PURPOSE: To evaluate the utility of a novel ultrasound index "combined utero-cervical index (CUCI)" in the prediction of preterm delivery. METHODS: The present prospective cohort study was conducted in Ankara Bilkent City Hospital Perinatology Clinic between January 1, 2023, and March 31, 2023. Pregnant women with uterine contractions between 24 and 36th gestational weeks but did not have dilatation or effacement were included. CUCI was calculated as: (utero-cervical angle)/(anterior cervical lip thickness + fundal thickness + lower uterine segment thickness + cervical length)...

Endometrial cancer (EC) stands as one of the most prevalent gynecological malignancies affecting women, with its incidence and disease-related mortality steadily on the rise. Disulfiram (DSF), an FDA-approved medication primarily used for treating alcohol addiction, has exhibited promising anti-tumor properties. Studies have revealed DSF's capacity for enhanced anti-tumor activity, particularly when combined with copper. The novel Copper-Cysteamine (CuCy) compound, Cu3 Cl(SR)2 (R[bond, double bond]CH2 CH2 NH2 ), showcases photodynamic effects and demonstrates significant anti-tumor potential under various conditions, including exposure to ultraviolet light, X-ray, microwave, and ultrasound...

Chirality is an important property of nature and it regulates fundamental phenomena in nature and organisms. Here, we develop a chiral electrochemical sensor based on copper-amino acid mercaptide nanorods (L-CuCys NRs) to discriminate tryptophan (Trp) isomers. The chiral L-CuCys NRs are prepared in alkaline solution based on the facile coordination reaction between the sulfhydryl groups of L-Cys and copper ions. Since the stability constant (K) of L-CuCys NRs with L-Trp (752) are much higher than that of L-CuCys NRs with D-Trp (242), the cross-linking bonds between L-CuCys NRs and L-Trp are more stable than those between L-CuCys NRs and D-Trp...

INTRODUCTION AND AIM: The C-reactive protein/albumin ratio (CAR) is an inflammatory marker that is considered to have prognostic value in many diseases. Our aim in the present study was to investigate the diagnostic performance of the CAR in determining the clinical severity of acute severe ulcerative colitis (ASUC). MATERIALS AND METHODS: A retrospective study on 200 UC patients that were admitted to the Gastroenterology unit of the Alexandria University, over an 8-year period from January 2012 to January 2020, was conducted...

PURPOSE: The aim of this study was to evaluate brain FDG PET for short- to medium-term prediction of cognitive decline, need for assisted living, and survival in acutely hospitalized geriatric patients with newly detected clinically uncertain cognitive impairment (CUCI). MATERIALS AND METHODS: The study included 96 patients (62 females, 81.4 ± 5.4 years) hospitalized due to (sub)acute admission indications with newly detected CUCI (German Clinical Trials Register DRKS00005041)...

BACKGROUND: Chronic idiopathic ulcerative colitis (CIUC) is a disease with multifactorial chronic inflammation of the colonic mucosa. Its prevalence ranges from 37.5-250/100,000 in North America to 10-500/100,000 in Europe. In Mexico, there are studies that show an increase in the frequency of new cases. The purpose of this work was to identify possible changes in CIUC behavior in a referral hospital. METHODS: New ulcerative colitis (UC) cases confirmed by histopathology from January 2007 to December 2014 were included...

INTRODUCTION AND AIMS: The 5-aminosalicylates, especially mesalazine, are the first option in the treatment of mild-to-moderate ulcerative colitis (UC). High rates of remission induction and maintenance have been observed with the new multimatrix (MMX) mesalazine formulation, mainly in patients with distal disease. Our aim was to describe the real-world experience with MMX mesalazine in patients with UC at two tertiary care centers. MATERIALS AND METHODS: A retrospective cohort study was conducted that included 142 patients with confirmed UC diagnosis, analyzed in three study groups: 1) oral MMX mesalazine as monotherapy for remission induction, 2) oral MMX mesalazine as monotherapy for remission maintenance, and 3) oral MMX mesalazine plus topical therapy for remission induction...

In cochlear implants (CI), spread of neural excitation may produce channel interaction. Channel interaction disturbs the spectral resolution and, among other factors, seems to impair speech recognition, especially in noise. In this study, two tests were performed with 20 adult normal-hearing (NH) subjects under different vocoded simulations. First, there was a measurement of word recognition in noise while varying the number of selected channels (4, 8, 12 or 16 maxima out of 20) and the degree of simulated channel interaction ("Low", "Medium" and "High")...

INTRODUCTION: Inflammatory bowel disease (IBD) is a chronic and incurable entity. Therapy with anti-TNF-α agents was the first biologic therapy approved in Mexico for IBD. New biologic agents, such as vedolizumab and ustekinumab, have recently been added, as have small-molecule inhibitors. AIM: To update the biologic therapeutic approach to IBD in Mexico with new anti-TNF-α agents and novel biologics whose mechanisms of action induce and maintain remission of Crohn's disease and ulcerative colitis (UC)...

BACKGROUND: Positron emission tomography (PET) of the brain with 2-[F-18]-fluoro-2-deoxy-D-glucose (FDG) is widely used for the etiological diagnosis of clinically uncertain cognitive impairment (CUCI). Acute full-blown delirium can cause reversible alterations of FDG uptake that mimic neurodegenerative disease. OBJECTIVE: This study tested whether delirium in remission affects the performance of FDG PET for differentiation between neurodegenerative and non-neurodegenerative etiology of CUCI...

Human ceruloplasmin (hCP) is a multi-copper oxidase with ferroxidase and amine oxidase activities. Molecular dynamics simulation (MDS) and docking analysis of biogenic monoamines with ceruloplasmin explain the role of Asp1025, Glu935, Glu272, Glu232 and Glu230 together with the binding site water molecules (referred as conserved water molecules) in the stabilization of neurotransmitter (Serotonin, Norepinephrine and Epinephrine) molecules within the binding cavity of hCP. Conserved water molecules are found at specific positions interacting with the protein structures that have sequence similarity...

Human Ceruloplasmin (hCP) is an unique multicopper oxidase which involves in different biological functions e.g., iron metabolism, copper transportation, biogenic amine oxidation ,and its malfunction causes Wilson's and Menkes diseases. MD- simulation studies of O2- bound solvated structure have revealed the role of several conserved/ semi-conserved water molecules in the hydration of type-I copper centers and their involvement to recognition dynamics of these metal centers. In O2- bound structure, hydration potentiality of CuRS (Cu1106) type-I copper center is observed to be unique, where two water molecules (W1-W2) are interacting with the metal sites, which was not found in X-ray structures of hCP...

BACKGROUND: The microphone is the first link of the sound processing chain and if there is dirt on the membrane or in the input port, the frequency response is modified. OBJECTIVE: The effect of microphone cleaning in cochlear implants (CI) was studied by measuring speech perception scores in the noise of CI users and of normal hearing (NH) subjects with a CI simulator. MATERIAL AND METHODS: Sixty-one adult CI users and 20 NH were tested. In CI subjects, speech comprehension scores in noise were compared before and after cleaning microphone ports with one of two different cleaning procedures...

BACKGROUND: Cervical cancer is the second most common women's cancer in less developed regions and it is the leading cause of cancer mortality among women in Senegal. Because of the high costs, cervical cancer prevention is very rare in developing countries and it is often based on visual inspection methods. The University of Parma (CUCI)  and the MANI association have developed a cervical cancer screening project addressed to rural Senegal communities. The aim of the project was to disseminate the cytocervical sampling technique among Senegalese nurses and midwives, as a completion to the local visual inspection method...

Ultraviolet (UV) photon detection is becoming increasingly important in the quest to understand the fundamental building blocks of our universe. Basic properties of neutrinos and Dark Matter are currently being explored through interactions with noble elements. In response to interactions with fundamental particles, these elements emit scintillation photons in the UV range. However, most available detectors have poor response in the UV so it is typically necessary to shift UV to a wavelength, matching the sensitivity of the viable detectors...

Cucurbitacins are a group of tetracyclic triterpenoids, known for centuries for their anti-cancer and anti-inflammatory properties, which are being actively investigated over the past decades in order to elucidate their mechanism of action. In perspective of being used as therapeutic molecules, a pharmacokinetic characterization is crucial to assess the affinity toward blood carrier proteins and extrapolate distribution volumes. Usually, pharmacokinetic data are first collected on animal models and later translated to humans; therefore, an early characterization of the interaction with carrier proteins from different species is highly desirable...

The CO catalytic oxidation at ambient temperature and high space velocity was studied over the Pd-Cu/MOx (MOx = TiO2 and AI203) catalysts. The higher Brunauer-Emmett-Teller area surface of the A1203 support facilitates the dispersion of Pd2+ species, and the presence of Cu2Cl(OH)3 accelerates the re-oxidation of Pd0 to Pd2+ over the Pd-Cu/Al203 catalyst, which contributed to better performance of CO catalytic oxidation. The poorer activity of the Pd-Cu/TiO2 catalyst was attributed to the lower dispersion of Pd2+ species because of the less surface area and the non-formation of Cu2CI(OH)3 species...

Novel Cu2O-CuCl composite thin film constructed by Cu2O nanoplates growing on the CuCI matrix was prepared under facile hydrothermal conditions at 120 degrees C. The phases and morphologies of the as-prepared products were characterized by energy dispersive X-ray spectroscopy (EDS), X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). The result indicated that the thickness of Cu2O nanoplates was about 100 nm. Furthermore, the photocatalytic activity of the prepared Cu2O-CuCl composite thin film for the degradation of methyl orange was investigated by UV-vis spectrophotometer, demonstrating that it possessed the higher activity...
