Hyperreactio luteinalis (HL) and ovarian hyperstimulation syndrome during pregnancy are both benign conditions where the ovaries are enlarged with presence of multiple thin-walled cysts. The differential diagnosis is ovarian malignancy. Hyperandrogenism with resultant maternal virilisation could be seen in some cases of HL as well as in androgen secreting tumours.

We report a 27-year-old female patient with SHiP at 31 weeks of gestation who was referred to a tertiary care hospital in Muscat, Oman, in 2019, with right iliac fossa pain, pallor and tachycardia. Radiological investigations revealed intraperitoneal bleeding and a right adnexal haematoma.

The approach includes the study of EEG (electroencephalogram) signal features acquired in a spatial attention task. The process comprises of EEG feature selection based on the feature distribution, followed by the stepwise discriminant analysis- (SDA-) based channel selection.

Methods: This retrospective cohort study included 2,652 pregnant Omani women who delivered at the Royal Hospital, Muscat, Oman, between November 2011 and April 2012. The patients' electronic medical records were reviewed for antenatal, intrapartum and postpartum data.
Selective visual attention is the ability to selectively pay attention to the targets while inhibiting the distractors. This paper aims to study the targets and non-targets interplay in spatial attention task while subject attends to the target object present in one visual hemifield and ignores the distractor present in another visual hemifield. This paper performs the averaged evoked response potential (ERP) analysis and time-frequency analysis.

The electroencephalogram (EEG) signals are highly complex, nonlinear, and nonstationary in nature. The characteristics of the signal vary with the age and mental state of the subject.
View Article and Find Full Text PDFThe complex, nonlinear and non-stationary electroencephalogram (EEG) signals are very tedious to interpret visually and highly difficult to extract the significant features from them. The linear and nonlinear methods are effective in identifying the changes in EEG signals for the detection of depression. Linear methods do not exhibit the complex dynamical variations in the EEG signals.

The primary aim of this study is to compare the sensing characteristics, including impedance or resistance, capacitance, hysteresis, recovery and response times, and stability with respect to relative humidity, frequency, and temperature, of different materials. Various materials, including ceramics, semiconductors, and polymers, used for sensing relative humidity have been reviewed.
