Different rotifer stains exhibited remarkably morphological differences which could not be eliminated under laboratory conditions. In the present study, we hypothesized that predation pressure and pollution might be two forces driving morphological differentiation of rotifer. To test this hypothesis, rotifers (Brachionus calyciflorus) belonging to two sibling species were collected from three special lakes (with coal ash pollution, high predation pressure or neither) and cultured for more than three months to investigate their potential differentiation in morphology...

The green sulfur bacteria (Chlorobiaceae) are anaerobes that use electrons from reduced sulfur compounds (sulfide, S(0), and thiosulfate) as electron donors for photoautotrophic growth. Chlorobaculum tepidum, the model system for the Chlorobiaceae, both produces and consumes extracellular S(0) globules depending on the availability of sulfide in the environment. These physiological changes imply significant changes in gene regulation, which has been observed when sulfide is added to Cba. tepidum growing on thiosulfate...

Interactions between photoautotrophic and heterotrophic microorganisms are central to the marine microbial ecosystem. Lab cultures of one of the dominant marine photoautotrophs, Synechococcus, have historically been difficult to render axenic, presumably because these bacteria depend upon other organisms to grow in these conditions. These tight associations between Synechococcus and heterotrophic bacteria represent a good, relevant system to study interspecies interactions. Ten individual Synechococcus strains, isolated from eutrophic and oligotrophic waters, were chosen for investigation...

The important role of microfilaria (worms) in human and animal disease remains an area of key disagreement between the naturopathic and allopathic physicians. While microfilaria infections are rampart in undeveloped countries, they rarely rise to identification as a cause of disease in Western countries. New research studies in the diagnosis and treatment of SIBO (Small Intestinal Bacterial Overgrowth) and (IBD) Inflammatory Bowel Diseases of ulcerative colitis, Crohn's Disease and microcytic colitis may make both sides equally correct...

PURPOSE: One factor that can contribute to severe bone loss after transplantation is the direct action of immunosuppressants on bone cells. The aim of this work was to study the effects of cyclosporine (CsA), tacrolimus (FK-506), and rapamycin (RAPA) on the release of three local factors directly implicated in bone-remodeling regulation and apoptosis of human osteoblasts: interleukin (IL)-6, osteoprotegerin, and receptor activator of nuclear factor κβ (RANKL). BASIC PROCEDURES: Human osteoblasts were obtained from five different patients who underwent orthopedic surgery...

Over the past decade, Structure from Motion (SfM) has increasingly been used as a means of digital preservation and for documenting archaeological excavations, architecture, and cultural material. However, few studies have tapped the potential of using SfM to document and analyze taphonomic processes affecting burials for forensic sciences purposes. This project utilizes SfM models to elucidate specific post-depositional events that affected a series of three human cadavers deposited at the South East Texas Applied Forensic Science Facility (STAFS)...

What makes a researcher wise? At least for the field of psychology, I argue that the two main characteristics of scholarly wisdom are a desire to understand, rather than to be right, and an orientation toward ethical values. These characteristics do not necessarily produce the highest levels of academic success. Because wisdom is partly context dependent, the actual wisdom of our scientific output could be increased by making some changes to our publication and evaluation culture-changes that might benefit our field and even the world around us...

BACKGROUND: Cutaneous leishmaniasis, caused by a parasitic infection, is considered one of the most serious skin diseases in many low- and middle-income countries. Old World cutaneous leishmaniasis (OWCL) is caused by species found in Africa, Asia, the Middle East, the Mediterranean, and India. The most commonly prescribed treatments are antimonials, but other drugs have been used with varying success. As OWCL tends to heal spontaneously, it is necessary to justify the use of systemic and topical treatments...

AIMS AND OBJECTIVES: To understand women's perspectives about the trajectory from first bodily changes to diagnosis. BACKGROUND: With endometrial cancer, as with all gynaecological cancers, early diagnosis is key to successful outcomes. However, women do not always seek clinical advice early. Previously, this gap has been referred to as a 'delay', blamed on fear or refusal to acknowledge symptoms. METHODS: A qualitative research project which involved face-to-face interviews with 16 women who had presented with symptoms of endometrial cancer...

Bioreactors are essential cell and tissue culture tools that allow the introduction of biophysical signals into in vitro cultures. One major limitation is the need to interrupt experiments and sacrifice samples at certain time points for analyses. To address this issue, we designed a bioreactor that combines high-resolution contact-free imaging and continuous flow in a closed system that is compatible with various types of microscopes. The high-throughput fluid flow bioreactor was combined with two-photon fluorescence lifetime imaging microscopy (2P-FLIM) and validated...

RATIONALE, AIMS, AND OBJECTIVES: Previous studies have shown a lack of engagement in the reporting process. There is limited evidence about whether attitudes and behaviours of doctors in the UK towards incident reporting have changed following the events at Mid Staffordshire National Health Service Foundation Trust and the recommendations that followed. We conducted a relatively large survey of doctors, aiming to assess whether doctors recognised incidents and reported them accordingly, along with their behaviours towards reporting and their suggestions of how incident reporting may be improved...

In the pond culture of juvenile Eriocheir sinensis, various factors have frequently led to a high rate of autotomy and limb impairments. This study evaluated the differential effects of cheliped loss with autotomy and ablation on the short-term cellular and biochemical parameters of juvenile E. sinensis. In this study, compared with the crabs before treatment, the total hemocyte counts (THC), granulocyte counts (GC), hemocyte agglutination, phosphatase activity and glucose metabolism levels were significantly increased, while hyalinocyte counts (HC) and total antioxidant capacity (T-AOC) were significantly decreased within 3 h...

BACKGROUND: Dendritic Cell-Specific Transmembrane Protein (DC-STAMP) is involved in osteoclastogenesis with a key role in mononucleated osteoclasts fusion. We reported in patients with Paget's disease of bone (PDB) a rare variant (rs62620995) in the TM7SF4 gene, encoding for DC-STAMP, which changes a highly conserved amino acid, possibly damaging according to in silico predictions. This study aimed at determining the functional effects of this variant on osteoclast phenotype in PDB. METHODS: Fifty ml of peripheral blood were collected in pagetic patients carrier of this variant (n = 4) or not (n = 4) and healthy controls (n = 4)...

With recent technologies making it possible for commercial scale closed life-cycle aquaculture production of spiny lobster (Panulirus ornatus) comes a strong impetus to further understand aspects of lobster health. The gut microbiome plays a crucial role in host health, affecting growth, digestion, immune responses and pathogen resistance. Herein we characterise and compare gut microbiomes across different developmental stages (6-7 d post-emergence [dpe], 52 dpe and 13 months post-emergence [mpe]) and gut regions (foregut, midgut and hindgut) of cultured P...

Obstructive sleep apnea hypopnea syndrome (OSAHS) is associated with glucose intolerance, insulin resistance and type 2 diabetes mellitus (T2DM). Although several studies have revealed that intermittent hypoxia (IH) in OSAHS may further aggravate pancreatic β cell damage and promote the evolution of type 2 diabetes (T2DM) by increasing oxidative stress, the underlying mechanisms are unclear. Honokiol, a potent radical scavenger, has been demonstrated to ameliorate oxidative stress in many cases. The present study aimed to explore the potential mechanism of IH and diabetes synergistically damage and destruct the pancreatic β cell, examine the effects of honokiol on ameliorating pancreatic β cell injury in this context and explore the mechanism of such effects...
