Using extracorporeal membrane oxygenation in donations after cardiac death or brain death: A single-center experience and long-term outcome.

Aims: The use of extended criteria donors is a routine practice that sometimes involves extracorporeal membrane oxygenation (ECMO) in donations after cardiac death or brain death.

Efficient DNA-Driven Nanocavities for Approaching Quasi-Deterministic Strong Coupling to a Few Fluorophores.

Strong coupling between light and matter is the foundation of promising quantum photonic devices such as deterministic single photon sources, single atom lasers, and photonic quantum gates, which consist of an atom and a photonic cavity. Unlike atom-based systems, a strong coupling unit based on an emitter-plasmonic nanocavity system has the potential to bring these devices to the microchip scale at ambient conditions. However, efficiently and precisely positioning a single or a few emitters into a plasmonic nanocavity is challenging.

Evaluation of Clinical Neuropathy After Living Donor Liver Transplant.

Objectives: Neurologic complications are more common in liver transplants than in other solid-organ transplants. One such neurologic complication, peripheral neuropathy, may cause functional limitations for recipients and have a negative effect on posttransplant quality of life. We aimed to examine the risk factors associated with the occurrence of clinical neuropathy after liver transplant and to investigate the frequency of sensory deficits.

Railway crossing risk area detection using linear regression and terrain drop compensation techniques.

Most railway accidents happen at railway crossings. Therefore, how to detect humans or objects present in the risk area of a railway crossing and thus prevent accidents are important tasks. In this paper, three strategies are used to detect the risk area of a railway crossing: (1) we use a terrain drop compensation (TDC) technique to solve the problem of the concavity of railway crossings; (2) we use a linear regression technique to predict the position and length of an object from image processing; (3) we have developed a novel strategy called calculating local maximum Y-coordinate object points (CLMYOP) to obtain the ground points of the object.

Tamsulosin versus terazosin for benign prostatic hyperplasia: a systematic review.

The effectiveness and safety of tamsulosin and terazosin for patients with benign prostatic hyperplasia (BPH) was evaluated by literature review. PubMed, Embase, the Cochrane Library, Chinese biomedicine literature database (CBM), reference lists of reports, and reviews were searched for randomized controlled trials (RCTs), or quasi-RCTs of tamsulosin versus terazosin in BPH. Twelve studies involving 2,816 men were included.

Development of a novel ligand that activates JAK2/STAT5 signaling through a heterodimer of prolactin receptor and growth hormone receptor.

The objective of this study was to determine if a functional heterodimer of prolactin receptor (PRLR) and growth hormone receptor (GHR) can be formed in humans. A novel ligand was designed that is composed of a GHR antagonist (B2036) and a PRLR antagonist (G129R) fused in tandem (B2036-G129R). Because both B2036 and G129R are binding site 2 inactive antagonists, the B2036-G129R fusion protein, in theory contains only two functional binding site 1s: one for GHR and one for PRLR.

Dinuclear iron(II)-cyanocarbonyl complexes linked by two/three bridging ethylthiolates: relevance to the active site of [Fe] hydrogenases.

Dinuclear iron(II)-cyanocarbonyl complex [PPN](2)[Fe(CN)(2)(CO)(2)(mu-SEt)](2) (1) was prepared by the reaction of [PPN][FeBr(CN)(2)(CO)(3)] and [Na][SEt] in THF at ambient temperature. Reaction of complex 1 with [PPN][SEt] produced the triply thiolate-bridged dinuclear Fe(II) complex [PPN][(CN)(CO)(2)Fe(mu-SEt)(3)Fe(CO)(2)(CN)] (2) with the torsion angle of two CN(-) groups (C(5)N(2) and C(3)N(1)) being 126.9 degrees.

Assay of Adenylyl Cyclase Activity by Ion-exchange High-performance Liquid Chromatography.

Adenylyl cyclase(AC)activity was determined by directly quantifying the product cAMP with ion-exchange HPLC. When AC reaction was terminated, the reaction mixture was kept at 0 degrees for 2 h to remove residual ATP utilizing the action of ATP-hydrolyzing enzymes existed in the crude AC preparation of membrane pellet. Papaverine was removed by the dichloromethane extraction, and cAMP was quantified by chromatography on a WAX-1 HPLC column with baseline-resolution.

A novel design of targeted endocrine and cytokine therapy for breast cancer.

The aim of this study is to combine endocrine therapy [human prolactin (hPRL) antagonist, G129R] and immune therapy [interleukin 2 (IL2)] in the design of a fusion protein, G129R-IL2, to treat human breast cancer. This novel approach uses the specific interaction between the G129R and hPRL receptors (PRLRs), thus directly targeting the fusion protein to the malignant breast tissues that have previously been shown to contain high levels of PRLR. The localized bifunctional fusion protein is designed to block signal transduction induced by hPRL as well as to activate T lymphocytes near the tumor site.

Six-coordinate and five-coordinate Fe(II)(CN)(2)(CO)(x) thiolate complexes (x = 1, 2): synthetic advances for iron sites of [NiFe] hydrogenases.

The dicyanodicarbonyliron(II) thiolate complexes trans,cis-[(CN)(2)(CO)(2)Fe(S,S-C-R)](-) (R = OEt (2), N(Et)(2) (3)) were prepared by the reaction of [Na][S-C(S)-R] and [Fe(CN)(2)(CO)(3)(Br)](-) (1). Complex 1 was obtained from oxidative addition of cyanogen bromide to [Fe(CN)(CO)(4)](-). In a similar fashion, reaction of complex 1 with [Na][S,O-C(5)H(4)N], and [Na][S,N-C(5)H(4)] produced the six-coordinate trans,cis-[(CN)(2)(CO)(2)Fe(S,O-C(5)H(4)N)](-) (6) and trans,cis-[(CN)(2)(CO)(2)Fe(S,N-C(5)H(4))](-) (7) individually.
