Given two symplectic manifolds (M1, ω1), (M2, ω2) a Lagrangian correspondence is a Lagrangian submanifold L ⊂ (M1 ×M2,−ω1 ⊕ ω2). These are the central objects of the theory of holomorphic quilts as developed by Wehrheim and Woodward in [21]. Consider two Lagrangian correspondences Li ⊂ (Mi−1 ×Mi,−ωi−1 ⊕ ωi) for i = 1, 2. Let ∆ = {(x, y, z, t) ∈ M0 ×M1 ×M1 ×M2 | y = z} If L1 × L2 is transverse t...
Tumor-associated macrophages (TAMs) represent an important cellular subset within the glioblastoma (WHO grade IV) microenvironment and are a potential therapeutic target. TAMs display a continuum of different polarization states between antitumorigenic M1 and protumorigenic M2 phenotypes, with a lower M1/M2 ratio correlating with worse prognosis. Here, we investigated the effect of macrophage p...
Leukocyte 8-hydroxy-2'-deoxyguanosine (8-OHdG) is a surrogate marker of oxidant-induced DNA damage in patients undergoing maintenance hemodialysis (MHD). Glutathione S-transferase M1 (GST M1) is a member of the GST family of proteins, which protect cellular DNA against oxidative damage. This study tested the association of a common GST M1 gene polymorphism [GST M1(-)], known to produce a dysfun...
Several subtypes of melanopsin-expressing, intrinsically photosensitive retinal ganglion cells (ipRGCs) have been reported. The M1 type of ipRGCs exhibit distinct properties compared with the remaining (non-M1) cells. They differ not only in their soma size and dendritic arbor, but also in their physiological properties, projection patterns, and functions. However, it is not known how these dif...
Background & Aims: Aflatoxin M1 is one of the most important toxins present in milk and the product of aflatoxin B1 metabolism in liver microsomes. The aim of this project was to study the aflatoxin M1 adsorption ability of polystyrene-hydroxyapatite nanocomposite. Methods: First, the probability of aflatoxin M1 adsorption by the nanocomposite was evaluated us...
Background and purpose: Aflatoxin M1 is a toxic compound that is placed in class IIB (carcinogenic) by the WHO- International Agency for Research on Cancer, so its monitoring in milk is a great public health issue. The purpose of this study was to determine the concentration of aflatoxin M1 in raw, pasteurized milk and samples of milk produced for school milk project in Shahrood, Iran. Mate...
Traumatic brain injury (TBI) is physical damage to the brain structure which has a high global rate of mortality and morbidity. TBI can cause intense inflammatory response due to accumulation of leukocytes in cerebral matrix and activation of microglia. Microglia can differentiate into M1 macrophages or M2 macrophages following the changes in biochemical properties of brain tissue. M1 sub type ...
آفلاتوکسین به‌عنوان یکی از قویترین مواد سرطان‌زا تهدید جدی برای سلامت جامعه محسوب می‌شود و برنامه‌ریزی برای کاهش میزان آفلاتوکسین M1 در شیر و فراورده‌های آن بدون ارزیابی وضعیت موجود امکان‌پذیر نیست. در این بررسی میزان آفلاتوکسین در شیرهای پاستوریزه شهر تبریز اندازه‌گیری شد. 74 نمونه شیر پاستوریزه تولیدی یازده کارخانه مختلف در فصول پاییز و زمستان 93 جمع‌آوری شد. مقدار آفلاتوکسین M1 با روش الایز...
وراثت مقاومت سفیدبالک گلخانه، Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae)، به دو ترکیب ایمیداکلوپرید و کلرپایریفوس مورد مطالعه قرار گرفت. در این پژوهش، از جمعیت فیلستان ورامین (FL) عنوان والد مقاوم فردیس کرج (FR) حساس استفاده شد. مقدار ترتیب حدودا 62/13 91/14 برابر بود. عدم وجود اختلاف معنی‌دار LC50 روی تلاقی‌های F1 (R♂×S♀) Fʹ1 (R♀×S♂) نشان داد که T. نوع اتوزومی (غیرجنسی) است. ه...
Propriospinal premotoneurons (PN) are essential for accurate control of the upper limb. They receive bilateral input from premotor (PM) and primary motor (M1) cortices. In humans, excitability of PNs can be estimated from motor-evoked potentials (MEPs) by pairing a descending volley using transcranial magnetic stimulation (TMS) to summate with an ascending volley from peripheral nerve stimulati...
