A photoresponsive micellar solution is developed as a promising working fluid for district heating/cooling systems (DHCs). It can be reversibly switched between a drag reduction (DR) mode and an efficient heat transfer (EHT) mode by light irradiation. The DR mode is advantageous during fluid transport, and the EHT mode is favored when the fluid passes through heat exchangers. This smart fluid i...

Small nucleolar RNAs (designated as snoRNAs in Eukarya or sRNAs in Archaea) can be grouped into H/ACA or C/D box snoRNA (sRNA) subclasses. In Eukarya, H/ACA snoRNAs assemble into a ribonucleoprotein (RNP) complex comprising four proteins: Cbf5p, Gar1p, Nop10p and Nhp2p. A homolog for the Nhp2p protein has not been identified within archaeal H/ACA RNPs thus far, while potential orthologs have be...

OBJECTIVE To assess the occurrence of anticardiolipin antibodies (ACA) (as well as of anti-DNA antibodies) in patients with rheumatoid arthritis treated with etanercept or combination therapy. METHODS Eight patients treated with etanercept 25 mg twice weekly were studied for a period of 85 weeks. A control group of 39 patients with rheumatoid arthritis undergoing combination treatment (methot...

Infarction in the anterior cerebral artery (ACA) territory is an uncommon cause of stroke. The clinical findings of ACA infarctions are not fully characterized but include contralateral hemiparesis, urinary incontinence, transcortical aphasia, agraphia, apraxia, and executive dysfunction. We report a patient with a large right ACA infarction, who in addition to previously reported findings also...

BACKGROUND Cervical cancer is the fourth most frequent malignancy affecting women worldwide, but drug resistance and toxicities remain a major challenge in chemotherapy. The use of natural compounds is promising because they are less toxic and able to target multiple signaling pathways. The 1'S-1'-acetoxychavicol acetate (ACA), a natural compound isolated from wild ginger Alpinia conchigera, in...

Background: Apart from genetic and environmental factors, activation of autoreactive mechanisms has been proposed to play a role in the pathogenesis of schizophrenia. In re-cent years, considerable work has been carried out to understand the role and contribution of the immune system in this disease. Objective: To investigate the T cell response to phytohaemagglutinin (PHA) and determine the se...

Background Incidence of anomalous coronary anatomy (ACA) in caucasian and middle eastern patients with ventricular septal defect (VSD) and pulmonary stenosis (PS) is between 29%. Prevalence of ACA in South Asian (SA) patients is unknown. Patients with VSD and PS may have Tetrology of Fallot (TOF) or Double Outlet Right ventricle (DORV) morphology. This study looks at the prevalence of ACA in SA...

The crystallographic structure of the plasminogen kringle 4-epsilon-aminocaproic acid (ACA) complex (K4-ACA) has been solved by molecular replacement rotation-translation methods utilizing the refined apo-K4 structure as a search model (Mulichak et al., 1991), and it has been refined to an R value of 0.148 at 2.25-A resolution. The K4-ACA structure consists of two interkringle residues, the kri...

This work studies some aspects of the computational power of fully asynchronous cellular automata (ACA). We deal with some notions of simulation between ACA and Turing Machines. In particular, we characterize the updating sequences specifying which are “universal”, i.e., allowing a (specific family of) ACA to simulate any TM on any input. We also consider the computational cost of such simulati...

We investigated the activation of transient receptor potential cation channel (TRP) subfamily V, member 1 (TRPV1) and TRP subfamily A, member 1 (TRPA1) by 1'-acetoxychavicol acetate (ACA), the main pungent component in galangal. ACA did not activate TRPV1-expressing human embryonic kidney (HEK) cells, but strongly activated TRPA1-expressing HEK cells. ACA was more potent than allyl isothiocyana...
