FUNCTIONAL OUTCOME FOLLOWING BI-COLUMNAR PLATING OF AO-TYPE 13C DISTAL HUMERUS FRACTURES.

Background: Intra articular fractures of the distal humerus are uncommon injuries and present the most difficult challenge among fractures of the distal end of the humerus. Objective of this study is to evaluate the functional outcome following bicolumnar plating of AO-Type 13C distal humerus fractures. A total of 20 int Materials and Methods: ra articular (AO TYPE C) distal humerus fractures were operated within a period of 2 years in KVG medical college and hospital Sullia were included in the study in which there were 12 males and 8 females.16 cases were due to RTA, 4 were due to self-fall, Out of 20 cases,1 (5%) was of AO C1 type of fracture, 16(80%) were of C2 and 3 (15%) were of C3 type of fractures. All the patients were operated with pre-countered distal humerus locking plates in orthogonal fashion and functional outcome was measured by Mayo's Elbow Performance Score (MEPS). In our series of 20 cases, the Results: average duration of the radiological union was 16±02 weeks. Excellent results were seen in 10, good in 6 and fair in 3, and poor in 1 According to Mayo's Elbow Performance Score (MEPS) at the end of 12 months follow up. Open reduct Conclusion: ion and internal fixation with bicolumnar plating is the ideal fixation for AO 13 type C distal humerus fractures. Use of locking plates, stable fixation, along with early elbow mobilization influence the final functional outcome. Bicolumnar plating provides better stability, allows early elbow range of motion and prevents elbow stiffness.

Antibiotic prescription patterns in paediatric wards of Rivers State university teaching hospital, southern Nigeria: a point prevalence survey

Antimicrobial resistance remains a threat to patient safety and healthcare outcomes and largely arises from inappropriate antimicrobial prescriptions. This study aimed to determine the pattern of antibiotic prescriptions in the Paediatrics department of Rivers State University Teaching Hospital, Port Harcourt.Method:A point prevalence survey was conducted in the Paediatric wards and Special Care Baby Unit (SCBU) on 13 November 2021. Records of all children admitted before or at 8:00a.m. on the day of the survey were descriptively analysed using the protocol and web-based management system of the Global Point Prevalence Survey of Antimicrobial Consumption and Resistance, University of Antwerp.Results: The antibiotic prevalence in this study was 77.4%. The most common indication(s) for antibiotic use in SCBU was infection prophylaxis (81.3%) and in paediatric wards: Pneumonia, Ear Nose Throat and Soft tissue infections accounted for (23.1%) each. Third-generation cephalosporins and aminoglycosides were predominantly used in all wards and were empirical-based prescriptions. Regarding antibiotic quality indicators of prescriptions: In SCBU: 19 (90.5%) had indication(s) for antibiotics documented, 10 (46.7%) were guideline compliant, and 1 (4.8%) had documented review/stop date. In the paediatric medical and surgical wards, 17(85.0%) vs. 4(100%) had indication(s) for antibiotics documented, 6(30.0%) vs. 0(0%) were guideline compliant, and 1(5.0%) vs. 4(100.0%) had a review/ stop date.Conclusion:High prevalence of antibiotic use, suboptimal antibiotic quality indicators and absence of laboratory evidence for antibiotic prescriptions were observed in the paediatric units. There is a need to reorientate prescribers and institute strategic measures to improve antimicrobial stewardship

Chemical composition, in vitro larvicidal and antileishmanial activities of the essential oil from Citrus reticulata Blanco fruit peel / Composição química, atividades larvicida e leishmanicida in vitro do óleo essencial da casca do fruto de Citrus reticulata Blanco

Abstract Numerous studies have investigated the chemical composition and biological activities of essential oils from different Citrus species fruit peel, leaves and flowers. This paper aims to investigate the chemical composition, larvicidal and antileishmanial activities of essential oil from Citrus reticulata fruit peel (CR-EO). CR-EO was obtained by hydrodistillation in a Clevenger-type apparatus and its chemical composition was analyzed by GC-MS and GC-FID. Limonene (85.7%), ɣ-terpinene (6.7%) and myrcene (2.1%) were identified as its major components. CR-EO showed high activity against promastigote forms of Leishmania amazonensis (IC50 = 8.23 µg/mL). CR-EO also exhibited high larvicidal activity against third instar Aedes aegypti larvae at a lethal concentration (LC50 = 58.35 µg/mL) and 100% mortality at 150 µg/mL. This study suggests, for the first time, the potential use of CR-EO against this important mosquito-borne viral disease caused by the genus Aedes.

An observational study on potential drug-drug interaction among hypertensive patients in a tertiary care hospital

Background: Drug-drug interactions are quite prevalent, especially in the geriatric population with comorbidities. It affects the effectiveness, safety, and tolerability of the medications they use. Aims and Objectives: This study aims to analyze and identify potential drug-drug interactions (pDDIs) in hypertensive patients using Medscape databases. Materials and Methods: A prospective and observational study was conducted in the Hypertension clinic of KMC, Chennai, for 3 months during November 2019–January 2020. Hypertensive patients of both sexes attending hypertension clinics with an age of more than 18 years and taking more than two antihypertensive drugs were included in the study. The use of Medscape databases enabled the appropriate data to be gathered and evaluated for pDDIs. Results: Three hundred patients in all were enrolled for the trial. One hundred and forty out of the 300 patients had pDDIs. Out of 140 patients, the majority (55%) were between the ages of 40 and 60. Males (56.4%) had a higher prevalence of pDDIs than females (43.6%). Atenolol, enalapril, and furosemide were the most frequently used medications in the present study that caused pDDIs, accounting for 29.8%, 19.5%, and 18.6%, respectively. Conclusion: The prevalence of pDDIs was found to be 46.6% overall, and an increase in comorbidities and polypharmacy were revealed to be important risk factors for the emergence of several pDDIs. Most of the antihypertensives were shown to interact frequently with calcium carbonate.

Prevalence of Hepatitis D Virus among People Attending the Antiretroviral Clinic and the Effect on the Liver Function Enzymes

Hepatitis D virus is an incomplete RNA virus requiring the assistance of the hepatitis B virus, specifically the HBsAg, to be infectious in humans. This study was designed to determine the prevalence of HDV among HIV patients and the effect on liver enzymes. The study was conducted at the Rivers state University Teaching hospital, Port Harcourt, Rivers State. Blood samples were obtained through vein puncture from 93 adults of which 41(44%) were males while 52(56%) were females between the ages 18 and 70 years attending the antiretroviral clinic and CD4+ cell count was also obtained. The samples were preserved at -20ºC. Each of the samples was tested using a SWE-Care rapid strip (China) for the presence of HBsAg. HDV antibody was detected using a Dia. Pro ELISA kit (Italy). The AST, ALT and ALP were determined. SPSS 21 was used to analyze the data and P values were determined. From the total samples collected, 7(7.5%) of them were positive to the HBsAg test of which 3(3.2%) were males, while 4(4.3%) of them were females. Of the 7 people positive to the HBsAg, 6(6.4%) were positive to the HDV antibody with 3(3.2%) females and 3(3.2%) males. There was significant depletion of the CD4+ cells across the groups. For the liver function test, the P values were ? 0.05 for AST, ALT and ? 0.05 for ALP. The HDV infection from the study was not gender, nor age based and suggests a negative impact on the CD4 cells. The liver function enzyme analysis, suggest higher risk of hypertension in HIV/HBV/HDV infection.

Epidemiology of Body Dysmorphic Disorder Among Adolescents In Imphal West District, Manipur

Background: Body Dysmorphic Disorder (BDD) is a psychiatric disorder characterized by preoccupa-tion with a perceived flaw(s) in one’s appearance, leads sufferers to engage in repetitive behaviours to try to hide or fix the flaw(s) causing significant distress and interference. BDD is an unrecognized and undiagnosed problem among adolescents. Therefore, conducting a study in the Imphal West will identify the adolescents at risk. The objective of the study is to determine the prevalence of BDD among higher secondary students in Imphal West, Manipur. Methodology: This study was conducted among higher secondary students during Aug 2019 -Feb 2020. Sampling was done by stratified two stage cluster design and self-administered validated Body Image Disturbance Questionnaire was used. Data were summarized using descriptive statistics. Chi-square test was used for comparing proportions. Results: Out of the total 1207 students, 52% were female. Almost 92.2% of the students were concerned about some aspect of their appearance. About 2.6% met the DSM-V criteria for BDD. Females were sig-nificantly dissatisfied with their skin (71.3%), nose (59.3%), hair (34.7%), whereas men with their mus-cle build (54.8%) and eyes (40.3%). Conclusions: The study revealed BDD was prevalent but many individuals were unaware about the condition and its treatment.

A RETROSPECTIVE STUDY OF CORRELATION BETWEEN DEPTH OF MALIGNANT TONGUE ULCER AND CERVICAL METASTASIS

BackgroundIn India, the oral tongue cancer is the fourth most common type of cancer among all cancers andsecond most common in cancers of oral cavity in males. Though there are advances in thediagnosis and treatment of the oral malignancies including the tongue, the failure rates in cancerof the oral tongue are high as the tongue malignancy has higher chances of spreading to necklymph nodes compared with other oral cancers.MethodA retrospective review of the case records of 55 patients who underwent surgery for thetreatment of carcinoma of the tongue was carried off in the department of General Surgery andOnco-surgery at the GCS Hospital, Ahmedabad to ensure the pattern of cervical lymph nodemetastasis and to assess the sensitivity of depth of malignant tongue ulcer in predicting its nodalspread.ResultsAmong 55 patients, diagnosed with carcinoma tongue and operated for hemi glossectomy alongwith MRND, Lymph node metastasis was present in 22 (40%). Out of these 22 patients, themean depth of invasion was 11 mm. In patients without lymph node metastasis, the mean depthof invasion was 8.3 mm.Chances of cervical lymph node metastasis increases with increment in the depth of malignanttongue ulcer.ConclusionThe infiltration depth of the malignant tongue ulcer can be used as an autonomous predictor forthe presence of nodal metastasis.

Determinants of Blood Pressure Control among Hypertensive Patients Attending a Rural Teaching Hospital in Southern Nigeria

Hypertension (HTN) is the commonest cardiovascular risk factor in sub-Saharan Africa. It is a global public health threat, often associated with significant morbidities and mortality with rising prevalence both in rural and semi-urban areas of economically disadvantaged countries. Aim: This study aimed to assess the determinants of blood pressure control among patients with hypertension receiving care at the Irrua Specialist Teaching Hospital in Southern Nigeria. Patients and Methods: A cross-sectional study of 502 consenting hypertensive adults receiving care at the Irrua Specialist Teaching Hospital, Irrua in Edo State, South-south Nigeria. A pre-tested semi-structured interviewer-administered questionnaire was used to collect data which was analyzed using SPSS version 21 and the level of significance was set at P < 0.05. Results: Five hundred and two participants (226 males, 276 females) completed the study with a mean age of 52.98 ± 12.82 years. Optimal blood pressure control was found in 15.5% of the study participants. Blood pressure control was significantly associated with being married (OR 1.549, CI: 1.040­2.309), having a monthly household income of over N50,000 (OR 1.691, CI: 0.999-2.863), engaging in physical activity (OR = 1.537, CI: 0.989-2.388), and not being obese evidenced by a normal Waist Hip Ratio (OR = 2.276, CI: 1.555-3.332). Conclusion: Blood pressure control to target goal was low in the study population and achieved only in less than one­fifth of respondents on antihypertensive therapy. Numerous socio-demographic and lifestyle variables were shown to be associated with blood pressure control. Physicians should emphasize medication adherence and lifestyle modification approaches in hypertensive adults.

In silico detection and characterization of novel virulence proteins of the emerging poultry pathogen Gallibacterium anatis

The pathogen Gallibacterium anatis has caused heavy economic losses for commercial poultry farms around the world. However, despite its importance, the functions of its hypothetical proteins (HPs) have been poorly characterized. The present study analyzed the functions and structures of HPs obtained from Gallibacterium anatis (NCTC11413) using various bioinformatics tools. Initially, all the functions of HPs were predicted using the VICMpred tool, and the physicochemical properties of the identified virulence proteins were then analyzed using Expasy's ProtParam server. A virulence protein (WP_013745346.1) that can act as a potential drug target was further analyzed for its secondary structure, followed by homology modeling and three-dimensional (3D) structure determination using the Swiss-Model and Phyre2 servers. The quality assessment and validation of the 3D model were conducted using ERRAT, Verify3D, and PROCHECK programs. The functional and phylogenetic analysis was conducted using ProFunc, STRING, KEGG servers, and MEGA software. The bioinformatics analysis revealed 201 HPs related to cellular processes (n = 119), metabolism (n = 61), virulence (n = 11), and information/storage molecules (n = 10). Among the virulence proteins, three were detected as drug targets and six as vaccine targets. The characterized virulence protein WP_013745346.1 is proven to be stable, a drug target, and an enzyme related to the citrate cycle in the present pathogen. This enzyme was also found to facilitate other metabolic pathways, the biosynthesis of secondary metabolites, and the biosynthesis of amino acids.

Hashtag bone: detrimental effects on bone contrast with metabolic benefits one and five years after Roux-en-Y gastric bypass

Bone loss is a potential adverse consequence of rapid and sustained weight loss after bariatric surgery. The aim of the present study was to evaluate the bone mass, body fat distribution, and metabolic parameters in women submitted to Roux-en-Y gastric bypass (RYGB). The study included the following three groups: one group of lean women (control [C] group) and two groups of obese women, one evaluated one year (B1) and the other five years (B5) after RYGB. Dual-energy X-ray absorptiometry and magnetic resonance imaging were used to determine bone mineral density (BMD; lumbar spine, total hip, and femoral neck) and abdominal fat content (subcutaneous [SAT] and visceral [VAT] adipose tissues, and intrahepatic lipids [IHL]). The BMD/body mass index ratio was lower in the B5 compared with the C group at all sites. Serum C-terminal telopeptide of type I collagen (CTX) levels were higher in the B1 and B5 groups compared with the C group. Individuals submitted to RYGB showed greater SAT but similar VAT and IHL values compared with those in the C group. However, the B5 group had higher mean parathyroid hormone levels compared with the other two groups. Individuals submitted to RYGB presented increased levels of CTX and low BMD for body weight than those in the C group, suggesting that bone catabolism is a persistent alteration associated with RYGB. In conclusion, the long-lasting metabolic benefits obtained with RYGB in obesity are counterbalanced by a persistent catabolic effect of the procedure on bone and mineral metabolism.

Prevalence of symptomatic urinary tract infection and bacterial spectrum of diabetic and non-diabetic patients at the two teaching hospitals in Enugu, Nigeria

Background: Diabetes mellitus is a group of metabolic disorder characterized by relative or absolute lack of insulin. When this condition is not properly managed, it can lead to complications that make diabetic patients vulnerable to urinary tract infections (UTI). The objectives of this study are to determine the prevalence of microbiologically confirmed UTI and the spectrum of uropathogens in diabetic and non-diabetic patients with clinical features of UTI attending the two tertiary hospitals in Enugu State, Nigeria. Methodology: Clean catch specimen of single mid-stream urine sample was collected from each of 60 (22 males, 38 females) diabetic and 60 (22 males, 38 females) non-diabetic patients enrolled using stratified random sampling method. The samples were cultured on standard microbiological culture media (MacConkey and Blood agar plates) and incubated aerobically at 37◦C for 24 hours. Plates with significant bacteria growth (>105 CFU/ml) were processed further for bacterial identification using conventional biochemical test scheme. Antibiotic susceptibility test (AST) of each isolate to 17 selected antibiotics was performed by the modified disc diffusion method. Results: Of the total 120 patients enrolled, 101 had bacterial pathogens isolated from their voided urine samples; 51 of 60 (85.0%) diabetics and 50 of 60 (83.3%) non-diabetics (p=0.802). Bacteria were isolated in 59.1% (13/22) of diabetic and 54.5% (12/22) of non-diabetic male patients compared to 100% (38/38) isolation rate in diabetic and non-diabetic female patients. The most frequently isolated bacteria in the diabetic patients were Proteus spp (18.6%), Klebsiella spp (16.9%) and Escherichia coli (15.5%) while the most frequently isolated bacteria among the non-diabetic patients were E. coli (30.0%), Proteus spp (26.3%) and Enterobacter spp (14.0%). Apart from Klebsiella spp which was more frequently isolated from the diabetic (16.9%) than non-diabetic patients (6%) (p=0.039), the frequency other bacterial pathogen isolation such as Proteus spp, E. coli, Enterobacter spp, Pseudomonas aeruginosa, Staphylococcus aureus and Enterococcus spp was not significantly different between the two population groups (p>0.05). The Gram-positive and Gram-negative bacteria were highly sensitive to imipenem in both diabetic and non-diabetic patients, but the isolates from both study groups exhibited low susceptibility to amoxicillin, nitrofuran- toin, cefixime and cefuroxime. Conclusion: Although the overall frequency of bacterial pathogen isolation in the diabetic and non-diabetic patients was not significantly different, females had a higher pathogen isolation rate than the males, and diabetic females had a higher frequency of polymicrobial infections compared to non-diabetic females and the male population. The high antimicrobial resistance of the isolated bacteria pathogens underscores the need for clinical microbiology laboratory testings to optimize the management of UTI in diabetic patients.

Is birth weight associated with pregestational maternal BMI? BRISA Cohort, Ribeirão Preto, Brazil

Given the increase of women with excess weight or obesity and its possible effects on birth weight, the present study aimed to investigate the association between pregestational maternal body mass index (BMI) and birth weight in a birth cohort from Ribeirão Preto, SP, Brazil. This was a prospective study conducted on 1362 mother-child pairs involving singleton births. The women were evaluated using standardized questionnaires during the second trimester of pregnancy and at the time of childbirth. Information about the newborns was obtained from their medical records. The dependent variable was birth weight, categorized as low, adequate, or high. The independent variable was pregestational maternal BMI, categorized as malnutrition, adequate weight, overweight, and obesity. A multinomial regression model was used to estimate the crude and adjusted relative risk (RR) of low and high birth weight. A high frequency of pregestational excess weight (39.6%) was detected and found to be independently associated with high birth weight (RR=2.13, 95%CI: 1.19-3.80 for overweight and RR=3.34, 95%CI: 1.80-6.19 for obese pregnant women). There was no association between pregestational malnutrition and low birth weight (RR=1.70; 95%CI: 0.81-3.55). The present data showed a high rate of women with excess pregestational weight, supporting the hypothesis that pregestational BMI may contribute to high birth weight babies and indicating the need for actions aiming to prevent excessive weight in women at reproductive age.

Influence of the host diet on the performance of Doryctobracon areolatus (Hymenoptera: Braconidae) / Influência da dieta do hospedeiro na performance de Doryctobracon areolatus (Hymenoptera: Braconidae)

Abstract Fitness in parasitoids is generally influenced by host quality. We evaluated the development parameters of Doryctobracon areolatus (Hymenoptera: Braconidae) parasitoid on Anastrepha fraterculus (Diptera: Tephritidae) larvae, reared in artificial diets with different protein sources. Larvae of A. fraterculus were reared in the diets based on 1) raw wheat germ (control); 2) whole rice flour; 3) corn flour; and, 4) whole wheat flour + soybean meal. The larvae were used for the development of D. areolatus, to evaluate the number of offspring/female, emergence rate, sex ratio, egg-adult period, adult weight posterior tibia length and longevity. Larvae of A. fraterculus reared in the diets based on wheat germ and corn flour obtained a greater number of offspring, with shorter duration of egg-adult period for males and females. In diets with rice flour and corn flour, A. fraterculus larvae generated adults of D. areolatus with greater weight, longer tibia length and higher sex ratio, whereas larvae reared in wheat flour + soybean meal diet had a lower sex ratio. The diets based on rice flour and corn are the most appropriate for multiplication of the parasitoid.

Resumo O custo adaptativo de parasitoides é geralmente influenciado pela qualidade do hospedeiro. Nós avaliamos parâmetros de desenvolvimento do parasitoide Doryctobracon areolatus (Hymenoptera: Braconidae) em larvas de Anastrepha fraterculus (Diptera: Tephritidae) criadas em dieta artificial com diferentes fontes proteicas. Larvas de A. fraterculus foram criadas em dietas a base de: 1) germe de trigo cru (testemunha); 2) farinha de arroz integral; 3) farinha de milho; e, 4) farinha de trigo integral + farelo de soja. As larvas foram usadas para o desenvolvimento de D. areolatus para avaliar o número de descendentes/fêmea, taxa de emergência, razão sexual, duração do período ovo-adulto, peso de adultos, comprimento da tíbia posterior e longevidade. Larvas de A. fraterculus criadas nas dietas a base de germe de trigo e farinha de milho, permitiram obter um maior número de descendentes do parasitoide, com menor duração do período de desenvolvimento ovo-adulto, para ambos os sexos. Nas dietas com farinha de arroz e farinha de milho, larvas de A. fraterculus geraram adultos de D. areolatus com maior peso e tamanho de tíbia de machos e fêmeas e uma maior quantidade de fêmeas. A dieta contendo farinha de trigo + farelo de soja afetou a geração de descendentes, causando uma menor razão sexual. As dietas a base de farinha de arroz e milho são as mais adequadas para a multiplicação do parasitoide.

Parotid salivary mucocele in a companion rabbit (Oryctolagus cuniculus): a report on the clinical and laboratory characteristics and surgical treatment - case report / [Mucocele salivar parotídea em coelho doméstico (Oryctolagus cuniculus): relato de características clínico-laboratoriais e tratamento cirúrgico - relato de caso]

The present report aimed to describe the main characteristics of the parotid salivary mucocele in an adult male rabbit, which presented with a painless fluctuating mass with fluid content. Owing to the need for repeated fluid drainage, surgical excision was the chosen mode of treatment. Preoperative evaluation included radiography and blood analysis. The patient underwent surgical excision of the affected gland. Inhalation anesthesia was maintained by means of isoflurane and the cardio-respiratory parameters were monitored throughout the surgery. A bipolar electrocautery was used to assist in the incision and polyglactin 910 and nylon were the suture materials used in the wound closure technique. Post-operative medications included analgesics, anti-inflammatory agents and antibiotics. Histopathology of the excised glandular tissue revealed a mixed inflammatory infiltrate, fibroblasts, hemorrhage and hyperemia. The observations in this case suggest that surgical excision of the affected gland is the treatment of choice for the management of mucocele in companion rabbits, which has already been identified for other animals. Periodic acid-reactive Schiff staining confirmed the diagnosis of salivary mucocele. The complementary investigations helped to rule out the differential diagnosis and indicated a favorable prognosis, in view of the fact that the case was successfully resolved without complications or recurrence.(AU)

O presente relato teve como objetivo descrever as principais características da mucocele salivar parotídea em um coelho macho adulto, que apresentou uma massa flutuante indolor e com um conteúdo líquido em seu interior. Devido à necessidade de repetidas punções deste fluido, optou-se pela excisão cirúrgica como forma de tratamento. A avaliação pré-operatória incluiu radiografias e análises sanguíneas. O paciente foi submetido ao tratamento cirúrgico com excisão da glândula afetada. A anestesia inalatória foi mantida com isoflurano e os parâmetros cardio-respiratórios foram monitorados durante a cirurgia. Um eletrocautério bipolar foi utilizado para auxiliar na incisão e os fios poliglactina 910 e nylon foram utilizados na técnica de sutura. As medicações pós-operatórias incluíram agentes analgésicos, anti-inflamatórios e antibióticos. A histopatologia do tecido glandular removido revelou infiltrado inflamatório misto, fibroblastos, hemorragia e hiperemia. As observações neste caso sugerem que a remoção cirúrgica da glândula afetada seja o tratamento de escolha no manejo da mucocele em coelhos de companhia, o que já vem sendo identificado para outros animais. A coloração do ácido periódico reativo de Schiff confirmou o diagnóstico da mucocele salivar. Os exames complementares ajudaram a excluir as doenças que fazem parte do diagnóstico diferencial e indicaram um prognóstico favorável, tendo em vista o fato que este caso foi resolvido com sucesso, sem complicações ou recorrência.(AU)

In Vitro Antioxidant And Anti-Inflammatory Activities Of Alchornea Cordifolia (SCHUMACH And Thonn.) Mull. Arg. And Antrocaryon Klaineanum Pierre Extracts

Objective: This study aims to evaluate the in vitro antioxidant, anti-inflammatory activities of the aqueous and hydroethanolic extracts recipe of Alchornea cordifolia and Antrocaryon klaineanum. A preliminary phytochemical screening was carried out. Methods: The total phenols content was determined by the Folin Ciocalteu reagent method, while the antioxidant activity of both extracts was characterized by the 2-2diphenyl-1-picrilhidrazil (DPPH) and β-carotene assays. The anti-inflammatory activity of the extracts was evaluated as the inhibition of Bovine Serum Albumin (BSA) denaturation and antiproteinase activity. Results: The aqueous extracts of Alchornea cordifolia and Antrocaryon klaineanum contained more polyphenols [270 mg Ascorbic acid equivalent (AAE)/g dry weight (dw)] than the hydroethanolic recipe extract (262.41 mg AAE/g dw) at the same concentration level. On the other hand, the aqueous and hydroethanolic recipe extract had the same radical scavenging activity with the antiradical power of 0.851 and 0.830, respectively. Similarly, the recipe extract had the same reducing activity with reducing the power of 94.2±2.03 mg EAA/g dw and 97.4±4.16 mg EAA/g dw for the aqueous and hydroethanolic recipe extract of Alchornea cordifolia and Antrocaryon klaineanum respectively. For the anti-inflammatory activity it was observed that both extracts possess the same activity as Diclofenac® with an IC50 of 50.21 μg/ml. The phytochemical screening of the extracts revealed the presence of alkaloids, flavonoids, carbohydrates, phenols and tannins, which may account for their activities. Conclusion: The plant recipe extract studied possess antioxidant and anti-inflammatory potentials, which may be beneficiary to its consumers.

Isolation and characterization of hydrocarbon-degrading bacteria from gas station leaking-contaminated groundwater in the Southern Amazon, Brazil / Isolamento e caracterização de bactérias degradadoras de hidrocarbonetos de água subterrânea contaminada por vazamentos em posto de combustível no sul da Amazônia, Brasil

Abstract Twenty-three hydrocarbon-degrading bacteria strains were isolated from gas station leaking-contaminated groundwater located in the Southern Amazon, Brazil. Based on hydrocarbon (diesel, hexadecane, benzene, toluene and xylene) degradation ability, two strains were selected for further study. The amplification and sequencing of the 16S rRNA gene showed that these two strains belonged to the genus Bacillus (Bacillus sp. L26 and Bacillus sp. L30). GC-MS analysis showed that strain L30 was the most effective in degrading n-alkane (C10-C27) from diesel after 7 days of cultivation in mineral medium. Both strains produced biosurfactants and showed emulsification activity, specially the strain L30. Alkane hydroxylase gene (group III), which is important for alkane biodegradation, was present in strains. As a result, this study indicated that these bacteria could have promising applications in hydrocarbon bioremediation.

Resumo Vinte e três linhagens bacterianas degradadoras de hidrocarbonetos foram isoladas de água subterrânea contaminada por vazamento em posto de combustível no sul da Amazônia, Brasil. Com base na habilidade de degradar hidrocarbonetos (diesel, hexadecano, benzeno, tolueno e xileno), duas linhagens foram selecionadas para estudos posteriores. A amplificação e sequenciamento do gene 16S rRNA demonstrou que essas linhagens pertencem ao gênero Bacillus (Bacillus sp. L26 and Bacillus sp. L30). Análises de GC-MS mostraram que a linhagem L30 foi mais eficiente em degradar n-alcanos (C10-C27) presentes no diesel, após 7 dias de cultivo em meio mineral. Ambas as linhagens produziram biossurfactantes e apresentaram atividade emulsificante, especialmente a linhagem L30. O gene alcano hidroxilase (grupo III), o qual é importante para degradação de alcanos, foram detectados nas linhagens. Como resultado, este estudo indicou que essas linhagens bacterianas podem ser promissoras se aplicadas em processos de biorremediação.
