Mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome is one of the most common mitochondrial disorders, typically presenting with symptoms before the age of 40. Epileptic seizures are a common manifestation, with both focal and generalized seizures being observed. EEG findings can be variable, with the most common patterns being slow background activity followed by epileptiform discharges.

Background: The lung cancer is the leading cause of death worldwide. Although methods such as surgery, chemotherapy, radiotherapy, and immunotherapy are used for treatment, these treatments are sometimes inadequate. In addition, the number of chemotherapeutic agents used is very limited, and it is very important to use new natural agents that can increase the effect of these methods used in treatment.

Plate tectonics predicts that mountain ranges form by tectono-magmatic processes at plate boundaries, but high topography is often observed along passive margins far from any plate boundary. The high topography of the Scandes range at the Atlantic coast of Fennoscandia is traditionally assumed isostatically supported by variation in crustal density and thickness. Here we demonstrate, by our Silverroad seismic profile, that the constantly ~44 km thick crust instead is homogenous above the Moho, and Pn-velocity abruptly change from 7.

Within the scope of this study, a polymer-based optical sensor that can polymerize under UV radiation and produce fluorescence when suitable functional monomers and crosslinkers were prepared for aluminum determination in yogurt, soybean flour, and meat samples. Parameters such as operating range, pH, sensitivity, selectivity, determination limit, and foreign ion effect were thoroughly investigated to validate the developed method and characterize this polymer-based membrane. The designed sensor has wavelengths of 322 nm for fluorescence excitation and 356 nm for emission, respectively.

Article Synopsis
  • The study aimed to compare the detection rates of breast cancer-related lymphedema (BCRL) using two methods: perometer and circumferential measurements, in patients who had breast cancer surgery.
  • A total of 101 female patients were monitored over 12 months, revealing that 34.7% showed signs of subclinical BCRL using circumferential measures, while 23.8% did so via perometer, with no significant difference in quality of life or functionality between those with and without subclinical lymphedema.
  • The researchers recommend regular monitoring for BCRL by the same healthcare provider and educating patients to enable early detection and intervention.

Objectives: Acrodermatitis dysmetabolica (AD) is a dermatologic manifestation associated with inherited metabolic disorders (IMDs), distinct from acrodermatitis enteropathica, which occurs solely due to zinc deficiency.

Case Presentation: This report presents two pediatric cases: a 30-month-old girl with maple syrup urine disease (MSUD) experiencing AD secondary to severe isoleucine deficiency due to a protein-restricted diet, showing improvement with dietary adjustments, and a 2.5-month-old boy infant with propionic acidemia (PA) who developed AD alongside septic shock, which progressed despite intervention.

Article Synopsis
  • The study aimed to examine how cigarette smoking impacts the surface roughness and color change of three types of dental resins, including both additively and subtractively manufactured options.
  • After smoking simulations over 30 days, the Formlabs resin showed significantly less discoloration compared to its counterparts, while the surface roughness of the Dentafab resin increased notably.
  • Ultimately, all tested materials demonstrated an overall unacceptable color change, with no direct correlation found between surface roughness and discoloration due to smoking; however, the 3D resin materials are still recommended for clinical use.

Context: Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have recently emerged in assessing pheochromocytomas and paragangliomas (PPGLs). However, their combined use with PASS scale has not yet been explored.

Objective: Our goal was to investigate the prognostic values of NLR and PLR and incorporate the PASS score into our analysis.

Although sodium-glucose cotransporter-2 inhibitors (SGLT2i) are known to reduce the incidence of atrial fibrillation (AF) and AF-related adverse events, evidence on their prognostic effect in patients undergoing catheter ablation (CA) for AF is limited. In a single-center, 614 patients (mean age 58.1±9.

Highly selective inhibitors of cyclin-dependent kinase 4 and 6 (CDK4/6is) have emerged as a standart of care for first- and second-line therapies in combination with endocrine therapy (ET) for HR+/HER2- metastatic breast cancer (MBC) patients. It has been reported that combination therapy is more effective than ET alone and is safe in elderly patients as well as young patients. Nevertheless, elderly and very old patients with HR+/HER2-MBC treated with CDK4/6 inhibitor (CDK4/6i) combinations are relatively underrepresented in randomized controlled trials.

The mechanism of the base-catalyzed thiol-epoxide stage of the thiol-ene/thiol-epoxide curing process was investigated using quantum chemical tools. This study searched for conventional tertiary amines with low to medium basicity as initiators to control reaction rates and tailor industrial applications. Challenges arise from the stronger basicity of initiators, leading to an uncontrollable and short curing application period.

Subcutaneous emphysema, caused by the presence of air or gas in subcutaneous tissues, can be infectious or noninfectious. A thorough clinical evaluation, including both physical examination and radiological imaging, is required to distinguish benign subcutaneous emphysema from necrotizing soft tissue infections. In this article, we report a 12-year-old female patient with benign subcutaneous emphysema of the upper extremity and highlight the importance of an accurate diagnosis to avoid unnecessary surgical intervention.

Purpose: To investigate the effects of varicocelectomy on premature ejaculation (PE) in patients with varicocele and infertility.

Methods: A total of 82 sexually active patients aged 18 years or over who had undergone microscopic subinguinal varicocelectomy with a clinical diagnosis of varicocele in 14 urology clinics between October 2021 and March 2023 with primary infertility were evaluated prospectively Patients were evaluated using the Turkish validated form of the 'Premature Ejaculation Diagnostic Tool' (PEDT) scale. A PEDT score of 11 or above was taken to indicate the presence of PE.

Multiple primary lung cancers (MPLC) are defined as lung cancers that develop at the time of primary lung cancer detection (synchronous) or during the follow-up period (metachronous). The incidence of MPLC is increasing due to the early detection of lesions by widespread screening methods, improved surgical, medical, and radiation treatment options, and increased survival. We present a case of a patient who was operated on in our clinic and diagnosed with primary lung cancer for the third time with different histopathology.

The fact that free-living amoebae of the genus Acanthamoeba can live in many different environments causes these protozoa to have different interactions with other microorganisms. Investigation of Acanthamoeba-pathogenic bacteria interaction is important for the discovery of new antibacterial agents that can be used against pathogenic bacteria. In this study, it was aimed to investigate the antibacterial effect of cell-free supernatants obtained from Acanthamoeba against some pathogenic bacteria.
