Abstract

Background: The SARS-CoV-2 pandemic is still ongoing and a major challenge for health care services worldwide. In the first WSES COVID-19 emergency surgery survey, a strong negative impact on emergency surgery (ES) had been described already early in the pandemic situation. However, the knowledge is limited about current effects of the pandemic on patient flow through emergency rooms, daily routine and decision making in ES as well as their changes over time during the last two pandemic years. This second WSES COVID-19 emergency surgery survey investigates the impact of the SARS-CoV-2 pandemic on ES during the course of the pandemic. Methods: A web survey had been distributed to medical specialists in ES during a four-week period from January 2022, investigating the impact of the pandemic on patients and septic diseases both requiring ES, structural problems due to the pandemic and time-to-intervention in ES routine. Results: 367 collaborators from 59 countries responded to the survey. The majority indicated that the pandemic still significantly impacts on treatment and outcome of surgical emergency patients (83.1% and 78.5%, respectively). As reasons, the collaborators reported decreased case load in ES (44.7%), but patients presenting with more prolonged and severe diseases, especially concerning perforated appendicitis (62.1%) and diverticulitis (57.5%). Otherwise, approximately 50% of the participants still observe a delay in time-to-intervention in ES compared with the situation before the pandemic. Relevant causes leading to enlarged time-to-intervention in ES during the pandemic are persistent problems with in-hospital logistics, lacks in medical staff as well as operating room and intensive care capacities during the pandemic. This leads not only to the need for triage or transferring of ES patients to other hospitals, reported by 64.0% and 48.8% of the collaborators, respectively, but also to paradigm shifts in treatment modalities to non-operative approach

Abstract

The genetic formation of Central and South Asian populations has been unclear because of an absence of ancient DNA. To address this gap, we generated genome-wide data from 362 ancient individuals, including the first from eastern Iran, Turan (Uzbekistan, Turkmenistan, and Tajikistan), Bronze Age Kazakhstan, and South Asia. Our data reveal a complex set of genetic sources that ultimately combined to form the ancestry of South Asians today. We document a southward spread of genetic ancestry from the Eurasian Steppe, correlating with the archaeologically known expansion of pastoralist sites from the Steppe to Turan in the Middle Bronze Age (2300-1500 BCE). These Steppe communities mixed genetically with peoples of the Bactria Margiana Archaeological Complex (BMAC) whom they encountered in Turan (primarily descendants of earlier agriculturalists of Iran), but there is no evidence that the main BMAC population contributed genetically to later South Asians. Instead, Steppe communities integrated farther south throughout the 2nd millennium BCE, and we show that they mixed with a more southern population that we document at multiple sites as outlier individuals exhibiting a distinctive mixture of ancestry related to Iranian agriculturalists and South Asian hunter-gathers. We call this group Indus Periphery because they were found at sites in cultural contact with the Indus Valley Civilization (IVC) and along its northern fringe, and also because they were genetically similar to post-IVC groups in the Swat Valley of Pakistan. By co-analyzing ancient DNA and genomic data from diverse present-day South Asians, we show that Indus Periphery-related people are the single most important source of ancestry in South Asia —} consistent with the idea that the Indus Periphery individuals are providing us with the first direct look at the ancestry of peoples of the IVC {— and we develop a model for the formation of present-day South Asians in terms of the temporally and geographically proximate sources of Indus Periphery-related, Steppe, and local South Asian hunter-gatherer-related ancestry. Our results show how ancestry from the Steppe genetically linked Europe and South Asia in the Bronze Age, and identifies the populations that almost certainly were responsible for spreading Indo-European languages across much of Eurasia.

Abstract

The origins of the Bronze Age Minoan and Mycenaean cultures have puzzled archaeologists for more than a century. We have assembled genome-wide data from 19 ancient individuals, including Minoans from Crete, Mycenaeans from mainland Greece, and their eastern neighbours from southwestern Anatolia. Here we show that Minoans and Mycenaeans were genetically similar, having at least three-quarters of their ancestry from the first Neolithic farmers of western Anatolia and the Aegean, and most of the remainder from ancient populations related to those of the Caucasus and Iran. However, the Mycenaeans differed from Minoans in deriving additional ancestry from an ultimate source related to the hunter-gatherers of eastern Europe and Siberia, introduced via a proximal source related to the inhabitants of either the Eurasian steppe or Armenia. Modern Greeks resemble the Mycenaeans, but with some additional dilution of the Early Neolithic ancestry. Our results support the idea of continuity but not isolation in the history of populations of the Aegean, before and after the time of its earliest civilizations. © 2017 Macmillan Publishers Limited, part of Springer Nature.

Abstract

Here we report the Simons Genome Diversity Project data set: high quality genomes from 300 individuals from 142 diverse populations. These genomes include at least 5.8 million base pairs that are not present in the human reference genome. Our analysis reveals key features of the landscape of human genome variation, including that the rate of accumulation of mutations has accelerated by about 5% in non-Africans compared to Africans since divergence. We show that the ancestors of some pairs of present-day human populations were substantially separated by 100,000 years ago, well before the archaeologically attested onset of behavioural modernity. We also demonstrate that indigenous Australians, New Guineans and Andamanese do not derive substantial ancestry from an early dispersal of modern humans; instead, their modern human ancestry is consistent with coming from the same source as that of other non-Africans.

Abstract

PURPOSE: To report a case in which a persistent high-flow type II endoleak after endovascular aneurysm repair (EVAR) of a leaking abdominal aortic aneurysm (AAA) complicated by an aortocaval fistula was repaired with a stent-graft in the inferior vena cava (IVC). CASE REPORT: A 76-year-old man underwent emergent EVAR with an aortomonoiliac device to exclude a leaking 9-cm AAA. The 30-day computed tomography (CT) scan showed 2-mm sac expansion and a type II endoleak arising from a lumbar artery; the outflow vessel was the inferior vena cava (IVC) via a fistula that was not depicted on the non-contrast preoperative CT or the intraoperative angiogram. No intervention was deemed necessary at the time. Six months after EVAR, the AAA had not expanded further, but the fistula between the sac and the IVC was larger in diameter. A tubular stent-graft was implanted in the IVC to seal the defect. No complications have been noted up to 36 months after the IVC stent-graft procedure. CONCLUSION: Aortocaval fistulae should be excluded in the case of persistent type II endoleaks after EVAR for ruptured AAAs. IVC endografting is a minimally invasive alternative to treat such a complication, with promising midterm results in this patient. J Endovasc Ther

Abstract

We sequenced the genomes of a ∼7,000-year-old farmer from Germany and eight ∼8,000-year-old hunter-gatherers from Luxembourg and Sweden. We analysed these and other ancient genomes with 2,345 contemporary humans to show that most present-day Europeans derive from at least three highly differentiated populations: west European hunter-gatherers, who contributed ancestry to all Europeans but not to Near Easterners; ancient north Eurasians related to Upper Palaeolithic Siberians, who contributed to both Europeans and Near Easterners; and early European farmers, who were mainly of Near Eastern origin but also harboured west European hunter-gatherer related ancestry. We model these populations' deep relationships and show that early European farmers had ∼44% ancestry from a 'basal Eurasian' population that split before the diversification of other non-African lineages.

Abstract

Simian virus 40 large T antigen is a J-domain-containing protein with multiple functions. Among its numerous activities, T antigen can bind heat shock cognate 70 (hsc70) but the biological significance of this interaction has not been fully understood. Here, we show that T antigen can act as an hsc70 co-chaperone enhancing the protein-folding ability of the hsc70 chaperone machine. We also show that T antigen exerts its function in collaboration with the mammalian homologue of DnaJ. Moreover, we show that the participation of T antigen in the hsc70 chaperone machine has cell-type-specific characteristics. FEBS J

Abstract

A 70-kDa heat-shock-protein (hsp 70) expression vector which contains the human hsp 70 gene linked to the human beta-actin promoter, was constructed and used to transfect CV1 monkey cells. Stably transfected CV1 clones were isolated which constitutively synthesized increased amounts of hsp70 at normal temperature. It is shown that these clones are resistant to elevated temperature. This finding indicates that hsp70 is involved in the protection of the cells against a lethal heat treatment and maybe responsible for the phenomenon of thermotolerance. Eur J Biochem

Abstract

Two pesticides, the insecticide imidacloprid and the herbicide acetochlor, were evaluated for their insecticidal and genotoxic effects in Drosophila melanogaster. Their insecticidal effects were assessed by calculating LC50 values after acute or chronic exposure of larvae and adults to different concentrations of the test compounds. After acute exposure, the LC50 of imidacloprid was 7.59 × 10−5 M for larvae and 1.43 × 10−4 M for adults, and after chronic exposure, it was 2.67 × 10−5 M and 6.09 × 10−5 M for larvae and adults, respectively. On the contrary, the herbicide acetochlor showed no acute or chronic insecticidal effect against either larvae or adults, even at very high concentrations (8 × 10−3 M). For the evaluation of genotoxic properties of the two pesticides, the Somatic Mutation and Recombination Test in D. melanogaster was used. Our results suggest that neither imidacloprid nor acetochlor exhibits mutagenic or recombinogenic activity at applicable concentrations. [ABSTRACT FROM AUTHOR]

41. Nuclear lamina heterogeneity in mammalian cells. Differential expression of the major lamins and variations in lamin B phosphorylation.

Worman, H J, Lazaridis, I, and Georgatos, S D

Abstract

We have studied the molecular composition of the nuclear lamina in rat tissues of distinct embryological origin and the occurrence of the nuclear lamins during in vitro differentiation of the mouse F9 teratocarcinoma cell line. Immunochemical analysis demonstrated that all rat tissues contained the three major lamin forms (lamins A, B, and C) previously recognized in rat liver nuclei; however, other minor cross-reactive components were also identified in some tissues. The amount of the 67-kDa lamin B complexed with lamins A and C in the laminae of different tissues ranged from a stoichiometry of much less than 1 to approximately 1. Furthermore, it was found that F9 stem cells and their differentiated progeny express only lamin B, and Northern blotting analysis indicated that these cells fail to accumulate lamin A and C mRNA. Chemical cleavages and peptide mapping suggested that the 67-kDa lamin B form was of similar primary structure in all differentiated tissues and F9 cells. Employing antibodies with different affinities for phosphorylated and nonphosphorylated lamin B, we showed that the apparent invariance in the expression of this polypeptide is overriden by a heterogeneity produced via tissue-specific phosphorylation. Because similar differences in antibody recognition could be reproduced in vitro by phosphorylating lamin B with protein kinase A, we have concluded that the tissue-specific modifications of this protein may occur at consensus sites recognized by this enzyme. These data support the hypotheses that the lamins can form functional laminae by associating at various combinations, and that processes including differential lamin synthesis and post-translational modification can produce a steady state lamina heterogeneity.

Abstract

The effects of heat treatment of CV1 cells infected with simian virus 40 (SV40) on viral and cellular protein synthesis were investigated by one-dimensional and two-dimensional polyacrylamide gel electrophoresis. A 12-h heat treatment during the late phase of the viral life-cycle inhibits VP1 synthesis. No inhibition of normal cellular proteins is apparent, but heat-shock proteins are strongly induced and accumulate in the cells. Inhibition of VP1 synthesis in infected cells is demonstrated to occur also after arsenite treatment, another agent known to induce heat-shock proteins. Northern blot analysis of cytoplasmic RNA demonstrated a decrease in the abundance of late SV40 mRNAs thus showing that the inhibition occurs at the transcriptional or immediately post-transcriptional level. Cumulative labeling with [3H]thymidine of viral DNA showed that the decrease in the abundance of late mRNAs is not due to a blocking of viral DNA synthesis. Immunofluorescence microscopy and immunoprecipitation analysis show that heat and arsenite treatments also affect the synthesis of T antigen. These results suggest that heat-shock proteins may play a role in the inhibition of SV40 virus gene functions. Eur J Biochem

Abstract

AIM: The aim of this study is to investigate the safety and efficacy of abdominal aortic aneurysm (AAA) repair with modular bifurcated Talent stent-graft. METHODS: Between September 2001 and September 2005, 85 patients with infrarenal AAA underwent treatment with Talent stent-graft. There were 83 men and 2 women with a median age of 69.3 years. Anatomy of the abdominal aorta and the iliac arteries was investigated with high resolution contrast CT together with digital subtraction angiography. The majority of patients had comorbid illnesses like arterial hypertension (60%), CAD (38%) and previous CABG (26%). Duration of follow-up period ranged from 1 to 48 months (median 18 months). RESULTS: Repair was performed with transrenal fixation of the bifurcated Talent stent-graft under regional anesthesia in 80% of all cases. Technical success rate was 97.6%. Aneurysm related mortality was 2.4% due to aneurysm rupture in the postoperative period. Overall mortality rate was 9.4%. Morbidity rate was 16.5%. Immediate conversion to open repair was necessary in 1 patient (1.2%). Endoleak rate was 4.8% at 1 month follow-up period. Secondary intervention was required in 1.2% of patients. Iliac limb occlusion was detected in 1 patient (1.2%). CONCLUSIONS: Talent stent-graft exhibits a high degree of technical success in AAA repair in patients with comorbid conditions with a low perioperative morbidity and mortality rate. Int Angiol

Abstract

We sequenced the genomes of a 7,000-year-old farmer from Germany and eight 8,000-year-old hunter-gatherers from Luxembourg and Sweden. We analysed these and other ancient genomes¹-₄ with 2,345 contemporary humans to show that most present-day Europeans derive from at least three highly differentiated populations:west European hunter-gatherers, who contributed ancestry to all Europeans but not to Near Easterners; ancient north Eurasians related to Upper Palaeolithic Siberians³, who contributed to both Europeans and Near Easterners; and early European farmers, who were mainly of Near Eastern origin but also harboured west European hunter-gatherer related ancestry.We model these populations’ deep relationships and show that early European farmers had 44% ancestry from a ‘basal Eurasian’ population that split before the diversification of other non-African lineages
