The physiology of the plants has come to be a formidable challenge. Despite best efforts, the mysteries remain, most of the processes identified cannot be played in vitro, and to date it cannot be said that knowledge about the complex biochemical processes of the plant is understood properly. The need to produce food is an emergency in the world, so any knowledge that will allow us to advance in this sense is important. Our discovery about the intrinsic property of melanin transform light energy into chemical energy by means of the dissociation of the molecule of water, such as chlorophyll in plants, represents a turning point in relation to the chemical reaction so far considered the most important in the world: photosynthesis.

端粒在基因组稳定、细胞核结构以及减数分裂中染色体配对中发挥关键作用。细胞每分裂一次,端粒会缩短,缩短的端粒可能再延长或不延长,这取决于细胞内是否存在一种专用酶-端粒酶。由于人体的多数体细胞并不表达端粒酶,因此发育和衰老过程中端粒必然缩短。在生理条件下,端粒缩短与延长的细胞增殖相矛盾,因此端粒长度决定了细胞的增殖潜能,并作为细胞无限生长的预防机制。相反,在细胞增殖检查点受破坏的细胞中,缩短的端粒可导致染色体融合并启动断裂-融合-桥周期,这极大地促发了基因组不稳定。在体外研究中,转化细胞中由于端粒严重缩短造成的基因组高度不稳定,在这种细胞种蓄积了有害的遗传改变,从而导致细胞最终死亡(危象)。同时,随机的遗传或拟遗传学改变可使细胞获得端粒维持机制(以及其它肿瘤表型),从而成为永生细胞。在体内研究中,尽管在早期肿瘤细胞中发现端粒缩短和其它形式的端粒功能障碍可能使基因组不稳定,但端粒功能障碍对于人类肿瘤表型的直接作用有待进一步研究。

Change in environmental conditions with altitudinal gradients induces morpho-anatomical variations in plants that have been poorly documented in intertropical regions. Five species with three life forms, cryptophyte(Alchemilla procumbens, Geranium seemannii), hemicryptophyte(Acaena elongata, Lupinus montanus), and phanerophyte(Symphoricarpos microphyllus), distributed along an altitudinal gradient in the Sierra Nevada of central Mexico, were studied. The aims were to identify and evaluate their morpho-anatomical modifications under the hypothesis that the sizes of individuals and of their wood and leaf cell types decrease as elevation increases. Three individuals per species per site were collected at seven locations along the altitudinal gradient(2949-3952 m). Their morpho-anatomical characters were analyzed through multiple regression analyses. Elevation was the variable that best explained anatomical changes in the leaf and wood ofthe five species. Canopy density and potassium content in the soil also contributed to explain the variation in anatomical variables along the gradient. As elevation increased a bimodal pattern was observed in various anatomical characters as in the leaf width of A. elongata, A. procumbens and G. seemannii and in the vessel diameter of A. procumbens, G. seemannii, and L. montanus. Other features as the vessel diameter of A. elongata, the fiber length of S. microphyllus, and the ray width of A. elongata increased as the elevation increased. Anatomical traits have a tendency to decrease in size but just toward the end of the gradient, which is probably related to changes in canopy density. The plant response to the altitudinal gradient is more focused on anatomical adaptations than morphological variation; it is also species dependent.

Social transformations have been changed in thinking and observable current religious institutions in contemporary architectural manifestations. Likewise, observed these changes in religious buildings of the past, they were current and contemporary in its own time, which has allowed them to remain in force in its architectural spatiality and its urban relationships, serving as the historical bridge 1;hat allows analyzing the contemporary perspective in Mexico and particularly in Yucatan. The goal of this paper is to carry out a contemporary look to the interior and exterior of the temples in Yucatan colonial architecture to establish the process of change and permanence of spatiality and volumes that have allowed liturgy procedures as well as the way of approach to the sacredness of the Catholic communities from the colonial period to the present day. On the other hand, interest to establish, in particular, as the colonials religious buildings have been maintained in force and have appreciated for religious service to continue and in some cases, as they have given other kinds of services while maintaining its primordial spatiality.
