As lifestyle-related diseases like obesity, dyslipidemia, and non-alcoholic fatty liver disease are increasing globally, the demand for developing therapeutic agents and health foods remains high. However, there is a growing concern worldwide regarding the use of animals for biological testing. Herein, we developed a method using the silkworm, Bombyx mori , to evaluate the effects of compounds on improving obesity and lipid metabolism. A silkworm obesity and lipid metabolism disorder (SOLD) model, fed a 10% glucose diet for 72 h showed increased fat body weight and accumulation of neutral fat in the hemolymph and fat body. Administration of fenofibrate reduced neutral fat levels in the hemolymph, and epigallocatechin gallate reduced neutral fat levels in the hemolymph and fat body. Silkworms with improved lipid metabolism, exhibited activation of lipoprotein lipase in muscle tissue, and decreased activities of acetyl-CoA carboxylase, and activation of AMPK in the fat body. Furthermore, enhanced fatty acid beta-oxidation contributed to the promotion of lipolysis. These effects and mechanisms of action observed in silkworms are similar to those found in mammals. These results demonstrate the usefulness of the evaluation system in screening materials for their anti-obesity and lipid metabolism improvement effects using the SOLD model.

Background and Objectives: The purpose of this systematic review is to synthesize the influence cooling modality has on survival with and without medical complications from exertional heat stroke (EHS) in sport and military populations. Methods and Materials: All peer-reviewed case reports or series involving EHS patients were searched in the following online databases: PubMed, Scopus, SPORTDiscus, Medline, CINAHL, Academic Search Premier, and the Cochrane Library: Central Registry of Clinical Trials. Cooling methods were subdivided into “adequate” (>0.15 °C/min) versus “insufficient” (<0.15 °C/min) based on previously published literature on EHS cooling rates. Results: 613 articles were assessed for quality and inclusion in the review. Thirty-two case reports representing 521 EHS patients met the inclusion criteria. Four hundred ninety-eight (498) patients survived EHS (95.58%) and 23 (4.41%) patients succumbed to complications. Fischer’s Exact test on 2 × 2 contingency tables and relative risk ratios were calculated to determine if modality cooling rate was associated with patient outcomes. EHS patients that survived who were cooled with an insufficient cooling rate had a 4.57 times risk of medical complications compared to patients who were treated by adequate cooling methods, regardless of setting (RR = 4.57 (95%CI: 3.42, 6.28)). Conclusions: This is the largest EHS dataset yet compiled that analyzes the influence of cooling rate on patient outcomes. Zero patients died (0/521, 0.00%) when treatment included a modality with an adequate cooling rate. Conversely, 23 patients died (23/521, 4.41%) with insufficient cooling. One hundred seventeen patients (117/521, 22.46%) survived with medical complications when treatment involved an insufficient cooling rate, whereas, only four patients had complications (4/521, 0.77%) despite adequate cooling. Cooling rates >0.15 °C/min for EHS patients were significantly associated with surviving EHS without medical complications. In order to provide the best standard of care for EHS patients, an aggressive cooling rate >0.15 °C/min can maximize survival without medical complications after exercise-induced hyperthermia.

Oxazole, a versatile and significant heteroarene, serves as a bridge between synthetic organic chemistry and applications in the medicinal, pharmaceutical, and industrial fields. Polycyclic aromatic compounds with amino groups substituted at the 2-position of an oxazole, such as 2-aminonaphthoxazoles, are expected to be functional probes, but their synthetic methods are extremely limited. Herein, we describe electrochemical reactions of 3-amino-2-naphthol or 3-amino-2-anthracenol and isothiocyanates in DMSO, using a graphite electrode as an anode and a platinum electrode as a cathode in the presence of potassium iodide (KI), which afford N-arylnaphtho- and N-arylanthra[2,3-d]oxazol-2-amines via cyclodesulfurization. This reaction is the first example of synthesis of 2-aminoxazole-based polycyclic compounds using an electrochemical reaction. An examination of the spectroscopic properties of polycyclic oxazoles revealed that the λabs value of the tetracyclic oxazoles was redshifted relative to that of the tricyclic oxazoles. Moreover, synthesized naphthalene/anthracene-fused tricyclic and tetracyclic oxazoles exhibited extended π-conjugated skeletons and fluoresced in the 340–430 nm region in chloroform.

Neck hair-thread tourniquet syndrome (NHTTS) is a rare condition that can be a pediatric emergency, occurring when a hair or thread becomes tightly wrapped around a body part, leading to vascular or tissue damage. NHTTS commonly affects infants and young children and can result in severe complications if not promptly diagnosed and treated. The unusual nature of this event, the diffuse petechial hemorrhage on the face, and the presentation of ligature marks extending around the neck led us to admit the child to the general pediatric ward for follow-up and further investigation of the possibility of non-accidental trauma. Co-sleeping is a common cultural practice in Japan where parents sleep in close proximity to their infants. This case report aims to raise awareness among pediatricians and parents about the possibility of NHTTS occurring in infants who co-sleep, particularly when a strand of hair becomes entangled around their neck, about the early detection and appropriate management of NHTTS. And we also summarize the reported NHTTS cases.

Heterocyclic aryl selenides have recently attracted considerable research interest owing to their applications in biological and pharmaceutical fields. Herein, we describe a simple and general synthesis of 3-selanylindoles via a novel regioselective C–H selenation of indoles using a bismuth reagent as a catalyst. The reactions of indoles with diselenides in the presence of 10 mol% BiI3 at 100 °C in DMF afforded the corresponding 3-selanylindoles in moderate-to-excellent yields. The reaction proceeded efficiently under aerobic conditions by adding only a catalytic amount of BiI3, which was non-hygroscopic and less toxic, and both selanyl groups of the diselenide were transferred to the desired products.

Pd-catalyzed regioselective C–H arylation is a useful tool for the chemical modification of aromatic heterocycles and 2-arylbenzofuran derivatives are of interest as biologically active substances. Herein, the reaction of triarylantimony difluorides with benzofurans under aerobic conditions in 1,2-DCE, using 5 mol% Pd (OAc)2 and 2 eq. of CuCl2 at 80 °C, produced a variety of 2-arylbenzofurans in moderate-to-high yields. The reaction is sensitive to the electronic nature of the substituents on the benzene ring of the triarylantimony difluorides: an electron-donating group showed higher reactivity than an electron-withdrawing group. Single crystal X-ray analysis of tri(p-methylphenyl) antimony difluoride revealed that the central antimony atom exhibits trigonal bipyramidal geometry.

The objective of this study is to prepare cationized gelatin nanospheres (cGNS) incorporating a molecular beacon (MB), and visualize cellular apoptosis. Two types of MB to detect the messenger RNA (mRNA) of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) (GAP MB), and caspase-3 (casp3 MB) were incorporated in cGNS, respectively. MB incorporated in cGNS showed the DNA sequence specificity in hybridization. The cGNS incorporation enabled MB to enhance the stability against nuclease to a significantly great extent compared with free MB. The cGNS incorporating GAP MB were internalized into the KUM6 of a mouse bone marrow-derived stem cell by an endocytotic pathway. The cGNS were not distributed at the lysosomes. After the incubation with cGNS, the cell apoptosis was induced at different concentrations of camptothecin. No change in the intracellular fluorescence was observed for cGNS GAPMB . On the other hand, for the cGNS casp3MB , the fluorescent intensity significantly enhanced by the apoptosis induction of cells. It is concluded that cGNS incorporating MB is a promising system for the visualization of cellular apoptosis.

A 39-year-old man presented to the emergency department with a 7-day history of fever and rash. He reported same-sex relationships involving condomless anal sex, and did not use pre- or postexposure HIV prophylaxis. Physical examination found a temperature of 38 degrees C, cervical lymphadenopathy, mucosal ulceration on his tongue and a maculopapular rash on his face, neck and anterior chest. Suspecting primary HIV infection, a rapid plasma reagin test was performed, which returned a negative result. A chemiluminescent immunoassay was positive for HIV antibodies, but the reactive immunoassay using Western blotting showed no reactivity.

Spatial reorganization of metabolic enzymes to form the “metabolic enzymes transiently assembling (META) body” is increasingly recognized as a mechanism contributing to regulation of cellular metabolism in response to environmental changes. A number of META body-forming enzymes, including enolase (Eno2p) and phosphofructokinase, have been shown to contain condensate-forming regions. However, whether all META body-forming enzymes have condensate-forming regions or whether enzymes have multiple condensate-forming regions remains unknown. The condensate-forming regions of META body-forming enzymes have potential utility in the creation of artificial intracellular enzyme assemblies. In the present study, the whole sequence of yeast pyruvate kinase (Cdc19p) was searched for condensate-forming regions. Four peptide fragments comprising 27–42 amino acids were found to form condensates. Together with the fragment previously identified from Eno2p, these peptide regions were collectively termed “META body-forming sequences (METAfos).” METAfos-tagged yeast alcohol dehydrogenase (Adh1p) was found to co-localize with META bodies formed by endogenous Cdc19p under hypoxic conditions. The effect of Adh1p co-localization with META bodies on cell metabolism was further evaluated. Expression of Adh1p fused with a METAfos-tag increased production of ethanol compared to acetic acid, indicating that spatial reorganization of metabolic enzymes affects cell metabolism. These results contribute to understanding of the mechanisms and biological roles of META body formation.

To the Editor: Russell et al. (Sept. 29 issue) 1 report significantly better glycemic control with the use of a bionic pancreas than with standard care in patients with type 1 diabetes. The trial included participants with a wide range of clinical, demographic, and economic characteristics. A benefit of the bionic pancreas as compared with other semiautomated insulin-delivery systems is simple initialization of therapy only on the basis of body weight, so that training on the use of the device is minimal. Thus, such a device might be very effective in medically underserved patients or those who have not previously used . . .
