Natural killer (NK) cells have the potential to be effective killers of tumor cells. They are governed by inhibitory and activating receptors such as NKG2D, whose ligands are normally upregulated in cells that are stressed, like cancer cells. Advanced cancer cells, however, have ways to reduce the expression of these ligands, leaving them less detectable by NK cells. Along with these receptors, NK cells also require activating cytokines, such as IL-12. A previous study in our laboratory showed that a fusion protein of the extracellular domain of mouse UL-16 binding protein-like transcript 1 (MULT1E) and mouse interleukin 12 (IL-12) can effectively activate mouse NK cells by in vitro assays and in vivo in animal tumor models...

Haemonchus contortus is one of the most significant strongylid nematodes infecting small ruminants and causes great economic losses to the livestock industry worldwide. Accurate diagnosis of H. contortus is crucial to control the infection. Traditional microscopic examinations are the most common methods for the diagnosis of H. contortus, but they are time-consuming and inaccurate. Molecular methods based on PCR are more accurate, but need expensive machines usually only used in the laboratory. Loop-mediated isothermal amplification (LAMP) is a rapid, simple, specific and sensitive method that has been widely used to detect viruses, bacteria and parasites...

BACKGROUND AND OBJECTIVES: Epidemiological studies consistently find that Asian populations report lower rates of alcohol use disorders (AUD) compared with other racial groups. These differences result from a variety of biological, genetic, and environmental influences, some of which are related to the metabolism of alcohol. We will review several studies of these metabolic factors, including several alcohol clamping studies conducted in our laboratory, that provide further insight into the role of the alcohol metabolizing genes and drinking behavior among Japanese drinkers...

Although actuarial data indicate that risk-taking behavior peaks in adolescence, laboratory evidence for this developmental spike remains scarce. One possible explanation for this incongruity is that in the real world adolescents often have only vague information about the potential consequences of their behavior and the likelihoods of those consequences, whereas in the lab these are often clearly stated. How do adolescents behave under such more realistic conditions of ambiguity and uncertainty? We asked 105 participants aged from 8 to 22 years to make three types of choices: (1) choices between options whose possible outcomes and probabilities were fully described (choices under risk); (2) choices between options whose possible outcomes were described but whose probability information was incomplete (choices under ambiguity), and (3) choices between unknown options whose possible outcomes and probabilities could be explored (choices under uncertainty)...

Since its introduction into Europe the invasive Drosophila suzukii has established and spread widely, thereby entering habitats populated by native Drosophila species and their natural enemies. The highly prolific D. suzukii will likely interact with these species as a competitor, host or prey. To investigate potential interactions of D. suzukii with parasitoids, a field survey was conducted across several fruit-growing regions in Switzerland in two consecutive years. Eight species of hymenopteran parasitoids were collected using D...

Although not mandatory for patients, many Muslims fast in Ramadan. We aimed to investigate the effects of long hours (17.5) fasting on renal functions in patients with chronic kidney disease (CKD). Stage 3-5 CKD patients with stable renal function were recruited to this prospective observational study three months ahead of Ramadan in 2015. All patients were instructed regarding possible deleterious effects of dehydration caused by fasting. Forty-five patients (mean age 66.8 ± 10.3 years, 68.8% male) chose to fast and 49 (mean, age: 64...

Chronic kidney disease is defined as progressive kidney dysfunction. The levels of various cytokines increase in hemodialysis (HD) patients. High levels of interleukins (ILs) and presence of metabolic acidosis are described as independent risk factors for morbidity and mortality in these patients. This study was designed to evaluate the relationship between IL-6 and IL-10 and serum bicarbonate and metabolic acidosis in HD patients. In this analytical crosssectional study, patients referred to the HD units of Loghman Hakim and Shahid Ashrafi Esfahani Hospitals were randomly selected...

BACKGROUND: With nephrotic syndrome, cortisol levels may be falsely lowered by loss of cortisol-binding globulin (CBG) in the urine. An incorrect diagnosis of adrenal insufficiency could therefore be made. CASE DESCRIPTION: We describe the case of a 52-year-old female with nephrotic syndrome that did not sufficiently respond to medication. Treatment management was complicated by symptomatic hypotension, which was thought to be caused by adrenal insufficiency. The cortisol levels in the blood were low and a clinical cause could not be identified...

Melanogenesis is a process to synthesize melanin, which is a primary responsible for the pigmentation of human skin, eye and hair. Although numerous enzymatic catalyzed and chemical reactions are involved in melanogenesis process, the enzymes such as tyrosinase and tyrosinase-related protein-1 (TRP-1) and TRP-2 played a major role in melanin synthesis. Specifically, tyrosinase is a key enzyme, which catalyzes a rate-limiting step of the melanin synthesis, and the downregulation of tyrosinase is the most prominent approach for the development of melanogenesis inhibitors...

Glycated hemoglobin (HbA1c) measurement from whole blood (WB) samples is inconvenient for epidemic surveillance and self-monitoring of glycemic level. We evaluated HbA1c measurement from WB blotted on filter paper (FP), which can be easily transported to central laboratories, with high-performance liquid chromatography (HPLC) and immunoturbidimetric assay (ITA). WB was applied to Whatman filter paper. By using HPLC and WB samples as reference methods, these FP samples were evaluated on HPLC and ITA. Inter- and intra-assay variation, WB vs...
