In order to analyze the adaptation potential of tomato shoots to a sudden increase in Cd concentration, tomato plants （Solanum lycopersicum L. var. Ailsa Craig） were exposed under controlled environmental conditions to a high dose of this heavy metal （250 μm CdCl2） in nutrient solution for 7 and 14d. Both root and shoot growth was completely inhibited but all plants remained alive until the end of the treatment. Cell viability remained unaffected but the activity of the mitochondrial alternative pathway was stimulated by Cd stress at the expense of the cytochrome pathway. Cadmium concentration was higher in roots than in shoots and a decrease in the rate of net Cd translocation was noticed during the second week of stress. Cadmium decreased both leaf conductance （gl） and chlorophyll concentration. However, the effect on net CO2 assimilation remained limited and soluble sugars accumulated in leaves. Photochemical efficiency of PSII （FvlFm） was not affected despite a decrease in the number of reaction centers and an inhibition of electron transfer to acceptors of PSII. It is concluded that tomato shoot may sustain short term exposure to high doses of cadmium despite growth inhibition. This property implies several physiological strategies linked to both avoidance and tolerance mechanisms.

Recent reports suggest that aging is not solely a physiological process in living beings;instead, it should be considered a pathological process or disease(Amorim et al., 2022). Consequently, this process involves a wide range of factors, spanning from genetic to environmental factors, and even includes the gut microbiome(GM)(Mayer et al., 2022). All these processes coincide at some point in the inflammatory process, oxidative stress, and apoptosis, at different degrees in various organs and systems that constitute a living organism(Mayer et al., 2022;AguilarHernández et al., 2023).

Part one:The earlier years I am christine, Ray’s younger sister. The last time that I was in this auditorium (Kendal re-tirement community), about 7 years ago, Ray was giving a wonderful talk on 'CHInA'. Ray was always very proud of his Chinese heritage, especially since he was born and raised in China where he lived twenty years.

In Latin America, default assumptions and borrowed templates and methodologies are often used in energy modeling, resulting in models that might not represent their cultural context and leading to policies awkwardly fit to local practices. Policy-driving low-income housing studies in Mexico, for example, activated both heating and cooling in energy models even though less than 5% of the homes in the country have heating systems. This paper illustrates the importance of modeling local sociocultural habits and practices, and how this can affect design outcomes. Here, we modeled low-income housing representative of typical residences in two desert climates-Hermosillo, Mexico, and Copiapo, Chile-using EnergyPlus. Settings representing local practices in each region were tested against default values, including occupancy settings, regional construction systems, and importantly, HVAC settings related to partial conditioning. Their impacts were measured via variation in energy use, comfort conditions, and the payback period of design upgrades. Results demonstrated how certain assumptions can have a high “design significance”, a term we propose for inputs that completely change optimal design decisions, as well as the importance of considering thermal comfort in such decisions. Including partial conditioning, for example, resulted in at least double the payback period and discomfort degrees for design upgrades in 16 of 24 instances.

To the Editor:Biliary stricture formation at the bilioenteric anastomosis is an infrequent complication(2%-3%)after pancreaticoduodenectomy;the average presentation is within 13-14 months(range from 1 month to 9 years)after surgery[1,2].While the etiology is unknown,development of biliary stricture has shown to be more likely if a bile leak occurs in the postoperative period[3,4]and with younger patients[5].

This article explores the strengths of ethnography as a methodology for exploring the complex social landscape of the contemporary Intemet. The article outlines the historical development of the Intemet, from Web 1.0 to a participatory Web 2.0 embedded within everyday life and ultimately to the prospect of an autonomous Internet of Things. The benefits of an ethnographic approach for understanding such developments in depth and examining taken-for-granted assumptions are outlined alongside an account of some of the challenges that digital technologies pose for an ethnographic methodology. Amongst these challenges are the difficulties inherent in mapping out a field site that effectively captures the complexity of online/offline connections and of developing a sufficient degree of immersion and co-presence for a rich understanding to be attained. Finally, the challenges offered by the emergence of mobile Internet, algorithmic filtering of information and unpredictable flows of data are explored. It is suggested that the ethnographer of the Internet can usefully position their task as being to explore a socially constructed yet technologically mediated landscape, immersing themselves in it, interrogating how others experience it and mapping the ways in which it becomes meaningful to those who navigate its complexities.
