Toward a universal influenza virus vaccine: Some cytokines may fulfill the request.

The influenza virus annually causes widespread damages to the health and economy of the global community. Vaccination is currently the most crucial strategy in reducing the number of patients. Genetic variations, the high diversity of pandemic viruses, and zoonoses make it challenging to select suitable strains for annual vaccine production.

Challenging TaqMan probe-based real-time PCR and loop-mediated isothermal amplification (LAMP): the two sensitive molecular techniques for the detection of toxoplasmosis, a potentially dangerous opportunistic infection in immunocompromised patients.

Due to defects and drawbacks of most conventional diagnostic methods including serology for the diagnosis of toxoplasmosis as a dangerous opportunistic infection in immunocompromised individuals, the accurate, rapid, and sensitive detection of infection in such patients is essential. In this study, the TaqMan probe-based real-time PCR and, a relatively new nucleic acid amplification method, the loop-mediated isothermal amplification (LAMP) technique was compared based on the repetitive elements (RE) sequence to detect Toxoplasma gondii (T. gondii) DNA in blood samples of immunocompromised individuals.

Aptasensors as a new sensing technology developed for the detection of MUC1 mucin: A review.

Mucin 1 protein (MUC1) is a membrane-associated glycoprotein overexpressed in the majority of human malignancies and considered as a predominant protein biomarker in cancers. Owing to the crucial role of MUC1 in cancer dissemination and metastasis, detection and quantification of this biomarker is of great importance in clinical diagnostics. Today, there exist a wide variety of strategies for the determination of various types of disease biomarkers, especially MUC1.

The Effect of Estrogen Replacement Therapy on Visceral Fat, Serum Glucose, Lipid Profiles and Apelin Level in Ovariectomized Rats.

Objectives: Ovarian hormones have been shown to regulate body weight, intra-abdominal fat accumulation and plasma level of cytokines. The aim of this study was to investigate the effect of estrogen replacement therapy on visceral adipose tissue, plasma level of apelin, lipid profiles, and glucose in ovariectomized (OVX) rats.

Methods: Thirty female Wistar rats were divided into OVX (n = 20) and sham (n = 10) groups.

Vitamin D is associated with metabotropic but not neurotrophic effects of exercise in ovariectomized rats.

Purpose: Here, we studied the beneficial effects of aerobic exercise on metabolic syndrome components, cognitive performance, brain derived neurotrophic factor (BDNF) and irisin in ovariectomized rats with different serum vitamin D (Vit D) status.

Methods: Eighty female wistar rats were divided into 2 groups of sham operated (sham, n = 8), and ovariectomized (OVX, n = 72). Then OVX were divided into 9 groups of receiving combination of exercise protocol with low dose of Vit D (OVX + EXE + LD), high dose of Vit D (OVX + EXE + HD), Vit D deficiency (OVX + EXE - D), and (OVX + EXE + Veh).

Effect of exercise training on saliva brain derived neurotrophic factor, catalase and vitamin c.

The balance between production of Reactive Oxygen Species (ROS) and antioxidant defense in the body has important health implications. The aim of this study was to investigate the changes in salivary antioxidants: catalase, vitamin C and brain-derived neurotrophic factor (BDNF), in sedentary men at rest and after acute exhaustive exercise. This randomized controlled clinical trial (The registry code IRCT2011053212431N1) recruited twenty-five sedentary men (age=21±3yrs; height=172±8cm; weight=66±9kg; VO2 max=37.

Generation and characterization of nanobodies targeting PSMA for molecular imaging of prostate cancer.

Nanobodies show attractive characteristics for tumor targeting in cancer diagnosis and therapy. A radiolabeled nanobody binding the prostate-specific membrane antigen (PSMA) could offer a noninvasive strategy to select prostate cancer patients eligible for PSMA-targeted therapies. We here describe the generation, production and in vivo evaluation of anti-PSMA nanobodies.

Influence of aerobic training and detraining on serum BDNF, insulin resistance, and metabolic risk factors in middle-aged men diagnosed with metabolic syndrome.

Objective: To study the influence of aerobic exercise training on brain-derived neurotrophic factor (BDNF), insulin resistance, and lipid profile in middle-aged men diagnosed with metabolic syndrome (MetS).

Design: This is an experimental repeated measure study.

Setting: Subjects participated in aerobic training programs (18 sessions of 25-40 minutes per session) in Guilan University gymnasium and court.

Long term habitual exercise is associated with lower resting level of serum BDNF.

This experiment has been designed to evaluate the basal serum BDNF level and memory performance, and also the change in BDNF in response to acute aerobic and anaerobic training in athletes and sedentary groups. Nineteen middle aged elite athletes (45-65 years) who used to be competing at domestic championship for more than 10 years and 20 sedentary subjects participated in this study. Blood samples and cognitive function were assessed at rest and also after performing a single bout of acute aerobic and anaerobic exercise.

Camel heavy chain antibodies against prostate-specific membrane antigen.

Prostate-specific membrane antigen (PSMA), a type II integral membrane glycoprotein, is highly overexpressed in all forms of prostate cancer tissues. It has also been demonstrated in a wide range of neovasculature of non-prostatic solid tumors, including bladder, pancreas, lung, kidney, colorectal, and gastric cancers. Given the unique expression of PSMA, it is considered an alluring target for antibody-based imaging and therapy of cancer.

Transplanted bone marrow mesenchymal stem cells improve memory in rat models of Alzheimer's disease.

The present study aims to evaluate the effect of bone marrow mesenchymal stem cells (MSCs) grafts on cognition deficit in chemically and age-induced Alzheimer's models of rats. In the first experiments aged animals (30 months) were tested in Morris water maze (MWM) and divided into two groups: impaired memory and unimpaired memory. Impaired groups were divided into two groups and cannulated bilaterally at the CA1 of the hippocampus for delivery of mesenchymal stem cells (500 × 10(3)/μL) and PBS (phosphate buffer saline).

Dopaminergic activity in the medial prefrontal cortex modulates fear conditioning.

The purpose of the present study was to determine the role of medial prefrontal cortex (mPFC) dopaminergic system in fear conditioning response considering individual differences. Animals were initially counterbalanced and classified based on open field test, and then were given a single infusion of the dopamine agonist, amphetamine (AMPH) and antagonist, clozapine (CLZ) into the medial prefrontal cortex. Rats received tone-shock pairing in a classical fear conditioning test and then exposed to the tone alone.
