BACKGROUND: Debate around the value of laboratory tests in establishing the diagnosis of acute appendicitis (AA) still continues. This prospective study aimed to investigate the changes in mean platelet volume (MPV), platelet distribution width (PDW), and red cell distribution width (RDW) with the diagnosis of acute appendicitis. METHOD: 200 patients who underwent emergency appendectomy were included. According to postoperative histology, patients were divided into three groups: acute non-complicated, acute complicated appendicitis (positive appendicectomy groups), and negative appendectomy group...

Little attention has been paid to the impact of wastewater generated by mining activities on fluoride. In this study, we evaluated the hematology responses of common South American toad Rhinella arenarum inhabiting natural and artificial environments associated with a fluorite mine from central Argentina. We analyzed three sampling stations associated with the fluorite mine: (I) Los Cerros Negros stream (CN), which runs on granitic rock with a high fluorite content; (II) Los Vallecitos stream (LV), which runs on metamorphic rock with low fluorite content; and (III) artificial decantation ponds (DP) containing sediments produced by fluorite flotation process...

Toxoplasmosis is an important cause of enhancing brain lesions in patients with acquired immunodeficiency syndrome (AIDS), and it is typically associated with low CD4-lymphocyte counts. Extensive toxoplasma encephalitis when the CD4-lymphocyte count is above 100 cells/µl is unusual. Cavitary lung lesions are also not typically associated with toxoplasmosis. Here, we present a case of toxoplasmosis associated with extensive brain masses and cavitary lung lesions, both of which improved with directed toxoplasmosis therapy, in an AIDS patient with a CD4 cell count of 120 cells/µl...

BACKGROUND: Patients with Mycobacterium avium complex (MAC) lung disease (LD) have a heterogeneous prognosis. This study aimed to develop and validate a prognostic scoring model for these patients using independent risk factors for survival. METHODS: We retrospectively analyzed the data of patients with MAC-LD from two hospitals (cohort 1, n = 368; cohort 2, n = 118). Cohort 1 was evaluated using a multivariate Cox proportional hazards model to identify independent risk factors for overall survival (OS)...

BACKGROUND: P21-activated kinase 1 (PAK1) stimulates growth and metastasis of colorectal cancer (CRC) through activation of multiple signalling pathways. Up-regulation of CRC stem cell markers by PAK1 also contributes to the resistance of CRC to 5-fluorouracil. The aim of this study was to investigate the effect of PAK1 depletion and inhibition on the immune system and on intestinal tumour formation in APC(∆14/+) mice. METHODS: The PAK1 KO APC(∆14/+) mice were generated by cross-breeding of PAK1 KO mice with APC(∆14/+) mice...

Exposure to stress is known to cause hepatic iron dysregulation, but the relationship between prolonged stress and liver iron metabolism is not yet fully understood. Thirty 13-week-old female Sprague-Dawley rats were randomly divided into two groups, as follows: the control group (saline-injection) and the dexamethasone group (Dexamethasone (Dex)-injection 0.1 mg/kg/day). After the 21-day stress trial, the results showed that chronic Dex administration not only impaired serum corticosterone (p = 0.00) and interleukin-6 (IL-6) (p = 0...

BACKGROUND: Immunosuppression is common even in the early stage of severe sepsis. Interleukin-10 (IL-10) secretion and lymphocyte exhaustion are the main features of sepsis-induced immunosuppression. However, the relationship between IL-10 and the lymphocyte is still unclear. We investigated if IL-10/lymphocyte ratio (IL10LCR) were associated with mortality in severe septic patients. METHODS: Adult patients with severe sepsis admitted to ICU of the First Affiliated Hospital of Guangzhou Medical University were identified from October 2012 to August 2013...

The cell composition of bronchoalveolar lavage fluid (BAL) is an important indicator of airway inflammation. It is commonly determined by cytocentrifuging leukocytes on slides, then staining, identifying, and counting them as eosinophils, neutrophils, macrophages, or lymphocytes according to morphological criteria under light microscopy, where it is not always easy to distinguish macrophages from lymphocytes. We describe here a one-step, easy-to-use, and easy-to-customize 8-color flow cytometric method for performing differential cell count and comparing it to morphological counts on stained cytospins...

Enterovirus D68 has been associated with a poliomyelitis-like illness, notably during an outbreak in 2014, and particularly affecting children in the USA. We report a case of acute segmental flaccid paralysis with respiratory involvement in an adult in the UK, with enterovirus D68 detected in a sputum sample. MR imaging of cervical spinal cord showed a longitudinally extensive T2 hyperintensity in the anterior cord. Cerebrospinal fluid showed an elevated white cell count, predominantly lymphocytic, with otherwise normal constituents and negative viral PCRs...

Introduction: The prognostic significance of neutrophil-to-lymphocyte ratio (NLR), derived-neutrophil-to-lymphocyte ratio (d-NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) have been shown in many diseases. To the best of our knowledge, there is no published report evaluation of those parameters in acute exacerbation of chronic obstructive pulmonary disease (AECOPD). The aims of this study are to evaluate the parameters in predicting in-hospital mortality in patients with AECOPD...

Black cohosh rhizome, available as a dietary supplement, is most commonly marketed as a remedy for dysmenorrhea and menopausal symptoms. A previous subchronic toxicity study of black cohosh dried ethanolic extract (BCE) in female mice revealed a dose-dependent ineffective erythropoiesis with a macrocytosis consistent with the condition known as megaloblastic anemia. The purpose of this study was to investigate potential mechanisms by which BCE induces these particular hematological changes. B6C3F1/N female mice (32/group) were exposed by gavage to vehicle or 1,000 mg/kg BCE for 92 days...

Nowadays, many biological data are acquired via images. In this article, we study the pathological images scanned from 205 patients with lung cancer with the goal to find out the relationship between the survival time and the spatial distribution of different types of cells, including lymphocyte, stroma, and tumor cells. Toward this goal, we model the spatial distribution of different types of cells using a modified Potts model for which the parameters represent interactions between different types of cells and estimate the parameters of the Potts model using the double Metropolis-Hastings algorithm...

While haematological variation is well known in birds, variation in avian breeds (distinct morphotypes of the same species) remains unexplored. Poultry breeds, in particular, may show interesting evolutionary patterns and economically-relevant physiological differences. We performed a comparative examination of blood cellular composition in five chicken (Gallus gallus domesticus) breeds: Araucana, Booted bantam, Czech, Minorca and Rosecomb bantam. In standard-environment-reared hens whole-blood flow cytometry revealed remarkable differences in most erythrocyte- and leukocyte-related parameters...

The vast burden of cryptococcal meningitis occurs in immunosuppressed patients, driven by HIV, and is caused by Cryptococcus neoformans var. grubii. We previously reported cryptococcal meningitis in Vietnam arising atypically in HIV uninfected, apparently immunocompetent patients, caused by a single amplified fragment length polymorphism (AFLP) cluster of C. neoformans var. grubii (VNIγ). This variant was less common in HIV infected individuals; it remains unclear why this lineage is associated with apparently immunocompetent patients...
