patency-of-reverse-saphenous-vein-graft-for-revascularization-of-lower-limbs-...Peertechz Publications
Objectives: Diabetic patients are prone to early development of vasculopathy, resulting in lower limb ischemia, which can lead to non-healing ulcers, foot infection, loss of limb, and even death. These patients need revascularization of their limb either using endovascular or open surgical techniques. Not all patients are suitable for endovascular treatment warranting the open surgical revascularization techniques.
The objective of this study was to evaluate the patency of arterial bypass grafting using reverse saphenous vein graft in the treatment of peripheral vascular disease of the lower limbs in diabetic patients.Study ties use of dialysis catheters to greater infection risk in patients
Dialysis catheters used to create a pathway to a patient's blood have been associated with a greater infection, cardiovascular problems, and mortality risk than other forms of procedures that access a patient's blood supply in dialysis treatment, a new study claims. See the Dialysis Injury Helpline at dialysisinjuryhelpline.com for comprehensive information pertaining to the serious adverse health consequences GranuFlo and NaturaLyte have been reported to cause.

RVADs/LVADs and all things mechanical by Dr Jayshree Lavana
Survival in patients with advanced heart failure (AHF) has improved over the last 2 decades. An increasing number of patients however, are dying with progressive heart failure over the same duration. Optimal utilization of medical therapies and devices like implantable defibrillators and biventricular pacemakers are the likely reasons patients are surviving longer albeit with progressive HF.
Evolution in mechanical circulatory support (MCS) devices has occurred over the same period, such that they can now be rapidly instituted providing support for pump failure, often percutaneously, with timely restitution of physiologic and metabolic derangements with fewer complications.
MCS devices can be classified as Short term and Long term. Short term devices such as Intraaortic balloon pumps (IABP), Impella ®, TandemHeart® or Venoarterial extracorporeal membrane oxygenation (VA – ECMO) using a Cardiohelp® device, are usually employed as ‘Bridge to Recovery’(BTR) or Bridge to Decision’(BTD), usually in acute settings. Long term devices such as implantable left ventricular assist devices (LVADs) e.g. Heartmate II® & 3®, Heart ware HVAD® are implanted as ‘Bridge to transplant’ (BTT) or ‘Destination therapy’ (DT) usually in patients ‘sliding’ on inotropes when they are transplant eligible (BTT) or ineligible (DT) respectively.
Ventricular assist devices have traditionally been developed for left ventricular support in case of severe left heart or biventricular dysfunction. Historically, right ventricular (RV) dysfunction following LVAD implantation or as a component of biventricular dysfunction was managed with either medical therapy, temporary VADs (i.e. ECMO configuration with continuous flow centrifugal pumps like CentriMag®, Rotaflow ®) or occasionally with LVADs placed on the right side. Recently the Impella RP® and ProtekDuo®, percutaneously placed pumps with inflow in the inferior vena cava & right atrium respectively and outflow in pulmonary artery, have become available as less invasive options, for short term RV support.
The Syncardia® is the only approved total artificial heart system currently in use; however various biventricular, total heart systems (e.g. BiVACOR®) in development show promise.
Mechanical circulatory devices provide attractive, viable, physiologically plausible ventricular support options that can be used effectively in carefully selected patients.

This study analyzed data from the Polish National Registry (ORPKI) comparing outcomes of radial versus femoral access for percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI). After propensity score matching, there were 6,542 pairs of patients. The results showed that radial access was associated with lower periprocedural mortality and significantly reduced bleeding complications at the access site both during hospitalization and after PCI compared to femoral access. However, allergic reactions occurred more frequently with radial access. In conclusion, radial access provided benefits over femoral access in reducing bleeding while being as effective for treating STEMI patients.Preventing Interruptions in IV Carrier Delivery of Vasoactive Drips in Cardia...

Background: There are no safe operations in cardiac surgery. Every operation can possibly go wrong. We therefore retrospectively evaluated all cardiac operations lasting more than 300 minutes of bypass time at our institution to evaluate outcome and factors relevant for perioperative mortality and morbidity. .Morning report 3-3-14
Lewis Washkansky was the recipient of the first successful human heart transplant in 1967 in South Africa. While he survived over two weeks, he ultimately succumbed to pneumonia. Now approximately 2,000 heart transplants are performed annually in the US, allowing patients to live longer, healthier lives. The most common causes of death after transplant are graft failure early on, opportunistic infections between 6 months to a year post-transplant, and acute rejection within the first three years. Cardiac allograft vasculopathy (CAV), where the transplanted coronary arteries develop atherosclerosis, increases risk of death beyond the first year. Screening for CAV involves annual coronary angiography. Treatment focuses on controlling hypertension and
Prosthetic valve thrombosis
Prosthetic valve thrombosis (PVT) occurs when a blood clot forms on an artificial heart valve. It is more common with mechanical valves compared to bioprosthetic valves. Risk factors include being under-anticoagulated, poor cardiac output, pregnancy, and hypercoagulable states. Echocardiography can diagnose PVT by detecting increased transvalvular gradients, thickened valve cusps, limited cusp motion, or visible thrombus. For severe PVT with heart failure symptoms, emergency surgery is recommended. For less severe cases, fibrinolytic therapy can restore normal valve function in 64% of patients and is a reasonable first-line treatment alternative to surgery.

In the past decades, treatment of the temporal bone traumas (TBTs) was undeniably improved by advances in neuroradiological and in neuro-oto-surgical fields. However, these advances did not systematically enhance the quality of the approach to TBTs. Maybe they did not systematically target towards treatment- guidelines standardization. We suggest a simplified approach to TBTs, trying to enhance the communication among the different specialists involved in the matter, above all between the radiologists and not-radiologists.pasteurella-canis-as-a-cause-of-septic-arthritis-and-soft-tissue-infection-af...

This case report describes a 66-year-old farmer woman who developed a soft tissue infection and septic arthritis in her left wrist after being bitten by a sick lamb. The lamb had previously been bitten by a dog. Microbiological examination of fluid from the infected wrist joint identified Pasteurella canis, which is commonly found in dog bites but has not previously been reported to cause infection from a sheep bite. The patient's symptoms, including an infected left hand and wrist septic arthritis, developed after the lamb bite. P. canis was identified as the causative agent by its growth in culture and Gram stain appearance of Gram-negative cocobacilli. This suggests P. canis should be consideredOJEB

Introduction: Rabies is a viral disease that causes nearly thousands of death globally per year. Vaccination against rabies generates virus neutralizing antibodies and is the most successful and cost effective method of preventing the disease. In the present study, we have evaluated the adjuvant property of supercritical carbon dioxide extract (SCE) 300ET of Seabuckthorn (SBT) leaves against inactivated rabies virus antigen in Swiss albino mice.
Methods: Mice were grouped as PBS control; inactivated rabies antigen (Rb) control; 300ET+Rb and Algel+Rb. All the mice were primed on day 1 followed by single booster at day 14. Sera were collected at different time points for RVNA analysis. Additionally, the effect of SCE on CD8+Granzyme B+ Cytotoxic T Lymphocyte (CTL) response, surface markers and cytokine levels were measured.is-there-a-connection-between-inflammatory-bowel-disease-exacerbation,-clostr...

Unexpected acute laryngeal obstruction is most often caused by foreign bodies or edema and rarely by cysts, infection, or neoplasia. Neoplastic cases include soft tissue tumors and benign epithelial tumors. We report a case of fatal, unexpected, sudden asphyxia due to laryngeal obstruction by a papillary squamous cell carcinoma, a unique presentation of laryngeal squamous cell carcinoma and in this case an unusual histologic pattern. A 61-year-old man experienced respiratory distress while at work. Laryngeal obstruction was discovered in the emergency department. Cricothyrotomy was performed, but his blood oxygen saturation levels failed to improve and he died after a prolonged resuscitation. Autopsy revealed a papillary squamous cell carcinoma on the inferior aspect of the right vocal fold. We suggest that this unusual presentation of laryngeal carcinoma may be due to the unusual histologic features of the tumor.pixi
This document discusses the management of antiplatelet therapy in patients with coronary stents undergoing urologic surgery. It presents guidelines from cardiologic and urologic societies on balancing the risks of bleeding from surgery and thrombosis from discontinuing antiplatelet drugs. For high-risk procedures like TURP, alternatives like laser procedures that reduce bleeding risk even on antiplatelet therapy are recommended. The guidelines stratify thrombotic risk based on stent type and time since placement, and bleeding risk based on procedure invasiveness. They provide recommendations on continuing, holding, or bridging antiplatelet drugs pre- and post-surgery based on thrombotic and bleeding risk levels.

The survey summarizes current practices regarding transradial access (TRA) for coronary procedures in Italy based on responses from 508 interventional cardiologists. Key findings include: 1) TRA is widely adopted in Italy for 75% of all interventional cardiology procedures; 2) assessment of dual hand circulation and use of spasmolytic drugs during the procedure is not routine; and 3) while TRA is the preferred approach for most procedures, its use for complex cases such as left main intervention and CTO remains an issue requiring further study.Ruzsa Z - AIMRADIAL 2014 Endovascular - Carotid artery stenting

Takayasu's arteritis is an inflammatory disease that causes stenosis of the aorta and its main branches. It most commonly affects young women in Asia. Symptoms vary depending on the arteries affected but may include headaches, fatigue, limb claudication, and hypertension. Diagnosis involves assessing symptoms, physical exam findings like blood pressure differences between limbs, and imaging tests like angiograms. Treatment consists of corticosteroids and immunosuppressive drugs to control inflammation, with surgery as needed for complications from narrowed arteries. Strict management of cardiovascular risk factors is also important.

Introduction: Rabies is a viral disease that causes nearly thousands of death globally per year. Vaccination against rabies generates virus neutralizing antibodies and is the most successful and cost effective method of preventing the disease. In the present study, we have evaluated the adjuvant property of supercritical carbon dioxide extract (SCE) 300ET of Seabuckthorn (SBT) leaves against inactivated rabies virus antigen in Swiss albino mice.
Methods: Mice were grouped as PBS control; inactivated rabies antigen (Rb) control; 300ET+Rb and Algel+Rb. All the mice were primed on day 1 followed by single booster at day 14. Sera were collected at different time points for RVNA analysis. Additionally, the effect of SCE on CD8+Granzyme B+ Cytotoxic T Lymphocyte (CTL) response, surface markers and cytokine levels were measured.is-there-a-connection-between-inflammatory-bowel-disease-exacerbation,-clostr...

Unexpected acute laryngeal obstruction is most often caused by foreign bodies or edema and rarely by cysts, infection, or neoplasia. Neoplastic cases include soft tissue tumors and benign epithelial tumors. We report a case of fatal, unexpected, sudden asphyxia due to laryngeal obstruction by a papillary squamous cell carcinoma, a unique presentation of laryngeal squamous cell carcinoma and in this case an unusual histologic pattern. A 61-year-old man experienced respiratory distress while at work. Laryngeal obstruction was discovered in the emergency department. Cricothyrotomy was performed, but his blood oxygen saturation levels failed to improve and he died after a prolonged resuscitation. Autopsy revealed a papillary squamous cell carcinoma on the inferior aspect of the right vocal fold. We suggest that this unusual presentation of laryngeal carcinoma may be due to the unusual histologic features of the tumor.Viewers also liked (12)

This document discusses the management of antiplatelet therapy in patients with coronary stents undergoing urologic surgery. It presents guidelines from cardiologic and urologic societies on balancing the risks of bleeding from surgery and thrombosis from discontinuing antiplatelet drugs. For high-risk procedures like TURP, alternatives like laser procedures that reduce bleeding risk even on antiplatelet therapy are recommended. The guidelines stratify thrombotic risk based on stent type and time since placement, and bleeding risk based on procedure invasiveness. They provide recommendations on continuing, holding, or bridging antiplatelet drugs pre- and post-surgery based on thrombotic and bleeding risk levels.

The survey summarizes current practices regarding transradial access (TRA) for coronary procedures in Italy based on responses from 508 interventional cardiologists. Key findings include: 1) TRA is widely adopted in Italy for 75% of all interventional cardiology procedures; 2) assessment of dual hand circulation and use of spasmolytic drugs during the procedure is not routine; and 3) while TRA is the preferred approach for most procedures, its use for complex cases such as left main intervention and CTO remains an issue requiring further study.Ruzsa Z - AIMRADIAL 2014 Endovascular - Carotid artery stenting

A randomised comparison of transradial and transfemoral approach for carotid artery stenting: RADCAR study (RADial access for CARotid artery stenting)Takayasu arteritis
Takayasu's arteritis is an inflammatory disease that causes stenosis of the aorta and its main branches. It most commonly affects young women in Asia. Symptoms vary depending on the arteries affected but may include headaches, fatigue, limb claudication, and hypertension. Diagnosis involves assessing symptoms, physical exam findings like blood pressure differences between limbs, and imaging tests like angiograms. Treatment consists of corticosteroids and immunosuppressive drugs to control inflammation, with surgery as needed for complications from narrowed arteries. Strict management of cardiovascular risk factors is also important.
OSCILLATORY FLOW OF BLOOD IN POROUS VESSEL OF A STENOSED ARTERY WITH VARIABLE...
This paper presents a theoretical study of oscillatory flow of blood in stenosed artery in the presence of Magnetic field with variable viscosity. The fluid (blood) medium is assumed to be porous in nature. The governing equation for laminar incompressible fully developed and Newtonian fluid by assuming time dependent exponential pressure gradiant subject to the boundary conditions is solved by using the Frobenius method. The variable viscosity of blood depending on hematocrit is taken into account in order to improve resemblance to the real situation. It is assumed that the surface roughness is cosine shaped and the maximum height of roughness is very small compared with radius of the unconstructed tube. The analytical expression for velocity component (V), Volumetric flow rate (Q) and wall shear stress ( ) are obtained. The effect of magnetic field (B0), Hartmann number (M) and maximum Hematocrit at the center of the arterial segment (H) on velocity, flow rate and stress are computed graphically.
Advances in the endovascular management
The document summarizes evidence on endovascular management of descending thoracic aorta pathologies, including aneurysms, dissections, and traumatic injuries. It describes outcomes from registries and trials showing technical success over 98% and reduced mortality and paraplegia compared to open surgery. However, no randomized trials have been conducted. It also notes that endografting is superior to open repair for complicated type B dissections but inferior to medical management for uncomplicated dissections. Endovascular treatment of traumatic injuries is feasible but lacks proven benefit.

This document discusses the benefits of performing pre-procedural radial artery angiography in STEMI patients undergoing primary percutaneous coronary intervention (PPCI) via the transradial approach. It presents data from a study of over 3,600 STEMI patients who underwent PPCI. Radial artery angiography was able to identify anatomical variations in 8.6% of patients. These variations were associated with higher rates of radial artery spasm, access site bleeding complications, and crossover to alternative access sites. The study concludes that routine radial artery angiography prior to PPCI can help identify variations that may impact the procedure, allowing operators to be better prepared to address challenges and potentially improving outcomes.The expanding clinical applications of tevar
The document summarizes the expanding clinical applications of endovascular aneurysm repair (TEVAR) beyond its original use for descending thoracic aneurysms. It discusses how TEVAR is now being used to treat a wider range of thoracic aortic pathologies including dissections, ulcers, trauma, and various complex aneurysms. The document also explores new techniques like branched endografts and debranching procedures that are pushing the anatomic limits of TEVAR proximally and distally. While noting some limitations, it presents data showing TEVAR has led to reduced mortality, complications, and hospital stay compared to open surgery for many thoracic aortic conditions.

This document summarizes a study on using fibrin glue to induce thrombosis of aneurysm sacs during endovascular aneurysm repair (EVAR). The study included 84 patients who underwent EVAR with additional injection of fibrin glue into the aneurysm sac. Follow-up for up to two years found thrombosis of fibrin glue-treated aneurysm sacs in 97.6% of cases. The authors conclude that intraoperative fibrin glue injection is an effective preventive strategy for type II endoleaks and may be considered for routine prevention of type II endoleaks during EVAR.

This study evaluated the incidence of radial artery occlusion (RAO) in 339 patients who underwent a second cardiac catheterization or percutaneous coronary intervention (PCI) using the radial artery approach within 1 year of a previous radial procedure. The incidence of RAO was low at 1.5%, occurring in 5 patients. Risk factors for the cases of RAO included the use of a 6 French catheter and having undergone multiple prior radial procedures. The study concludes that contemporary techniques including slender catheters, manual bandages, and new P2Y12 inhibitors result in low rates of RAO.ISR published
This document discusses a study evaluating the incidence, predictors, and long-term outcomes of patients experiencing in-stent restenosis (ISR) after receiving long drug-eluting stents for coronary arteries. 421 patients received long drug-eluting stents and 371 patients underwent follow up. The overall incidence of ISR was 4%. Risk factors for ISR included diabetes and long lesions. Of those with ISR, 40% underwent repeat PCI, 46.7% underwent bypass surgery, and 13.3% were treated medically. During long-term follow up of 12-26 months, there were no deaths from ISR and the incidence of major adverse cardiac events was low. ISR did not
Hybrid procedure
This document summarizes a study on using hybrid endovascular and open surgical procedures to treat severe multi-level lower extremity arterial disease. 38 patients underwent 40 hybrid procedures between 2013-2015 that combined techniques like remote endarterectomy, stent placement, and bypass surgery. Initial technical success was 100% with mean ABI increase of 0.4. Primary patency rates at 12 months were 86.7% and limb salvage rates were 95%. The conclusion is that hybrid procedures provide an effective less invasive treatment for multi-level lower extremity atherosclerosis.
Aortic regurgitation after tTAVR
This review article discusses aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI). It notes that AR is more common after TAVI than surgical aortic valve replacement, with mild AR observed in about 70% of TAVI patients. Even mild AR has been linked to decreased survival up to two years after the procedure. The review aims to provide an overview of the three types of AR that can occur after TAVI - transvalvular, paravalvular, and supraskirtal - focusing on their different pathophysiological mechanisms. Accurate evaluation and classification of AR is important for understanding its implications, but challenging due to limitations of echocardiography for assessing transcatheter

This document discusses the benefits and risks of transradial intervention (TRI) compared to transfemoral approach (TFA) for primary percutaneous coronary intervention (PCI) in ST-segment elevation myocardial infarction (STEMI) patients.
The main benefits of TRI are reduced access site bleeding, earlier ambulation for patients, and the ability to use more aggressive anticoagulation. However, TRI may be associated with longer procedures, more contrast use, longer fluoroscopy times, and longer door-to-balloon times. Several randomized controlled trials have shown lower rates of major bleeding but similar mortality with TRI compared to TFA. Registry data also suggests lower mortality and bleeding with TRI. Alternative bleeding avoidance strategies like vascular closure devicesValvula mitral conroversias
Mitral stenosis surgery is recommended for adolescent or young adult patients with congenital mitral stenosis who have symptoms such as shortness of breath (NYHA class III or IV) and a mean mitral valve gradient over 10 mm Hg on echocardiography. Mitral valve surgery is also reasonable for asymptomatic patients with mild symptoms (NYHA class II) and a mean gradient over 10 mm Hg, or asymptomatic patients with pulmonary artery systolic pressure over 50 mm Hg and a mean gradient over 10 mm Hg. The effectiveness of surgery is uncertain for asymptomatic patients with new onset atrial fibrillation or embolisms while on anticoagulation.

JAMES WEBB STUDY THE MASSIVE BLACK HOLE SEEDS
The pathway(s) to seeding the massive black holes (MBHs) that exist at the heart of galaxies in the present and distant Universe remains an unsolved problem. Here we categorise, describe and quantitatively discuss the formation pathways of both light and heavy seeds. We emphasise that the most recent computational models suggest that rather than a bimodal-like mass spectrum between light and heavy seeds with light at one end and heavy at the other that instead a continuum exists. Light seeds being more ubiquitous and the heavier seeds becoming less and less abundant due the rarer environmental conditions required for their formation. We therefore examine the different mechanisms that give rise to different seed mass spectrums. We show how and why the mechanisms that produce the heaviest seeds are also among the rarest events in the Universe and are hence extremely unlikely to be the seeds for the vast majority of the MBH population. We quantify, within the limits of the current large uncertainties in the seeding processes, the expected number densities of the seed mass spectrum. We argue that light seeds must be at least 103 to 105 times more numerous than heavy seeds to explain the MBH population as a whole. Based on our current understanding of the seed population this makes heavy seeds (Mseed > 103 M⊙) a significantly more likely pathway given that heavy seeds have an abundance pattern than is close to and likely in excess of 10−4 compared to light seeds. Finally, we examine the current state-of-the-art in numerical calculations and recent observations and plot a path forward for near-future advances in both domains.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid
