Immunobiotic and Paraprobiotic Potential Effect of in a Systemic Toxoplasmosis Murine Model.

One of the main characteristics of probiotics is their ability to stimulate and modulate the immune response regardless of their viability. (Lc) can stimulate local and systemic immunity, in addition to the activation of macrophages at sites distant from the intestine. Activated macrophages limit the replication of intracellular protozoa, such as , through the production of nitric oxide.

Steam roller maneuver in pneumatic retinopexy. Does it work?

Objective: To identify the efficacy and safety of the steam-roller maneuver, in patients treated with pneumatic retinopexy.

Method: Experimental, prospective, comparative, longitudinal study in patients with retinal detachment, treated with pneumatic retinopexy. Patients were assigned to one of two groups: without steam roller maneuver (group 1) or with it (group 2).

Dexamethasone implant in silicone oil: in vitro behavior.

Background: To determine the effect of the silicone on the dexamethasone intravitreal implant.

Methods: Basic, experimental, prospective and transversal study performed at the hospital "Nuestra Señora de la Luz" in Mexico City. One dexamethasone implant was placed in a test tube with 4 mL of each tamponade medium: 1000cS, 5000cS and heavy silicone oil; basic saline solution was used as the control medium.

Defensin production by human limbo-corneal fibroblasts infected with mycobacteria.

Epithelial cells of the cornea and the conjunctiva constitutively produce antimicrobial peptides; however, the production of defensins by other cell types located around the eye has not been investigated. We analyzed the production of beta-defensins (hBD) and cathelicidin LL-37 during the infection of primary limbo-corneal fibroblasts with M. tuberculosis (MTB), M.

[Down regulation of IL-8 and IL-6 in human limbal epithelial cells cultured with human dialyzable leukocyte extracts].

Introduction: Human Limbal Epithelial Cells (hLEC) are stem cells that give rise to corneal epithelium. After corneal damage, hLEC produce large amounts of IL-8 and IL-6, inducing inflammation in cornea and conjunctiva. Despite inflammation is necessary to repair the ocular surface since this process may be potentially harmful and could lead to corneal opacity.

[In vitro phenotypic characterization of human limbal epithelial cells].

Introduction: Human limbal epithelial cells (huLEC) have been used for clinical purposes in ocular surface diseases to promote rapid re-epithelisation and restore corneal epithelium integrity. However, in Mexico this technique has not been fully developed. This study was conducted to characterize the huLEC phenotype expanded in vitro using a cell culture technique.
