Up-regulation of GINS1 highlighted a good diagnostic and prognostic potential of survival in three different subtypes of human cancer / A regulação positiva de GINS1 destacou um bom potencial diagnóstico e prognóstico de sobrevivência em três subtipos diferentes de câncer humano

Abstract Cancer is a fatal malignancy and its increasing worldwide prevalence demands the discovery of more sensitive and reliable molecular biomarkers. To investigate the GINS1 expression level and its prognostic value in distinct human cancers using a series of multi-layered in silico approach may help to establish it as a potential shared diagnostic and prognostic biomarker of different cancer subtypes. The GINS1 mRNA, protein expression, and promoter methylation were analyzed using UALCAN and Human Protein Atlas (HPA), while mRNA expression was further validated via GENT2. The potential prognostic values of GINS1 were evaluated through KM plotter. Then, cBioPortal was utilized to examine the GINS1-related genetic mutations and copy number variations (CNVs), while pathway enrichment analysis was performed using DAVID. Moreover, a correlational analysis between GINS1 expression and CD8+ T immune cells and a the construction of gene-drug interaction network was performed using TIMER, CDT, and Cytoscape. The GINS1 was found down-regulated in a single subtypes of human cancer while commonly up-regulated in 23 different other subtypes. The up-regulation of GINS1 was significantly correlated with the poor overall survival (OS) of Liver Hepatocellular Carcinoma (LIHC), Lung Adenocarcinoma (LUAD), and Kidney renal clear cell carcinoma (KIRC). The GINS1 was also found up-regulated in LIHC, LUAD, and KIRC patients of different clinicopathological features. Pathways enrichment analysis revealed the involvement of GINS1 in two diverse pathways, while few interesting correlations were also documented between GINS1 expression and its promoter methylation level, CD8+ T immune cells level, and CNVs. Moreover, we also predicted few drugs that could be used in the treatment of LIHC, LUAD, and KIRC by regulating the GINS1 expression. The expression profiling of GINS1 in the current study has suggested it a novel shared diagnostic and prognostic biomarker of LIHC, LUAD, and KIRC.

Resumo O câncer é uma doença maligna fatal e sua crescente prevalência mundial exige a descoberta de biomarcadores moleculares mais sensíveis e confiáveis. Investigar o nível de expressão de GINS1 e seu valor prognóstico em cânceres humanos distintos, usando uma série de abordagens in silico em várias camadas, pode ajudar a estabelecê-lo como um potencial biomarcador de diagnóstico e prognóstico compartilhado de diferentes subtipos de câncer. O mRNA de GINS1, a expressão da proteína e a metilação do promotor foram analisados ​​usando UALCAN e Human Protein Atlas (HPA), enquanto a expressão de mRNA foi posteriormente validada via GENT2. Os valores prognósticos potenciais de GINS1 foram avaliados por meio do plotter KM. Em seguida, o cBioPortal foi utilizado para examinar as mutações genéticas relacionadas ao GINS1 e as variações do número de cópias (CNVs), enquanto a análise de enriquecimento da via foi realizada usando DAVID. Além disso, uma análise correlacional entre a expressão de GINS1 e células imunes T CD8 + e a construção de uma rede de interação gene-droga foi realizada usando TIMER, CDT e Cytoscape. O GINS1 foi encontrado regulado negativamente em um único subtipo de câncer humano, enquanto comumente regulado positivamente em 23 outros subtipos diferentes. A regulação positiva de GINS1 foi significativamente correlacionada com a sobrevida global pobre (OS) de Carcinoma Hepatocelular de Fígado (LIHC), Adenocarcinoma de Pulmão (LUAD) e Carcinoma de Células Claras Renais de Rim (KIRC). O GINS1 também foi encontrado regulado positivamente em pacientes LIHC, LUAD e KIRC de diferentes características clínico-patológicas. A análise de enriquecimento de vias revelou o envolvimento de GINS1 em duas vias diversas, enquanto poucas correlações interessantes também foram documentadas entre a expressão de GINS1 e seu nível de metilação do promotor, nível de células imunes T CD8 + e CNVs. Além disso, também previmos poucos medicamentos que poderiam ser usados ​​no tratamento de LIHC, LUAD e KIRC, regulando a expressão de GINS1. O perfil de expressão de GINS1 no estudo atual sugeriu que é um novo biomarcador de diagnóstico e prognóstico compartilhado de LIHC, LUAD e KIRC.

Mutations in the bone morphogenetic protein 15 gene causing defective protein secretion in Cholistani infertile sheep / Mutações no gene da proteína morfogenética óssea 15 causadoras de defeitos na secreção proteica em ovelhas inférteis Cholistani

Naturally occurring mutations in morphogenetic protein 15 (BMP15) are associated with decreased ovulation rate (OR), litter size (LS), and sterility. It is of a great interest to elucidate BMP15 gene in Cholistani sheep breed to uplift socio-economic status and the knowledge of Cholistani sheep breeding in Southern Punjab, Pakistan. In our study, a total of 50 infertile Cholistani sheep aged between 2-6 years and having no blood relation were screened for BMP15 mutations. For this purpose, a high-quality DNA was extracted from the blood of sheep followed by primer designing, Polymerase Chain Reaction (PCR) amplification, DNA sequencing, and in silico analyses. Out of total 50 samples, 9 samples including case 1 (T3), case 2 (T8), case 3 (T17), case 4 (T22), case 5 (T25), case 6 (T33), case 7 (T40), case 8 (T44), and case 9 (T47) were found positive for a variety of already reported and novel BMP15 mutations. Further in silico analyses of the observed mutations have shown the functional impact of these mutations on different characteristics (molecular weight, theoretical PI, estimated half-life, instability index, sub-cellular localization, and 3D confirmation) of the encoded proteins, possibly altering the normal functionality. In a nutshell, findings of this study have confirmed the possible essential role of the BMP15 mutations in the infertility of the Cholistani sheep.

Mutações de ocorrência natural na proteína morfogenética 15 (BMP15) estão associadas à diminuição da taxa de ovulação (TO), tamanho da ninhada (TN) e esterilidade. Estudar a BMP15 na raça Cholistani para elevar o status socioeconômico e o conhecimento da criação de ovinos Cholistani no sul de Punjab, Paquistão. Em nosso estudo, 50 ovelhas Cholistani inférteis sem parentesco sanguíneo foram rastreadas para mutações BMP15. Para tanto, um DNA de alta qualidade foi extraído do sangue dessas ovelhas, seguido de concepção do primer, amplificação da reação em cadeia da polimerase (PCR), sequenciamento de DNA e análises in silico. Do total de 50 amostras, 9, incluindo caso 1 (T3), caso 2 (T8), caso 3 (T17), caso 4 (T22), caso 5 (T25), caso 6 (T33), caso 7 (T40), caso 8 (T44) e caso 9 (T47), foram consideradas positivas para uma variedade de mutações BMP15 novas e já relatadas. Mais análises in silico das mutações observadas mostraram o impacto funcional dessas mutações em diferentes características (peso molecular, PI teórico, meia-vida estimada, índice de instabilidade, localização subcelular e confirmação 3D) das proteínas codificadas, possivelmente alterando a funcionalidade normal. Nossos achados confirmaram o possível papel essencial das mutações BMP15 na infertilidade de ovelhas Cholistani.

Range of factors in the reduction of hyperhydricity associated with in vitro shoots of Salvia santolinifolia Bioss / Gama de fatores na redução da hiperidricidade associada a brotos in vitro de Salvia santolinifolia Bioss

Abstract Hyperhydricity is a serious physiological disorder and affects In vitro propagation of many plants and as well of Salvia santolinifolia. The donor material to initiate the in vitro culture was the callus taken from the in vitro shoots produced on Murashig and Skoogs (MS) medium at 4.0 mg/l BA. This callus formed numerous hyperhydric shoots on culturing upon the medium of the same composition. The aim was to systematically evaluate the effect of cytokinins (Benzyladnine (BA) and N6-(-2-isopentenyl) adenine (2iP), culture vessels magnitude, medium solidification, source of nitrogen and calcium chloride for the alleviation of hyperhydricity. In the tissue cultures of S. santolinifolia BA and 2iP induced severe hyperhydricity, when other factors i.e. culture vessels magnitude and a suitable concentration of agar, ammonium nitrate (NH4NO3), potassium nitrate (KNO3) & calcium chloride (CaCl2.2H2O) were not optimized. After 30 days' culture, we observed 83.82% hyperhydric shoots at increased level (1.5 mg/l 2iP) and 81.59% at decreased levels (1.0 mg/l 2iP). On the other hand, hyperhydricity percentage at decreased (0.4%) and at increased (0.8%) levels of agar were 72.37% and 39.08%, respectively. MS medium modification with NH4NO3 (412 mg/l), KNO3 (475 mg/l) and CaCl2.2H2O (880 mg/l) was found the best medium to reduced hyperhydricity (23.6%).

Resumo A hiperidricidade é um distúrbio fisiológico sério e afeta a propagação in vitro de muitas plantas e também da Salvia santolinifolia. O material doador para iniciar a cultura in vitro foi o calo retirado dos brotos in vitro produzidos em meio Murashig e Skoogs (MS) a 4,0 mg / l BA. Esse calo formou numerosos rebentos hiperídricos em cultura no meio da mesma composição. O objetivo foi avaliar sistematicamente o efeito das citocininas (Benziladnina (BA) e N6 - (- 2-isopentenil) adenina (2iP), magnitude dos vasos de cultura, solidificação do meio, fonte de nitrogênio e cloreto de cálcio para o alívio da hiperidricidade. culturas de tecidos de S. santolinifolia BA e 2iP induziram hiperidricidade severa, quando outros fatores, como magnitude dos vasos de cultura e uma concentração adequada de ágar, nitrato de amônio (NH4NO3), nitrato de potássio (KNO3) e cloreto de cálcio (CaCl2.2H2O), não foram otimizados. Após 30 dias de cultura, observamos 83,82% de brotos hiperídricos em níveis aumentados (1,5 mg / l 2iP) e 81,59% em níveis reduzidos (1,0 mg / l 2iP). Por outro lado, a porcentagem de hiperidricidade diminuiu (0,4%) e em níveis aumentados (0,8%) de ágar foram 72,37% e 39,08%, respectivamente. A modificação do meio MS com NH4NO3 (412 mg / l), KNO3 (475 mg / l) e CaCl2.2H2O (880 mg / l) foi encontrada melhor hiperidricidade média a reduzida (23,6%).

SUMMARY: The present work aimed to study the effect of replacing fish meal (FM) in the fish diet with shrimp by-product meal (SBM) on the growth performance parameters of the Nile Tilapia, Oreochromis niloticus. A total of 200 specimens of monosex O. niloticus fries were obtained from a private fish farm at Kafr El-Sheikh Governorate. They were transported to the fish laboratory at the Animal House of Zoology Department, Faculty of Science, Al-Azhar University. After two weeks for acclimation, the fish were divided into 5 groups, 2 replicates for each group (20 fish in each replicate). The five experimental diets were: C: control group with20 % fish meal (FM) and 0 % shrimp by-product meal (SM); T1, T2, T3, and T4 FM was replaced with SBM as 25 %, 50 %, 75 % and 100 %, respectively. Results indicated that the highest final length, growth in length, length gain, daily length gain and other growth performance parameters including the relationship between length and weight and condition factors of O. niloticus were recorded in T4 group (fed diet in which fish meal was completely replaced with shrimp by-product meal); while, their lowest values were recorded in control group. On the other hand, feed utilization parameters (feed intake, food conversion ratio, the maximum values of feed efficiency ratio and protein efficiency ratio) were recorded in T4 group and the minimum values were recorded in T3 group (fed diet in which 75 % of fish meal was replaced with shrimp by-product meal).

RESUMEN: El presente trabajo tuvo como objetivo estudiar el efecto de sustituir la harina de pescado (HP) en la dieta del pescado por harina de subproductos de camarón (HSC) sobre los parámetros de rendimiento de crecimiento de la Tilapia del Nilo, Oreochromis niloticus. Se obtuvieron un total de 200 especímenes de monosexo de O. niloticus de una piscifactoría privada en la gobernación de Kafr El-Sheikh. Fueron transportados al laboratorio de peces en el Departamento de Zoología de la Facultad de Ciencias, de la Universidad Al-Azhar. Después de dos semanas de aclimatación, los peces se dividieron en 5 grupos: Se realizaron dos repeticiones para cada grupo (20 peces en cada repetición). Las cinco dietas experimentales fueron: C: grupo control con 20 % de harina de pescado (HP) y 0 % de harina de subproductos de camarón (HSC); T1, T2, T3 y T4 FM se reemplazó con HSC con 25 %, 50 %, 75 % y 100 %, respectivamente. Los resultados indicaron que la longitud final más alta, el crecimiento en longitud, la ganancia de longitud, la ganancia de longitud diaria y otros parámetros de rendimiento del crecimiento, como además la relación entre la longitud y el peso, y los factores de condición de O. niloticus, se registraron en el grupo T4 (con una dieta reemplazada con harina de subproducto de camarón); mientras que, sus valores más bajos se registraron en el grupo control. Por otro lado, los parámetros de utilización del alimento (ingesta de alimento, índice de conversión de alimento, los valores máximos de índice de eficiencia alimenticia e índice de eficiencia proteica) se registraron en el grupo T4 y los valores mínimos se registraron en el grupo T3 (alimentación con dieta en la que el 75 % de la harina de pescado fue reemplazada por harina de subproductos de camarón).

Cutaneous leishmaniasis-Awareness, knowledge and practices among general population in rural and urban areas in Malakand region, Pakistan / Leishmaniose cutânea - conscientização, conhecimentos e práticas entre a população em geral nas áreas rurais e urbanas da região de Malakand, Paquistão

Abstract Malakand region is an endemic area for cutaneous leishmaniasis (CL). However, there are limited number of studies of this disease in Pakistan. Therefore, a study was conducted to understand the level of awareness attitude and practice among the residents of Makaland towards CL and the disease vectors. This study adopted a cross-sectional approach with a total of 400 respondents (n=93 rural and n= 307 urban). Overall, the population in Malakand region (61.2%) were well-informed in the role of sand fly in transmitting diseases, but most lack knowledge on the vector's behavior and almost a quarter (24.5%) were unable to provide knowledge on proper control measures. Alarmingly, the practice and attitudes of the general population was not satisfactory as close to half (49.8%) of the population did adopt any control method. This study calls for increase in awareness through health education campaign to reduce the risk of cutaneous leishmaniasis outbreaks in the future.

Resumo A região de Malakand é uma área endêmica para leishmaniose cutânea (CL). No entanto, há um número limitado de estudos sobre esta doença no Paquistão. Portanto, foi realizado um estudo para entender o nível de atitude e prática de conscientização entre os residentes de Makaland em relação aos CL e os vetores da doença. Este estudo adotou uma abordagem transversal com um total de 400 entrevistados (n = 93 rural e n = 307 urbano). No geral, a população da região de Malakand (61,2%) estava bem informada sobre o papel da mosca na transmissão de doenças, mas a maioria não possui conhecimento sobre o comportamento do vetor e quase um quarto (24,5%) foi incapaz de fornecer conhecimento sobre medidas de controle adequadas . De maneira alarmante, a prática e as atitudes da população em geral não foram satisfatórias, pois cerca da metade (49,8%) da população adotou algum método de controle. Este estudo apela ao aumento da conscientização por meio de campanhas de educação em saúde para reduzir o risco de surtos de leishmaniose cutânea no futuro.

Distribution of commensal rodents in some shops of three districts in Malakand region, Pakistan / Distribuição de roedores comensais em algumas lojas de três distritos na região de Malakand, Paquistão

Abstract Using wire mesh live traps distribution pattern of the Rattus rattus and Mus musculus in different shops of three districts of Malakand region, Pakistan were recorded from September 2014 to October 2015. Over all 103 rodents (Rattus rattus 86 and Mus musculus 17) were caught during in 0.04 trap success (2448 trap nights). Regression of daily captures on cumulative captures revealed an estimate of 103 rodents from all the sampled structures with an average of 3.55 rodents per shop. R. rattus; 83.4% of captures were numerically dominant in almost all types of shops sampled, and were significantly different than Mus musculus; 16.5% of captures. Both species were found together in some shops while they were mostly trapped from the separate shops. Male rodents outnumbered the females.

Resumo Usando o padrão de distribuição de armadilhas vivas de malha de arame do Rattus rattus e Mus musculus em diferentes lojas de três distritos da região de Malakand, o Paquistão foi registrado de setembro de 2014 a outubro de 2015. No total, 103 roedores (Rattus rattus 86 e Mus musculus 17) foram pegos durante em 0,04 armadilha de sucesso (2448 noites de armadilha). A regressão das capturas diárias em capturas cumulativas revelou uma estimativa de 103 roedores de todas as estruturas amostradas, com uma média de 3,55 roedores por loja. R. rattus; 83,4% das capturas foram numericamente dominantes em quase todos os tipos de lojas da amostra e foram significativamente diferentes do Mus musculus; 16,5% das capturas. Ambas as espécies foram encontradas juntas em algumas lojas, enquanto estavam na maior parte presas em lojas separadas. Os roedores machos eram mais numerosos do que as fêmeas.

Comparative brain analysis of wild and hatchery reared Mahseer (Tor putitora) relative to their body weight and length / Análise comparativa do cérebro de Mahseer (Tor putitora) selvagem e criado em incubatório em relação ao peso e comprimento corporal

Abstract The present study was aimed at comparing the brain size of mahseer (Tor putitora) in relation to their body weight and standard length, to investigate the potential impact of rearing environment on brain development in fish. The weight of the brain and three of its subdivisions cerebellum (CB), optic tectum (OT), and telencephalon (TC) were measured for both wild and hatchery-reared fish. The data was analysed using multiple analysis of covariance (MANCOVA), analysis of covariance (ANCOVA), and discriminate function analysis (DFA). We found the fish reared under hatchery conditions exhibit smaller brain size related to body weight, when compared to the wild ones. A significant (p<0.5) difference was observed in the length of CB and OT concerning the standard body length while no significant difference was found in TC of the fish from both the origins. The results of the current study highlight a logical assumption that neural deficiency affects the behaviour of fish, that's why the captive-reared fish show maladaptive response and face fitness decline when released to the natural environment for wild stock enhancement. The current study concluded that hatchery-reared fish exhibit variations in gross brain morphology as compared to their wild counterpart.

Resumo O presente estudo teve como objetivo comparar o tamanho do cérebro de mahseer (Tor putitora) em relação ao seu peso corporal e comprimento padrão, para investigar o impacto potencial do ambiente de criação no desenvolvimento do cérebro em peixes. O peso do cérebro e três de suas subdivisões — cerebelo (CB), tectum óptico (OT) e telencéfalo (TC) — foram medidos para peixes selvagens e criados em incubadoras. Os dados foram analisados usando análise múltipla de covariância (MANCOVA), análise de covariância (ANCOVA) e análise de função discriminante (DFA). Descobrimos que os peixes criados em condições de incubação apresentam menor tamanho do cérebro em relação ao peso corporal quando comparados aos selvagens. Uma diferença significativa (p <0,5) foi observada no comprimento do CB e OT em relação ao comprimento corporal padrão, enquanto nenhuma diferença significativa foi encontrada no CT dos peixes de ambas as origens. Os resultados do estudo atual destacam uma suposição lógica de que a deficiência neural afeta o comportamento dos peixes. É por isso que os peixes criados em cativeiro mostram uma resposta mal adaptativa e enfrentam declínio de aptidão quando liberados no ambiente natural para o aprimoramento do estoque selvagem. O estudo atual concluiu que os peixes criados em incubadoras exibem variações na morfologia cerebral bruta em comparação com suas contrapartes selvagens.

Greeen synthesis has been introduced as an alternative to chemical synthesis due to the serious consequences. Metal nanoparticles synthesized through green approach have different pharmaceutical, medical and agricultural applications. The present study followed a green and simple route for the preparation of potentially bioactive gold nanoparticles (Au NPs). Au NPs were prepared via green synthesis approach using crude basic alkaloidal portion of the tuber of Delphinium chitralense. The green synthesized Au NPs were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD) fourier transform infrared (FTIR), and UV-Visible spectrophotometer. Morphological analysis shows that Au NPs have cubic geometry with different sizes. UV-Vis spectroscopic analysis confirmed the synthesis of Au NPs while XRD proved their pure crystalline phase. The Au NPs showed promising dose dependent inhibition of both AChE and BChE as compared to the crude as well as standard drug.

A síntese verde foi introduzida como uma alternativa à síntese química devido às graves consequências. As nanopartículas metálicas sintetizadas através da abordagem verde têm diferentes aplicações farmacêuticas, médicas e agrícolas. O presente estudo seguiu uma rota verde e simples para a preparação de nanopartículas de ouro potencialmente bioativas (Au NPs). As NPs de Au foram preparadas via abordagem de síntese verde usando a porção alcaloide básica bruta do tubérculo de Delphinium chitralense. As NPs de Au sintetizadas verdes foram caracterizadas por microscopia eletrônica de transmissão (TEM), microscopia eletrônica de varredura (MEV), difração de raios X (DRX), infravermelho com transformada de Fourier (FTIR) e espectrofotômetro UV-Visível. A análise morfológica mostra que as NPs de Au possuem geometria cúbica com tamanhos diferentes. A análise espectroscópica UV-Vis confirmou a síntese de Au NPs enquanto a XRD provou sua fase cristalina pura.

@#The present study compares the in vitro effects of nanoparticles loaded pentamidine drug and conventional pentamidine on Leishmania tropica. Herein, pentamidine-loaded chitosan nanoparticles (PTN-CNPs) have been synthesized through an ionic gelation method with sodium tripolyphosphate (TPP). Next, the physical characteristics of PTN-CNPs were determined through the surface texture, zeta potential, in vitro drug release, drug loading content (DLC), and encapsulation efficacy (EE) and compared its efficacy with free pentamidine (PTN) drug against promastigotes and axenic amastigotes forms of L. tropica in vitro. The PTN-CNPs displayed a spherical shape having a size of 88 nm, an almost negative surface charge (-3.09 mV), EE for PTN entrapment of 86%, and in vitro drug release of 92% after 36 h. In vitro antileishmanial activity of PTN-CNPs and free PTN was performed against Leishmania tropica KWH23 promastigote and axenic amastigote using 3-(4, 5- dimethylthiazol-2-yl)-2, 5-diphenyletetrazolium bromide (MTT) assay. It was observed that the effect of PTN-CNPs and free PTN on both forms of the parasite was dose and time dependent. Free PTN presented low efficacy even at higher dose (40 µg/ml) with 25.6 ± 1.3 and 26.5 ±1.4 mean viability rate of the promastigotes and axenic amastigotes, respectively after 72 hrs incubation. While PTN-CNPs showed strong antileishmanial effects on both forms of parasite with 16 ± 0.4 and 19 ± 0.7 mean viability rate at the same higher concentration (40 µg/ml) after 72 hrs incubation. Half maximal inhibitory concentration (IC50) values of PTN-CNPs toward promastigotes and amastigotes were obtained as 0.1375 µg/ml and 0.1910 µg/ml, respectively. In conclusion, PTN-CNPs effectively inhibited both forms of the L. tropica; however, its effect was more salient on promastigotes. This data indicates that the PTN-CNPs act as a target drug delivery system. However, further research is needed to support its efficacy in animal and human CL.

Evaluation of fracture resistance of zirconia monolithic restorations: an in vitro study / Avaliação da resistência à fratura de restaurações monolíticas de zircônia: um estudo in vitro

Objective: was to evaluate fracture resistance of zirconia monolithic restorations after aging procedures. Material and methods: Monolithic translucent zirconia 3-unit FPDs were fabricated using Cerec inLab CAD/CAM system on 2 stainless steel dies with a uniform 120 degrees circumferential deep chamfer finish line of 1 mm width. FPDs were divided into 2 groups, first group (Group A) was subjected to aging procedures in an autoclave at hydrothermal conditions 134 oC /2 bars for 5 hours. Second group (Group B) was not subjected to any aging procedures (control group). All specimens of each group were loaded compressively in a universal testing machine at cross head speed 0.5 mm/min until fracture occurred. The percentage of monoclinic (m) phase was detected by XRD device. Scanning electron microscope (SEM) was used to examine the fractured surfaces for Aged TZI (Group A) and Non-aged TZI (Group B). Student's t-test was used to compare between fracture resistances of both groups. The significance level was set at P ≤ 0.05. Results: The fracture resistance mean (SD) values of non-aged TZI (Group B) was 2406.9 ± 306.8 N which showed statistically significantly higher than that of aged group (Group A) which was 1964.5 ± 234.5 N. The percentage of monoclinic (m) phase detected by XRD device software in non-aged TZI (Group B) was nearly 0 weight % and in aged TZI (Group A) was about 42 weight %. Conclusions:Accelerated artificial aging decreases the fracture resistance of monolithic TZI FPDs. (AU)

Agronomic efficiency and profitability of cotton on integrated use of phosphorus and plant microbes / Eficiência e rentabilidade agronômica do algodão no uso integrado de fósforo e micróbios vegetais

Cotton crop, plays a significant role in Pakistan's economy by ruling a prominent place in edible oil and local textile industry. Phosphorus (P) inaccessibility and deficiency of soil organic matter are the key restraints for low crop productivity in cotton. Therefore, a two years field study was designed during 2014-15, to explore the influence of phosphate solubilizing bacteria (PSB), farmyard manure (FYM), poultry manure (PM) and inanimate sources of P on various physiological, growth, yield and quality parameters of cotton crop at CCRI Multan. Field responses of seeds inoculated with two distinctive phosphate solubilizing bacteria (PSB) strains viz. S0 = control, S1 =strain-1, S2 = strain-2 and eight organic, inorganic P sources viz., P0= control, P1 = 80 kg ha-1 P from inorganic source, P2 = 80 kg ha-1 P from FYM, P3 = 80 kg ha-1 P from PM, P4 = 40 kg ha-1 P from FYM + 40 kg ha-1 P from inorganic source, P5 = 40 kg ha-1 P from PM + 40 kg ha-1 P from inorganic source, P6 = 80 kg ha-1 P from FYM + 40 kg ha-1 P from inorganic source, P7 = 80 kg ha-1 P from PM + 40 kg ha-1 P from inorganic source and P8 = 40 kg ha-1 P from FYM + 40 kg ha-1 P from PM were evaluated. Results revealed that inoculation of seeds with PSB and collective use of inorganic and organic sources of P had considerably increased the yield contributing attributes in cotton. However, the treatment P7 (80 kg P ha-1 from PM + 40 kg P ha-1 from inorganic source) in coincidence with seeds inoculated with PSB (S1) produced taller plant, maximum boll weight, significantly higher LAI and CGR. Significantly higher seed cotton yield, lint yield, fiber length and maximum BCR of 1.95 and 1.81 was also obtained from the P7 treatment during both crop-growing seasons. In conclusion, combined use of 80 kg P ha-1 from PM + 40 kg P ha-1 from inorganic source and cotton seeds inoculated with strain-1 improved phosphorus uptake ensuing in greater consumption of photo-assimilates for maximum growth and yield.

A safra de algodão, desempenha um papel significativo na economia do Paquistão, ao ocupar um lugar de destaque no óleo comestível e na indústria têxtil local. A inacessibilidade e a deficiência de fósforo (P) da matéria orgânica do solo são as principais restrições para a baixa produtividade das culturas em algodão. Portanto, um estudo de campo de dois anos foi desenvolvido durante 2014-15, para explorar a influência de bactérias solubilizantes de fosfato (PSB), esterco de capoeira (FYM), esterco de aves (PM) e fontes inanimadas de P sobre vários fatores fisiológicos, crescimento, rendimento e parâmetros de qualidade da cultura do algodão no CCRI Multan. Respostas de campo de sementes inoculadas com duas cepas distintas de bactérias solubilizantes de fosfato (PSB) viz. S0 = controle, S1 = cepa-1, S2 = cepa-2 e oito fontes orgânicas de P inorgânicas viz., P0 = controle, P1 = 80 kg ha-1 P de fonte inorgânica, P2 = 80 kg ha-1 P de FYM, P3 = 80 kg ha-1 P de PM, P4 = 40 kg ha-1 P de FYM + 40 kg ha-1 P de fonte inorgânica, P5 = 40 kg ha-1 P de PM + 40 kg ha-1 P de fonte inorgânica, P6 = 80 kg ha-1 P de FYM + 40 kg ha-1 P de fonte inorgânica, P7 = 80 kg ha-1 P de PM + 40 kg ha-1 P de fonte inorgânica e P8 = 40 Foram avaliados kg ha-1 P da FYM + 40 kg ha-1 P da PM. Os resultados revelaram que a inoculação de sementes com PSB e o uso coletivo de fontes inorgânicas e orgânicas de P aumentaram consideravelmente os atributos que contribuem para a produtividade no algodão. No entanto, o tratamento P7 (80 kg P ha-1 da PM + 40 kg P ha-1 da fonte inorgânica) em coincidência com sementes inoculadas com PSB (S1) produziu planta mais alta, peso máximo de cápsula, IAF e CGR significativamente maiores. Produtividade significativamente maior do algodão, rendimento de fiapos, comprimento da fibra e BCR máximo de 1,95 e 1,81 também foi obtida a partir do tratamento P7 durante as duas épocas de cultivo. Em conclusão, o uso combinado de 80 kg P ha-1 de PM + 40 kg P ha-1 de fonte inorgânica e sementes de algodão inoculadas com a cepa-1 melhoraram a captação de fósforo, resultando em maior consumo de foto assimilados para obter crescimento e produtividade máximos.
