Opis:
The stages of human life and the corresponding physiological changes have been described in many ways since ancient times. Although old age was characterized by physical and mental weakening (senility), it was portrayed as an age of wisdom which contrasted youth dominated by passions. Vincent of Beauvais devoted a few extensive chapters of Speculum naturale to the last stage of life and cited works of Cicero, Aristotle, Horace, Virgil, St. Jerome, St. Ambrose, Avicenna, Isidore of Seville, which gave him a place in the intellectual tradition of his era. According to him, the advantages of old age were moderation in pleasures, lower libido, wisdom, maturity of advice, common sense and reconciliation to death. The negative aspects of senility were diseases, discouragement and drowsiness. The physical weakness of the body affected the stability of mind. Vincent recognized old age as a natural period in human life and characterized it from the philosophical and medical points of view. He chose those pieces of writings which he considered important and representing different aspects of old age. He advised on nutrition, strengthening of the body and mental energy. Vincent emphasized that old age should be considered as fate. Therefore, there is no reason to fall in despair and wallow in hopelessness, but prepare for death through a wise life.

Opis:
e adaptability of plants to drought not only includes their ability to resist drought stress, but also their ability to recover aer stress is relieved. In this study, a weighting method was used to control the soil water content to produce a soil water stress gradient. e effects of drought and rewatering on the changes in osmotic adjustment substance content, antioxidant enzyme activity, and photosynthetic characteristics of potted Dicranostigma henanensis seedlings were measured on Day 28 aer the imposition of watering treatments and Day 7 aer rewatering. During the drought stress process, the relative electrical conductivity, thiobarbituric acid, water use efficiency, and proline content displayed a continuously increasing trend. Further, the net photosynthetic rate, stomatal conductance, and transpiration rate constantly decreased, while the chlorophyll content first increased and then decreased. Aer rehydration, superoxide dismutase (EC 1.15.1.1) activity and photosynthetic parameters quickly recovered to the CK level (soil moisture is 75%–80% of the maximum water holding capacity in the field), indicating that D. henanensis plants have a strong ability to repair the damage caused by drought stress. In particular, the photosynthetic machinery may have sophisticated regulation and repair mechanisms, which may be associated with its stable photosystem. Collectively, our findings demonstrate that the D. henanensis plant has a strong ability to adapt to arid environments, and therefore could be an excellent ornamental flower for landscaping in arid and semiarid areas.
