examination of the tissue sample.

Abstract
Concentration of abundant elements e.g. calcium as well as of elements present in trace amount e.g. zinc in mandibles of 7, 14 an 28 day old newborn rats were determined by X-ray fluorescence analysis. The measurements were carried out by using a measurement system containing X-ray tube ECLIPSE-III and X-ray and gamma ray detector XR-100T-CdTe (Amptek Inc.). Concentration of calcium and zinc depended on the region of interest on the rat's mandible due to mineralization degree conditioned by its function. Increasing age produced a remarkable increase in Ca content in contrast to Zn content in the bone tissue obtained from 7, 14 and 28 day old newborn rats. The calculated Zn/Ca concentration ratio was the biggest for 7 day old newborns and successively decreased with age indicating the important role of zinc at the beginning of bone ontogenesis.

Abstract
Inhaled corticosteroid therapy has proven efficacy for asthmatics, but the benefit for patients with chronic obstructive pulmonary disease (COPD) is less well supported. We hypothesized that withdrawal of inhaled steroids in elderly patients with severe irreversible airway obstruction would not lead to a deterioration in respiratory function. We designed a prospective, double-blind, randomized, placebo-controlled, crossover study to follow spirometry, quality of life questionnaire, six-minute (6-min) walk test, and sputum markers of inflammation during a 6-wk placebo treatment period and a 6-wk treatment period with beclomethasone dipropionate (BDP), 336 microg/d. There were 24 men receiving BDP who entered the study; 15 completed the study. Their mean age was 66.9 +/- 1.9 yr, and mean FEV(1) was 1.61 +/- 0.1 L (47% of predicted). There was a significant decrease in the mean FEV(1 )while using the placebo inhaler (1.70 L versus 1.60 L, baseline versus placebo: 95% CI, 0.002 to 0.195; p < 0.05). There was a decrease in the mean percentage change in FEV(1) for the study subjects during the placebo treatment period as compared with the BDP treatment period (-6.28 versus 5.03%, placebo versus BDP: 95% CI, -23.38 to 0.76; p = 0.06). Six-minute walk test results and sputum analysis for cell count and differential were not significantly different during placebo and BDP treatment periods. Borg scale assessment of dyspnea after exercise was increased while using the placebo inhaler as compared with baseline, and decreased during the BDP treatment period. Chronic Respiratory Disease Questionnaire (CRQ) scores revealed no significant difference between placebo and BDP. This study has demonstrated that in elderly patients with severe irreversible airway obstruction, withdrawal of inhaled corticosteroid therapy leads to a deterioration in ventilatory function and increased exercise-induced dyspnea.

Abstract
Reactive cationic and anionic liposomes have been prepared from mixtures of dimyristoylphosphatidylcholine (DMPC) and cholesterol incorporating dimethyldioctadecylammonium bromide and DMPC incorporating phosphatidylinositol, respectively. The liposomes were prepared by the vesicle extrusion technique and had the enzymes glucose oxidase (GO) encapsulated in combination with horseradish peroxidase (HRP) or lactoperoxidase (LPO). The generation of hydrogen peroxide from the liposomes in response to externally added D-glucose substrate was monitored using a Rank electrode system polarised to +650 mV, relative to a standard silver-silver chloride electrode. The effects of encapsulated enzyme concentration, enzyme combinations (GO+HRP, GO+LPO), substrate concentration, electron donor and temperature on the production of hydrogen peroxide have been investigated. The electrode signal (peroxide production) was found to increase linearly with GO incorporation, was reduced on addition of HRP and an electron donor (o-dianisidine) and showed a maximum at the lipid chain-melting temperature from the anionic liposomes containing no cholesterol. To aid interpretation of the results, the permeability of the non-reactive substrate (methyl glucoside) across the bilayer membranes was measured. It was found that the encapsulation of the enzymes effected the permeability coefficients of methyl glucoside, increasing them in the case of anionic liposomes and decreasing them in the case of cationic liposomes. These observations are discussed in terms of enzyme bilayer interactions.

Abstract
Liposomes have been prepared from dipalmitoylphosphatidylcholine (DPPC) incorporating the cationic lipids stearylamine (SA), dimethyldioctadecylammonium bromide (DDAB) and dimethylaminoethane carbamoyl cholesterol (DCchol) and the anionic lipids dipalmitoylphosphatidylglycerol (DPPG) and phosphatidylinositol (PI). Their adsorption to biofilms of skin-associated bacteria (Staphylococcus epidermidis and Proteus vulgaris) and oral bacteria (Streptococcus mutans and sanguis) has been investigated as a function of mole % cationic and anionic lipid. Targeting (adsorption) was most effective for the systems DPPC-chol-SA, DPPC-DPPG and DPPC-PI liposomes to S. epidermidis. The effect of extracellular mucopolysaccharide on targeting was investigated for S. epidermidis biofilms. It was found that targeting increased with the level of extracellular mucopolysaccharide for all liposome compositions studied. The delivery of the oil-soluble bactericide Triclosan and the water soluble bactericide chlorhexidine was studied for a number of liposomal compositions. Superior delivery of both bactericides relative to the free bactericide occurred for DPPC-chol-SA liposomes and for Triclosan delivery by DPPC-DPPG and DPPC-PI liposomes targeted to S. epidermidis at low bactericide concentrations. DPPC-chol-SA liposomes were also effective for delivery of Triclosan to S. sanguis biofilms. Double labelling experiments using [14C]-chlorhexidine and [3H]-DPPC suggested that there was exchange between adsorbed liposomes which had delivered bactericide to the biofilm and those in the bulk solution implying a diffusion mechanism for bactericide delivery.

Abstract
Liposomes were prepared from phospholipid mixtures of dipalmitoylphosphatidylcholine (DPPC) and phosphatidylinositol (PI), encapsulating the enzymes glucose oxidase (GO) and GO in combination with horse radish peroxidase (HRP) by both extrusion (VET) and reverse-phase evaporation (REV). The optimum level of PI in DPPC/PI liposomes for targeting to biofilms of the oral bacterium Streptococcus gordonii has been established. The liposomes were characterised in terms of the content and activity of the encapsulated enzymes. The antibacterial activity of these 'reactive' liposomes arising from hydrogen peroxide and oxyacids in the presence of the substrates glucose and iodide ions, after targeting to the biofilms, were measured both as a function of liposome-biofilm incubation time and incubation time with the substrates. Bacterial inhibition increases with both liposome-biofilm and substrate-biofilm incubation time and with the extent of enzyme encapsulation. The reactive liposomes also display antibacterial activity in the presence of saliva. The reactive liposomes have potential value in the context of oral hygiene.

Abstract
Phospholipid liposomes have been prepared from phospholipid mixtures including dipalmitoylphosphatidylcholine/phosphatidylinositol (DPPC/PI) and DPPC/dipalmitoylphosphatidylglycerol (DPPC/DPPG) mixtures and targeted to adsorbed biofilms of the skin-associated bacteria Staphylococcus epidermidis and Proteus vulgaris and the oral bacterium Streptococcus sanguis. The effects of time, liposome concentration and density of bacteria in the biofilm have been studied in detail for Staphylococcus epidermidis. The targeting (as assessed by the apparent monolayer coverage of the biofilms by liposomes) to the biofilms was found to be sensitive to the mol% of PI and DPPG in the liposomes and optimum levels of PI were found for targeting to each bacterium. The use of PI and DPPG-containing liposomes for the delivery of the bactericide, Triclosan, to biofilms of Staphylococcus epidermidis was studied as a function of the amount of Triclosan carried by the liposomes. All the liposome systems tested inhibited the growth of bacteria from the biofilms after brief (2 min) exposure to Triclosan-carrying liposomes. At low Triclosan levels bacterial growth inhibition by Triclosan-carrying liposomes exceeded that by an equivalent level of free Triclosan. After short periods (min) of exposure of biofilms to Triclosan-carrying liposomes the bactericide was shown to preferentially concentrate in the biofilms relative to its liposomal lipid carrier. The results suggest that phospholipid liposomes with appropriately chosen lipid composition have potential for the targeting and delivery of bactericide to bacteria.

Abstract
A theoretical model has been developed for the interaction of the surface polymers of the bacterial glycocalyx with liposomes incorporating lipids with polyhydroxy headgroups such as phosphatidylinositol (PI). The theory is based on a lattice model and equations are derived for the potential energy of interaction between the surfaces of a bacterium and a liposome as a function of their separation. It is shown that a relatively small energy of interaction, less than that of a single hydrogen bond, between the polyhydroxyl headgroup of the liposomal lipid and bacterium surface polymer residues could give rise to a potential energy of interaction in excess of the classical double layer repulsive force and attractive dispersion force interactions. The most important prediction of the theory is that the potential energy of interaction goes through a minimum as a function of the polyhydroxy lipid (PI) concentration in the liposomal surface, thus predicting an optimal liposomal composition for adsorption of liposome to bacterium. This result is in concordance with the adsorption of dipalmitoylphosphatidylcholine-PI liposomes to a range of biofilms of oral and skin-associated bacteria on solid supports, where optimum levels of PI for adsorption have been found. The theory demonstrates that subtle changes in the composition of liposomal and bacterial surfaces involving relatively small interaction energies can markedly influence the nature of their interactions.

Abstract
Phospholipid (dipalmitoylphosphatidylcholine (DPPC) plus phosphatidylinositol (PI)) proteoliposomes with surface bound lectins (succinylated concanavalin A (s con A) and wheat germ agglutinin (WGA)) have been prepared covering a range of size and surface density of lectin. Negatively charged phospholipid liposomes from DPPC-PI mixtures covering a range of PI mole % and positively charged liposomes from DPPC-cholesterol-stearylamine (SA) mixtures covering a range of SA mole % have been prepared. The targeting of the liposomes and proteoliposomes to a range of oral and skin-associated been prepared. The targeting of the liposomes and proteoliposomes to a range of oral and skin-associated bacterial biofilms has been investigated. The oral bacteria Streptococcus mutans and gordonii and the skin-associated bacterium Coryneform hofmanni can be targeted with s con A bearing proteoliposomes while the skin associated bacterium Staphylococcus epidermidis can be targeted with WGA bearing proteoliposomes. Both oral and skin-associated bacteria can be targeted with positively charged liposomes although the extents of adsorption to the biofilm are low except for Staphylococcus epidermidis. In the case of negatively charged liposomes targeting is critically dependent on the PI content of the liposomes and for all the bacteria studied optimum levels PI for targeting have been found. The adsorption of the oral bacterium Streptococcus gordonii to immobilised monolayers having the optimum PI level for adsorption has been studied by total internal reflection microscopy (TIRM). Both the phospholipid and proteoliposomes have been used to deliver the bactericide Triclosan to biofilms. All the systems studied inhibited bacterial growth to varying degrees.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
31P- and 1H-NMR spectroscopy of small, unilamellar egg yolk phosphatidylcholine (PC) vesicles in the presence of the lanthanide ion Dy3+ have been used to study the effect of various n-alcohols on the permeability induced by the action of the enzyme phospholipase A2 (PLA2). The method allows the monitoring of the number of PC and lysoPC molecules in the outer and inner monolayers. The results indicate that the initial rate of hydrolysis of PC by PLA2 is increased by all the n-alcohols but in a chain-length dependent manner and that the maximum rate occurs at n = 8 (octan-1-ol). The subsequent rate is dependent upon the rate of transbilayer lipid exchange (flip-flop) of PC molecules from the inner to the outer monolayer. The vesicles only become permeable to the Dy3+ ions when lysoPC is mobilised in the flip-flop process of exchange of lipid molecules between the two monolayers. The n-alcohols affect both the time taken to initiate flip-flop of inner monolayer PC and the subsequent rate of permeability to Dy3+. The n-alcohols are seen to affect all the above rates in an identical chain-length dependent manner, indicating a common cause for all observations which we identify as the degree of clustering of the n-alcohol molecules in the bilayer. The results are discussed in terms of the chain-length dependent mechanism of n-alcohol interactions with the membrane and the mechanism by which the vesicles become permeable to Dy3+ ions.

Abstract
1H-NMR spectroscopy of small, unilamellar dipalmitoyl phosphatidylcholine (DPPC) vesicles in conjunction with the lanthanide shift reagent Pr3+ was used to study the effect of Zn2+ and Ca2+ ions on the permeability induced at the lipid phase transition temperature (Tc) of the vesicles and by the bee venom polypeptide melittin. In addition, the effects of Zn2+ and Ca2+ were studied on Triton X-100 stabilized channels at Tc and in the presence of n-alcohols. The results show that the presence of 10 mM Zn2+ and Ca2+ inhibited most of the forms of vesicular permeability investigated. The results are discussed in terms of the nature of the binding of the metal ions to the vesicles and support the proposal that one biological function of Zn2+ and Ca2+ is protection against membrane damage.

Abstract
The effect of a series of n-alcohols on the permeability of small, unilamellar dipalmitoyl phosphatidylcholine (DPPC), dimyristoyl phosphatidylcholine (DMPC) and distearoyl phosphatidylcholine (DSPC) vesicles at the gel-to-liquid crystal phase transition temperature was investigated. It was found that the permeability took the form of the transient lysis of a fraction of the population of vesicles. The effect on this lysis of the n-alcohols was seen to be very chain-length dependent, with a minimum at n = 8 (octan-1-ol) for DPPC vesicles. A similar minimum was observed in the presence of 0.1 mM Triton X-100, but the detergent could then interact with certain of the alcohols to produce permanent channels. The results are discussed in terms of the semi-empirical model of Brasseur et al. (1985) Biochim. Biophys. Acta 814, 227-236, for the interaction of the n-alcohols with a DPPC membrane. The effect of various n-alcohols on the outer and inner monolayers of DPPC vesicles was also studied and the results related to their fluidising effect, allowing channels to open at the phase transition temperature.

Abstract
Propranolol introduced by a cut-end method into atrial trabeculae evoked negative inotropic response without any significant changes in basic electrical parameters. This effect was resistant to noradrenaline but not to dibutyryl cAMP. These results suggest that existence of intracellular beta adrenoreceptors involved in the control of the contraction.
