The bony labyrinth of the inner ear houses the sensory end-organs responsible for balance (otolithic system in the utricle and saccule, and semicircular canal system) and hearing (cochlea). Study of the bony labyrinth has revealed considerable morphological diversity in the hominin lineage (semicircular canals and cochleae) and aided in reconstructing essential aspects of primate evolution, including positional behavior, audition, and phylogenic affinities. However, evidence of evolutionary change in the hominin otolithic system remains elusive.

Background: Developing anti-obesity interventions targeting appetite or food intake, the primary driver of obesity, remains challenging. Here, we demonstrated that dietary γ-aminobutyric acid (GABA) with GABA-degradation inhibitory drugs could be an anti-obesity intervention possessing strong food intake-suppressive and weight-loss effects.

Methods: High-fat (HF)-diet-induced obese mice were divided into six groups receiving either the HF diet or the 2% GABA-HF diet with daily administration of PBS or the GABA-degradation inhibitory drugs, vigabatrin and ethanolamine-O-sulfate (EOS).

Article Synopsis
  • Blood count abnormalities are common in young COVID-19 patients, with atypical lymphocytes and eosinopenia being the main changes observed in those evaluated in emergency rooms.
  • In a study of 93 children aged 0 to 10, the presence of underlying health issues significantly increased the likelihood of hospitalization, and higher neutrophil to lymphocyte ratios (NLR) were associated with severity.
  • Eosinopenia emerged as a notable predictor of disease severity in hospitalized children, suggesting that specific CBC changes can provide insights into clinical outcomes for pediatric COVID-19 cases.

Background: Uncorrected myopia is a leading cause of blindness globally, with a rising prevalence in recent decades. Pathological myopia, often seen in individuals with increased axial length (AXL), can result in severe structural changes in the posterior pole, including myopic tractional maculopathy (MTM). MTM arises from tractional forces at the vitreoretinal interface, leading to progressive macular retinoschisis, macular holes, and retinal detachment (RD).

Background: Intracranial teratomas represent a rare subset of neoplasms characterized by tissues derived from multiple germ layers within the cranial cavity. These tumors, originating from primordial germ cells, exhibit diverse clinical presentations and histopathological features. While predominantly located along the midline axis, including the suprasellar cistern and pineal region, they can also manifest in less common areas such as ventricles and hypothalamic regions.

Immune thrombocytopenia (ITP) is most common in women during their reproductive years. When a low platelet count occurs for the first time during pregnancy, the differential diagnosis includes pregnancy-specific conditions. Although ITP is the most common cause of thrombocytopenia early in pregnancy, pregnancy-related thrombocytopenia develops mainly in late gestation.

Carnosine, anserine, and homocarnosine are histidine-containing dipeptides (HCDs) abundant in the skeletal muscle and nervous system in mammals. To date, studies have extensively demonstrated effects of carnosine and anserine, the predominant muscular HCDs, on muscular functions and exercise performance. However, homocarnosine, the predominant brain HCD, is underexplored.

Article Synopsis
  • Metabolic bariatric surgery (MBS) can improve pregnancy outcomes for obese women and significantly reduce the occurrence of gestational diabetes (GD) compared to non-operated women with similar age and body mass index (BMI).
  • A study comparing pregnancies of women who had MBS to matched controls revealed a lower frequency of GD post-surgery (7.6% vs. 19%) and lower fasting blood glucose levels and birth weight for those who had the surgery.
  • However, MBS was also linked to a higher occurrence of small-for-gestational-age (SGA) babies, which became less significant after accounting for smoking habits, highlighting the need to balance benefits with potential risks associated with MBS during pregnancy.

Endophthalmitis is a severe form of purulent inflammation caused by the infection of the intraocular tissues or fluids. This infection infrequently occurs through endogenous routes, which are often correlated with major risk factors. Escherichia coli, a gram-negative rod, can cause endophthalmitis through hematogenous spread.

Background: Transcatheter aortic valve replacement (TAVR) has revolutionized the treatment of aortic stenosis. However, conduction disturbances leading to pacemaker implantation remain a common complication, increasing morbidity and mortality in these patients. Hence, measures to lower its incidence should be taken, and corticosteroid therapy could be effective by reducing inflammation caused by direct mechanical trauma to the conduction system.

Gamma-aminobutyric acid (GABA) plays a crucial role in the central nervous system as an inhibitory neurotransmitter. Imbalances of this neurotransmitter are associated with neurological diseases, such as Alzheimer's and Parkinson's disease, and psychological disorders, including anxiety, depression, and stress. Since GABA has long been believed to not cross the blood-brain barrier, the effects of circulating GABA on the brain are neglected.
