At the end of 2010, almost all reservoirs in Taiwan have sedimentation problem. Sedimentation in major reservoirs, such as Wushoh reservoir, had reached 63.73% of its storage capacity in 2009, and must undergo dredging. However, agencies responsible for the final processing stages of reservoir sediments failed to come up with a breakthrough. Limitations established by environmental protection laws also hindered proper dredging of the reservoirs. Hence, further investigation was required for solidifying and reusing reservoir sediments. This research focused on the reuse of Wushoh reservoir sedi

Streszczenie:

Bacteriophages, as the name “bacteria-eater” suggests, are viruses that infect bacteria. Bacteriophages, often abbreviated as “phages,” have receptors that bind to specific bacterial species, thus there are many types of bacteriophages. Once a phage interacts with its target bacterium, the phage injects its genetic material into the bacterial host where the phage is replicated to produce many new phages that then leave the host via cell lysis.

Due to the misuse of antibiotics, multiple drug-resistant pathogenic bacteria have increasingly emerged. This has increased the difficulty of treatment as these bacteria directly affect public health by diminishing the potency of existing antibiotics. Developing alternative therapeutic strategies is the urgent need to reduce the mortality and morbidity related to drug-resistant bacterial infections. In the past 10 to 20 years, nanomedicines have been widely studied and applied as an antibacterial agent. They have become a novel tool for fighting resistant bacteria. The most common innovative s

While the gut microbiome is composed of numerous bacteria, specific bacteria within the gut may play a significant role in carcinogenesis, progression, and metastasis of colorectal carcinoma (CRC). Certain microbial species are known to be associated with specific cancers; however, the interrelationship between bacteria and metastasis is still enigmatic. Mounting evidence suggests that bacteria participate in cancer organotropism during solid tumor metastasis.

Abstract Treating pancreatic ductal adenocarcinoma (PDAC) with systemic chemotherapeutic drugs has remained a challenge, due in part to the hypovascularized and poorly perfused nature of PDAC tumors, impeding the accumulation of systemically delivered drugs. Several clinical trials aimed at improving drug delivery in PDAC, through targeting of ECM components (HALO-301) or stromal angiogenic signaling (IPI-926-03) have unfortunately not been effective. However, the features that have interfered with systemic therapy in PDAC are potential advantages for the use of bacterial therapies, as bacteri

Owing to its unique mechanism of abundant pathogen-associated molecular patterns in antitumor immune responses, bacteria-based cancer immunotherapy has recently attracted wide attention. Compared to traditional cancer treatments such as surgery, chemotherapy, radiotherapy, and phototherapy, bacteria-based cancer immunotherapy exhibits the versatile capabilities for suppressing cancer thanks to its preferentially accumulating and proliferating within tumors. In particular, bacteria have demonstrated their anticancer effect through the toxins, and other active components from the cell membrane,

The antibiotic resistance of bacteria from the water column of various rivers and billabongs in north-eastern Victoria was studied during 1988-91. Two indices were used as measures of resistance: conventional disc-sensitivity tests with culturable bacteria, and the effect of antibiotics on the uptake of 14C-glucose and 14C-amino acids by native bacterial assemblages. Culturable bacteria were resistant to ampicillin, methicillin and penicillin but generally sensitive to nalidixic acid, neomycin, streptomycin, sulfafurazole and tetracycline.

Background:A major feature of chronic wounds is the loss of tissue, with the exposure of dermal components preventing primary closure and leading to bacterial colonization. Bacterial colonization has been proposed as one of the common underlying pathologies present in chronic wounds. The objective of this exploratory study was to identify bacteria cultured from chronic venous leg ulcers and test for proteolytic activity that degrades matrix substrates.Method:Bacteria were isolated, cultured, and identified from six subjects (average age = 62.8 years) over 2–10 months under an approved protocol

Purpose The major causes of mortality after allogeneic hematopoietic-cell transplantation (allo-HCT) are relapse, graft-versus-host disease (GVHD), and infection. We have reported previously that alterations in the intestinal flora are associated with GVHD, bacteremia, and reduced overall survival after allo-HCT. Because intestinal bacteria are potent modulators of systemic immune responses, including antitumor effects, we hypothesized that components of the intestinal flora could be associated with relapse after allo-HCT. Methods The intestinal microbiota of 541 patients admitted for allo-HCT

4083 Background: The presence of certain bacteria among or adjacent to tumor cells may contribute to colorectal cancer (CRC) development. However, the effect of the tumor microbiome on survival in CRC patients undergoing treatment is poorly understood. We hypothesize that intra-tumoral microbes correlate with overall survival (OS) in CRC patients. Methods: We obtained RNA-seq data from CRC tumor biopsies from patients treated at The Ohio State University Comprehensive Cancer Center as part of the Oncology Research Information Exchange Network (ORIEN).

SUMMARY Human oral bacteria interact with their environment by attaching to surfaces and establishing mixed-species communities. As each bacterial cell attaches, it forms a new surface to which other cells can adhere. Adherence and community development are spatiotemporal; such order requires communication. The discovery of soluble signals, such as autoinducer-2, that may be exchanged within multispecies communities to convey information between organisms has emerged as a new research direction. Direct-contact signals, such as adhesins and receptors, that elicit changes in gene expression afte

Abstract Over the past decade, infectious agents, including bacteria, have come under scrutiny for contributing to almost 16% of all tumors. Indeed, emerging data report a microbial presence in many cancer types, with breast cancer accumulating the most diverse bacterial population. Pathogen defense mechanisms, such as CHI3L1, contribute to bacterial elimination; however, CHI3L1 is overexpressed in several cancer types and correlates with poor prognosis and shorter survival. However, the connection between intra-tumoral bacteria and CHI3L1 and how they contribute to cancer growth has not been

Candidate Phyla Radiation (CPR) bacteria is a bacterial division composed mainly of candidate phyla bacteria with ultra-small cell sizes, streamlined genomes, and limited metabolic capacity, which are generally considered to survive in a parasitic or symbiotic manner. Despite their wide distribution and rich diversity, CPR bacteria have received little attention until recent years, and are therefore poorly understood. This review systematically summarizes the history of CPR research, the parasitic/symbiotic lifestyle, and the ecological distribution and unique metabolic features of CPR bacteri

Lichens are mutually symbiotic systems consisting of fungal and algal symbionts. While diverse lichen-forming fungal species are known, limited species of algae form lichens. Plasticity in the combination of fungal and algal species with different eco-physiological properties may contribute to the worldwide distribution of lichens, even in extreme habitats. Lichens have been studied systematically for more than 200 years; however, plasticity in fungal–algal/cyanobacterial symbiotic combinations is still unclear. In addition, the association between non-cyanobacterial bacteria and lichens has a
