In this work, anatase/rutile mixed phase titanium dioxide (TiO₂) particles prepared via sonochemical combined with calcination process was immobilized on borosilicate glass beads via sol-gel dip coating technique utilizing titanium tetraisopropoxide (TTIP). The optical properties of mixed phase TiO₂ was evaluated by diffuse reflectance UV-Vis spectrophotometer to confirm phase transformation of anatase to rutile phase at different calcination temperatures. Phase identification and structural properties of TiO₂ particles were analyzed using X-ray diffraction (XRD) and transmission electron microscopy (TEM). Surface morphology of mixed phase TiO₂ coated on glass beads with different coating precursor solution were monitored by scanning electron microscope. The chemical composition of coated beads was characterized by energy dispersive spectroscopy to affirm the presence of TiO₂ on glass bead substrate.

Secondary brain damageafter traumatic brain injury (TBI) involves oxidative stress, neuroinflammation, apoptosis, and necroptosis and can be reversed by understanding these molecular pathways. The objective of this study was to examine the impact of tasimelteon (Tasi) administration on brain injury through the nuclear factor erythroid 2-related factor 2 (NRF-2)/heme oxygenase-1 (HO-1) and receptor-interacting protein kinase 1 (RIPK1)/receptor-interacting protein kinase 3 (RIPK3)/mixed lineage kinase domain-like (MLKL) pathways in rats with TBI. Thirty-two male Wistar albino rats weighing 300-350 g were randomly divided into four groups: the control group, trauma group, Tasi-1 group (trauma + 1 mg/kg Tasi intraperitoneally), and Tasi-10 group (trauma + 10 mg/kg Tasi intraperitoneally).

Background: Cabotegravir + rilpivirine (CAB + RPV) administered via intramuscular gluteal injections is the first complete long-acting regimen for maintaining human immunodeficiency virus type 1 (HIV-1) virologic suppression. We present substudy results on short-term repeat intramuscular CAB + RPV long-acting thigh injections in participants with ≥3 years of experience with gluteal administration during the ATLAS-2M study.
Methods: Substudy phases included screening, thigh injection (day 1-week 16), and return to gluteal injection (week 16-week 24).

We investigate a continuous electrochemical pH-swing method to capture CO from a gas phase. The electrochemical cell consists of a single cation-exchange membrane (CEM) and a recirculation of a mixture of salt and phenazine-based redox-active molecules. In the absorption compartment, this solution is saturated by CO from a mixed gas phase at high pH.

Fear extinction is the foundation of exposure therapy for anxiety and phobias. However, the stability of extinction memory diminishes over time, coinciding with fear recovery. To augment long-term extinction retention, the temporal distribution of extinction learning sessions is critical.

The hypothesis of this study was that grass silage digestibility would influence the response of dairy cows offered diets differing in CP content. Thirty-two mid-lactation Holstein dairy cows were used in a 2-period (21-d adaption phase, 7-d measurement phase), partially balanced change-over experiment. Four treatments were organized in a 2 × 2 factorial arrangement, comprising 2 grass silages differing in digestible OM in the DM (D-value; 748 and 668 g/kg DM, high-D and low-D, respectively) and 2 total diet CP levels (target 145 and 175 g/kg DM, high CP and low CP, respectively).
