This study looked at how people in Dubai and Japan feel about interacting with a robot avatar, comparing both video presentations and live interactions. When watching videos, people in Dubai felt much more comfortable with the avatar than those in Japan, with 120 participants from each location involved in this part of the study. However, during live interactions, Japanese participants preferred interacting with a human operator rather than the robot. This highlights that cultural backgrounds shape our feelings about technology, which is important as the use of robot avatars grows. Who this helps: This research benefits developers of robotic technology and companies creating robots for various uses.

Remimazolam's Effects on Postoperative Nausea and Vomiting Are Similar to Those of Propofol after Laparoscopic Gynecological Surgery: A Randomized Controlled Trial.

2023

Journal of clinical medicine

Matsumoto A, Satomi S, Kakuta N, Narasaki S, Toyota Y +5 more

Plain English
This study looked at how effective remimazolam is at preventing nausea and vomiting after laparoscopic gynecological surgery compared to propofol, a common anesthetic. The researchers found that there were no differences in nausea and vomiting rates between the two groups at both 2 and 24 hours after surgery. This matters because it shows that remimazolam could be just as good as propofol for preventing these unpleasant side effects after surgery. Who this helps: This helps patients undergoing laparoscopic gynecological surgery.

Emergence of putative energy parasites within Clostridia revealed by genome analysis of a novel endosymbiotic clade.

2023

The ISME journal

Takahashi K, Kuwahara H, Horikawa Y, Izawa K, Kato D +4 more

Plain English
This study looked at a group of bacteria called Clostridia found in the guts of termites. Researchers discovered three new types of these bacteria that act like parasites, meaning they rely on the termites and the protists in their guts for nutrients instead of being beneficial. The genomes of these bacteria are small and lack the ability to produce many essential compounds, highlighting their parasitic nature. This finding helps us understand the complex relationships in the termite gut and suggests how some gut bacteria can evolve into parasites. Who this helps: This research benefits scientists studying gut bacteria and their interactions.

Delayed Nonimmune Anaphylaxis Caused by Ropivacaine for Preoperative Nerve Blocks: A Case Report.

A&A practice

Ishii T, Miyoshi H, Kubo T, Tsutsumi YM, Horikawa YT +1 more

Plain English
This study looked at a case where a 70-year-old man had an allergic reaction called anaphylaxis after receiving a local anesthetic called ropivacaine during knee surgery. The reaction occurred 3.5 hours after the medication was given, which is unusual, and tests confirmed ropivacaine was responsible. This finding is important because it highlights that allergic reactions can happen hours after a drug is used, which means doctors need to be aware that even drugs given earlier can cause serious reactions. Who this helps: This helps patients undergoing surgery and doctors administering anesthetics.

Glucokinase Variant Proteins Are Resistant to Fasting-Induced Uridine Diphosphate Glucose-Dependent Degradation in Maturity-Onset Diabetes of the Young Type 2 Patients.

2023

International journal of molecular sciences

Cho J, Horikawa Y, Oiwa Y, Hosomichi K, Yabe D +1 more

Plain English
This study looked at how certain variations of the glucokinase protein behave during fasting in patients with maturity-onset diabetes of the young type 2 (MODY2). Researchers found that eleven variants of the glucokinase protein had different resistance levels to degradation caused by a sugar molecule called UDP-glucose; specifically, variants with a lower ability to bind glucose were more resistant to degradation. This is important because it sheds light on how glucokinase affects insulin secretion and could help in understanding the management of related hereditary conditions. Who this helps: This helps patients with MODY2 and their doctors in managing blood sugar levels more effectively.

Remimazolam-based anesthesia with flumazenil allows faster emergence than propofol-based anesthesia in older patients undergoing spinal surgery: A randomized controlled trial.

2023

Medicine

Toyota Y, Kondo T, Oshita K, Haraki T, Narasaki S +6 more

Plain English
This study looked at whether a new type of anesthesia called remimazolam, paired with a drug that helps speed up recovery, allows older patients to wake up faster after spinal surgery compared to a more commonly used anesthesia called propofol. The researchers found that patients who received remimazolam were extubated in just 4 minutes, while those given propofol took 8 minutes (a significant difference). Additionally, all recovery measures, like opening eyes and following commands, were also quicker for the remimazolam group. Who this helps: This benefits older patients undergoing spinal surgery and their healthcare providers.

Effects of Remimazolam on Intracellular Calcium Dynamics in Myotubes Derived from Patients with Malignant Hyperthermia and Functional Analysis of Type 1 Ryanodine Receptor Gene Variants.

2023

Genes

Miyoshi H, Otsuki S, Mukaida K, Kido K, Sumii A +8 more

Plain English
This study looked at how a new anesthetic called remimazolam affects calcium levels inside muscle cells from patients who are susceptible to a serious condition called malignant hyperthermia (MH). Researchers found that myotubes from patients with specific genetic mutations related to MH reacted more strongly to remimazolam, needing a high concentration (206 µM) to show a response, which is much higher than what is typically used during surgery. This is important because it suggests that remimazolam may be safe to use in MH patients when given in typical doses, which is crucial for their medical care. Who this helps: This information benefits patients with malignant hyperthermia and their doctors during anesthesia planning.
