Objectives: Hormonal changes during oral contraceptive pill (OCP) use may affect central corneal thickness (CCT) values. We aimed to evaluate the impact of OCP use on CCT values in healthy young women.
Materials And Methods: Fifty women subjects who use OCP for contraception (Group 1) and forty control subjects (Group 2) who do not use OCP were included in this prospective study. None of the patients had any history of systemic or ocular diseases. The CCT values measured by ultrasonic pachymeter (Nidek US-4000 Echoscan, Japan) and the intraocular pressure (IOP) values were measured by noncontact tonometer (Reichert 7 CR Corneal Response Technology, USA) at the time of admission to our clinic. The demographic findings and body mass index (BMI) scores of participants were also recorded.
Results: The mean ages were 32.8 ± 5.6 for OCP + patients (Group 1) and 31.3 ± 6.9 for OCP-patients (Group 2) ( = 0.28). The mean CCT values were significantly higher in Group 1 when compared to that of the Group 2 (540.9 ± 30.4 μm and 519.6 ± 35.6 μm, respectively) ( = 0.003). The mean IOP value was 14.3 ± 2.5 mmHg in Group 1 and 14.4 ± 2.7 mmHg in Group 2 ( = 0.96). The mean BMI scores were 24.4 ± 5.8 kg/m in Group 1 and 24.6 ± 3.5 kg/m in Group 2 ( = 0.83).
Conclusion: Our findings revealed that CCT values were significantly higher in patients with OCP use. Ophthalmologists should be aware of potential elevated CCT levels in these patients.

Innovation in the drying process during the roasting of cashew nut almonds has the potential to significantly improve product quality. This study aimed to investigate the drying kinetics of the almond, comparing the experimental data with the mathematical models of Fick, Page, Cavalcanti Mata, and Henderson and Pabis. The research was conducted at the Laboratory of Physical Measurements and Drying of the Academic Unit of Food Engineering at the Federal University of Campina Grande.

Objectives: Trauma-induced coagulopathy (TIC) can be fatal but preventable if recognised early. With emerging uses of rotational thromboelastometry (ROTEM) to guide transfusions in trauma, patient outcomes with TIC-defined by initial ROTEM and conventional coagulation tests (CCTs) during massive haemorrhage protocol (MHP) activations were evaluated at a primary trauma centre in British Columbia.
Methods: This retrospective observational study included adult trauma patients requiring MHP from June 1, 2020, to May 31, 2022.

Purpose To determine the corneal topographic characteristics of children with blepharokeratoconjunctivitis (BKC), a chronic inflammatory ocular surface disease involving the lid margin, conjunctiva, and cornea. Methods The corneal topography of 21 children diagnosed with BKC between March 2008 and June 2019 at a single institution were reviewed retrospectively. Pachymetry and asymmetry indices were also analyzed.

, a recently described endemic species from southern Peru, belongs to the Amaryllidaceae family and is known for its diversity of alkaloids. Amaryllidoideae have been studied for their diverse biological activities, particularly for their properties in treating neurodegenerative diseases. This work examines the alkaloidal profile using GC-MS and UPLC-MS/MS of alkaloid-enriched extracts obtained from the leaves and bulbs of and their inhibitory activity against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) enzymes.

In recent years, it has become a development trend to design multi-application luminescent materials with rare earth ion doping. In this work, a series of Eu/Sm doped self-activated NaYMgVO (NYMVO) phosphors were synthesized through a simple high-temperature solid-state reaction method. Interestingly, due to the energy transfer (ET) from the matrix to the activators, the luminescence color of the phosphors changed from turquoise to orange-red and yellow-green under near-ultraviolet (n-UV) 365 nm excitation.
