Autistic/ADHD individuals are increasingly recognised as a valid minority group, with consistent research demonstrating a higher prevalence of co-occurring mental health conditions such as PTSD, anxiety, depression, substance use, and eating disorders among other mental health challenges. Due to this, there is increasing focus on the adaptations required for Autistic and ADHD individuals of current therapeutic approaches such as Schema Therapy. Particular emphasis when creating these adaptations needs to include looking at the developmental experiences, social influences, and continued adversity faced by Autistic and ADHD individuals across the lifespan, and how the narrative around Autism and ADHD within psychotherapy in general needs to change.

Article Synopsis
  • * Results showed that smaller voxel sizes (0.1- and 0.2-mm) yielded good to excellent reliability for measurements, with no significant differences found in linear measurements and varying results in volumetric measurements, particularly in pulp volume.
  • * Larger voxel sizes (0.4-mm) led to decreased reliability and repeatability for both linear and volumetric measurements, highlighting the importance of choosing smaller voxel sizes for accurate dental imaging.

Corrosive esophageal burn (CEB) is a disease with high mortality and morbidity rates. The aim of this study was to determine the efficacy of castor oil, in preventing stricture development at the experimental CEB model. In addition to studying standard histopathological damage data, neopterin, IL-33, and ST-2 proteins were also studied for the first time.

  • Morphea is a rare autoimmune disease affecting the skin and subcutaneous tissues, with this study analyzing 78 patients to explore its demographic, clinical, and histological characteristics between 2016 and 2022.
  • The plaque type was the most common clinical presentation (87.5%), with significant histopathological findings such as complete homogenization of dermal collagen (100%) and significant loss of skin appendages (98.7%).
  • Key observations included varying histopathological features and a notable association of certain signs in lower extremity lesions, suggesting morphea’s complex diagnosis may require careful clinical correlation.

Article Synopsis
  • Liposomes, also known as liposomes, are used in the cosmeceutical industry to enhance the delivery of active ingredients like ceramides, which help restore the skin barrier and treat conditions such as eczema.
  • Transethosomes, a special type of liposome containing ethanol and edge activators, have been shown to effectively penetrate the skin barrier for topical applications.
  • A study evaluated a transethosome formulation with ceramide 3, finding that it did not significantly affect the physical properties of transethosomes, and that loading efficiency was higher for lipophilic compounds compared to hydrophilic ones, regardless of ceramide presence.

Each breast cancer is a heterogeneous tumour with different clinicopathological feature, and thus they all have different prognoses. Tumour budding (TB), considered as the first step in tumour metastasis, is the most critical factor for poor prognosis and is associated with the epithelial-mesenchymal transition (EMT). Tumour budding and its clinicopathological features in invasive breast carcinoma of no special type (NST).

The validity and clinical significance of the characteristics of borderline personality disorder (BPD) in adolescents are increasingly being recognized. The persistence of BPD characteristics in adolescence is high and is associated with negative interpersonal, academic, professional, and financial outcomes. In the literature, BPD characteristics observed in children and adolescents are explained with psychodynamic theories, developmental models, and evolutionary approaches.

Introduction: Peripheral blood stem cell (PBSC) collection via apheresis requires the administration of granulocyte colony-stimulating factor (filgrastim) to stem cell donors. Several reports have shown that filgrastim administration and apheresis procedure induce a hypercoagulable state across PBSC collection, which might predispose certain donors to thrombotic complications.

Methods: We evaluated the hemostatic functions of healthy allogeneic stem cell donors by rotational thromboelastometry (ROTEM).

Introduction: Cytological specimens, such as fine needle aspirations (FNAs) and exfoliative cytology samples, are minimally invasive options for diagnostic purposes. Liquid-based cytology (LBC), originally designed for cervical cytology, has gained prominence as an alternative technique for non-gynecological cytology. Immunocytochemistry (ICC) is an ancillary method used when diagnosis becomes challenging due to morphological overlap or the need for cellular origin clarification.

Pseudoexfoliation syndrome (PEX) is characterized by the accumulation of abnormal extracellular matrix material in ocular and non-ocular tissues, including blood vessel walls. Clot-forming dysfunction might be responsible for venous thrombosis in PEX. We investigated global coagulation, the proteome, and functions of platelets in PEX patients and aimed to determine prognostic biomarkers for thrombosis risk in PEX.

Objectives: Intraoperative electron radiotherapy (IOERT) applied as boost to the tumor bed during breast conserving surgery is advantageous in terms of local recurrence in breast cancer patients. In addition, it has other advantages over the adjuvant boost RT such as no risk of tumor bed change, ease of sequencing radiotherapy chemotherapy, and reduced workload of the radiotherapy clinic. This study aimed to evaluate the long-term results of our patients who were treated with this method in our institution and are still being followed up.

The effect of Ce addition to the Cr-free Al-promoted Cu-Fe oxide-based catalysts is investigated. Catalyst characterization (X-ray diffraction (XRD), in situ Raman spectroscopy, high-sensitivity low-energy ion scattering (HS-LEIS), Brunauer-Emmett-Teller (BET) analysis), CO-temperature-programmed reduction chemical probing, and steady-state WGS activity reveal that (i) in the absence of Al, Ce addition via coprecipitation has a detrimental effect on the catalytic activity related to the poor thermostability and formation of less active Ce-Cu-O NPs, (ii) the addition of Ce via coprecipitation also does not improve the performance of the CuAlFe catalyst because of the formation of a thick CeO overlayer on the active Cu-FeO interface, and (iii) impregnation of Ce onto the CuAlFe catalyst exhibits significant improvement in catalytic performance due to the formation of a highly active CeO-FeO-Cu interfacial area. In summary, Al does not surface-segregate and serves as a structural promoter, while Ce and Cu surface-segregate and act as functional promoters in Ce/CuAlFe mixed oxide catalysts.

Sickle cell disease (SCD) is an inherited hemoglobinopathy characterized by chronic anemia, intravascular hemolysis, and the occurrence of vaso-occlusive crises due to the mechanical obstruction of the microcirculation by poorly deformable red blood cells (RBCs). RBC deformability is a key factor in the pathogenesis of SCD, and is affected by various factors. In this study, we investigated the effects of adenylyl cyclase (AC) signaling pathway modulation and different phosphodiesterase (PDE) modulatory molecules on the deformability and mechanical stress responses of RBC from SCD patients (HbSS genotype) by applying 5 Pa shear stress with an ektacytometer (LORRCA).

The capacity of the Young Schema Questionnaire (YSQ) to predict psychopathology in specific clinical groups has consistently produced mixed findings. This study assessed three versions of the Young Schema Questionnaire (YSQ), including the long form (YSQ-L3), short form (YSQ-S3), and the recent Rasch-derived version, the YSQ-R, and their subscales, in predicting psychological distress in three different psychiatric groups and a non-clinical group. Test equating techniques were first applied to derive a common metric to ensure that each YSQ version was directly comparable.

Intracellular signaling mechanisms in red blood cells (RBCs) involve various protein kinases and phosphatases and enable rapid adaptive responses to hypoxia, metabolic requirements, oxidative stress, or shear stress by regulating the physiological properties of the cell. Protein phosphorylation is a ubiquitous mechanism for intracellular signal transduction, volume regulation, and cytoskeletal organization in RBCs. Spectrin-based cytoskeleton connects integral membrane proteins, band 3 and glycophorin C to junctional proteins, ankyrin and Protein 4.
