    Notes: Patties from a Control (all meat), Treatment I (meat, 1.1% water, 1.0% NaCl and 0.5% STP) and Treatment II (meat, 11.1% water, 1.0% NaCl and 0.5% STP) were frozen for 0 to 24 wk, broiled, and analyzed for color attributes. Treated patties had lighter exterior surfaces with reduced redness and increased yellowness. The opposite effects were observed for the interior of patties. Treatment II had elevated values for internal yellowness as compared to Treatment I. Storage caused an increase in both external and internal color values. Sensory scores indicated that internal redness of treated patties was greater than that of the Control but gradually decreased during storage.

    Description / Table of Contents: Resumé Objectif Le lévonorgestrel (LNG), à faible dose de progestine, n'a pas d'effet sur la lactation mais, comme tous les médicaments que prennent les femmes qui allètent, il peut être transmis au nourrisson dans le lait de la mère. Savoir comment les enfants de différents âges assimilent ce produit indésirable qu'ils ingèrent par le lait maternel permettrait de décider à quel moment on peut recommander cette méthode de contraception aux femmes durant la lactation. Méthode Cette étude a porté sur 30 femmes qui nourrissaient exclusivement au lait maternel leurs enfants de 4, 12 et 24 semaines. On a administré aux mères, pendant 5 semaines, des doses journalières de 30 μg de LNG, exposant ainsi l'enfant au médicament durant cette période. Résultats Les enfants de 4 semaines ne pouvaient ni absorber ni métaboliser efficacement le LNG. Ceux de 12 semaines pouvaient le métaboliser plus efficacement que l'absorber. Ceux de 24 semaines pouvaient et le métaboliser et l'absorber efficacement. Conclusion Le LNG peut être recommandé sans risque, 12 semaines après l'accouchement, aux mères qui allaitent leurs nourrissons.
    Abstract: Resumen Objetivo El levonorgestrel (LNG), progestina de dosis baja, no afecta la lactación pero, como todas las drogas administradas a madres lactantes, puede ser transferida al bebé a través de la leche materna. El modo en que los bebés de diversas edades manejan esta droga materna no deseada ayudaría a decidir cuándo recomendar este método anticonceptivo a madres lactantes. Métodos Este estudio se realizó con 30 madres exclusivamente lactantes y sus bebés de 4, 12 y 24 semanas de vida. Las madres recibieron diariamente 30 μg de LNG durante un período de cinco semanas, exponiendo así a sus hijos a LNG materno durante dicho período. Resultados Los bebés de 4 semanas no podían absorber ni metabolizar el LNG eficientemente. Los bebés de 12 semanas podían metabolizar el LNG más eficientemente que absorberlo. Los bebés de 24 semanas podían metabolizarlo y absorberlo eficientemente. Conclusión La administración de LNG a madres lactantes a las 12 semanas del posparto no representa problemas.
    Notes: Abstract Objective Levonorgestrel (LNG), a low-dose progestin, does not affect lactation but like all drugs taken by breastfeeding mothers, it can be transferred to the infant via breast milk. How infants of various ages cope with this unwanted maternal drug would help in deciding when to recommend this method of contraception to breastfeeding mothers. Methods The study was conducted in 30 exclusively breastfeeding mothers and their 4-, 12- and 24-week-old infants. The mothers daily received 30 μg LNG over a five-week period, thus exposing their infants to maternal LNG for that period. Results Four-week-old infants could neither absorb nor metabolize LNG efficiently. Twelve-week-old infants could metabolize LNG more efficiently than absorb. Twenty-four-week-old infants could do both efficiently. Conclusion It is safe to introduce LNG to breastfeeding mothers at 12 weeks postpartum.

    Notes: Abstract High spin states in theN=50 nucleus93Tc were reinvestigated by using the reaction64Zn (35Cl,4p 2n) at a beam energy of 140 MeV. This was done particularly with a view to observe anyγ rays upto 2.7 MeV which may have been missed in our earlier study where the experimental conditions were set to observeγ rays upto 2 MeV. We found four newγ rays of energy: 2484, 2164, 2130 and 69 keV. We have placed theseγ rays in the level scheme and it now gets extended to 49/2−. Though there is no substantial change in the level scheme, placing theγ rays in the level scheme has resulted into two important conclusions: (1) We have performed shell model calculations for93Tc nucleus within a model space which encompasses an enlarged proton configuration and allows for the excitation of the neutron across theN=50 core. The excitation of a single neutron across theN=50 core satisfactorily explains the new level scheme. (2) The energy of the 17/2− isomeric state is now unambiguously placed at 2185 keV.

    Description / Table of Contents: Resumé Bien que méthode contraceptive importante et efficace, l'allaitement est sérieusement restrictif en ce sens que la protection contraceptive qu'il offre à la mère cesse soudainement sans donner aucun signe physique du retour à la fécondité. Il semble que, de nos jours, les méthodes de barrières et les types de contraceptifs hormonaux à la seule progestérone, qu'ils soient sous forme de pilules, d'implants ou d'injections, soient les solutions les plus adaptées dans le cas d'allaitement maternel, puisque ni les unes ni les autres de ces méthodes n'ont d'effets indésirables sur la lactation et que l'infime quantité de progestérone (NET ou LNG) transmise à l'enfant ne compromet nullement la croissance et le bien-être du nouveau-né. L'insertion d'un DIU en période puerpérale comporte en soi un risque de maladie pelvienne inflammatoire, des taux d'expulsion élevés, et des ménorragies lorsque reprennent les menstruations. Les contraceptifs combinés modifient tant la qualité que la quantité de lait chez la mère et sont donc déconseillés. La stérilisation est une méthode terminale et, de ce fait, n'est utile que si la famille est au complet.
    Abstract: Resumen Si bien el amanantamiento es un método anticonceptivo importante y eficiente, tiene una gran limitación, es decir, que la protección anticonceptiva que ofrece a la madre lactante cesa abruptamente sin dar ninguna indicación fisica del retorno de la fecundidad. Los métodos de barrera y los tipos de anticonceptivos hormonales con progesterona solamente, ya sea en forma oral, de implante o inyectable, parecen ser la alternativa anticonceptiva primaria para la madre lactante hoy en dia. Ninguno de los dos afecta adversamente la lactancia y la cantidad muy pequeña de progesterona (NET o LNG) transferida al bebé no afecta su crecimiento ni bienestar fisico. La colocación puerperal del D.I.U. presenta un riesgo inherente de enfermedad pélvica inflamatoria, altas tasas de expulsión y menorragia al reanudarse la menstruación. Los anticonceptivos combinados afectan tanto la calidad como la cantidad de leche materna y, por consiguiente, no son recomendados. La esterilización es un método terminal y por este motivo es útil sólo cuando la familia ha quedado completa.
    Notes: Abstract Breast feeding, though an important and efficient contraceptive method, suffers from one major limitation: the contraceptive protection it offers the nursing mother ends abruptly without giving any physical indication of the return of fertility. Barrier methods and progesterone-only hormonal contraceptives, either in the oral, implant or injectable form, appear to be the primary contraceptive alternative for the nursing mother today. They neither adversely affect lactation, nor does the minute quantity of progesterone (NET or LNG) transferred to the infant affect its growth and physical well-being. Puerperal insertion of IUD carries an inherent risk of pelvic inflammatory disease, high expulsion rates and menorrhagia, once menses resume. Combination contraceptives affect both the quality and quantity of breastmilk; hence they are not recommended. Sterilization is a permanent method and therefore useful only when the family has been completed.

    Notes: Chemisorption and crosslinking of cotton cellulose has been carried out with DMEU, DMPU, DHEU, and DMDHEU. Various physicochemical properties of resin-treated samples have been studied and the data subjected to a linear regression analysis. Using the techniques of liquid retention and optical microscopy it has been found that the chemisorbed cotton is characterized by a lower level of bound resin, greater amount of methylol HCHO, and higher swellability of structure in comparison to the crosslinked cotton. This difference of behavior between the two cottons is attributed to greater rigidification and a collapse of porous structure in crosslinked cotton as a result of catalytic activity at the curing temperature. For various resin-treated samples there exists a linear relationship between the strength and recovery characteristics of single fibers and those of fiber bundles. The losses in fiber strength and extensibility are found to be proportional to the level of bound resin in various samples. Crosslinked fibers show appreciably higher magnitudes of elastic recovery and bundle crease recovery than chemisorbed fibers. The significance of these results is discussed.
