Hotspots of contamination coincide with major urban agglomerations, including Delhi, Kolkata, Kanpur, Varanasi, and Patna. Pesticides levels have decreased at most of the sites over recent decades, while potentially harmful concentrations of polychlorinated biphenyls (PCBs), organotin compounds (OTCs), and some PPCPs have been detected in the last ten years. Considering the limited geographical coverage of sampling and number of analyzed compounds, this review highlights the need for a more careful selection of locations, compounds and environmental matrices, prioritizing PPCPs and catchment-scale, source-to-sink studies.HIF1-alpha expression defines metabolic compartments in the developing heart, promoting glycolytic program in the compact myocardium and mitochondrial enrichment in the trabeculae. Nonetheless, its role in cardiogenesis is debated. To assess the importance of HIF1-alpha during heart development and the influence of glycolysis in ventricular chamber formation, herein we generated conditional knockout models of Hif1a in Nkx2.5 cardiac progenitors and cardiomyocytes. Deletion of Hif1a impairs embryonic glycolysis without influencing cardiomyocyte proliferation and results in increased mitochondrial number and transient activation of amino acid catabolism together with HIF2α and ATF4 upregulation by E12.5. Hif1a mutants display normal fatty acid oxidation program and do not show cardiac dysfunction in the adulthood. Our results demonstrate that cardiac HIF1 signaling and glycolysis are dispensable for mouse heart development and reveal the metabolic flexibility of the embryonic myocardium to consume amino acids, raising the potential use of alternative metabolic substrates as therapeutic interventions during ischemic events.Classically, hematopoietic stem cell (HSC) differentiation is assumed to occur via progenitor compartments of decreasing plasticity and increasing maturity in a specific, hierarchical manner. The classical hierarchy has been challenged in the past by alternative differentiation pathways. We abstracted experimental evidence into 10 differentiation hierarchies, each comprising 7 cell type compartments. By fitting ordinary differential equation models with realistic waiting time distributions to time-resolved data of differentiating HSCs from 10 healthy human donors, we identified plausible lineage hierarchies and rejected others. We found that, for most donors, the classical model of hematopoiesis is preferred. Surprisingly, multipotent lymphoid progenitor differentiation into granulocyte-monocyte progenitors is plausible in 90% of samples. An in silico analysis confirmed that, even for strong noise, the classical model can be identified robustly. Our computational approach infers differentiation hierarchies in a personalized fashion and can be used to gain insights into kinetic alterations of diseased hematopoiesis.An 82-year-old male was transferred for an abdominal CT scan for chronic cutaneous fistulation at the level of the right abdominal wall. Previous CT and ultrasound imaging described recurrent collections in the right abdominal wall, requiring CT guided abscess drainage. The abdominal CT scan revealed an abscess in between the internal oblique and transversus abdominis muscle layers of the right flank, with significant fat stranding and loss of the intermuscular fat planes ( Figure 1 ). Inside this abscess, we notice a spontaneous hyperdense nodular lesion (Hounsfield Units 130), which doesn't enhance after contrast injection ( Figure 1 arrow). link= click here Looking back at the previous CT scans we discern the presence of this hyperdense lesion, which tends to migrate over time over a small distance along the abdominal wall ( Figure 2 A-D arrow). We can trace this back on the numerous previous scans, with different local tissue reactions over time. The first performed CT 8 years prior reveals a perforated calculous cholecystitis, containing multiple cholecystolithiases with the same density as our previously mentioned hyperdense lesion ( Figure 3 arrow). Thus, raising the suspicion of a biliary origin of this corpus alienum.

To evaluate the correlation of maximum standardized uptake values (SUV
) of
F-Fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) with the apparent diffusion coefficient (ADC) of diffusion weighted imaging (DWI) in musculoskeletal malignancies.
Institutional ethics committee approved this retrospective study. Twenty-seven patients (mean age 44.85 ± 24.07; 17 men and 10 women) with a total of 29 musculoskeletal tumors underwent both FDG-PET/CT and DWI between January 2017 and March 2020. Region-of-interest (ROI)-based maximal standardized uptake values (SUV
) of the tumors were measured on FDG-PET/CT images. Two radiologists measured lesions' mean and minimum apparent diffusion coefficient (ADC
and ADC
) using five distinct ROIs on DWI images. Pearson correlation analysis was used to assess the correlation between SUV
and ADC values.
There were 18 soft tissue tumors (62.1%) and 11 bone tumors (37.9%) with a mean maximum diameter of 9.4 ± 6.2 cm. The mean SUV
, ADC
and ADC
of the whole lesions were 12.93 ± 9.63, 0.85 ± 0.28 × 10
mm
/s and 0.61 ± 0.27 × 10
mm
/s, respectively. click here SUV
had a weak correlation with tumor maximum diameter (r = 0.378, p = 0.043), whereas ADC
and ADC
had none. link2 There was strong inverse correlation between SUV
and both ADC
(r = -0.616, p < 0.001) and ADC
(r = -0.638, p < 0.001).
In musculoskeletal tumors, quantitative markers of FDG uptake and diffusion restriction strongly correlate.

The current SARS-CoV-2 pandemic has escalated rapidly since December 2019. Understanding the ophthalmic manifestations in patients and animal models of the novel coronavirus may have implications for disease surveillance. Recognition of the potential for viral transmission through the tear film has ramification for protection of patients, physicians, and the public.
Information from relevant published journal articles was surveyed using a computerized PubMed search and public health websites. We summarize current knowledge of ophthalmic manifestations of SARS-CoV-2 infection in patients and animal models, risk mitigation measures for patients and their providers, and implications for retina specialists.
SARS-CoV-2 is efficiently transmitted among humans, and while the clinical course is mild in the majority of infected patients, severe complications including pneumonia, acute respiratory distress syndrome, and death can ensue, most often in elderly patients and individuals with co-morbidities. Conjunctiransmission via respiratory aerosols supports eye protection, mask and gloves as part of infection prevention and control recommendations for retina providers. click here Disease surveillance during the COVID-19 pandemic outbreak may also include ongoing evaluation for uveitis and retinal disease given prior findings observed in animal models and a recent report of retinal manifestations.We report a rare case of a persistent sciatic artery in a 59-year-old woman who had presented with unilateral acute limb ischemia. link3 A heparin infusion was started. A right lower extremity arterial duplex ultrasound scan showed an occluded superficial femoral artery and underwent catheter-directed thrombolysis of her right popliteal artery, which was fed by a persistent sciatic artery. After recovery, computed tomography angiography was performed, which confirmed a persistent sciatic artery of the right lower extremity. The patient had presented with thrombotic disease secondary to atherosclerosis of popliteal and tibial arteries, in contrast to the more commonly seen aneurysmal disease with thrombosis.We present two preloaded techniques to facilitate gate cannulation during endovascular aortic repair. In the first case, we relined the aorta using a Gore iliac branch endoprosthesis (WL Gore and Associates, Flagstaff, Ariz) for acute occlusion. This allowed for preloading the contralateral gate, which was compressed when deployed, and subsequently dilated open over the preloaded wire to allow for cannulation. The second patient had had an infrarenal aneurysm. A Gore Excluder was partially deployed extracorporeally to preload the gate from the ipsilateral side. link2 The "snare ride" technique was used to rapidly cannulate the gate. Preloaded wire techniques during endovascular aortic repair can facilitate rapid gate cannulation, especially in patients with challenging anatomy.A 54-year-old woman presented with an enlarging, pulsatile left neck mass and a history of Takayasu arteritis. She had seven prior cervical vascular reconstructions, including a prosthetic right-to-left carotid crossover, and left vertebral and subclavian bypasses done with saphenous vein. The skin of her neck was scarred and thin. The anastomotic pseudoaneurysms were resected, the left carotid bifurcation was reconstructed with the cryopreserved femoral artery because of the concern about wound healing, and the subclavian and vertebral vein grafts were reimplanted. Intraoperative management, clamp sites and sequence, manner of shunting, choice of conduit, and wound healing were important considerations.A 61-year-old man presented with chronic limb threatening ischemia due to reocclusion of a femoropopliteal (FP) bypass using a saphenous vein graft (SVG). After performing endovascular intervention using plain angioplasty and drug-coated balloon and drug-eluting stent implantation of the proximal anastomosis of FP bypass, refractory early reocclusion occurred during the perioperative period. Thus, we decided to alternatively place a stent-graft in the occluded FP bypass. link3 After the SVG had been dilated using a high-pressure balloon, a stent-graft was successfully placed. This alternative therapy using a stent-graft prevented SVG FP bypass reocclusion, and the patient's ulcers had completely healed within 1 month.Transcarotid arterial revascularization (TCAR) with flow reversal offers a less invasive option for carotid revascularization in high-risk surgical patients. TCAR has been shown to have similar complication rates for stroke and mortality compared with carotid endarterectomy and lower complication rates compared with transfemoral carotid artery stenting. A relative contraindication for carotid stenting includes heavily calcified lesions. Intravascular lithotripsy has been approved for use in other vascular beds for endovascular treatment of heavily calcified lesions. In the present report, we have demonstrated the application of intravascular lithotripsy for heavily calcified carotid lesions, enabling treatment with TCAR for those who otherwise might be at high risk of transfemoral carotid artery stenting or carotid endarterectomy.Portal vein aneurysms are rare pathologic entities. A 3.7-cm portal vein aneurysm was incidentally discovered in an 80-year-old male patient on imaging for acute abdominal pain secondary to an incarcerated diaphragmatic hernia. The aneurysm was resected, and primary repair of the portal vein was performed during a second-look operation after repair of the incarcerated hernia. Operative intervention was chosen for this patient because of the aneurysm's size and the additional indication for abdominal exploration.
