This study evaluated the thrombotic and oxidative responses induced by ZIKV in cardiac cells and immunocompetent mice. Cardiac (H9c2) and vascular smooth muscle (A7r5) cell lines were infected with ZIKV and analyzed for viral replication, cytopathic effects and oxidative stress.

The Minimal Clinically Important Difference in Allergen Immunotherapy: An Evidence-Based Approach.

Background: Regulatory authorities recommend a combination of symptom and medication scores during the grass pollen season as a primary endpoint for Phase III allergen immunotherapy (AIT) trials targeting allergic rhinoconjunctivitis. However, many composite primary endpoint scales exist; none are validated, nor do they have a well-justified minimal clinically important difference (MCID).

Methods: Direct patient feedback from 1071 grass-allergic patients was obtained to determine the minimally relevant improvement in allergic symptoms and translated into an MCID for the EAACI recommended CSMS.

IxsS7: A novel biomarker for Ixodes scapularis tick bite exposure in humans.

Ixodes scapularis is a primary vector of several important tick-borne pathogens including Borrelia burgdorferi sensu lato, the causative bacterial genospecies complex of Lyme disease, Babesia microti, Anaplasma phagocytophilum, Borrelia miyamotoi, Ehrlichia muris eauclarensis, and Powassan virus. Salivary compounds secreted by I. scapularis during blood feeding are immunogenic and can elicit robust antibody responses in humans which can potentially be leveraged as surrogate markers of prior tick bite exposure.

In this work, applying shotgun proteomics we revealed the differential ZIKV infection proteome in Vero cells, a non-neural cell model.

Growth hormone and gonadotropin association: A case report of full-term pregnancy in a patient with panhypopituitarism.

Hypopituitarism is the inability of the anterior pituitary gland to properly supply the hormone levels. When this disease affects all the hormones produced by the anterior pituitary, it is called panhypopituitarism (PHP). Since pituitary-derived hormones directly influence fertility, often the assisted reproduction techniques are the only option to PHP women have a full-term pregnancy.

Enhancing food security while reducing environmental impacts: Life cycle assessment of cultivation-irrigation systems and yield gap closure in paddy fields.

Enhancing food and water security is crucial, not only by preventing additional burdens on the environment but also by significantly mitigating existing environmental challenges. Dry direct-seeding of rice (DDSR) and yield gap (YG) reduction are effective in enhancing water productivity (WP) and food production. However, their related environmental impacts (EI) have received less attention.

Ixochymostatin, a trypsin inhibitor-like (TIL) protein from Ixodes scapularis, inhibits chymase and impairs vascular permeability.

Ticks obtain a blood meal by lacerating small blood vessels and ingesting the blood that flows to the feeding site, which triggers various host responses. However, ticks face the challenge of wound healing, a process involving hemostasis, inflammation, cell proliferation and migration, and remodeling, hindering blood acquisition. To overcome these obstacles, tick salivary glands produce an array of bioactive molecules.

Metabolic Reprogramming of Exposed to Serum and Its Potential Implications in Host Immune System Evasion and Resistance.

The aim of this study was to identify, using proteomics, the molecular alterations caused by human serum exposure to ACH2. The analysis was performed under two different conditions, native serum from healthy donors and heat-inactivated serum (to inactivate the complement system), and at two different times, after 1 and 4 h of serum exposure. More than 1,000 bacterial proteins were identified at each time point.

Preconditioning by Moderate-Intensity Exercise Prevents Gentamicin-Induced Acute Kidney Injury.

Methods: Alt a 1-RA complex formation was analyzed in silico and in vitro. PBMCs from Alternaria-allergic donors were stimulated with Alt a 1 complexed with RA (holo-Alt a 1) or empty apo-Alt a 1 and analyzed for cytokine production and CD marker expression.

Exploring the transcriptome of immature stages of Ornithodoros hermsi, the soft-tick vector of tick-borne relapsing fever.

Blood-feeding behavior has independently evolved in arthropods multiple times. Unlike hard ticks, soft ticks employ a rapid-feeding strategy for hematophagy, and there are comparatively limited studies on the transcriptomes of these organisms. This study investigates the soft tick Ornithodoros hermsi, conducting histopathological examinations at bitten skin sites and tick whole-body transcriptomic analyses across various developmental and feeding stages, including larvae, 1st-nymphal, and 2nd-nymphal stages.

Angiotensin II - AT1 receptor signalling regulates the plasminogen-plasmin system in human stromal endometrial cells increasing extracellular matrix degradation, cell migration and inducing a proinflammatory profile.

The pivotal role of human endometrial stromal cells (hESCs) in the development of endometriosis lies in their ability to adopt a pro-invasive and proinflammatory profile upon migration to areas outside the uterus. However, the molecular mechanisms involved in these events remain unclear. In this study, we investigated how angiotensin II (Ang II) affects the plasminogen-plasmin system in hESCs, and the mechanisms underlying cell proliferation, migration, matrix degradation, and inflammation.

Digitally-enabled, person-centred care (PCC) in allergen immunotherapy: An ARIA-EAACI Position Paper.
