Extreme environments Morrope and Bayovar Salt lagoons, several ecosystems and microhabitats remain unexplored, and little is known about the diversity of Actinobacteria. We suggest that the endemic bacteria present in this extreme environment is a source of active molecules with anticancer, antimicrobial, and antiparasitic properties. Using phenotypic and genotypic characterization techniques, including 16S rRNA sequencing, we identified these bacteria as members of the genera Streptomyces, Pseudonocardia, Staphylococcus, Bacillus, and Pseudomonas.

The Lulun Project incorporated a social marketing strategy that accompanied a randomized controlled trial (RCT) of a food-based intervention that introduced eggs into the complementary feeding diet of Ecuadorian infants. This strategy was designed to promote behaviour change, in this case, egg consumption, through voluntary prosocial behaviour, empowerment, and brand loyalty. A three-phase social marketing strategy (design, campaigns, and evaluation) contributed to our successful RTC by applying techniques drawn from marketing, publicity, design, and communications.

The aim of this study was to analyze the psychometric properties of the Purpose-In-Life Test (PIL), as well as the age-related differences in meaning in life in women diagnosed with eating disorders. Participants were 250 Spanish women diagnosed with eating disorders who ranged from 12 to 60 years old. Confirmatory Factor Analysis, descriptive analyses, estimation of the internal consistency of the PIL, correlations between the PIL and the Beck Hopelessness Scale (BHS), Overweight Preoccupation Scale (OPS), and Body Investment Scale (BIS), and age differences were calculated.

Recent years have seen a growing interest in Berberine, a phytochemical with multispectrum therapeutic activities, as anti-tumoral agent for photodynamic therapy (PDT). In this context, low density lipoproteins (LDL) play a key role in the delivery of the photosensitizer in tumor cells. We correlate the physicochemical parameters of the berberine association to LDL with the influence of LDL-delivery on its accumulation in a glioma cell line and on its photo-induced activity in view of antitumor PDT.

The effective distribution of affinities (Conditional Affinity Spectrum, CAS) seen by a metal ion binding to a humic substance under natural water conditions is derived and discussed within the NICA-Donnan model. Analytical expressions for the average affinity of these distributions in general multi-ion mixtures are reported here for the first time. These expressions enable a simple evaluation of the effect of all interfering cations on the affinity distribution of a given one.

Stepwise constants can be used to describe competitive proton and metal binding to macromolecules with a large number of sites. With the aim of accessing information on the microscopic binding model, we report an expression that connects the stepwise constants to the site-specific metal constants. This expression holds for a very general complexation model including heterogeneity, interactions, and chelate complexation.

This work presents a new methodology aimed at obtaining the stepwise stability constants corresponding to the binding of ions (or other small molecules) to macromolecular ligands having a large number of sites. For complexing agents with a large number of sites, very simple expressions for the stepwise stability constants arise. Such expressions are model-independent; that is, they allow the determination of the stepwise stability constants without making any previous assumption of the detailed complexation mechanism.

The degree of lability of a given metal complex species is modified in the presence of a mixture of ligands. This modification is a consequence of the coupling of the association and dissociation processes of all of the complexes according to the competitive complexation reaction scheme. We show that, because of the mixture effect, the lability of a given complex usually increases when another more labile complex is added into the system, while it decreases upon addition of a less labile one.

The rigorous analytical solution for the fluxes from a mixture of 1:1 metal complexes toward an active surface under steady-state planar diffusion in a finite domain and excess ligand conditions allows for the computation of the global degree of lability of the system as well as particular degrees of lability of each complex in the mixture. This kind of system is found in a variety of fields ranging from electrochemical techniques (such as stripping chronopotentiometry at scanned deposition potential, SSCP) to analytical devices (such as diffusion gradients in thin-film gels, DGT). Among the specific effects arising from the presence of a mixture of ligands competing for the metal we highlight the following: (i) The degree of lability of a complex in the mixture differs from its degree of lability in an unmixed system with the same ligand concentration, and (ii) the degree of lability of one complex depends on (i.

Solid organ transplant may be the only therapeutic alternative in some HIV-infected patients. Experience in North America and Europe during the last five years shows that survival at three years after an organ transplant is similar to that observed in HIV-negative patients. The criteria agreed upon to select HIV patients for transplant are: no opportunistic infections (except tuberculosis, oesophageal candidiasis or P.

Studer's ortothopic neobladder after radical cistectomy has become a good alternative and has improved the patients' quality of life. Voiding dysfunction after surgery is one of the possible late complications with incomplete emptying of the neobladder and chronical urinary retention. The mechanical obstruction may be due to recurrence of the tumor, anterior vaginal wall prolapse, urethrointestinal anastomosis stricture, mucose plug, stone and mucosal fold.

Conservative treatment of the transitional cell carcinoma of the upper urinary tract by ureteroscopy is currently a therapeutic approach which is accepted by urologists. Recurrences are frequent (0-65%), as well as in bladder tumors; the longer the follow-up of the series the higher the recurrence. Multifocality, history of bladder tumor or renal pelvis localization are prognostic factors for recurrence.
