The role of melanin in agents of chromoblastomycosis in vivo still remains unclear. In this study, we addressed the question in a BALB/c mice infection model by using an albino mutant, which generated from a melanized meristematic mutant of F. monophora. The most severe clinical manifestations of infected mice were observed at 10-25 dpi (day post infection) and 7-15 dpi for melanized and albino strain, respectively. Histopathologic examination were similar in both groups at 15 dpi (acute infection phase), but not at 30 dpi (sustained infection phase) and 45 dpi (recovery phase)...

Connie R Shi, Vinod E Nambudiri
As the burdens of chronic disease rise in the United States, both undergraduate and graduate medical education must adapt to adequately equip future physicians with the skills to manage the increasingly complex health needs affecting the population. However, traditional models of undergraduate medical education (UME) have made focusing on chronic care education challenging. In this Invited Commentary, the authors advocate for strengthening UME based upon five approaches to engage trainees in learning about chronic care across both the preclinical and clinical phases of their education: (1) introducing chronic care in the preclinical years; (2) prioritizing chronic care education across all specialties; (3) maximizing the fourth year of medical school through a chronic care focus; (4) creating chronic disease-focused advanced clerkships; and (5) leveraging technology for education...

José Carlos Arévalo-Lorido, Juana Carretero-Gómez, Nicolás Roberto Robles
BACKGROUND: The relationship between serum uric acid (SUA) levels and stroke is controversial. The discrepancies in the results could be due to the uneven setting of comorbidity. It is known that hyperuricaemia increases in parallel with the decline in renal function; however, there are few studies that adjust for renal disease. AIM: To investigate the relationship between SUA levels in the acute phase of ischaemic stroke according to the presence or absence of chronic kidney disease and clinical outcomes during admission...

BACKGROUND: Single-phase CT angiography (CTA) forms the basis of hyperacute stroke imaging but many patients with terminal internal carotid artery (ICA) occlusion exhibit a pseudo-occlusion of the cervical ICA whereby a column of unopacified blood mimics a tandem cervical ICA lesion. We aimed to investigate the utility of a delayed phase acquisition to aid identification of a pseudo-occlusion and investigated the mechanism for this imaging artefact. METHODS: Thirteen patients with a pseudo-occlusion were compared with 13 patients without...

An urgent need exists for the development of more efficacious molecular strategies targeting non-melanoma skin cancer (NMSC), the most common malignancy worldwide. Inflammatory signaling downstream of Toll-like receptor 4 (TLR4) has been implicated in several forms of tumorigenesis, yet its role in solar UV-induced skin carcinogenesis remains undefined. We have previously shown in keratinocyte cell culture and SKH-1 mouse epidermis that topical application of the specific TLR4 antagonist resatorvid (TAK-242) blocks acute UV-induced AP-1 and NF-κB signaling, associated with downregulation of inflammatory mediators and MAP Kinase phosphorylation...

Sepsis is a common and often devastating medical emergency with a high mortality rate and, in many survivors, long-term morbidity. It is defined as the dysregulated host response to infection resulting in organ dysfunction, and its incidence is increasing as the population ages. However, it is a treatable and potentially reversible condition, especially if identified and treated promptly. A sound understanding of sepsis is crucial for optimal care. Although general guidelines are available for management, here we provide a foundation of understanding to encourage thoughtful, personalised management of sepsis during the acute phase...

BACKGROUND AND AIMS: Prebiotics such as Arabinoxylooligosaccharides (AXOS) are non-digestible, fermentable food ingredients stimulating growth/activity of colonic bacteria with enhanced carbohydrates fermentation (CF) in humans. The migrating motor complex (MMC) of the gastrointestinal tract has been recently identified as an important hunger signal, but no data are available yet on the role of acute CF on MMC activity and related hunger ratings. Thus, we aimed to study the effect of acute AXOS CF on MMC and hunger in humans...

Acute promyelocytic leukemia (APL) remains a challenge to cure due to the side effects of cytotoxic chemotherapy and drug resistance. The present study demonstrated that vernodalol, an active compound isolated from Centratherum anthelminticum, suppresses APL cell proliferation and induces cell cycle arrest in the G2/M phase through the upregulation of p21 and cell division cycle 25. In addition, vernodalol induced cellular apoptosis via the mitochondrial pathway as observed by the cleavage of caspase-9 as well as the release of cytochrome c and Smac/DIABLO into the cytosol...

Chloroquine (CQ) has been confirmed to exhibit antitumor effects on different types of cancer cell, but whether it exerts the same effect on acute promyelocytic leukemia (APL) cells remains to be confirmed. In the present study, the effects of various concentrations of CQ on the growth, apoptosis and cell cycle distribution of NB4 cells, as well as the potential mechanisms underlying these effects, were examined. The combined effect of CQ and arsenic trioxide (ATO) on the growth of NB4 cells was also determined...

Lactation impairment in sows is a frequent and significant clinical problem. Due to a complex aetiopathogenesis, early diagnosis of postpartum dysgalactia syndrome (PDS) is difficult and so far has usually been based on physical examination performed in the first days after farrowing. To date no data have been provided on the diagnostic usefulness of acute phase proteins (APP) in early diagnosis of peripartum disorders, including lactation disorders in sows. This study aimed at measuring the serum concentration of selected APP (C-reactive protein (CRP), haptoglobin (Hp), serum amyloid A (SAA) and pig major acute phase protein (Pig-MAP)) in sows with physiological and pathological course of the peripartum period and at evaluating the possibility of utilising the studied markers in the early diagnosis of lactation disorders...

Zikavirus (ZV) is a flavivirus transmitted by Aedes mosquitoes' bites. Sexual transmission is possible. Common ZV infection is asymptomatic or associates flu-like signs. Guillain-Barre syndrome following ZV infection is rare. Foetal infection, during the first trimester of pregnancy especially, can lead to severe neurological troubles. Diagnosis relies on blood and urine RT-PCR during the acute phase, and serology later in the disease. ELISA assays false positives are reported among patients infected with another flavivirus, whereas sero-neutralization is more specific...
