BACKGROUND: Nucleos(t)ide analogs (NUCs) are the standard of care for chronic hepatitis B (CHB). The present analysis aimed to determine the cost effectiveness of NUCs in Chinese healthcare settings. METHODS: A Markov model was used to simulate two therapeutic strategies for a hypothetical patient cohort diagnosed with hepatitis B e antigen-positive CHB, unwilling or unable to receive interferon therapy, and about to start treatment with any NUC. The first strategy included NUC monotherapy without sequencing (telbivudine [LDT], entecavir [ETV], tenofovir [TDF], lamivudine [LAM], adefovir dipivoxil [ADV], and combination therapies of either LDT and ADV or LDT and TDF, followed by best supportive care [BSC])...

Persistent hepatitis B virus (HBV) infections affect about 240 million patients worldwide that are at risk of developing liver cirrhosis or hepatocellular carcinoma. HBV is a small, partially double stranded DNA virus with four overlapping genes and a unique life cycle, which involves the generation of an RNA template for replication via reverse transcription. Mutations occur frequently during chronic infection, and particular selection pressures select distinct mutants. Nucleoside and nucleotide analogues like lamivudine (LMV), entecavir (ETV), telbivudine (LdT), adefovir dipivoxil (ADV) and tenofovir (TDF) are used to achieve long-term suppression of viral replication...

A growing body of evidence demonstrates that quinoline compounds have attracted much attention in the field of drug development. Accordingly, 4-phenylselenyl-7-chloroquinoline (4-PSQ) is a new quinoline derivative containing selenium, which showed a potential antioxidant, antinociceptive and anti-inflammatory effect. The present study was undertaken to evaluate the anxiolytic-like properties of 4-PSQ. Mice were orally pretreated with 4-PSQ (5-50 mg/kg) or vehicle, 30 min prior to the elevated plus-maze (EPM), light-dark (LDT) or open field (OFT) tests...

Coordinated activity in different sets of widely-projecting neurochemical systems characterize waking (W) and sleep (S). How and when this coordination is achieved during development is not known. We used embryos and newborns of a precocial bird species (chickens) to assess developmental activation in different neurochemical systems using cFos expression, which has been extensively employed to examine cellular activation during S and W in adult mammals. Similarly to adult mammals, newborn awake chicks showed significantly higher cFos expression in W-active hypocretin/orexin (H/O), serotonergic Dorsal Raphe, noradrenergic Locus Coeruleus and cholinergic Laterodorsal and Pedunculopontine Tegmental (Ch-LDT/PT) neurons when compared to sleeping chicks...

The number of orthographic neighbors of a word influences its probability of being retrieved in recognition and free recall memory tests. Even though this phenomenon is well demonstrated for English words, it has yet to be demonstrated for languages with more predictable grapheme-phoneme mappings than English. To address this issue, 4 experiments were conducted to investigate effects of number of orthographic neighbors (N) and effects of frequency of occurrence of orthographic neighbors (NF) on memory retrieval of Brazilian Portuguese words...

Subcortical functions for language capacities are poorly defined, but may be investigated in the context of deep brain stimulation. Here, we studied event-related potentials recorded from electrodes in the subthalamic nucleus (STN) and the thalamic ventral intermediate nucleus (VIM) together with surface-EEG. Participants completed a lexical decision task (LDT), which required the differentiation of acoustically presented words from pseudo-words by button press. Target stimuli were preceded by prime-words. In recordings from VIM, a slow potential shift apparent at the lower electrode contacts persisted during target stimulus presentation (equally for words and pseudo-words)...

The laterodorsal tegmental nucleus (LDT), which sends cholinergic efferent connections to dopaminergic (DA) neurons in the ventral tegmental area (VTA), plays a critical role in the development of addictive behavior and the reinstatement of cocaine-seeking behavior. Although repeated cocaine exposure elicits plastic changes in excitatory synaptic transmission and intrinsic membrane excitability in LDT cholinergic neurons, it remains unclear whether inhibitory synaptic transmission is modulated by cocaine exposure...

Previous studies indicated that reduced androgen levels may contribute to both physical and cognitive disorders in men, including Alzheimer's disease. New drug candidates for Alzheimer's disease in patients with androgen deficiency should ideally be able to act not only on multiple brain targets but also to correct impaired endocrine functions in hypogonadal men with Alzheimer's disease. Ropren(®) is one such candidate for the treatment of Alzheimer's disease in men with an imbalance of androgens. Accordingly, the aim of the current study was to examine the effects of long-term Ropren(®) administration (8...

BACKGROUND: Nucleos(t)ide analogues are widely used to treat chronic hepatitis B virus infection, but drug resistance is common. The role of hepatitis B virus surface gene variants in drug resistance to nucleos(t)ide analogues is unknown. We are trying to investigate the dynamics of S gene mutations and how they relate to a patient's virologic response in this study. METHODS: Thirty patients with chronic hepatitis B were enrolled and serum samples were collected at multiple time-points during treatment with telbivudine (LdT)...

Previous research has examined the effects of emotional experience (i.e., the ease with which words evoke emotion information) in semantic categorization (SCT), word naming, and Stroop tasks (Newcombe et al., 2012; Siakaluk et al., 2014; Moffat et al., 2015). However, to date there are no published reports on whether emotional experience influences performance in the lexical decision task (LDT). In the present study, we examined the influence of emotional experience in LDT using three different stimulus sets...

We address the impact of the spin-orbit (SO) coupling on the localization-delocalization-transition (LDT) in a spin-orbit coupled Bose-Einstein condensate in a bichromatic potential. We find that SO coupling significantly alters the threshold depth of the one of sublattices above which the lowest eigenstates transform from delocalizated into localized. For some moderate coupling strengths the threshold is strongly reduced, which is explained by the SO coupling-induced band flattening in one of the sub-lattices...

The scope of FDA's jurisdiction over laboratory-developed tests (LDTs), and whether FDA has such jurisdiction at all, has been a heavily debated issue over the past several years. If FDA moves forward with its guidance, or Congress takes action to reform LDT and IVD regulation, a fundamental question that needs to be answered is how to divide activities regulated by FDCA from those regulated by CLIA. In this article, we consider FDA's authority to regulate LDTs and the policy implications of regulation, and discuss an idea for a fact-driven framework to distinguish FDCA- and CLIA- activities...

BACKGROUND: Chronic tinnitus affects 5 % of the population, 17 % suffer under the condition. This distress seems mainly to be dependent on negative cognitive-emotional evaluation of the tinnitus and selective attention to the tinnitus. A well-established paradigm to examine selective attention and emotional processing is the Emotional Stroop Task (EST). Recent models of tinnitus distress propose limbic, frontal and parietal regions to be more active in highly distressed tinnitus patients...

INTRODUCTION: Latissimus dorsi tendon transfer (LDT) is a recent method for surgical treatment of massive, irreparable posterosuperior cuff tears (MIPCT). So far, there are no studies on the quantitative motion analysis of the shoulder and latissimus dorsi (LD) muscle activation after LDT. The changes in shoulder movements after LDT can be objectively assessed by the 3-D motion analysis. These changes may not be due to an increased activity of the LD muscle as external rotator. MATERIALS AND METHODS: The shoulder kinematics of nine patients with MIPCT were recorded through a 3-D motion analysis system, before LTD (T0), and after 3 (T1) and 6 (T2) months post-LDT...

BACKGROUND: The value of liver-directed therapy (LDT) in patients with metastasic renal cell carcinoma (MRCC) is still an active field of research, particularly in the era of tyrosinkinase inhibitor (TKI) therapy. METHODS: The records of 35 patients with MRCC undergoing LDT of metastasic liver lesions between 1992 and 2015 were retrospectively analyzed. Immediate postoperative TKI was given in a subgroup of patients after LDT for metastasic lesions. Uni- and multivariate models were applied to assess overall survival (OS), progression-free survival (PFS) and disease-free survival (DFS)...
