The genera Geranium and Erodium (Geraniaceae) have been documented to possess diverse ethnopharmacological uses, including diabetes mellitus. Relevant to their ethnopharmacological use, the current study aimed to evaluate the α-glucosidase, α-amylase, acetylcholinesterase (AChE), and butyrylcholinesterase (BChE) enzyme inhibitory activity of ethanol extracts from 46 samples belonging to thirty-one species of Geranium (20) and Erodium (11) collected throughout Türkiye. The majority of the extracts displayed a marked α-glucosidase and α-amylase inhibitory activity.

Ultrasound (US)-guided suprascapular nerve block (SSNB) is a widely used procedure and while describing the US-guided SSNB in the suprascapular notch, the suprascapular fossa is often visualized and injection is performed in that location. Although it can be done in both location, to inject the right area, the terminology should be settled and the visualization of these areas which are unclear and confusing in the literature should be clarified. In this sense, we showed the course of the nerve on a cadaver and briefly describe a protocol to correctly visualize the suprascapular notch with US.

In the present study, the air pollution dynamics of the metropolitan cities of Balıkesir, Bursa, Istanbul, Kocaeli, Sakarya and Tekirdağ in the Marmara Region, which is the geographical region with the highest urban and industrial activity in Turkey, were examined for the time period between 2016 and 2019. Annual changes in the cities in terms of air pollution, which was examined with a focus on the PM parameter as indicated by United Nations (UN) Sustainable Development Goals (SDGs); differences in the cities by years; and the seasonal changes in air pollution in the cities were investigated. Additionally, mortality rates attributed to air pollution were calculated with the AirQ + software based on integrated exposure-response function recommended by the World Health Organization (WHO) and the UN using city-scale statistics of fatal disease cases that can be attributed to air pollution.

Objective:  Two different methods for fine needle aspiration biopsy (FNAB) of thyroid nodules (multi-pass conventional smear, MPCS; single-pass liquid-based cytology, SPLBC) were evaluated regarding the magnitude of nondiagnostic/unsatisfactory sampling ratio, and basic demographic and ultrasonographic (USG) factors to predict such outcome.

Methods:  One thousand FNAB patients were retrospectively assessed. Of them, 517 nodules were evaluated with the conventional smear method, and the rest were evaluated with liquid-based cytology method using the Bethesda System for Reporting Thyroid Cytopathology.
