The role of mitochondria in cell metabolism and survival is controlled by calcium signals that are commonly transmitted at the close associations between endoplasmic reticulum (ER). However, physical linkage ER-mitochondria interface its relevance for function remains elusive. We show electron tomography ER adjoined tethers approximately 10 nm smooth 25 rough ER. Limited proteolysis separates from mitochondria, whereas expression a short "synthetic linker" (<5 nm) leads to tightening...

Mitochondria are dynamic organelles in cells. The control of mitochondrial motility by signaling mechanisms and the significance rapid changes remains elusive. In cardiac myoblasts, mitochondria were observed close to microtubular array displayed both short- long-range movements along microtubules. By clamping cytoplasmic [Ca2+] ([Ca2+]c) at various levels, was found be regulated Ca2+ physiological range. Maximal movement obtained resting [Ca2+]c with complete arrest 1–2 μM. Movement fully...

This opinion piece contends that tourism's expanding engagement with climate change, as it is currently unfolding, not necessarily conducive to the interests of tourism sustainability. Inherent unpredictability, long-term timeframes, lack directly tangible consequences or clearly identifiable villains, issues credibility and vested cost implications in an era chronic economic uncertainty all combine increase likelihood unsuccessful change policies strategies. Additional complications arise...

Contact sites of endoplasmic reticulum (ER) and mitochondria locally convey calcium signals between the IP3 receptors (IP3R) mitochondrial uniporter, are central to cell survival. It remains unclear whether IP3Rs also have a structural role in contact formation different IP3R isoforms redundant functions. Using an IP3R-deficient model rescued with each three array super-resolution ultrastructural approaches we demonstrate that required for maintaining ER-mitochondrial contacts. This is...

Very little is known about the characteristics of overnight ecolodge patrons. This study reports on results a questionnaire that was completed by 1,180 individuals who had stayed at least one night in either two well-known ecolodges Lamington National Park, Australia. A cluster analysis 37 items pertaining to ecotourism behavior revealed three distinct groups. “Harder” ecotourists reflect high level environmental commitment and affinities with wilderness-type experiences, while “softer” are...

This study examines the relationships of exposure and attention to various news media, including Internet, with information learned about issue positions candidates George Bush John Kerry, interest in 2004 election campaign, intention vote among a random sample adult residents Indiana who were interviewed by telephone October 2004. The results are compared our previous studies 1988, 1992, 1996, 2000 U.S. presidential elections. In general, suggest that television news, televised debates, now...

Using resolution-based dialectics, sustainable tourism is contextualized as an evolving synthesis arising from the need for capitalist-based mass thesis and ethics-based alternative antithesis to amalgamate because of internal contradictions that limit their contribution development. That this skewed accounted by four unrealistic unrealized expectations, functional incompleteness, growth implications success, nonreciprocal accommodation. Mass tourism, faced with a prime contradiction...

Engaging the neglected intersection between dark tourism, visitor postexperience and geopolitics, this research reports findings from a survey of 1,082 domestic visitors to Lushun Prison Museum in Dalian, China, Japanese-era incarceration punishment site that projects hegemonic anti-Japanese social representations. Most respondents reported strong emotional reactions elevated patriotism along with worsened attitudes toward Japan, Japanese products and, lesser degree, people, suggesting...

This article analyzed a living cultural heritage destination’s adaptive resilience from the perspective of social-ecological systems (SES). The aim was to test SES framework at Hoi An Ancient Town, World Heritage Site in central Viet Nam by (1) delineating renewal cycle historical context destination development; (2) examining community spatio-cultural changes induced mass tourism; and (3) identifying characteristics tourism via control mechanisms panarchy’s cross-scale interactions....

Periodic assessment of the 'state play' in research outputs is an essential process for gauging academic progress and latent trends within a field study. Bibliometric analysis 839 sustainable tourism-related papers over thirty-year period (1987–2017), extracted from selection top ranked tourism journals confirmed lack reticulation integration among individual contributions, part due to exponential increase output, but parallel evidence subdomain maturation. This includes reduced emphasis on...
