Aim: To elucidate risk factors associated with adverse perinatal outcomes in early-gestational diabetes mellitus (GDM).

Materials And Methods: A dataset of 385 early-GDM cases from a prospective cohort was analyzed. Early-GDM was diagnosed if one or more of the following criteria were met: fasting plasma glucose (PG) levels of 92-125 mg/dL, 1-h PG levels ≥180 mg/dL, and 2-h PG levels ≥153 mg/dL during a 75-g oral glucose tolerance test before 20 weeks of gestation.

Mangrove forests are increasingly recognized as vital blue carbon ecosystems due to their high carbon sequestration capacity, primarily through the accumulation of soil organic carbon (SOC). Recent research highlights that, in addition to SOC, dissolved inorganic carbon (DIC), particularly in the form of bicarbonate (HCO₃⁻), plays a crucial role in carbon sequestration by being exported from these ecosystems to adjacent coastal waters. This study aims to investigate the previously unexamined mechanisms behind bicarbonate production in mangrove soils.

Objective: To determine the optimal montage and vocalization conditions for high-gamma language mapping using stereoelectroencephalography.

Methods: We studied 12 epilepsy patients who underwent invasive monitoring with depth electrodes and measurement of auditory-naming related high-gamma modulations. We determined the effects of electrode montage and vocalization conditions of the response on the high-gamma (60-140 Hz) amplitudes.

Dietary nitrate (NO) supplementation is known to enhance nitric oxide (NO) activity and acts as a vasodilator. In this randomized crossover study, we investigated the effect of inorganic NO supplementation on the changes in calf venous volume during postural change and subsequent skeletal muscle pump activity. Fifteen healthy young adults were assigned to receive beetroot juice (BRJ) or a NO-depleted control beverage (prune juice: CON).

Several attempts for speech brain-computer interfacing (BCI) have been made to decode phonemes, sub-words, words, or sentences using invasive measurements, such as the electrocorticogram (ECoG), during auditory speech perception, overt speech, or imagined (covert) speech. Decoding sentences from covert speech is a challenging task. Sixteen epilepsy patients with intracranially implanted electrodes participated in this study, and ECoGs were recorded during overt speech and covert speech of eight Japanese sentences, each consisting of three tokens.
