Pain is perceived not only by personal experience but also vicariously. Pain empathy is the ability to share and understand other's intentions and emotions in their painful conditions, which can be divided into cognitive and emotional empathy. It remains unclear how centrally acting analgesics would modulate brain activity related to pain empathy and which component of pain empathy would be altered by analgesics.

Background/purpose: The possibility of triggering the trigeminocardiac reflex (TCR) during oral surgery is considerably lower than that during other surgeries. A reduced heart rate (HR) of ≥20% from baseline is usually considered a diagnostical criterion for the TCR. Our automated anesthesia charting system often revealed cases of slight transient HR decrease during sedation.

Starch is stored temporarily in the leaves during the day but degraded during the night. In this study, we investigated the relationship between diurnal changes in starch content in rice leaf blades and the mRNA levels of β-amylase genes. In addition to the known plastid-type β-amylases OsBAM2 and OsBAM3, OsBAM4, and OsBAM5 were also identified as plastid targeted proteins.

Article Synopsis
  • Rice is critical for grain production, making it an ideal model to study starch biosynthesis, yet little is known about this process in rice's vegetative parts.
  • Researchers created rice mutants with an inserted gene to explore the functions of different starch synthase (SS) isozymes, particularly focusing on SSIIIb and its impact on starch in leaf sheaths and leaf blades.
  • Findings showed that SSIIIb plays a key role in synthesizing long chains of amylopectin in vegetative organs, while SSI is responsible for producing shorter chains, similar to their functions in the endosperm.

Triacylglycerols (TAGs) are the major component of plant storage lipids such as oils. Acyl-CoA:diacylglycerol acyltransferase (DGAT) catalyzes the final step of the Kennedy pathway, and is mainly responsible for plant oil accumulation. We previously found that the activity of Vernonia DGAT1 was distinctively higher than that of Arabidopsis and soybean DGAT1 in a yeast microsome assay.

The group constitutes a part of the oral flora in humans and has been reported to cause infective endocarditis, brain abscesses, sepsis, pneumonia, and peritonitis. However, the group rarely causes meningitis in children. We experienced a case of bacterial meningitis due to the group in a 14-year-old girl with Gorham-Stout disease undergoing treatment with sirolimus for skull base osteolysis and cerebrospinal fluid (CSF) leak.

CO -responsive CCT protein (CRCT) is a positive regulator of starch synthesis-related genes such as ADP-glucose pyrophosphorylase large subunit 1 and starch branching enzyme I particularly in the leaf sheath of rice (Oryza sativa L.). The promoter GUS analysis revealed that CRCT expressed exclusively in the vascular bundle, whereas starch synthesis-related genes were expressed in different sites such as mesophyll cell and starch storage parenchyma cell.

Global warming threatens food security by decreasing crop yields through damage to photosynthetic systems, especially Rubisco activation. We examined whether co-overexpression of Rubisco and Rubisco activase improves the photosynthetic and growth performance of rice under high temperatures. We grew three rice lines-the wild-type (WT), a Rubisco activase-overexpressing line (oxRCA) and a Rubisco- and Rubisco activase-co-overexpressing line (oxRCA-RBCS)-and analysed photosynthesis and biomass at 25 and 40°C.

This is a case report of a 75-year-old man scheduled for apical resection and cystectomy of odontogenic cysts involving both maxillary central incisors who presented with a previously unknown laryngeal mass that was discovered prior to intubation. Following induction and easy mask ventilation, direct laryngoscopy revealed a large mass on the right side of the glottis that impeded passage of a standard oral endotracheal tube. Successful atraumatic intubation was performed with the combination of a video laryngoscope (King Vision, Ambu Inc, Ballerup, Denmark) and a gum elastic bougie (GEB).

Photosynthetic rate at the present atmospheric condition is limited by the CO-fixing enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) because of its extremely low catalytic rate (k) and poor affinity for CO (K) and specificity for CO (S). Rubisco in C plants generally shows higher k than that in C plants. Rubisco consists of eight large subunits and eight small subunits (RbcS).

Background: Down syndrome is characterized by a variety of dysmorphic features and congenital malformations, such as congenital heart disease, gastrointestinal disease, and other conditions like leukemia and autoimmune disorders. Patients with Down syndrome are highly prone to respiratory tract infections, which might be fatal to them. However, there are only few available data on patients diagnosed with Down syndrome and agammaglobulinemia.

Transcriptional changes in primary sensory neurons are involved in initiation and maintenance of neuropathic pain. However, the transcription factors in primary sensory neurons responsible for neuropathic pain are not fully understood. Dorsal Root Ganglia Homeobox (DRGX) is a paired-like homeodomain transcription factor necessary for the development of nociceptive primary sensory neurons during the early postnatal period.

Lidocaine has been used as a local anesthetic by injection. The controlled release of lidocaine loaded into nanospheres is necessary to reduce the onset time of the anesthetic effect or increase the anesthetic analgesia duration. In this study, mesoporous silica nanoparticles (MSNs) with a large specific surface area were prepared by a sol-gel method, and the interfacial interaction between MSNs and lidocaine positively charged in aqueous solutions at different concentrations was investigated by adsorption tests, Fourier-transformed infrared spectroscopy, thermogravimetry-differential thermal analysis, and Brunauer-Emmett-Teller (BET) measurements.

Although in clinical dentistry the major method used for pain relief is oral administration of analgesics, alternative methods are available, such as transcutaneous electrical nerve stimulation (TENS), acupuncture, vibration and conditioned pain modulation (CPM), formerly termed diffuse noxious inhibitory control. The aim of the present study was to investigate the combined effects of non-noxious (TENS) and noxious (CPM) stimuli on postoperative pain after extraction of an impacted wisdom tooth. The study involved 44 patients who were scheduled to undergo impacted wisdom tooth extraction.

Background: A recent neurocognitive model of attention-deficit hyperactivity disorder (ADHD) has proposed a primary deficit in reward function as well as in executive function to account for underlying neural substrates of ADHD symptoms. Atomoxetine has been widely used as a non-stimulant medication for ADHD with little abuse liability. Although animal studies have reported that atomoxetine increases extracellular levels of both noradrenaline and dopamine in the prefrontal cortex, which receives input from a mesocorticolimbic pathway involved in reward function, there have been few studies in humans concerning the effects of atomoxetine in terms of reward function.

CO2-responsive CCT protein (CRCT) is suggested to be a positive regulator of starch biosynthesis in the leaf sheaths of rice, regulating the expression levels of starch biosynthesis-related genes. In this study, the effects of CRCT expression levels on the expression of starch biosynthesis-related enzymes and the quality of starch were studied. Using native-PAGE/activity staining and immunoblotting, we found that the protein levels of starch synthase I, branching enzyme I, branching enzyme IIa, isoamylase 1 and phosphorylase 1 were largely correlated with the CRCT expression levels in the leaf sheaths of CRCT transgenic lines.
