Prefrontal cortex (PFC) is involved in multiple functions including attentional , spatial orientation, short and long-term memory. Our previous study indicated that microinjection of testosterone in CA1 impaired spatial learning and memory. Some evidence suggests that impairment effect of testosterone is mediated by GABAergic system. In the present study, we investigated the interaction of test...

Phellinus linteus (PL) mushroom possesses anti-tumor property. We previously reported that the treatment with PL caused cultured human prostate cancer cells to undergo apoptosis. To further studying the mechanisms of PL-mediated apoptosis, we performed xenograft assay, together with in vitro assays, to evaluate the effect of PL on the genesis and progression of the tumors formed from the inocul...

Pancreatic exocrine insufficiency (PEI) is a disease of diverse aetiology-e.g., majority of patients suffering from cystic fibrosis (CF) show PEI congenitally. Malnutrition and malabsorption of nutrients impair growth and nutritional status. As reduced fat digestion leads to a deficiency of fat-soluble vitamins the supplementation is standard, but absorption is a critical point in PEI-patients....

Photoluminescence (PL) in GaN or InGaN layers monitored during epitaxial growth at high temperatures permits a quasi-continuous in situ characterization of opto-electronic properties. Therefore, epitaxial parameters can now be optimized at the earliest possible stage. A pulsed and high-power UV laser was required for PL excitation at high temperatures. Herein, the underlying nonlinear mechanism...

The phospholipid (PL) requirement in fish is revealed by enhanced performance when larvae are provided PL-enriched diets. To elucidate the molecular mechanism underlying PL requirement in Atlantic salmon, Salmo salar, were fed a minimal PL diet and tissue samples from major lipid metabolic sites were dissected from fry and parr. In silico analysis and cloning techniques demonstrated that salmon...

Plasma lipid and lipoprotein profile was determined in 12 cirrhotics, 15 patients with cirrhosis and hepatocellular carcinoma (HCC) and 20 healthy volunteers. When compared with controls plasma total cholesterol (TC), high density lipoprotein cholesterol (HDLC), high density lipoprotein phospholipids (HDLPL), HDLPL/PL levels were low, phospholipid (PL) was normal and HDLC/TC and PL/TC were high...

Force transmission between rat ankle plantar-flexors has been found for physiological muscle lengths and relative positions, but only with all muscles maximally activated. The aims of this study were to assess intermuscular mechanical interactions between ankle plantar-flexors during (i) fully passive conditions, (ii) excitation of soleus (SO), (iii) excitation of lateral gastrocnemius (LG), an...

Thymosin proteins are well known for their actin-binding activity. Thymosin beta 4 (Tβ4) has been associated with biological activities in tissue repair and cell migration via interaction with ATP-synthase in vertebrates, while the information of similar thymosin functions in invertebrates is limited. We have shown previously that ATP-synthase is present on the surface of crayfish hematopoietic...

We have studied the magnetic field 50 T dependence of the photoluminescence PL of self-assembled InAs /GaAs quantum dots as a function of temperature T . As the temperature is raised from 4.2 up to 80 K, thermal redistribution causes the PL to be increasingly dominated by dots with a lower PL energy. Magneto-PL demonstrates that these low-energy dots are larger in size only in the growth direct...

BACKGROUND Standard protocols are lacking for the preparation of platelet lysates (PL) as an alternative to using fetal bovine serum as a cell culture supplement. This study aimed to establish optimum conditions for preparing PL for use in cell cultures. METHODS Cell density in three pooled platelet concentrates (PC) were adjusted to 1×10(12)/L and 2×10(12)/L. PL was prepared from PC by 1 to ...
