“Background Autophagy Compound Library hibernation is a strategy employed by many different mammals presumably as a means for energy conservation during periods of great thermal stress and limited food resources

[1, 2]. Ground squirrels of the genus Spermophilus are exemplary hibernators. Their winter seasons are characterized by bouts of torpor wherein body temperature may approach ambient to as low as -2°C [3, 4] and metabolic rates may be as low as 1% of the active rate [5]. These torpor bouts may last 1–3 weeks and are interrupted by brief (~20–24 h) sojourns to body temperatures and metabolic rates typical of an active animal. During the winter, golden-mantled ground squirrels (S. lateralis) are anorexic. Even when housed with free access PCI-34051 supplier to food, very few of these animals will eat for the entire ~6 month hibernation season (personal observations). Instead, animals rely on immense fat stores that were gained in an anticipatory period during late summer [2]. Hibernating animals utilize a primarily fat-based metabolism as reflected by a typical respiratory quotient (RQ) of 0.71

but employ a more carbohydrate-based metabolism (RQ = ~0.9) during the interbout-arousal [6]. As expected, the consequences of the anorexic period include a profound disuse atrophy of the gut and the physiology of this atrophy has been well described [7–9]. Although a large number of studies have used the liver as a model organ for examining the effects of hibernation on various metabolic activities such as protein synthesis, we are unaware of any studies

that have examined digestive hepatobiliary function per se during hibernation. One might expect dramatic changes in liver function Protein Tyrosine Kinase inhibitor due to the extended anorexia, metabolic fuel privation, and severe physiological conditions inherent to hibernation. Mortality rates during hibernation are high; as many as 40–70% of squirrels fail to emerge from the burrow the following spring Branched chain aminotransferase [10]. Although no data are available as to the cause of this mortality, likely explanations include a metabolic disorder or a lack of energetic supplies to withstand the extended anorexia. In maintaining laboratory colonies for other experiments, we occasionally encounter some animals that fail to hibernate (< 5% of all animals; personal observations). These animals typically lose weight quickly and die during the winter. We observed a marked difference in bile color of these animals. As a result of this observation and to characterize hepatic function during hibernation, we examined the constituents of bile in active and hibernating squirrels. Results In our experience, golden-mantled ground squirrels have proven to be very reliable hibernators in the laboratory. Indeed, we have observed hibernation at ambient temperatures of 20°C, with a variety of lighting conditions, and in the presence of free access to food. Rarely, some animals fail to hibernate (< 5% of all animals; personal observations).

Nevertheless, their extremity amputation rate (less than 5%)

was much less than ours (14%). The decision for limb amputation is more difficult than it seems. We tried at the early period of the war to save as much limbs as we could but we learned later that this cannot be achieved all the time. Sometimes, early amputation can be the best option for some patients that saves their lives. Amputation rate depends on many factors including the severity of limb injury, mechanism of injury, ischaemia time, presence of associated injuries, and disaster situations click here when treating mass causalities [17]. It is a major principle in management of war-injured patients that saving a life comes before saving a limb. Mine injuries of the lower limbs are specifically more notorious and cause internal limb damage more than what appears on the skin. The blast injury of the mine causes high pressure that is transmitted proximally between the muscles causing major damage to the tissues. We did not cover the vascular graft of the popliteal region with healthy viable tissue in two patients because of loss of all superficial DZNeP ic50 tissues. We learned that this is a major problem that can lead to limb loss even with a successful graft because the graft has to be covered by viable tissue to prevent dehydration

and infection. A rotational gastrocnemius flap if used to cover the popliteal vessels [18] could have possibly saved two secondarily amputated limbs having popliteal injuries in our series. Limitations of the study The data of the present study is a historical data of our Gulf War selleck chemical Registry. Nevertheless, we think that it is very important to share this information with others. Civilian surgeons suddenly practicing war surgery without previous experience in this field tend to repeat the same old mistakes that surgeons learned from previous wars. We could not define the exact time between vascular injury and surgery in majority of the cases. Nevertheless, we think that majority were operated within 6 hours of injury because fighting occurred very

close to our hospital and the evacuation time was less than one hour [4]. MRIP There were no extensive diagnostic radiological procedures and wounds were explored in the operating theatre as soon as possible depending mainly on the clinical findings. There have been many technical developments in the last two decade including principles of damage control surgery, use of portable ultrasound machines, and endovascular techniques. Despite that, we have recently noticed in the recent war conflicts in our region that most of these advanced techniques are not affordable except damage control surgery. Basic principles of using the least expensive surgical methods that help the maximum number of patients is still the major principle. We did not use temporary vascular shunts for peripheral vascular injuries.

Until the very end of his professional life in 1978, he used to spend time in the laboratory, mainly recording spectra of plastid components, only interrupted by a nap in the afternoon or by an occasional Beethoven symphony or by painting in the evening, while the spectrometer would record the baseline! He had a profound knowledge of classical music. Menke’s Selleck LY2874455 stay in California in 1963 resulted in a publication on the effects of desiccation on the absorption properties of chloroplasts

and algae, together with C. Stacey French and Warren L. Butler (Menke et al. 1965; also see Fork 1996) and in a lifelong attachment to chloroplast lipids. Menke seriously enjoyed his visit to Andrew A. Benson’s laboratory in San Diego. He and Benson had a mutual respect for each other. Wilhelm Menke was an extremely private person. What he wanted the outside world to know about himself he has published in his retrospective (Menke 1990) which he wrote at the invitation of Govindjee. There, he also mentioned his most important publications. Despite the fact that Menke thought mainly at the level of molecular biology—molecular structure—terms which were not in fashion in the late 1960s and early 1970s, PI3K inhibitor he was an excellent field biologist specializing in central European, mainly alpine plants. He was profoundly familiar with plants and plant

life. From his out-door observations, interesting publications arose about the plastids of the parasitic orchid Neottia nidus-avis (Menke and Wolfersdorf 1968; Menke and Schmid 1976), the plastids

in the green flowers of the orchid Aceras anthropophorum (Schmid et al. 1976) and last but not the least the plastids of the hornwort Anthoceros (Menke 1961). Menke’s outdoor observations were the source and origin for his paintings. Excellent botanical excursions led to different regions of the Alps, to Austria, but mostly to Switzerland. They were usually topped by a tour with rope and ice axe to a vegetation-less zone to which only botanists familiar with the high alpine environment were admitted. The others were supposed to botanize down in the valleys until the alpinists returned. After the death of his wife Gertrud in 1974, and especially after his retirement in the summer of 1978, Menke spent much time travelling Astemizole and painting, travelling most of the time to the Swiss Alps, where he used to spend greater parts of the summer hiking and climbing many of the overwhelming summits, frequently together with the world AZD1480 research buy famous alpine guide Ulrich Inderbinen, who died in 2004 at the age of 104 years. He was especially familiar with the Valais, the region around Zermatt and Saas Fee, and also with Engadin. His favourite spot there was Pontresina. Menke had always been interested in ancient architecture. On excursions with the authors, he never skipped a Romanesque church.

For instance, Brand B is comprised of the family

Incertae Sedis XII (96%) within the order Bacillales (100%), which is not surprising since this brand is almost entirely dominated by a single classification (Exiguobacterium) at the genus level that falls within the Liver X Receptor agonist family Incertae Sedis XII. Similar to Brand B, Brand C is also dominated by Incertae Sedix XII (45%) and Bacillales (59%), as well as Exiguobacterium (46%) at the genus level. Brand A is dominated by Clostridiaceae (67%) at the Cell Cycle inhibitor family level, which falls within the order Clostridiales noted in Brand A at 67% abundance. Clostridiaceae dominates Brand A at the genus level with 68%, which falls within the Clostridiaceae family. The diversity and uniqueness of Brand A cheese is partially explained by a replicate within Brand A, replicate Brand A_rep1, that

appears to have more diversity at the class level than the other 3 replicates, with the presence of Alphaproteobacteria, Actinobacteria, and Betaproteobacteria, of which only Alphaproteobacteria is shared by Brand A_rep3 in very low abundance. This diversity is evident at the genus level as well (Figures 1 and 2), with Brand A_rep1 containing 4 operational taxonomic units (OTUs) not found in any other Brand A replicates, nor in any samples from the other cheese brands, using a 95% identity threshold for clustering sequences. In addition, Brand A_rep1 contains 13 OTUs total that occurred at a ≥ 1% abundance in the sample at the genus level, while the other Brand A replicates as well as all replicates from the other cheese brands contain no more than 7 OTUs per sample.

Diversity analysis using operational taxonomic units Rarefaction curves of all enriched cheese samples (Figure 3), also support the observation that Brand A samples supported the greatest diversity among the three cheeses. The greater diversity of Brand A cheese sample Brand A_rep1 is displayed, rising dramatically above all other samples. This is confirmed with the UniFrac metric, which shows the replicate samples of each brand distinctly clustered together by brand except for Brand A_rep1. Brand C replicates cluster together rather tightly, more so than the Brand B replicates. Figure 3 Rarefaction curves of OTUs in all 4 replicates of each cheese brand.

Replicates within each cheese type clustered as expected at the genus level except for the Brand A_ rep1 (Figure 2).

Approaches, methods and tools, such as ecosystem-based adaptation to climate change, communication and education strategies, and experience with an international community of practice, representing components of sustainability science, are considered

in various papers. Overview of papers in this Special Issue Following is a brief synopsis of the papers in this Special Issue. The aim is not to summarize the content of each paper but to demonstrate that individually and collectively the papers make an important contribution to our understanding of sustainability challenges and strategies for building resilience in small island communities and states. Understanding and managing global change pressures and processes MCC950 in vitro in SIDS and other small islands The paper by Hay (Small islands: coastal systems, global change and sustainability) is a significant expansion on the invited

keynote presentation in the small islands session of the 2011 conference. The paper highlights important points made in two recent studies. The first is that, while SIDS and other small islands have long been represented selleck inhibitor as sites of vulnerability, communities on many such islands have in fact survived for millennia. Only over the past few centuries and, more particularly, in recent decades, have the processes of colonialism, development and globalisation caused lower resilience and greater exposure, thereby increasing vulnerability. Secondly, globalisation is nothing new for many SIDS and other small islands. Generally they have had a long history of being reshaped by shifts in international economic and political relations, and the spread of technological innovation. It is argued that the more recent global pressures on SIDS and other small islands are characterised by time-space compression—they

seem to be occurring more rapidly and with wider PD184352 (CI-1040) reach. In order to fully understand and respond to these and other findings on how global change has, does and will affect SIDS and other small islands, the paper clarifies the concepts of exposure, risk, vulnerability, resilience and sustainability and suggests a suite of management Selleckchem PARP inhibitor interventions that will help reduce the vulnerability and enhance the resilience of small islands to global and other changes. Thus the paper covers the three key aspects of understanding and managing global change in small islands (Fig. 1), and provides the context for the other papers in this Special Issue. The paper by Forbes and co-authors (Physical basis of adaptation on tropical small islands) considers the global and island-specific physical context in which island communities are exposed to the impacts of climate change and natural hazards.
