Peripheral artery disease is an atherosclerotic occlusive disease that causes limb ischemia and has few effective non-interventional treatments. Stem cell therapy is promising, but concomitant diabetes may limit its effectiveness. We evaluated the therapeutic potential of skeletal muscle pericytes to augment postischemic neovascularization in wild type and type 2 diabetic (T2DM) mice. Wild type C57BL/6J and leptin receptor spontaneous mutation db/db T2DM mice underwent unilateral femoral artery excision to induce limb ischemia...

Compressed sensing (CS) reconstructions of under-sampled measurements generate missing data based on assumptions of image sparsity. Non-contrast time-of-flight MR angiography (TOF-MRA) is a good candidate for CS based acceleration, as MRA images feature bright trees of sparse vessels over a well-suppressed anatomical background signal. A short scan time derived from CS is beneficial for patients of moyamoya disease (MMD) because of the frequency of MR scans. The purpose of this study was to investigate the reliability of TOF-MRA with CS in the evaluation of MMD...

Range of motion (ROM) measured objectively in nodal hand osteoarthritis (NHOA) is missing. Evaluation of collateral ligaments by ultrasound (US) is unknown in NHOA also. To compare ROM in interphalangeal joints in housewives with nodal OA, with a control group by a digital system using angle to voltage (Multielgon). The second objective was to assess correlation between collateral radial and ulnar ligaments thickness and ROM. For this cross-sectional observational study, we assessed 60 hands with symptomatic NHOA and 30 hands of healthy housewives matched for age...

Hand-arm vibration syndrome (HAVS) is a collection of sensory, vascular, and musculoskeletal symptoms caused by repetitive trauma from vibration. This case report demonstrates how to diagnose HAVS on the basis of history, physical examination, and vascular imaging and its treatment options. A 41-year-old man who regularly used vibrating tools presented with nonhealing wounds on his right thumb and third digit. Arteriography revealed occlusions of multiple arteries in his hand with formation of collaterals. We diagnosed HAVS, and his wounds healed after several weeks with appropriate treatment...

The medial collateral ligament is the most commonly injured knee ligament. Valgus stress radiographs are reported to be an effective way to quantify the medial compartment opening. However, most of the techniques require the presence of a physician in the radiograph room to apply a manual valgus stress force, and can only be performed in 1 knee at a time. These techniques, although extremely effective, increase radiation exposure to physicians, are time consuming, and require additional radiographs to compare the side-to-side difference...

Leng et al. [1] described the practical application of a computational fluid dynamics (CFD) model based on Computed Tomography Angiography (CTA) in 85 patients with symptomatic atherosclerotic M1 middle cerebral artery (MCA) stenosis, to virtually measure arterial pressure (AP) across the stenotic segment, according to the theory that translesional pressure gradient (PG) drives arteriologenesis and leptomeningeal collaterals (LMC) development. This is a fundamental pathophysiological issue about the risk of recurrent stroke downstream an intracranial artery stenosis and both the degree of stenosis and the collateral circulation affect it; in WASID trial [2] patients with severe (> 70%) intracranial stenosis and efficient collaterals had a lower risk of recurrent stroke than patients with poor collaterals...

A 46-year-old man presented with severe visual loss and optic atrophy associated with optociliary shunt vessels. The diagnostic work-up revealed intracranial hypertension and cerebral venous sinus stenosis, with no evidence of previous thrombosis. In view of the severe visual dysfunction, both eyes were submitted to optic nerve sheath fenestration. After surgery, a regression of collateral vessels was observed in both eyes.

BACKGROUND: The ophthalmic findings of Susac syndrome (SS) consist of visual field defects related to branch retinal artery occlusion (BRAO), and fluorescein angiography (FA) reveals a unique staining pattern. To date, retinal arterial collateral development has been described only in a single patient. Given that the immunopathological process in SS induces retinal ischemia, it is conceivable that abnormal blood vessel development may occur in affected individuals. METHODS: This is a retrospective observational study...

BACKGROUND: There has been no study on radiologic changes after medial ulnar collateral ligament (MUCL) reconstruction and related clinical features. METHODS: Data from 39 baseball players who underwent MUCL reconstruction were collected and analyzed. The baseball players were classified into 2 groups according to the starting point of the humeral tunnel: (1) the lower tip of the medial epicondyle (group NA, n = 21) and (2) the remnant of the MUCL (group A, n = 18)...

BACKGROUND: Slum dwellers display specific traits when it comes to disclosing their illnesses to professionals. The resulting actions lead to poor health-seeking behaviour and underutilisation of existing formal health facilities. The ways that slum people use to communicate their feelings about illness, the type of confidants that they choose, and the supportive and unsupportive social and cultural interactions to which they are exposed have not yet been studied in the Indian context, which constitutes an important knowledge gap for Indian policymakers and practitioners alike...

Erin J Campbell, Nathan J Marchant
The last decade has seen major advances in neuroscience tools allowing us to selectively modulate cellular pathways in freely moving animals. Chemogenetic approaches such as Designer Receptors Exclusively Activated by Designer Drugs (DREADDs) permit the remote control of neuronal function by systemic drug administration. These approaches have dramatically advanced our understanding of the neural control of behaviour. Here we review the different techniques and genetic approaches available for the restriction of chemogenetic receptors to defined neuronal populations...

BACKGROUND: Development of collateral circulation after acute ischemic stroke is triggered by shear stress that occurs in pre-existing arterioles. Recently, sphingosine-1-phosphate receptor 1 (S1P1) on endothelial cells was reported to sense shear stress and transduce its signaling pathways. METHODS: BALB/c mice (n = 118) were subjected to permanent middle cerebral artery occlusion (pMCAO) or sham operation. We investigated the effect of an S1P1-selective agonist SEW2871 on leptomeningeal collateral arteries and neurological outcome after pMCAO...

The pathogenesis of recurrent Clostridium difficile infection (CDI) is still poorly understood. The risk of recurrence is approximately 20% after an initial CDI episode and dramatically increases with subsequent CDI recurrences. Several factors may play a role in recurrent CDI (rCDI), including conditions influencing germination, metabolic pathways that influence toxin production of C. difficile, and the microbiota composition offering protection against colonization and disease caused by C. difficile. Paradoxically, the currently recommended treatment for acute symptomatic CDI, i...

Drug resistance has been reported for every antimalarial in use highlighting the need for new strategies to protect the efficacy of therapeutics in development. We have previously shown that resistance can be suppressed with a population biology trap: by identifying situations where resistance to one compound confers hypersensitivity to another (collateral sensitivity), we can design combination therapies that not only kill the parasite, but also guide its evolution away from resistance. We applied this concept to the Plasmodium falciparum dihydroorotate dehydrogenase (PfDHODH) enzyme, a well validated antimalarial target with inhibitors in the development pipeline...

Cyanotic congenital heart disease presents an increased tendency to bleed in view of subtle coagulation defects. Airway bleeding can be particularly difficult to manage while maintaining an adequate ventilation. An isolated lung bleed with the exclusion of possible traumatic, medical and surgical causes of bleeding, should alert the attending anesthesiologist to the possibility of the collateral-related bleeding. Preoperative coil embolization remains an important initial management step in a case of tetralogy of Fallot (TOF) with major aortopulmonary collaterals...

Previous studies have shown the inhibitory effect of the in vitro application of copper sulfate on hippocampal long-term potentiation. While in vivo administration of copper did not affect spatial learning and memory. To find possible answers to this controversial issue, we evaluate the effect of different doses of copper sulfate on in vivo long-term potentiation, synaptic transmission, and paired-pulse behavior of CA1 pyramidal cells. Thirty-two male Wistar rats were divided into four groups: control, 5, 10, and 15 mg of copper sulfate...

Carotid artery disease (CAD) is a common cause of ischemic stroke with high rates of recurrence. Carotid endarterectomy (CEA) or carotid artery stenting (CAS) are highly recommended for the secondary prevention of symptomatic CAD during the first 14 days following the index event of transient ischemic attack or minor stroke. CEA or CAS may also be offered in selected cases with severe asymptomatic stenosis. Herein, we review the utility of neurosonology in the diagnosis and pre-/peri-interventional assessment of CAD patients who undergo carotid revascularization procedures...
