Article Synopsis
  • The study investigated pollution intensity and heavy metals in soil at Aksaray University, revealing varying pH levels affecting metal mobility.
  • It found that 75% of the campus area is moderately to highly polluted, particularly in student-heavy areas where lead (Pb) is concentrated.
  • Analysis showed that over half of the pollution comes from natural sources, with significant contributions from industrial and traffic activities, highlighting the need for ongoing monitoring of heavy metals on campus.

Background: This research explores the perspectives and attitudes of university students in health sciences towards aging and older adults. Given the intricate interplay of factors influencing attitudes toward aging, coupled with the demographic shift in Turkey from a youthful to an aging population, the study aims to discern how a cohort of university students perceives the aging process.

Methods: Employing a mixed-methods research strategy, which enhances the depth of data interpretation, the study utilized a questionnaire for quantitative data collection.

The powdered citrus peel, which has been replaced with sodium hydroxide, was used in this study to test how well methylene blue and reactive black 5 dyestuff absorbed one or both. To find out about the texture and surface chemistry of modified citrus peel, Fourier transform infrared spectroscopy and scanning electron microscope analyses were carried out. Fourier transform infrared spectroscopy data revealed the presence of amphoteric radicals on the modified citrus peel surface, indicating the effective adsorption of methylene blue and reactive black 5.

Background: Ulcerative colitis (UC) is a chronic inflammatory bowel disease that develops due to the impaired immune response in genetically susceptible individuals, and its etiopathogenesis is not fully elucidated. IL-17 A is a cytokine that is produced by a type of immune cell called Th17 cells and is involved in the immune response and inflammation. On the other hand, ADAMTS-1, -4, and - 5 are enzymes that are involved in the breakdown of extracellular matrix proteins, including proteoglycans, which are important components of the intestinal wall.

Background: Heterozygous gain-of-function mutations in the glucokinase (GCK) gene cause hyperinsulinaemic hypoglycaemia (GCK-HI), while loss-of-function mutations lead to a monogenic type of diabetes (GCK-MODY). We, herein, report a heterozygous GCK gene mutation in a large family with GCK-MODY and insulinoma in one individual from the same family.

Patients And Methods: The proband, an 11-year-old male, was referred for asymptomatic mild hyperglycemia (fasting glucose:121 mg/dL) and HbA1c of 6.

To avoid brain damage in newborn infants, effective tools for prevention of excessive neonatal hyperbilirubinemia are needed. The objective of this study was to evaluate a new transcutaneous bilirubinometer (JAISY). For this purpose, 930 bilirubin measurements were performed in 141 newborn infants born near-term or at term (gestational age 35-41 weeks; postnatal age 1-6 days; 71 boys; including 29 infants with darker skin) and compared to those of a previously validated instrument (JM105).

Introduction: Episodic ataxia is a clinical condition characterized by episodes of balance and coordination problems that last minutes to hours. It can be inherited or sporadic, and it can be seen sporadically in epilepsy, basilar migraine, multiple sclerosis, vertebrobasilar ischaemia, and labyrinth diseases.

Methods: In this article, we present a case of a patient who had a coincidental occurrence of episodic ataxia type 2 (EA2) and multiple sclerosis (MS) Results: The patient who had a previously unidentified heterozygous mutation in the calcium voltage-gated channel subunit alpha 1 A gene (CACNA1A).

Participants manually explored 47 solid, fluid, and granular materials and rated them according to a list of sensory and affective attributes. In principal component analyses (PCA) of sensory ratings, we extracted six dimensions: Fluidity, Roughness, Deformability, Fibrousness, Heaviness, and Granularity. PCAs on affective ratings revealed Valence, Arousal, and Dominance.

Statement Of Problem: Impression materials must be disinfected to avoid cross-contamination before they are sent to the dental laboratory. However, whether aqueous state disinfectants affect material wettability is unclear.

Purpose: The purpose of this in vitro study was to compare the efficacy of gaseous ozone and sodium hypochlorite (NaOCl) in disinfecting light-body consistency hydrophilized polyvinyl siloxane (PVS) impression specimens inoculated with a cocktail of Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Enterococcus faecalis.

Purpose: To compare the adhesion and proliferation effect of HGF-1 cells on pure titanium disks when the surfaces are unprocessed (machined surfaces after slicing) or modified with a laser.

Materials And Methods: Twenty-eight titanium disks were divided into four groups. Three surface topographies were created using an erbium fiber laser: group 1 (unidirectional application [no crosshatch]), group 2 (crosshatching in two directions), and group 3 (crosshatching in three directions).

Background: Carbon monoxide (CO) poisoning is associated with cardiac injuries or manifestations, frequently attributing to direct hypoxic damage at cellular level. For this, the aims were to evaluate the role of serum pentraxin 3 (PTX 3), ischemia-modified albumin (IMA), and myeloperoxidase (MPO) as an early biomarker for cardiac damage when compared to cardiac troponin I (cTnI) and creatine kinase-MB fraction (CK-MB) in adult patients with acute CO poisoning.

Methods: Forty patients with acute CO poisoning admitted to the emergency department.

Anaerobic biodegradation of mixed non-analogous two substrates was studied in a binary system with and without the primary substrate using an anaerobic multichamber bed (AMCBR). In the binary mixture, the biodegradation of less-degradable oxytetracycline (OTC) was restarted in the presence of more degradable benzo[a]pyrene (BaP) in the initial runs of the AMCBR, but enhanced biodegradation of the more recalcitrant OTC occurs in the later runs of the AMCBR due to enhanced biomass growth on dual substrates without the primary carbon source. The biodegradation yields of the OTC, BaP were discussed with sole-substrate systems and with the dual substrate system in the presence of the primary substrate.

Griscelli syndrome (GS) is an autosomal recessive disorder that is characterized by partial albinism of the skin and hair shaft. Prompt and early diagnosis is a crucial step for the follow up and management of GS, which would otherwise dramatically decrease the life expectancy of the patients. This case report presents the clinical course of a femoral fracture treated with closed reduction and pelvic-pedal cast, and progression of acute phase reaction during the follow up period.
