nocardiosis has been reported increasingly in recent two decades, probably due to improvement in isolation of the organism and increased burden of immune compromised patients. nocardia occasionally has been reported in healthy people. a case series of definitive nocardiosis (2002 to 2010), clinical characteristics, underlying diseases, immune status and in-patient outcome were studied in a tert...

The immune status of an individual is made up of the absolute number (cells/μl) and relative ratios of each category of immune cells. To determine the extent of similarity of the immune status between individuals across malignancies, we described the immune status using quantitative whole blood flow cytometry of ten immune markers and generated immune phenotypes from 40 healthy volunteers and 1...

Neutrophils are part of the first line of immune response and are essential for resistance against a variety of pathogens. They professionally mediate direct killing of pathogens, recruit other phagocytes by specific chemokines, produce cytokines and interact with different immune cells to shape the adaptive response. Leishmania as an obligatory intracellular parasite has evolved to benefit thi...

The immune system provides vital protection against pathogens, but extensive evidence suggests that mounting immune responses can entail survival and fecundity costs. The physiological mechanisms that underpin these costs remain poorly understood, despite their potentially important role in shaping life-histories. Recent studies involving laboratory models highlight the possibility that oxidati...

Background: Invasive ductal carcinoma is the most common type of breast cancer in Iran. Impaired immune responses occur frequently in cancer patients, but the mechanisms of the induced immune defects remain poorly understood. It is believed that infiltrated immune cells, especially macrophages, may provide help for tumor cell growth and metastasis.   Objective: To analyze the status of tumor as...

Background and Objectives: Chicken pox has potential complications during pregnancy for both the mother and her baby. The aim of this study was to determine the Varicella-zoster virus (VZV) immune status in pregnant women in Babol and its surrounding neighborhoods. Materials and Methods: This seroepidemiological study was carried out on 427 pregnant women referred to Rohani Hospital, Babol, no...

Background: It has been reported previously that dietary fiber intake provides health benefits. Nevertheless, only a limited number of human studies have investigated whether gender differences exist in the relationship between fiber intake and perceived health and immune status. Objective: To investigate potential gender differences in the effects of dietary fiber intake on perceived health an...

Objective(s): To investigate the systemic and local immune status of two surgical rat models of sciatic nerve injury, a crushed sciatic nerve, and a sciatic nerve transection Materials and Methods:Twenty-four adult male Sprague-Dawley rats were randomly divided into three groups: sham-operation (control group), sciatic nerve crush, and sciatic nerve transaction. Sciatic nerve surgery was perfor...

BACKGROUND Mental resilience can be seen as a trait that enables an individual to recover from stress and to face the next stressor with optimism. People with resilient traits are considered to have a better mental and physical health. However, there are limited data available assessing the relationship between resilient individuals and their perspective of their health and immune status. There...
