Article Abstract
A multi-patch HIV/AIDS model with heterosexual transmission is formulated to investigate the impact of population migration on the spread of HIV/AIDS. We derive the basic reproduction number and prove that if , the disease-free equilibrium is globally asymptotically stable. If and certain conditions are satisfied, the endemic equilibrium is globally asymptotically stable. We apply the model to two patches and conduct numerical simulations. If HIV/AIDS becomes extinct in each patch when two patches are isolated, the disease remains extinct in two patches when the population migration occurs; if HIV/AIDS spreads in each patch when two patches are isolated, the disease remains persistent in two patches when the population migration occurs; if the disease disappears in one patch and spreads in the other patch when they are isolated, the disease can spread or disappear in two patches if migration rates of individuals are suitably chosen.

Purpose: Ovarian cancer ranks as a gynecological malignancy with poor prognosis, specifically if detected late. Primary treatment includes cytoreductive surgery and adjuvant chemotherapy with curative intent. Local anesthetics (LA) administered in the perioperative period may potentially impact patient outcome by several mechanisms.

The Tone River in Japan represents one of the southern limit distributions of chum salmon (Oncorhynchus keta) on the western side of the North Pacific, but the number of adult chum salmon observed here has declined dramatically since 2013 and reached zero in 2024. The factors behind the recent decline of the chum salmon population in the Tone River were investigated by using ocean reanalysis data and a 20-year particle-tracking simulation. Virtual chum salmon fry were released at the mouth of the Tone River in spring each year with six different swimming strategies to evaluate the effects of ocean currents on the population growth rate of salmon.

For thousands of years, parasitic infections have represented a constant challenge to human health. Despite constant progress in science and medicine, the challenge has remained mostly unchanged over the years, partly due to the vast complexity of the host-parasite-environment relationships. Over the last century, our approaches to these challenges have evolved through considerable advances in science and technology, offering new and better solutions.

Wellbeing is a widely used concept yet lacks a universal definition and standardized measurement. Migrants, especially those forcibly displaced, face challenges that impact their quality of life and wellbeing. To understand how the wellbeing of people who migrate from low/middle-income countries to middle/high-income countries has been conceptualized, defined, and measured.
