Does Vitamin D Insufficiency Influence Prebiotic Effect on Calcium Absorption and Bone Retention?

Higher calcium (Ca) absorption would partially compensate for Ca intake below requirements for bone health. Previously, we found that GOS/FOS prebiotic mixture (PM) increases Ca absorption in the colon and retention in bone. Ca absorption and retention are regulated by vitamin D (VD).

Window Approach for Simultaneous Root Fragment Removal and Implant Placement: Two Case Reports.

Introduction: Root fracture during extraction is not uncommon due to the presence of multiple and thin roots, which are often divergent and curved. The retained root fragments (RF) are usually radiographic incidental findings and often asymptomatic without associated pathology. However, careful and conservative surgical strategies for the removal of RF must be incorporated to allow for simultaneous implant placement and to avoid potential complications such as compromised osseointegration or retrograde peri-implantitis.

Development of physical activity and food built environment quality indicators for chronic diseases in Argentina.

Although obesity and non-communicable disease (NCD) prevention efforts to-date have focused mainly on individual level factors, the social and physical environments in which people live are now widely recognized as important social determinants of health. Obesogenic environments promote higher dietary energy intakes and sedentary behaviors, thus contributing to the obesity/NCD burden. To develop quality indicators (QIs) for measuring food and physical activity (PA)-built environments in municipalities.

Aminobisphosphonate-treated ewes as a model of osteonecrosis of the jaw and of dental implant failure.

Background: Bisphosphonate (BP)-related osteonecrosis of the jaw (BRONJ) and dental implant failure are two negative side effects of chronic aminoBP treatment.

Methods: Eleven ovariectomized (OVX) ewes and four ewes subjected to sham surgery (SHAM) were treated as follows: OVX (n = 5): OVX plus saline solution; zoledronic acid-treated group (ZOL) (n = 6): OVX plus ZOL; SHAM (n = 4): SHAM plus saline solution. Extraction of the first upper molar was performed at 1 year, dental implant placement at 2 years, and sacrifice at 28 months.

Collective health and regional integration in Latin America: An opportunity for building a new international health agenda.

From its origins, the Latin American Social Medicine and the Collective Health (LASM/CH) movements have focused on thinking about health from and for the region. After the implementation of neoliberal policies, social improvements and the geopolitical strengthening of the region became the roots of new regional integration projects in South America. The objective of this article is twofold.

Effect of Adding a Galacto-Oligosaccharides/Fructo-Oligosaccharides (GOS/FOS®) Mixture to a Normal and Low Calcium Diet, on Calcium Absorption and Bone Health in Ovariectomy-Induced Osteopenic Rats.

Menopause is associated with bone loss. Prebiotics increase Ca, inorganic phosphorus (Pi), and Mg absorption, improving bone health. These increases would supply an extra amount of minerals, decreasing bone resorption and possibly reversing ovariectomy-induced bone loss.

Data on litter quality of host grass plants with and without fungal endophytes.

Certain Pooideae species form persistent symbiosis with fungal endophytes of Epichloë genus. Although endophytes are known to impact the ecology and evolution of host species, their effects on parameters related with quality of plant biomass has been elusive. This article provides information about parameters related with the quality of plant litter biomass of two important grass species (Schedonorus phoenix and Schedonorus pratensis) affected by the symbiosis with fungal endophytes (Epichloë coenophiala and Epichloë uncinata, respectively).

Effect of a mixture of GOS/FOS on calcium absorption and retention during recovery from protein malnutrition: experimental model in growing rats.

Introduction: During growth, protein deprivation impairs epiphyseal growth plate (EGP) height, bone volume (BV) and endochondral ossification. During catch-up growth, Ca availability becomes essential to ensure the extra amount needed to achieve optimal peak bone mass and strength. GOS and FOS improve mineral absorption in the colon.

A study of the effect of dietary fiber fractions obtained from artichoke (Cynara cardunculus L. var. scolymus) on the growth of intestinal bacteria associated with health.

The effect of different fractions enriched in soluble fiber obtained from artichoke using citric acid or citric acid/hemicellulase on the selective growth of Lactobacillus plantarum 8114 and Bifidobacterium bifidum ATCC 11863 was evaluated. Gompertz modeling of Lactobacillus plantarum 8114 growth showed a higher specific growth rate (μ: 0.16 h(-1)) in the presence of fractions isolated from stems using hemicellulase (fraction A) than in the presence of glucose (μ: 0.

Protease and hemicellulase assisted extraction of dietary fiber from wastes of Cynara cardunculus.

The action of protease and hemicellulase for the extraction of fractions enriched in soluble fiber from bracts and stems of Cynara cardunculus was evaluated. Using a two-factor simplex design comprising protease amounts of 0-200 μL and hemicellulase amounts of 0-200 mg for 5 g of material, we explored the effect of a 5 h enzymatic treatment at 40 °C on the chemical composition and yield of the fractions isolated. The fractions contained inulin and pectin.

Oral health in young women having a low calcium and vitamin D nutritional status.

Objective: Oral health plays an important role in an individual's eating choices, which in turn ensure good nutrition throughout life. The deterioration in diet quality may partially explain the association between tooth loss and several systemic diseases, including osteoporosis. The study evaluated the association between oral health and calcium (Ca) and vitamin D nutritional status.

Effect of a combination GOS/FOS® prebiotic mixture and interaction with calcium intake on mineral absorption and bone parameters in growing rats.

Aim: Increasing calcium intake is the most effective strategy for avoiding Ca deficit. However, if intake remains inadequate, improving Ca absorption becomes an important tool to optimize Ca homeostasis and bone health.

Purpose: The effect of a mixture of GOS/FOS(®) 9:1 added to a normal- or low-Ca diets on Ca absorption and bone mineralization, density and structure was investigated, in a model of growing rats.

Upgrading of residues of bracts, stems and hearts of Cynara cardunculus L. var. scolymus to functional fractions enriched in soluble fiber.

Since only the central portion of the immature flowers of artichoke (Cynara cardunculus L. var. scolymus) is consumed (<20%) it is interesting to upgrade its residues to render value added products.

Biopolymeric antimicrobial films: study of the influence of hydroxypropyl methylcellulose, tapioca starch and glycerol contents on physical properties.

Mixture design methodology was applied to study the effect of different levels of tapioca starch (TS), hydroxypropyl methylcelullose (HPMC), and glycerol (Gly) on the physical properties of biopolymeric films supporting potassium sorbate (KS; 0.3% w/w) with the goal of contributing to the development of materials for preventing food surface contamination. Mechanical properties, water vapour permeability (WVP), solubility in water (S) and colour attributes were evaluated on the films.

Low dietary calcium and obesity: a comparative study in genetically obese and normal rats during early growth.

Purpose: A low calcium intake (LCaI) may predispose to obesity, and excessive fat mass may be detrimental to bone. The impact of Ca inadequacy would be greater in subjects predisposed to obesity. LCaI effect on obesity development during the rapid growth period was compared in two strains of rats: spontaneously obese IIMb/β (O) and Wistar (W).

Psychiatric disorders in patients with psychogenic nonepileptic seizures and drug-resistant epilepsy: a study of an Argentine population.

Epidemiological data show that up to 20-30% of patients with psychogenic nonepileptic seizures (PNESs), resembling drug-resistant epilepsy (DRE), are referred to tertiary epilepsy centers. Furthermore, both disorders present high psychiatric comorbidity, and video-EEG is the gold standard to make differential diagnoses. In this study, we described and compared the clinical presentation and the frequency of psychiatric disorders codified in DSM IV in two groups of patients, one with PNESs and the other with DRE, admitted in a tertiary care epilepsy center of Buenos Aires, Argentina.
