Magnesium an Important Nutrient in Pineapple Production in a Bayamón Sandy Clay
Authors: Hernández-Medina E.
Published: October 2020

This paper reports the results obtained in studies undertaken to determine the influence of magnesium and trace elements on the yield of pineapples grown in a Bayamón sandy clay, a soil typical of the pineapple-growing area of the Island. The trace elements tested were iron, boron, zinc, copper, and molybdenum. The experimental results gathered are briefly summarized as follows: 1. Neither the use of trace elements nor lime was effective in increasing yields of pineapples significantly. 2. In most cases magnesium was the only nutrient which significantly influenced pineapple yields. Magnesium-treated plants produced, on the average, 2.7 tons more fruit per acre than the check plants. 3. Highest fruit yields were associated with the highest leaf-magnesium contents. 4. A significant correlation was found between relative yields and leaf-magnesium values. 5. Based on the data presented herein it is suggested that magnesium be incorporated in the fertilizer mix or in foliar sprays so as to increase fruit yields per acre, when the magnesium leaf content of plants grown on Bayamón sandy clay falls below 0.20 percent.

Authors: Rico Ballester M. , Samuels G. , López García J.
Published: October 2020

Fertilizer trials were made with tomatoes, Rutgers variety, and cucumbers, P.R. 39 and Ashley varieties, in the Southwestern section of Puerto Rico with the following results: 1. For tomatoes at Jayuya, on a Jayuya silty clay loam, highest yields were obtained with 50 pounds of nitrogen and 100 pounds each of P2O5 and K2O per acre. Liming at 1,000 pounds per acre did not increase yields significantly. 2. The more fertile Santa Isabel clay of the Lajas Valley failed to respond significantly to variations in nitrogen, phosphate, or potash for tomatoes or cucumbers. 3. Cucumbers grown on a Paso Seco silty clay loam at the Fortuna Substation showed significant yield responses to 100 pounds of nitrogen and 50 pounds of P2O5 per acre.

Through the employment of X-ray diffraction patterns and petrographic-microscope studies the silica present in the internodes was identified as mineral opal, being clear, colorless, and isotropic, with an index of refraction of 1.45.
Sucrose-Enzyme Relationships in Immature Sugarcane as Affected by Varying Levels of Nitrate and Potassium Supplied in Sand Culture
Authors: Alexander Alex G.
Published: October 2020

Immature sugarcane plants grown in sand culture were subjected to conditions of potassium and nitrate stress in order that abnormal carbohydrate levels would be induced. The objective was to learn what areas of sugar metabolism were involved in the degradation of sucrose. The methods centered upon leaf enzymes, of which the following were identified and measured: Amylase, invertase, hexokinase, acid phosphatases, phosphorylase, phosphohexose isomerase, aldolase, triose phosphate dehydrogenase, phosphoglyceryl kinase, pyruvic carboxylase, condensing enzyme, α-ketoglutaric carboxylase, isocitric dehydrogenase, cytochrome-C reductase, fumarase, transaminase, oxalacetic carboxylase, peroxidase, catalase, and polyphenol oxidase. The enzyme preparations consisted of dialyzed water-soluble protein extracted from freeze-dried leaf tissue and precipitated with ammonium sulfate between 32- and 95-percent saturation. Sugar determinations for leaf and sheath tissue included total ketoses, sucrose, fructose, total reducing sugars, and glucose. Sheath-percent-moisture, total dry weight, and leaf protein were also measured. Treatments were applied from 9 weeks to 27 weeks of age and a total of seven harvests were made at 21-day intervals.

Changes in Leaf-Sugar Content and Enzyme Activity of Immature Sugarcane Following Foliar Application of Indole-3-Acetic Acid, 2,4-Dichlorophenoxyacetic Acid, and Maleic Hydrazide
Authors: Alexander Alex G.
Published: October 2020

Indole-3-acetic acid, 2,4-dichlorophenoxyacetic acid, and maleic hydrazide were applied as foliar sprays to 10-week-old sugarcane plants during initial studies of the interrelationships of growth-regulating materials with the sugar-metabolizing enzymes of sugarcane. Leaf samples were harvested at 1, 3, 9, and 27 days following treatment for sugar and enzyme assays. Sugar analyses were run for total ketoses, sucrose, fructose, and total reducing sugars, with glucose being determined by calculation. A series of acid phosphatase assays were conducted using as substrates the following compounds: ß-glycerophosphate, adenosinetriphosphate, uridine diphosphate glucose, glucose-1-phosphate, glucose-6-phosphate, fructose-6- phosphate, fructose-1,6-diphosphate, and 3-phosphoglyceric acid. Additional enzymes included invertase, amylase, hexokinase, phosphohexose isomerase, aldolase, triosephosphate dehydrogenase, phosphoglyceryl kinase, condensing enzyme, isocitric acid dehydrogenase, transaminase, peroxidase, and glucose oxidase. All enzyme preparations consisted of dialyzed water-soluble protein extracted from freeze-dried leaf tissue and precipitated with ammonium sulfate between 35 and 95 percent of saturation.

Authors: Arroyo-Aguilú José A. , Rivera-Brenes Luis
Published: October 2020

A study was undertaken to determine the relationship between percentages of crude protein and of apparently digestible protein in some forages of Puerto Rico. A regression equation was developed to predict the percentage digestible-protein content (F) from percentage crude-protein content (X) on a dry-matter basis: F = 0.819X — 2.05. A highly significant correlation of 0.90 was obtained. Using this same equation, the percentage predicted digestible-protein content (table 1) was calculated for all samples.

Hydrolytic Proteins of Sugarcane: The Q Enzyme
Authors: Alexander Alex G.
Published: October 2020

A polysaccharide branching factor, apparently identical with the Q enzyme of potatoes, has been extracted from sugarcane leaves and partly characterized. Procedures used successfully by other workers to isolate the Q enzyme from potato extracts failed to yield the branching system free from other catalysts of sugarcane. A preparation satisfactory for characterization studies was obtained by precipitating protein from water extracts with lead acetate, eluting the precipitate with bicarbonate solution, and fractionating the bicarbonate extract with ammonium sulfate. The Q enzyme was precipitated between 0 and 35-percent saturation, at pH 7.2 and 22°C. The 0 to 35-percent fraction was virtually free of acid phosphatase and ß-amylase. Traces of starch phosphorylase (P enzyme) were present but caused no difficulty in the absence of phosphate buffers. However, an amylase of the a type was present, which interferred seriously with Q enzyme measurements in acid media, particularly in the area of pH 4 to 5. Q enzyme was moderately active between pH 6.5 and 9.0, with optimum pH at approximately 7.5. The α-amylase was very weak at pH values higher than 6.5. Soluble potato starch was employed as substrate throughout these studies. Optimum concentration was 2.0 to 2.5 mg./ml. of digest,  α-amylase was most active against 0.5 mg./ml. of digest. Q enzyme experienced an 85-percent inhibition by lead ions, 0.5 mg./ml., when acting upon a substrate level of 0.25 mg./ml. of digest. Increasing the starch concentration to 2.5 mg./ml. partly removed the lead effects, indicating that the inhibition was competitive. Fluoride, 0.025 mg./ml., completely eliminated α-amylase activity at pH 7.5, but had little effect at pH 4.0. α-amylase was also suppressed by copper. Dialysis against distilled water had little effect upon Q enzyme, but strongly retarded amylase after 6 and 10 hours. Twenty-two-hour dialysis caused no further changes in either enzyme. The most favorable temperature tested with Q enzyme was 30°C, although the system was fairly active at temperatures as low as 7°C. α-amylase was not active at 7°C, but achieved the maximum rate measured at 26°C. A series of sugarcane tissues was tested for Q enzyme, including meristem, leaves +1 and +2, leaves +6 and +7, sheaths +1 and +2, 8 to 10 nodes, and 8 to 10 internodes. Activity was far greater in leaves +6 and +7 than any other tissue tested, α-amylase was most active in the meristem preparations. Electrophoresis studies showed that the 0 to 35-percent fraction was composed of at least three distinct protein constituents. These were presumed to represent Q enzyme, α-amylase, and starch phosphorylase. The significance of Q enzyme in sugarcane is briefly discussed. A diagram is presented to illustrate the role of the polysaccharide branching factor in relation to the starch -and sucrose-forming pathways.

The presence of Q-fever antibodies was determined in 278 of the 561 milk samples from an equal number of Puerto Rican dairy herds tested by the capillary-tube agglutination technique. The incidence of positive agglutinations was found to be 49.55 percent. Over 50 percent of the dairies of Hatillo and Arecibo, the two with the largest numbers of dairy herds in Puerto Rico, showed positive agglutinations.
Hydrolytic Proteins of Sugarcane: Amylase
Authors: Alexander Alex G.
Published: October 2020

Amylase was extracted from lyophilized tissues of the meristem, leaf, sheath, node, and internode areas of 10-month-old sugarcane. Immature leaves (—1 and 0) were the richest source, while strong activity was also obtained with 8- to 10-node preparations. About 70 percent of the amylase of water extracts was precipitated with ammonium sulfate between 48- and 60-percent saturation. Both potato starch and amylopectin were readily hydrolyzed, although amylose, corn starch, and inulin were also acted upon. Maximum velocity was obtained with 8 mg. of amylopectin per milliliter of digest. Optimum pH was 5.5. Amylase was highly active between pH 4.5 and 6.0, and declined rapidly above pH 6. Amylase was almost inactive at 16° C , but increased seventeenfold to a maximum at 50° C. Both mercury and iodide completely inhibited amylase at 1 X 10-4 µmoles/ml. of digest. The effects of iodide, and to a lesser extent of mercury, were reversed by increasing substrate concentrations. Magnesium partly inhibited the enzyme at 0.1 µmole/ml. Manganese stimulated amylase over the range of 0.003 to 0.60 µmole/ml. of digest. Thirty-six- to forty-eight-hour dialysis of amylase preparation against distilled water caused moderate activity decreases of 35 to 50 percent. The activity was readily restored with added manganese and traces of sugars. Sucrose was least effective, but maltose, galactose, glucose, and fructose all stimulated amylase activity above that of control, i.e. undialyzed, preparations. Several similarities were observed between amylase and invertase, including identical saturation ranges during salt fractionation, identical pH optima, similar responses to increasing temperature, inhibition by mercury, and activation by manganese and sugars. It is suggested that the amylases and α-glucosidase of sugarcane are very closely related, if not identical, and that a common property of the two types of enzymes is an affinity for α-glucosidic bonds.
Comparison of Simple vs. Complex Concentrate Mixtures for Dairy Cattle in Puerto Rico: Feeding Lactating Cows Receiving Fair-Quality Forage
Authors: Randel Paul F.
Published: October 2020

A double-reversal experiment with 80-day periods, extending from day 26 to day 265 of lactation, was conducted with 2 groups of 10 cows each. The two treatments consisted of two different concentrate mixtures, one of which had a simple formula consisting of ground shelled corn, soybean-oil meal, fortified molasses, bonemeal, and salt, and was prepared at the Substation, while the other was a complex mixture obtained from a commercial source. Both mixtures contained nearly the same level of crude protein. Concentrate allowances were based upon the Maryland Standards. The remainder of the ration consisted of a moderate amount of sorghum silage, or occasionally green chopped grass, and low-quality pasture. The simple-concentrate mixture proved to be more palatable than the complex mixture. The lactational response obtained with the simple mixture as compared with the complex mixture was significantly (P < 0.01) greater in production of milk uncorrected for fat content, 28.2 vs. 27.1 pounds per day, though not significantly different in production of 4-percent fat-corrected milk nor in production of milk fat. The efficiency of utilization of the simple mixture was significantly, P < 0.05, better for the production of milk uncorrected for fat content, 55.3 vs. 56.8 pounds of concentrates per 100 pounds of milk produced, but not significantly better for the production of 4-percent fat-corrected milk. The cost of concentrates per 100 pounds of milk produced was $2.34 for the simple and $2.67 for the complex mixture. It is concluded that, under conditions of the present experiment, in which forage was limited in quantity and of only fair quality, a simple concentrate mixture formulated to supply digestible energy at a minimum cost is just as adequate nutritionally for lactating cows as a concentrate mixture containing a multitude of different ingredients and supplemented with minerals, vitamins, and antioxidants. It is further concluded that the use of such simple concentrate mixtures prepared at the dairy farm will result in a reduction in feeding costs, provided the operation is large enough to offset the cost of the required machinery. A possible alternative would be the commercial preparation by feed mills of simple concentrate mixtures which could be sold to dairymen at a lower price than the present complex commercial mixtures.
Predatory and Parasitic Agents Attacking the Hippelates pusio Complex in Puerto Rico
Authors: Legner E. F. , Bay E. C.
Published: October 2020

Hymenopterous parasites found attacking the Hippelates pusio complex in Puerto Rico in 1963 were Ooencyrtus submelallicus Howard (5 percent), Spalangia drosophilae Ashmead (2 percent), Spalangia nov. sp. (10 percent), Pteromalidae Genus sp. (9.9 percent), all pupal parasites; and a new species of Cynipidae, Trybliographa sp., a larval parasite (6.4 and 10.3 percent). An unidentified clear mite infested up to 6.1 percent of field-collected adults. Predacious ants were Tapinoma melanocephalum (F.), Monomorium pharaonis (L.), Wasmannia auropunctata (Reg.), Solenopsis geminata (F.), and Tetramorium guineense (F.).  Parasite activity was apparently not seasonal but was localized in the southwest portion of the Island.
Effects of Tungsten and Molybdenum on Sucrose Content and Hydrolytic Enzymes of Immature Sugarcane
Authors: Alexander Alex G.
Published: October 2020

Variable concentrations of tungsten and molybdenum were applied as foliar sprays to 12-week-old sugarcane grown in sand culture. The objectives were to evaluate both elements as in vivo inhibitors of amylase, invertase, and acid phosphatases, and to test further the hypothesis that such inhibition will result in increased sucrose content. Leaf and meristem samples were harvested just prior to initial treatment, and at 3, 9, and 27 days thereafter. Glucose-1-phosphatase and amylase were generally inhibited by both elements, and increased sucrose usually appeared as a consequence. Tungsten at 10 p.p.m. significantly increased sucrose in leaf and meristem at all posttreatment harvests. Molybdenum was a more effective phosphatase inhibitor than tungsten, but was less effective in promoting sucrose production. Molybdenum increased sucrose in meristem only. ß-glycerophosphatase and ATP-ase were stimulated by some of the treatments. This was totally unexpected since both enzymes are known to be inhibited by tungsten and molybdenum in vitro. Certain treatments appeared to reduce the enzymes' capacity to experience major fluctuations. The significance of this property and the stimulation of ATP-ase are discussed at length.
Sucrose-Enzyme Relationships in Immature Sugarcane Treated With Variable Molybdenum, Calcium, Iron, Boron, Lead, Trichloroacetic Acid, Beta-glycerophosphate, and Starch
Authors: Alexander Alex G.
Published: October 2020

Variable levels of the elements molybdenum, calcium, iron, lead, and boron, as well as trichloroacetic acid, ß-glycerophosphate, and starch, were supplied to immature sugarcane grown in the greenhouse. Molybdenum, calcium, and iron were provided in factorial combination to plants in sand culture. Molybdenum, lead, and starch were applied as foliar sprays to a second group of plants grown in soil, and boron, ß-glycerophosphate, plus trichloroacetic acid were likewise applied to the foliage of plants grown in soil. The objectives of these experiments were to determine whether any of the applied materials could alter the action of specific enzymes, and, if so, whether significantly greater sucrose content would result. Leaf and meristem tissues were assayed for sugars, and for the enzymes amylase, invertase, acid phosphatases, starch phosphorylase, peroxidase, and polyphenol oxidase. Molybdenum significantly increased sucrose when applied as a foliar spray (80 p.p.m.), and as a nutrient in sand culture (1 p.p.m.). The molybdenum effect was retarded or reversed when either high calcium (9 p.p.m.) or high iron (6 p.p.m.) was supplied concurrently. Acid phosphatases and amylase were suppressed by high molybdenum, although these effects were greatly dependent upon calcium and iron supply. When applied as a foliar spray, molybdenum suppressed amylase and the phosphatase hydrolyzing glucose-1-phosphate, but not ATP-ase or ß-glycerophosphatase. Invertase was suppressed by high iron (6 p.p.m.) when molybdenum and calcium were low, but was stimulated when molybdenum was high. Lead, when applied to leaves at the rate of 50 p.p.m., caused moderate sucrose increases. Glucose-1-phosphate phosphatase was suppressed by lead in leaves and meristem, as was starch phosphorylase in the leaves. Foliar starch application failed to stimulate amylase, while ß-glycerophosphate failed to inhibit starch phosphorylase or to induce greater phosphatase activity. A number of enzyme responses were obtained which do not happen in vitro, and known in vitro effects did not always appear when specific materials were applied to living plants. Trichloroacetic acid, in particular, appeared to stimulate rather than inhibit enzyme action in vivo. This and other consequences of applying enzyme-regulating materials are discussed in detail.

De-Colourisation of Textile Dye Effluents using cost-effective Nigella Sativa Seed Waste
Authors: Raja Balasaraswathi S and Kiruba T
Published: October 2020

The textile industry is one of the major industries contributing to water pollution. The wet processing of
textiles involves the usage of a wide variety of chemicals and dyes. This water-intensive process can
potentially affect the water bodies by its effluents. The treatment of dye effluents and reusing of the water
could be the possible solution to reduce the impact. Adsorption is one of the most common methods used for
textile effluent treatment. Various bio-adsorbents are explored to make the adsorption more sustainable.
Nigella Sativa (Black cumin) seeds and its oil are having good medicinal value. The seed-waste left after the
oil extraction is found to have active components that can be used as an effective bio-adsorbent. The dye
removal efficiency of Nigella Sativa seed-waste is investigated under different experimental conditions
(varied adsorbent dose, temperature, pH, and contact time) for reactive dyes. The maximum removal
efficiency of 91% is obtained at the optimized experimental condition. Thus the study emphasizes that the
no-cost Nigella Sativa seed-waste can be used as an effective bio-adsorbent for reactive dye removal from
dye effluents.

Clinically-targetable vulnerabilities in cancer metabolism: A systematic review and meta-analysis
Authors: Arslaan Javaeed  , Sanniya Khan Ghauri
Published: October 2020

Abstract

Objectives: To investigate the efficacy and safety of targeting cancer metabolic vulnerabilities with specific anticancer agents.

Method: The systematic review and meta-analysis entailed search on PubMed, Embase and Google Scholar databases for cohort-based studies or clinical trials which reported hazard ratio for overall survival and/or median overall survival of patients treated with metabolically-active anticancer drugs. Data was analysed using the Number Cruncher Statistical System version 11.

Results: There were 16 studies published between 1989 and 2018 that reported improvement in the overall survival (p=0.05) despite the reported significant heterogeneity across the studies (I2=70%). Exploiting amino acid metabolic vulnerabilities was associated with a favourable prognostic outcome (p=0.05), while targeting glycolysis and nucleic acid synthesis had no significant clinical importance (p>0.05).

Conclusion: There is an urgent need to develop future therapies relying on the synergistic actions of nucleotide biosynthesis, glycolysis and amino acid metabolism.

Medical benefits of Camel’s Milk: a comprehensive review
Authors: Sultan Fahad AlNohair
Published: October 2020

Abstract

In the last decade, there has been an emergent interest, supported by various experimental and epidemiological studies, for health benefits of camel milk, in preventing various pathologic conditions, ranging cancer to diabetes. However, the precise mechanisms by which camel milk induce these health benefits remain to be investigated. Various reports have shown that consumption of camel milk by diabetes patients on a daily basis reduces blood sugar and glycosylated hemoglobin (HbA1C) levels and also reduces insulin requirements. Despite that these findings provide scientific evidences of anti-diabetic activities of camel milk, research is yet to be initiated with assurance for patients of diabetes and other metabolic disorders. This review summarizes the medicinal values of bioactive constituents of camel milk and reviews camel milk findings from the most significant preclinical studies in diabetes.

Fiducia-warranty in the Romanian law - a possible practical transposition from the French law?
Authors: Chirieac Roxana
Published: October 2020

The fiducia is an institution of long standing tradition in the civil law systems, being regulated in these ever since the roman law period. But, by the assuming the Napoleon French Civil Code, the fiducia was taken out of the regulations of our country, until the entry into force of the 2011 Civil Code. Then, our legislator decided to acquire the French regulations and reintroduce in the national regulations the fiducia institution. Unfortunately, the institution did not come to know success – although meant to compete with the Anglo-Saxon trust, at the present moment there are up to 200 fiducia registered in Romania. On the opposite side, almost 20% of Americans owns a type of trust. The circumstances in Romania are similar to those in France, where the current regulation of the fiducia was „conceived”, where scholars as well as practitioners have tried the implementation of different variations of the fiducia in order to make the institution applicable. Thus were created fiducia-warranty (fiducie sûreté), fiducia management (fiducie gestion), and scholars have spoke about fiducia concessionary (fiducie libéralité). The present study aims to analyse the fiducia warranty institution and to suggest a „transposition” of this practice in the Romanian legislation. We do not consider that the fiducia will generate as much enthusiasm as the trust, that is much more flexible in its constitution as well as its exploitation, but we consider that it may develop its application in our national legislation.
Protonpompremmers voorschrijven aan zuigelingen en jonge kinderen: niet zo onschuldig

Protonpompremmers (PPI’s) worden wereldwijd steeds vaker voorgeschreven. Dat is niet anders in België. De richtlijnen voor de diagnose en de behandeling van gastro-oesofageale refluxziekte (GORZ) bij zuigelingen zijn niet veranderd en toch stellen artsen steeds vaker de diagnose van GORZ. Hierdoor ontstond er een overmatig gebruik van PPI’s, die men vaak voorschrijft aan baby’s die veel huilen. Al na één week PPI-gebruik ziet men een dysbiose van het darmmicrobioom, met een bacteriële overgroei in de dunne darm tot gevolg. Door deze dysbiose ontwikkelen of behouden zuigelingen die PPI’s toegediend krijgen vaak dezelfde klachten als degene waarvoor de ouders in de eerste plaats naar de raadpleging kwamen. Ook de overige gevolgen van PPI’s zijn echter niet te minimaliseren: infectieuze gastro-enteritis, associatie met een Clostridium difficile-infectie, een bacteriële pneumonie, astma, een hoger risico op fracturen en obesitas. Het is nog onduidelijk of probiotica het onevenwicht van het intestinale microbioom kunnen voorkomen of herstellen.
Opvang van de post-COVID-patiënt door de huisarts: een nieuwe uitdaging!
Authors: Van Nuland M , Remmen R
Published: October 2020

Het doormaken van het “coronavirus disease 2019” (COVID-19) kan naast de fysieke impact ook een grote weerslag hebben op het mentale welzijn. Zowel de verontrustende berichtgevingen, de quarantainemaatregelen, de maatschappelijke impact van de huidige pandemie, als mogelijke traumatische ervaringen (door acute ademhalingsproblemen, met soms snelle en onvoorspelbare evolutie naar een kritische toestand) en het lange herstelproces met grote beperkingen in het functioneren, kunnen daartoe bijdragen. Psychische stoornissen en symptomen, zoals angst, depressie, posttraumatische stress, slapeloosheid, rouw en neurocognitieve symptomen zijn te verwachten tijdens en na het doormaken van COVID-19. Hulpverleners anticiperen bij een subgroep van patiënten ook een evolutie naar chronische somatische symptomen, zoals postinfectieuze vermoeidheid. Gebaseerd op de ervaringen vanuit een geïntegreerde intramurale aanpak bij gehospitaliseerde COVID-19 patiënten, wordt het belang van aandacht en begeleiding voor mentaal welzijn in de nazorg onderstreept en worden aanbevelingen voor de eerste lijn geformuleerd. Daarbij wordt de nadruk vooral gelegd op vroege detectie en brede, laagdrempelige ondersteuning. Centraal staan de ondersteuning bij herstel na hospitalisatie (d.m.v. psycho-educatie en begeleiding) en het leren toepassen van de juiste copingvaardigheden bij langdurige klachten.
