We present an approach to interface branching random walks with Markov chain Monte Carlo sampling and to switch seamlessly between the two. The approach is discussed in the context of auxiliary-field quantum Monte Carlo (AFQMC) but can be applied to other Monte Carlo calculations or simulations. In AFQMC, the formulation of branching random walks along imaginary-time is needed to realize a constraint to control the sign or phase problem.

Background: It has been reported that the paraesophagogastric devascularization with esophageal transection procedure, also known as the modified Sugiura procedure, was effective in the treatment of variceal bleeding. However, it was not widely accepted by other surgeons because of the high rate of rebleeding, complications, and mortality. To discover the effects of the paraesophagogastric devascularization procedure and the modified Sugiura procedure, we retrospectively analyzed the outcomes of these two procedures.

Article Synopsis
  • The study aims to compare two surgical techniques, duct-to-mucosa and end-to-side pancreaticojejunostomy, used in pancreaticoduodenectomy due to high complication rates.
  • Over six years, 240 patients were reviewed; the data showed no significant differences between the two groups in terms of demographics, intraoperative factors, or postoperative complications.
  • Both techniques resulted in similar rates of pancreatic fistula, overall complications, and hospital stays, indicating no clear advantage of one technique over the other.

We report a rare case of duodenal pseudolymphoma without any symptoms. The lesion located in front of the head of the pancreas was found accidentally during a medical examination. The findings of computed tomography and positron emission tomography-computed tomography suggested a stromal tumor or malignant lymphoma.

Aim: To investigate whether silencing Fas-associated phosphatase 1 (FAP-1) expression enhances the efficiency of chemotherapy for colon carcinoma with oxaliplatin.

Methods: Expression of FAP-1 in mRNA and protein was detected by reverse transcription polymerase chain reaction (RT-PCR) and flow cytometry. Small interfering RNA (siRNA) was designed according to the FAP-1 mRNA sequence.
