We describe a new species of the genus Lycodon based on an adult male specimen from Thanh Hoa Province, Vietnam. Lycodon namdongensis sp. nov. is differentiated from its congeners by a combination of the following characters: dorsal scales in 17-17-15 rows, all smooth; supralabials 8; infralabials 10; one large loreal on each side, separated from the eye; cloacal single; ventral scales 218 (plus two preventral scales); subcaudals 85, paired; a total length of 723 mm; tail / total length ratio 0.205; dorsal head pattern whitish grey; dorsal surface of body with 23 narrow greyish cream bands; dorsal surface of tail with 14 cream bands; ventral surface of body mostly cream with a few small dark spots posteriorly; ventral surface of tail dark grey. Based on molecular comparisons, Lycodon namdongensis sp. nov. is recovered as a sister species to L. futsingensis with strong support values from all three analyses. The new species is at least 6.5% genetically divergent from other species within this clade as shown by a fragment of more than 1000 pbs of the mitochondrial cytochrome b. This discovery increases the number of Lycodon species known from Vietnam to 15.
Data sharing holds promise to accelerate innovative discoveries through artificial intelligence (AI) and traditional analytics. However, it remains unclear whether these prospects translate into tangible benefits in improving health care and scientific progress. In this cross-sectional study, we investigate current data reuse practices and explore ways to enhance the use of existing data in clinical research, focusing on low- and middle-income countries.
A previously healthy woman, 5 weeks pregnant, was admitted to the intensive care unit in critical condition for septic shock and acute respiratory distress syndrome due to methicillin-resistant (MRSA) after being infected with Influenza for 3 days. The patient in this case suffered from severe sequelae due to necrotizing pneumonia and later died on the 20th day after admission. We would like to remind clinicians to be aware of this rare but serious diagnosis.
Sepsis is a severe, life-threatening illness caused when the immune system responds inappropriately to infections, causing organ deterioration and negatively affecting the systems inside the body, one of which is the coagulation system. Most hematologic changes in red blood cells (RBCs) are non-antibody-mediated hemolytic anemia (NAHA). Autoimmune hemolytic anemia (AIHA) is a rare condition, challenging in diagnosis, requiring prompt recognition and management.
Background: We assessed the morphologies of meiotic spindles in oocytes that failed to fertilize following intracytoplasmic sperm injection (ICSI) and identified factors contributing to failed fertilization.
Methods: A total of 225 unfertilized oocytes were collected after ICSI. Oocytes were fixed and stained for tubulin and chromosomes.
BACKGROUND Esophageal invasion in hypopharyngeal cancer is an uncommon lesion and has a poor prognosis. Total pharyngo-laryngo-esophagectomy is the most effective treatment option. Reconstruction of the gastrointestinal tract in the same period of surgery is required.
