Associations between dietary diversity and self-rated health in a transverse study of four local food systems (French Guiana, Guadeloupe, Portugal and Senegal).

Background: The nutrition transition is linked to the double-burden of malnutrition worldwide, and its impact on the quality of life is considerable. The dietary diversity score and self-rated health are two proxies that have been used to assess, for the former, nutrient adequacy and overall diet quality, and for the latter, health from a sociological, epidemiological and economical lens. The general aim of this study was to evaluate the relation between food and subjective health, and to test the hypothesis that greater dietary diversity is positively associated with a better perception of health.

Bone Marrow Mesenchymal Stem Cells Promote Repairing the Bruised Tissue via Regulating mRNA Expression of Molecular Biomarkers and the Apoptotic Rate.

Background/aims: Bruise is the extravasation of blood that may be mild or severe. Bone marrow mesenchymal stem cells (BM-MSCs) are one of the most promising cells used in regenerative medicine for treating many disorders. We aimed to evaluate the efficiency of BM-MSCs in treating cutaneous bruises.

Deltamethrin and Its Nanoformulations Induce Behavioral Alteration and Toxicity in Rat Brain through Oxidative Stress and JAK2/STAT3 Signaling Pathway.

Deltamethrin (DM) is the most powerful synthetic pyrethroid that has toxicity to the central nervous system and results in behavioral changes in both animals and humans. This effect is mediated by inducing alterations in the action of neurotransmitters and brain pathological changes. Nanocarrier encapsulated pesticides may decrease the toxicity of pesticides.

Therapeutic effect of mesenchymal stem cells on histopathological, immunohistochemical, and molecular analysis in second-grade burn model.

Background And Aim: Deleterious cutaneous tissue damages could result from exposure to thermal trauma, which could be ameliorated structurally and functionally through therapy via the most multipotent progenitor bone marrow mesenchymal stem cells (BM-MSCs). This study aimed to induce burns and examine the effect of BM-MSCs during a short and long period of therapy.

Material And Methods: Ninety albino rats were divided into three groups: group I (control); group II (burn model), the animals were exposed to the preheated aluminum bar at 100°C for 15 s; and group III (the burned animals subcutaneously injected with BM-MSCs (2×10 cells/ ml)); they were clinically observed and sacrificed at different short and long time intervals, and skin samples were collected for histopathological and immunohistochemical examination and analysis of different wound healing mediators via quantitative polymerase chain reaction (qPCR).

Carcinogenic effect of potassium octatitanate (POT) fibers in the lung and pleura of male Fischer 344 rats after intrapulmonary administration.

Background: Potassium octatitanate fibers (KO•8TiO, POT fibers) are used as an asbestos substitute. Their physical characteristics suggest that respirable POT fibers are likely to be carcinogenic in the lung and pleura. However, previous 2-year inhalation studies reported that respired POT fibers had little or no carcinogenic potential.

Pulmonary and pleural toxicity of potassium octatitanate fibers, rutile titanium dioxide nanoparticles, and MWCNT-7 in male Fischer 344 rats.

Potassium octatitanate (KO·8TiO, POT) fibers are used as an alternative to asbestos. Their shape and biopersistence suggest that they are possibly carcinogenic. However, inhalation studies have shown that respired POT fibers have little carcinogenic potential.

Potassium octatitanate fibers induce persistent lung and pleural injury and are possibly carcinogenic in male Fischer 344 rats.

Potassium octatitanate fibers (K O·8TiO , POT fibers) are widely used as an alternative to asbestos. We investigated the pulmonary and pleural toxicity of POT fibers with reference to 2 non-fibrous titanium dioxide nanoparticles (nTiO ), photoreactive anatase (a-nTiO ) and inert rutile (r-nTiO ). Ten-week-old male F344 rats were given 0.
