Evaluation of the impact of a psycho-educational intervention for people diagnosed with schizophrenia and their primary caregivers in Jordan: A randomized controlled trial
Ā© Hasan et al. Background: Psycho-educational interventions for people diagnosed with schizophrenia (PDwS) and their primary caregivers appear promising, however, the majority of trials have significant methodological shortcomings. There is little known about the effects of these interventions delivered in a booklet format in resource-poor countries. Methods: A randomized controlled trial was conducted from September, 2012 to July, 2013 with 121 dyads of PDwS and their primary caregivers. Participants aged 18 years or older with DSM-IV schizophrenia or schizoaffective disorder, and their primary caregivers, from four outpatient mental health clinics in Jordan, were randomly assigned to receive 12 weeks of a booklet form of psycho-education, with follow-up phone calls, and treatment as usual [TAU] (intervention, n = 58), or TAU (control, n = 63). Participants were assessed at baseline, immediately post-intervention (post-treatment1) and at three months follow-up. The primary outcome measure was change in knowledge of schizophrenia. Secondary outcomes for PDwS were psychiatric symptoms and relapse rate, with hospitalization or medication (number of episodes of increasing antipsychotic dosage), and for primary caregivers were burden of care and quality of life. Results: PDwS in the intervention group experienced greater improvement in knowledge scores (4.9 vs -0.5; p <0.001) at post-treatment and (6.5 vs -0.7; p <0.001) at three month-follow-up, greater reduction in symptom severity (-26.1 vs 2.5; p <0.001: -36.2 vs -4.9; p <0.001, at follow-up times respectively. Relapse rate with hospitalization was reduced significantly at both follow-up times in the intervention group (p <0.001), and relapse with medication increased in the intervention group at both follow-up times (p <0.001). Similarly there was a significant improvement in the primary caregivers knowledge score at post-treatment (6.3 vs -0.4; P < 0.001) and three month-follow-up (7.3 vs -0.7; p <0.001). Primary caregivers burden of care was significantly reduced in the intervention group (-6.4 vs 1.5; p <0.001; -9.4 vs 0.8; p <0.001), and their quality of life improved (9.2 vs -1.6; p = 0.01; 17.1 vs -5.3; p <0.001) at post-treatment and three month-follow-up. Conclusions: Psycho-education and TAU was more effective than TAU alone at improving participants' knowledge and psychological outcomes
Enzymes used in detergents: Lipases
Microbial lipases are an important group of biotechnologically valuable enzymes, because of the versatility of their applied properties and ease of mass production. Lipases of microbial origin are widely diversified in their enzymatic properties and substrate specificity, which make them very attractive for industrial applications. This review describes the applications of microbial lipases in detergents. Enzymes can reduce the environmental load of detergent products as the chemicals used in conventional detergents are reduced; they are biodegradable, non-toxic and leave no harmful residues. Besides lipases, other enzymes are widely used in household cleaning products, in laundering, medical, agriculture, etc. This article also reviews the use of enzymes, especially lipases as detergents and different types of lipase containing detergents available in the market.Key words: Detergents, enzymes, lipases
3D Bioprinted cancer models: Revolutionizing personalized cancer therapy
After cardiovascular disease, cancer is the leading cause of death worldwide with devastating health and economic consequences, particularly in developing countries. Inter-patient variations in anti-cancer drug responses further limit the success of therapeutic interventions. Therefore, personalized medicines approach is key for this patient group involving molecular and genetic screening and appropriate stratification of patients to treatment regimen that they will respond to. However, the knowledge related to adequate risk stratification methods identifying patients who will respond to specific anti-cancer agents is still lacking in many cancer types. Recent advancements in three-dimensional (3D) bioprinting technology, have been extensively used to generate representative bioengineered tumor in vitro models, which recapitulate the human tumor tissues and microenvironment for high-throughput drug screening. Bioprinting process involves the precise deposition of multiple layers of different cell types in combination with biomaterials capable of generating 3D bioengineered tissues based on a computer-aided design. Bioprinted cancer models containing patient-derived cancer and stromal cells together with genetic material, extracellular matrix proteins and growth factors, represent a promising approach for personalized cancer therapy screening. Both natural and synthetic biopolymers have been utilized to support the proliferation of cells and biological material within the personalized tumor models/implants. These models can provide a physiologically pertinent cellācell and cellāmatrix interactions by mimicking the 3D heterogeneity of real tumors. Here, we reviewed the potential applications of 3D bioprinted tumor constructs as personalized in vitro models in anticancer drug screening and in the establishment of precision treatment regimens
Psychrotrophic bacteria isolated from -20Ā°C freezer
Three psychrotrophic bacteria, morpho-physiologically, identified as Bacillus subtilis MRLBA7, Bacillus licheniformis MRLBA8 and Bacillus megaterium MRLBA9 were isolated from -20°C freezer of the Microbiology Research Laboratory (MRL), Quaid-i-Azam University, Islamabad, Pakistan. These strains were able to grow aerobically at 6°C but not at 40°C except MRLBA8 that could grow at 48°C. None of the isolates showed inhibition of growth in the presence of glycerol. Isolate MRLBA7, bearing central spore, grew in the presence of 30% glycerol at 0°C after 48 h of incubation and showed maximum growth without glycerol at 25°C after 24 h. Isolate MRLBA8 showed growth in the presence of 50% glycerol at 4°C after 72 h of incubation and maximum growth was observed at 20°C in the absence ofglycerol. Isolate MRLBA9 showed growth at 6°C in the presence of 40% glycerol after 48 h of incubation and maximum growth was observed at 25°C in the absence of glycerol. Isolates were susceptible to antibiotics except Bacillus subtilis MRLBA7 that exhibited antibiotic resistance against penicillin and fosphomycin, Bacillus licheniformis MRLBA8 against aztreonam and fosphomycin, and Bacillus megaterium MRLBA9 against vancomycin and penicillin. The growth profile and biochemical characteristics of all the isolates were rather similar to that of mesophilic counterparts except adaptation to low temperature. These strains could be used as model microbial strains for characterization of food contaminants in freezers, to understand the mechanism of antibiotic resistanceinduced at low temperature and as a source of psychrotrophic enzymes

Rationalizations and identity conflict following smoking relapse: a thematic analysis
Introduction: Little is known about how smokers respond cognitively and emotionally to the experience of ālateā relapse after the acute withdrawal phase. This study assessed the kinds of thoughts and feelings that emerge in order to provide a basis for quantitative research assessing prevalence of different types of response and implications for future quit attempts. Methods: Face-to-face in-depth interviews were conducted among 14 people attending a quit smoking clinic in Malaysia who had relapsed after at least 6 weeks of abstinence. Transcripts were analyzed using thematic analysis to enable emergence of important aspects of the experience. Results: Following relapse, smokers often engaged in rationalizations and activities to minimize worry about the harmful effects of smoking by switching to a lower-tar cigarette, reducing the number of cigarette smoked, attempting to reduce cigarette smoke inhalation, comparing themselves with other smokers, and minimizing the health risks associated with smoking. In some cases, smokers retained a ānon-smokerā identity despite having relapsed. Conclusion: Smoking relapsers rationalize their failure to quit and minimize their health risk in order to protect their image as non-smokers while it remains a source of identity conflict

Vertically aligned smooth ZnO nanorod films for planar device applications
The growth of smooth and continuous zinc oxide (ZnO) films, consisting of densely packed vertical ZnO nanorods with (002) crystal orientation on silicon substrates has been achieved in this work by a chemical solution method. These ZnO thin films have much stronger photoluminescence emission than those from discrete ZnO nanorods under identical conditions. Large area surface acoustic wave devices were fabricated on these films using conventional photolithography, and exhibited two well-defined resonant modes of the Sezawa wave and its harmonic mode

Unravelling the optical responses of nanoplasmonic mirror-on-mirror metamaterials
Mirror-on-mirror platforms based on arrays of metallic nanoparticles, arranged top-down or self-assembled on a thin metallic film, have interesting optical properties. Interaction of localized surface-plasmons in nanoparticles with propagating surface-plasmons in the film underpins the exotic features of such platforms. Here, we present a comprehensive theoretical framework which emulates such a system using a five-layer-stack model and calculate its reflectance, transmittance, and absorbance spectra. The theory rests on dipolar quasi-static approximations incorporating image-forces and effective medium theory. Systematically tested against full-wave simulations, this simple approach proves to be adequate within its obvious applicability limits. It is used to study optical signals as a function of nanoparticle dimensions, interparticle separation, metal film thickness, the gap between the film and nanoparticles, and incident light characteristics. Several peculiar features are found, e.g., quenching of reflectivity in certain frequency domains or shift of the reflectivity spectra. Schemes are proposed to tailor those as functions of the mentioned parameters. Calculating the system's optical responses in seconds, as compared to much longer running simulations, this theory helps to momentarily unravel the role of each system parameter in light reflection, transmission, and absorption, facilitating thereby the design and optimisation of novel mirror-on-mirror systems
