Lung adenocarcinoma (LUAD) remains the most prevalent and lethal subtype of lung cancer, largely due to late diagnosis and therapeutic resistance. In this study, we conducted a comprehensive multi-omics analysis to characterize the pleckstrin homology domain-containing (PLEKHA) family gene in LUAD. Among the eight members, PLEKHA6 was uniquely overexpressed in LUAD tissues and significantly associated with poor prognosis.

Lung adenocarcinoma (LUAD) remains to be one of the most prevalent and highly invasive forms of cancer. Mitochondrial outer membrane protein-2 or Metaxin-2 (MTX2), a key regulator of mitochondrial function, has been linked to cellular bioenergetics and stress response mechanisms. However, its roles in the progression and prognosis of LUAD remain largely unexplored.

Anterior cervical discectomy and fusion (ACDF) is a standard procedure for degenerative diseases of the cervical spine, providing nerve decompression and spinal stabilization. However, it limits cervical spine motility, restricts fused segment activity, and may lead to adjacent degeneration. Cervical disc arthroplasty (CDA) is an accepted alternative that preserves the structure and flexibility of the cervical spine.

"Theory of mind" (ToM) refers to the ability to predict others' thoughts, intentions, beliefs, and feelings. Evidence from neuropsychology and functional imaging indicates that ToM is a domain-specific or modular architecture; however, research in development psychology has suggested that ToM is the full development of the executive functions in individuals. Therefore, the relationship between ToM and the executive functions needs to be clarified.

Introduction: Mentalizing ability is the issue in the social cognition of patients with brain injury that has received the most attention. The present study investigated mentalization ability in patients with prefrontal cortex damage. The aims of this study were to investigate: (a) whether patients with prefrontal cortex damage are impaired in mentalizing ability, including theory of mind (ToM) and empathy; (b) whether patients with ventromedial prefrontal cortex damage are impaired in different aspects of ToM; (c) whether patients with ventromedial prefrontal cortex damage are impaired in different aspects of empathy; and (d) whether impairment of mentalizing ability in patients with prefrontal cortex damage can be explained by executive dysfunction.

The role of ionic currents on procaine-elicited action potential bursts was studied in an identifiable RP1 neuron of the African snail, Achatina fulica Ferussac, using the two-electrode voltage clamp method. The RP1 neuron generated spontaneous action potentials and bath application of procaine at 10 mM reversibly elicited action potential bursts in a concentration-dependent manner. Voltage clamp studies revealed that procaine at 10 mM decreased [1] the Ca2+ current, [2] the Na+ current, [3] the delayed rectifying K+ current I(KD), and [4] the fast-inactivating K+ current (I(A)).

Background: L-dopa has been used for Parkinson's disease management for a long time. However, its wide variety in the rate and the extent of absorption remained challenge in designing suitable therapeutic regime. We report here a design of using D-phenylglycine to guard L-dopa for better absorption in the intestine via intestinal peptide transporter I (PepT1).

This study sought to determine the effects of (+) methamphetamine (METH) and its ring-substituted analog (+/-)3,4-methylenedioxymethamphetamine (MDMA; ecstasy) on electrophysiological behavior and their relationships to second messenger systems in an identifiable RP4 neuron of the African snail, Achatina fulica Ferussac. Extracellular application of MDMA at 1mM and METH at 3mM elicited action potential bursts that were not blocked after immersing the neurons in Ca(2+)-free solution. Notably, MDMA- (1mM) elicited action potential bursts were blocked by pretreatment with the protein kinase C (PKC) inhibitors chelerythrine (20 microM) and Ro 31-8220 (20 microM), but not by the PKA inhibitors KT-5720 (10 microM) and H89 (10 microM).

Effects of sodium azide (NaN(3)) on spontaneously generated action potential and bursts of potential elicited by d-amphetamine (d-amphetamine-elicited BoP) were studied on the right parietal 4 (RP4) neuron of the snail Achatina fulica Ferussac in vitro. Sodium azide altered the spontaneous action potential of RP4 neuron in a concentration-dependent manner. In lower concentrations, neither NaN(3) (30, 100, 300 microM; 1 and 3 mM) nor d-amphetamine (135 microM) affect the resting membrane potential, amplitude and frequency of RP4 neurons, while in the higher concentrations NaN(3) (30 mM) did abolish the spontaneous action potential on RP4 neurons and depolarized the RP4 neurons reversibly.

Isolates of Newcastle disease virus (NDV) from chicken cases were obtained from various locations in Taiwan during 2003-2006 and were genotypically analyzed by using reverse transcription polymerase chain reaction (RT-PCR) with primers specific to the viral fusion (F) protein gene (534 bp). Part of the amplified F protein DNA product (nucleotide sequence 47-418) and the deduced amino acid sequences were compared phylogenetically with those from strains previously reported in Taiwan and other geographic regions. Our results showed that all Taiwanese isolates (n=20) collected during 2003-2006, according to the phylogenetic tree, belong to the genotype VIId.
