Predicting maximum Lifespan Limits at mean menopausal Age

Journal of mathematical Research with Applications 2025年第1期 133-142页

作者： m.sUmATHI s.ANTONY CARLA Department of mathematics N.M.S.S.Vellaichamy Nadar College Research scholar (Part-time) Madurai Kamaraj University

The age at which a woman enters natural menopause has also been associated to death from any cause. menopause is a natural component of aging that happens between the ages of 45 and 55, with the average menopausal age being 51. Previous research has revealed the age at which women reach menopause, but there is no evidence to support the link between menopause and longevity. We made a study in assessing the limits of maximum lifespan at menopausal age in our previous article. In this paper, we aim to predict the maximum lifespan of women at mean menopausal age.

Emerging role of A-kinase anchoring protein 5 signaling in reward circuit function

There is a strong evidence supporting the hypothesis of synaptic dysfunction as a major contributor to neural circuit and network disruption underlying emotional and mood dysregulation in psychiatric disorders(simmons et al.,2024).Diverse sets of distinct molecular signaling pathways converge on the synapse to regulate synaptogenesis,synaptic function,and synaptic plasticity in brain regions and circuits through complex interactions organized by numerous multivalent protein scaffolds,including the family of proteins known as A-kinase anchoring proteins(AKAPs).

Variation in metabolic enzymatic activity in white muscle and liver of blue tilapia,Oreochromis aureus,in response to long-term thermal acclimatization

引用

Chinese Journal of Oceanology and Limnology 2015年第3期33卷 696-704页

作者： elsayed m.YOUNIs Zoology Department College of Science King Saud University

The effects of rearing temperature on white muscle and hepatic phosphofructokinase （PFK）, pyruvate kinase （PK）, lactate dehydrogenase （LDH）, aspartate aminotransferase （AsT） and alanine aminotransferase （ALT） were examined in fingerlings of blue tilapia, Oreochromis aureus. The experiment was conducted for 14 weeks at temperatures of 18, 22, 26, 30, and 34℃. The activity of the glycolytic enzymes PFK, PK, and LDH in white muscle increased significantly with increase in water temperature. A reverse trend was observed for these enzymes in the liver, except for LDH, which behaved in the same manner as in white muscle. Cytosolic AsT and ALT activity increased in both white muscle and liver in response to warm thermal acclimatization, while a reduction in mitochondrial AsT and ALT activity was noticed at high temperatures in comparison with those at a lower temperature.

Interplay between strong Allee effect, harvesting and hydra effect of a single population discrete-time system

引用

International Journal of Biomathematics 2016年第1期9卷 65-89页

作者： Debaldev Jana elsayed m. elsayed Ecological modelling LaboratoryDepartment of Zoology Visva-Bharati University Santiniketan 731235 India mathematics DepartmentFaculty of science King Abdulaziz UniversityP.

The dynamics of a single population with non-overlapping generations can be described deterministically by a scalar difference equation in this study. A discrete-time Beverton- Holt stock recruitment model with Allee effect, harvesting and hydra effect is proposed and studied. model with strong Allee effect results from incorporating mate limitation in the Beverton-Holt model. We show that these simple models exhibit some interesting （and sometimes unexpected） phenomena such as the hydra effect, sudden collapses and essential extinction. Along with this, harvesting is a socio-economie issue to continue any system generation after generation. Different dynamical behaviors for these situations have been illustrated numerically also. The biological implications of our analytical and numerical findings are discussed critically.
