Jet quenching has been used successfully as a hard probe to study properties of the quark-gluon plasma (QGP) in high-energy heavy-ion collisions at both the relativistic heavy-ion collider and the large hadron collider. We will review recent progresses in theoretical and phenomenological studies of jet quenching with jet transport models. Special emphasis is given to effects of jet-induced medium response on a wide variety of experimental observables and their implications on extracting transport properties of the QGP in heavy-ion collisions.

To compare effectiveness and safety of initial antiretroviral therapy (ART) among premenopausal and postmenopausal women living with HIV aged 45-60 years from the cohort of the Spanish HIV/AIDS Research Network (CoRIS) who initiated ART between 2004 and 2015.

Multivariable regression models were used to compare post- versus premenopausal women regarding viral suppression (≤50 copies/ml), change in CD4

T-cell count and time to treatment change (TC) at 48 and 96 weeks after ART initiation.

Among 230 women, 154 (67%) were premenopausal at ART initiation. The most frequent initial regimen was tenofovir disoproxil fumarate/emtricitabine/efavirenz prescribed in 49 (32%) premenopausal and 22 (29%) postmenopausal women. The proportion of TC was 35.7% and 30.3% at 48 weeks and 51.3% and 47.4% at 96 weeks, for pre- and postmenopausal women, respectively. There were no significant differences in CD4

T-cell count changes from ART initiation, viral load suppression, time to TC or reason for TC between both groups. The main reason for TC was occurrence of an adverse event, followed by simplification, in both groups.

ART effectiveness and safety did not differ significantly between pre- and postmenopausal women.

We aim to define the dynamic interplay between neurovascular-specific comorbidities and in-hospital complications on outcomes (functional outcome and mortality), length of stay (LOS), and cost of hospital stay.

The 2012-2015 National Inpatient Sample (NIS) was queried for intracranial aneurysm treatment after subarachnoid hemorrhage using International Classification of Diseases, Ninth Revision codes. Neurovascular comorbidity index (NCI) was aggregated. NIS-Subarachnoid Hemorrhage Severity Score (NIS-SSS) was used as a Hunt-Hess grade proxy. In-hospital complications were medical complications, surgical complications, seizures, and cerebral vasospasm. Outcomes were functional outcome (modified Rankin Scale [mRS]-equivalent measure), in-hospital mortality, LOS, and cost. Multivariable logistic regression models were built for mRS equivalent and in-hospital mortality. Multivariable linear regression models in log scale were built for LOS and cost.

A total of 5353 patients were included. The median NCI waorbidities more so than those with low or high comorbidities.

Neurovascular comorbidities are the primary driver of poor mRS equivalent outcome, in-hospital mortality, higher LOS, and higher cost after ruptured intracranial aneurysm procedural treatment. The conditional event of complication influences patients with moderate comorbidities more so than those with low or high comorbidities.Article highlight based on "SNW1 interacts with IKKγ to positively regulate antiviral innate immune responses against influenza A virus infection" by Qiao et al.Accumulating evidence suggests that high serum uric acid (UA) is associated with left ventricular (LV) dysfunction. Although xanthine oxidase (XO) activation is a critical regulatory mechanism of the terminal step in ATP and purine degradation, the pathophysiological role of cardiac tissue XO in LV dysfunction remains unclear. We herein investigated the role and functional significance of tissue XO activity in doxorubicin-induced cardiotoxicity. Either doxorubicin (10 mg/kg) or vehicle was intraperitonially administered in a single injection to mice. Mice were treated with or without oral XO-inhibitors (febuxostat 3 mg/kg/day or topiroxostat 5 mg/kg/day) for 8 days starting 24 h before doxorubicin injection. Cardiac tissue XO activity measured by a highly sensitive assay with liquid chromatography/mass spectrometry and cardiac UA content were significantly increased in doxorubicin-treated mice at day 7 and dramatically reduced by XO-inhibitors. Accordingly, XO-inhibitors substantially improved LV ejection fraction (assessed by echocardiography) and LV developed pressure (assessed by ex vivo Langendorff heart perfusion) impaired by doxorubicin administration. Cytidine 5′-triphosphate This was associated with an increase in XO-derived hydrogen peroxide production with concomitant upregulation of apoptotic and ferroptotic pathways, all of which were reduced by XO-inhibitors. Furthermore, metabolome analyses revealed enhanced purine metabolism in doxorubicin-treated hearts, and XO-inhibitors suppressed the serial metabolic reaction of hypoxanthine-xanthine-UA, the paths of ATP and purine degradation. In summary, doxorubicin administration induces cardiac tissue XO activation associated with impaired LV function. XO-inhibitors attenuate doxorubicin-induced cardiotoxicity through inhibition of XO-derived oxidative stress and cell death signals as well as the maintenance of cardiac energy metabolism associated with modulation of the purine metabolic pathway.Major surface protein 1 alpha (Msp1α) is a stable genetic marker for identifying Anaplasma marginale. Our aims were to investigate the genetic diversity of A. marginale based on microsatellites and tandem repeats of the msp1α gene and to determine the phylogenetic relationships among six isolates obtained from 63 dairy cows positive for the pathogen from Turkey and from strains worldwide. Msp1α microsatellite analysis revealed infection with three genotypes (B, C, G). Genotype B was found in cows held in an intensive management system, while genotypes C and G were found in grazing cows. Microsatellite sequences produced SD-ATG distances of 19 and 23 nucleotides, with 23 nucleotides predominating, showing high infection potential. Fourteen different tandem repeats of A. marginale were found in the samples, and four msp1α gene repeats designated Tr4, Tr5, Tr6 and Tr7 were newly described. The majority of A. marginale isolates exhibited more than three Msp1a tandem repeats, with a maximum of seven. The Msp1a tandem repeats α-73-73-73-73-73-73 were commonly observed in intensively managed cows.
