Sequence Notes: Characterization of Two Novel HIV-1 Unique Recombinant Forms (CRF01_AE/B) in Hebei Province.

Many new circulating recombinant forms (CRFs) and unique recombinant forms (URFs) of human immunodeficiency virus type-1 (HIV-1) have been discovered in populations with multiple circulating HIV-1 genotypes. In this study, we report two novel URFs derived from two HIV-1-positive individuals in Hebei, China, who were infected through homosexual (BDD142) and heterosexual (BDD154) contact. Phylogenetic and recombinant analyses of the two NFLG revealed that they are second-generation recombinant strains originating from the CRF01_AE cluster 4/B and CRF01_AE cluster 5/B strains.

Underwater Superoleophobic and Transparent Films with Mechanical Robustness and High Durability in Harsh Environments.

Underwater superoleophobic and transparent (UST) films are promising in applications, such as advanced optical devices in marine environments. However, the mechanical robustness and durability in harsh environments of the existing UST films are still unsatisfactory. In this work, we present a free-standing nacre-inspired mineralized UST (NIM-UST) film with high aragonite content and excellent mechanical properties toward robust underwater superoleophobicity on two surfaces and transparency (94%) in harsh seawater environments.

An improved FLARE system for recording and manipulating neuronal activity.

Recording and manipulating neuronal ensembles that underlie cognition and behavior is challenging. FLARE is a light- and calcium-gated transcriptional reporting system for labeling activated neurons on the order of minutes. However, FLARE is limited by its sensitivity to prolonged neuronal activities.

Adaptive changes in balance control strategies under continuous exposure to visual-somatosensory conflicts.

Human postural control system has the capacity to adapt to balance-challenging perturbations. However, the characteristics and mechanisms of postural adaptation to continuous perturbation under the sensory conflicting environments remain unclear. We aimed to investigate the functional role of oscillatory coupling drive to lower-limb muscles with changes in balance control during postural adaptation under multisensory congruent and incongruent environments.

An efficient in vivo feeding method for poultry red mites, Dermanyssus gallinae (Acari: Dermanyssidae).

Dermanyssus gallinae (D. gallinae), the poultry red mite (PRM), is a haematophagous pest infesting poultry and wild birds. In studies of the biology of D.
