Resumo O objetivo do presente estudo é avaliar os efeitos das nanopartículas de selênio no crescimento, hematologia e digestibilidade dos nutrientes de alevinos de Labeo rohita. Os alevinos foram alimentados com sete dietas isocalóricas à base de farinha de girassol suplementada com diferentes concentrações de nanopartículas, nomeando T1 a T7 (0, 0,5, 1, 1,5, 2, 2,5 e 3 mg / kg), com 5% do peso corporal úmido enquanto o óxido crômico foi usado como um marcador indigesto. Após a experimentação por 90 dias, o grupo tratado com T3 (nível 1mg / kg -1Se-nano) mostrou o melhor resultado em parâmetros hematológicos (WBC’s 7,97 × 103mm-3, RBC’s 2,98 × 106mm-3 e contagem de plaquetas 67), digestibilidade dos nutrientes (proteína bruta: 74%, extrato de éter: 76%, energia bruta: 70%) e desempenho de crescimento (ganho de peso 13,24 g, ganho de peso % 198, taxa de conversão alimentar 1,5, taxa de sobrevivência 100%) em comparação com os outros grupos de tratamento. As taxas de crescimento específicas foram encontradas significativamente mais altas em T5 do que em outros grupos. O presente estudo indicou efeito positivo de 1 mg / kg de nanopartículas de Se no avanço do crescimento, parâmetros hematológicos e digestibilidade de nutrientes de alevinos de L. rohita.

Abstract The aim of the present study is to assess the effects of selenium nanoparticles on the growth, hematology and nutrients digestibility of Labeorohita fingerlings. Fingerlings were fed with seven isocaloric sunflower meal-based diet supplemented with different concentrations of nanoparticles naming T1 to T7 (0, 0.5, 1, 1.5, 2, 2.5, and 3 mg/kg), with 5% wet body weight while chromic oxide was used as an indigestible marker. After experimentation for 90 days T3 treated group (1mg/kg -1Se-nano level) showed the best result in hematological parameters (WBC’s 7.97 ×103mm-3, RBC’s 2.98 ×106 mm-3 and Platelet count 67), nutrient digestibility (crude protein: 74%, ether extract: 76%, gross energy: 70%) and growth performance (weight gain 13.24 g, weight gain% 198, feed conversion ratio 1.5, survival rate 100%) as compared to the other treatment groups. Specific growth rates were found significantly higher in T5 than in other groups. The present study indicated positive effect of 1 mg/kg Se-nanoparticles on growth advancement, hematological parameters, and nutrients digestibility of L. rohita fingerlings.

Abstract The goal of this study is to review the overall prevalence, burden, and distribution of the dengue disease in Pakistan from 2000 to 2019. Literature was searched using different search engines like Google scholar, PubMed, etc. providing the keywords “Dengue disease/infection, Dengue virus, DENV, DF/DHF/ DSS Pakistan”. All the published research papers/reports on the dengue virus over the period 2000 to 2019 were studied and selected data were summarized using MS Excel for windows such as total cases, age wise, gender, DENV serotype distribution, total DHF, and DSS patients. The literature providing insufficient data was excluded. The total number of cases reported during 2000-19 were 201,269. The maximum number of cases during the mentioned literature survey period was reported in Khyber Pakhtunkhwa (KP) (23.3%) followed by Punjab (3.8%) and Sindh (1.9%). The majority of dengue-infected cases were reported as Dengue fever (74.4%) followed by DHF (24.1%) and DSS (1.5%). Overall the deaths during the mentioned literature survey were 1082, of which the maximum mortalities were reported from KP (N=248) followed by Punjab (N=220). DENV remains a major public health problem in Pakistan and seems to remain endemic for a long time. The total prevalence of dengue infection is increased accordingly with time from 2000 to 2019. Moreover, all the four serotypes exist in Pakistan with increased mortalities.

Resumo A literatura foi examinada através de diferentes mecanismos de pesquisa, como Google Acadêmico, PubMed, etc., fornecendo as palavras-chave “Dengue disease/infection, Dengue virus, DENV, DF/DHF/ DSS Pakistan”. Todos os trabalhos/relatórios de pesquisa publicados sobre o vírus da dengue no período de 2000 a 2019 foram analisados e os dados selecionados foram coletados e resumidos usando o MS Excel para janelas como total de casos, idade, sexo, distribuição de sorotipos, total de DHF e pacientes com DSS. A literatura que forneceu dados insuficientes foi excluída. O número total de casos notificados de 2000 a 2019 foi de 201.269. O número máximo de casos durante o período de levantamento da literatura mencionado foi relatado em KP (23,3%), seguido por Punjab (3,8%) e Sindh (1,9%). A maioria dos casos de infecção por dengue foi relatada como Dengue (74,4%), seguida por FHD (24,1%) e DSS (1,5%). No geral, as mortes durante a pesquisa de literatura mencionada foram 1.082, das quais as morbidades máximas foram relatadas em KP (248), seguidas por Punjab, com um total de 220 mortes. O DENV continua sendo um grande problema de saúde pública no Paquistão e é considerado endêmico agora e provavelmente permanecerá por muito tempo. A prevalência total de infecção por dengue foi aumentada conforme a pesquisa de literatura publicada entre 2000 e 2019. A mortalidade por DENV também aumentou. Todos os 4 sorotipos, bem como em várias formas, existem no Paquistão.

ABSTRACT Aspergillus fumigatus is a respiratory pathogen, which has the potential to cause brooder pneumonia in poultry chicks and aspergillosis in birds and farmers. Frequent and irrational use of antifungals has led to the development of resistance in the fungal species. The present study aimed to evaluate the antifungal activity of essential oils (EOs) from four different spices against multi-drug resistant (MDR) A. fumigatus isolated from 40 poultry feed samples. Twenty fungal isolates were identified to be A. fumigatus based on the macroscopic and microscopic characteristics, which were confirmed by targeting and amplifying the species-specific rodA gene (313 bp). Five (5/20) isolates were found to be MDR by the disk diffusion method. EOs were tested as an alternative strategy for 5 MDR isolates of A. fumigatus. Clove EO provided better activity by 6 log10 reduction for 30-90 min exposure as compared to other EOs, therefore, shortlisted for well-diffusion and minimum inhibitory concentration (MIC) method. Clove EO provided promising results as compared to fluconazole, amphotericin B, ketoconazole, nystatin and voriconazole as its mean ZOI (39.6 ± 6.34) were better than all other commercial antifungals (p< 0.001). Mean MIC was reported to be 0.195 ± 0.11 µl/ml. Safety testing of the EO produced 74-82% cell viability for the range of 0.390 - 0.097 µl/ml as compared to DMSO. Findings of the present study highlight that clove EO can be source of a good therapeutic agent for infections of MDR isolates of A. fumigatus.

RESUMO Aspergillus fumigatus é um patógeno respiratório, que tem o potencial de causar pneumonia incubadora em pintos e aspergilose em aves e criadores. O uso frequente e irracional de antifúngicos tem levado ao desenvolvimento de resistência nas espécies fúngicas. O presente estudo teve como objetivo avaliar a atividade antifúngica de óleos essenciais (OEs) de quatro diferentes especiarias contra A. fumigatus multirresistente (MDR) isolado de 40 amostras de ração de aves. Vinte isolados fúngicos foram identificados como A. fumigatus com base nas características macroscópicas e microscópicas, que foram confirmadas pelo direcionamento e amplificação do gene rodA espécie-específico (313 pb). Cinco (5/20) isolados foram considerados MDR pelo método de difusão em disco. OEs foram testados como uma estratégia alternativa para 5 isolados MDR de A. fumigatus. Clove EO forneceu melhor atividade por redução de 6 log10 para exposição de 30-90 min em comparação com outros OEs, portanto, pré-selecionado para difusão e método de concentração inibitória mínima (MIC). Clove EO forneceu resultados promissores em comparação com fluconazol, anfotericina B, cetoconazol, nistatina e voriconazol, com ZOI médio (39,6 ± 6,34) melhor do que todos os outros antifúngicos comerciais (p < 0,001). A MIC média foi de 0,195 ± 0,11 µl/ml. O teste de segurança do EO produziu 74-82% de viabilidade celular para a faixa de 0,390 - 0,097 µl/ml em comparação com DMSO. Os resultados do presente estudo destacam que o EO de cravo pode ser fonte de um bom agente terapêutico para infecções de isolados multirresistentes de A. fumigatus.

In post disastrous situations, coordinated and integrated interventions aimed at relief and rehabilitation not only help facilitate reaching out to the affected communities in a timely fashion but also pave the way to channel scarce and valued resources towards end users in an efficient and effective manner. This article attempts to trace the origins and gradual development of 'inter-agency collaboration' and the implications thereof for disaster management strategies in Pakistan through an analysis of relief and rehabilitation interventions undertaken by the Government of Pakistan in collaboration with local and international Non-governmental Organisations (NGOs) and relief agencies in the ex post of the 2005 earthquake. Data for this study were collected through structured and semi-structured interviews from government officials, representatives of NGOs and relief agencies and ordinary women and men in the earthquake stricken localities of Balakot and Mansehra districts of Pakistan. On the heels of the 2005 earthquake, both local NGOs and faith-based organisations in concert with international NGOs and relief agencies from around the world rushed to assist Pakistan in it's rescue and relief operations at a time when the country was faced with the twin dilemma of both the non-existence of peculiar institutional arrangements for disaster management and a lack of the necessary technical and financial resources. The aftermath of the 2005 earthquake offered opportunity to the Government of Pakistan and the NGOs and relief agencies alike to transform their individual interventions into a robust and organised 'inter-agency collaboration', which was later on realised in the form of establishment of a national disaster management organisation called the 'Earthquake Reconstruction and Rehabilitation Authority (ERRA)'. The establishment of ERRA not only paved the way for avoiding duplication and wastage of resources but also ensued in reaching out to the affected communities in a timely fashion. The Pakistani case offers implications in terms of highlighting the salience of establishing 'inter-agency collaboration' in other settings.

As emphasised in Islamic sources, justice is one of the most important issues covered in the religion of Islam. In fact, justice is a central theme in Islam and has a special value in this regard. Conversation about justice and its nature, as well as its realisation in human communities, has been thus far a necessity in human life. Actually, the establishment and implementation of justice in all areas are crucial for the utopia. Given the importance of this subject, the present study aims to determine and explain the components of the justice-oriented Islamic community based on the teachings of Nahj al-Balaghah. Therefore, the components that introduce justice orientation in the Islamic community are extracted from the sermons, letters and wise sayings (viz. narrations) of Nahj al-Balaghah. Afterward, the extracted components are classified based on the similarity of the themes and concepts. In the end, five classifications are introduced, including distributive justice, procedural justice, interactional justice, social justice and fairness. CONTRIBUTION: Based on the determined indices, the model of justice-oriented Islamic community is developed. It is thus recommended to pay more attention to the realisation of a justice-oriented Islamic community by researchers and leaders. This is mainly because of the fact that the opposite of a justice-oriented community is one with injustice, where oppression and disrespect for the rights of others occur, divine blessings change, divine wrath and anger are provoked and destruction approaches

Kinetics of oxidation of L-lysine by permanganate ion in a perchloric acid medium was investigated to explore the order of the reaction with respect to oxidant and substrate and to study the catalytic behaviour of sodium lauryl sulphate (SLS) and polyethylene glycol (PEG). The reaction was found to be first-order with respect to the oxidant and the substrate and zero-order with respect to hydrogen ion. Changes in the sodium sulphate concentration produce a non-significant variation in the rate of the reaction. SLS and PEG were found to catalyze the reaction. Surfactant catalysis was modelled by Piszkiewicz's cooperativity model, while polymer catalysis was explained with the help of the Benesi-Hildebrand equation. The temperature dependence of the rate of the reaction was elucidated, and activation parameters were obtained. Interestingly, the reaction was found to possess positive activation entropy indicating the dissociative nature of the transition state and outer-sphere electron transfer mechanism. A mechanism of the reaction that is supported by the experimental findings was suggested.

RESUMO: Este estudo preliminar fornece o consumo tradicional de vegetais silvestres que crescem principalmente como plantas daninhas (> 50%) e que também são medicinalmente importantes nas comunidades rurais da região de Sargodha, Paquistão. Por meio de diferentes pesquisas e entrevistas com informantes-chave, foram coletados dados sobre percepção, coleta, preparação e uso de 40 vegetais silvestres, pertencentes a 27 famílias. A família de ocorrência silvestre mais comum foi a Cucurbitaceae. As plantas mais frequentemente utilizadas foram as ervas, seguidas de árvores e arbustos. De acordo com o modo de consumo, a maioria das plantas é cozida, enquanto outras são usadas na forma de saladas, enquanto sucos, temperos, picles, forma crua (suas partes como frutas), geleias, etc. também são usados. As partes de plantas mais comumente usadas foram frutas seguidas de brotos e folhas. De acordo com a visão medicinal dos vegetais silvestres coletados, a maioria das plantas é utilizada para distúrbios gastrintestinais. O presente estudo confirma a descoberta de que as comunidades rurais colhem plantas silvestres comestíveis, sobretudo plantas daninhas, como uma estratégia de sobrevivência. Ele apresenta os dados de base sobre o uso de recursos vegetais, como vegetal comestível silvestre, pelas comunidades nativas da área. Além disso, muitas plantas medicinais em potencial devem ser o foco de pesquisas futuras, especialmente do ponto de vista fitoquímico, para impulsionar as indústrias farmacêuticas.

ABSTRACT: This preliminary study provides the traditional consumption of wild vegetables that mostly grow as weeds (>50%) and that are also medicinally important in the rural communities of Sargodha region, Pakistan. Through different surveys and interviews with key informants, data on perception, gathering, preparation and use of 40 wild vegetables belonging to 27 families were collected. Most common wild occurring family was Cucurbitaceae. The most of the plants found were from herbs followed by trees and shrubs. According to mode of consumption, majority of the plants are cooked while others are used as in salads form while juices, spices, pickles, raw form (their parts like fruits), jams etc. are also used. Most commonly used plant parts were fruits followed by shoots and leaves. According to medicinal view of collected wild vegetables, most of the plants are used for gastrointestinal disorders. The present study confirms the findings that the rural communities can harvest wild edible plants especially weeds as a survival strategy. It presents the baseline data on the use of plant resources as wild edible vegetables by the native communities of the area. Moreover, many potential medicinal plants should be the focus of future research, especially from the phytochemical point of view for boosting pharmaceutical industries.

Abstract Background: Panic disorder has long been associated with the changes in various neurotransmitters, such as Neuropeptide-S (NPS). Objective: In this study we aimed to determine whether there is a relationship between blood NPS levels and panic disorder. Methods: Twenty nine patients with panic disorder and thirty two healthy control subjects who were age and gender matched were enrolled to the study. Blood samples were taken from participants and plasma NPS levels were quantified by using an ELISA kit. Results: In the study group, median NPS blood level was 16.7 pg/mL and in the control group it was 32.5 pg/mL. There was a statistically significant difference (p = 0.021). Using receiver operating characteristics (ROC) curve, sensitivity and specificity of NPS blood level, for diagnosing panic disorder was calculated, and it was found 79.3% and 56.25% respectively (AUC:0.672, 95% CI: 0.540-0.787). Discussion: Malfunction at the NPS modulatory system in the cortical areas (which is causing excitations in brain areas, such as amygdala and hypothalamus) does not only increase anxiety symptoms and risk of panic disorder but also causes panic disorder patients to have lower plasma NPS levels than the control group. Therefore it can be argued that such malfunction can be treated with a systemic treatment. Baykan H et al. / Arch Clin Psychiatry. 2018;45(4):79-81

Abstract: Recently, there has been a remarkable increase in biomedical research being conducted in low and middle-income countries. This increase has brought attention to the need for high quality research ethics systems within these countries and a greater focus on research ethics training. Though most programs tend to concentrate on training individuals, less attention has focused on institutions as the target of such training. In this paper we demonstrate a rapid approach to evaluating institutional research capacity. The method adapts the Octagon Model, which evaluates institutional research ethics using eight domains: basic values and identity, organization of activities, implementation, relevance, proper skills, financing and administration, target groups, and working environment. The framework was applied to the University of Zambia in order to conduct a baseline assessment of university research ethics capacity. Internal and external assessments were conducted. The domains of working environment and proper skills scored highest, while relevance, target groups and identity scored lower. Consistent with previous work, a systems approach to evaluating institutional research development capacity can provide a rapid assessment of an institutional bioethics program. This case study reveals the strengths and weaknesses of the university’s research ethics program and provides a framework for future capacity growth.

Resumen: Recientemente, ha habido un notable aumento en la investigación biomédica en países de ingresos bajos y medianos. Este aumento ha llamado la atención sobre la necesidad de sistemas éticos de investigación de alta calidad en estos países y un mayor enfoque en la formación en ética de la investigación. Aunque la mayoría de los programas tienden a concentrarse en la formación de los individuos, menos atención se ha centrado en las instituciones como objetivo de dicha formación. En este trabajo se demuestra un enfoque rápido para evaluar la capacidad de investigación institucional. El método adapta el modelo Octagon, que evalúa la ética institucional de la investigación utilizando ocho dominios: valores básicos e identidad, organización de actividades, implementación, relevancia, habilidades adecuadas, financiamiento y administración, grupos objetivo y ambiente de trabajo. El marco se aplicó a la Universidad de Zambia, con el fin de realizar una evaluación inicial de la capacidad de ética de la investigación universitaria. Se realizaron evaluaciones internas y externas. Los ámbitos del entorno de trabajo y de las competencias apropiadas obtuvieron el puntaje más alto, mientras que la relevancia, los grupos objetivo y la identidad obtuvieron calificaciones más bajas. De acuerdo con trabajos previos, un enfoque sistémico para evaluar la capacidad de desarrollo institucional de la investigación puede proporcionar una evaluación rápida de un programa institucional de bioética. Este estudio de caso revela las fortalezas y debilidades del programa de ética de la investigación de la universidad y proporciona un marco para el futuro crecimiento de la capacidad.

Resumo Objetivos Terremotos são desastres naturais imprevisíveis e devastadores. Eles podem causar destruição em massa e morte, e os sobreviventes podem apresentar sintomas psicológicos severos. O objetivo deste estudo foi revisar estudos publicados nos últimos 20 anos pra compilar o conhecimento disponível acerca da ocorrência de transtorno do estresse pós-traumático (TEPT) após terremotos. A revisão também descreve outras complicações psiquiátricas que podem estar associadas a terremotos, oferecendo aos leitores um melhor entendimento geral sobre o assunto, e discute vários fatores sociodemográficos que podem estar associados com TEPT pós-terremoto. Métodos Foi realizada uma busca de literatura nas principais bases de dados, como MEDLINE, PubMed, EMBASE e PsycINFO, e também em revistas de neurologia e psiquiatria, e vários outros periódicos médicos. Os termos usados nas buscas eletrônicas incluíram, mas não se limitaram a, posttraumatic stress disorder (PTSD), posttraumatic symptoms, anxiety, depression, major depressive disorder, earthquake e natural disaster. As informações relevantes foram então utilizadas para determinar as relações entre terremotos e sintomas de estresse pós-traumático. Resultados A revisão revelou que o TEPT é a condição de saúde mental mais comum em sobreviventes de terremoto. Depressão maior, transtorno de ansiedade generalizada, transtorno obsessivo-compulsivo, fobia social e fobias específicas foram outras condições encontrados. Conclusão A prevalência de TEPT variou bastante. O transtorno foi dependente de múltiplos fatores de risco em populações-alvo e também do intervalo de tempo decorrido entre a exposição ao incidente fatal e a avaliação. As mulheres pareceram ser o grupo mais amplamente afetado, ao passo que idosos e crianças demonstração considerável impacto psicossocial.

Abstract Objectives Earthquakes are unpredictable and devastating natural disasters. They can cause massive destruction and loss of life and survivors may suffer psychological symptoms of severe intensity. Our goal in this article is to review studies published in the last 20 years to compile what is known about posttraumatic stress disorder (PTSD) occurring after earthquakes. The review also describes other psychiatric complications that can be associated with earthquakes, to provide readers with better overall understanding, and discusses several sociodemographic factors that can be associated with post-earthquake PTSD Method A search for literature was conducted on major databases such as MEDLINE, PubMed, EMBASE, and PsycINFO and in neurology and psychiatry journals, and many other medical journals. Terms used for electronic searches included, but were not limited to, posttraumatic stress disorder (PTSD), posttraumatic symptoms, anxiety, depression, major depressive disorder, earthquake, and natural disaster. The relevant information was then utilized to determine the relationships between earthquakes and posttraumatic stress symptoms. Results It was found that PTSD is the most commonly occurring mental health condition among earthquake survivors. Major depressive disorder, generalized anxiety disorder, obsessive compulsive disorder, social phobia, and specific phobias were also listed. Conclusion The PTSD prevalence rate varied widely. It was dependent on multiple risk factors in target populations and also on the interval of time that had elapsed between the exposure to the deadly incident and measurement. Females seemed to be the most widely-affected group, while elderly people and young children exhibit considerable psychosocial impact.

To change the recalcitrant nature of the lignocellulosic material for maximum hydrolysis yield, a comprehensive study was done by using sulphuric acid as an exclusive catalyst for the pretreatment process. The enzymatic digestibility of the biomass [Water Hyacinth: Eichhornia crassipes] after pretreatment was determined by measuring the hydrolysis yield of the pretreated material obtained from twenty four different pretreatment conditions. These included different concentrations of sulphuric acid (0.0, 1.0, 2.0 and 3.0%), at two different temperatures (108 and 121 ºC) for different residence times (1.0, 2.0 and 3.0h).The highest reducing sugar yield (36.65 g/L) from enzymatic hydrolysis was obtained when plant material was pretreated at 121 ºC for 1.0 h residence time using 3.0% (v/v) sulphuric acid and at 1:10 (w/v) solid to liquid ratio. The total reducing sugars obtained from the two-stage process (pretreatment + enzymatic hydrolysis) was 69.6g/L. The resulting sugars were fermented into ethanol by using Saccharomyces cerevisiae. The ethanol yield from the enzymatic hydrolyzate was 95.2% of the theoretical yield (0.51g/g glucose), as determined by GS-MS, and nearly 100% since no reducing sugars were detected in the fermenting media by TLC and DNS analysis.

Road traffic injury (RTI) is the leading cause of death in persons aged 10-24 worldwide and accounts for about 15% of all male deaths. The burden of RTI is unevenly distributed amongst countries with over eighty-fold differences between the highest and lowest death rates. Thus the unequal risk of RTI occurring in the developing world, due to many reasons, including but not limited to rapid motorization and poor infrastructure, is a major global challenge. This editorial highlights a number of key issues that must inform programs designed to prevent RTI in the developing world, where the epidemic is all the more insidious. Firstly, road safety is a development issue; secondly, road traffic injury is a major health issue; thirdly, road traffic injuries can be prevented by the implementation of scientific measures; fourthly, pre-hospital and hospital emergency care is needed; and fifthly, research on RTI is neglected in low-income and middle-income countries. The repercussion of such progress to Peru is also discussed.

Los traumatismos causados por el tránsito son la principal causa de muerte en personas de 10-24 años a nivel mundial y representan alrededor del 15% de todas las muertes en varones. La carga de enfermedad de los traumatismos causados por el tránsito está distribuida de manera desigual entre los países pues la tasa de mortalidad más alta es ochenta veces superior a las más baja. Existe una clara desigualdad en el riesgo de ocurrencia de traumatismos causados por el tránsito, siendo notoriamente mayor en los países en desarrollo. Esta desigualdad se constituye como un reto mundial importante y se debe, aunque no sean los únicos factores, a muchas razones, incluyendo la rápida motorización y la pobre infraestructura. Este artículo hace énfasis en varios aspectos fundamentales cuya finalidad es informar a los programas diseñados para prevenir los traumatismos causados por el tránsito en los países en desarrollo, donde esta situación está más extendida. En primer lugar, la seguridad vial es un tema de desarrollo; en segundo lugar, los traumatismos causados por el tránsito constituyen un problema importante para la salud; en tercer lugar, los traumatismos causados por el tránsito pueden ser prevenidos mediante la implementación de medidas científicas adecuadas; en cuarto lugar, es necesaria la atención de emergencias hospitalarias y prehospitalarias; y, finalmente, la investigación en los traumatismos causados por el tránsito está relegada en los países de ingresos bajos y medios. Se discute además la repercusión de estos avances para el Perú.
