The cDNA encoding the precursor form of non-specific lipid-transfer protein (pre-nsL-TP) from rat liver was cloned into the expression vector pET3d. The resulting plasmid was transformed to the Escherichia coli strain BL21(DE3). After induction of the bacteria with isopropyl-beta-D-thiogalactopyranoside (IPTG) pre-nsL-TP was purified from the bacterial lysate by anion exchange chromatography fo...

The occurrence of tyrosine phosphorylation (TP) in the sperm head during capacitation has been poorly investigated, and no data exist on the relationship of its dynamics with the acquisition of sperm fertilizing ability. This study localized TP of head proteins in human spermatozoa during capacitation and explored its relationship with acquisition of the ability to display progesterone (P)-stim...

Sepsis is a major cause of acute renal failure (ARF) and death. Thromboxane A2 (TxA(2)) may mediate decreases of renal blood flow (RBF) and/or GFR associated with LPS-induced sepsis. This study tested whether TxA(2) receptor blockade, with the use of TxA(2) receptor knockout (TP-KO) mice or a selective TP receptor antagonist (SQ29,548), would alleviate LPS-induced renal vasoconstriction and ARF...

BACKGROUND AND PURPOSE Thromboxane A2 (TXA2) receptors (TP) interact with the ligand TXA2 to induce platelet aggregation and regulate hemostasis. Recently TP-mediated signaling has been suggested to function in multiple cell types in the brain. In this report, we aim to study the expression and physiological role of TP in microglia, in particular after brain ischemia. METHODS Ischemic brain s...

BACKGROUND AND OBJECTIVE Clinical trials on docetaxel plus cisplatin (DDP) (TP regimen) in treating nasopharyngeal carcinoma (NPC) are still uncertain due to limited samples. This study was to compare the short-term efficacy and toxicity of induction chemotherapy with TP regimen followed by concurrent chemoradiotherapy with TP regimen versus DDP in treating locally advanced NPC. METHODS Fifty...

We report a new class of thiophene (TP) compounds that kill Mycobacterium tuberculosis by the previously uncharacterized mechanism of Pks13 inhibition. An F79S mutation near the catalytic Ser55 site in Pks13 conferred TP resistance in M. tuberculosis. Overexpression of wild-type Pks13 resulted in TP resistance, and overexpression of the Pks13(F79S) mutant conferred high resistance. In vitro, TP...

The nonspecific lipid-transfer protein (nsL-TP) from bovine liver was studied by measuring the binding and transfer of the fluorescent phospholipid 1-palmitoyl-2-[6-(1-pyrenyl)-hexanoyl]-sn-glycero-3-phosphocholine (PamPryGroPCho). A kinetic model is presented involving three steps: (a) interaction of nsL-TP with a membrane surface; (b) equilibration of PamPyrGroPCho monomers between the membra...

Nutrient inputs from rivers play an important role in lake eutrophication. To compare the forms characteristics of phosphorus (P) and nitrogen (N) in rivers flowing through rural and urban areas, water samples were collected seasonally from five urban rivers and six rural rivers flowing to Lake Chaohu, China. Higher total phosphorus (TP), particulate phosphorus (PP), soluble reactive phosphorus...

BACKGROUND AND OBJECTIVE Successful talc pleurodesis (TP) for malignant pleural effusion (MPE) gives symptom relief, but may be too exhaustive in cases with poor performance status. The selection of eligible patients is therefore a challenging task. The study was undertaken to evaluate frequency of successful TPs, side effects, complications, performance status, hospitalization time, remaining ...
