In this study, new peripherally substituted symmetric zinc and magnesium phthalocyanines (4 and 5) were successfully prepared by cyclotetramerization of the tetrahydropyrimidone (THPM)-linked phthalonitrile 3. The identity of the compounds were confirmed primarily through spectroscopic analysis including NMR, FT-IR, UV-Vis and MALDI-TOF mass spectroscopy. The photophysical and photochemical properties of the synthesized phthalocyanines (Pcs) were examined using UV-Vis absorption and fluorescence emission spectroscopy techniques.

This standard operating procedure (SOP) describes an ion chromatography (IC) procedure for the major cations and anions in hydrothermal fluids. Hydrothermal fluids are aqueous solutions with a wide range of temperature, salinity, pH and ion species that can be used by microbial metabolism as electron donors and electron acceptors. Due to the high variability of the environmental physical-chemical parameters in these samples, we have developed this protocol taking into account the special features of the matrices analyzed.

Background: Many methods are used for cancer treatment, especially chemotherapy. In addition to the their therapeutic effects, chemotherapeutic drugs also have serious disadvantages, such as not being cell and tissue-specific, causing toxicity in many tissues, and developing drug resistance. Many methods, especially nanocarriers, have been designed to overcome these disadvantages.

Innovative boxing training program outperforms the traditional scapular stabilization training program in post-stroke patients.

Sci Rep

September 2024

Department of Physiotherapy and Rehabilitation, Faculty of Health Sciences, Eastern Mediterranean University, North Cyprus Via Mersin 10, Famagusta, Turkey.

Facilitating the restoration of upper limb functionality is a key objective of stroke rehabilitation. This study aimed to compare the effects of boxing and scapular stabilization training on scapular mobility, balance angle, muscle strength, motor function, and satisfaction in hemiparetic patients. A total of sixty patients were randomly assigned to one of three groups: the boxing group (BG; n = 20), the scapular stabilization group (SSG; n = 20), or the control group (CG; n = 20) which received no treatment at all.

Article Synopsis
  • The study examines if helical Tomotherapy (HT) during free breathing (FB) can be a viable treatment option for left-sided breast cancer patients who can't use the deep inspiration breath hold (DIBH) technique.
  • Using CT images from 20 patients, the researchers compared dosimetric outcomes between the HT-FB and VMAT-DIBH techniques, focusing on target coverage and the preservation of surrounding healthy tissues.
  • Results indicated that while both methods effectively covered the treatment target, HT-FB offered superior protection for the left lung and LAD, although it requires careful assessment of doses to the contralateral breast and lung.

Introduction The coronavirus disease 2019 (COVID-19) outbreak, first reported in Wuhan, China, in December 2019, quickly hit the world in just one month, causing a global public health emergency. We aimed to investigate whether the COVID-19 pandemic caused a delay in the hospital admissions of breast cancer patients and diagnosis of breast cancer, thus increasing the tumor size and the stage of the disease. Materials and methods Included in the study were patients who underwent breast cancer surgery between 01/03/2019 and 01/03/2020 (pre-COVID-19, first period) and between 01/03/2020 and 01/03/2021 (post-COVID-19, second period).
