Detection of Borrelia burgdorferi in historic tick samples and its relevance to the white-tailed deer population in New Hampshire [PDF]

open access: yes, 2018
The cases of Lyme disease in New Hampshire have increased over time. There are speculations that increasing number of Lyme disease cases in New Hampshire are due to environmental factors, such as warmer climate, white-footed mouse population, white ...

Microbial Contribution to Soiling and Its Impact on Photovoltaic Module Soiling in Arid Zones of the Atacama Desert

open access: yesAdvanced Sustainable Systems, EarlyView.
Microorganisms colonizing photovoltaic surfaces in the Atacama desert form biofilms that enhance particle adhesion and reduce energy yield. This study identifies UV‐resistant bacteria and carotenoid‐producing strains that interfere with PV performance.

Comparing methods for measuring phytoplankton biomass in aquaculture ponds

open access: yesAquaculture Environment Interactions, 2016
Algal biomass is important for aquaculture in terms of eutrophication, as a secondary metabolite threat, and as a food source for suspension feeders and benthos.

The genetic basis of host preference and resting behavior in the major African malaria vector, Anopheles arabiensis [PDF]

open access: yes, 2016
Malaria transmission is dependent on the propensity of Anopheles mosquitoes to bite humans (anthropophily) instead of other dead end hosts. Recent increases in the usage of Long Lasting Insecticide Treated Nets (LLINs) in Africa have been associated ...

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

open access: yesAdvanced Science, EarlyView.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

Identification of zones of preferential groundwater tracer transport using a mobile downhole fluorometer [PDF]

open access: yes, 2018
A mobile downhole fluorometer was used to detect zones of preferential groundwater tracer transport into an observation well. Identification of such zones is not possible if individual samples are collected over the well's entire screened interval ...

Gut Microbiota‐Derived Anandamide Mediates the Therapeutic Effects of Urolithin A on Alcohol‐Induced Cognitive and Social Dysfunction via CB1R‐DRD2‐RAP1 Signaling Axis

open access: yesAdvanced Science, EarlyView.
This study reveals that Urolithin A (UA) counteracts alcohol‐induced cognitive and social dysfunction (AICSD) via a gut microbiome‐dependent mechanism. UA‐enriched Bacteroids sartorii and Parabacteroids distasonis elevate anandamide (AEA), which activates the CB1R‐DRD2‐Rap1 signaling cascade to drive synaptic repair and reduce neuroinflammation ...

Expression in Escherichia coli of a cloned DNA sequence encoding the pre-S2 region of hepatitis B virus [PDF]

open access: yes, 1985
A DNA sequence encoding the entire pre-S2 region (amino acids 120-174; serotype ayw) of human hepatitis B virus envelope protein has been inserted into the lacZ gene of the plasmid pSKS105 yielding a recombinant, pWS3.

Highly Resolved Community Sewage Metagenomics Unveiling Landscape and Transmission Patterns of Antibiotic Resistome in Hong Kong Populations

open access: yesAdvanced Science, EarlyView.
A large‐scale, high‐resolution antimicrobial resistance (AMR) surveillance in Hong Kong community sewage combining short‐ and long‐read sequencing. The resistome profile is comprehensively characterized, and this upstream sampling strategy demonstrated superiority in reflecting the human gut resistome.

Optical Brightener Study of Spruce Creek [PDF]

open access: yes, 2010
Elevated bacteria levels in the Spruce Creek Watershed have led to shellfish bed closures in the Spruce Creek Estuary and impaired waters listings by the State of Maine. Since 2005, the Town of Kittery, Spruce Creek Association and numerous partners have
