Residual intravenous foreign bodies following hand trauma are relatively rare; only a few previous reports of this situation are available. It has been reported that foreign bodies often migrate to the heart and atrium dextrum. Herein, we report a recent case of needle breakage in the dorsal vein of the hand that was removed with lignification using an intraoperative C-arm fluoroscopy machine and tape tourniquet to avoid proximal movement during removal.

Background: The perforator flap has garnered significant interest since its inception due to its advantage of not needing a vascular network at the deep fascial level. Perforator flaps are commonly utilized in different flap transplant surgeries, and the thigh flap is presently the most widely used perforator flap. Is it possible for the calf to replace the thigh as a more suitable site for harvesting materials? Currently, there is a lack of relevant anatomical research.

  • A study was conducted in minority areas of China to assess college students' knowledge, attitudes, and practices (KAP) regarding COVID-19 and their psychological wellbeing.
  • The study found that while 94.95% of students had a positive attitude towards COVID-19 prevention, only 24.11% demonstrated adequate knowledge and more than half engaged in preventive behaviors.
  • Additionally, male students showed higher levels of depression and stress compared to female students, indicating a need for improved health education and support in minority areas.

(oak) is an important economic and ecological tree species in the world, and it is the necessary feed for oak silkworm feeding. Chloroplasts play an important role in green plants but the codon usage of oak chloroplast genomes is not fully studied. We examined the codon usage of the oak chloroplast genomes in detail to facilitate the understanding of their biology and evolution.

  • Controlling pore size in porous organic polymers (POPs) is challenging due to disorder in their linking modes.
  • The researchers developed a molecular cage-based POP (TPP-pOMC) using organic molecular cages (OMCs) that have fixed cavities and high reactivity, enabling better structural design.
  • TPP-pOMC exhibited improved pore channels and significantly increased BET surface area and CO adsorption capacity compared to traditional POPs.

  • The Yao silkworm, unique for producing yellow flat plate silk, has been cultivated exclusively by the Baiku Yao ethnic group in Guangxi, China, for a millennium.
  • Recent research sequenced the mitochondrial genomes of five Yao silkworm strains and ten domestic silkworm strains, revealing similarities in their genetic structures and a shared evolutionary ancestor.
  • Phylogenetic analyses suggest that the Yao silkworm is an ancient lineage of the domestic silkworm, highlighting its significance in understanding silkworm evolution.

The corpus allatum (CA) is an endocrine organ of insects that synthesizes juvenile hormone (JH). Yet little is known regarding the global gene expression profile for the CA, although JH signaling pathway has been well-studied in insects. Here, we report the availability of the transcriptome resource of the isolated CA from the final (fifth) instar larvae of the silkworm, Bombyx mori when the JH titer is low.

  • - This study presents the complete mitochondrial genome of the Guérin-Méneville strain Dingzhou_1, a silkworm used in silk production in North Korea, which is 15,573 base pairs long and includes 37 mitochondrial genes.
  • - The mitochondrial DNA features a 553-base pair A+T-rich area with tandem repeat units, similar to other inbred silkworm strains from China.
  • - Phylogenetic analysis indicates that the Dingzhou_1 strain from North Korea is closely related to the Chinese Liaoning population, implying that the oak silkworms in North Korea may have originated from China.

Here, we reported the complete mitochondrial genome of Guérin-Méneville (1861) collected in Heilongjiang Province, China. The mitochondrial genome is 15,341 bp and encodes 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes. Sequence comparison identified 22 SNVs in the mitochondrial genomes between Chinese and Korean populations, indicating a low intraspecific variation between the two populations .

Backgrounds: Liver hepatocellular carcinoma (HCC) is one of the most malignant tumors, of which prognosis is unsatisfactory in most cases and metastatic of HCC often results in poor prognosis. In this study, we aimed to construct a metastasis- related mRNAs prognostic model to increase the accuracy of prediction of HCC prognosis.

Methods: Three hundred seventy-four HCC samples and 50 normal samples were downloaded from The Cancer Genome Atlas (TCGA) database, involving transcriptomic and clinical data.

The Chinese oak silkworm, Antheraea pernyi, has not only been semi-domesticated as an important economical insect but also used for genetic research. The female moths of A. pernyi employ a pheromone blend containing (E,Z)-6,11-hexadecadienal (E6,Z11-16:Ald), (E,Z)-6,11-hexadecadienyl acetate (E6,Z11-16:OAc), and (E,Z)-4,9-tetradecadienyl acetate (E4,Z9-14:OAc).

Article Synopsis
  • Researchers studied bacterial communities in the midgut and midgut contents of two economically important silkworms: Antheraea pernyi and Bombyx mori.
  • They found that the midgut has a significantly more diverse bacterial composition than the midgut contents, which include food particles and digestive fluids.
  • This study is the first to compare these bacterial communities in insects, and its findings may help understand the functional differences within the midgut.

  • The study focuses on a specific gene, ApESR16, which encodes a 16 kDa protein in the Chinese oak silkworm, revealing its sequence, structure, and evolutionary relationships to other insect proteins.
  • ApESR16 is shown to have distinct cholesterol/lipid binding sites and possesses varying degrees of sequence identity with related proteins in both lepidopteran and non-lepidopteran insects, indicating significant evolutionary divergence.
  • Additionally, the expression of ApESR16 is influenced by the hormonal treatment of 20-hydroxyecdysone, suggesting its potential role in regulating diapause during the insect's developmental cycle.
