Comparing the Effects of Interactive and Noninteractive Complementary Nutrients on Growth in a Chemostat  [PDF]
James P. Braselton, Martha L. Abell, Lorraine M. Braselton
Open Journal of Applied Sciences (OJAppS) , 2013, DOI: 10.4236/ojapps.2013.35042
Abstract: We compare the effects of interactive and noninteractive complementary nutrients on the growth of an organism in the chemostat. We also compare these two situations to the case when the nutrients are substitutable. In previous studies, complementary nutrients have been assumed to be noninteractive. However, more recent research indicates that some complementary nutrient relationships are interactive. We show that interactive complementary and substitutable nutrients can lead to higher population densities than do noninteractive complementary nutrients. We numerically illustrate that if the washout rate is high, an organism can persist at higher densities when the complementary nutrients are interactive than when they are noninteractive, which can result in the extinction of the organism. Finally, we present an example by making a small adjustment to the model that leads to a single nutrient model with an intermediate metabolite of the original substrate as the nutrient for the organism.
Feeding Protected Lysine and Methionine Modifies Milk Protein Profile in Grazing Dairy Cows  [PDF]
Mónica Duque Quintero, Martha Olivera-Angel
Agricultural Sciences (AS) , 2019, DOI: 10.4236/as.2019.102018
Abstract: The experiment was designed to determine the effect of protected lysine (Lys) and methionine (Met) supply on milk protein profile in grazing dairy cows specifically in the caseins (CNs) and α-lactalbumin fractions. Twelve multiparous mid lactation Holstein cows producing 24 (±4.76) kg of milk were assigned to one of two treatments (six cows per treatment) during an experimental period of 21 days. In the control (C) group, cows grazed a Pennisetum clandestinum pasture and were supplemented with a commercial concentrate according to milk production. In the Met-Lys treatment, cows received the same ration supplemented with protected Lys and Met. Milk yield and composition and milk protein profile were measured at the start and the end (21st day) of the experimental period. The Tricine-SDS-PAGE and the Gel-Quant Express Analysis (Invitrogen) software were used to determine milk protein composition. Statistical analysis was performed using the SAS’s PROC MIXED procedure through a mixed model that included the animal as a random effect and the treatments as a fixed effect adjusted by covariables. Milk production averaged 23.7 (±2.0) kg cow-1 day-1 without differences between treatments (P < 0.96). Yield of fat corrected milk (4% FCM) tended (P < 0.10) to increase in the Met-Lys treatment (26.0 kg cow-1 day-1) compared to C (24.2 kg cow-1 day-1). Milk protein content (g/kg) did not differ (C = 30.4; Met-Lys = 31.1) and lactose content tended (P < 0.08) to be higher in the Met-Lys (47.4) group compared to C (45.9). Milk protein content (g/kg) of αS1-CN resulted higher (P < 0.046) in Met-Lys (10.58) compared to C (9.44). Concentration of β-CN also increased (
Alternativas de biofertilización para la producción sostenible de cebolla de bulbo (Allium cepa) en Cucaita, Boyacá
Méndez,Martha; Viteri,Silvio;

Abstract: the objective of this study was to validate the potential of four biofertilizing alternatives for onion bulb production in cucaita, boyaca, colombia. the treatments evaluated were: 1) bocashi-hen manure, super broth 4, and fertilizer, 2) bocashi-cow manure, super broth 4, and fertilizer, 3) bocashi-hen manure, super broth 4, rhizosphere broth, and fertilizer, 4) bocashi-cow manure, super broth 4, rhizosphere broth, and fertilizer, 5) chemical control, and 6) absolute control. the experimental design was a random complete block with six treatments and four replications. the variables determined were: ′disease incidence′, ′bulb number′, ′disease unaffected bulb weight′, ′disease affected bulb weight′, ′total bulb weight′, and ′bulb diameter′. the results indicated that the bocashis as well as the super 4 and rhizosphere broth contributed to the soil with a great amount and diversity of beneficial microorganisms, which were important for the equilibrium in plant nutrition and plant defence against pathogens. the lowest disease incidence was obtained in the treatments bocashi-hen manure, super broth 4, fertilizer and bocashi-cow manure, super broth 4, rhizosphere broth, fertilizer. in relation to the production variables, though none of the biofertilizing alternatives resulted significantly different to the chemical control, those which include bocashi, super broth 4, rhizosphere broth, and an adequate rate of chemical fertilizer are considered the most promissory because in addition to produce results similar to those obtained with the conventional technique of the farmer since the beginning they have a microbiological and chemical potential which is essential for the sustainability of the production and the environmental quality in the future.

Abstract: Antibacterial activity of methanol, n-hexane and water extracts of seeds and bark of Moringa oleifera and Moringa ovalifolia was conducted. The causative agents of common bacterial infections that are thought to cause water-borne diseases, namely, Escherichia coli, Enterococcus faecalis, and Bacillus cereus were chosen for the study. The paper-disc diffusion method was used with treatments arranged in a completely randomized design and replicated four times. The M. oleifera extracts showed more inhibitory effect than those of M. ovolifolia. The conventional antibiotic Ampicilin generally showed higher inhibitory effect than the extracts of both M. oleifera and M. ovalifolia. The inhibitory effect varied depending on the solvent used. The n-hexane extracts of both seeds and bark of M. ovalifolia and M. oleifera had almost the same inhibition activities (6 ± 1 mm mean inhibition zones) on B. cereus, E. coli

Abstract: Based on prior research, we hypothesized that staff in an outpatient clinic caring for an HIV patient population might rely on religious and spiritual frameworks to cope with the strains of their work and that their responses to a spiritual and religious survey might reflect work-related spiritual distress. Surveys were completed by 78.7% of staff (n = 59). All respondents scored in the "moderate" range for religious and spiritual well-being as well as existential satisfaction with living. The large majority agreed that the religious and spiritual concerns of patients have a place in patient care. Nurses, (88.2% of nurse respondents) viewed assessing the spiritual needs of patients as their responsibility, (p = 0.03). While 82% of HIV clinic respondents privately prayed for patients always, often or sometimes, this did not include physicians. Physicians in this clinic setting appeared to be less spiritual and religious, based on their survey responses, than coworkers and than US physicians in general. The majority of clinic physicians (78%) believed that God does not suffer with the suffering patients, in contrast to the majority of support staff (69%) and nearly half of the nurses, who believed that God does suffer with them, (p = 0.018). Contrary to our expectation, respondents did not report work-related spiritual distress, which may be related to improved therapies that can prolong and improve patients’ lives. Survey data revealed, however, a surprising level of engagement in and reliance on spiritual and religious frameworks among nurses and support staff. Whether the absence of measured spiritual distress is linked, in a causal rather than random manner, to spiritual and religious reliance by certain of these health care providers, is unknown.
The Effect of Synovial Fluid Enzymes on the Biodegradability of Collagen and Fibrin Clots

Materials , 2011, DOI: 10.3390/ma4081469
Abstract: Recently there has been a great deal of interest in the use of biomaterials to stimulate wound healing. This is largely due to their ability to centralize high concentrations of compounds known to promote wound healing at a needed location. Joints present a unique challenge to using scaffolds because of the presence of enzymes in synovial fluid which are known to degrade materials that would be stable in other parts of the body. The hypothesis of this study was that atelocollagen scaffolds would have greater resistance to enzymatic degradation than scaffolds made of gelatin, fibrin and whole blood. To test this hypothesis, collagen and fibrin-based scaffolds were placed in matrix metallopeptidase-1 (MMP-1), elastase, and plasmin solutions at physiologic concentrations, and the degradation of each scaffold was measured at varying time points. The atelocollagen scaffolds had a significantly greater resistance to degradation by MMP-1, elastase and plasmin over the fibrin based scaffolds. The results suggest that atelocollagen-based scaffolds may provide some protection against premature degradation by synovial fluid enzymes over fibrin-based matrices.

Abstract: seasonal temporary workers rebuilding migration projects every year arrive to fruit harvest in the valleys of rio negro. to this end, we characterize the spaces of life and work as migration contexts, their family histories and occupational trajectories. the analytical perspective is to visualize them from family social reproduction strategies and to focus on migration projects as one of its own elements. this study can be enrolled in the line of empirical research and theoretical conceptualization on the territorial mobility of workers and the expansion of capital in export agricultural regions. after successive approximations by extensive, typological and comparative procedures, we understand that the study could be enriched by the incorporation of social insights on two histories of life, paradigmatic it is one by its points of anchorage between family history and agrarian social history but both are representative of migratory harvest flows and involve two or three generations of workers. in them, we analyze the mutual relations between labor trajectories, space itineraries and family dynamics. we deepen in vital and occupational trajectories in their historical travesties and space itineraries. critical perspective and empirical data redefine seasonal work in agriculture and the character that migration process assumes in dynamic regions of dependent capitalism. workers movements show different levels of territories but also express paradoxical modernization with persistence of marginalization in subalternization.
