title: Demographic, clinical and lifestyle predictors for severity of erectile dysfunction and biomarkers level in Malaysian patients

description: The incidence of erectile dysfunction (ED) is rising worldwide and its prevalence is one of the main health concerns that affect overall men well-being in Malaysia. The cluster of demographic, clinical and lifestyle factors may have contributed to the severity of ED and changes in biomarkers level; nevertheless these have not been studied extensively. This cross sectional study involved a total of 276 patients with 138 was diagnosed with ED. The demographic, clinical, lifestyle factors and severity of ED were assessed using a set of questionnaire and the International Index of Erectile Function (IIEF-5). Meanwhile, Total Testosterone (TT) and Asymmetric dimethylarginine (ADMA) levels were determined using the enzyme-linked immunosorbant assay (ELISA). Binary logistic regression test was used to demonstrate the predictors of severity of ED, TT and ADMA levels. Significant predictors for worsening of severity of ED are self-employed [10.55 (0.43 - 257.06), p=0.004], pensioner [8.07 (0.19 - 352.45), p=0.026], non-government employee [1.16 (0.05 - 26.26), p=0.04] and TT [0.41 (0.25 - 0.69), p=0.001]. Nevertheless, pensioner [0.08 (0.01 - 0.87), p=0.038] and unemployed [0.04 (0.01 - 0.42), p=0.007], were the predictors that may influence the changes of TT levels. On the other hand, academic qualification (secondary) [4.51 (0.48 - 42.83), p=0.014] and intensity of physical activities (&lt; 1 hour/day) [2.61 (0.65 - 10.48), p=0.008] were the predictors which were more likely to influence the changes of ADMA levels in ED patients. TT and ADMA levels were influenced by demographic and lifestyle factors whilst severity of ED was predicted by demographic and clinical factors in Malaysian ED population. These predictors may provide new knowledge on risk factors of severity of ED and help in management of ED. Thus, the predictive models could serve as a primary guidance to physicians to ensure ED being managed and treated more effectively.

title: Molecular characterization of Mycobacterium tuberculosis and Mycobacterium bovis isolates by Enterobacterial Repetitive Intergenic Consensus-PCR

description: Tuberculosis (TB) is an infectious disease in which the molecular typing methods allow to have important information about the dynamics of transmission and to assist properly in disease control. Although the ERIC-PCR (Enterobacterial repetitive intergenic consensus-PCR) assay is fast and easy to perform, scarce studies have reported its use in epidemiological studies in TB outbreaks. In this study, we aimed to genotype Mycobacterium tuberculosis and M. bovis isolates by ERIC-PCR and compare its discriminatory power with two other classically used methods: 12 loci-MIRU (Mycobacterial Interspersed Repetitive Units) and Spoligotyping. The M. tuberculosis isolates studied were from northwestern and southwestern and M. bovis from northwestern Parana, Brazil. ERIC-PCR rendered banding patterns with great diversity (1 to 12 bands) of molecular sizes, ranging from 100 to 1600 bp. ERIC-PCR showed to be fast, simple and affordable to differentiate isolates. ERIC-PCR would be an important tool in the epidemiology of TB as screening in case of outbreak, which demands rapid intervention. However if any doubt persist, as it may occur with the application of only one genotypic method, other genotyping methods should be applied and carefully interpreted, always with additional epidemiological information.

title: Determination of cefotaxime, cefoperazone, ceftazidime and cefadroxil using surface plasmon resonance band of silver nanoparticles

description: The aim of this work is to evaluate simple, sensitive, effective and validated procedures for the determination of cefotaxime, cefoperazone, ceftazidime and cefadroxil. In this study, the methods based on the ability of the cited drugs to reduce Ag+ ions to silver nanoparticles (Ag-NPs) in the presence of Polyvinyl Pyrrolidone (PVP) as a stabilizing agent producing very intense surface plasmon resonance peak of Ag-NPs (λmax. = 410-430 nm). The plasmon absorbance of the Ag-NPs allows the quantitative spectrophotometric determination of the cited drugs. The calibration curves are linear with concentration ranges of 0.4-3.2, 1-8, 0.5-4.0 and 1.5-9.0 µg/mL for cefotaxime, cefoperazone, ceftazidime and cefadroxil, respectively. Apparent molar absorptivity, detection and quantitative limits are calculated. Applications of the proposed methods to representative pharmaceutical formulations are successfully presented. The extracellular synthesis of nanoparticles is fast, and the method doesn’t require various elaborate treatments and tedious extraction procedures.

title: Appraisal of acute oral toxicity of glucuronoxylan hydrogel from Mimosa pudica seeds

description: Glucuronoxylan hydrogel (GXH) isolated from M. pudica seeds was assessed for acute toxicology in albino mice that were alienated into four groups. Three groups, i.e., II, III and IV received GXH at a dose of 1, 2 and 5 g/kg, respectively while group I was retained untreated and provided routine diet. After administering GXH, mice were examined for vomiting, diarrhea, allergy and tremors for 8 h. All animals were carefully observed for food and water consumption at 1, 2, 3, 7 and 14 day after administering GXH. At the end of studies, blood samples were drawn for investigation of hematological and biochemical parameters. All animals were sacrificed, relative body weight of vital organs was calculated and their histopathology was studied. It was concluded that there was insignificant difference in body weight, behavioral pattern, food and water intake among treated and control groups. Haematology and biochemistry of blood samples from all groups were found analogous. Histopathological evaluation of vital body organs exhibited no lesions in all groups. Ocular, cardiac and dermal safety of GXH was also established on albino rabbits.

title: Correlation between rheological properties and capillary fixation for modelling creams

description: The Brazilian male beauty market occupies the second place in world consumption of cosmetics. Among the numerous products consumed by such audience is the capillary fixation mask, which is mainly composed by fixatives. These additives act on stabilizing the cosmetic emulsion, protecting the hair against moisture and also increasing the intensity of hair fixation. In this work, three formulations for modelling creams were prepared by different concentrations of the fixatives StylezeTM W20 and PVP K90 and their properties characterized by physicochemical, rheological and sensory analysis. The capillary masks produced were stable oil-in-water (O/W) emulsions with uniform droplets of 2.05-2.82 μm sizes and pseudoplastic thixotropic behavior (0.19 &lt; n &lt; 0.26). It was possible to correlate the increased concentration of PVP K90 to a greater thixotropy and an improved yarn fixation, despite the worsening in the spreadability of the formulations. These results suggest properly conducted rheological measurements can contribute to the prediction of the emulsion’s sensory properties, which can save time and funds on the development of new cosmetics.

title: Beta-glucan prevents toxic effects of 2,3,7,8-TCDD in terms of oxidative and histopathological damage in heart tissue of rats

description: 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a widespread environmental contaminant which causes severe toxic effects. Despite there is some suggestion concerning with TCDD induced cardiotoxicity such as formation of free radicals, the main mechanism has not been entirely explained. Beta-glucan is known as strong antioxidant matter and can scavenge free radicals. Therefore this study aimed to investigate the protective effects of beta-glucan against TCDD induced cardiotoxicity in rats. In this study, 2-3 months of age and 190-250 g in weight 32 rats were randomly divided into four equal groups (n=8 for each group). Group 1 was control; Group 2 was TCDD group (2 µg/kg/week); group 3 was the beta-glucan group(50 mg/kg/day), and group 4 was TCDD and beta-glucan treatment group. The heart samples were taken from rats after 21 days treatment. The results were shown that Despite TCDD exposure visibly caused to increase (p ≤ 0.001) in TBARS levels, It caused a visible decline in the levels of GSH, CAT, GSH-Px, and SOD. However Beta glucan significantly increased GSH, CAT, GSH-Px, SOD levels and decreased generation of TBARS. Additionally, our histopathological observations were in agreement with the biochemical results. In conclusion, Beta-glucan treatment exhibited protective activity on TCDD induced cardiotoxicity.

title: Stability and in vivo efficiency of natural cosmetic emulsion systems with the addition of vegetable oils

description: The aim of the paper is to test stability and biophysical properties of hydrophilic and lipophilic emulsions with selected vegetable seed oils: Limnanthes alba, Prunus amygdalus dulcis, Cannabis sativa, Rosa rubiginosa and Hellianthus annuus. Biophysical properties of emulsions are investigated in vivo using non-invasive instrumental methods (corneometry, tewametry and pH) in a group of 12 healthy women volunteers. Their stability profiles (colour, phase separation and centrifugation) under various temperatures (9, 25, 37 and 57 °C) and storage time (24 hours, 2, 7, 14, 21 and 28 days) were monitored. The moisturising activities of the emulsions supplemented with various oils were comparable. The lipophilic emulsions showed a better ability to improve the condition of the skin barrier due to formation of a surface lipid film. The tested formulations regulated the pH of the skin towards neutral values. Lipophilic emulsions showed earlier phase separation and changes in colour. The greatest resistance to thermal stress during storage was observed for the emulsion bases. Emulsions containing oils, except for those with rosehip and hempseed oils, were stable up to the temperature of 37 °C. The studied emulsion systems are excellent vehicles of vegetable oils and exhibit relatively good stability, benefiting the natural properties of skin.

title: Therapeutic itinerary: trajectory for resolution of adverse events of patients using warfarin in Southern Brazil

description: Warfarin is the most used anticoagulant in primary health care. Due to the narrow therapeutic index, its users are more susceptible to adverse events. The objective of this study was to describe the itinerary of the public health sector patients for resolution of adverse events related to warfarin. It is a prospective open cohort, held for a period of 18 months with warfarin users of the Brazilian public health system. Data were collected by monthly interviews and from patient records. Results: Sixty nine patients were interviewed, 64 of them completed monitoring and five died. Bleeding and venous thromboembolism were more frequent in patients starting treatment. It was observed that when adverse events have occurred, in most cases the patient held self-care at home (57%). During the follow-up, five patients were hospitalized for bleeding. Approximately half of the patients did not present their INR exams to the doctor. Conclusions: This study demonstrates weaknesses in caring for these patients and the need to accompany them, aiming to standardize and guide the itinerary of the anticoagulated patient to solve their problems and improve safety in drug treatment, with less cost to the public health system.

title: Effects of Cinnamomum cassia extract on oxidative stress, immunreactivity of iNOS and impaired thoracic aortic reactivity induced by type II diabetes in rats

description: Type II diabetes is known to cause neuropathy, nephropathy and retinopathy. However, cardiovascular disorders associated with diabetes have been ignored. In traditional medicine, cinnamon (Cinnamomum cassia) bark has been used for its abilities to relieve fever, inflammation and chronic bronchitis. In the present study, the effect of Cinnamomum cassia extract (CN) on the thoracic aorta in an experimental type II diabetes model was investigated. In rats administered with nicotinamide + streptozotocin, significant endothelial dysfunction and oxidative stress were characterised by increased inducible nitric oxide synthase (iNOS) and decreased insulin/proinsulin levels. This impairment was prevented by administering 1000 mg/kg metformin or 500-1000-1500 mg/kg CN. CN administration attenuated the inflammatory response by decreasing the levels of malondialdehyde (MDA), Nitric oxide (NO) and increasing Glutathione peroxidase (GPx), glutathione (GSH). In addition, CN administration was shown to cause down-regulating effects on iNOS in thoracic aorta. These findings reveal that CN could prevent chronic complications of experimentally induced type II diabetes by attenuating inflammation, oxidant/antioxidant imbalance, and normalised contraction and relaxion responses in the thoracic aorta.
