Prey-predator systems in patchy environment, connected through dispersal between patches is a very common phenomenon observed in nature, which have a significant impact in ecology, species persistence and extinction, etc. In the present paper, we consider a two patch prey-predator system where the patches are connected through dispersal between preys populations only. We consider positive density dependence growth for preys population. In addition, we consider the time scale difference (different life span) between preys and predator populations. From our study, we can conclude that dispersal can save both the populations from extinction, when in a single patch initial preys density is lower the Allee threshold. Also, time difference can increase the basin of attraction of the coexistence equilibrium of our two-patch model. Time scale difference also can help to reach the steady state faster than the without time scale difference, and it also causes the amplitude death when populations are in limit cycle oscillation. We also analyze our model by considering the time delay in dispersal dynamics, and we show that delay induced dispersal can stabilize the system and cause the amplitude death when individual populations are in the limit cycle, without dispersal. In addition, dispersal in non-identical patches can stabilize at its interior equilibrium even if the environment is harsh for both the populations in both the individual patches.

Objectives: Pediatric neurocritical care (PNCC) patients experience high rates of morbidity, but comprehensive follow-up is not universal. We sought to identify predictors of functional decline in these children to guide future resource allocation.
Patients And Methods: We conducted a prospective observational study in a quaternary children's hospital pediatric intensive care unit (PICU) from July 2023 to December 2023.

Pressures on honey bee health have substantially increased both colony mortality and beekeepers' costs for hive management across Europe. Although technological advances could offer cost-effective solutions to these challenges, there is little research into the incentives and barriers to technological adoption by beekeepers in Europe. Our study is the first to investigate beekeepers' willingness to adopt the Bee Health Card, a molecular diagnostic tool developed within the PoshBee EU project which can rapidly assess bee health by monitoring molecular changes in bees.

A deviated nasal septum leads to congestion and headaches. Surgery is the primary treatment, requiring careful postoperative septum positioning to prevent bleeding and hematoma. The study compared this method with nasal packing and traditional nasal septum suturing regarding surgical time, patient pain, nasal obstruction, and bleeding after septoplasty.

Background: The therapeutic targeting of the intestinal microbiota has gained increasing attention as a promising avenue for addressing mood disorders. This study aimed to assess the potential effect of supplementing standard pharmacological treatment with the probiotic kefir in patients with Major Depressive Disorder (MDD).
Methods: Thirty-eight female participants diagnosed with moderate MDD by the Hamilton Rating Scale for Depression (HAM-D) were selected to receive the probiotic kefir in conjunction with antidepressant therapy for 12 weeks.
