'Parents Are the First Tutors of Their Child': Parents' Perception of Responsibility on Practicing Speech-Language Home Program During COVID-19 Lockdown.

Background And Objectives: Some families faced difficulties accessing speech therapy in some areas of Malaysia and/or during the COVID-19 lockdown. Therefore, parent-mediated intervention could be one of the ways to solve this issue, as it has been proven to effectively improve communication skills among children with communication disorders. Hence, a Mandarin parental guidebook comprising a series of language stimulation activities was developed to explore the perception of parents of children with communication disorders, ranging from 3 to 6 years old, regarding the feasibility of (1) conducting speech-language home programs and (2) using a home-based parental guidebook as a tool to deliver a speech-language home program.

Eupalinolide B inhibits periodontitis development by targeting ubiquitin conjugating enzyme UBE2D3.

Periodontitis is a chronic periodontal inflammatory disease caused by periodontal pathogens commonly seen in adults. Eupalinolide B (EB) is a sesquiterpenoid natural product extracted from Eupatorium lindleyanum and has been reported as a potential drug for cancers and immune disorders. Here, we explored the ameliorative effects and underlying molecular mechanism of EB on periodontitis for the first time.

Removal of cyanobacterial harmful algal blooms (HABs) from contaminated local park lake using mycelial pellets.

Eutrophication and hypereutrophication in lakes foster harmful blue-green algal blooms, which pose a significant threat to the ecological health of freshwater reservoirs. This study investigated the effectiveness of the bio-flocculation approach using the fungus strain BGF4A1 to remove these harmful blooms, specifically targeting cyanobacterial species like PCC-7914. Key flocculation parameters, cyanobacterial concentrations, adsorption kinetics, and pellet morphology were explored in this research.

Cortical HFS-induced neo-Hebbian local plasticity enhances efferent output signal and strengthens afferent input connectivity.

High-frequency stimulation (HFS)-induced long-term potentiation (LTP) is generally regarded as a homosynaptic Hebbian-type LTP, where synaptic changes are thought to occur at the synapses that project from the stimulation site and terminate onto the neurons at the recording site. In this study, we first investigated HFS-induced LTP on urethane-anesthetized rats and found that cortical HFS enhances neural responses at the recording site through the strengthening of local connectivity with nearby neurons at the stimulation site, rather than through synaptic strengthening at the recording site. This enhanced local connectivity at the stimulation site leads to increased output propagation, resulting in signal potentiation at the recording site.

Umbilical Artery Thrombosis Masquerading as Single Umbilical Artery in a Stillbirth.

Umbilical artery thrombosis (UAT) masquerading as a single umbilical artery (SUA) is a rare but critical diagnostic challenge in prenatal care. We described a case of a 22-year-old primigravida with an uneventful obstetric history who presented with reduced fetal movements at 22 weeks of gestation. Ultrasound showed no gross fetal structural anomalies while umbilical artery Doppler flow imaging revealed an isolated SUA.
