No-till (NT) cropping systems have the potential to enhance soil aggregation, providing physical protection and C sequestration. The existence of discrepancies in impact tillage on aggregation sequestration warrants further studies, particularly for different crop rotations. We hypothesized following: a) NT biannual rotations tend be more effective restoring large macroaggregation concentration...

Elevating spinal levels of neurotrophin NT-3 (NT3) while increasing expression of the NR2D subunit of the NMDA receptor using a HSV viral construct promotes formation of novel multisynaptic projections from lateral white matter (LWM) axons to motoneurons in neonates. However, this treatment is ineffective after postnatal day 10. Because chondroitinase ABC (ChABC) treatment restores plasticity i...

The following experiments compared the efficiency of three fusion/activation protocols following somatic cell nuclear transfer (SCNT) with porcine somatic cells transfected with enhanced green fluorescent protein driven by the chicken beta-actin/rabbit beta-globin hybrid promoter (pCAGG-EGFP). The three protocols included electrical fusion/activation (NT1), electrical fusion/activation followed...

Nghiên cứu được thực hiện trên 9 đàn gà nòi Bến Tre (tên khoa học) giai đoạn 1 - 13 tuần tuổi nuôi theo mô hình bán chăn thả ở nông hộ tỉnh Tre. Các chia thành 3 nhóm quy tương ứng với nghiệm thức (NT1: 1.000-1.200 con, NT2: 1.200-1.500 NT3: 1.500-1.800 con). Kết quả nghiên cho thấy sự khác biệt có ý nghĩa thống kê (P<0,05) giữa về khối lượng từ tuổi, tăng lượng, hệ số chuyển hóa ăn và tỉ lệ...

Objective(s): The stimulation of neural stem cells (NSCs) differentiation into neurons has attracted great attention in management of neurodegenerative disease and traumatic brain injury. It has been reported that selegiline could enhance the morphologic differentiation of embryonic stem cells. Therefore this study aimed to investigate the effects of selegiline on NSCs differentiation with focu...

Neurotrophic factors control a range of activities in developing neurons, including survival, proliferation, migration and neuronal differentiation. Two classes of neurotrophic factors that are strongly linked to neuronal development of the peripheral nervous system are the neurotrophins and GDNF family ligands. Like other trophic factors they act by triggering signalling through receptor tyros...

AIMS Members of the growth factor family of neurotrophins [NTs; e.g. brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT3)] and their high-affinity receptors (tropomyosin-related kinase; Trk) and low-affinity receptors p75 neurotrophin receptor (p75NTR) have been localized to pulmonary artery (PA) in humans. However, their role is unclear. Based on previous findings of NTs and their re...

OBJECTIVE Royal College of Surgeons (RCS) rats develop vasculopathy as photoreceptors degenerate. The aim of this study was to examine the effect of erythropoietin (EPO) on retinopathy in RCS rats. METHODS Fluorescein angiography was used to monitor retinal vascular changes over time. Changes in retinal glia and vasculature were studied by immunostaining. To study the effects of EPO on retina...
