Incidence and risk factors regarding atherosclerotic cardiovascular disease in middle-aged and elderly people with HIV treated in Chongqing, China.

Background: Atherosclerotic cardiovascular disease (ASCVD) has become an increasingly common cause of death among people living with HIV (PLHIV) receiving successful antiretroviral therapy (ART). In Chongqing, approximately half of the PLHIV were middle-aged or elderly, and their diets were mainly high in salt, spices and oil; however, there is still a lack of relevant research on the risk factors and whether the disease burden of ASCVD is greater in these areas. This study was to investigate the risk of ASCVD in middle-aged and elderly PLHIV receiving ART and analyze the factors influencing high risk.

Amphotericin B Colloidal Dispersion is Efficacious and Safe for the Management of Talaromycosis in HIV-Infected Patients: Results of a Retrospective Cohort Study in China.

Background: Amphotericin B deoxycholate (AmB-D) have potential toxic effects in the treatment of talaromycosis, and high-quality, non-generic liposomal AmB (L-AMB) is still inaccessible in many regions of China. As such, the efficacy and safety of alternative drugs warrant further investigation for the management of talaromycosis. This study aimed to compare the efficacy and safety of Amphotericin B Colloidal Dispersion (ABCD) and AmB-D for the treatment of talaromycosis in a retrospective cohort of HIV-infected patients.

Intracerebral inoculation of healthy non-transgenic rats with a single aliquot of oligomeric amyloid-β (1-42) profoundly and progressively alters brain function throughout life.

One of the puzzling aspects of sporadic Alzheimer's disease (AD) is how it commences. Changes in one key brain peptide, amyloid-beta (Aβ), accompany disease progression, but whether this comprises a trigger or a consequence of AD is still a topic of debate. It is clear however that the cerebral presence of oligomeric Aβ (1-42) is a key factor in early AD-pathogenesis.

FC-TFS-CGRU: A Temporal-Frequency-Spatial Electroencephalography Emotion Recognition Model Based on Functional Connectivity and a Convolutional Gated Recurrent Unit Hybrid Architecture.

The gated recurrent unit (GRU) network can effectively capture temporal information for 1D signals, such as electroencephalography and event-related brain potential, and it has been widely used in the field of EEG emotion recognition. However, multi-domain features, including the spatial, frequency, and temporal features of EEG signals, contribute to emotion recognition, while GRUs show some limitations in capturing frequency-spatial features. Thus, we proposed a hybrid architecture of convolutional neural networks and GRUs (CGRU) to effectively capture the complementary temporal features and spatial-frequency features hidden in signal channels.

The aim of this study was to investigate the prevalence of and risk factors for MetS and to further understand the degree of damage to target organs.

Hybrid multi-strategy chaos somersault foraging chimp optimization algorithm research.

To address the problems of slow convergence speed and low accuracy of the chimp optimization algorithm (ChOA), and to prevent falling into the local optimum, a chaos somersault foraging ChOA (CSFChOA) is proposed. First, the cat chaotic sequence is introduced to generate the initial solutions, and then opposition-based learning is used to select better solutions to form the initial population, which can ensure the diversity of the algorithm at the beginning and improve the convergence speed and optimum searching accuracy. Considering that the algorithm is likely to fall into local optimum in the final stage, by taking the optimal solution as the pivot, chimps with better adaptation at the mirror image position replace chimps from the original population using the somersault foraging strategy, which can increase the population diversity and expand the search scope.

Acute intracerebral treatment with amyloid-beta (1-42) alters the profile of neuronal oscillations that accompany LTP induction and results in impaired LTP in freely behaving rats.

Accumulation of amyloid plaques comprises one of the major hallmarks of Alzheimer's disease (AD). In rodents, acute treatment with amyloid-beta (Aβ; 1-42) elicits immediate debilitating effects on hippocampal long-term potentiation (LTP). Whereas LTP contributes to synaptic information storage, information is transferred across neurons by means of neuronal oscillations.
