Background: Although the technique of single-incision laparoscopic cholecystectomy (SILC) has improved remarkably, problems such as limited exposure and instrument collision persist. We describe a new SILC technique that uses a set of specially-designed needle instruments.
Methods: Fifty-six patients with benign gallbladder disease underwent SILC using the newly-designed needle assembly instruments (NAIs). The NAIs comprise an needle assembly exposing hook for operative field exposure and an needle assembly electrocoagulation hook for dissection. During the operation, the NAIs were assembled and disassembled before and after gallbladder removal within the abdominal cavity. The operative efficacy and postoperative complications of this procedure were evaluated.
Results: SILC was completed successfully in 52 cases, and four cases (7.14%) required an additional trocar. There were no conversions to open surgery. The mean operative time was 48.2 ± 21.8 min, and the mean operative bleeding volume was 10.5 ± 12.5 mL. Minor postoperative complications occurred in 3 cases, including 2 cases of localized fluid accumulation in the abdominal cavity and 1 case of pulmonary infection, and all of them recovered after conservative treatment. There was no occurrence of bile leak, abdominal bleeding, bile duct injury and incisional hernia. The medical cost of each case was saved by approximately $200. The abdominal scars produced by the needle instruments were negligible.
Conclusion: NAIs can make SILC safer, more convenient, and less expensive.

The 1990 resolution by the UN General Assembly committed member states to provide health-care equity for people in prison, who are included in the global goals to control HIV and eliminate hepatitis C virus (HCV) by 2030. WHO has set ambitious HCV elimination targets by including people who inject drugs (PWID), yet has not prioritised PWID who are incarcerated, a substantial population who have or are at risk for HCV infection. Human rights principles of health-care equity stipulate that "prisoners should enjoy the same standards of health care that are available in the community, without discrimination on the grounds of their legal status".

Spermatogenesis is a key process for the sexual reproduction species. In lepidopteran insects, spermatogenesis produces two different types of sperms, in which eupyrene sperm carry genomic DNA and fertilize eggs, whereas apyrene sperm are necessary for eupyrene sperm to enter eggs. However, functional genetic studies of spermatogenesis in Plutella xylostella remain a longstanding puzzle even though the phenomenon in lepidoptera has been widely documented more than a century.

Background: To investigate microbial characteristics across multibody sites from chronic pancreatitis (CP), through pancreatic benign tumors, to pancreatic ductal adenocarcinoma (PDAC) at different stages.
Methods: 16S ribosomal RNA (rRNA) amplicon sequencing was conducted on saliva, duodenal fluid, and pancreatic tissue obtained via endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of patients with CP, pancreatic benign tumors, PDAC in stage I/II, III, and IV. The neutral community model (NCM) assessed the microbial assembly contribution and MaAslin2 identified the differential microbes.
Crystallization Control of Anionic Thiacalixarenes on Silicon Surface Coated with Cationic Poly(ethyleneimine).

Surface modification of solid substrates with organic molecules and polyelectrolytes is a promising strategy toward advanced soft materials due to the control of molecular arrangement and supramolecular organization; however, understanding the nature of interactions within the assembly is challenging. Here a facile approach to the control of the architecture of calixarene macrocycles on soft surfaces is presented through the interplay of weak interactions involving a solid silicon substrate, a cationic polyelectrolyte layer, and anionic sulfonatothiacalix[4]arene (STCA). Topological analysis of atomic force microscopy (AFM) images of STCA on silicon, as well as silicon wafers modified with neutral polyethylenimine (PEI) and cationic PEI-H, indicates different surface morphology and assembly behavior of STCA on such substrates.
