Smart Portable Device Based on the Utilization of a 2D Disposable Paper Stochastic Sensor for Fast Ultrasensitive Screening of Food Samples for Bisphenols.

Since the determination of the high toxicity of bisphenol A, alternative structures for bisphenols have been synthesized, resulting in bisphenols C, E, F, S, and Z. These bisphenols have replaced bisphenol A in plastic bottles, toys, and cans used for preserving food. Later, the toxicity and negative effects of all of these bisphenols on people's health were proven.

The influence of foreign body surface area on the outcome of chronic osteomyelitis.

Reproducible animal models of osteomyelitis close to the clinical scenario are difficult to obtain as the animals either die shortly after inoculation of bacteria or the bone cures itself of infection. Additional materials used as foreign bodies offer increased chances for localized infection due to bacterial attachment and are closer to clinical pathology. Through in vivo experimentation we investigated here the influence of surface area of a series of foreign bodies on the final outcome of the animal model, in terms of reproducibility, survival rate and time necessary for onset of chronic disease.

A CASE OF POLYMYOSITIS WITH INTERSTITIAL LUNG DISEASE ONSET.

Polymyositis is an idiopathic inflammatory myopathy of unknown aetiology that affect skeletal muscles causing symmetrical, proximal muscle weakness, and also other internal organs. The investigations reveal elevated skeletal muscle enzyme levels and characteristic electromyography (EMG) and muscle biopsy findings. Pulmonary involvement in polymyositis includes respiratory muscle weakness, aspiration pneumonia, interstitial lung disease, infection and drug-induced pneumonia.

The effects of some Curdlan derivatives on Dectin-1 expression and cytokine production in human peripheral blood mononuclear cells.

The cells of immune system such as monocytes and macrophages are in first line defence against dangerous signals. In the present paper the recognition of Dectin 1 receptors and the modulation of Interleukin-10 (IL-10) and Tumor Necrosis Factor-alpha (TNF-alpha) cytokine production by Curdlan and Curdlan derivatives in peripheral blood mononuclear cells (PBMCs) were studied. The effect of Curdlan or Curdlan derivatives on the expression of Dectin 1 receptors in PBMCs was revealed by flow-cytometry and the levels of IL-10 and TNFalpha were measured by ELISA kit in supernatants of PBMCs cultured in presence or absence of Curdlan, Curdlan derivatives and LPS.

Curdlan derivatives able to enhance cytostatic drugs activity on tumor cells.

The chemotherapy success to kill cancer cells depends on its ability to stop cell division. The faster the cells are dividing, the more likely it is that chemotherapy will kill the cells, causing the tumor to shrink. Taking into account the severe side effects of chemotherapy, drugs producers also focus on natural products obtained either from medicinal plants, or from microorganisms.

Recognition and modulation of Dectin-1 and TLR-2 receptors by curdlan derivatives and purified natural extracts.

Toll-like receptors (TLRs) and Dectin-1, as members of Pattern Recognition Receptors play an essential role in innate immune response against bacteria and fungi respectively, contributing to pathogens recognition, phagocytosis, etc. Dectin-1 and TLR-2/TLR-6 can interact for intracellular signal transduction. Dectin-1 is expressed at low levels on macrophages and at high levels on dendritic cells.

The modulation of reactive oxygen species production from human polymorphonuclear cells by curdlan derivatives as dectin-1 agonists/antagonists.

Reactive oxygen species (ROS) are well known to be cytotoxic and have been implicated in the etiology of a wide array of human diseases including diabetes, neurodegenerative diseases, cancer and also influence central cellular processes such as proliferation, apoptosis, senescence etc. If in these pathological or degenerative conditions characterized by free radicals excess, reactive species are not eliminated, they can maintain destructive processes, already initiated at different cellular levels. Understanding the role of ROS as key mediators in signaling cascades may provide various opportunities for pharmacological intervention.

Study of apoptosis induced by cytostatics and vegetal extracts on human endothelial cell line.

Angiogenesis, the biological process by which new capillaries are formed from pre-existing vessels, is a tightly controlled and complex process involving several factors with both stimulating and inhibiting steps. In solid tumor growth, a specific clinical turning point is the transition to the vascular phase. Once it develops an intrinsic vascular network, a tumor grows indefinitely.

[Septic pylephlebitis with detection of gas in the portal vein: a rare complication of sigmoid diverticulitis].

Pylephlebitis, septic thrombosis of the portal vein and its branches, is an infrequent complication of intra-abdominal inflammatory processes which may lead to thrombosis of the portal vein or to liver abscesses. Air in the protal venous system usually predicts a fatal outcome. The survival rate calculated in all reported cases is less than 25%.
