Architecture of a novel NIR and switch-on fluorescent chemosensor based on mercapto propanehydrazide-functionalized chromenylium-cyanine for the quantification of mercury(II) in environment and living cells.

A novel probe NIR8 decorated with colorimetric, fluorometric, turn-on, and NIR properties was designed and synthesized using the chromenylium-cyanine platform for sensitive and selective quantification of Hg in real samples. The interaction between the probe and Hg resulted in the opening of the closed spirolactam ring of the chromenylium-cyanine platform, leading to a notable color shift from yellow to green. Concurrently, ratiometric spectral changes at 380 and 725 nm for UV-Vis and signal enhancement at 755 nm for fluorescence were observed.

Comparison of double-port laparoscopic-assisted extracorporeal suture technique and open surgical repair for Morgagni hernia.

Background/aim: We aimed to compare the results of open surgery and double-port laparoscopic-assisted extracorporeal suturing repair for the treatment of Morgagni hernia (MH).

Materials And Methods: Twenty-two patients with MH who were operated on in our clinic between January 2012 and January 2023 were included in the study. Patients were divided into two groups according to the surgical technique: open surgery (OS) (n = 14) or laparoscopic surgery (LS) (n = 8).

Expanding cyclodextrin use in normal phase and super/subcritical fluid chromatographic modes for the chiral separation of 1,4-dihydropyridines.

Cyclodextrin-based stationary phases are important chiral selectors in liquid chromatography. These chiral selectors are most commonly used in the reversed-phase mode because native cyclodextrin assumes a torus conformation with a hydrophobic cavity, facilitating inclusion complexation in aqueous environments. However, the value of native and aliphatic-derivatized cyclodextrins in other modes, such as the normal phase liquid chromatography (NPLC) or super/subcritical fluid chromatography (SFC), remains unexplored.

Evaluation of Lysosphingolipid Analysis for the Diagnosis of Lysosomal Storage Disease.

Lysosomal storage disorders (LSD) are a group of inherited inborn metabolism errors that are characterized by a deficiency in the lysosomal enzyme. In patients with suspected lipid storage disorders, confirmation of the diagnosis relies predominantly on the measurement of specific enzymatic activities and molecular genetic studies. New approaches to the measurement of lysosphingolipids have been developed that may serve as a rapid first-tier screening tests for the evaluation of lysosomal storage disorders.

Chiral superficially porous stationary phases for enantiomeric separation of condensed 1,4-dihydropyridine derivatives.

1,4-dihydropyridine (DHP) scaffold occupies a prominent position among all heterocyclic compounds owing to its versatile pharmacological properties, particularly its well-known calcium channel blocking activity. In the quest of developing new calcium channel blockers, fifty seven 5-oxo-hexahydroquinoline (HHQ) derivatives carrying DHP framework in a condensed ring system were recently synthesized as racemic mixtures. Due to their potential as drug candidates, enantiomers arising from the asymmetric center at the C-4 position of the HHQ ring were separated.

Tail-approach based design, synthesis, and molecular modeling of benzenesulfonamides carrying thiadiazole and urea moieties as novel carbonic anhydrase inhibitors.

We synthesized herein 16 compounds (SUT1-SUT16) as potential carbonic anhydrase (CA) inhibitors utilizing the tail-approach design. Based on this strategy, we connected benzenesulfonamide, the zinc-binding scaffold, to different urea moieties with the 1,3,4-thiadiazole ring as a linker. We obtained the target compounds by the reaction of 4-(5-amino-1,3,4-thiadiazol-2-yl)benzenesulfonamide with aryl isocyanates.

Comparison of autogenous and reactive type obsessive-compulsive disorders in terms of clinical characteristics: A meta-analysis study.

To our knowledge, no meta-analysis study compares sociodemographic and clinical characteristics. Investigation of the differences between the two groups in terms of these basic characteristics may provide information about the accuracy of this classification.

Comparative effects of 17% ethylenediaminetetraacetic acid and 9% etidronic acid applied with different irrigant activation techniques on the release of growth factors from dentin: in vitro study.

Background: Growth factors embedded in the extracellular matrix of the dentin play an important role in the migration, proliferation, and differentiation of dental pulp stem cells in regenerative endodontics. In regenerative endodontic treatments, the type of irrigation solution used is crucial for the release of growth factors (GFs) from the dentin matrix. This study evaluated the effectiveness of different irrigant activation techniques (IAT) using two different chelating agents, 17% ethylenediaminetetraacetic acid (EDTA) and 9% etidronic acid (HEDP), in terms of their GF release.

Smart Grid Security: An Effective Hybrid CNN-Based Approach for Detecting Energy Theft Using Consumption Patterns.

In Internet of Things-based smart grids, smart meters record and report a massive number of power consumption data at certain intervals to the data center of the utility for load monitoring and energy management. Energy theft is a big problem for smart meters and causes non-technical losses. Energy theft attacks can be launched by malicious consumers by compromising the smart meters to report manipulated consumption data for less billing.

Multivariate Approaches in Quantitative Structure-Property Relationships Study for the Photostability Assessment of 1,4-Dihydropyridine Derivatives.

1,4-dihydropyridines (1,4-DHPs) are widely recognized as highly effective L-type calcium channel blockers with significant therapeutic benefits in the treatment of cardiovascular disorders. 1,4-DHPs can also target T-type calcium channels, making them promising drug candidates for neurological conditions. When exposed to light, all 1,4-DHPs tend to easily degrade, leading to an oxidation product derived from the aromatization of the dihydropyridine ring.

Disruption of consciousness depends on insight in OCD and on positive symptoms in schizophrenia.

Disruption of conscious access contributes to the advent of psychotic symptoms in schizophrenia but could also explain lack of insight in other psychiatric disorders. In this study, we explored how insight and psychotic symptoms related to disruption of consciousness. We explored consciousness in patients with schizophrenia, patients with obsessive-compulsive disorder (OCD) with good vs.

Evaluation of clinical, laboratory, and molecular genetic features of patients with biotinidase deficiency.

Biotinidase deficiency (BD) is an autosomal recessive inherited metabolic disorder which results from the inability of biotin-dependent carboxylase enzymes to function due to the release and absorption of biotin, leading to neurological and cutaneous findings. In the present study, evaluation of demographic characteristics, clinical findings, laboratory results, molecular genetic characteristics, and genotype-phenotype correlations of cases with BD. Two hundred forty-seven cases were included in the study who were admitted to the Department of Pediatric Metabolism of Ankara Bilkent City Hospital after being identified with potential BD through the Newborn Screening Program (NBS), during family screening or based on suspicious clinical findings, or following the detection of a pathogenic variant in a BTD genetic analysis during the period of October 2020 and February 2022.
