BACKGROUND Suicide is a leading cause of preventable death worldwide,with its peak of maximum incidence in later life.Depression often puts an individual at higher risk for suicidal behaviour.In turn,depression deserves particular interest in old age due to its high prevalence and dramatic impact on health and wellbeing.AIM To gather integrated evidence on the potential risk factors for suicide behaviour development in depressive older adults,and to examine the effects of depression treatment to tackle suicide behaviour in this population.METHODS A systematic review of empirical studies,published from 2000 onwards,was conducted.Suicidal behaviour was addressed considering its varying forms(i.e.,wish to die,ideation,attempt,and completed suicide).RESULTS Thirty-five papers were selected for review,comprising both clinical and epidemiological studies.Most of studies focused on suicidal ideation(60%).The studies consistently pointed out that the risk was related to depressive episode severity,psychiatric comorbidity(anxiety or substance use disorders),poorer health status,and loss of functionality.Reduced social support and loneliness were also associated with suicide behaviour in depressive older adults.Finally,the intervention studies showed that suicidal behaviour was a robust predictor of depression treatment response.Reductions in suicidal ideation were moderated by reductions in risk factors for suicide symptoms.CONCLUSION To sum up,common and age-specific risk factors seem to be involved in suicide development in depressive older adults.A major effort should be made to tackle this serious public health concern so as to promote older people to age healthily and well.

Background:Black alder(Alnus glutinosa)forests are in severe decline across their area of distribution due to a disease caused by the soil-borne pathogenic Phytophthora alni species complex(class Oomycetes),“alder Phytopththora”.Mapping of the different types of damages caused by the disease is challenging in high density ecosystems in which spectral variability is high due to canopy heterogeneity.Data obtained by unmanned aerial vehicles(UAVs)may be particularly useful for such tasks due to the high resolution,flexibility of acquisition and cost efficiency of this type of data.In this study,A.glutinosa decline was assessed by considering four categories of tree health status in the field:asymptomatic,dead and defoliation above and below a 50% threshold.A combination of multispectral Parrot Sequoia and UAV unmanned aerial vehicles-red green blue(RGB)data were analysed using classical random forest(RF)and a simple and robust three-step logistic modelling approaches to identify the most important forest health indicators while adhering to the principle of parsimony.A total of 34 remote sensing variables were considered,including a set of vegetation indices,texture features from the normalized difference vegetation index(NDVI)and a digital surface model(DSM),topographic and digital aerial photogrammetry-derived structural data from the DSM at crown level.Results:The four categories identified by the RF yielded an overall accuracy of 67%,while aggregation of the legend to three classes(asymptomatic,defoliated,dead)and to two classes(alive,dead)improved the overall accuracy to 72% and 91% respectively.On the other hand,the confusion matrix,computed from the three logistic models by using the leave-out cross-validation method yielded overall accuracies of 75%,80% and 94% for four-,three-and two-level classifications,respectively.Discussion:The study findings provide forest managers with an alternative robust classification method for the rapid,effective assessment of areas affected and non-affected by the disease,thus

The aim of this paper is to determine the role of enzymatic vitrectomy performed by intravitreal injection of autologous plasmin enzyme(APE)in the management of diabetic retinopathy and diabetic macular edema(DME).Diabetic patients with proliferative diabetic retinopathy or DME and evident posterior hyaloid adherence to the retinal surface were included.All cases were treated with an initial intravitreal injection of APE and reevaluated one month later,measuring changes in best-corrected visual acuity(BCVA),macular thickness and the status of the posterior hyaloid.A second APE injection was performed in cases with no evident posterior vitreous detachment(PVD)after the initial treatment.Sixty-three eyes were included in the present review.A complete PVD appeared in 38%of cases(24 eyes)after one injection of plasmin and the total increased to 51%(32 eyes)after the second injection,separated at least by one month.The central macular thickness improved in all cases(100%)and BCVA in89%.Finally,in 50%of eyes with proliferative diabetic retinopathy,a high reduction of new vessels regression was observed.Enzymatic vitrectomy could be considered a good therapeutic alternative in diabetic retinopathy and macular edema.

The balance between cell proliferation and cell growth characterizes tissue homeostasis on one side and cell death on the other side. Fas receptor-mediated apoptosis is a control mechanism for tissue homeostasis, and avoiding this death pathway predisposes to many human diseases, including cancer. Current therapies for this disease are invasive and do not have the desired effect in the control of the disease. In this context, the search for new drugs that contribute to a better treatment is gaining more relevance. 4-tert-butyl-bis-(2,6-thiomorpholin-4-ylmethyl)-1-phenol (LQM319) [1,2] is a drug currently in preclinical stage, and we have shown that it has a hypertensive effect, similar to captopril, in a hypertensive rat model. Different studies have shown that some chemicals that are used as antihypertensive agents have an antineoplastic effect against certain types of cancer, as is the case of hydralazine [3], and captopril [4], among others [5]. On the other hand, it has been reported that morpholine derivatives may activate Fas (CD95)-mediated apoptosis. The aim of the present study was to show the interaction between CD95 (receptor) and thiomorpholine derivatives (ligand) using molecular modeling and docking studies, and to elucidate the possible action mechanism of 4-tert-butyl-bis-(2,6-thiomorpholin-4-ylmethyl)-1-phenol.

We analyzed the allelic and genotypic frequencies of the glutathione-S-transferase P1 （GSTPI） rs1695 single nucleotide polymorphism （SNP） in 290 patients with multiple sclerosis （MS） and in 310 healthy controls. We found no significant association between the rs1695 variant and MS. Among MS patients, there was no relationship between the rs1695 variant and either gender, clinical type of MS or the age of onset of MS.

The effect of the administration of large amounts of green tea polyphenols is a matter of controversy. We explored whether a polyphenol mixture from a concentrated green tea extract (Polyphenon 60) could alter the effects on mice of the type 2 (two chains) ribosome-inactivating protein nigrin b isolated from Sambucus nigra L. Nigrin b triggers specific reversible toxic effects on the mouse intestines featured by apoptosis of mice Lieberkühn crypt cells upon parenteral administration of sub-lethal amounts. Independent administration to mice of 30 mg/kg body weight of Polyphenon 60 by oral gavage or 10 mg/kg body weight of nigrin b administered via the intraperitoneal route (i.p.) did not affect survival. In contrast, the simultaneous treatment greatly enhanced nigrin b toxicity leading to the death of some animals. The histological analysis revealed that the most serious injury was inflicted on the small intestine crypts, which disappeared, and on the liver, which evidenced hepatotoxicity showing haemorrhagic areas. These findings raise concerns about the abuse of high concentrations of green tea polyphenols especially when the intestinal mucosa is damaged, for instance by toxins or therapeutic drugs.

Chemically based rodent models are used to assess the positive effects promoted by foods and gut microbiota on gut health. Lectins with enzymatic activity, such as type 2 ribosome-inactivating proteins, might also prove useful for exploring these issues. Sub-lethal doses of the lectin nigrin from Sambucus nigra L. to mice promoted reversible derangement of gut epithelium by induction of apoptosis of transit amplifying cells of the small intestine crypts in a time-dependent course. The present work seeks to study vitamin B6 accumulation in plasma from an oral bolus in a mouse nigrin model. 24 h after sub-lethal nigrin b treatment, there was clear body weight reduction associated to a notable increase in Evan’s blue stain accumulation in excised small intestine, an increase in myeloperoxidase activity, and a near 50% reduction in plasma accumulation of vitamin B6. Histological analysis of small intestine sections of nigrin b-treated animals also revealed significant derangement of intestinal crypts. Seventy two hours after nigrin b treatment, stain uptake decreased and vitamin B6 accumulation was almost restored despite villi derangement. Large intestine crypts were scarcely or not at all affected. Eight days after nigrin b treatment, vitamin B6 uptake and intestinal crypt structure had fully recovered. The nigrin b mice model supports the view that, under these conditions, the carrier-mediated vitamin B6 uptake component of the small intestine crypts is probably the most active when the vitamin is administered orally as a bolus. The findings provide insights into the suitability of the present mice model for nutritional or drug absorption studies in conditions of partially altered or injured intestinal mucosa.
