Abstract The objective of this study was to conduct a systematic review and meta-analysis of relevant randomized control trials (RCTs) to determine the role of ibuprofen, as well as the optimum dose and duration of therapy, in preventing the incidence of heterotopic ossification (HO) after primary total hip arthroplasty (THA). A literature search was performed using the PubMed/MEDLINE and Cochrane Library databases for RCTs that compared the use of ibuprofen versus placebo as prophylaxis for HO in patients after THA. The main outcomes for this study were overall occurrence of HO, occurrence according to the Brooker classification, and gastrointestinal complications. A total of 27 potential articles were identified from the database. Eventually, four trials with 1,153 patients were included in the final analysis. When compared with placebo, the use of ibuprofen is associated with a reduction in the incidence of HO at the 3- and 12-month follow-up appointments, as well as the incidence of Brooker II and III HO (p < 0.05). However, there was no significant difference between the ibuprofen and placebo groups in terms of treatment discontinuation due to gastrointestinal complications or the incidence of Brooker I and IV HO (p > 0.05). The existing data indicates that ibuprofen is safe and efficacious in reducing the total incidence of HO along with Brooker II and III HO at follow-up. However, due to the small number of studies, the conclusions are limited; therefore, more high-quality clinical trials are required to develop guidelines for optimal dose and duration of therapy.

Resumo O objetivo deste estudo foi realizar uma revisão sistemática e metanálise de estudos clínicos randomizados (ECRs) relevantes para determinar o papel do ibuprofeno, sua dose ideal, e a duração do tratamento na prevenção de ossificação heterotópica (OH) após a artroplastia total primária do quadril (ATQ). Uma pesquisa bibliográfica foi feita nos bancos de dados PubMed/MEDLINE e Cochrane Library para a obtenção de ECRs quecomparassem ouso de ibuprofeno edeplacebo como profilaxiaparaOHem pacientes submetidos à ATQ. Os principais desfechos deste estudo foram ocorrência geral de OH, classificação de Brooker da OH, e complicações gastrintestinais. No total, 27 artigos foram identificados nos bancos de dados e 4 estudos, com 1.153 pacientes, foram incluídos na análise final. Em comparação ao placebo, o uso de ibuprofeno reduziu a incidência de OH aos 3 e 12 meses de acompanhamento e a incidência de OH Brooker II e III (p < 0,05). No entanto, não houve diferença significativa entre os grupos que receberam ibuprofeno e placebo em termos de interrupção do tratamento devido a complicações gastrintestinais ou da incidência de OH Brooker I e IV (p > 0,05). Os dados existentes indicam que o ibuprofeno é seguro e eficaz na redução da incidência total de OH e de OH Brooker II e III durante o acompanhamento. No entanto, as conclusões são limitadas devido ao pequeno número de estudos; logo, mais estudos clínicos de alta qualidade são necessários para o desenvolvimento de diretrizes em relação à dose e duração ideal da terapia.

Abstract The current study aimed to assess broccoli's phytochemical profile and determine its antioxidant activity. Fresh broccoli was procured from a local farm and divided into two major treatment groups (cooked and dried). There were five sub-treatments in the cooking group (conventional, microwave, boiling, blanching, and steaming) and three treatments in the drying group (sun drying, freeze drying, and hot air drying). Ascorbic acid content, total carotenoids, TPC, TFC, and antioxidant activity were evaluated for every sub-treatment. The results depicted that the antioxidant constituent of cooked broccoli was complementary to dried broccoli samples. The maximum amount of ascorbic acid content (10.80 mg/100 g), total carotenoids (3.976 mg/g), total phenolic contents (225.80 mg/g), and the total flavonoid contents (42.92 mg/g) were found in freeze-dried broccoli. Freeze-dried broccoli also showed the highest antioxidant activity for DPPH free radical scavenging assay (62.45%), hydrogen peroxide radical scavenging assay (53.67%), and ABTS radical scavenging assay (65.84%).

Abstract Nanoemulsions are nanoscale self-assembled entities which are manufactured for improving the delivery of active pharmaceutical ingredients. Nanoemulsion technology is one of the best ways to encapsulate the functional components as it enhances the stability and bioavailability of the compound. In the present study, nanoemulsions were prepared by ultrasonic homogenization of dispersed phase (10-22%) and surfactants (3-9%) with vitamin A (0.25-2.5%). Nanoemulsions were characterized through various optical techniques and stability was assessed using thermal shock and freeze-thaw cycle. The results revealed that nanoemulsions with high percentage of surfactants were more stable and retained smaller particle size as compared to nanoemulsions with low surfactants percentage and high dispersed phase, contributed to phase separation and colour change. These emulsions can be further tested for any toxic/allergic effect on the biological model and may be incorporated into food products.

Abstract The aim of this study was to develop a bread enriched with varying level of ginger powder. Ginger powder incorporated in white flour at 0, 2, 4, 6 and 8% level to get a bread enriched with antioxidants and good rheological and sensorial properties. Total phenolic content (TPC) was gradually decreased with increasing percentage of ginger powder and maximum inhibition of DPPH was recorded (47.23%) at 2% supplemented sample. Texture of supplemented bread samples was increased in terms of hardness, gumminess and chewiness as compared to control sample. Mineral contents increased in each sample with increasing percentage of ginger powder such as Na (451.69 mg/kg), Ca (127.32 mg/kg), K (427.61 mg/kg), Fe (15.19 mg/kg), Zn (7.04 mg/kg) and Cu (3.47 mg/kg) respectively. However, showed worst results regarding rheological properties with hard dough structure. Among studied samples, a range of 2-4% ginger powder presented high antioxidants with better rheological characteristics compared with control samples.

Abstract Moringa the miracle tree is rich source of protein and its protein content are comparable with meat protein. In the current study protein was isolated from moringa flowers and utilized in preparation of bars. Physicochemical analysis like texture, color, caloric value, water activity, pH and sensory characteristics were determined to evaluate the nutritional and quality attributes of bars. Different concentration of isolated protein was used in the preparedness. Among all treatments T4 (15% protein isolate) and T3 (10% protein isolate) were best as they had the highest caloric value i.e. 498.33 and 480.37 kcal and high protein percentage 42.55 and 35.29%. T4 and T3 also were good in all textural parameters i.e. hardness 4.68 and 4.85 kg, firmness 3.88 and 3.67 kg, toughness 3.78 and 3.63 kg and work of shear 16.84 and 16.80 kg/mm. The obtained results indicated that the incorporation of moringa protein isolate in bars not only increase their aesthetic value but also increase their nutritional profile. High quality protein isolated from moringa is cheaper and easily grown with little care to provide ample supply of moringa protein to peoples which were in concern of money for provision of proteinaceous food to their families to combat malnutrition.

Abstract The trend towards tunnel farming and hydroponic systems is increasing owing to the climatic changes as well as the need to increase crop yield. Hydroponic is a technique of growing plants without soil. Tunnel farming and hydroponic system requires controlled environmental parameters like temperature, humidity and soil moisture for better production of crops. This paper presents an effective method, named, ACHPA (Automatically Controlled Hydro-Ponic Agriculture) scheme that monitor and controls environmental parameters using sensors and controller. ACHPA provides better environmental control over traditional manual monitoring and controlling, thus yield high-quality crops. Sensor based monitoring and control system regulates the temperature and humidity of the tunnel to yield better. For the sake of saving water, an efficient method of drip irrigation is implemented which delivers water directly to the plants rather than being sprayed on as in conventional farming method. The proposed system here is tested for controlled environment and observations recorded for crop analysis purpose. This makes an effective solution to growing highly efficient, good quality and disease free crop production.

ABSTRACT Drinking water quality is considered to be of vital importance for all human beings and animals but its significance is much more heightened when consumer is a teenager. In view of foregone, groundwater quality assessment of 150 public schools situated in flooded areas of Southern Punjab, Pakistan, was carried out. Analysis results revealed that 49 and 37 % water samples are contaminated with coliform and faecal coliforms, respectively. On the other hand chemicals constituents in samples, including calcium (43 %), magnesium (11 %), potassium (37 %), sodium (31 %), sulphate (39 %), hardness (31 %), total dissolved solids (TDS) (35 %) and chloride (15 %) were higher than World Health Organization (WHO) limits. The situation is more serious as fluoride, iron and arsenic were also found in high concentration in 15, 60 and 58 % samples, respectively. Health risk assessment data indicated that mean chronic daily intake (CDI) values for children and adults were 0.592 and 0.537 μg/kg/day for arsenic and 0.012 and 0.011 μg/kg/day for iron, respectively. Calculated arsenic health risk index (HRI) > 1 for 88 and 58 % water samples for children and adults respectively, which highlights possible health risks associated with intake of contaminated water.

RESUMEN La calidad del agua potable se considera de vital importancia para todos los seres humanos y animales, pero su importancia aumenta mucho más cuando el consumidor es un adolescente. En vista de lo anterior, se llevó a cabo una evaluación de la calidad de las aguas subterráneas de 150 escuelas públicas ubicadas en áreas inundadas del sur de Punjab, Pakistán. Los resultados del análisis revelaron que 49 y 37% de las muestras de agua están contaminadas con coliformes y coliformes fecales, respectivamente. Por otro lado, los componentes químicos en las muestras que incluyen calcio (43 %), magnesio (11 %), potasio (37 %), sodio (31 %), sulfato (39 %), dureza (31 %), sólidos disueltos totales (TDS) (35 %) y cloruro (15 %)en 43, 11, 37, 31, 39, 31, 35 y 15% de las muestras fueron mayores que los límites de la Organización Mundial de la Salud (OMS). La situación es más ya que el fluoruro, el hierro y el arsénico también se encontraron en altas concentraciones en 15, 60 y 58% de las muestras, respectivamente. Los datos de evaluación de riesgo para la salud indicaron que los valores medios de ingesta crónica diaria (CDI, por sus siglas en inglés) para niños y adultos fueron de 0.592 y 0.537 μg/kg/día para arsénico y 0.012 y 0.011 μg/kg/día para el hierro, respectivamente. El índice de rieso, calculado para el arsénico, (HRI, por sus siglas en inglés) fue > 1 para 88 y 58% de muestras de agua para niños y adultos, respectivamente, lo que destaca los posibles riesgos para la salud asociados con la ingesta de agua contaminada.

Abstract Agricultural crops suffer many diseases, including fungal and bacterial infections, causing significant yield losses. The identification and characterisation of pathogenesis-related protein genes, such as chitinases, can lead to reduction in pathogen growth, thereby increasing tolerance against fungal pathogens. In the present study, the chitinase I gene was isolated from the genomic DNA of Barley (Hordeum vulgare L.) cultivar, Haider-93. The isolated DNA was used as template for the amplification of the ∼935 bp full-length chitinase I gene. Based on the sequence of the amplified gene fragment, class I barley chitinase shares 93% amino acid sequence homology with class II wheat chitinase. Interestingly, barley class I chitinase and class II chitinase do not share sequence homology. Furthermore, the amplified fragment was expressed in Escherichia coli Rosetta strain under the control of T7 promoter in pET 30a vector. Recombinant chitinase protein of 35 kDa exhibited highest expression at 0.5 mM concentration of IPTG. Expressed recombinant protein of 35 kDa was purified to homogeneity with affinity chromatography. Following purification, a Western blot assay for recombinant chitinase protein measuring 35 kDa was developed with His-tag specific antibodies. The purified recombinant chitinase protein was demonstrated to inhibit significantly the important phytopathogenic fungi Alternaria solani, Fusarium spp, Rhizoctonia solani and Verticillium dahliae compared to the control at concentrations of 80 µg and 200 µg.

Abstract Guava is very delicate and alluring fruit which is being ignored since very long time despite of highly nutritious fruit and rich source of Vitamin C. It contains Vitamin C 2-3 times more than orange. Naturally the guava fruit is enriched with vitamin C and polyphenoles. Guavas fruits after harvesting were dunked in solutions of CaCl2 (1, 2 and 3%) at room temperature for 5 minutes and stored for 24 days in 5% CO2 level at temperature of 10±1°C, while the humidity level of storage chamber were 80%. The stored fruits were analyzed at 6 days of interval for sugars (glucose, fructose and sucrose g/100g) total phenolic contents (mgGAE/100g), antioxidant activity (µmolTE/g), and organic acids (citric, tartaric, ascorbic, and malic acids mg/100 g). The total phenolic content and antioxidant activity of guava fruits were declined during progression in storage but in fewer amounts as compared to room storage condition. Citric acid and ascorbic acid contents were reduced with the progression in storage, however tartaric and malic acid values were amplified at end of storage but the rate of changes were slower. The pretreatments in combination with modified atmosphere storage escalate the shelf life of guava and slow down nutritional degradation process.

A síntese e o comportamento de fase de três novos polímeros cristais líquidos de cadeia lateral são descritos. Os novos polímeros apresentaram mesofase esmética C (SmC). O estudo de raios X para duas amostras revelou parcial interdigitação para a mesofase SmC do polímero com espaçador mais curto, enquanto que com espaçador mais longo o polímero não apresentou interdigitação.
