Biochemical & Pharmacological evaluation of liver oils of selected deep sea sharks and chimaeras of the Indian EEZ

With a seacoast of 8,1 18 km, an exclusive economic zone (EEZ) of 2 million square km, and with an area of about 30,000 square km under aquaculture, lndia produces close to six million tonnes of fish, over 4 per cent of the world fish production. While the marine waters upto 50m depth have been fully exploited, those beyond, remain unexplored. There is an ever increasing demand for fishery resources as food. The coastal fishery resources of the country are dwindling at a rapid pace and it becomes highly imperative that we search for alternate fishery resources for food. The option we have is to hunt for marine fishery resources. Studies pertaining to proximate composition, amino acid and fatty acid composition are essential to understand the nutraceutical values of these deep sea fishery resources. The present study was aimed to carry out proximate composition of deep sea fishery resources obtained during cruises onboard the FORV Sarise Sampada, to identify fishery resources which have appreciable lipid content and thereby analyse the bioactive potentials of marine lipids, to study the amino acid profile of these fishery resources, to understand the contents of SPA, MUFA and PUFA and to calculate the n3/n6 fatty acid contents. Though the presence of nutraceuticals was identified in the marine fishery resources their use as potential food resources deserve further investigation. So the study were carried out to calculate the hepatosomatic indices of sharks & chimaeras and conduct biochemical characterisation of liver oils of Apristurus indicus, Cenlrophorus scalprams, Centroselachus crepidater, Neoharriotta raleighana, and Harriotta pinnata obtained during cruises onboard the FORV Sugar Sampada.Therapeutic use of shark liver oil is evident from its use for centuries as a remedy to heal wounds and fight flu (Neil er al. 2006). Japanese seamen called it 'samedava' or "cure all". Shark liver oil is being promoted worldwide as a dietary supplement to boost the immune system, fight infections, to treat cancer and to lessen the side effects of conventional cancer treatment. These days more emphasis is laid on the nutritive benefits of shark liver oils especially on the omega 3 polyunsaturated fatty acids ( PUFAs) (Anandan er al. 2007) and alkylglycerols (AKGs) (Pugliese er al. I998) contained in them due to the high rise of inflammatory disorders such as arthritis, asthma and neurodegenerative diseases like Alzheimer’s, Parkinson’s and Schizophrenia. So the present study also evaluate the pharmacological properties with respect to analgesic, anti-inflammatory, anti pyretic and anti-ulcer effects of four different liver oils of sharks belonging to the Indian EEZ and to identify the components of oil responsible for these activities.The analgesic and anti-inflammatory activities of liver oils from Neoharriotra raleighana (NR), Centrosymnus crepidater (CC), Apristurus indicus (AI), and Centrophorus sculpratus (CS) sharks caught from the Arabian Sea and the Indian Ocean were compared. The main objectives also include determination of the cholesterol lowering effects of liver oils of Neoharriotra raleighana (NR) and Centrophorus sculpratus (CS) on the high fat diet induced dyslipidemia and to compare the impact of four isolipidemic diets, on levels of serum diagnostic marker enzymes, on lipid profile of blood and liver and antioxidant status of heart in male Albino rats. And also to study the efficacy of Centrophorus sculpratus (CS) liver oil against Complete Freund’s Adjuvant-induced arthritis and to compare the anti-inflammatory activity of this oil with a traditionally used anti-inflammatory substance gingerol (oleoresin extracted from ginger.). The results of the present study indicated that both (Centrophorus sculpratus liver oils as well as gingerol extracts proved to be effective natural remedies against CFA-induced arthritis in Albino rats.

Objetivo: Caracterizar la accidentalidad laboral en una clínica de tercer nivel de la ciudad de Bogotá, en el periodo 2010 a 2013. Materiales y Métodos: Se realizó un estudio de tipo corte transversal, utilizando una base de datos de accidentalidad en los trabajadores vinculados directamente con la institución. Resultados: Durante el periodo estudiado se generaron 191 accidentes, 57 casos en el año 2013, el personal de enfermería fue el grupo con mayor porcentaje de accidentes (70.2 %). El sitio donde ocurrieron con mayor frecuencia los accidentes fueron las áreas asistenciales (49.2 %). Al analizar los datos de los accidentes de riesgo biológico se encontró que el pinchazo es el más común (84.7%), seguido de las heridas abiertas y lesiones superficiales (77.2%). Las partes del cuerpo más frecuentemente lesionadas fueron extremidades superiores, siendo la mano la zona más afectada (60.2%); además identifica al paciente fuente del accidente en el 71.8% de los casos y no se logra determinar en un alto porcentaje, si el trabajador afectado usa elementos de protección personal al momento del evento (82.1%). Conclusiones Los accidentes de trabajo con exposición a riesgo biológico son frecuentes en los trabajadores del área asistencial, en especial en el personal de enfermería, dadas las características propias de sus tareas diarias y el cumplimiento de las mismas. El pinchazo fue causa más común, y la parte del cuerpo más frecuentemente afectada fueron las extremidades superiores, específicamente las manos. Dado que los accidentes laborales a riesgo biológico tienen el potencial de general consecuencias nocivas para la salud es esencial establecer estrategias tendientes a minimizar su frecuencia y severidad, por lo que se recomienda revisar e implementar nuevas tecnologías para la reducción de accidentes con elementos corto punzantes, aumentar la sensibilización de los trabajadores con respecto al uso de los elementos de protección personal y revisar la metodología utilizada para la investigación de accidentes laborales.

Effects of the basic fibroblast growth factor and its anti-factor in the healing and collagen maturation of infected skin wound

PURPOSE: The infection is one of the main factors that affect the physiological evolution of the surgical wounds. The aim of this work is to evaluate the effects of fibroblast growth factor (FGFâ) and anti-FGFâ in the healing, synthesis and maturation of collagen when topically used on infected skin wounds of rats. METHODS: An experimental study was perfomed in 60 male Wistar rats. All animals were divided in two groups (A and B). Each group was divided in three subgroups A1, B1; A2, B2 and A3, B3. After anesthesia with pentobarbital, two open squared wounds (1cm2), 4cm distant to each other, were done in the dorsal skin of all the rats. In group A (n=30) the wounds were contaminated with multibacterial standard solution, and in group B(n=30) the wounds were maintained sterile. These wounds were named F1 (for inflammation analysis) and F2 (for collagen study). The open wounds of A1 and B1 rats were topically treated with saline solution, A2 and B2 were treated with FGFâ and subgroups A3 and B3 were treated with FGFâ and anti-FGFâ. The rats were observed until complete epitelization of F2 wounds for determination of healing time and the expression of types I and III collagen, using Picro Sirius Red staining. Inflammatory reaction in F1 wounds was studied using hematoxilineosin staining. The three variable was measured by the Image Pro-Plus Média Cybernetics software. The statistical analysis was performed by ANOVA and Tukey test, considering p<0.05 as significant. RESULTS: It was observed that infection retarded significantly (p<0.05) the time of wound scarring and the topical application of FCFb reverted the inhibition of healing caused by bacteria. The inflammatory reaction was greater in the subgroup B2 than in B1 and A3, and the difference was significant (p<0.05). It was observed greater expression of type I collagen in all the subgroups treated with FCFb, when compared with the untreated subgroups. Type III collagen was significantly decreased in wounds of B3 rats, comparing to the other subgroups. CONCLUSIONS: The FCFb accelerated the healing of open infected wounds and contributed with maturation of collagen, enhancing the type I collagen density. The anti-FCFb antibody was able to attenuate the production of both type I and III collagen

Trauma em idosos atendidos pelo serviço pré-hospitalar móvel

O The aim of this study was to characterize the occurrence of trauma in the elderly population served by the mobile pre-hospital service, in Natal, Rio Grande do Norte. This is a descriptive, transversal and quantitative approach and whose population consisted of 2,080 trauma victims. The sample, of systematic random type, consisted of 400 elderly people, aged from 60 years old, assisted by the Office of Mobile Emergency in Natal / RN, between January 2011 and December 2012. Data collection began after consent and assent of the institution of a Research Ethics Committee under No. 309 505. It was proceeded to documentary retrospective analysis of records of this service through a form of self-development, validated by expert judges considered reliable (α> 0.75) and valid (CVI = 0.97) in their clarity and relevance. Data were tabulated by the Statistical Package for Social Sciences, version 20.0. The results show that older victims have an average age of 74.19 years old, with a prevalence of female involvement by chronic diseases, especially hypertension, average usage of 2.2 routine medications with vital signs within normal limits. The trauma prevailed during the daytime, in the residence of the victims, north of the city and on weekends. Among the mechanisms of trauma were falls, traffic accidents and physical aggression, whose most common type was brain-cerebral trauma and the main consequences were suture wounds and closed fractures. Basic Support Units were as more driven to pre-hospital care (87.8%) and the main destination place consisted of a referral hospital for emergency of the state (57.5%). Among the most commonly performed procedures by nursing staff immobilization with rigid board and neck collar and the peripheral venipuncture, and the main component used for volume replacement to saline were highlighted. There was a significant relationship between the deaths and the mechanism of injury, mechanism of injury and procedures, except medication administration procedures carried out, except immobilization and unit for service. It is highlighted the prevalence of trauma in the elderly, poor follow-up Pre-Hospital Trauma Life Support protocol and the paucity of records and nursing procedures performed. There is need for a protocol of care specific to elderly trauma victims and education strategies for the prevention of such events

Topical effect of propolis in the repair of sulcoplasties by the modified Kazanjian technique. Cytological and clinical evaluation.

A study was conducted to analyze the effects of propolis mouth rinse on the repair of surgical wounds after sulcoplasty by the modified Kazanjian technique. Twenty-seven patients who underwent sulcoplasty were divided into three groups: C1--patients who did not use the mouth rinse C2--patients who used a mouth rinse containing 5% aqueous alcohol T--patients who used a mouth rinse containing 5% propolis in aqueous alcohol solution. The patients returned 7, 14, 30, and 45 days after surgery for cytological and clinical evaluation. It was concluded that: 1) the mouth rinse containing propolis in aqueous alcohol solution aids repair of intra-buccal surgical wounds and exerts a small pain-killing and anti-inflammatory effect; 2) the vehicle employed has a minor irritant effect on intra-buccal surgical wounds; 3) exfoliative cytology allows epithelization of intrabuccal surgical wounds.

Stressful life events and occupational accidents

Objective: The purpose of this study was to examine the association between stressful life events and occupational accidents. Methods: This was a population-based case-control study, carried out in the city of Botucatu, in southeast Brazil. The cases consisted of 108 workers who had recently experienced occupational accidents. Each case was matched with three controls. The cases and controls answered a questionnaire about recent exposure to stressful life events. Results: Reporting of environmental problems, being a victim of assault, not having enough food at home and nonoccupational fatigue were found to be risk factors for work-related accidents with estimated incidence rate ratios of 1.4 [95% confidence interval (95% CI) 1.1-1.7], 1.3 (95% CI 1.1 1-1.7), 1.3 (95% CI 1.1-1.6), and 1.4 (95% CI 1.2-1.7) respectively. Conclusions: The findings of the study suggested that nonwork variables contribute to occupational accidents, thus broadening the understanding of these phenomena, which can support new approaches to the prevention of occupational accidents.

Incidência de empiema pleural nos ferimentos tóraco-abdominais

OBJETIVO: Os ferimentos penetrantes com comprometimento simultâneo das cavidades torácica e abdominal (FTA), além da dificuldade diagnóstica, merecem especial atenção em relação à conduta adotada para o tratamento do espaço pleural. O objetivo do presente estudo foi identificar os principais fatores relacionados à incidência de empiema pleural em pacientes com ferimentos penetrantes localizados na transição toracoabdominal. MÉTODO: Utilizando-se o modelo estatístico de regressão logística múltipla, os autores analisaram 110 pacientes com ferida toracoabdominal penetrante, submetidos à drenagem pleural fechada e laparotomia. A complicação empiema pleural foi estudada quanto à incidência e fatores envolvidos. Considerou-se o nível alfa igual a 0,05. RESULTADOS: Do total, 91 (82,7%) pacientes eram do sexo masculino e 19 (17,3%) do feminino. A faixa etária situou-se entre 13 e 63 anos. Os FTA foram causados por projétil de arma de fogo em 60 casos (54,5%) e por arma branca em 50 casos (45,5%). O empiema pleural incidiu em quatro (3,6%) dos pacientes estudados. Na análise estatística a incidência de empiema pleural esteve relacionada com: lesão de víscera oca (OR=3,1386, p=0.4005); lesão do lado esquerdo do diafragma (OR= 12,98, p=0,1178) e choque hemorrágico à admissão (OR=23,9639, p=0,0250). CONCLUSÕES: A chance da ocorrência de empiema pleural foi cerca de três vezes maior em pacientes com lesão de víscera oca e, de 13 vezes se a esta lesão estava associada à lesão do lado esquerdo do diafragma; aumentando para 24 vezes se estes pacientes apresentavam, concomitantemente, estado de choque hemorrágico à admissão.

Experimental Basis and New Insights for Cell Therapy in Chronic Obstructive Pulmonary Disease

Chronic Obstructive Pulmonary Disease (COPD) can be briefly described as air flow limitation and chronic dyspnea associated to an inflammatory response of the respiratory tract to noxious particles and gases. Its main feature is the obstruction of airflow and consequent chronic dyspnea. Despite recent advances, and the development of new therapeutic, medical and clinical approaches, a curative therapy is yet to be achieved. Therapies involving the use of tissue-specific or donor derived cells present a promising alternative in the treatment of degenerative diseases and injuries. Recent studies demonstrate that mesenchymal stem cells have the capacity to modulate immune responses in acute lung injury and pulmonary fibrosis in animal models, as well as in human patients. Due to these aspects, different groups raised the possibility that the stem cells from different sources, such as those found in bone marrow or adipose tissue, could act preventing the emphysematous lesion progression. In this paper, it is proposed a review of the current state of the art and future perspectives on the use of cell therapy in obstructive lung diseases.

Utilization of fringe projection technique for evaluation of wound dimensions and of healing progress.

Background: The methods used for evaluating wound dimensions, especially the chronic ones, are invasive and inaccurate. The fringe projection technique with phase shift is a non-invasive, accurate and low-cost optical method. Objective: The aim is to validate the technique through the determination of dimensions of objects of known topography and with different geometries and colors to simulate the wounds and tones of skin color. Taking into account the influence of skin wound optical factors, the technique will be used to evaluate actual patients’ wound dimensions and to study its limitations in this application. Methods: Four sinusoidal fringe patterns, displaced ¼ of period each, were projected onto the objects surface. The object dimensions were obtained from the unwrapped phase map through the observation of the fringe deformations caused by the object topography and using phase shift analysis. An object with simple geometry was used for dimensional calibration and the topographic dimensions of the others were determined from it. After observing the compatibility with the data and validating the method, it was used for measuring the dimensions of real patients’ wounds. Results and Conclusions: The discrepancies between actual topography and dimensions determined with Fringe Projection Technique and for the known object were lower than 0.50 cm. The method was successful in obtaining the topography of real patient’s wounds. Objects and wounds with sharp topographies or causing shadow or reflection are difficult to be evaluated with this technique.
