description: Context Cytological assessment of pancreatic juice is commonly used to diagnose pancreatic ductal adenocarcinoma; however, the sensitivity of cytological assessment has been reported to be low. MicroRNAs are small RNAs regulating various cellular processes and have recently been identified as possible markers of malignant diseases including pancreatic ductal adenocarcinoma. Objective The purposes of this study were to prove the existence of microRNAs in pancreatic juice and to determine whether specific microRNAs in pancreatic juice could be used for detecting pancreatic ductal adenocarcinoma. Methods Relative expression levels of microRNA-21 and microRNA-155 in formalin-fixed paraffin-embedded tissues of resected specimens (no. 13) and pancreatic juice samples collected using preoperative endoscopic retrograde cholangiopancreatography (no. 21) were quantified and their expression levels were then compared to pancreatic ductal adenocarcinoma and chronic pancreatitis. Results Relative expression levels of microRNA-21 in tissue and pancreatic juice samples were significantly higher in pancreatic ductal adenocarcinoma than those in chronic pancreatitis (P=0.009 and P=0.021, respectively). The same results were obtained in the expression levels of microRNA-155 in tissue and pancreatic juice between pancreatic ductal adenocarcinoma and chronic pancreatitis (P=0.014 and P=0.021, respectively). Expression levels of microRNA-21 and microRNA-155 did not correlate with the preoperative cytological results of pancreatic juice. Conclusion MicroRNA-21 and microRNA-155 in pancreatic juice have the potential of becoming biomarkers for diagnosing pancreatic ductal adenocarcinoma.

description: The failure of the Afghan constitution is attributed to societal values incompatible with democracy, making the country appear ungovernable. The Taliban’s return has sparked debates on regime legitimacy and constitutionalisation. This process will shape Afghanistan’s approach to humanitarian and refugee law, and international aid. The 1964 Constitution was a milestone but was regarded as a failure while the 2004 Constitution, favouring democratic principles, is now illegal. Afghanistan’s challenges stem from a legitimacy crisis, limited citizen participation and parallel institutions. This article examines the successive failure of Afghan constitutions, focusing on the 1923, 1964, and 2004 ones. The study utilises doctrinal legal research, employing normative approaches to evaluate relevant literature, including secondary, primary, and legal documents.

description: Context Pancreatic resection for a metastatic colon, lung cancer or an osteosarcoma has rarely been reported in the literature and there is controversy regarding recurrence and the overall survival of these patients. We herein evaluate the outcome of three patients who underwent pancreaticoduodenectomy for the aforementioned metastatic tumors to the pancreas. Case reports Clinical presentation included pyloric stenosis and acute gastrointestinal bleeding. One patient was asymptomatic and was diagnosed during follow-up for colon cancer. All the pancreatic lesions were located in the head of the pancreas, and the intervals between the diagnosis of the primary cancer and the pancreatic metastases were 6, 14 and 24 months. During exploration of the abdomen, additional metastatic lesions in the small intestine and liver were detected and resected in two patients. One patient died one month after surgery from massive gastrointestinal bleeding. The other two patients experienced relief from their symptoms but died from generalized carcinomatosis 16 and 27 months after pancreaticoduodenectomy. Conclusion Pancreatic resection for metastatic disease may be suggested for selected patients, even those with limited extrapancreatic disease. In this setting, it may offer good palliation and may prolong survival. In cases of acute duodenal bleeding resistant to conservative measures, pancreaticoduodenectomy may represent the only alternative for survival; however, significant morbidity and mortality should be expected.

description: Context Endoscopic retrograde cholangiopancreatography (ERCP) is the procedure of choice for biliary decompression in patients with unresectable pancreatic cancer. However, it may be unsuccessful in 3 to 10% of cases. When ERCP is unsuccessful, the usual alternatives are percutaneous transhepatic biliary drainage or surgery. Recently, several authors have reported the use of EUS-guided biliary drainage in patients with malignant biliary obstructions, with acceptable success and complication rates. We describe three cases of unresectable pancreatic cancer associated with obstructive jaundice, treated by EUS-guided biliary drainage. Case report Three patients with unresectable pancreatic cancer, associated with obstructive jaundice, were included. ERCP was unsuccessful because of complete tumor obstruction of the distal common bile duct and papilla invasion. An EUS-guided rendezvous maneuver was attempted, without success. Then, EUS-guided choledochoduodenostomy, with a partially covered self-expanding metal stent, was performed in the same procedure. There were no early complications and the procedure was also clinically effective in relieving jaundice in all cases. Conclusions EUS-guided biliary drainage is a feasible alternative to percutaneous transhepatic biliary drainage or surgery in unresectable pancreatic cancer with obstructive jaundice when ERCP fails. However, the development of new specific instruments and studies comparing this procedure with percutaneous transhepatic biliary drainage and surgery are needed.

description: Context Choledochal cysts are benign congenital cystic dilatations of the common bile duct. They are usually associated with pancreatobiliary malunion resulting in long-term complications, such as acute pancreatitis and bile duct cancer. However, the occurrence of chronic pancreatitis with a choledochal cyst is rarely reported. Case reports We report three cases of choledochal cysts associated with chronic pancreatitis with their presentation and management. The choledochal cysts were classified according to the Alonso-Lej classification with Todani modifications, based on radiographic and operative findings. Chronic pancreatitis was defined using Marseille criteria (1984). Two patients had a type I choledochal cyst and one had a type IV-A. All cases had chronic calcific pancreatitis with a grossly dilated main pancreatic duct. Abdominal pain was the most common presentation, present in all three patients while jaundice was seen in one patient. The laboratory parameters and MRI/MRCP helped to confirm the diagnosis. All patients underwent cyst excision with drainage and had an uneventful postoperative course. At a median follow-up of 9 months, two patients were asymptomatic and one patient, who developed duodenal obstruction, underwent gastrojejunostomy. Conclusions the association of a choledochal cyst with chronic pancreatitis may be etiologically related. Excision of the cyst with lateral pancreaticojejunostomy can be performed safely and is usually curative.

description: Images of SN1006 have a number of important properties. For instance, the bright limbs coincide spatially in various bands, they have different brightness, and the contrast of brightness varies from radio to gamma-rays. The reasons of such properties and the role of the magnetic field strength are discussed. Simple, almost model-independent methods and analytical approximations for the derivation of the strength of magnetic field from the comparison of radio, X-rays and TeV images of SNR are presented. The methods require the TeV image to be well resolved and accurate, at least to the level of the radio and X-ray maps, in order to put reasonable constraints on magnetic field. If we apply it to the present HESS data, they limit the strength of magnetic field in limbs of SN1006 to values lower than few hundreds micro Gauss. If applied to the Fermi-LAT band, the model predicts same position and same ratio of the surface brightness for GeV photons as for the radio band. We conclude that TeV and GeV future high-resolution data may be very informative about the MF of SN1006.

Empirical Nonlinear Quantum Gravity from the General Theory of Relativity
Creators: name: Yablon, Jay R.
Publisher: name: Zenodo
Year: 2025

description: This article presents an empirical foundation for quantum gravity that accounts for nonlinear gravitational effects, without altering general relativity.  We build on a relation from [14] where κ—the constant coupling the energy tensor with spacetime geometry—depends on: the average rest energy of left-chiral neutrinos; the Fermi vacuum expectation value; and ΔE, a neutrino seesaw fulcrum energy.  This relation links gravity’s weakness to tiny neutrino masses, revealing nonlinear quantum field interactions within Einstein’s unmodified framework.  We uncover multi-graviton scattering by analyzing the Einstein-Hilbert Lagrangian in momentum space for the vacuum solution to the Einstein equation.  This analysis relies solely on general relativity’s inherent nonlinearities, without yet incorporating the novel neutrino mass connection.  Then, by employing this connection to show gravitation mediated by gravitinos, neutrino loops, and gravitons, which also identifies neutrino loops as dark matter quanta and gravitons as dark energy quanta, we integrate the dark sector, modeling both linear and nonlinear gravitational interactions between matter and the dark energy background.  Unlike theories that alter general relativity with new tensors or speculative terms, we rely only upon the unmodified Einstein equation, particle physics data, and cosmological observations.  This conservative, empirically grounded approach preserves general relativity, a theory uncontradicted for over a century, while establishing an empirical foundation for quantum gravity.

description: Context Supraclavicular lymph nodes represent a rare site of metastasis in pancreatic cancer. We report three cases of pancreatic adenocarcinoma with metastases to supraclavicular lymph nodes. Case report A 51-year-old male was diagnosed with locally advanced pancreatic adenocarcinoma on computed tomography (CT) scan. He was recommended neoadjuvant chemotherapy followed by chemoradiation therapy. However, positron emission tomography (PET)/CT scans and subsequent fine needle aspiration cytology showed supraclavicular lymph node metastasis. The patient received systemic chemotherapy for metastatic pancreatic adenocarcinoma. The second patient, a 66-year-old female with pancreatic adenocarcinoma, underwent pancreaticoduodenectomy and was found to have peripancreatic lymph node involvement. She received adjuvant chemotherapy and was followed-up with surveillance CT scans, which did not reveal any metastasis. However, the patient complained of neck swelling. PET/CT scan and biopsy revealed supraclavicular lymph node metastasis from a pancreatic adenocarcinoma primary. The third patient, a 79-year-old male with a past history of thyroid carcinoma who was treated with partial thyroidectomy, developed neck swelling 4 years after his surgery. Fine needle aspiration cytology was consistent with known papillary thyroid carcinoma. Staging evaluations revealed a pancreatic mass for which he underwent subtotal pancreatectomy and splenectomy. Histopathology revealed grade 3 pancreatic adenocarcinoma. Excisional biopsy of a supraclavicular lymph node showed metastatic pancreatic adenocarcinoma. PET/CT results were consistent with these findings. Conclusion In patients with pancreatic adenocarcinoma, supraclavicular lymph node metastasis represents an uncommon, but clinically significant finding that can lead to changes in treatment planning. PET imaging represents a valuable tool in the detection and follow up of these patients.

It describes the organisation and participation in an inter laboratory comparison (ILC) of pH instruments at Marseille in November 2023. The aim of the ILC was to have constant, controllable tanks representing realistic conditions, giving participants from around Europe the chance to intercompare their instruments and be introduced to metrology concepts. The report presents the results and lessons learnt, with advice for future ILCs. The ILC was also a useful opportunity to discuss carbonate chemistry, to meet and discuss with representatives from industry and to look at the community needs for metrology - summaries of these discussions are presented here with recommendations for the future. This deliverable makes conclusions on the type of measurement methods required for ‘weather’ and ‘climate’ goals in the measurement of pH variability.

description: Context Autoimmune pancreatitis is a relatively rare, yet well described cause of chronic pancreatitis. Extrapancreatic findings are now recognized as important manifestations of this entity and viewed as part of a larger disease process tentatively named “IgG4-associated sclerotic disease”. Case report We herein report a case of autoimmune pancreatitis with histopathologically proven gastric involvement. We also describe and illustrate the multidetector-row computed tomography appearance of gastric involvement in IgG4-associated sclerotic disease. Conclusion Autoimmune pancreatitis is increasingly recognized as a multi-systemic disease whose early recognition dramatically affects patient management. Knowledge of the computed tomography appearance of gastric involvement in autoimmune pancreatitis can aid in diagnosis.

Along with observational programmes for determining the topology of the Universe, some small theoretical steps have recently been made. Heuristic Newtonian-like arguments suggest a topological acceleration effect that differs for differing spatial sections. A relativistic spacetime solution solution shows that the effect is not just a Newtonian artefact.

SuperB can contribute to searches for new physics using indirect constraints via precision tests of the standard model. In addition to the indirect constraints, there are a number of direct searches that can be performed at low energy. There is a well motivated programme of measurements to make at SuperB, the results of which will add to our understanding of possible scenarios of physics beyond the standard model.

description: Context Drugs are related to the etiology of acute pancreatitis in approximately 1.4-2.0% of cases. Although antibiotics constitute a small number of the drugs suspected, tetracycline is the most encountered antibiotic among those drugs. Case report A 33-year-old woman was admitted to the emergency room complaining of nausea and abdominal pain after the use of doxycycline 500 mg and ornidazole 500 mg twice daily for three days for a vaginal infection. She experienced epigastric pain, which worsened over time and radiated to her back. After a detailed evaluation, she was diagnosed as having mild acute pancreatitis which improved with medical treatment. All other possible causes of pancreatitis were eliminated. Conclusions Antibiotic-associated pancreatitis usually has a silent and mild course. To the best of our knowledge the literature reports only two cases of doxycycline-induced acute pancreatitis reported and there are no reports of pancreatitis associated with ornidazole. Our case is the first case reported in which doxycycline and ornidazole coadministration induced acute pancreatitis.

description: Context Cystic lymphangiomas originate as benign masses which occur mostly in children especially in the head and neck region and/or the groin. Although abdominal lymphangiomas are rare, they are most commonly reported in adults. In addition, pancreatic involvement is rare. Lymphatic malformation with blockage of the lymphatic flow is the most common etiology leading to the formation of lymphangiomas. Cystic lymphangiomas should always be included in the differential diagnosis of abdominal masses which present with mass effect signs and symptoms. Due to its rarity, it forms a diagnostic and therapeutic challenge for the clinician. Case report We herein report the case of a 43-year-old man with a cystic lymphangioma detected in the head of the pancreas and describe the surgical procedure utilized as the therapeutic medium. Conclusion To remove this mass, we utilized a modified approach to a classic pancreaticoduodenectomy. This technique involved resection of the head of the pancreas while preserving the upper 2nd portion of the duodenum and the ampulla of Vater. The result of our 30-month follow-up of this patient has been very satisfactory with no complications.

description: We present recent results based on a homogeneous analysis of the DEep Spectra of Ionized REgions Database (DESIRED), a compilation of about two hundred high signal-to-noise ratio optical spectra of Galactic and extragalactic HII regions and other photoionized nebulae. We show important insights and caveats about the effects of electron density inhomogeneities and their impact on the temperature structure and metallicity determinations in ionized nebulae. In particular, we demonstrate how internal density variations can be critical for the analysis of infrared fine structure lines, which can lead to significant underestimations of metallicity if not taken into account.

description: Context Idiopathic hyperammonemia is characterized by elevated serum ammonia associated with neurological deterioration of no other obvious etiology associated with relatively normal liver function tests and normal amino-acid levels. Case report We report a case of a 32-year-old woman who presented with acute mental status changes with a pelvic abscess approximately a year following her total pancreatectomy and islet cell transplant surgery. Her ammonia level was elevated to 425 μg/dL. Traditional ammonia-reducing therapies were initiated, but proved ineffective. Metabolic, pharmacologic, microbial, and autoimmune causes for hyperammonemia were excluded. The patient ultimately required continuous veno-venous hemofiltration to decrease her ammonia. Ammonia levels decreased following continuous veno-venous hemofiltration and the patient’s mental status gradually returned to baseline. Conclusion Idiopathic hyperammonemia in the setting of total pancreatectomy and islet cell transplantation has not been reported before. We propose that malnutrition following total pancreatectomy resulting in repressed urea cycle enzyme synthesis may have predisposed for this hyperammonemia.

description: The Landé or g-factors of charge carriers are decisive for the spin-dependent phenomena in solids and provide also information about the underlying electronic band structure. We present a comprehensive set of experimental data for values and anisotropies of the electron and hole Landé factors in hybrid organic-inorganic (MAPbI3, MAPb(Br0.5Cl0.5)3, MAPb(Br0.05Cl0.95)3, FAPbBr3, FA0.9Cs0.1PbI2.8Br0.2, MA=methylammonium and FA=formamidinium) and all-inorganic (CsPbBr3) lead halide perovskites, determined by pump-probe Kerr rotation and spin-flip Raman scattering in magnetic fields up to 10 T at cryogenic temperatures. Further, we use first-principles density functional theory (DFT) calculations in combination with tight-binding and k ⋅ p approaches to calculate microscopically the Landé factors. The results demonstrate their universal dependence on the band gap energy across the different perovskite material classes, which can be summarized in a universal semi-phenomenological expression, in good agreement with experiment.

description: The damped harmonic oscillator under symmetric Lévy white noise shows inhomogeneous phase space, which is in contrast to the homogeneous one of the same oscillator under the Gaussian white noise, as shown in a recent paper [I. M. Sokolov, W. Ebeling, and B. Dybiec, Phys. Rev. E \textbf{83}, 041118 (2011)]. The inhomogeneity of the phase space shows certain correlation between the coordinate and the velocity of the damped oscillator under symmetric Lévy white noise. In the present work we further explore the physical origin of these distinguished features and find that it is due to the combination of the damped effect and heavy tail of the noise. We demonstrate directly this in the reduced coordinate $\tilde{x}$ versus velocity $\tilde{v}$ plots and identify the physics of the anti-association of the coordinate and velocity.

description: We discuss the effects of a trapping space-dependent potential on the critical dynamics of lattice gas models. Scaling arguments provide a dynamic trap-size scaling framework to describe how critical dynamics develops in the large trap-size limit. We present numerical results for the relaxational dynamics of a two-dimensional lattice gas (Ising) model in the presence of a harmonic trap, which support the dynamic trap-size scaling scenario.

description: Las prácticas sacrificiales llegaron a definir la espiritualidad y devoción azteca. Para los conquistadores, esto implicaba que los nahuas tenían una concepción espiritual del universo. Esta noción resultó prometedora para los españoles que se aventuraron al Nuevo Mundo con la intención de lograr su conversión al cristianismo. Para los conquistadores, la brutalidad del sacrificio humano representada en los códices legitimaba la conquista espiritual y física que emprendían, con el fin de erradicar este derramamiento bárbaro de sangre. Sin embargo, las representaciones de la actividad religiosa indígena eran esenciales. Era importante articular, para un público occidental, que estos sacrificios humanos tenían un propósito espiritual para los aztecas. Así, los aztecas potencialmente podrían ser receptivos a los ideales católicos.

description: Context Hemosuccus pancreaticus, a rare cause of intermittent upper gastrointestinal bleeding, is usually caused by the rupture of an aneurysm associated with chronic pancreatitis. Segmental arterial mediolysis is a rare non-arteriosclerotic, non-inflammatory vascular disease characterized by vacuolization and lysis of the arterial smooth muscle cells. Segmental arterial mediolysis often causes intra-abdominal hemorrhage through aneurysm rupture. To our knowledge, hemosuccus pancreaticus associated with segmental arterial mediolysis has not previously been reported. Case report A 59-year-old man had suffered from recurrent episodes of epigastric pain and melena. Laboratory data showed mild anemia and an elevated serum amylase level. Upper gastrointestinal endoscopy revealed bloody pancreatic juice exuding from the papilla of Vater. There were no findings suggestive of chronic pancreatitis, such as pancreatic calcification, irregularity of the pancreatic duct and atrophy of the pancreas. Contrast-enhanced computed tomography revealed a large fusiform aneurysm of the middle-distal splenic artery, and dissection of the proximal splenic artery and celiac artery. Leakage of contrast medium from the aneurysm into the main pancreatic duct was also evident. Angiography clearly revealed a fusiform aneurysm of the splenic artery. This was managed successfully by transarterial coil embolization and the patient has subsequently shown no recurrence of epigastric pain or melena. Conclusion Segmental arterial mediolysis is a very rare cause of hemosuccus pancreaticus not associated with chronic pancreatitis. Transcatheter arterial embolization is useful for treatment of ruptured aneurysm associated with segmental arterial mediolysis.

description: Abstract Djungarian hamsters are small rodents that show pronounced physiological acclimations in response to changes in photoperiod, and unfavorable environmental conditions such as reduced food availability and low external temperature. These include substantial adjustments, such as severe body weight loss and the use of daily torpor. Torpor is a state of decreased physiological activity in eutherms, usually marked by low metabolic rate and a reduced body temperature. In this study, we investigated the effects of photoperiodic acclimation and food deprivation on systemic iron metabolism in Djungarian hamsters. Our study illustrates the association between liver iron levels and the incidence of torpor expression during the course of the experiment. Moreover, we show that both, acclimation to short photoperiods and long-term food restriction, associated with iron sequestration in the liver. This effect was accompanied with hypoferremia and mild reduction in the expression of principal iron-hormone, hepcidin. In addition to iron, the levels of manganese, selenium, and zinc were increased in the liver of hamsters under food restriction. These findings may be important factors for regulating physiological processes in hamsters, since iron and other trace elements are essential for many metabolic and physiological processes.

The topology and polarization of subbeams associated with drifting subpulse emission of pulsar B0943+10 - VI. Analysis of an 8-hour GMRT observation

description: We report analysis of an 8 hr observation of PSR B0943+10 at 325 MHz performed at the Giant Metrewave Radio Telescope (GMRT) in India. B0943+10 is well known for displaying regular sub-pulse drifting and two emission modes. We investigate the modal behavior of B0943+10. By reconstructing an entire 'B' mode from two consecutive 'B' modes, we estimate that the pulsar spends roughly 7.5 hrs in the 'B' mode and about 2.2 hrs in the 'Q' mode, on average. Although the pulsar can switch modes within one pulse, the sub-pulse drift rate changes with a characteristic time of 1.2 hrs over the course of a 'B' mode. Under the subbeam carousel model we find the drift-rate changes are produced by a 10% increase in the average number of subbeams and a 16% increase in the carousel circulation time. We speculate that under the partially screened gap model the increase in circulation time should be related to a small increase in the neutron star surface temperature.

description: Anthropogenic disturbance may increase the emergence of zoonoses. Especially generalists that cope with disturbance and live in close contact with humans and livestock may become reservoirs of zoonotic pathogens. Yet, whether anthropogenic disturbance modifies host-pathogen co-evolutionary relationships in generalists is unknown. We assessed pathogen diversity, neutral genome-wide diversity (SNPs) and adaptive MHC class II diversity in a rodent generalist inhabiting three lowland rainforest landscapes with varying anthropogenic disturbance, and determined which MHC alleles co-occurred more frequently with 13 gastrointestinal nematodes, blood trypanosomes, and four viruses. Pathogen-specific selection pressures varied between landscapes. Genome-wide diversity declined with the degree of disturbance, while MHC diversity was only reduced in the most disturbed landscape. Furthermore, pristine forest landscapes had more functional important MHC–pathogen associations when compared to disturbed forests. We show co-evolutionary links between host and pathogens impoverished in human-disturbed landscapes. This underscores that parasite-mediated selection might change even in generalist species following human disturbance which in turn may facilitate host switching and the emergence of zoonoses.

description: Context Autoimmune pancreatitis is a rare benign disorder that can be confused with pancreatic cancer and the treatment pathway differs dramatically. Case report We present a unique case of pulmonary nodules associated with autoimmune pancreatitis, that was initially confused for pancreatic cancer which resolved spontaneously. Herein we describe the case and subsequent management and discuss the ever increasing incidence of autoimmune pancreatitis. Conclusion Pulmonary nodules associated with equivocal CT findings of primary pancreatic cancer should be treated with suspicion that the primary diagnosis may be incorrect and other differential diagnoses should be explored.

description: Abstract
DDoS attacks, which aim to overwhelm a system with requests, are commonplace in the cyber world. In this type of assault, bandwidth and processing resources are deliberately clogged in order to disrupt the interactions of legitimate users. These attacks operate by inundating the victim's system with a deluge of packets, rendering it inaccessible. Diverging from the singular source of Denial of Service (DoS) attacks, DDoS attacks emanate from a multitude of servers, magnifying their impact. Over the last decade, a concentrated effort has been invested in comprehending the orchestration and authentication of DDoS attacks, resulting in valuable insights into discerning attack patterns and suspicious activities. Currently, the focus has shifted towards real-time detection within the stream of network transactions, constituting a critical research domain. Yet, this focus often sidelines the importance of benchmarking DDoS attack assertions within the streaming data framework. As a remedy, the Anomaly-based Real-Time Prevention (ARTP) framework has been formulated, designed specifically to combat application layer DDoS attacks, particularly targeting web applications. Employing advanced machine learning techniques, ARTP offers adaptable methodologies to swiftly and accurately pinpoint application-layer DDoS attacks. Rigorous testing on a representative LLDoS (Low Level DoS) benchmark dataset has affirmed the resilience and efficiency of the proposed ARTP model, underscoring its capacity to achieve the research objectives set forth.
