Background: Integrated proton therapy - MRI systems are capable of delivering high doses to the target tissues near sensitive organs and achieve better therapeutic results; however, the applied magnetic field for imaging, influences the protons path, changes the penetration depth and deflects the particles, laterally, leading to dose distribution variations. Objective: To determine the effects of a magnetic field on the range and the lateral deflection of protons, analytically...

Dengue fever (DF) is a mosquito-borne acute viral disease presenting with hemorrhagic manifestations in severe cases. Southeast Iran is in close proximity to Pakistan, an endemic country for DF. This cross-sectional study was conducted in the Sistan and Baluchestan province in the southeast of Iran to investigate possibility of DF (immunoglobulin M [IgM], immunoglobulin G [IgG], and nonstructural protein 1 [NS1] antigen tests) in 60 clinically suspected patients (April 2013 to August 2015). NS1 protein was detected in 5% ( N = 3), at least one of the antibodies (IgM and/ or IgG) was detected in 11% ( N = 7) of the samples...

BACKGROUND: Free radical damage is known to occur during liver regeneration. The Ginkgo biloba extract EGb761 has antioxidant properties due to its ability to scavenge free radicals. FK506 has been widely used as an immunosuppressant that stimulates hepatocyte proliferation following partial hepatectomy. AIMS: To explore whether EGb761 enhances liver regeneration after hepatectomy in rats, we investigated the effects of EGb761 alone and in combination with FK506 on the liver regenerative process...

Hermaphroditism is known as ovotesticular disorder of sex development. A 14-year-old boy was admitted with right acute scrotum. Exploration revealed tunica rupture and hematoma, with no viable tissue. After one month, he was admitted again with left hemiscrotal pain. Microscopic examination of the left gonad demonstrated foci of hemorrhagic cysts, primordial follicles, and regions of seminiferous tubules. We preserved testicular tissue and the ovarian part was extracted completely. Long-term follow-up with his hormonal profile are reported...

In this study, the influence and optimization of the factors of a non-formaldehyde resin finishing process on cotton fabric using a Taguchi-based grey relational analysis were experimentally investigated. An L27 orthogonal array was selected for five parameters and three levels by applying Taguchi's design of experiments. The Taguchi technique was coupled with a grey relational analysis to obtain a grey relational grade for evaluating multiple responses, i.e., crease recovery angle (CRA), tearing strength (TE), and whiteness index (WI)...

BACKGROUND: Caveolae play a role in cell signal transduction, kinetic regulation of transport vesicles, and cellular physiology. In this study, we evaluated the role of caveolin-1 (CAV-1) genotypes in the risk of breast cancer. PATIENTS AND METHODS: We evaluated 6 single nucleotide polymorphisms of the CAV-1 gene in a sample size of 406 participants. Six polymorphisms-G32124A (rs3807992), T29107A (rs7804372), T28608A (rs3757733), G21985A (rs12672038), G14713A (rs3807987), and C521A (rs1997623)-were assessed using restriction fragment length polymorphism polymerase chain reaction...

BACKGROUND: Vitamin K2 (VK2) belongs to the vitamin K family and comprises a number of subtypes differing in length of side chains consisting of isoprenoid groups (menaquinone-n, MK-n). It is essential for a number of physiological functions although the full spectrum of activity has not yet been elucidated. Due to its role in protection of mitochondrial damage, VK2 could be relevant in preventing disease progress in multiple sclerosis (MS). METHODS: We measured VK2 serum levels by the double antibody sandwich Enzyme-linked Immunosorbent Assay (ELISA) technique in MS patients and age and sex matched controls, both under vitamin D supplementation, and related it to disease characteristics and treatment...

There is a pressing need for a ubiquitously expressed antigen or receptor on the tumor surface for successful mitigation of the deleterious side effects of chemotherapy. Phosphatidylserine (PS), normally constrained to the intracellular surface, is exposed on the external surface of tumors and most tumorigenic cell lines. Here we report that a novel PS-targeting liposome, phosphatidylcholine-stearylamine (PC-SA), induced apoptosis and showed potent anticancer effects as a single agent against a majority of cancer cell lines...

Castleman disease (CD) is a rare lymphoproliferative disorder subclassified as unicentric CD (UCD) or multicentric CD (MCD) based on clinical features and the distribution of enlarged lymph nodes with characteristic histopathology. MCD can be further subtyped based on human herpes virus 8 (HHV8) infection into HHV8-associated MCD, HHV8- /idiopathic MCD (iMCD), and polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin change (POEMS)-associated MCD. In a subset of cases of UCD, an associated follicular dendritic cell sarcoma (FDCS) may be seen...

Embryonic stem cells (ESCs) have the ability to differentiate into several cell lineages and self-renew. Through a spontaneous process, ESCs can differentiate into germ cells of various stages, partly due to their self-renewal ability and their microenvironment culture. Human and mouse ESC differentiation into putative primordial germ cells (PGCs) has been demonstrated by several studies; in fact, derivation of functional mouse male gametes has also been reported. However, the exact underlying mechanisms are yet to be understood properly, and as such clinical applications of ESC-derived PGC remains controversial...

Altered lipid metabolism and aberrant protein translation are strongly associated with cancerous outgrowth; however, the inter-regulation of these key processes is still underexplored in diffuse large B-cell lymphoma (DLBCL). Although fatty acid synthase (FASN) activity is reported to positively correlate with PI3K-Akt-mTOR pathway that can modulate protein synthesis, the precise impact of FASN inhibition on this process is still unknown. Herein, we demonstrate that attenuating FASN expression or its activity significantly reduces eIF4B (eukaryotic initiation factor 4B) levels and consequently overall protein translation...

PURPOSE: The present study investigated group differences between the thickness changes of the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) muscles, during performance of the isometric supine chest raise and the supine double leg-straight leg raise tests in women with and without low back pain (LBP). METHOD: Twenty women with LBP and 20 women without LBP participated in this case-control study. The thickness of the right TrA, IO, and EO muscles was measured using B-mode ultrasound (US) at rest, immediately at the beginning of performing the tests and when participants in both groups self-reported fatigue...

BACKGROUND: Gaucher disease is characterized by the activation of splenic and hepatic macrophages, accompanied by dramatically increased levels of angiotensin-converting enzyme (ACE). To evaluate the source of the elevated blood ACE, we performed complete ACE phenotyping using blood, spleen and liver samples from patients with Gaucher disease and controls. METHODS: ACE phenotyping included 1) immunohistochemical staining for ACE; 2) measuring ACE activity with two substrates (HHL and ZPHL); 3) calculating the ratio of the rates of substrate hydrolysis (ZPHL/HHL ratio); 4) assessing the conformational fingerprint of ACE by evaluating the pattern of binding of monoclonal antibodies to 16 different ACE epitopes...
