Capsaicin short term administration effect on different immune parameters.

Type 1 diabetes is an autoimmune disease affecting a higher and higher number of persons; for this reason, the study of diabetes, and its complications, has shown a major interest. In order to highlight the modifications appeared in this disease, it is essential to use a suitable model. In "Cantacuzino" NIRDMI there is a double transgenic murine model which develops a fulminating form of type 1 diabetes.

Double transgenic mice--a suitable model for studying oxidative stress in type 1 diabetes mellitus.

Type 1 diabetes mellitus (T1DM), one of the most prevalent chronic diseases is characterized by the progressive destruction of pancreatic beta cells, leading to insulin deficiency and hyperglycemia. Studies performed on diabetic subjects with prolonged hyperglycemia showed the oxidative stress occurrence followed by molecular, cellular and tissue damage. Currently, reducing the oxidative stress represents a therapeutic target, in order to reduce its complications in diabetic patients.

Advanced type 1 diabetes is associated with ASIC alterations in mouse lower thoracic dorsal root ganglia neurons.

Acid-sensing ion channels (ASICs) from dorsal root ganglia (DRG) neurons are proton sensors during ischemia and inflammation. Little is known about their role in type 1 diabetes (T1D). Our study was focused on ASICs alterations determined by advanced T1D status.

TRPV1 properties in thoracic dorsal root ganglia neurons are modulated by intraperitoneal capsaicin administration in the late phase of type-1 autoimmune diabetes.

Pharmacological therapies in type 1 diabetes for efficient control of glycemia and changes in pain alterations due to diabetic neuropathy are a continuous challenge. Transient receptor potential vanilloid type 1 (TRPV1) from dorsal root ganglia (DRG) neurons is one of the main pharmacological targets in diabetes, and its ligand capsaicin can be a promising compound for blood-glucose control. Our goal is to elucidate the effect of intraperitoneal (i.

Assessment of routine procedure effect on breathing parameters in mice by using whole-body plethysmography.

We used whole-body plethysmography to investigate the effect of restraint, ear marking, tail vein and retroorbital blood sampling, and tail clipping on respiration in Balb/c × TCR-HA +/- F1 hybrid mice (F1h). Baseline values of breathing parameters were determined. During the experiment, mice experienced a procedure and then plethysmographic recordings were obtained immediately and at 4, 24, and 48 h afterward.

Antibody and splenocyte proliferation response to whole inactivated Streptococcus pneumoniae serotype 1, 3 and 6B in mice.

Animal models of infection and protection on the topic of the Streptococcus pneumoniae (S. pneumoniae) have encountered many difficulties generated by low immunogenicity, a characteristic of polysaccharide capsular bacteria and difference of virulence between serotypes and strains. We have explored the immune response after immunization with heat inactivated S.

Evaluation of the efficacy of a specific hyperimmune serum in experimental influenza infection in mice.

Serotherapy still remains a way of treatment in some diseases, and it could be consider superior to any other mode of action because the protecting substances of the body are the products of the organism itself. The aim of the study was to establish an "in vivo" method for testing the efficacy of therapeutic serum. Hyperimmune serum for influenza A/PR8/34 viral strain, was prepared in sheep, and tested for inhibition of haemagglutination and microneutralisation.
