An effective, dual drug(DD) loaded nanocarrier system (nano particle(NP), quantum dots(QDs)) having two active substances was aimed to develop for the treatment of fibrosarcoma. Zinc oxide(ZnO) QDs were produced using zinc acetate dehydrate as a precursor, were incorporated with chitosan(Ch), and finally decorated with PEG-linked folic acid and were found to be effective after imatinib mesylate(IM) and dexketoprofen trometamol(DT) were loaded. Characterisations, drug releases, cell toxicities, penetrations through cell lines and animal tests of the prepared nanosystems were performed.

Background: Clinical training during the COVID-19 pandemic is high risk for medical students. Medical schools in low- and middle-income countries (LMIC) have limited capacity to develop resources in the face of rapidly developing health emergencies. Here, a free Massive Open Online Course (MOOC) was developed as a COVID-19 resource for medical students working in these settings, and its effectiveness was evaluated.

Objectives: Appropriate antibiotic therapy and prevention of cross-contamination are the most important subjects in tuberculosis (TB) control. The aim of this study was to investigate the major phylogenetic clades and transmission rate of multidrug-resistant (MDR) Mycobacterium tuberculosis isolates (n = 200) from patients with TB in Sivas and Konya Provinces of Turkey.

Methods: The phylogenetic relationship among the isolates was investigated by spoligotyping method.

The main challenges in treating cancer using chemotherapeutics are insufficient dose at the target site and the development of drug resistance, while higher doses can induce side effects by damaging nontarget tissues. Combinatorial drug therapy may overcome these limitations by permitting lower doses and more specific targeting, thereby mitigating drug resistance and nontarget side effects. Recent reports indicate that nonsteroidal anti-inflammatory drugs (NSAIDs) have anticancer potential and can be used together with conventional chemotherapeutics to improve efficacy and safety.

This study aims to investigate and compare the effects of insulin and embryonic stem-cell (ESC) loaded liposomes (LPs) and nanocochleate formulations and their PEGylated forms on the glucose levels. All formulations were characterized considering particle size, zeta potential, polydispersity index and encapsulation efficiencies. insulin that releases from the formulations was determined using Franz-type diffusion cells.

Nanoparticulate systems have been receiving a significant attention especially for the treatment of cancer but one of the main hurdles is to produce these developed and high-tech nanosystems in large quantities. Anticancer drug formulations are generally designed for parenteral administrations but oral administration is still the most convenient route. In this study, orally applicable nano-sized chitosan nanoparticles (NPs) were successfully prepared using Nano Spray Dryer.

The purpose of this study is to evaluate the effects of eye traumas on mental health and quality of life of children, adolescents, and their parents. Medical records of 20 children and adolescents presented with blunt and open eye injuries between June 2009 and May 2014 were reviewed. Demographics of patients, timing and type of trauma, findings of initial examination, and medical and surgical interventions applied were recorded.

Liposome (spherical vesicles) and cochleate (multilayer crystalline, spiral structure) formulations containing raloxifene have been developed having dimethyl-β-cyclodextrin (DM-β-CD) or sodium taurocholate (NaTC). Raloxifene was approved initially for the treatment of osteoporosis but it is also effective on breast tissue and endometrial cells. Raloxifene inhibits matrix metalloproteinase-2 (MMP-2) enzyme, which is known to be responsible for tumor invasion and the initiation of angiogenesis during the tumor growth.

Purpose: To compare the effects of bevacizumab applied either subconjunctivally or topically, in a rat model of corneal neovascularization induced by alkali burn.

Methods: The right corneas of 24 Wistar-Albino rats were cauterized with silver nitrate sticks. The rats were divided randomly and equally into three groups: no treatment control (n=8), subconjunctival bevacizumab treatment (n=8), and topical bevacizumab treatment (n=8).

Background: Efforts are made to enhance in-class learner engagement because it stimulates and enhances learning. However, it is not easy to quantify learner engagement. This study aimed to develop and validate an observation tool for instructor and student behaviors to determine and compare in-class learner engagement levels in four different class types delivered by the same instructor.

Purpose: To detect the abnormalities of the anterior visual pathways in children with amblyopia with diffusion tensor imaging.

Methods: Ten children with unilateral amblyopia, 5 children with bilateral amblyopia, and 10 control children were treated using diffusion tensor imaging scanning in this institutional practice. Fractional anisotropy and mean diffusivity values were analyzed using diffusion tensor imaging in the prechiasmatic and chiasmatic regions.

Team-based learning (TBL) is an interactive and analytic teaching strategy. TBL is a learner-centered strategy that uses a very structured individual and group accountability process and requires small groups to work together to solve problems. This study served to investigate whether the TBL concept could be modified and adopted to the fifth-year cornea module of an ophthalmology course.

Wild animals, including wild boars, are suitable for use as bioindicators. The aim of this study was to evaluate the concentrations of selected essential (Co, Cu, Fe, Se, Zn) and non-essential (As, Cd, Pb) potentially toxic trace elements in various tissues (hair and hoof) of wild boars hunted in the vicinity of Antalya province in Turkey, in relation to hunting seasons. Concentrations in mg/kg on dry weight basis were determined as 0.
