Amyloid-β (Aβ) accumulation, accelerated by traumatic brain injury (TBI), may play a crucial role in neurodegeneration in chronic-stage TBI. The injury type could influence Aβ dynamics because of TBI's complex, heterogeneous nature. We, therefore, investigated spatial patterns of amyloid deposition according to injury type after TBI using 5-(5-(2-(2-(2-[F]-fluoroethoxy)ethoxy)ethoxy)benzofuran-2-yl)-
-methylpyridin-2-amine (
F-FPYBF-2) positron emission tomography (PET).

Altogether, 20 patients with chronic TBI [12 with focal injury, 8 with diffuse axonal injury (DAI)] underwent
F-FPYBF-2 PET, structural magnetic resonance imaging (MRI), and neuropsychological examination. Additionally, 50 healthy controls underwent either
F-FPYBF-2 PET (n=30) or structural MRI (n=20).

Standardized uptake value ratio (SUVR) on PET images and regional brain volumes were measured in four cortical (frontal, parietal, occipital, temporal) and subcortical (combined caudate, putamen, pallidum, thalamus) regions. Patients with DAI showed significantly increased (compared with controls) SUVR in occipital and temporal cortices and decreased brain volume in occipital cortex (corrected p < 0.05). Although patients with focal injury showed decreased SUVR in all regions except occipital cortex, there were no significant differences (compared with controls) in the SUVR in any regions. There were no significant correlations between increased SUVR and neuropsychological impairments in patients with DAI.

Varying spatial patterns of amyloid deposition suggest amyloid pathology diversity depending on the injury type in chronic-TBI patients.

It has neuroprogressive course and a high rate of treatment resistance. Hence, there is an unquestionable need for new BD treatment strategies. Ketamine appears to have rapid antidepressive and antisuicidal effects. Since most of the available studies concern unipolar depression, here we present a novel insight arguing that ketamine might be a promising treatment for bipolar disorder.
Compliance and maintenance of abstinence is a major issue in substance use disorders. Adverse effects of opioid maintenance treatments (OMT) include sexual dysfunctions. #link# There is a vast amount of studies regarding sexual adverse effects of conventional OMTs; however, information regarding buprenorphine/naloxone (Bup/Nal) combination is limited, mostly evaluated in western populations and controversial. In this study, we aimed to assess the sexual adversities of Bup/Nal treatment in a Turkish alcohol and substance use disorder treatment center sample.

We recruited 100 subjects continuing sublingual Bup/Nal combination and 35 control subjects. Subjects were evaluated via the the Golombok-Rust Inventory of Sexual Satisfaction (GRISS) for sexual dysfunction and for erectile dysfunction (ED) with the International Index of Erectile Function-5 (IIEF-5) as a comparison.

The mean dose of our treatment was 9.05. Overall sexual dysfunction scores were not significantly different in between groups with GRISS. ED ataying in the treatment.
Antibiotic resistance issues associated with microbial pathogenesis are considered to be one of the most serious current threats to health. Fortunately, TiO
, a photoactive semiconductor, was proven to have antibacterial activity and is being widely utilized. However, its use is limited to the short range of absorption wavelength.

In this work, heterostructured TiO
-FeS
nanocomposites (NCs) were successfully prepared by a facile solution approach to enhance light-induced antibacterial activity over a broader absorption range.

In TiO
-FeS
NCs, FeS
NPs, as light harvesters, can effectively increase light absorption from the visible (Vis) to near-infrared (NIR). Results of light-induced antibacterial activities indicated that TiO
-FeS
NCs had better antibacterial activity than that of only TiO
nanoparticles (NPs) or only FeS
NPs. Reactive oxygen species (ROS) measurements also showed that TiO
-FeS
NCs produced the highest relative ROS levels. Unlike TiO
NPs, TiO
-FeS
NCs, under light irradiation with a 515-nm filter, could absorb light wavelengths longer than 515 nm to generate ROS. In the mechanistic study, we found that TiO
NPs in TiO
-FeS
NCs could absorb ultraviolet (UV) light to generate photoinduced electrons and holes for ROS generation, including ⋅O

and ⋅OH; FeS
NPs efficiently harvested Vis to NIR light to generate photoinduced electrons, which then were transferred to TiO
NPs to facilitate ROS generation.

TiO
-FeS
NCs with superior light-induced antibacterial activity could be a promising antibacterial agent against bacterial infections.

Agomelatine (AGM) is the first melatonergic antidepressant. It suffers from low oral bioavailability (<5%) due to extensive hepatic metabolism. The current work aimed to develop an alternative AGM-loaded invasomes to enhance transdermal drug bioavailability.

AGM-loaded invasomes were developed using two drug lipid ratios (110 or 17.5), four terpene types (limonene, cineole, fenchone or citral) and two terpene concentrations (0.75% or 1.5%, w/v). They were characterized for drug entrapment efficiency (EE%), particle size (PS), zeta potential (ZP) and drug released percentages after 0.5h (Q
) and 8h (Q
). The optimum invasomes (I1, I2 and I4) were evaluated for morphology, drug-crystallinity, and ex-vivo drug flux. The variables influencing sonophoresis of the best achieved invasomal gel system (I2) were optimized including, ultrasound frequency (low, LFU or high, HFU), mode (pulsed or continuous), application period (10 min or 15 min) and duty cycle (50% or 100%). AGM pharmacokinetics were evaluated in rabbits following transdermal application of I2-LFU-C4 system, relative to AGM oral dispersion.

The superiority of I2 invasomes [comprising AGM and phosphatidylcholine (110) and limonene (1.5% w/v)] was statistically revealed with respect to EE% (78.6%), PS (313 nm), ZP (-64 mV), Q
(30.1%), Q
(92%), flux (10.79 µg/cm2/h) and enhancement ratio (4.83). The optimum sonophoresis conditions involved application of LFU in the continuous mode for 15 min at a 100% duty cycle (I2-LFU-C4 system). The latter system showed significantly higher C
, and relative bioavailability (≈ 7.25 folds) and a similar T
(0.5 h).

I2-LFU-C4 is a promising transdermal system for AGM.

Vascular endothelial growth factor receptor 2 (VEGFR-2) and neuropilin-1 (NRP-1) are two prominent synergistic receptors overexpressed on new blood vessels in glioma and may be promising targets for antiglioma therapy. The aim of this study was to design a dual receptor targeting and blood-brain barrier (BBB) penetrating peptide-modified polyethyleneimine (PEI) nanocomplex that can efficiently deliver the angiogenesis-inhibiting secretory endostatin gene (pVAXI-En) to treat glioma.

We first constructed the tandem peptide TAT-AT7 by conjugating AT7 to TAT and evaluated its binding affinity to VEGFR-2 and NRP-1, vasculature-targeting ability and BBB crossing capacity. Then, TAT-AT7-modified PEI polymer (PPTA) was synthesized, and a pVAXI-En-loaded PPTA nanocomplex (PPTA/pVAXI-En) was prepared. The physicochemical properties, cytotoxicity, transfection efficiency, capacities to cross the BBB and BTB (blood-tumor barrier) and glioma-targeting properties of PPTA/pVAXI-En were investigated. Moreover, the in viv gene delivery system for effective glioma therapy.
Our study demonstrates that PPTA/pVAXI-En can be exploited as an efficient dual-targeting nanocomplex to cross the BBB and BTB, and hence it represents a feasible and promising nonviral gene delivery system for effective glioma therapy.
Asthma-COPD overlap (ACO) has been reported as an association with a lower quality of life, frequent exacerbations, and higher mortality than those with COPD alone. However, clinical characteristics and outcomes of ACO remain controversial.

We conducted a prospective observational study analyzing data of patients with stable COPD enrolled from the Ishinomaki COPD Network Registry. Patients with features of asthma who had a history of respiratory symptoms that vary over time and intensity, together with documented variable expiratory airflow limitation, were identified, and then defined as having ACO. The characteristics, frequency of exacerbations, and mortality during the 3-year follow-up were compared between patients with ACO and patients with COPD alone.

Among 387 patients with COPD, 41 (10.6%) were identified as having ACO. link2 Patients with ACO tended to be younger, have higher BMI, have a shorter smoking history, and use more respiratory medications, especially inhaled corticosteroids. Inflammatory biomarkers including fractional exhaled nitric oxide, blood eosinophil count, total immunoglobulin E (IgE) level, and presence of antigen-specific IgE were significantly higher in patients with ACO than in those with COPD alone. Lung function, mMRC score, CAT score, and comorbidity index were not different between the groups. Tolinapant clinical trial of all exacerbations and severe exacerbations required hospital admission were not different between ACO and COPD alone (0.20 vs 0.14, 0.12 vs 0.10, events per person, respectively). link3 Mortality was significantly higher in patients with COPD alone compared with those with ACO during the study period (P=0.037).

The results of our study indicate that ACO is not associated with poor clinical features nor outcomes in an outpatient COPD cohort receiving appropriate treatment.

The forced mid-expiratory flow (FEF
) value is a potentially sensitive marker of obstructive peripheral airflow. We aimed to assess whether FEF
can be an early predictor of chronic obstructive pulmonary disease (COPD).

Between July 1, 2007 and June 31, 2009, we identified 3624 patients who underwent a pulmonary function test (PFT) in Gangnam Severance Hospital. We selected 307 patients aged over 40 years without COPD who had normal PFT results at baseline and who had follow-up PFT records more than 1 year later. A FEF
z-score less than-0.8435was considered low. We defined COPD as a forced expiratory volume in one second/forced vital capacity value of less than 0.7 before July 31, 2019.

Among 307 patients, 91 (29.6%) had lowFEF
at baseline. After 10 years, the incidence rate of COPD in the low FEF
group was significantly higher than that in the normal FEF
group (41.8% vs 7.4%;
<0.001). The Cox proportional hazard model showed that age (hazard ratio [HR]1.09;
-value<0.001), smoking status (occasional smoker HR, 4.59;
-value<0.001and long-term smoker HR, 2.18;
-value=0.023), and lowFEF
(HR, 3.31;
-value<0.001) were predictive factors for the development of COPD.

The FEF
value in patients with normal lung function is a useful predictor for the development of COPD. We should carefully monitor patients who present with low FEF
values, even if they have normal lung function.
The FEF25-75% value in patients with normal lung function is a useful predictor for the development of COPD. We should carefully monitor patients who present with low FEF25-75% values, even if they have normal lung function.
