Article Synopsis
  • * This study explored how brain-to-muscle and brain-to-brain connectivity changes during standing and postural sway using electroencephalography (EEG) and electromyography (EMG) in various standing positions.
  • * Results showed enhanced muscle connectivity at peak sway in specific frequency bands and identified distinct patterns of brain connectivity that support posture control, particularly under conditions requiring more balance, like narrow-base standing.

Article Synopsis
  • The study investigates how N-acetylcysteine (NAC) can disrupt extracellular polymeric substances (EPS) in bacterial biofilms, which help protect bacteria from treatments.
  • Researchers used microscopy techniques to observe NAC's effects on single cells and early biofilms of the Xylella fastidiosa bacteria.
  • The findings suggest that NAC significantly alters both soluble and tightly bound EPS, enhancing bacterial mobility and potentially aiding in the treatment of bacterial infections.

Multifactorial lifestyle approaches could be more effective than a single factor for maintaining cognitive function. This study investigated the association of combining cognitively stimulating leisure activities (CSLAs), including puzzles, quizzes, and cognitive training games, with intake of long-chain polyunsaturated fatty acids (LCPUFAs), including docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and arachidonic acid (ARA), on cognitive function in the older Japanese individuals without dementia. Participants were community-dwelling Japanese individuals without a self-reported history of dementia ( = 906, aged 60-88 years) from datasets of a 2-year longitudinal study (baseline: 2006-2008 and follow-up: 2008-2010).

Article Synopsis
  • This study investigates the effects of dysphagia rehabilitation on older patients with cardiovascular disease (CVD) in a super-aged society, emphasizing the necessity for effective management in community hospitals.
  • A retrospective review of 732 patients aged 65 and older indicated that around 55.1% needed dysphagia rehabilitation, which notably enhanced their caloric intake and BMI, along with improvements in their activities of daily living (ADL) by discharge.
  • The findings suggest that integrating dysphagia rehabilitation into cardiac care can significantly improve the quality of life for older patients with CVD, making it a crucial component of their overall treatment.

Iron (Fe) in seawater is an essential micronutrient for marine phytoplankton, and Fe deficiency limits their growth in high-nutrient, low-chlorophyll areas. The bioavailability of Fe for phytoplankton largely depends on its chemical speciation in seawater. In surface water, the reduction of Fe(III) to Fe(II) is an important step in the uptake of Fe by phytoplankton.

Campylobacter jejuni is one of the major bacterial strains that cause diarrhea in humans. It has been associated with many cases of food poisoning in Japan caused by eating raw, undercooked, and/or improperly prepared chicken meat, liver, and grilled chicken (Yakitori). Campylobacter jejuni is also known to be a preceding infectious pathogen of Guillain-Barré syndrome (GBS), which has a considerably negative health impact on humans.

Rolling walkers are common walking aids for individuals with poor physical fitness or balance impairments. There is no doubt that rolling walkers are useful in assisting locomotion. On the other hand, it is arguable that walking with rolling walkers (WW) is effective for maintaining or restoring the nervous systems that are recruited during conventional walking (CW).

We present a method for the determination of ultra-trace Te species (Te(IV) and Te(VI)) in open ocean waters. The proposed method is based on Mg(OH) coprecipitation, anion exchange resin column separation and inductively coupled plasma sector-field mass spectrometry (ICPSFMS) using a Te-enriched isotope spike. The largest advantage of the method is that the use of the spike allows accurate and precise determination when it combines with either isotope dilution or recovery correction.

We present a 76-year-old female with a 6-year history of decreased vision in the right eye and right-sided facial neuralgia. She had a T1 isointense and T2 isointense enhancing lesion in the right orbit and the middle cranial fossa on MRI examination. Granulomatous disease or meningioma was suspected, however, after removal, the tumor was identified by pathology as adenoid cystic carcinoma (ACC).

Auger electrons can cause nanoscale physiochemical damage to specific DNA sites that play a key role in cancer cell survival. Radio-Pt is a promising Auger-electron source for damaging DNA efficiently because of its ability to bind to DNA. Considering that the cancer genome is maintained under abnormal gene amplification and expression, here, we developed a novel Pt-labeled agent based on pyrrole-imidazole polyamide (PIP), targeting the oncogene MYCN amplified in human neuroblastoma, and investigated its targeting ability and damaging effects.

The present review aims to explore the potential targets/partners for future targeted radionuclide therapy (TRT) strategies, wherein cancer cells often are not killed effectively, despite receiving a high average tumor radiation dose. Here, we shall discuss the key factors in the cancer genome, especially those related to DNA damage response/repair and maintenance systems for escaping cell death in cancer cells. To overcome the current limitations of TRT effectiveness due to radiation/drug-tolerant cells and tumor heterogeneity, and to make TRT more effective, we propose that a promising strategy would be to target the DNA maintenance factors that are crucial for cancer survival.

Arachidonic acid (ARA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA), which are long-chain polyunsaturated fatty acids (LCPUFAs), as well as lutein (L) and zeaxanthin (Z), can potentially improve brain function. However, the effect of a combination of these components (LCPUFAs + LZ) on memory function in healthy older individuals remains unclear. This study aimed to determine if LCPUFAs + LZ-supplemented food could improve memory function.

Article Synopsis
  • * This study examines how adaptations from walking with force fields in one direction influence subsequent walking with force fields in the opposite direction.
  • * Findings indicate that adaptations are only partially transferred between directions, and the effects from one direction remain largely intact even after walking in the opposite direction, suggesting independent neural control mechanisms for each task.

To advance breeding techniques for the African freshwater pufferfish Tetraodon schoutedeni and observe tandem spawning closely, we monitored the reproduction of captive individuals. Eight spawning sessions (stable water temperature 24-25°C; daily light period 07:00-19:00) occurred between May 2016 and November 2017. After 65-150 min of tandem swimming (the male biting and clinging to the female's abdomen), 3-50 spherical, weakly adhesive eggs were spawned, being scattered onto the sandy substrate or water plants.

Rehabilitation based on guided walking is effective to recover activity of daily living (ADL) in frail older adults, even octogenarians. However, muscle dysfunction obviously reflects disability, and few studies have focused on ADL recovery by rehabilitation. We employed the state of muscle dysfunctions proposed by the Asian Working Group for Sarcopenia (AWGS) in 2019 and attempted to clarify the relation between the overlapping dysfunctions and the feasibility of ADL recovery after rehabilitation.
