[Short-term outcomes of mechanical and hand-sewn laparoscopic one-anastomosis mini-gastric bypass].

Objective: To evaluate the short-term outcomes of mechanical and hand-sewn laparoscopic one-anastomosis mini-gastric bypass.

Material And Methods: There were 233 patients who underwent laparoscopic one-anastomosis mini-gastric bypass. Short-term results were analyzed in groups of mechanical (the first group, =108) and hand-sewn (the second group, =125) gastrojejunostomy.

Lysocin E Targeting Menaquinone in the Membrane of Mycobacterium tuberculosis Is a Promising Lead Compound for Antituberculosis Drugs.

Tuberculosis remains a public health crisis and a health security threat. There is an urgent need to develop new antituberculosis drugs with novel modes of action to cure drug-resistant tuberculosis and shorten the chemotherapy period by sterilizing tissues infected with dormant bacteria. Lysocin E is an antibiotic that showed antibacterial activity against Staphylococcus aureus by binding to its menaquinone (commonly known as vitamin K).

Extracellular DNA of slow growers of mycobacteria and its contribution to biofilm formation and drug tolerance.

DNA is basically an intracellular molecule that stores genetic information and carries instructions for growth and reproduction in all cellular organisms. However, in some bacteria, DNA has additional roles outside the cells as extracellular DNA (eDNA), which is an essential component of biofilm formation and hence antibiotic tolerance. Mycobacteria include life-threating human pathogens, most of which are slow growers.

Higher genome mutation rates of Beijing lineage of Mycobacterium tuberculosis during human infection.

Mycobacterium tuberculosis (Mtb) strains of Beijing lineage have caused great concern because of their rapid emergence of drug resistance and worldwide spread. DNA mutation rates that reflect evolutional adaptation to host responses and the appearance of drug resistance have not been elucidated in human-infected Beijing strains. We tracked and obtained an original Mtb isolate of Beijing lineage from the 1999 tuberculosis outbreak in Japan, as well as five other isolates that spread in humans, and two isolates from the patient caused recurrence.

Modeling of high-fluence irradiation of amorphous Si and crystalline Al by linearly focused Ar ions.

Long time ion irradiation of surfaces under tilted incidence causes formation of regular nanostructures known as surface ripples. The nature of mechanisms leading to ripples is still not clear, this is why computational methods can shed the light on such a complex phenomenon and help to understand which surface processes are mainly responsible for it. In this work, we analyse the surface response of two materials, a semiconductor (silicon) and a metal (aluminium) under irradiation with the 250 eV and 1000 eV Ar ions focused at 70° from the normal to the surface.
