Cystic fibrosis (CF) is the most common autosomal recessive disease in the Caucasian population, but it has also been widely diagnosed in the Mexican population. Production of viscous secretions affects the secretory epithelia and the respiratory condition usually leads to death. The relationship between the CFTR genotype and the disease phenotype is not well understood. Other risk factors such as genetic and autoimmune influence the development of this disease. We analyzed the PTPN22 R620W polymorphism (+1858 C/T, rs2476601) in 78 DNA samples from CF patients and 232 healthy controls from northeast Mexico using the polymerase chain reaction-restriction fragment length (PCR-RFLP) method...

Mammalian target of rapamycin (mTOR) inhibitors are strong anti-tumor drugs; however, they have adverse immunosuppressive side effects in some cancer patients. Animal studies have provided evidence that mTOR inhibitors improved tumor-specific T-cells adoptive transfer in which the quality of CD8+ T-cells is a major factor for predicting success. Interestingly, mTOR inhibitors are capable of stimulating cytotoxic CD8+ T-cell if their dose/duration is adjusted. Rapamycin-induced CD8+ T-cells have also been associated with tumor immunity in animal models...

BACKGROUND AND AIMS: Older adults with type 2 diabetes mellitus (DM2) exhibit accelerated decline in some domains of cognition including verbal episodic memory. Few studies have investigated the influence of DM2 status in older adults on recognition memory for more complex stimuli such as faces. In the present study we sought to compare recognition memory performance for words, objects and faces under conditions of relatively low and high cognitive load. METHODS: Healthy older adults with good glucoregulatory control (n = 13) and older adults with DM2 (n = 24) were administered recognition memory tasks in which stimuli (faces, objects and words) were presented under conditions of either i) low (stimulus presented without a background pattern) or ii) high (stimulus presented against a background pattern) cognitive load...

BACKGROUND AND AIMS: Bacteremia is a common serious manifestation of disease in the intensive care unit (ICU), which requires quick and accurate determinations of pathogens to select the appropriate antibiotic treatment. To overcome the shortcomings of traditional bacterial culture (BC), we have adapted next-generation sequencing (NGS) technology to identify pathogens from cell-free plasma DNA. METHODS: In this study, 78 plasma samples from ICU patients were analyzed by both NGS and BC methods and verified by PCR amplification/Sanger sequencing and ten plasma samples from healthy volunteers were analyzed by NGS as negative controls to define or calibrate the threshold of the NGS methodology...

BACKGROUND AND AIMS: Activation of telomerase reverse transcriptase (hTERT) has a role in liver carcinogenesis where telomerase is normally suppressed in most human somatic tissues after birth. In the current study we aimed to detect the significance of hTERT mRNA in early detection of hepatocellular carcinoma (HCC) and to determine the relationship between serum microRNA155 and telomerase expression. METHODS: Serum and liver tissue samples were collected from 40 patients (17 samples from patients with liver cirrhosis and 23 samples from patients with HCC) and 12 blood samples from healthy subjects were collected...
