The photogeneration of X2 is the key to achieving an efficient HX-splitting photocycle, as it more thermodynamically and kinetically challenging than its H2 half reaction counterpart. Here we report a strategy that enables Cl2 photoelimination from low-valent binuclear d9–d9 d9–d10 Ni complexes. We demonstrate importance metal–metal bond interaction for M–X photoactivation with combination TD-D...

Let H be an ample line bundle on a non-singular projective surface X , and M(H) the coarse moduli scheme of rank-two H-semistable sheaves with fixed Chern classes on X . We show that if H changes and passes through walls to get closer to KX , then M(H) undergoes natural flips with respect to canonical divisors. When X is minimal and κ(X) ≥ 1, this sequence of flips terminates in M(HX); HX is an...

Data regularization is cast as a least-squares inversion problem. The model space is a five-dimensional (t,cmpx, cmpy, hx, hy) hypercube. The regularization minimizes the difference between various (t, cmpx, cmpy) cubes by applying a filter that acts in (hx,hy) plane. Azimuth Move-out is used transform the cubes to the same ( hx,hy) before applying the filter. The methodology is made efficient ...

The in vitro susceptibility of varicella zoster (VZ) isolates to adenine arabinoside (ara-A) and hypoxanthine arabinoside (ara-Hx) was determined in human skin fibroblasts. Using a system in which deamination was inhibited, and using a modified plaque reduction method, the antiviral activities of ara-A and ara-Hx were separated. The plaque inhibitory concentration of ara-A for all VZ isolates t...

The aim of this study was to investigate the interaction between long-chain fatty acids (LCFA) and growth hormone (GH) in the regulation of liver fatty acid binding protein (LFABP) and peroxisome proliferator-activated receptor-alpha (PPARalpha). Cultured rat hepatocytes were given oleic acid (OA; 500 microM) and GH (100 ng/ml) for 3 days. LFABP mRNA increased 3.6-fold by GH and 5.7-fold by OA,...

One of the most important molecules mediating the proliferation, growth, and metastasis of cancer cells is insulin-like growth factor (IGF), with its receptor IGF-1R. Here, we describe the potential of an IGF-1R monoclonal antibody, HX-1162, on liver cancer apoptosis in vitro and in vivo. We found that HX-1162 could induce the apoptosis of cultured liver cancer cells. Additionally, HX-1162 trea...

Transcription of hemopexin (Hx) occurs predominantly in the liver. To investigate the contribution of the cis-acting enhancer element to the hepatocyte preferential expression, we performed chloramphenicol acetyl-transferase (CAT) assays in HepG2 cells. A strong enhancer element was identified by successive truncation to reside in the region -157/-104 from the cap site. The Hx region -145/-125 ...

Hereditary xerocytosis (HX) is a rare disorder caused by defects of RBC permeability, associated with haemolytic anaemia of variable degree and iron overload. It is sometimes misdiagnosed as hereditary spherocytosis or other congenital haemolytic anaemia. Splenectomy is contraindicated due to increased risk of thromboembolic complications. We report the clinical, haematological, and molecular c...

Adhesion of human colon carcinoma variant cell lines expressing different levels of the cell surface sialyl Lewis X (sLe) antigen to frozen sections of mouse liver was examined. KM12-HX cells that bound the monoclonal antibody (mAb) FH6 (anti-sLe) and thus expressed a high level of sLe demonstrated a greater degree of adhesion to liver sections than their low-binding counterparts, KM12-LX cells...
