Authors: Sethy Sujata , Mogra Renu
Published: May 2024

Multigrain cookie premixes were developed using finger millet (Eleusine coracana) to provide a nutritious food option for vulnerable groups, especially preschool children facing micronutrient malnutrition. Three types of cookie premixes were formulated with varying proportions of grains and evaluated for sensory parameters using a 9-point hedonic scale. The best combination of calcium and iron-rich ingredient s was found to be finger millet flour, refined wheat flour, grain amaranth, garden cress seed, milk powder in the ratio of 40:25:20:5:10. This premix was also evaluated for nutritional composition and shelf life. The cookies made from this premix were rich in essential nutrients, with 319.8 mg of calcium and 8.89 mg of iron per 100 g. The sensory evaluation showed that all the premixes were well accepted (sensory score >7) and the selected premix remained acceptable over a storage period of 90 days.

Authors: Núñez José Ezequiel Villarreal , Zachrisson Iván Alexis Ramos , Jaén Marcos Rodrigo Riquelme
Published: May 2024

The objective of the work was to characterize the properties of the soils of coffee-producing farms in the provinces of Cocle and Veraguas that allow the preparation of regionalized fertilization cards according to the edaphoclimatic characteristics of each area. Planting robusta coffee is gaining greater interest among Panamanian farmers as an alternative for soil conservation. On 16 farms in the province of Coclé and 18 in Veraguas, samples were taken (0-20 cm) to understand their properties and initiate a sustainable fertilization program that contributes to improving productivity.
Digital maps were created using the Q-Gis v.3.32.1 program and regionalized fertilization cards for each zone. The soils of the province of Coclé presented a high percentage of aluminum saturation, 88% with low porosity problems, average pH of 4.9, low levels of organic matter and phosphorus (100%), and 75% low in potassium. 56% low in calcium. Imbalances were found in the Ca/Mg and Ca + Mg/K ratios, which causes nutritional problems. In Veraguas soils, 22% presented a high percentage of aluminum saturation, 67% average acid pH, 94% low organic matter and phosphorus content, 89% low in potassium, medium and high levels of magnesium and calcium. A positive and statistically significant correlation was found between % clay, organic matter, pH, and calcium. It is expected that this soil characterization and regionalized fertilization cards will contribute to improving soil properties and achieving sustainable production. Fertilization recommendation cards have been prepared for these two provinces and they take into account this entire situation and physical problems found in the soils. Much emphasis is also placed on organic fertilization of plantations as a complement to traditional fertilization, seeking more balanced nutrition.

Published: May 2024

Assessing the composition and structure of ecosystems is of the utmost importance for the conservation of forests. Tree species diversity, distribution pattern and stand structure provide baseline information for conservation and management of the forest. The present study was conducted in the Dalma Wildlife Sanctuary to assess the diversity, composition, richness and stand structure. Standard sampling method was used for vegetation sampling and data collection. An aggregate of 2876 individuals belonging to 41 species, 34 genera and 22 families were identified from 2.5 ha sampling area. The sanctuary recorded tree density of 1151 ind./ha with a total basal area of 510.807 sq. m. Analysis of IVI value revealed that S. robusta (65.207), B. cochinchinensis (22.451), A. latifolia (18.071), T. tomentosa (15.604) and D. melanoxylon (12.449) were the dominant tree species in the sanctuary. The family Fabaceae was the most species-rich family with 9 species. Over 70% of tree species showed contiguous distribution pattern in the studied area. The sanctuary recorded diversity index (H') of 3.204, richness index (R') of 4.504 and evenness index (E) of 0.863. The stand structure indicates a natural satisfactory regeneration and healthy population in the studied forest areas. Density-girth class distribution showed that more than 75% of the total population was dominated by seedlings and saplings. The research findings suggests that the sanctuary is an ecolologically rich site with an expanding population. An efffective management and conservation strategy will ensure a sustained biodiversity and richness of this protected site.

Authors: Priya Priyanka , Singh Shikha , Mohan Murari
Published: May 2024

Greengram ( Vigna radiata L. ), commonly called as mungbean is an important pulse crop grown mainly in Zaid and Kharif season in India. Organic farming is one of the sustainable farming practices that can overcome the harmful effects of chemical farming and provides quality production. A field experiment was conducted during Zaid, 2023 to study the “Effects of organic nutrients on growth and yield of summer Greengram (Vigna radiata L.)”  at SHUATS Model Organic Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The experiment was laid out in a randomized block design  with nine treatments replicated thrice. The treatment consisted of 3 different solid manures i.e. Farm Yard Manure, Vermicompost, Goat manure and 3 different liquid manures i.e. Fish Amino Acid, Panchagavya and Seaweed (Kappaphycus alvarezii) sap. The experimental field soil was sandy loam in texture, moderately basic in reaction (pH 7.8), available medium Organic Carbon (0.662 %)  low in available nitrogen (249.5 kg/ha), and very high accessible phosphorus (38.7 kg/ha) and available potassium (240.8 kg/ha). The result showed that significantly higher growth parameters viz., plant height (42.09 cm), number of nodules (22.22/plant), dry weight (19.35g/plant) and yield attributes such as effective pod/plant (11.05), seed/pod (9.68), test weight (38.41 g), seed yield (1643.54 kg/ha) and stover yield (3023.55 kg/ha) were observed with application 5 t/ha FYM and foliar spray of 7.5 % K sap (T9). Highest net return (Rs. 100383.30/ha) and benefit cost ratio (1.84) was also recorded in the same treatment. This concludes that application of 5 t/ha FYM along with foliar spray of 7.5 % K sap at 15 and 30 DAS performed better in terms of yield and economic returns.

Plastic pollution, particularly from polythene (polyethylene), has emerged as a significant environmental concern worldwide. In response to this challenge, microbial perspectives on polythene biodegradation have garnered attention as potential solutions to mitigate plastic pollution. This article provides an overview of the mechanisms underlying microbial polythene biodegradation, including surface erosion, biofilm formation, metabolic pathways, synergistic interactions, and adaptation. Furthermore, it explores the diversity of polythene-degrading microorganisms and their roles in plastic degradation across different environments. Environmental factors influencing polythene biodegradation, such as temperature, pH, moisture, and nutrient availability, are discussed, along with strategies to optimize degradation rates. Biotechnological approaches, including microbial consortia development and genetic engineering, are highlighted as promising avenues to enhance polythene degradation efficiency. The article concludes with a discussion on the potential of microbial perspectives to address plastic pollution and outlines future research directions in this field.

Background

Long-term results of laparoscopically assisted versus open ileocolic resection for Crohn's disease were evaluated in a randomized trial.

Methods

Sixty patients who underwent ileocolic resection between 1999 and 2003 were followed prospectively. Primary outcomes were reoperation, readmission and repeat resection rates for recurrent Crohn's disease. Secondary outcomes were quality of life (QOL), body image and cosmesis.

Results

Five patients were lost to follow-up. Median follow-up was 6·7 (interquartile range 5·7–7·9) years. Sixteen of 29 and 16 of 26 patients remained relapse free after ileocolic resection in the laparoscopic and open groups respectively (risk difference 6 (95 per cent confidence interval − 20 to 32) per cent). Resection of recurrent Crohn's disease was necessary in two of 29 versus three of 26 patients (risk difference 5 (−11 to 20) per cent). Overall reoperation rates for recurrent Crohn's disease, incisional hernia and adhesion-related problems were two of 29 versus six of 26 (risk difference 16 (−3 to 35) per cent). QOL was similar, whereas body image and cosmesis scores were significantly higher after laparoscopy (P = 0·029 and P < 0·001 respectively).

Conclusion

Laparoscopically assisted ileocolic resection results in better body image and cosmesis, whereas open surgery is more likely to produce incisional hernia and obstruction.
Optical, Redox, and DNA‐Binding Properties of Phenanthridinium Chromophores: Elucidating the Role of the Phenyl Substituent for Fluorescence Enhancement of Ethidium in the Presence of DNA
Authors: Prunkl Christa , Pichlmaier Markus , Winter Rainer , Kharlanov Vladimir , Rettig Wolfgang , Wagenknecht Hans‐Achim
Published: February 2010

The phenanthridinium chromophores 5‐ethyl‐6‐phenylphenanthridinium (1), 5‐ethyl‐6‐methylphenanthridinium (2), 3,8‐diamino‐5‐ethyl‐6‐methylphenanthridinium (3), and 3,8‐diamino‐5‐ethyl‐6‐(4‐N,N‐diethylaminophenyl)phenanthridinium (4) were characterized by their optical and redox properties. All dyes were applied in titration experiments with a random‐sequence 17mer DNA duplex and their binding affinities were determined. The results were compared to well‐known ethidium bromide (E). In general, this set of data allows the influence of substituents in positions 3, 6, and 8 on the optical properties ofEto be elucidated. Especially, compound4was used to compare the weak electron‐donating character of the phenyl substituent at position 6 ofEwith the more electron‐donating 4‐N,N‐diethylaminophenyl group. Analysis of all of the measurements revealed two pairs of chromophores. The first pair, consisting of1and2, lacks the amino groups in positions 3 and 8, and, as a result, these dyes exhibit clearly altered optical and electrochemical properties compared withE. In the presence of DNA, a significant fluorescence quenching was observed. Their binding affinity to DNA is reduced by nearly one order of magnitude. The electronic effect of the phenyl group in position 6 on this type of dye is rather small. The properties of the second set,3and4, are similar toEdue to the presence of the two strongly electron‐donating amino groups in positions 3 and 8. However, in contrast to1and2, the electron‐donating character of the substituent in position 6 of3and4is critical. The binding, as well as the fluorescence enhancement, is clearly related to the electron‐donating effect of this substituent. Accordingly, compound4shows the strongest binding affinity and the strongest fluorescence enhancement. Quantum chemical calculations reveal a general mechanism related to the twisted intramolecular charge transfer (TICT) model. Accordingly, an increase of the twist angle between the phenyl ring in position 6 and the phenanthridinium core opens a nonradiative channel in the excited state that depends on the electron‐donating character of the phenyl group. Access to this channel is hindered upon binding to DNA.

Sedimentary Enzyme Kinetics of Land/Water Ecotones with Reed Domination
Authors: Wang Liang , Yin Chengqing , Wang Weidong
Published: February 2010

Land/water ecotones, the transitional boundary zone between terrestrial and aquatic ecosystems, can effectively trap and assimilate nutrients from external sources. The changes of nutrient cycling will cause a response in enzyme activity. In this paper, the enzyme kinetics of land/water ecotones in a shallow eutrophic wetland in China, dominated by a reed (Phragmites australis) community, are studied. The results indicate that land/water ecotones exhibit a strong filtration function and nutrient factor is an important feature affecting the distribution of enzymes in the transect of the littoral zone. The obvious spatial differences of enzyme activities and nutrients are present in the transect of the reed beds. The land area is the hot zone, where significant changes in enzyme activity occur. T‐test results show that the landward spot, 1 m away from the water‐land interface, is quite different from other spots, and the 1 m spot is the hot spot where great biochemical change happens. The principal component analysis of the environmental variables shows that nutrient factors have an important affect on enzyme distribution in the transect of the littoral zone. The nutrient factor explains about 54% of the observed variance. In particular, TOC (total organic carbon) correlates with the other five factors (TN; total nitrogen, TP; total phosphorus, phosphatase, β‐glucosidase, and urease) with correlative coefficients of 0.932, 0.595, 0.488, 0.433, and –0.468, respectively. The results indicate that TOC is a very important factor in Baiyangdian wetlands.
Electrokinetic Removal of Petroleum Hydrocarbon from Residual Clayey Soil Following a Washing Process
Authors: Jeon Chil‐Sung , Yang Jung‐Seok , Kim Kyung‐Jo , Baek Kitae
Published: February 2010

This study investigates total petroleum hydrocarbon (TPH) removal from residual clayey soil, after a washing procedure, using an electrokinetic process. Eight electrokinetic experiments were carried out to investigate the characteristics of TPH removal. When 0.1 M MgSO4 or 0.1 M NaOH was used as an electrolyte, the electric current rapidly increased within the first 100 or 200 h, respectively. A negatively charged soil surface resulted in a more negative zeta potential and greater electroosmotic flow toward the cathode. Therefore, the accumulated electroosmotic flow (EOF) when using 0.1 M NaOH as the anolyte‐purging solution was higher than when using 0.1 M MgSO4. Although the energy consumption for the two purging solutions was similar, the efficiencies of TPH removal when 0.1 M MgSO4 and 0.1 M NaOH with surfactant were used were 0 and 39%, respectively, because the electroosmotic flow rate increased with TPH removal efficiency. When 5% isopropyl alcohol (IPA) was used as a circulation solution, the electric current increased but the TPH removal was similar to that using water. In terms of energy consumption, the use of a surfactant‐enhanced electrokinetic process with NaOH as electrolyte was effective in removing TPHs from low‐permeability soil.

La3FMo4O16 crystallizes in the triclinic crystal system with space group P$\bar {1}$ [a = 724.86(2) pm, b = 742.26(2) pm, c = 1469.59(3) pm, α = 101.683(2)°, β = 102.118(2)°, γ = 100.279(2)°] with two formula units per unit cell. The three crystallographically independent La3+ cations show a coordination number of nine each, with one F– and eight O2– anions forming distorted monocapped square antiprisms. The fluoride anion is coordinated by all three lanthanum cations to form a nearly planar triangle. Besides three crystallographically independent tetrahedral [MoO4]2– units, a fourth one with a higher coordination number (CN = 4 +1) can be found in the crystal structure, forming a dimeric entity with a formula of [Mo2O8]4– consisting of two edge‐connected square pyramids. Several spectroscopic measurements were performed on the title compound, such as infrared, Raman, and diffuse reflectance spectroscopy. Furthermore, La3FMo4O16 was investigated for its capacity to work as host material for doping with luminescent active cations, such as Ce3+ or Pr3+. Therefore, luminescence spectroscopic as well as EPR measurements were performed with doped samples of the title compound. Both the pure and the doped compounds can be synthesized by fusing La2O3, LaF3 and MoO3 (ratio 4:1:12; ca. 1 % CeF3 and PrF3 as dopant, respectively) in evacuated silica ampoules at 850 °C for 7 d.

The interaction between Cp*OsH(dppe) (1) and a series of proton donors (HA) of increasing strength [indole, CFH2CH2OH (MFE), CF3CH2OH (TFE), (CF3)2CHOH (HFIP), p‐nitrophenol, and HBF4·Et2O] has been investigated experimentally by variable temperature IR and NMR spectroscopy in solvents with different coordinating abilities (alkanes, dichloromethane and their mixtures) and computationally at the DFT/B3PW91 level using different models. Both the IR and NMR spectroscopic data for the interaction with weak proton donors conform to the criteria of M–H···H‐A bond formation. Theoretical calculations, however, indicate an asymmetric bifurcated interaction with a significant contribution from the metal atom, which is greater than that previously found for the corresponding Fe system. The basicity factor of 1 (Ej = 1.47) is greater than those of the Ru (1.39) and Fe (1.35) congeners, in agreement with previous studies on other compound families. The kinetic product of proton transfer, cis‐[Cp*Os(H)2(dppe)]+X–, which is selectively obtained at low temperatures, irreversibly rearranges to trans‐[Cp*Os(H)2(dppe)]+X– upon warming to >230 K. The latter compound with X = BF4 has been crystallographically characterized. The activation enthalpy of the isomerization process (ΔH≠ = 21.5 ± 1.0 kcal mol–1), obtained from kinetics investigation by 1H NMR in the 240–260 K range, is identical within experimental error to those previously reported for the M(η2‐H2)+BF4– → trans‐M(H)2+BF4– isomerization process of the iron and ruthenium analogues. The activation entropy (ΔS≠ = 12 ± 4 e.u.), on the other hand, is greater than for the lighter metals, following the order Fe < Ru < Os. The mechanism of proton transfer and trends in the energetics of the various steps upon changing the nature of the metal atom are discussed.
Betaine supplementation affects the cholesterol but not the lipid profile of pigs

Published: February 2010

This study was undertaken to investigate the effects of long term betaine intake on the cholesterol and lipid profile of Alentejano (AL) pigs. At ˜36 kg body weight (BW), castrated male and female pigs fed a commercial (C) diet, were divided into two groups: i) Group C, consuming the C diet; and ii) Group CB, consuming the C diet supplemented with 1 g/kg betaine. Pigs were slaughtered at ˜100 kg BW. Fasting plasma concentrations of protein, urea, glucose, TAG, phospholipids, homocysteine, total and LDL‐ and HDL‐cholesterol were determined. Liver TAG, phospholipids, and total and free cholesterol were analyzed, as well as total lipids, cholesterol contents, and fatty acid (FA) composition of M. semimembranosus and dorsal subcutaneous fat. Betaine supplemented pigs presented significantly higher plasma concentrations of TAG, phospholipids, cholesterol, and lipoprotein cholesterol. Dorsal subcutaneous fat cholesterol concentration was also significantly higher in CB than in C pigs. No differences were detected in the most abundant FA profile (including the unsaturated to saturated FA ratio) of muscle and subcutaneous fat tissues among treatments. These data suggest that betaine induces dyslipidemia, and increases cholesterol concentration in dorsal subcutaneous fat, without affecting the FA profile of M. semimembranosus and dorsal subcutaneous fat.
Loss of expression of ZAC/PLAGL1 in diffuse large B‐cell lymphoma is independent of promoter hypermethylation

Published: February 2010

ZAC/PLAGL1 is a ubiquitously expressed, imprinted tumor suppressor gene located on 6q24, a chromosomal region that is frequently deleted in diffuse large B‐cell lymphoma (DLBCL). Like p53, ZAC regulates cell cycle arrest and apoptosis concomitantly, and loss of expression is implicated in tumorigenesis in a variety of different cancers. In most tissues, ZAC transcription is monoallelic and driven by the paternal allele of promoter P1, which lies within a differentially methylated CpG island (DMR). In human blood cells, ZAC transcription is driven by promoter P2, which lies within an unmethylated CpG island and produces biallelic transcripts. Previous reports of epigenetic changes of ZAC in tumors have focused on P1, showing frequent loss of expression caused by paternal allele hypermethylation or loss of heterozygosity (LOH). As ZAC expression in normal B lymphocytes is derived from P2, in DLBCL we analyzed both promoters for gene expression, LOH and abnormal methylation. Loss of P2 transcription was observed in 8 of 11 lymphomas (73%), even though the P2 CpG island remained unmethylated. Three lymphomas showed evidence of LOH (23%), and abnormal methylation of the P1 DMR was observed in an additional four (31%), despite minimal P1 activity in normal B lymphocytes. These data indicate that downregulation of ZAC occurs in DLBCL, as in other cancers. However, unlike P1, transcriptional repression of P2 is not caused by hypermethylation of its associated CpG island in tumors. The mechanistic relationship between altered ZAC expression and epigenetic changes at its promoters thus appears more complex than previously supposed. © 2010 Wiley‐Liss, Inc.
