35 Previously, we introduced a monkey model for human frontal midline 36 theta oscillations, as a possible neural correlate of attention. It was based on 37 homologous theta oscillations found in the monkey's prefrontal and anterior 38 cingulate cortices (areas 9 and 32) in a self-initiated hand-movement task. 39 However, it has not been confirmed whether theta activity in the monkey 40 model c...
for development of pollinator parent resistant to powdery mildew disease of sugar beet, relatively resistant 14442 population was used. based on resistance index, 50 resisitant plants were selected to produce half sib family(h.s.f). after random pollination between these 50 plants, seed of h.s.f was harvesed. from these 50 plants, only 39 plants had produced enough seed. next year these h.s.f w...
where on the left hand side the coefficient of XrY s is βrβs. If n is a natural number then β(X) = β([n]X), where [n]X = [n]F X is the n-series. We alse have β(X)−1 = β([−1]X), where F ([−1]X,X) = 0 = F (X, [−1]X). In fact, for any non-zero q ∈ Z(p), we can make sense of [q]X and β(X) = β([q]X). Now recall the Araki and Hazewinkel generators vn, wn ∈ BP2pn−2 for which v0 = w0 = p and vn ≡ wn mo...
گیاهان علوفه ای با تامین غذای دام، جایگاه ویژه ای در تولید پروتئین مورد نیاز انسان دارند. از جمله گیاهان علوفه ای که در ایران می تواند در جبران کمبود علوفه نقشی مهم داشته باشد، گیاه اسپرس است. ایران از مراکز تنوع اسپرس محسوب می شود و دارای ذخایر ژنتیکی ارزشمندی از این گیاه است. در بیشتر منابع علمی قابل دسترس اسپرس گیاهی دگرگشن معرفی شده ولی میزان و نحوه انجام دگرگشنی کاملا مشخص نمی باشد. شناخت ...
The thiol-specific photoactivatable reagent benzophenone-4-iodoacetamide can be incorporated into myosin subfragment 1 (S1), accompanied by an increase of Ca2+-ATPase and the loss of K+-ATPase activities, a characteristic property of S1 when reactive sulfhydryl 1 (SH-1) is modified. After trypsin cleavage, 25-kDa, 50-kDa, and 20-kDa fragments were found upon NaDodSO4/polyacrylamide gel electrop...
بردتلا پرتوسیس باکتری گرم منفی و عامل بیماری سیاه سرفه در دستگاه تنفسی انسان است . پرتوسیس توکسین مهمترین آنتی ژن این باکتری در ایجاد پاتوژنیسیته و ایجاد محافظت بوده و زیر واحد s1 مهمترین زیرواحد این توکسین است. در این مطالعه برای بیان مهمترین زیر واحد پرتوسیس توکسین، پس از تکثیر ژن s1، وکتور های بیانی paed4 pet- 22b(+), pet-28a, pet-14b, حاوی ژن s1 به باکتری اشرشیا کلی (de3) bl21 و (plys s) b...
Cellular and Humoral Immunogenicity of a Candidate DNA Vaccine Expressing SARS-CoV-2 Spike Subunit 1
The urgent need for effective, safe and equitably accessible vaccines to tackle the ongoing spread of COVID-19 led researchers generate vaccine candidates targeting varieties immunogens SARS-CoV-2. Because its crucial role in mediating binding entry host cell proven safety profile, subunit 1 (S1) spike protein represents an attractive immunogen development. Here, we developed assessed immunogen...
STUDY DESIGN A prospective comparative study. PURPOSE To describe the changes in the spinopelvic parameters on normal Koreans more than 50 years of age. OVERVIEW OF LITERATURE There are differing opinions regarding the changes in the thoracic kyphosis, lumbar lordosis, C7 plumb with age in the elderly population. METHODS Sagittal standing radiographs of the whole spine including the pelvi...
Corticofugal influences on the responses of ventrobasal (VB) thalamic neurons to repetitive stimuli were studied in anesthetized rats by suppressing primary somatosensory (S1) electrocortical activity with topically applied lidocaine. Effective concentrations of lidocaine were confined to S1 and immediately adjacent cortex and suppressed evoked S1 responses and corticofugal discharges. Suppress...
