In 1981, psychologist James Flynn noticed that IQ scores had risen streadily over nearly a century a staggering difference of 18 points over two generations. After a careful analysis, he concluded the cause to be culture. Society had become more intelligent-come to grips with bigger, more abstract ideas over time-and had made people smarter. This observation, combined with solid evidence that IQ scores are also not fixed within an individual, neatly dispels the idea of intelligence being an innate and fixed entity...

Inefficient carbon metabolism is a relevant issue during the culture of mammalian cells for the production of biopharmaceuticals. Therefore, cell engineering strategies to improve the metabolic and growth performance of cell lines are needed. The expression of Vitreoscilla stercoraria hemoglobin (VHb) has been shown to significantly reduce overflow metabolism and improve the aerobic growth of bacteria. However, the effects of VHb on mammalian cells have been rarely studied. Here, the impact of VHb on growth and lactate accumulation during CHO-K1 cell culture was investigated...

The discovery of chemotherapeutic agents for the treatment of cancer commonly uses cell proliferation assays in which cells grow as two-dimensional (2D) monolayers. Compounds identified using 2D monolayer assays often fail to advance during clinical development, most likely because these assays do not reproduce the cellular complexity of tumors and their microenvironment in vivo. The use of three-dimensional (3D) cellular systems have been explored as enabling more predictive in vitro tumor models for drug discovery...

Single-walled carbon nanotubes (SWCNTs) are thoroughly purified and dispersed in an aqueous solution of high molecular weight poly-L-lysine (pLlys). Human intestinal epithelial Caco-2/TC7 cells are incubated with the SWCNT dispersions in pLlys, and their effects on cell viability are studied by image flow cytometry. No significant changes are observed in the cell culture wells up to pLlys concentrations of 10 μg ml(-1). However, high mortality is detected at pLlys concentrations of 100 μg ml(-1). The presence of oxygen-free SWCNTs does not modify the effects of pLlys on cell cultures at any of the tested concentrations (≤1 μg ml(-1))...

INTRODUCTION: Considerable advocacy, funding, training, and technical support have been provided to South Asian countries to strengthen One Health (OH) collaborative approaches for controlling diseases with global human pandemic potential since the early 2000s. It is essential that the OH approach continues to be strengthened given South Asia is a hot spot for emerging and endemic zoonotic diseases. The objectives of this article are to describe OH research and training and capacity building activities and the important developments in government support for OH in these countries to identify current achievements and gaps...

BACKGROUND: Mesenchymal stem/multipotent stromal cells (MSCs) contribute to tissue repair but are challenged during wound healing when the blood supply is disrupted, thereby limiting nutrient delivery. Survival mechanisms against 'starvation' include autophagy, which we previously found to enhance differentiation efficiency. MSC response to models of in vitro nutrient deprivation are of great interest for improving MSC survival and therapeutic efficacy; however, the rate-limiting nutrients are unknown...

Human immunodeficiency virus (HIV) epidemic has undoubtedly increased the incidence of tuberculosis (TB) globally, posing a formidable global health challenge affecting 1.2 million cases. Pulmonary TB assumes utmost significance in the programmatic perspective as it is readily transmissible as well as easily diagnosable. HIV complicates every aspect of pulmonary tuberculosis from diagnosis to treatment, demanding a different approach to effectively tackle both the diseases. In order to control these converging epidemics, it is important to diagnose early, initiate appropriate therapy for both infections, prevent transmission and administer preventive therapy...

BACKGROUND: Previous studies with BIT225 (N-carbamimidoyl-5-(1-methyl-1H-pyrazol-4-yl)-2-naphthamide) have demonstrated a unique antiviral activity that blocks the release of HIV-1 from monocyte-derived macrophages (MDM). Antagonising the ion channel formed by HIV-1 Vpu, BIT225 preferentially targets de novo intracellular virus produced in 'virus-containing compartments' of MDM. In primary infections, dendritic cells (DC) are one of the first cells infected by HIV-1 and can transfer virus to more permissive CD4(+) T cells, making these cells an important target for novel antiviral therapies...

A significant target for radiation-induced effects is the microvascular system, which is critical to healthy tissue function and its pathology is linked to disrupted endothelial barrier function. Low-linear energy transfer (LET) ionizing radiation is a source of noncancer pathologies in humans and little is known about the early events that could initiate subsequent diseases. However, it is well known that gamma radiation causes a very early disruption of the endothelial barrier at doses below those required for cytotoxic effects...

Transforming growth factor (TGF)-β1 is an important cytokine in airway remodeling in asthma. However, results of studies focusing on the effect of TGFβ1 on proliferation of airway smooth muscle cells (ASMCs) are controversial. This study aimed to elucidate the role of TGFβ1 signaling in the proliferation of ASMCs by establishing an allergic model that mimics airway remodeling in chronic asthma and cell culture. Cell proliferation was detected by viable cell counting and Cell Counting Kit (CCK)-8 analysis...

The purpose of this descriptive qualitative study is to explore the perceptions and experiences that mental health service users (n = 10) and healthcare professionals (n = 32) have regarding the use of gamification in mental health care. Data was gathered by interviews. The mental health service users described promoting and retarding factors in the use of gamification, while professionals described the requirements for using gamification and changes occurring in the work culture. Additional research is needed on how game-playing elements could be integrated as a systematic part of mental health practice and how the digital skills of professionals could be effectively developed...

OBJECTIVE: Corneal ulcers are commonly encountered in pinnipeds. Prolonged oral antibiotics and topical ophthalmic solutions may not be practical to administer, and novel treatment techniques are desired. Thermodynamic gels are a potential solution because they hold antimicrobials at the site of injection, slowly releasing drug. This study investigated the clinical efficacy of antibiotic-impregnated poloxamer gel in management of corneal ulceration.

α-Tubulin C-terminus undergoes post-translational, cyclic tyrosination/detyrosination, and L-Phenylalanine (Phe) can be incorporated in place of tyrosine. Using cultured mouse brain-derived cells and an antibody specific to Phe-tubulin, we showed that: (i) Phe incorporation into tubulin is reversible; (ii) such incorporation is not due to de novo synthesis; (iii) the proportion of modified tubulin is significant; (iv) Phe incorporation reduces cell proliferation without affecting cell viability; (v) the rate of neurite retraction declines as level of C-terminal Phe incorporation increases; (vi) this inhibitory effect of Phe on neurite retraction is blocked by the co-presence of tyrosine; (vii) microtubule dynamics is reduced when Phe-tubulin level in cells is high as a result of exogenous Phe addition and returns to normal values when Phe is removed; moreover, microtubule dynamics is also reduced when Phe-tubulin is expressed (plasmid transfection)...

In vitro Omics analysis (i.e. transcriptome) is suggested to predict in vivo toxicity and adverse effects in humans, although the causal link between high-throughput data and effects in vivo is not easily established. Indeed, the chemical-organism interaction can involve processes, such as adaptation, not established in cell cultures. Starting from this consideration we investigate the transcriptomic response of immortalized thyrocytes to ethylenthiourea and chlorpyrifos. In vitro data revealed specific and common genes/mechanisms of toxicity, controlling the proliferation/survival of the thyrocytes and unrelated hematopoietic cell lineages...

Investigations of cellular processes initiated by volatile organic compounds (VOCs) are limited when modelling realistic long-term exposure scenarios at low concentrations. Exposure to indoor VOCs is associated with a range of adverse effects, but data on molecular changes at regulatory threshold limits are lacking. Activity analysis of VOC in vitro can be a valuable complement to inhalation toxicological evaluations. We developed an exposure platform that generates a stable VOC atmosphere and allows the exposure of cells for longer periods...

Birt-Hogg-Dubé syndrome (BHDS) is an autosomal dominant inherited disorder caused by germline mutations in the FLCN gene, and characterized by skin fibrofolliculomas, multiple lung cysts, spontaneous pneumothorax, and renal neoplasms. Pulmonary manifestations frequently develop earlier than other organ involvements, prompting a diagnosis of BHDS However, the mechanism of lung cyst formation and pathogenesis of pneumothorax have not yet been clarified. Fibroblasts were isolated from lung tissues obtained from patients with BHDS (n = 12) and lung cancer (n = 10) as controls...

OBJECTIVE: Leishmaniasis is caused by an obligate intracellular protozoa belonging to Leishmania genus and listed among major tropical diseases by WHO. Because of the high costs, toxicity, and adverse effects of routinely used compounds in the treatment, alternative treatment and vaccine studies are underway. An effective vaccine has not been developed to date. In this study, we aimed to clone one of the most promising DNA vaccine candidates: the homolog-activated C kinase (LACK) gene of Leishmania infantum...

The aim of this study was to evaluate the effect of co-culture of denuded oocytes with cumulus cells (CC) or cumulus-oocyte complexes (COCs) on in vitro maturation (IVM) and in vitro fertilization (IVF). Immature oocytes were collected from ovaries of domestic cats following a routine ovariectomy. Oocytes were matured in vitro for 24 hr within four groups: (i) denuded oocytes (DO), (ii) DO co-cultured with CC, (iii) DO co-cultured with COC and (iv) COC as a control group. In further experiments, COCs were matured in vitro for 24 hr, and then, oocytes were randomly divided into four groups as previously described and fertilized in vitro...

BACKGROUND: Only eight women out of one hundred diagnosed with ovarian epithelial cancers, which progressed to the clinical stage IV, survive 10 years. First line therapies: surgery, chemotherapy, and radiation therapy inflict very serious iatrogenic consequences. Passive immunotherapy of ovarian cancers offers only low efficacy. Prophylactic and therapeutic vaccines for ovarian cancers are not available. Interestingly, prophylactic vaccines for Hepatitis B Viruses (HBV) are very effective...

Iron-chelating activity of synthesized spirocyclic hydroxamic acids, their toxicity, and effects on mitochondrial function were studied using primary culture of cerebral cortical neurons from newborn rats. All tested compounds effectively chelated Fe(II) ions. Activity of spirocyclic hydroxamic acids more strictly depended on the structure their piperidine, but not imidazolidine fragment. All compounds were non-toxic for normal neuronal culture.
